              the Federal Register (44 U.S.C. 1510).

          It is prohibited to use NARA's official seal and the stylized Code 
              of Federal Regulations logo on any republication of this 
              material without the express, written permission of the 
              Archivist of the United States or the Archivist's designee. 
              Any person using NARA's official seals and logos in a manner 
              inconsistent with the provisions of 36 CFR part 1200 is

                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, July 1, 2017), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not accidentally dropped due to a printing or computer error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.

[[Page vii]]

    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

Stat. 816).

    Source: 41 FR 17902, Apr. 29, 1976, unless otherwise noted.



Sec. 104.1  Applicability.

    This part shall be applicable to hearings required by statute to be 
held in connection with the establishment of toxic pollutant effluent 
standards under section 307(a) of the Act.



Sec. 104.2  Definitions.

    As used in this part, the term:
    (a) Act means the Federal Water Pollution Control Act, as amended, 
33 U.S.C. 1251 et seq., Public Law 92-500, 86 Stat. 816.
    (b) Administrator means the Administrator of the Environmental 
Protection Agency, or any employee of the Agency to whom the 
Administrator may by order delegate his authority to carry out his 
functions under section 307(a) of the Act, or any person who shall by 
operation of law be authorized to carry out such functions.
    (c) Agency means the Environmental Protection Agency.
    (d) Hearing Clerk means the Hearing Clerk, U.S. Environmental 
Protection Agency, 401 M Street SW., Washington, DC 20460.
    (e) Party means the Environmental Protection Agency as the proponent 
of an effluent standard or standards, and any person who files an 
objection pursuant to Sec. 104.3 hereof.
    (f) Person means an individual, corporation, partnership, 
association, state, municipality or other political subdivision of a 
state, or any interstate body.
    (g) Effluent standard means any effluent standard or limitation, 
which may include a prohibition of any discharge, established or 
proposed to be established for any toxic pollutant under section 307(a) 
of the Act.
    (h) Presiding Officer means the Chief Administrative Law Judge of 
the Agency or a person designated by the Chief Administrative Law Judge 
or by the Administrator to preside at a hearing under this part, in 
accordance with Sec. 104.6 hereof.



Sec. 104.3  Notice of hearing; objection; public comment.

    (a) Notice of hearing. Whenever the Administrator publishes any 
proposed effluent standard, he shall simultaneously publish a notice of 
a public hearing to be held within thirty days following the date of 
publication of the proposed standard. Any person who has any objection 
to a proposed standard may file with the hearing clerk a concise 
statement of any such objection. No person may participate in the 
hearing on the proposed toxic pollutant effluent standards unless the 
hearing clerk has received within 25 days of the publication of the 
notice of the proposed standards a statement of objection as herein 
described. In exceptional circumstances and for good cause shown the 
Presiding Officer may allow an objection to be filed after the filing 
deadline prescribed in the preceding sentence, which good cause must 
include at a minimum lack of actual notice on the part of the objector 
or any

[[Page 6]]

representative of such objector of the proposed standards despite his 
exercise of due diligence, so long as such later filing will not cause 
undue delay in the proceedings or prejudice to any of the parties.
    (b) Objections. Any objection to a proposed standard which is filed 
pursuant to paragraph (a) of this section shall meet the following 
requirements:
    (1) It shall be filed in triplicate with the hearing clerk within 
the time prescribed in paragraph (a) of this section;
    (2) It shall state concisely and with particularity each portion of 
the proposed standard to which objection is taken; to the greatest 
extent feasible it shall state the basis for such objection;
    (3) To the greatest extent feasible it shall (i) state specifically 
the objector's proposed modification to any such standard proposed by 
the Agency to which objection is taken, (ii) set forth the reasons why 
such modification is sought, and (iii) identify and describe the 
scientific or other basis for such proposed modification, including 
reference to any pertinent scientific data or authority in support 
thereof.

Any objection which fails to comply with the foregoing provisions shall 
not be accepted for filing. The Presiding Officer shall promptly notify 
any person whose objection is not accepted for any of the reasons set 
forth in this section, stating the reasons therefor.
    (c) Data in support of objection or modification. In the event that 
the time prescribed for filing objections pursuant to paragraphs (a) and 
(b) of this section is insufficient to permit an objecting party to 
fully set forth with such objection the basis therefor together with the 
information and data specified in paragraph (b)(3) of this section, he 
may so state at the time of the filing of such objection, and file a 
more complete statement of such basis, information, and data 
(hereinafter referred to as ``supplemental data'') within the time 
prescribed by this paragraph (c). The supplemental data herein described 
shall be filed not later than 40 days following publication of the 
proposed effluent standards.
    (d) Public comment. The notice required under paragraph (a) of this 
section shall also provide for the submission to the Agency of written 
comments on the proposed rulemaking by interested persons not filing 
objections pursuant to this section as hereinabove described, and hence 
not participating in the hearing as parties. The notice shall fix a time 
deadline for the submission of such comments which shall be not later 
than the date set for commencement of the hearing. Such comments shall 
be received in evidence at the commencement of the hearing. The 
Administrator in making any decision based upon the record shall take 
into account the unavailability of cross-examination in determining the 
weight to be accorded such comments.
    (e) Promulgation in absence of objection. If no objection is filed 
pursuant to this section, then the Administrator shall promulgate the 
final standards on the basis of the Agency's statement of basis and 
purpose and any public comments received pursuant to paragraph (d) of 
this section.



Sec. 104.4  Statement of basis and purpose.

    Whenever the Administrator publishes a proposed effluent standard, 
the notice thereof published in the Federal Register shall include a 
statement of the basis and purpose of the standard or a summary thereof. 
This statement shall include:
    (a) The purpose of the proposed standard;
    (b) An explanation of how the proposed standard was derived;
    (c) Scientific and technical data and studies supporting the 
proposed standard or references thereto if the materials are published 
or otherwise readily available; and
    (d) Such other information as may be reasonably required to set 
forth fully the basis of the standard.


Where the notice of the proposed rulemaking summarizes the full 
statement of basis and purpose, or incorporates documents by reference, 
the documents thus summarized or incorporated by reference shall 
thereupon be made available by the Agency for inspection and copying by 
any interested person.



Sec. 104.5  Docket and record.

    Whenever the Administrator publishes a notice of hearing under this 
part, the hearing clerk shall promptly establish a docket for the 
hearing. The

[[Page 7]]

docket shall include all written objections filed by any party, any 
public comments received pursuant to Sec. 104.3(d), a verbatim 
transcript of the hearing, the statement of basis and purpose required 
by Sec. 104.4, and any supporting documents referred to therein, and 
other documents of exhibits that may be received in evidence or marked 
for identification by or at the direction of the Presiding Officer, or 
filed by any party in connection with the hearing. Copies of documents 
in the docket shall be available to any person upon payment to the 
Agency of such charges as the Agency may prescribe to cover the costs of 
duplication. The materials contained in the docket shall constitute the 
record.



Sec. 104.6  Designation of Presiding Officer.

    The Chief Administrative Law Judge of the Agency may preside 
personally at any hearing under this part, or he may designate another 
Administrative Law Judge as Presiding Officer for the hearing. In the 
event of the unavailability of any such Administrative Law Judge, the 
Administrator may designate a Presiding Officer. No person who has any 
personal pecuniary interest in the outcome of a proceeding under this 
part, or who has participated in the development or enforcement of any 
standard or proposed standard at issue in a proceeding hereunder, shall 
serve as Presiding Officer in such proceeding.



Sec. 104.7  Powers of Presiding Officer.

    The Presiding Officer shall have the duty to conduct a fair hearing 
within the time constraints imposed by section 307(a) of the Act. He 
shall take all necessary action to avoid delay and to maintain order. He 
shall have all powers necessary to these ends, including but not limited 
to the power to:
    (a) Rule upon motions and requests;
    (b) Change the time and place of the hearing, and adjourn the 
hearing from time to time or from place to place;
    (c) Examine and cross-examine witnesses;
    (d) Admit or exclude evidence; and
    (e) Require any part or all of the evidence to be submitted in 
writing and by a certain date.



Sec. 104.8  Prehearing conferences.

    Prehearing conferences are encouraged for the purposes of 
simplification of issues, identification and scheduling of evidence and 
witnesses, the establishment of an orderly framework for the 
proceedings, the expediting of the hearing, and such other purposes of a 
similar nature as may be appropriate.
    (a) The Presiding Officer on his own motion may, and at the request 
of any party made within 20 days of the proposal of standards hereunder 
shall, direct all parties to appear at a specified time and place for an 
initial hearing session in the nature of a prehearing conference. 
Matters taken up at the conference may include, without limitation:
    (1) Consideration and simplification of any issues of law or fact;
    (2) Identification, advance submission, marking for identification, 
consideration of any objections to admission, and admission of 
documentary evidence;
    (3) Possible stipulations of fact;
    (4) The identification of each witness expected to be called by each 
party, and the nature and substance of his expected testimony;
    (5) Scheduling of witnesses where practicable, and limitation of the 
number of witnesses where appropriate in order to avoid delay or 
repetition;
    (6) If desirable, the segregation of the hearing into separate 
segments for different provisions of the proposed effluent standards and 
the establishment of separate service lists;
    (7) Encouragement of objecting parties to agree upon and designate 
lead counsel for objectors with common interests so as to avoid 
repetitious questioning of witnesses.
    (b) The Presiding Officer may, following a prehearing conference, 
issue an order setting forth the agreements reached by the parties or 
representatives, the schedule of witnesses, and a statement of issues 
for the hearing. In addition such order may direct the parties to file 
and serve copies of documents or materials, file and serve lists of 
witnesses which may include a short summary of the expected testimony of 
each and, in the case of an expert witness, his curriculum vitae, and 
may contain such other directions as may

[[Page 8]]

be appropriate to facilitate the proceedings.



Sec. 104.9  Admission of evidence.

    (a) Where the Presiding Officer has directed identification of 
witnesses and production of documentation evidence by a certain date, 
the Presiding Officer may exclude any such evidence, or refuse to allow 
any witness to testify, when the witness was not identified or the 
document was not served by the time set by the Presiding Officer. Any 
such direction with respect to a party's case in chief shall not 
preclude the use of such evidence or testimony on rebuttal or response, 
or upon a showing satisfactory to the Presiding Officer that good cause 
existed for failure to serve testimony or a document or identify a 
witness by the time required. The Presiding Officer may require direct 
testimony to be in writing under oath and served by a certain date, and 
may exclude testimony not so served.
    (b) At the first prehearing conference, or at another time before 
the beginning of the taking of oral testimony to be set by the Presiding 
Officer, the statement of basis and purpose, together with any 
publications or reference materials cited therein, except where excluded 
by stipulation, shall be received in evidence.
    (c) The Presiding Officer may exclude evidence which is immaterial, 
irrelevant, unduly repetitious or cumulative, or would involve undue 
delay, or which, if hearsay, is not of the sort upon which responsible 
persons are accustomed to rely.
    (d) If relevant and material evidence is contained in a report or 
document containing immaterial or irrelevant matter, such immaterial or 
irrelevant matter may be excluded.
    (e) Whenever written testimony or a document or object is excluded 
from evidence by the Presiding Officer, it shall at the request of the 
proponent be marked for identification. Where oral testimony is 
permitted by the Presiding Officer, but the Presiding Officer excludes 
particular oral testimony, the party offering such testimony may make a 
brief offer of proof.
    (f) Any relevant and material documentary evidence, including but 
not limited to affidavits, published articles, and official documents, 
regardless of the availability of the affiant or author for cross-
examination, may be admitted in evidence, subject to the provisions of 
paragraphs (a), (c), and (d) of this section. The availability or 
nonavailability of cross-examination shall be considered as affecting 
the weight to be accorded such evidence in any decision based upon the 
record.
    (g) Official notice may be taken by the Presiding Officer or the 
Administrator of any matter which could be judicially noticed in the 
United States District Courts, and of other facts within the specialized 
knowledge and experience of the Agency. Opposing parties shall be given 
adequate opportunity to show the contrary.



Sec. 104.10  Hearing procedures.

    (a) Following the admission in evidence of the materials described 
in Sec. 104.9(b), the Agency shall have the right at the commencement 
of the hearing to supplement that evidence or to introduce additional 
relevant evidence. Thereafter the evidence of each objector shall be 
presented in support of its objection and any proposed modification. The 
Agency staff shall then be given an opportunity to rebut or respond to 
the objectors' presentation, including at its option the introduction of 
evidence which tends to support a standard or standards other than as 
set forth in the Agency's own initially proposed standards. In the event 
that evidence which tends to support such other standard or standards is 
offered and received in evidence, then the objectors may thereafter 
rebut or respond to any such new evidence.
    (b) The burden of proof as to any modification of any standard 
proposed by the Agency shall be upon the party who advocates such 
modification to show that the proposed modification is justified based 
upon a preponderance of the evidence.
    (c) Where necessary in order to prevent undue prolongation of the 
hearing, or to comply with time limitations set forth in the Act, the 
Presiding Officer may limit the number of witnesses who may testify, and 
the scope and extent of cross-examination.

[[Page 9]]

    (d) A verbatim transcript of the hearing shall be maintained and 
shall constitute a part of the record.
    (e) If a party objects to the admission or rejection of any evidence 
or to any other ruling of the Presiding Officer during the hearing, he 
shall state briefly the grounds of such objection. With respect to any 
ruling on evidence, it shall not be necessary for any party to claim an 
exception in order to preserve any right of subsequent review.
    (f) Any party may at any time withdraw his objection to a proposed 
effluent standard.



Sec. 104.11  Briefs and findings of fact.

    At the conclusion of the hearing, the Presiding Officer shall set a 
schedule for the submission by the parties of briefs and proposed 
findings of fact and conclusions. In establishing the aforesaid time 
schedule, the Presiding Officer shall consider the time constraints 
placed upon the parties and the Administrator by the statutory 
deadlines.



Sec. 104.12  Certification of record.

    As soon as possible after the hearing, the Presiding Officer shall 
transmit to the hearing clerk the transcript of the testimony and 
exhibits introduced in the hearing. The Presiding Officer shall attach 
to the original transcript his certificate stating that, to the best of 
his knowledge and belief, the transcript is a true transcript of the 
testimony given at the hearing except in such particulars as he shall 
specify, and that the exhibits transmitted are all the exhibits as 
introduced at the hearing with such exceptions as he shall specify.



Sec. 104.13  Interlocutory and post-hearing review of rulings of the
Presiding Officer; motions.

    (a) The Presiding Officer may certify a ruling for interlocutory 
review by the Administrator where a party so requests and the Presiding 
Officer concludes that (1) the ruling from which review is sought 
involves an important question as to which there is substantial ground 
for difference of opinion, and (2) either (i) a subsequent reversal of 
his ruling would be likely to result in substantial delay or expense if 
left to the conclusion of the proceedings, or (ii) a ruling on the 
question by the Administrator would be of material assistance in 
expediting the hearing. The certificate shall be in writing and shall 
specify the material relevant to the ruling certified. If the 
Administrator determines that interlocutory review is not warranted, he 
may decline to consider the ruling which has been certified.
    (b) Where the Presiding Officer declines to certify a ruling the 
party who had requested certification may apply to the Administrator for 
interlocutory review, or the Administrator may on his own motion direct 
that any matter be submitted to him for review, subject to the standards 
for review set forth in paragraph (a) of this section. An application 
for review shall be in writing and shall briefly state the grounds 
relied on. If the Administrator takes no action with respect to such 
application for interlocutory review within 15 days of its filing, such 
application shall be deemed to have been denied.
    (c) Unless otherwise ordered by the Presiding Officer or the 
Administrator, the hearing shall continue pending consideration by the 
Administrator of any ruling or request for interlocutory review.
    (d) Unless otherwise ordered by the Presiding Officer or the 
Administrator, briefs in response to any application for interlocutory 
review may be filed by any party within five days of the filing of the 
application for review.
    (e) Failure to request or obtain interlocutory review does not waive 
the rights of any party to complain of a ruling following completion of 
the hearing. Within five days following the close of a hearing under 
this part, any party may apply to the Administrator for post-hearing 
review of any procedural ruling, or any ruling made by the Presiding 
Officer concerning the admission or exclusion of evidence to which 
timely objection was made. Within seven days following the filing of any 
such application any other party may file a brief in response thereto.
    (f) If the Administrator on review under paragraph (e) of this 
section determines that evidence was improperly excluded, he may order 
its admission

[[Page 10]]

without remand for further proceedings, or may remand with such 
instructions as he deems appropriate concerning cross-examination, or 
opportunity for any party to submit further evidence, with respect to 
such evidence as he directs should be admitted. In making his 
determination whether to remand, the Administrator shall consider 
whether the statutory time restraints permit a remand, and whether it 
would be constructive to allow cross-examination or further evidence 
with respect to the newly admitted evidence. If evidence is admitted 
without cross-examination, the Administrator shall consider the lack of 
opportunity for cross-examination in determining the weight to be given 
such evidence.
    (g) Motions shall be brief, in writing, and may be filed at any time 
following the publication of the proposed effluent standards, unless 
otherwise ordered by the Presiding Officer or the Administrator. Unless 
otherwise ordered or provided in these rules, responses to motions may 
be filed within seven days of the actual filing of the motion with the 
hearing clerk.



Sec. 104.14  Tentative and final decision by the Administrator.

    (a) As soon as practicable following the certification of the record 
and the filing by the parties of briefs and proposed findings of fact 
and conclusions under Sec. 104.11, the Administrator, with such staff 
assistance as he deems necessary and appropriate, shall review the 
entire record and prepare and file a tentative decision based thereon. 
The tentative decision shall include findings of fact and conclusions, 
and shall be filed with the hearing clerk who shall at once transmit a 
copy thereof to each party who participated at the hearing, or his 
attorney or other representative.
    (b) Upon filing of the tentative decision, the Administrator may 
allow a reasonable time for the parties to file with him any exceptions 
to the tenative decision, a brief in support of such exceptions 
containing appropriate references to the record, and any proposed 
changes in the tentative decision. Such materials shall, upon 
submission, become part of the record. As soon as practicable after the 
filing thereof the Administrator shall prepare and file a final 
decision, copies of which shall be transmitted to the parties or their 
representatives in the manner prescribed in paragraph (a) of this 
section.
    (c) In the event that the Administrator determines that due and 
timely execution of his functions, including compliance with time 
limitations established by law, imperatively and unavoidably so 
requires, he may omit the preparation and filing of the tentative 
decision and related procedures set forth in paragraph (b) of this 
section, and shall instead prepare and file a final decision, copies of 
which shall be transmitted to the parties or their representatives in 
the manner prescribed in paragraph (a) of this section.
    (d) Any decision rendered by the Administrator pursuant to this 
section shall include a statement of his findings and conclusions, and 
the reasons and basis therefor, and shall indicate the toxic pollutant 
effluent standard or standards which the Administrator is promulgating 
or intends to promulgate based thereon.



Sec. 104.15  Promulgation of standards.

    Upon consideration of the record, at the time of his final decision 
the Administrator shall determine whether the proposed effluent standard 
or standards should be promulgated as proposed, or whether any 
modification thereof is justified based upon a proponderance of the 
evidence adduced at the hearing, regardless of whether or not such 
modification was actually proposed by any objecting party. If he 
determines that a modification is not justified, he shall promulgate the 
standard or standards as proposed. If he determines that a modification 
is justified, he shall promulgate a standard or standards as so 
modified.



Sec. 104.16  Filing and time.

    (a) All documents or papers required or authorized by the foregoing 
provisions of this part including, but not limited to, motions, 
applications for review, and briefs, shall be filed in duplicate with 
the hearing clerk, except as otherwise expressly provided in these 
rules. Any document or paper so required or authorized to be filed with

[[Page 11]]

the hearing clerk, if it is filed during the course of the hearing, 
shall be also filed with the Presiding Officer. A copy of each document 
or paper filed by any party with the Presiding Officer, with the hearing 
clerk, or with the Administrator shall be served upon all other parties, 
except to the extent that the list of parties to be so served may be 
modified by order of the Presiding Officer, and each such document or 
paper shall be accompanied by a certificate of such service.
    (b) A party may be represented in any proceeding under this part by 
an attorney or other authorized representative. When any document or 
paper is required under these rules to be served upon a party such 
service shall be made upon such attorney or other representative.
    (c) Except where these rules or an order of the Presiding Officer 
require receipt of a document by a certain date, any document or paper 
required or authorized to be filed by this part shall be deemed to be 
filed when postmarked, or in the case of papers delivered other than by 
mail, when received by the hearing clerk.
    (d) Sundays and legal holidays shall be included in computing the 
time allowed for the filing of any document or paper, provided, that 
when such time expires on a Sunday or legal holiday, such period shall 
be extended to include the next following business day.

because of the alleged results of any effluent limitation or order 
issued under the Act, or any representative of such employee, may submit 
a request for an investigation under this part to the Regional 
Administrator of the region in which such discrimination is alleged to 
have occurred.



Sec. 108.4  Investigation by Regional Administrator.

    Upon receipt of any request meeting the requirements of Sec. 108.3, 
the Regional Administrator shall conduct a full investigation of the 
matter, in order to determine whether the request may be related to an 
effluent limitation or order under the Act. Following the investigation, 
the Regional Administrator shall notify the employee requesting the 
investigation (or the employee's representative) and the employer of 
such employee, in writing, of his preliminary findings and conclusions. 
The employee, the representative of such employee, or the employer may 
within fifteen days following receipt of the preliminary findings and 
conclusions of the Regional Administrator request a hearing under this 
part. Upon receipt of such a request, the Regional Administrator, with 
the concurrence of the Chief Administrative Law Judge, shall publish 
notice of a hearing to be held not less than 30 days following the date 
of such publication where he determines that there are factual issues 
concerning the existence of the alleged discrimination or its 
relationship to an effluent limitation or order under the Act. The 
notice shall specify a date before which any party (or representative of 
such party) may submit a request to appear.



Sec. 108.5  Procedure.

    Any hearing held pursuant to this part shall be of record and shall 
be conducted according to the requirements of 5 U.S.C. 554. The

    Source: 36 FR 22485, Nov. 25, 1971, unless otherwise noted.



Sec. 109.1  Applicability.

    The criteria in this part are provided to assist State, local and 
regional agencies in the development of oil removal contingency plans 
for the inland navigable waters of the United States and all areas other 
than the high seas, coastal and contiguous zone waters, coastal and 
Great Lakes ports and harbors and such other areas as may be agreed upon 
between the Environmental Protection Agency and the Department of 
Transportation in accordance with section 11(j)(1)(B) of the Federal 
Act, Executive Order No. 11548 dated July 20, 1970 (35 FR 11677) and 
Sec. 306.2 of the National Oil and Hazardous Materials Pollution 
Contingency Plan (35 FR 8511).



Sec. 109.2  Definitions.

    As used in these guidelines, the following terms shall have the 
meaning indicated below:
    (a) Oil means oil of any kind or in any form, including, but not 
limited to, petroleum, fuel oil, sludge, oil refuse, and oil mixed with 
wastes other than dredged spoil.
    (b) Discharge includes, but is not limited to, any spilling, 
leaking, pumping, pouring, emitting, emptying, or dumping.
    (c) Remove or removal refers to the removal of the oil from the 
water and shorelines or the taking of such other actions as may be 
necessary to minimize or mitigate damage to the public health or 
welfare, including, but not limited to, fish, shellfish, wildlife, and 
public and private property, shorelines, and beaches.
    (d) Major disaster means any hurricane, tornado, storm, flood, high 
water, wind-driven water, tidal wave, earthquake, drought, fire, or 
other catastrophe in any part of the United States which, in the 
determination of the President, is or threatens to become of sufficient 
severity and magnitude to warrant disaster assistance by the Federal 
Government to supplement the efforts and available resources of States 
and local governments and relief organizations in alleviating the 
damage, loss, hardship, or suffering caused thereby.

[[Page 16]]

    (e) United States means the States, the District of Columbia, the 
Commonwealth of Puerto Rico, the Canal Zone, Guam, American Samoa, the 
Virgin Islands, and the Trust Territory of the Pacific Islands.
    (f) Federal Act means the Federal Water Pollution Control Act, as 
amended, 33 U.S.C. 1151 et seq.



Sec. 109.3  Purpose and scope.

    The guidelines in this part establish minimum criteria for the 
development and implementation of State, local, and regional contingency 
plans by State and local governments in consultation with private 
interests to insure timely, efficient, coordinated and effective action 
to minimize damage resulting from oil discharges. Such plans will be 
directed toward the protection of the public health or welfare of the 
United States, including, but not limited to, fish, shellfish, wildlife, 
and public and private property, shorelines, and beaches. The 
development and implementation of such plans shall be consistent with 
the National Oil and Hazardous Materials Pollution Contingency Plan. 
State, local and regional oil removal contingency plans shall provide 
for the coordination of the total response to an oil discharge so that 
contingency organizations established thereunder can function 
independently, in conjunction with each other, or in conjunction with 
the National and Regional Response Teams established by the National Oil 
and Hazardous Materials Pollution Contingency Plan.



Sec. 109.4  Relationship to Federal response actions.

    The National Oil and Hazardous Materials Pollution Contingency Plan 
provides that the Federal on-scene commander shall investigate all 
reported spills. If such investigation shows that appropriate action is 
being taken by either the discharger or non-Federal entities, the 
Federal on-scene commander shall monitor and provide advice or 
assistance, as required. If appropriate containment or cleanup action is 
not being taken by the discharger or non-Federal entities, the Federal 
on-scene commander will take control of the response activity in 
accordance with section 11(c)(1) of the Federal Act.



Sec. 109.5  Development and implementation criteria for State, 
local and regional oil removal contingency plans.

    Criteria for the development and implementation of State, local and 
regional oil removal contingency plans are:
    (a) Definition of the authorities, responsibilities and duties of 
all persons, organizations or agencies which are to be involved or could 
be involved in planning or directing oil removal operations, with 
particular care to clearly define the authorities, responsibilities and 
duties of State and local governmental agencies to avoid unnecessary 
duplication of contingency planning activities and to minimize the 
potential for conflict and confusion that could be generated in an 
emergency situation as a result of such duplications.
    (b) Establishment of notification procedures for the purpose of 
early detection and timely notification of an oil discharge including:
    (1) The identification of critical water use areas to facilitate the 
reporting of and response to oil discharges.
    (2) A current list of names, telephone numbers and addresses of the 
responsible persons and alternates on call to receive notification of an 
oil discharge as well as the names, telephone numbers and addresses of 
the organizations and agencies to be notified when an oil discharge is 
discovered.
    (3) Provisions for access to a reliable communications system for 
timely notification of an oil discharge and incorporation in the 
communications system of the capability for interconnection with the 
communications systems established under related oil removal contingency 
plans, particularly State and National plans.
    (4) An established, prearranged procedure for requesting assistance 
during a major disaster or when the situation exceeds the response 
capability of the State, local or regional authority.
    (c) Provisions to assure that full resource capability is known and 
can be committed during an oil discharge situation including:

[[Page 17]]

    (1) The identification and inventory of applicable equipment, 
materials and supplies which are available locally and regionally.
    (2) An estimate of the equipment, materials and supplies which would 
be required to remove the maximum oil discharge to be anticipated.
    (3) Development of agreements and arrangements in advance of an oil 
discharge for the acquisition of equipment, materials and supplies to be 
used in responding to such a discharge.
    (d) Provisions for well defined and specific actions to be taken 
after discovery and notification of an oil discharge including:
    (1) Specification of an oil discharge response operating team 
consisting of trained, prepared and available operating personnel.
    (2) Predesignation of a properly qualified oil discharge response 
coordinator who is charged with the responsibility and delegated 
commensurate authority for directing and coordinating response 
operations and who knows how to request assistance from Federal 
authorities operating under existing national and regional contingency 
plans.
    (3) A preplanned location for an oil discharge response operations 
center and a reliable communications system for directing the 
coordinated overall response operations.
    (4) Provisions for varying degrees of response effort depending on 
the severity of the oil discharge.
    (5) Specification of the order of priority in which the various 
water uses are to be protected where more than one water use may be 
adversely affected as a result of an oil discharge and where response 
operations may not be adequate to protect all uses.
    (e) Specific and well defined procedures to facilitate recovery of 
damages and enforcement measures as provided for by State and local 
statutes and ordinances.



Sec. 109.6  Coordination.

    For the purposes of coordination, the contingency plans of State and 
local governments should be developed and implemented in consultation 
with private interests. A copy of any oil removal contingency plan 
developed by State and local governments should be forwarded to the 
Council on Environmental Quality upon request to facilitate the 
coordination of these contingency plans with the National Oil and 
Hazardous Materials Pollution Contingency Plan.

of Pollution from Ships, 1973, as modified by the Protocol of 1978 
relating thereto, Annex I, which regulates pollution from oil and which 
entered into force on October 2, 1983;
    Navigable waters means waters of the United States, including the 
territorial seas.

[[Page 18]]

    (1) For purposes of the Clean Water Act, 33 U.S.C. 1251 et seq. and 
its implementing regulations, subject to the exclusions in paragraph (2) 
of this section, the term ``waters of the United States'' means:
    (i) All waters which are currently used, were used in the past, or 
may be susceptible to use in interstate or foreign commerce, including 
all waters which are subject to the ebb and flow of the tide;
    (ii) All interstate waters, including interstate wetlands;
    (iii) The territorial seas;
    (iv) All impoundments of waters otherwise identified as waters of 
the United States under this section;
    (v) All tributaries, as defined in paragraph (3)(iii) of this 
definition, of waters identified in paragraphs (1)(i) through (iii) of 
this definition;
    (vi) All waters adjacent to a water identified in paragraphs (1)(i) 
through (v) of this definition, including wetlands, ponds, lakes, 
oxbows, impoundments, and similar waters;
    (vii) All waters in paragraphs (1)(vii)(A) through (E) of this 
definition where they are determined, on a case-specific basis, to have 
a significant nexus to a water identified in paragraphs (1)(i) through 
(iii) of this definition. The waters identified in each of paragraphs 
(1)(vii)(A) through (E) of this definition are similarly situated and 
shall be combined, for purposes of a significant nexus analysis, in the 
watershed that drains to the nearest water identified in paragraphs 
(1)(i) through (iii) of this definition. Waters identified in this 
paragraph shall not be combined with waters identified in paragraph 
(1)(vi) of this definition when performing a significant nexus analysis. 
If waters identified in this paragraph are also an adjacent water under 
paragraph (1)(vi), they are an adjacent water and no case-specific 
significant nexus analysis is required.
    (A) Prairie potholes. Prairie potholes are a complex of glacially 
formed wetlands, usually occurring in depressions that lack permanent 
natural outlets, located in the upper Midwest.
    (B) Carolina bays and Delmarva bays. Carolina bays and Delmarva bays 
are ponded, depressional wetlands that occur along the Atlantic coastal 
plain.
    (C) Pocosins. Pocosins are evergreen shrub and tree dominated 
wetlands found predominantly along the Central Atlantic coastal plain.

depression, soils with poor drainage, mild, wet winters and hot, dry 
summers.
    (E) Texas coastal prairie wetlands. Texas coastal prairie wetlands 
are freshwater wetlands that occur as a mosaic of depressions, ridges, 
intermound flats, and mima mound wetlands located along the Texas Gulf 
Coast.
    (viii) All waters located within the 100-year floodplain of a water

waters located within 4,000 feet of the high tide line or ordinary high 
water mark of a water identified in paragraphs (1)(i) through (v) of 
this definition where they are determined on a case-specific basis to 
have a significant nexus to a water identified in paragraphs (1)(i) 
through (iii) of this definition. For waters determined to have a 
significant nexus, the entire water is a water of the United States if a 
portion is located within the 100-year floodplain of a water identified 
in paragraphs (1)(i) through (iii) of this definition or within 4,000 
feet of the high tide line or ordinary high water mark. Waters 
identified in this paragraph shall not be combined with waters 
identified in paragraph (1)(vi) of this definition when performing a 
significant nexus analysis. If waters identified in this paragraph are 
also an adjacent water under paragraph (1)(vi), they are an adjacent 
water and no case-specific significant nexus analysis is required.
    (2) The following are not ``waters of the United States'' even where 
they otherwise meet the terms of paragraphs (1)(iv) through (viii) of 
this section.
    (i) Waste treatment systems (other than cooling ponds meeting the

Water Act jurisdiction remains with EPA.
    (iii) The following ditches:
    (A) Ditches with ephemeral flow that are not a relocated tributary 
or excavated in a tributary.
    (B) Ditches with intermittent flow that are not a relocated 
tributary, excavated in a tributary, or drain wetlands.
    (C) Ditches that do not flow, either directly or through another 
water, into a water identified in paragraphs (1)(i) through (iii) of 
this definition.
    (iv) The following features:
    (A) Artificially irrigated areas that would revert to dry land 
should application of water to that area cease;
    (B) Artificial, constructed lakes and ponds created in dry land such 
as farm and stock watering ponds, irrigation ponds, settling basins, 
fields flooded for rice growing, log cleaning ponds, or cooling ponds;
    (C) Artificial reflecting pools or swimming pools created in dry 
land;
    (D) Small ornamental waters created in dry land;
    (E) Water-filled depressions created in dry land incidental to 
mining or construction activity, including pits excavated for obtaining 
fill, sand, or gravel that fill with water;
    (F) Erosional features, including gullies, rills, and other 
ephemeral features that do not meet the definition of tributary, non-
wetland swales, and lawfully constructed grassed waterways; and
    (G) Puddles.
    (v) Groundwater, including groundwater drained through subsurface 
drainage systems.

groundwater recharge basins; percolation ponds built for wastewater 
recycling; and water distributary structures built for wastewater 
recycling.
    (3) In this definition, the following terms apply:
    (i) Adjacent. The term adjacent means bordering, contiguous, or 
neighboring a water identified in paragraphs (1)(i) through (v) of this 
definition, including waters separated by constructed dikes or barriers, 
natural river berms, beach dunes, and the like. For purposes of 
adjacency, an open water such as a pond or lake includes any wetlands 
within or abutting its ordinary high water mark. Adjacency is not 
limited to waters located laterally to a water identified in paragraphs 
(1)(1) through (v) of this definition. Adjacent waters also include all 
waters that connect segments of a water identified in paragraphs (1)(i) 
through (v) or are located at the head of a water identified in 
paragraphs (1)(i) through (v) of this definition and are bordering, 
contiguous, or neighboring such water. Waters being used for established 
normal farming, ranching, and silviculture activities (33 U.S.C. 
1344(f)) are not adjacent.
    (ii) Neighboring. The term neighboring means:
    (A) All waters located within 100 feet of the ordinary high water 
mark of a water identified in paragraphs (1)(i) through (v) of this 
definition. The entire water is neighboring if a portion is located 
within 100 feet of the ordinary high water mark;
    (B) All waters located within the 100-year floodplain of a water 
identified in paragraphs (1)(i) through (v) of this definition and not 
more than 1,500 feet from the ordinary high water mark of such water. 
The entire water is neighboring if a portion is located within 1,500 
feet of the ordinary high water mark and within the 100-year floodplain;
    (C) All waters located within 1,500 feet of the high tide line of a 
water identified in paragraphs (1)(i) or (iii) of this definition, and 
all waters within 1,500 feet of the ordinary high water mark of the 
Great Lakes. The entire water is neighboring if a portion is located 
within 1,500 feet of the high tide line or within 1,500 feet of the 
ordinary high water mark of the Great Lakes.
    (iii) Tributary and tributaries. The terms tributary and tributaries 
each mean a water that contributes flow, either directly or through 
another water (including an impoundment identified in paragraph (1)(iv) 
of this section), to

[[Page 20]]

a water identified in paragraphs (1)(i) through (iii) of this definition 
that is characterized by the presence of the physical indicators of a 
bed and banks and an ordinary high water mark. These physical indicators 
demonstrate there is volume, frequency, and duration of flow sufficient 
to create a bed and banks and an ordinary high water mark, and thus to 
qualify as a tributary. A tributary can be a natural, man-altered, or 
man-made water and includes waters such as rivers, streams, canals, and 
ditches not excluded under paragraph (2) of this definition. A water 
that otherwise qualifies as a tributary under this definition does not 
lose its status as a tributary if, for any length, there are one or more 
constructed breaks (such as bridges, culverts, pipes, or dams), or one 
or more natural breaks (such as wetlands along the run of a stream, 
debris piles, boulder fields, or a stream that flows underground) so 
long as a bed and banks and an ordinary high water mark can be 
identified upstream of the break. A water that otherwise qualifies as a 
tributary under this definition does not lose its status as a tributary 
if it contributes flow through a water of the United States that does 
not meet the definition of tributary or through a non-jurisdictional 
water to a water identified in paragraphs (1)(i) through (iii) of this 
definition.
    (iv) Wetlands. The term wetlands means those areas that are 
inundated or saturated by surface or groundwater at a frequency and 
duration sufficient to support, and that under normal circumstances do 
support, a prevalence of vegetation typically adapted for life in 
saturated soil conditions. Wetlands generally include swamps, marshes, 
bogs, and similar areas.
    (v) Significant nexus. The term significant nexus means that a 
water, including wetlands, either alone or in combination with other 
similarly situated waters in the region, significantly affects the 
chemical, physical, or biological integrity of a water identified in 
paragraphs (1)(i) through (iii) of this definition. The term ``in the 
region'' means the watershed that drains to the nearest water identified 
in paragraphs (1)(i) through (iii) of this definition. For an effect to 
be significant, it must be more than speculative or insubstantial. 
Waters are similarly situated when they function alike and are 
sufficiently close to function together in affecting downstream waters. 
For purposes of determining whether or not a water has a significant 
nexus, the water's effect on downstream (1)(i) through (iii) waters 
shall be assessed by evaluating the aquatic functions identified in 
paragraphs (3)(v)(A) through (I) of this definition. A water has a 
significant nexus when any single function or combination of functions 
performed by the water, alone or together with similarly situated waters 
in the region, contributes significantly to the chemical, physical, or 
biological integrity of the nearest water identified in paragraphs 
(1)(i) through (iii) of this definition. Functions relevant to the 
significant nexus evaluation are the following:
    (A) Sediment trapping,
    (B) Nutrient recycling,
    (C) Pollutant trapping, transformation, filtering, and transport,
    (D) Retention and attenuation of flood waters,
    (E) Runoff storage,
    (F) Contribution of flow,
    (G) Export of organic matter,
    (H) Export of food resources, and
    (I) Provision of life cycle dependent aquatic habitat (such as 
foraging, feeding, nesting, breeding, spawning, or use as a nursery 
area) for species located in a water identified in paragraphs (1)(i) 
through (iii) of this definition.
    (vi) Ordinary high water mark. The term ordinary high water mark 
means that line on the shore established by the fluctuations of water 
and indicated by physical characteristics such as a clear, natural line 
impressed on the bank, shelving, changes in the character of soil, 
destruction of terrestrial vegetation, the presence of litter and 
debris, or other appropriate means that consider the characteristics of 
the surrounding areas.
    (vii) High tide line. The term high tide line means the line of 
intersection of the land with the water's surface at the maximum height 
reached by a rising tide. The high tide line may be determined, in the 
absence of actual data, by a line of oil or scum along shore objects, a 
more or less continuous deposit

[[Page 21]]

of fine shell or debris on the foreshore or berm, other physical 
markings or characteristics, vegetation lines, tidal gages, or other 
suitable means that delineate the general height reached by a rising 
tide. The line encompasses spring high tides and other high tides that 
occur with periodic frequency but does not include storm surges in which 
there is a departure from the normal or predicted reach of the tide due 
to the piling up of water against a coast by strong winds such as those 
accompanying a hurricane or other intense storm.
    NPDES means National Pollutant Discharge Elimination System;
    Sheen means an iridescent appearance on the surface of water;
    Sludge means an aggregate of oil or oil and other matter of any kind 
in any form other than dredged spoil having a combined specific gravity 
equivalent to or greater than water;
    United States means the States, the District of Columbia, the 
Commonwealth of Puerto Rico, Guam, American Samoa, the Virgin Islands, 
and the Trust Territory of the Pacific Islands;

FR 7421, Feb. 28, 1996; 80 FR 37106, June 29, 2015]



Sec. 110.2  Applicability.

    The regulations of this part apply to the discharge of oil 
prohibited by section 311(b)(3) of the Act.

[61 FR 7421, Feb. 28, 1996]



Sec. 110.3  Discharge of oil in such quantities as ``may be harmful''
pursuant to section 311(b)(4) of the Act.

    For purposes of section 311(b)(4) of the Act, discharges of oil in 
such quantities that the Administrator has determined may be harmful to 
the public health or welfare or the environment of the United States 
include discharges of oil that:
    (a) Violate applicable water quality standards; or
    (b) Cause a film or sheen upon or discoloration of the surface of 
the water or adjoining shorelines or cause a sludge or emulsion to be 
deposited beneath the surface of the water or upon adjoining shorelines.

[61 FR 7421, Feb. 28, 1996]



Sec. 110.4  Dispersants.

    Addition of dispersants or emulsifiers to oil to be discharged that 
would circumvent the provisions of this part is prohibited.

[52 FR 10719, Apr. 2, 1987. Redesignated at 61 FR 7421, Feb. 28, 1996]



Sec. 110.5  Discharges of oil not determined ``as may be harmful'' 
pursuant to Section 311(b)(3) of the Act.

    Notwithstanding any other provisions of this part, the Administrator 
has not determined the following discharges of oil ``as may be harmful'' 
for purposes of section 311(b) of the Act:
    (a) Discharges of oil from a properly functioning vessel engine 
(including an engine on a public vessel) and any discharges of such oil 
accumulated in the bilges of a vessel discharged in compliance with 
MARPOL 73/78, Annex I, as provided in 33 CFR part 151, subpart A;
    (b) Other discharges of oil permitted under MARPOL 73/78, Annex I, 
as provided in 33 CFR part 151, subpart A; and
    (c) Any discharge of oil explicitly permitted by the Administrator 
in connection with research, demonstration projects, or studies relating 
to the prevention, control, or abatement of oil pollution.

[61 FR 7421, Feb. 28, 1996]



Sec. 110.6  Notice.

    Any person in charge of a vessel or of an onshore or offshore 
facility shall, as soon as he or she has knowledge of any discharge of 
oil from such vessel or facility in violation of section 311(b)(3) of 
the Act, immediately notify the National Response Center (NRC) (800-424-
8802; in the Washington, DC metropolitan area, 202-426-2675). If direct 
reporting to the NRC is not practicable, reports may be made to the 
Coast Guard or EPA predesignated On-Scene Coordinator (OSC) for the 
geographic area where the discharge occurs. All such reports shall be 
promptly relayed to the NRC. If it is not possible to notify the NRC or 
the predesignated OCS immediately, reports may be made immediately to 
the nearest Coast Guard unit, provided that the person in charge of the 
vessel or onshore or offshore facility notifies the NRC as soon as 
possible. The reports shall be made

Sec. 112.1  General applicability.

    (a)(1) This part establishes procedures, methods, equipment, and 
other requirements to prevent the discharge of oil from non-
transportation-related onshore and offshore facilities into or upon the 
navigable waters of the

[[Page 23]]

United States or adjoining shorelines, or into or upon the waters of the 
contiguous zone, or in connection with activities under the Outer 
Continental Shelf Lands Act or the Deepwater Port Act of 1974, or that 
may affect natural resources belonging to, appertaining to, or under the 
exclusive management authority of the United States (including resources 
under the Magnuson Fishery Conservation and Management Act).
    (2) As used in this part, words in the singular also include the 
plural and words in the masculine gender also include the feminine and 
vice versa, as the case may require.
    (b) Except as provided in paragraph (d) of this section, this part 
applies to any owner or operator of a non-transportation-related onshore 
or offshore facility engaged in drilling, producing, gathering, storing, 
processing, refining, transferring, distributing, using, or consuming 
oil and oil products, which due to its location, could reasonably be 
expected to discharge oil in quantities that may be harmful, as 
described in part 110 of this chapter, into or upon the navigable waters 
of the United States or adjoining shorelines, or into or upon the waters 
of the contiguous zone, or in connection with activities under the Outer 
Continental Shelf Lands Act or the Deepwater Port Act of 1974, or that 
may affect natural resources belonging to, appertaining to, or under the 
exclusive management authority of the United States (including resources 
under the Magnuson Fishery Conservation and Management Act) that has oil 
in:
    (1) Any aboveground container;
    (2) Any completely buried tank as defined in Sec. 112.2;
    (3) Any container that is used for standby storage, for seasonal 
storage, or for temporary storage, or not otherwise ``permanently 
closed'' as defined in Sec. 112.2;
    (4) Any ``bunkered tank'' or ``partially buried tank'' as defined in 
Sec. 112.2, or any container in a vault, each of which is considered an 
aboveground storage container for purposes of this part.
    (c) As provided in section 313 of the Clean Water Act (CWA), 
departments, agencies, and instrumentalities of the Federal government 
are subject to this part to the same extent as any person.
    (d) Except as provided in paragraph (f) of this section, this part 
does not apply to:
    (1) The owner or operator of any facility, equipment, or operation 
that is not subject to the jurisdiction of the Environmental Protection 
Agency (EPA) under section 311(j)(1)(C) of the CWA, as follows:
    (i) Any onshore or offshore facility, that due to its location, 
could not reasonably be expected to have a discharge as described in 
paragraph (b) of this section. This determination must be based solely 
upon consideration of the geographical and location aspects of the 
facility (such as proximity to navigable waters or adjoining shorelines, 
land contour, drainage, etc.) and must exclude consideration of manmade 
features such as dikes, equipment or other structures, which may serve 
to restrain, hinder, contain, or otherwise prevent a discharge as 
described in paragraph (b) of this section.
    (ii) Any equipment, or operation of a vessel or transportation-
related onshore or offshore facility which is subject to the authority 
and control of the U.S. Department of Transportation, as defined in the 
Memorandum of Understanding between the Secretary of Transportation and 
the Administrator of EPA, dated November 24, 1971 (appendix A of this 
part).
    (iii) Any equipment, or operation of a vessel or onshore or offshore 
facility which is subject to the authority and control of the U.S. 
Department of Transportation or the U.S. Department of the Interior, as 
defined in the Memorandum of Understanding between the Secretary of 
Transportation, the Secretary of the Interior, and the Administrator of 
EPA, dated November 8, 1993 (appendix B of this part).
    (2) Any facility which, although otherwise subject to the 
jurisdiction of EPA, meets both of the following requirements:
    (i) The completely buried storage capacity of the facility is 42,000 
U.S. gallons or less of oil. For purposes of this exemption, the 
completely buried storage capacity of a facility excludes the capacity 
of a completely buried tank,

[[Page 24]]

as defined in Sec. 112.2, and connected underground piping, underground 
ancillary equipment, and containment systems, that is currently subject 
to all of the technical requirements of part 280 of this chapter or all 
of the technical requirements of a State program approved under part 281 
of this chapter, or the capacity of any underground oil storage tanks 
deferred under 40 CFR part 280 that supply emergency diesel generators 
at a nuclear power generation facility licensed by the Nuclear 
Regulatory Commission and subject to any Nuclear Regulatory Commission 
provision regarding design and quality criteria, including, but not 
limited to, 10 CFR part 50. The completely buried storage capacity of a 
facility also excludes the capacity of a container that is ``permanently 
closed,'' as defined in Sec. 112.2 and the capacity of intra-facility 
gathering lines subject to the regulatory requirements of 49 CFR part 
192 or 195.

container;
    (D) The capacity of a container for heating oil used solely at a 
single-family residence;
    (E) The capacity of pesticide application equipment and related mix 
containers.
    (F) The capacity of any milk and milk product container and 
associated piping and appurtenances.
    (3) Any offshore oil drilling, production, or workover facility that 
is subject to the notices and regulations of the Minerals Management 
Service, as specified in the Memorandum of Understanding between the 
Secretary of Transportation, the Secretary of the Interior, and the 
Administrator of EPA, dated November 8, 1993 (appendix B of this part).
    (4) Any completely buried storage tank, as defined in Sec. 112.2, 
and connected underground piping, underground ancillary equipment, and 
containment systems, at any facility, that is subject to all of the 
technical requirements of part 280 of this chapter or a State program 
approved under part 281 of this chapter, or any underground oil storage 
tanks including below-grade vaulted tanks, deferred under 40 CFR part 
280, as originally promulgated, that supply emergency diesel generators 
at a nuclear power generation facility licensed by the Nuclear 
Regulatory Commission, provided that such a tank is subject to any 
Nuclear Regulatory Commission provision regarding design and quality 
criteria, including, but not limited to, 10 CFR part 50. Such emergency 
generator tanks must be marked on the facility diagram as provided in 
Sec. 112.7(a)(3), if the facility is otherwise subject to this part.
    (5) Any container with a storage capacity of less than 55 gallons of 
oil.
    (6) Any facility or part thereof used exclusively for wastewater 
treatment and not used to satisfy any requirement of this part. The 
production, recovery, or recycling of oil is not wastewater treatment 
for purposes of this paragraph.
    (7) Any ``motive power container,'' as defined in Sec. 112.2. The 
transfer of fuel or other oil into a motive power container at an 
otherwise regulated facility is not eligible for this exemption.
    (8) Hot-mix asphalt, or any hot-mix asphalt container.
    (9) Any container for heating oil used solely at a single-family 
residence.
    (10) Any pesticide application equipment or related mix containers.

diagram as provided in Sec. 112.7(a)(3), if the facility is otherwise 
subject to this part.
    (12) Any milk and milk product container and associated piping and 
appurtenances.
    (e) This part establishes requirements for the preparation and 
implementation of Spill Prevention, Control,

[[Page 25]]

and Countermeasure (SPCC) Plans. SPCC Plans are designed to complement 
existing laws, regulations, rules, standards, policies, and procedures 
pertaining to safety standards, fire prevention, and pollution 
prevention rules. The purpose of an SPCC Plan is to form a comprehensive 
Federal/State spill prevention program that minimizes the potential for 
discharges. The SPCC Plan must address all relevant spill prevention, 
control, and countermeasures necessary at the specific facility. 
Compliance with this part does not in any way relieve the owner or 
operator of an onshore or an offshore facility from compliance with 
other Federal, State, or local laws.
    (f) Notwithstanding paragraph (d) of this section, the Regional 
Administrator may require that the owner or operator of any facility 
subject to the jurisdiction of EPA under section 311(j) of the CWA 
prepare and implement an SPCC Plan, or any applicable part, to carry out 
the purposes of the CWA.
    (1) Following a preliminary determination, the Regional 
Administrator must provide a written notice to the owner or operator 
stating the reasons why he must prepare an SPCC Plan, or applicable 
part. The Regional Administrator must send such notice to the owner or 
operator by certified mail or by personal delivery. If the owner or 
operator is a corporation, the Regional Administrator must also mail a 
copy of such notice to the registered agent, if any and if known, of the 
corporation in the State where the facility is located.
    (2) Within 30 days of receipt of such written notice, the owner or 
operator may provide information and data and may consult with the 
Agency about the need to prepare an SPCC Plan, or applicable part.
    (3) Within 30 days following the time under paragraph (b)(2) of this 
section within which the owner or operator may provide information and 
data and consult with the Agency about the need to prepare an SPCC Plan, 
or applicable part, the Regional Administrator must make a final 
determination regarding whether the owner or operator is required to 
prepare and implement an SPCC Plan, or applicable part. The Regional 
Administrator must send the final determination to the owner or operator 
by certified mail or by personal delivery. If the owner or operator is a 
corporation, the Regional Administrator must also mail a copy of the 
final determination to the registered agent, if any and if known, of the 
corporation in the State where the facility is located.
    (4) If the Regional Administrator makes a final determination that 
an SPCC Plan, or applicable part, is necessary, the owner or operator 
must prepare the Plan, or applicable part, within six months of that 
final determination and implement the Plan, or applicable part, as soon 
as possible, but not later than one year after the Regional 
Administrator has made a final determination.
    (5) The owner or operator may appeal a final determination made by 
the Regional Administrator requiring preparation and implementation of 
an SPCC Plan, or applicable part, under this paragraph. The owner or 
operator must make the appeal to the Administrator of EPA within 30 days 
of receipt of the final determination under paragraph (b)(3) of this 
section from the Regional Administrator requiring preparation and/or 
implementation of an SPCC Plan, or applicable part. The owner or 
operator must send a complete copy of the appeal to the Regional 
Administrator at the time he makes the appeal to the Administrator. The 
appeal must contain a clear and concise statement of the issues and 
points of fact in the case. In the appeal, the owner or operator may 
also provide additional information. The additional information may be 
from any person. The Administrator may request additional information 
from the owner or operator. The Administrator must render a decision 
within 60 days of receiving the appeal or additional information 
submitted by the owner or operator and must serve the owner or operator 
with the decision made in the appeal in the manner described in 
paragraph (f)(1) of this section.

Sec. 112.2  Definitions.

    For the purposes of this part:

[[Page 26]]

    Adverse weather means weather conditions that make it difficult for 
response equipment and personnel to clean up or remove spilled oil, and 
that must be considered when identifying response systems and equipment 
in a response plan for the applicable operating environment. Factors to 
consider include significant wave height as specified in appendix E to 
this part (as appropriate), ice conditions, temperatures, weather-
related visibility, and currents within the area in which the systems or 
equipment is intended to function.
    Alteration means any work on a container involving cutting, burning, 
welding, or heating operations that changes the physical dimensions or 
configuration of the container.
    Animal fat means a non-petroleum oil, fat, or grease of animal, 
fish, or marine mammal origin.
    Breakout tank means a container used to relieve surges in an oil 
pipeline system or to receive and store oil transported by a pipeline 
for reinjection and continued transportation by pipeline.
    Bulk storage container means any container used to store oil. These 
containers are used for purposes including, but not limited to, the 
storage of oil prior to use, while being used, or prior to further 
distribution in commerce. Oil-filled electrical, operating, or 
manufacturing equipment is not a bulk storage container.
    Bunkered tank means a container constructed or placed in the ground 
by cutting the earth and re-covering the container in a manner that 
breaks the surrounding natural grade, or that lies above grade, and is 
covered with earth, sand, gravel, asphalt, or other material. A bunkered 
tank is considered an aboveground storage container for purposes of this 
part.
    Completely buried tank means any container completely below grade 
and covered with earth, sand, gravel, asphalt, or other material. 
Containers in vaults, bunkered tanks, or partially buried tanks are 
considered aboveground storage containers for purposes of this part.
    Complex means a facility possessing a combination of transportation-
related and non-transportation-related components that is subject to the 
jurisdiction of more than one Federal agency under section 311(j) of the 
CWA.
    Contiguous zone means the zone established by the United States 
under Article 24 of the Convention of the Territorial Sea and Contiguous 
Zone, that is contiguous to the territorial sea and that extends nine 
miles seaward from the outer limit of the territorial area.
    Contract or other approved means means:
    (1) A written contractual agreement with an oil spill removal 
organization that identifies and ensures the availability of the 
necessary personnel and equipment within appropriate response times; 
and/or
    (2) A written certification by the owner or operator that the 
necessary personnel and equipment resources, owned or operated by the 
facility owner or operator, are available to respond to a discharge 
within appropriate response times; and/or
    (3) Active membership in a local or regional oil spill removal 
organization that has identified and ensures adequate access through 
such membership to necessary personnel and equipment to respond to a 
discharge within appropriate response times in the specified geographic 
area; and/or
    (4) Any other specific arrangement approved by the Regional 
Administrator upon request of the owner or operator.
    Discharge includes, but is not limited to, any spilling, leaking, 
pumping, pouring, emitting, emptying, or dumping of oil, but excludes 
discharges in compliance with a permit under section 402 of the CWA; 
discharges resulting from circumstances identified, reviewed, and made a 
part of the public record with respect to a permit issued or modified 
under section 402 of the CWA, and subject to a condition in such permit; 
or continuous or anticipated intermittent discharges from a point 
source, identified in a permit or permit application under section 402 
of the CWA, that are caused by events occurring within the scope of 
relevant operating or treatment systems. For purposes of this part, the 
term discharge shall not include any discharge of oil that is authorized 
by a permit issued under section 13 of the River and Harbor Act of 1899 
(33 U.S.C. 407).

[[Page 27]]

    Facility means any mobile or fixed, onshore or offshore building, 
property, parcel, lease, structure, installation, equipment, pipe, or 
pipeline (other than a vessel or a public vessel) used in oil well 
drilling operations, oil production, oil refining, oil storage, oil 
gathering, oil processing, oil transfer, oil distribution, and oil waste 
treatment, or in which oil is used, as described in appendix A to this 
part. The boundaries of a facility depend on several site-specific 
factors, including but not limited to, the ownership or operation of 
buildings, structures, and equipment on the same site and types of 
activity at the site. Contiguous or non-contiguous buildings, 
properties, parcels, leases, structures, installations, pipes, or 
pipelines under the ownership or operation of the same person may be 
considered separate facilities. Only this definition governs whether a 
facility is subject to this part.
    Farm means a facility on a tract of land devoted to the production 
of crops or raising of animals, including fish, which produced and sold, 
or normally would have produced and sold, $1,000 or more of agricultural 
products during a year.
    Fish and wildlife and sensitive environments means areas that may be 
identified by their legal designation or by evaluations of Area 
Committees (for planning) or members of the Federal On-Scene 
Coordinator's spill response structure (during responses). These areas 
may include wetlands, National and State parks, critical habitats for 
endangered or threatened species, wilderness and natural resource areas, 
marine sanctuaries and estuarine reserves, conservation areas, 
preserves, wildlife areas, wildlife refuges, wild and scenic rivers, 
recreational areas, national forests, Federal and State lands that are 
research national areas, heritage program areas, land trust areas, and 
historical and archaeological sites and parks. These areas may also 
include unique habitats such as aquaculture sites and agricultural 
surface water intakes, bird nesting areas, critical biological resource 
areas, designated migratory routes, and designated seasonal habitats.
    Injury means a measurable adverse change, either long- or short-
term, in the chemical or physical quality or the viability of a natural 
resource resulting either directly or indirectly from exposure to a 
discharge, or exposure to a product of reactions resulting from a 
discharge.
    Loading/unloading rack means a fixed structure (such as a platform, 
gangway) necessary for loading or unloading a tank truck or tank car, 
which is located at a facility subject to the requirements of this part. 
A loading/unloading rack includes a loading or unloading arm, and may 
include any combination of the following: piping assemblages, valves, 
pumps, shut-off devices, overfill sensors, or personnel safety devices.
    Maximum extent practicable means within the limitations used to 
determine oil spill planning resources and response times for on-water 
recovery, shoreline protection, and cleanup for worst case discharges 
from onshore non-transportation-related facilities in adverse weather. 
It includes the planned capability to respond to a worst case discharge 
in adverse weather, as contained in a response plan that meets the 
requirements in Sec. 112.20 or in a specific plan approved by the 
Regional Administrator.
    Mobile refueler means a bulk storage container onboard a vehicle or 
towed, that is designed or used solely to store and transport fuel for 
transfer into or from an aircraft, motor vehicle, locomotive, vessel, 
ground service equipment, or other oil storage container.
    Motive power container means any onboard bulk storage container used 
primarily to power the movement of a motor vehicle, or ancillary onboard 
oil-filled operational equipment. An onboard bulk storage container 
which is used to store or transfer oil for further distribution is not a 
motive power container. The definition of motive power container does 
not include oil drilling or workover equipment, including rigs.
    Navigable waters means waters of the United States, including the 
territorial seas.
    (1) For purposes of the Clean Water Act, 33 U.S.C. 1251 et seq. and 
its implementing regulations, subject to the exclusions in paragraph (2) 
of this definition, the term ``waters of the United States'' means:

[[Page 28]]

    (i) All waters which are currently used, were used in the past, or 
may be susceptible to use in interstate or foreign commerce, including 
all waters which are subject to the ebb and flow of the tide;
    (ii) All interstate waters, including interstate wetlands;
    (iii) The territorial seas;
    (iv) All impoundments of waters otherwise identified as waters of 
the United States under this section;
    (v) All tributaries, as defined in paragraph (3)(iii) of this 
definition, of waters identified in paragraphs (1)(i) through (iii) of 
this definition;
    (vi) All waters adjacent to a water identified in paragraphs (1)(i) 
through (v) of this definition, including wetlands, ponds, lakes, 
oxbows, impoundments, and similar waters;
    (vii) All waters in paragraphs (1)(vii)(A) through (E) of this 
definition where they are determined, on a case-specific basis, to have 
a significant nexus to a water identified in paragraphs (1)(i) through 
(iii) of this definition. The waters identified in each of paragraphs 
(1)(vii)(A) through (E) of this definition are similarly situated and 
shall be combined, for purposes of a significant nexus analysis, in the 
watershed that drains to the nearest water identified in paragraphs 
(1)(i) through (iii) of this definition. Waters identified in this 
paragraph shall not be combined with waters identified in paragraph 
(1)(vi) of this section when performing a significant nexus analysis. If 
waters identified in this paragraph are also an adjacent water under 
paragraph (1)(vi), they are an adjacent water and no case-specific 
significant nexus analysis is required.
    (A) Prairie potholes. Prairie potholes are a complex of glacially 
formed wetlands, usually occurring in depressions that lack permanent 
natural outlets, located in the upper Midwest.
    (B) Carolina bays and Delmarva bays. Carolina bays and Delmarva bays 
are ponded, depressional wetlands that occur along the Atlantic coastal 
plain.
    (C) Pocosins. Pocosins are evergreen shrub and tree dominated 
wetlands found predominantly along the Central Atlantic coastal plain.
    (D) Western vernal pools. Western vernal pools are seasonal wetlands 
located in parts of California and associated with topographic 
depression, soils with poor drainage, mild, wet winters and hot, dry 
summers.
    (E) Texas coastal prairie wetlands. Texas coastal prairie wetlands 
are freshwater wetlands that occur as a mosaic of depressions, ridges, 
intermound flats, and mima mound wetlands located along the Texas Gulf 
Coast.
    (viii) All waters located within the 100-year floodplain of a water 
identified in paragraphs (1)(i) through (iii) of this definition and all 
waters located within 4,000 feet of the high tide line or ordinary high 
water mark of a water identified in paragraphs (1)(i) through (v) of 
this definition where they are determined on a case-specific basis to 
have a significant nexus to a water identified in paragraphs (1)(i) 
through (iii) of this definition. For waters determined to have a 
significant nexus, the entire water is a water of the United States if a 
portion is located within the 100-year floodplain of a water identified 
in paragraphs (1)(i) through (iii) of this definition or within 4,000 
feet of the high tide line or ordinary high water mark. Waters 
identified in this paragraph shall not be combined with waters 
identified in paragraph (1)(vi) of this definition when performing a 
significant nexus analysis. If waters identified in this paragraph are 
also an adjacent water under paragraph (1)(vi), they are an adjacent 
water and no case-specific significant nexus analysis is required.
    (2) The following are not ``waters of the United States'' even where 
they otherwise meet the terms of paragraphs (1)(iv) through (viii) of 
this definition.
    (i) The following ditches:
    (A) Ditches with ephemeral flow that are not a relocated tributary 
or excavated in a tributary.
    (B) Ditches with intermittent flow that are not a relocated 
tributary, excavated in a tributary, or drain wetlands.

as farm and stock watering ponds, irrigation ponds, settling basins, 
fields flooded for rice growing, log cleaning ponds, or cooling ponds;
    (C) Artificial reflecting pools or swimming pools created in dry 
land;
    (D) Small ornamental waters created in dry land;
    (E) Water-filled depressions created in dry land incidental to 
mining or construction activity, including pits excavated for obtaining 
fill, sand, or gravel that fill with water;
    (F) Erosional features, including gullies, rills, and other 
ephemeral features that do not meet the definition of tributary, non-
wetland swales, and lawfully constructed grassed waterways; and
    (G) Puddles.
    (iii) Groundwater, including groundwater drained through subsurface 
drainage systems.
    (iv) Stormwater control features constructed to convey, treat, or 
store stormwater that are created in dry land.
    (v) Wastewater recycling structures constructed in dry land; 
detention and retention basins built for wastewater recycling; 
groundwater recharge basins; percolation ponds built for wastewater 
recycling; and water distributary structures built for wastewater 
recycling.
    (3) In this definition, the following terms apply:
    (i) Adjacent. The term adjacent means bordering, contiguous, or 
neighboring a water identified in paragraphs (1)(i) through (v) of this 
definition, including waters separated by constructed dikes or barriers, 
natural river berms, beach dunes, and the like. For purposes of 
adjacency, an open water such as a pond or lake includes any wetlands 
within or abutting its ordinary high water mark. Adjacency is not 
limited to waters located laterally to a water identified in paragraphs 
(1)(i) through (v) of this definition. Adjacent waters also include all 
waters that connect segments of a water identified in paragraphs (1)(i) 
through (v) or are located at the head of a water identified in 
paragraphs (1)(i) through (v) of this definition and are bordering, 
contiguous, or neighboring such water. Waters being used for established 
normal farming, ranching, and silviculture activities (33 U.S.C. 
1344(f)) are not adjacent.
    (ii) Neighboring. The term neighboring means:
    (A) All waters located within 100 feet of the ordinary high water 
mark of a water identified in paragraphs (1)(i) through (v) of this 
definition. The entire water is neighboring if a portion is located 
within 100 feet of the ordinary high water mark;
    (B) All waters located within the 100-year floodplain of a water 
identified in paragraphs (1)(i) through (v) of this definition and not 
more than 1,500 feet from the ordinary high water mark of such water. 
The entire water is neighboring if a portion is located within 1,500 
feet of the ordinary high water mark and within the 100-year floodplain;
    (C) All waters located within 1,500 feet of the high tide line of a 
water identified in paragraphs (1)(i) or (1)(iii) of this definition, 
and all waters within 1,500 feet of the ordinary high water mark of the 
Great Lakes. The entire water is neighboring if a portion is located 
within 1,500 feet of the high tide line or within 1,500 feet of the 
ordinary high water mark of the Great Lakes.
    (iii) Tributary and tributaries. The terms tributary and tributaries 
each mean a water that contributes flow, either directly or through 
another water (including an impoundment identified in paragraph (1)(iv) 
of this definition), to a water identified in paragraphs (1)(i) through 
(iii) of this definition that is characterized by the presence of the 
physical indicators of a bed and banks and an ordinary high water mark. 
These physical indicators demonstrate there is volume, frequency, and 
duration of flow sufficient to create a bed and banks and an ordinary 
high water mark, and thus to qualify as a tributary. A tributary can be 
a natural, man-altered, or man-made water and includes waters such as 
rivers, streams, canals, and ditches not excluded under paragraph (2) of 
this definition. A water that otherwise

[[Page 30]]

qualifies as a tributary under this definition does not lose its status 
as a tributary if, for any length, there are one or more constructed 
breaks (such as bridges, culverts, pipes, or dams), or one or more 
natural breaks (such as wetlands along the run of a stream, debris 
piles, boulder fields, or a stream that flows underground) so long as a 
bed and banks and an ordinary high water mark can be identified upstream 
of the break. A water that otherwise qualifies as a tributary under this 
definition does not lose its status as a tributary if it contributes 
flow through a water of the United States that does not meet the 
definition of tributary or through a non-jurisdictional water to a water 
identified in paragraphs (1)(i) through (iii) of this definition.
    (iv) Wetlands. The term wetlands means those areas that are 
inundated or saturated by surface or groundwater at a frequency and 
duration sufficient to support, and that under normal circumstances do 
support, a prevalence of vegetation typically adapted for life in 
saturated soil conditions. Wetlands generally include swamps, marshes, 
bogs, and similar areas.
    (v) Significant nexus. The term significant nexus means that a 
water, including wetlands, either alone or in combination with other 
similarly situated waters in the region, significantly affects the 
chemical, physical, or biological integrity of a water identified in 
paragraphs (1)(i) through (iii) of this definition. The term ``in the 
region'' means the watershed that drains to the nearest water identified 
in paragraphs (1)(i) through (iii) of this definition. For an effect to 
be significant, it must be more than speculative or insubstantial. 
Waters are similarly situated when they function alike and are 
sufficiently close to function together in affecting downstream waters. 
For purposes of determining whether or not a water has a significant 
nexus, the water's effect on downstream (1)(i) through (iii) waters 
shall be assessed by evaluating the aquatic functions identified in 
paragraphs (3)(v)(A) through (I) of this definition. A water has a 
significant nexus when any single function or combination of functions 
performed by the water, alone or together with similarly situated waters 
in the region, contributes significantly to the chemical, physical, or 
biological integrity of the nearest water identified in paragraphs 
(1)(i) through (iii) of this section. Functions relevant to the 
significant nexus evaluation are the following:
    (A) Sediment trapping,
    (B) Nutrient recycling,
    (C) Pollutant trapping, transformation, filtering, and transport,
    (D) Retention and attenuation of flood waters,
    (E) Runoff storage,
    (F) Contribution of flow,
    (G) Export of organic matter,
    (H) Export of food resources, and
    (I) Provision of life cycle dependent aquatic habitat (such as 
foraging, feeding, nesting, breeding, spawning, or use as a nursery 
area) for species located in a water identified in paragraphs (1)(i) 
through (iii) of this definition.
    (vi) Ordinary high water mark. The term ordinary high water mark 
means that line on the shore established by the fluctuations of water 
and indicated by physical characteristics such as a clear, natural line 
impressed on the bank, shelving, changes in the character of soil, 
destruction of terrestrial vegetation, the presence of litter and 
debris, or other appropriate means that consider the characteristics of 
the surrounding areas.
    (vii) High tide line. The term high tide line means the line of 
intersection of the land with the water's surface at the maximum height 
reached by a rising tide. The high tide line may be determined, in the 
absence of actual data, by a line of oil or scum along shore objects, a 
more or less continuous deposit of fine shell or debris on the foreshore 
or berm, other physical markings or characteristics, vegetation lines, 
tidal gages, or other suitable means that delineate the general height 
reached by a rising tide. The line encompasses spring high tides and 
other high tides that occur with periodic frequency but does not include 
storm surges in which there is a departure from the normal or predicted 
reach of the tide due to the piling up of water against a coast by 
strong winds such as those accompanying a hurricane or other intense 
storm.

Sec. 112.3  Requirement to prepare and implement a Spill Prevention,
Control, and Countermeasure Plan.

    The owner or operator or an onshore or offshore facility subject to 
this section must prepare in writing and implement a Spill Prevention 
Control and Countermeasure Plan (hereafter ``SPCC Plan'' or ``Plan''),'' 
in accordance with Sec. 112.7 and any other applicable section of this 
part.
    (a)(1) Except as otherwise provided in this section, if your 
facility, or mobile or portable facility, was in operation on or before 
August 16, 2002, you must maintain your Plan, but must amend it, if 
necessary to ensure compliance with this part, and implement the amended 
Plan no later than November 10, 2011. If such a facility becomes 
operational after August 16, 2002, through November 10, 2011, and could 
reasonably be expected to have a discharge as described in Sec. 
112.1(b), you must prepare and implement a Plan on or before November 
10, 2011. If such a facility (excluding oil production facilities) 
becomes operational after November 10, 2011, and could reasonably be 
expected to have a discharge as described in Sec. 112.1(b), you must 
prepare and implement a Plan before you begin operations. You are not 
required to prepare a new Plan each time you move a mobile or portable 
facility to a new site; the Plan may be general. When you move the 
mobile or portable facility, you must locate and install it using the 
discharge prevention practices outlined in the Plan for the facility. 
The Plan is applicable only while the mobile or portable facility is in 
a fixed (non-transportation) operating mode.
    (2) If your drilling, production or workover facility, including a 
mobile or portable facility, is offshore or has an offshore component; 
or your onshore facility is required to have and submit a Facility 
Response Plan pursuant to 40 CFR 112.20(a), and was in operation on or 
before August 16, 2002, you must maintain your Plan, but

[[Page 33]]

must amend it, if necessary to ensure compliance with this part, and 
implement the amended Plan no later than November 10, 2010. If such a 
facility becomes operational after August 16, 2002, through November 10, 
2010, and could reasonably be expected to have a discharge as described 
in Sec. 112.1(b), you must prepare and implement a Plan on or before 
November 10, 2010. If such a facility (excluding oil production 
facilities) becomes operational after November 10, 2010, and could 
reasonably be expected to have a discharge as described in Sec. 
112.1(b), you must prepare and implement a Plan before you begin 
operations. You are not required to prepare a new Plan each time you 
move a mobile or portable facility to a new site; the Plan may be 
general. When you move the mobile or portable facility, you must locate 
and install it using the discharge prevention practices outlined in the 
Plan for the facility. The Plan is applicable only while the mobile or 
portable facility is in a fixed (non-transportation) operating mode.
    (3) If your farm, as defined in Sec. 112.2, was in operation on or 
before August 16, 2002, you must maintain your Plan, but must amend it, 
if necessary to ensure compliance with this part, and implement the 
amended Plan on or before May 10, 2013. If your farm becomes operational 
after August 16, 2002, through May 10, 2013, and could reasonably be 
expected to have a discharge as described in Sec. 112.1(b), you must 
prepare and implement a Plan on or before May 10, 2013. If your farm 
becomes operational after May 10, 2013, and could reasonably be expected 
to have a discharge as described in Sec. 112.1(b), you must prepare and 
implement a Plan before you begin operations.
    (b) If your oil production facility as described in paragraph (a)(1) 
of this section becomes operational after November 10, 2011, or as 
described in paragraph (a)(2) of this section becomes operational after 
November 10, 2010, and could reasonably be expected to have a discharge 
as described in Sec. 112.1(b), you must prepare and implement a Plan 
within six months after you begin operations.
    (c) [Reserved]
    (d) Except as provided in Sec. 112.6, a licensed Professional 
Engineer must review and certify a Plan for it to be effective to 
satisfy the requirements of this part.
    (1) By means of this certification the Professional Engineer 
attests:
    (i) That he is familiar with the requirements of this part ;
    (ii) That he or his agent has visited and examined the facility;
    (iii) That the Plan has been prepared in accordance with good 
engineering practice, including consideration of applicable industry 
standards, and with the requirements of this part;
    (iv) That procedures for required inspections and testing have been 
established; and
    (v) That the Plan is adequate for the facility.
    (vi) That, if applicable, for a produced water container subject to 
Sec. 112.9(c)(6), any procedure to minimize the amount of free-phase 
oil is designed to reduce the accumulation of free-phase oil and the 
procedures and frequency for required inspections, maintenance and 
testing have been established and are described in the Plan.
    (2) Such certification shall in no way relieve the owner or operator 
of a facility of his duty to prepare and fully implement such Plan in 
accordance with the requirements of this part.
    (e) If you are the owner or operator of a facility for which a Plan 
is required under this section, you must:
    (1) Maintain a complete copy of the Plan at the facility if the 
facility is normally attended at least four hours per day, or at the 
nearest field office if the facility is not so attended, and
    (2) Have the Plan available to the Regional Administrator for on-
site review during normal working hours.
    (f) Extension of time. (1) The Regional Administrator may authorize 
an extension of time for the preparation and full implementation of a 
Plan, or any amendment thereto, beyond the time permitted for the 
preparation, implementation, or amendment of a Plan under this part, 
when he finds that the owner or operator of a facility subject to this 
section, cannot fully comply with the requirements as a result of either 
nonavailability of qualified personnel, or delays in construction or

[[Page 34]]

equipment delivery beyond the control and without the fault of such 
owner or operator or his agents or employees.
    (2) If you are an owner or operator seeking an extension of time 
under paragraph (f)(1) of this section, you may submit a written 
extension request to the Regional Administrator. Your request must 
include:
    (i) A full explanation of the cause for any such delay and the 
specific aspects of the Plan affected by the delay;
    (ii) A full discussion of actions being taken or contemplated to 
minimize or mitigate such delay; and
    (iii) A proposed time schedule for the implementation of any 
corrective actions being taken or contemplated, including interim dates 
for completion of tests or studies, installation and operation of any 
necessary equipment, or other preventive measures. In addition you may 
present additional oral or written statements in support of your 
extension request.
    (3) The submission of a written extension request under paragraph 
(f)(2) of this section does not relieve you of your obligation to comply 
with the requirements of this part. The Regional Administrator may 
request a copy of your Plan to evaluate the extension request. When the 
Regional Administrator authorizes an extension of time for particular 
equipment or other specific aspects of the Plan, such extension does not 
affect your obligation to comply with the requirements related to other 
equipment or other specific aspects of the Plan for which the Regional 
Administrator has not expressly authorized an extension.
    (g) Qualified Facilities. The owner or operator of a qualified 
facility as defined in this subparagraph may self-certify his facility's 
Plan, as provided in Sec. 112.6. A qualified facility is one that meets 
the following Tier I or Tier II qualified facility criteria:
    (1) A Tier I qualified facility meets the qualification criteria in 
paragraph (g)(2) of this section and has no individual aboveground oil 
storage container with a capacity greater than 5,000 U.S. gallons.
    (2) A Tier II qualified facility is one that has had no single 
discharge as described in Sec. 112.1(b) exceeding 1,000 U.S. gallons or 
no two discharges as described in Sec. 112.1(b) each exceeding 42 U.S. 
gallons within any twelve month period in the three years prior to the 
SPCC Plan self-certification date, or since becoming subject to this 
part if the facility has been in operation for less than three years 
(other than discharges as described in Sec. 112.1(b) that are the 
result of natural disasters, acts of war, or terrorism), and has an 
aggregate aboveground oil storage capacity of 10,000 U.S. gallons or 
less.

Sec. 112.4  Amendment of Spill Prevention, Control, and Countermeasure
Plan by Regional Administrator.

    If you are the owner or operator of a facility subject to this part, 
you must:
    (a) Notwithstanding compliance with Sec. 112.3, whenever your 
facility has discharged more than 1,000 U.S. gallons of oil in a single 
discharge as described in Sec. 112.1(b), or discharged more than 42 
U.S. gallons of oil in each of two discharges as described in Sec. 
112.1(b), occurring within any twelve month period, submit the following 
information to the Regional Administrator within 60 days from the time 
the facility becomes subject to this section:
    (1) Name of the facility;
    (2) Your name;
    (3) Location of the facility;
    (4) Maximum storage or handling capacity of the facility and normal 
daily throughput;

a description of equipment repairs and replacements;
    (6) An adequate description of the facility, including maps, flow 
diagrams, and topographical maps, as necessary;
    (7) The cause of such discharge as described in Sec. 112.1(b), 
including a failure analysis of the system or subsystem in which the 
failure occurred;
    (8) Additional preventive measures you have taken or contemplated to 
minimize the possibility of recurrence; and

[[Page 35]]

    (9) Such other information as the Regional Administrator may 
reasonably require pertinent to the Plan or discharge.
    (b) Take no action under this section until it applies to your 
facility. This section does not apply until the expiration of the time 
permitted for the initial preparation and implementation of the Plan 
under Sec. 112.3, but not including any amendments to the Plan.
    (c) Send to the appropriate agency or agencies in charge of oil 
pollution control activities in the State in which the facility is 
located a complete copy of all information you provided to the Regional 
Administrator under paragraph (a) of this section. Upon receipt of the 
information such State agency or agencies may conduct a review and make 
recommendations to the Regional Administrator as to further procedures, 
methods, equipment, and other requirements necessary to prevent and to 
contain discharges from your facility.
    (d) Amend your Plan, if after review by the Regional Administrator 
of the information you submit under paragraph (a) of this section, or 
submission of information to EPA by the State agency under paragraph (c) 
of this section, or after on-site review of your Plan, the Regional 
Administrator requires that you do so. The Regional Administrator may 
require you to amend your Plan if he finds that it does not meet the 
requirements of this part or that amendment is necessary to prevent and 
contain discharges from your facility.
    (e) Act in accordance with this paragraph when the Regional 
Administrator proposes by certified mail or by personal delivery that 
you amend your SPCC Plan. If the owner or operator is a corporation, he 
must also notify by mail the registered agent of such corporation, if 
any and if known, in the State in which the facility is located. The 
Regional Administrator must specify the terms of such proposed 
amendment. Within 30 days from receipt of such notice, you may submit 
written information, views, and arguments on the proposed amendment. 
After considering all relevant material presented, the Regional 
Administrator must either notify you of any amendment required or 
rescind the notice. You must amend your Plan as required within 30 days 
after such notice, unless the Regional Administrator, for good cause, 
specifies another effective date. You must implement the amended Plan as 
soon as possible, but not later than six months after you amend your 
Plan, unless the Regional Administrator specifies another date.
    (f) If you appeal a decision made by the Regional Administrator 
requiring an amendment to an SPCC Plan, send the appeal to the EPA 
Administrator in writing within 30 days of receipt of the notice from 
the Regional Administrator requiring the amendment under paragraph (e) 
of this section. You must send a complete copy of the appeal to the 
Regional Administrator at the time you make the appeal. The appeal must 
contain a clear and concise statement of the issues and points of fact 
in the case. It may also contain additional information from you, or 
from any other person. The EPA Administrator may request additional 
information from you, or from any other person. The EPA Administrator 
must render a decision within 60 days of receiving the appeal and must 
notify you of his decision.



Sec. 112.5  Amendment of Spill Prevention, Control, and Countermeasure
Plan by owners or operators.

    If you are the owner or operator of a facility subject to this part, 
you must:
    (a) Amend the SPCC Plan for your facility in accordance with the 
general requirements in Sec. 112.7, and with any specific section of 
this part applicable to your facility, when there is a change in the 
facility design, construction, operation, or maintenance that materially 
affects its potential for a discharge as described in Sec. 112.1(b). 
Examples of changes that may require amendment of the Plan include, but 
are not limited to: commissioning or decommissioning containers; 
replacement, reconstruction, or movement of containers; reconstruction, 
replacement, or installation of piping systems; construction or 
demolition that might alter secondary containment structures; changes of 
product or service; or revision of standard operation or maintenance 
procedures at a facility. An amendment made under this section

[[Page 36]]

must be prepared within six months, and implemented as soon as possible, 
but not later than six months following preparation of the amendment.
    (b) Notwithstanding compliance with paragraph (a) of this section, 
complete a review and evaluation of the SPCC Plan at least once every 
five years from the date your facility becomes subject to this part; or, 
if your facility was in operation on or before August 16, 2002, five 
years from the date your last review was required under this part. As a 
result of this review and evaluation, you must amend your SPCC Plan 
within six months of the review to include more effective prevention and 
control technology if the technology has been field-proven at the time 
of the review and will significantly reduce the likelihood of a 
discharge as described in Sec. 112.1(b) from the facility. You must 
implement any amendment as soon as possible, but not later than six 
months following preparation of any amendment. You must document your 
completion of the review and evaluation, and must sign a statement as to 
whether you will amend the Plan, either at the beginning or end of the 
Plan or in a log or an appendix to the Plan. The following words will 
suffice, ``I have completed review and evaluation of the SPCC Plan for 
(name of facility) on (date), and will (will not) amend the Plan as a 
result.''
    (c) Except as provided in Sec. 112.6, have a Professional Engineer 
certify any technical amendments to your Plan in accordance with Sec. 
112.3(d).

mobile refuelers and other non-transportation-related tank trucks), 
including mobile or portable oil storage containers, so that you provide 
a secondary means of containment for the entire capacity of the largest 
single container plus additional capacity to contain precipitation. 
Dikes, containment curbs, and pits are commonly employed for this 
purpose. You may also use an alternative system consisting of a drainage 
trench enclosure that must be arranged so that any discharge will 
terminate and be safely confined in a catchment basin or holding pond. 
Position or locate mobile or portable oil storage containers to prevent 
a discharge as described in Sec. 112.1(b).
    (iii) Overfill prevention, in lieu of the requirements in Sec. Sec. 
112.8(c)(8) and 112.12(c)(8). Ensure that each container is provided 
with a system or documented procedure to prevent overfills of the 
container, describe the system or procedure in the SPCC Plan and 
regularly test to ensure proper operation or efficacy.
    (b) Tier II Qualified Facilities--(1) Preparation and Self-
Certification of Plan. If you are the owner or operator of a facility 
that meets the Tier II qualified facility criteria in Sec. 112.3(g)(2), 
you may choose to self-certify your Plan. You must certify in the Plan 
that:
    (i) You are familiar with the requirements of this part;

produced water containers and any associated piping, except as provided 
in paragraph (b)(3) of this section; and
    (viii) The Plan and individual(s) responsible for implementing the 
Plan have the full approval of management and the facility owner or 
operator has committed the necessary resources to fully implement the 
Plan.
    (2) Technical Amendments. If you self-certify your Plan pursuant to 
paragraph (b)(1) of this section, you must certify any technical 
amendments to your Plan in accordance with paragraph (b)(1) of this 
section when there is a change in the facility design, construction, 
operation, or maintenance that affects its potential for a discharge as 
described in Sec. 112.1(b), except:
    (i) If a Professional Engineer certified a portion of your Plan in 
accordance with paragraph (b)(4) of this section, and the technical 
amendment affects this portion of the Plan, you must have the amended 
provisions of your Plan certified by a Professional Engineer in 
accordance with paragraph (b)(4)(ii) of this section.
    (ii) If the change is such that the facility no longer meets the 
Tier II qualifying criteria in Sec. 112.3(g)(2) because it exceeds 
10,000 U.S. gallons in aggregate aboveground storage capacity you must, 
within six months following the change, prepare and implement a Plan in 
accordance with the general Plan requirements in Sec. 112.7 and the 
applicable requirements in subparts B and C of this part, including 
having the Plan certified by a Professional Engineer as required under 
Sec. 112.3(d).
    (3) Applicable Requirements. Except as provided in this paragraph, 
your self-certified SPCC Plan must comply with Sec. 112.7 and the 
applicable requirements in subparts B and C of this part:
    (i) Environmental Equivalence. Your Plan may not include alternate

Sec. 112.7  General requirements for Spill Prevention, Control,
and Countermeasure Plans.

    If you are the owner or operator of a facility subject to this part 
you must prepare a Plan in accordance with good engineering practices. 
The Plan must have the full approval of management at a level of 
authority to commit the necessary resources to fully implement the Plan. 
You must prepare the Plan in writing. If you do not follow the sequence 
specified in this section for the Plan, you must prepare an equivalent 
Plan acceptable to the Regional Administrator that meets all of the 
applicable requirements listed in this part, and you must supplement it 
with a section cross-referencing the location of requirements listed in 
this part and the equivalent requirements in the other prevention plan. 
If the Plan calls for additional facilities or procedures, methods, or 
equipment not yet fully operational, you must discuss these items in 
separate paragraphs, and must explain separately the details of 
installation and operational start-up. As detailed elsewhere in this 
section, you must also:
    (a)(1) Include a discussion of your facility's conformance with the 
requirements listed in this part.
    (2) Comply with all applicable requirements listed in this part. 
Except as provided in Sec. 112.6, your Plan may deviate from the 
requirements in paragraphs (g), (h)(2) and (3), and (i) of this section 
and the requirements in subparts B and C of this part, except the 
secondary containment requirements in paragraphs (c) and (h)(1) of this 
section, and Sec. Sec. 112.8(c)(2), 112.8(c)(11), 112.9(c)(2), 
112.9(d)(3), 112.10(c), 112.12(c)(2), and 112.12(c)(11), where 
applicable to a specific facility, if you provide equivalent 
environmental protection by some other means of spill prevention, 
control, or countermeasure. Where your Plan does not conform to the 
applicable requirements in paragraphs (g), (h)(2) and (3), and (i) of 
this section, or the requirements of subparts B and C of this part, 
except the secondary containment requirements in paragraph (c) and 
(h)(1) of this section, and Sec. Sec. 112.8(c)(2), 112.8(c)(11), 
112.9(c)(2), 112.10(c), 112.12(c)(2), and 112.12(c)(11), you must state 
the reasons for nonconformance in your Plan and describe in detail 
alternate methods and how you will achieve equivalent environmental 
protection. If the Regional Administrator determines that the measures 
described in your Plan do not provide equivalent environmental 
protection, he may require that you amend your Plan, following the 
procedures in Sec. 112.4(d) and (e).
    (3) Describe in your Plan the physical layout of the facility and 
include a facility diagram, which must mark the location and contents of 
each fixed oil storage container and the storage area where mobile or 
portable containers are located. The facility diagram must identify the 
location of and mark as ``exempt'' underground tanks that are otherwise 
exempted from the requirements of this part under Sec. 112.1(d)(4). The 
facility diagram must also include all transfer stations and connecting 
pipes, including intra-facility gathering lines that are otherwise 
exempted from the requirements of this part under Sec. 112.1(d)(11). 
You must also address in your Plan:
    (i) The type of oil in each fixed container and its storage 
capacity. For mobile or portable containers, either

[[Page 40]]

provide the type of oil and storage capacity for each container or 
provide an estimate of the potential number of mobile or portable 
containers, the types of oil, and anticipated storage capacities;
    (ii) Discharge prevention measures including procedures for routine 
handling of products (loading, unloading, and facility transfers, etc.);
    (iii) Discharge or drainage controls such as secondary containment 
around containers and other structures, equipment, and procedures for 
the control of a discharge;
    (iv) Countermeasures for discharge discovery, response, and cleanup 
(both the facility's capability and those that might be required of a 
contractor);
    (v) Methods of disposal of recovered materials in accordance with 
applicable legal requirements; and
    (vi) Contact list and phone numbers for the facility response 
coordinator, National Response Center, cleanup contractors with whom you 
have an agreement for response, and all appropriate Federal, State, and 
local agencies who must be contacted in case of a discharge as described 
in Sec. 112.1(b).
    (4) Unless you have submitted a response plan under Sec. 112.20, 
provide information and procedures in your Plan to enable a person 
reporting a discharge as described in Sec. 112.1(b) to relate 
information on the exact address or location and phone number of the 
facility; the date and time of the discharge, the type of material 
discharged; estimates of the total quantity discharged; estimates of the 
quantity discharged as described in Sec. 112.1(b); the source of the 
discharge; a description of all affected media; the cause of the 
discharge; any damages or injuries caused by the discharge; actions 
being used to stop, remove, and mitigate the effects of the discharge; 
whether an evacuation may be needed; and, the names of individuals and/
or organizations who have also been contacted.
    (5) Unless you have submitted a response plan under Sec. 112.20, 
organize portions of the Plan describing procedures you will use when a 
discharge occurs in a way that will make them readily usable in an 
emergency, and include appropriate supporting material as appendices.
    (b) Where experience indicates a reasonable potential for equipment 
failure (such as loading or unloading equipment, tank overflow, rupture, 
or leakage, or any other equipment known to be a source of a discharge), 
include in your Plan a prediction of the direction, rate of flow, and 
total quantity of oil which could be discharged from the facility as a 
result of each type of major equipment failure.
    (c) Provide appropriate containment and/or diversionary structures 
or equipment to prevent a discharge as described in Sec. 112.1(b), 
except as provided in paragraph (k) of this section for qualified oil-
filled operational equipment, and except as provided in Sec. 
112.9(d)(3) for flowlines and intra-facility gathering lines at an oil 
production facility. The entire containment system, including walls and 
floor, must be capable of containing oil and must be constructed so that 
any discharge from a primary containment system, such as a tank, will 
not escape the containment system before cleanup occurs. In determining 
the method, design, and capacity for secondary containment, you need 
only to address the typical failure mode, and the most likely quantity 
of oil that would be discharged. Secondary containment may be either 
active or passive in design. At a minimum, you must use one of the 
following prevention systems or its equivalent:
    (1) For onshore facilities:
    (i) Dikes, berms, or retaining walls sufficiently impervious to 
contain oil;
    (ii) Curbing or drip pans;
    (iii) Sumps and collection systems;
    (iv) Culverting, gutters, or other drainage systems;
    (v) Weirs, booms, or other barriers;
    (vi) Spill diversion ponds;
    (vii) Retention ponds; or
    (viii) Sorbent materials.
    (2) For offshore facilities:
    (i) Curbing or drip pans; or
    (ii) Sumps and collection systems.
    (d) Provided your Plan is certified by a licensed Professional 
Engineer under Sec. 112.3(d), or, in the case of a qualified facility 
that meets the criteria in Sec. 112.3(g), the relevant sections of your

[[Page 41]]

Plan are certified by a licensed Professional Engineer under Sec. 
112.6(d), if you determine that the installation of any of the 
structures or pieces of equipment listed in paragraphs (c) and (h)(1) of 
this section, and Sec. Sec. 112.8(c)(2), 112.8(c)(11), 112.9(c)(2), 
112.10(c), 112.12(c)(2), and 112.12(c)(11) to prevent a discharge as 
described in Sec. 112.1(b) from any onshore or offshore facility is not 
practicable, you must clearly explain in your Plan why such measures are 
not practicable; for bulk storage containers, conduct both periodic 
integrity testing of the containers and periodic integrity and leak 
testing of the valves and piping; and, unless you have submitted a 
response plan under Sec. 112.20, provide in your Plan the following:
    (1) An oil spill contingency plan following the provisions of part 
109 of this chapter.
    (2) A written commitment of manpower, equipment, and materials 
required to expeditiously control and remove any quantity of oil 
discharged that may be harmful.
    (e) Inspections, tests, and records. Conduct inspections and tests 
required by this part in accordance with written procedures that you or 
the certifying engineer develop for the facility. You must keep these 
written procedures and a record of the inspections and tests, signed by 
the appropriate supervisor or inspector, with the SPCC Plan for a period 
of three years. Records of inspections and tests kept under usual and 
customary business practices will suffice for purposes of this 
paragraph.
    (f) Personnel, training, and discharge prevention procedures. (1) At 
a minimum, train your oil-handling personnel in the operation and 
maintenance of equipment to prevent discharges; discharge procedure 
protocols; applicable pollution control laws, rules, and regulations; 
general facility operations; and, the contents of the facility SPCC 
Plan.
    (2) Designate a person at each applicable facility who is 
accountable for discharge prevention and who reports to facility 
management.
    (3) Schedule and conduct discharge prevention briefings for your 
oil-handling personnel at least once a year to assure adequate 
understanding of the SPCC Plan for that facility. Such briefings must 
highlight and describe known discharges as described in Sec. 112.1(b) 
or failures, malfunctioning components, and any recently developed 
precautionary measures.
    (g) Security (excluding oil production facilities). Describe in your 
Plan how you secure and control access to the oil handling, processing 
and storage areas; secure master flow and drain valves; prevent 
unauthorized access to starter controls on oil pumps; secure out-of-
service and loading/unloading connections of oil pipelines; and address 
the appropriateness of security lighting to both prevent acts of 
vandalism and assist in the discovery of oil discharges.
    (h) Facility tank car and tank truck loading/unloading rack 
(excluding offshore facilities).
    (1) Where loading/unloading rack drainage does not flow into a 
catchment basin or treatment facility designed to handle discharges, use 
a quick drainage system for tank car or tank truck loading/unloading 
racks. You must design any containment system to hold at least the 
maximum capacity of any single compartment of a tank car or tank truck 
loaded or unloaded at the facility.
    (2) Provide an interlocked warning light or physical barrier system, 
warning signs, wheel chocks or vehicle brake interlock system in the 
area adjacent to a loading/unloading rack, to prevent vehicles from 
departing before complete disconnection of flexible or fixed oil 
transfer lines.
    (3) Prior to filling and departure of any tank car or tank truck, 
closely inspect for discharges the lowermost drain and all outlets of 
such vehicles, and if necessary, ensure that they are tightened, 
adjusted, or replaced to prevent liquid discharge while in transit.
    (i) If a field-constructed aboveground container undergoes a repair, 
alteration, reconstruction, or a change in service that might affect the 
risk of a discharge or failure due to brittle fracture or other 
catastrophe, or has discharged oil or failed due to brittle fracture 
failure or other catastrophe, evaluate the container for risk of 
discharge or failure due to brittle fracture or other catastrophe, and 
as necessary, take appropriate action.

[[Page 42]]

    (j) In addition to the minimal prevention standards listed under 
this section, include in your Plan a complete discussion of conformance 
with the applicable requirements and other effective discharge 
prevention and containment procedures listed in this part or any 
applicable more stringent State rules, regulations, and guidelines.
    (k) Qualified Oil-filled Operational Equipment. The owner or 
operator of a facility with oil-filled operational equipment that meets 
the qualification criteria in paragraph (k)(1) of this sub-section may 
choose to implement for this qualified oil-filled operational equipment 
the alternate requirements as described in paragraph (k)(2) of this sub-
section in lieu of general secondary containment required in paragraph 
(c) of this section.
    (1) Qualification Criteria--Reportable Discharge History: The owner 
or operator of a facility that has had no single discharge as described 
in Sec. 112.1(b) from any oil-filled operational equipment exceeding 
1,000 U.S. gallons or no two discharges as described in Sec. 112.1(b) 
from any oil-filled operational equipment each exceeding 42 U.S. gallons

areas by valves to prevent a discharge into the drainage system or 
facility effluent treatment system, except where facility systems are 
designed to control such discharge. You may empty diked areas by pumps 
or ejectors; however, you must manually activate these pumps or ejectors 
and must inspect the condition of the accumulation before starting, to 
ensure no oil will be discharged.
    (2) Use valves of manual, open-and-closed design, for the drainage 
of diked areas. You may not use flapper-type drain valves to drain diked 
areas. If your facility drainage drains directly into a watercourse and 
not into an on-site wastewater treatment plant, you must inspect and may 
drain uncontaminated retained stormwater, as provided in paragraphs 
(c)(3)(ii), (iii), and (iv) of this section.
    (3) Design facility drainage systems from undiked areas with a 
potential for

[[Page 43]]

a discharge (such as where piping is located outside containment walls 
or where tank truck discharges may occur outside the loading area) to 
flow into ponds, lagoons, or catchment basins designed to retain oil or 
return it to the facility. You must not locate catchment basins in areas 
subject to periodic flooding.
    (4) If facility drainage is not engineered as in paragraph (b)(3) of 
this section, equip the final discharge of all ditches inside the 
facility with a diversion system that would, in the event of an 
uncontrolled discharge, retain oil in the facility.
    (5) Where drainage waters are treated in more than one treatment 
unit and such treatment is continuous, and pump transfer is needed, 
provide two ``lift'' pumps and permanently install at least one of the 
pumps. Whatever techniques you use, you must engineer facility drainage 
systems to prevent a discharge as described in Sec. 112.1(b) in case 
there is an equipment failure or human error at the facility.
    (c) Bulk storage containers. (1) Not use a container for the storage 
of oil unless its material and construction are compatible with the 
material stored and conditions of storage such as pressure and 
temperature.
    (2) Construct all bulk storage tank installations (except mobile 
refuelers and other non-transportation-related tank trucks) so that you 
provide a secondary means of containment for the entire capacity of the 
largest single container and sufficient freeboard to contain 
precipitation. You must ensure that diked areas are sufficiently 
impervious to contain discharged oil. Dikes, containment curbs, and pits 
are commonly employed for this purpose. You may also use an alternative 
system consisting of a drainage trench enclosure that must be arranged 
so that any discharge will terminate and be safely confined in a 
facility catchment basin or holding pond.
    (3) Not allow drainage of uncontaminated rainwater from the diked 
area into a storm drain or discharge of an effluent into an open 
watercourse, lake, or pond, bypassing the facility treatment system 
unless you:
    (i) Normally keep the bypass valve sealed closed.
    (ii) Inspect the retained rainwater to ensure that its presence will 
not cause a discharge as described in Sec. 112.1(b).
    (iii) Open the bypass valve and reseal it following drainage under 
responsible supervision; and
    (iv) Keep adequate records of such events, for example, any records 
required under permits issued in accordance with Sec. Sec. 122.41(j)(2) 
and 122.41(m)(3) of this chapter.
    (4) Protect any completely buried metallic storage tank installed on 
or after January 10, 1974 from corrosion by coatings or cathodic 
protection compatible with local soil conditions. You must regularly 
leak test such completely buried metallic storage tanks.
    (5) Not use partially buried or bunkered metallic tanks for the 
storage of oil, unless you protect the buried section of the tank from 
corrosion. You must protect partially buried and bunkered tanks from 
corrosion by coatings or cathodic protection compatible with local soil 
conditions.
    (6) Test or inspect each aboveground container for integrity on a 
regular schedule and whenever you make material repairs. You must 
determine, in accordance with industry standards, the appropriate 
qualifications for personnel performing tests and inspections, the 
frequency and type of testing and inspections, which take into account 
container size, configuration, and design (such as containers that are: 
shop-built, field-erected, skid-mounted, elevated, equipped with a 
liner, double-walled, or partially buried). Examples of these integrity 
tests include, but are not limited to: visual inspection, hydrostatic 
testing, radiographic testing, ultrasonic testing, acoustic emissions 
testing, or other systems of non-destructive testing. You must keep 
comparison records and you must also inspect the container's supports 
and foundations. In addition, you must frequently inspect the outside of 
the container for signs of deterioration, discharges, or accumulation of 
oil inside diked areas. Records of inspections and tests kept under 
usual and customary business practices satisfy the recordkeeping 
requirements of this paragraph.

[[Page 44]]

    (7) Control leakage through defective internal heating coils by 
monitoring the steam return and exhaust lines for contamination from 
internal heating coils that discharge into an open watercourse, or pass 
the steam return or exhaust lines through a settling tank, skimmer, or 
other separation or retention system.
    (8) Engineer or update each container installation in accordance 
with good engineering practice to avoid discharges. You must provide at 
least one of the following devices:
    (i) High liquid level alarms with an audible or visual signal at a 
constantly attended operation or surveillance station. In smaller 
facilities an audible air vent may suffice.
    (ii) High liquid level pump cutoff devices set to stop flow at a 
predetermined container content level.
    (iii) Direct audible or code signal communication between the 
container gauger and the pumping station.
    (iv) A fast response system for determining the liquid level of each 
bulk storage container such as digital computers, telepulse, or direct 
vision gauges. If you use this alternative, a person must be present to 
monitor gauges and the overall filling of bulk storage containers.
    (v) You must regularly test liquid level sensing devices to ensure 
proper operation.
    (9) Observe effluent treatment facilities frequently enough to 
detect possible system upsets that could cause a discharge as described 
in Sec. 112.1(b).
    (10) Promptly correct visible discharges which result in a loss of 
oil from the container, including but not limited to seams, gaskets, 
piping, pumps, valves, rivets, and bolts. You must promptly remove any 
accumulations of oil in diked areas.
    (11) Position or locate mobile or portable oil storage containers to 
prevent a discharge as described in Sec. 112.1(b). Except for mobile 
refuelers and other non-transportation-related tank trucks, you must 
furnish a secondary means of containment, such as a dike or catchment 
basin, sufficient to contain the capacity of the largest single 
compartment or container with sufficient freeboard to contain 
precipitation.
    (d) Facility transfer operations, pumping, and facility process. (1) 
Provide buried piping that is installed or replaced on or after August 
16, 2002, with a protective wrapping and coating. You must also 
cathodically protect such buried piping installations or otherwise 
satisfy the corrosion protection standards for piping in part 280 of 
this chapter or a State program approved under part 281 of this chapter. 
If a section of buried line is exposed for any reason, you must 
carefully inspect it for deterioration. If you find corrosion damage, 
you must undertake additional examination and corrective action as 
indicated by the magnitude of the damage.
    (2) Cap or blank-flange the terminal connection at the transfer 
point and mark it as to origin when piping is not in service or is in 
standby service for an extended time.
    (3) Properly design pipe supports to minimize abrasion and corrosion 
and allow for expansion and contraction.
    (4) Regularly inspect all aboveground valves, piping, and 
appurtenances. During the inspection you must assess the general 
condition of items, such as flange joints, expansion joints, valve 
glands and bodies, catch pans, pipeline supports, locking of valves, and 
metal surfaces. You must also conduct integrity and leak testing of 
buried piping at the time of installation, modification, construction, 
relocation, or replacement.
    (5) Warn all vehicles entering the facility to be sure that no 
vehicle will endanger aboveground piping or other oil transfer 
operations.

subpart comply with Sec. 112.9(c)(2) and (c)(3).
    (d) Facility transfer operations, oil production facility. (1) 
Periodically and upon a regular schedule inspect all aboveground valves 
and piping associated with transfer operations for the general condition 
of flange joints, valve glands and bodies, drip pans, pipe supports, 
pumping well polish rod stuffing boxes, bleeder and gauge valves, and 
other such items.
    (2) Inspect saltwater (oil field brine) disposal facilities often, 
particularly following a sudden change in atmospheric temperature, to 
detect possible system upsets capable of causing a discharge.
    (3) For flowlines and intra-facility gathering lines that are not 
provided with secondary containment in accordance with Sec. 112.7(c),

Sec. 112.10  Spill Prevention, Control, and Countermeasure Plan 
requirements for onshore oil drilling and workover facilities.

    If you are the owner or operator of an onshore oil drilling and 
workover facility, you must:
    (a) Meet the general requirements listed under Sec. 112.7, and also 
meet the specific discharge prevention and containment procedures listed 
under this section.
    (b) Position or locate mobile drilling or workover equipment so as 
to prevent a discharge as described in Sec. 112.1(b).
    (c) Provide catchment basins or diversion structures to intercept 
and contain discharges of fuel, crude oil, or oily drilling fluids.
    (d) Install a blowout prevention (BOP) assembly and well control 
system before drilling below any casing string or during workover 
operations. The BOP assembly and well control system must be capable of 
controlling any well-head pressure that may be encountered while that 
BOP assembly and well control system are on the well.



Sec. 112.11  Spill Prevention, Control, and Countermeasure Plan 
requirements for offshore oil drilling, production, or workover
facilities.

    If you are the owner or operator of an offshore oil drilling, 
production, or workover facility, you must:
    (a) Meet the general requirements listed under Sec. 112.7, and also 
meet the specific discharge prevention and containment procedures listed 
under this section.
    (b) Use oil drainage collection equipment to prevent and control 
small oil discharges around pumps, glands, valves, flanges, expansion 
joints, hoses, drain lines, separators, treaters, tanks, and associated 
equipment. You must control and direct facility drains toward a central 
collection sump to prevent the facility from having a discharge as 
described in Sec. 112.1(b). Where drains and sumps are not practicable, 
you must remove oil contained in collection equipment as often as 
necessary to prevent overflow.
    (c) For facilities employing a sump system, provide adequately sized 
sump and drains and make available a spare pump to remove liquid from 
the sump and assure that oil does not escape. You must employ a 
regularly scheduled preventive maintenance inspection and testing 
program to assure reliable operation of the liquid removal system and 
pump start-up device. Redundant automatic sump pumps and control devices 
may be required on some installations.
    (d) At facilities with areas where separators and treaters are 
equipped with dump valves which predominantly fail in the closed 
position and where pollution risk is high, specially equip the facility 
to prevent the discharge of oil. You must prevent the discharge of oil 
by:
    (1) Extending the flare line to a diked area if the separator is 
near shore;
    (2) Equipping the separator with a high liquid level sensor that 
will automatically shut in wells producing to the separator; or
    (3) Installing parallel redundant dump valves.
    (e) Equip atmospheric storage or surge containers with high liquid 
level sensing devices that activate an alarm or control the flow, or 
otherwise prevent discharges.
    (f) Equip pressure containers with high and low pressure sensing 
devices that activate an alarm or control the flow.
    (g) Equip containers with suitable corrosion protection.
    (h) Prepare and maintain at the facility a written procedure within 
the Plan for inspecting and testing pollution prevention equipment and 
systems.

[[Page 48]]

    (i) Conduct testing and inspection of the pollution prevention 
equipment and systems at the facility on a scheduled periodic basis, 
commensurate with the complexity, conditions, and circumstances of the 
facility and any other appropriate regulations. You must use simulated 
discharges for testing and inspecting human and equipment pollution 
control and countermeasure systems.
    (j) Describe in detailed records surface and subsurface well shut-in 
valves and devices in use at the facility for each well sufficiently to 
determine their method of activation or control, such as pressure 
differential, change in fluid or flow conditions, combination of 
pressure and flow, manual or remote control mechanisms.
    (k) Install a BOP assembly and well control system during workover 
operations and before drilling below any casing string. The BOP assembly 
and well control system must be capable of controlling any well-head 
pressure that may be encountered while the BOP assembly and well control 
system are on the well.
    (l) Equip all manifolds (headers) with check valves on individual 
flowlines.
    (m) Equip the flowline with a high pressure sensing device and shut-
in valve at the wellhead if the shut-in well pressure is greater than 
the working pressure of the flowline and manifold valves up to and 
including the header valves. Alternatively you may provide a pressure 
relief system for flowlines.
    (n) Protect all piping appurtenant to the facility from corrosion, 
such as with protective coatings or cathodic protection.
    (o) Adequately protect sub-marine piping appurtenant to the facility 
against environmental stresses and other activities such as fishing 
operations.
    (p) Maintain sub-marine piping appurtenant to the facility in good 
operating condition at all times. You must periodically and according to 
a schedule inspect or test such piping for failures. You must document 
and keep a record of such inspections or tests at the facility.

Sec. 112.12  Spill Prevention, Control, and Countermeasure Plan 
requirements.

    If you are the owner or operator of an onshore facility, you must:
    (a) Meet the general requirements for the Plan listed under Sec. 
112.7, and the specific discharge prevention and containment procedures 
listed in this section.
    (b) Facility drainage. (1) Restrain drainage from diked storage 
areas by valves to prevent a discharge into the drainage system or 
facility effluent treatment system, except where facility systems are 
designed to control such discharge. You may empty diked areas by pumps 
or ejectors; however, you must manually activate these pumps or ejectors 
and must inspect the condition of the accumulation before starting, to 
ensure no oil will be discharged.
    (2) Use valves of manual, open-and-closed design, for the drainage 
of diked areas. You may not use flapper-type drain valves to drain diked 
areas. If your facility drainage drains directly into a watercourse and 
not into an on-site wastewater treatment plant, you must inspect and may 
drain uncontaminated retained stormwater, subject to the requirements of 
paragraphs (c)(3)(ii), (iii), and (iv) of this section.
    (3) Design facility drainage systems from undiked areas with a 
potential for a discharge (such as where piping is located outside 
containment walls or where tank truck discharges may occur outside the 
loading area) to flow into ponds, lagoons, or catchment basins designed 
to retain oil or return it to the facility. You must not locate 
catchment basins in areas subject to periodic flooding.

[[Page 49]]

    (4) If facility drainage is not engineered as in paragraph (b)(3) of 
this section, equip the final discharge of all ditches inside the 
facility with a diversion system that would, in the event of an 
uncontrolled discharge, retain oil in the facility.
    (5) Where drainage waters are treated in more than one treatment 
unit and such treatment is continuous, and pump transfer is needed, 
provide two ``lift'' pumps and permanently install at least one of the 
pumps. Whatever techniques you use, you must engineer facility drainage 
systems to prevent a discharge as described in Sec. 112.1(b) in case 
there is an equipment failure or human error at the facility.
    (c) Bulk storage containers. (1) Not use a container for the storage 
of oil unless its material and construction are compatible with the 
material stored and conditions of storage such as pressure and 
temperature.
    (2) Construct all bulk storage tank installations (except mobile 
refuelers and other non-transportation-related tank trucks) so that you 
provide a secondary means of containment for the entire capacity of the 
largest single container and sufficient freeboard to contain 
precipitation. You must ensure that diked areas are sufficiently 
impervious to contain discharged oil. Dikes, containment curbs, and pits 
are commonly employed for this purpose. You may also use an alternative 
system consisting of a drainage trench enclosure that must be arranged 
so that any discharge will terminate and be safely confined in a 
facility catchment basin or holding pond.
    (3) Not allow drainage of uncontaminated rainwater from the diked 
area into a storm drain or discharge of an effluent into an open 
watercourse, lake, or pond, bypassing the facility treatment system 
unless you:
    (i) Normally keep the bypass valve sealed closed.
    (ii) Inspect the retained rainwater to ensure that its presence will 
not cause a discharge as described in Sec. 112.1(b).
    (iii) Open the bypass valve and reseal it following drainage under 
responsible supervision; and
    (iv) Keep adequate records of such events, for example, any records 
required under permits issued in accordance with Sec. Sec. 122.41(j)(2) 
and 122.41(m)(3) of this chapter.
    (4) Protect any completely buried metallic storage tank installed on 
or after January 10, 1974 from corrosion by coatings or cathodic 
protection compatible with local soil conditions. You must regularly 
leak test such completely buried metallic storage tanks.
    (5) Not use partially buried or bunkered metallic tanks for the 
storage of oil, unless you protect the buried section of the tank from 
corrosion. You must protect partially buried and bunkered tanks from 
corrosion by coatings or cathodic protection compatible with local soil 
conditions.
    (6) Bulk storage container inspections.
    (i) Except for containers that meet the criteria provided in 
paragraph (c)(6)(ii) of this section, test or inspect each aboveground 
container for integrity on a regular schedule and whenever you make 
material repairs. You must determine, in accordance with industry 
standards, the appropriate qualifications for personnel performing tests 
and inspections, the frequency and type of testing and inspections, 
which take into account container size, configuration, and design (such 
as containers that are: shop-built, field-erected, skid-mounted, 
elevated, equipped with a liner, double-walled, or partially buried). 
Examples of these integrity tests include, but are not limited to: 
Visual inspection, hydrostatic testing, radiographic testing, ultrasonic 
testing, acoustic emissions testing, or other systems of non-destructive 
testing. You must keep comparison records and you must also inspect the 
container's supports and foundations. In addition, you must frequently 
inspect the outside of the container for signs of deterioration, 
discharges, or accumulation of oil inside diked areas. Records of 
inspections and tests kept under usual and customary business practices 
satisfy the recordkeeping requirements of this paragraph.
    (ii) For bulk storage containers that are subject to 21 CFR part 
110, are elevated, constructed of austenitic stainless steel, have no 
external insulation, and are shop-fabricated, conduct formal visual 
inspection on a regular

[[Page 50]]

schedule. In addition, you must frequently inspect the outside of the 
container for signs of deterioration, discharges, or accumulation of oil 
inside diked areas. You must determine and document in the Plan the 
appropriate qualifications for personnel performing tests and 
inspections. Records of inspections and tests kept under usual and 
customary business practices satisfy the recordkeeping requirements of 
this paragraph (c)(6).
    (7) Control leakage through defective internal heating coils by 
monitoring the steam return and exhaust lines for contamination from 
internal heating coils that discharge into an open watercourse, or pass 
the steam return or exhaust lines through a settling tank, skimmer, or 
other separation or retention system.
    (8) Engineer or update each container installation in accordance 
with good engineering practice to avoid discharges. You must provide at 
least one of the following devices:
    (i) High liquid level alarms with an audible or visual signal at a 
constantly attended operation or surveillance station. In smaller 
facilities an audible air vent may suffice.
    (ii) High liquid level pump cutoff devices set to stop flow at a 
predetermined container content level.
    (iii) Direct audible or code signal communication between the 
container gauger and the pumping station.
    (iv) A fast response system for determining the liquid level of each 
bulk storage container such as digital computers, telepulse, or direct 
vision gauges. If you use this alternative, a person must be present to 
monitor gauges and the overall filling of bulk storage containers.
    (v) You must regularly test liquid level sensing devices to ensure 
proper operation.
    (9) Observe effluent treatment facilities frequently enough to 
detect possible system upsets that could cause a discharge as described 
in Sec. 112.1(b).
    (10) Promptly correct visible discharges which result in a loss of 
oil from the container, including but not limited to seams, gaskets, 
piping, pumps, valves, rivets, and bolts. You must promptly remove any 
accumulations of oil in diked areas.
    (11) Position or locate mobile or portable oil storage containers to 
prevent a discharge as described in Sec. 112.1(b). Except for mobile 
refuelers and other non-transportation-related tank trucks, you must 
furnish a secondary means of containment, such as a dike or catchment 
basin, sufficient to contain the capacity of the largest single 
compartment or container with sufficient freeboard to contain 
precipitation.
    (d) Facility transfer operations, pumping, and facility process. (1) 
Provide buried piping that is installed or replaced on or after August 
16, 2002, with a protective wrapping and coating. You must also 
cathodically protect such buried piping installations or otherwise 
satisfy the corrosion protection standards for piping in part 280 of 
this chapter or a State program approved under part 281 of this chapter. 
If a section of buried line is exposed for any reason, you must 
carefully inspect it for deterioration. If you find corrosion damage, 
you must undertake additional examination and corrective action as 
indicated by the magnitude of the damage.
    (2) Cap or blank-flange the terminal connection at the transfer 
point and mark it as to origin when piping is not in service or is in 
standby service for an extended time.
    (3) Properly design pipe supports to minimize abrasion and corrosion 
and allow for expansion and contraction.
    (4) Regularly inspect all aboveground valves, piping, and 
appurtenances. During the inspection you must assess the general 
condition of items, such as flange joints, expansion joints, valve 
glands and bodies, catch pans, pipeline supports, locking of valves, and 
metal surfaces. You must also conduct integrity and leak testing of 
buried piping at the time of installation, modification, construction, 
relocation, or replacement.
    (5) Warn all vehicles entering the facility to be sure that no 
vehicle will endanger aboveground piping or other oil transfer 
operations.

Sec. 112.20  Facility response plans.

    (a) The owner or operator of any non-transportation-related onshore 
facility that, because of its location, could reasonably be expected to 
cause substantial harm to the environment by discharging oil into or on 
the navigable waters or adjoining shorelines shall prepare and submit a 
facility response plan to the Regional Administrator, according to the 
following provisions:
    (1) For the owner or operator of a facility in operation on or 
before February 18, 1993 who is required to prepare and submit a 
response plan under 33 U.S.C. 1321(j)(5), the Oil Pollution Act of 1990 
(Pub. L. 101-380, 33 U.S.C. 2701 et seq.) requires the submission of a 
response plan that satisfies the requirements of 33 U.S.C. 1321(j)(5) no 
later than February 18, 1993.
    (i) The owner or operator of an existing facility that was in 
operation on or before February 18, 1993 who submitted a response plan 
by February 18, 1993 shall revise the response plan to satisfy the 
requirements of this section and resubmit the response plan or updated 
portions of the response plan to the Regional Administrator by February 
18, 1995.
    (ii) The owner or operator of an existing facility in operation on 
or before February 18, 1993 who failed to submit a response plan by 
February 18, 1993 shall prepare and submit a response plan that 
satisfies the requirements of this section to the Regional Administrator 
before August 30, 1994.
    (2) The owner or operator of a facility in operation on or after 
August 30, 1994 that satisfies the criteria in paragraph (f)(1) of this 
section or that is notified by the Regional Administrator pursuant to 
paragraph (b) of this section shall prepare and submit a facility 
response plan that satisfies the requirements of this section to the 
Regional Administrator.
    (i) For a facility that commenced operations after February 18, 1993 
but prior to August 30, 1994, and is required to prepare and submit a 
response plan based on the criteria in paragraph (f)(1) of this section, 
the owner or operator shall submit the response plan or updated portions 
of the response plan, along with a completed version of the response 
plan cover sheet contained in appendix F to this part, to the Regional 
Administrator prior to August 30, 1994.
    (ii) For a newly constructed facility that commences operation after 
August 30, 1994, and is required to prepare and submit a response plan 
based on the criteria in paragraph (f)(1) of this section, the owner or 
operator shall submit the response plan, along with a completed version 
of the response plan cover sheet contained in appendix F to this part, 
to the Regional Administrator prior to the start of operations 
(adjustments to the response plan to reflect changes that occur at the 
facility during the start-up phase of operations must be submitted to 
the Regional Administrator after an operational trial period of 60 
days).
    (iii) For a facility required to prepare and submit a response plan 
after August 30, 1994, as a result of a planned change in design, 
construction, operation, or maintenance that renders the facility 
subject to the criteria in paragraph (f)(1) of this section, the owner 
or operator shall submit the response plan, along with a completed 
version of the response plan cover sheet contained in appendix F to this 
part, to the Regional Administrator before the portion of the facility 
undergoing change commences operations (adjustments to the response plan 
to reflect changes that occur at the facility during the start-up phase 
of operations must be submitted to the Regional Administrator after an 
operational trial period of 60 days).
    (iv) For a facility required to prepare and submit a response plan 
after August 30, 1994, as a result of an unplanned event or change in 
facility characteristics that renders the facility subject to the 
criteria in paragraph (f)(1) of this section, the owner or operator 
shall submit the response plan, along with a completed version of the 
response plan cover sheet contained in appendix F to this part, to the 
Regional Administrator within six months of the unplanned event or 
change.

[[Page 52]]

    (3) In the event the owner or operator of a facility that is 
required to prepare and submit a response plan uses an alternative 
formula that is comparable to one contained in appendix C to this part 
to evaluate the criterion in paragraph (f)(1)(ii)(B) or (f)(1)(ii)(C) of 
this section, the owner or operator shall attach documentation to the 
response plan cover sheet contained in appendix F to this part that 
demonstrates the reliability and analytical soundness of the alternative 
formula.
    (4) Preparation and submission of response plans--Animal fat and 
vegetable oil facilities. The owner or operator of any non-
transportation-related facility that handles, stores, or transports 
animal fats and vegetable oils must prepare and submit a facility 
response plan as follows:
    (i) Facilities with approved plans. The owner or operator of a 
facility with a facility response plan that has been approved under 
paragraph (c) of this section by July 31, 2000 need not prepare or 
submit a revised plan except as otherwise required by paragraphs (b), 
(c), or (d) of this section.
    (ii) Facilities with plans that have been submitted to the Regional 
Administrator. Except for facilities with approved plans as provided in 
paragraph (a)(4)(i) of this section, the owner or operator of a facility 
that has submitted a response plan to the Regional Administrator prior 
to July 31, 2000 must review the plan to determine if it meets or 
exceeds the applicable provisions of this part. An owner or operator 
need not prepare or submit a new plan if the existing plan meets or 
exceeds the applicable provisions of this part. If the plan does not 
meet or exceed the applicable provisions of this part, the owner or 
operator must prepare and submit a new plan by September 28, 2000.
    (iii) Newly regulated facilities. The owner or operator of a newly 
constructed facility that commences operation after July 31, 2000 must 
prepare and submit a plan to the Regional Administrator in accordance 
with paragraph (a)(2)(ii) of this section. The plan must meet or exceed 
the applicable provisions of this part. The owner or operator of an 
existing facility that must prepare and submit a plan after July 31, 
2000 as a result of a planned or unplanned change in facility 
characteristics that causes the facility to become regulated under 
paragraph (f)(1) of this section, must prepare and submit a plan to the 
Regional Administrator in accordance with paragraph (a)(2)(iii) or (iv) 
of this section, as appropriate. The plan must meet or exceed the 
applicable provisions of this part.
    (iv) Facilities amending existing plans. The owner or operator of a 
facility submitting an amended plan in accordance with paragraph (d) of 
this section after July 31, 2000, including plans that had been 
previously approved, must also review the plan to determine if it meets 
or exceeds the applicable provisions of this part. If the plan does not 
meet or exceed the applicable provisions of this part, the owner or 
operator must revise and resubmit revised portions of an amended plan to 
the Regional Administrator in accordance with paragraph (d) of this 
section, as appropriate. The plan must meet or exceed the applicable 
provisions of this part.
    (b)(1) The Regional Administrator may at any time require the owner 
or operator of any non-transportation-related onshore facility to 
prepare and submit a facility response plan under this section after 
considering the factors in paragraph (f)(2) of this section. If such a 
determination is made, the Regional Administrator shall notify the 
facility owner or operator in writing and shall provide a basis for the 
determination. If the Regional Administrator notifies the owner or 
operator in writing of the requirement to prepare and submit a response 
plan under this section, the owner or operator of the facility shall 
submit the response plan to the Regional Administrator within six months 
of receipt of such written notification.
    (2) The Regional Administrator shall review plans submitted by such 
facilities to determine whether the facility could, because of its 
location, reasonably be expected to cause significant and substantial 
harm to the environment by discharging oil into or on the navigable 
waters or adjoining shorelines.

[[Page 53]]

    (c) The Regional Administrator shall determine whether a facility 
could, because of its location, reasonably be expected to cause 
significant and substantial harm to the environment by discharging oil 
into or on the navigable waters or adjoining shorelines, based on the 
factors in paragraph (f)(3) of this section. If such a determination is 
made, the Regional Administrator shall notify the owner or operator of 
the facility in writing and:
    (1) Promptly review the facility response plan;
    (2) Require amendments to any response plan that does not meet the 
requirements of this section;
    (3) Approve any response plan that meets the requirements of this 
section; and
    (4) Review each response plan periodically thereafter on a schedule 
established by the Regional Administrator provided that the period 
between plan reviews does not exceed five years.
    (d)(1) The owner or operator of a facility for which a response plan 
is required under this part shall revise and resubmit revised portions 
of the response plan within 60 days of each facility change that 
materially may affect the response to a worst case discharge, including:
    (i) A change in the facility's configuration that materially alters 
the information included in the response plan;
    (ii) A change in the type of oil handled, stored, or transferred 
that materially alters the required response resources;
    (iii) A material change in capabilities of the oil spill removal 
organization(s) that provide equipment and personnel to respond to 
discharges of oil described in paragraph (h)(5) of this section;
    (iv) A material change in the facility's spill prevention and 
response equipment or emergency response procedures; and
    (v) Any other changes that materially affect the implementation of 
the response plan.
    (2) Except as provided in paragraph (d)(1) of this section, 
amendments to personnel and telephone number lists included in the 
response plan and a change in the oil spill removal organization(s) that 
does not result in a material change in support capabilities do not 
require approval by the Regional Administrator. Facility owners or 
operators shall provide a copy of such changes to the Regional 
Administrator as the revisions occur.
    (3) The owner or operator of a facility that submits changes to a 
response plan as provided in paragraph (d)(1) or (d)(2) of this section 
shall provide the EPA-issued facility identification number (where one 
has been assigned) with the changes.
    (4) The Regional Administrator shall review for approval changes to 
a response plan submitted pursuant to paragraph (d)(1) of this section 
for a facility determined pursuant to paragraph (f)(3) of this section 
to have the potential to cause significant and substantial harm to the 
environment.
    (e) If the owner or operator of a facility determines pursuant to 
paragraph (a)(2) of this section that the facility could not, because of 
its location, reasonably be expected to cause substantial harm to the 
environment by discharging oil into or on the navigable waters or 
adjoining shorelines, the owner or operator shall complete and maintain 
at the facility the certification form contained in appendix C to this 
part and, in the event an alternative formula that is comparable to one 
contained in appendix C to this part is used to evaluate the criterion 
in paragraph (f)(1)(ii)(B) or (f)(1)(ii)(C) of this section, the owner 
or operator shall attach documentation to the certification form that 
demonstrates the reliability and analytical soundness of the comparable 
formula and shall notify the Regional Administrator in writing that an 
alternative formula was used.
    (f)(1) A facility could, because of its location, reasonably be 
expected to cause substantial harm to the environment by discharging oil 
into or on the navigable waters or adjoining shorelines pursuant to 
paragraph (a)(2) of this section, if it meets any of the following 
criteria applied in accordance with the flowchart contained in 
attachment C-I to appendix C to this part:
    (i) The facility transfers oil over water to or from vessels and has 
a total oil storage capacity greater than or equal to 42,000 gallons; or

[[Page 54]]

    (ii) The facility's total oil storage capacity is greater than or 
equal to 1 million gallons, and one of the following is true:
    (A) The facility does not have secondary containment for each 
aboveground storage area sufficiently large to contain the capacity of 
the largest aboveground oil storage tank within each storage area plus 
sufficient freeboard to allow for precipitation;
    (B) The facility is located at a distance (as calculated using the 
appropriate formula in appendix C to this part or a comparable formula) 
such that a discharge from the facility could cause injury to fish and 
wildlife and sensitive environments. For further description of fish and 
wildlife and sensitive environments, see Appendices I, II, and III of 
the ``Guidance for Facility and Vessel Response Plans: Fish and Wildlife 
and Sensitive Environments'' (see appendix E to this part, section 13, 
for availability) and the applicable Area Contingency Plan prepared 
pursuant to section 311(j)(4) of the Clean Water Act;
    (C) The facility is located at a distance (as calculated using the 
appropriate formula in appendix C to this part or a comparable formula) 
such that a discharge from the facility would shut down a public 
drinking water intake; or
    (D) The facility has had a reportable oil discharge in an amount 
greater than or equal to 10,000 gallons within the last 5 years.
    (2)(i) To determine whether a facility could, because of its 
location, reasonably be expected to cause substantial harm to the 
environment by discharging oil into or on the navigable waters or 
adjoining shorelines pursuant to paragraph (b) of this section, the 
Regional Administrator shall consider the following:
    (A) Type of transfer operation;
    (B) Oil storage capacity;
    (C) Lack of secondary containment;
    (D) Proximity to fish and wildlife and sensitive environments and 
other areas determined by the Regional Administrator to possess 
ecological value;
    (E) Proximity to drinking water intakes;
    (F) Spill history; and
    (G) Other site-specific characteristics and environmental factors 
that the Regional Administrator determines to be relevant to protecting 
the environment from harm by discharges of oil into or on navigable 
waters or adjoining shorelines.
    (ii) Any person, including a member of the public or any 
representative from a Federal, State, or local agency who believes that 
a facility subject to this section could, because of its location, 
reasonably be expected to cause substantial harm to the environment by 
discharging oil into or on the navigable waters or adjoining shorelines 
may petition the Regional Administrator to determine whether the 
facility meets the criteria in paragraph (f)(2)(i) of this section. Such 
petition shall include a discussion of how the factors in paragraph 
(f)(2)(i) of this section apply to the facility in question. The RA 
shall consider such petitions and respond in an appropriate amount of 
time.
    (3) To determine whether a facility could, because of its location, 
reasonably be expected to cause significant and substantial harm to the 
environment by discharging oil into or on the navigable waters or 
adjoining shorelines, the Regional Administrator may consider the 
factors in paragraph (f)(2) of this section as well as the following:
    (i) Frequency of past discharges;
    (ii) Proximity to navigable waters;
    (iii) Age of oil storage tanks; and
    (iv) Other facility-specific and Region-specific information, 
including local impacts on public health.
    (g)(1) All facility response plans shall be consistent with the 
requirements of the National Oil and Hazardous Substance Pollution 
Contingency Plan (40 CFR part 300) and applicable Area Contingency Plans 
prepared pursuant to section 311(j)(4) of the Clean Water Act. The 
facility response plan should be coordinated with the local emergency 
response plan developed by the local emergency planning committee under 
section 303 of Title III of the Superfund Amendments and Reauthorization 
Act of 1986 (42 U.S.C. 11001 et seq.). Upon request, the owner or 
operator should provide a copy of the facility response plan to the 
local emergency planning

Commission, and Local Emergency Planning Committee;
    (E) Assess the interaction of the discharged substance with water 
and/or other substances stored at the facility and notify response 
personnel at the scene of that assessment;
    (F) Assess the possible hazards to human health and the environment 
due to the release. This assessment must consider both the direct and 
indirect effects of the release (i.e., the effects of any toxic, 
irritating, or asphyxiating gases that may be generated, or the effects 
of any hazardous surface water runoffs from water or chemical agents 
used to control fire and heat-induced explosion);
    (G) Assess and implement prompt removal actions to contain and 
remove the substance released;
    (H) Coordinate rescue and response actions as previously arranged 
with all response personnel;
    (I) Use authority to immediately access company funding to initiate 
cleanup activities; and
    (J) Direct cleanup activities until properly relieved of this 
responsibility.
    (4) Hazard evaluation. The response plan shall discuss the 
facility's known or reasonably identifiable history of discharges 
reportable under 40 CFR part 110 for the entire life of the facility and 
shall identify areas within the facility where discharges could occur 
and what the potential effects of the discharges would be on the 
affected environment. To assess the range of areas potentially affected, 
owners or operators shall, where appropriate, consider the distance 
calculated in paragraph (f)(1)(ii) of this section to determine whether 
a facility could, because of its location, reasonably be expected to 
cause substantial harm to the environment by discharging oil into or on 
the navigable waters or adjoining shorelines.
    (5) Response planning levels. The response plan shall include 
discussion of specific planning scenarios for:
    (i) A worst case discharge, as calculated using the appropriate 
worksheet in appendix D to this part. In cases where the Regional 
Administrator determines that the worst case discharge volume calculated 
by the facility is not appropriate, the Regional Administrator may 
specify the worst case discharge amount to be used for response planning 
at the facility. For complexes, the worst case planning quantity shall 
be the larger of the amounts calculated for each component of the 
facility;
    (ii) A discharge of 2,100 gallons or less, provided that this amount 
is less than the worst case discharge amount. For complexes, this 
planning quantity shall be the larger of the amounts calculated for each 
component of the facility; and
    (iii) A discharge greater than 2,100 gallons and less than or equal 
to 36,000 gallons or 10 percent of the capacity of the largest tank at 
the facility, whichever is less, provided that this amount is less than 
the worst case discharge amount. For complexes, this planning quantity 
shall be the larger of the amounts calculated for each component of the 
facility.

contracted personnel under the response plan to ensure the safety of the 
facility and to mitigate or prevent discharges described in paragraph 
(h)(5) of this section or the substantial threat of such discharges;
    (ii) A description of the equipment to be used for each scenario;
    (iii) Plans to dispose of contaminated cleanup materials; and
    (iv) Measures to provide adequate containment and drainage of 
discharged oil.
    (8) Self-inspection, drills/exercises, and response training. The 
response plan shall include:
    (i) A checklist and record of inspections for tanks, secondary 
containment, and response equipment;
    (ii) A description of the drill/exercise program to be carried out 
under the response plan as described in Sec. 112.21;
    (iii) A description of the training program to be carried out under 
the response plan as described in Sec. 112.21; and
    (iv) Logs of discharge prevention meetings, training sessions, and 
drills/exercises. These logs may be maintained as an annex to the 
response plan.
    (9) Diagrams. The response plan shall include site plan and drainage 
plan diagrams.
    (10) Security systems. The response plan shall include a description 
of facility security systems.
    (11) Response plan cover sheet. The response plan shall include a 
completed response plan cover sheet provided in section 2.0 of appendix 
F to this part.
    (i)(1) In the event the owner or operator of a facility does not 
agree with the Regional Administrator's determination that the facility 
could, because of its location, reasonably be expected to cause 
substantial harm or significant and substantial harm to the environment 
by discharging oil into or on the navigable waters or adjoining 
shorelines, or that amendments to the facility response plan are 
necessary prior to approval, such as changes to the worst case discharge 
planning volume, the owner or operator may submit a request for 
reconsideration to the Regional Administrator and provide additional 
information and data in writing to support the request. The request and 
accompanying information must be submitted to the Regional Administrator 
within 60 days of receipt of notice of the Regional Administrator's 
original decision. The Regional Administrator shall consider the request 
and render a decision as rapidly as practicable.
    (2) In the event the owner or operator of a facility believes a 
change in the facility's classification status is warranted because of 
an unplanned event or change in the facility's characteristics (i.e., 
substantial harm or significant and substantial harm), the owner or 
operator may submit a request for reconsideration to the Regional 
Administrator and provide additional information and data in writing to 
support the request. The Regional Administrator shall consider the 
request and render a decision as rapidly as practicable.
    (3) After a request for reconsideration under paragraph (i)(1) or 
(i)(2) of this section has been denied by the Regional Administrator, an 
owner or operator may appeal a determination made by the Regional 
Administrator. The appeal shall be made to the EPA Administrator and 
shall be made in writing within 60 days of receipt of the decision from 
the Regional Administrator that the request for reconsideration was 
denied. A complete copy of the appeal must be sent to the Regional 
Administrator at the time the appeal is made. The appeal shall contain a 
clear and concise statement of the issues and points of fact in the 
case. It also may contain additional information from the owner or 
operator, or from any other person. The EPA Administrator may request 
additional information from the owner or operator, or from any other 
person. The EPA Administrator shall render a decision as rapidly as

2.0 Description of Screening Criteria for the Substantial Harm Flowchart

    A facility that has the potential to cause substantial harm to the 
environment in the event of a discharge must prepare and submit a 
facility-specific response plan to EPA in accordance with appendix F to 
this part. A description of the screening criteria for the substantial 
harm flowchart is provided below:
    2.1 Non-Transportation-Related Facilities With a Total Oil Storage 
Capacity Greater Than or Equal to 42,000 Gallons Where Operations 
Include Over-Water Transfers of Oil. A non-transportation-related 
facility with a total oil storage capacity greater than or equal to 
42,000 gallons that transfers oil over water to or from vessels must 
submit a response plan to EPA. Daily oil transfer operations at these 
types of facilities occur between barges and vessels and onshore bulk 
storage tanks over open water. These facilities are located adjacent to 
navigable water.
    2.2 Lack of Adequate Secondary Containment at Facilities With a 
Total Oil Storage Capacity Greater Than or Equal to 1 Million Gallons. 
Any facility with a total oil storage capacity greater than or equal to 
1 million gallons without secondary containment sufficiently large to 
contain the capacity of the largest aboveground oil storage tank within 
each area plus sufficient freeboard to allow for precipitation must 
submit a response plan to EPA. Secondary containment structures that 
meet the standard of good engineering practice for the purposes of this 
part include berms, dikes, retaining walls, curbing, culverts, gutters, 
or other drainage systems.
    2.3 Proximity to Fish and Wildlife and Sensitive Environments at 
Facilities With a Total Oil Storage Capacity Greater Than or Equal to 1 
Million Gallons. A facility with a total oil storage capacity greater 
than or equal to 1 million gallons must submit its response plan if it 
is located at a distance such that a discharge from the facility could 
cause injury (as defined at 40 CFR 112.2) to fish and wildlife and 
sensitive environments. For further description of fish and wildlife and 
sensitive environments, see Appendices I, II, and III to DOC/NOAA's 
``Guidance for Facility and Vessel Response Plans: Fish and Wildlife and 
Sensitive Environments'' (see appendix E to this part, section 13, for 
availability) and the applicable Area Contingency Plan. Facility owners 
or operators must determine the distance at which an oil discharge could 
cause injury to fish and wildlife and sensitive environments using the 
appropriate formula presented in Attachment C-III to this appendix or a 
comparable formula.
    2.4 Proximity to Public Drinking Water Intakes at Facilities with a 
Total Oil Storage Capacity Greater than or Equal to 1 Million Gallons A 
facility with a total oil storage capacity greater than or equal to 1 
million gallons must submit its response plan if it is located at a 
distance such that a discharge from the facility would shut down a 
public drinking water intake, which is analogous to a public water 
system as described at 40 CFR 143.2(c). The distance at which an oil 
discharge from an SPCC-regulated facility would shut down a public 
drinking water intake shall be calculated using the appropriate formula 
presented in Attachment C-III to this appendix or a comparable formula.
    2.5 Facilities That Have Experienced Reportable Oil Discharges in an 
Amount Greater Than or Equal to 10,000 Gallons Within the Past 5 Years 
and That Have a Total Oil Storage Capacity Greater Than or Equal to 1 
Million Gallons. A facility's oil spill history within the past 5 years 
shall be considered in the evaluation for substantial harm. Any facility 
with a total oil storage capacity greater than or equal to 1 million 
gallons that has experienced a reportable oil discharge in an amount 
greater than or equal to 10,000 gallons within the past 5 years must 
submit a response plan to EPA.

   3.0 Certification for Facilities That Do Not Pose Substantial Harm

    If the facility does not meet the substantial harm criteria listed 
in Attachment C-I to this appendix, the owner or operator shall complete 
and maintain at the facility the certification form contained in 
Attachment C-II to this appendix. In the event an alternative formula 
that is comparable to the one in this appendix is used to evaluate the 
substantial harm criteria, the owner or operator shall attach 
documentation to the certification form that demonstrates the 
reliability and analytical soundness of the comparable formula and shall 
notify the Regional Administrator in writing that an alternative formula 
was used.

         Attachment C-III--Calculation of the Planning Distance

                            1.0 Introduction

    1.1 The facility owner or operator must evaluate whether the 
facility is located at a distance such that a discharge from the 
facility could cause injury to fish and wildlife and sensitive 
environments or disrupt operations at a public drinking water intake. To 
quantify that distance, EPA considered oil transport mechanisms over 
land and on still, tidal influence, and moving navigable waters. EPA has 
determined that the primary concern for calculation of a planning 
distance is the transport of oil in navigable waters during adverse 
weather conditions. Therefore, two formulas have been developed to 
determine distances for planning purposes from the point of discharge at 
the facility to the potential site of impact on moving and still waters, 
respectively. The formula for oil transport on moving navigable water is 
based on the velocity of the water body and the time interval for 
arrival of response resources. The still water formula accounts for the 
spread of discharged oil over the surface of the water. The method to 
determine oil transport on tidal influence areas is based on the type of 
oil discharged and the distance down current during ebb tide and up 
current during flood tide to the point of maximum tidal influence.
    1.2 EPA's formulas were designed to be simple to use. However, 
facility owners or operators may calculate planning distances using more 
sophisticated formulas, which take into account broader scientific or 
engineering principles, or local conditions. Such comparable formulas 
may result in different planning distances than EPA's formulas. In the 
event that an alternative formula that is comparable to one contained in 
this appendix is used to evaluate the criterion in 40 CFR 
112.20(f)(1)(ii)(B) or (f)(1)(ii)(C), the owner or operator shall attach 
documentation to the response plan cover sheet contained in appendix F 
to this part that demonstrates the reliability and analytical soundness 
of the alternative formula and shall notify the Regional Administrator 
in

[[Page 64]]

writing that an alternative formula was used. \1\
---------------------------------------------------------------------------

    \1\ For persistent oils or non-persistent oils, a worst case 
trajectory model (i.e., an alternative formula) may be substituted for 
the distance formulas described in still, moving, and tidal waters, 
subject to Regional Administrator's review of the model. An example of 
an alternative formula that is comparable to the one contained in this 
appendix would be a worst case trajectory calculation based on credible 
adverse winds, currents, and/or river stages, over a range of seasons, 
weather conditions, and river stages. Based on historical information or 
a spill trajectory model, the Agency may require that additional fish 
and wildlife and sensitive environments or public drinking water intakes 
also be protected.
---------------------------------------------------------------------------

    1.3 A regulated facility may meet the criteria for the potential to 
cause substantial harm to the environment without having to perform a 
planning distance calculation. For facilities that meet the substantial 
harm criteria because of inadequate secondary containment or oil spill 
history, as listed in the flowchart in Attachment C-I to this appendix, 
calculation of the planning distance is unnecessary. For facilities that 
do not meet the substantial harm criteria for secondary containment or 
oil spill history as listed in the flowchart, calculation of a planning 
distance for proximity to fish and wildlife and sensitive environments 
and public drinking water intakes is required, unless it is clear 
without performing the calculation (e.g., the facility is located in a 
wetland) that these areas would be impacted.
    1.4 A facility owner or operator who must perform a planning 
distance calculation on navigable water is only required to do so for 
the type of navigable water conditions (i.e., moving water, still water, 
or tidal- influenced water) applicable to the facility. If a facility 
owner or operator determines that more than one type of navigable water 
condition applies, then the facility owner or operator is required to 
perform a planning distance calculation for each navigable water type to 
determine the greatest single distance that oil may be transported. As a 
result, the final planning distance for oil transport on water shall be 
the greatest individual distance rather than a summation of each 
calculated planning distance.
    1.5 The planning distance formula for transport on moving waterways 
contains three variables: the velocity of the navigable water (v), the 
response time interval (t), and a conversion factor (c). The velocity, 
v, is determined by using the Chezy-Manning equation, which, in this 
case, models the flood flow rate of water in open channels. The Chezy-
Manning equation contains three variables which must be determined by 
facility owners or operators. Manning's Roughness Coefficient (for flood 
flow rates), n, can be determined from Table 1 of this attachment. The 
hydraulic radius, r, can be estimated using the average mid-channel 
depth from charts provided by the sources listed in Table 2 of this 
attachment. The average slope of the river, s, can be determined using 
topographic maps that can be ordered from the U.S. Geological Survey, as 
listed in Table 2 of this attachment.
    1.6 Table 3 of this attachment contains specified time intervals for 
estimating the arrival of response resources at the scene of a 
discharge. Assuming no prior planning, response resources should be able 
to arrive at the discharge site within 12 hours of the discovery of any 
oil discharge in Higher Volume Port Areas and within 24 hours in Great 
Lakes and all other river, canal, inland, and nearshore areas. The 
specified time intervals in Table 3 of appendix C are to be used only to 
aid in the identification of whether a facility could cause substantial 
harm to the environment. Once it is determined that a plan must be 
developed for the facility, the owner or operator shall reference 
appendix E to this part to determine appropriate resource levels and 
response times. The specified time intervals of this appendix include a 
3-hour time period for deployment of boom and other response equipment. 
The Regional Administrator may identify additional areas as appropriate.

              2.0 Oil Transport on Moving Navigable Waters

    2.1 The facility owner or operator must use the following formula or 
a comparable formula as described in Sec. 112.20(a)(3) to calculate the 
planning distance for oil transport on moving navigable water:

d = v x t x c; where
d: the distance downstream from a facility within which fish and 
          wildlife and sensitive environments could be injured or a 
          public drinking water intake would be shut down in the event 
          of an oil discharge (in miles);
v: the velocity of the river/navigable water of concern (in ft/sec) as 
          determined by Chezy-Manning's equation (see below and Tables 1 
          and 2 of this attachment);
t: the time interval specified in Table 3 based upon the type of water 
          body and location (in hours); and
c: constant conversion factor 0.68 sec[omega] mile/hr[omega] ft (3600 
          sec/hr / 5280 ft/mile).

Additional information can be obtained from the following sources:
1. The State's Department of Natural Resources (DNR) or the State's Aids 
to Navigation office;
2. A knowledgeable local marina operator; or
3. A knowledgeable local water authority (e.g., State water commission)

    2.3 The average slope of the river (s) can be determined from the 
topographic maps using the following steps:
    (1) Locate the facility on the map.
    (2) Find the Normal Pool Elevation at the point of discharge from 
the facility into the water (A).
    (3) Find the Normal Pool Elevation of the public drinking water 
intake or fish and wildlife and sensitive environment located downstream 
(B) (Note: The owner or operator should use a minimum of 20 miles 
downstream as a cutoff to obtain the average slope if the location of a 
specific public drinking water intake or fish and wildlife and sensitive 
environment is unknown).
    (4) If the Normal Pool Elevation is not available, the elevation 
contours can be used to find the slope. Determine elevation of the water 
at the point of discharge from the facility (A). Determine the elevation 
of the

[[Page 66]]

water at the appropriate distance downstream (B). The formula presented 
below can be used to calculate the slope.
    (5) Determine the distance (in miles) between the facility and the 
public drinking water intake or fish and wildlife and sensitive 
environments (C).
    (6) Use the following formula to find the slope, which will be a 
unitless value: Average Slope=[(A-B) (ft)/C (miles)] x [1 mile/5280 
feet]
    2.4 If it is not feasible to determine the slope and mid-channel 
depth by the Chezy-Manning equation, then the river velocity can be 
approximated on- site. A specific length, such as 100 feet, can be 
marked off along the shoreline. A float can be dropped into the stream 
above the mark, and the time required for the float to travel the 
distance can be used to determine the velocity in feet per second. 
However, this method will not yield an average velocity for the length 
of the stream, but a velocity only for the specific location of 
measurement. In addition, the flow rate will vary depending on weather 
conditions such as wind and rainfall. It is recommended that facility 
owners or operators repeat the measurement under a variety of conditions 
to obtain the most accurate estimate of the surface water velocity under 
adverse weather conditions.
    2.5 The planning distance calculations for moving and still 
navigable waters are based on worst case discharges of persistent oils. 
Persistent oils are of concern because they can remain in the water for 
significant periods of time and can potentially exist in large 
quantities downstream. Owners or operators of facilities that store 
persistent as well as non-persistent oils may use a comparable formula. 
The volume of oil discharged is not included as part of the planning 
distance calculation for moving navigable waters. Facilities that will 
meet this substantial harm criterion are those with facility capacities 
greater than or equal to 1 million gallons. It is assumed that these 
facilities are capable of having an oil discharge of sufficient quantity 
to cause injury to fish and wildlife and sensitive environments or shut 
down a public drinking water intake. While owners or operators of 
transfer facilities that store greater than or equal to 42,000 gallons 
are not required to use a planning distance formula for purposes of the 
substantial harm criteria, they should use a planning distance 
calculation in the development of facility-specific response plans.

    2.6 Example of the Planning Distance Calculation for Oil Transport 
on Moving Navigable Waters. The following example provides a sample 
calculation using the planning distance formula for a facility 
discharging oil into the Monongahela River:
    (1) Solve for v by evaluating n, r, and s for the Chezy-Manning 
equation:
    Find the roughness coefficient, n, on Table 1 of this attachment for 
a regular section of a major stream with a top width greater than 100 
feet. The top width of the river can be found from the topographic map.

n = 0.035.
Find slope, s, where A = 727 feet, B = 710 feet, and C = 25 miles.

Solving:
s = [(727 ft - 1710 ft) / 25 miles] x [1 mile/5280 feet] = 1.3 x 
          10-4
    The average mid-channel depth is found by averaging the mid-channel 
depth for each mile along the length of the river between the facility 
and the public drinking water intake or the fish or wildlife or 
sensitive environment (or 20 miles downstream if applicable). This value 
is multiplied by 0.667 to obtain the hydraulic radius. The mid-channel 
depth is found by obtaining values for r and s from the sources shown in 
Table 2 for the Monongahela River.

Solving:
r = 0.667 x 20 feet = 13.33 feet
Solve for v using:
v = 1.5/n x r\2/3\ x s\1/2\:
v = [1.5/0.035] x (13.33)\2/3\ x (1.3 x 10-4)\1/2\
v = 2.73 feet/second

    (2) Find t from Table 3 of this attachment. The Monongahela River's 
resource response time is 27 hours.
    (3) Solve for planning distance, d:

d = v x t x c
d = (2.73 ft/sec) x (27 hours) x (0.68 sec[omega] mile/hr[omega] ft)
d = 50 miles

Therefore, 50 miles downstream is the appropriate planning distance for 
this facility.

                    3.0 Oil Transport on Still Water

    3.1 For bodies of water including lakes or ponds that do not have a 
measurable velocity, the spreading of the oil over the surface must be 
considered. Owners or operators of facilities located next to still 
water bodies may use a comparable means of calculating

[[Page 67]]

the planning distance. If a comparable formula is used, documentation of 
the reliability and analytical soundness of the comparable calculation 
must be attached to the response plan cover sheet.
    3.2 Example of the Planning Distance Calculation for Oil Transport 
on Still Water. To assist those facilities which could potentially 
discharge into a still body of water, the following analysis was 
performed to provide an example of the type of formula that may be used 
to calculate the planning distance. For this example, a worst case 
discharge of 2,000,000 gallons is used.
    (1) The surface area in square feet covered by an oil discharge on 
still water, A1, can be determined by the following formula, \2\ where V 
is the volume of the discharge in gallons and C is a constant conversion 
factor:
---------------------------------------------------------------------------

    \2\ Huang, J.C. and Monastero, F.C., 1982. Review of the State-of-
the-Art of Oil Pollution Models. Final report submitted to the American 
Petroleum Institute by Raytheon Ocean Systems, Co., East Providence, 
Rhode Island.
---------------------------------------------------------------------------

A1 = 10\5\ x V\3/4\ x C
C = 0.1643
A1 = 10\5\ x (2,000,000 gallons)\3/4\ x (0.1643)
A1 = 8.74 x 10\8\ ft\2\
    (2) The spreading formula is based on the theoretical condition that 
the oil will spread uniformly in all directions forming a circle. In 
reality, the outfall of the discharge will direct the oil to the surface 
of the water where it intersects the shoreline. Although the oil will 
not spread uniformly in all directions, it is assumed that the discharge 
will spread from the shoreline into a semi-circle (this assumption does 
not account for winds or wave action).
    (3) The area of a circle= r\2\
    (4) To account for the assumption that oil will spread in a semi-
circular shape, the area of a circle is divided by 2 and is designated 
as A2.

A2 = ( r\2\)/2
Solving for the radius, r, using the relationship A1 = 
          A2: 8.74 x 10\8\ ft\2\ = (\2\)/2
Therefore, r = 23,586 ft
r = 23,586 ft / 5,280 ft/mile = 4.5 miles
Assuming a 20 knot wind under storm conditions:
1 knot = 1.15 miles/hour
20 knots x 1.15 miles/hour/knot = 23 miles/hr
Assuming that the oil slick moves at 3 percent of the wind's speed: \3\
---------------------------------------------------------------------------

    \3\ Oil Spill Prevention & Control. National Spill Control School, 
Corpus Christi State University, Thirteenth Edition, May 1990.
---------------------------------------------------------------------------

23 miles/hour x 0.03 = 0.69 miles/hour

    (5) To estimate the distance that the oil will travel, use the times 
required for response resources to arrive at different geographic 
locations as shown in Table 3 of this attachment.

For example:
For Higher Volume Port Areas: 15 hrs x 0.69 miles/hr = 10.4 miles
For Great Lakes and all other areas: 27 hrs x 0.69 miles/hr = 18.6 miles

    (6) The total distance that the oil will travel from the point of 
discharge, including the distance due to spreading, is calculated as 
follows:

Higher Volume Port Areas: d = 10.4 + 4.5 miles or approximately 15 miles
Great Lakes and all other areas: d = 18.6 + 4.5 miles or approximately 
          23 miles

               4.0 Oil Transport on Tidal-Influence Areas

    4.1 The planning distance method for tidal influence navigable water 
is based on worst case discharges of persistent and non-persistent oils. 
Persistent oils are of primary concern because they can potentially 
cause harm over a greater distance. For persistent oils discharged into 
tidal waters, the planning distance is 15 miles from the facility down 
current during ebb tide and to the point of maximum tidal influence or 
15 miles, whichever is less, during flood tide.
    4.2 For non-persistent oils discharged into tidal waters, the 
planning distance is 5 miles from the facility down current during ebb 
tide and to the point of maximum tidal influence or 5 miles, whichever 
is less, during flood tide.
    4.3 Example of Determining the Planning Distance for Two Types of 
Navigable Water Conditions. Below is an example of how to determine the 
proper planning distance when a facility could impact two types of 
navigable water conditions: moving water and tidal water.
    (1) Facility X stores persistent oil and is located downstream from 
locks along a slow moving river which is affected by tides. The river 
velocity, v, is determined to be 0.5 feet/second from the Chezy-Manning 
equation used to calculate oil transport on moving navigable waters. The 
specified time interval, t, obtained from Table 3 of this attachment for 
river areas is 27 hours. Therefore, solving for the planning distance, 
d:

d = v x t x c
d = (0.5 ft/sec) x (27 hours) x (0.68 secmile/hrft)
d = 9.18 miles.

    (2) However, the planning distance for maximum tidal influence down 
current during ebb tide is 15 miles, which is greater than the 
calculated 9.18 miles. Therefore, 15 miles downstream is the appropriate 
planning distance for this facility.

                       5.0 Oil Transport Over Land

    5.1 Facility owners or operators must evaluate the potential for oil 
to be transported over land to navigable waters of the United States. 
The owner or operator must evaluate the likelihood that portions of a 
worst case discharge would reach navigable

[[Page 68]]

waters via open channel flow or from sheet flow across the land, or be 
prevented from reaching navigable waters when trapped in natural or man-
made depressions excluding secondary containment structures.
    5.2 As discharged oil travels over land, it may enter a storm drain 
or open concrete channel intended for drainage. It is assumed that once 
oil reaches such an inlet, it will flow into the receiving navigable 
water. During a storm event, it is highly probable that the oil will 
either flow into the drainage structures or follow the natural contours 
of the land and flow into the navigable water. Expected minimum and 
maximum velocities are provided as examples of open concrete channel and 
pipe flow. The ranges listed below reflect minimum and maximum 
velocities used as design criteria. \4\ The calculation below 
demonstrates that the time required for oil to travel through a storm 
drain or open concrete channel to navigable water is negligible and can 
be considered instantaneous. The velocities are:
---------------------------------------------------------------------------

    \4\ The design velocities were obtained from Howard County, Maryland 
Department of Public Works' Storm Drainage Design Manual.
---------------------------------------------------------------------------

For open concrete channels:
maximum velocity = 25 feet per second
minimum velocity = 3 feet per second
For storm drains:
maximum velocity = 25 feet per second
minimum velocity = 2 feet per second

    5.3 Assuming a length of 0.5 mile from the point of discharge 
through an open concrete channel or concrete storm drain to a navigable 
water, the travel times (distance/velocity) are:

1.8 minutes at a velocity of 25 feet per second
14.7 minutes at a velocity of 3 feet per second
22.0 minutes for at a velocity of 2 feet per second

    5.4 The distances that shall be considered to determine the planning 
distance are illustrated in Figure C-I of this attachment. The relevant 
distances can be described as follows:

D1 = Distance from the nearest opportunity for discharge, X1, 
          to a storm drain or an open concrete channel leading to 
          navigable water.
D2 = Distance through the storm drain or open concrete channel to 
          navigable water.
D3 = Distance downstream from the outfall within which fish and wildlife 
          and sensitive environments could be injured or a public 
          drinking water intake would be shut down as determined by the 
          planning distance formula.
D4 = Distance from the nearest opportunity for discharge, X2, 
          to fish and wildlife and sensitive environments not bordering 
          navigable water.

    5.5 A facility owner or operator whose nearest opportunity for 
discharge is located within 0.5 mile of a navigable water must complete 
the planning distance calculation (D3) for the type of navigable water 
near the facility or use a comparable formula.
    5.6 A facility that is located at a distance greater than 0.5 mile 
from a navigable water must also calculate a planning distance (D3) if 
it is in close proximity (i.e., D1 is less than 0.5 mile and other 
factors are conducive to oil travel over land) to storm drains that flow 
to navigable waters. Factors to be considered in assessing oil transport 
over land to storm drains shall include the topography of the 
surrounding area, drainage patterns, man-made barriers (excluding 
secondary containment structures), and soil distribution and porosity. 
Storm drains or concrete drainage channels that are located in close 
proximity to the facility can provide a direct pathway to navigable 
waters, regardless of the length of the drainage pipe. If D1 is less 
than or equal to 0.5 mile, a discharge from the facility could pose 
substantial harm because the time to travel the distance from the storm 
drain to the navigable water (D2) is virtually instantaneous.
    5.7 A facility's proximity to fish and wildlife and sensitive 
environments not bordering a navigable water, as depicted as D4 in 
Figure C-I of this attachment, must also be considered, regardless of 
the distance from the facility to navigable waters. Factors to be 
considered in assessing oil transport over land to fish and wildlife and 
sensitive environments should include the topography of the surrounding 
area, drainage patterns, man-made barriers (excluding secondary 
containment structures), and soil distribution and porosity.
    5.8 If a facility is not found to pose substantial harm to fish and 
wildlife and sensitive environments not bordering navigable waters via 
oil transport on land, then supporting documentation should be 
maintained at the facility. However, such documentation should be 
submitted with the response plan if a facility is found to pose 
substantial harm.

  Sec. Appendix D to Part 112--Determination of a Worst Case Discharge 
                             Planning Volume

                            1.0 Instructions

    1.1 An owner or operator is required to complete this worksheet if 
the facility meets the criteria, as presented in appendix C to this 
part, or it is determined by the RA that the facility could cause 
substantial harm to the environment. The calculation of a worst case 
discharge planning volume is used for emergency planning purposes, and 
is required in 40 CFR 112.20 for facility owners or operators who must 
prepare a response plan. When planning for the amount of resources and 
equipment necessary to respond to the worst case discharge planning 
volume, adverse weather conditions must be taken into consideration. An 
owner or operator is required to determine the facility's worst case 
discharge planning volume from either part A of this appendix for an 
onshore storage facility, or part B of this appendix for an onshore 
production facility. The worksheet considers the provision of adequate 
secondary containment at a facility.
    1.2 For onshore storage facilities and production facilities, 
permanently manifolded oil storage tanks are defined as tanks that are 
designed, installed, and/or operated in such a manner that the multiple 
tanks function as one storage unit (i.e., multiple tank volumes are 
equalized). In a worst case discharge scenario, a single failure could 
cause the discharge of the contents of more than one tank. The owner or 
operator must provide evidence in the response plan that tanks with 
common piping or piping systems are not operated as one unit. If such 
evidence is provided and is acceptable to the RA, the worst case 
discharge planning volume would be based on the capacity of the largest 
oil storage tank within a common secondary containment area or the 
largest oil storage tank within a single secondary containment area, 
whichever is greater. For permanently manifolded tanks that function as 
one oil storage unit, the worst case discharge planning volume would be 
based on the combined oil storage capacity of all manifolded tanks or 
the capacity of the largest single oil storage tank within a secondary 
containment area, whichever is greater. For purposes of this rule, 
permanently manifolded tanks that are separated by internal divisions 
for each tank are considered to be single tanks and individual 
manifolded tank volumes are not combined.
    1.3 For production facilities, the presence of exploratory wells, 
production wells, and oil storage tanks must be considered in the 
calculation. Part B of this appendix takes these additional factors into 
consideration and provides steps for their inclusion in the total worst 
case discharge planning volume. Onshore oil production facilities may 
include all wells, flowlines, separation equipment, storage facilities, 
gathering lines, and auxiliary non-transportation-related equipment and 
facilities in a single geographical oil or gas field operated by a 
single operator. Although a potential worst case discharge planning 
volume is calculated within each section of the worksheet, the final 
worst case amount depends on the risk parameter that results in the 
greatest volume.
    1.4 Marine transportation-related transfer facilities that contain 
fixed aboveground onshore structures used for bulk oil storage are 
jointly regulated by EPA and the U.S. Coast Guard (USCG), and are termed 
``complexes.'' Because the USCG also requires response plans from 
transportation-related facilities to address a worst case discharge of 
oil, a separate calculation for the worst case discharge planning volume 
for USCG-related facilities is included in the USCG IFR (see appendix E 
to this part, section 13, for availability). All complexes that are 
jointly regulated by EPA and the USCG must compare both calculations for 
worst case discharge planning volume derived by using the EPA and USCG 
methodologies and plan for whichever volume is greater.

    \1\ ``Storage facilities'' represent all facilities subject to this 
part, excluding oil production facilities.
---------------------------------------------------------------------------

    Part A of this worksheet is to be completed by the owner or operator 
of an SPCC-regulated facility (excluding oil production facilities) if 
the facility meets the criteria as presented in appendix C to this part, 
or if it is determined by the RA that the facility could cause 
substantial harm to the environment. If you are the owner or operator of 
a production facility, please proceed to part B of this worksheet.

                       A.1 SINGLE-TANK FACILITIES

    For facilities containing only one aboveground oil storage tank, the 
worst case discharge planning volume equals the capacity of the oil 
storage tank. If adequate secondary containment (sufficiently large to 
contain the capacity of the aboveground oil storage tank plus sufficient 
freeboard to allow for precipitation) exists for the oil storage tank, 
multiply the capacity of the tank by 0.8.

                          PRODUCTION FACILITIES

    Part B of this worksheet is to be completed by the owner or operator 
of an SPCC-regulated oil production facility if the facility meets the 
criteria presented in appendix C to this part, or if it is determined by 
the RA that the facility could cause substantial harm. A production 
facility consists of all wells (producing and exploratory) and related 
equipment in a single geographical oil or gas field operated by a single 
operator.

                       B.1 SINGLE-TANK FACILITIES

    B.1.1 For facilities containing only one aboveground oil storage 
tank, the worst case discharge planning volume equals the capacity of 
the aboveground oil storage tank plus the production volume of the well 
with the highest output at the facility. If adequate secondary 
containment (sufficiently large to contain the capacity of the 
aboveground oil storage tank plus sufficient freeboard to allow for 
precipitation) exists for the storage tank, multiply the capacity of the 
tank by 0.8.
    B.1.2 For facilities with production wells producing by pumping, if 
the rate of the well with the highest output is known and the number of 
days the facility is unattended can be predicted, then the production 
volume is equal to the pumping rate of the well multiplied by the 
greatest number of days the facility is unattended.
    B.1.3 If the pumping rate of the well with the highest output is 
estimated or the maximum number of days the facility is unattended is 
estimated, then the production volume is determined from the pumping 
rate of the well multiplied by 1.5 times the greatest number of days 
that the facility has been or is expected to be unattended.
    B.1.4 Attachment D-1 to this appendix provides methods for 
calculating the production volume for exploratory wells and production 
wells producing under pressure.

           B.2 SECONDARY CONTAINMENT--MULTIPLE-TANK FACILITIES

    Are all aboveground oil storage tanks or groups of aboveground oil 
storage tanks at the facility without adequate secondary containment?

------ (Y/N)

    B.2.1 If the answer is yes, the final worst case volume equals the 
total aboveground oil storage capacity without adequate secondary 
containment plus the production volume of the well with the highest 
output at the facility.
    (1) For facilities with production wells producing by pumping, if 
the rate of the well with the highest output is known and the number of 
days the facility is unattended can be predicted, then the production 
volume is equal to the pumping rate of the well multiplied by the 
greatest number of days the facility is unattended.
    (2) If the pumping rate of the well with the highest output is 
estimated or the maximum number of days the facility is unattended is 
estimated, then the production volume is determined from the pumping 
rate of the well multiplied by 1.5 times the greatest number of days 
that the facility has been or is expected to be unattended.

the production volumes for exploratory wells and production wells 
producing under pressure.

    B.2.2 If the answer is no, calculate the total aboveground oil 
storage capacity of tanks without adequate secondary containment. If all 
aboveground oil storage tanks or groups of aboveground oil storage tanks 
at the facility have adequate secondary containment, ENTER ``0'' (zero).

-------- GAL

    B.2.3 Calculate the capacity of the largest single aboveground oil 
storage tank within an adequate secondary containment area or the 
combined capacity of a group of aboveground oil storage tanks 
permanently manifolded together, whichever is greater, plus the 
production volume of the well with the highest output, PLUS THE VOLUME 
FROM QUESTION B.2.2. Attachment D-1 provides methods for calculating the 
production volumes for exploratory wells and production wells producing 
under pressure.

 Attachment D-I--Methods To Calculate Production Volumes for Production 
 Facilities With Exploratory Wells or Production Wells Producing Under 
                                Pressure

                            1.0 Introduction

    The owner or operator of a production facility with exploratory 
wells or production wells producing under pressure shall compare the 
well rate of the highest output well (rate of well), in barrels per day, 
to the ability of response equipment and personnel to recover the volume 
of oil that could be discharged (rate of recovery), in barrels per day. 
The result of this comparison will determine the method used to 
calculate the production volume for the production facility. This 
production volume is to be used to calculate the worst case discharge 
planning volume in part B of this appendix.

                       2.0 Description of Methods

    2.1 Method A
    If the well rate would overwhelm the response efforts (i.e., rate of 
well/rate of recovery =1), then the production volume would 
be the 30-day forecasted well rate for a well 10,000 feet deep or less, 
or the 45-day forecasted well rate for a well deeper than 10,000 feet.
    (1) For wells 10,000 feet deep or less:
Production volume = 30 days x rate of well.
    (2) For wells deeper than 10,000 feet:
Production volume = 45 days x rate of well.
    2.2 Method B
    2.2.1 If the rate of recovery would be greater than the well rate 
(i.e., rate of well/rate of recovery <1), then the production volume 
would equal the sum of two terms:

Production volume = discharge volume1 + discharge 
          volume2
    2.2.2 The first term represents the volume of the oil discharged 
from the well between the time of the blowout and the time the response 
resources are on scene and recovering oil (discharge 
volume1).

Discharge volume1 = (days unattended + days to respond) x 
          (rate of well)

    2.2.3 The second term represents the volume of oil discharged from 
the well after the response resources begin operating until the 
discharge is stopped, adjusted for the recovery rate of the response 
resources (discharge volume2).
    (1) For wells 10,000 feet deep or less:
Discharge volume2 = [30 days-(days unattended + days to 
          respond)] x (rate of well) x (rate of well/rate of recovery)
    (2) For wells deeper than 10,000 feet:
Discharge volume2 = [45 days-(days unattended + days to 
          respond)] x (rate of well) x (rate of well/rate of recovery)

                               3.0 Example

    3.1 A facility consists of two production wells producing under 
pressure, which are both less than 10,000 feet deep. The well rate of 
well A is 5 barrels per day, and the well rate of well B is 10 barrels 
per day. The facility is unattended for a maximum of 7 days. The 
facility operator estimates that it will take 2 days to have response 
equipment and personnel on scene and responding to a blowout, and that 
the projected rate of recovery will be 20 barrels per day.
    (1) First, the facility operator determines that the highest output 
well is well B. The facility operator calculates the ratio of the rate 
of well to the rate of recovery:

10 barrels per day/20 barrels per day = 0.5 Because the ratio is less 
          than one, the facility operator will use Method B to calculate 
          the production volume.

    (2) The first term of the equation is:

Discharge volume1 = (7 days + 2 days) x (10 barrels per day) 
          = 90 barrels

    (3) The second term of the equation is:

Discharge volume2 = [30 days--(7 days + 2 days)] x (10 
          barrels per day) x (0.5) = 105 barrels

    (4) Therefore, the production volume is:

Production volume = 90 barrels + 105 barrels = 195 barrels


[[Page 73]]


    3.2 If the recovery rate was 5 barrels per day, the ratio of rate of 
well to rate of recovery would be 2, so the facility operator would use 
Method A. The production volume would have been:

30 days x 10 barrels per day = 300 barrels

 Sec. Appendix E to Part 112--Determination and Evaluation of Required 
             Response Resources for Facility Response Plans

                       1.0 Purpose and Definitions

    1.1 The purpose of this appendix is to describe the procedures to 
identify response resources to meet the requirements of Sec. 112.20. To 
identify response resources to meet the facility response plan 
requirements of 40 CFR 112.20(h), owners or operators shall follow this 
appendix or, where not appropriate, shall clearly demonstrate in the 
response plan why use of this appendix is not appropriate at the 
facility and make comparable arrangements for response resources.
    1.2 Definitions.
    1.2.1 Animal fat means a non-petroleum oil, fat, or grease of 
animal, fish, or marine mammal origin. Animal fats are further 
classified based on specific gravity as follows:
    (1) Group A--specific gravity less than 0.8.
    (2) Group B--specific gravity equal to or greater than 0.8 and less 
than 1.0.
    (3) Group C--specific gravity equal to or greater than 1.0.
    1.2.2 Nearshore is an operating area defined as extending seaward 12 
miles from the boundary lines defined in 46 CFR part 7, except in the 
Gulf of Mexico. In the Gulf of Mexico, it means the area extending 12 
miles from the line of demarcation (COLREG lines) defined in 49 CFR 
80.740 and 80.850.
    1.2.3 Non-persistent oils or Group 1 oils include:
    (1) A petroleum-based oil that, at the time of shipment, consists of 
hydrocarbon fractions:
    (A) At least 50 percent of which by volume, distill at a temperature 
of 340 degrees C (645 degrees F); and
    (B) At least 95 percent of which by volume, distill at a temperature 
of 370 degrees C (700 degrees F); and
    (2) A non-petroleum oil, other than an animal fat or vegetable oil, 
with a specific gravity less than 0.8.
    1.2.4 Non-petroleum oil means oil of any kind that is not petroleum-
based, including but not limited to: fats, oils, and greases of animal, 
fish, or marine mammal origin; and vegetable oils, including oils from 
seeds, nuts, fruits, and kernels.
    1.2.5 Ocean means the nearshore area.
    1.2.6 Operating area means Rivers and Canals, Inland, Nearshore, and 
Great Lakes geographic location(s) in which a facility is handling, 
storing, or transporting oil.
    1.2.7 Operating environment means Rivers and Canals, Inland, Great 
Lakes, or Ocean. These terms are used to define the conditions in which 
response equipment is designed to function.
    1.2.8 Persistent oils include:
    (1) A petroleum-based oil that does not meet the distillation 
criteria for a non-persistent oil. Persistent oils are further 
classified based on specific gravity as follows:
    (A) Group 2--specific gravity less than 0.85;
    (B) Group 3--specific gravity equal to or greater than 0.85 and less 
than 0.95;
    (C) Group 4--specific gravity equal to or greater than 0.95 and less 
than 1.0; or
    (D) Group 5--specific gravity equal to or greater than 1.0.

    1.2.10 Other definitions are included in Sec. 112.2, section 1.1 of 
appendix C, and section 3.0 of appendix F.

                 2.0 Equipment Operability and Readiness

    2.1 All equipment identified in a response plan must be designed to 
operate in the conditions expected in the facility's geographic area 
(i.e., operating environment). These conditions vary widely based on 
location and season. Therefore, it is difficult to identify a single 
stockpile of response equipment that will function effectively in each 
geographic location (i.e., operating area).
    2.2 Facilities handling, storing, or transporting oil in more than 
one operating environment as indicated in Table 1 of this appendix must 
identify equipment capable of successfully functioning in each operating 
environment.

[[Page 74]]

    2.3 When identifying equipment for the response plan (based on the 
use of this appendix), a facility owner or operator must consider the 
inherent limitations of the operability of equipment components and 
response systems. The criteria in Table 1 of this appendix shall be used 
to evaluate the operability in a given environment. These criteria 
reflect the general conditions in certain operating environments.
    2.3.1 The Regional Administrator may require documentation that the 
boom identified in a facility response plan meets the criteria in Table 
1 of this appendix. Absent acceptable documentation, the Regional 
Administrator may require that the boom be tested to demonstrate that it 
meets the criteria in Table 1 of this appendix. Testing must be in 
accordance with ASTM F 715, ASTM F 989, or other tests approved by EPA 
as deemed appropriate (see appendix E to this part, section 13, for 
general availability of documents).
    2.4 Table 1 of this appendix lists criteria for oil recovery devices 
and boom. All other equipment necessary to sustain or support response 
operations in an operating environment must be designed to function in 
the same conditions. For example, boats that deploy or support skimmers 
or boom must be capable of being safely operated in the significant wave 
heights listed for the applicable operating environment.
    2.5 A facility owner or operator shall refer to the applicable Area 
Contingency Plan (ACP), where available, to determine if ice, debris, 
and weather-related visibility are significant factors to evaluate the 
operability of equipment. The ACP may also identify the average 
temperature ranges expected in the facility's operating area. All 
equipment identified in a response plan must be designed to operate 
within those conditions or ranges.
    2.6 This appendix provides information on response resource 
mobilization and response times. The distance of the facility from the 
storage location of the response resources must be used to determine 
whether the resources can arrive on-scene within the stated time. A 
facility owner or operator shall include the time for notification, 
mobilization, and travel of resources identified to meet the medium and 
Tier 1 worst case discharge requirements identified in sections 4.3 and 
9.3 of this appendix (for medium discharges) and section 5.3 of this 
appendix (for worst case discharges). The facility owner or operator 
must plan for notification and mobilization of Tier 2 and 3 response 
resources as necessary to meet the requirements for arrival on-scene in 
accordance with section 5.3 of this appendix. An on-water speed of 5 
knots and a land speed of 35 miles per hour is assumed, unless the 
facility owner or operator can demonstrate otherwise.
    2.7 In identifying equipment, the facility owner or operator shall 
list the storage location, quantity, and manufacturer's make and model. 
For oil recovery devices, the effective daily recovery capacity, as 
determined using section 6 of this appendix, must be included. For boom, 
the overall boom height (draft and freeboard) shall be included. A 
facility owner or operator is responsible for ensuring that the 
identified boom has compatible connectors.

   3.0 Determining Response Resources Required for Small Discharges--
    Petroleum Oils and Non-Petroleum Oils Other Than Animal Fats and 
                             Vegetable Oils

    3.1 A facility owner or operator shall identify sufficient response 
resources available, by contract or other approved means as described in 
Sec. 112.2, to respond to a small discharge. A small discharge is 
defined as any discharge volume less than or equal to 2,100 gallons, but 
not to exceed the calculated worst case discharge. The equipment must be 
designed to function in the operating environment at the point of 
expected use.
    3.2 Complexes that are regulated by EPA and the United States Coast 
Guard (USCG) must also consider planning quantities for the 
transportation-related transfer portion of the facility.
    3.2.1 Petroleum oils. The USCG planning level that corresponds to 
EPA's ``small discharge'' is termed ``the average most probable 
discharge.'' A USCG rule found at 33 CFR 154.1020 defines ``the average 
most probable discharge'' as the lesser of 50 barrels (2,100 gallons) or 
1 percent of the volume of the worst case discharge. Owners or operators 
of complexes that handle, store, or transport petroleum oils must 
compare oil discharge volumes for a small discharge and an average most 
probable discharge, and plan for whichever quantity is greater.
    3.2.2 Non-petroleum oils other than animal fats and vegetable oils. 
Owners or operators of complexes that handle, store, or transport non-
petroleum oils other than animal fats and vegetable oils must plan for 
oil discharge volumes for a small discharge. There is no USCG planning 
level that directly corresponds to EPA's ``small discharge.'' However, 
the USCG (at 33 CFR 154.545) has requirements to identify equipment to 
contain oil resulting from an operational discharge.
    3.3 The response resources shall, as appropriate, include:
    3.3.1 One thousand feet of containment boom (or, for complexes with 
marine transfer components, 1,000 feet of containment boom or two times 
the length of the largest vessel that regularly conducts oil transfers 
to or from the facility, whichever is greater), and a means of deploying 
it within 1 hour of the discovery of a discharge;
    3.3.2 Oil recovery devices with an effective daily recovery capacity 
equal to the amount of oil discharged in a small discharge or greater 
which is available at the

[[Page 75]]

facility within 2 hours of the detection of an oil discharge; and
    3.3.3 Oil storage capacity for recovered oily material indicated in 
section 12.2 of this appendix.

   4.0 Determining Response Resources Required for Medium Discharges--
    Petroleum Oils and Non-Petroleum Oils Other Than Animal Fats and 
                             Vegetable Oils

    4.1 A facility owner or operator shall identify sufficient response 
resources available, by contract or other approved means as described in 
Sec. 112.2, to respond to a medium discharge of oil for that facility. 
This will require response resources capable of containing and 
collecting up to 36,000 gallons of oil or 10 percent of the worst case 
discharge, whichever is less. All equipment identified must be designed 
to operate in the applicable operating environment specified in Table 1 
of this appendix.
    4.2 Complexes that are regulated by EPA and the USCG must also 
consider planning quantities for the transportation-related transfer 
portion of the facility.
    4.2.1 Petroleum oils. The USCG planning level that corresponds to 
EPA's ``medium discharge'' is termed ``the maximum most probable 
discharge.'' The USCG rule found at 33 CFR part 154 defines ``the 
maximum most probable discharge'' as a discharge of 1,200 barrels 
(50,400 gallons) or 10 percent of the worst case discharge, whichever is 
less. Owners or operators of complexes that handle, store, or transport 
petroleum oils must compare calculated discharge volumes for a medium 
discharge and a maximum most probable discharge, and plan for whichever 
quantity is greater.
    4.2.2 Non-petroleum oils other than animal fats and vegetable oils. 
Owners or operators of complexes that handle, store, or transport non-
petroleum oils other than animal fats and vegetable oils must plan for 
oil discharge volumes for a medium discharge. For non-petroleum oils, 
there is no USCG planning level that directly corresponds to EPA's 
``medium discharge.''
    4.3 Oil recovery devices identified to meet the applicable medium 
discharge volume planning criteria must be located such that they are 
capable of arriving on-scene within 6 hours in higher volume port areas 
and the Great Lakes and within 12 hours in all other areas. Higher 
volume port areas and Great Lakes areas are defined in section 1.1 of 
appendix C to this part.
    4.4 Because rapid control, containment, and removal of oil are 
critical to reduce discharge impact, the owner or operator must 
determine response resources using an effective daily recovery capacity 
for oil recovery devices equal to 50 percent of the planning volume 
applicable for the facility as determined in section 4.1 of this 
appendix. The effective daily recovery capacity for oil recovery devices 
identified in the plan must be determined using the criteria in section 
6 of this appendix.
    4.5 In addition to oil recovery capacity, the plan shall, as 
appropriate, identify sufficient quantity of containment boom available, 
by contract or other approved means as described in Sec. 112.2, to 
arrive within the required response times for oil collection and 
containment and for protection of fish and wildlife and sensitive 
environments. For further description of fish and wildlife and sensitive 
environments, see Appendices I, II, and III to DOC/NOAA's ``Guidance for 
Facility and Vessel Response Plans: Fish and Wildlife and Sensitive 
Environments'' (see appendix E to this part, section 13, for 
availability) and the applicable ACP. Although 40 CFR part 112 does not 
set required quantities of boom for oil collection and containment, the 
response plan shall identify and ensure, by contract or other approved 
means as described in Sec. 112.2, the availability of the quantity of 
boom identified in the plan for this purpose.
    4.6 The plan must indicate the availability of temporary storage 
capacity to meet section 12.2 of this appendix. If available storage 
capacity is insufficient to meet this level, then the effective daily 
recovery capacity must be derated (downgraded) to the limits of the 
available storage capacity.
    4.7 The following is an example of a medium discharge volume 
planning calculation for equipment identification in a higher volume 
port area: The facility's largest aboveground storage tank volume is 
840,000 gallons. Ten percent of this capacity is 84,000 gallons. Because 
10 percent of the facility's largest tank, or 84,000 gallons, is greater 
than 36,000 gallons, 36,000 gallons is used as the planning volume. The 
effective daily recovery capacity is 50 percent of the planning volume, 
or 18,000 gallons per day. The ability of oil recovery devices to meet 
this capacity must be calculated using the procedures in section 6 of 
this appendix. Temporary storage capacity available on-scene must equal 
twice the daily recovery capacity as indicated in section 12.2 of this 
appendix, or 36,000 gallons per day. This is the information the 
facility owner or operator must use to identify and ensure the 
availability of the required response resources, by contract or other 
approved means as described in Sec. 112.2. The facility owner shall 
also identify how much boom is available for use.

5.0 Determining Response Resources Required for the Worst Case Discharge 
                    to the Maximum Extent Practicable

    5.1 A facility owner or operator shall identify and ensure the 
availability of, by

[[Page 76]]

contract or other approved means as described in Sec. 112.2, sufficient 
response resources to respond to the worst case discharge of oil to the 
maximum extent practicable. Sections 7 and 10 of this appendix describe 
the method to determine the necessary response resources. Worksheets are 
provided as Attachments E-1 and E-2 at the end of this appendix to 
simplify the procedures involved in calculating the planning volume for 
response resources for the worst case discharge.
    5.2 Complexes that are regulated by EPA and the USCG must also 
consider planning for the worst case discharge at the transportation-
related portion of the facility. The USCG requires that transportation-
related facility owners or operators use a different calculation for the 
worst case discharge in the revisions to 33 CFR part 154. Owners or 
operators of complex facilities that are regulated by EPA and the USCG 
must compare both calculations of worst case discharge derived by EPA 
and the USCG and plan for whichever volume is greater.
    5.3 Oil discharge response resources identified in the response plan 
and available, by contract or other approved means as described in Sec. 
112.2, to meet the applicable worst case discharge planning volume must 
be located such that they are capable of arriving at the scene of a 
discharge within the times specified for the applicable response tier 
listed as follows

----------------------------------------------------------------------------------------------------------------
                                                                            Tier 1 (in   Tier 2 (in   Tier 3 (in
                                                                              hours)       hours)       hours)
----------------------------------------------------------------------------------------------------------------
Higher volume port areas.................................................            6           30           54
Great Lakes..............................................................           12           36           60
All other river and canal, inland, and nearshore areas...................           12           36           60
----------------------------------------------------------------------------------------------------------------

    The three levels of response tiers apply to the amount of time in 
which facility owners or operators must plan for response resources to 
arrive at the scene of a discharge to respond to the worst case 
discharge planning volume. For example, at a worst case discharge in an 
inland area, the first tier of response resources (i.e., that amount of 
on-water and shoreline cleanup capacity necessary to respond to the 
fraction of the worst case discharge as indicated through the series of 
steps described in sections 7.2 and 7.3 or sections 10.2 and 10.3 of 
this appendix) would arrive at the scene of the discharge within 12 
hours; the second tier of response resources would arrive within 36 
hours; and the third tier of response resources would arrive within 60 
hours.
    5.4 The effective daily recovery capacity for oil recovery devices 
identified in the response plan must be determined using the criteria in 
section 6 of this appendix. A facility owner or operator shall identify 
the storage locations of all response resources used for each tier. The 
owner or operator of a facility whose required daily recovery capacity 
exceeds the applicable contracting caps in Table 5 of this appendix 
shall, as appropriate, identify sources of additional equipment, their 
location, and the arrangements made to obtain this equipment during a 
response. The owner or operator of a facility whose calculated planning 
volume exceeds the applicable contracting caps in Table 5 of this 
appendix shall, as appropriate, identify sources of additional equipment 
equal to twice the cap listed in Tier 3 or the amount necessary to reach 
the calculated planning volume, whichever is lower. The resources 
identified above the cap shall be capable of arriving on-scene not later 
than the Tier 3 response times in section 5.3 of this appendix. No 
contract is required. While general listings of available response 
equipment may be used to identify additional sources (i.e., ``public'' 
resources vs. ``private'' resources), the response plan shall identify 
the specific sources, locations, and quantities of equipment that a 
facility owner or operator has considered in his or her planning. When 
listing USCG-classified oil spill removal organization(s) that have 
sufficient removal capacity to recover the volume above the response 
capacity cap for the specific facility, as specified in Table 5 of this 
appendix, it is not necessary to list specific quantities of equipment.
    5.5 A facility owner or operator shall identify the availability of 
temporary storage capacity to meet section 12.2 of this appendix. If 
available storage capacity is insufficient, then the effective daily 
recovery capacity must be derated (downgraded) to the limits of the 
available storage capacity.
    5.6 When selecting response resources necessary to meet the response 
plan requirements, the facility owner or operator shall, as appropriate, 
ensure that a portion of those resources is capable of being used in 
close-to-shore response activities in shallow water. For any EPA-
regulated facility that is required to plan for response in shallow 
water, at least 20 percent of the on-water response equipment identified 
for the applicable operating area shall, as appropriate, be capable of 
operating in water of 6 feet or less depth.
    5.7 In addition to oil spill recovery devices, a facility owner or 
operator shall identify sufficient quantities of boom that are 
available, by contract or other approved means as described in Sec. 
112.2, to arrive on-

[[Page 77]]

scene within the specified response times for oil containment and 
collection. The specific quantity of boom required for collection and 
containment will depend on the facility-specific information and 
response strategies employed. A facility owner or operator shall, as 
appropriate, also identify sufficient quantities of oil containment boom 
to protect fish and wildlife and sensitive environments. For further 
description of fish and wildlife and sensitive environments, see 
Appendices I, II, and III to DOC/NOAA's ``Guidance for Facility and 
Vessel Response Plans: Fish and Wildlife and Sensitive Environments'' 
(see appendix E to this part, section 13, for availability), and the 
applicable ACP. Refer to this guidance document for the number of days 
and geographic areas (i.e., operating environments) specified in Table 2 
and Table 6 of this appendix.
    5.8 A facility owner or operator shall also identify, by contract or 
other approved means as described in Sec. 112.2, the availability of an 
oil spill removal organization(s) (as described in Sec. 112.2) capable 
of responding to a shoreline cleanup operation involving the calculated 
volume of oil and emulsified oil that might impact the affected 
shoreline. The volume of oil that shall, as appropriate, be planned for 
is calculated through the application of factors contained in Tables 2, 
3, 6, and 7 of this appendix. The volume calculated from these tables is 
intended to assist the facility owner or operator to identify an oil 
spill removal organization with sufficient resources and expertise.

   6.0 Determining Effective Daily Recovery Capacity for Oil Recovery 
                                 Devices

    6.1 Oil recovery devices identified by a facility owner or operator 
must be identified by the manufacturer, model, and effective daily 
recovery capacity. These capacities must be used to determine whether 
there is sufficient capacity to meet the applicable planning criteria 
for a small discharge, a medium discharge, and a worst case discharge to 
the maximum extent practicable.
    6.2 To determine the effective daily recovery capacity of oil 
recovery devices, the formula listed in section 6.2.1 of this appendix 
shall be used. This formula considers potential limitations due to 
available daylight, weather, sea state, and percentage of emulsified oil 
in the recovered material. The RA may assign a lower efficiency factor 
to equipment listed in a response plan if it is determined that such a 
reduction is warranted.
    6.2.1 The following formula shall be used to calculate the effective 
daily recovery capacity:

R = T x 24 hours x E

where:

R--Effective daily recovery capacity;
T--Throughput rate in barrels per hour (nameplate capacity); and
E--20 percent efficiency factor (or lower factor as determined by the 
          Regional Administrator).

    6.2.2 For those devices in which the pump limits the throughput of 
liquid, throughput rate shall be calculated using the pump capacity.
    6.2.3 For belt or moptype devices, the throughput rate shall be 
calculated using the speed of the belt or mop through the device, 
assumed thickness of oil adhering to or collected by the device, and 
surface area of the belt or mop. For purposes of this calculation, the 
assumed thickness of oil will be \1/4\ inch.
    6.2.4 Facility owners or operators that include oil recovery devices 
whose throughput is not measurable using a pump capacity or belt/mop 
speed may provide information to support an alternative method of 
calculation. This information must be submitted following the procedures 
in section 6.3.2 of this appendix.
    6.3 As an alternative to section 6.2 of this appendix, a facility 
owner or operator may submit adequate evidence that a different 
effective daily recovery capacity should be applied for a specific oil 
recovery device. Adequate evidence is actual verified performance data 
in discharge conditions or tests using American Society of Testing and 
Materials (ASTM) Standard F 631-99, F 808-83 (1999), or an equivalent 
test approved by EPA as deemed appropriate (see Appendix E to this part, 
section 13, for general availability of documents).
    6.3.1 The following formula must be used to calculate the effective 
daily recovery capacity under this alternative:

R = D x U

where:
R--Effective daily recovery capacity;
D--Average Oil Recovery Rate in barrels per hour (Item 26 in F 808-83; 
          Item 13.2.16 in F 631-99; or actual performance data); and
U--Hours per day that equipment can operate under discharge conditions. 
          Ten hours per day must be used unless a facility owner or 
          operator can demonstrate that the recovery operation can be 
          sustained for longer periods.
    6.3.2 A facility owner or operator submitting a response plan shall 
provide data that supports the effective daily recovery capacities for 
the oil recovery devices listed. The following is an example of these 
calculations:
    (1) A weir skimmer identified in a response plan has a 
manufacturer's rated throughput at the pump of 267 gallons per minute 
(gpm).

267 gpm = 381 barrels per hour (bph)
R = 381 bph x 24 hr/day x 0.2 = 1,829 barrels per day


[[Page 78]]


    (2) After testing using ASTM procedures, the skimmer's oil recovery 
rate is determined to be 220 gpm. The facility owner or operator 
identifies sufficient resources available to support operations for 12 
hours per day.

220 gpm = 314 bph
R = 314 bph x 12 hr/day = 3,768 barrels per day

    (3) The facility owner or operator will be able to use the higher 
capacity if sufficient temporary oil storage capacity is available. 
Determination of alternative efficiency factors under section 6.2 of 
this appendix or the acceptability of an alternative effective daily 
recovery capacity under section 6.3 of this appendix will be made by the 
Regional Administrator as deemed appropriate.

 7.0 Calculating Planning Volumes for a Worst Case Discharge--Petroleum 
  Oils and Non-Petroleum Oils Other Than Animal Fats and Vegetable Oils

    7.1 A facility owner or operator shall plan for a response to the 
facility's worst case discharge. The planning for on-water oil recovery 
must take into account a loss of some oil to the environment due to 
evaporative and natural dissipation, potential increases in volume due 
to emulsification, and the potential for deposition of oil on the 
shoreline. The procedures for non-petroleum oils other than animal fats 
and vegetable oils are discussed in section 7.7 of this appendix.
    7.2 The following procedures must be used by a facility owner or 
operator in determining the required on-water oil recovery capacity:
    7.2.1 The following must be determined: the worst case discharge 
volume of oil in the facility; the appropriate group(s) for the types of 
oil handled, stored, or transported at the facility [persistent (Groups 
2, 3, 4, 5) or non-persistent (Group 1)]; and the facility's specific 
operating area. See sections 1.2.3 and 1.2.8 of this appendix for the 
definitions of non-persistent and persistent oils, respectively. 
Facilities that handle, store, or transport oil from different oil 
groups must calculate each group separately, unless the oil group 
constitutes 10 percent or less by volume of the facility's total oil 
storage capacity. This information is to be used with Table 2 of this 
appendix to determine the percentages of the total volume to be used for 
removal capacity planning. Table 2 of this appendix divides the volume 
into three categories: oil lost to the environment; oil deposited on the 
shoreline; and oil available for on-water recovery.
    7.2.2 The on-water oil recovery volume shall, as appropriate, be 
adjusted using the appropriate emulsification factor found in Table 3 of 
this appendix. Facilities that handle, store, or transport oil from 
different petroleum groups must compare the on-water recovery volume for 
each oil group (unless the oil group constitutes 10 percent or less by 
volume of the facility's total storage capacity) and use the calculation 
that results in the largest on-water oil recovery volume to plan for the 
amount of response resources for a worst case discharge.
    7.2.3 The adjusted volume is multiplied by the on-water oil recovery 
resource mobilization factor found in Table 4 of this appendix from the 
appropriate operating area and response tier to determine the total on-
water oil recovery capacity in barrels per day that must be identified 
or contracted to arrive on-scene within the applicable time for each 
response tier. Three tiers are specified. For higher volume port areas, 
the contracted tiers of resources must be located such that they are 
capable of arriving on-scene within 6 hours for Tier 1, 30 hours for 
Tier 2, and 54 hours for Tier 3 of the discovery of an oil discharge. 
For all other rivers and canals, inland, nearshore areas, and the Great 
Lakes, these tiers are 12, 36, and 60 hours.
    7.2.4 The resulting on-water oil recovery capacity in barrels per 
day for each tier is used to identify response resources necessary to 
sustain operations in the applicable operating area. The equipment shall 
be capable of sustaining operations for the time period specified in 
Table 2 of this appendix. The facility owner or operator shall identify 
and ensure the availability, by contract or other approved means as 
described in Sec. 112.2, of sufficient oil spill recovery devices to 
provide the effective daily oil recovery capacity required. If the 
required capacity exceeds the applicable cap specified in Table 5 of 
this appendix, then a facility owner or operator shall ensure, by 
contract or other approved means as described in Sec. 112.2, only for 
the quantity of resources required to meet the cap, but shall identify 
sources of additional resources as indicated in section 5.4 of this 
appendix. The owner or operator of a facility whose planning volume 
exceeded the cap in 1993 must make arrangements to identify and ensure 
the availability, by contract or other approved means as described in 
Sec. 112.2, for additional capacity to be under contract by 1998 or 
2003, as appropriate. For a facility that handles multiple groups of 
oil, the required effective daily recovery capacity for each oil group 
is calculated before applying the cap. The oil group calculation 
resulting in the largest on-water recovery volume must be used to plan 
for the amount of response resources for a worst case discharge, unless 
the oil group comprises 10 percent or less by volume of the facility's 
total oil storage capacity.
    7.3 The procedures discussed in sections 7.3.1-7.3.3 of this 
appendix must be used to calculate the planning volume for identifying 
shoreline cleanup capacity (for Group 1 through Group 4 oils).
    7.3.1 The following must be determined: the worst case discharge 
volume of oil for

[[Page 79]]

the facility; the appropriate group(s) for the types of oil handled, 
stored, or transported at the facility [persistent (Groups 2, 3, or 4) 
or non-persistent (Group 1)]; and the geographic area(s) in which the 
facility operates (i.e., operating areas). For a facility handling, 
storing, or transporting oil from different groups, each group must be 
calculated separately. Using this information, Table 2 of this appendix 
must be used to determine the percentages of the total volume to be used 
for shoreline cleanup resource planning.
    7.3.2 The shoreline cleanup planning volume must be adjusted to 
reflect an emulsification factor using the same procedure as described 
in section 7.2.2 of this appendix.
    7.3.3 The resulting volume shall be used to identify an oil spill 
removal organization with the appropriate shoreline cleanup capability.
    7.4 A response plan must identify response resources with fire 
fighting capability. The owner or operator of a facility that handles, 
stores, or transports Group 1 through Group 4 oils that does not have 
adequate fire fighting resources located at the facility or that cannot 
rely on sufficient local fire fighting resources must identify adequate 
fire fighting resources. The facility owner or operator shall ensure, by 
contract or other approved means as described in Sec. 112.2, the 
availability of these resources. The response plan must also identify an 
individual located at the facility to work with the fire department for 
Group 1 through Group 4 oil fires. This individual shall also verify 
that sufficient well-trained fire fighting resources are available 
within a reasonable response time to a worst case scenario. The 
individual may be the qualified individual identified in the response 
plan or another appropriate individual located at the facility.
    7.5 The following is an example of the procedure described above in 
sections 7.2 and 7.3 of this appendix: A facility with a 270,000 barrel 
(11.3 million gallons) capacity for 6 oil (specific gravity 0.96) is 
located in a higher volume port area. The facility is on a peninsula and 
has docks on both the ocean and bay sides. The facility has four 
aboveground oil storage tanks with a combined total capacity of 80,000 
barrels (3.36 million gallons) and no secondary containment. The 
remaining facility tanks are inside secondary containment structures. 
The largest aboveground oil storage tank (90,000 barrels or 3.78 million 
gallons) has its own secondary containment. Two 50,000 barrel (2.1 
million gallon) tanks (that are not connected by a manifold) are within 
a common secondary containment tank area, which is capable of holding 
100,000 barrels (4.2 million gallons) plus sufficient freeboard.
    7.5.1 The worst case discharge for the facility is calculated by 
adding the capacity of all aboveground oil storage tanks without 
secondary containment (80,000 barrels) plus the capacity of the largest 
aboveground oil storage tank inside secondary containment. The resulting 
worst case discharge volume is 170,000 barrels or 7.14 million gallons.
    7.5.2 Because the requirements for Tiers 1, 2, and 3 for inland and 
nearshore exceed the caps identified in Table 5 of this appendix, the 
facility owner will contract for a response to 10,000 barrels per day 
(bpd) for Tier 1, 20,000 bpd for Tier 2, and 40,000 bpd for Tier 3. 
Resources for the remaining 7,850 bpd for Tier 1, 9,750 bpd for Tier 2, 
and 7,600 bpd for Tier 3 shall be identified but need not be contracted 
for in advance. The facility owner or operator shall, as appropriate, 
also identify or contract for quantities of boom identified in their 
response plan for the protection of fish and wildlife and sensitive 
environments within the area potentially impacted by a worst case 
discharge from the facility. For further description of fish and 
wildlife and sensitive environments, see Appendices I, II, and III to 
DOC/NOAA's ``Guidance for Facility and Vessel Response Plans: Fish and 
Wildlife and Sensitive Environments,'' (see appendix E to this part, 
section 13, for availability) and the applicable ACP. Attachment C-III 
to Appendix C provides a method for calculating a planning distance to 
fish and wildlife and sensitive environments and public drinking water 
intakes that may be impacted in the event of a worst case discharge.
    7.6 The procedures discussed in sections 7.6.1-7.6.3 of this 
appendix must be used to determine appropriate response resources for 
facilities with Group 5 oils.
    7.6.1 The owner or operator of a facility that handles, stores, or 
transports Group 5 oils shall, as appropriate, identify the response 
resources available by contract or other approved means, as described in 
Sec. 112.2. The equipment identified in a response plan shall, as 
appropriate, include:
    (1) Sonar, sampling equipment, or other methods for locating the oil 
on the bottom or suspended in the water column;
    (2) Containment boom, sorbent boom, silt curtains, or other methods 
for containing the oil that may remain floating on the surface or to 
reduce spreading on the bottom;
    (3) Dredges, pumps, or other equipment necessary to recover oil from 
the bottom and shoreline;
    (4) Equipment necessary to assess the impact of such discharges; and
    (5) Other appropriate equipment necessary to respond to a discharge 
involving the type of oil handled, stored,, or transported.
    7.6.2 Response resources identified in a response plan for a 
facility that handles, stores, or transports Group 5 oils under section 
7.6.1 of this appendix shall be capable of being deployed (on site) 
within 24 hours of discovery of a discharge to the area where the 
facility is operating.

[[Page 80]]

    7.6.3 A response plan must identify response resources with fire 
fighting capability. The owner or operator of a facility that handles, 
stores, or transports Group 5 oils that does not have adequate fire 
fighting resources located at the facility or that cannot rely on 
sufficient local fire fighting resources must identify adequate fire 
fighting resources. The facility owner or operator shall ensure, by 
contract or other approved means as described in Sec. 112.2, the 
availability of these resources. The response plan shall also identify 
an individual located at the facility to work with the fire department 
for Group 5 oil fires. This individual shall also verify that sufficient 
well-trained fire fighting resources are available within a reasonable 
response time to respond to a worst case discharge. The individual may 
be the qualified individual identified in the response plan or another 
appropriate individual located at the facility.
    7.7 Non-petroleum oils other than animal fats and vegetable oils. 
The procedures described in sections 7.7.1 through 7.7.5 of this 
appendix must be used to determine appropriate response plan development 
and evaluation criteria for facilities that handle, store, or transport 
non-petroleum oils other than animal fats and vegetable oils. Refer to 
section 11 of this appendix for information on the limitations on the 
use of chemical agents for inland and nearshore areas.
    7.7.1 An owner or operator of a facility that handles, stores, or 
transports non-petroleum oils other than animal fats and vegetable oils 
must provide information in his or her plan that identifies:
    (1) Procedures and strategies for responding to a worst case 
discharge to the maximum extent practicable; and
    (2) Sources of the equipment and supplies necessary to locate, 
recover, and mitigate such a discharge.
    7.7.2 An owner or operator of a facility that handles, stores, or 
transports non-petroleum oils other than animal fats and vegetable oils 
must ensure that any equipment identified in a response plan is capable 
of operating in the conditions expected in the geographic area(s) (i.e., 
operating environments) in which the facility operates using the 
criteria in Table 1 of this appendix. When evaluating the operability of 
equipment, the facility owner or operator must consider limitations that 
are identified in the appropriate ACPs, including:
    (1) Ice conditions;
    (2) Debris;
    (3) Temperature ranges; and
    (4) Weather-related visibility.
    7.7.3 The owner or operator of a facility that handles, stores, or 
transports non-petroleum oils other than animal fats and vegetable oils 
must identify the response resources that are available by contract or 
other approved means, as described in Sec. 112.2. The equipment 
described in the response plan shall, as appropriate, include:
    (1) Containment boom, sorbent boom, or other methods for containing 
oil floating on the surface or to protect shorelines from impact;
    (2) Oil recovery devices appropriate for the type of non-petroleum 
oil carried; and
    (3) Other appropriate equipment necessary to respond to a discharge 
involving the type of oil carried.
    7.7.4 Response resources identified in a response plan according to 
section 7.7.3 of this appendix must be capable of commencing an 
effective on-scene response within the applicable tier response times in 
section 5.3 of this appendix.
    7.7.5 A response plan must identify response resources with fire 
fighting capability. The owner or operator of a facility that handles, 
stores, or transports non-petroleum oils other than animal fats and 
vegetable oils that does not have adequate fire fighting resources 
located at the facility or that cannot rely on sufficient local fire 
fighting resources must identify adequate fire fighting resources. The 
owner or operator shall ensure, by contract or other approved means as 
described in Sec. 112.2, the availability of these resources. The 
response plan must also identify an individual located at the facility 
to work with the fire department for fires of these oils. This 
individual shall also verify that sufficient well-trained fire fighting 
resources are available within a reasonable response time to a worst 
case scenario. The individual may be the qualified individual identified 
in the response plan or another appropriate individual located at the 
facility.

8.0 Determining Response Resources Required for Small Discharges--Animal 
                         Fats and Vegetable Oils

    8.1 A facility owner or operator shall identify sufficient response 
resources available, by contract or other approved means as described in 
Sec. 112.2, to respond to a small discharge of animal fats or vegetable 
oils. A small discharge is defined as any discharge volume less than or 
equal to 2,100 gallons, but not to exceed the calculated worst case 
discharge. The equipment must be designed to function in the operating 
environment at the point of expected use.
    8.2 Complexes that are regulated by EPA and the USCG must also 
consider planning quantities for the marine transportation-related 
portion of the facility.
    8.2.1 The USCG planning level that corresponds to EPA's ``small 
discharge'' is termed ``the average most probable discharge.'' A USCG 
rule found at 33 CFR 154.1020 defines ``the average most probable 
discharge'' as the lesser of 50 barrels (2,100 gallons) or 1 percent of 
the volume of the worst case discharge. Owners or operators of

[[Page 81]]

complexes that handle, store, or transport animal fats and vegetable 
oils must compare oil discharge volumes for a small discharge and an 
average most probable discharge, and plan for whichever quantity is 
greater.
    8.3 The response resources shall, as appropriate, include:
    8.3.1 One thousand feet of containment boom (or, for complexes with 
marine transfer components, 1,000 feet of containment boom or two times 
the length of the largest vessel that regularly conducts oil transfers 
to or from the facility, whichever is greater), and a means of deploying 
it within 1 hour of the discovery of a discharge;
    8.3.2 Oil recovery devices with an effective daily recovery capacity 
equal to the amount of oil discharged in a small discharge or greater 
which is available at the facility within 2 hours of the detection of a 
discharge; and
    8.3.3 Oil storage capacity for recovered oily material indicated in 
section 12.2 of this appendix.

   9.0 Determining Response Resources Required for Medium Discharges--
                     Animal Fats and Vegetable Oils

    9.1 A facility owner or operator shall identify sufficient response 
resources available, by contract or other approved means as described in 
Sec. 112.2, to respond to a medium discharge of animal fats or 
vegetable oils for that facility. This will require response resources 
capable of containing and collecting up to 36,000 gallons of oil or 10 
percent of the worst case discharge, whichever is less. All equipment 
identified must be designed to operate in the applicable operating 
environment specified in Table 1 of this appendix.
    9.2 Complexes that are regulated by EPA and the USCG must also 
consider planning quantities for the transportation-related transfer 
portion of the facility. Owners or operators of complexes that handle, 
store, or transport animal fats or vegetable oils must plan for oil 
discharge volumes for a medium discharge. For non-petroleum oils, there 
is no USCG planning level that directly corresponds to EPA's ``medium 
discharge.'' Although the USCG does not have planning requirements for 
medium discharges, they do have requirements (at 33 CFR 154.545) to 
identify equipment to contain oil resulting from an operational 
discharge.
    9.3 Oil recovery devices identified to meet the applicable medium 
discharge volume planning criteria must be located such that they are 
capable of arriving on-scene within 6 hours in higher volume port areas 
and the Great Lakes and within 12 hours in all other areas. Higher 
volume port areas and Great Lakes areas are defined in section 1.1 of 
appendix C to this part.
    9.4 Because rapid control, containment, and removal of oil are 
critical to reduce discharge impact, the owner or operator must 
determine response resources using an effective daily recovery capacity 
for oil recovery devices equal to 50 percent of the planning volume 
applicable for the facility as determined in section 9.1 of this 
appendix. The effective daily recovery capacity for oil recovery devices 
identified in the plan must be determined using the criteria in section 
6 of this appendix.
    9.5 In addition to oil recovery capacity, the plan shall, as 
appropriate, identify sufficient quantity of containment boom available, 
by contract or other approved means as described in Sec. 112.2, to 
arrive within the required response times for oil collection and 
containment and for protection of fish and wildlife and sensitive 
environments. For further description of fish and wildlife and sensitive 
environments, see Appendices I, II, and III to DOC/NOAA's ``Guidance for 
Facility and Vessel Response Plans: Fish and Wildlife and Sensitive 
Environments'' (59 FR 14713-22, March 29, 1994) and the applicable ACP. 
Although 40 CFR part 112 does not set required quantities of boom for 
oil collection and containment, the response plan shall identify and 
ensure, by contract or other approved means as described in Sec. 112.2, 
the availability of the quantity of boom identified in the plan for this 
purpose.
    9.6 The plan must indicate the availability of temporary storage 
capacity to meet section 12.2 of this appendix. If available storage 
capacity is insufficient to meet this level, then the effective daily 
recovery capacity must be derated (downgraded) to the limits of the 
available storage capacity.
    9.7 The following is an example of a medium discharge volume 
planning calculation for equipment identification in a higher volume 
port area:
    The facility's largest aboveground storage tank volume is 840,000 
gallons. Ten percent of this capacity is 84,000 gallons. Because 10 
percent of the facility's largest tank, or 84,000 gallons, is greater 
than 36,000 gallons, 36,000 gallons is used as the planning volume. The 
effective daily recovery capacity is 50 percent of the planning volume, 
or 18,000 gallons per day. The ability of oil recovery devices to meet 
this capacity must be calculated using the procedures in section 6 of 
this appendix. Temporary storage capacity available on-scene must equal 
twice the daily recovery capacity as indicated in section 12.2 of this 
appendix, or 36,000 gallons per day. This is the information the 
facility owner or operator must use to identify and ensure the 
availability of the required response resources, by contract or other 
approved means as described in Sec. 112.2. The facility owner shall 
also identify how much boom is available for use.

[[Page 82]]

  10.0 Calculating Planning Volumes for a Worst Case Discharge--Animal 
                        Fats and Vegetable Oils.

    10.1 A facility owner or operator shall plan for a response to the 
facility's worst case discharge. The planning for on-water oil recovery 
must take into account a loss of some oil to the environment due to 
physical, chemical, and biological processes, potential increases in 
volume due to emulsification, and the potential for deposition of oil on 
the shoreline or on sediments. The response planning procedures for 
animal fats and vegetable oils are discussed in section 10.7 of this 
appendix. You may use alternate response planning procedures for animal 
fats and vegetable oils if those procedures result in environmental 
protection equivalent to that provided by the procedures in section 10.7 
of this appendix.
    10.2 The following procedures must be used by a facility owner or 
operator in determining the required on-water oil recovery capacity:
    10.2.1 The following must be determined: the worst case discharge 
volume of oil in the facility; the appropriate group(s) for the types of 
oil handled, stored, or transported at the facility (Groups A, B, C); 
and the facility's specific operating area. See sections 1.2.1 and 1.2.9 
of this appendix for the definitions of animal fats and vegetable oils 
and groups thereof. Facilities that handle, store, or transport oil from 
different oil groups must calculate each group separately, unless the 
oil group constitutes 10 percent or less by volume of the facility's 
total oil storage capacity. This information is to be used with Table 6 
of this appendix to determine the percentages of the total volume to be 
used for removal capacity planning. Table 6 of this appendix divides the 
volume into three categories: oil lost to the environment; oil deposited 
on the shoreline; and oil available for on-water recovery.
    10.2.2 The on-water oil recovery volume shall, as appropriate, be 
adjusted using the appropriate emulsification factor found in Table 7 of 
this appendix. Facilities that handle, store, or transport oil from 
different groups must compare the on-water recovery volume for each oil 
group (unless the oil group constitutes 10 percent or less by volume of 
the facility's total storage capacity) and use the calculation that 
results in the largest on-water oil recovery volume to plan for the 
amount of response resources for a worst case discharge.
    10.2.3 The adjusted volume is multiplied by the on-water oil 
recovery resource mobilization factor found in Table 4 of this appendix 
from the appropriate operating area and response tier to determine the 
total on-water oil recovery capacity in barrels per day that must be 
identified or contracted to arrive on-scene within the applicable time 
for each response tier. Three tiers are specified. For higher volume 
port areas, the contracted tiers of resources must be located such that 
they are capable of arriving on-scene within 6 hours for Tier 1, 30 
hours for Tier 2, and 54 hours for Tier 3 of the discovery of a 
discharge. For all other rivers and canals, inland, nearshore areas, and 
the Great Lakes, these tiers are 12, 36, and 60 hours.
    10.2.4 The resulting on-water oil recovery capacity in barrels per 
day for each tier is used to identify response resources necessary to 
sustain operations in the applicable operating area. The equipment shall 
be capable of sustaining operations for the time period specified in 
Table 6 of this appendix. The facility owner or operator shall identify 
and ensure, by contract or other approved means as described in Sec. 
112.2, the availability of sufficient oil spill recovery devices to 
provide the effective daily oil recovery capacity required. If the 
required capacity exceeds the applicable cap specified in Table 5 of 
this appendix, then a facility owner or operator shall ensure, by 
contract or other approved means as described in Sec. 112.2, only for 
the quantity of resources required to meet the cap, but shall identify 
sources of additional resources as indicated in section 5.4 of this 
appendix. The owner or operator of a facility whose planning volume 
exceeded the cap in 1998 must make arrangements to identify and ensure, 
by contract or other approved means as described in Sec. 112.2, the 
availability of additional capacity to be under contract by 2003, as 
appropriate. For a facility that handles multiple groups of oil, the 
required effective daily recovery capacity for each oil group is 
calculated before applying the cap. The oil group calculation resulting 
in the largest on-water recovery volume must be used to plan for the 
amount of response resources for a worst case discharge, unless the oil 
group comprises 10 percent or less by volume of the facility's oil 
storage capacity.
    10.3 The procedures discussed in sections 10.3.1 through 10.3.3 of 
this appendix must be used to calculate the planning volume for 
identifying shoreline cleanup capacity (for Groups A and B oils).
    10.3.1 The following must be determined: the worst case discharge 
volume of oil for the facility; the appropriate group(s) for the types 
of oil handled, stored, or transported at the facility (Groups A or B); 
and the geographic area(s) in which the facility operates (i.e., 
operating areas). For a facility handling, storing, or transporting oil 
from different groups, each group must be calculated separately. Using 
this information, Table 6 of this appendix must be used to determine the 
percentages of the total volume to be used for shoreline cleanup 
resource planning.
    10.3.2 The shoreline cleanup planning volume must be adjusted to 
reflect an emulsification factor using the same procedure as described 
in section 10.2.2 of this appendix.

[[Page 83]]

    10.3.3 The resulting volume shall be used to identify an oil spill 
removal organization with the appropriate shoreline cleanup capability.
    10.4 A response plan must identify response resources with fire 
fighting capability appropriate for the risk of fire and explosion at 
the facility from the discharge or threat of discharge of oil. The owner 
or operator of a facility that handles, stores, or transports Group A or 
B oils that does not have adequate fire fighting resources located at 
the facility or that cannot rely on sufficient local fire fighting 
resources must identify adequate fire fighting resources. The facility 
owner or operator shall ensure, by contract or other approved means as 
described in Sec. 112.2, the availability of these resources. The 
response plan must also identify an individual to work with the fire 
department for Group A or B oil fires. This individual shall also verify 
that sufficient well-trained fire fighting resources are available 
within a reasonable response time to a worst case scenario. The 
individual may be the qualified individual identified in the response 
plan or another appropriate individual located at the facility.
    10.5 The following is an example of the procedure described in 
sections 10.2 and 10.3 of this appendix. A facility with a 37.04 million 
gallon (881,904 barrel) capacity of several types of vegetable oils is 
located in the Inland Operating Area. The vegetable oil with the highest 
specific gravity stored at the facility is soybean oil (specific gravity 
0.922, Group B vegetable oil). The facility has ten aboveground oil 
storage tanks with a combined total capacity of 18 million gallons 
(428,571 barrels) and without secondary containment. The remaining 
facility tanks are inside secondary containment structures. The largest 
aboveground oil storage tank (3 million gallons or 71,428 barrels) has 
its own secondary containment. Two 2.1 million gallon (50,000 barrel) 
tanks (that are not connected by a manifold) are within a common 
secondary containment tank area, which is capable of holding 4.2 million 
gallons (100,000 barrels) plus sufficient freeboard.
    10.5.1 The worst case discharge for the facility is calculated by 
adding the capacity of all aboveground vegetable oil storage tanks 
without secondary containment (18.0 million gallons) plus the capacity 
of the largest aboveground storage tank inside secondary containment 
(3.0 million gallons). The resulting worst case discharge is 21 million 
gallons or 500,000 barrels.
    10.5.2 With a specific worst case discharge identified, the planning 
volume for on-water recovery can be identified as follows:

Worst case discharge: 21 million gallons (500,000 barrels) of Group B 
vegetable oil
Operating Area: Inland
Planned percent recovered floating vegetable oil (from Table 6, column 
Nearshore/Inland/Great Lakes): Inland, Group B is 20%
Emulsion factor (from Table 7): 2.0
Planning volumes for on-water recovery: 21,000,000 gallons x 0.2 x 2.0 = 
8,400,000 gallons or 200,000 barrels.
Determine required resources for on-water recovery for each of the three 
tiers using mobilization factors (from Table 4, column Inland/Nearshore/
Great Lakes)

 planning volume..........................
Estimated Daily Recovery Capacity (bbls)..    30,000    50,000    80,000
------------------------------------------------------------------------

    10.5.3 Because the requirements for On-Water Recovery Resources for 
Tiers 1, 2, and 3 for Inland Operating Area exceed the caps identified 
in Table 5 of this appendix, the facility owner will contract for a 
response of 12,500 barrels per day (bpd) for Tier 1, 25,000 bpd for Tier 
2, and 50,000 bpd for Tier 3. Resources for the remaining 17,500 bpd for 
Tier 1, 25,000 bpd for Tier 2, and 30,000 bpd for Tier 3 shall be 
identified but need not be contracted for in advance.
    10.5.4 With the specific worst case discharge identified, the 
planning volume of onshore recovery can be identified as follows:

Worst case discharge: 21 million gallons (500,000 barrels) of Group B 
vegetable oil
Operating Area: Inland
Planned percent recovered floating vegetable oil from onshore (from 
Table 6, column Nearshore/Inland/Great Lakes): Inland, Group B is 65%
Emulsion factor (from Table 7): 2.0
Planning volumes for shoreline recovery:
21,000,000 gallons x 0.65 x 2.0 = 27,300,000 gallons or 650,000 barrels

    10.5.5 The facility owner or operator shall, as appropriate, also 
identify or contract for quantities of boom identified in the response 
plan for the protection of fish and wildlife and sensitive environments 
within the area potentially impacted by a worst case discharge from the 
facility. For further description of fish and wildlife and sensitive 
environments, see Appendices I, II, and III to DOC/NOAA's ``Guidance for 
Facility and Vessel Response Plans: Fish and Wildlife and Sensitive 
Environments,'' (see Appendix E to this part, section 13, for 
availability) and the applicable ACP. Attachment C-III to Appendix C 
provides a method for calculating a planning distance to fish and 
wildlife and sensitive environments and public drinking

water intakes that may be adversely affected in the event of a worst 
case discharge.
    10.6 The procedures discussed in sections 10.6.1 through 10.6.3 of 
this appendix must be used to determine appropriate response resources 
for facilities with Group C oils.
    10.6.1 The owner or operator of a facility that handles, stores, or 
transports Group C oils shall, as appropriate, identify the response 
resources available by contract or other approved means, as described in 
Sec. 112.2. The equipment identified in a response plan shall, as 
appropriate, include:
    (1) Sonar, sampling equipment, or other methods for locating the oil 
on the bottom or suspended in the water column;
    (2) Containment boom, sorbent boom, silt curtains, or other methods 
for containing the oil that may remain floating on the surface or to 
reduce spreading on the bottom;
    (3) Dredges, pumps, or other equipment necessary to recover oil from 
the bottom and shoreline;
    (4) Equipment necessary to assess the impact of such discharges; and
    (5) Other appropriate equipment necessary to respond to a discharge 
involving the type of oil handled, stored, or transported.
    10.6.2 Response resources identified in a response plan for a 
facility that handles, stores, or transports Group C oils under section 
10.6.1 of this appendix shall be capable of being deployed on scene 
within 24 hours of discovery of a discharge.
    10.6.3 A response plan must identify response resources with fire 
fighting capability. The owner or operator of a facility that handles, 
stores, or transports Group C oils that does not have adequate fire 
fighting resources located at the facility or that cannot rely on 
sufficient local fire fighting resources must identify adequate fire 
fighting resources. The owner or operator shall ensure, by contract or 
other approved means as described in Sec. 112.2, the availability of 
these resources. The response plan shall also identify an individual 
located at the facility to work with the fire department for Group C oil 
fires. This individual shall also verify that sufficient well-trained 
fire fighting resources are available within a reasonable response time 
to respond to a worst case discharge. The individual may be the 
qualified individual identified in the response plan or another 
appropriate individual located at the facility.
    10.7 The procedures described in sections 10.7.1 through 10.7.5 of 
this appendix must be used to determine appropriate response plan 
development and evaluation criteria for facilities that handle, store, 
or transport animal fats and vegetable oils. Refer to section 11 of this 
appendix for information on the limitations on the use of chemical 
agents for inland and nearshore areas.
    10.7.1 An owner or operator of a facility that handles, stores, or 
transports animal fats and vegetable oils must provide information in 
the response plan that identifies:
    (1) Procedures and strategies for responding to a worst case 
discharge of animal fats and vegetable oils to the maximum extent 
practicable; and
    (2) Sources of the equipment and supplies necessary to locate, 
recover, and mitigate such a discharge.
    10.7.2 An owner or operator of a facility that handles, stores, or 
transports animal fats and vegetable oils must ensure that any equipment 
identified in a response plan is capable of operating in the geographic 
area(s) (i.e., operating environments) in which the facility operates 
using the criteria in Table 1 of this appendix. When evaluating the 
operability of equipment, the facility owner or operator must consider 
limitations that are identified in the appropriate ACPs, including:
    (1) Ice conditions;
    (2) Debris;
    (3) Temperature ranges; and
    (4) Weather-related visibility.
    10.7.3. The owner or operator of a facility that handles, stores, or 
transports animal fats and vegetable oils must identify the response 
resources that are available by contract or other approved means, as 
described in Sec. 112.2. The equipment described in the response plan 
shall, as appropriate, include:
    (1) Containment boom, sorbent boom, or other methods for containing 
oil floating on the surface or to protect shorelines from impact;
    (2) Oil recovery devices appropriate for the type of animal fat or 
vegetable oil carried; and
    (3) Other appropriate equipment necessary to respond to a discharge 
involving the type of oil carried.
    10.7.4 Response resources identified in a response plan according to 
section 10.7.3 of this appendix must be capable of commencing an 
effective on-scene response within the applicable tier response times in 
section 5.3 of this appendix.
    10.7.5 A response plan must identify response resources with fire 
fighting capability. The owner or operator of a facility that handles, 
stores, or transports animal fats and vegetable oils that does not have 
adequate fire fighting resources located at the facility or that cannot 
rely on sufficient local fire fighting resources must identify adequate 
fire fighting resources. The owner or operator shall ensure, by contract 
or other approved means as described in Sec. 112.2, the availability of 
these resources. The response plan shall also identify an individual 
located at the facility to work with the fire department for animal fat 
and vegetable oil fires. This individual shall also verify that 
sufficient well-trained fire fighting resources are available within a 
reasonable response time to respond to a worst case discharge.

[[Page 85]]

The individual may be the qualified individual identified in the 
response plan or another appropriate individual located at the facility.

    11.0 Determining the Availability of Alternative Response Methods

    11.1 For chemical agents to be identified in a response plan, they 
must be on the NCP Product Schedule that is maintained by EPA. (Some 
States have a list of approved dispersants for use within State waters. 
Not all of these State-approved dispersants are listed on the NCP 
Product Schedule.)
    11.2 Identification of chemical agents in the plan does not imply 
that their use will be authorized. Actual authorization will be governed 
by the provisions of the NCP and the applicable ACP.

   12.0 Additional Equipment Necessary to Sustain Response Operations

    12.1 A facility owner or operator shall identify sufficient response 
resources available, by contract or other approved means as described in 
Sec. 112.2, to respond to a medium discharge of animal fats or 
vegetables oils for that facility. This will require response resources 
capable of containing and collecting up to 36,000 gallons of oil or 10 
percent of the worst case discharge, whichever is less. All equipment 
identified must be designed to operate in the applicable operating 
environment specified in Table 1 of this appendix.
    12.2 A facility owner or operator shall evaluate the availability of 
adequate temporary storage capacity to sustain the effective daily 
recovery capacities from equipment identified in the plan. Because of 
the inefficiencies of oil spill recovery devices, response plans must 
identify daily storage capacity equivalent to twice the effective daily 
recovery capacity required on-scene. This temporary storage capacity may 
be reduced if a facility owner or operator can demonstrate by waste 
stream analysis that the efficiencies of the oil recovery devices, 
ability to decant waste, or the availability of alternative temporary 
storage or disposal locations will reduce the overall volume of oily 
material storage.
    12.3 A facility owner or operator shall ensure that response 
planning includes the capability to arrange for disposal of recovered 
oil products. Specific disposal procedures will be addressed in the 
applicable ACP.

                1.0 Model Facility-Specific Response Plan

    (A) Owners or operators of facilities regulated under this part 
which pose a threat of substantial harm to the environment by 
discharging oil into or on navigable waters or adjoining shorelines are 
required to prepare and submit facility-specific response plans to EPA 
in accordance with the provisions in this appendix. This appendix 
further describes the required elements in Sec. 112.20(h).
    (B) Response plans must be sent to the appropriate EPA Regional 
office. Figure F-1 of this Appendix lists each EPA Regional office and 
the address where owners or operators must submit their response plans. 
Those facilities deemed by the Regional Administrator (RA) to pose a 
threat of significant and substantial harm to the environment will have 
their plans reviewed and approved by EPA. In certain cases, information 
required in the model response plan is similar to information currently 
maintained in the facility's Spill Prevention, Control, and 
Countermeasures (SPCC) Plan as required by 40 CFR 112.3. In these cases, 
owners or operators may reproduce the information and include a 
photocopy in the response plan.
    (C) A complex may develop a single response plan with a set of core 
elements for all regulating agencies and separate sections for the non-
transportation-related and transportation-related components, as 
described in Sec. 112.20(h). Owners or operators of large facilities 
that handle, store, or transport oil at more than one geographically 
distinct location (e.g., oil storage areas at opposite ends of a single, 
continuous parcel of property) shall, as appropriate, develop separate 
sections of the response plan for each storage area.

                   1.1 Emergency Response Action Plan

    Several sections of the response plan shall be co-located for easy 
access by response personnel during an actual emergency or oil 
discharge. This collection of sections shall be called the Emergency 
Response Action Plan. The Agency intends that the Action Plan contain 
only as much information as is necessary to combat the discharge and be 
arranged so response actions are not delayed. The Action Plan may be 
arranged in a number of ways. For example, the sections of the Emergency 
Response Action Plan may be photocopies or condensed versions of the

[[Page 98]]

forms included in the associated sections of the response plan. Each 
Emergency Response Action Plan section may be tabbed for quick 
reference. The Action Plan shall be maintained in the front of the same 
binder that contains the complete response plan or it shall be contained 
in a separate binder. In the latter case, both binders shall be kept 
together so that the entire plan can be accessed by the qualified 
individual and appropriate spill response personnel. The Emergency 
Response Action Plan shall be made up of the following sections:

1. Qualified Individual Information (Section 1.2) partial
2. Emergency Notification Phone List (Section 1.3.1) partial
3. Spill Response Notification Form (Section 1.3.1) partial
4. Response Equipment List and Location (Section 1.3.2) complete
5. Response Equipment Testing and Deployment (Section 1.3.3) complete
6. Facility Response Team (Section 1.3.4) partial
7. Evacuation Plan (Section 1.3.5) condensed
8. Immediate Actions (Section 1.7.1) complete
9. Facility Diagram (Section 1.9) complete

                        1.2 Facility Information

    The facility information form is designed to provide an overview of 
the site and a description of past activities at the facility. Much of 
the information required by this section may be obtained from the 
facility's existing SPCC Plan.
    1.2.1 Facility name and location: Enter facility name and street 
address. Enter the address of corporate headquarters only if corporate 
headquarters are physically located at the facility. Include city, 
county, state, zip code, and phone number.
    1.2.2 Latitude and Longitude: Enter the latitude and longitude of 
the facility. Include degrees, minutes, and seconds of the main entrance 
of the facility.
    1.2.3 Wellhead Protection Area: Indicate if the facility is located 
in or drains into a wellhead protection area as defined by the Safe 
Drinking Water Act of 1986 (SDWA). \1\ The response plan requirements in 
the Wellhead Protection Program are outlined by the State or Territory 
in which the facility resides.
---------------------------------------------------------------------------

    \1\ A wellhead protection area is defined as the surface and 
subsurface area surrounding a water well or wellfield, supplying a 
public water system, through which contaminants are reasonably likely to 
move toward and reach such water well or wellfield. For further 
information regarding State and territory protection programs, facility 
owners or operators may contact the SDWA Hotline at 1-800-426-4791.
---------------------------------------------------------------------------

    1.2.4 Owner/operator: Write the name of the company or person 
operating the facility and the name of the person or company that owns 
the facility, if the two are different. List the address of the owner, 
if the two are different.
    1.2.5 Qualified Individual: Write the name of the qualified 
individual for the entire facility. If more than one person is listed, 
each individual indicated in this section shall have full authority to 
implement the facility response plan. For each individual, list: name, 
position, home and work addresses (street addresses, not P.O. boxes), 
emergency phone number, and specific response training experience.
    1.2.6 Date of Oil Storage Start-up: Enter the year which the present 
facility first started storing oil.
    1.2.7 Current Operation: Briefly describe the facility's operations 
and include the North American Industrial Classification System (NAICS) 
code.
    1.2.8 Dates and Type of Substantial Expansion: Include information 
on expansions that have occurred at the facility. Examples of such 
expansions include, but are not limited to: Throughput expansion, 
addition of a product line, change of a product line, and installation 
of additional oil storage capacity. The data provided shall include all 
facility historical information and detail the expansion of the 
facility. An example of substantial expansion is any material alteration 
of the facility which causes the owner or operator of the facility to 
re-evaluate and increase the response equipment necessary to adequately 
respond to a worst case discharge from the facility.

                   1.3 Emergency Response Information

    (A) The information provided in this section shall describe what 
will be needed in an actual emergency involving the discharge of oil or 
a combination of hazardous substances and oil discharge. The Emergency 
Response Information section of the plan must include the following 
components:
    (1) The information provided in the Emergency Notification Phone 
List in section 1.3.1 identifies and prioritizes the names and phone 
numbers of the organizations and personnel that need to be notified 
immediately in the event of an emergency. This section shall include all 
the appropriate phone numbers for the facility. These numbers must be 
verified each time the plan is updated. The contact list must be 
accessible to all facility employees to ensure that, in case of a 
discharge, any employee on site could immediately notify the appropriate 
parties.
    (2) The Spill Response Notification Form in section 1.3.1 creates a 
checklist of information that shall be provided to the National Response 
Center (NRC) and other response personnel. All information on this 
checklist must be known at the time of notification, or be in the 
process of being collected. This notification form is based on a similar 
form used by the NRC. Note: Do not delay spill notification to collect 
the information on the list.
    (3) Section 1.3.2 provides a description of the facility's list of 
emergency response equipment and location of the response equipment. 
When appropriate, the amount of oil that emergency response equipment 
can handle and any limitations (e.g., launching sites) must be 
described.
    (4) Section 1.3.3 provides information regarding response equipment 
tests and deployment drills. Response equipment deployment exercises 
shall be conducted to ensure that response equipment is operational and 
the personnel who would operate the equipment in a spill response are 
capable of deploying and operating it. Only a representative sample of 
each type of response equipment needs to be deployed and operated, as 
long as the remainder is properly maintained. If appropriate, testing of 
response equipment may be conducted while it is being deployed. 
Facilities without facility-owned response equipment must ensure that 
the oil spill removal organization that is identified in the response 
plan to provide this response equipment certifies that the deployment 
exercises have been met. Refer to the National Preparedness for Response 
Exercise Program (PREP) Guidelines (see appendix E to this part, section 
13, for availability), which satisfy Oil Pollution Act (OPA) response 
exercise requirements.
    (5) Section 1.3.4 lists the facility response personnel, including 
those employed by the facility and those under contract to the facility 
for response activities, the amount of time needed for personnel to 
respond, their responsibility in the case of an emergency, and their 
level of response training. Three different forms are included in this 
section. The Emergency Response Personnel List shall be composed of all 
personnel employed by the facility whose duties involve responding to 
emergencies, including oil discharges, even when they are not physically 
present at the site. An example of this type of person would be the 
Building Engineer-in-Charge or Plant Fire Chief. The second form is a 
list of the Emergency Response Contractors (both primary and secondary) 
retained by the facility. Any changes in contractor status must be 
reflected in updates to the response plan. Evidence of contracts with 
response contractors shall be included in this section so that the 
availability of resources can be verified. The last form is the Facility 
Response Team List, which shall be composed of both emergency response 
personnel (referenced by job title/position) and emergency response 
contractors, included in one of the two lists described above, that will 
respond immediately upon discovery of an oil discharge or other 
emergency (i.e., the first people to respond). These are to be persons 
normally on the facility premises or primary response contractors. 
Examples of these personnel would be the Facility Hazardous Materials 
(HAZMAT) Spill Team 1, Facility Fire Engine Company 1, Production 
Supervisor, or Transfer Supervisor. Company personnel must be able to 
respond immediately and adequately if contractor support is not 
available.
    (6) Section 1.3.5 lists factors that must, as appropriate, be 
considered when preparing an evacuation plan.
    (7) Section 1.3.6 references the responsibilities of the qualified 
individual for the facility in the event of an emergency.
    (B) The information provided in the emergency response section will 
aid in the assessment of the facility's ability to respond to a worst 
case discharge and will identify additional assistance that may be 
needed. In addition, the facility owner or operator may want to produce 
a wallet-size card containing a checklist of the immediate response and 
notification steps to be taken in the event of an oil discharge.

                         1.3.5 Evacuation Plans

    1.3.5.1 Based on the analysis of the facility, as discussed 
elsewhere in the plan, a facility-wide evacuation plan shall be 
developed. In addition, plans to evacuate parts of the facility that are 
at a high risk of exposure in the event of a discharge or other release 
must be developed. Evacuation routes must be shown on a diagram of the 
facility (see section 1.9 of this appendix). When developing evacuation 
plans, consideration must be given to the following factors, as 
appropriate:
    (1) Location of stored materials;
    (2) Hazard imposed by discharged material;
    (3) Discharge flow direction;
    (4) Prevailing wind direction and speed;
    (5) Water currents, tides, or wave conditions (if applicable);
    (6) Arrival route of emergency response personnel and response 
equipment;
    (7) Evacuation routes;
    (8) Alternative routes of evacuation;
    (9) Transportation of injured personnel to nearest emergency medical 
facility;
    (10) Location of alarm/notification systems;
    (11) The need for a centralized check-in area for evacuation 
validation (roll call);
    (12) Selection of a mitigation command center; and
    (13) Location of shelter at the facility as an alternative to 
evacuation.
    1.3.5.2 One resource that may be helpful to owners or operators in 
preparing this section of the response plan is The Handbook of Chemical 
Hazard Analysis Procedures by the Federal Emergency Management Agency 
(FEMA), Department of Transportation (DOT), and EPA. The Handbook of 
Chemical Hazard Analysis Procedures is available from: FEMA , 
Publication Office, 500 C. Street, S.W., Washington, DC 20472, (202) 
646-3484.
    1.3.5.3 As specified in Sec. 112.20(h)(1)(vi), the facility owner 
or operator must reference existing community evacuation plans, as 
appropriate.

                   1.3.6 Qualified Individual's Duties

    The duties of the designated qualified individual are specified in 
Sec. 112.20(h)(3)(ix). The qualified individual's duties must be 
described and be consistent with the minimum requirements in Sec. 
112.20(h)(3)(ix). In addition, the qualified individual must be 
identified with the Facility Information in section 1.2 of the response 
plan.

                          1.4 Hazard Evaluation

    This section requires the facility owner or operator to examine the 
facility's operations closely and to predict where discharges could 
occur. Hazard evaluation is a widely used industry practice that allows 
facility owners or operators to develop a complete understanding of 
potential hazards and the response actions necessary to address these 
hazards. The Handbook of Chemical Hazard Analysis Procedures, prepared 
by the EPA, DOT, and the FEMA and the Hazardous Materials Emergency 
Planning Guide (NRT-1), prepared by the National Response Team are good 
references for conducting a hazard analysis. Hazard identification and 
evaluation will assist facility owners or operators in planning for 
potential discharges, thereby reducing the severity of discharge impacts 
that may occur in the future. The evaluation also may help the operator 
identify and correct potential sources of discharges. In addition, 
special hazards to workers and emergency response personnel's health and 
safety shall be evaluated, as well as the facility's oil spill history.

                       1.4.1 Hazard Identification

    The Tank and Surface Impoundment (SI) forms, or their equivalent, 
that are part of this section must be completed according to the 
directions below. (``Surface Impoundment'' means a facility or part of a 
facility which is a natural topographic depression, man-made excavation, 
or diked area formed primarily of earthen materials (although it may be 
lined with man-made materials), which is designed to hold an 
accumulation of liquid wastes or wastes containing free liquids, and 
which is not an injection well or a seepage facility.) Similar 
worksheets, or their equivalent, must be developed for any other type of 
storage containers.
    (1) List each tank at the facility with a separate and distinct 
identifier. Begin aboveground tank identifiers with an ``A'' and 
belowground tank identifiers with a ``B'', or submit multiple sheets 
with the aboveground tanks and belowground tanks on separate sheets.
    (2) Use gallons for the maximum capacity of a tank; and use square 
feet for the area.
    (3) Using the appropriate identifiers and the following 
instructions, fill in the appropriate forms:
    (a) Tank or SI number--Using the aforementioned identifiers (A or B) 
or multiple reporting sheets, identify each tank or SI at the facility 
that stores oil or hazardous materials.
    (b) Substance Stored--For each tank or SI identified, record the 
material that is stored therein. If the tank or SI is used to store more 
than one material, list all of the stored materials.
    (c) Quantity Stored--For each material stored in each tank or SI, 
report the average volume of material stored on any given day.
    (d) Tank Type or Surface Area/Year--For each tank, report the type 
of tank (e.g., floating top), and the year the tank was originally 
installed. If the tank has been refabricated, the year that the latest 
refabrication was completed must be recorded in parentheses next to the 
year installed. For

[[Page 105]]

each SI, record the surface area of the impoundment and the year it went 
into service.
    (e) Maximum Capacity--Record the operational maximum capacity for 
each tank and SI. If the maximum capacity varies with the season, record 
the upper and lower limits.
    (f) Failure/Cause--Record the cause and date of any tank or SI 
failure which has resulted in a loss of tank or SI contents.
    (4) Using the numbers from the tank and SI forms, label a schematic 
drawing of the facility. This drawing shall be identical to any 
schematic drawings included in the SPCC Plan.
    (5) Using knowledge of the facility and its operations, describe the 
following in writing:
    (a) The loading and unloading of transportation vehicles that risk 
the discharge of oil or release of hazardous substances during transport 
processes. These operations may include loading and unloading of trucks, 
railroad cars, or vessels. Estimate the volume of material involved in 
transfer operations, if the exact volume cannot be determined.
    (b) Day-to-day operations that may present a risk of discharging oil 
or releasing a hazardous substance. These activities include scheduled 
venting, piping repair or replacement, valve maintenance, transfer of 
tank contents from one tank to another, etc. (not including 
transportation-related activities). Estimate the volume of material 
involved in these operations, if the exact volume cannot be determined.
    (c) The secondary containment volume associated with each tank and/
or transfer point at the facility. The numbering scheme developed on the 
tables, or an equivalent system, must be used to identify each 
containment area. Capacities must be listed for each individual unit 
(tanks, slumps, drainage traps, and ponds), as well as the facility 
total.
    (d) Normal daily throughput for the facility and any effect on 
potential discharge volumes that a negative or positive change in that 
throughput may cause.

    The vulnerability analysis shall address the potential effects 
(i.e., to human health, property, or the environment) of an oil 
discharge. Attachment C-III to Appendix C to this part provides a method 
that owners or operators shall use to determine appropriate distances 
from the facility to fish and wildlife and sensitive environments. 
Owners or operators can use a comparable formula that is considered 
acceptable by the RA. If a comparable formula is used, documentation of 
the reliability and analytical soundness of the formula must be attached 
to the response plan cover sheet. This analysis must be prepared for 
each facility and, as appropriate, must discuss the vulnerability of:
    (1) Water intakes (drinking, cooling, or other);
    (2) Schools;
    (3) Medical facilities;
    (4) Residential areas;
    (5) Businesses;
    (6) Wetlands or other sensitive environments; \2\
---------------------------------------------------------------------------

    \2\ Refer to the DOC/NOAA ``Guidance for Facility and Vessel 
Response Plans: Fish and Wildlife and Sensitive Environments'' (See 
appendix E to this part, section 13, for availability).
---------------------------------------------------------------------------

    (7) Fish and wildlife;
    (8) Lakes and streams;
    (9) Endangered flora and fauna;
    (10) Recreational areas;
    (11) Transportation routes (air, land, and water);
    (12) Utilities; and
    (13) Other areas of economic importance (e.g., beaches, marinas) 
including terrestrially sensitive environments, aquatic environments, 
and unique habitats.

          1.4.3 Analysis of the Potential for an Oil Discharge

    Each owner or operator shall analyze the probability of a discharge 
occurring at the facility. This analysis shall incorporate factors such 
as oil discharge history, horizontal range of a potential discharge, and 
vulnerability to natural disaster, and shall, as appropriate, 
incorporate other factors such as tank age. This analysis will provide 
information for developing discharge scenarios for a worst case 
discharge and small and medium discharges and aid in the development of 
techniques to reduce the size and frequency of discharges. The owner or 
operator may need to research the age of the tanks the oil discharge 
history at the facility.

               1.4.4 Facility Reportable Oil Spill History

    Briefly describe the facility's reportable oil spill \3\ history for 
the entire life of the facility to the extent that such information is 
reasonably identifiable, including:
---------------------------------------------------------------------------

    \3\ As described in 40 CFR part 110, reportable oil spills are those 
that: (a) violate applicable water quality standards, or (b) cause a 
film or sheen upon or discoloration of the surface of the water or 
adjoining shorelines or cause a sludge or emulsion to be deposited 
beneath the surface of the water or upon adjoining shorelines.
---------------------------------------------------------------------------

    (1) Date of discharge(s);
    (2) List of discharge causes;
    (3) Material(s) discharged;
    (4) Amount discharged in gallons;
    (5) Amount of discharge that reached navigable waters, if 
applicable;
    (6) Effectiveness and capacity of secondary containment;
    (7) Clean-up actions taken;
    (8) Steps taken to reduce possibility of recurrence;
    (9) Total oil storage capacity of the tank(s) or impoundment(s) from 
which the material discharged;
    (10) Enforcement actions;
    (11) Effectiveness of monitoring equipment; and
    (12) Description(s) of how each oil discharge was detected.


[[Page 107]]


The information solicited in this section may be similar to requirements 
in 40 CFR 112.4(a). Any duplicate information required by Sec. 112.4(a) 
may be photocopied and inserted.

                         1.5 Discharge Scenarios

    In this section, the owner or operator is required to provide a 
description of the facility's worst case discharge, as well as a small 
and medium discharge, as appropriate. A multi-level planning approach 
has been chosen because the response actions to a discharge (i.e., 
necessary response equipment, products, and personnel) are dependent on 
the magnitude of the discharge. Planning for lesser discharges is 
necessary because the nature of the response may be qualitatively 
different depending on the quantity of the discharge. The facility owner 
or operator shall discuss the potential direction of the discharge 
pathway.

                    1.5.1 Small and Medium Discharges

    1.5.1.1 To address multi-level planning requirements, the owner or 
operator must consider types of facility-specific discharge scenarios 
that may contribute to a small or medium discharge. The scenarios shall 
account for all the operations that take place at the facility, 
including but not limited to:
    (1) Loading and unloading of surface transportation;
    (2) Facility maintenance;
    (3) Facility piping;
    (4) Pumping stations and sumps;
    (5) Oil storage tanks;
    (6) Vehicle refueling; and
    (7) Age and condition of facility and components.
    1.5.1.2 The scenarios shall also consider factors that affect the 
response efforts required by the facility. These include but are not 
limited to:
    (1) Size of the discharge;
    (2) Proximity to downgradient wells, waterways, and drinking water 
intakes;
    (3) Proximity to fish and wildlife and sensitive environments;
    (4) Likelihood that the discharge will travel offsite (i.e., 
topography, drainage);
    (5) Location of the material discharged (i.e., on a concrete pad or 
directly on the soil);
    (6) Material discharged;
    (7) Weather or aquatic conditions (i.e., river flow);
    (8) Available remediation equipment;
    (9) Probability of a chain reaction of failures; and
    (10) Direction of discharge pathway.

                       1.5.2 Worst Case Discharge

    1.5.2.1 In this section, the owner or operator must identify the 
worst case discharge volume at the facility. Worksheets for production 
and non-production facility owners or operators to use when calculating 
worst case discharge are presented in appendix D to this part. When 
planning for the worst case discharge response, all of the 
aforementioned factors listed in the small and medium discharge section 
of the response plan shall be addressed.
    1.5.2.2 For onshore storage facilities and production facilities, 
permanently manifolded oil storage tanks are defined as tanks that are 
designed, installed, and/or operated in such a manner that the multiple 
tanks function as one storage unit (i.e., multiple tank volumes are 
equalized). In this section of the response plan, owners or operators 
must provide evidence that oil storage tanks with common piping or 
piping systems are not operated as one unit. If such evidence is 
provided and is acceptable to the RA, the worst case discharge volume 
shall be based on the combined oil storage capacity of all manifold 
tanks or the oil storage capacity of the largest single oil storage tank 
within the secondary containment area, whichever is greater. For 
permanently manifolded oil storage tanks that function as one storage 
unit, the worst case discharge shall be based on the combined oil 
storage capacity of all manifolded tanks or the oil storage capacity of 
the largest single tank within a secondary containment area, whichever 
is greater. For purposes of the worst case discharge calculation, 
permanently manifolded oil storage tanks that are separated by internal 
divisions for each tank are considered to be single tanks and individual 
manifolded tank volumes are not combined.

                     1.6 Discharge Detection Systems

    In this section, the facility owner or operator shall provide a 
detailed description of the procedures and equipment used to detect 
discharges. A section on discharge detection by personnel and a 
discussion of automated discharge detection, if applicable, shall be 
included for both regular operations and after hours operations. In 
addition, the facility owner or operator shall discuss how the 
reliability of any automated system will be checked and how frequently 
the system will be inspected.

                 1.6.1 Discharge Detection by Personnel

    In this section, facility owners or operators shall describe the 
procedures and personnel that will detect any discharge of oil or 
release of a hazardous substance. A thorough discussion of facility 
inspections must be included. In addition, a description of initial 
response actions shall be addressed. This section shall reference 
section 1.3.1 of the response plan for emergency response information.

[[Page 108]]

                   1.6.2 Automated Discharge Detection

    In this section, facility owners or operators must describe any 
automated discharge detection equipment that the facility has in place. 
This section shall include a discussion of overfill alarms, secondary 
containment sensors, etc. A discussion of the plans to verify an 
automated alarm and the actions to be taken once verified must also be 
included.

                         1.7 Plan Implementation

    In this section, facility owners or operators must explain in detail 
how to implement the facility's emergency response plan by describing 
response actions to be carried out under the plan to ensure the safety 
of the facility and to mitigate or prevent discharges described in 
section 1.5 of the response plan. This section shall include the 
identification of response resources for small, medium, and worst case 
discharges; disposal plans; and containment and drainage planning. A 
list of those personnel who would be involved in the cleanup shall be 
identified. Procedures that the facility will use, where appropriate or 
necessary, to update their plan after an oil discharge event and the 
time frame to update the plan must be described.

 1.7.1 Response Resources for Small, Medium, and Worst Case Discharages

    1.7.1.1 Once the discharge scenarios have been identified in section 
1.5 of the response plan, the facility owner or operator shall identify 
and describe implementation of the response actions. The facility owner 
or operator shall demonstrate accessibility to the proper response 
personnel and equipment to effectively respond to all of the identified 
discharge scenarios. The determination and demonstration of adequate 
response capability are presented in appendix E to this part. In 
addition, steps to expedite the cleanup of oil discharges must be 
discussed. At a minimum, the following items must be addressed:
    (1) Emergency plans for spill response;
    (2) Additional response training;
    (3) Additional contracted help;
    (4) Access to additional response equipment/experts; and
    (5) Ability to implement the plan including response training and

                 1.7.3 Containment and Drainage Planning

    A proper plan to contain and control a discharge through drainage 
may limit the threat of harm to human health and the environment. This 
section shall describe how to contain and control a discharge through 
drainage, including:

[[Page 109]]

    (1) The available volume of containment (use the information 
presented in section 1.4.1 of the response plan);
    (2) The route of drainage from oil storage and transfer areas;
    (3) The construction materials used in drainage troughs;
    (4) The type and number of valves and separators used in the 
drainage system;
    (5) Sump pump capacities;
    (6) The containment capacity of weirs and booms that might be used 
and their location (see section 1.3.2 of this appendix); and
    (7) Other cleanup materials.
    In addition, a facility owner or operator must meet the inspection 
and monitoring requirements for drainage contained in 40 CFR part 112, 
subparts A through C. A copy of the containment and drainage plans that 
are required in 40 CFR part 112, subparts A through C may be inserted in 
this section, including any diagrams in those plans.
    Note: The general permit for stormwater drainage may contain 
additional requirements.

      1.8 Self-Inspection, Drills/Exercises, and Response Training

    The owner or operator must develop programs for facility response 
training and for drills/exercises according to the requirements of 40 
CFR 112.21. Logs must be kept for facility drills/exercises, personnel 
response training, and spill prevention meetings. Much of the 
recordkeeping information required by this section is also contained in 
the SPCC Plan required by 40 CFR 112.3. These logs may be included in 
the facility response plan or kept as an annex to the facility response 
plan.

                     1.8.1 Facility Self-Inspection

    Under 40 CFR 112.7(e), you must include the written procedures and 
records of inspections for each facility in the SPCC Plan. You must 
include the inspection records for each container, secondary 
containment, and item of response equipment at the facility. You must 
cross-reference the records of inspections of each container and 
secondary containment required by 40 CFR 112.7(e) in the facility 
response plan. The inspection record of response equipment is a new 
requirement in this plan. Facility self-inspection requires two-steps: 
(1) a checklist of things to inspect; and (2) a method of recording the 
actual inspection and its findings. You must note the date of each 
inspection. You must keep facility response plan records for five years. 
You must keep SPCC records for three years.

                        1.8.1.1. Tank Inspection

    The tank inspection checklist presented below has been included as 
guidance during inspections and monitoring. Similar requirements exist 
in 40 CFR part 112, subparts A through C. Duplicate information from the 
SPCC Plan may be photocopied and inserted in this section. The 
inspection checklist consists of the following items:

in 40 CFR part 112, subparts A through C. Similar requirements exist in 
40 CFR 112.7(e). Duplicate information from the SPCC Plan may be 
photocopied and inserted in this section.

                     1.8.2 Facility Drills/Exercises

    (A) CWA section 311(j)(5), as amended by OPA, requires the response 
plan to contain a description of facility drills/exercises. According to 
40 CFR 112.21(c), the facility owner or operator shall develop a program 
of facility response drills/exercises, including evaluation procedures. 
Following the PREP guidelines (see appendix E to this part, section 13, 
for availability) would satisfy a facility's requirements for drills/
exercises under this part. Alternately, under Sec. 112.21(c), a 
facility owner or operator may develop a program that is not based on 
the PREP guidelines. Such a program is subject to approval by the 
Regional Administrator based on the description of the program provided 
in the response plan.
    (B) The PREP Guidelines specify that the facility conduct internal 
and external drills/exercises. The internal exercises include: qualified 
individual notification drills, spill management team tabletop 
exercises, equipment deployment exercises, and unannounced exercises. 
External exercises include Area Exercises. Credit for an Area or 
Facility-specific Exercise will be given to the facility for an actual 
response to a discharge in the area if the plan was utilized for 
response to the discharge and the objectives of the Exercise were met 
and were properly evaluated, documented, and self-certified.
    (C) Section 112.20(h)(8)(ii) requires the facility owner or operator 
to provide a description of the drill/exercise program to be carried out 
under the response plan. Qualified Individual Notification Drill and 
Spill Management Team Tabletop Drill logs shall be provided in sections 
1.8.2.1 and 1.8.2.2, respectively. These logs may be included in the 
facility response plan or kept as an annex to the facility response 
plan. See section 1.3.3 of this appendix for Equipment Deployment Drill 
Logs.

                         1.8.3 Response Training

    Section 112.21(a) requires facility owners or operators to develop 
programs for facility response training. Facility owners or operators 
are required by Sec. 112.20(h)(8)(iii) to provide a description of the 
response training program to be carried out under the response plan. A 
facility's training program can be based on the USCG's Training Elements 
for Oil Spill Response, to the extent applicable to facility operations, 
or another response training program acceptable to the RA. The training 
elements are available from the USCG Office of Response (G-MOR) at (202) 
267-0518 or fax (202) 267-4085. Personnel response training logs and 
discharge prevention meeting logs shall be included in sections 1.8.3.1 
and 1.8.3.2 of the response plan respectively. These logs may be

                              1.9 Diagrams

    The facility-specific response plan shall include the following 
diagrams. Additional diagrams that would aid in the development of 
response plan sections may also be included.

(1) The Site Plan Diagram shall, as appropriate, include and identify:
    (A) the entire facility to scale;
    (B) above and below ground bulk oil storage tanks;
    (C) the contents and capacities of bulk oil storage tanks;
    (D) the contents and capacity of drum oil storage areas;
    (E) the contents and capacities of surface impoundments;
    (F) process buildings;
    (G) transfer areas;
    (H) secondary containment systems (location and capacity);

between the portion of the facility regulated by EPA and the portion(s) 
regulated by other Agencies. In most cases, this interface is defined as 
the last valve inside secondary containment before piping leaves the 
secondary containment area to connect to the transportation-related 
portion of the facility (i.e., the structure used or intended to be used 
to transfer oil to or from a vessel or pipeline). In the absence of 
secondary containment, this interface is the valve manifold adjacent to 
the tank nearest the transfer structure as described above. The 
interface may be defined differently at a specific facility if agreed to 
by the RA and the appropriate Federal official.

    (A) major sanitary and storm sewers, manholes, and drains;
    (B) weirs and shut-off valves;
    (C) surface water receiving streams;
    (D) fire fighting water sources;
    (E) other utilities;
    (F) response personnel ingress and egress;
    (G) response equipment transportation routes; and
    (H) direction of discharge flow from discharge points.
(3) The Site Evacuation Plan Diagram shall, as appropriate, include:
    (A) site plan diagram with evacuation route(s); and
    (B) location of evacuation regrouping areas.

                              1.10 Security

    According to 40 CFR 112.7(g) facilities are required to maintain a 
certain level of security, as appropriate. In this section, a 
description of the facility security shall be provided and include, as 
appropriate:

waters located within 4,000 feet of the high tide line or ordinary high 
water mark of a water identified in paragraphs (1)(i) through (v) of 
this definition where they are determined on a case-specific basis to 
have a significant nexus to a water identified in paragraphs (1)(i) 
through (iii) of this definition. For waters determined to have a 
significant nexus, the entire water is a water of the United States if a 
portion is located within the 100-year floodplain of a water identified 
in paragraphs (1)(i) through (iii) of this definition or within 4,000 
feet of the high tide line or ordinary high water mark. Waters 
identified in this paragraph shall not be combined with waters 
identified in paragraph (1)(vi) of this definition when performing a 
significant nexus analysis. If waters identified in this paragraph are 
also an adjacent water under paragraph (1)(vi), they are an adjacent 
water and no case-specific significant nexus analysis is required.
    (2) The following are not ``waters of the United States'' even where 
they otherwise meet the terms of paragraphs (1)(iv) through (viii) of 
this definition.
    (i) Prior converted cropland. Notwithstanding the determination of 
an area's status as prior converted cropland by any other Federal 
agency, for the purposes of the Clean Water Act, the final authority 
regarding Clean Water Act jurisdiction remains with EPA.
    (ii) The following ditches:
    (A) Ditches with ephemeral flow that are not a relocated tributary 
or excavated in a tributary.
    (B) Ditches with intermittent flow that are not a relocated 
tributary, excavated in a tributary, or drain wetlands.
    (C) Ditches that do not flow, either directly or through another 
water, into a water identified in paragraphs (1)(i) through (iii) of 
this definition.
    (iii) The following features:
    (A) Artificially irrigated areas that would revert to dry land 
should application of water to that area cease;
    (B) Artificial, constructed lakes and ponds created in dry land such 
as farm and stock watering ponds, irrigation ponds, settling basins, 
fields flooded for rice growing, log cleaning ponds, or cooling ponds;
    (C) Artificial reflecting pools or swimming pools created in dry 
land;
    (D) Small ornamental waters created in dry land;
    (E) Water-filled depressions created in dry land incidental to 
mining or construction activity, including pits excavated for obtaining 
fill, sand, or gravel that fill with water;

[[Page 142]]

    (F) Erosional features, including gullies, rills, and other 
ephemeral features that do not meet the definition of tributary, non-
wetland swales, and lawfully constructed grassed waterways; and
    (G) Puddles.
    (iv) Groundwater, including groundwater drained through subsurface 
drainage systems.
    (v) Stormwater control features constructed to convey, treat, or 
store stormwater that are created in dry land.
    (vi) Wastewater recycling structures constructed in dry land; 
detention and retention basins built for wastewater recycling; 
groundwater recharge basins; percolation ponds built for wastewater 
recycling; and water distributary structures built for wastewater 
recycling.
    (3) In this definition, the following terms apply:
    (i) Adjacent. The term adjacent means bordering, contiguous, or 
neighboring a water identified in paragraphs (1)(i) through (v) of this 
definition, including waters separated by constructed dikes or barriers, 
natural river berms, beach dunes, and the like. For purposes of 
adjacency, an open water such as a pond or lake includes any wetlands 
within or abutting its ordinary high water mark. Adjacency is not 
limited to waters located laterally to a water identified in paragraphs 
(1)(i) through (v) of this definition. Adjacent waters also include all 
waters that connect segments of a water identified in paragraphs (1)(i) 
through (v) or are located at the head of a water identified in 
paragraphs (1)(i) through (v) of this definition and are bordering, 
contiguous, or neighboring such water. Waters being used for established 
normal farming, ranching, and silviculture activities (33 U.S.C. 
1344(f)) are not adjacent.
    (ii) Neighboring. The term neighboring means:
    (A) All waters located within 100 feet of the ordinary high water 
mark of a water identified in paragraphs (1)(i) through (v) of this 
definition. The entire water is neighboring if a portion is located 
within 100 feet of the ordinary high water mark;
    (B) All waters located within the 100-year floodplain of a water 
identified in paragraphs (1)(i) through (v) of this definition and not 
more than 1,500 feet from the ordinary high water mark of such water. 
The entire water is neighboring if a portion is located within 1,500 
feet of the ordinary high water mark and within the 100-year floodplain;
    (C) All waters located within 1,500 feet of the high tide line of a 
water identified in paragraphs (1)(i) or (1)(iii) of this definition, 
and all waters within 1,500 feet of the ordinary high water mark of the 
Great Lakes. The entire water is neighboring if a portion is located 
within 1,500 feet of the high tide line or within 1,500 feet of the 
ordinary high water mark of the Great Lakes.
    (iii) Tributary and tributaries. The terms tributary and tributaries 
each mean a water that contributes flow, either directly or through 
another water (including an impoundment identified in paragraph (1)(iv) 
of this definition), to a water identified in paragraphs (1)(i) through 
(iii) of this definition that is characterized by the presence of the 
physical indicators of a bed and banks and an ordinary high water mark. 
These physical indicators demonstrate there is volume, frequency, and 
duration of flow sufficient to create a bed and banks and an ordinary 
high water mark, and thus to qualify as a tributary. A tributary can be 
a natural, man-altered, or man-made water and includes waters such as 
rivers, streams, canals, and ditches not excluded under paragraph (2) of 
this definition. A water that otherwise qualifies as a tributary under 
this definition does not lose its status as a tributary if, for any 
length, there are one or more constructed breaks (such as bridges, 
culverts, pipes, or dams), or one or more natural breaks (such as 
wetlands along the run of a stream, debris piles, boulder fields, or a 
stream that flows underground) so long as a bed and banks and an 
ordinary high water mark can be identified upstream of the break. A 
water that otherwise qualifies as a tributary under this definition does 
not lose its status as a tributary if it contributes flow through a 
water of the United States that does not meet the definition of 
tributary or through a non-jurisdictional water to a

[[Page 143]]

water identified in paragraphs (1)(i) through (iii) of this definition.
    (iv) Wetlands. The term wetlands means those areas that are 
inundated or saturated by surface or groundwater at a frequency and 
duration sufficient to support, and that under normal circumstances do 
support, a prevalence of vegetation typically adapted for life in 
saturated soil conditions. Wetlands generally include swamps, marshes, 
bogs, and similar areas.
    (v) Significant nexus. The term significant nexus means that a 
water, including wetlands, either alone or in combination with other 
similarly situated waters in the region, significantly affects the 
chemical, physical, or biological integrity of a water identified in 
paragraphs (1)(i) through (iii) of this definition. The term ``in the 
region'' means the watershed that drains to the nearest water identified 
in paragraphs (1)(i) through (iii) of this definition. For an effect to 
be significant, it must be more than speculative or insubstantial. 
Waters are similarly situated when they function alike and are 
sufficiently close to function together in affecting downstream waters. 
For purposes of determining whether or not a water has a significant 
nexus, the water's effect on downstream (1)(i) through (iii) waters 
shall be assessed by evaluating the aquatic functions identified in 
paragraphs (3)(v)(A) through (I) of this definition. A water has a 
significant nexus when any single function or combination of functions 
performed by the water, alone or together with similarly situated waters 
in the region, contributes significantly to the chemical, physical, or 
biological integrity of the nearest water identified in paragraphs 
(1)(i) through (iii) of this definition. Functions relevant to the 
significant nexus evaluation are the following:
    (A) Sediment trapping,
    (B) Nutrient recycling,
    (C) Pollutant trapping, transformation, filtering, and transport,
    (D) Retention and attenuation of flood waters,
    (E) Runoff storage,
    (F) Contribution of flow,
    (G) Export of organic matter,
    (H) Export of food resources, and
    (I) Provision of life cycle dependent aquatic habitat (such as 
foraging, feeding, nesting, breeding, spawning, or use as a nursery 
area) for species located in a water identified in paragraphs (1)(i) 
through (iii) of this section.
    (vi) Ordinary high water mark. The term ordinary high water mark 
means that line on the shore established by the fluctuations of water 
and indicated by physical characteristics such as a clear, natural line 
impressed on the bank, shelving, changes in the character of soil, 
destruction of terrestrial vegetation, the presence of litter and 
debris, or other appropriate means that consider the characteristics of 
the surrounding areas.
    (vii) High tide line. The term high tide line means the line of 
intersection of the land with the water's surface at the maximum height 
reached by a rising tide. The high tide line may be determined, in the 
absence of actual data, by a line of oil or scum along shore objects, a 
more or less continuous deposit of fine shell or debris on the foreshore 
or berm, other physical markings or characteristics, vegetation lines, 
tidal gages, or other suitable means that delineate the general height 
reached by a rising tide. The line encompasses spring high tides and 
other high tides that occur with periodic frequency but does not include 
storm surges in which there is a departure from the normal or predicted 
reach of the tide due to the piling up of water against a coast by 
strong winds such as those accompanying a hurricane or other intense 
storm.
    Offshore facility means any facility of any kind located in, on, or 
under, any of the navigable waters of the United States, and any 
facility of any kind which is subject to the jurisdiction of the United 
States and is located in, on, or under any other waters, other than a 
vessel or a public vessel;
    Onshore facility means any facility (including, but not limited to, 
motor vehicles and rolling stock) of any kind located in, on, or under, 
any land within the United States other than submerged land;
    Otherwise subject to the jurisdiction of the United States means 
subject to the jurisdiction of the United States by virtue of United 
States citizenship,

United States vessel documentation or numbering, or as provided for by 
international agreement to which the United States is a party.
    A discharge in connection with activities under the Outer 
Continental Shelf Lands Act or the Deepwater Port Act of 1974, or which 
may affect natural resources belonging to, appertaining to, or under the 
exclusive management authority of the United States (including resources 
under the Fishery Conservation and Management Act of 1976), means: (1) A 
discharge into any waters beyond the contiguous zone from any vessel or 
onshore or offshore facility, which vessel or facility is subject to or 
is engaged in activities under the Outer Continental Shelf Lands Act or 
the Deepwater Port Act of 1974, and (2) any discharge into any waters 
beyond the contiguous zone which contain, cover, or support any natural 
resource belonging to, appertaining to, or under the exclusive 
management authority of the United States (including resources under the 
Fishery Conservation and Management Act of 1976).
    Public vessel means a vessel owned or bareboat-chartered and 
operated by the United States, or a State or political subdivision 
thereof, or by a foreign nation, except when such vessel is engaged in 
commerce.
    Territorial seas means the belt of the seas measured from the line 
of ordinary low water along that portion of the coast which is in direct 
contact with the open sea and the line marking the seaward limit of 
inland waters, and extending seaward a distance of 3 miles.
    Vessel means every description of watercraft or other artificial 
contrivance used, or capable of being used, as a means of transportation 
on water other than a public vessel;

(i)(1)(i) through (iii) of this section. Waters identified in this 
paragraph shall not be combined with waters identified in paragraph 
(i)(1)(vi) of this section when performing a significant nexus analysis. 
If waters identified in this paragraph are also an adjacent water under 
paragraph (i)(1)(vi), they are an adjacent water and no case-specific 
significant nexus analysis is required.
    (A) Prairie potholes. Prairie potholes are a complex of glacially 
formed wetlands, usually occurring in depressions that lack permanent 
natural outlets, located in the upper Midwest.
    (B) Carolina bays and Delmarva bays. Carolina bays and Delmarva bays 
are ponded, depressional wetlands that occur along the Atlantic coastal 
plain.
    (C) Pocosins. Pocosins are evergreen shrub and tree dominated 
wetlands found predominantly along the Central Atlantic coastal plain.
    (D) Western vernal pools. Western vernal pools are seasonal wetlands 
located in parts of California and associated with topographic 
depression, soils with poor drainage, mild, wet winters and hot, dry 
summers.
    (E) Texas coastal prairie wetlands. Texas coastal prairie wetlands 
are freshwater wetlands that occur as a mosaic of depressions, ridges, 
intermound flats, and mima mound wetlands located along the Texas Gulf 
Coast.
    (viii) All waters located within the 100-year floodplain of a water 
identified in (i)(1)(i) through (iii) of this section and all waters 
located within 4,000 feet of the high tide line or ordinary high water 
mark of a water identified in paragraphs (i)(1)(i) through (v) of this 
section where they are determined on a case-specific basis to have a 
significant nexus to a water identified in paragraphs (i)(1)(i) through 
(iii) of this section. For waters determined to have a significant 
nexus, the entire water is a water of the United States if a portion is 
located within the 100-year floodplain of a water identified in 
paragraphs (i)(1)(i) through (iii) of this section or within 4,000 feet 
of the high tide line or ordinary high water mark. Waters identified in 
this paragraph shall not be combined with waters identified in paragraph 
(i)(1)(vi) of this section when performing a significant nexus analysis. 
If waters identified in this paragraph are also an adjacent water under 
paragraph (i)(1)(vi), they are an adjacent water and no case-specific 
significant nexus analysis is required.
    (2) The following are not ``waters of the United States'' even where 
they otherwise meet the terms of paragraphs (i)(1)(iv) through (viii) of 
this section.
    (i) Waste treatment systems, (other than cooling ponds meeting the 
criteria of this paragraph) are not waters of the United States.
    (ii) Prior converted cropland. Notwithstanding the determination of 
an area's status as prior converted cropland by any other Federal 
agency, for the purposes of the Clean Water Act, the final authority 
regarding Clean Water Act jurisdiction remains with EPA.
    (iii) The following ditches:
    (A) Ditches with ephemeral flow that are not a relocated tributary 
or excavated in a tributary.
    (B) Ditches with intermittent flow that are not a relocated 
tributary, excavated in a tributary, or drain wetlands.

water, into

[[Page 155]]

a water identified in paragraphs (i)(1)(i) through (iii) of this 
section.
    (iv) The following features:
    (A) Artificially irrigated areas that would revert to dry land 
should application of water to that area cease;
    (B) Artificial, constructed lakes and ponds created in dry land such 
as farm and stock watering ponds, irrigation ponds, settling basins, 
fields flooded for rice growing, log cleaning ponds, or cooling ponds;
    (C) Artificial reflecting pools or swimming pools created in dry 
land;
    (D) Small ornamental waters created in dry land;
    (E) Water-filled depressions created in dry land incidental to 
mining or construction activity, including pits excavated for obtaining 
fill, sand, or gravel that fill with water;
    (F) Erosional features, including gullies, rills, and other 
ephemeral features that do not meet the definition of tributary, non-
wetland swales, and lawfully constructed grassed waterways; and
    (G) Puddles.
    (v) Groundwater, including groundwater drained through subsurface 
drainage systems.
    (vi) Stormwater control features constructed to convey, treat, or 
store stormwater that are created in dry land.
    (vii) Wastewater recycling structures constructed in dry land; 
detention and retention basins built for wastewater recycling; 
groundwater recharge basins; percolation ponds built for wastewater 
recycling; and water distributary structures built for wastewater 
recycling.
    (3) In this paragraph, the following terms apply:
    (i) Adjacent. The term adjacent means bordering, contiguous, or 
neighboring a water identified in paragraphs (i)(1)(i) through (v) of 
this section, including waters separated by constructed dikes or 
barriers, natural river berms, beach dunes, and the like. For purposes 
of adjacency, an open water such as a pond or lake includes any wetlands 
within or abutting its ordinary high water mark. Adjacency is not 
limited to waters located laterally to a water identified in paragraphs 
(i)(1)(i) through (v) of this section. Adjacent waters also include all 
waters that connect segments of a water identified in paragraphs 
(i)(1)(i) through (v) or are located at the head of a water identified 
in paragraphs (i)(1)(i) through (v) of this section and are bordering, 
contiguous, or neighboring such water. Waters being used for established 
normal farming, ranching, and silviculture activities (33 U.S.C. 
1344(f)) are not adjacent.
    (ii) Neighboring. The term neighboring means:
    (A) All waters located within 100 feet of the ordinary high water 
mark of a water identified in paragraphs (i)(1)(i) through (v) of this 
section. The entire water is neighboring if a portion is located within 
100 feet of the ordinary high water mark;
    (B) All waters located within the 100-year floodplain of a water 
identified in paragraphs (i)(1)(i) through (v) of this section and not 
more than 1,500 feet from the ordinary high water mark of such water. 
The entire water is neighboring if a portion is located within 1,500 
feet of the ordinary high water mark and within the 100-year floodplain;
    (C) All waters located within 1,500 feet of the high tide line of a 
water identified in paragraphs (i)(1)(i) or (iii) of this section, and 
all waters within 1,500 feet of the ordinary high water mark of the 
Great Lakes. The entire water is neighboring if a portion is located 
within 1,500 feet of the high tide line or within 1,500 feet of the 
ordinary high water mark of the Great Lakes.
    (iii) Tributary and tributaries. The terms tributary and tributaries 
each mean a water that contributes flow, either directly or through 
another water (including an impoundment identified in paragraph 
(i)(1)(iv) of this section), to a water identified in paragraphs 
(i)(1)(i) through (iii) of this section that is characterized by the 
presence of the physical indicators of a bed and banks and an ordinary 
high water mark. These physical indicators demonstrate there is volume, 
frequency, and duration of flow sufficient to create a bed and banks and 
an ordinary high water mark, and thus to qualify as a tributary. A 
tributary can be a natural, man-altered, or man-made water and includes 
waters such as rivers, streams, canals, and ditches not

[[Page 156]]

excluded under paragraph (i)(2) of this section. A water that otherwise 
qualifies as a tributary under this definition does not lose its status 
as a tributary if, for any length, there are one or more constructed 
breaks (such as bridges, culverts, pipes, or dams), or one or more 
natural breaks (such as wetlands along the run of a stream, debris 
piles, boulder fields, or a stream that flows underground) so long as a 
bed and banks and an ordinary high water mark can be identified upstream 
of the break. A water that otherwise qualifies as a tributary under this 
definition does not lose its status as a tributary if it contributes 
flow through a water of the United States that does not meet the 
definition of tributary or through a non-jurisdictional water to a water 
identified in paragraphs (i)(1)(i) through (iii) of this section.
    (iv) Wetlands. The term wetlands means those areas that are 
inundated or saturated by surface or groundwater at a frequency and 
duration sufficient to support, and that under normal circumstances do 
support, a prevalence of vegetation typically adapted for life in 
saturated soil conditions. Wetlands generally include swamps, marshes, 
bogs, and similar areas.
    (v) Significant nexus. The term significant nexus means that a 
water, including wetlands, either alone or in combination with other 
similarly situated waters in the region, significantly affects the 
chemical, physical, or biological integrity of a water identified in 
paragraphs (i)(1)(i) through (iii) of this section. The term ``in the 
region'' means the watershed that drains to the nearest water identified 
in paragraphs (i)(1)(i) through (iii) of this section. For an effect to 
be significant, it must be more than speculative or insubstantial. 
Waters are similarly situated when they function alike and are 
sufficiently close to function together in affecting downstream waters. 
For purposes of determining whether or not a water has a significant 
nexus, the water's effect on downstream (i)(1)(i) through (iii) waters 
shall be assessed by evaluating the aquatic functions identified in 
paragraphs (i)(3)(v)(A) through (I) of this section. A water has a 
significant nexus when any single function or combination of functions 
performed by the water, alone or together with similarly situated waters 
in the region, contributes significantly to the chemical, physical, or 
biological integrity of the nearest water identified in paragraphs 
(i)(1)(i) through (iii) of this section. Functions relevant to the 
significant nexus evaluation are the following:
    (A) Sediment trapping,
    (B) Nutrient recycling,
    (C) Pollutant trapping, transformation, filtering, and transport,
    (D) Retention and attenuation of flood waters,
    (E) Runoff storage,
    (F) Contribution of flow,
    (G) Export of organic matter,
    (H) Export of food resources, and
    (I) Provision of life cycle dependent aquatic habitat (such as 
foraging, feeding, nesting, breeding, spawning, or use as a nursery 
area) for species located in a water identified in paragraphs (i)(1)(i) 
through (iii) of this section.
    (vi) Ordinary high water mark. The term ordinary high water mark 
means that line on the shore established by the fluctuations of water 
and indicated by physical characteristics such as a clear, natural line 
impressed on the bank, shelving, changes in the character of soil, 
destruction of terrestrial vegetation, the presence of litter and 
debris, or other appropriate means that consider the characteristics of 
the surrounding areas.
    (vii) High tide line. The term high tide line means the line of 
intersection of the land with the water's surface at the maximum height 
reached by a rising tide. The high tide line may be determined, in the 
absence of actual data, by a line of oil or scum along shore objects, a 
more or less continuous deposit of fine shell or debris on the foreshore 
or berm, other physical markings or characteristics, vegetation lines, 
tidal gages, or other suitable means that delineate the general height 
reached by a rising tide. The line encompasses spring high tides and 
other high tides that occur with periodic frequency but does not include 
storm surges in which there is a departure from the normal or predicted 
reach of the tide due to the piling up of water against a coast by 
strong winds such as those accompanying a hurricane or other intense 
storm.

    (j) Process waste water means any water which, during manufacturing 
or processing, comes into direct contact with or results from the 
production or use of any raw material, intermediate product, finished 
product, byproduct, or waste product.

such permit;
    (3) Continuous or anticipated intermittent discharges from a point 
source, identified in a permit or permit application under section 402 
of this Act, which are caused by events occurring within the scope of 
the relevant operating or treatment systems; or
    (b) A discharge is ``in compliance with a permit issued under 
section 402 of this Act'' if the permit contains an effluent limitation 
specifically applicable to the substance discharged or an effluent 
limitation applicable to another waste parameter which has been 
specifically identified in the permit as intended to limit such 
substance, and the discharge is in compliance with the effluent 
limitation.
    (c) A discharge results ``from circumstances identified, reviewed 
and made a part of the public record with respect to a permit issued or

    (3) The treatment to be provided is in place.
    (d) A discharge is a ``continuous or anticipated intermittent 
discharge from a point source, identified in a permit or permit 
application under section 402 of this Act, and caused by events 
occurring within the scope of the relevant operating or treatment 
systems,'' whether or not the discharge is in compliance with the 
permit, if:
    (1) The hazardous substance is discharged from a point source for 
which a valid permit exists or for which a permit application has been 
submitted; and
    (2) The discharge of the hazardous substance results from:
    (i) The contamination of noncontact cooling water or storm water, 
provided that such cooling water or storm water

[[Page 161]]

quantities to a POTW, where the discharge originates from a mobile 
source, except where such source has contracted with, or otherwise 
received written permission from the owners or operators of the POTW to 
discharge that quantity, and the mobile source can show that prior to 
accepting the substance from an industrial discharger, the substance had 
been treated to comply with any effluent limitation under sections 301, 
302 or 306 or pretreatment standard under section 307 applicable to that 
facility.



Sec. 117.14  Demonstration projects.

    Notwithstanding any other provision of this part, the Administrator 
of the Environmental Protection Agency may, on a case-by-case basis, 
allow the discharge of designated hazardous substances in connection 
with research or demonstration projects relating to the prevention, 
control, or abatement of hazardous substance pollution. The 
Administrator will allow such a discharge only where he determines that 
the expected environmental benefit from such a discharge will outweigh 
the potential hazard associated with the discharge.



         Subpart C_Notice of Discharge of a Reportable Quantity



Sec. 117.21  Notice.

    Any person in charge of a vessel or an onshore or an offshore 
facility shall, as soon as he has knowledge of any discharge of a

quantities equal to or exceeding in any 24-hour period the reportable 
quantity determined by this part, immediately notify the appropriate 
agency of the United States Government of such discharge. Notice shall 
be given in accordance with such procedures as the Secretary of 
Transportation has set forth in 33 CFR 153.203. This provision applies 
to all discharges not specifically excluded or reserved by another 
section of these regulations.



Sec. 117.23  Liabilities for removal.

    In any case where a substance designated as hazardous in 40 CFR part 
116 is discharged from any vessel or onshore or offshore facility in a 
quantity equal to or exceeding the reportable quantity determined by 
this part, the owner, operator or person in charge will be liable, 
pursuant to section 311 (f) and (g) of the Act, to the United States 
Government for the actual costs incurred in the removal of such 
substance, subject only to the defenses and monetary limitations 
enumerated in section 311 (f) and (g) of the Act.

The Administrator may act to mitigate the damage to the public health or 
welfare caused by a discharge and the cost of such mitigation shall be 
considered a cost incurred under section 311(c) for the removal of that 
substance by the United States Government.

determines that such a hearing is necessary or appropriate.



Sec. 121.24  Certification.

    If, after considering the complete description, the record of a 
hearing, if any, held pursuant to Sec. 121.23, and such other 
information and data as the Regional Administrator deems relevant, the 
Regional Administrator determines that there is reasonable assurance 
that the proposed activity will not result in a violation of applicable 
water quality standards, he shall so certify. If the Regional 
Administrator determines that no water quality standards are applicable 
to the waters which might be affected by the proposed activity, he shall 
so notify the applicant and the licensing or permitting agency in 
writing and shall provide the licensing or permitting agency with 
advice, suggestions, and recommendations with respect to conditions to 
be incorporated in any license or permit to achieve compliance with the 
purpose of this Act. In such case, no certification shall be required.



Sec. 121.25  Adoption of new water quality standards.

    (a) In any case where:
    (1) A license or permit was issued without certification due to the 
absence of applicable water quality standards; and
    (2) Water quality standards applicable to the waters into which the 
licensed or permitted activity may discharge are subsequently 
established; and
    (3) The Administrator is the certifying agency because:
    (i) No State or interstate agency has authority to certify; or
    (ii) Such new standards were promulgated by the Administrator 
pursuant to section 10(c)(2) of the Act; and
    (4) The Regional Administrator determines that such uncertified 
activity is violating water quality standards;

Then the Regional Administrator shall notify the licensee or permittee 
of such violation, including his recommendations as to actions necessary 
for compliance. If the licensee or permittee fails within 6 months of 
the date of such notice to take action which in the opinion of the 
Regional Administrator will result in compliance with applicable water 
quality standards, the Regional Administrator shall notify the licensing 
or permitting agency that the licensee or permittee has failed, after 
reasonable notice, to comply with such standards and that suspension of 
the applicable license or permit is required by section 21(b)(9)(B) of 
the Act.
    (b) Where a license or permit is suspended pursuant to paragraph (a) 
of this section, and where the licensee or permittee subsequently takes 
action which in the Regional Administrator's opinion will result in 
compliance with applicable water quality standards, the Regional 
Administrator shall then notify the licensing or permitting agency that 
there is reasonable assurance that the licensed or permitted activity 
will comply with applicable water quality standards.



Sec. 121.26  Inspection of facility or activity before operation.

    Where any facility or activity has received certification pursuant 
to Sec. 121.24 in connection with the issuance of a license or permit 
for construction, and where such facility or activity is not required to 
obtain an operating license or permit, the Regional Administrator or his 
representative, prior to the initial operation of such facility or 
activity, shall be afforded the opportunity to inspect such facility or 
activity for the purpose of determining if the manner in which such 
facility or activity will be operated or conducted will violate 
applicable water quality standards.



Sec. 121.27  Notification to licensing or permitting agency.

    If the Regional Administrator, after an inspection pursuant to Sec. 
121.26, determines that operation of the proposed facility or activity 
will violate applicable water quality standards, he shall so notify the 
applicant and the licensing or permitting agency, including his 
recommendations as to remedial measures necessary to bring the operation 
of the proposed facility into compliance with such standards.

[[Page 166]]



Sec. 121.28  Termination of suspension.

    Where a licensing or permitting agency, following a public hearing, 
suspends a license or permit after receiving the Regional 
Administrator's notice and recommendation pursuant to Sec. 121.27, the 
applicant may submit evidence to the Regional Administrator that the 
facility or activity or the operation or conduct thereof has been 
modified so as not to violate water quality standards. If the Regional 
Administrator determines that water quality standards will not be 
violated, he shall so notify the licensing or permitting agency.



                         Subpart D_Consultations



Sec. 121.30  Review and advice.

    The Regional Administrator may, and upon request shall, provide 
licensing and permitting agencies with determinations, definitions and 
interpretations with respect to the meaning and content of water quality 
standards where they have been federally approved under section 10 of 
the Act, and findings with respect to the application of all applicable 
water quality standards in particular cases and in specific 
circumstances relative to an activity for which a license or permit is 
sought. The Regional Administrator may, and upon request shall, also 
advise licensing and permitting agencies as to the status of compliance 
by dischargers with the conditions and requirements of applicable water 
quality standards. In cases where an activity for which a license or 
permit is sought will affect water quality, but for which there are no 
applicable water quality standards, the Regional Administrator may 
advise licensing or permitting agencies with respect to conditions of 
such license or permit to achieve compliance with the purpose of the 
Act.

         Subpart A_Definitions and General Program Requirements



Sec. 122.1  Purpose and scope.

    (a) Coverage. (1) The regulatory provisions contained in this part 
and parts 123, and 124 of this chapter implement the National Pollutant 
Discharge Elimination System (NPDES) Program under sections 318, 402, 
and 405 of the Clean Water Act (CWA) (Public Law 92-500, as amended, 33 
U.S.C. 1251 et seq.)
    (2) These provisions cover basic EPA permitting requirements (this 
part 122), what a State must do to obtain approval to operate its 
program in lieu of a Federal program and minimum requirements for 
administering the approved State program (part 123 of this chapter), and 
procedures for EPA processing of permit applications and appeals (part 
124 of this chapter).
    (3) These provisions also establish the requirements for public 
participation in EPA and State permit issuance and enforcement and 
related variance proceedings, and in the approval of State NPDES 
programs. These provisions carry out the purposes of the public 
participation requirements of part 25 of this chapter, and supersede the 
requirements of that part as they apply to actions covered under this 
part and parts 123, and 124 of this chapter.
    (4) Regulatory provisions in Parts 125, 129, 133, 136 of this 
chapter and 40 CFR subchapter N and subchapter O of this chapter also 
implement the NPDES permit program.
    (5) Certain requirements set forth in parts 122 and 124 of this 
chapter are made applicable to approved State programs by reference in 
part 123 of this chapter. These references are set forth in Sec. 123.25 
of this chapter. If a section or paragraph of part 122 or 124 of this

[[Page 168]]

chapter is applicable to States, through reference in Sec. 123.25 of 
this chapter, that fact is signaled by the following words at the end of 
the section or paragraph heading: (Applicable to State programs, see 
Sec. 123.25 of this chapter). If these words are absent, the section 
(or paragraph) applies only to EPA administered permits. Nothing in this 
part and parts 123, or 124 of this chapter precludes more stringent 
State regulation of any activity covered by the regulations in 40 CFR 
parts 122, 123, and 124, whether or not under an approved State program.
    (b) Scope of the NPDES permit requirement. (1) The NPDES program 
requires permits for the discharge of ``pollutants'' from any ``point 
source'' into ``waters of the United States.'' The terms ``pollutant'', 
``point source'' and ``waters of the United States'' are defined at 
Sec. 122.2.
    (2) The permit program established under this part also applies to 
owners or operators of any treatment works treating domestic sewage, 
whether or not the treatment works is otherwise required to obtain an 
NPDES permit, unless all requirements implementing section 405(d) of the 
CWA applicable to the treatment works treating domestic sewage are 
included in a permit issued under the appropriate provisions of subtitle 
C of the Solid Waste Disposal Act, Part C of the Safe Drinking Water 
Act, the Marine Protection, Research, and Sanctuaries Act of 1972, or 
the Clean Air Act, or under State permit programs approved by the 
Administrator as adequate to assure compliance with section 405 of the 
CWA.
    (3) The Regional Administrator may designate any person subject to 
the standards for sewage sludge use and disposal as a ``treatment works 
treating domestic sewage'' as defined in Sec. 122.2, where the Regional 
Administrator finds that a permit is necessary to protect public health 
and the environment from the adverse effects of sewage sludge or to 
ensure compliance with the technical standards for sludge use and 
disposal developed under CWA section 405(d). Any person designated as a 
``treatment works treating domestic sewage'' shall submit an application 
for a permit under Sec. 122.21 within 180 days of being notified by the 
Regional Administrator that a permit is required. The Regional 
Administrator's decision to designate a person as a ``treatment works 
treating domestic sewage'' under this paragraph shall be stated in the 
fact sheet or statement of basis for the permit.

    [Note to Sec. 122.1: Information concerning the NPDES program and 
its regulations can be obtained by contacting the Water Permits 
Division(4203), Office of Wastewater Management, U.S.E.P.A., Ariel Rios

Sec. 122.2  Definitions.

    The following definitions apply to parts 122, 123, and 124. Terms 
not defined in this section have the meaning given by CWA. When a 
defined term appears in a definition, the defined term is sometimes 
placed in quotation marks as an aid to readers.
    Administrator means the Administrator of the United States 
Environmental Protection Agency, or an authorized representative.
    Animal feeding operation is defined at Sec. 122.23.
    Applicable standards and limitations means all State, interstate, 
and federal standards and limitations to which a ``discharge,'' a 
``sewage sludge use or disposal practice,'' or a related activity is 
subject under the CWA, including ``effluent limitations,'' water quality 
standards, standards of performance, toxic effluent standards or 
prohibitions, ``best management practices,'' pretreatment standards, and 
``standards for sewage sludge use or disposal'' under sections 301, 302, 
303, 304, 306, 307, 308, 403 and 405 of CWA.
    Application means the EPA standard national forms for applying for a 
permit, including any additions, revisions or modifications to the 
forms; or forms approved by EPA for use in ``approved States,'' 
including any approved modifications or revisions.
    Approved program or approved State means a State or interstate 
program which has been approved or authorized by EPA under part 123.
    Aquaculture project is defined at Sec. 122.25.

[[Page 169]]

    Average monthly discharge limitation means the highest allowable 
average of ``daily discharges'' over a calendar month, calculated as the 
sum of all ``daily discharges'' measured during a calendar month divided 
by the number of ``daily discharges'' measured during that month.
    Average weekly discharge limitation means the highest allowable 
average of ``daily discharges'' over a calendar week, calculated as the 
sum of all ``daily discharges'' measured during a calendar week divided 
by the number of ``daily discharges'' measured during that week.
    Best management practices (``BMPs'') means schedules of activities, 
prohibitions of practices, maintenance procedures, and other management 
practices to prevent or reduce the pollution of ``waters of the United 
States.'' BMPs also include treatment requirements, operating 
procedures, and practices to control plant site runoff, spillage or 
leaks, sludge or waste disposal, or drainage from raw material storage.
    BMPs means ``best management practices.''
    Class I sludge management facility means any POTW identified under 
40 CFR 403.8(a) as being required to have an approved pretreatment 
program (including such POTWs located in a State that has elected to 
assume local program responsibilities pursuant to 40 CFR 403.10(e)) and 
any other treatment works treating domestic sewage classified as a Class 
I sludge management facility by the Regional Administrator, or, in the 
case of approved State programs, the Regional Administrator in 
conjunction with the State Director, because of the potential for its 
sludge use or disposal practices to adversely affect public health and 
the environment.
    Bypass is defined at Sec. 122.41(m).
    Concentrated animal feeding operation is defined at Sec. 122.23.
    Concentrated aquatic animal feeding operation is defined at Sec. 
122.24.
    Contiguous zone means the entire zone established by the United 
States under Article 24 of the Convention on the Territorial Sea and the 
Contiguous Zone.
    Continuous discharge means a ``discharge'' which occurs without 
interruption throughout the operating hours of the facility, except for 
infrequent shutdowns for maintenance, process changes, or other similar 
activities.
    CWA means the Clean Water Act (formerly referred to as the Federal 
Water Pollution Control Act or Federal Water Pollution Control Act 
Amendments of 1972) Public Law 92-500, as amended by Public Law 95-217, 
Public Law 95-576, Public Law 96-483 and Public Law 97-117, 33 U.S.C. 
1251 et seq.
    CWA and regulations means the Clean Water Act (CWA) and applicable 
regulations promulgated thereunder. In the case of an approved State 
program, it includes State program requirements.
    Daily discharge means the ``discharge of a pollutant'' measured 
during a calendar day or any 24-hour period that reasonably represents 
the calendar day for purposes of sampling. For pollutants with 
limitations expressed in units of mass, the ``daily discharge'' is 
calculated as the total mass of the pollutant discharged over the day. 
For pollutants with limitations expressed in other units of measurement, 
the ``daily discharge'' is calculated as the average measurement of the 
pollutant over the day.
    Direct discharge means the ``discharge of a pollutant.''
    Director means the Regional Administrator or the State Director, as 
the context requires, or an authorized representative. When there is no 
``approved State program,'' and there is an EPA administered program, 
``Director'' means the Regional Administrator. When there is an approved 
State program, ``Director'' normally means the State Director. In some 
circumstances, however, EPA retains the authority to take certain 
actions even when there is an approved State program. (For example, when 
EPA has issued an NPDES permit prior to the approval of a State program, 
EPA may retain jurisdiction over that permit after program approval, see 
Sec. 123.1.) In such cases, the term ``Director'' means the Regional 
Administrator and not the State Director.
    Discharge when used without qualification means the ``discharge of a 
pollutant.''
    Discharge of a pollutant means:

[[Page 170]]

    (a) Any addition of any ``pollutant'' or combination of pollutants 
to ``waters of the United States'' from any ``point source,'' or
    (b) Any addition of any pollutant or combination of pollutants to 
the waters of the ``contiguous zone'' or the ocean from any point source 
other than a vessel or other floating craft which is being used as a 
means of transportation.

This definition includes additions of pollutants into waters of the 
United States from: surface runoff which is collected or channelled by 
man; discharges through pipes, sewers, or other conveyances owned by a 
State, municipality, or other person which do not lead to a treatment 
works; and discharges through pipes, sewers, or other conveyances, 
leading into privately owned treatment works. This term does not include 
an addition of pollutants by any ``indirect discharger.''
    Discharge Monitoring Report (``DMR'') means the EPA uniform national 
form, including any subsequent additions, revisions, or modifications 
for the reporting of self-monitoring results by permittees. DMRs must be 
used by ``approved States'' as well as by EPA. EPA will supply DMRs to 
any approved State upon request. The EPA national forms may be modified 
to substitute the State Agency name, address, logo, and other similar 
information, as appropriate, in place of EPA's.
    DMR means ``Discharge Monitoring Report.''
    Draft permit means a document prepared under Sec. 124.6 indicating 
the Director's tentative decision to issue or deny, modify, revoke and 
reissue, terminate, or reissue a ``permit.'' A notice of intent to 
terminate a permit, and a notice of intent to deny a permit, as 
discussed in Sec. 124.5, are types of ``draft permits.'' A denial of a 
request for modification, revocation and reissuance, or termination, as 
discussed in Sec. 124.5, is not a ``draft permit.'' A ``proposed 
permit'' is not a ``draft permit.''
    Effluent limitation means any restriction imposed by the Director on 
quantities, discharge rates, and concentrations of ``pollutants'' which 
are ``discharged'' from ``point sources'' into ``waters of the United 
States,'' the waters of the ``contiguous zone,'' or the ocean.
    Effluent limitations guidelines means a regulation published by the 
Administrator under section 304(b) of CWA to adopt or revise ``effluent 
limitations.''
    Environmental Protection Agency (``EPA'') means the United States 
Environmental Protection Agency.
    EPA means the United States ``Environmental Protection Agency.''
    Facility or activity means any NPDES ``point source'' or any other 
facility or activity (including land or appurtenances thereto) that is 
subject to regulation under the NPDES program.
    Federal Indian reservation means all land within the limits of any 
Indian reservation under the jurisdiction of the United States 
Government, notwithstanding the issuance of any patent, and including 
rights-of-way running through the reservation.
    General permit means an NPDES ``permit'' issued under Sec. 122.28 
authorizing a category of discharges under the CWA within a geographical 
area.
    Hazardous substance means any substance designated under 40 CFR part 
116 pursuant to section 311 of CWA.
    Indian country means:
    (1) All land within the limits of any Indian reservation under the 
jurisdiction of the United States Government, notwithstanding the 
issuance of any patent, and, including rights-of-way running through the 
reservation;
    (2) All dependent Indian communities with the borders of the United 
States whether within the originally or subsequently acquired territory 
thereof, and whether within or without the limits of a state; and
    (3) All Indian allotments, the Indian titles to which have not been 
extinguished, including rights-of-way running through the same.
    Indian Tribe means any Indian Tribe, band, group, or community 
recognized by the Secretary of the Interior and exercising governmental 
authority over a Federal Indian reservation.
    Indirect discharger means a nondomestic discharger introducing 
``pollutants'' to a ``publicly owned treatment works.''
    Individual control strategy is defined at 40 CFR 123.46(c).

[[Page 171]]

    Interstate agency means an agency of two or more States established 
by or under an agreement or compact approved by the Congress, or any 
other agency of two or more States having substantial powers or duties 
pertaining to the control of pollution as determined and approved by the 
Administrator under the CWA and regulations.
    Major facility means any NPDES ``facility or activity'' classified 
as such by the Regional Administrator, or, in the case of ``approved 
State programs,'' the Regional Administrator in conjunction with the 
State Director.
    Maximum daily discharge limitation means the highest allowable 
``daily discharge.''
    Municipality means a city, town, borough, county, parish, district, 
association, or other public body created by or under State law and 
having jurisdiction over disposal of sewage, industrial wastes, or other 
wastes, or an Indian tribe or an authorized Indian tribal organization, 
or a designated and approved management agency under section 208 of CWA.
    Municipal separate storm sewer system is defined at Sec. 122.26 
(b)(4) and (b)(7).
    National Pollutant Discharge Elimination System (NPDES) means the 
national program for issuing, modifying, revoking and reissuing, 
terminating, monitoring and enforcing permits, and imposing and 
enforcing pretreatment requirements, under sections 307, 402, 318, and 
405 of CWA. The term includes an ``approved program.''
    New discharger means any building, structure, facility, or 
installation:
    (a) From which there is or may be a ``discharge of pollutants;''
    (b) That did not commence the ``discharge of pollutants'' at a 
particular ``site'' prior to August 13, 1979;
    (c) Which is not a ``new source;'' and
    (d) Which has never received a finally effective NDPES permit for 
discharges at that ``site.''

This definition includes an ``indirect discharger'' which commences 
discharging into ``waters of the United States'' after August 13, 1979. 
It also includes any existing mobile point source (other than an 
offshore or coastal oil and gas exploratory drilling rig or a coastal 
oil and gas developmental drilling rig) such as a seafood processing 
rig, seafood processing vessel, or aggregate plant, that begins 
discharging at a ``site'' for which it does not have a permit; and any 
offshore or coastal mobile oil and gas exploratory drilling rig or 
coastal mobile oil and gas developmental drilling rig that commences the 
discharge of pollutants after August 13, 1979, at a ``site'' under EPA's 
permitting jurisdiction for which it is not covered by an individual or 
general permit and which is located in an area determined by the 
Regional Administrator in the issuance of a final permit to be an area 
or biological concern. In determining whether an area is an area of 
biological concern, the Regional Administrator shall consider the 
factors specified in 40 CFR 125.122(a) (1) through (10).

An offshore or coastal mobile exploratory drilling rig or coastal mobile 
developmental drilling rig will be considered a ``new discharger'' only 
for the duration of its discharge in an area of biological concern.

    (iii) The territorial seas;
    (iv) All impoundments of waters otherwise identified as waters of 
the United States under this section;
    (v) All tributaries, as defined in paragraph (3)(iii) of this 
section, of waters identified in paragraphs (1)(i) through (iii) of this 
section;
    (vi) All waters adjacent to a water identified in paragraphs (1)(i) 
through (v) of this definition, including wetlands, ponds, lakes, 
oxbows, impoundments, and similar waters;
    (vii) All waters in paragraphs (1)(vii)(A) through (E) of this 
definition where they are determined, on a case-specific basis, to have 
a significant nexus to a water identified in paragraphs (1)(i) through 
(iii) of this definition. The waters identified in each of paragraphs 
(1)(vii)(A) through (E) of this definition are similarly situated and 
shall be combined, for purposes of a significant nexus analysis, in the 
watershed that drains to the nearest water identified in paragraphs 
(1)(i) through (iii) of this definition. Waters identified in this 
paragraph shall not be combined with waters identified in paragraph 
(1)(vi) of this definition when performing a significant nexus analysis. 
If waters identified in this paragraph are also an adjacent water under 
paragraph (1)(vi), they are an adjacent water and no case-specific 
significant nexus analysis is required.
    (A) Prairie potholes. Prairie potholes are a complex of glacially 
formed wetlands, usually occurring in depressions that lack permanent 
natural outlets, located in the upper Midwest.
    (B) Carolina bays and Delmarva bays. Carolina bays and Delmarva bays

    (viii) All waters located within the 100-year floodplain of a water 
identified in paragraphs (1)(i) through (iii) of this definition and all 
waters located within 4,000 feet of the high tide line or ordinary high 
water mark of a water identified in paragraphs (1)(i) through (v) of 
this definition where they are determined on a case-specific basis to 
have a significant nexus to a water identified in paragraphs (1)(i) 
through (v) of this definition. For waters determined to have a 
significant nexus, the entire water is a water of the United States if a 
portion is located within the 100-year floodplain of a water identified 
in (1)(i)

[[Page 175]]

through (iii) of this definition or within 4,000 feet of the high tide 
line or ordinary high water mark. Waters identified in this paragraph 
shall not be combined with waters identified in paragraph (1)(vi) of 
this definition when performing a significant nexus analysis. If waters 
identified in this paragraph are also an adjacent water under paragraph 
(1)(vi), they are an adjacent water and no case-specific significant 
nexus analysis is required.
    (2) The following are not ``waters of the United States'' even where 
they otherwise meet the terms of paragraphs (1)(iv) through (viii) of 
this definition.
    (i) Waste treatment systems, including treatment ponds or lagoons

applies only to manmade bodies of water which neither were originally 
created in waters of the United States (such as disposal area in 
wetlands) nor resulted from the impoundment of waters of the United 
States. [See Note 1 of this section.]
    (ii) Prior converted cropland. Notwithstanding the determination of 
an area's status as prior converted cropland by any other Federal 
agency, for the purposes of the Clean Water Act, the final authority 
regarding Clean Water Act jurisdiction remains with EPA.
    (iii) The following ditches:
    (A) Ditches with ephemeral flow that are not a relocated tributary 
or excavated in a tributary.
    (B) Ditches with intermittent flow that are not a relocated 
tributary, excavated in a tributary, or drain wetlands.
    (C) Ditches that do not flow, either directly or through another 
water, into a water identified in paragraphs (1)(i) through (iii) of 
this definition.
    (iv) The following features:
    (A) Artificially irrigated areas that would revert to dry land 
should application of water to that area cease;
    (B) Artificial, constructed lakes and ponds created in dry land such 
as farm and stock watering ponds, irrigation ponds, settling basins, 
fields flooded for rice growing, log cleaning ponds, or cooling ponds;
    (C) Artificial reflecting pools or swimming pools created in dry 
land;
    (D) Small ornamental waters created in dry land;
    (E) Water-filled depressions created in dry land incidental to 
mining or construction activity, including pits excavated for obtaining 
fill, sand, or gravel that fill with water;
    (F) Erosional features, including gullies, rills, and other

groundwater recharge basins; percolation ponds built for wastewater 
recycling; and water distributary structures built for wastewater 
recycling.
    (3) In this definition, the following terms apply:
    (i) Adjacent. The term adjacent means bordering, contiguous, or 
neighboring a water identified in paragraphs (1)(i) through (v) of this 
definition, including waters separated by constructed dikes or barriers, 
natural river berms, beach dunes, and the like. For purposes of 
adjacency, an open water such as a pond or lake includes any wetlands 
within or abutting its ordinary high water mark. Adjacency is not 
limited to waters located laterally to a water identified in paragraphs 
(1)(i) through (v) of this definition. Adjacent waters also include all 
waters that connect segments of a water identified in paragraphs (1)(i) 
through (v) or are located at the head of a water identified in 
paragraphs (1)(i) through (v) of this definition and are bordering, 
contiguous, or neighboring such water. Waters being used for established 
normal farming, ranching, and silviculture activities (33 U.S.C. 
1344(f)) are not adjacent.
    (ii) Neighboring. The term neighboring means:

[[Page 176]]

    (A) All waters located within 100 feet of the ordinary high water 
mark of a water identified in paragraphs (1)(i) through (v) of this 
definition. The entire water is neighboring if a portion is located 
within 100 feet of the ordinary high water mark;
    (B) All waters located within the 100-year floodplain of a water 
identified in paragraphs (1)(i) through (v) of this definition and not 
more than 1,500 feet from the ordinary high water mark of such water. 
The entire water is neighboring if a portion is located within 1,500 
feet of the ordinary high water mark and within the 100-year floodplain;
    (C) All waters located within 1,500 feet of the high tide line of a 
water identified in paragraphs (1)(i) or (iii) of this definition, and 
all waters within 1,500 feet of the ordinary high water mark of the 
Great Lakes. The entire water is neighboring if a portion is located 
within 1,500 feet of the high tide line or within 1,500 feet of the 
ordinary high water mark of the Great Lakes.
    (iii) Tributary and tributaries. The terms tributary and tributaries 
each mean a water that contributes flow, either directly or through 
another water (including an impoundment identified in paragraph (1)(iv) 
of this definition), to a water identified in paragraphs (1)(i) through 
(iii) of this definition that is characterized by the presence of the 
physical indicators of a bed and banks and an ordinary high water mark. 
These physical indicators demonstrate there is volume, frequency, and 
duration of flow sufficient to create a bed and banks and an ordinary 
high water mark, and thus to qualify as a tributary. A tributary can be 
a natural, man-altered, or man-made water and includes waters such as 
rivers, streams, canals, and ditches not excluded under paragraph (2) of 
this definition. A water that otherwise qualifies as a tributary under 
this definition does not lose its status as a tributary if, for any 
length, there are one or more constructed breaks (such as bridges, 
culverts, pipes, or dams), or one or more natural breaks (such as 
wetlands along the run of a stream, debris piles, boulder fields, or a 
stream that flows underground) so long as a bed and banks and an 
ordinary high water mark can be identified upstream of the break. A 
water that otherwise qualifies as a tributary under this definition does 
not lose its status as a tributary if it contributes flow through a 
water of the United States that does not meet the definition of 
tributary or through a non-jurisdictional water to a water identified in 
paragraphs (1)(i) through (iii) of this definition.
    (iv) Wetlands. The term wetlands means those areas that are 
inundated or saturated by surface or groundwater at a frequency and 
duration sufficient to support, and that under normal circumstances do 
support, a prevalence of vegetation typically adapted for life in 
saturated soil conditions. Wetlands generally include swamps, marshes, 
bogs, and similar areas.
    (v) Significant nexus. The term significant nexus means that a 
water, including wetlands, either alone or in combination with other 
similarly situated waters in the region, significantly affects the 
chemical, physical, or biological integrity of a water identified in 
paragraphs (1)(i) through (iii) of this definition. The term ``in the 
region'' means the watershed that drains to the nearest water identified 
in paragraphs (1)(i) through (iii) of this definition. For an effect to 
be significant, it must be more than speculative or insubstantial. 
Waters are similarly situated when they function alike and are 
sufficiently close to function together in affecting downstream waters. 
For purposes of determining whether or not a water has a significant 
nexus, the water's effect on downstream (1)(i) through (iii) waters 
shall be assessed by evaluating the aquatic functions identified in 
paragraphs (3)(v)(A) through (I) of this definition. A water has a 
significant nexus when any single function or combination of functions 
performed by the water, alone or together with similarly situated waters 
in the region, contributes significantly to the chemical, physical, or 
biological integrity of the nearest water identified in paragraphs 
(1)(i) through (iii) of this definition. Functions relevant to the 
significant nexus evaluation are the following:
    (A) Sediment trapping,
    (B) Nutrient recycling,

[[Page 177]]

    (C) Pollutant trapping, transformation, filtering, and transport,
    (D) Retention and attenuation of flood waters,
    (E) Runoff storage,
    (F) Contribution of flow,
    (G) Export of organic matter,
    (H) Export of food resources, and
    (I) Provision of life cycle dependent aquatic habitat (such as 
foraging, feeding, nesting, breeding, spawning, or use as a nursery 
area) for species located in a water identified in paragraphs (1)(i) 
through (iii) of this definition.
    (vi) Ordinary high water mark. The term ordinary high water mark 
means that line on the shore established by the fluctuations of water 
and indicated by physical characteristics such as a clear, natural line 
impressed on the bank, shelving, changes in the character of soil, 
destruction of terrestrial vegetation, the presence of litter and 
debris, or other appropriate means that consider the characteristics of 
the surrounding areas.
    (vii) High tide line. The term high tide line means the line of 
intersection of the land with the water's surface at the maximum height 
reached by a rising tide. The high tide line may be determined, in the 
absence of actual data, by a line of oil or scum along shore objects, a 
more or less continuous deposit of fine shell or debris on the foreshore 
or berm, other physical markings or characteristics, vegetation lines, 
tidal gages, or other suitable means that delineate the general height 
reached by a rising tide. The line encompasses spring high tides and 
other high tides that occur with periodic frequency but does not include 
storm surges in which there is a departure from the normal or predicted 
reach of the tide due to the piling up of water against a coast by 
strong winds such as those accompanying a hurricane or other intense 
storm.
    Whole effluent toxicity means the aggregate toxic effect of an 
effluent measured directly by a toxicity test.

Sec. 122.3  Exclusions.

    The following discharges do not require NPDES permits:
    (a) Any discharge of sewage from vessels, effluent from properly 
functioning marine engines, laundry, shower, and galley sink wastes, or 
any other discharge incidental to the normal operation of a vessel. This 
exclusion does not apply to rubbish, trash, garbage, or other such 
materials discharged overboard; nor to other discharges when the vessel 
is operating in a capacity other than as a means of transportation such 
as when used as an energy or mining facility, a storage facility or a 
seafood processing facility, or when secured to a storage facility or a 
seafood processing facility, or when secured to the bed of the ocean, 
contiguous zone or waters of the United States for the purpose of 
mineral or oil exploration or development.
    (b) Discharges of dredged or fill material into waters of the United 
States which are regulated under section 404 of CWA.
    (c) The introduction of sewage, industrial wastes or other 
pollutants into publicly owned treatment works by indirect dischargers. 
Plans or agreements to switch to this method of disposal in the future 
do not relieve dischargers of the obligation to have and comply with

[[Page 178]]

permits until all discharges of pollutants to waters of the United 
States are eliminated. (See also Sec. 122.47(b)). This exclusion does 
not apply to the introduction of pollutants to privately owned treatment 
works or to other discharges through pipes, sewers, or other conveyances 
owned by a State, municipality, or other party not leading to treatment 
works.
    (d) Any discharge in compliance with the instructions of an On-Scene 
Coordinator pursuant to 40 CFR part 300 (The National Oil and Hazardous 
Substances Pollution Contingency Plan) or 33 CFR 153.10(e) (Pollution by 
Oil and Hazardous Substances).
    (e) Any introduction of pollutants from non point-source 
agricultural and silvicultural activities, including storm water runoff 
from orchards, cultivated crops, pastures, range lands, and forest 
lands, but not discharges from concentrated animal feeding operations as 
defined in Sec. 122.23, discharges from concentrated aquatic animal 
production facilities as defined in Sec. 122.24, discharges to 
aquaculture projects as defined in Sec. 122.25, and discharges from 
silvicultural point sources as defined in Sec. 122.27.
    (f) Return flows from irrigated agriculture.
    (g) Discharges into a privately owned treatment works, except as the 
Director may otherwise require under Sec. 122.44(m).
    (h) [Reserved]
    (i) Discharges from a water transfer. Water transfer means an 
activity that conveys or connects waters of the United States without 
subjecting the transferred water to intervening industrial, municipal, 
or commercial use. This exclusion does not apply to pollutants 
introduced by the water transfer activity itself to the water being 
transferred.

when insufficient information exists to make a reasonable judgment 
whether the discharge complies with them.
    (i) To a new source or a new discharger, if the discharge from its 
construction or operation will cause or contribute to the violation of 
water quality standards. The owner or operator of a new source or new 
discharger proposing to discharge into a water segment which does not 
meet applicable water quality standards or is not expected to meet those 
standards even after the application of the effluent limitations 
required by sections 301(b)(1)(A) and 301(b)(1)(B) of CWA, and for which 
the State or interstate agency has performed a pollutants load 
allocation for the pollutant to be discharged, must demonstrate, before 
the

[[Page 179]]

close of the public comment period, that:
    (1) There are sufficient remaining pollutant load allocations to 
allow for the discharge; and
    (2) The existing dischargers into that segment are subject to 
compliance schedules designed to bring the segment into compliance with 
applicable water quality standards. The Director may waive the 
submission of information by the new source or new discharger required 
by paragraph (i) of this section if the Director determines that the 
Director already has adequate information to evaluate the request. An 
explanation of the development of limitations to meet the criteria of 
this paragraph (i)(2) is to be included in the fact sheet to the permit 
under Sec. 124.56(b)(1) of this chapter.

Sec. 122.5  Effect of a permit.

    (a) Applicable to State programs, see Sec. 123.25. (1) Except for 
any toxic effluent standards and prohibitions imposed under section 307 
of the CWA and ``standards for sewage sludge use or disposal'' under 
405(d) of the CWA, compliance with a permit during its term constitutes 
compliance, for purposes of enforcement, with sections 301, 302, 306, 
307, 318, 403, and 405 (a)-(b) of CWA. However, a permit may be 
modified, revoked and reissued, or terminated during its term for cause 
as set forth in Sec. Sec. 122.62 and 122.64.
    (2) Compliance with a permit condition which implements a particular 
``standard for sewage sludge use or disposal'' shall be an affirmative 
defense in any enforcement action brought for a violation of that 
``standard for sewage sludge use or disposal'' pursuant to sections 
405(e) and 309 of the CWA.
    (b) Applicable to State programs, See Sec. 123.25. The issuance of 
a permit does not convey any property rights of any sort, or any 
exclusive privilege.
    (c) The issuance of a permit does not authorize any injury to 
persons or property or invasion of other private rights, or any 
infringement of State or local law or regulations.

[48 FR 14153, Apr. 1, 1983, as amended at 54 FR 18782, May 2, 1989]



Sec. 122.6  Continuation of expiring permits.

    (a) EPA permits. When EPA is the permit-issuing authority, the 
conditions of an expired permit continue in force under 5 U.S.C. 558(c) 
until the effective date of a new permit (see Sec. 124.15) if:
    (1) The permittee has submitted a timely application under Sec. 
122.21 which is a complete (under Sec. 122.21(e)) application for a new 
permit; and
    (2) The Regional Administrator, through no fault of the permittee 
does not issue a new permit with an effective date under Sec. 124.15 on 
or before the expiration date of the previous permit (for example, when 
issuance is impracticable due to time or resource constraints).
    (b) Effect. Permits continued under this section remain fully 
effective and enforceable.
    (c) Enforcement. When the permittee is not in compliance with the 
conditions of the expiring or expired permit the Regional Administrator 
may choose to do any or all of the following:
    (1) Initiate enforcement action based upon the permit which has been 
continued;
    (2) Issue a notice of intent to deny the new permit under Sec. 
124.6. If the permit is denied, the owner or operator would then be 
required to cease the activities authorized by the continued permit or 
be subject to enforcement action for operating without a permit;
    (3) Issue a new permit under part 124 with appropriate conditions; 
or
    (4) Take other actions authorized by these regulations.
    (d) State continuation. (1) An EPA-issued permit does not continue 
in force beyond its expiration date under Federal law if at that time a 
State is the permitting authority. States authorized to administer the 
NPDES program may continue either EPA or State-issued permits until the 
effective date of the new permits, if State law allows. Otherwise, the 
facility or activity is operating without a permit from the time of 
expiration of the old permit to the effective date of the State-issued 
new permit.

Sec. 122.7  Confidentiality of information.

    (a) In accordance with 40 CFR part 2, any information submitted to 
EPA pursuant to these regulations may be claimed as confidential by the 
submitter. Any such claim must be asserted at the time of submission in 
the manner prescribed on the application form or instructions or, in the 
case of other submissions, by stamping the words ``confidential business 
information'' on each page containing such information. If no claim is 
made at the time of submission, EPA may make the information available 
to the public without further notice. If a claim is asserted, the 
information will be treated in accordance with the procedures in 40 CFR 
part 2 (Public Information).
    (b) Applicable to State programs, see Sec. 123.25. Claims of 
confidentiality for the following information will be denied:
    (1) The name and address of any permit applicant or permittee;
    (2) Permit applications, permits, and effluent data.
    (c) Applicable to State programs, see Sec. 123.25. Information 
required by NPDES application forms provided by the Director under Sec. 
122.21 may not be claimed confidential. This includes information 
submitted on the forms themselves and any attachments used to supply 
information required by the forms.



   Subpart B_Permit Application and Special NPDES Program Requirements



Sec. 122.21  Application for a permit (applicable to State programs,
see Sec. 123.25).

    (a) Duty to apply. (1) Any person who discharges or proposes to 
discharge pollutants or who owns or operates a ``sludge-only facility'' 
whose sewage sludge use or disposal practice is regulated by part 503 of 
this chapter, and who does not have an effective permit, except persons 
covered by general permits under Sec. 122.28, excluded under Sec. 
122.3, or a user of a privately owned treatment works unless the 
Director requires otherwise under Sec. 122.44(m), must submit a 
complete application to the Director in accordance with this section and 
part 124 of this chapter. The requirements for concentrated animal 
feeding operations are described in Sec. 122.23(d).
    (2) Application Forms: (i) All applicants for EPA-issued permits 
must submit applications on EPA permit application forms. More than one 
application form may be required from a facility depending on the number 
and types of discharges or outfalls found there. Application forms may 
be obtained by contacting the EPA water resource center at (202) 260-
7786 or Water Resource Center, U.S. EPA, Mail Code 4100, 1200 
Pennsylvania Ave., NW., Washington, DC 20460 or at the EPA Internet site 
www.epa.gov/owm/npdes.htm. Applications for EPA-issued permits must be 
submitted as follows:
    (A) All applicants, other than POTWs and TWTDS, must submit Form 1.
    (B) Applicants for new and existing POTWs must submit the 
information contained in paragraph (j) of this section using Form 2A or 
other form provided by the director.
    (C) Applicants for concentrated animal feeding operations or aquatic 
animal production facilities must submit Form 2B.
    (D) Applicants for existing industrial facilities (including 
manufacturing facilities, commercial facilities, mining activities, and 
silvicultural activities), must submit Form 2C.
    (E) Applicants for new industrial facilities that discharge process 
wastewater must submit Form 2D.
    (F) Applicants for new and existing industrial facilities that 
discharge only nonprocess wastewater must submit Form 2E.
    (G) Applicants for new and existing facilities whose discharge is 
composed entirely of storm water associated with industrial activity 
must submit Form 2F, unless exempted by Sec. 122.26(c)(1)(ii). If the 
discharge is composed of storm water and non-storm water, the applicant 
must also submit, Forms 2C, 2D, and/or 2E, as appropriate (in addition 
to Form 2F).
    (H) Applicants for new and existing TWTDS, subject to paragraph 
(c)(2)(i) of this section must submit the application information 
required by paragraph (q) of this section, using Form 2S or other form 
provided by the director.

[[Page 181]]

    (ii) The application information required by paragraph (a)(2)(i) of 
this section may be electronically submitted if such method of submittal 
is approved by EPA or the Director.
    (iii) Applicants can obtain copies of these forms by contacting the 
Water Management Divisions (or equivalent division which contains the 
NPDES permitting function) of the EPA Regional Offices. The Regional 
Offices' addresses can be found at Sec. 1.7 of this chapter.
    (iv) Applicants for State-issued permits must use State forms which 
must require at a minimum the information listed in the appropriate 
paragraphs of this section.
    (b) Who applies? When a facility or activity is owned by one person 
but is operated by another person, it is the operator's duty to obtain a 
permit.
    (c) Time to apply. (1) Any person proposing a new discharge, shall 
submit an application at least 180 days before the date on which the 
discharge is to commence, unless permission for a later date has been 
granted by the Director. Facilities proposing a new discharge of storm 
water associated with industrial activity shall submit an application 
180 days before that facility commences industrial activity which may 
result in a discharge of storm water associated with that industrial 
activity. Facilities described under Sec. 122.26(b)(14)(x) or 
(b)(15)(i) shall submit applications at least 90 days before the date on 
which construction is to commence. Different submittal dates may be 
required under the terms of applicable general permits. Persons 
proposing a new discharge are encouraged to submit their applications 
well in advance of the 90 or 180 day requirements to avoid delay. See 
also paragraph (k) of this section and Sec. 122.26(c)(1)(i)(G) and 
(c)(1)(ii).
    (2) Permits under section 405(f) of CWA. All TWTDS whose sewage 
sludge use or disposal practices are regulated by part 503 of this 
chapter must submit permit applications according to the applicable 
schedule in paragraphs (c)(2)(i) or (ii) of this section.
    (i) A TWTDS with a currently effective NPDES permit must submit a 
permit application at the time of its next NPDES permit renewal 
application. Such information must be submitted in accordance with 
paragraph (d) of this section.
    (ii) Any other TWTDS not addressed under paragraph (c)(2)(i) of this 
section must submit the information listed in paragraphs (c)(2)(ii)(A) 
through (E) of this section to the Director within 1 year after 
publication of a standard applicable to its sewage sludge use or 
disposal practice(s), using Form 2S or another form provided by the 
Director. The Director will determine when such TWTDS must submit a full 
permit application.
    (A) The TWTDS's name, mailing address, location, and status as 
federal, State, private, public or other entity;
    (B) The applicant's name, address, telephone number, and ownership 
status;
    (C) A description of the sewage sludge use or disposal practices. 
Unless the sewage sludge meets the requirements of paragraph (q)(8)(iv) 
of this section, the description must include the name and address of 
any facility where sewage sludge is sent for treatment or disposal, and 
the location of any land application sites;
    (D) Annual amount of sewage sludge generated, treated, used or 
disposed (estimated dry weight basis); and
    (E) The most recent data the TWTDS may have on the quality of the 
sewage sludge.
    (iii) Notwithstanding paragraphs (c)(2)(i) or (ii) of this section, 
the Director may require permit applications from any TWTDS at any time 
if the Director determines that a permit is necessary to protect public 
health and the environment from any potential adverse effects that may 
occur from toxic pollutants in sewage sludge.
    (iv) Any TWTDS that commences operations after promulgation of an 
applicable ``standard for sewage sludge use or disposal'' must submit an 
application to the Director at least 180 days prior to the date proposed 
for commencing operations.
    (d) Duty to reapply. (1) Any POTW with a currently effective permit 
shall submit a new application at least 180 days before the expiration 
date of the existing permit, unless permission for a later date has been 
granted by the Director. (The Director shall not grant

[[Page 182]]

permission for applications to be submitted later than the expiration 
date of the existing permit.)
    (2) All other permittees with currently effective permits shall 
submit a new application 180 days before the existing permit expires, 
except that:
    (i) The Regional Administrator may grant permission to submit an 
application later than the deadline for submission otherwise applicable, 
but no later than the permit expiration date; and
    (3) [Reserved]
    (e) Completeness. (1) The Director shall not issue a permit before 
receiving a complete application for a permit except for NPDES general 
permits. An application for a permit is complete when the Director 
receives an application form and any supplemental information which are 
completed to his or her satisfaction. The completeness of any 
application for a permit shall be judged independently of the status of 
any other permit application or permit for the same facility or 
activity. For EPA administered NPDES programs, an application which is 
reviewed under Sec. 124.3 of this chapter is complete when the Director 
receives either a complete application or the information listed in a 
notice of deficiency.
    (2) A permit application shall not be considered complete if a 
permitting authority has waived application requirements under 
paragraphs (j) or (q) of this section and EPA has disapproved the waiver 
application. If a waiver request has been submitted to EPA more than 210 
days prior to permit expiration and EPA has not disapproved the waiver 
application 181 days prior to permit expiration, the permit application 
lacking the information subject to the waiver application shall be 
considered complete.
    (3) Except as specified in 122.21(e)(3)(ii), a permit application 
shall not be considered complete unless all required quantitative data 
are collected in accordance with sufficiently sensitive analytical 
methods approved under 40 CFR part 136 or required under 40 CFR chapter 
I, subchapter N or O.
    (i) For the purposes of this requirement, a method approved under 40 
CFR part 136 or required under 40 CFR chapter I, subchapter N or O is 
``sufficiently sensitive'' when:
    (A) The method minimum level (ML) is at or below the level of the 
applicable water quality criterion for the measured pollutant or 
pollutant parameter; or
    (B) The method ML is above the applicable water quality criterion, 
but the amount of the pollutant or pollutant parameter in a facility's 
discharge is high enough that the method detects and quantifies the 
level of the pollutant or pollutant parameter in the discharge; or
    (C) The method has the lowest ML of the analytical methods approved 
under 40 CFR part 136 or required under 40 CFR chapter I, subchapter N 
or O for the measured pollutant or pollutant parameter.

    Note to paragraph (e)(3)(i):
    Consistent with 40 CFR part 136, applicants have the option of 
providing matrix or sample specific minimum levels rather than the 
published levels. Further, where an applicant can demonstrate that, 
despite a good faith effort to use a method that would otherwise meet 
the definition of ``sufficiently sensitive'', the analytical results are 
not consistent with the QA/QC specifications for that method, then the 
Director may determine that the method is not performing adequately and 
the applicant should select a different method from the remaining EPA-
approved methods that is sufficiently sensitive consistent with 40 CFR 
122.21(e)(3)(i). Where no other EPA-approved methods exist, the 
applicant should select a method consistent with 40 CFR 
122.21(e)(3)(ii).

    (ii) When there is no analytical method that has been approved under 
40 CFR part 136, required under 40 CFR chapter I, subchapter N or O, and 
is not otherwise required by the Director, the applicant may use any 
suitable method but shall provide a description of the method. When 
selecting a suitable method, other factors such as a method's precision, 
accuracy, or resolution, may be considered when assessing the 
performance of the method.
    (f) Information requirements. All applicants for NPDES permits, 
other than POTWs and other TWTDS, must provide the following information 
to the Director, using the application form provided by the Director. 
Additional information required of applicants is set forth in paragraphs 
(g) through (k) of this section.

[[Page 183]]

    (1) The activities conducted by the applicant which require it to 
obtain an NPDES permit.
    (2) Name, mailing address, and location of the facility for which 
the application is submitted.
    (3) Up to four SIC codes which best reflect the principal products 
or services provided by the facility.
    (4) The operator's name, address, telephone number, ownership 
status, and status as Federal, State, private, public, or other entity.
    (5) Whether the facility is located on Indian lands.
    (6) A listing of all permits or construction approvals received or 
applied for under any of the following programs:
    (i) Hazardous Waste Management program under RCRA.
    (ii) UIC program under SDWA.
    (iii) NPDES program under CWA.
    (iv) Prevention of Significant Deterioration (PSD) program under the 
Clean Air Act.
    (v) Nonattainment program under the Clean Air Act.
    (vi) National Emission Standards for Hazardous Pollutants (NESHAPS) 
preconstruction approval under the Clean Air Act.
    (vii) Ocean dumping permits under the Marine Protection Research and 
Sanctuaries Act.
    (viii) Dredge or fill permits under section 404 of CWA.
    (ix) Other relevant environmental permits, including State permits.
    (7) A topographic map (or other map if a topographic map is 
unavailable) extending one mile beyond the property boundaries of the 
source, depicting the facility and each of its intake and discharge 
structures; each of its hazardous waste treatment, storage, or disposal 
facilities; each well where fluids from the facility are injected 
underground; and those wells, springs, other surface water bodies, and 
drinking water wells listed in public records or otherwise known to the 
applicant in the map area.
    (8) A brief description of the nature of the business.
    (g) Application requirements for existing manufacturing, commercial, 
mining, and silvicultural dischargers. Existing manufacturing, 
commercial mining, and silvicultural dischargers applying for NPDES 
permits, except for those facilities subject to the requirements of 
Sec. 122.21(h), shall provide the following information to the 
Director, using application forms provided by the Director.
    (1) Outfall location. The latitude and longitude to the nearest 15 
seconds and the name of the receiving water.
    (2) Line drawing. A line drawing of the water flow through the 
facility with a water balance, showing operations contributing 
wastewater to the effluent and treatment units. Similar processes, 
operations, or production areas may be indicated as a single unit, 
labeled to correspond to the more detailed identification under 
paragraph (g)(3) of this section. The water balance must show 
approximate average flows at intake and discharge points and between 
units, including treatment units. If a water balance cannot be 
determined (for example, for certain mining activities), the applicant 
may provide instead a pictorial description of the nature and amount of 
any sources of water and any collection and treatment measures.
    (3) Average flows and treatment. A narrative identification of each 
type of process, operation, or production area which contributes 
wastewater to the effluent for each outfall, including process 
wastewater, cooling water, and stormwater runoff; the average flow which 
each process contributes; and a description of the treatment the 
wastewater receives, including the ultimate disposal of any solid or 
fluid wastes other than by discharge. Processes, operations, or 
production areas may be described in general terms (for example, ``dye-
making reactor'', ``distillation tower''). For a privately owned 
treatment works, this information shall include the identity of each 
user of the treatment works. The average flow of point sources composed 
of storm water may be estimated. The basis for the rainfall event and 
the method of estimation must be indicated.
    (4) Intermittent flows. If any of the discharges described in 
paragraph (g)(3) of this section are intermittent or seasonal, a 
description of the frequency,

[[Page 184]]

duration and flow rate of each discharge occurrence (except for 
stormwater runoff, spillage or leaks).
    (5) Maximum production. If an effluent guideline promulgated under 
section 304 of CWA applies to the applicant and is expressed in terms of 
production (or other measure of operation), a reasonable measure of the 
applicant's actual production reported in the units used in the 
applicable effluent guideline. The reported measure must reflect the 
actual production of the facility as required by Sec. 122.45(b)(2).
    (6) Improvements. If the applicant is subject to any present 
requirements or compliance schedules for construction, upgrading or 
operation of waste treatment equipment, an identification of the 
abatement requirement, a description of the abatement project, and a 
listing of the required and projected final compliance dates.
    (7) Effluent characteristics. (i) Information on the discharge of 
pollutants specified in this paragraph (g)(7) (except information on 
storm water discharges which is to be provided as specified in Sec. 
122.26). When ``quantitative data'' for a pollutant are required, the 
applicant must collect a sample of effluent and analyze it for the 
pollutant in accordance with analytical methods approved under Part 136 
of this chapter unless use of another method is required for the 
pollutant under 40 CFR subchapters N or O. When no analytical method is 
approved under Part 136 or required under subchapters N or O, the 
applicant may use any suitable method but must provide a description of 
the method. When an applicant has two or more outfalls with 
substantially identical effluents, the Director may allow the applicant 
to test only one outfall and report that quantitative data as applying 
to the substantially identical outfall. The requirements in paragraphs 
(g)(7)(vi) and (vii) of this section state that an applicant must 
provide quantitative data for certain pollutants known or believed to be 
present do not apply to pollutants present in a discharge solely as the 
result of their presence in intake water; however, an applicant must 
report such pollutants as present. When paragraph (g)(7) of this section 
requires analysis of pH, temperature, cyanide, total phenols, residual 
chlorine, oil and grease, fecal coliform (including E. coli), and 
Enterococci (previously known as fecal streptococcus at Sec. 122.26 
(d)(2)(iii)(A)(3)), or volatile organics, grab samples must be collected 
for those pollutants. For all other pollutants, a 24-hour composite 
sample, using a minimum of four (4) grab samples, must be used unless 
specified otherwise at 40 CFR Part 136. However, a minimum of one grab 
sample may be taken for effluents from holding ponds or other 
impoundments with a retention period greater than 24 hours. In addition, 
for discharges other than storm water discharges, the Director may waive 
composite sampling for any outfall for which the applicant demonstrates 
that the use of an automatic sampler is infeasible and that the minimum 
of four (4) grab samples will be a representative sample of the effluent 
being discharged. Results of analyses of individual grab samples for any 
parameter may be averaged to obtain the daily average. Grab samples that 
are not required to be analyzed immediately (see Table II at 40 CFR 
136.3 (e)) may be composited in the laboratory, provided that container, 
preservation, and holding time requirements are met (see Table II at 40 
CFR 136.3 (e)) and that sample integrity is not compromised by 
compositing.
    (ii) Storm water discharges. For storm water discharges, all samples 
shall be collected from the discharge resulting from a storm event that 
is greater than 0.1 inch and at least 72 hours from the previously 
measurable (greater than 0.1 inch rainfall) storm event. Where feasible, 
the variance in the duration of the event and the total rainfall of the 
event should not exceed 50 percent from the average or median rainfall 
event in that area. For all applicants, a flow-weighted composite shall 
be taken for either the entire discharge or for the first three hours of 
the discharge. The flow-weighted composite sample for a storm water 
discharge may be taken with a continuous sampler or as a combination of 
a minimum of three sample aliquots taken in each hour of discharge for 
the entire discharge or for the first three hours of the discharge, with 
each aliquot being separated by a minimum period of fifteen

[[Page 185]]

minutes (applicants submitting permit applications for storm water 
discharges under Sec. 122.26(d) may collect flow-weighted composite 
samples using different protocols with respect to the time duration 
between the collection of sample aliquots, subject to the approval of 
the Director). However, a minimum of one grab sample may be taken for 
storm water discharges from holding ponds or other impoundments with a 
retention period greater than 24 hours. For a flow-weighted composite 
sample, only one analysis of the composite of aliquots is required. For 
storm water discharge samples taken from discharges associated with 
industrial activities, quantitative data must be reported for the grab 
sample taken during the first thirty minutes (or as soon thereafter as 
practicable) of the discharge for all pollutants specified in Sec. 
122.26(c)(1). For all storm water permit applicants taking flow-weighted 
composites, quantitative data must be reported for all pollutants 
specified in Sec. 122.26 except pH, temperature, cyanide, total 
phenols, residual chlorine, oil and grease, fecal coliform, and fecal 
streptococcus. The Director may allow or establish appropriate site-
specific sampling procedures or requirements, including sampling 
locations, the season in which the sampling takes place, the minimum 
duration between the previous measurable storm event and the storm event 
sampled, the minimum or maximum level of precipitation required for an 
appropriate storm event, the form of precipitation sampled (snow melt or 
rain fall), protocols for collecting samples under part 136 of this 
chapter, and additional time for submitting data on a case-by-case 
basis. An applicant is expected to ``know or have reason to believe'' 
that a pollutant is present in an effluent based on an evaluation of the 
expected use, production, or storage of the pollutant, or on any 
previous analyses for the pollutant. (For example, any pesticide 
manufactured by a facility may be expected to be present in contaminated 
storm water runoff from the facility.)
    (iii) Reporting requirements. Every applicant must report 
quantitative data for every outfall for the following pollutants:

Biochemical Oxygen Demand (BOD5)
Chemical Oxygen Demand
Total Organic Carbon
Total Suspended Solids
Ammonia (as N)
Temperature (both winter and summer)
pH

    (iv) The Director may waive the reporting requirements for 
individual point sources or for a particular industry category for one 
or more of the pollutants listed in paragraph (g)(7)(iii) of this 
section if the applicant has demonstrated that such a waiver is 
appropriate because information adequate to support issuance of a permit 
can be obtained with less stringent requirements.
    (v) Each applicant with processes in one or more primary industry 
category (see appendix A of this part) contributing to a discharge must 
report quantitative data for the following pollutants in each outfall 
containing process wastewater:
    (A) The organic toxic pollutants in the fractions designated in 
table I of appendix D of this part for the applicant's industrial 
category or categories unless the applicant qualifies as a small 
business under paragraph (g)(8) of this section. Table II of appendix D 
of this part lists the organic toxic pollutants in each fraction. The 
fractions result from the sample preparation required by the analytical 
procedure which uses gas chromatography/mass spectrometry. A 
determination that an applicant falls within a particular industrial 
category for the purposes of selecting fractions for testing is not 
conclusive as to the applicant's inclusion in that category for any 
other purposes. See Notes 2, 3, and 4 of this section.
    (B) The pollutants listed in table III of appendix D of this part 
(the toxic metals, cyanide, and total phenols).
    (vi)(A) Each applicant must indicate whether it knows or has reason 
to believe that any of the pollutants in table IV of appendix D of this 
part (certain conventional and nonconventional pollutants) is discharged 
from each outfall. If an applicable effluent limitations guideline 
either directly limits the pollutant or, by its express terms, 
indirectly limits the pollutant through limitations on an indicator, the 
applicant must report quantitative data.

[[Page 186]]

For every pollutant discharged which is not so limited in an effluent 
limitations guideline, the applicant must either report quantitative 
data or briefly describe the reasons the pollutant is expected to be 
discharged.
    (B) Each applicant must indicate whether it knows or has reason to 
believe that any of the pollutants listed in table II or table III of 
appendix D of this part (the toxic pollutants and total phenols) for 
which quantitative data are not otherwise required under paragraph 
(g)(7)(v) of this section are discharged from each outfall. For every 
pollutant expected to be discharged in concentrations of 10 ppb or 
greater the applicant must report quantitative data. For acrolein, 
acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4, 6 dinitrophenol, where 
any of these four pollutants are expected to be discharged in 
concentrations of 100 ppb or greater the applicant must report 
quantitative data. For every pollutant expected to be discharged in 
concentrations less than 10 ppb, or in the case of acrolein, 
acrylonitrile, 2,4 dinitrophenol, and 2-methyl-4, 6 dinitrophenol, in 
concentrations less than 100 ppb, the applicant must either submit 
quantitative data or briefly describe the reasons the pollutant is 
expected to be discharged. An applicant qualifying as a small business 
under paragraph (g)(8) of this section is not required to analyze for 
pollutants listed in table II of appendix D of this part (the organic 
toxic pollutants).
    (vii) Each applicant must indicate whether it knows or has reason to 
believe that any of the pollutants in table V of appendix D of this part 
(certain hazardous substances and asbestos) are discharged from each 
outfall. For every pollutant expected to be discharged, the applicant 
must briefly describe the reasons the pollutant is expected to be 
discharged, and report any quantitative data it has for any pollutant.
    (viii) Each applicant must report qualitative data, generated using 
a screening procedure not calibrated with analytical standards, for

support issuance of a permit can be obtained through less stringent 
requirements.
    (iii) If the applicant is a new discharger, he must complete and 
submit Item IV of Form 2e (see Sec. 122.21(h)(4)) by providing 
quantitative data in accordance with that section no later than two 
years after commencement of discharge. However, the applicant need not 
complete those portions of Item IV requiring tests which he has already 
performed and reported under the discharge monitoring requirements of 
his NPDES permit.
    (iv) The requirements of parts i and iii of this section that an 
applicant

[[Page 188]]

    (vii) All existing data for pollutants specified in paragraphs 
(j)(4)(ii) through (v) of this section that is collected within four and 
one-half years of the application must be included in the pollutant data 
summary submitted by the applicant. If, however, the applicant samples 
for a specific pollutant on a monthly or more frequent basis, it is only 
necessary, for such pollutant, to

[[Page 192]]

summarize all data collected within one year of the application.
    (viii) Applicants must collect samples of effluent and analyze such 
samples for pollutants in accordance with analytical methods approved 
under 40 CFR Part 136 unless an alternative is specified in the existing 
NPDES permit. When analysis of pH, temperature, cyanide, total phenols, 
residual chlorine, oil and grease, fecal coliform (including E. coli),

the application on any of the applicant's discharges or on any receiving 
water near the discharge.
    (ii) As provided in paragraphs (j)(5)(iii)-(ix) of this section, the 
following applicants must submit to the Director the results of valid 
whole effluent toxicity tests for acute or chronic toxicity for samples 
taken from each outfall through which effluent is discharged to surface 
waters, except for combined sewer overflows:
    (A) All POTWs with design flow rates greater than or equal to one 
million gallons per day;
    (B) All POTWs with approved pretreatment programs or POTWs required 
to develop a pretreatment program;
    (C) Other POTWs, as required by the Director, based on consideration 
of the following factors:
    (1) The variability of the pollutants or pollutant parameters in the 
POTW effluent (based on chemical-specific information, the type of 
treatment plant, and types of industrial contributors);
    (2) The ratio of effluent flow to receiving stream flow;
    (3) Existing controls on point or non-point sources, including total 
maximum daily load calculations for the receiving stream segment and the 
relative contribution of the POTW;
    (4) Receiving stream characteristics, including possible or known 
water quality impairment, and whether the POTW discharges to a coastal 
water, one of the Great Lakes, or a water designated as an outstanding 
natural resource water; or
    (5) Other considerations (including, but not limited to, the history 
of toxic impacts and compliance problems at the POTW) that the Director 
determines could cause or contribute to adverse water quality impacts.
    (iii) Where the POTW has two or more outfalls with substantially 
identical effluent discharging to the same receiving stream segment, the 
Director may allow applicants to submit whole effluent toxicity data for 
only one outfall on a case-by-case basis. The Director may also allow 
applicants to composite samples from one or more outfalls that discharge 
into the same mixing zone.
    (iv) Each applicant required to perform whole effluent toxicity 
testing pursuant to paragraph (j)(5)(ii) of this section must provide:
    (A) Results of a minimum of four quarterly tests for a year, from 
the year preceding the permit application; or
    (B) Results from four tests performed at least annually in the four 
and one half year period prior to the application, provided the results 
show no appreciable toxicity using a safety factor determined by the 
permitting authority.
    (v) Applicants must conduct tests with multiple species (no less 
than two species; e.g., fish, invertebrate, plant),

[[Page 193]]

and test for acute or chronic toxicity, depending on the range of 
receiving water dilution. EPA recommends that applicants conduct acute 
or chronic testing based on the following dilutions:
    (A) Acute toxicity testing if the dilution of the effluent is 
greater than 1000:1 at the edge of the mixing zone;
    (B) Acute or chronic toxicity testing if the dilution of the 
effluent is between 100:1 and 1000:1 at the edge of the mixing zone. 
Acute testing may be more appropriate at the higher end of this range 
(1000:1), and chronic testing may be more appropriate at the lower end 
of this range (100:1); and
    (C) Chronic testing if the dilution of the effluent is less than 
100:1 at the edge of the mixing zone.
    (vi) Each applicant required to perform whole effluent toxicity 
testing pursuant to paragraph (j)(5)(ii) of this section must provide 
the number of chronic or acute whole effluent toxicity tests that have 
been conducted since the last permit reissuance.
    (vii) Applicants must provide the results using the form provided by 
the Director, or test summaries if available and comprehensive, for each 
whole effluent toxicity test conducted pursuant to paragraph (j)(5)(ii) 
of this section for which such information has not been reported 
previously to the Director.
    (viii) Whole effluent toxicity testing conducted pursuant to 
paragraph (j)(5)(ii) of this section must be conducted using methods 
approved under 40 CFR part 136. West coast facilities in Washington, 
Oregon, California, Alaska, Hawaii, and the Pacific Territories are 
exempted from 40 CFR part 136 chronic methods and must use alternative 
guidance as directed by the permitting authority.
    (ix) For whole effluent toxicity data submitted to the Director 
within four and one-half years prior to the date of the application, 
applicants must provide the dates on which the data were submitted and a 
summary of the results.
    (x) Each POTW required to perform whole effluent toxicity testing 
pursuant to paragraph (j)(5)(ii) of this section must provide any 
information on the cause of toxicity and written details of any toxicity

Notwithstanding the time requirements in paragraphs (m) and (n) of this 
section, the Director may notify a permit applicant before a draft 
permit is issued under Sec. 124.6 that the draft permit will likely 
contain limitations which are eligible for variances. In the notice the 
Director may require the applicant as a condition of consideration of 
any potential variance request to submit a request explaining how the 
requirements of part 125 applicable to the variance have been met and 
may require its submission within a specified reasonable time after 
receipt of the notice. The notice may be sent before the permit 
application has been submitted. The draft or final permit may contain 
the alternative limitations which may become effective upon final grant 
of the variance.
    (2) A discharger who cannot file a timely complete request required 
under paragraph (m)(2)(i)(B) or (m)(2)(ii) of this section may request 
an extension. The extension may be granted or denied at the discretion 
of the Director. Extensions shall be no more than 6 months in duration.
    (p) Recordkeeping. Except for information required by paragraph 
(d)(3)(ii) of this section, which shall be retained for a period of at 
least five years from the date the application is signed (or longer as 
required by 40 CFR part 503), applicants shall keep records of all data 
used to complete permit applications and any supplemental information 
submitted under this section for a period of at least 3 years from the 
date the application is signed.
    (q) Sewage sludge management. All TWTDS subject to paragraph 
(c)(2)(i) of this section must provide the information in this paragraph 
to the Director, using Form 2S or another application form approved by 
the Director. New applicants must submit all information available at 
the time of permit application. The information may be provided by 
referencing information previously submitted to the Director. The 
Director may waive any requirement of this paragraph if he or she has 
access to substantially identical information. The Director may also 
waive any requirement of this paragraph that is not of material concern 
for a specific permit, if approved by the Regional Administrator. The 
waiver request to the Regional Administrator must include the State's 
justification for the waiver. A Regional Administrator's disapproval of 
a State's proposed waiver does not constitute final Agency action, but 
does provide notice to the State and permit applicant(s) that EPA may 
object to any State-issued permit issued in the absence of the required 
information.

structure at its facility. The applicant must identify any intake 
structure for which a BTA determination for Impingement Mortality under 
40 CFR 125.94 (c)(11) or (12) is requested. In addition, the owner or 
operator that chooses to comply via 40 CFR 125.94 (c)(5) or (6) must 
also submit an impingement technology performance optimization study as 
described below:
    (i) If the applicant chooses to comply with 40 CFR 125.94(c)(5), 
subject to the flexibility for timing provided in 40 CFR 125.95(a)(2), 
the impingement technology performance optimization study must include 
two years of biological data collection measuring the reduction in 
impingement mortality achieved by the modified traveling screens as 
defined at 40 CFR 125.92(s) and demonstrating that the operation has 
been optimized to minimize impingement mortality. A complete description 
of the modified traveling screens and associated equipment must be 
included, including, for example, type of mesh, mesh slot size, pressure 
sprays and fish return mechanisms. A description of any biological data 
collection and data collection approach used in measuring impingement 
mortality must be included:
    (A) Collecting data no less frequently than monthly. The Director 
may establish more frequent data collection;
    (B) Biological data collection representative of the impingement and 
the impingement mortality at the intakes subject to this provision;
    (C) A taxonomic identification to the lowest taxon possible of all 
organisms collected;
    (D) The method in which naturally moribund organisms are identified 
and taken into account;
    (E) The method in which mortality due to holding times is taken into 
account;
    (F) If the facility entraps fish or shellfish, a count of 
entrapment, as defined at 40 CFR 125.92(j), as impingement mortality; 
and
    (G) The percent impingement mortality reflecting optimized operation 
of the modified traveling screen and all supporting calculations.
    (ii) If the applicant chooses to comply with 40 CFR 125.94(c)(6), 
the impingement technology performance optimization study must include 
biological data measuring the reduction in impingement mortality 
achieved by operation of the system of technologies, operational 
measures and best management practices, and demonstrating

[[Page 208]]

that operation of the system has been optimized to minimize impingement 
mortality. This system of technologies, operational measures and best 
management practices may include flow reductions, seasonal operation, 
unit closure, credit for intake location, and behavioral deterrent 
systems. The applicant must document how each system element contributes 
to the system's performance. The applicant must include a minimum of two 
years of biological data measuring the reduction in impingement 
mortality achieved by the system. The applicant must also include a 
description of any sampling or data collection approach used in 
measuring the rate of impingement, impingement mortality, or flow 
reductions.
    (A) Rate of Impingement. If the demonstration relies in part on a 
credit for reductions in the rate of impingement in the system, the 
applicant must provide an estimate of those reductions to be used as 
credit towards reducing impingement mortality, and any relevant 
supporting documentation, including previously collected biological 
data, performance reviews, and previously conducted performance studies 
not already submitted to the Director. The submission of studies more 
than 10 years old must include an explanation of why the data are still 
relevant and representative of conditions at the facility and explain 
how the data should be interpreted using the definitions of impingement 
and entrapment at 40 CFR 125.92(n) and (j), respectively. The estimated 
reductions in rate of impingement must be based on a comparison of the 
system to a once-through cooling system with a traveling screen whose 
point of withdrawal from the surface water source is located at the 
shoreline of the source waterbody. For impoundments that are waters of 
the United States in whole or in part, the facility's rate of 
impingement must be measured at a location within the cooling water 
intake system that the Director deems appropriate. In addition, the 
applicant must include two years of biological data collection 
demonstrating the rate of impingement resulting from the system. For 
this demonstration, the applicant must collect data no less frequently 
than monthly. The Director may establish more frequent data collection.
    (B) Impingement Mortality. If the demonstration relies in part on a 
credit for reductions in impingement mortality already obtained at the 
facility, the applicant must include two years of biological data 
collection demonstrating the level of impingement mortality the system 
is capable of achieving. The applicant must submit any relevant 
supporting documentation, including previously collected biological 
data, performance reviews, and previously conducted performance studies 
not already submitted to the Director. The applicant must provide a 
description of any sampling or data collection approach used in 
measuring impingement mortality. In addition, for this demonstration the 
applicant must:
    (1) Collect data no less frequently than monthly. The Director may 
establish more frequent data collection;
    (2) Conduct biological data collection that is representative of the 
impingement and the impingement mortality at an intake subject to this 
provision. In addition, the applicant must describe how the location of 
the cooling water intake structure in the waterbody and the water column 
are accounted for in the points of data collection;
    (3) Include a taxonomic identification to the lowest taxon possible 
of all organisms to be collected;
    (4) Describe the method in which naturally moribund organisms are 
identified and taken into account;
    (5) Describe the method in which mortality due to holding times is 
taken into account; and
    (6) If the facility entraps fish or shellfish, a count of the 
entrapment, as defined at 40 CFR 125.92(j), as impingement mortality.
    (C) Flow reduction. If the demonstration relies in part on flow 
reduction to reduce impingement, the applicant must include two years of 
intake flows, measured daily, as part of the demonstration, and describe 
the extent to which flow reductions are seasonal or intermittent. The 
applicant must document how the flow reduction results in reduced 
impingement. In addition, the

[[Page 209]]

applicant must describe how the reduction in impingement has reduced 
impingement mortality.
    (D) Total system performance. The applicant must document the 
percent impingement mortality reflecting optimized operation of the 
total system of technologies, operational measures, and best management 
practices and all supporting calculations. The total system performance 
is the combination of the impingement mortality performance reflected in 
paragraphs (r)(6)(ii)(A), (B), and (C) of this section.
    (7) Entrainment Performance Studies. The owner or operator of an 
existing facility must submit any previously conducted studies or 
studies obtained from other facilities addressing technology efficacy, 
through-facility entrainment survival, and other entrainment studies. 
Any such submittals must include a description of each study, together 
with underlying data, and a summary of any conclusions or results. Any 
studies conducted at other locations must include an explanation as to 
why the data from other locations are relevant and representative of 
conditions at your facility. In the case of studies more than 10 years 
old, the applicant must explain why the data are still relevant and 
representative of conditions at the facility and explain how the data 
should be interpreted using the definition of entrainment at 40 CFR 
125.92(h).
    (8) Operational Status. The owner or operator of an existing 
facility must submit a description of the operational status of each 
generating, production, or process unit that uses cooling water, 
including but not limited to:
    (i) For power production or steam generation, descriptions of 
individual unit operating status including age of each unit, capacity 
utilization rate (or equivalent) for the previous 5 years, including any 
extended or unusual outages that significantly affect current data for 
flow, impingement, entrainment, or other factors, including 
identification of any operating unit with a capacity utilization rate of 
less than 8 percent averaged over a 24-month block contiguous period, 
and any major upgrades completed within the last 15 years, including but 
not limited to boiler replacement, condenser replacement, turbine 
replacement, or changes to fuel type;
    (ii) Descriptions of completed, approved, or scheduled uprates and 
Nuclear Regulatory Commission relicensing status of each unit at nuclear 
facilities;
    (iii) For process units at your facility that use cooling water 
other than for power production or steam generation, if you intend to 
use reductions in flow or changes in operations to meet the requirements 
of 40 CFR 125.94(c), descriptions of individual production processes and 
product lines, operating status including age of each line, seasonal 
operation, including any extended or unusual outages that significantly 
affect current data for flow, impingement, entrainment, or other 
factors, any major upgrades completed within the last 15 years, and 
plans or schedules for decommissioning or replacement of process units 
or production processes and product lines;
    (iv) For all manufacturing facilities, descriptions of current and 
future production schedules; and
    (v) Descriptions of plans or schedules for any new units planned 
within the next 5 years.
    (9) Entrainment Characterization Study. The owner or operator of an 
existing facility that withdraws greater than 125 mgd AIF, where the 
withdrawal of cooling water is measured at a location within the cooling 
water intake structure that the Director deems appropriate, must develop 
for submission to the Director an Entrainment Characterization Study 
that includes a minimum of two years of entrainment data collection. The 
Entrainment Characterization Study must include the following 
components:
    (i) Entrainment Data Collection Method. The study should identify 
and document the data collection period and frequency. The study should 
identify and document organisms collected to the lowest taxon possible 
of all life stages of fish and shellfish that are in the vicinity of the 
cooling water intake structure(s) and are susceptible to entrainment, 
including any organisms identified by the Director, and any species 
protected under Federal, State, or Tribal law, including threatened or 
endangered species with a habitat range

[[Page 210]]

that includes waters in the vicinity of the cooling water intake 
structure. Biological data collection must be representative of the 
entrainment at the intakes subject to this provision. The owner or 
operator of the facility must identify and document how the location of 
the cooling water intake structure in the waterbody and the water column 
are accounted for by the data collection locations;
    (ii) Biological Entrainment Characterization. Characterization of 
all life stages of fish, shellfish, and any species protected under 
Federal, State, or Tribal law (including threatened or endangered 
species), including a description of their abundance and their temporal 
and spatial characteristics in the vicinity of the cooling water intake 
structure(s), based on sufficient data to characterize annual, seasonal, 
and diel variations in entrainment, including but not limited to 
variations related to climate and weather differences, spawning, 
feeding, and water column migration. This characterization may include 
historical data that are representative of the current operation of the 
facility and of biological conditions at the site. Identification of all 
life stages of fish and shellfish must include identification of any 
surrogate species used, and identification of data representing both 
motile and non-motile life-stages of organisms;
    (iii) Analysis and Supporting Documentation. Documentation of the 
current entrainment of all life stages of fish, shellfish, and any 
species protected under Federal, State, or Tribal law (including 
threatened or endangered species). The documentation may include 
historical data that are representative of the current operation of the 
facility and of biological conditions at the site. Entrainment data to 
support the facility's calculations must be collected during periods of 
representative operational flows for the cooling water intake structure, 
and the flows associated with the data collection must be documented. 
The method used to determine latent mortality along with data for 
specific organism mortality or survival that is applied to other life-
stages or species must be identified. The owner or operator of the 
facility must identify and document all assumptions and calculations 
used to determine the total entrainment for that facility together with 
all methods and quality assurance/quality control procedures for data 
collection and data analysis. The proposed data collection and data 
analysis methods must be appropriate for a quantitative survey.
    (10) Comprehensive Technical Feasibility and Cost Evaluation Study. 
The owner or operator of an existing facility that withdraws greater 
than 125 mgd AIF must develop for submission to the Director an 
engineering study of the technical feasibility and incremental costs of 
candidate entrainment control technologies. In addition, the study must 
include the following:
    (i) Technical feasibility. An evaluation of the technical 
feasibility of closed-cycle recirculating systems as defined at 40 CFR 
125.92(c), fine mesh screens with a mesh size of 2 millimeters or 
smaller, and water reuse or alternate sources of cooling water. In 
addition, this study must include:
    (A) A description of all technologies and operational measures 
considered (including alternative designs of closed-cycle recirculating 
systems such as natural draft cooling towers, mechanical draft cooling 
towers, hybrid designs, and compact or multi-cell arrangements);
    (B) A discussion of land availability, including an evaluation of 
adjacent land and acres potentially available due to generating unit 
retirements, production unit retirements, other buildings and equipment 
retirements, and potential for repurposing of areas devoted to ponds, 
coal piles, rail yards, transmission yards, and parking lots;
    (C) A discussion of available sources of process water, grey water, 
waste water, reclaimed water, or other waters of appropriate quantity 
and quality for use as some or all of the cooling water needs of the 
facility; and
    (D) Documentation of factors other than cost that may make a 
candidate technology impractical or infeasible for further evaluation.
    (ii) Other entrainment control technologies. An evaluation of 
additional technologies for reducing entrainment may be required by the 
Director.
    (iii) Cost evaluations. The study must include engineering cost 
estimates of

[[Page 211]]

all technologies considered in paragraphs (r)(10)(i) and (ii) of this 
section. Facility costs must also be adjusted to estimate social costs. 
All costs must be presented as the net present value (NPV) and the 
corresponding annual value. Costs must be clearly labeled as compliance 
costs or social costs. The applicant must separately discuss facility 
level compliance costs and social costs, and provide documentation as 
follows:
    (A) Compliance costs are calculated as after-tax, while social costs 
are calculated as pre-tax. Compliance costs include the facility's 
administrative costs, including costs of permit application, while the 
social cost adjustment includes the Director's administrative costs. Any 
outages, downtime, or other impacts to facility net revenue, are 
included in compliance costs, while only that portion of lost net 
revenue that does not accrue to other producers can be included in 
social costs. Social costs must also be discounted using social discount 
rates of 3 percent and 7 percent. Assumptions regarding depreciation 
schedules, tax rates, interest rates, discount rates and related 
assumptions must be identified;
    (B) Costs and explanation of any additional facility modifications 
necessary to support construction and operation of technologies 
considered in paragraphs (r)(10)(i) and (ii) of this section, including 
but not limited to relocation of existing buildings or equipment, 
reinforcement or upgrading of existing equipment, and additional 
construction and operating permits. Assumptions regarding depreciation 
schedules, interest rates, discount rates, useful life of the technology 
considered, and any related assumptions must be identified; and
    (C) Costs and explanation for addressing any non-water quality 
environmental and other impacts identified in paragraph (r)(12) of this 
section. The cost evaluation must include a discussion of all reasonable 
attempts to mitigate each of these impacts.
    (11) Benefits Valuation Study. The owner or operator of an existing 
facility that withdraws greater than 125 mgd AIF must develop for 
submission to the Director an evaluation of the benefits of the 
candidate entrainment reduction technologies and operational measures 
evaluated in paragraph (r)(10) of this section including using the 
Entrainment Characterization Study completed in paragraph (r)(9) of this 
section. Each category of benefits must be described narratively, and 
when possible, benefits should be quantified in physical or biological 
units and monetized using appropriate economic valuation methods. The 
benefits valuation study must include, but is not limited to, the 
following elements:
    (i) Incremental changes in the numbers of individual fish and 
shellfish lost due to impingement mortality and entrainment as defined 
in 40 CFR 125.92, for all life stages of each exposed species;
    (ii) Description of basis for any estimates of changes in the stock 
sizes or harvest levels of commercial and recreational fish or shellfish 
species or forage fish species;
    (iii) Description of basis for any monetized values assigned to 
changes in the stock size or harvest levels of commercial and 
recreational fish or shellfish species, forage fish, and to any other 
ecosystem or non use benefits;
    (iv) A discussion of mitigation efforts completed prior to October 
14, 2014 including how long they have been in effect and how effective 
they have been;
    (v) Discussion, with quantification and monetization, where 
possible, of any other benefits expected to accrue to the environment 
and local communities, including but not limited to improvements for 
mammals, birds, and other organisms and aquatic habitats;
    (vi) Discussion, with quantification and monetization, where 
possible, of any benefits expected to result from any reductions in 
thermal discharges from entrainment technologies.
    (12) Non-water Quality Environmental and Other Impacts Study. The 
owner or operator of an existing facility that withdraws greater than 
125 mgd AIF must develop for submission to the Director a detailed 
facility-specific discussion of the changes in non-water quality 
environmental and other impacts attributed to each technology and 
operational measure considered in paragraph (r)(10) of this section, 
including both impacts increased and impacts

[[Page 212]]

decreased. The study must include the following:
    (i) Estimates of changes to energy consumption, including but not 
limited to auxiliary power consumption and turbine backpressure energy 
penalty;
    (ii) Estimates of air pollutant emissions and of the human health 
and environmental impacts associated with such emissions;
    (iii) Estimates of changes in noise;
    (iv) A discussion of impacts to safety, including documentation of 
the potential for plumes, icing, and availability of emergency cooling 
water;
    (v) A discussion of facility reliability, including but not limited 
to facility availability, production of steam, impacts to production 
based on process unit heating or cooling, and reliability due to cooling 
water availability;
    (vi) Significant changes in consumption of water, including a 
facility-specific comparison of the evaporative losses of both once-
through cooling and closed-cycle recirculating systems, and 
documentation of impacts attributable to changes in water consumption; 
and
    (vii) A discussion of all reasonable attempts to mitigate each of 
these factors.
    (13) Peer Review. If the applicant is required to submit studies 
under paragraphs (r)(10) through (12) of this section, the applicant 
must conduct an external peer review of each report to be submitted with 
the permit application. The applicant must select peer reviewers and 
notify the Director in advance of the peer review. The Director may 
disapprove of a peer reviewer or require additional peer reviewers. The 
Director may confer with EPA, Federal, State and Tribal fish and 
wildlife management agencies with responsibility for fish and wildlife 
potentially affected by the cooling water intake structure, independent 
system operators, and state public utility regulatory agencies, to 
determine which peer review comments must be addressed. The applicant 
must provide an explanation for any significant reviewer comments not 
accepted. Peer reviewers must have appropriate qualifications and their 
names and credentials must be included in the peer review report.
    (14) New Units. The applicant must identify the chosen compliance 
method for the new unit. In addition, the owner or operator that selects 
the BTA standards for new units at 40 CFR 125.94 (e)(2) as its route to 
compliance must submit information to demonstrate entrainment reductions 
equivalent to 90 percent or greater of the reduction that could be 
achieved through compliance with 40 CFR 125.94(e)(1). The demonstration 
must include the Entrainment Characterization Study at paragraph (r)(9) 
of this section. In addition, if data specific to your facility 
indicates that compliance with the requirements of Sec. 125.94 of this 
chapter for each new unit would result in compliance costs wholly out of 
proportion to the costs EPA considered in establishing the requirements 
at issue, or would result in significant adverse impacts on local air 
quality, significant adverse impacts on local water resources other than 
impingement or entrainment, or significant adverse impacts on local 
energy markets, you must submit all supporting data as part of paragraph 
(r)(14) of this section. The Director may determine that additional data 
and information, including but not limited to monitoring, must be 
included as part of paragraph (r)(14) of this section.

    (a) Applications. All permit applications shall be signed as 
follows:
    (1) For a corporation. By a responsible corporate officer. For the 
purpose of this section, a responsible corporate officer means: (i) A 
president, secretary, treasurer, or vice-president of the corporation in 
charge of a principal business function, or any other person who perfoms 
similar policy- or decision-making functions for the corporation,

[[Page 213]]

or (ii) the manager of one or more manufacturing, production, or 
operating facilities, provided, the manager is authorized to make 
management decisions which govern the operation of the regulated 
facility including having the explicit or implicit duty of making major 
capital investment recommendations, and initiating and directing other 
comprehensive measures to assure long term environmental compliance with 
environmental laws and regulations; the manager can ensure that the 
necessary systems are established or actions taken to gather complete 
and accurate information for permit application requirements; and where 
authority to sign documents has been assigned or delegated to the 
manager in accordance with corporate procedures.
    Note: EPA does not require specific assignments or delegations of 
authority to responsible corporate officers identified in Sec. 
122.22(a)(1)(i). The Agency will presume that these responsible 
corporate officers have the requisite authority to sign permit 
applications unless the corporation has notified the Director to the 
contrary. Corporate procedures governing authority to sign permit 
applications may provide for assignment or delegation to applicable 
corporate positions under Sec. 122.22(a)(1)(ii) rather than to specific 
individuals.
    (2) For a partnership or sole proprietorship. By a general partner 
or the proprietor, respectively; or
    (3) For a municipality, State, Federal, or other public agency. By 
either a principal executive officer or ranking elected official. For 
purposes of this section, a principal executive officer of a Federal 
agency includes: (i) The chief executive officer of the agency, or (ii) 
a senior executive officer having responsibility for the overall 
operations of a principal geographic unit of the agency (e.g., Regional 
Administrators of EPA).
    (b) All reports required by permits, and other information requested 
by the Director shall be signed by a person described in paragraph (a) 
of this section, or by a duly authorized representative of that person. 
A person is a duly authorized representative only if:
    (1) The authorization is made in writing by a person described in 
paragraph (a) of this section;

responsibility for environmental matters for the company, (A duly 
authorized representative may thus be either a named individual or any 
individual occupying a named position.) and,
    (3) The written authorization is submitted to the Director.
    (c) Changes to authorization. If an authorization under paragraph 
(b) of this section is no longer accurate because a different individual 
or position has responsibility for the overall operation of the 
facility, a new authorization satisfying the requirements of paragraph 
(b) of this section must be submitted to the Director prior to or 
together with any reports, information, or applications to be signed by 
an authorized representative.
    (d) Certification. Any person signing a document under paragraph (a) 
or (b) of this section shall make the following certification:

    I certify under penalty of law that this document and all

Sec. 122.23  Concentrated animal feeding operations 
(applicable to State NPDES programs, see Sec. 123.25).

    (a) Scope. Concentrated animal feeding operations (CAFOs), as 
defined in paragraph (b) of this section or designated in accordance 
with paragraph (c) of this section, are point sources, subject to NPDES 
permitting requirements as provided in this section. Once an animal 
feeding operation is defined as a CAFO for at least one type of animal, 
the NPDES requirements for CAFOs apply with respect to all animals in 
confinement at the operation and all manure, litter, and process 
wastewater generated by those animals or the production of those 
animals, regardless of the type of animal.
    (b) Definitions applicable to this section:
    (1) Animal feeding operation (``AFO'') means a lot or facility 
(other than an aquatic animal production facility) where the following 
conditions are met:
    (i) Animals (other than aquatic animals) have been, are, or will be 
stabled or confined and fed or maintained for a total of 45 days or more 
in any 12-month period, and
    (ii) Crops, vegetation, forage growth, or post-harvest residues are 
not sustained in the normal growing season over any portion of the lot 
or facility.
    (2) Concentrated animal feeding operation (``CAFO'') means an AFO 
that is defined as a Large CAFO or as a Medium CAFO by the terms of this 
paragraph, or that is designated as a CAFO in accordance with paragraph 
(c) of this section. Two or more AFOs under common ownership are 
considered to be a single AFO for the purposes of determining the number 
of animals at an operation, if they adjoin each other or if they use a 
common area or system for the disposal of wastes.
    (3) The term land application area means land under the control of 
an AFO owner or operator, whether it is owned, rented, or leased, to 
which manure, litter or process wastewater from the production area is 
or may be applied.
    (4) Large concentrated animal feeding operation (``Large CAFO''). An 
AFO is defined as a Large CAFO if it stables or confines as many as or 
more than the numbers of animals specified in any of the following 
categories:
    (i) 700 mature dairy cows, whether milked or dry;
    (ii) 1,000 veal calves;
    (iii) 1,000 cattle other than mature dairy cows or veal calves. 
Cattle includes but is not limited to heifers, steers, bulls and cow/
calf pairs;
    (iv) 2,500 swine each weighing 55 pounds or more;
    (v) 10,000 swine each weighing less than 55 pounds;
    (vi) 500 horses;
    (vii) 10,000 sheep or lambs;
    (viii) 55,000 turkeys;
    (ix) 30,000 laying hens or broilers, if the AFO uses a liquid manure 
handling system;
    (x) 125,000 chickens (other than laying hens), if the AFO uses other 
than a liquid manure handling system;
    (xi) 82,000 laying hens, if the AFO uses other than a liquid manure 
handling system;
    (xii) 30,000 ducks (if the AFO uses other than a liquid manure 
handling system); or
    (xiii) 5,000 ducks (if the AFO uses a liquid manure handling 
system).
    (5) The term manure is defined to include manure, bedding, compost 
and raw materials or other materials commingled with manure or set aside 
for disposal.
    (6) Medium concentrated animal feeding operation (``Medium CAFO''). 
The term Medium CAFO includes any AFO with the type and number of 
animals that fall within any of the ranges listed in paragraph (b)(6)(i) 
of this section and which has been defined or designated as a CAFO. An 
AFO is defined as a Medium CAFO if:

    (ii) Either one of the following conditions are met:
    (A) Pollutants are discharged into waters of the United States 
through a man-made ditch, flushing system, or other similar man-made 
device; or
    (B) Pollutants are discharged directly into waters of the United 
States which originate outside of and pass over, across, or through the 
facility or otherwise come into direct contact with the animals confined 
in the operation.
    (7) Process wastewater means water directly or indirectly used in 
the operation of the AFO for any or all of the following: spillage or 
overflow from animal or poultry watering systems; washing, cleaning, or 
flushing pens, barns, manure pits, or other AFO facilities; direct 
contact swimming, washing, or spray cooling of animals; or dust control. 
Process wastewater also includes any water which comes into contact with 
any raw materials, products, or byproducts including manure, litter, 
feed, milk, eggs or bedding.
    (8) Production area means that part of an AFO that includes the 
animal confinement area, the manure storage area, the raw materials 
storage area, and the waste containment areas. The animal confinement 
area includes but is not limited to open lots, housed lots, feedlots,

    (9) Small concentrated animal feeding operation (``Small CAFO''). An 
AFO that is designated as a CAFO and is not a Medium CAFO.
    (c) How may an AFO be designated as a CAFO? The appropriate 
authority (i.e., State Director or Regional Administrator, or both, as 
specified in paragraph (c)(1) of this section) may designate any AFO as 
a CAFO upon determining that it is a significant contributor of 
pollutants to waters of the United States.
    (1) Who may designate?--(i) Approved States. In States that are 
approved or authorized by EPA under Part 123, CAFO designations may be 
made by the State Director. The Regional Administrator may also 
designate CAFOs in approved States, but only where the Regional 
Administrator has determined that one or more pollutants in the AFO's 
discharge contributes to an impairment in a downstream or adjacent State 
or Indian country water that is impaired for that pollutant.

[[Page 216]]

    (ii) States with no approved program. The Regional Administrator may 
designate CAFOs in States that do not have an approved program and in 
Indian country where no entity has expressly demonstrated authority and 
has been expressly authorized by EPA to implement the NPDES program.
    (2) In making this designation, the State Director or the Regional 
Administrator shall consider the following factors:
    (i) The size of the AFO and the amount of wastes reaching waters of 
the United States;
    (ii) The location of the AFO relative to waters of the United 
States;
    (iii) The means of conveyance of animal wastes and process waste 
waters into waters of the United States;
    (iv) The slope, vegetation, rainfall, and other factors affecting 
the likelihood or frequency of discharge of animal wastes manure and 
process waste waters into waters of the United States; and
    (v) Other relevant factors.
    (3) No AFO shall be designated under this paragraph unless the State 
Director or the Regional Administrator has conducted an on-site 
inspection of the operation and determined that the operation should and 
could be regulated under the permit program. In addition, no AFO with 
numbers of animals below those established in paragraph (b)(6) of this 
section may be designated as a CAFO unless:
    (i) Pollutants are discharged into waters of the United States 
through a manmade ditch, flushing system, or other similar manmade 
device; or
    (ii) Pollutants are discharged directly into waters of the United 
States which originate outside of the facility and pass over, across, or 
through the facility or otherwise come into direct contact with the 
animals confined in the operation.
    (d) NPDES permit authorization--(1) Permit Requirement. A CAFO must 
not discharge unless the discharge is authorized by an NPDES permit. In 
order to obtain authorization under an NPDES permit, the CAFO owner or 
operator must either apply for an individual NPDES permit or submit a 
notice of intent for coverage under an NPDES general permit.
    (2) Information to submit with permit application or notice of 
intent. An application for an individual permit must include the 
information specified in Sec. 122.21. A notice of intent for a general 
permit must include the information specified in Sec. Sec. 122.21 and 
122.28.
    (3) Information to submit with permit application. A permit 
application for an individual permit must include the information 
specified in Sec. 122.21. A notice of intent for a general permit must 
include the information specified in Sec. Sec. 122.21 and 122.28.
    (e) Land application discharges from a CAFO are subject to NPDES 
requirements. The discharge of manure, litter or process wastewater to 
waters of the United States from a CAFO as a result of the application 
of that manure, litter or process wastewater by the CAFO to land areas 
under its control is a discharge from that CAFO subject to NPDES permit 
requirements, except where it is an agricultural storm water discharge 
as provided in 33 U.S.C. 1362(14). For purposes of this paragraph, where 
the manure, litter or process wastewater has been applied in accordance 
with site specific nutrient management practices that ensure appropriate 
agricultural utilization of the nutrients in the manure, litter or 
process wastewater, as specified in Sec. 122.42(e)(1)(vi)-(ix), a 
precipitation-related discharge of manure, litter or process wastewater 
from land areas under the control of a CAFO is an agricultural 
stormwater discharge.
    (1) For unpermitted Large CAFOs, a precipitation-related discharge 
of manure, litter, or process wastewater from land areas under the 
control of a CAFO shall be considered an agricultural stormwater 
discharge only where the manure, litter, or process wastewater has been 
land applied in accordance with site-specific nutrient management 
practices that ensure appropriate agricultural utilization of the 
nutrients in the manure, litter, or process wastewater, as specified in 
Sec. 122.42(e)(1)(vi) through (ix).
    (2) Unpermitted Large CAFOs must maintain documentation specified in 
Sec. 122.42(e)(1)(ix) either on site or at a nearby office, or 
otherwise make such documentation readily available to the

[[Page 217]]

Director or Regional Administrator upon request.
    (f) By when must the owner or operator of a CAFO have an NPDES 
permit if it discharges? A CAFO must be covered by a permit at the time 
that it discharges.
    (g) [Reserved]
    (h) Procedures for CAFOs seeking coverage under a general permit. 
(1) CAFO owners or operators must submit a notice of intent when seeking 
authorization to discharge under a general permit in accordance with 
Sec. 122.28(b). The Director must review notices of intent submitted by 
CAFO owners or operators to ensure that the notice of intent includes 
the information required by Sec. 122.21(i)(1), including a nutrient 
management plan that meets the requirements of Sec. 122.42(e) and 
applicable effluent limitations and standards, including those specified 
in 40 CFR part 412. When additional information is necessary to complete 
the notice of intent or clarify, modify, or supplement previously 
submitted material, the Director may request such information from the 
owner or operator. If the Director makes a preliminary determination 
that the notice of intent meets the requirements of Sec. Sec. 
122.21(i)(1) and 122.42(e), the Director must notify the public of the 
Director's proposal to grant coverage under the permit to the CAFO and 
make available for public review and comment the notice of intent 
submitted by the CAFO, including the CAFO's nutrient management plan, 
and the draft terms of the nutrient management plan to be incorporated 
into the permit. The process for submitting public comments and hearing 
requests, and the hearing process if a request for a hearing is granted, 
must follow the procedures applicable to draft permits set forth in 40 
CFR 124.11 through 124.13. The Director may establish, either by 
regulation or in the general permit, an appropriate period of time for 
the public to comment and request a hearing that differs from the time 
period specified in 40 CFR 124.10. The Director must respond to 
significant comments received during the comment period, as provided in 
40 CFR 124.17, and, if necessary, require the CAFO owner or operator to 
revise the nutrient management plan in order to be granted permit 
coverage. When the Director authorizes coverage for the CAFO owner or 
operator under the general permit, the terms of the nutrient management 
plan shall become incorporated as terms and conditions of the permit for 
the CAFO. The Director shall notify the CAFO owner or operator and 
inform the public that coverage has been authorized and of the terms of 
the nutrient management plan incorporated as terms and conditions of the 
permit applicable to the CAFO.
    (2) For EPA-issued permits only. The Regional Administrator shall 
notify each person who has submitted written comments on the proposal to 
grant coverage and the draft terms of the nutrient management plan or 
requested notice of the final permit decision. Such notification shall 
include notice that coverage has been authorized and of the terms of the 
nutrient management plan incorporated as terms and conditions of the 
permit applicable to the CAFO.
    (3) Nothing in this paragraph (h) shall affect the authority of the 
Director to require an individual permit under Sec. 122.28(b)(3).

Sec. 122.24  Concentrated aquatic animal production facilities
(applicable to State NPDES programs, see Sec. 123.25).

    (a) Permit requirement. Concentrated aquatic animal production 
facilities, as defined in this section, are point sources subject to the 
NPDES permit program.
    (b) Definition. Concentrated aquatic animal production facility 
means a hatchery, fish farm, or other facility which meets the criteria 
in appendix C of this part, or which the Director designates under 
paragraph (c) of this section.
    (c) Case-by-case designation of concentrated aquatic animal 
production facilities. (1) The Director may designate any warm or cold 
water aquatic animal production facility as a concentrated aquatic 
animal production facility upon determining that it is a significant 
contributor of pollution to waters

[[Page 218]]

of the United States. In making this designation the Director shall 
consider the following factors:
    (i) The location and quality of the receiving waters of the United 
States;
    (ii) The holding, feeding, and production capacities of the 
facility;
    (iii) The quantity and nature of the pollutants reaching waters of 
the United States; and
    (iv) Other relevant factors.
    (2) A permit application shall not be required from a concentrated 
aquatic animal production facility designated under this paragraph until 
the Director has conducted on-site inspection of the facility and has 
determined that the facility should and could be regulated under the 
permit program.

Sec. 122.25  Aquaculture projects (applicable to State NPDES programs,
see Sec. 123.25).

    (a) Permit requirement. Discharges into aquaculture projects, as 
defined in this section, are subject to the NPDES permit program through 
section 318 of CWA, and in accordance with 40 CFR part 125, subpart B.
    (b) Definitions. (1) Aquaculture project means a defined managed 
water area which uses discharges of pollutants into that designated area 
for the maintenance or production of harvestable freshwater, estuarine, 
or marine plants or animals.
    (2) Designated project area means the portions of the waters of the 
United States within which the permittee or permit applicant plans to 
confine the cultivated species, using a method or plan or operation 
(including, but not limited to, physical confinement) which, on the 
basis of reliable scientific evidence, is expected to ensure that 
specific individual organisms comprising an aquaculture crop will enjoy 
increased growth attributable to the discharge of pollutants, and be 
harvested within a defined geographic area.



Sec. 122.26  Storm water discharges (applicable to State NPDES
programs, see Sec. 123.25).

    (a) Permit requirement. (1) Prior to October 1, 1994, discharges 
composed entirely of storm water shall not be required to obtain a NPDES 
permit except:
    (i) A discharge with respect to which a permit has been issued prior 
to February 4, 1987;
    (ii) A discharge associated with industrial activity (see Sec. 
122.26(a)(4));
    (iii) A discharge from a large municipal separate storm sewer 
system;
    (iv) A discharge from a medium municipal separate storm sewer 
system;
    (v) A discharge which the Director, or in States with approved NPDES 
programs, either the Director or the EPA Regional Administrator, 
determines to contribute to a violation of a water quality standard or 
is a significant contributor of pollutants to waters of the United 
States. This designation may include a discharge from any conveyance or 
system of conveyances used for collecting and conveying storm water 
runoff or a system of discharges from municipal separate storm sewers, 
except for those discharges from conveyances which do not require a 
permit under paragraph (a)(2) of this section or agricultural storm 
water runoff which is exempted from the definition of point source at 
Sec. 122.2.

The Director may designate discharges from municipal separate storm 
sewers on a system-wide or jurisdiction-wide basis. In making this 
determination the Director may consider the following factors:
    (A) The location of the discharge with respect to waters of the 
United States as defined at 40 CFR 122.2.
    (B) The size of the discharge;
    (C) The quantity and nature of the pollutants discharged to waters 
of the United States; and
    (D) Other relevant factors.
    (2) The Director may not require a permit for discharges of storm 
water runoff from the following:
    (i) Mining operations composed entirely of flows which are from 
conveyances or systems of conveyances (including but not limited to 
pipes, conduits, ditches, and channels) used for collecting and 
conveying precipitation runoff and which are not contaminated by contact 
with or that have not come into contact with, any overburden, raw 
material, intermediate products, finished product, byproduct, or waste

[[Page 219]]

products located on the site of such operations, except in accordance 
with paragraph (c)(1)(iv) of this section.
    (ii) All field activities or operations associated with oil and gas 
exploration, production, processing, or treatment operations or 
transmission facilities, including activities necessary to prepare a 
site for drilling and for the movement and placement of drilling 
equipment, whether or not such field activities or operations may be 
considered to be construction activities, except in accordance with 
paragraph (c)(1)(iii) of this section. Discharges of sediment from 
construction activities associated with oil and gas exploration, 
production, processing, or treatment operations or transmission 
facilities are not subject to the provisions of paragraph (c)(1)(iii)(C) 
of this section.

    Note to paragraph (a)(2)(ii):
    EPA encourages operators of oil and gas field activities or 
operations to implement and maintain Best Management Practices (BMPs) to 
minimize discharges of pollutants, including sediment, in storm water 
both during and after construction activities to help ensure protection 
of surface water quality during storm events. Appropriate controls would 
be those suitable to the site conditions and consistent with generally 
accepted engineering design criteria and manufacturer specifications. 
Selection of BMPs could also be affected by seasonal or climate 
conditions.

    (3) Large and medium municipal separate storm sewer systems. (i) 
Permits must be obtained for all discharges from large and medium 
municipal separate storm sewer systems.
    (ii) The Director may either issue one system-wide permit covering 
all discharges from municipal separate storm sewers within a large or 
medium municipal storm sewer system or issue distinct permits for 
appropriate categories of discharges within a large or medium municipal 
separate storm sewer system including, but not limited to: all 
discharges owned or operated by the same municipality; located within 
the same jurisdiction; all discharges within a system that discharge to 
the same watershed; discharges within a system that are similar in 
nature; or for individual discharges from municipal separate storm 
sewers within the system.
    (iii) The operator of a discharge from a municipal separate storm 
sewer which is part of a large or medium municipal separate storm sewer 
system must either:
    (A) Participate in a permit application (to be a permittee or a co-
permittee) with one or more other operators of discharges from the large 
or medium municipal storm sewer system which covers all, or a portion of 
all, discharges from the municipal separate storm sewer system;
    (B) Submit a distinct permit application which only covers 
discharges from the municipal separate storm sewers for which the 
operator is responsible; or
    (C) A regional authority may be responsible for submitting a permit 
application under the following guidelines:
    (1) The regional authority together with co-applicants shall have 
authority over a storm water management program that is in existence, or 
shall be in existence at the time part 1 of the application is due;
    (2) The permit applicant or co-applicants shall establish their 
ability to make a timely submission of part 1 and part 2 of the 
municipal application;
    (3) Each of the operators of municipal separate storm sewers within 
the systems described in paragraphs (b)(4) (i), (ii), and (iii) or 
(b)(7) (i), (ii), and (iii) of this section, that are under the purview 
of the designated regional authority, shall comply with the application 
requirements of paragraph (d) of this section.
    (iv) One permit application may be submitted for all or a portion of 
all municipal separate storm sewers within adjacent or interconnected 
large or medium municipal separate storm sewer systems. The Director may 
issue one system-wide permit covering all, or a portion of all municipal 
separate storm sewers in adjacent or interconnected large or medium 
municipal separate storm sewer systems.
    (v) Permits for all or a portion of all discharges from large or 
medium municipal separate storm sewer systems that are issued on a 
system-wide, jurisdiction-wide, watershed or other basis may specify 
different conditions relating to different discharges covered by

[[Page 220]]

the permit, including different management programs for different 
drainage areas which contribute storm water to the system.
    (vi) Co-permittees need only comply with permit conditions relating 
to discharges from the municipal separate storm sewers for which they 
are operators.
    (4) Discharges through large and medium municipal separate storm 
sewer systems. In addition to meeting the requirements of paragraph (c) 
of this section, an operator of a storm water discharge associated with 
industrial activity which discharges through a large or medium municipal 
separate storm sewer system shall submit, to the operator of the 
municipal separate storm sewer system receiving the discharge no later 
than May 15, 1991, or 180 days prior to commencing such discharge: the 
name of the facility; a contact person and phone number; the location of 
the discharge; a description, including Standard Industrial 
Classification, which best reflects the principal products or services 
provided by each facility; and any existing NPDES permit number.
    (5) Other municipal separate storm sewers. The Director may issue 
permits for municipal separate storm sewers that are designated under 
paragraph (a)(1)(v) of this section on a system-wide basis, 
jurisdiction-wide basis, watershed basis or other appropriate basis, or 
may issue permits for individual discharges.
    (6) Non-municipal separate storm sewers. For storm water discharges 
associated with industrial activity from point sources which discharge 
through a non-municipal or non-publicly owned separate storm sewer 
system, the Director, in his discretion, may issue: a single NPDES 
permit, with each discharger a co-permittee to a permit issued to the 
operator of the portion of the system that discharges into waters of the 
United States; or, individual permits to each discharger of storm water 
associated with industrial activity through the non-municipal conveyance 
system.
    (i) All storm water discharges associated with industrial activity 
that discharge through a storm water discharge system that is not a 
municipal separate storm sewer must be covered by an individual permit, 
or a permit issued to the operator of the portion of the system that 
discharges to waters of the United States, with each discharger to the 
non-municipal conveyance a co-permittee to that permit.
    (ii) Where there is more than one operator of a single system of 
such conveyances, all operators of storm water discharges associated 
with industrial activity must submit applications.
    (iii) Any permit covering more than one operator shall identify the 
effluent limitations, or other permit conditions, if any, that apply to 
each operator.
    (7) Combined sewer systems. Conveyances that discharge storm water 
runoff combined with municipal sewage are point sources that must obtain 
NPDES permits in accordance with the procedures of Sec. 122.21 and are 
not subject to the provisions of this section.
    (8) Whether a discharge from a municipal separate storm sewer is or 
is not subject to regulation under this section shall have no bearing on 
whether the owner or operator of the discharge is eligible for funding 
under title II, title III or title VI of the Clean Water Act. See 40 CFR 
part 35, subpart I, appendix A(b)H.2.j.
    (9)(i) On and after October 1, 1994, for discharges composed 
entirely of storm water, that are not required by paragraph (a)(1) of 
this section to obtain a permit, operators shall be required to obtain a 
NPDES permit only if:
    (A) The discharge is from a small MS4 required to be regulated 
pursuant to Sec. 122.32;
    (B) The discharge is a storm water discharge associated with small 
construction activity pursuant to paragraph (b)(15) of this section;
    (C) The Director, or in States with approved NPDES programs either 
the Director or the EPA Regional Administrator, determines that storm 
water controls are needed for the discharge based on wasteload 
allocations that are part of ``total maximum daily loads'' (TMDLs) that 
address the pollutant(s) of concern; or
    (D) The Director, or in States with approved NPDES programs either 
the Director or the EPA Regional Administrator, determines that the 
discharge,

[[Page 221]]

or category of discharges within a geographic area, contributes to a 
violation of a water quality standard or is a significant contributor of 
pollutants to waters of the United States.
    (ii) Operators of small MS4s designated pursuant to paragraphs 
(a)(9)(i)(A), (a)(9)(i)(C), and (a)(9)(i)(D) of this section shall seek 
coverage under an NPDES permit in accordance with Sec. Sec. 122.33 
through 122.35. Operators of non-municipal sources designated pursuant 
to paragraphs (a)(9)(i)(B), (a)(9)(i)(C), and (a)(9)(i)(D) of this 
section shall seek coverage under an NPDES permit in accordance with 
paragraph (c)(1) of this section.
    (iii) Operators of storm water discharges designated pursuant to 
paragraphs (a)(9)(i)(C) and (a)(9)(i)(D) of this section shall apply to 
the Director for a permit within 180 days of receipt of notice, unless 
permission for a later date is granted by the Director (see Sec. 
124.52(c) of this chapter).
    (b) Definitions. (1) Co-permittee means a permittee to a NPDES 
permit that is only responsible for permit conditions relating to the 
discharge for which it is operator.
    (2) Illicit discharge means any discharge to a municipal separate 
storm sewer that is not composed entirely of storm water except 
discharges pursuant to a NPDES permit (other than the NPDES permit for 
discharges from the municipal separate storm sewer) and discharges 
resulting from fire fighting activities.
    (3) Incorporated place means the District of Columbia, or a city, 
town, township, or village that is incorporated under the laws of the 
State in which it is located.
    (4) Large municipal separate storm sewer system means all municipal 
separate storm sewers that are either:
    (i) Located in an incorporated place with a population of 250,000 or 
more as determined by the 1990 Decennial Census by the Bureau of the 
Census (Appendix F of this part); or
    (ii) Located in the counties listed in appendix H, except municipal 
separate storm sewers that are located in the incorporated places, 
townships or towns within such counties; or
    (iii) Owned or operated by a municipality other than those described 
in paragraph (b)(4) (i) or (ii) of this section and that are designated 
by the Director as part of the large or medium municipal separate storm 
sewer system due to the interrelationship between the discharges of the 
designated storm sewer and the discharges from municipal separate storm 
sewers described under paragraph (b)(4) (i) or (ii) of this section. In 
making this determination the Director may consider the following 
factors:
    (A) Physical interconnections between the municipal separate storm 
sewers;
    (B) The location of discharges from the designated municipal 
separate storm sewer relative to discharges from municipal separate 
storm sewers described in paragraph (b)(4)(i) of this section;

separate storm sewer system, municipal separate storm sewers located 
within the boundaries of a region defined by a storm water management 
regional authority based on a jurisdictional, watershed, or other 
appropriate basis that includes one or more of the systems described in 
paragraph (b)(4) (i), (ii), (iii) of this section.
    (5) Major municipal separate storm sewer outfall (or ``major 
outfall'') means a municipal separate storm sewer outfall that 
discharges from a single pipe with an inside diameter of 36 inches or 
more or its equivalent (discharge from a single conveyance other than 
circular pipe which is associated with a drainage area of more than 50 
acres); or for municipal separate storm sewers that receive storm water 
from lands zoned for industrial activity (based on comprehensive zoning 
plans or the equivalent), an outfall that discharges from a single pipe 
with an inside diameter of 12 inches or more or from its equivalent 
(discharge from other than a circular pipe associated with a drainage 
area of 2 acres or more).
    (6) Major outfall means a major municipal separate storm sewer 
outfall.

[[Page 222]]

    (7) Medium municipal separate storm sewer system means all municipal 
separate storm sewers that are either:
    (i) Located in an incorporated place with a population of 100,000 or 
more but less than 250,000, as determined by the 1990 Decennial Census 
by the Bureau of the Census (appendix G of this part); or
    (ii) Located in the counties listed in appendix I, except municipal 
separate storm sewers that are located in the incorporated places, 
townships or towns within such counties; or
    (iii) Owned or operated by a municipality other than those described 
in paragraph (b)(7) (i) or (ii) of this section and that are designated 
by the Director as part of the large or medium municipal separate storm 
sewer system due to the interrelationship between the discharges of the 
designated storm sewer and the discharges from municipal separate storm 
sewers described under paragraph (b)(7) (i) or (ii) of this section. In

code--of--federal--regulations/ibr--locations.html. An operator must 
certify to the Director that the construction activity will take place 
during a period when the value of the rainfall erosivity factor is less 
than five; or
    (B) Storm water controls are not needed based on a ``total maximum 
daily load'' (TMDL) approved or established by EPA that addresses the 
pollutant(s) of concern or, for non-impaired waters that do not require 
TMDLs, an equivalent analysis that determines allocations for small 
construction sites for the pollutant(s) of concern or that determines 
that such allocations are not needed to protect water quality based on 
consideration of existing in-stream concentrations, expected growth in 
pollutant contributions from all sources, and a margin of safety. For 
the purpose of this paragraph, the pollutant(s) of concern include 
sediment or a parameter that addresses sediment (such as total suspended 
solids, turbidity or siltation) and any other pollutant that has been 
identified as a cause of impairment of any water body that will receive 
a discharge from the construction activity. The operator must certify to 
the Director that the construction activity will take place, and storm 
water discharges will occur, within the drainage area addressed by the 
TMDL or equivalent analysis.
    (C) As of December 21, 2020 all certifications submitted in 
compliance with paragraphs (b)(15)(i)(A) and (B) of this section must be 
submitted electronically by the owner or operator to the Director or 
initial recipient, as defined in 40 CFR 127.2(b), in compliance with 
this section and 40 CFR part 3 (including, in all cases, subpart D to 
part 3), Sec. 122.22, and 40 CFR part 127. Part 127 is not intended to 
undo existing requirements for electronic reporting. Prior to this date, 
and independent of part 127, owners or operators may be required to 
report electronically if specified by a particular permit or if required 
to do so by state law.
    (ii) Any other construction activity designated by the Director, or 
in States with approved NPDES programs either the Director or the EPA 
Regional Administrator, based on the potential for contribution to a 
violation of a water quality standard or for significant contribution of 
pollutants to waters of the United States.

a grid over a drainage system map and identifying those cells of the 
grid which contain a segment of the storm sewer system or major outfall. 
The field screening points shall be established using the following 
guidelines and criteria:
    (1) A grid system consisting of perpendicular north-south and east-
west lines spaced \1/4\ mile apart shall be overlayed on a map of the 
municipal storm sewer system, creating a series of cells;
    (2) All cells that contain a segment of the storm sewer system shall 
be identified; one field screening point shall be selected in each cell; 
major outfalls may be used as field screening points;
    (3) Field screening points should be located downstream of any 
sources of suspected illegal or illicit activity;
    (4) Field screening points shall be located to the degree 
practicable at the farthest manhole or other accessible location 
downstream in the system, within each cell; however, safety of personnel 
and accessibility of the location should be considered in making this 
determination;

population density of the site; traffic density; age of the structures 
or buildings in the area; history of the area; and land use types;
    (6) For medium municipal separate storm sewer systems, no more than 
250 cells need to have identified field screening points; in large 
municipal separate storm sewer systems, no more than 500 cells need to 
have identified field screening points; cells established by the grid 
that contain no storm sewer segments will be eliminated from 
consideration; if fewer than 250 cells in medium municipal sewers are 
created, and fewer than 500 in large systems are created by the overlay 
on the municipal sewer map, then all those cells which contain a segment 
of the sewer system shall be subject to field screening (unless access 
to the separate storm sewer system is impossible); and
    (7) Large or medium municipal separate storm sewer systems which are 
unable to utilize the procedures described in paragraphs (d)(1)(iv)(D) 
(1) through (6) of this section, because a sufficiently detailed map of 
the separate storm sewer systems is unavailable, shall field screen no 
more than 500 or 250 major outfalls respectively (or all major outfalls 
in the system, if less); in such circumstances, the applicant shall 
establish a grid system consisting of north-south and east-west lines 
spaced \1/4\ mile apart as an overlay to the boundaries of the municipal 
storm sewer system, thereby creating a series of cells; the applicant 
will then select major outfalls in as many cells as possible until at 
least 500 major outfalls (large municipalities) or 250 major outfalls 
(medium municipalities) are selected; a field screening analysis shall 
be undertaken at these major outfalls.
    (E) Characterization plan. Information and a proposed program to 
meet the requirements of paragraph (d)(2)(iii) of this section. Such 
description shall include: the location of outfalls or field screening

field screening point is representative, the seasons during which 
sampling is intended, a description of the sampling equipment. The 
proposed location of outfalls or field screening points for such 
sampling should reflect water quality concerns (see paragraph

[[Page 231]]

(d)(1)(iv)(C) of this section) to the extent practicable.

    (7) The Director shall issue or deny permits for discharges composed 
entirely of storm water under this section in accordance with the 
following schedule:
    (i)(A) Except as provided in paragraph (e)(7)(i)(B) of this section, 
the Director shall issue or deny permits for storm water discharges 
associated with industrial activity no later than October 1, 1993, or, 
for new sources or existing sources which fail to submit a complete 
permit application by October 1, 1992, one year after receipt of a 
complete permit application;

[[Page 237]]

    (B) For any municipality with a population of less than 250,000 
which submits a timely Part I group application under paragraph 
(e)(2)(i)(B) of this section, the Director shall issue or deny permits 
for storm water discharges associated with industrial activity no later 
than May 17, 1994, or, for any such municipality which fails to submit a 
complete Part II group permit application by May 17, 1993, one year 
after receipt of a complete permit application;
    (ii) The Director shall issue or deny permits for large municipal 
separate storm sewer systems no later than November 16, 1993, or, for 
new sources or existing sources which fail to submit a complete permit 
application by November 16, 1992, one year after receipt of a complete 
permit application;
    (iii) The Director shall issue or deny permits for medium municipal 
separate storm sewer systems no later than May 17, 1994, or, for new 
sources or existing sources which fail to submit a complete permit 
application by May 17, 1993, one year after receipt of a complete permit 
application.
    (8) For any storm water discharge associated with small construction 
activities identified in paragraph (b)(15)(i) of this section, see Sec. 
122.21(c)(1). Discharges from these sources require permit authorization 
by March 10, 2003, unless designated for coverage before then.
    (9) For any discharge from a regulated small MS4, the permit 
application made under Sec. 122.33 must be submitted to the Director 
by:
    (i) March 10, 2003 if designated under Sec. 122.32(a)(1) unless 
your MS4 serves a jurisdiction with a population under 10,000 and the 
NPDES permitting authority has established a phasing schedule under 
Sec. 123.35(d)(3) (see Sec. 122.33(c)(1)); or
    (ii) Within 180 days of notice, unless the NPDES permitting 
authority grants a later date, if designated under Sec. 122.32(a)(2) 
(see Sec. 122.33(c)(2)).
    (f) Petitions. (1) Any operator of a municipal separate storm sewer 
system may petition the Director to require a separate NPDES permit (or 
a permit issued under an approved NPDES State program) for any discharge 
into the municipal separate storm sewer system.
    (2) Any person may petition the Director to require a NPDES permit 
for a discharge which is composed entirely of storm water which 
contributes to a violation of a water quality standard or is a 
significant contributor of pollutants to waters of the United States.
    (3) The owner or operator of a municipal separate storm sewer system 
may petition the Director to reduce the Census estimates of the 
population served by such separate system to account for storm water 
discharged to combined sewers as defined by 40 CFR 35.2005(b)(11) that 
is treated in a publicly owned treatment works. In municipalities in 
which combined sewers are operated, the Census estimates of population 
may be reduced proportional to the fraction, based on estimated lengths, 
of the length of combined sewers over the sum of the length of combined 
sewers and municipal separate storm sewers where an applicant has 
submitted the NPDES permit number associated with each discharge point 
and a map indicating areas served by combined sewers and the location of 
any combined sewer overflow discharge point.
    (4) Any person may petition the Director for the designation of a 
large, medium, or small municipal separate storm sewer system as defined 
by paragraph (b)(4)(iv), (b)(7)(iv), or (b)(16) of this section.
    (5) The Director shall make a final determination on any petition 
received under this section within 90 days after receiving the petition 
with the exception of petitions to designate a small MS4 in which case 
the Director shall make a final determination on the petition within 180 
days after its receipt.
    (g) Conditional exclusion for ``no exposure'' of industrial 
activities and materials to storm water. Discharges composed entirely of 
storm water are not storm water discharges associated with industrial 
activity if there is ``no exposure'' of industrial materials and 
activities to rain, snow, snowmelt and/or runoff, and the discharger 
satisfies the conditions in paragraphs (g)(1) through (g)(4) of this 
section. ``No exposure'' means that all industrial materials and 
activities are protected by a storm resistant shelter to prevent 
exposure to

[[Page 238]]

rain, snow, snowmelt, and/or runoff. Industrial materials or activities 
include, but are not limited to, material handling equipment or 
activities, industrial machinery, raw materials, intermediate products, 
by-products, final products, or waste products. Material handling 
activities include the storage, loading and unloading, transportation, 
or conveyance of any raw material, intermediate product, final product 
or waste product.
    (1) Qualification. To qualify for this exclusion, the operator of 
the discharge must:
    (i) Provide a storm resistant shelter to protect industrial 
materials and activities from exposure to rain, snow, snow melt, and 
runoff;
    (ii) Complete and sign (according to Sec. 122.22) a certification 
that there are no discharges of storm water contaminated by exposure to 
industrial materials and activities from the entire facility, except as 
provided in paragraph (g)(2) of this section;
    (iii) Submit the signed certification to the NPDES permitting 
authority once every five years. As of December 21, 2020 all 
certifications submitted in compliance with this section must be 
submitted electronically by the owner or operator to the Director or 
initial recipient, as defined in 40 CFR 127.2(b), in compliance with 
this section and 40 CFR part 3 (including, in all cases, subpart D to 
part 3), Sec. 122.22, and 40 CFR part 127. Part 127 is not intended to 
undo existing requirements for electronic reporting. Prior to this date, 
and independent of part 127, owners or operators may be required to 
report electronically if specified by a particular permit or if required 
to do so by state law.
    (iv) Allow the Director to inspect the facility to determine 
compliance with the ``no exposure'' conditions;
    (v) Allow the Director to make any ``no exposure'' inspection 
reports available to the public upon request; and
    (vi) For facilities that discharge through an MS4, upon request, 
submit a copy of the certification of ``no exposure'' to the MS4 
operator, as well as allow inspection and public reporting by the MS4 
operator.
    (2) Industrial materials and activities not requiring storm 
resistant shelter. To qualify for this exclusion, storm resistant 
shelter is not required for:
    (i) Drums, barrels, tanks, and similar containers that are tightly 
sealed, provided those containers are not deteriorated and do not leak 
(``Sealed'' means banded or otherwise secured and without operational 
taps or valves);
    (ii) Adequately maintained vehicles used in material handling; and
    (iii) Final products, other than products that would be mobilized in 
storm water discharge (e.g., rock salt).
    (3) Limitations. (i) Storm water discharges from construction 
activities identified in paragraphs (b)(14)(x) and (b)(15) are not 
eligible for this conditional exclusion.
    (ii) This conditional exclusion from the requirement for an NPDES 
permit is available on a facility-wide basis only, not for individual 
outfalls. If a facility has some discharges of storm water that would 
otherwise be ``no exposure'' discharges, individual permit requirements 
should be adjusted accordingly.
    (iii) If circumstances change and industrial materials or activities 
become exposed to rain, snow, snow melt, and/or runoff, the conditions 
for this exclusion no longer apply. In such cases, the discharge becomes 
subject to enforcement for un-permitted discharge. Any conditionally 
exempt discharger who anticipates changes in circumstances should apply 
for and obtain permit authorization prior to the change of 
circumstances.
    (iv) Notwithstanding the provisions of this paragraph, the NPDES 
permitting authority retains the authority to require permit 
authorization (and deny this exclusion) upon making a determination that 
the discharge causes, has a reasonable potential to cause, or 
contributes to an instream excursion above an applicable water quality 
standard, including designated uses.
    (4) Certification. The no exposure certification must require the 
submission of the following information, at a minimum, to aid the NPDES 
permitting authority in determining if the facility qualifies for the no 
exposure exclusion:
    (i) The legal name, address and phone number of the discharger (see 
Sec. 122.21(b));

[[Page 239]]

    (ii) The facility name and address, the county name and the latitude 
and longitude where the facility is located;
    (iii) The certification must indicate that none of the following 
materials or activities are, or will be in the foreseeable future, 
exposed to precipitation:
    (A) Using, storing or cleaning industrial machinery or equipment, 
and areas where residuals from using, storing or cleaning industrial 
machinery or equipment remain and are exposed to storm water;
    (B) Materials or residuals on the ground or in storm water inlets 
from spills/leaks;
    (C) Materials or products from past industrial activity;
    (D) Material handling equipment (except adequately maintained 
vehicles);
    (E) Materials or products during loading/unloading or transporting 
activities;
    (F) Materials or products stored outdoors (except final products 
intended for outside use, e.g., new cars, where exposure to storm water 
does not result in the discharge of pollutants);
    (G) Materials contained in open, deteriorated or leaking storage 
drums, barrels, tanks, and similar containers;
    (H) Materials or products handled/stored on roads or railways owned 
or maintained by the discharger;
    (I) Waste material (except waste in covered, non-leaking containers, 
e.g., dumpsters);
    (J) Application or disposal of process wastewater (unless otherwise 
permitted); and
    (K) Particulate matter or visible deposits of residuals from roof 
stacks/vents not otherwise regulated, i.e., under an air quality control 
permit, and evident in the storm water outflow;
    (iv) All ``no exposure'' certifications must include the following 
certification statement, and be signed in accordance with the signatory 
requirements of Sec. 122.22: ``I certify under penalty of law that I 
have read and understand the eligibility requirements for claiming a 
condition of ``no exposure'' and obtaining an exclusion from NPDES storm 
water permitting; and that there are no discharges of storm water 
contaminated by exposure to industrial activities or materials from the 
industrial facility identified in this document (except as allowed under 
paragraph (g)(2)) of this section. I understand that I am obligated to 
submit a no exposure certification form once every five years to the 
NPDES permitting authority and, if requested, to the operator of the 
local MS4 into which this facility discharges (where applicable). I 
understand that I must allow the NPDES permitting authority, or MS4 
operator where the discharge is into the local MS4, to perform 
inspections to confirm the condition of no exposure and to make such 
inspection reports publicly available upon request. I understand that I 
must obtain coverage under an NPDES permit prior to any point source 
discharge of storm water from the facility. I certify under penalty of 
law that this document and all attachments were prepared under my 
direction or supervision in accordance with a system designed to assure 
that qualified personnel properly gathered and evaluated the information 
submitted. Based upon my inquiry of the person or persons who manage the 
system, or those persons directly involved in gathering the information, 
the information submitted is to the best of my knowledge and belief 
true, accurate and complete. I am aware there are significant penalties 
for submitting false information, including the possibility of fine and 
imprisonment for knowing violations.''

Sec. 122.27  Silvicultural activities (applicable to State NPDES
programs, see Sec. 123.25).

    (a) Permit requirement. Silvicultural point sources, as defined in 
this section, as point sources subject to the NPDES permit program.
    (b) Definitions. (1) Silvicultural point source means any 
discernible, confined and discrete conveyance related to rock crushing, 
gravel washing, log sorting, or log storage facilities which are 
operated in connection with silvicultural activities and from which 
pollutants are discharged into waters

[[Page 240]]

of the United States. The term does not include non-point source 
silvicultural activities such as nursery operations, site preparation, 
reforestation and subsequent cultural treatment, thinning, prescribed 
burning, pest and fire control, harvesting operations, surface drainage, 
or road construction and maintenance from which there is natural runoff. 
However, some of these activities (such as stream crossing for roads) 
may involve point source discharges of dredged or fill material which 
may require a CWA section 404 permit (See 33 CFR 209.120 and part 233).
    (2) Rock crushing and gravel washing facilities means facilities 
which process crushed and broken stone, gravel, and riprap (See 40 CFR 
part 436, subpart B, including the effluent limitations guidelines).
    (3) Log sorting and log storage facilities means facilities whose 
discharges result from the holding of unprocessed wood, for example, 
logs or roundwood with bark or after removal of bark held in self-
contained bodies of water (mill ponds or log ponds) or stored on land 
where water is applied intentionally on the logs (wet decking). (See 40 
CFR part 429, subpart I, including the effluent limitations guidelines).



Sec. 122.28  General permits (applicable to State NPDES programs,
see Sec. 123.25).

    (a) Coverage. The Director may issue a general permit in accordance 
with the following:
    (1) Area. The general permit shall be written to cover one or more 
categories or subcategories of discharges or sludge use or disposal 
practices or facilities described in the permit under paragraph 
(a)(2)(ii) of this section, except those covered by individual permits, 
within a geographic area. The area should correspond to existing 
geographic or political boundaries such as:
    (i) Designated planning areas under sections 208 and 303 of CWA;
    (ii) Sewer districts or sewer authorities;
    (iii) City, county, or State political boundaries;
    (iv) State highway systems;
    (v) Standard metropolitan statistical areas as defined by the Office 
of Management and Budget;
    (vi) Urbanized areas as designated by the Bureau of the Census 
according to criteria in 30 FR 15202 (May 1, 1974); or
    (vii) Any other appropriate division or combination of boundaries.
    (2) Sources. The general permit may be written to regulate one or 
more categories or subcategories of discharges or sludge use or disposal 
practices or facilities, within the area described in paragraph (a)(1) 
of this section, where the sources within a covered subcategory of 
discharges are either:
    (i) Storm water point sources; or (ii) One or more categories or 
subcategories of point sources other than storm water point sources, or 
one or more categories or subcategories of ``treatment works treating 
domestic sewage'', if the sources or ``treatment works treating domestic 
sewage'' within each category or subcategory all:
    (A) Involve the same or substantially similar types of operations;
    (B) Discharge the same types of wastes or engage in the same types 
of sludge use or disposal practices;
    (C) Require the same effluent limitations, operating conditions, or 
standards for sewage sludge use or disposal;
    (D) Require the same or similar monitoring; and (E) In the opinion 
of the Director, are more appropriately controlled under a general 
permit than under individual permits.
    (3)Water quality-based limits. Where sources within a specific 
category or subcategory of dischargers are subject to water quality-
based limits imposed pursuant to Sec. 122.44, the sources in that 
specific category or subcategory shall be subject to the same water 
quality-based effluent limitations.
    (4) Other requirements. (i) The general permit must clearly identify 
the applicable conditions for each category or subcategory of 
dischargers or treatment works treating domestic sewage covered by the 
permit.
    (ii) The general permit may exclude specified sources or areas from 
coverage.
    (b) Administration--(1) In general. General permits may be issued, 
modified, revoked and reissued, or terminated in

[[Page 241]]

accordance with applicable requirements of part 124 of this chapter or 
corresponding State regulations. Special procedures for issuance are 
found at Sec. 123.44 of this chapter for States.
    (2) Authorization to discharge, or authorization to engage in sludge 
use and disposal practices. (i) Except as provided in paragraphs 
(b)(2)(v) and (vi) of this section, dischargers (or treatment works 
treating domestic sewage) seeking coverage under a general permit shall 
submit to the Director a notice of intent to be covered by the general 
permit. A discharger (or treatment works treating domestic sewage) who 
fails to submit a notice of intent in accordance with the terms of the 
permit is not authorized to discharge, (or in the case of sludge 
disposal permit, to engage in a sludge use or disposal practice), under 
the terms of the general permit unless the general permit, in accordance 
with paragraph (b)(2)(v), contains a provision that a notice of intent 
is not required or the Director notifies a discharger (or treatment 
works treating domestic sewage) that it is covered by a general permit 
in accordance with paragraph (b)(2)(vi). A complete and timely, notice 
of intent (NOI), to be covered in accordance with general permit 
requirements, fulfills the requirements for permit applications for 
purposes of Sec. Sec. 122.6, 122.21, and 122.26. As of December 21, 
2020 all notices of intent submitted in compliance with this section 
must be submitted electronically by the discharger (or treatment works 
treating domestic sewage) to the Director or initial recipient, as 
defined in 40 CFR 127.2(b), in compliance with this section and 40 CFR 
part 3 (including, in all cases, subpart D to part 3), Sec. 122.22, and 
40 CFR part 127. Part 127 is not intended to undo existing requirements 
for electronic reporting. Prior to this date, and independent of part 
127, discharger (or treatment works treating domestic sewage) may be 
required to report electronically if specified by a particular permit or 
if required to do so by state law.
    (ii) The contents of the notice of intent shall be specified in the 
general permit and shall require the submission of information necessary 
for adequate program implementation, including at a minimum, the legal 
name and address of the owner or operator, the facility name and 
address, type of facility or discharges, the receiving stream(s), and 
other required data elements as identified in appendix A to part 127. 
General permits for stormwater discharges associated with industrial 
activity from inactive mining, inactive oil and gas operations, or 
inactive landfills occurring on Federal lands where an operator cannot 
be identified may contain alternative notice of intent requirements. All 
notices of intent shall be signed in accordance with Sec. 122.22. 
Notices of intent for coverage under a general permit for concentrated 
animal feeding operations must include the information specified in 
Sec. 122.21(i)(1), including a topographic map.
    (iii) General permits shall specify the deadlines for submitting 
notices of intent to be covered and the date(s) when a discharger is 
authorized to discharge under the permit;
    (iv) General permits shall specify whether a discharger (or 
treatment works treating domestic sewage) that has submitted a complete 
and timely notice of intent to be covered in accordance with the general 
permit and that is eligible for coverage under the permit, is authorized 
to discharge, (or in the case of a sludge disposal permit, to engage in 
a sludge use or disposal practice), in accordance with the permit either 
upon receipt of the notice of intent by the Director, after a waiting 
period specified in the general permit, on a date specified in the 
general permit, or upon receipt of notification of inclusion by the 
Director. Coverage may be terminated or revoked in accordance with 
paragraph (b)(3) of this section.
    (v) Discharges other than discharges from publicly owned treatment 
works, combined sewer overflows, municipal separate storm sewer systems, 
primary industrial facilities, and storm water discharges associated 
with industrial activity, may, at the discretion of the Director, be 
authorized to discharge under a general permit without submitting a 
notice of intent where the Director finds that a notice of intent 
requirement would be inappropriate. In making such a finding, the 
Director shall consider: the type of discharge;

[[Page 242]]

the expected nature of the discharge; the potential for toxic and 
conventional pollutants in the discharges; the expected volume of the 
discharges; other means of identifying discharges covered by the permit; 
and the estimated number of discharges to be covered by the permit. The 
Director shall provide in the public notice of the general permit the 
reasons for not requiring a notice of intent.
    (vi) The Director may notify a discharger (or treatment works 
treating domestic sewage) that it is covered by a general permit, even 
if the discharger (or treatment works treating domestic sewage) has not 
submitted a notice of intent to be covered. A discharger (or treatment 
works treating domestic sewage) so notified may request an individual 
permit under paragraph (b)(3)(iii) of this section.
    (vii) A CAFO owner or operator may be authorized to discharge under 
a general permit only in accordance with the process described in Sec. 
122.23(h).
    (3) Requiring an individual permit. (i) The Director may require any 
discharger authorized by a general permit to apply for and obtain an 
individual NPDES permit. Any interested person may petition the Director 
to take action under this paragraph. Cases where an individual NPDES 
permit may be required include the following:
    (A) The discharger or ``treatment works treating domestic sewage'' 
is not in compliance with the conditions of the general NPDES permit;
    (B) A change has occurred in the availability of demonstrated 
technology or practices for the control or abatement of pollutants 
applicable to the point source or treatment works treating domestic 
sewage;
    (C) Effluent limitation guidelines are promulgated for point sources 
covered by the general NPDES permit;
    (D) A Water Quality Management plan containing requirements 
applicable to such point sources is approved;
    (E) Circumstances have changed since the time of the request to be 
covered so that the discharger is no longer appropriately controlled 
under the general permit, or either a temporary or permanent reduction 
or elimination of the authorized discharge is necessary;
    (F) Standards for sewage sludge use or disposal have been 
promulgated for the sludge use and disposal practice covered by the 
general NPDES permit; or
    (G) The discharge(s) is a significant contributor of pollutants. In 
making this determination, the Director may consider the following 
factors:
    (1) The location of the discharge with respect to waters of the 
United States;
    (2) The size of the discharge;
    (3) The quantity and nature of the pollutants discharged to waters 
of the United States; and
    (4) Other relevant factors;
    (ii) For EPA issued general permits only, the Regional Administrator 
may require any owner or operator authorized by a general permit to 
apply for an individual NPDES permit as provided in paragraph (b)(3)(i) 
of this section, only if the owner or operator has been notified in 
writing that a permit application is required. This notice shall include 
a brief statement of the reasons for this decision, an application form, 
a statement setting a time for the owner or operator to file the 
application, and a statement that on the effective date of the 
individual NPDES permit the general permit as it applies to the 
individual permittee shall automatically terminate. The Director may 
grant additional time upon request of the applicant.
    (iii) Any owner or operator authorized by a general permit may 
request to be excluded from the coverage of the general permit by 
applying for an individual permit. The owner or operator shall submit an 
application under Sec. 122.21, with reasons supporting the request, to 
the Director no later than 90 days after the publication by EPA of the 
general permit in the Federal Register or the publication by a State in 
accordance with applicable State law. The request shall be processed 
under part 124 or applicable State procedures. The request shall be 
granted by issuing of any individual permit if the reasons cited by the 
owner or operator are adequate to support the request.
    (iv) When an individual NPDES permit is issued to an owner or 
operator otherwise subject to a general NPDES permit, the applicability 
of the general

[[Page 243]]

permit to the individual NPDES permittee is automatically terminated on 
the effective date of the individual permit.
    (v) A source excluded from a general permit solely because it 
already has an individual permit may request that the individual permit 
be revoked, and that it be covered by the general permit. Upon 
revocation of the individual permit, the general permit shall apply to 
the source.
    (c) Offshore oil and gas facilities (Not applicable to State 
programs). (1) The Regional Administrator shall, except as provided 
below, issue general permits covering discharges from offshore oil and 
gas exploration and production facilities within the Region's 
jurisdiction. Where the offshore area includes areas, such as areas of 
biological concern, for which separate permit conditions are required, 
the Regional Administrator may issue separate general permits, 
individual permits, or both. The reason for separate general permits or 
individual permits shall be set forth in the appropriate fact sheets or 
statements of basis. Any statement of basis or fact sheet for a draft 
permit shall include the Regional Administrator's tentative 
determination as to whether the permit applies to ``new sources,'' ``new 
dischargers,'' or existing sources and the reasons for this 
determination, and the Regional Administrator's proposals as to areas of 
biological concern subject either to separate individual or general 
permits. For Federally leased lands, the general permit area should 
generally be no less extensive than the lease sale area defined by the 
Department of the Interior.
    (2) Any interested person, including any prospective permittee, may 
petition the Regional Administrator to issue a general permit. Unless 
the Regional Administrator determines under paragraph (c)(1) of this 
section that no general permit is appropriate, he shall promptly provide 
a project decision schedule covering the issuance of the general permit 
or permits for any lease sale area for which the Department of the 
Interior has published a draft environmental impact statement. The 
project decision schedule shall meet the requirements of Sec. 124.3(g), 
and shall include a schedule providing for the issuance of the final 
general permit or permits not later than the date of the final notice of 
sale projected by the Department of the Interior or six months after the 
date of the request, whichever is later. The Regional Administrator may, 
at his discretion, issue a project decision schedule for offshore oil 
and gas facilities in the territorial seas.
    (3) Nothing in this paragraph (c) shall affect the authority of the 
Regional Administrator to require an individual permit under Sec. 
122.28(b)(3)(i) (A) through (G).
    (d) Small municipal separate storm sewer systems (MS4s) (Applicable 
to State programs). For general permits issued under paragraph (b) of 
this section for small MS4s, the Director must establish the terms and 
conditions necessary to meet the requirements of Sec. 122.34 using one 
of the two permitting approaches in paragraph (d)(1) or (2) of this 
section. The Director must indicate in the permit or fact sheet which 
approach is being used.
    (1) Comprehensive general permit. The Director includes all required 
permit terms and conditions in the general permit; or
    (2) Two-step general permit. The Director includes required permit 
terms and conditions in the general permit applicable to all eligible 
small MS4s and, during the process of authorizing small MS4s to 
discharge, establishes additional terms and conditions not included in 
the general permit to satisfy one or more of the permit requirements in 
Sec. 122.34 for individual small MS4 operators.
    (i) The general permit must require that any small MS4 operator 
seeking authorization to discharge under the general permit submit a 
Notice of Intent (NOI) consistent with Sec. 122.33(b)(1)(ii).
    (ii) The Director must review the NOI submitted by the small MS4 
operator to determine whether the information in the NOI is complete and 
to establish the additional terms and conditions necessary to meet the 
requirements of Sec. 122.34. The Director may require the small MS4 
operator to submit additional information. If the Director makes a 
preliminary decision to authorize the small MS4 operator to discharge 
under the general permit, the

[[Page 244]]

Director must give the public notice of and opportunity to comment and 
request a public hearing on its proposed authorization and the NOI, the 
proposed additional terms and conditions, and the basis for these 
additional requirements. The public notice, the process for submitting 
public comments and hearing requests, and the hearing process if a 
request for a hearing is granted, must follow the procedures applicable 
to draft permits set forth in Sec. Sec. 124.10 through 124.13 
(excluding Sec. 124.10(c)(2)). The Director must respond to significant 
comments received during the comment period as provided in Sec. 124.17.
    (iii) Upon authorization for the MS4 to discharge under the general 
permit, the final additional terms and conditions applicable to the MS4 
operator become effective. The Director must notify the permittee and

Sec. 122.29  New sources and new dischargers.

    (a) Definitions. (1) New source and new discharger are defined in 
Sec. 122.2. [See Note 2.]
    (2) Source means any building, structure, facility, or installation 
from which there is or may be a discharge of pollutants.
    (3) Existing source means any source which is not a new source or a 
new discharger.
    (4) Site is defined in Sec. 122.2;
    (5) Facilities or equipment means buildings, structures, process or 
production equipment or machinery which form a permanent part of the new 
source and which will be used in its operation, if these facilities or 
equipment are of such value as to represent a substantial commitment to 
construct. It excludes facilities or equipment used in connection with 
feasibility, engineering, and design studies regarding the source or 
water pollution treatment for the source.
    (b) Criteria for new source determination. (1) Except as otherwise 
provided in an applicable new source performance standard, a source is a 
``new source'' if it meets the definition of ``new source'' in Sec. 
122.2, and
    (i) It is constructed at a site at which no other source is located; 
or
    (ii) It totally replaces the process or production equipment that 
causes the discharge of pollutants at an existing source; or
    (iii) Its processes are substantially independent of an existing 
source at the same site. In determining whether these processes are 
substantially independent, the Director shall consider such factors as 
the extent to which the new facility is integrated with the existing 
plant; and the extent to which the new facility is engaged in the same 
general type of activity as the existing source.
    (2) A source meeting the requirements of paragraphs (b)(1) (i), 
(ii), or (iii) of this section is a new source only if a new source 
performance standard is independently applicable to it. If there is no 
such independently applicable standard, the source is a new discharger. 
See Sec. 122.2.
    (3) Construction on a site at which an existing source is located 
results in a modification subject to Sec. 122.62 rather than a new 
source (or a new discharger) if the construction does not create a new 
building, structure, facility, or installation meeting the criteria of 
paragraph (b)(1) (ii) or (iii) of this section but otherwise alters, 
replaces, or adds to existing process or production equipment.
    (4) Construction of a new source as defined under Sec. 122.2 has 
commenced if the owner or operator has:
    (i) Begun, or caused to begin as part of a continuous on-site 
construction program:
    (A) Any placement, assembly, or installation of facilities or 
equipment; or

[[Page 245]]

    (B) Significant site preparation work including clearing, excavation 
or removal of existing buildings, structures, or facilities which is 
necessary for the placement, assembly, or installation of new source 
facilities or equipment; or
    (ii) Entered into a binding contractual obligation for the purchase 
of facilities or equipment which are intended to be used in its 
operation with a reasonable time. Options to purchase or contracts which 
can be terminated or modified without substantial loss, and contracts 
for feasibility engineering, and design studies do not constitute a 
contractual obligation under the paragraph.
    (c) Requirement for an environmental impact statement. (1) The 
issuance of an NPDES permit to new source:
    (i) By EPA may be a major Federal action significantly affecting the 
quality of the human environment within the meaning of the National 
Environmental Policy Act of 1969 (NEPA), 33 U.S.C. 4321 et seq. and is 
subject to the environmental review provisions of NEPA as set out in 40 
CFR part 6, subpart F. EPA will determine whether an Environmental 
Impact Statement (EIS) is required under Sec. 122.21(l) (special 
provisions for applications from new sources) and 40 CFR part 6, subpart 
F;
    (ii) By an NPDES approved State is not a Federal action and 
therefore does not require EPA to conduct an environmental review.
    (2) An EIS prepared under this paragraph shall include a 
recommendation either to issue or deny the permit.
    (i) If the recommendation is to deny the permit, the final EIS shall 
contain the reasons for the recommendation and list those measures, if 
any, which the applicant could take to cause the recommendation to be 
changed;
    (ii) If the recommendation is to issue the permit, the final EIS 
shall recommend the actions, if any, which the permittee should take to 
prevent or minimize any adverse environmental impacts;
    (3) The Regional Administrator, to the extent allowed by law, shall 
issue, condition (other than imposing effluent limitations), or deny the 
new source NPDES permit following a complete evaluation of any 
significant beneficial and adverse impacts of the proposed action and a 
review of the recommendations contained in the EIS or finding of no 
significant impact.
    (d) Effect of compliance with new source performance standards. (The 
provisions of this paragraph do not apply to existing sources which 
modify their pollution control facilities or construct new pollution 
control facilities and achieve performance standards, but which are 
neither new sources or new dischargers or otherwise do not meet the 
requirements of this paragraph.)
    (1) Except as provided in paragraph (d)(2) of this section, any new 
discharger, the construction of which commenced after October 18, 1972, 
or new source which meets the applicable promulgated new source 
performance standards before the commencement of discharge, may not be 
subject to any more stringent new source performance standards or to any 
more stringent technology-based standards under section 301(b)(2) of CWA 
for the soonest ending of the following periods:
    (i) Ten years from the date that construction is completed;
    (ii) Ten years from the date the source begins to discharge process 
or other nonconstruction related wastewater; or
    (iii) The period of depreciation or amortization of the facility for 
the purposes of section 167 or 169 (or both) of the Internal Revenue 
Code of 1954.
    (2) The protection from more stringent standards of performance 
afforded by paragraph (d)(1) of this section does not apply to:
    (i) Additional or more stringent permit conditions which are not 
technology based; for example, conditions based on water quality 
standards, or toxic effluent standards or prohibitions under section 
307(a) of CWA; or
    (ii) Additional permit conditions in accordance with Sec. 125.3 
controlling toxic pollutants or hazardous substances which are not 
controlled by new source performance standards. This includes permit 
conditions controlling pollutants other than those identified as toxic 
pollutants or hazardous substances when control of these pollutants has 
been specifically identified as the method to control the

[[Page 246]]

toxic pollutants or hazardous substances.
    (3) When an NPDES permit issued to a source with a ``protection 
period'' under paragraph (d)(1) of this section will expire on or after 
the expiration of the protection period, that permit shall require the 
owner or operator of the source to comply with the requirements of 
section 301 and any other then applicable requirements of CWA 
immediately upon the expiration of the protection period. No additional 
period for achieving compliance with these requirements may be allowed 
except when necessary to achieve compliance with requirements 
promulgated less than 3 years before the expiration of the protection 
period.
    (4) The owner or operator of a new source, a new discharger which 
commenced discharge after August 13, 1979, or a recommencing discharger 
shall install and have in operating condition, and shall ``start-up'' 
all pollution control equipment required to meet the conditions of its 
permits before beginning to discharge. Within the shortest feasible time 
(not to exceed 90 days), the owner or operator must meet all permit 
conditions. The requirements of this paragraph do not apply if the owner 
or operator is issued a permit containing a compliance schedule under 
Sec. 122.47(a)(2).
    (5) After the effective date of new source performance standards, it 
shall be unlawful for any owner or operator of any new source to operate 
the source in violation of those standards applicable to the source.

Sec. 122.30  What are the objectives of the storm water regulations
for small MS4s?

    (a) Sections 122.30 through 122.37 are written in a ``readable 
regulation'' format that includes both rule requirements and EPA 
guidance that is not legally binding. EPA has clearly distinguished its 
recommended guidance from the rule requirements by putting the guidance 
in a separate paragraph headed by the word ``guidance''.
    (b) Under the statutory mandate in section 402(p)(6) of the Clean 
Water Act, the purpose of this portion of the storm water program is to 
designate additional sources that need to be regulated to protect water 
quality and to establish a comprehensive storm water program to regulate 
these sources. (Because the storm water program is part of the National 
Pollutant Discharge Elimination System (NPDES) Program, you should also 
refer to Sec. 122.1 which addresses the broader purpose of the NPDES 
program.)
    (c) Storm water runoff continues to harm the nation's waters. Runoff 
from lands modified by human activities can harm surface water resources 
in several ways including by changing natural hydrologic patterns and by 
elevating pollutant concentrations and loadings. Storm water runoff may 
contain or mobilize high levels of contaminants, such as sediment, 
suspended solids, nutrients, heavy metals, pathogens, toxins, oxygen-
demanding substances, and floatables.
    (d) EPA strongly encourages partnerships and the watershed approach 
as the management framework for efficiently, effectively, and 
consistently protecting and restoring aquatic ecosystems and protecting 
public health.

[64 FR 68842, Dec. 8, 1999]



Sec. 122.31  As a Tribe, what is my role under the NPDES storm water
program?

    As a Tribe you may:
    (a) Be authorized to operate the NPDES program including the storm 
water program, after EPA determines that you are eligible for treatment 
in the same manner as a State under Sec. Sec. 123.31 through 123.34 of 
this chapter. (If you do not have an authorized NPDES program, EPA 
implements the program for discharges on your reservation as well as 
other Indian country, generally.);
    (b) Be classified as an owner of a regulated small MS4, as defined 
in Sec. 122.32. (Designation of your Tribe as an owner of a small MS4 
for purposes of this part is an approach that is consistent with EPA's 
1984 Indian Policy of operating on a government-to-government basis with 
EPA looking to Tribes as the lead governmental authorities to address

[[Page 247]]

environmental issues on their reservations as appropriate. If you 
operate a separate storm sewer system that meets the definition of a 
regulated small MS4, you are subject to the requirements under 
Sec. Sec. 122.33 through 122.35. If you are not designated as a 
regulated small MS4, you may ask EPA to designate you as such for the 
purposes of this part.); or
    (c) Be a discharger of storm water associated with industrial 
activity or small construction activity under Sec. Sec. 122.26(b)(14) 
or (b)(15), in which case you must meet the applicable requirements. 
Within Indian country, the NPDES permitting authority is generally EPA, 
unless you are authorized to administer the NPDES program.

[64 FR 68842, Dec. 8, 1999]



Sec. 122.32  As an operator of a small MS4, am I regulated under the
NPDES storm water program?

    (a) Unless you qualify for a waiver under paragraph (c) of this 
section, you are regulated if you operate a small MS4, including but not 
limited to systems operated by federal, State, Tribal, and local 
governments, including State departments of transportation; and:
    (1) Your small MS4 is located in an urbanized area as determined by 
the latest Decennial Census by the Bureau of the Census. (If your small 
MS4 is not located entirely within an urbanized area, only the portion 
that is within the urbanized area is regulated); or
    (2) You are designated by the NPDES permitting authority, including 
where the designation is pursuant to Sec. Sec. 123.35(b)(3) and (b)(4) 
of this chapter, or is based upon a petition under Sec. 122.26(f).
    (b) You may be the subject of a petition to the NPDES permitting 
authority to require an NPDES permit for your discharge of storm water. 
If the NPDES permitting authority determines that you need a permit, you 
are required to comply with Sec. Sec. 122.33 through 122.35.
    (c) The NPDES permitting authority may waive the requirements 
otherwise applicable to you if you meet the criteria of paragraph (d) or 
(e) of this section. If you receive a waiver under this section, you may 
subsequently be required to seek coverage under an NPDES permit in 
accordance with Sec. 122.33(a) if circumstances change. (See also Sec. 
123.35(b) of this chapter.)
    (d) The NPDES permitting authority may waive permit coverage if your 
MS4 serves a population of less than 1,000 within the urbanized area and 
you meet the following criteria:
    (1) Your system is not contributing substantially to the pollutant 
loadings of a physically interconnected MS4 that is regulated by the 
NPDES storm water program (see Sec. 123.35(b)(4) of this chapter); and
    (2) If you discharge any pollutant(s) that have been identified as a 
cause of impairment of any water body to which you discharge, storm 
water controls are not needed based on wasteload allocations that are 
part of an EPA approved or established ``total maximum daily load'' 
(TMDL) that addresses the pollutant(s) of concern.
    (e) The NPDES permitting authority may waive permit coverage if your 
MS4 serves a population under 10,000 and you meet the following 
criteria:
    (1) The permitting authority has evaluated all waters of the U.S., 
including small streams, tributaries, lakes, and ponds, that receive a 
discharge from your MS4;
    (2) For all such waters, the permitting authority has determined 
that storm water controls are not needed based on wasteload allocations 
that are part of an EPA approved or established TMDL that addresses the 
pollutant(s) of concern or, if a TMDL has not been developed or 
approved, an equivalent analysis that determines sources and allocations 
for the pollutant(s) of concern;
    (3) For the purpose of this paragraph (e), the pollutant(s) of 
concern include biochemical oxygen demand (BOD), sediment or a parameter 
that addresses sediment (such as total suspended solids, turbidity or 
siltation), pathogens, oil and grease, and any pollutant that has been 
identified as a cause of impairment of any water body that will receive 
a discharge from your MS4; and
    (4) The permitting authority has determined that future discharges 
from your MS4 do not have the potential to result in exceedances of 
water quality standards, including impairment of designated uses, or 
other significant

[[Page 248]]

water quality impacts, including habitat and biological impacts.

[64 FR 68842, Dec. 8, 1999]



Sec. 122.33  Requirements for obtaining permit coverage for regulated
small MS4s.

    (a) The operator of any regulated small MS4 under Sec. 122.32 must 
seek coverage under an NPDES permit issued by the applicable NPDES 
permitting authority. If the small MS4 is located in an NPDES authorized 
State, Tribe, or Territory, then that State, Tribe, or Territory is the 
NPDES permitting authority. Otherwise, the NPDES permitting authority is 
the EPA Regional Office for the Region where the small MS4 is located.
    (b) The operator of any regulated small MS4 must seek authorization 
to discharge under a general or individual NPDES permit, as follows:
    (1) General permit. (i) If seeking coverage under a general permit 
issued by the NPDES permitting authority in accordance with Sec. 
122.28(d)(1), the small MS4 operator must submit a Notice of Intent 
(NOI) to the NPDES permitting authority consistent with Sec. 
122.28(b)(2). The small MS4 operator may file its own NOI, or the small 
MS4 operator and other municipalities or governmental entities may 
jointly submit an NOI. If the small MS4 operator wants to share 
responsibilities for meeting the minimum measures with other 
municipalities or governmental entities, the small MS4 operator must 
submit an NOI that describes which minimum measures it will implement 
and identify the entities that will implement the other minimum measures 
within the area served by the MS4. The general permit will explain any 
other steps necessary to obtain permit authorization.
    (ii) If seeking coverage under a general permit issued by the NPDES 
permitting authority in accordance with Sec. 122.28(d)(2), the small 
MS4 operator must submit an NOI to the Director consisting of the 
minimum required information in Sec. 122.28(b)(2)(ii), and any other 
information the Director identifies as necessary to establish additional 
terms and conditions that satisfy the permit requirements of Sec. 
122.34, such as the information required under Sec. 122.33(b)(2)(i). 
The general permit will explain any other steps necessary to obtain 
permit authorization.
    (2) Individual permit. (i) If seeking authorization to discharge 
under an individual permit to implement a program under Sec. 122.34, 
the small MS4 operator must submit an application to the appropriate 
NPDES permitting authority that includes the information required under 
Sec. 122.21(f) and the following:
    (A) The best management practices (BMPs) that the small MS4 operator 
or another entity proposes to implement for each of the storm water 
minimum control measures described in Sec. 122.34(b)(1) through (6);
    (B) The proposed measurable goals for each of the BMPs including, as 
appropriate, the months and years in which the small MS4 operator 
proposes to undertake required actions, including interim milestones and 
the frequency of the action;
    (C) The person or persons responsible for implementing or 
coordinating the storm water management program;
    (D) An estimate of square mileage served by the small MS4;
    (E) Any additional information that the NPDES permitting authority 
requests; and
    (F) A storm sewer map that satisfies the requirement of Sec. 
122.34(b)(3)(i) satisfies the map requirement in Sec. 122.21(f)(7).
    (ii) If seeking authorization to discharge under an individual 
permit to implement a program that is different from the program under 
Sec. 122.34, the small MS4 operator must comply with the permit 
application requirements in Sec. 122.26(d). The small MS4 operator must 
submit both parts of the application requirements in Sec. 122.26(d)(1) 
and (2). The small MS4 operator must submit the application at least 180 
days before the expiration of the small MS4 operator's existing permit. 
Information required by Sec. 122.26(d)(1)(ii) and (d)(2) regarding its 
legal authority is not required, unless the small MS4 operator intends 
for the permit writer to take such information into account when 
developing other permit conditions.
    (iii) If allowed by your NPDES permitting authority, the small MS4 
operator and another regulated entity may jointly apply under either 
paragraph

[[Page 249]]

(b)(2)(i) or (ii) of this section to be co-permittees under an 
individual permit.
    (3) Co-permittee alternative. If the regulated small MS4 is in the 
same urbanized area as a medium or large MS4 with an NPDES storm water 
permit and that other MS4 is willing to have the small MS4 operator 
participate in its storm water program, the parties may jointly seek a 
modification of the other MS4 permit to include the small MS4 operator 
as a limited co-permittee. As a limited co-permittee, the small MS4 
operator will be responsible for compliance with the permit's conditions 
applicable to its jurisdiction. If the small MS4 operator chooses this 
option it must comply with the permit application requirements of Sec. 
122.26, rather than the requirements of Sec. 122.33(b)(2)(i). The small 
MS4 operator does not need to comply with the specific application 
requirements of Sec. 122.26(d)(1)(iii) and (iv) and (d)(2)(iii) 
(discharge characterization). The small MS4 operator may satisfy the 
requirements in Sec. 122.26 (d)(1)(v) and (d)(2)(iv) (identification of 
a management program) by referring to the other MS4's storm water 
management program.
    (4) Guidance for paragraph (b)(3) of this section. In referencing 
the other MS4 operator's storm water management program, the small MS4 
operator should briefly describe how the existing program will address 
discharges from the small MS4 or would need to be supplemented in order 
to adequately address the discharges. The small MS4 operator should also 
explain its role in coordinating storm water pollutant control 
activities in the MS4, and detail the resources available to the small 
MS4 operator to accomplish the program.
    (c) If the regulated small MS4 is designated under Sec. 
122.32(a)(2), the small MS4 operator must apply for coverage under an 
NPDES permit, or apply for a modification of an existing NPDES permit 
under paragraph (b)(3) of this section, within 180 days of notice of 
such designation, unless the NPDES permitting authority grants a later 
date.

[81 FR 89348, Dec. 9, 2016]



Sec. 122.34  Permit requirements for regulated small MS4 permits.

    (a) General requirements. For any permit issued to a regulated small 
MS4, the NPDES permitting authority must include permit terms and 
conditions to reduce the discharge of pollutants from the MS4 to the 
maximum extent practicable (MEP), to protect water quality, and to 
satisfy the appropriate water quality requirements of the Clean Water 
Act. Terms and conditions that satisfy the requirements of this section 
must be expressed in clear, specific, and measurable terms. Such terms 
and conditions may include narrative, numeric, or other types of 
requirements (e.g., implementation of specific tasks or best management 
practices (BMPs), BMP design requirements, performance requirements, 
adaptive management requirements, schedules for implementation and 
maintenance, and frequency of actions).
    (1) For permits providing coverage to any small MS4s for the first 
time, the NPDES permitting authority may specify a time period of up to 
5 years from the date of permit issuance for the permittee to fully 
comply with the conditions of the permit and to implement necessary 
BMPs.
    (2) For each successive permit, the NPDES permitting authority must 
include terms and conditions that meet the requirements of this section 
based on its evaluation of the current permit requirements, record of 
permittee compliance and program implementation progress, current water 
quality conditions, and other relevant information.
    (b) Minimum control measures. The permit must include requirements 
that ensure the permittee implements, or continues to implement, the 
minimum control measures in paragraphs (b)(1) through (6) of this 
section during the permit term. The permit must also require a written 
storm water management program document or documents that, at a minimum, 
describes in detail how the permittee intends to comply with the 
permit's requirements for each minimum control measure.
    (1) Public education and outreach on storm water impacts. (i) The 
permit must

[[Page 250]]

identify the minimum elements and require implementation of a public 
education program to distribute educational materials to the community 
or conduct equivalent outreach activities about the impacts of storm 
water discharges on water bodies and the steps that the public can take 
to reduce pollutants in storm water runoff.
    (ii) Guidance for NPDES permitting authorities and regulated small 
MS4s: The permittee may use storm water educational materials provided 
by the State, Tribe, EPA, environmental, public interest or trade 
organizations, or other MS4s. The public education program should inform 
individuals and households about the steps they can take to reduce storm 
water pollution, such as ensuring proper septic system maintenance, 
ensuring the proper use and disposal of landscape and garden chemicals 
including fertilizers and pesticides, protecting and restoring riparian 
vegetation, and properly disposing of used motor oil or household 
hazardous wastes. EPA recommends that the program inform individuals and 
groups how to become involved in local stream and beach restoration 
activities as well as activities that are coordinated by youth service 
and conservation corps or other citizen groups. EPA recommends that the 
permit require the permittee to tailor the public education program, 
using a mix of locally appropriate strategies, to target specific 
audiences and communities. Examples of strategies include distributing 
brochures or fact sheets, sponsoring speaking engagements before 
community groups, providing public service announcements, implementing 
educational programs targeted at school age children, and conducting 
community-based projects such as storm drain stenciling, and watershed 
and beach cleanups. In addition, EPA recommends that the permit require 
that some of the materials or outreach programs be directed toward 
targeted groups of commercial, industrial, and institutional entities 
likely to have significant storm water impacts. For example, providing 
information to restaurants on the impact of grease clogging storm drains 
and to garages on the impact of oil discharges. The permit should 
encourage the permittee to tailor the outreach program to address the 
viewpoints and concerns of all communities, particularly minority and 
disadvantaged communities, as well as any special concerns relating to 
children.
    (2) Public involvement/participation. (i) The permit must identify 
the minimum elements and require implementation of a public involvement/
participation program that complies with State, Tribal, and local public 
notice requirements.
    (ii) Guidance for NPDES permitting authorities and regulated small 
MS4s: EPA recommends that the permit include provisions addressing the 
need for the public to be included in developing, implementing, and 
reviewing the storm water management program and that the public 
participation process should make efforts to reach out and engage all 
economic and ethnic groups. Opportunities for members of the public to 
participate in program development and implementation include serving as 
citizen representatives on a local storm water management panel, 
attending public hearings, working as citizen volunteers to educate 
other individuals about the program, assisting in program coordination 
with other pre-existing programs, or participating in volunteer 
monitoring efforts. (Citizens should obtain approval where necessary for 
lawful access to monitoring sites.)
    (3) Illicit discharge detection and elimination. (i) The permit must 
identify the minimum elements and require the development, 
implementation, and enforcement of a program to detect and eliminate 
illicit discharges (as defined at Sec. 122.26(b)(2)) into the small 
MS4. At a minimum, the permit must require the permittee to:
    (A) Develop, if not already completed, a storm sewer system map, 
showing the location of all outfalls and the names and location of all 
waters of the United States that receive discharges from those outfalls;
    (B) To the extent allowable under State, Tribal or local law, 
effectively prohibit, through ordinance, or other regulatory mechanism, 
non-storm water discharges into the storm sewer system and implement 
appropriate enforcement procedures and actions;

[[Page 251]]

    (C) Develop and implement a plan to detect and address non-storm 
water discharges, including illegal dumping, to the system; and
    (D) Inform public employees, businesses, and the general public of 
hazards associated with illegal discharges and improper disposal of 
waste.
    (ii) The permit must also require the permittee to address the 
following categories of non-storm water discharges or flows (i.e., 
illicit discharges) only if the permittee identifies them as a 
significant contributor of pollutants to the small MS4: Water line 
flushing, landscape irrigation, diverted stream flows, rising ground 
waters, uncontaminated ground water infiltration (as defined at 40 CFR 
35.2005(b)(20)), uncontaminated pumped ground water, discharges from 
potable water sources, foundation drains, air conditioning condensation, 
irrigation water, springs, water from crawl space pumps, footing drains, 
lawn watering, individual residential car washing, flows from riparian 
habitats and wetlands, dechlorinated swimming pool discharges, and 
street wash water (discharges or flows from firefighting activities are 
excluded from the effective prohibition against non-storm water and need 
only be addressed where they are identified as significant sources of 
pollutants to waters of the United States).
    (iii) Guidance for NPDES permitting authorities and regulated small 
MS4s: EPA recommends that the permit require the plan to detect and 
address illicit discharges include the following four components: 
Procedures for locating priority areas likely to have illicit 
discharges; procedures for tracing the source of an illicit discharge; 
procedures for removing the source of the discharge; and procedures for 
program evaluation and assessment. EPA recommends that the permit 
require the permittee to visually screen outfalls during dry weather and 
conduct field tests of selected pollutants as part of the procedures for 
locating priority areas. Illicit discharge education actions may include 
storm drain stenciling, a program to promote, publicize, and facilitate 
public reporting of illicit connections or discharges, and distribution 
of outreach materials.
    (4) Construction site storm water runoff control. (i) The permit 
must identify the minimum elements and require the development, 
implementation, and enforcement of a program to reduce pollutants in any 
storm water runoff to the small MS4 from construction activities that 
result in a land disturbance of greater than or equal to one acre. 
Reduction of storm water discharges from construction activity 
disturbing less than one acre must be included in the program if that 
construction activity is part of a larger common plan of development or 
sale that would disturb one acre or more. If the Director waives 
requirements for storm water discharges associated with small 
construction activity in accordance with Sec. 122.26(b)(15)(i), the 
permittee is not required to develop, implement, and/or enforce a 
program to reduce pollutant discharges from such sites. At a minimum, 
the permit must require the permittee to develop and implement:
    (A) An ordinance or other regulatory mechanism to require erosion 
and sediment controls, as well as sanctions to ensure compliance, to the 
extent allowable under State, Tribal, or local law;
    (B) Requirements for construction site operators to implement 
appropriate erosion and sediment control best management practices;
    (C) Requirements for construction site operators to control waste 
such as discarded building materials, concrete truck washout, chemicals, 
litter, and sanitary waste at the construction site that may cause 
adverse impacts to water quality;
    (D) Procedures for site plan review which incorporate consideration 
of potential water quality impacts;
    (E) Procedures for receipt and consideration of information 
submitted by the public, and
    (F) Procedures for site inspection and enforcement of control 
measures.
    (ii) Guidance for NPDES permitting authorities and regulated small 
MS4s: Examples of sanctions to ensure compliance include non-monetary 
penalties, fines, bonding requirements and/or permit denials for non-
compliance. EPA recommends that the procedures for site plan review 
include the review of individual pre-construction site plans to ensure 
consistency with local

[[Page 252]]

sediment and erosion control requirements. Procedures for site 
inspections and enforcement of control measures could include steps to 
identify priority sites for inspection and enforcement based on the 
nature of the construction activity, topography, and the characteristics 
of soils and receiving water quality. EPA also recommends that the 
permit require the permittee to provide appropriate educational and 
training measures for construction site operators, and require storm 
water pollution prevention plans for construction sites within the MS4's 
jurisdiction that discharge into the system. See Sec. 122.44(s) (NPDES 
permitting authorities' option to incorporate qualifying State, Tribal 
and local erosion and sediment control programs into NPDES permits for 
storm water discharges from construction sites). Also see Sec. 
122.35(b) (The NPDES permitting authority may recognize that another 
government entity, including the NPDES permitting authority, may be 
responsible for implementing one or more of the minimum measures on the 
permittee's behalf).
    (5) Post-construction storm water management in new development and 
redevelopment. (i) The permit must identify the minimum elements and 
require the development, implementation, and enforcement of a program to 
address storm water runoff from new development and redevelopment 
projects that disturb greater than or equal to one acre, including 
projects less than one acre that are part of a larger common plan of 
development or sale, that discharge into the small MS4. The permit must 
ensure that controls are in place that would prevent or minimize water 
quality impacts. At a minimum, the permit must require the permittee to:
    (A) Develop and implement strategies which include a combination of 
structural and/or non-structural best management practices (BMPs) 
appropriate for the community;
    (B) Use an ordinance or other regulatory mechanism to address post-
construction runoff from new development and redevelopment projects to 
the extent allowable under State, Tribal or local law; and
    (C) Ensure adequate long-term operation and maintenance of BMPs.
    (ii) Guidance for NPDES permitting authorities and regulated small 
MS4s: If water quality impacts are considered from the beginning stages 
of a project, new development and potentially redevelopment provide more 
opportunities for water quality protection. EPA recommends that the 
permit ensure that BMPs included in the program: Be appropriate for the 
local community; minimize water quality impacts; and attempt to maintain 
pre-development runoff conditions. EPA encourages the permittee to 
participate in locally-based watershed planning efforts which attempt to 
involve a diverse group of stakeholders including interested citizens. 
When developing a program that is consistent with this measure's intent, 
EPA recommends that the permit require the permittee to adopt a planning 
process that identifies the municipality's program goals (e.g., minimize 
water quality impacts resulting from post-construction runoff from new 
development and redevelopment), implementation strategies (e.g., adopt a 
combination of structural and/or non-structural BMPs), operation and 
maintenance policies and procedures, and enforcement procedures. In 
developing the program, the permit should also require the permittee to 
assess existing ordinances, policies, programs and studies that address 
storm water runoff quality. In addition to assessing these existing 
documents and programs, the permit should require the permittee to 
provide opportunities to the public to participate in the development of 
the program. Non-structural BMPs are preventative actions that involve 
management and source controls such as: Policies and ordinances that 
provide requirements and standards to direct growth to identified areas, 
protect sensitive areas such as wetlands and riparian areas, maintain 
and/or increase open space (including a dedicated funding source for 
open space acquisition), provide buffers along sensitive water bodies, 
minimize impervious surfaces, and minimize disturbance of soils and 
vegetation; policies or ordinances that encourage infill development in 
higher density urban areas, and areas with existing infrastructure; 
education programs for developers and the public about project designs 
that minimize

[[Page 253]]

water quality impacts; and measures such as minimization of percent 
impervious area after development and minimization of directly connected 
impervious areas. Structural BMPs include: Storage practices such as wet 
ponds and extended-detention outlet structures; filtration practices 
such as grassed swales, sand filters and filter strips; and infiltration 
practices such as infiltration basins and infiltration trenches. EPA 
recommends that the permit ensure the appropriate implementation of the 
structural BMPs by considering some or all of the following: Pre-
construction review of BMP designs; inspections during construction to 
verify BMPs are built as designed; post-construction inspection and 
maintenance of BMPs; and penalty provisions for the noncompliance with 
design, construction or operation and maintenance. Storm water 
technologies are constantly being improved, and EPA recommends that the 
permit requirements be responsive to these changes, developments or 
improvements in control technologies.
    (6) Pollution prevention/good housekeeping for municipal operations. 
(i) The permit must identify the minimum elements and require the 
development and implementation of an operation and maintenance program 
that includes a training component and has the ultimate goal of 
preventing or reducing pollutant runoff from municipal operations. Using 
training materials that are available from EPA, the State, Tribe, or 
other organizations, the program must include employee training to 
prevent and reduce storm water pollution from activities such as park 
and open space maintenance, fleet and building maintenance, new 
construction and land disturbances, and storm water system maintenance.
    (ii) Guidance for NPDES permitting authorities and regulated small 
MS4s: EPA recommends that the permit address the following: Maintenance 
activities, maintenance schedules, and long-term inspection procedures 
for structural and non-structural storm water controls to reduce 
floatables and other pollutants discharged from the separate storm 
sewers; controls for reducing or eliminating the discharge of pollutants 
from streets, roads, highways, municipal parking lots, maintenance and 
storage yards, fleet or maintenance shops with outdoor storage areas, 
salt/sand storage locations and snow disposal areas operated by the 
permittee, and waste transfer stations; procedures for properly 
disposing of waste removed from the separate storm sewers and areas 
listed above (such as dredge spoil, accumulated sediments, floatables, 
and other debris); and ways to ensure that new flood management projects 
assess the impacts on water quality and examine existing projects for 
incorporating additional water quality protection devices or practices. 
Operation and maintenance should be an integral component of all storm 
water management programs. This measure is intended to improve the 
efficiency of these programs and require new programs where necessary. 
Properly developed and implemented operation and maintenance programs 
reduce the risk of water quality problems.
    (c) Other applicable requirements. As appropriate, the permit will 
include:
    (1) More stringent terms and conditions, including permit 
requirements that modify, or are in addition to, the minimum control 
measures based on an approved total maximum daily load (TMDL) or 
equivalent analysis, or where the Director determines such terms and 
conditions are needed to protect water quality.
    (2) Other applicable NPDES permit requirements, standards and 
conditions established in the individual or general permit, developed 
consistent with the provisions of Sec. Sec. 122.41 through 122.49.
    (d) Evaluation and assessment requirements--(1) Evaluation. The 
permit must require the permittee to evaluate compliance with the terms 
and conditions of the permit, including the effectiveness of the 
components of its storm water management program, and the status of 
achieving the measurable requirements in the permit.
    Note to paragraph (d)(1): The NPDES permitting authority may 
determine monitoring requirements for the permittee in accordance with 
State/Tribal monitoring plans appropriate to the watershed. 
Participation in a group monitoring program is encouraged.
    (2) Recordkeeping. The permit must require that the permittee keep 
records

[[Page 254]]

required by the NPDES permit for at least 3 years and submit such 
records to the NPDES permitting authority when specifically asked to do 
so. The permit must require the permittee to make records, including a 
written description of the storm water management program, available to 
the public at reasonable times during regular business hours (see Sec. 
122.7 for confidentiality provision). (The permittee may assess a 
reasonable charge for copying. The permit may allow the permittee to 
require a member of the public to provide advance notice.)
    (3) Reporting. Unless the permittee is relying on another entity to 
satisfy its NPDES permit obligations under Sec. 122.35(a), the 
permittee must submit annual reports to the NPDES permitting authority 
for its first permit term. For subsequent permit terms, the permittee 
must submit reports in year two and four unless the NPDES permitting 
authority requires more frequent reports. As of December 21, 2020 all 
reports submitted in compliance with this section must be submitted 
electronically by the owner, operator, or the duly authorized 
representative of the small MS4 to the NPDES permitting authority or 
initial recipient, as defined in 40 CFR 127.2(b), in compliance with 
this section and 40 CFR part 3 (including, in all cases, subpart D to 
part 3), Sec. 122.22, and 40 CFR part 127. Part 127 is not intended to 
undo existing requirements for electronic reporting. Prior to this date, 
and independent of part 127, the owner, operator, or the duly authorized 
representative of the small MS4 may be required to report electronically 
if specified by a particular permit or if required to do so by state 
law. The report must include:
    (i) The status of compliance with permit terms and conditions;
    (ii) Results of information collected and analyzed, including 
monitoring data, if any, during the reporting period;
    (iii) A summary of the storm water activities the permittee proposes 
to undertake to comply with the permit during the next reporting cycle;
    (iv) Any changes made during the reporting period to the permittee's 
storm water management program; and
    (v) Notice that the permittee is relying on another governmental 
entity to satisfy some of the permit obligations (if applicable), 
consistent with Sec. 122.35(a).
    (e) Qualifying local program. If an existing qualifying local 
program requires the permittee to implement one or more of the minimum 
control measures of paragraph (b) of this section, the NPDES permitting 
authority may include conditions in the NPDES permit that direct the 
permittee to follow that qualifying program's requirements rather than 
the requirements of paragraph (b). A qualifying local program is a 
local, State or Tribal municipal storm water management program that 
imposes, at a minimum, the relevant requirements of paragraph (b).

[81 FR 89349, Dec. 9, 2016]]



Sec. 122.35  May the operator of a regulated small MS4 share the
responsibility to implement the minimum control measures with 
other entities?

    (a) The permittee may rely on another entity to satisfy its NPDES 
permit obligations to implement a minimum control measure if:
    (1) The other entity, in fact, implements the control measure;
    (2) The particular control measure, or component thereof, is at 
least as stringent as the corresponding NPDES permit requirement; and
    (3) The other entity agrees to implement the control measure on the 
permittee's behalf. In the reports, the permittee must submit under 
Sec. 122.34(d)(3), the permittee must also specify that it is relying 
on another entity to satisfy some of the permit obligations. If the 
permittee is relying on another governmental entity regulated under 
section 122 to satisfy all of the permit obligations, including the 
obligation to file periodic reports required by Sec. 122.34(d)(3), the 
permittee must note that fact in its NOI, but the permittee is not 
required to file the periodic reports. The permittee remains responsible 
for compliance with the permit obligations if the other entity fails to 
implement the control measure (or component thereof). Therefore, EPA 
encourages the permittee to enter into a legally binding agreement with 
that

[[Page 255]]

entity if the permittee wants to minimize any uncertainty about 
compliance with the permit.
    (b) In some cases, the NPDES permitting authority may recognize, 
either in your individual NPDES permit or in an NPDES general permit, 
that another governmental entity is responsible under an NPDES permit 
for implementing one or more of the minimum control measures for your 
small MS4 or that the permitting authority itself is responsible. Where 
the permitting authority does so, you are not required to include such 
minimum control measure(s) in your storm water management program. (For 
example, if a State or Tribe is subject to an NPDES permit that requires 
it to administer a program to control construction site runoff at the 
State or Tribal level and that program satisfies all of the requirements 
of Sec. 122.34(b)(4), you could avoid responsibility for the 
construction measure, but would be responsible for the remaining minimum 
control measures.) Your permit may be reopened and modified to include 
the requirement to implement a minimum control measure if the entity 
fails to implement it.

Sec. 122.36  As an operator of a regulated small MS4, what happens
if I don't comply with the application or permit requirements in
Sec. Sec. 122.33 through 122.35?

    NPDES permits are federally enforceable. Violators may be subject to 
the enforcement actions and penalties described in Clean Water Act 
sections 309 (b), (c), and (g) and 505, or under applicable State, 
Tribal, or local law. Compliance with a permit issued pursuant to 
section 402 of the Clean Water Act is deemed compliance, for purposes of 
sections 309 and 505, with sections 301, 302, 306, 307, and 403, except 
any standard imposed under section 307 for toxic pollutants injurious to 
human health. If you are covered as a co-permittee under an individual 
permit or under a general permit by means of a joint Notice of Intent 
you remain subject to the enforcement actions and penalties for the 
failure to comply with the terms of the permit in your jurisdiction 
except as set forth in Sec. 122.35(b).

Sec. 122.37  Will the small MS4 storm water program regulations at
Sec. Sec. 122.32 through 122.36 and Sec. 123.35 of this chapter
change in the future?

    EPA will evaluate the small MS4 regulations at Sec. Sec. 122.32 
through 122.36 and Sec. 123.35 of this chapter after December 10, 2012 
and make any necessary revisions. (EPA intends to conduct an enhanced 
research effort and compile a comprehensive evaluation of the NPDES MS4 
storm water program. EPA will re-evaluate the regulations based on data 
from the NPDES MS4 storm water program, from research on receiving water 
impacts from storm water, and the effectiveness of best management 
practices (BMPs), as well as other relevant information sources.)

[64 FR 68847, Dec. 8, 1999]



                       Subpart C_Permit Conditions



Sec. 122.41  Conditions applicable to all permits (applicable to
State programs, see Sec. 123.25).

    The following conditions apply to all NPDES permits. Additional 
conditions applicable to NPDES permits are in Sec. 122.42. All 
conditions applicable to NPDES permits shall be incorporated into the 
permits either expressly or by reference. If incorporated by reference, 
a specific citation to these regulations (or the corresponding approved 
State regulations) must be given in the permit.
    (a) Duty to comply. The permittee must comply with all conditions of 
this permit. Any permit noncompliance constitutes a violation of the 
Clean Water Act and is grounds for enforcement action; for permit 
termination, revocation and reissuance, or modification; or denial of a 
permit renewal application.
    (1) The permittee shall comply with effluent standards or 
prohibitions established under section 307(a) of the Clean Water Act for 
toxic pollutants and with standards for sewage sludge use or disposal 
established under section 405(d) of the CWA within the time

[[Page 256]]

provided in the regulations that establish these standards or 
prohibitions or standards for sewage sludge use or disposal, even if the 
permit has not yet been modified to incorporate the requirement.
    (2) The Clean Water Act provides that any person who violates 
section 301, 302, 306, 307, 308, 318 or 405 of the Act, or any permit 
condition or limitation implementing any such sections in a permit 
issued under section 402, or any requirement imposed in a pretreatment 
program approved under sections 402(a)(3) or 402(b)(8) of the Act, is 
subject to a civil penalty not to exceed $25,000 per day for each 
violation. The Clean Water Act provides that any person who negligently 
violates sections 301, 302, 306, 307, 308, 318, or 405 of the Act, or 
any condition or limitation implementing any of such sections in a 
permit issued under section 402 of the Act, or any requirement imposed 
in a pretreatment program approved under section 402(a)(3) or 402(b)(8) 
of the Act, is subject to criminal penalties of $2,500 to $25,000 per 
day of violation, or imprisonment of not more than 1 year, or both. In 
the case of a second or subsequent conviction for a negligent violation, 
a person shall be subject to criminal penalties of not more than $50,000 
per day of violation, or by imprisonment of not more than 2 years, or 
both. Any person who knowingly violates such sections, or such 
conditions or limitations is subject to criminal penalties of $5,000 to 
$50,000 per day of violation, or imprisonment for not more than 3 years, 
or both. In the case of a second or subsequent conviction for a knowing 
violation, a person shall be subject to criminal penalties of not more 
than $100,000 per day of violation, or imprisonment of not more than 6 
years, or both. Any person who knowingly violates section 301, 302, 303, 
306, 307, 308, 318 or 405 of the Act, or any permit condition or 
limitation implementing any of such sections in a permit issued under 
section 402 of the Act, and who knows at that time that he thereby 
places another person in imminent danger of death or serious bodily 
injury, shall, upon conviction, be subject to a fine of not more than 
$250,000 or imprisonment of not more than 15 years, or both. In the case 
of a second or subsequent conviction for a knowing endangerment 
violation, a person shall be subject to a fine of not more than $500,000 
or by imprisonment of not more than 30 years, or both. An organization, 
as defined in section 309(c)(3)(B)(iii) of the CWA, shall, upon 
conviction of violating the imminent danger provision, be subject to a 
fine of not more than $1,000,000 and can be fined up to $2,000,000 for 
second or subsequent convictions.
    (3) Any person may be assessed an administrative penalty by the 
Administrator for violating section 301, 302, 306, 307, 308, 318 or 405 
of this Act, or any permit condition or limitation implementing any of 
such sections in a permit issued under section 402 of this Act. 
Administrative penalties for Class I violations are not to exceed 
$10,000 per violation, with the maximum amount of any Class I penalty 
assessed not to exceed $25,000. Penalties for Class II violations are 
not to exceed $10,000 per day for each day during which the violation 
continues, with the maximum amount of any Class II penalty not to exceed 
$125,000.
    (b) Duty to reapply. If the permittee wishes to continue an activity 
regulated by this permit after the expiration date of this permit, the 
permittee must apply for and obtain a new permit.
    (c) Need to halt or reduce activity not a defense. It shall not be a 
defense for a permittee in an enforcement action that it would have been 
necessary to halt or reduce the permitted activity in order to maintain 
compliance with the conditions of this permit.
    (d) Duty to mitigate. The permittee shall take all reasonable steps 
to minimize or prevent any discharge or sludge use or disposal in 
violation of this permit which has a reasonable likelihood of adversely 
affecting human health or the environment.
    (e) Proper operation and maintenance. The permittee shall at all 
times properly operate and maintain all facilities and systems of 
treatment and control (and related appurtenances) which are installed or 
used by the permittee to achieve compliance with the conditions of this 
permit. Proper operation and maintenance also includes adequate 
laboratory controls and appropriate

[[Page 257]]

quality assurance procedures. This provision requires the operation of 
back-up or auxiliary facilities or similar systems which are installed 
by a permittee only when the operation is necessary to achieve 
compliance with the conditions of the permit.
    (f) Permit actions. This permit may be modified, revoked and 
reissued, or terminated for cause. The filing of a request by the 
permittee for a permit modification, revocation and reissuance, or 
termination, or a notification of planned changes or anticipated 
noncompliance does not stay any permit condition.
    (g) Property rights. This permit does not convey any property rights 
of any sort, or any exclusive privilege.
    (h) Duty to provide information. The permittee shall furnish to the 
Director, within a reasonable time, any information which the Director 
may request to determine whether cause exists for modifying, revoking 
and reissuing, or terminating this permit or to determine compliance 
with this permit. The permittee shall also furnish to the Director upon 
request, copies of records required to be kept by this permit.
    (i) Inspection and entry. The permittee shall allow the Director, or 
an authorized representative (including an authorized contractor acting 
as a representative of the Administrator), upon presentation of 
credentials and other documents as may be required by law, to:
    (1) Enter upon the permittee's premises where a regulated facility 
or activity is located or conducted, or where records must be kept under 
the conditions of this permit;
    (2) Have access to and copy, at reasonable times, any records that 
must be kept under the conditions of this permit;
    (3) Inspect at reasonable times any facilities, equipment (including 
monitoring and control equipment), practices, or operations regulated or 
required under this permit; and
    (4) Sample or monitor at reasonable times, for the purposes of 
assuring permit compliance or as otherwise authorized by the Clean Water 
Act, any substances or parameters at any location.
    (j) Monitoring and records. (1) Samples and measurements taken for 
the purpose of monitoring shall be representative of the monitored 
activity.
    (2) Except for records of monitoring information required by this 
permit related to the permittee's sewage sludge use and disposal 
activities, which shall be retained for a period of at least five years 
(or longer as required by 40 CFR part 503), the permittee shall retain 
records of all monitoring information, including all calibration and 
maintenance records and all original strip chart recordings for 
continuous monitoring instrumentation, copies of all reports required by 
this permit, and records of all data used to complete the application 
for this permit, for a period of at least 3 years from the date of the 
sample, measurement, report or application. This period may be extended 
by request of the Director at any time.
    (3) Records of monitoring information shall include:
    (i) The date, exact place, and time of sampling or measurements;
    (ii) The individual(s) who performed the sampling or measurements;
    (iii) The date(s) analyses were performed;
    (iv) The individual(s) who performed the analyses;
    (v) The analytical techniques or methods used; and
    (vi) The results of such analyses.
    (4) Monitoring must be conducted according to test procedures 
approved under 40 CFR Part 136 unless another method is required under 
40 CFR subchapters N or O.
    (5) The Clean Water Act provides that any person who falsifies, 
tampers with, or knowingly renders inaccurate any monitoring device or 
method required to be maintained under this permit shall, upon 
conviction, be punished by a fine of not more than $10,000, or by 
imprisonment for not more than 2 years, or both. If a conviction of a 
person is for a violation committed after a first conviction of such 
person under this paragraph, punishment is a fine of not more than 
$20,000 per day of violation, or by imprisonment of not more than 4 
years, or both.
    (k) Signatory requirement. (1) All applications, reports, or 
information submitted to the Director shall be signed and certified. 
(See Sec. 122.22)

[[Page 258]]

    (2) The CWA provides that any person who knowingly makes any false 
statement, representation, or certification in any record or other 
document submitted or required to be maintained under this permit, 
including monitoring reports or reports of compliance or non-compliance 
shall, upon conviction, be punished by a fine of not more than $10,000 
per violation, or by imprisonment for not more than 6 months per 
violation, or by both.
    (l) Reporting requirements--(1) Planned changes. The permittee shall 
give notice to the Director as soon as possible of any planned physical 
alterations or additions to the permitted facility. Notice is required 
only when:
    (i) The alteration or addition to a permitted facility may meet one 
of the criteria for determining whether a facility is a new source in 
Sec. 122.29(b); or
    (ii) The alteration or addition could significantly change the 
nature or increase the quantity of pollutants discharged. This 
notification applies to pollutants which are subject neither to effluent 
limitations in the permit, nor to notification requirements under Sec. 
122.42(a)(1).
    (iii) The alteration or addition results in a significant change in 
the permittee's sludge use or disposal practices, and such alteration, 
addition, or change may justify the application of permit conditions 
that are different from or absent in the existing permit, including 
notification of additional use or disposal sites not reported during the 
permit application process or not reported pursuant to an approved land 
application plan;
    (2) Anticipated noncompliance. The permittee shall give advance 
notice to the Director of any planned changes in the permitted facility 
or activity which may result in noncompliance with permit requirements.
    (3) Transfers. This permit is not transferable to any person except 
after notice to the Director. The Director may require modification or 
revocation and reissuance of the permit to change the name of the 
permittee and incorporate such other requirements as may be necessary 
under the Clean Water Act. (See Sec. 122.61; in some cases, 
modification or revocation and reissuance is mandatory.)
    (4) Monitoring reports. Monitoring results shall be reported at the 
intervals specified elsewhere in this permit.
    (i) Monitoring results must be reported on a Discharge Monitoring 
Report (DMR) or forms provided or specified by the Director for 
reporting results of monitoring of sludge use or disposal practices. As 
of December 21, 2016 all reports and forms submitted in compliance with 
this section must be submitted electronically by the permittee to the 
Director or initial recipient, as defined in 40 CFR 127.2(b), in 
compliance with this section and 40 CFR part 3 (including, in all cases, 
subpart D to part 3), Sec. 122.22, and 40 CFR part 127. Part 127 is not 
intended to undo existing requirements for electronic reporting. Prior 
to this date, and independent of part 127, permittees may be required to 
report electronically if specified by a particular permit or if required 
to do so by state law.
    (ii) If the permittee monitors any pollutant more frequently than 
required by the permit using test procedures approved under 40 CFR Part 
136, or another method required for an industry-specific waste stream 
under 40 CFR subchapters N or O, the results of such monitoring shall be 
included in the calculation and reporting of the data submitted in the 
DMR or sludge reporting form specified by the Director.
    (iii) Calculations for all limitations which require averaging of 
measurements shall utilize an arithmetic mean unless otherwise specified 
by the Director in the permit.
    (5) Compliance schedules. Reports of compliance or noncompliance 
with, or any progress reports on, interim and final requirements 
contained in any compliance schedule of this permit shall be submitted 
no later than 14 days following each schedule date.
    (6) Twenty-four hour reporting.
    (i) The permittee shall report any noncompliance which may endanger 
health or the environment. Any information shall be provided orally 
within 24 hours from the time the permittee becomes aware of the 
circumstances. A report shall also be provided within 5 days of the time 
the permittee becomes aware of the circumstances. The report

[[Page 259]]

shall contain a description of the noncompliance and its cause; the 
period of noncompliance, including exact dates and times), and if the 
noncompliance has not been corrected, the anticipated time it is 
expected to continue; and steps taken or planned to reduce, eliminate, 
and prevent reoccurrence of the noncompliance. For noncompliance events 
related to combined sewer overflows, sanitary sewer overflows, or bypass 
events, these reports must include the data described above (with the 
exception of time of discovery) as well as the type of event (combined 
sewer overflows, sanitary sewer overflows, or bypass events), type of 
sewer overflow structure (e.g., manhole, combine sewer overflow 
outfall), discharge volumes untreated by the treatment works treating 
domestic sewage, types of human health and environmental impacts of the 
sewer overflow event, and whether the noncompliance was related to wet 
weather. As of December 21, 2020 all reports related to combined sewer 
overflows, sanitary sewer overflows, or bypass events submitted in 
compliance with this section must be submitted electronically by the 
permittee to the Director or initial recipient, as defined in 40 CFR 
127.2(b), in compliance with this section and 40 CFR part 3 (including, 
in all cases, subpart D to part 3), Sec. 122.22, and 40 CFR part 127. 
Part 127 is not intended to undo existing requirements for electronic 
reporting. Prior to this date, and independent of part 127, permittees 
may be required to electronically submit reports related to combined 
sewer overflows, sanitary sewer overflows, or bypass events under this 
section by a particular permit or if required to do so by state law. The 
Director may also require permittees to electronically submit reports 
not related to combined sewer overflows, sanitary sewer overflows, or 
bypass events under this section.
    (ii) The following shall be included as information which must be 
reported within 24 hours under this paragraph.
    (A) Any unanticipated bypass which exceeds any effluent limitation 
in the permit. (See Sec. 122.41(g).
    (B) Any upset which exceeds any effluent limitation in the permit.
    (C) Violation of a maximum daily discharge limitation for any of the 
pollutants listed by the Director in the permit to be reported within 24 
hours. (See Sec. 122.44(g).)
    (iii) The Director may waive the written report on a case-by-case 
basis for reports under paragraph (l)(6)(ii) of this section if the oral 
report has been received within 24 hours.
    (7) Other noncompliance. The permittee shall report all instances of 
noncompliance not reported under paragraphs (l)(4), (5), and (6) of this 
section, at the time monitoring reports are submitted. The reports shall 
contain the information listed in paragraph (l)(6). For noncompliance 
events related to combined sewer overflows, sanitary sewer overflows, or 
bypass events, these reports shall contain the information described in 
paragraph (l)(6) and the applicable required data in appendix A to 40 
CFR part 127. As of December 21, 2020 all reports related to combined 
sewer overflows, sanitary sewer overflows, or bypass events submitted in 
compliance with this section must be submitted electronically by the 
permittee to the Director or initial recipient, as defined in 40 CFR 
127.2(b), in compliance with this section and 40 CFR part 3 (including, 
in all cases, subpart D to part 3), Sec. 122.22, and 40 CFR part 127. 
Part 127 is not intended to undo existing requirements for electronic 
reporting. Prior to this date, and independent of part 127, permittees 
may be required to electronically submit reports related to combined 
sewer overflows, sanitary sewer overflows, or bypass events under this 
section by a particular permit or if required to do so by state law. The 
Director may also require permittees to electronically submit reports 
not related to combined sewer overflows, sanitary sewer overflows, or 
bypass events under this section.
    (8) Other information. Where the permittee becomes aware that it 
failed to submit any relevant facts in a permit application, or 
submitted incorrect information in a permit application or in any report 
to the Director, it shall promptly submit such facts or information.
    (9) Identification of the initial recipient for NPDES electronic 
reporting data. The owner, operator, or the duly authorized 
representative of an NPDES-regulated

[[Page 260]]

entity is required to electronically submit the required NPDES 
information (as specified in appendix A to 40 CFR part 127) to the 
appropriate initial recipient, as determined by EPA, and as defined in 
Sec. 127.2(b) of this chapter. EPA will identify and publish the list 
of initial recipients on its Web site and in the Federal Register, by 
state and by NPDES data group [see Sec. 127.2(c) of this chapter]. EPA 
will update and maintain this listing.
    (m) Bypass--(1) Definitions. (i) Bypass means the intentional 
diversion of waste streams from any portion of a treatment facility.
    (ii) Severe property damage means substantial physical damage to 
property, damage to the treatment facilities which causes them to become 
inoperable, or substantial and permanent loss of natural resources which 
can reasonably be expected to occur in the absence of a bypass. Severe 
property damage does not mean economic loss caused by delays in 
production.
    (2) Bypass not exceeding limitations. The permittee may allow any 
bypass to occur which does not cause effluent limitations to be 
exceeded, but only if it also is for essential maintenance to assure 
efficient operation. These bypasses are not subject to the provisions of 
paragraphs (m)(3) and (m)(4) of this section.
    (3) Notice--(i) Anticipated bypass. If the permittee knows in 
advance of the need for a bypass, it shall submit prior notice, if 
possible at least ten days before the date of the bypass. As of December 
21, 2020 all notices submitted in compliance with this section must be 
submitted electronically by the permittee to the Director or initial 
recipient, as defined in 40 CFR 127.2(b), in compliance with this 
section and 40 CFR part 3 (including, in all cases, subpart D to part 
3), Sec. 122.22, and 40 CFR part 127. Part 127 is not intended to undo 
existing requirements for electronic reporting. Prior to this date, and 
independent of part 127, permittees may be required to report 
electronically if specified by a particular permit or if required to do 
so by state law.
    (ii) Unanticipated bypass. The permittee shall submit notice of an 
unanticipated bypass as required in paragraph (l)(6) of this section 
(24-hour notice). As of December 21, 2020 all notices submitted in 
compliance with this section must be submitted electronically by the 
permittee to the Director or initial recipient, as defined in 40 CFR 
127.2(b), in compliance with this section and 40 CFR part 3 (including, 
in all cases, subpart D to part 3), Sec. 122.22, and 40 CFR part 127. 
Part 127 is not intended to undo existing requirements for electronic 
reporting. Prior to this date, and independent of part 127, permittees 
may be required to report electronically if specified by a particular 
permit or if required to do so by state law.
    (4) Prohibition of bypass. (i) Bypass is prohibited, and the 
Director may take enforcement action against a permittee for bypass, 
unless:
    (A) Bypass was unavoidable to prevent loss of life, personal injury, 
or severe property damage;
    (B) There were no feasible alternatives to the bypass, such as the 
use of auxiliary treatment facilities, retention of untreated wastes, or 
maintenance during normal periods of equipment downtime. This condition 
is not satisfied if adequate back-up equipment should have been 
installed in the exercise of reasonable engineering judgment to prevent 
a bypass which occurred during normal periods of equipment downtime or 
preventive maintenance; and
    (C) The permittee submitted notices as required under paragraph 
(m)(3) of this section.
    (ii) The Director may approve an anticipated bypass, after 
considering its adverse effects, if the Director determines that it will 
meet the three conditions listed above in paragraph (m)(4)(i) of this 
section.
    (n) Upset--(1) Definition. Upset means an exceptional incident in 
which there is unintentional and temporary noncompliance with technology 
based permit effluent limitations because of factors beyond the 
reasonable control of the permittee. An upset does not include 
noncompliance to the extent caused by operational error, improperly 
designed treatment facilities, inadequate treatment facilities, lack of 
preventive maintenance, or careless or improper operation.

[[Page 261]]

    (2) Effect of an upset. An upset constitutes an affirmative defense 
to an action brought for noncompliance with such technology based permit 
effluent limitations if the requirements of paragraph (n)(3) of this 
section are met. No determination made during administrative review of 
claims that noncompliance was caused by upset, and before an action for 
noncompliance, is final administrative action subject to judicial 
review.
    (3) Conditions necessary for a demonstration of upset. A permittee 
who wishes to establish the affirmative defense of upset shall 
demonstrate, through properly signed, contemporaneous operating logs, or 
other relevant evidence that:
    (i) An upset occurred and that the permittee can identify the 
cause(s) of the upset;
    (ii) The permitted facility was at the time being properly operated; 
and
    (iii) The permittee submitted notice of the upset as required in 
paragraph (1)(6)(ii)(B) of this section (24 hour notice).
    (iv) The permittee complied with any remedial measures required 
under paragraph (d) of this section.
    (4) Burden of proof. In any enforcement proceeding the permittee 
seeking to establish the occurrence of an upset has the burden of proof.

122.41, apply to all NPDES permits within the categories specified 
below:
    (a) Existing manufacturing, commercial, mining, and silvicultural 
dischargers. In addition to the reporting requirements under Sec. 
122.41(1), all existing manufacturing, commercial, mining, and 
silvicultural dischargers must notify the Director as soon as they know 
or have reason to believe:
    (1) That any activity has occurred or will occur which would result 
in the discharge, on a routine or frequent basis, of any toxic pollutant 
which is not limited in the permit, if that discharge will exceed the 
highest of the following ``notification levels'':
    (i) One hundred micrograms per liter (100 [micro] g/l);
    (ii) Two hundred micrograms per liter (200 [micro] g/l) for acrolein 
and acrylonitrile; five hundred micrograms per liter (500 [micro] g/l) 
for 2,4-dinitrophenol and for 2-methyl-4,6-dinitrophenol; and one 
milligram per liter (1 mg/l) for antimony;
    (iii) Five (5) times the maximum concentration value reported for 
that pollutant in the permit application in accordance with Sec. 
122.21(g)(7); or
    (iv) The level established by the Director in accordance with Sec. 
122.44(f).
    (2) That any activity has occurred or will occur which would result 
in any discharge, on a non-routine or infrequent basis, of a toxic 
pollutant which is not limited in the permit, if that discharge will 
exceed the highest of the following ``notification levels'':
    (i) Five hundred micrograms per liter (500 [micro] g/l);
    (ii) One milligram per liter (1 mg/l) for antimony;
    (iii) Ten (10) times the maximum concentration value reported for 
that pollutant in the permit application in accordance with Sec.

    (iv) The level established by the Director in accordance with Sec. 
122.44(f).
    (b) Publicly owned treatment works. All POTWs must provide adequate 
notice to the Director of the following:
    (1) Any new introduction of pollutants into the POTW from an 
indirect discharger which would be subject to section 301 or 306 of CWA 
if it were directly discharging those pollutants; and
    (2) Any substantial change in the volume or character of pollutants 
being introduced into that POTW by a source introducing pollutants into 
the POTW at the time of issuance of the permit.
    (3) For purposes of this paragraph, adequate notice shall include 
information on (i) the quality and quantity of

[[Page 262]]

effluent introduced into the POTW, and (ii) any anticipated impact of 
the change on the quantity or quality of effluent to be discharged from 
the POTW.
    (c) Municipal separate storm sewer systems. The operator of a large 
or medium municipal separate storm sewer system or a municipal separate 
storm sewer that has been designated by the Director under Sec. 
122.26(a)(1)(v) must submit an annual report by the anniversary of the 
date of the issuance of the permit for such system. As of December 21, 
2020 all reports submitted in compliance with this section must be 
submitted electronically by the owner, operator, or the duly authorized 
representative of the MS4 to the Director or initial recipient, as 
defined in 40 CFR 127.2(b), in compliance with this section and 40 CFR 
part 3 (including, in all cases, subpart D to part 3), Sec. 122.22, and 
40 CFR part 127. Part 127 is not intended to undo existing requirements 
for electronic reporting. Prior to this date, and independent of part 
127, the owner, operator, or the duly authorized representative of the 
MS4 may be required to report electronically if specified by a 
particular permit or if required to do so by state law. The report shall 
include:
    (1) The status of implementing the components of the storm water 
management program that are established as permit conditions;
    (2) Proposed changes to the storm water management programs that are 
established as permit condition. Such proposed changes shall be 
consistent with Sec. 122.26(d)(2)(iii) of this part; and
    (3) Revisions, if necessary, to the assessment of controls and the 
fiscal analysis reported in the permit application under Sec. 
122.26(d)(2)(iv) and (d)(2)(v) of this part;
    (4) A summary of data, including monitoring data, that is 
accumulated throughout the reporting year;
    (5) Annual expenditures and budget for year following each annual 
report;
    (6) A summary describing the number and nature of enforcement 
actions, inspections, and public education programs;
    (7) Identification of water quality improvements or degradation;
    (d) Storm water discharges. The initial permits for discharges 
composed entirely of storm water issued pursuant to Sec. 122.26(e)(7) 
of this part shall require compliance with the conditions of the permit 
as expeditiously as practicable, but in no event later than three years 
after the date of issuance of the permit.
    (e) Concentrated animal feeding operations (CAFOs). Any permit 
issued to a CAFO must include the requirements in paragraphs (e)(1) 
through (e)(6) of this section.
    (1) Requirement to implement a nutrient management plan. Any permit 
issued to a CAFO must include a requirement to implement a nutrient 
management plan that, at a minimum, contains best management practices 
necessary to meet the requirements of this paragraph and applicable 
effluent limitations and standards, including those specified in 40 CFR 
part 412. The nutrient management plan must, to the extent applicable:
    (i) Ensure adequate storage of manure, litter, and process 
wastewater, including procedures to ensure proper operation and 
maintenance of the storage facilities;
    (ii) Ensure proper management of mortalities (i.e., dead animals) to 
ensure that they are not disposed of in a liquid manure, storm water, or 
process wastewater storage or treatment system that is not specifically 
designed to treat animal mortalities;
    (iii) Ensure that clean water is diverted, as appropriate, from the 
production area;
    (iv) Prevent direct contact of confined animals with waters of the 
United States;
    (v) Ensure that chemicals and other contaminants handled on-site are 
not disposed of in any manure, litter, process wastewater, or storm 
water storage or treatment system unless specifically designed to treat 
such chemicals and other contaminants;
    (vi) Identify appropriate site specific conservation practices to be 
implemented, including as appropriate buffers or equivalent practices, 
to control runoff of pollutants to waters of the United States;

[[Page 263]]

    (vii) Identify protocols for appropriate testing of manure, litter, 
process wastewater, and soil;
    (viii) Establish protocols to land apply manure, litter or process 
wastewater in accordance with site specific nutrient management 
practices that ensure appropriate agricultural utilization of the 
nutrients in the manure, litter or process wastewater; and
    (ix) Identify specific records that will be maintained to document 
the implementation and management of the minimum elements described in 
paragraphs (e)(1)(i) through (e)(1)(viii) of this section.
    (2) Recordkeeping requirements. (i) The permittee must create, 
maintain for five years, and make available to the Director, upon 
request, the following records:
    (A) All applicable records identified pursuant paragraph (e)(1)(ix) 
of this section;
    (B) In addition, all CAFOs subject to 40 CFR part 412 must comply 
with record keeping requirements as specified in Sec. 412.37(b) and (c) 
and Sec. 412.47(b) and (c).
    (ii) A copy of the CAFO's site-specific nutrient management plan 
must be maintained on site and made available to the Director upon 
request.
    (3) Requirements relating to transfer of manure or process 
wastewater to other persons. Prior to transferring manure, litter or 
process wastewater to other persons, Large CAFOs must provide the 
recipient of the manure, litter or process wastewater with the most 
current nutrient analysis. The analysis provided must be consistent with 
the requirements of 40 CFR part 412. Large CAFOs must retain for five 
years records of the date, recipient name and address, and approximate 
amount of manure, litter or process wastewater transferred to another 
person.
    (4) Annual reporting requirements for CAFOs. The permittee must 
submit an annual report to the Director. As of December 21, 2020 all 
annual reports submitted in compliance with this section must be 
submitted electronically by the permittee to the Director or initial 
recipient, as defined in 40 CFR 127.2(b), in compliance with this 
section and 40 CFR part 3 (including, in all cases, subpart D to part 
3), Sec. 122.22, and 40 CFR part 127. Part 127 is not intended to undo 
existing requirements for electronic reporting. Prior to this date, and 
independent of part 127, the permittee may be required to report 
electronically if specified by a particular permit or if required to do 
so by state law. The annual report must include:
    (i) The number and type of animals, whether in open confinement or 
housed under roof (beef cattle, broilers, layers, swine weighing 55 
pounds or more, swine weighing less than 55 pounds, mature dairy cows, 
dairy heifers, veal calves, sheep and lambs, horses, ducks, turkeys, 
other);
    (ii) Estimated amount of total manure, litter and process wastewater 
generated by the CAFO in the previous 12 months (tons/gallons);
    (iii) Estimated amount of total manure, litter and process 
wastewater transferred to other person by the CAFO in the previous 12 
months (tons/gallons);
    (iv) Total number of acres for land application covered by the 
nutrient management plan developed in accordance with paragraph (e)(1) 
of this section;
    (v) Total number of acres under control of the CAFO that were used 
for land application of manure, litter and process wastewater in the 
previous 12 months;
    (vi) Summary of all manure, litter and process wastewater discharges 
from the production area that have occurred in the previous 12 months, 
including, for each discharge, the date of discovery, duration of 
discharge, and approximate volume; and
    (vii) A statement indicating whether the current version of the 
CAFO's nutrient management plan was developed or approved by a certified 
nutrient management planner; and
    (viii) The actual crop(s) planted and actual yield(s) for each 
field, the actual nitrogen and phosphorus content of the manure, litter, 
and process wastewater, the results of calculations conducted in 
accordance with paragraphs (e)(5)(i)(B) and (e)(5)(ii)(D) of this 
section, and the amount of manure, litter, and process wastewater 
applied to each field during the previous 12 months; and, for any CAFO 
that implements a nutrient

[[Page 264]]

management plan that addresses rates of application in accordance with 
paragraph (e)(5)(ii) of this section, the results of any soil testing 
for nitrogen and phosphorus taken during the preceding 12 months, the 
data used in calculations conducted in accordance with paragraph 
(e)(5)(ii)(D) of this section, and the amount of any supplemental 
fertilizer applied during the previous 12 months.
    (5) Terms of the nutrient management plan. Any permit issued to a 
CAFO must require compliance with the terms of the CAFO's site-specific 
nutrient management plan. The terms of the nutrient management plan are 
the information, protocols, best management practices, and other 
conditions in the nutrient management plan determined by the Director to 
be necessary to meet the requirements of paragraph (e)(1) of this 
section. The terms of the nutrient management plan, with respect to 
protocols for land application of manure, litter, or process wastewater 
required by paragraph (e)(1)(viii) of this section and, as applicable, 
40 CFR 412.4(c), must include the fields available for land application; 
field-specific rates of application properly developed, as specified in 
paragraphs (e)(5)(i) through (ii) of this section, to ensure appropriate 
agricultural utilization of the nutrients in the manure, litter, or 
process wastewater; and any timing limitations identified in the 
nutrient management plan concerning land application on the fields 
available for land application. The terms must address rates of 
application using one of the following two approaches, unless the 
Director specifies that only one of these approaches may be used:
    (i) Linear approach. An approach that expresses rates of application 
as pounds of nitrogen and phosphorus, according to the following 
specifications:
    (A) The terms include maximum application rates from manure, litter, 
and process wastewater for each year of permit coverage, for each crop 
identified in the nutrient management plan, in chemical forms determined 
to be acceptable to the Director, in pounds per acre, per year, for each 
field to be used for land application, and certain factors necessary to 
determine such rates. At a minimum, the factors that are terms must 
include: The outcome of the field-specific assessment of the potential 
for nitrogen and phosphorus transport from each field; the crops to be 
planted in each field or any other uses of a field such as pasture or 
fallow fields; the realistic yield goal for each crop or use identified 
for each field; the nitrogen and phosphorus recommendations from sources 
specified by the Director for each crop or use identified for each 
field; credits for all nitrogen in the field that will be plant 
available; consideration of multi-year phosphorus application; and 
accounting for all other additions of plant available nitrogen and 
phosphorus to the field. In addition, the terms include the form and 
source of manure, litter, and process wastewater to be land-applied; the 
timing and method of land application; and the methodology by which the 
nutrient management plan accounts for the amount of nitrogen and 
phosphorus in the manure, litter, and process wastewater to be applied.
    (B) Large CAFOs that use this approach must calculate the maximum 
amount of manure, litter, and process wastewater to be land applied at 
least once each year using the results of the most recent representative 
manure, litter, and process wastewater tests for nitrogen and phosphorus 
taken within 12 months of the date of land application; or
    (ii) Narrative rate approach. An approach that expresses rates of 
application as a narrative rate of application that results in the 
amount, in tons or gallons, of manure, litter, and process wastewater to 
be land applied, according to the following specifications:
    (A) The terms include maximum amounts of nitrogen and phosphorus 
derived from all sources of nutrients, for each crop identified in the 
nutrient management plan, in chemical forms determined to be acceptable 
to the Director, in pounds per acre, for each field, and certain factors 
necessary to determine such amounts. At a minimum, the factors that are 
terms must include: the outcome of the field-specific assessment of the 
potential for nitrogen and phosphorus transport from each field; the 
crops to be planted in each field or any other uses such as

[[Page 265]]

pasture or fallow fields (including alternative crops identified in 
accordance with paragraph (e)(5)(ii)(B) of this section); the realistic 
yield goal for each crop or use identified for each field; and the 
nitrogen and phosphorus recommendations from sources specified by the 
Director for each crop or use identified for each field. In addition, 
the terms include the methodology by which the nutrient management plan 
accounts for the following factors when calculating the amounts of 
manure, litter, and process wastewater to be land applied: Results of 
soil tests conducted in accordance with protocols identified in the 
nutrient management plan, as required by paragraph (e)(1)(vii) of this 
section; credits for all nitrogen in the field that will be plant 
available; the amount of nitrogen and phosphorus in the manure, litter, 
and process wastewater to be applied; consideration of multi-year 
phosphorus application; accounting for all other additions of plant 
available nitrogen and phosphorus to the field; the form and source of 
manure, litter, and process wastewater; the timing and method of land 
application; and volatilization of nitrogen and mineralization of 
organic nitrogen.
    (B) The terms of the nutrient management plan include alternative 
crops identified in the CAFO's nutrient management plan that are not in 
the planned crop rotation. Where a CAFO includes alternative crops in 
its nutrient management plan, the crops must be listed by field, in 
addition to the crops identified in the planned crop rotation for that 
field, and the nutrient management plan must include realistic crop 
yield goals and the nitrogen and phosphorus recommendations from sources 
specified by the Director for each crop. Maximum amounts of nitrogen and 
phosphorus from all sources of nutrients and the amounts of manure, 
litter, and process wastewater to be applied must be determined in 
accordance with the methodology described in paragraph (e)(5)(ii)(A) of 
this section.
    (C) For CAFOs using this approach, the following projections must be 
included in the nutrient management plan submitted to the Director, but 
are not terms of the nutrient management plan: The CAFO's planned crop 
rotations for each field for the period of permit coverage; the 
projected amount of manure, litter, or process wastewater to be applied; 
projected credits for all nitrogen in the field that will be plant 
available; consideration of multi-year phosphorus application; 
accounting for all other additions of plant available nitrogen and 
phosphorus to the field; and the predicted form, source, and method of 
application of manure, litter, and process wastewater for each crop. 
Timing of application for each field, insofar as it concerns the 
calculation of rates of application, is not a term of the nutrient 
management plan.
    (D) CAFOs that use this approach must calculate maximum amounts of 
manure, litter, and process wastewater to be land applied at least once 
each year using the methodology required in paragraph (e)(5)(ii)(A) of 
this section before land applying manure, litter, and process wastewater 
and must rely on the following data:
    (1) A field-specific determination of soil levels of nitrogen and 
phosphorus, including, for nitrogen, a concurrent determination of 
nitrogen that will be plant available consistent with the methodology 
required by paragraph (e)(5)(ii)(A) of this section, and for phosphorus, 
the results of the most recent soil test conducted in accordance with 
soil testing requirements approved by the Director; and
    (2) The results of most recent representative manure, litter, and 
process wastewater tests for nitrogen and phosphorus taken within 12 
months of the date of land application, in order to determine the amount 
of nitrogen and phosphorus in the manure, litter, and process wastewater 
to be applied.
    (6) Changes to a nutrient management plan. Any permit issued to a 
CAFO must require the following procedures to apply when a CAFO owner or 
operator makes changes to the CAFO's nutrient management plan previously 
submitted to the Director:
    (i) The CAFO owner or operator must provide the Director with the 
most current version of the CAFO's nutrient management plan and identify 
changes from the previous version, except that

[[Page 266]]

the results of calculations made in accordance with the requirements of 
paragraphs (e)(5)(i)(B) and (e)(5)(ii)(D) of this section are not 
subject to the requirements of paragraph (e)(6) of this section.
    (ii) The Director must review the revised nutrient management plan 
to ensure that it meets the requirements of this section and applicable 
effluent limitations and standards, including those specified in 40 CFR 
part 412, and must determine whether the changes to the nutrient 
management plan necessitate revision to the terms of the nutrient 
management plan incorporated into the permit issued to the CAFO. If 
revision to the terms of the nutrient management plan is not necessary, 
the Director must notify the CAFO owner or operator and upon such 
notification the CAFO may implement the revised nutrient management 
plan. If revision to the terms of the nutrient management plan is 
necessary, the Director must determine whether such changes are 
substantial changes as described in paragraph (e)(6)(iii) of this 
section.
    (A) If the Director determines that the changes to the terms of the 
nutrient management plan are not substantial, the Director must make the 
revised nutrient management plan publicly available and include it in 
the permit record, revise the terms of the nutrient management plan 
incorporated into the permit, and notify the owner or operator and 
inform the public of any changes to the terms of the nutrient management 
plan that are incorporated into the permit.
    (B) If the Director determines that the changes to the terms of the 
nutrient management plan are substantial, the Director must notify the 
public and make the proposed changes and the information submitted by 
the CAFO owner or operator available for public review and comment. The 
process for public comments, hearing requests, and the hearing process 
if a hearing is held must follow the procedures applicable to draft 
permits set forth in 40 CFR 124.11 through 124.13. The Director may 
establish, either by regulation or in the CAFO's permit, an appropriate 
period of time for the public to comment and request a hearing on the 
proposed changes that differs from the time period specified in 40 CFR 
124.10. The Director must respond to all significant comments received 
during the comment period as provided in 40 CFR 124.17, and require the 
CAFO owner or operator to further revise the nutrient management plan if 
necessary, in order to approve the revision to the terms of the nutrient 
management plan incorporated into the CAFO's permit. Once the Director 
incorporates the revised terms of the nutrient management plan into the 
permit, the Director must notify the owner or operator and inform the 
public of the final decision concerning revisions to the terms and 
conditions of the permit.
    (iii) Substantial changes to the terms of a nutrient management plan 
incorporated as terms and conditions of a permit include, but are not 
limited to:
    (A) Addition of new land application areas not previously included 
in the CAFO's nutrient management plan. Except that if the land 
application area that is being added to the nutrient management plan is 
covered by terms of a nutrient management plan incorporated into an 
existing NPDES permit in accordance with the requirements of paragraph 
(e)(5) of this section, and the CAFO owner or operator applies manure, 
litter, or process wastewater on the newly added land application area 
in accordance with the existing field-specific permit terms applicable 
to the newly added land application area, such addition of new land 
would be a change to the new CAFO owner or operator's nutrient 
management plan but not a substantial change for purposes of this 
section;
    (B) Any changes to the field-specific maximum annual rates for land 
application, as set forth in paragraphs (e)(5)(i) of this section, and 
to the maximum amounts of nitrogen and phosphorus derived from all 
sources for each crop, as set forth in paragraph (e)(5)(ii) of this 
section;
    (C) Addition of any crop or other uses not included in the terms of 
the CAFO's nutrient management plan and corresponding field-specific 
rates of application expressed in accordance with paragraph (e)(5) of 
this section; and

[[Page 267]]

    (D) Changes to site-specific components of the CAFO's nutrient 
management plan, where such changes are likely to increase the risk of 
nitrogen and phosphorus transport to waters of the U.S.
    (iv) For EPA-issued permits only. Upon incorporation of the revised 
terms of the nutrient management plan into the permit, 40 CFR 124.19 
specifies procedures for appeal of the permit decision. In addition to 
the procedures specified at 40 CFR 124.19, a person must have submitted 
comments or participated in the public hearing in order to appeal the 
permit decision.

Sec. 122.43  Establishing permit conditions (applicable to State
programs, see Sec. 123.25).

    (a) In addition to conditions required in all permits (Sec. Sec. 
122.41 and 122.42), the Director shall establish conditions, as required 
on a case-by-case basis, to provide for and ensure compliance with all 
applicable requirements of CWA and regulations. These shall include 
conditions under Sec. Sec. 122.46 (duration of permits), 122.47(a) 
(schedules of compliance), 122.48 (monitoring), electronic reporting 
requirements of 40 CFR part 3 (Cross-Media Electronic Reporting 
Regulation) and 40 CFR part 127 (NPDES Electronic Reporting), and, for 
EPA permits only, Sec. Sec. 122.47(b) (alternatives schedule of 
compliance) and 122.49 (considerations under Federal law).
    (b)(1) For a State issued permit, an applicable requirement is a 
State statutory or regulatory requirement which takes effect prior to 
final administrative disposition of a permit. For a permit issued by 
EPA, an applicable requirement is a statutory or regulatory requirement 
(including any interim final regulation) which takes effect prior to the 
issuance of the permit. Section 124.14 (reopening of comment period) 
provides a means for reopening EPA permit proceedings at the discretion 
of the Director where new requirements become effective during the 
permitting process and are of sufficient magnitude to make additional 
proceedings desirable. For State and EPA administered programs, an 
applicable requirement is also any requirement which takes effect prior 
to the modification or revocation and reissuance of a permit, to the 
extent allowed in Sec. 122.62.
    (2) New or reissued permits, and to the extent allowed under Sec. 
122.62 modified or revoked and reissued permits, shall incorporate each 
of the applicable requirements referenced in Sec. Sec. 122.44 and 
122.45.
    (c) Incorporation. All permit conditions shall be incorporated 
either expressly or by reference. If incorporated by reference, a 
specific citation to the applicable regulations or requirements must be 
given in the permit.

[48 FR 14153, Apr. 1, 1983, as amended at 65 FR 30908, May 15, 2000; 80 
FR 64098, Oct. 22, 2015]



Sec. 122.44  Establishing limitations, standards, and other permit
conditions (applicable to State NPDES programs, see Sec. 123.25).

    In addition to the conditions established under Sec. 122.43(a), 
each NPDES permit shall include conditions meeting the following 
requirements when applicable.
    (a)(1) Technology-based effluent limitations and standards based on: 
effluent limitations and standards promulgated under section 301 of the 
CWA, or new source performance standards promulgated under section 306 
of CWA, on case-by-case effluent limitations determined under section 
402(a)(1) of CWA, or a combination of the three, in accordance with 
Sec. 125.3 of this chapter. For new sources or new dischargers, these 
technology based limitations and standards are subject to the provisions 
of Sec. 122.29(d) (protection period).
    (2) Monitoring waivers for certain guideline-listed pollutants. (i) 
The Director may authorize a discharger subject to technology-based 
effluent limitations guidelines and standards in an NPDES permit to 
forego sampling of a pollutant found at 40 CFR Subchapter N of this 
chapter if the discharger has demonstrated through sampling and other 
technical factors that the pollutant is not present in the discharge or 
is

[[Page 268]]

present only at background levels from intake water and without any 
increase in the pollutant due to activities of the discharger.
    (ii) This waiver is good only for the term of the permit and is not 
available during the term of the first permit issued to a discharger.
    (iii) Any request for this waiver must be submitted when applying 
for a reissued permit or modification of a reissued permit. The request 
must demonstrate through sampling or other technical information, 
including information generated during an earlier permit term that the 
pollutant is not present in the discharge or is present only at 
background levels from intake water and without any increase in the 
pollutant due to activities of the discharger.
    (iv) Any grant of the monitoring waiver must be included in the 
permit as an express permit condition and the reasons supporting the 
grant must be documented in the permit's fact sheet or statement of 
basis.
    (v) This provision does not supersede certification processes and 
requirements already established in existing effluent limitations 
guidelines and standards.
    (b)(1) Other effluent limitations and standards under sections 301, 
302, 303, 307, 318 and 405 of CWA. If any applicable toxic effluent 
standard or prohibition (including any schedule of compliance specified 
in such effluent standard or prohibition) is promulgated under section 
307(a) of CWA for a toxic pollutant and that standard or prohibition is 
more stringent than any limitation on the pollutant in the permit, the 
Director shall institute proceedings under these regulations to modify 
or revoke and reissue the permit to conform to the toxic effluent 
standard or prohibition. See also Sec. 122.41(a).
    (2) Standards for sewage sludge use or disposal under section 405(d) 
of the CWA unless those standards have been included in a permit issued 
under the appropriate provisions of subtitle C of the Solid Waste 
Disposal Act, Part C of Safe Drinking Water Act, the Marine Protection, 
Research, and Sanctuaries Act of 1972, or the Clean Air Act, or under 
State permit programs approved by the Administrator. When there are no 
applicable standards for sewage sludge use or disposal, the permit may 
include requirements developed on a case-by-case basis to protect public 
health and the environment from any adverse effects which may occur from 
toxic pollutants in sewage sludge. If any applicable standard for sewage 
sludge use or disposal is promulgated under section 405(d) of the CWA 
and that standard is more stringent than any limitation on the pollutant 
or practice in the permit, the Director may initiate proceedings under 
these regulations to modify or revoke and reissue the permit to conform 
to the standard for sewage sludge use or disposal.
    (3) Requirements applicable to cooling water intake structures under 
section 316(b) of the CWA, in accordance with part 125, subparts I, J, 
and N of this chapter.
    (c) Reopener clause: For any permit issued to a treatment works 
treating domestic sewage (including ``sludge-only facilities''), the 
Director shall include a reopener clause to incorporate any applicable 
standard for sewage sludge use or disposal promulgated under section 
405(d) of the CWA. The Director may promptly modify or revoke and 
reissue any permit containing the reopener clause required by this 
paragraph if the standard for sewage sludge use or disposal is more 
stringent than any requirements for sludge use or disposal in the 
permit, or controls a pollutant or practice not limited in the permit.
    (d) Water quality standards and State requirements: any requirements 
in addition to or more stringent than promulgated effluent limitations 
guidelines or standards under sections 301, 304, 306, 307, 318 and 405 
of CWA necessary to:
    (1) Achieve water quality standards established under section 303 of 
the CWA, including State narrative criteria for water quality.
    (i) Limitations must control all pollutants or pollutant parameters 
(either conventional, nonconventional, or toxic pollutants) which the 
Director determines are or may be discharged at a level which will 
cause, have the reasonable potential to cause, or contribute to an 
excursion above any

[[Page 269]]

State water quality standard, including State narrative criteria for 
water quality.
    (ii) When determining whether a discharge causes, has the reasonable 
potential to cause, or contributes to an in-stream excursion above a 
narrative or numeric criteria within a State water quality standard, the 
permitting authority shall use procedures which account for existing 
controls on point and nonpoint sources of pollution, the variability of 
the pollutant or pollutant parameter in the effluent, the sensitivity of 
the species to toxicity testing (when evaluating whole effluent 
toxicity), and where appropriate, the dilution of the effluent in the 
receiving water.
    (iii) When the permitting authority determines, using the procedures 
in paragraph (d)(1)(ii) of this section, that a discharge causes, has 
the reasonable potential to cause, or contributes to an in-stream 
excursion above the allowable ambient concentration of a State numeric 
criteria within a State water quality standard for an individual 
pollutant, the permit must contain effluent limits for that pollutant.
    (iv) When the permitting authority determines, using the procedures 
in paragraph (d)(1)(ii) of this section, that a discharge causes, has 
the reasonable potential to cause, or contributes to an in-stream 
excursion above the numeric criterion for whole effluent toxicity, the 
permit must contain effluent limits for whole effluent toxicity.
    (v) Except as provided in this subparagraph, when the permitting 
authority determines, using the procedures in paragraph (d)(1)(ii) of 
this section, toxicity testing data, or other information, that a 
discharge causes, has the reasonable potential to cause, or contributes 
to an in-stream excursion above a narrative criterion within an 
applicable State water quality standard, the permit must contain 
effluent limits for whole effluent toxicity. Limits on whole effluent 
toxicity are not necessary where the permitting authority demonstrates 
in the fact sheet or statement of basis of the NPDES permit, using the 
procedures in paragraph (d)(1)(ii) of this section, that chemical-
specific limits for the effluent are sufficient to attain and maintain 
applicable numeric and narrative State water quality standards.
    (vi) Where a State has not established a water quality criterion for 
a specific chemical pollutant that is present in an effluent at a 
concentration that causes, has the reasonable potential to cause, or 
contributes to an excursion above a narrative criterion within an 
applicable State water quality standard, the permitting authority must 
establish effluent limits using one or more of the following options:
    (A) Establish effluent limits using a calculated numeric water 
quality criterion for the pollutant which the permitting authority 
demonstrates will attain and maintain applicable narrative water quality 
criteria and will fully protect the designated use. Such a criterion may 
be derived using a proposed State criterion, or an explicit State policy 
or regulation interpreting its narrative water quality criterion, 
supplemented with other relevant information which may include: EPA's 
Water Quality Standards Handbook, October 1983, risk assessment data, 
exposure data, information about the pollutant from the Food and Drug 
Administration, and current EPA criteria documents; or
    (B) Establish effluent limits on a case-by-case basis, using EPA's 
water quality criteria, published under section 304(a) of the CWA, 
supplemented where necessary by other relevant information; or
    (C) Establish effluent limitations on an indicator parameter for the 
pollutant of concern, provided:
    (1) The permit identifies which pollutants are intended to be 
controlled by the use of the effluent limitation;
    (2) The fact sheet required by Sec. 124.56 sets forth the basis for 
the limit, including a finding that compliance with the effluent limit 
on the indicator parameter will result in controls on the pollutant of 
concern which are sufficient to attain and maintain applicable water 
quality standards;
    (3) The permit requires all effluent and ambient monitoring 
necessary to show that during the term of the permit the limit on the 
indicator parameter continues to attain and maintain applicable water 
quality standards; and

[[Page 270]]

    (4) The permit contains a reopener clause allowing the permitting 
authority to modify or revoke and reissue the permit if the limits on 
the indicator parameter no longer attain and maintain applicable water 
quality standards.
    (vii) When developing water quality-based effluent limits under this 
paragraph the permitting authority shall ensure that:
    (A) The level of water quality to be achieved by limits on point 
sources established under this paragraph is derived from, and complies 
with all applicable water quality standards; and
    (B) Effluent limits developed to protect a narrative water quality 
criterion, a numeric water quality criterion, or both, are consistent 
with the assumptions and requirements of any available wasteload 
allocation for the discharge prepared by the State and approved by EPA 
pursuant to 40 CFR 130.7.
    (2) Attain or maintain a specified water quality through water 
quality related effluent limits established under section 302 of CWA;
    (3) Conform to the conditions to a State certification under section 
401 of the CWA that meets the requirements of Sec. 124.53 when EPA is 
the permitting authority. If a State certification is stayed by a court 
of competent jurisdiction or an appropriate State board or agency, EPA 
shall notify the State that the Agency will deem certification waived 
unless a finally effective State certification is received within sixty 
days from the date of the notice. If the State does not forward a 
finally effective certification within the sixty day period, EPA shall 
include conditions in the permit that may be necessary to meet EPA's 
obligation under section 301(b)(1)(C) of the CWA;
    (4) Conform to applicable water quality requirements under section 
401(a)(2) of CWA when the discharge affects a State other than the 
certifying State;
    (5) Incorporate any more stringent limitations, treatment standards, 
or schedule of compliance requirements established under Federal or 
State law or regulations in accordance with section 301(b)(1)(C) of CWA;
    (6) Ensure consistency with the requirements of a Water Quality 
Management plan approved by EPA under section 208(b) of CWA;
    (7) Incorporate section 403(c) criteria under part 125, subpart M, 
for ocean discharges;
    (8) Incorporate alternative effluent limitations or standards where 
warranted by ``fundamentally different factors,'' under 40 CFR part 125, 
subpart D;
    (9) Incorporate any other appropriate requirements, conditions, or 
limitations (other than effluent limitations) into a new source permit 
to the extent allowed by the National Environmental Policy Act, 42 
U.S.C. 4321 et seq. and section 511 of the CWA, when EPA is the permit 
issuing authority. (See Sec. 122.29(c)).
    (e) Technology-based controls for toxic pollutants. Limitations 
established under paragraphs (a), (b), or (d) of this section, to 
control pollutants meeting the criteria listed in paragraph (e)(1) of 
this section. Limitations will be established in accordance with 
paragraph (e)(2) of this section. An explanation of the development of 
these limitations shall be included in the fact sheet under Sec. 
124.56(b)(1)(i).
    (1) Limitations must control all toxic pollutants which the Director 
determines (based on information reported in a permit application under 
Sec. 122.21(g)(7) or in a notification under Sec. 122.42(a)(1) or on 
other information) are or may be discharged at a level greater than the 
level which can be achieved by the technology-based treatment 
requirements appropriate to the permittee under Sec. 125.3(c) of this 
chapter; or
    (2) The requirement that the limitations control the pollutants 
meeting the criteria of paragraph (e)(1) of this section will be 
satisfied by:
    (i) Limitations on those pollutants; or
    (ii) Limitations on other pollutants which, in the judgment of the 
Director, will provide treatment of the pollutants under paragraph 
(e)(1) of this section to the levels required by Sec. 125.3(c).
    (f) Notification level. A ``notification level'' which exceeds the 
notification level of Sec. 122.42(a)(1)(i), (ii) or (iii), upon a 
petition from the permittee or on the Director's initiative. This new 
notification level may not exceed the level

[[Page 271]]

which can be achieved by the technology-based treatment requirements 
appropriate to the permittee under Sec. 125.3(c)
    (g) Twenty-four hour reporting. Pollutants for which the permittee 
must report violations of maximum daily discharge limitations under 
Sec. 122.41(1)(6)(ii)(C) (24-hour reporting) shall be listed in the 
permit. This list shall include any toxic pollutant or hazardous 
substance, or any pollutant specifically identified as the method to 
control a toxic pollutant or hazardous substance.
    (h) Durations for permits, as set forth in Sec. 122.46.
    (i) Monitoring requirements. In addition to Sec. 122.48, the 
following monitoring requirements:
    (1) To assure compliance with permit limitations, requirements to 
monitor:
    (i) The mass (or other measurement specified in the permit) for each 
pollutant limited in the permit;
    (ii) The volume of effluent discharged from each outfall;
    (iii) Other measurements as appropriate including pollutants in 
internal waste streams under Sec. 122.45(i); pollutants in intake water 
for net limitations under Sec. 122.45(f); frequency, rate of discharge, 
etc., for noncontinuous discharges under Sec. 122.45(e); pollutants 
subject to notification requirements under Sec. 122.42(a); and 
pollutants in sewage sludge or other monitoring as specified in 40 CFR 
part 503; or as determined to be necessary on a case-by-case basis 
pursuant to section 405(d)(4) of the CWA.
    (iv) According to sufficiently sensitive test procedures (i.e., 
methods) approved under 40 CFR part 136 for the analysis of pollutants 
or pollutant parameters or required under 40 CFR chapter I, subchapter N 
or O.
    (A) For the purposes of this paragraph, a method is ``sufficiently 
sensitive'' when:
    (1) The method minimum level (ML) is at or below the level of the 
effluent limit established in the permit for the measured pollutant or 
pollutant parameter; or
    (2) The method has the lowest ML of the analytical methods approved 
under 40 CFR part 136 or required under 40 CFR chapter I, subchapter N 
or O for the measured pollutant or pollutant parameter.

    Note to paragraph (i)(1)(iv)(A):
    Consistent with 40 CFR part 136, applicants or permittees have the 
option of providing matrix or sample specific minimum levels rather than 
the published levels. Further, where an applicant or permittee can 
demonstrate that, despite a good faith effort to use a method that would 
otherwise meet the definition of ``sufficiently sensitive'', the 
analytical results are not consistent with the QA/QC specifications for 
that method, then the Director may determine that the method is not 
performing adequately and the Director should select a different method 
from the remaining EPA-approved methods that is sufficiently sensitive 
consistent with 40 CFR 122.44(i)(1)(iv)(A). Where no other EPA-approved 
methods exist, the Director should select a method consistent with 40 
CFR 122.44(i)(1)(iv)(B).

    (B) In the case of pollutants or pollutant parameters for which 
there are no approved methods under 40 CFR part 136 or methods are not 
otherwise required under 40 CFR chapter I, subchapter N or O, monitoring 
shall be conducted according to a test procedure specified in the permit 
for such pollutants or pollutant parameters.
    (2) Except as provided in paragraphs (i)(4) and (5) of this section, 
requirements to report monitoring results shall be established on a 
case-by-case basis with a frequency dependent on the nature and effect 
of the discharge, but in no case less than once a year. For sewage 
sludge use or disposal practices, requirements to monitor and report 
results shall be established on a case-by-case basis with a frequency 
dependent on the nature and effect of the sewage sludge use or disposal 
practice; minimally this shall be as specified in 40 CFR part 503 (where 
applicable), but in no case less than once a year. All results must be 
electronically reported in compliance with 40 CFR part 3 (including, in 
all cases, subpart D to part 3), Sec. 122.22, and 40 CFR part 127.
    (3) Requirements to report monitoring results for storm water 
discharges associated with industrial activity which are subject to an 
effluent limitation guideline shall be established on a case-by-case 
basis with a frequency dependent on the nature and effect of the 
discharge, but in no case less than once a year.

[[Page 272]]

    (4) Requirements to report monitoring results for storm water 
discharges associated with industrial activity (other than those 
addressed in paragraph (i)(3) of this section) shall be established on a 
case-by-case basis with a frequency dependent on the nature and effect 
of the discharge. At a minimum, a permit for such a discharge must 
require:
    (i) The discharger to conduct an annual inspection of the facility 
site to identify areas contributing to a storm water discharge 
associated with industrial activity and evaluate whether measures to 
reduce pollutant loadings identified in a storm water pollution 
prevention plan are adequate and properly implemented in accordance with 
the terms of the permit or whether additional control measures are 
needed;
    (ii) The discharger to maintain for a period of three years a record 
summarizing the results of the inspection and a certification that the 
facility is in compliance with the plan and the permit, and identifying 
any incidents of non-compliance;
    (iii) Such report and certification be signed in accordance with 
Sec. 122.22; and
    (iv) Permits for storm water discharges associated with industrial 
activity from inactive mining operations may, where annual inspections 
are impracticable, require certification once every three years by a 
Registered Professional Engineer that the facility is in compliance with 
the permit, or alternative requirements.
    (5) Permits which do not require the submittal of monitoring result 
reports at least annually shall require that the permittee report all 
instances of noncompliance not reported under Sec. 122.41(l) (1), (4), 
(5), and (6) at least annually.
    (j) Pretreatment program for POTWs. Requirements for POTWs to:
    (1) Identify, in terms of character and volume of pollutants, any 
Significant Industrial Users discharging into the POTW subject to 
Pretreatment Standards under section 307(b) of CWA and 40 CFR part 403.
    (2)(i) Submit a local program when required by and in accordance 
with 40 CFR part 403 to assure compliance with pretreatment standards to 
the extent applicable under section 307(b). The local program shall be 
incorporated into the permit as described in 40 CFR part 403. The 
program must require all indirect dischargers to the POTW to comply with 
the reporting requirements of 40 CFR part 403.
    (ii) Provide a written technical evaluation of the need to revise 
local limits under 40 CFR 403.5(c)(1), following permit issuance or 
reissuance.
    (3) For POTWs which are ``sludge-only facilities,'' a requirement to 
develop a pretreatment program under 40 CFR part 403 when the Director 
determines that a pretreatment program is necessary to assure compliance 
with Section 405(d) of the CWA.
    (k) Best management practices (BMPs) to control or abate the 
discharge of pollutants when:
    (1) Authorized under section 304(e) of the CWA for the control of 
toxic pollutants and hazardous substances from ancillary industrial 
activities;
    (2) Authorized under section 402(p) of the CWA for the control of 
storm water discharges;
    (3) Numeric effluent limitations are infeasible; or
    (4) The practices are reasonably necessary to achieve effluent 
limitations and standards or to carry out the purposes and intent of the 
CWA.

    Note to paragraph (k)(4):
    Additional technical information on BMPs and the elements of BMPs is 
contained in the following documents: Guidance Manual for Developing 
Best Management Practices (BMPs), October 1993, EPA No. 833/B-93-004,

    (l) Reissued permits. (1) Except as provided in paragraph (l)(2) of 
this section when a permit is renewed or reissued, interim effluent 
limitations, standards or conditions must be at least as stringent as 
the final effluent limitations, standards, or conditions in the previous 
permit (unless the circumstances on which the previous permit was based 
have materially and substantially changed since the time the permit was 
issued and would constitute cause for permit modification or revocation 
and reissuance under Sec. 122.62.)
    (2) In the case of effluent limitations established on the basis of 
Section 402(a)(1)(B) of the CWA, a permit may not be renewed, reissued, 
or modified on the basis of effluent guidelines promulgated under 
section 304(b) subsequent to the original issuance of such permit, to 
contain effluent limitations which are less stringent than the 
comparable effluent limitations in the previous permit.
    (i) Exceptions--A permit with respect to which paragraph (l)(2) of 
this section applies may be renewed, reissued, or modified to contain a 
less stringent effluent limitation applicable to a pollutant, if--
    (A) Material and substantial alterations or additions to the 
permitted facility occurred after permit issuance which justify the 
application of a less stringent effluent limitation;
    (B)(1) Information is available which was not available at the time 
of permit issuance (other than revised regulations, guidance, or test 
methods) and which would have justified the application of a less 
stringent effluent limitation at the time of permit issuance; or
    (2) The Administrator determines that technical mistakes or mistaken 
interpretations of law were made in issuing the permit under section 
402(a)(1)(b);
    (C) A less stringent effluent limitation is necessary because of 
events over which the permittee has no control and for which there is no 
reasonably available remedy;
    (D) The permittee has received a permit modification under section 
301(c), 301(g), 301(h), 301(i), 301(k), 301(n), or 316(a); or
    (E) The permittee has installed the treatment facilities required to 
meet the effluent limitations in the previous permit and has properly 
operated and maintained the facilities but has nevertheless been unable 
to achieve the previous effluent limitations, in which case the 
limitations in the reviewed, reissued, or modified permit may reflect 
the level of pollutant control actually achieved (but shall not be less 
stringent than required by effluent guidelines in effect at the time of 
permit renewal, reissuance, or modification).
    (ii) Limitations. In no event may a permit with respect to which 
paragraph (l)(2) of this section applies be renewed, reissued, or 
modified to contain an effluent limitation which is less stringent than 
required by effluent guidelines in effect at the time the permit is 
renewed, reissued, or modified. In no event may such a permit to 
discharge into waters be renewed, issued, or modified to contain a less 
stringent effluent limitation if the implementation of such limitation 
would result in a violation of a water quality standard under section 
303 applicable to such waters.
    (m) Privately owned treatment works. For a privately owned treatment 
works, any conditions expressly applicable to any user, as a limited co-
permittee, that may be necessary in the permit issued to the treatment 
works to ensure compliance with applicable requirements under this part. 
Alternatively, the Director may issue separate permits to the treatment 
works and to its users, or may require a separate permit application 
from any user. The Director's decision to issue a permit with no 
conditions applicable to

[[Page 274]]

any user, to impose conditions on one or more users, to issue separate 
permits, or to require separate applications, and the basis for that 
decision, shall be stated in the fact sheet for the draft permit for the 
treatment works.
    (n) Grants. Any conditions imposed in grants made by the 
Administrator to POTWs under sections 201 and 204 of CWA which are 
reasonably necessary for the achievement of effluent limitations under 
section 301 of CWA.
    (o) Sewage sludge. Requirements under section 405 of CWA governing 
the disposal of sewage sludge from publicly owned treatment works or any 
other treatment works treating domestic sewage for any use for which 
regulations have been established, in accordance with any applicable 
regulations.
    (p) Coast Guard. When a permit is issued to a facility that may 
operate at certain times as a means of transportation over water, a 
condition that the discharge shall comply with any applicable 
regulations promulgated by the Secretary of the department in which the 
Coast Guard is operating, that establish specifications for safe 
transportation, handling, carriage, and storage of pollutants.
    (q) Navigation. Any conditions that the Secretary of the Army 
considers necessary to ensure that navigation and anchorage will not be 
substantially impaired, in accordance with Sec. 124.59 of this chapter.
    (r) Great Lakes. When a permit is issued to a facility that 
discharges into the Great Lakes System (as defined in 40 CFR 132.2), 
conditions promulgated by the State, Tribe, or EPA pursuant to 40 CFR 
part 132.
    (s) Qualifying State, Tribal, or local programs. (1) For storm water 
discharges associated with small construction activity identified in 
Sec. 122.26(b)(15), the Director may include permit conditions that 
incorporate qualifying State, Tribal, or local erosion and sediment 
control program requirements by reference. Where a qualifying State, 
Tribal, or local program does not include one or more of the elements in 
this paragraph (s)(1), then the Director must include those elements as 
conditions in the permit. A qualifying State, Tribal, or local erosion 
and sediment control program is one that includes:
    (i) Requirements for construction site operators to implement 
appropriate erosion and sediment control best management practices;
    (ii) Requirements for construction site operators to control waste 
such as discarded building materials, concrete truck washout, chemicals, 
litter, and sanitary waste at the construction site that may cause 
adverse impacts to water quality;
    (iii) Requirements for construction site operators to develop and 
implement a storm water pollution prevention plan. (A storm water 
pollution prevention plan includes site descriptions, descriptions of 
appropriate control measures, copies of approved State, Tribal or local 
requirements, maintenance procedures, inspection procedures, and 
identification of non-storm water discharges); and
    (iv) Requirements to submit a site plan for review that incorporates 
consideration of potential water quality impacts.
    (2) For storm water discharges from construction activity identified 
in Sec. 122.26(b)(14)(x), the Director may include permit conditions 
that incorporate qualifying State, Tribal, or local erosion and sediment 
control program requirements by reference. A qualifying State, Tribal or 
local erosion and sediment control program is one that includes the 
elements listed in paragraph (s)(1) of this section and any additional 
requirements necessary to achieve the applicable technology-based 
standards of ``best available technology'' and ``best conventional 
technology'' based on the best professional judgment of the permit 
writer.

Sec. 122.45  Calculating NPDES permit conditions (applicable to State
NPDES programs, see Sec. 123.25).

    (a) Outfalls and discharge points. All permit effluent limitations, 
standards and prohibitions shall be established for each outfall or 
discharge point of

[[Page 275]]

the permitted facility, except as otherwise provided under Sec. 
122.44(k) (BMPs where limitations are infeasible) and paragraph (i) of 
this section (limitations on internal waste streams).
    (b) Production-based limitations. (1) In the case of POTWs, permit 
effluent limitations, standards, or prohibitions shall be calculated 
based on design flow.
    (2)(i) Except in the case of POTWs or as provided in paragraph 
(b)(2)(ii) of this section, calculation of any permit limitations, 
standards, or prohibitions which are based on production (or other 
measure of operation) shall be based not upon the designed production 
capacity but rather upon a reasonable measure of actual production of 
the facility. For new sources or new dischargers, actual production 
shall be estimated using projected production. The time period of the 
measure of production shall correspond to the time period of the 
calculated permit limitations; for example, monthly production shall be 
used to calculate average monthly discharge limitations.
    (ii)(A)(1) The Director may include a condition establishing 
alternate permit limitations, standards, or prohibitions based upon 
anticipated increased (not to exceed maximum production capability) or 
decreased production levels.
    (2) For the automotive manufacturing industry only, the Regional 
Administrator shall, and the State Director may establish a condition 
under paragraph (b)(2)(ii)(A)(1) of this section if the applicant 
satisfactorily demonstrates to the Director at the time the application 
is submitted that its actual production, as indicated in paragraph 
(b)(2)(i) of this section, is substantially below maximum production 
capability and that there is a reasonable potential for an increase 
above actual production during the duration of the permit.
    (B) If the Director establishes permit conditions under paragraph 
(b)(2)(ii)(A) of this section:
    (1) The permit shall require the permittee to notify the Director at 
least two business days prior to a month in which the permittee expects 
to operate at a level higher than the lowest production level identified 
in the permit. The notice shall specify the anticipated level and the 
period during which the permittee expects to operate at the alternate 
level. If the notice covers more than one month, the notice shall 
specify the reasons for the anticipated production level increase. New 
notice of discharge at alternate levels is required to cover a period or 
production level not covered by prior notice or, if during two 
consecutive months otherwise covered by a notice, the production level 
at the permitted facility does not in fact meet the higher level 
designated in the notice.
    (2) The permittee shall comply with the limitations, standards, or 
prohibitions that correspond to the lowest level of production specified 
in the permit, unless the permittee has notified the Director under 
paragraph (b)(2)(ii)(B)(1) of this section, in which case the permittee 
shall comply with the lower of the actual level of production during 
each month or the level specified in the notice.
    (3) The permittee shall submit with the DMR the level of production 
that actually occurred during each month and the limitations, standards, 
or prohibitions applicable to that level of production.
    (c) Metals. All permit effluent limitations, standards, or 
prohibitions for a metal shall be expressed in terms of ``total 
recoverable metal'' as defined in 40 CFR part 136 unless:
    (1) An applicable effluent standard or limitation has been 
promulgated under the CWA and specifies the limitation for the metal in 
the dissolved or valent or total form; or
    (2) In establishing permit limitations on a case-by-case basis under 
Sec. 125.3, it is necessary to express the limitation on the metal in 
the dissolved or valent or total form to carry out the provisions of the 
CWA; or
    (3) All approved analytical methods for the metal inherently measure 
only its dissolved form (e.g., hexavalent chromium).
    (d) Continuous discharges. For continuous discharges all permit 
effluent limitations, standards, and prohibitions, including those 
necessary to achieve water quality standards, shall unless impracticable 
be stated as:
    (1) Maximum daily and average monthly discharge limitations for all

[[Page 276]]

dischargers other than publicly owned treatment works; and
    (2) Average weekly and average monthly discharge limitations for 
POTWs.
    (e) Non-continuous discharges. Discharges which are not continuous, 
as defined in Sec. 122.2, shall be particularly described and limited, 
considering the following factors, as appropriate:
    (1) Frequency (for example, a batch discharge shall not occur more 
than once every 3 weeks);
    (2) Total mass (for example, not to exceed 100 kilograms of zinc and 
200 kilograms of chromium per batch discharge);
    (3) Maximum rate of discharge of pollutants during the discharge 
(for example, not to exceed 2 kilograms of zinc per minute); and
    (4) Prohibition or limitation of specified pollutants by mass, 
concentration, or other appropriate measure (for example, shall not 
contain at any time more than 0.1 mg/1 zinc or more than 250 grams (\1/
4\ kilogram) of zinc in any discharge).
    (f) Mass limitations. (1) All pollutants limited in permits shall 
have limitations, standards or prohibitions expressed in terms of mass 
except:
    (i) For pH, temperature, radiation, or other pollutants which cannot 
appropriately be expressed by mass;
    (ii) When applicable standards and limitations are expressed in 
terms of other units of measurement; or
    (iii) If in establishing permit limitations on a case-by-case basis 
under Sec. 125.3, limitations expressed in terms of mass are infeasible 
because the mass of the pollutant discharged cannot be related to a 
measure of operation (for example, discharges of TSS from certain mining 
operations), and permit conditions ensure that dilution will not be used 
as a substitute for treatment.
    (2) Pollutants limited in terms of mass additionally may be limited 
in terms of other units of measurement, and the permit shall require the 
permittee to comply with both limitations.
    (g) Pollutants in intake water. (1) Upon request of the discharger, 
technology-based effluent limitations or standards shall be adjusted to 
reflect credit for pollutants in the discharger's intake water if:
    (i) The applicable effluent limitations and standards contained in 
40 CFR subchapter N specifically provide that they shall be applied on a 
net basis; or
    (ii) The discharger demonstrates that the control system it proposes 
or uses to meet applicable technology-based limitations and standards 
would, if properly installed and operated, meet the limitations and 
standards in the absence of pollutants in the intake waters.
    (2) Credit for generic pollutants such as biochemical oxygen demand 
(BOD) or total suspended solids (TSS) should not be granted unless the 
permittee demonstrates that the constituents of the generic measure in 
the effluent are substantially similar to the constituents of the 
generic measure in the intake water or unless appropriate additional 
limits are placed on process water pollutants either at the outfall or 
elsewhere.
    (3) Credit shall be granted only to the extent necessary to meet the 
applicable limitation or standard, up to a maximum value equal to the 
influent value. Additional monitoring may be necessary to determine 
eligibility for credits and compliance with permit limits.
    (4) Credit shall be granted only if the discharger demonstrates that 
the intake water is drawn from the same body of water into which the 
discharge is made. The Director may waive this requirement if he finds 
that no environmental degradation will result.
    (5) This section does not apply to the discharge of raw water 
clarifier sludge generated from the treatment of intake water.
    (h) Internal waste streams. (1) When permit effluent limitations or 
standards imposed at the point of discharge are impractical or 
infeasible, effluent limitations or standards for discharges of 
pollutants may be imposed on internal waste streams before mixing with 
other waste streams or cooling water streams. In those instances, the 
monitoring required by Sec. 122.48 shall also be applied to the 
internal waste streams.
    (2) Limits on internal waste streams will be imposed only when the 
fact

[[Page 277]]

sheet under Sec. 124.56 sets forth the exceptional circumstances which 
make such limitations necessary, such as when the final discharge point 
is inaccessible (for example, under 10 meters of water), the wastes at 
the point of discharge are so diluted as to make monitoring 
impracticable, or the interferences among pollutants at the point of 
discharge would make detection or analysis impracticable.
    (i) Disposal of pollutants into wells, into POTWs or by land 
application. Permit limitations and standards shall be calculated as 
provided in Sec. 122.50.

1989; 65 FR 30909, May 15, 2000]



Sec. 122.46  Duration of permits (applicable to State programs,
see Sec. 123.25).

    (a) NPDES permits shall be effective for a fixed term not to exceed 
5 years.
    (b) Except as provided in Sec. 122.6, the term of a permit shall 
not be extended by modification beyond the maximum duration specified in 
this section.
    (c) The Director may issue any permit for a duration that is less 
than the full allowable term under this section.
    (d) A permit may be issued to expire on or after the statutory 
deadline set forth in section 301(b)(2) (A), (C), and (E), if the permit 
includes effluent limitations to meet the requirements of section 
301(b)(2) (A), (C), (D), (E) and (F), whether or not applicable effluent 
limitations guidelines have been promulgated or approved.
    (e) A determination that a particular discharger falls within a 
given industrial category for purposes of setting a permit expiration 
date under paragraph (d) of this section is not conclusive as to the 
discharger's inclusion in that industrial category for any other 
purposes, and does not prejudice any rights to challenge or change that 
inclusion at the time that a permit based on that determination is 
formulated.

[48 FR 14153, Apr. 1, 1983, as amended at 49 FR 31842, Aug. 8, 1984; 50 
FR 6940, Feb. 19, 1985; 60 FR 33931, June 29, 1995]



Sec. 122.47  Schedules of compliance.

    (a) General (applicable to State programs, see Sec. 123.25). The 
permit may, when appropriate, specify a schedule of compliance leading 
to compliance with CWA and regulations.
    (1) Time for compliance. Any schedules of compliance under this 
section shall require compliance as soon as possible, but not later than 
the applicable statutory deadline under the CWA.
    (2) The first NPDES permit issued to a new source or a new 
discharger shall contain a schedule of compliance only when necessary to 
allow a reasonable opportunity to attain compliance with requirements 
issued or revised after commencement of construction but less than three 
years before commencement of the relevant discharge. For recommencing 
dischargers, a schedule of compliance shall be available only when 
necessary to allow a reasonable opportunity to attain compliance with 
requirements issued or revised less than three years before 
recommencement of discharge.
    (3) Interim dates. Except as provided in paragraph (b)(1)(ii) of 
this section, if a permit establishes a schedule of compliance which 
exceeds 1 year from the date of permit issuance, the schedule shall set 
forth interim requirements and the dates for their achievement.
    (i) The time between interim dates shall not exceed 1 year, except 
that in the case of a schedule for compliance with standards for sewage 
sludge use and disposal, the time between interim dates shall not exceed 
six months.
    (ii) If the time necessary for completion of any interim requirement 
(such as the construction of a control facility) is more than 1 year and 
is not readily divisible into stages for completion, the permit shall 
specify interim dates for the submission of reports of progress toward 
completion of the interim requirements and indicate a projected 
completion date.
    Note: Examples of interim requirements include: (a) Submit a 
complete Step 1 construction grant (for POTWs); (b) let a contract for 
construction of required facilities; (c) commence construction of 
required facilities; (d) complete construction of required facilities.
    (4) Reporting. The permit shall be written to require that no later 
than 14 days following each interim date and the final date of 
compliance, the permittee shall notify the Director in writing of its 
compliance or noncompliance with the interim or final

[[Page 278]]

requirements, or submit progress reports if paragraph (a)(3)(ii) is 
applicable.
    (b) Alternative schedules of compliance. An NPDES permit applicant 
or permittee may cease conducting regulated activities (by terminating 
of direct discharge for NPDES sources) rather than continuing to operate 
and meet permit requirements as follows:
    (1) If the permittee decides to cease conducting regulated 
activities at a given time within the term of a permit which has already 
been issued:
    (i) The permit may be modified to contain a new or additional 
schedule leading to timely cessation of activities; or
    (ii) The permittee shall cease conducting permitted activities 
before non-compliance with any interim or final compliance schedule 
requirement already specified in the permit.
    (2) If the decision to cease conducting regulated activities is made 
before issuance of a permit whose term will include the termination 
date, the permit shall contain a schedule leading to termination which 
will ensure timely compliance with applicable requirements no later than 
the statutory deadline.
    (3) If the permittee is undecided whether to cease conducting 
regulated activities, the Director may issue or modify a permit to 
contain two schedules as follows:
    (i) Both schedules shall contain an identical interim deadline 
requiring a final decision on whether to cease conducting regulated 
activities no later than a date which ensures sufficient time to comply 
with applicable requirements in a timely manner if the decision is to 
continue conducting regulated activities;
    (ii) One schedule shall lead to timely compliance with applicable 
requirements, no later than the statutory deadline;
    (iii) The second schedule shall lead to cessation of regulated 
activities by a date which will ensure timely compliance with applicable 
requirements no later than the statutory deadline.
    (iv) Each permit containing two schedules shall include a 
requirement that after the permittee has made a final decision under 
paragraph (b)(3)(i) of this section it shall follow the schedule leading 
to compliance if the decision is to continue conducting regulated 
activities, and follow the schedule leading to termination if the 
decision is to cease conducting regulated activities.
    (4) The applicant's or permittee's decision to cease conducting 
regulated activities shall be evidenced by a firm public commitment 
satisfactory to the Director, such as a resolution of the board of 
directors of a corporation.

15, 2000]



Sec. 122.48  Requirements for recording and reporting of monitoring
results (applicable to State programs, see Sec. 123.25).

    All permits shall specify:
    (a) Requirements concerning the proper use, maintenance, and 
installation, when appropriate, of monitoring equipment or methods 
(including biological monitoring methods when appropriate);
    (b) Required monitoring including type, intervals, and frequency 
sufficient to yield data which are representative of the monitored 
activity including, when appropriate, continuous monitoring;
    (c) Applicable reporting requirements based upon the impact of the 
regulated activity and as specified in 40 CFR part 3 (Cross-Media 
Electronic Reporting Regulation), Sec. 122.44, and 40 CFR part 127 
(NPDES Electronic Reporting). Reporting shall be no less frequent than 
specified in Sec. 122.44. EPA will maintain the start dates for the 
electronic reporting of monitoring results for each state on its Web 
site.

Sec. 122.49  Considerations under Federal law.

    The following is a list of Federal laws that may apply to the 
issuance of permits under these rules. When any of these laws is 
applicable, its procedures must be followed. When the applicable law 
requires consideration or adoption

[[Page 279]]

of particular permit conditions or requires the denial of a permit, 
those requirements also must be followed.
    (a) The Wild and Scenic Rivers Act, 16 U.S.C. 1273 et seq. section 7 
of the Act prohibits the Regional Administrator from assisting by 
license or otherwise the construction of any water resources project 
that would have a direct, adverse effect on the values for which a 
national wild and scenic river was established.
    (b) The National Historic Preservation Act of 1966, 16 U.S.C. 470 et 
seq. section 106 of the Act and implementing regulations (36 CFR part 
800) require the Regional Administrator, before issuing a license, to 
adopt measures when feasible to mitigate potential adverse effects of 
the licensed activity and properties listed or eligible for listing in 
the National Register of Historic Places. The Act's requirements are to 
be implemented in cooperation with State Historic Preservation Officers 
and upon notice to, and when appropriate, in consultation with the 
Advisory Council on Historic Preservation.
    (c) The Endangered Species Act, 16 U.S.C. 1531 et seq. section 7 of 
the Act and implementing regulations (50 CFR part 402) require the 
Regional Administrator to ensure, in consultation with the Secretary of 
the Interior or Commerce, that any action authorized by EPA is not 
likely to jeopardize the continued existence of any endangered or 
threatened species or adversely affect its critical habitat.
    (d) The Coastal Zone Management Act, 16 U.S.C. 1451 et seq. section 
307(c) of the Act and implementing regulations (15 CFR part 930) 
prohibit EPA from issuing a permit for an activity affecting land or 
water use in the coastal zone until the applicant certifies that the 
proposed activity complies with the State Coastal Zone Management 
program, and the State or its designated agency concurs with the 
certification (or the Secretary of Commerce overrides the State's 
nonconcurrence).
    (e) The Fish and Wildlife Coordination Act, 16 U.S.C. 661 et seq., 
requires that the Regional Administrator, before issuing a permit 
proposing or authorizing the impoundment (with certain exemptions), 
diversion, or other control or modification of any body of water, 
consult with the appropriate State agency exercising jurisdiction over 
wildlife resources to conserve those resources.
    (f) Executive orders. [Reserved]
    (g) The National Environmental Policy Act, 42 U.S.C. 4321 et seq., 
may require preparation of an Environmental Impact Statement and 
consideration of EIS-related permit conditions (other than effluent 
limitations) as provided in Sec. 122.29(c).

(Clean Water Act (33 U.S.C. 1251 et seq.), Safe Drinking Water Act (42 
U.S.C. 300f et seq.), Clean Air Act (42 U.S.C. 7401 et seq.), Resource 
Conservation and Recovery Act (42 U.S.C. 6901 et seq.))

Sec. 122.50  Disposal of pollutants into wells, into publicly owned 
treatment works or by land application (applicable to State NPDES
programs, see Sec. 123.25).

    (a) When part of a discharger's process wastewater is not being 
discharged into waters of the United States or contiguous zone because 
it is disposed into a well, into a POTW, or by land application thereby 
reducing the flow or level of pollutants being discharged into waters of 
the United States, applicable effluent standards and limitations for the 
discharge in an NPDES permit shall be adjusted to reflect the reduced 
raw waste resulting from such disposal. Effluent limitations and 
standards in the permit shall be calculated by one of the following 
methods:
    (1) If none of the waste from a particular process is discharged 
into waters of the United States, and effluent limitations guidelines 
provide separate allocation for wastes from that process, all 
allocations for the process shall be eliminated from calculation of 
permit effluent limitations or standards.
    (2) In all cases other than those described in paragraph (a)(1) of 
this section, effluent limitations shall be adjusted by multiplying the 
effluent limitation derived by applying effluent limitation guidelines 
to the total waste stream by the amount of wastewater

[[Page 280]]

flow to be treated and discharged into waters of the United States, and 
dividing the result by the total wastewater flow. Effluent limitations 
and standards so calculated may be further adjusted under part 125, 
subpart D to make them more or less stringent if discharges to wells, 
publicly owned treatment works, or by land application change the 
character or treatability of the pollutants being discharged to 
receiving waters. This method may be algebraically expressed as:
[GRAPHIC] [TIFF OMITTED] TR23MR95.119

where P is the permit effluent limitation, E is the limitation derived 
by applying effluent guidelines to the total wastestream, N is the 
wastewater flow to be treated and discharged to waters of the United 
States, and T is the total wastewater flow.

    (b) Paragraph (a) of this section does not apply to the extent that 
promulgated effluent limitations guidelines:
    (1) Control concentrations of pollutants discharged but not mass; or
    (2) Specify a different specific technique for adjusting effluent 
limitations to account for well injection, land application, or disposal 
into POTWs.
    (c) Paragraph (a) of this section does not alter a discharger's 
obligation to meet any more stringent requirements established under 
Sec. Sec. 122.41, 122.42, 122.43, and 122.44.

    Subpart D_Transfer, Modification, Revocation and Reissuance, and 
                         Termination of Permits



Sec. 122.61  Transfer of permits (applicable to State programs, 
see Sec. 123.25).

    (a) Transfers by modification. Except as provided in paragraph (b) 
of this section, a permit may be transferred by the permittee to a new 
owner or operator only if the permit has been modified or revoked and 
reissued (under Sec. 122.62(b)(2)), or a minor modification made (under 
Sec. 122.63(d)), to identify the new permittee and incorporate such 
other requirements as may be necessary under CWA.
    (b) Automatic transfers. As an alternative to transfers under 
paragraph (a) of this section, any NPDES permit may be automatically 
transferred to a new permittee if:
    (1) The current permittee notifies the Director at least 30 days in 
advance of the proposed transfer date in paragraph (b)(2) of this 
section;
    (2) The notice includes a written agreement between the existing and 
new permittees containing a specific date for transfer of permit 
responsibility, coverage, and liability between them; and
    (3) The Director does not notify the existing permittee and the 
proposed new permittee of his or her intent to modify or revoke and 
reissue the permit. A modification under this subparagraph may also be a 
minor modification under Sec. 122.63. If this notice is not received, 
the transfer is effective on the date specified in the agreement 
mentioned in paragraph (b)(2) of this section.



Sec. 122.62  Modification or revocation and reissuance of permits
(applicable to State programs, see Sec. 123.25).

    When the Director receives any information (for example, inspects 
the facility, receives information submitted by the permittee as 
required in the permit (see Sec. 122.41), receives a request for 
modification or revocation and reissuance under Sec. 124.5, or conducts 
a review of the permit file) he or she may determine whether or not one 
or more of the causes listed in paragraphs (a) and (b) of this section 
for modification or revocation and reissuance or both exist. If cause 
exists, the Director may modify or revoke and reissue the permit 
accordingly, subject to the limitations of Sec. 124.5(c), and may 
request an updated application if necessary. When a permit is modified, 
only the conditions subject to modification are reopened. If a permit is 
revoked and reissued, the entire permit is reopened and subject to 
revision and the permit is reissued for a new term. See Sec. 
124.5(c)(2). If cause does not exist under this section or Sec. 122.63, 
the Director shall not modify or revoke and reissue the permit. If a 
permit modification satisfies the criteria in Sec. 122.63 for ``minor 
modifications'' the permit may

[[Page 281]]

be modified without a draft permit or public review. Otherwise, a draft 
permit must be prepared and other procedures in part 124 (or procedures 
of an approved State program) followed.
    (a) Causes for modification. The following are causes for 
modification but not revocation and reissuance of permits except when 
the permittee requests or agrees.
    (1) Alterations. There are material and substantial alterations or 
additions to the permitted facility or activity (including a change or 
changes in the permittee's sludge use or disposal practice) which 
occurred after permit issuance which justify the application of permit 
conditions that are different or absent in the existing permit.

    Note: Certain reconstruction activities may cause the new source 
provisions of Sec. 122.29 to be applicable.

    (2) Information. The Director has received new information. Permits 
may be modified during their terms for this cause only if the 
information was not available at the time of permit issuance (other than 
revised regulations, guidance, or test methods) and would have justified 
the application of different permit conditions at the time of issuance. 
For NPDES general permits (Sec. 122.28) this cause includes any 
information indicating that cumulative effects on the environment are 
unacceptable. For new source or new discharger NPDES permits Sec. Sec. 
122.21, 122.29), this cause shall include any significant information 
derived from effluent testing required under Sec. 122.21(k)(5)(vi) or 
Sec. 122.21(h)(4)(iii) after issuance of the permit.
    (3) New regulations. The standards or regulations on which the 
permit was based have been changed by promulgation of amended standards 
or regulations or by judicial decision after the permit was issued. 
Permits may be modified during their terms for this cause only as 
follows:
    (i) For promulgation of amended standards or regulations, when:
    (A) The permit condition requested to be modified was based on a 
promulgated effluent limitation guideline, EPA approved or promulgated 
water quality standards, or the Secondary Treatment Regulations under 
part 133; and
    (B) EPA has revised, withdrawn, or modified that portion of the 
regulation or effluent limitation guideline on which the permit 
condition was based, or has approved a State action with regard to a 
water quality standard on which the permit condition was based; and
    (C) A permittee requests modification in accordance with Sec. 124.5 
within ninety (90) days after Federal Register notice of the action on 
which the request is based.
    (ii) For judicial decisions, a court of competent jurisdiction has 
remanded and stayed EPA promulgated regulations or effluent limitation 
guidelines, if the remand and stay concern that portion of the 
regulations or guidelines on which the permit condition was based and a 
request is filed by the permittee in accordance with Sec. 124.5 within 
ninety (90) days of judicial remand.
    (iii) For changes based upon modified State certifications of NPDES 
permits, see Sec. 124.55(b).
    (4) Compliance schedules. The Director determines good cause exists 
for modification of a compliance schedule, such as an act of God, 
strike, flood, or materials shortage or other events over which the 
permittee has little or no control and for which there is no reasonably 
available remedy. However, in no case may an NPDES compliance schedule 
be modified to extend beyond an applicable CWA statutory deadline. See 
also Sec. 122.63(c) (minor modifications) and paragraph (a)(14) of this 
section (NPDES innovative technology).
    (5) When the permittee has filed a request for a variance under CWA 
section 301(c), 301(g), 301(h), 301(i), 301(k), or 316(a) or for 
``fundamentally different factors'' within the time specified in Sec. 
122.21 or Sec. 125.27(a).
    (6) 307(a) toxics. When required to incorporate an applicable 307(a) 
toxic effluent standard or prohibition (see Sec. 122.44(b)).
    (7) Reopener. When required by the ``reopener'' conditions in a 
permit, which are established in the permit under Sec. 122.44(b) (for 
CWA toxic effluent limitations and Standards for sewage sludge use or 
disposal, see also Sec. 122.44(c)) or 40 CFR 403.18(e) (Pretreatment 
program).

[[Page 282]]

    (8)(i) Net limits. Upon request of a permittee who qualifies for 
effluent limitations on a net basis under Sec. 122.45(g).
    (ii) When a discharger is no longer eligible for net limitations, as 
provided in Sec. 122.45(g)(1)(ii).
    (9) Pretreatment. As necessary under 40 CFR 403.8(e) (compliance 
schedule for development of pretreatment program).
    (10) Failure to notify. Upon failure of an approved State to notify, 
as required by section 402(b)(3), another State whose waters may be 
affected by a discharge from the approved State.
    (11) Non-limited pollutants. When the level of discharge of any 
pollutant which is not limited in the permit exceeds the level which can 
be achieved by the technology-based treatment requirements appropriate 
to the permittee under Sec. 125.3(c).
    (12) Notification levels. To establish a ``notification level'' as 
provided in Sec. 122.44(f).
    (13) Compliance schedules. To modify a schedule of compliance to 
reflect the time lost during construction of an innovative or 
alternative facility, in the case of a POTW which has received a grant 
under section 202(a)(3) of CWA for 100% of the costs to modify or 
replace facilities constructed with a grant for innovative and 
alternative wastewater technology under section 202(a)(2). In no case 
shall the compliance schedule be modified to extend beyond an applicable 
CWA statutory deadline for compliance.
    (14) For a small MS4, to include an effluent limitation requiring 
implementation of a minimum control measure or measures as specified in 
Sec. 122.34(b) when:
    (i) The permit does not include such measure(s) based upon the 
determination that another entity was responsible for implementation of 
the requirement(s); and
    (ii) The other entity fails to implement measure(s) that satisfy the 
requirement(s).
    (15) To correct technical mistakes, such as errors in calculation, 
or mistaken interpretations of law made in determining permit 
conditions.
    (16) When the discharger has installed the treatment technology 
considered by the permit writer in setting effluent limitations imposed 
under section 402(a)(1) of the CWA and has properly operated and 
maintained the facilities but nevertheless has been unable to achieve 
those effluent limitations. In this case, the limitations in the 
modified permit may reflect the level of pollutant control actually 
achieved (but shall not be less stringent than required by a 
subsequently promulgated effluent limitations guideline).
    (17) Nutrient Management Plans. The incorporation of the terms of a 
CAFO's nutrient management plan into the terms and conditions of a 
general permit when a CAFO obtains coverage under a general permit in 
accordance with Sec. Sec. 122.23(h) and 122.28 is not a cause for 
modification pursuant to the requirements of this section.
    (18) Land application plans. When required by a permit condition to 
incorporate a land application plan for beneficial reuse of sewage 
sludge, to revise an existing land application plan, or to add a land 
application plan.
    (b) Causes for modification or revocation and reissuance. The 
following are causes to modify or, alternatively, revoke and reissue a 
permit:
    (1) Cause exists for termination under Sec. 122.64, and the 
Director determines that modification or revocation and reissuance is 
appropriate.
    (2) The Director has received notification (as required in the 
permit, see Sec. 122.41(l)(3)) of a proposed transfer of the permit. A 
permit also may be modified to reflect a transfer after the effective 
date of an automatic transfer (Sec. 122.61(b)) but will not be revoked 
and reissued after the effective date of the transfer except upon the 
request of the new permittee.

Sec. 122.63  Minor modifications of permits.

    Upon the consent of the permittee, the Director may modify a permit 
to make the corrections or allowances for

[[Page 283]]

changes in the permitted activity listed in this section, without 
following the procedures of part 124. Any permit modification not 
processed as a minor modification under this section must be made for 
cause and with part 124 draft permit and public notice as required in 
Sec. 122.62. Minor modifications may only:
    (a) Correct typographical errors;
    (b) Require more frequent monitoring or reporting by the permittee;
    (c) Change an interim compliance date in a schedule of compliance, 
provided the new date is not more than 120 days after the date specified 
in the existing permit and does not interfere with attainment of the 
final compliance date requirement; or
    (d) Allow for a change in ownership or operational control of a 
facility where the Director determines that no other change in the 
permit is necessary, provided that a written agreement containing a 
specific date for transfer of permit responsibility, coverage, and 
liability between the current and new permittees has been submitted to 
the Director.
    (e)(1) Change the construction schedule for a discharger which is a 
new source. No such change shall affect a discharger's obligation to 
have all pollution control equipment installed and in operation prior to 
discharge under Sec. 122.29.
    (2) Delete a point source outfall when the discharge from that 
outfall is terminated and does not result in discharge of pollutants 
from other outfalls except in accordance with permit limits.
    (f) Require electronic reporting requirements (to replace paper 
reporting requirements) including those specified in 40 CFR part 3 
(Cross-Media Electronic Reporting Regulation) and 40 CFR part 127 (NPDES 
Electronic Reporting).
    (g) Incorporate conditions of a POTW pretreatment program that has 
been approved in accordance with the procedures in 40 CFR 403.11 (or a 
modification thereto that has been approved in accordance with the 
procedures in 40 CFR 403.18) as enforceable conditions of the POTW's 
permits.
    (h) Incorporate changes to the terms of a CAFO's nutrient management 
plan that have been revised in accordance with the requirements of Sec. 
122.42(e)(6).

Sec. 122.64  Termination of permits (applicable to State programs,
see Sec. 123.25).

    (a) The following are causes for terminating a permit during its 
term, or for denying a permit renewal application:
    (1) Noncompliance by the permittee with any condition of the permit;
    (2) The permittee's failure in the application or during the permit 
issuance process to disclose fully all relevant facts, or the 
permittee's misrepresentation of any relevant facts at any time;
    (3) A determination that the permitted activity endangers human 
health or the environment and can only be regulated to acceptable levels 
by permit modification or termination; or
    (4) A change in any condition that requires either a temporary or 
permanent reduction or elimination of any discharge or sludge use or 
disposal practice controlled by the permit (for example, plant closure 
or termination of discharge by connection to a POTW).
    (b) The Director shall follow the applicable procedures in part 124 
or part 22 of this chapter, as appropriate (or State procedures 
equivalent to part 124) in terminating any NPDES permit under this 
section, except that if the entire discharge is permanently terminated 
by elimination of the flow or by connection to a POTW (but not by land 
application or disposal into a well), the Director may terminate the 
permit by notice to the permittee. Termination by notice shall be 
effective 30 days after notice is sent, unless the permittee objects 
within that time. If the permittee objects during that period, the 
Director shall follow part 124 of this chapter or applicable State 
procedures for termination. Expedited permit termination procedures are 
not available to permittees that are subject to pending State and/or 
Federal enforcement actions including citizen suits brought under State 
or Federal

[[Page 284]]

law. If requesting expedited permit termination procedures, a permittee 
must certify that it is not subject to any pending State or Federal 
enforcement actions including citizen suits brought under State or 
Federal law. State-authorized NPDES programs are not required to use 
part 22 of this chapter procedures for NPDES permit terminations.
    (c) Permittees that wish to terminate their permit must submit a 
Notice of Termination (NOT) to their permitting authority. If requesting 
expedited permit termination procedures, a permittee must certify in the 
NOT that it is not subject to any pending State or Federal enforcement 
actions including citizen suits brought under State or Federal law. As 
of December 21, 2020 all NOTs submitted in compliance with this section 
must be submitted electronically by the permittee to the Director or 
initial recipient, as defined in 40 CFR 127.2(b), in compliance with 
this section and 40 CFR part 3 (including, in all cases, subpart D), 
Sec. 122.22, and 40 CFR part 127. Part 127 is not intended to undo 
existing requirements for electronic reporting. Prior to this date, and 
independent of part 127, the permittee may be required to report 
electronically if specified by a particular permit or if required to do 
so by state law.

                            Subpart A_General



Sec. 123.1  Purpose and scope.

    (a) This part specifies the procedures EPA will follow in approving, 
revising, and withdrawing State programs and the requirements State 
programs must meet to be approved by the Administrator under sections 
318, 402, and 405(a) (National Pollutant Discharge Elimination System--
NPDES) of the CWA. This part also specifies the procedures EPA will 
follow in approving, revising, and withdrawing State programs under 
section 405(f) (sludge management programs) of the CWA. The requirements 
that a State sewage sludge management program must meet for approval by 
the Administrator under section 405(f) are set out at 40 CFR part 501.
    (b) These regulations are promulgated under the authority of 
sections 304(i), 101(e), 405, and 518(e) of the CWA, and implement the 
requirements of those sections.
    (c) The Administrator will approve State programs which conform to 
the applicable requirements of this part. A State NPDES program will not 
be approved by the Administrator under section 402 of CWA unless it has 
authority to control the discharges specified in sections 318 and 405(a) 
of CWA. Permit programs under sections 318 and 405(a) will not be 
approved independent of a section 402 program.
    (d)(1) Upon approval of a State program, the Administrator shall 
suspend the issuance of Federal permits for those activities subject to 
the approved State program. After program approval EPA shall retain 
jurisdiction over any permits (including general permits) which it has 
issued unless arrangements have been made with the State in the 
Memorandum of Agreement for the State to assume responsibility for these 
permits. Retention of jurisdiction shall include the processing of any 
permit appeals, modification requests, or variance requests; the conduct 
of inspections, and the receipt and review of self-monitoring reports. 
If any permit appeal, modification request or variance request is not 
finally resolved when the federally issued permit expires, EPA may, with 
the consent of the State, retain jurisdiction until the matter is 
resolved.
    (2) The procedures outlined in the preceding paragraph (d)(1) of 
this section for suspension of permitting authority and transfer of 
existing permits will also apply when EPA approves an Indian Tribe's 
application to operate a State program and a State was the authorized 
permitting authority under Sec. 123.23(b) for activities within the 
scope of the newly approved program. The authorized State will retain 
jurisdiction over its existing permits as described in paragraph (d)(1) 
of this section absent a different arrangement stated in the Memorandum 
of Agreement executed between EPA and the Tribe.
    (e) Upon submission of a complete program, EPA will conduct a public 
hearing, if interest is shown, and determine whether to approve or 
disapprove the program taking into consideration the requirements of 
this part, the CWA and any comments received.
    (f) Any State program approved by the Administrator shall at all 
times be conducted in accordance with the requirements of this part.

[[Page 294]]

    (g)(1) Except as may be authorized pursuant to paragraph (g)(2) of 
this section or excluded by Sec. 122.3, the State program must prohibit 
all point source discharges of pollutants, all discharges into 
aquaculture projects, and all disposal of sewage sludge which results in 
any pollutant from such sludge entering into any waters of the United 
States within the State's jurisdiction except as authorized by a permit 
in effect under the State program or under section 402 of CWA. NPDES 
authority may be shared by two or more State agencies but each agency 
must have Statewide jurisdiction over a class of activities or 
discharges. When more than one agency is responsible for issuing 
permits, each agency must make a submission meeting the requirements of 
Sec. 123.21 before EPA will begin formal review.
    (2) A State may seek approval of a partial or phased program in 
accordance with section 402(n) of the CWA.
    (h) In many cases, States (other than Indian Tribes) will lack 
authority to regulate activities on Indian lands. This lack of authority 
does not impair that State's ability to obtain full program approval in 
accordance with this part, i.e., inability of a State to regulate 
activities on Indian lands does not constitute a partial program. EPA 
will administer the program on Indian lands if a State (or Indian Tribe) 
does not seek or have authority to regulate activities on Indian lands.
    Note: States are advised to contact the United States Department of 
the Interior, Bureau of Indian Affairs, concerning authority over Indian 
lands.
    (i) Nothing in this part precludes a State from:
    (1) Adopting or enforcing requirements which are more stringent or 
more extensive than those required under this part;
    (2) Operating a program with a greater scope of coverage than that 
required under this part. If an approved State program has greater scope 
of coverage than required by Federal law the additional coverage is not 
part of the Federally approved program.
    Note: For example, if a State requires permits for discharges into 
publicly owned treatment works, these permits are not NPDES permits.

    The definitions in part 122 apply to all subparts of this part.

[63 FR 45122, Aug. 24, 1998]



Sec. 123.3  Coordination with other programs.

    Issuance of State permits under this part may be coordinated with 
issuance of RCRA, UIC, NPDES, and 404 permits whether they are 
controlled by the State, EPA, or the Corps of Engineers. See Sec. 
124.4.



                   Subpart B_State Program Submissions



Sec. 123.21  Elements of a program submission.

    (a) Any State that seeks to administer a program under this part 
shall submit to the Administrator at least three copies of a program 
submission. The submission shall contain the following:
    (1) A letter from the Governor of the State (or in the case of an 
Indian Tribe in accordance with Sec. 123.33(b), the Tribal authority 
exercising powers substantially similar to those of a State Governor) 
requesting program approval;
    (2) A complete program description, as required by Sec. 123.22, 
describing how the State intends to carry out its responsibilities under 
this part;
    (3) An Attorney General's statement as required by Sec. 123.23;
    (4) A Memorandum of Agreement with the Regional Administrator as 
required by Sec. 123.24;
    (5) Copies of all applicable State statutes and regulations, 
including those governing State administrative procedures;
    (b)(1) Within 30 days of receipt by EPA of a State program 
submission, EPA will notify the State whether its submission is 
complete. If EPA finds that a State's submission is complete, the 
statutory review period (i.e., the period of time allotted for formal 
EPA review of a proposed State program

[[Page 295]]

under CWA) shall be deemed to have begun on the date of receipt of the 
State's submission. If EPA finds that a State's submission is 
incomplete, the statutory review period shall not begin until all the 
necessary information is received by EPA.
    (2) In the case of an Indian Tribe eligible under Sec. 123.33(b), 
EPA shall take into consideration the contents of the Tribe's request 
submitted under Sec. 123.32, in determining if the program submission 
required by Sec. 123.21(a) is complete.
    (c) If the State's submission is materially changed during the 
statutory review period, the statutory review period shall begin again 
upon receipt of the revised submission.
    (d) The State and EPA may extend the statutory review period by 
agreement.

[48 FR 14178, Apr. 1, 1983; 50 FR 6941, Feb. 19, 1985, as amended at 58 
FR 67981, Dec. 22, 1993; 59 FR 64343, Dec. 14, 1994]



Sec. 123.22  Program description.

    Any State that seeks to administer a program under this part shall 
submit a description of the program it proposes to administer in lieu of 
the Federal program under State law or under an interstate compact. The 
program description shall include:
    (a) A description in narrative form of the scope, structure, 
coverage and processes of the State program.
    (b) A description (including organization charts) of the 
organization and structure of the State agency or agencies which will 
have responsibility for administering the program, including the 
information listed below. If more than one agency is responsible for 
administration of a program, each agency must have statewide 
jurisdiction over a class of activities. The responsibilities of each 
agency must be delineated, their procedures for coordination set forth, 
and an agency may be designated as a ``lead agency'' to facilitate 
communications between EPA and the State agencies having program 
responsibility. If the State proposes to administer a program of greater 
scope of coverage than is required by Federal law, the information 
provided under this paragraph shall indicate the resources dedicated to 
administering the Federally required portion of the program.
    (1) A description of the State agency staff who will carry out the 
State program, including the number, occupations, and general duties of 
the employees. The State need not submit complete job descriptions for 
every employee carrying out the State program.
    (2) An itemization of the estimated costs of establishing and 
administering the program for the first two years after approval, 
including cost of the personnel listed in paragraph (b)(1) of this 
section, cost of administrative support, and cost of technical support.
    (3) An itemization of the sources and amounts of funding, including 
an estimate of Federal grant money, available to the State Director for 
the first two years after approval to meet the costs listed in paragraph 
(b)(2) of this section, identifying any restrictions or limitations upon 
this funding.
    (c) A description of applicable State procedures, including 
permitting procedures and any State administrative or judicial review 
procedures;
    (d) Copies of the permit form(s), application form(s), and reporting 
form(s) the State intends to employ in its program. Forms used by States 
need not be identical to the forms used by EPA but should require the 
same basic information, except that State NPDES programs are required to 
use standard Discharge Monitoring Reports (DMR). The State need not 
provide copies of uniform national forms it intends to use but should 
note its intention to use such forms.
    Note: States are encouraged to use uniform national forms 
established by the Administrator. If uniform national forms are used, 
they may be modified to include the State Agency's name, address, logo, 
and other similar information, as appropriate, in place of EPA's.
    (e) A complete description of the State's compliance tracking and 
enforcement program.
    (f) In the case of Indian Tribes eligible under Sec. 123.33(b), if 
a State has been authorized by EPA to issue permits on the Federal 
Indian reservation in accordance with Sec. 123.23(b), a description of 
how responsibility for pending permit applications, existing permits, 
and supporting files will be transferred from the State to the eligible 
Indian

[[Page 296]]

Tribe. To the maximum extent practicable, this should include a 
Memorandum of Agreement negotiated between the State and the Indian 
Tribe addressing the arrangements for such transfer.
    (g) A state, tribe, or territory that newly seeks to implement an 
NPDES program after March 21, 2016 must describe whether the state, 
tribe, or territory will be the initial recipient of electronic NPDES 
information from NPDES-regulated facilities for specific NPDES data 
groups (see 40 CFR 127.2(c) and 127.27). In this program description, 
the state, tribe, or territory must identify the specific NPDES data 
groups for which the state, tribe, or territory will be the initial 
recipient of electronic NPDES information from NPDES-regulated 
facilities and how the electronic data system of the state, tribe, or 
territory will be compliant with 40 CFR part 3 (including, in all cases, 
subpart D to part 3), Sec. 123.26, and 40 CFR part 127.

1994; 63 FR 45122, Aug. 24, 1998; 80 FR 64099, Oct. 22, 2015]



Sec. 123.23  Attorney General's statement.

    (a) Any State that seeks to administer a program under this part 
shall submit a statement from the State Attorney General (or the 
attorney for those State or interstate agencies which have independent 
legal counsel) that the laws of the State, or an interstate compact, 
provide adequate authority to carry out the program described under 
Sec. 123.22 and to meet the requirements of this part. This statement 
shall include citations to the specific statutes, administrative 
regulations, and, where appropriate, judicial decisions which 
demonstrate adequate authority. State statutes and regulations cited by 
the State Attorney General or independent legal counsel shall be in the 
form of lawfully adopted State statutes and regulations at the time the 
statement is signed and shall be fully effective by the time the program 
is approved. To qualify as ``independent legal counsel'' the attorney 
signing the statement required by this section must have full authority 
to independently represent the State agency in court on all matters 
pertaining to the State program.
    Note: EPA will supply States with an Attorney General's statement 
format on request.
    (b) If a State (which is not an Indian Tribe) seeks authority over 
activities on Indian lands, the statement shall contain an appropriate 
analysis of the State's authority.
    (c) The Attorney General's statement shall certify that the State 
has adequate legal authority to issue and enforce general permits if the 
State seeks to implement the general permit program under Sec. 122.28.

[48 FR 14178, Apr. 1, 1983, as amended at 58 FR 67981, Dec. 22, 1993]



Sec. 123.24  Memorandum of Agreement with the Regional Administrator.

    (a) Any State that seeks to administer a program under this part 
shall submit a Memorandum of Agreement. The Memorandum of Agreement 
shall be executed by the State Director and the Regional Administrator 
and shall become effective when approved by the Administrator. In 
addition to meeting the requirements of paragraph (b) of this section, 
the Memorandum of Agreement may include other terms, conditions, or 
agreements consistent with this part and relevant to the administration 
and enforcement of the State's regulatory program. The Administrator 
shall not approve any Memorandum of Agreement which contains provisions 
which restrict EPA's statutory oversight responsibility.
    (b) The Memorandum of Agreement shall include the following:
    (1)(i) Provisions for the prompt transfer from EPA to the State of 
pending permit applications and any other information relevant to 
program operation not already in the possession of the State Director 
(e.g., support files for permit issuance, compliance reports, etc.). If 
existing permits are transferred from EPA to the State for 
administration, the Memorandum of Agreement shall contain provisions 
specifying a procedure for transferring the administration of these 
permits. If a State lacks the authority to directly administer permits 
issued by the Federal government, a procedure may be

[[Page 297]]

established to transfer responsibility for these permits.
    Note: For example, EPA and the State and the permittee could agree 
that the State would issue a permit(s) identical to the outstanding 
Federal permit which would simultaneously be terminated.
    (ii) Where a State has been authorized by EPA to issue permits in 
accordance with Sec. 123.23(b) on the Federal Indian reservation of the 
Indian Tribe seeking program approval, provisions describing how the 
transfer of pending permit applications, permits, and any other 
information relevant to the program operation not already in the 
possession of the Indian Tribe (support files for permit issuance, 
compliance reports, etc.) will be accomplished.
    (2) Provisions specifying classes and categories of permit 
applications, draft permits, and proposed permits that the State will 
send to the Regional Administrator for review, comment and, where 
applicable, objection.
    (3) Provisions specifying the frequency and content of reports, 
documents and other information which the State is required to submit to 
EPA. The State shall allow EPA to routinely review State records, 
reports, and files relevant to the administration and enforcement of the 
approved program. State reports may be combined with grant reports where 
appropriate. These procedures must also implement the requirements of 40 
CFR 123.41(a) and 123.43 and 40 CFR part 127 (including the required 
data elements in appendix A to part 127).
    (4) Provisions on the State's compliance monitoring and enforcement 
program, including:
    (i) Provisions for coordination of compliance monitoring activities 
by the State and by EPA. These may specify the basis on which the 
Regional Administrator will select facilities or activities within the 
State for EPA inspection. The Regional Administrator will normally 
notify the State at least 7 days before any such inspection; and
    (ii) Procedures to assure coordination of enforcement activities.
    (5) When appropriate, provisions for joint processing of permits by 
the State and EPA for facilities or activities which require permits 
from both EPA and the State under different programs. (See Sec. 124.4.)
    Note: To promote efficiency and to avoid duplication and 
inconsistency, States are encouraged to enter into joint processing 
agreements with EPA for permit issuance. Likewise, States are encouraged 
(but not required) to consider steps to coordinate or consolidate their 
own permit programs and activities.
    (6) Provisions for modification of the Memorandum of Agreement in 
accordance with this part.
    (c) The Memorandum of Agreement, the annual program grant and the 
State/EPA Agreement should be consistent. If the State/EPA Agreement 
indicates that a change is needed in the Memorandum of Agreement, the 
Memorandum of Agreement may be amended through the procedures set forth 
in this part. The State/EPA Agreement may not override the Memorandum of 
Agreement.
    Note: Detailed program priorities and specific arrangements for EPA 
support of the State program will change and are therefore more 
appropriately negotiated in the context of annual agreements rather than 
in the MOA. However, it may still be appropriate to specify in the MOA 
the basis for such detailed agreements, e.g., a provision in the MOA 
specifying that EPA will select facilities in the State for inspection 
annually as part of the State/EPA agreement.
    (d) The Memorandum of Agreement shall also specify the extent to 
which EPA will waive its right to review, object to, or comment upon 
State-issued permits under section 402(d)(3), (e) or (f) of CWA. While 
the Regional Administrator and the State may agree to waive EPA review 
of certain ``classes or categories'' of permits, no waiver of review may 
be granted for the following classes or categories:
    (1) Discharges into the territorial sea;
    (2) Discharges which may affect the waters of a State other than the 
one in which the discharge originates;
    (3) Discharges proposed to be regulated by general permits (see 
Sec. 122.28);
    (4) Discharges from publicly owned treatment works with a daily 
average discharge exceeding 1 million gallons per day;
    (5) Discharges of uncontaminated cooling water with a daily average 
discharge exceeding 500 million gallons per day;
    (6) Discharges from any major discharger or from any discharger 
within

[[Page 298]]

any of the 21 industrial categories listed in appendix A to part 122;
    (7) Discharges from other sources with a daily average discharge 
exceeding 0.5 (one-half) million gallons per day, except that EPA review 
of permits for discharges of non-process wastewater may be waived 
regardless of flow.
    (e) Whenever a waiver is granted under paragraph (d) of this 
section, the Memorandum of Agreement shall contain:
    (1) A statement that the Regional Administrator retains the right to 
terminate the waiver as to future permit actions, in whole or in part, 
at any time by sending the State Director written notice of termination; 
and
    (2) A statement that the State shall supply EPA with copies of final 
permits.

40 CFR part 127 (NPDES Electronic Reporting Requirements).

    Note to paragraph (a):
    Except for paragraph (a)(46) of this section, States need not 
implement provisions identical to the above listed provisions. 
Implemented provisions must, however, establish requirements at least as 
stringent as the corresponding listed provisions. While States may 
impose more stringent requirements, they may not make one requirement 
more lenient as a tradeoff for making another requirement more 
stringent; for example, by requiring that public hearings be held prior 
to issuing any permit while reducing the amount of advance notice of 
such a hearing.
    State programs may, if they have adequate legal authority, implement 
any of the provisions of parts 122 and 124. See, for example, Sec. Sec. 
122.5(d) (continuation of permits) and 124.4 (consolidation of permit 
processing) of this chapter.
    For example, a State may impose more stringent requirements in an 
NPDES program by omitting the upset provision of Sec. 122.41 of this 
chapter or by requiring more prompt notice of an upset.

    (b) State NPDES programs shall have an approved continuing planning 
process under 40 CFR 130.5 and shall assure that the approved planning 
process is at all times consistent with the CWA.
    (c) State NPDES programs shall ensure that any board or body which 
approves all or portions of permits shall not include as a member any 
person who receives, or has during the previous 2 years received, a 
significant portion of income directly or indirectly from permit holders 
or applicants for a permit.
    (1) For the purposes of this paragraph:
    (i) Board or body includes any individual, including the Director, 
who has or shares authority to approve all or portions of permits either 
in the first instance, as modified or reissued, or on appeal.
    (ii) Significant portion of income means 10 percent or more of gross 
personal income for a calendar year, except that it means 50 percent or 
more of gross personal income for a calendar year if the recipient is 
over 60 years of age and is receiving that portion under retirement, 
pension, or similar arrangement.
    (iii) Permit holders or applicants for a permit does not include any 
department or agency of a State government, such as a Department of 
Parks or a Department of Fish and Wildlife.
    (iv) Income includes retirement benefits, consultant fees, and stock 
dividends.
    (2) For the purposes of paragraph (c) of this section, income is not 
received ``directly or indirectly from permit holders or applicants for 
a permit'' when it is derived from mutual fund payments, or from other 
diversified investments for which the recipient does not know the 
identity of the primary sources of income.

Sec. 123.26  Requirements for compliance evaluation programs.

    (a) State programs shall have procedures for receipt, evaluation, 
retention and investigation for possible enforcement of all notices and 
reports required of permittees and other regulated persons (and for 
investigation for possible enforcement of failure to submit these 
notices and reports).
    (b) State programs shall have inspection and surveillance procedures 
to determine, independent of information supplied by regulated persons, 
compliance or noncompliance with applicable program requirements. The 
State shall implement and maintain:
    (1) An automated, computerized system which is capable of 
identifying and tracking all facilities and activities

[[Page 300]]

subject to the State Director's authority and any instances of 
noncompliance with permit or other program requirements (e.g., 
identifying noncompliance with an automated, computerized program to 
compare permit limits to reported measurements). State programs must 
maintain a management information system which supports the compliance 
evaluation activities of this part (e.g., source inventories; compliance 
determinations based upon discharge monitoring reports, other submitted 
reports, and determinations of noncompliance made from inspection or 
document reviews; and subsequent violation notices, enforcement actions, 
orders, and penalties) and complies with 40 CFR part 3 (Cross-Media 
Electronic Reporting Regulation) and 40 CFR part 127 (NPDES Electronic 
Reporting Requirements). State programs may use EPA's national NPDES 
data system for their automated, computerized system;
    (2) A program for periodic inspections of the facilities and 
activities subject to regulation. These inspections shall be conducted 
in a manner designed to:
    (i) Determine compliance or noncompliance with issued permit 
conditions and other program requirements;
    (ii) Verify the accuracy of information submitted by permittees and 
other regulated persons in reporting forms and other forms supplying 
monitoring data;
    (iii) Verify the adequacy of sampling, monitoring, and other methods 
used by permittees and other regulated persons to develop that 
information; and
    (iv) Protect surface waters and public health.
    (3) A program for investigating information obtained regarding 
violations of applicable program and permit requirements; and
    (4) Procedures for receiving and ensuring proper consideration of 
information submitted by the Public about violations. Public effort in 
reporting violations shall be encouraged, and the State Director shall 
make available information on reporting procedures.
    (c) The State Director and State officers engaged in compliance 
evaluation shall have authority to enter any site or premises subject to 
regulation or in which records relevant to program operation are kept in 
order to copy any records, inspect, monitor or otherwise investigate 
compliance with the State program including compliance with permit 
conditions and other program requirements. States whose law requires a 
search warrant before entry conform with this requirement.
    (d) Investigatory inspections shall be conducted, samples shall be 
taken and other information shall be gathered in a manner (e.g., using 
proper ``chain of custody'' procedures) that will produce evidence 
admissible in an enforcement proceeding or in court.
    (e) State NPDES compliance evaluation programs shall have procedures 
and ability for:
    (1) Maintaining an automated, computerized system which is capable 
of managing the comprehensive electronic inventory of all sources 
covered by NPDES permits and generating an electronic schedule of 
reports required to be submitted by permittees to the State agency. 
(Note: State programs may use EPA's national NPDES data system for their 
automated, computerized system.);
    (2) Initial screening (i.e., pre-enforcement evaluation) of all 
permit or grant-related compliance information to identify violations 
and to establish priorities for further substantive technical 
evaluation;
    (3) When warranted, conducting a substantive technical evaluation 
following the initial screening of all permit or grant-related 
compliance information to determine the appropriate agency response;
    (4) Maintaining a management information system which supports the 
compliance evaluation activities of this part; and
    (5) Inspecting the facilities of all major dischargers at least 
annually.
    (f) A state, tribe, or territory that is designated by EPA as an 
initial recipient of electronic NPDES information, as defined in Sec. 
127.2 of this chapter, must maintain the data it collects and 
electronically transfer the minimum set of NPDES data to EPA through 
timely data transfers in compliance with all requirements of 40 CFR 
parts 3 and 127 (including the required data elements in appendix A to 
part 127). Timely means that the authorized state, tribe, or territory 
submits these

[[Page 301]]

data transfers (see the data elements in appendix A to 40 CFR part 127) 
to EPA within 40 days of when the state, tribe, or territory completed 
the activity or received a report submitted by a regulated entity. For 
example, the data regarding a state inspection of an NPDES-regulated 
entity that is finalized by the state on October 5th must be 
electronically transferred to EPA no later than November 14th of that 
same year (e.g., 40 days after October 5th). EPA must become the initial 
recipient of electronic NPDES information from NPDES-regulated entities 
if the state, tribe, or territory does not consistently maintain these 
timely data transfers or does not comply with 40 CFR parts 3 and 127. 
See 40 CFR 127.2(b) and 127.27 regarding the initial recipient.

Sec. 123.27  Requirements for enforcement authority.

    (a) Any State agency administering a program shall have available 
the following remedies for violations of State program requirements:
    (1) To restrain immediately and effectively any person by order or 
by suit in State court from engaging in any unauthorized activity which 
is endangering or causing damage to public health or the environment;
    Note: This paragraph (a)(1) requires that States have a mechanism 
(e.g., an administrative cease and desist order or the ability to seek a 
temporary restraining order) to stop any unauthorized activity 
endangering public health or the environment.
    (2) To sue in courts of competent jurisdiction to enjoin any 
threatened or continuing violation of any program requirement, including 
permit conditions, without the necessity of a prior revocation of the 
permit;
    (3) To assess or sue to recover in court civil penalties and to seek 
criminal remedies, including fines, as follows:
    (i) Civil penalties shall be recoverable for the violation of any 
NPDES permit condition; any NPDES filing requirement; any duty to allow 
or carry out inspection, entry or monitoring activities; or, any 
regulation or orders issued by the State Director. These penalties shall 
be assessable in at least the amount of $5,000 a day for each violation.
    (ii) Criminal fines shall be recoverable against any person who 
willfully or negligently violates any applicable standards or 
limitations; any NPDES permit condition; or any NPDES filing 
requirement. These fines shall be assessable in at least the amount of 
$10,000 a day for each violation.
    Note: States which provide the criminal remedies based on ``criminal 
negligence,'' ``gross negligence'' or strict liability satisfy the 
requirement of paragraph (a)(3)(ii) of this section.
    (iii) Criminal fines shall be recoverable against any person who 
knowingly makes any false statement, representation or certification in 
any NPDES form, in any notice or report required by an NPDES permit, or 
who knowingly renders inaccurate any monitoring device or method 
required to be maintained by the Director. These fines shall be 
recoverable in at least the amount of $5,000 for each instance of 
violation.
    Note: In many States the State Director will be represented in State 
courts by the State Attorney General or other appropriate legal officer. 
Although the State Director need not appear in court actions he or she 
should have power to request that any of the above actions be brought.
    (b)(1) The maximum civil penalty or criminal fine (as provided in 
paragraph (a)(3) of this section) shall be assessable for each instance 
of violation and, if the violation is continuous, shall be assessable up 
to the maximum amount for each day of violation.
    (2) The burden of proof and degree of knowledge or intent required 
under State law for establishing violations under paragraph (a)(3) of 
this section, shall be no greater than the burden of proof or degree of 
knowledge or intent EPA must provide when it brings an action under the 
appropriate Act;
    Note: For example, this requirement is not met if State law includes 
mental state as an element of proof for civil violations.
    (c) A civil penalty assessed, sought, or agreed upon by the State 
Director under paragraph (a)(3) of this section shall be appropriate to 
the violation.
    Note: To the extent that State judgments or settlements provide 
penalties in amounts which EPA believes to be substantially inadequate 
in comparison to the amounts which

[[Page 302]]

EPA would require under similar facts, EPA, when authorized by the 
applicable statute, may commence separate actions for penalties.
    Procedures for assessment by the State of the cost of 
investigations, inspections, or monitoring surveys which lead to the 
establishment of violations;
    In addition to the requirements of this paragraph, the State may 
have other enforcement remedies. The following enforcement options, 
while not mandatory, are highly recommended:
    Procedures which enable the State to assess or to sue any persons 
responsible for unauthorized activities for any expenses incurred by the 
State in removing, correcting, or terminating any adverse effects upon 
human health and the environment resulting from the unauthorized 
activity, whether or not accidental;
    Procedures which enable the State to sue for compensation for any 
loss or destruction of wildlife, fish or aquatic life, or their habitat, 
and for any other damages caused by unauthorized activity, either to the 
State or to any residents of the State who are directly aggrieved by the 
unauthorized activity, or both; and
    Procedures for the administrative assessment of penalties by the 
Director.
    (d) Any State administering a program shall provide for public 
participation in the State enforcement process by providing either:
    (1) Authority which allows intervention as of right in any civil or 
administrative action to obtain remedies specified in paragraphs (a)(1), 
(2) or (3) of this section by any citizen having an interest which is or 
may be adversely affected; or
    (2) Assurance that the State agency or enforcement authority will:
    (i) Investigate and provide written responses to all citizen 
complaints submitted pursuant to the procedures specified in Sec. 
123.26(b)(4);
    (ii) Not oppose intervention by any citizen when permissive 
intervention may be authorized by statute, rule, or regulation; and
    (iii) Publish notice of and provide at least 30 days for public 
comment on any proposed settlement of a State enforcement action.
    (e) Indian Tribes that cannot satisfy the criminal enforcement 
authority requirements of this section may still receive program 
approval if they meet the requirement for enforcement authority 
established under Sec. 123.34.

Sec. 123.28  Control of disposal of pollutants into wells.

    State law must provide authority to issue permits to control the 
disposal of pollutants into wells. Such authority shall enable the State 
to protect the public health and welfare and to prevent the pollution of 
ground and surface waters by prohibiting well discharges or by issuing 
permits for such discharges with appropriate permit terms and 
conditions. A program approved under section 1422 of SDWA satisfies the 
requirements of this section.
    Note: States which are authorized to administer the NPDES permit 
program under section 402 of CWA are encouraged to rely on existing 
statutory authority, to the extent possible, in developing a State UIC 
program under section 1422 of SDWA. Section 402(b)(1)(D) of CWA requires 
that NPDES States have the authority ``to issue permits which * * * 
control the disposal of pollutants into wells.'' In many instances, 
therefore, NPDES States will have existing statutory authority to 
regulate well disposal which satisfies the requirements of the UIC 
program. Note, however, that CWA excludes certain types of well 
injections from the definition of ``pollutant.'' If the State's 
statutory authority contains a similar exclusion it may need to be 
modified to qualify for UIC program approval.



Sec. 123.29  Prohibition.

    State permit programs shall provide that no permit shall be issued 
when the Regional Administrator has objected in writing under Sec. 
123.44.



Sec. 123.30  Judicial review of approval or denial of permits.

    All States that administer or seek to administer a program under 
this part shall provide an opportunity for judicial review in State 
Court of the final approval or denial of permits by the State that is 
sufficient to provide for,

[[Page 303]]

encourage, and assist public participation in the permitting process. A 
State will meet this standard if State law allows an opportunity for 
judicial review that is the same as that available to obtain judicial 
review in federal court of a federally-issued NPDES permit (see Sec. 
509 of the Clean Water Act). A State will not meet this standard if it 
narrowly restricts the class of persons who may challenge the approval 
or denial of permits (for example, if only the permittee can obtain 
judicial review, if persons must demonstrate injury to a pecuniary 
interest in order to obtain judicial review, or if persons must have a 
property interest in close proximity to a discharge or surface waters in 
order to obtain judicial review.) This requirement does not apply to 
Indian Tribes.

[61 FR 20980, May 8, 1996]



Sec. 123.31  Requirements for eligibility of Indian Tribes.

    (a) Consistent with section 518(e) of the CWA, 33 U.S.C. 1377(e), 
the Regional Administrator will treat an Indian Tribe as eligible to 
apply for NPDES program authority if it meets the following criteria:
    (1) The Indian Tribe is recognized by the Secretary of the Interior.
    (2) The Indian Tribe has a governing body carrying out substantial 
governmental duties and powers.
    (3) The functions to be exercised by the Indian Tribe pertain to the 
management and protection of water resources which are held by an Indian 
Tribe, held by the United States in trust for the Indians, held by a 
member of an Indian Tribe if such property interest is subject to a 
trust restriction on alienation, or otherwise within the borders of an 
Indian reservation.
    (4) The Indian Tribe is reasonably expected to be capable, in the 
Regional Administrator's judgment, of carrying out the functions to be 
exercised, in a manner consistent with the terms and purposes of the Act 
and applicable regulations, of an effective NPDES permit program.
    (b) An Indian Tribe which the Regional Administrator determines 
meets the criteria described in paragraph (a) of this section must also 
satisfy the State program requirements described in this part for 
assumption of the State program.

[58 FR 67981, Dec. 22, 1993, as amended at 59 FR 64343, Dec. 14, 1994]



Sec. 123.32  Request by an Indian Tribe for a determination 
of eligibility.

    An Indian Tribe may apply to the Regional Administrator for a 
determination that it qualifies pursuant to section 518 of the Act for 
purposes of seeking NPDES permit program approval. The application shall 
be concise and describe how the Indian Tribe will meet each of the 
requirements of Sec. 123.31. The application shall include the 
following information:
    (a) A statement that the Tribe is recognized by the Secretary of the 
Interior;
    (b) A descriptive statement demonstrating that the Tribal governing 
body is currently carrying out substantial governmental duties and 
powers over a defined area. This statement should:
    (1) Describe the form of the Tribal government;
    (2) Describe the types of governmental functions currently performed 
by the Tribal governing body, such as, but not limited to, the exercise 
of police powers affecting (or relating to) the health, safety, and 
welfare of the affected population; taxation; and the exercise of the 
power of eminent domain; and
    (3) Identify the source of the Tribal government's authority to 
carry out the governmental functions currently being performed.
    (c) A map or legal description of the area over which the Indian 
Tribe asserts authority under section 518(e)(2) of the Act; a statement 
by the Tribal Attorney General (or equivalent official authorized to 
represent the Tribe in all legal matters in court pertaining to the 
program for which it seeks approval) which describes the basis for the 
Tribe's assertion (including the nature or subject matter of the 
asserted regulatory authority); copies of those documents such as Tribal 
constitutions, by-laws, charters, executive orders, codes, ordinances, 
and/or resolutions which support the Tribe believes

[[Page 304]]

are relevant to its assertion under section 518(e)(2) of the Act; and a 
description of the location of the surface waters for which the Tribe 
proposes to establish an NPDES permit program.
    (d) A narrative statement describing the capability of the Indian 
Tribe to administer an effective, environmentally sound NPDES permit 
program. The statement should include:
    (1) A description of the Indian Tribe's previous management 
experience which may include the administration of programs and service 
authorized by the Indian Self-Determination and Education Assistance Act 
(25 U.S.C. 450 et seq.), the Indian Mineral Development Act (25 U.S.C. 
2101 et seq.), or the Indian Sanitation Facility Construction Activity 
Act (42 U.S.C. 2004a);
    (2) A list of existing environmental or public health programs 
administered by the Tribal governing body, and a copy of related Tribal 
laws, regulations, and policies;
    (3) A description of the entity (or entities) which exercise the 
executive, legislative, and judicial functions of the Tribal government;
    (4) A description of the existing, or proposed, agency of the Indian 
Tribe which will assume primary responsibility for establishing and 
administering an NPDES permit program (including a description of the 
relationship between the existing or proposed agency and its regulated 
entities);
    (5) A description of the technical and administrative abilities of 
the staff to administer and manage an effective, environmentally sound 
NPDES permit program or a plan which proposes how the Tribe will acquire 
additional administrative and technical expertise. The plan must address 
how the Tribe will obtain the funds to acquire the administrative and 
technical expertise.
    (e) The Regional Administrator may, at his or her discretion, 
request further documentation necessary to support a Tribe's 
eligibility.
    (f) If the Administrator or his or her delegatee has previously 
determined that a Tribe has met the prerequisites that make it eligible 
to assume a role similar to that of a state as provided by statute under 
the Safe Drinking Water Act, the Clean Water Act, or the Clean Air Act, 
then that Tribe need provide only that information unique to the NPDES 
program which is requested by the Regional Administrator.

Sec. 123.33  Procedures for processing an Indian Tribe's application.

    (a) The Regional Administrator shall process an application of an 
Indian Tribe submitted pursuant to Sec. 123.32 in a timely manner. He 
shall promptly notify the Indian Tribe of receipt of the application.
    (b) The Regional Administrator shall follow the procedures described 
in 40 CFR part 123, subpart D in processing a Tribe's request to assume 
the NPDES program.

Sec. 123.34  Provisions for Tribal criminal enforcement authority.

    To the extent that an Indian Tribe is precluded from asserting 
criminal enforcement authority as required under Sec. 123.27, the 
Federal Government will exercise primary criminal enforcement 
responsibility. The Tribe, with the EPA Region, shall develop a 
procedure by which the Tribal agency will refer potential criminal 
violations to the Regional Administrator, as agreed to by the parties, 
in an appropriate and timely manner. This procedure shall encompass all 
circumstances in which the Tribe is incapable of exercising the 
enforcement requirements of Sec. 123.27. This agreement shall be 
incorporated into a joint or separate Memorandum of Agreement with the 
EPA Region, as appropriate.

[58 FR 67983, Dec. 22, 1993]



Sec. 123.35  As the NPDES Permitting Authority for regulated small
MS4s, what is my role?

    (a) You must comply with the requirements for all NPDES permitting 
authorities under Parts 122, 123, 124, and 125 of this chapter. (This 
section is meant only to supplement those requirements and discuss 
specific issues related to the small MS4 storm water program.)

[[Page 305]]

    (b) You must develop a process, as well as criteria, to designate 
small MS4s other than those described in Sec. 122.32(a)(1) of this 
chapter, as regulated small MS4s to be covered under the NPDES storm 
water discharge control program. This process must include the authority 
to designate a small MS4 waived under paragraph (d) of this section if 
circumstances change. EPA may make designations under this section if a 
State or Tribe fails to comply with the requirements listed in this 
paragraph. In making designations of small MS4s, you must:
    (1)(i) Develop criteria to evaluate whether a storm water discharge 
results in or has the potential to result in exceedances of water 
quality standards, including impairment of designated uses, or other 
significant water quality impacts, including habitat and biological 
impacts.
    (ii) Guidance: For determining other significant water quality 
impacts, EPA recommends a balanced consideration of the following 
designation criteria on a watershed or other local basis: discharge to 
sensitive waters, high growth or growth potential, high population 
density, contiguity to an urbanized area, significant contributor of 
pollutants to waters of the United States, and ineffective protection of 
water quality by other programs;
    (2) Apply such criteria, at a minimum, to any small MS4 located 
outside of an urbanized area serving a jurisdiction with a population 
density of at least 1,000 people per square mile and a population of at 
least 10,000;
    (3) Designate any small MS4 that meets your criteria by December 9, 
2002. You may wait until December 8, 2004 to apply the designation 
criteria on a watershed basis if you have developed a comprehensive 
watershed plan. You may apply these criteria to make additional 
designations at any time, as appropriate; and
    (4) Designate any small MS4 that contributes substantially to the 
pollutant loadings of a physically interconnected municipal separate 
storm sewer that is regulated by the NPDES storm water program.
    (c) You must make a final determination within 180 days from receipt 
of a petition under Sec. 122.26(f) of this chapter (or analogous State 
or Tribal law). If you do not do so within that time period, EPA may 
make a determination on the petition.
    (d) You must issue permits consistent with Sec. Sec. 122.32 through 
122.35 of this chapter to all regulated small MS4s. You may waive or 
phase in the requirements otherwise applicable to regulated small MS4s, 
as defined in Sec. 122.32(a)(1) of this chapter, under the following 
circumstances:
    (1) You may waive permit coverage for each small MS4s in 
jurisdictions with a population under 1,000 within the urbanized area 
where all of the following criteria have been met:
    (i) Its discharges are not contributing substantially to the 
pollutant loadings of a physically interconnected regulated MS4 (see 
paragraph (b)(4) of this section); and
    (ii) If the small MS4 discharges any pollutant(s) that have been 
identified as a cause of impairment of any water body to which it 
discharges, storm water controls are not needed based on wasteload 
allocations that are part of an EPA approved or established ``total 
maximum daily load'' (TMDL) that address the pollutant(s) of concern.
    (2) You may waive permit coverage for each small MS4 in 
jurisdictions with a population under 10,000 where all of the following 
criteria have been met:
    (i) You have evaluated all waters of the U.S., including small 
streams, tributaries, lakes, and ponds, that receive a discharge from 
the MS4 eligible for such a waiver.
    (ii) For all such waters, you have determined that storm water 
controls are not needed based on wasteload allocations that are part of 
an EPA approved or established TMDL that addresses the pollutant(s) of 
concern or, if a TMDL has not been developed or approved, an equivalent 
analysis that determines sources and allocations for the pollutant(s) of 
concern.
    (iii) For the purpose of paragraph (d)(2)(ii) of this section, the 
pollutant(s) of concern include biochemical oxygen demand (BOD), 
sediment or a parameter that addresses sediment (such as total suspended 
solids, turbidity or siltation), pathogens, oil and grease, and any 
pollutant that has been

[[Page 306]]

identified as a cause of impairment of any water body that will receive 
a discharge from the MS4.
    (iv) You have determined that current and future discharges from the 
MS4 do not have the potential to result in exceedances of water quality 
standards, including impairment of designated uses, or other significant 
water quality impacts, including habitat and biological impacts.
    (v) Guidance: To help determine other significant water quality 
impacts, EPA recommends a balanced consideration of the following 
criteria on a watershed or other local basis: discharge to sensitive 
waters, high growth or growth potential, high population or commercial 
density, significant contributor of pollutants to waters of the United 
States, and ineffective protection of water quality by other programs.
    (3) You may phase in permit coverage for small MS4s serving 
jurisdictions with a population under 10,000 on a schedule consistent 
with a State watershed permitting approach. Under this approach, you 
must develop and implement a schedule to phase in permit coverage for 
approximately 20 percent annually of all small MS4s that qualify for 
such phased-in coverage. Under this option, all regulated small MS4s are 
required to have coverage under an NPDES permit by no later than March 
8, 2007. Your schedule for phasing in permit coverage for small MS4s 
must be approved by the Regional Administrator no later than December 
10, 2001.
    (4) If you choose to phase in permit coverage for small MS4s in 
jurisdictions with a population under 10,000, in accordance with 
paragraph (d)(3) of this section, you may also provide waivers in 
accordance with paragraphs (d)(1) and (d)(2) of this section pursuant to 
your approved schedule.
    (5) If you do not have an approved schedule for phasing in permit 
coverage, you must make a determination whether to issue an NPDES permit 
or allow a waiver in accordance with paragraph (d)(1) or (d)(2) of this 
section, for each eligible MS4 by December 9, 2002.
    (6) You must periodically review any waivers granted in accordance 
with paragraph (d)(2) of this section to determine whether any of the 
information required for granting the waiver has changed. At a minimum, 
you must conduct such a review once every five years. In addition, you 
must consider any petition to review any waiver when the petitioner 
provides evidence that the information required for granting the waiver 
has substantially changed.
    (e) You must specify a time period of up to 5 years from the date of 
permit issuance for operators of regulated small MS4s to fully develop 
and implement their storm water program.
    (f) You must include the requirements in Sec. Sec. 122.33 through 
122.35 of this chapter in any permit issued for regulated small MS4s or 
develop permit limits based on a permit application submitted by a 
regulated small MS4. (You may include conditions in a regulated small 
MS4 NPDES permit that direct the MS4 to follow an existing qualifying 
local program's requirements, as a way of complying with some or all of 
the requirements in Sec. 122.34(b) of this chapter. See Sec. 122.34(c) 
of this chapter. Qualifying local, State or Tribal program requirements 
must impose, at a minimum, the relevant requirements of Sec. 122.34(b) 
of this chapter.)
    (g) If you issue a general permit to authorize storm water 
discharges from small MS4s, you must make available a menu of BMPs to 
assist regulated small MS4s in the design and implementation of 
municipal storm water management programs to implement the minimum 
measures specified in Sec. 122.34(b) of this chapter. EPA plans to 
develop a menu of BMPs that will apply in each State or Tribe that has 
not developed its own menu. Regardless of whether a menu of BMPs has 
been developed by EPA, EPA encourages State and Tribal permitting 
authorities to develop a menu of BMPs that is appropriate for local 
conditions. EPA also intends to provide guidance on developing BMPs and 
measurable goals and modify, update, and supplement such guidance based 
on the assessments of the NPDES MS4 storm water program and research to 
be conducted over the next thirteen years.
    (h)(1) You must incorporate any additional measures necessary to 
ensure effective implementation of your State

[[Page 307]]

or Tribal storm water program for regulated small MS4s.
    (2) Guidance: EPA recommends consideration of the following:
    (i) You are encouraged to use a general permit for regulated small 
MS4s;
    (ii) To the extent that your State or Tribe administers a dedicated 
funding source, you should play an active role in providing financial 
assistance to operators of regulated small MS4s;
    (iii) You should support local programs by providing technical and 
programmatic assistance, conducting research projects, performing 
watershed monitoring, and providing adequate legal authority at the 
local level;
    (iv) You are encouraged to coordinate and utilize the data collected 
under several programs including water quality management programs, TMDL 
programs, and water quality monitoring programs;
    (v) Where appropriate, you may recognize existing responsibilities 
among governmental entities for the control measures in an NPDES small 
MS4 permit (see Sec. 122.35(b) of this chapter); and
    (vi) You are encouraged to provide a brief (e.g., two page) 
reporting format to facilitate compiling and analyzing data from 
submitted reports under Sec. 122.34(g)(3) of this chapter. EPA intends 
to develop a model form for this purpose.

Sec. 123.36  Establishment of technical standards for concentrated
animal feeding operations.

    If the State has not already established technical standards for 
nutrient management that are consistent with 40 CFR 412.4(c)(2), the 
Director shall establish such standards by the date specified in Sec. 
123.62(e).

           Subpart C_Transfer of Information and Permit Review



Sec. 123.41  Sharing of information.

    (a) Any information obtained or used in the administration of a 
State program shall be available to EPA upon request without 
restriction. This includes the timely data transfers in compliance with 
all requirements of 40 CFR parts 3 and 127 (including the required data 
elements in appendix A to part 127). If the information has been 
submitted to the State under a claim of confidentiality, the State must 
submit that claim to EPA when providing information under this section. 
Any information obtained from a State and subject to a claim of 
confidentiality will be treated in compliance with the regulations in 40 
CFR part 2. If EPA obtains information from an authorized state NPDES 
program, which is not claimed to be confidential, EPA may make that 
information available to the public without further notice. Timely means 
that the authorized state, tribe, or territory submits these data 
transfers (see the data elements in appendix A to 40 CFR part 127) to 
EPA within 40 days of when the state, tribe, or territory completed the 
activity or received a report submitted by a regulated entity. For 
example, the data regarding a state inspection of an NPDES-regulated 
entity that is finalized by the state on October 5th must be 
electronically transferred to EPA no later than November 14th of that 
same year (e.g., 40 days after October 5th). EPA must become the initial 
recipient of electronic NPDES information from NPDES-regulated entities 
if the state, tribe, or territory does not consistently maintain these 
timely data transfers or does not comply with 40 CFR parts 3 and 127. 
See 40 CFR 127.2(b) and 127.27 regarding the initial recipient.
    (b) EPA shall furnish to States with approved programs the 
information in its files not submitted under a claim of confidentiality 
which the State needs to implement its approved program. EPA shall 
furnish to States with approved programs information submitted to EPA 
under a claim of confidentiality, which the State needs to implement its 
approved program, subject to the conditions in 40 CFR part 2.

Sec. 123.42  Receipt and use of Federal information.

    Upon approving a State permit program, EPA will send to the State 
agency administering the permit program any relevant information which 
was

[[Page 308]]

collected by EPA. The Memorandum of Agreement under Sec. 123.24 (or, in 
the case of a sewage sludge management program, Sec. 501.14 of this 
chapter) will provide for the following, in such manner as the State 
Director and the Regional Administrator agree:
    (a) Prompt transmission to the State Director from the Regional 
Administrator of copies of any pending permit applications or any other 
relevant information collected before the approval of the State permit 
program and not already in the possession of the State Director. When 
existing permits are transferred to the State Director (e.g., for 
purposes of compliance monitoring, enforcement or reissuance), relevant 
information includes support files for permit issuance, compliance 
reports and records of enforcement actions.
    (b) Procedures to ensure that the State Director will not issue a 
permit on the basis of any application received from the Regional 
Administrator which the Regional Administrator identifies as incomplete 
or otherwise deficient until the State Director receives information 
sufficient to correct the deficiency.

[48 FR 14178, Apr. 1, 1983, as amended at 63 FR 45122, Aug. 24, 1998]



Sec. 123.43  Transmission of information to EPA.

    (a) Each State agency administering a permit program shall transmit 
to the Regional Administrator copies of permit program forms and any 
other relevant information to the extent and in the manner agreed to by 
the State Director and Regional Administrator in the Memorandum of 
Agreement and not inconsistent with this part. Proposed permits shall be 
prepared by State agencies unless agreement to the contrary has been 
reached under Sec. 123.44(j). The Memorandum of Agreement shall provide 
for the following:
    (1) Prompt transmission to the Regional Administrator of a copy of 
all complete permit applications received by the State Director, except 
those for which permit review has been waived under Sec. 123.24(d). The 
State shall supply EPA with copies of permit applications for which 
permit review has been waived whenever requested by EPA;
    (2) Prompt transmission to the Regional Administrator of notice of 
every action taken by the State agency related to the consideration of 
any permit application or general permit, including a copy of each 
proposed or draft permit and any conditions, requirements, or documents 
which are related to the proposed or draft permit or which affect the 
authorization of the proposed permit, except those for which permit 
review has been waived under Sec. 123.24(d). The State shall supply EPA 
with copies of notices for which permit review has been waived whenever 
requested by EPA; and
    (3) Transmission to the Regional Administrator of a copy of every 
issued permit following issuance, along with any and all conditions, 
requirements, or documents which are related to or affect the 
authorization of the permit.
    (b) If the State intends to waive any of the permit application 
requirements of Sec. 122.21(j) or (q) of this chapter for a specific 
applicant, the Director must submit a written request to the Regional 
Administrator no less than 210 days prior to permit expiration. This 
request must include the State's justification for granting the waiver.
    (c) The State program shall provide for transmission by the State 
Director to EPA of:
    (1) Notices from publicly owned treatment works under Sec. 
122.42(b) and 40 CFR part 403, upon request of the Regional 
Administrator;
    (2) A copy of any significant comments presented in writing pursuant 
to the public notice of a draft permit and a summary of any significant 
comments presented at any hearing on any draft permit, except those 
comments regarding permits for which permit review has been waived under 
Sec. 123.24(d) and for which EPA has not otherwise requested receipt, 
if:
    (i) The Regional Administrator requests this information; or
    (ii) The proposed permit contains requirements significantly 
different from those contained in the tentative determination and draft 
permit; or
    (iii) Significant comments objecting to the tentative determination 
and draft permit have been presented at the hearing or in writing 
pursuant to the public notice.

[[Page 309]]

    (d) Any State permit program shall keep such records and submit to 
the Administrator such information as the Administrator may reasonably 
require to ascertain whether the State program complies with the 
requirements of the CWA or of this part. This includes the timely data 
transfers in compliance with all requirements of 40 CFR part 127 
(including the required data elements in appendix A to part 127).

[48 FR 14178, Apr. 1, 1983, as amended at 60 FR 33931, June 29, 1995; 64 
FR 42470, Aug. 4, 1999; 80 FR 64100, Oct. 22, 2015]



Sec. 123.44  EPA review of and objections to State permits.

    (a)(1) The Memorandum of Agreement shall provide a period of time 
(up to 90 days from receipt of proposed permits) to which the Regional 
Administrator may make general comments upon, objections to, or 
recommendations with respect to proposed permits. EPA reserves the right 
to take 90 days to supply specific grounds for objection, 
notwithstanding any shorter period specified in the Memorandum of 
Agreement, when a general objection is filed within the review period 
specified in the Memorandum of Agreement. The Regional Administrator 
shall send a copy of any comment, objection or recommendation to the 
permit applicant.
    (2) In the case of general permits, EPA shall have 90 days from the 
date of receipt of the proposed general permit to comment upon, object 
to or make recommendations with respect to the proposed general permit, 
and is not bound by any shorter time limits set by the Memorandum of 
Agreement for general comments, objections or recommendations.
    (b)(1) Within the period of time provided under the Memorandum of 
Agreement for making general comments upon, objections to or 
recommendations with respect to proposed permits, the Regional 
Administrator shall notify the State Director of any objection to 
issuance of a proposed permit (except as provided in paragraph (a)(2) of 
this section for proposed general permits). This notification shall set 
forth in writing the general nature of the objection.
    (2) Within 90 days following receipt of a proposed permit to which 
he or she has objected under paragraph (b)(1) of this section, or in the 
case of general permits within 90 days after receipt of the proposed 
general permit, the Regional Administrator shall set forth in writing 
and transmit to the State Director:
    (i) A statement of the reasons for the objection (including the 
section of CWA or regulations that support the objection), and
    (ii) The actions that must be taken by the State Director to 
eliminate the objection (including the effluent limitations and 
conditions which the permit would include if it were issued by the 
Regional Administrator.)
    Note: Paragraphs (a) and (b) of this section, in effect, modify any 
existing agreement between EPA and the State which provides less than 90 
days for EPA to supply the specific grounds for an objection. However, 
when an agreement provides for an EPA review period of less than 90 
days, EPA must file a general objection, in accordance with paragraph 
(b)(1) of this section within the time specified in the agreement. This 
general objection must be followed by a specific objection within the 
90-day period. This modification to MOA's allows EPA to provide detailed 
information concerning acceptable permit conditions, as required by 
section 402(d) of CWA. To avoid possible confusion, MOA's should be 
changed to reflect this arrangement.
    (c) The Regional Administrator's objection to the issuance of a 
proposed permit must be based upon one or more of the following grounds:
    (1) The permit fails to apply, or to ensure compliance with, any 
applicable requirement of this part;
    Note: For example, the Regional Administrator may object to a permit 
not requiring the achievement of required effluent limitations by 
applicable statutory deadlines.
    (2) In the case of a proposed permit for which notification to the 
Administrator is required under section 402(b)(5) of CWA, the written 
recommendations of an affected State have not been accepted by the 
permitting State and the Regional Administrator finds the reasons for 
rejecting the recommendations are inadequate;

[[Page 310]]

    (3) The procedures followed in connection with formulation of the 
proposed permit failed in a material respect to comply with procedures 
required by CWA or by regulations thereunder or by the Memorandum of 
Agreement;
    (4) Any finding made by the State Director in connection with the 
proposed permit misinterprets CWA or any guidelines or regulations under 
CWA, or misapplies them to the facts;
    (5) Any provisions of the proposed permit relating to the 
maintenance of records, reporting, monitoring, sampling, or the 
provision of any other information by the permittee are inadequate, in 
the judgment of the Regional Administrator, to assure compliance with 
permit conditions, including effluent standards and limitations or 
standards for sewage sludge use and disposal required by CWA, by the 
guidelines and regulations issued under CWA, or by the proposed permit;
    (6) In the case of any proposed permit with respect to which 
applicable effluent standards and limitations or standards for sewage 
sludge use and disposal under sections 301, 302, 306, 307, 318, 403, and 
405 of CWA have not yet been promulgated by the Agency, the proposed 
permit, in the judgment of the Regional Administrator, fails to carry 
out the provisions of CWA or of any regulations issued under CWA; the 
provisions of this paragraph apply to determinations made pursuant to 
Sec. 125.3(c)(2) in the absence of applicable guidelines, to best 
management practices under section 304(e) of CWA, which must be 
incorporated into permits as requirements under section 301, 306, 307, 
318, 403 or 405, and to sewage sludge use and disposal requirements 
developed on a case-by-case basis pursuant to section 405(d) of CWA, as 
the case may be;
    (7) Issuance of the proposed permit would in any other respect be 
outside the requirements of CWA, or regulations issued under CWA.
    (8) The effluent limits of a permit fail to satisfy the requirements 
of 40 CFR 122.44(d).
    (9) For a permit issued by a Great Lakes State or Tribe (as defined 
in 40 CFR 132.2), the permit does not satisfy the conditions promulgated 
by the State, Tribe, or EPA pursuant to 40 CFR part 132.
    (d) Prior to notifying the State Director of an objection based upon 
any of the grounds set forth in paragraph (c) of this section, the 
Regional Administrator:
    (1) Will consider all data transmitted pursuant to Sec. 123.43 (or, 
in the case of a sewage sludge management program, Sec. 501.21 of this 
chapter);
    (2) May, if the information provided is inadequate to determine 
whether the proposed permit meets the guidelines and requirements of 
CWA, request the State Director to transmit to the Regional 
Administrator the complete record of the permit proceedings before the 
State, or any portions of the record that the Regional Administrator 
determines are necessary for review. If this request is made within 30 
days of receipt of the State submittal under Sec. 123.43 (or, in the 
case of a sewage sludge management program, Sec. 501.21 of this 
chapter), it will constitute an interim objection to the issuance of the 
permit, and the full period of time specified in the Memorandum of 
Agreement for the Regional Administrator's review will recommence when 
the Regional Administrator has received such record or portions of the 
record; and
    (3) May, in his or her discretion, and to the extent feasible within 
the period of time available under the Memorandum of Agreement, afford 
to interested persons an opportunity to comment on the basis for the 
objection;
    (e) Within 90 days of receipt by the State Director of an objection 
by the Regional Administrator, the State or interstate agency or any 
interested person may request that a public hearing be held by the 
Regional Administrator on the objection. A public hearing in accordance 
with the procedures of Sec. 124.12 (c) and (d) of this chapter (or, in 
the case of a sewage sludge management program, Sec. 501.15(d)(7) of 
this chapter) will be held, and public notice provided in accordance 
with Sec. 124.10 of this chapter, (or, in the case of a sewage sludge 
management program, Sec. 501.15(d)(5) of this chapter), whenever 
requested by the State or the interstate agency which proposed the 
permit or if warranted by significant public interest based on requests 
received.

[[Page 311]]

    (f) A public hearing held under paragraph (e) of this section shall 
be conducted by the Regional Administrator, and, at the Regional 
Administrator's discretion, with the assistance of an EPA panel 
designated by the Regional Administrator, in an orderly and expeditious 
manner.
    (g) Following the public hearing, the Regional Administrator shall 
reaffirm the original objection, modify the terms of the objection, or 
withdraw the objection, and shall notify the State of this decision.
    (h)(1) If no public hearing is held under paragraph (e) of this 
section and the State does not resubmit a permit revised to meet the 
Regional Administrator's objection within 90 days of receipt of the 
objection, the Regional Administrator may issue the permit in accordance 
with parts 121, 122 and 124 of this chapter and any other guidelines and 
requirements of CWA.
    (2) If a public hearing is held under paragraph (e) of this section, 
the Regional Administrator does not withdraw the objection, and the 
State does not resubmit a permit revised to meet the Regional 
Administrator's objection or modified objection within 30 days of the 
date of the Regional Administrator's notification under paragraph (g) of 
this section, the Regional Administrator may issue the permit in 
accordance with parts 121, 122 and 124 of this chapter and any other 
guidelines and requirements of CWA.
    (3) Exclusive authority to issue the permit passes to EPA when the 
times set out in this paragraph expire.
    (i) [Reserved]
    (j) The Regional Administrator may agree, in the Memorandum of 
Agreement under Sec. 123.24 (or, in the case of a sewage sludge 
management program, Sec. 501.14 of this chapter), to review draft 
permits rather than proposed permits. In such a case, a proposed permit 
need not be prepared by the State and transmitted to the Regional 
Administrator for review in accordance with this section unless the 
State proposes to issue a permit which differs from the draft permit 
reviewed by the Regional Administrator, the Regional Administrator has 
objected to the draft permit, or there is significant public comment.

Sec. 123.45  Noncompliance and program reporting by the Director.

    As of December 21, 2021 EPA must prepare public (quarterly and 
annual) reports as set forth here from information that is required to 
be submitted by NPDES-regulated facilities and the State Director.
    (a) NPDES noncompliance reports (NNCR)--quarterly. EPA must produce 
an online report on a quarterly basis with the minimum content specified 
here. The Director must electronically submit timely, accurate, and 
complete data to EPA that allows EPA to prepare these quarterly NNCRs.
    (1) Content. The NNCR must include the following information:
    (i) A facility specific list of NPDES-regulated entities in 
violation, including non-POTWs, POTWs, Federal permittees, major 
facilities, and nonmajor facilities, as well as a list of CWA point 
sources that did not obtain NPDES permits authorizing discharges of 
pollutants to waters of the United States.
    (ii) For each identified NPDES-regulated entity in violation of the 
Clean Water Act:
    (A) The name, location, and permit number or other identification 
number, if a permit does not exist.
    (B) Information describing identified violation(s) that occurred in 
that quarter, including the date(s) on which violation(s) started and 
ended (if applicable). Where applicable, the information must indicate 
the pipe, parameter, and the effluent limit(s) violated. Violations must 
be classified as Category I and II as described in paragraph (a)(2) of 
this section.
    (C) The date(s) and type of formal enforcement and written informal 
enforcement action(s) taken by the Director to respond to violation(s), 
including any penalties assessed.
    (D) The status of the violation(s) (e.g., corrected or continuing, 
and the date that the violation(s) was resolved), which can be reported 
by linking violations to specific enforcement

[[Page 312]]

actions, or tracking noncompliance end dates.
    (E) Any optional details that may help explain the instance(s) of 
noncompliance as provided by the Director or EPA.
    (F) All violations must be reported in successive quarterly reports 
until the violation(s) is documented as being corrected (i.e., the 
regulated entity is no longer in violation). After a violation is 
reported as corrected in the NNCR, that particular violation will not 
continue to appear in subsequent quarterly reports, although it will 
appear in the relevant annual report.
    (G) If the permittee or discharger is in compliance with an 
enforcement order (e.g., permittee is completing the necessary upgrades 
to its existing wastewater treatment system in accordance with the 
schedule in the enforcement order), and has no new, additional 
violation(s), the compliance status must be reported as ``resolved 
pending'' in the NNCR. The permittee/discharger will continue to be 
listed on the NNCR until the violation(s) is documented as being 
corrected.
    (2) Violation classifications. A violation must be classified as 
``Category I Noncompliance'' if one or more of the criteria set forth 
below are met.
    (i) Reporting violations. These include failure to submit a 
complete, required report (e.g., final compliance schedule progress 
report, discharge monitoring report, annual report) within 30 days after 
the date established in a permit, administrative or judicial order, or 
regulation. In addition, these also include any failure to comply with 
the reporting requirements at 40 CFR 122.41(l)(6).
    (ii) Compliance construction violations. These include failure to 
start construction, complete construction, or achieve final compliance 
within 90 days after the date established in a permit, administrative or 
judicial order, or regulation.
    (iii) Effluent limits. These include violations of interim or final 
effluent limits established in a permit, administrative or judicial 
enforcement order, or regulation that exceed the ``Criteria for 
Noncompliance Reporting in the NPDES Program'' in appendix A to Sec. 
123.45.
    (iv) Compliance schedule violations. These include violations of any 
requirement or condition in permits, or administrative or judicial 
enforcement orders, excluding reporting violations, compliance 
construction milestones and effluent limits.
    (v) Non-numeric effluent limit violations. These include violations 
of non-numeric effluent limits (e.g., violations of narrative permit 
requirements or requirements to implement best management practices) 
that caused or could cause water quality impacts. Examples of such 
impacts on water quality include, but are not limited to, unauthorized 
discharges that may have caused or contributed to exceedances in water 
quality standards, fish kills, oil sheens, beach closings, fishing bans, 
restrictions on designated uses, and unauthorized bypass or pass through 
or interference with the operations of a POTW (see 40 CFR 403.3).
    (vi) Other violations. These include any violation or group of 
violations, which in the discretion of the Director or EPA, are 
considered to be of concern. These violations include repeat violations 
by a specific point source, geographic clusters of violations, 
corporations with violations at multiple facilities, or industrial 
sectors with identified patterns of violation that have a cumulative 
impact on water quality, but otherwise would not meet Category I 
criteria. EPA must determine whether to issue policy or guidance to 
provide more specificity on identifying these types of violations and 
how to report them.
    (vii) All other types of noncompliance that do not meet the criteria 
for Category I Noncompliance must be classified as ``Category II 
Noncompliance.''
    (3) EPA must provide an easy-to-use interface to facilitate public 
access, use, and understanding of the NNCR, including the ability to 
sort violations by duration, severity, frequency, detection method 
(e.g., self-reported effluent, monitoring, inspection), flow and 
pollutant loadings, type of discharger, waterbody receiving the 
discharge, proximity to impaired waters, and category of violation (I or 
II). EPA must

[[Page 313]]

exclude from public release any confidential business information or 
enforcement-sensitive information associated with the NNCR.
    (b) NPDES noncompliance reports--annual summary (annual). EPA must 
prepare annual public reports that provide a summary of compliance 
monitoring and enforcement activities within each state, tribe, and 
territory, as well as summary information on violations identified in 
the four quarterly NNCRs for that federal fiscal year. EPA must provide 
these annual reports by no later than March 1st of the following year.
    (1) Facility types covered by reports. EPA must produce, at a 
minimum, Annual Summary Reports for the following universes: 
Individually-permitted NPDES-regulated entities; all other NPDES-
regulated entities that are not individually permitted; Clean Water Act 
point sources that had unauthorized discharge(s) of pollutants to waters 
of the US; and a combined report that includes totals across all three 
reports above. Individually-permitted facilities are defined in this 
subsection as those permits that are unique to the permittee, that 
include permitted effluent limits, and require the submission of 
discharge monitoring reports.
    (2) Content of reports. Reports must include applicable data for 
NPDES-regulated entities:
    (i) The number of NPDES permittees;
    (ii) The number inspected by on-site inspections;
    (iii) The number reviewed in which permitted limits were compared to 
measured data to determine violations;
    (iv) The number evaluated by other, off-site compliance monitoring 
activities;
    (v) The number with any violations;
    (vi) The number with Category I violations;
    (vii) The number receiving paper or electronic written informal 
enforcement actions;
    (viii) The total number receiving formal enforcement actions with a 
compliance schedule;
    (ix) The total number receiving a penalty assessment;
    (x) The total amount of penalties assessed; and
    (xi) The number of permit modifications extending compliance 
deadlines more than one year.
    (c) Schedule for producing NNCR quarterly information. (1) The 
Director has until 45 days from the end of the calendar quarter to 
update or correct NPDES data submissions in EPA's national NPDES data 
system for events that occurred within that calendar quarter covered by 
the NNCR.
    (2) EPA must publish the NNCR in electronic form to be easily 
accessible and available to the public within two months after the end 
date of the calendar quarter:

   Appendix A to Sec. 123.45--Criteria for Category I Noncompliance 
                     Reporting in the NPDES Program

    This appendix describes the criteria for reporting Category I 
violations of NPDES permit effluent limits in the NPDES non-compliance 
report (NNCR) as specified under paragraph (a)(2)(C) of this section. 
Any violation of an NPDES permit is a violation of the Clean Water Act 
(CWA) for which the permittee is liable. As specified in paragraph 
(a)(2) of this section, there are two categories of noncompliance, and 
the table below indicates the thresholds for violations in Category I. 
An agency's decision as to what enforcement action, if any, should be 
taken in such cases, shall be based on an analysis of facts, legal 
requirements, policy, and guidance.

                  Violations of Permit Effluent Limits

    The categorization of permit effluent limits depends upon the 
magnitude and/or frequency of the violation. Effluent violations shall 
be evaluated on a parameter-by-parameter and outfall-by-outfall basis. 
The criteria for reporting effluent violations are as follows:

   a. Reporting Criteria for Category I Violations of Monthly Average 
                 Permit Limits--Magnitude and Frequency

    Violations of monthly average effluent limits which exceed or equal 
the product of

[[Page 314]]

the Technical Review Criteria (TRC) times the effluent limit, and occur 
two months in a six- month period must be reported. TRCs are for two 
groups of pollutants.

Group I Pollutants--TRC=1.4
Group II Pollutants--TRC=1.2

 b. Reporting Criteria for Chronic Violations of Monthly Average Limits

    Chronic violations must be reported in the NNCR if the monthly 
average permit limits are exceeded any four months in a six-month 
period. These criteria apply to all Group I and Group II pollutants.

                       Group I Pollutants--TRC=1.4

Sec. 123.46  Individual control strategies.

    (a) Not later than February 4, 1989, each State shall submit to the 
Regional Administrator for review, approval, and implementation an 
individual control strategy for each point source identified by the 
State pursuant to section 304(l)(1)(C) of the Act which discharges to a 
water identified by the State pursuant to section 304(l)(1)(B) which 
will produce a reduction in the discharge of toxic pollutants from the 
point sources identified under section 304(l)(1)(C) through the 
establishment of effluent limitations under section 402 of the CWA and 
water quality standards under section 303(c)(2)(B) of the CWA, which 
reduction is sufficient, in combination with existing controls on point 
and nonpoint sources of pollution, to achieve the applicable water 
quality standard as soon as possible, but not later than three years 
after the date of establishment of such strategy.
    (b) The Administrator shall approve or disapprove the control 
strategies submitted by any State pursuant to paragraph (a) of this 
section, not later than June 4, 1989. If a State fails to submit control 
strategies in accordance with paragraph (a) of this section or the 
Administrator does not approve the control strategies submitted by such 
State in accordance with paragraph (a), then, not later than June 4, 
1990, the Administrator in cooperation with such State and after notice 
and opportunity for public comment, shall implement the requirements of 
CWA section 304(l)(1) in such State. In the implementation of such 
requirements, the Administrator shall, at a minimum, consider for 
listing under CWA section 304(l)(1) any navigable waters for which any 
person submits a petition to the Administrator for listing not later 
than October 1, 1989.
    (c) For the purposes of this section the term individual control 
strategy, as set forth in section 304(l) of the CWA, means a final NPDES 
permit with supporting documentation showing that effluent limits are 
consistent with an approved wasteload allocation, or other documentation 
which shows

[[Page 315]]

that applicable water quality standards will be met not later than three 
years after the individual control strategy is established. Where a 
State is unable to issue a final permit on or before February 4, 1989, 
an individual control strategy may be a draft permit with an attached 
schedule (provided the State meets the schedule for issuing the final 
permit) indicating that the permit will be issued on or before February 
4, 1990. If a point source is subject to section 304(l)(1)(C) of the CWA 
and is also subject to an on-site response action under sections 104 or 
106 of the Comprehensive Environmental Response, Compensation, and 
Liability Act of 1980 (CERCLA), (42 U.S.C. 9601 et seq.), an individual 
control strategy may be the decision document (which incorporates the 
applicable or relevant and appropriate requirements under the CWA) 
prepared under sections 104 or 106 of CERCLA to address the release or 
threatened release of hazardous substances to the environment.
    (d) A petition submitted pursuant to section 304(l)(3) of the CWA 
must be submitted to the appropriate Regional Administrator. Petitions 
must identify a waterbody in sufficient detail so that EPA is able to 
determine the location and boundaries of the waterbody. The petition 
must also identify the list or lists for which the waterbody qualifies, 
and the petition must explain why the waterbody satisfies the criteria 
for listing under CWA section 304(l) and 40 CFR 130.10(d)(6).
    (e) If the Regional Administrator disapproves one or more individual 
control strategies, or if a State fails to provide adequate public 
notice and an opportunity to comment on the ICSs, then, not later than 
June 4, 1989, the Regional Administrator shall give a notice of approval 
or disapproval of the individual control strategies submitted by each 
State pursuant to this section as follows:
    (1) The notice of approval or disapproval given under this paragraph 
shall include the following:
    (i) The name and address of the EPA office that reviews the State's 
submittals.
    (ii) A brief description of the section 304(l) process.
    (iii) A list of ICSs disapproved under this section and a finding 
that the ICSs will not meet all applicable review criteria under this 
section and section 304(l) of the CWA.
    (iv) If the Regional Administrator determines that a State did not 
provide adequate public notice and an opportunity to comment on the 
waters, point sources, or ICSs prepared pursuant to section 304(l), or 
if the Regional Administrator chooses to exercise his or her discretion, 
a list of the ICSs approved under this section, and a finding that the 
ICSs satisfy all applicable review criteria.
    (v) The location where interested persons may examine EPA's records 
of approval and disapproval.
    (vi) The name, address, and telephone number of the person at the 
Regional Office from whom interested persons may obtain more 
information.
    (vii) Notice that written petitions or comments are due within 120 
days.
    (2) The Regional Administrator shall provide the notice of approval 
or disapproval given under this paragraph to the appropriate State 
Director. The Regional Administrator shall publish a notice of 
availability, in a daily or weekly newspaper with State-wide circulation 
or in the Federal Register, for the notice of approval or disapproval. 
The Regional Administrator shall also provide written notice to each 
discharger identified under section 304(l)(1)(C), that EPA has listed 
the discharger under section 304(l)(1)(C).
    (3) As soon as practicable but not later than June 4, 1990, the 
Regional Offices shall issue a response to petitions or comments 
received under section 304(l). The response to comments shall be given 
in the same manner as the notice described in paragraph (e) of this 
section except for the following changes:
    (i) The lists of ICSs reflecting any changes made pursuant to 
comments or petitions received.
    (ii) A brief description of the subsequent steps in the section 
304(l) process.
    (f) EPA shall review, and approve or disapprove, the individual 
control strategies prepared under section 304(l)

[[Page 316]]

of the CWA, using the applicable criteria set forth in section 304(l) of 
the CWA, and in 40 CFR part 122, including Sec. 122.44(d). At any time 
after the Regional Administrator disapproves an ICS (or conditionally 
aproves a draft permit as an ICS), the Regional Office may submit a 
written notification to the State that the Regional Office intends to 
issue the ICS. Upon mailing the notification, and notwithstanding any 
other regulation, exclusive authority to issue the permit passes to EPA.

          Subpart D_Program Approval, Revision, and Withdrawal



Sec. 123.61  Approval process.

    (a) After determining that a State program submission is complete, 
EPA shall publish notice of the State's application in the Federal 
Register, and in enough of the largest newspapers in the State to 
attract statewide attention, and shall mail notice to persons known to 
be interested in such matters, including all persons on appropriate 
State and EPA mailing lists and all permit holders and applicants within 
the State. The notice shall:
    (1) Provide a comment period of not less than 45 days during which 
interested members of the public may express their views on the State 
program;
    (2) Provide for a public hearing within the State to be held no less 
than 30 days after notice is published in the Federal Register;
    (3) Indicate the cost of obtaining a copy of the State's submission;
    (4) Indicate where and when the State's submission may be reviewed 
by the public;
    (5) Indicate whom an interested member of the public should contact 
with any questions; and
    (6) Briefly outline the fundamental aspects of the State's proposed 
program, and the process for EPA review and decision.
    (b) Within 90 days of the receipt of a complete program submission 
under Sec. 123.21 the Administrator shall approve or disapprove the 
program based on the requirements of this part and of CWA and taking 
into consideration all comments received. A responsiveness summary shall 
be prepared by the Regional Office which identifies the public 
participation activities conducted, describes the matters presented to 
the public, summarizes significant comments received and explains the 
Agency's response to these comments.
    (c) If the Administrator approves the State's program he or she 
shall notify the State and publish notice in the Federal Register. The 
Regional Administrator shall suspend the issuance of permits by EPA as 
of the date of program approval.
    (d) If the Administrator disapproves the State program he or she 
shall notify the State of the reasons for disapproval and of any 
revisions or modifications to the State program which are necessary to 
obtain approval.

[48 FR 14178, Apr. 1, 1983; 50 FR 6941, Feb. 19, 1985]



Sec. 123.62  Procedures for revision of State programs.

    (a) Either EPA or the approved State may initiate program revision. 
Program revision may be necessary when the controlling Federal or State 
statutory or regulatory authority is modified or supplemented. The State 
shall keep EPA fully informed of any proposed modifications to its basic 
statutory or regulatory authority, its forms, procedures, or priorities. 
Grounds for program revision include cases where a State's existing 
approved program includes authority to issue NPDES permits for 
activities on a Federal Indian reservation and an Indian Tribe has 
subsequently been approved for assumption of the NPDES program under 40 
CFR part 123 extending to those lands.
    (b) Revision of a State program shall be accomplished as follows:
    (1) The State shall submit a modified program description, Attorney 
General's statement, Memorandum of Agreement, or such other documents as 
EPA determines to be necessary under the circumstances.
    (2) Whenever EPA determines that the proposed program revision is 
substantial, EPA shall issue public notice and provide an opportunity to 
comment for a period of at least 30 days.

[[Page 317]]

The public notice shall be mailed to interested persons and shall be 
published in the Federal Register and in enough of the largest 
newspapers in the State to provide Statewide coverage. The public notice 
shall summarize the proposed revisions and provide for the opportunity 
to request a public hearing. Such a hearing will be held if there is 
significant public interest based on requests received.
    (3) The Administrator will approve or disapprove program revisions 
based on the requirements of this part (or, in the case of a sewage 
sludge management program, 40 CFR part 501) and of the CWA.
    (4) A program revision shall become effective upon the approval of 
the Administrator. Notice of approval of any substantial revision shall 
be published in the Federal Register. Notice of approval of non-
substantial program revisions may be given by a letter from the 
Administrator to the State Governor or his designee.
    (c) States with approved programs must notify EPA whenever they 
propose to transfer all or part of any program from the approved State 
agency to any other State agency, and must identify any new division of 
responsibilities among the agencies involved. The new agency is not 
authorized to administer the program until approved by the Administrator 
under paragraph (b) of this section. Organizational charts required 
under Sec. 123.22(b) (or, in the case of a sewage sludge management 
program, Sec. 501.12(b) of this chapter) must be revised and 
resubmitted.
    (d) Whenever the Administrator has reason to believe that 
circumstances have changed with respect to a State program, he may 
request, and the State shall provide, a supplemental Attorney General's 
statement, program description, or such other documents or information 
as are necessary.
    (e) State NPDES programs only. All new programs must comply with 
these regulations immediately upon approval. Any approved State section 
402 permit program which requires revision to conform to this part shall 
be so revised within one year of the date of promulgation of these 
regulations, unless a State must amend or enact a statute in order to 
make the required revision in which case such revision shall take place 
within 2 years, except that revision of State programs to implement the 
requirements of 40 CFR part 403 (pretreatment) shall be accomplished as 
provided in 40 CFR 403.10. In addition, approved States shall submit, 
within 6 months, copies of their permit forms for EPA review and 
approval. Approved States shall also assure that permit applicants, 
other than POTWs, submit, as part of their application, the information 
required under Sec. Sec. 124.4(d) and 122.21 (g) or (h), as 
appropriate.
    (f) Revision of a State program by a Great Lakes State or Tribe (as 
defined in 40 CFR 132.2) to conform to section 118 of the CWA and 40 CFR 
part 132 shall be accomplished pursuant to 40 CFR part 132.

    (i) Failure to act on violations of permits or other program 
requirements;
    (ii) Failure to seek adequate enforcement penalties or to collect 
administrative fines when imposed; or
    (iii) Failure to inspect and monitor activities subject to 
regulation.
    (4) Where the State program fails to comply with the terms of the 
Memorandum of Agreement required under Sec. 123.24 (or, in the case of 
a sewage sludge management program, Sec. 501.14 of this chapter).
    (5) Where the State fails to develop an adequate regulatory program 
for developing water quality-based effluent limits in NPDES permits.
    (6) Where a Great Lakes State or Tribe (as defined in 40 CFR 132.2) 
fails to adequately incorporate the NPDES permitting implementation 
procedures promulgated by the State, Tribe, or EPA pursuant to 40 CFR 
part 132 into individual permits.
    (b) [Reserved]

[48 FR 14178, Apr. 1, 1983; 50 FR 6941, Feb. 19, 1985, as amended at 54 
FR 23897, June 2, 1989; 60 FR 15386, Mar. 23, 1995; 63 FR 45123, Aug. 
24, 1998]



Sec. 123.64  Procedures for withdrawal of State programs.

    (a) A State with a program approved under this part (or, in the case 
of a sewage sludge management program, 40 CFR part 501) may voluntarily 
transfer program responsibilities required by Federal law to EPA by 
taking the following actions, or in such other manner as may be agreed 
upon with the Administrator.
    (1) The State shall give the Administrator 180 days notice of the 
proposed transfer and shall submit a plan for the orderly transfer of 
all relevant program information not in the possession of EPA (such as 
permits, permit files, compliance files, reports, permit applications) 
which are necessary for EPA to administer the program.
    (2) Within 60 days of receiving the notice and transfer plan, the 
Administrator shall evaluate the State's transfer plan and shall 
identify any additional information needed by the Federal government for 
program administration and/or identify any other deficiencies in the 
plan.
    (3) At least 30 days before the transfer is to occur the 
Administrator shall publish notice of the transfer in the Federal 
Register and in enough of the largest newspapers in the State to provide 
Statewide coverage, and shall mail notice to all permit holders, permit 
applicants, other regulated persons and other interested persons on 
appropriate EPA and State mailing lists.
    (b) The following procedures apply when the Administrator orders the 
commencement of proceedings to determine whether to withdraw approval of 
a State program.
    (1) Order. The Administrator may order the commencement of 
withdrawal proceedings on his or her own initiative or in response to a 
petition from an interested person alleging failure of the State to 
comply with the requirements of this part as set forth in Sec. 123.63 
(or, in the case of a sewage sludge management program, Sec. 501.33 of 
this chapter). The Administrator will respond in writing to any petition 
to commence withdrawal proceedings. He may conduct an informal 
investigation of the allegations in the petition to determine whether 
cause exists to commence proceedings under this paragraph. The 
Administrator's order commencing proceedings under this paragraph will 
fix a time and place for the commencement of the hearing and will 
specify the allegations against the State which are to be considered at 
the hearing. Within 30 days the State must admit or deny these 
allegations in a written answer. The party seeking withdrawal of the 
State's program will have the burden of coming forward with the evidence 
in a hearing under this paragraph.
    (2) Definitions. For purposes of this paragraph the definitions of 
``Act,'' ``Administrative Law Judge,'' ``Hearing Clerk,'' and 
``Presiding Officer'' in 40 CFR 22.03 apply in addition to the 
following:
    (i) Party means the petitioner, the State, the Agency, and any other 
person whose request to participate as a party is granted.

[[Page 319]]

    (ii) Person means the Agency, the State and any individual or 
organization having an interest in the subject matter of the proceeding.
    (iii) Petitioner means any person whose petition for commencement of 
withdrawal proceedings has been granted by the Administrator.
    (3) Procedures. (i) The following provisions of 40 CFR part 22 
(Consolidated Rules of Practice) are applicable to proceedings under 
this paragraph:
    (A) Sec. 22.02--(use of number/gender);
    (B) Sec. 22.04(c)--(authorities of Presiding Officer);
    (C) Sec. 22.06--(filing/service of rulings and orders);
    (D) Sec. 22.09--(examination of filed documents);
    (E) Sec. 22.19(a), (b) and (c)--(prehearing conference);
    (F) Sec. 22.22--(evidence);
    (G) Sec. 22.23--(objections/offers of proof);
    (H) Sec. 22.25--(filing the transcript); and
    (I) Sec. 22.26--(findings/conclusions).
    (ii) The following provisions are also applicable:
    (A) Computation and extension of time--(1) Computation. In computing 
any period of time prescribed or allowed in these rules of practice, 
except as otherwise provided, the day of the event from which the 
designated period begins to run shall not be included. Saturdays, 
Sundays, and Federal legal holidays shall be included. When a stated 
time expires on a Saturday, Sunday, or legal holiday, the stated time 
period shall be extended to include the next business day.
    (2) Extensions of time. The Administrator, Regional Administrator, 
or Presiding Officer, as appropriate, may grant an extension of time for 
the filing of any pleading, document, or motion (i) upon timely motion 
of a party to the proceeding, for good cause shown, and after 
consideration of prejudice to other parties, or (ii) upon his own 
motion. Such a motion by a party may only be made after notice to all 
other parties, unless the movant can show good cause why serving notice 
is impracticable. The motion shall be filed in advance of the date on 
which the pleading, document or motion is due to be filed, unless the 
failure of a party to make timely motion for extension of time was the 
result of excusable neglect.
    (3) The time for commencement of the hearing shall not be extended 
beyond the date set in the Administrator's order without approval of the 
Administrator.
    (B) Ex parte discussion of proceedings. At no time after the 
issuance of the order commencing proceedings shall the Administrator, 
the Regional Administrator, the Regional Judicial Officer, the Presiding 
Officer, or any other person who is likely to advise these officials in 
the decision on the case, discuss ex parte the merits of the proceeding 
with any interested person outside the Agency, with any Agency staff 
member who performs a prosecutorial or investigative function in such 
proceeding or a factually related proceeding, or with any representative 
of such person. Any ex parte memorandum or other communication addressed 
to the Administrator, the Regional Administrator, the Regional Judicial 
Officer, or the Presiding Officer during the pendency of the proceeding 
and relating to the merits thereof, by or on behalf of any party, shall 
be regarded as argument made in the proceeding and shall be served upon 
all other parties. The other parties shall be given an opportunity to 
reply to such memorandum or communication.
    (C) Intervention--(1) Motion. A motion for leave to intervene in any 
proceeding conducted under these rules of practice must set forth the 
grounds for the proposed intervention, the position and interest of the 
movant and the likely impact that intervention will have on the 
expeditious progress of the proceeding. Any person already a party to 
the proceeding may file an answer to a motion to intervene, making 
specific reference to the factors set forth in the foregoing sentence 
and paragraph (b)(3)(ii)(C)(3) of this section, within ten (10) days 
after service of the motion for leave to intervene.
    (2) However, motions to intervene must be filed within 15 days from 
the date the notice of the Administrator's order is first published.
    (3) Disposition. Leave to intervene may be granted only if the 
movant demonstrates that (i) his presence in

[[Page 320]]

the proceeding would not unduly prolong or otherwise prejudice that 
adjudication of the rights of the original parties; (ii) the movant will 
be adversely affected by a final order; and (iii) the interests of the 
movant are not being adequately represented by the original parties. The 
intervenor shall become a full party to the proceeding upon the granting 
of leave to intervene.
    (4) Amicus curiae. Persons not parties to the proceeding who wish to 
file briefs may so move. The motion shall identify the interest of the 
applicant and shall state the reasons why the proposed amicus brief is 
desirable. If the motion is granted, the Presiding Officer or 
Administrator shall issue an order setting the time for filing such 
brief. An amicus curiae is eligible to participate in any briefing after 
his motion is granted, and shall be served with all briefs, reply 
briefs, motions, and orders relating to issues to be briefed.
    (D) Motions--(1) General. All motions, except those made orally on 
the record during a hearing, shall (i) be in writing; (ii) state the 
grounds therefor with particularity; (iii) set forth the relief or order 
sought; and (iv) be accompanied by any affidavit, certificate, other 
evidence, or legal memorandum relied upon. Such motions shall be served 
as provided by paragraph (b)(4) of this section.
    (2) Response to motions. A party's response to any written motion 
must be filed within ten (10) days after service of such motion, unless 
additional time is allowed for such response. The response shall be 
accompanied by any affidavit, certificate, other evidence, or legal 
memorandum relied upon. If no response is filed within the designated 
period, the parties may be deemed to have waived any objection to the 
granting of the motion. The Presiding Officer, Regional Administrator, 
or Administrator, as appropriate, may set a shorter time for response, 
or make such other orders concerning the disposition of motions as they 
deem appropriate.
    (3) Decision. The Administrator shall rule on all motions filed or 
made after service of the recommended decision upon the parties. The 
Presiding Officer shall rule on all other motions. Oral argument on 
motions will be permitted where the Presiding Officer, Regional 
Administrator, or the Administrator considers it necessary or desirable.
    (4) Record of proceedings. (i) The hearing shall be either 
stenographically reported verbatim or tape recorded, and thereupon 
transcribed by an official reporter designated by the Presiding Officer;
    (ii) All orders issued by the Presiding Officer, transcripts of 
testimony, written statements of position, stipulations, exhibits, 
motions, briefs, and other written material of any kind submitted in the 
hearing shall be a part of the record and shall be available for 
inspection or copying in the Office of the Hearing Clerk, upon payment 
of costs. Inquiries may be made at the Office of the Administrative Law 
Judges, Hearing Clerk, 1200 Pennsylvania Ave., NW., Washington, DC 
20460;
    (iii) Upon notice to all parties the Presiding Officer may authorize 
corrections to the transcript which involves matters of substance;
    (iv) An original and two (2) copies of all written submissions to 
the hearing shall be filed with the Hearing Clerk;

                 Subpart A_General Program Requirements



Sec. 124.1  Purpose and scope.

    (a) This part contains EPA procedures for issuing, modifying, 
revoking and reissuing, or terminating all RCRA, UIC, PSD and NPDES 
``permits'' (including ``sludge-only'' permits issued pursuant to Sec. 
122.1(b)(2) of this chapter. The latter kinds of permits are governed by 
part 270. RCRA interim status and UIC authorization by

[[Page 323]]

rule are not ``permits'' and are covered by specific provisions in parts 
144, subpart C, and 270. This part also does not apply to permits 
issued, modified, revoked and reissued or terminated by the Corps of 
Engineers. Those procedures are specified in 33 CFR parts 320-327. The 
procedures of this part also apply to denial of a permit for the active 
life of a RCRA hazardous waste management facility or unit under Sec. 
270.29.
    (b) Part 124 is organized into five subparts. Subpart A contains 
general procedural requirements applicable to all permit programs 
covered by these provisions. Subparts B through D and Subpart G 
supplement these general provisions with requirements that apply to only 
one or more of the programs. Subpart A describes the steps EPA will 
follow in receiving permit applications, preparing draft permits, 
issuing public notice, inviting public comment and holding public 
hearings on draft permits. Subpart A also covers assembling an 
administrative record, responding to comments, issuing a final permit 
decision, and allowing for administrative appeal of the final permit 
decisions. Subpart B contains public participation requirements 
applicable to all RCRA hazardous waste management facilities. Subpart C 
contains definitions and specific procedural requirements for PSD 
permits. Subpart D contains specific procedural requirements for NPDES 
permits. Subpart G contains specific procedural requirements for RCRA 
standardized permits, which, in some instances, change how the General 
Program Requirements of subpart A apply in the context of the RCRA 
standardized permit.
    (c) Part 124 offers an opportunity for public hearings (see Sec. 
124.12).
    (d) This part is designed to allow permits for a given facility 
under two or more of the listed programs to be processed separately or 
together at the choice of the Regional Administrator. This allows EPA to 
combine the processing of permits only when appropriate, and not 
necessarily in all cases. The Regional Administrator may consolidate 
permit processing when the permit applications are submitted, when draft 
permits are prepared, or when final permit decisions are issued. This 
part also allows consolidated permits to be subject to a single public 
hearing under Sec. 124.12. Permit applicants may recommend whether or 
not their applications should be consolidated in any given case.
    (e) Certain procedural requirements set forth in part 124 must be 
adopted by States in order to gain EPA approval to operate RCRA, UIC, 
NPDES, and 404 permit programs. These requirements are listed in 
Sec. Sec. 123.25 (NPDES), 145.11 (UIC), 233,26 (404), and 271.14 (RCRA) 
and signaled by the following words at the end of the appropriate part 
124 section or paragraph heading: (applicable to State programs see 
Sec. Sec. 123.25 (NPDES), 145.11 (UIC), 233.26 (404), and 271.14 
(RCRA)). Part 124 does not apply to PSD permits issued by an approved 
State.
    (f) To coordinate decisionmaking when different permits will be 
issued by EPA and approved State programs, this part allows applications 
to be jointly processed, joint comment periods and hearings to be held, 
and final permits to be issued on a cooperative basis whenever EPA and a 
State agree to take such steps in general or in individual cases. These 
joint processing agreements may be provided in the Memorandum of 
Agreement developed under Sec. Sec. 123.24 (NPDES), 145.24 (UIC), 
233.24 (404), and 271.8 (RCRA).

[48 FR 14264, Apr. 1, 1983, as amended at 54 FR 9607, Mar. 7, 1989; 54 
FR 18785, May 2, 1989; 65 FR 30910, May 15, 2000; 70 FR 53448, Sept. 8, 
2005]



Sec. 124.2  Definitions.

    (a) In addition to the definitions given in Sec. Sec. 122.2 and 
123.2 (NPDES), 501.2 (sludge management), 144.3 and 145.2 (UIC), 233.3 
(404), and 270.2 and 271.2 (RCRA), the definitions below apply to this 
part, except for PSD permits which are governed by the definitions in 
Sec. 124.41. Terms not defined in this section have the meaning given 
by the appropriate Act.
    Administrator means the Administrator of the U.S. Environmental 
Protection Agency, or an authorized representative.
    Application means the EPA standard national forms for applying for a 
permit, including any additions, revisions or modifications to the 
forms; or forms

[[Page 324]]

approved by EPA for use in ``approved States,'' including any approved 
modifications or revisions. For RCRA, application also includes the 
information required by the Director under Sec. Sec. 270.14 through 
270.29 [contents of Part B of the RCRA application].
    Appropriate Act and regulations means the Clean Water Act (CWA); the 
Solid Waste Disposal Act, as amended by the Resource Conservation 
Recovery Act (RCRA); or Safe Drinking Water Act (SDWA), whichever is 
applicable; and applicable regulations promulgated under those statutes. 
In the case of an ``approved State program'' appropriate Act and 
regulations includes program requirements.
    CWA means the Clean Water Act (formerly referred to as the Federal 
Water Pollution Control Act of Federal Pollution Control Act Amendments 
of 1972) Public Law 92-500, as amended by Public Law 95-217 and Public 
Law 95-576; 33 U.S.C. 1251 et seq.
    Director means the Regional Administrator, the State director or the 
Tribal director as the context requires, or an authorized 
representative. When there is no approved State or Tribal program, and 
there is an EPA administered program, Director means the Regional 
Administrator. When there is an approved State or Tribal program, 
``Director'' normally means the State or Tribal director. In some 
circumstances, however, EPA retains the authority to take certain 
actions even when there is an approved State or Tribal program. (For 
example, when EPA has issued an NPDES permit prior to the approval of a 
State program, EPA may retain jurisdiction over that permit after 
program approval; see Sec. 123.1) In such cases, the term ``Director'' 
means the Regional Administrator and not the State or Tribal director.
    Draft permit means a document prepared under Sec. 124.6 indicating 
the Director's tentative decision to issue or deny, modify, revoke and 
reissue, terminate, or reissue a ``permit.'' A notice of intent to 
terminate a permit and a notice of intent to deny a permit as discussed 
in Sec. 124.5, are types of ``draft permits.'' A denial of a request 
for modification, revocation and reissuance or termination, as discussed 
in Sec. 124.5, is not a ``draft permit.'' A ``proposal permit'' is not 
a ``draft permit.''
    Environmental Appeals Board shall mean the Board within the Agency 
described in Sec. 1.25(e) of this title. The Administrator delegates 
authority to the Environmental Appeals Board to issue final decisions in 
RCRA, PSD, UIC, or NPDES permit appeals filed under this subpart, 
including informal appeals of denials of requests for modification, 
revocation and reissuance, or termination of permits under Section 
124.5(b). An appeal directed to the Administrator, rather than to the 
Environmental Appeals Board, will not be considered. This delegation 
does not preclude the Environmental Appeals Board from referring an 
appeal or a motion under this subpart to the Administrator when the 
Environmental Appeals Board, in its discretion, deems it appropriate to 
do so. When an appeal or motion is referred to the Administrator by the 
Environmental Appeals Board, all parties shall be so notified and the 
rules in this subpart referring to the Environmental Appeals Board shall 
be interpreted as referring to the Administrator.
    EPA (``EPA'') means the United States ``Environmental Protection 
Agency.''
    Facility or activity means any ``HWM facility,'' UIC ``injection 
well,'' NPDES ``point source'' or ``treatment works treating domestic 
sewage'' or State 404 dredge or fill activity, or any other facility or 
activity (including land or appurtenances thereto) that is subject to 
regulation under the RCRA, UIC, NPDES, or 404 programs.
    Federal Indian reservation (in the case of NPDES) means all land 
within the limits of any Indian reservation under the jurisdiction of 
the United States Government, notwithstanding the issuance of any 
patent, and including rights-of-way running through the reservation.
    General permit (NPDES and 404) means an NPDES or 404 ``permit'' 
authorizing a category of discharges or activities under the CWA within 
a geographical area. For NPDES, a general permit means a permit issued 
under Sec. 122.28. For 404, a general permit means a permit issued 
under Sec. 233.37.

[[Page 325]]

    Indian Tribe means (in the case of UIC) any Indian Tribe having a 
federally recognized governing body carrying out substantial 
governmental duties and powers over a defined area. For the NPDES 
program, the term ``Indian Tribe'' means any Indian Tribe, band, group, 
or community recognized by the Secretary of the Interior and exercising 
governmental authority over a Federal Indian reservation.
    Interstate agency means an agency of two or more States established 
by or under an agreement or compact approved by the Congress, or any 
other agency of two or more States having substantial powers or duties 
pertaining to the control of pollution as determined and approved by the 
Administrator under the ``appropriate Act and regulations.''
    Major facility means any RCRA, UIC, NPDES, or 404 ``facility or 
activity'' classified as such by the Regional Administrator, or, in the 
case of ``approved State programs,'' the Regional Administrator in 
conjunction with the State Director.
    Owner or operator means owner or operator of any ``facility or 
activity'' subject to regulation under the RCRA, UIC, NPDES, or 404 
programs.
    Permit means an authorization, license or equivalent control 
document issued by EPA or an ``approved State'' to implement the 
requirements of this part and parts 122, 123, 144, 145, 233, 270, and 
271 of this chapter. ``Permit'' includes RCRA ``permit by rule'' (Sec. 
270.60), RCRA standardized permit (Sec. 270.67), UIC area permit (Sec. 
144.33), NPDES or 404 ``general permit'' (Sec. Sec. 270.61, 144.34, and 
233.38). Permit does not include RCRA interim status (Sec. 270.70), UIC 
authorization by rule (Sec. 144.21), or any permit which has not yet 
been the subject of final agency action, such as a ``draft permit'' or a 
``proposed permit.''
    Person means an individual, association, partnership, corporation, 
municipality, State, Federal, or Tribal agency, or an agency or employee 
thereof.
    RCRA means the Solid Waste Disposal Act as amended by the Resource 
Conservation and Recovery Act of 1976 (Pub. L. 94-580, as amended by 
Pub. L. 95-609, 42 U.S.C. 6901 et seq).
    Regional Administrator means the Regional Administrator of the 
appropriate Regional Office of the Environmental Protection Agency or 
the authorized representative of the Regional Administrator.
    Schedule of compliance means a schedule of remedial measures 
included in a ``permit,'' including an enforceable sequence of interim 
requirements (for example, actions, operations, or milestone events) 
leading to compliance with the ``appropriate Act and regulations.''
    SDWA means the Safe Drinking Water Act (Pub. L. 95-523, as amended 
by Pub. L. 95-1900; 42 U.S.C. 300f et seq).
    Section 404 program or State 404 program or 404 means an ``approved 
State program'' to regulate the ``discharge of dredged material'' and 
the ``discharge of fill material'' under section 404 of the Clean Water 
Act in ``State regulated waters.''
    Site means the land or water area where any ``facility or activity'' 
is physically located or conducted, including adjacent land used in 
connection with the facility or activity.
    Standardized permit means a RCRA permit authorizing management of 
hazardous waste issued under subpart G of this part and part 270, 
subpart J. The standardized permit may have two parts: A uniform portion 
issued in all cases and a supplemental portion issued at the Director's 
discretion.
    State means one of the States of the United States, the District of 
Columbia, the Commonwealth of Puerto Rico, the Virgin Islands, Guam, 
American Samoa, the Trust Territory of the Pacific Islands (except in 
the case of RCRA), the Commonwealth of the Northern Mariana Islands, or 
an Indian Tribe that meets the statutory criteria which authorize EPA to 
treat the Tribe in a manner similar to that in which it treats a State 
(except in the case of RCRA).
    State Director means the chief administrative officer of any State, 
interstate, or Tribal agency operating an approved program, or the 
delegated representative of the State director. If the responsibility is 
divided among two or more States, interstate, or Tribal agencies, 
``State Director'' means the chief administrative officer of the

[[Page 326]]

State, interstate, or Tribal agency authorized to perform the particular 
procedure or function to which reference is made.
    State Director means the chief administrative officer of any State 
or interstate agency operating an ``approved program,'' or the delegated 
representative of the state Director. If responsibility is divided among 
two or more State or interstate agencies, ``State Director'' means the 
chief administrative officer of the State or interstate agency 
authorized to perform the particular procedure or function to which 
reference is made.
    UIC means the Underground Injection Control program under Part C of 
the Safe Drinking Water Act, including an ``approved program.''
    (b) For the purposes of part 124, the term Director means the State 
Director or Regional Administrator and is used when the accompanying 
provision is required of EPA-administered programs and of State programs 
under Sec. Sec. 123.25 (NPDES), 145.11 (UIC), 233.26 (404), and 271.14 
(RCRA). The term Regional Administrator is used when the accompanying 
provision applies exclusively to EPA-issued permits and is not 
applicable to State programs under these sections. While States are not 
required to implement these latter provisions, they are not precluded 
from doing so, notwithstanding use of the term ``Regional 
Administrator.''

Sec. 124.3  Application for a permit.

    (a) Applicable to State programs, see Sec. Sec. 123.25 (NPDES), 
145.11 (UIC), 233.26 (404), and 271.14 (RCRA). (1) Any person who 
requires a permit under the RCRA, UIC, NPDES, or PSD programs shall 
complete, sign, and submit to the Director an application for each 
permit required under Sec. Sec. 270.1 (RCRA), 144.1 (UIC), 40 CFR 52.21 
(PSD), and 122.1 (NPDES). Applications are not required for RCRA permits 
by rule (Sec. 270.60), underground injections authorized by rules 
(Sec. Sec. 144.21 through 144.26), NPDES general permits (Sec. 122.28) 
and 404 general permits (Sec. 233.37).
    (2) The Director shall not begin the processing of a permit until 
the applicant has fully complied with the application requirements for 
that permit. See Sec. Sec. 270.10, 270.13 (RCRA), 144.31 (UIC), 40 CFR 
52.21 (PSD), and 122.21 (NPDES).
    (3) Permit applications (except for PSD permits) must comply with 
the signature and certification requirements of Sec. Sec. 122.22 
(NPDES), 144.32 (UIC), 233.6 (404), and 270.11 (RCRA).
    (b) [Reserved]
    (c) The Regional Administrator shall review for completeness every 
application for an EPA-issued permit. Each application for an EPA-issued 
permit submitted by a new HWM facility, a new UIC injection well, a 
major PSD stationary source or major PSD modification, or an NPDES new 
source or NPDES new discharger should be reviewed for completeness by 
the Regional Administrator within 30 days of its receipt. Each 
application for an EPA-issued permit submitted by an existing HWM 
facility (both Parts A and B of the application), existing injection 
well or existing NPDES source or sludge-only facility should be reviewed 
for completeness within 60 days of receipt. Upon completing the review, 
the Regional Administrator shall notify the applicant in writing whether 
the application is complete. If the application is incomplete, the 
Regional Administrator shall list the information necessary to make the 
application complete. When the application is for an existing HWM 
facility, an existing UIC injection well or an existing NPDES source or 
``sludge-only facility'' the Regional Administrator shall specify in the 
notice of deficiency a date for submitting the necessary information. 
The Regional Administrator shall notify the applicant that the 
application is complete upon receiving this information. After the 
application is completed, the Regional Administrator may request 
additional information from an applicant but only when necessary to 
clarify, modify, or supplement previously submitted material. Requests 
for such additional information will not render an application 
incomplete.

[[Page 327]]

    (d) If an applicant fails or refuses to correct deficiencies in the 
application, the permit may be denied and appropriate enforcement 
actions may be taken under the applicable statutory provision including 
RCRA section 3008, SDWA sections 1423 and 1424, CAA section 167, and CWA 
sections 308, 309, 402(h), and 402(k).
    (e) If the Regional Administrator decides that a site visit is 
necessary for any reason in conjunction with the processing of an 
application, he or she shall notify the applicant and a date shall be 
scheduled.
    (f) The effective date of an application is the date on which the 
Regional Administrator notifies the applicant that the application is 
complete as provided in paragraph (c) of this section.
    (g) For each application from a major new HWM facility, major new 
UIC injection well, major NPDES new source, major NPDES new discharger, 
or a permit to be issued under provisions of Sec. 122.28(c), the 
Regional Administrator shall, no later than the effective date of the 
application, prepare and mail to the applicant a project decision 
schedule. (This paragraph does not apply to PSD permits.) The schedule 
shall specify target dates by which the Regional Administrator intends 
to:
    (1) Prepare a draft permit;
    (2) Give public notice;
    (3) Complete the public comment period, including any public 
hearing; and
    (4) Issue a final permit.

Sec. 124.4  Consolidation of permit processing.

    (a)(1) Whenever a facility or activity requires a permit under more 
than one statute covered by these regulations, processing of two or more 
applications for those permits may be consolidated. The first step in 
consolidation is to prepare each draft permit at the same time.
    (2) Whenever draft permits are prepared at the same time, the 
statements of basis (required under Sec. 124.7 for EPA-issued permits 
only) or fact sheets (Sec. 124.8), administrative records (required 
under Sec. 124.9 for EPA-issued permits only), public comment periods 
(Sec. 124.10), and any public hearings (Sec. 124.12) on those permits 
should also be consolidated. The final permits may be issued together. 
They need not be issued together if in the judgment of the Regional 
Administrator or State Director(s), joint processing would result in 
unreasonable delay in the issuance of one or more permits.
    (b) Whenever an existing facility or activity requires additional 
permits under one or more of the statutes covered by these regulations, 
the permitting authority may coordinate the expiration date(s) of the 
new permit(s) with the expiration date(s) of the existing permit(s) so 
that all permits expire simultaneously. Processing of the subsequent 
applications for renewal permits may then be consolidated.
    (c) Processing of permit applications under paragraph (a) or (b) of 
this section may be consolidated as follows:
    (1) The Director may consolidate permit processing at his or her 
discretion whenever a facility or activity requires all permits either 
from EPA or from an approved State.
    (2) The Regional Administrator and the State Director(s) may agree 
to consolidate draft permits whenever a facility or activity requires 
permits from both EPA and an approved State.
    (3) Permit applicants may recommend whether or not the processing of 
their applications should be consolidated.
    (d) [Reserved]
    (e) Except with the written consent of the permit applicant, the 
Regional Administrator shall not consolidate processing a PSD permit 
with any other permit under paragraph (a) or (b) of this section when to 
do so would delay issuance of the PSD permit more than one year from the 
effective date of the application under Sec. 124.3(f).

Sec. 124.5  Modification, revocation and reissuance, or termination
of permits.

    (a) (Applicable to State programs, see Sec. Sec. 123.25 (NPDES), 
145.11 (UIC), 233.26 (404), and 271.14 (RCRA).) Permits (other than PSD 
permits) may be modified, revoked and reissued, or terminated either at 
the request of any interested person (including the permittee) or upon 
the Director's initiative. However, permits may only be modified, 
revoked and reissued, or terminated for the reasons specified in Sec. 
122.62 or Sec. 122.64 (NPDES), 144.39 or 144.40 (UIC), 233.14 or 233.15 
(404), and 270.41 or 270.43 (RCRA). All requests shall be in writing and 
shall contain facts or reasons supporting the request.
    (b) If the Director decides the request is not justified, he or she 
shall send the requester a brief written response giving a reason for 
the decision. Denials of requests for modification, revocation and 
reissuance, or termination are not subject to public notice, comment, or 
hearings. Denials by the Regional Administrator may be informally 
appealed to the Environmental Appeals Board by a letter briefly setting 
forth the relevant facts. The Environmental Appeals Board may direct the 
Regional Administrator to begin modification, revocation and reissuance, 
or termination proceedings under paragraph (c) of this section. The 
appeal shall be considered denied if the Environmental Appeals Board 
takes no action on the letter within 60 days after receiving it. This 
informal appeal is, under 5 U.S.C. 704, a prerequisite to seeking 
judicial review of EPA action in denying a request for modification, 
revocation and reissuance, or termination.
    (c) (Applicable to State programs, see 40 CFR 123.25 (NPDES), 145.11 
(UIC), 233.26 (404), and 271.14 (RCRA)). (1) If the Director tentatively 
decides to modify or revoke and reissue a permit under 40 CFR 122.62 
(NPDES), 144.39 (UIC), 233.14 (404), or 270.41 (other than Sec. 
270.41(b)(3)) or Sec. 270.42(c) (RCRA), he or she shall prepare a draft 
permit under Sec. 124.6 incorporating the proposed changes. The 
Director may request additional information and, in the case of a 
modified permit, may require the submission of an updated application. 
In the case of revoked and reissued permits, other than under 40 CFR 
270.41(b)(3), the Director shall require the submission of a new 
application. In the case of revoked and reissued permits under 40 CFR 
270.41(b)(3), the Director and the permittee shall comply with the 
appropriate requirements in 40 CFR part 124, subpart G for RCRA 
standardized permits.
    (2) In a permit modification under this section, only those 
conditions to be modified shall be reopened when a new draft permit is 
prepared. All other aspects of the existing permit shall remain in 
effect for the duration of the unmodified permit. When a permit is 
revoked and reissued under this section, the entire permit is reopened 
just as if the permit had expired and was being reissued. During any 
revocation and reissuance proceeding the permittee shall comply with all 
conditions of the existing permit until a new final permit is reissued.
    (3) ``Minor modifications'' as defined in Sec. Sec. 122.63 (NPDES), 
144.41 (UIC), and 233.16 (404), and ``Classes 1 and 2 modifications'' as 
defined in Sec. 270.42 (a) and (b) (RCRA) are not subject to the 
requirements of this section.
    (d) (Applicable to State programs, see Sec. Sec. 123.25 (NPDES) of 
this chapter, 145.11 (UIC) of this chapter, and 271.14 (RCRA) of this 
chapter.) (1) If the Director tentatively decides to terminate: A permit 
under Sec. 144.40 (UIC) of this chapter, a permit under Sec. Sec. 
122.64(a) (NPDES) of this chapter or 270.43 (RCRA) of this chapter (for 
EPA-issued NPDES permits, only at the request of the permittee), or a 
permit under Sec. 122.64(b) (NPDES) of this chapter where the permittee 
objects, he or she shall issue a notice of intent to terminate. A notice 
of intent to terminate is a type of draft permit which follows the same 
procedures as any draft permit prepared under Sec. 124.6 of this 
chapter.
    (2) For EPA-issued NPDES or RCRA permits, if the Director 
tentatively decides to terminate a permit under Sec. 122.64(a) (NPDES) 
of this chapter, other than at the request of the permittee, or decides 
to conduct a hearing under section 3008 of RCRA in connection with the 
termination of a RCRA permit, he or she shall prepare a complaint under 
40 CFR 22.13 and 22.44 of this chapter. Such termination of

[[Page 329]]

NPDES and RCRA permits shall be subject to the procedures of part 22 of 
this chapter.
    (3) In the case of EPA-issued permits, a notice of intent to 
terminate or a complaint shall not be issued if the Regional 
Administrator and the permittee agree to termination in the course of 
transferring permit responsibility to an approved State under Sec. Sec. 
123.24(b)(1) (NPDES) of this chapter, 145.25(b)(1) (UIC) of this 
chapter, 271.8(b)(6) (RCRA) of this chapter, or 501.14(b)(1) (sludge) of 
this chapter. In addition, termination of an NPDES permit for cause 
pursuant to Sec. 122.64 of this chapter may be accomplished by 
providing written notice to the permittee, unless the permittee objects.
    (e) When EPA is the permitting authority, all draft permits 
(including notices of intent to terminate) prepared under this section 
shall be based on the administrative record as defined in Sec. 124.9.
    (f) (Applicable to State programs, see Sec. 233.26 (404).) Any 
request by the permittee for modification to an existing 404 permit 
(other than a request for a minor modification as defined in Sec. 
233.16 (404)) shall be treated as a permit application and shall be 
processed in accordance with all requirements of Sec. 124.3.
    (g)(1) (Reserved for PSD Modification Provisions).
    (2) PSD permits may be terminated only by rescission under Sec. 
52.21(w) or by automatic expiration under Sec. 52.21(r). Applications 
for rescission shall be precessed under Sec. 52.21(w) and are not 
subject to this part.

Sec. 124.6  Draft permits.

    (a) (Applicable to State programs, see Sec. Sec. 123.25 (NPDES), 
145.11 (UIC), 233.26 (404), and 271.14 (RCRA).) Once an application is 
complete, the Director shall tentatively decide whether to prepare a 
draft permit (except in the case of State section 404 permits for which 
no draft permit is required under Sec. 233.39) or to deny the 
application.
    (b) If the Director tentatively decides to deny the permit 
application, he or she shall issue a notice of intent to deny. A notice 
of intent to deny the permit application is a type of draft permit which 
follows the same procedures as any draft permit prepared under this 
section. See Sec. 124.6(e). If the Director's final decision (Sec. 
124.15) is that the tentative decision to deny the permit application 
was incorrect, he or she shall withdraw the notice of intent to deny and 
proceed to prepare a draft permit under paragraph (d) of this section.
    (c) (Applicable to State programs, see Sec. Sec. 123.25 (NPDES) and 
233.26 (404).) If the Director tentatively decides to issue an NPDES or 
404 general permit, he or she shall prepare a draft general permit under 
paragraph (d) of this section.
    (d) (Applicable to State programs, see Sec. Sec. 123.25 (NPDES), 
145.11 (UIC), 233.26 (404), and 271.14 (RCRA).) If the Director decides 
to prepare a draft permit, he or she shall prepare a draft permit that 
contains the following information:
    (1) All conditions under Sec. Sec. 122.41 and 122.43 (NPDES), 
144.51 and 144.42 (UIC, 233.7 and 233.8 (404, or 270.30 and 270.32 
(RCRA) (except for PSD permits)));
    (2) All compliance schedules under Sec. Sec. 122.47 (NPDES), 144.53 
(UIC), 233.10 (404), or 270.33 (RCRA) (except for PSD permits);
    (3) All monitoring requirements under Sec. Sec. 122.48 (NPDES), 
144.54 (UIC), 233.11 (404), or 270.31 (RCRA) (except for PSD permits); 
and
    (4) For:
    (i) RCRA permits, standards for treatment, storage, and/or disposal 
and other permit conditions under Sec. 270.30;
    (ii) UIC permits, permit conditions under Sec. 144.52;
    (iii) PSD permits, permit conditions under 40 CFR Sec. 52.21;
    (iv) 404 permits, permit conditions under Sec. Sec. 233.7 and 
233.8;

conditions certified by a State agency under Sec. 124.55, and all 
variances that are to be included under Sec. 124.63.

(404), and 271.14 (RCRA).) All draft permits prepared by EPA under this 
section shall be accompanied by a statement of basis (Sec. 124.7) or 
fact sheet (Sec. 124.8), and shall be based on the administrative 
record (Sec. 124.9), publicly noticed (Sec. 124.10) and made available 
for public comment (Sec. 124.11). The Regional Administrator shall give 
notice of opportunity for a public hearing (Sec. 124.12), issue a final 
decision (Sec. 124.15) and respond to comments (Sec. 124.17). For 
RCRA, UIC or PSD permits, an appeal may be taken under Sec. 124.19 and,

Sec. 124.7  Statement of basis.

    EPA shall prepare a statement of basis for every draft permit for 
which a fact sheet under Sec. 124.8 is not prepared. The statement of 
basis shall briefly describe the derivation of the conditions of the 
draft permit and the reasons for them or, in the case of notices of 
intent to deny or terminate, reasons supporting the tentative decision. 
The statement of basis shall be sent to the applicant and, on request,

Sec. 124.9  Administrative record for draft permits when EPA is the
permitting authority.

    (a) The provisions of a draft permit prepared by EPA under Sec. 
124.6 shall be based on the administrative record defined in this

issued.
    (2) Public notice of a public hearing shall be given at least 30 
days before the hearing. (Public notice of the hearing may be given at 
the same time as public notice of the draft permit and the two notices

Sec. 124.11  Public comments and requests for public hearings.

    (Applicable to State programs, see Sec. Sec. 123.25 (NPDES), 145.11 
(UIC), 233.26 (404), and 271.14 (RCRA).) During the public comment 
period provided under Sec. 124.10, any interested person may submit 
written comments on the draft permit or the permit application for 404 
permits when no draft permit is required (see Sec. 233.39) and may 
request a public hearing, if no hearing has already been scheduled. A 
request for a public hearing shall be in writing and shall state the 
nature of the issues proposed to be raised in the hearing. All comments 
shall be considered in making the final decision and shall be answered 
as provided in Sec. 124.17.



Sec. 124.12  Public hearings.

    (a) (Applicable to State programs, see Sec. Sec. 123.25 (NPDES), 
145.11 (UIC), 233.26 (404), and 271.14 (RCRA).) (1) The Director shall 
hold a public hearing whenever he or she finds, on the basis of 
requests, a significant degree of public interest in a draft permit(s);
    (2) The Director may also hold a public hearing at his or her 
discretion, whenever, for instance, such a hearing might clarify one or 
more issues involved in the permit decision;
    (3) For RCRA permits only, (i) the Director shall hold a public 
hearing whenever he or she receives written notice of opposition to a 
draft permit and a request for a hearing within 45 days of public notice 
under Sec. 124.10(b)(1); (ii) whenever possible the Director shall 
schedule a hearing under this section at a location convenient to the 
nearest population center to the proposed facility;
    (4) Public notice of the hearing shall be given as specified in 
Sec. 124.10.
    (b) Whenever a public hearing will be held and EPA is the permitting 
authority, the Regional Administrator shall designate a Presiding 
Officer for the hearing who shall be responsible for its scheduling and 
orderly conduct.
    (c) Any person may submit oral or written statements and data 
concerning the draft permit. Reasonable limits may be set upon the time 
allowed for oral statements, and the submission of statements in writing 
may be required. The public comment period under Sec. 124.10 shall 
automatically be extended to the close of any public hearing under this 
section. The hearing officer may also extend the comment period by so 
stating at the hearing.

[[Page 335]]

    (d) A tape recording or written transcript of the hearing shall be 
made available to the public.

2000]



Sec. 124.13  Obligation to raise issues and provide information during
the public comment period.

    All persons, including applicants, who believe any condition of a 
draft permit is inappropriate or that the Director's tentative decision 
to deny an application, terminate a permit, or prepare a draft permit is 
inappropriate, must raise all reasonably ascertainable issues and submit 
all reasonably available arguments supporting their position by the 
close of the public comment period (including any public hearing) under 
Sec. 124.10. Any supporting materials which are submitted shall be 
included in full and may not be incorporated by reference, unless they 
are already part of the administrative record in the same proceeding, or 
consist of State or Federal statutes and regulations, EPA documents of 
general applicability, or other generally available reference materials. 
Commenters shall make supporting materials not already included in the 
administrative record available to EPA as directed by the Regional 
Administrator. (A comment period longer than 30 days may be necessary to 
give commenters a reasonable opportunity to comply with the requirements 
of this section. Additional time shall be granted under Sec. 124.10 to 
the extent that a commenter who requests additional time demonstrates 
the need for such time.)

[49 FR 38051, Sept. 26, 1984]



Sec. 124.14  Reopening of the public comment period.

    (a)(1) The Regional Administrator may order the public comment 
period reopened if the procedures of this paragraph could expedite the 
decisionmaking process. When the public comment period is reopened under 
this paragraph, all persons, including applicants, who believe any 
condition of a draft permit is inappropriate or that the Regional 
Administrator's tentative decision to deny an application, terminate a 
permit, or prepare a draft permit is inappropriate, must submit all 
reasonably available factual grounds supporting their position, 
including all supporting material, by a date, not less than sixty days 
after public notice under paragraph (a)(2) of this section, set by the 
Regional Administrator. Thereafter, any person may file a written 
response to the material filed by any other person, by a date, not less 
than twenty days after the date set for filing of the material, set by 
the Regional Administrator.
    (2) Public notice of any comment period under this paragraph shall 
identify the issues to which the requirements of Sec. 124.14(a) shall 
apply.
    (3) On his own motion or on the request of any person, the Regional 
Administrator may direct that the requirements of paragraph (a)(1) of 
this section shall apply during the initial comment period where it 
reasonably appears that issuance of the permit will be contested and 
that applying the requirements of paragraph (a)(1) of this section will 
substantially expedite the decisionmaking process. The notice of the 
draft permit shall state whenever this has been done.
    (4) A comment period of longer than 60 days will often be necessary 
in complicated proceedings to give commenters a reasonable opportunity 
to comply with the requirements of this section. Commenters may request 
longer comment periods and they shall be granted under Sec. 124.10 to 
the extent they appear necessary.
    (b) If any data information or arguments submitted during the public 
comment period, including information or arguments required under Sec. 
124.13, appear to raise substantial new questions concerning a permit, 
the Regional Administrator may take one or more of the following 
actions:
    (1) Prepare a new draft permit, appropriately modified, under Sec. 
124.6;
    (2) Prepare a revised statement of basis under Sec. 124.7, a fact 
sheet or revised fact sheet under Sec. 124.8 and reopen the comment 
period under Sec. 124.14; or
    (3) Reopen or extend the comment period under Sec. 124.10 to give 
interested persons an opportunity to comment on the information or 
arguments submitted.

[[Page 336]]

    (c) Comments filed during the reopened comment period shall be 
limited to the substantial new questions that caused its reopening. The 
public notice under Sec. 124.10 shall define the scope of the 
reopening.
    (d) [Reserved]
    (e) Public notice of any of the above actions shall be issued under 
Sec. 124.10.

[48 FR 14264, Apr. 1, 1983, as amended at 49 FR 38051, Sept. 26, 1984; 
65 FR 30911, May 15, 2000]



Sec. 124.15  Issuance and effective date of permit.

    (a) After the close of the public comment period under Sec. 124.10 
on a draft permit, the Regional Administrator shall issue a final permit 
decision (or a decision to deny a permit for the active life of a RCRA 
hazardous waste management facility or unit under Sec. 270.29). The 
Regional Administrator shall notify the applicant and each person who 
has submitted written comments or requested notice of the final permit 
decision. This notice shall include reference to the procedures for 
appealing a decision on a RCRA, UIC, PSD, or NPDES permit under Sec. 
124.19 of this part. For the purposes of this section, a final permit 
decision means a final decision to issue, deny, modify, revoke and 
reissue, or terminate a permit.
    (b) A final permit decision (or a decision to deny a permit for the 
active life of a RCRA hazardous waste management facility or unit under 
Sec. 270.29) shall become effective 30 days after the service of notice 
of the decision unless:
    (1) A later effective date is specified in the decision; or
    (2) Review is requested on the permit under Sec. 124.19.
    (3) No comments requested a change in the draft permit, in which 
case the permit shall become effective immediately upon issuance.

[48 FR 14264, Apr. 1, 1983, as amended at 54 FR 9607, Mar. 7, 1989; 65 
FR 30911, May 15, 2000]



Sec. 124.16  Stays of contested permit conditions.

    (a) Stays. (1) If a request for review of a RCRA, UIC, or NPDES 
permit under Sec. 124.19 of this part is filed, the effect of the 
contested permit conditions shall be stayed and shall not be subject to 
judicial review pending final agency action. Uncontested permit 
conditions shall be stayed only until the date specified in paragraph 
(a)(2)(i) of this section. (No stay of a PSD permit is available under 
this section.) If the permit involves a new facility or new injection 
well, new source, new discharger or a recommencing discharger, the 
applicant shall be without a permit for the proposed new facility, 
injection well, source or discharger pending final agency action. See 
also Sec. 124.60.
    (2)(i) Uncontested conditions which are not severable from those 
contested shall be stayed together with the contested conditions. The 
Regional Administrator shall identify the stayed provisions of permits 
for existing facilities, injection wells, and sources. All other 
provisions of the permit for the existing facility, injection well, or 
source become fully effective and enforceable 30 days after the date of 
the notification required in paragraph (a)(2)(ii) of this section.
    (ii) The Regional Administrator shall, as soon as possible after 
receiving notification from the EAB of the filing of a petition for 
review, notify the EAB, the applicant, and all other interested parties 
of the uncontested (and severable) conditions of the final permit that 
will become fully effective enforceable obligations of the permit as of 
the date specified in paragraph (a)(2)(i) of this section . For NPDES 
permits only, the notice shall comply with the requirements of Sec. 
124.60(b).
    (b) Stays based on cross effects. (1) A stay may be granted based on 
the grounds that an appeal to the Administrator under Sec. 124.19 of 
one permit may result in changes to another EPA-issued permit only when 
each of the permits involved has been appealed to the Administrator.
    (2) No stay of an EPA-issued RCRA, UIC, or NPDES permit shall be 
granted based on the staying of any State-issued permit except at the 
discretion of the Regional Administrator and only upon written request 
from the State Director.
    (c) Any facility or activity holding an existing permit must:
    (1) Comply with the conditions of that permit during any 
modification or

[[Page 337]]

revocation and reissuance proceeding under Sec. 124.5; and
    (2) To the extent conditions of any new permit are stayed under this 
section, comply with the conditions of the existing permit which 
correspond to the stayed conditions, unless compliance with the existing 
conditions would be technologically incompatible with compliance with 
other conditions of the new permit which have not been stayed.

Sec. 124.17  Response to comments.

    (a) (Applicable to State programs, see Sec. Sec. 123.25 (NPDES), 
145.11 (UIC), 233.26 (404), and 271.14 (RCRA).) At the time that any 
final permit decision is issued under Sec. 124.15, the Director shall 
issue a response to comments. States are only required to issue a 
response to comments when a final permit is issued. This response shall:
    (1) Specify which provisions, if any, of the draft permit have been 
changed in the final permit decision, and the reasons for the change; 
and
    (2) Briefly describe and respond to all significant comments on the 
draft permit or the permit application (for section 404 permits only) 
raised during the public comment period, or during any hearing.
    (b) For EPA-issued permits, any documents cited in the response to 
comments shall be included in the administrative record for the final 
permit decision as defined in Sec. 124.18. If new points are raised or 
new material supplied during the public comment period, EPA may document 
its response to those matters by adding new materials to the 
administrative record.
    (c) (Applicable to State programs, see Sec. Sec. 123.25 (NPDES), 
145.11 (UIC), 233.26 (404), and 271.14 (RCRA).) The response to comments 
shall be available to the public.



Sec. 124.18  Administrative record for final permit when EPA is the
permitting authority.

    (a) The Regional Administrator shall base final permit decisions 
under Sec. 124.15 on the administrative record defined in this section.
    (b) The administrative record for any final permit shall consist of 
the administrative record for the draft permit and:
    (1) All comments received during the public comment period provided 
under Sec. 124.10 (including any extension or reopening under Sec. 
124.14);
    (2) The tape or transcript of any hearing(s) held under Sec. 
124.12;
    (3) Any written materials submitted at such a hearing;
    (4) The response to comments required by Sec. 124.17 and any new 
material placed in the record under that section;
    (5) For NPDES new source permits only, final environmental impact 
statement and any supplement to the final EIS;
    (6) Other documents contained in the supporting file for the permit; 
and
    (7) The final permit.
    (c) The additional documents required under paragraph (b) of this 
section should be added to the record as soon as possible after their 
receipt or publication by the Agency. The record shall be complete on 
the date the final permit is issued.
    (d) This section applies to all final RCRA, UIC, PSD, and NPDES 
permits when the draft permit was subject to the administrative record 
requirements of Sec. 124.9 and to all NPDES permits when the draft 
permit was included in a public notice after October 12, 1979.
    (e) Material readily available at the issuing Regional Office, or 
published materials which are generally available and which are included 
in the administrative record under the standards of this section or of 
Sec. 124.17 (``Response to comments''), need not be physically included 
in the same file as the rest of the record as long as it is specifically 
referred to in the statement of basis or fact sheet or in the response 
to comments.



Sec. 124.19  Appeal of RCRA, UIC, NPDES and PSD Permits.

    (a) Petitioning for review of a permit decision. (1) Initiating an 
appeal. Appeal from a RCRA, UIC, NPDES, or PSD final permit decision 
issued under Sec. 124.15 of this part, or a decision to deny a permit 
for the active life of a RCRA hazardous waste management

[[Page 338]]

facility or unit under Sec. 270.29 of this chapter, is commenced by 
filing a petition for review with the Clerk of the Environmental Appeals 
Board within the time prescribed in paragraph (a)(3) of this section.
    (2) Who may file? Any person who filed comments on the draft permit 
or participated in a public hearing on the draft permit may file a 
petition for review as provided in this section. Additionally, any 
person who failed to file comments or failed to participate in the 
public hearing on the draft permit may petition for administrative 
review of any permit conditions set forth in the final permit decision, 
but only to the extent that those final permit conditions reflect 
changes from the proposed draft permit.
    (3) Filing deadline. A petition for review must be filed with the 
Clerk of the Environmental Appeals Board within 30 days after the 
Regional Administrator serves notice of the issuance of a RCRA, UIC, 
NPDES, or PSD final permit decision under Sec. 124.15 or a decision to 
deny a permit for the active life of a RCRA hazardous waste management 
facility or unit under Sec. 270.29 of this chapter. A petition is filed 
when it is received by the Clerk of the Environmental Appeals Board at 
the address specified for the appropriate method of delivery as provided 
in paragraph (i)(2) of this section.
    (4) Petition contents. (i) In addition to meeting the requirements 
in paragraph (d), a petition for review must identify the contested 
permit condition or other specific challenge to the permit decision and 
clearly set forth, with legal and factual support, petitioner's 
contentions for why the permit decision should be reviewed. The petition 
must demonstrate that each challenge to the permit decision is based on:
    (A) A finding of fact or conclusion of law that is clearly 
erroneous, or
    (B) An exercise of discretion or an important policy consideration 
that the Environmental Appeals Board should, in its discretion, review.
    (ii) Petitioners must demonstrate, by providing specific citation or 
other appropriate reference to the administrative record (e.g., by 
including the document name and page number), that each issue being 
raised in the petition was raised during the public comment period 
(including any public hearing) to the extent required by Sec. 124.13. 
For each issue raised that was not raised previously, the petition must 
explain why such issues were not required to be raised during the public 
comment period as provided in Sec. 124.13. Additionally, if the 
petition raises an issue that the Regional Administrator addressed in 
the response to comments document issued pursuant to Sec. 124.17, then 
petitioner must provide a citation to the relevant comment and response 
and explain why the Regional Administrator's response to the comment was 
clearly erroneous or otherwise warrants review.
    (b) Response(s) to a petition for review. (1) In a PSD or other new 
source permit appeal, the Regional Administrator must file a response to 
the petition for review, a certified index of the administrative record, 
and the relevant portions of the administrative record within 21 days 
after the service of the petition. The response brief must respond to 
arguments raised by the appellant, together with specific citation or 
other appropriate reference to the record (e.g., by including the 
document name and page number).
    (2) In all other permit appeals under this section, the Regional 
Administrator must file a response to the petition, a certified index of 
the administrative record, and the relevant portions of the 
administrative record within 30 days after the service of a petition.
    (c) Replies. (1) In PSD and other new source permit appeals, the 
Environmental Appeals Board will apply a presumption against the filing 
of a reply brief. By motion, petitioner may seek leave of the 
Environmental Appeals Board to file a reply to the response, which the 
Environmental Appeals Board, in its discretion, may grant. The motion 
must be filed simultaneously with the proposed reply within 10 days 
after service of the response. In its motion, petitioner must specify 
those arguments in the response to which petitioner seeks to reply and 
the reasons petitioner believes it is necessary to file a reply to those 
arguments. Petitioner may not raise new

[[Page 339]]

issues or arguments in the motion or in the reply.
    (2) In all other permit appeals under this section, petitioner may 
file a reply within 15 days after service of the response. Petitioner 
may not raise new issues or arguments in the reply.
    (d) Content and form of briefs. (1) Content requirements. All briefs 
filed under this section must contain, under appropriate headings:
    (i) A table of contents, with page references;
    (ii) A table of authorities with references to the pages of the 
brief where they are cited;
    (iii) A table of attachments, if required under paragraph (d)(2) of 
this section; and
    (iv) A statement of compliance with the word limitation.
    (2) Attachments. Parts of the record to which the parties wish to 
direct the Environmental Appeals Board's attention may be appended to 
the brief submitted. If the brief includes attachments, a table must be 
included that provides the title of each appended document and assigns a 
label identifying where it may be found (e.g., Excerpts from the 
Response to Comments Document * * * Attachment 1).
    (3) Length. Unless otherwise ordered by the Environmental Appeals 
Board, petitions and response briefs may not exceed 14,000 words, and 
all other briefs may not exceed 7,000 words. Filers may rely on the 
word-processing system used to determine the word count. In lieu of a 
word limitation, filers may comply with a 30-page limit for petitions 
and response briefs, or a 15-page limit for replies. Headings, 
footnotes, and quotations count toward the word limitation. The table of 
contents, table of authorities, table of attachments (if any), statement 
requesting oral argument (if any), statement of compliance with the word 
limitation, and any attachments do not count toward the word limitation. 
The Environmental Appeals Board may exclude any petition, response, or 
other brief that does not meet word limitations. Where a party can 
demonstrate a compelling and documented need to exceed such limitations, 
such party must seek advance leave of the Environmental Appeals Board to 
file a longer brief. Such requests are discouraged and will be granted 
only in unusual circumstances.
    (e) Participation by amicus curiae. Any interested person may file 
an amicus brief in any appeal pending before the Environmental Appeals 
Board under this section. The deadline for filing such brief is 15 days 
after the filing of the response brief, except that amicus briefs in PSD 
or other new source permit appeals must be filed within 21 days after 
the filing of the petition. Amicus briefs must comply with all 
procedural requirements of this section.
    (f) Motions. (1) In general. A request for an order or other relief 
must be made by written motion unless these rules prescribe another 
form.
    (2) Contents of a motion. A motion must state with particularity the 
grounds for the motion, the relief sought, and the legal argument 
necessary to support the motion. In advance of filing a motion, parties 
must attempt to ascertain whether the other party(ies) concur(s) or 
object(s) to the motion and must indicate in the motion the attempt made 
and the response obtained.
    (3) Response to motion. Any party may file a response to a motion. 
Responses must state with particularity the grounds for opposition and 
the legal argument necessary to support the motion. The response must be 
filed within 15 days after service of the motion unless the 
Environmental Appeals Board shortens or extends the time for response.
    (4) Reply. Any reply to a response filed under paragraph (f)(3) of 
this section must be filed within 10 days after service of the response. 
A reply must not introduce any new issues or arguments and may respond 
only to matters presented in the response.
    (5) Length. Unless otherwise ordered by the Environmental Appeals 
Board, motions and any responses or replies may not exceed 7000 words. 
Filers may rely on the word-processing system used to determine the word 
count. In lieu of a word limitation, filers may comply with a 15-page 
limit. Headings, footnotes, and quotations count toward the word or 
page-length limitation. The Environmental Appeals Board may exclude any 
motion that does not meet

[[Page 340]]

word limitations. Where a party can demonstrate a compelling and 
documented need to exceed such limitations, such party must seek advance 
leave of the Environmental Appeals Board. Such requests are discouraged 
and will be granted only in unusual circumstances.
    (6) Disposition of a motion for a procedural order. The 
Environmental Appeals Board may act on a motion for a procedural order 
at any time without awaiting a response.
    (g) Timing of motions for extension of time. Parties must file 
motions for extensions of time sufficiently in advance of the due date 
to allow other parties to have a reasonable opportunity to respond to 
the request for more time and to provide the Environmental Appeals Board 
with a reasonable opportunity to issue an order.
    (h) Oral argument. The Environmental Appeals Board may hold oral 
argument on its own initiative or at its discretion in response to a 
request by one or more of the parties. To request oral argument, a party 
must include in its substantive brief a statement explaining why oral 
argument should be permitted. The Environmental Appeals Board will apply 
a presumption against oral argument in PSD or other new source permit 
appeals. The Environmental Appeals Board may, by order, establish 
additional procedures governing any oral argument before the 
Environmental Appeals Board.
    (i) Filing and service requirements. Documents filed under this 
section, including the petition for review, must be filed with the Clerk 
of the Environmental Appeals Board. A document is filed when it is 
received by the Clerk of the Environmental Appeals Board at the address 
specified for the appropriate method of delivery as provided in 
paragraph (i)(2) of this section. Service of a document between parties 
to an appeal or by the Environmental Appeals Board on a party is 
complete upon mailing for U.S. mail or EPA internal mail, when placed in 
the custody of a reliable commercial delivery service, or upon 
transmission for facsimile or email.
    (1) Caption and other filing requirements. Every document filed with 
the Environmental Appeals Board must specifically identify in the 
caption the permit applicant, the permitted facility, and the permit 
number. All documents that are filed must be signed by the person filing 
the documents or the representative of the person filing the documents. 
Each filing must also indicate the signer's name, address, and telephone 
number, as well as an email address, and facsimile number, if any.
    (2) Method of filing. Unless otherwise permitted under these rules, 
documents must be filed either by using the Environmental Appeals 
Board's electronic filing system, by U.S. mail, or by hand delivery. In 
addition, a motion or a response to a motion may be submitted by 
facsimile if the submission contains no attachments. Upon filing a 
motion or response to a motion by facsimile, the sender must, within one 
business day, submit the original copy to the Clerk of the Environmental 
Appeals Board either electronically, by mail, or by hand-delivery. The 
Environmental Appeals Board may by order require filing by facsimile or 
the Board's electronic filing system, subject to any appropriate 
conditions and limitations.
    (i) Electronic filing. Documents that are filed electronically must 
be submitted using the Environmental Appeals Board's electronic filing 
system, subject to any appropriate conditions and limitations imposed by 
order of the Environmental Appeals Board. All documents filed 
electronically must include the full name of the person filing below the 
signature line. Compliance with Environmental Appeals Board electronic 
filing requirements constitutes compliance with applicable signature 
requirements.
    (ii) Filing by U.S. Mail. Documents that are sent by U.S. Postal 
Service (except by U.S. Express Mail) must be sent to the official 
mailing address of the Clerk of the Environmental Appeals Board at: U.S. 
Environmental Protection Agency, Environmental Appeals Board, 1200 
Pennsylvania Avenue NW., Mail Code 1103M, Washington, DC 20460-0001. The 
original and two copies of each document must be filed. The person 
filing the documents must include a cover letter to the Clerk of the 
Environmental Appeals Board clearly identifying the documents that are

[[Page 341]]

being submitted, the name of the party on whose behalf the documents are 
being submitted, as well as the name of the person filing the documents, 
his or her address, telephone number and, if available, fax number and 
email address.
    (iii) Filing by hand delivery. Documents delivered by hand or 
courier (including deliveries by U.S. Express Mail) must be delivered to 
the Clerk of the Environmental Appeals Board at: U.S. Environmental 
Protection Agency, Environmental Appeals Board, EPA East Building, 1201 
Constitution Avenue NW., Room 3334, Washington, DC 20004. The original 
and two copies of each document must be filed. The person filing the 
documents must include a cover letter to the Clerk of the Environmental 
Appeals Board clearly identifying the documents being submitted, the 
name of the party on whose behalf the documents are being submitted, as 
well as the name of the person filing the documents, his or her address, 
telephone number and, if available, fax number and email address.
    (3) Service--(i) Service information. The first document filed by 
any person shall contain the name, mailing address, telephone number, 
and email address of an individual authorized to receive service 
relating to the proceeding. Parties shall promptly file any changes in 
this information with the Clerk of the Environmental Appeals Board, and 
serve copies on all parties to the proceeding. If a party fails to 
furnish such information and any changes thereto, service to the party's 
last known address shall satisfy the requirements of paragraph (i)(3) of 
this section.
    (ii) Service requirements for parties. Petitioner must serve the 
petition for review on the Regional Administrator and the permit 
applicant (if the applicant is not the petitioner). Once an appeal is 
docketed, every document filed with the Environmental Appeals Board must 
be served on all other parties. Service must be by first class U.S. 
mail, by any reliable commercial delivery service, or, if agreed to by 
the parties, by facsimile or other electronic means, including but not 
necessarily limited to or email. A party who consents to service by 
facsimile or other electronic means must file an acknowledgement of its 
consent (identifying the type of electronic means agreed to and the 
electronic address to be used) with the Clerk of the Environmental 
Appeals Board. The Environmental Appeals Board may by order authorize or 
require service by facsimile, email, or other electronic means, subject 
to any appropriate conditions and limitations.
    (iii) Service of rulings, orders, and decisions. The Clerk of the 
Environmental Appeals Board must serve copies of rulings, orders, and 
decisions on all parties. Service may be made by U.S. mail (including by 
certified mail or return receipt requested, Overnight Express and 
Priority Mail), EPA's internal mail, any reliable commercial delivery 
service, or electronic means (including but not necessarily limited to 
facsimile and email).
    (4) Proof of service. A certificate of service must be appended to 
each document filed stating the names of persons served, the date and 
manner of service, as well as the electronic, mailing, or hand delivery 
address, or facsimile number, as appropriate.
    (j) Withdrawal of permit or portions of permit by Regional 
Administrator. The Regional Administrator, at any time prior to 30 days 
after the Regional Administrator files its response to the petition for 
review under paragraph (b) of this section, may, upon notification to 
the Environmental Appeals Board and any interested parties, withdraw the 
permit and prepare a new draft permit under Sec. 124.6 addressing the 
portions so withdrawn. The new draft permit must proceed through the 
same process of public comment and opportunity for a public hearing as 
would apply to any other draft permit subject to this part. Any portions 
of the permit that are not withdrawn and that are not stayed under Sec. 
124.16(a) continue to apply. If the Environmental Appeals Board has held 
oral argument, the Regional Administrator may not unilaterally withdraw 
the permit, but instead must request that the Environmental Appeals 
Board grant a voluntary remand of the permit or any portion thereof.

[[Page 342]]

    (k) Petitioner request for dismissal of petition. Petitioner, by 
motion, may request to have the Environmental Appeals Board dismiss its 
appeal. The motion must briefly state the reason for its request.
    (l) Final disposition and judicial review. (1) A petition to the 
Environmental Appeals Board under paragraph (a) of this section is, 
under 5 U.S.C. 704, a prerequisite to seeking judicial review of the 
final agency action.
    (2) For purposes of judicial review under the appropriate Act, final 
agency action on a RCRA, UIC, NPDES, or PSD permit occurs when agency 
review procedures under this section are exhausted and the Regional 
Administrator subsequently issues a final permit decision under this 
paragraph. A final permit decision must be issued by the Regional 
Administrator:
    (i) When the Environmental Appeals Board issues notice to the 
parties that the petition for review has been denied;
    (ii) When the Environmental Appeals Board issues a decision on the 
merits of the appeal and the decision does not include a remand of the 
proceedings; or
    (iii) Upon the completion of remand proceedings if the proceedings 
are remanded, unless the Environmental Appeals Board's remand order 
specifically provides that appeal of the remand decision will be 
required to exhaust administrative remedies.
    (3) The Regional Administrator must promptly publish notice of any 
final agency action regarding a PSD permit in the Federal Register.
    (m) Motions for reconsideration or clarification. Motions to 
reconsider or clarify any final disposition of the Environmental Appeals 
Board must be filed within 10 days after service of that order. Motions 
for reconsideration must set forth the matters claimed to have been 
erroneously decided and the nature of the alleged errors. Motions for 
clarification must set forth with specificity the portion of the 
decision for which clarification is being sought and the reason 
clarification is necessary. Motions for reconsideration or clarification 
under this provision must be directed to, and decided by, the 
Environmental Appeals Board. Motions for reconsideration or 
clarification directed to the Administrator, rather than the 
Environmental Appeals Board, will not be considered, unless such motion 
relates to a matter that the Environmental Appeals Board has referred to 
the Administrator pursuant to Sec. 124.2 and for which the 
Administrator has issued the final order. A motion for reconsideration 
or clarification does not stay the effective date of the final order 
unless the Environmental Appeals Board specifically so orders.
    (n) Board authority. In exercising its duties and responsibilities 
under this part, the Environmental Appeals Board may do all acts and 
take all measures necessary for the efficient, fair, and impartial 
adjudication of issues arising in an appeal under this part including, 
but not limited to, imposing procedural sanctions against a party who, 
without adequate justification, fails or refuses to comply with this 
part or an order of the Environmental Appeals Board. Such sanctions may 
include drawing adverse inferences against a party, striking a party's 
pleadings or other submissions from the record, and denying any or all 
relief sought by the party in the proceeding. Additionally, for good 
cause, the Board may relax or suspend the filing requirements prescribed 
by these rules or Board order.
    (o) General NPDES permits. (1) Persons affected by an NPDES general 
permit may not file a petition under this section or otherwise challenge 
the conditions of a general permit in further Agency proceedings. 
Instead, they may do either of the following:
    (i) Challenge the general permit by filing an action in court; or
    (ii) Apply for an individual NPDES permit under Sec. 122.21 as 
authorized in Sec. 122.28 of this chapter and may then petition the 
Environmental Appeals Board to review the individual permit as provided 
by this section.
    (2) As provided in Sec. 122.28(b)(3) of this chapter, any 
interested person may also petition the Director to require an 
individual NPDES permit for any discharger eligible for authorization to 
discharge under an NPDES general permit.
    (p) The Environmental Appeals Board also may decide on its own 
initiative to review any condition of any RCRA, UIC, NPDES, or PSD 
permit decision

[[Page 343]]

issued under this part for which review is available under paragraph (a) 
of this section. The Environmental Appeals Board must act under this 
paragraph within 30 days of the service date of notice of the Regional 
Administrator's action.

Sec. 124.20  Computation of time.

    (a) Any time period scheduled to begin on the occurrence of an act 
or event shall begin on the day after the act or event.
    (b) Any time period scheduled to begin before the occurrence of an 
act or event shall be computed so that the period ends on the day before 
the act or event.
    (c) If the final day of any time period falls on a weekend or legal 
holiday, the time period shall be extended to the next working day.
    (d) When a party or interested person may or must act within a 
prescribed period after being served and service is made by U.S. mail, 
EPA's internal mail, or reliable commercial delivery service, 3 days 
shall be added to the prescribed time. The prescribed period for acting 
after being served is not expanded by 3 days when service is made by 
personal delivery, facsimile, or email.

the appeal, and any hearing or other proceedings on remand if the Board 
so orders, shall proceed pursuant to the procedures of this part as in 
effect on June 13, 2000.
    (3) For any NPDES permit decision for which a request for 
evidentiary hearing was filed on or prior to June 13, 2000 but was 
neither granted nor denied prior to that date, the Regional 
Administrator shall, no later than July 14, 2000, notify the requester 
that the request for evidentiary hearing is being returned without 
prejudice. Notwithstanding the time limit in Sec. 124.19(a), the 
requester may file an appeal with the Board, in accordance with the

Sec. 124.31  Pre-application public meeting and notice.

    (a) Applicability. The requirements of this section shall apply to 
all RCRA part B applications seeking initial permits for hazardous waste 
management units over which EPA has permit issuance authority. The 
requirements of this section shall also apply to RCRA part B 
applications seeking renewal of permits for such units, where the 
renewal application is proposing a significant change in facility 
operations. For the purposes of this section, a ``significant change'' 
is any change that would qualify as a class 3 permit modification under 
40 CFR 270.42. For the purposes of this section only, ``hazardous waste 
management units over which EPA has permit issuance authority'' refers 
to hazardous waste management units for which the State where the units 
are located has not been authorized to issue RCRA permits pursuant to 40 
CFR part 271. The requirements of this section shall also apply to 
hazardous waste management facilities for which facility owners or 
operators are seeking coverage under a RCRA standardized permit (see 40 
part 270, subpart J), including renewal of a standardized permit for 
such units, where the renewal is proposing a significant change in 
facility operations, as defined at Sec. 124.211(c). The requirements of 
this section do not apply to permit modifications under 40 CFR 270.42 or 
to applications that are submitted for the sole purpose of conducting 
post-closure activities or post-closure activities and corrective action 
at a facility.
    (b) Prior to the submission of a part B RCRA permit application for 
a facility, or to the submission of a written Notice of Intent to be 
covered by a RCRA standardized permit (see 40 CFR part 270, subpart J), 
the applicant must hold at least one meeting with the public in order to 
solicit questions from the community and inform the community of 
proposed hazardous waste management activities. The applicant shall post 
a sign-in sheet or otherwise provide a voluntary opportunity for 
attendees to provide their names and addresses.
    (c) The applicant shall submit a summary of the meeting, along with 
the list of attendees and their addresses developed under paragraph (b) 
of this section, and copies of any written comments or materials 
submitted at the meeting, to the permitting agency as a part of the part 
B application, in accordance with 40 CFR 270.14(b), or with the written 
Notice of Intent to be covered by a RCRA standardized permit (see 40 CFR 
part 270, subpart J).
    (d) The applicant must provide public notice of the pre-application 
meeting at least 30 days prior to the meeting. The applicant must 
maintain, and provide to the permitting agency upon request, 
documentation of the notice.

following forms:
    (i) A newspaper advertisement. The applicant shall publish a notice, 
fulfilling the requirements in paragraph (d)(2) of this section, in a 
newspaper of general circulation in the county or equivalent 
jurisdiction that hosts the proposed location of the facility. In 
addition, the Director shall instruct the applicant to publish the 
notice in newspapers of general circulation in adjacent counties or 
equivalent jurisdictions, where the Director determines that such 
publication is necessary to inform the affected public. The notice must 
be published as a display advertisement.
    (ii) A visible and accessible sign. The applicant shall post a 
notice on a clearly marked sign at or near the facility, fulfilling the 
requirements in paragraph (d)(2) of this section. If the applicant

enough to be readable from the nearest point where the public would pass 
by the site.
    (iii) A broadcast media announcement. The applicant shall broadcast 
a notice, fulfilling the requirements in paragraph (d)(2) of this 
section, at least once on at least one local radio station or television 
station. The applicant may employ another medium with prior approval of 
the Director.
    (iv) A notice to the permitting agency. The applicant shall send a 
copy of the newspaper notice to the permitting agency and to the 
appropriate units of State and local government, in accordance with 
Sec. 124.10(c)(1)(x).

[[Page 345]]

    (2) The notices required under paragraph (d)(1) of this section must 
include:
    (i) The date, time, and location of the meeting;
    (ii) A brief description of the purpose of the meeting;

management units over which EPA has permit issuance authority'' refers 
to hazardous waste management units for which the State where the units 
are located has not been authorized to issue RCRA permits pursuant to 40 
CFR part 271. The requirements of this section do not apply to hazardous 
waste units for which facility owners or operators are seeking coverage 
under a RCRA standardized permit (see 40 CFR part 270, subpart J)). The 
requirements of this section also do not apply to permit modifications 
under 40 CFR 270.42 or permit applications submitted for the sole 
purpose of conducting post-closure activities or post-closure activities 
and corrective action at a facility.

facility mailing list;
    (iv) The location where copies of the permit application and any 
supporting documents can be viewed and copied;
    (v) A brief description of the facility and proposed operations, 
including the address or a map (e.g., a sketched or copied street map) 
of the facility location on the front page of the notice; and
    (vi) The date that the application was submitted.
    (c) Concurrent with the notice required under Sec. 124.32(b) of 
this subpart, the Director must place the permit application and any 
supporting documents in a location accessible to the public in the 
vicinity of the facility or at the permitting agency's office.

[60 FR 63431, Dec. 11, 1995, as amended at 70 FR 53449, Sept. 8, 2005]



Sec. 124.33  Information repository.

    (a) Applicability. The requirements of this section apply to all 
applications seeking RCRA permits for hazardous waste management units 
over which EPA has permit issuance authority. For the purposes of this 
section only, ``hazardous waste management units over which EPA has 
permit issuance authority'' refers to hazardous waste management units 
for which the State where the units are located has not been authorized 
to issue RCRA permits pursuant to 40 CFR part 271.
    (b) The Director may assess the need, on a case-by-case basis, for 
an information repository. When assessing the need for an information 
repository, the

[[Page 346]]

Director shall consider a variety of factors, including: the level of 
public interest; the type of facility; the presence of an existing 
repository; and the proximity to the nearest copy of the administrative 
record. If the Director determines, at any time after submittal of a 
permit application, that there is a need for a repository, then the 
Director shall notify the facility that it must establish and maintain 
an information repository. (See 40 CFR 270.30(m) for similar provisions 
relating to the information repository during the life of a permit).
    (c) The information repository shall contain all documents, reports, 
data, and information deemed necessary by the Director to fulfill the 
purposes for which the repository is established. The Director shall 
have the discretion to limit the contents of the repository.
    (d) The information repository shall be located and maintained at a 
site chosen by the facility. If the Director finds the site unsuitable 
for the purposes and persons for which it was established, due to 
problems with the location, hours of availability, access, or other 
relevant considerations, then the Director shall specify a more 
appropriate site.
    (e) The Director shall specify requirements for informing the public 
about the information repository. At a minimum, the Director shall 
require the facility to provide a written notice about the information 
repository to all individuals on the facility mailing list.
    (f) The facility owner/operator shall be responsible for maintaining 
and updating the repository with appropriate information throughout a 
time period specified by the Director. The Director may close the 
repository at his or her discretion, based on the factors in paragraph 
(b) of this section.

public comment period under Sec. 124.10 or Sec. 124.118. (40 CFR 
52.21(q)(3) provides for denial of a PSD permit to a facility or 
activity when the Federal Land Manager demonstrates that its emissions 
would adversely affect a Class I area even though the applicable 
increments would not be exceeded. 40 CFR 52.21(q)(4) conversely 
authorizes EPA, with the concurrence of the Federal Land Manager and 
State responsible, to grant certain variances from the otherwise 
applicable emission limitations to a facility or activity whose 
emissions would affect a Class I area.)
    (c) Variances authorized by 40 CFR 52.21 (q)(5) through (q)(7) shall 
be handled as specified in those paragraphs and shall not be subject to 
this part. Upon receiving appropriate documentation of a variance 
properly granted under any of these provisions, the Regional 
Administrator shall enter the variance in the administrative record. Any 
decisions later made in proceedings under this part concerning that 
permit shall be consistent with the conditions of that variance.



        Subpart D_Specific Procedures Applicable to NPDES Permits



Sec. 124.51  Purpose and scope.

    (a) This subpart sets forth additional requirements and procedures 
for decisionmaking for the NPDES program.
    (b) Decisions on NPDES variance requests ordinarily will be made 
during the permit issuance process. Variances and other changes in 
permit conditions ordinarily will be decided through the same notice-
and-comment and hearing procedures as the basic permit.
    (c) As stated in 40 CFR 131.4, an Indian Tribe that meets the 
statutory criteria which authorize EPA to treat the Tribe in a manner 
similar to that in which it treats a State for purposes of the Water 
Quality Standards program is likewise qualified for such treatment for 
purposes of State certification of water quality standards pursuant to 
section 401(a)(1) of the Act and subpart D of this part.

FR 64343, Dec. 14, 1994]



Sec. 124.52  Permits required on a case-by-case basis.

    (a) Various sections of part 122, subpart B allow the Director to 
determine, on a case-by-case basis, that certain concentrated animal 
feeding operations (Sec. 122.23), concentrated aquatic animal 
production facilities (Sec. l22.24), storm water discharges (Sec. 
122.26), and certain other facilities covered by general permits (Sec. 
122.28) that do not generally require an individual permit may be 
required to obtain an individual permit because of their contributions 
to water pollution.
    (b) Whenever the Regional Administrator decides that an individual 
permit is required under this section, except as provided in paragraph 
(c) of this section, the Regional Administrator shall notify the 
discharger in

[[Page 348]]

writing of that decision and the reasons for it, and shall send an 
application form with the notice. The discharger must apply for a permit 
under Sec. 122.21 within 60 days of notice, unless permission for a 
later date is granted by the Regional Administrator. The question 
whether the designation was proper will remain open for consideration 
during the public comment period under Sec. 124.11 and in any 
subsequent hearing.
    (c) Prior to a case-by-case determination that an individual permit 
is required for a storm water discharge under this section (see Sec. 
122.26(a)(1)(v), (c)(1)(v), and (a)(9)(iii) of this chapter), the 
Regional Administrator may require the discharger to submit a permit 
application or other information regarding the discharge under section 
308 of the CWA. In requiring such information, the Regional 
Administrator shall notify the discharger in writing and shall send an 
application form with the notice. The discharger must apply for a permit 
within 180 days of notice, unless permission for a later date is granted 
by the Regional Administrator. The question whether the initial 
designation was proper will remain open for consideration during the 
public comment period under Sec. 124.11 and in any subsequent hearing.

1999; 65 FR 30912, May 15, 2000]



Sec. 124.53  State certification.

    (a) Under CWA section 401(a)(1), EPA may not issue a permit until a 
certification is granted or waived in accordance with that section by 
the State in which the discharge originates or will originate.
    (b) Applications received without a State certification shall be 
forwarded by the Regional Administrator to the certifying State agency 
with a request that certification be granted or denied.
    (c) If State certification has not been received by the time the 
draft permit is prepared, the Regional Administrator shall send the 
certifying State agency:
    (1) A copy of a draft permit;
    (2) A statement that EPA cannot issue or deny the permit until the 
certifying State agency has granted or denied certification under Sec. 
124.55, or waived its right to certify; and
    (3) A statement that the State will be deemed to have waived its 
right to certify unless that right is exercised within a specified 
reasonable time not to exceed 60 days from the date the draft permit is 
mailed to the certifying State agency unless the Regional Administrator 
finds that unusual circumstances require a longer time.
    (d) State certification shall be granted or denied within the 
reasonable time specified under paragraph (c)(3) of this section. The 
State shall send a notice of its action, including a copy of any 
certification, to the applicant and the Regional Administrator.
    (e) State certification shall be in writing and shall include:
    (1) Conditions which are necessary to assure compliance with the 
applicable provisions of CWA sections 208(e), 301, 302, 303, 306, and 
307 and with appropriate requirements of State law;
    (2) When the State certifies a draft permit instead of a permit 
application, any conditions more stringent than those in the draft 
permit which the State finds necessary to meet the requirements listed 
in paragraph (e)(1) of this section. For each more stringent condition, 
the certifying State agency shall cite the CWA or State law references 
upon which that condition is based. Failure to provide such a citation 
waives the right to certify with respect to that condition; and
    (3) A statement of the extent to which each condition of the draft 
permit can be made less stringent without violating the requirements of 
State law, including water quality standards. Failure to provide this 
statement for any condition waives the right to certify or object to any 
less stringent condition which may be established during the EPA permit 
issuance process.



Sec. 124.54  Special provisions for State certification and 
concurrence on applications for section 301(h) variances.

    (a) When an application for a permit incorporating a variance 
request under CWA section 301(h) is submitted to a State, the 
appropriate State official shall either:

[[Page 349]]

    (1) Deny the request for the CWA section 301(h) variance (and so 
notify the applicant and EPA) and, if the State is an approved NPDES 
State and the permit is due for reissuance, process the permit 
application under normal procedures; or
    (2) Forward a certification meeting the requirements of Sec. 124.53 
to the Regional Administrator.
    (b) When EPA issues a tentative decision on the request for a 
variance under CWA section 301(h), and no certification has been 
received under paragraph (a) of this section, the Regional Administrator 
shall forward the tentative decision to the State in accordance with 
Sec. 124.53(b) specifying a reasonable time for State certification and 
concurrence. If the State fails to deny or grant certification and 
concurrence under paragraph (a) of this section within such reasonable 
time, certification shall be waived and the State shall be deemed to 
have concurred in the issuance of a CWA section 301(h) variance.
    (c) Any certification provided by a State under paragraph (a)(2) of 
this section shall constitute the State's concurrence (as required by 
section 301(h)) in the issuance of the permit incorporating a section 
301(h) variance subject to any conditions specified therein by the 
State. CWA section 301(h) certification and concurrence under this 
section will not be forwarded to the State by EPA for recertification 
after the permit issuance process; States must specify any conditions 
required by State law, including water quality standards, in the initial 
certification.



Sec. 124.55  Effect of State certification.

    (a) When certification is required under CWA section 401(a)(1) no 
final permit shall be issued:
    (1) If certification is denied, or
    (2) Unless the final permit incorporates the requirements specified 
in the certification under Sec. 124.53(e).
    (b) If there is a change in the State law or regulation upon which a 
certification is based, or if a court of competent jurisdiction or 
appropriate State board or agency stays, vacates, or remands a 
certification, a State which has issued a certification under Sec. 
124.53 may issue a modified certification or notice of waiver and 
forward it to EPA. If the modified certification is received before 
final agency action on the permit, the permit shall be consistent with 
the more stringent conditions which are based upon State law identified 
in such certification. If the certification or notice of waiver is 
received after final agency action on the permit, the Regional 
Administrator may modify the permit on request of the permittee only to 
the extent necessary to delete any conditions based on a condition in a 
certification invalidated by a court of competent jurisdiction or by an 
appropriate State board or agency.
    (c) A State may not condition or deny a certification on the grounds 
that State law allows a less stringent permit condition. The Regional 
Administrator shall disregard any such certification conditions, and 
shall consider those conditions or denials as waivers of certification.
    (d) A condition in a draft permit may be changed during agency 
review in any manner consistent with a certification meeting the 
requirements of Sec. 124.53(e). No such changes shall require EPA to 
submit the permit to the State for recertification.
    (e) Review and appeals of limitations and conditions attributable to 
State certification shall be made through the applicable procedures of 
the State and may not be made through the procedures in this part.
    (f) Nothing in this section shall affect EPA's obligation to comply 
with Sec. 122.47. See CWA section 301(b)(1)(C).

[48 FR 14264, Apr. 1, 1983, as amended at 65 FR 30912, May 15, 2000]



Sec. 124.56  Fact sheets.

    (Applicable to State programs, see Sec. 123.25 (NPDES).) In 
addition to meeting the requirements of Sec. 124.8, NPDES fact sheets 
shall contain the following:
    (a) Any calculations or other necessary explanation of the 
derivation of specific effluent limitations and conditions or standards 
for sewage sludge use or disposal, including a citation to the 
applicable effluent limitation guideline, performance standard, or 
standard for sewage sludge use or disposal as required by Sec. 122.44

this chapter;
    (iv) Limitations set on a case-by-case basis under Sec. 125.3 
(c)(2) or (c)(3) of this chapter, or pursuant to Section 405(d)(4) of 
the CWA;
    (v) Limitations to meet the criteria for permit issuance under Sec. 
122.4(i) of this chapter, or
    (vi) Waivers from monitoring requirements granted under Sec. 
122.44(a) of this chapter.
    (2) For every permit to be issued to a treatment works owned by a 
person other than a State or municipality, an explanation of the 
Director's decision on regulation of users under Sec. 122.44(m).
    (c) When appropriate, a sketch or detailed description of the 
location of the discharge or regulated activity described in the 
application; and
    (d) For EPA-issued NPDES permits, the requirements of any State 
certification under Sec. 124.53.
    (e) For permits that include a sewage sludge land application plan

Sec. 124.57  Public notice.

    (a) Section 316(a) requests (applicable to State programs, see Sec. 
123.25). In addition to the information required under Sec. 
124.10(d)(1), public notice of an NPDES draft permit for a discharge 
where a CWA section 316(a) request has been filed under Sec. 122.21(l) 
shall include:
    (1) A statement that the thermal component of the discharge is 
subject to effluent limitations under CWA section 301 or 306 and a brief 
description, including a quantitative statement, of the thermal effluent 
limitations proposed under section 301 or 306;
    (2) A statement that a section 316(a) request has been filed and 
that alternative less stringent effluent limitations may be imposed on 
the thermal component of the discharge under section 316(a) and a brief 
description, including a quantitative statement, of the alternative 
effluent limitations, if any, included in the request; and
    (3) If the applicant has filed an early screening request under 
Sec. 125.72 for a section 316(a) variance, a statement that the 
applicant has submitted such a plan.

Sec. 124.58  [Reserved]



Sec. 124.59  Conditions requested by the Corps of Engineers and other
government agencies.

    (Applicable to State programs, see Sec. 123.25 (NPDES).)
    (a) If during the comment period for an NPDES draft permit, the 
District Engineer advises the Director in writing that anchorage and 
navigation of any of the waters of the United States would be 
substantially impaired by the granting of a permit, the permit shall be 
denied and the applicant so notified. If the District Engineer advised 
the Director that imposing specified conditions upon the permit is 
necessary to avoid any substantial impairment of anchorage or 
navigation, then the Director shall include the specified conditions in 
the permit. Review or appeal of denial of a permit or of conditions 
specified by the District Engineer shall be made through the applicable 
procedures of the Corps of Engineers, and may not be made through the 
procedures provided in this part. If the conditions are stayed by a 
court of competent jurisdiction or by applicable procedures of the Corps 
of Engineers, those conditions shall be considered stayed in the NPDES 
permit for the duration of that stay.
    (b) If during the comment period the U.S. Fish and Wildlife Service, 
the National Marine Fisheries Service, or any other State or Federal 
agency with jurisdiction over fish, wildlife, or public

[[Page 351]]

health advises the Director in writing that the imposition of specified 
conditions upon the permit is necessary to avoid substantial impairment 
of fish, shellfish, or wildlife resources, the Director may include the 
specified conditions in the permit to the extent they are determined 
necessary to carry out the provisions of Sec. 122.49 and of the CWA.
    (c) In appropriate cases the Director may consult with one or more 
of the agencies referred to in this section before issuing a draft 
permit and may reflect their views in the statement of basis, the fact 
sheet, or the draft permit.

[48 FR 14264, Apr. 1, 1983, as amended at 54 FR 258, Jan. 4, 1989]



Sec. 124.60  Issuance and effective date and stays of NPDES permits.

    In addition to the requirements of Sec. Sec. 124.15, 124.16, and 
124.19, the following provisions apply to NPDES permits:
    (a) Notwithstanding the provisions of Sec. 124.16(a)(1), if, for 
any offshore or coastal mobile exploratory drilling rig or coastal 
mobile developmental drilling rig which has never received a final 
effective permit to discharge at a ``site,'' but which is not a ``new 
discharger'' or a ``new source,'' the Regional Administrator finds that 
compliance with certain permit conditions may be necessary to avoid 
irreparable environmental harm during the administrative review, he or 
she may specify in the statement of basis or fact sheet that those 
conditions, even if contested, shall remain enforceable obligations of 
the discharger during administrative review.
    (b)(1) As provided in Sec. 124.16(a), if an appeal of an initial 
permit decision is filed under Sec. 124.19, the force and effect of the 
contested conditions of the final permit shall be stayed until final 
agency action under Sec. 124.19(k)(2). The Regional Administrator shall 
notify, in accordance with Sec. 124.16(a)(2)(ii), the discharger and 
all interested parties of the uncontested conditions of the final permit 
that are enforceable obligations of the discharger.
    (2) When effluent limitations are contested, but the underlying 
control technology is not, the notice shall identify the installation of 
the technology in accordance with the permit compliance schedules (if 
uncontested) as an uncontested, enforceable obligation of the permit.
    (3) When a combination of technologies is contested, but a portion 
of the combination is not contested, that portion shall be identified as 
uncontested if compatible with the combination of technologies proposed 
by the requester.
    (4) Uncontested conditions, if inseverable from a contested 
condition, shall be considered contested.
    (5) Uncontested conditions shall become enforceable 30 days after 
the date of notice under paragraph (b)(1) of this section.
    (6) Uncontested conditions shall include:
    (i) Preliminary design and engineering studies or other requirements 
necessary to achieve the final permit conditions which do not entail 
substantial expenditures;
    (ii) Permit conditions which will have to be met regardless of the 
outcome of the appeal under Sec. 124.19;
    (iii) When the discharger proposed a less stringent level of 
treatment than that contained in the final permit, any permit conditions 
appropriate to meet the levels proposed by the discharger, if the 
measures required to attain that less stringent level of treatment are 
consistent with the measures required to attain the limits proposed by 
any other party; and
    (iv) Construction activities, such as segregation of waste streams 
or installation of equipment, which would partially meet the final 
permit conditions and could also be used to achieve the discharger's 
proposed alternative conditions.
    (c) In addition to the requirements of Sec. 124.16(c)(2), when an 
appeal is filed under Sec. 124.19 on an application for a renewal of an 
existing permit and upon written request from the applicant, the 
Regional Administrator may delete requirements from the existing permit 
which unnecessarily duplicate uncontested provisions of the new permit.

Sec. 124.61  Final environmental impact statement.

    No final NPDES permit for a new source shall be issued until at 
least 30 days after the date of issuance of a final environmental impact 
statement if one is required under 40 CFR 6.805.



Sec. 124.62  Decision on variances.

    (Applicable to State programs, see Sec. 123.25 (NPDES).)
    (a) The Director may grant or deny requests for the following 
variances (subject to EPA objection under Sec. 123.44 for State 
permits):
    (1) Extensions under CWA section 301(i) based on delay in completion 
of a publicly owned treatment works;
    (2) After consultation with the Regional Administrator, extensions 
under CWA section 301(k) based on the use of innovative technology; or
    (3) Variances under CWA section 316(a) for thermal pollution.
    (b) The State Director may deny, or forward to the Regional 
Administrator with a written concurrence, or submit to EPA without 
recommendation a completed request for:
    (1) A variance based on the economic capability of the applicant 
under CWA section 301(c); or
    (2) A variance based on water quality related effluent limitations 
under CWA section 302(b)(2).
    (c) The Regional Administrator may deny, forward, or submit to the 
EPA Office Director for Water Enforcement and Permits with a 
recommendation for approval, a request for a variance listed in 
paragraph (b) of this section that is forwarded by the State Director, 
or that is submitted to the Regional Administrator by the requester 
where EPA is the permitting authority.
    (d) The EPA Office Director for Water Enforcement and Permits may 
approve or deny any variance request submitted under paragraph (c) of 
this section. If the Office Director approves the variance, the Director 
may prepare a draft permit incorporating the variance. Any public notice 
of a draft permit for which a variance or modification has been approved 
or denied shall identify the applicable procedures for appealing that 
decision under Sec. 124.64.
    (e) The State Director may deny or forward to the Administrator (or 
his delegate) with a written concurrence a completed request for:
    (1) A variance based on the presence of ``fundamentally different 
factors'' from those on which an effluent limitations guideline was 
based;
    (2) A variance based upon certain water quality factors under CWA 
section 301(g).
    (f) The Administrator (or his delegate) may grant or deny a request 
for a variance listed in paragraph (e) of this section that is forwarded 
by the State Director, or that is submitted to EPA by the requester 
where EPA is the permitting authority. If the Administrator (or his 
delegate) approves the variance, the State Director or Regional 
Administrator may prepare a draft permit incorporating the variance. Any 
public notice of a draft permit for which a variance or modification has 
been approved or denied shall identify the applicable procedures for 
appealing that decision under Sec. 124.64.

[48 FR 14264, Apr. 1, 1983; 50 FR 6941, Feb. 19, 1985, as amended at 51 
FR 16030, Apr. 30, 1986; 54 FR 256, 258, Jan. 4, 1989]



Sec. 124.63  Procedures for variances when EPA is the permitting
authority.

    (a) In States where EPA is the permit issuing authority and a 
request for a variance is filed as required by Sec. 122.21, the request 
shall be processed as follows:
    (1)(i) If, at the time, that a request for a variance based on the 
presence of fundamentally different factors or on section 301(g) of the 
CWA is submitted, the Regional Administrator has received an application 
under Sec. 124.3 for issuance or renewal of that permit, but has not 
yet prepared a draft permit under Sec. 124.6 covering the discharge in 
question, the Administrator (or his delegate) shall give notice of a 
tentative decision on the request at the time the notice of the draft 
permit is prepared as specified in Sec. 124.10, unless this would 
significantly delay the processing of the permit. In that case the 
processing of the variance request may be separated from the permit in 
accordance with paragraph (a)(3) of this

[[Page 353]]

section, and the processing of the permit shall proceed without delay.
    (ii) If, at the time, that a request for a variance under sections 
301(c) or 302(b)(2) of the CWA is submitted, the Regional Administrator 
has received an application under Sec. 124.3 for issuance or renewal of 
that permit, but has not yet prepared a draft permit under Sec. 124.6 
covering the discharge in question, the Regional Administrator, after 
obtaining any necessary concurrence of the EPA Deputy Assistant 
Administrator for Water Enforcement under Sec. 124.62, shall give 
notice of a tentative decision on the request at the time the notice of 
the draft permit is prepared as specified in Sec. 124.10, unless this 
would significantly delay the processing of the permit. In that case the 
processing of the variance request may be separated from the permit in 
accordance with paragraph (a)(3) of this section, and the processing of 
the permit shall proceed without delay.
    (2) If, at the time that a request for a variance is filed the 
Regional Administrator has given notice under Sec. 124.10 of a draft 
permit covering the discharge in question, but that permit has not yet 
become final, administrative proceedings concerning that permit may be 
stayed and the Regional Administrator shall prepare a new draft permit 
including a tentative decision on the request, and the fact sheet 
required by Sec. 124.8. However, if this will significantly delay the 
processing of the existing draft permit or the Regional Administrator, 
for other reasons, considers combining the variance request and the 
existing draft permit inadvisable, the request may be separated from the 
permit in accordance with paragraph (a)(3) of this section, and the 
administrative disposition of the existing draft permit shall proceed 
without delay.
    (3) If the permit has become final and no application under Sec. 
124.3 concerning it is pending or if the variance request has been 
separated from a draft permit as described in paragraphs (a) (1) and (2) 
of this section, the Regional Administrator may prepare a new draft 
permit and give notice of it under Sec. 124.10. This draft permit shall 
be accompanied by the fact sheet required by Sec. 124.8 except that the 
only matters considered shall relate to the requested variance.

Sec. 124.64  Appeals of variances.

    (a) When a State issues a permit on which EPA has made a variance 
decision, separate appeals of the State permit and of the EPA variance 
decision are possible. If the owner or operator is challenging the same 
issues in both proceedings, the Regional Administrator will decide, in 
consultation with State officials, which case will be heard first.
    (b) Variance decisions made by EPA may be appealed under the 
provisions of Sec. 124.19.
    (c) Stays for section 301(g) variances. If an appeal is filed under 
Sec. 124.19 of a variance requested under CWA section 301(g), any 
otherwise applicable standards and limitations under CWA section 301 
shall not be stayed unless:
    (1) In the judgment of the Regional Administrator, the stay or the 
variance sought will not result in the discharge of pollutants in 
quantities which may reasonably be anticipated to pose an unacceptable 
risk to human health or the environment because of bioaccumulation, 
persistency in the environment, acute toxicity, chronic toxicity, or 
synergistic propensities; and
    (2) In the judgment of the Regional Administrator, there is a 
substantial likelihood that the discharger will succeed on the merits of 
its appeal; and
    (3) The discharger files a bond or other appropriate security which 
is required by the Regional Administrator to assure timely compliance 
with the requirements from which a variance is sought in the event that 
the appeal is unsuccessful.
    (d) Stays for variances other than section 301(g) variances are 
governed by Sec. Sec. 124.16 and 124.60.

Sec. 124.66  Special procedures for decisions on thermal variances 
under section 316(a).

    (a) The only issues connected with issuance of a particular permit 
on which EPA will make a final Agency decision before the final permit 
is issued under Sec. Sec. 124.15 and 124.60 are whether alternative 
effluent limitations would be justified under CWA section 316(a) and 
whether cooling water intake structures will use the best available 
technology under section 316(b). Permit applicants who wish an early 
decision on these issues should request it and furnish supporting 
reasons at the time their permit applications are filed under Sec. 
122.21. The Regional Administrator will then decide whether or not to 
make an early decision. If it is granted, both the early decision on CWA 
section 316 (a) or (b) issues and the grant of the balance of the permit 
shall be considered permit issuance under these regulations, and shall 
be subject to the same requirements of public notice and comment and the 
same opportunity for an appeal under Sec. 124.19.
    (b) If the Regional Administrator, on review of the administrative 
record, determines that the information necessary to decide whether or 
not the CWA section 316(a) issue is not likely to be available in time 
for a decision on permit issuance, the Regional Administrator may issue 
a permit under Sec. 124.15 for a term up to 5 years. This permit shall 
require achievement of the effluent limitations initially proposed for 
the thermal component of the discharge no later than the date otherwise 
required by law. However, the permit shall also afford the permittee an 
opportunity to file a demonstration under CWA section 316(a) after 
conducting such studies as are required under 40 CFR part 125, subpart 
H. A new discharger may not exceed the thermal effluent limitation which 
is initially proposed unless and until its CWA section 316(a) variance 
request is finally approved.
    (c) Any proceeding held under paragraph (a) of this section shall be 
publicly noticed as required by Sec. 124.10 and shall be conducted at a 
time allowing the permittee to take necessary measures to meet the final 
compliance date in the event its request for modification of thermal 
limits is denied.
    (d) Whenever the Regional Administrator defers the decision under 
CWA section 316(a), any decision under section 316(b) may be deferred.

            Subpart G_Procedures for RCRA Standardized Permit

    Source: 70 FR 53449, Sept. 8, 2005, unless otherwise noted.

             General Information About Standardized Permits



Sec. 124.200  What is a RCRA standardized permit?

    The standardized permit is a special form of RCRA permit, that may 
consist of two parts: A uniform portion that the Director issues in all 
cases, and a supplemental portion that the Director issues at his or her 
discretion. We formally define the term ``Standardized permit'' in Sec. 
124.2.
    (a) What comprises the uniform portion? The uniform portion of a 
standardized permit consists of terms and conditions, relevant to the 
unit(s) you are operating at your facility, that EPA has promulgated in 
40 CFR part 267 (Standards for Owners and Operators of Hazardous Waste 
Facilities Operating under a Standardized Permit). If you intend to 
operate under the standardized permit, you must comply with these 
nationally applicable terms and conditions.
    (b) What comprises the supplemental portion? The supplemental 
portion of a standardized permit consists of site-specific terms and 
conditions, beyond those of the uniform portion, that the Director may 
impose on your particular facility, as necessary to protect human health 
and the environment. If the Director issues you a supplemental portion, 
you must comply with the site-specific terms and conditions it imposes.

[[Page 355]]

    (1) When required under Sec. 267.101, provisions to implement 
corrective action will be included in the supplemental portion.
    (2) Unless otherwise specified, these supplemental permit terms and 
conditions apply to your facility in addition to the terms and 
conditions of the uniform portion of the standardized permit and not in 
place of any of those terms and conditions.



Sec. 124.201  Who is eligible for a standardized permit?

    (a) You may be eligible for a standardized permit if:
    (1) You generate hazardous waste and then store or non-thermally 
treat the hazardous waste on-site in containers, tanks, or containment 
buildings; or
    (2) You receive hazardous waste generated off-site by a generator 
under the same ownership as the receiving facility, and then you store 
or non-thermally treat the hazardous waste in containers, tanks, or 
containment buildings.
    (3) In either case, the Director will inform you of your eligibility 
when a decision is made on your permit.
    (b) [Reserved]

                   Applying for a Standardized Permit



Sec. 124.202  How do I as a facility owner or operator apply for 
a standardized permit?

    (a) You must follow the requirements in this subpart as well as 
those in Sec. 124.31, 40 CFR 270.10, and 40 CFR part 270, subpart J.
    (b) You must submit to the Director a written Notice of Intent to 
operate under the standardized permit. You must also include the 
information and certifications required under 40 CFR part 270, subpart 
J.



Sec. 124.203  How may I switch from my individual RCRA permit to
a standardized permit?

    Where all units in the RCRA permit are eligible for the standardized 
permit, you may request that your individual permit be revoked and 
reissued as a standardized permit, in accordance with Sec. 124.5. Where 
only some of the units in the RCRA permit are eligible for the 
standardized permit, you may request that your individual permit be 
modified to no longer include those units and issue a standardized 
permit for those units in accordance with Sec. 124.204.

                      Issuing a Standardized Permit



Sec. 124.204  What must I do as the Director of the regulatory agency
to prepare a draft standardized permit?

    (a) You must review the Notice of Intent and supporting information 
submitted by the facility owner or operator.
    (b) You must determine whether the facility is or is not eligible to 
operate under the standardized permit.
    (1) If the facility is eligible for the standardized permit, you 
must propose terms and conditions, if any, to include in a supplemental 
portion. If you determine that these terms and conditions are necessary 
to protect human health and the environment and cannot be imposed, you 
must tentatively deny coverage under the standardized permit.
    (2) If the facility is not eligible for the standardized permit, you 
must tentatively deny coverage under the standardized permit. Cause for 
ineligibility may include, but is not limited to, the following:
    (i) Failure of owner or operator to submit all the information 
required under Sec. 270.275.
    (ii) Information submitted that is required under Sec. 270.275 is 
determined to be inadequate.
    (iii) Facility does not meet the eligibility requirements 
(activities are outside the scope of the standardized permit).
    (iv) Demonstrated history of significant non-compliance with 
applicable requirements.
    (v) Permit conditions cannot ensure protection of human health and 
the environment.
    (c) You must prepare your draft permit decision within 120 days 
after receiving the Notice of Intent and supporting documents from a 
facility owner or operator. Your tentative determination under this 
section to deny or grant coverage under the standardized permit, 
including any proposed site-specific conditions in a supplemental 
portion, constitutes a draft permit decision. You are allowed a one time 
extension of 30 days to prepare

[[Page 356]]

the draft permit decision. When the use of the 30-day extension is 
anticipated, you should inform the permit applicant during the initial 
120-day review period. Reasons for an extension may include, but is not 
limited to, needing to complete review of submissions with the Notice of 
Intent (e.g., closure plans, waste analysis plans, for facilities 
seeking to manage hazardous waste generated off-site).
    (d) Many requirements in subpart A of this part apply to processing 
the standardized permit application and preparing your draft permit 
decision. For example, your draft permit decision must be accompanied by 
a statement of basis or fact sheet and must be based on the 
administrative record. In preparing your draft permit decision, the 
following provisions of subpart A of this part apply (subject to the 
following modifications):
    (1) Section 124.1 Purpose and Scope. All paragraphs.
    (2) Section 124.2 Definitions. All paragraphs.
    (3) Section 124.3 Application for a permit. All paragraphs, except 
paragraphs (c), (d), (f), and (g) of this section apply.
    (4) Section 124.4 Consolidation of permit processing. All paragraphs 
apply; however, in the context of the RCRA standardized permit, the 
reference to the public comment period is Sec. 124.208 instead of Sec. 
124.10.
    (5) Section 124.5 Modification, revocation and re-issuance, or 
termination of permits. Not applicable.
    (6) Section 124.6 Draft permits. This section does not apply to the 
RCRA standardized permit; procedures in this subpart apply instead.
    (7) Section 124.7 Statement of basis. The entire section applies.
    (8) Section 124.8 Fact sheet. All paragraphs apply; however, in the 
context of the RCRA standardized permit, the reference to the public 
comment period is Sec. 124.208 instead of Sec. 124.10.
    (9) Section 124.9 Administrative record for draft permits when EPA 
is the permitting authority. All paragraphs apply; however, in the 
context of the RCRA standardized permit, the reference to draft permits 
is Sec. 24.204(c) instead of Sec. 124.6.
    (10) Section 124.10 Public notice of permit actions and public 
comment period. Only Sec. Sec. 124.10(c)(1)(ix) and (c)(1)(x)(A) apply 
to the RCRA standardized permit. Most of Sec. 124.10 does not apply to 
the RCRA standardized permit; Sec. Sec. 124.207, 124.208, and 124.209 
apply instead.



Sec. 124.205  What must I do as the Director of the regulatory agency
to prepare a final standardized permit?

    As Director of the regulatory agency, you must consider all comments 
received during the public comment period (see Sec. 124.208) in making 
your final permit decision. In addition, many requirements in subpart A 
of this part apply to the public comment period, public hearings, and 
preparation of your final permit decision. In preparing a final permit 
decision, the following provisions of subpart A of this part apply 
(subject to the following modifications):
    (a) Section 124.1 Purpose and Scope. All paragraphs.
    (b) Section 124.2 Definitions. All paragraphs.
    (c) Section 124.11 Public comments and requests for public hearings. 
This section does not apply to the RCRA standardized permit; the 
procedures in Sec. 124.208 apply instead.
    (d) Section 124.12 Public hearings. Paragraphs (b), (c), and (d) 
apply.
    (e) Section 124.13 Obligation to raise issues and provide 
information during the public comment period. The entire section 
applies; however, in the context of the RCRA standardized permit, the 
reference to the public comment period is Sec. 124.208 instead of Sec. 
124.10.
    (f) Section124.14 Reopening of the public comment period. All 
paragraphs apply; however, in the context of the RCRA standardized 
permit, use the following reference: in Sec. 124.14(b)(1) use reference 
to Sec. 124.204 instead of Sec. 124.6; in Sec. 124.14(b)(3) use 
reference to Sec. 124.208 instead of Sec. 124.10; in Sec. 124.14(c) 
use reference to Sec. 124.207 instead of Sec. 124.10.
    (g) Section 124.15 Issuance and effective date of permit. All 
paragraphs apply, however, in the context of the RCRA standardized 
permit, the reference to the public comment period is Sec. 124.208 
instead of Sec. 124.10.

[[Page 357]]

    (h) Section 124.16 Stays of contested permit conditions. All 
paragraphs apply.
    (i) Section 124.17 Response to comments. This section does not apply 
to the RCRA standardized permit; procedures in Sec. 124.209 apply 
instead.
    (j) Section 124.18 Administrative record for final permit when EPA 
is the permitting authority. All paragraphs apply, however, use 
reference to Sec. 124.209 instead of Sec. 124.17.
    (k) Seciton124.19 Appeal of RCRA, UIC, NPDES, and PSD permits. All 
paragraphs apply.
    (l) Section 124.20 Computation of time. All paragraphs apply.



Sec. 124.206  In what situations may I require a facility owner or
operator to apply for an individual permit?

    (a) Cases where you may determine that a facility is not eligible 
for the standardized permit include, but are not limited to, the 
following:
    (1) The facility does not meet the criteria in Sec. 124.201.
    (2) The facility has a demonstrated history of significant non-
compliance with regulations or permit conditions.
    (3) The facility has a demonstrated history of submitting incomplete 
or deficient permit application information.
    (4) The facility has submitted an incomplete or inadequate materials 
with the Notice of Intent.
    (b) If you determine that a facility is not eligible for the 
standardized permit, you must inform the facility owner or operator that 
they must apply for an individual permit.
    (c) You may require any facility that has a standardized permit to 
apply for and obtain an individual RCRA permit. Any interested person 
may petition you to take action under this paragraph. Cases where you 
may require an individual RCRA permit include, but are not limited to, 
the following:
    (1) The facility is not in compliance with the terms and conditions 
of the standardized RCRA permit.
    (2) Circumstances have changed since the time the facility owner or 
operator applied for the standardized permit, so that the facility's 
hazardous waste management practices are no longer appropriately 
controlled under the standardized permit.
    (d) You may require any facility authorized by a standardized permit 
to apply for an individual RCRA permit only if you have notified the 
facility owner or operator in writing that an individual permit 
application is required. You must include in this notice a brief 
statement of the reasons for your decision, a statement setting a 
deadline for the owner or operator to file the application, and a 
statement that, on the effective date of the individual RCRA permit, the 
facility's standardized permit automatically terminates. You may grant 
additional time upon request from the facility owner or operator.
    (e) When you issue an individual RCRA permit to an owner or operator 
otherwise subject to a standardized RCRA permit, the standardized permit 
for their facility will automatically cease to apply on the effective 
date of the individual permit.

 Opportunities for Public Involvement in the Standardized Permit Process



Sec. 124.207  What are the requirements for public notices?

    (a) You, as the Director, must provide public notice of your draft 
permit decision and must provide an opportunity for the public to submit 
comments and request a hearing on that decision. You must provide the 
public notice to:
    (1) The applicant;
    (2) Any other agency which you know has issued or is required to 
issue a RCRA permit for the same facility or activity (including EPA 
when the draft permit is prepared by the State);
    (3) Federal and State agencies with jurisdiction over fish, 
shellfish, and wildlife resources and over coastal zone management 
plans, the Advisory Council on Historic Preservation, State Historic 
Preservation Officers, including any affected States;
    (4) To everyone on the facility mailing list developed according to 
the requirements in Sec. 124.10(c)(1)(ix); and
    (5) To any units of local government having jurisdiction over the 
area where the facility is proposed to be located and to each State 
agency having any authority under State law with respect

[[Page 358]]

to the construction or operation of the facility.
    (b) You must issue the public notice according to the following 
methods:
    (1) Publication in a daily or weekly major local newspaper of 
general circulation and broadcast over local radio stations;
    (2) When the program is being administered by an approved State, in 
a manner constituting legal notice to the public under State law; and
    (3) Any other method reasonably calculated to give actual notice of 
the draft permit decision to the persons potentially affected by it, 
including press releases or any other forum or medium to elicit public 
participation.
    (c) You must include the following information in the public notice:
    (1) The name and telephone number of the contact person at the 
facility.
    (2) The name and telephone number of your contact office, and a 
mailing address to which people may direct comments, information, 
opinions, or inquiries.
    (3) An address to which people may write to be put on the facility 
mailing list.
    (4) The location where people may view and make copies of the draft 
standardized permit and the Notice of Intent and supporting documents.
    (5) A brief description of the facility and proposed operations, 
including the address or a map (for example, a sketched or copied street 
map) of the facility location on the front page of the notice.
    (6) The date that the facility owner or operator submitted the 
Notice of Intent and supporting documents.
    (d) At the same time that you issue the public notice under this 
section, you must place the draft standardized permit (including both 
the uniform portion and the supplemental portion, if any), the Notice of 
Intent and supporting documents, and the statement of basis or fact 
sheet in a location accessible to the public in the vicinity of the 
facility or at your office.



Sec. 124.208  What are the opportunities for public comments and 
hearings on draft permit decisions?

    (a) The public notice that you issue under Sec. 124.207 must allow 
at least 45 days for people to submit written comments on your draft 
permit decision. This time is referred to as the public comment period. 
You must automatically extend the public comment period to the close of 
any public hearing under this section. The hearing officer may also 
extend the comment period by so stating at the hearing.
    (b) During the public comment period, any interested person may 
submit written comments on the draft permit and may request a public 
hearing. If someone wants to request a public hearing, they must submit 
their request in writing to you. Their request must state the nature of 
the issues they propose to raise during the hearing.
    (c) You must hold a public hearing whenever you receive a written 
notice of opposition to a standardized permit and a request for a 
hearing within the public comment period under paragraph (a) of this 
section. You may also hold a public hearing at your discretion, 
whenever, for instance, such a hearing might clarify one or more issues 
involved in the permit decision.
    (d) Whenever possible, you must schedule a hearing under this 
section at a location convenient to the nearest population center to the 
facility. You must give public notice of the hearing at least 30 days 
before the date set for the hearing. (You may give the public notice of 
the hearing at the same time you provide public notice of the draft 
permit, and you may combine the two notices.)
    (e) You must give public notice of the hearing according to the 
methods in Sec. 124.207(a) and (b). The hearing must be conducted 
according to the procedures in Sec. 124.12(b), (c), and (d).
    (f) In their written comments and during the public hearing, if 
held, interested parties may provide comments on the draft permit 
decision. These comments may include, but are not limited to, the 
facility's eligibility for the standardized permit, the tentative 
supplemental conditions you proposed, and the need for additional 
supplemental conditions.

[[Page 359]]



Sec. 124.209  What are the requirements for responding to comments?

    (a) At the time you issue a final standardized permit, you must also 
respond to comments received during the public comment period on the 
draft permit. Your response must:
    (1) Specify which additional conditions (i.e., those in the 
supplemental portion), if any, you changed in the final permit, and the 
reasons for the change.
    (2) Briefly describe and respond to all significant comments on the 
facility's ability to meet the general requirements (i.e., those terms 
and conditions in the uniform portion) and on any additional conditions 
necessary to protect human health and the environment raised during the 
public comment period or during the hearing.
    (3) Make the comments and responses accessible to the public.
    (b) You may request additional information from the facility owner 
or operator or inspect the facility if you need additional information 
to adequately respond to significant comments or to make decisions about 
conditions you may need to add to the supplemental portion of the 
standardized permit.
    (c) If you are the Director of an EPA permitting agency, you must 
include in the administrative record for your final permit decision any 
documents cited in the response to comments. If new points are raised or 
new material supplied during the public comment period, you may document 
your response to those matters by adding new materials to the 
administrative record.



Sec. 124.210  May I, as an interested party in the permit process,
appeal a final standardized permit?

    You may petition for administrative review of the Director's final 
permit decision, including his or her decision that the facility is 
eligible for the standardized permit, according to the procedures of 
Sec. 124.19. However, the terms and conditions of the uniform portion 
of the standardized permit are not subject to administrative review 
under this provision.

                    Maintaining a Standardized Permit



Sec. 124.211  What types of changes may I make to my standardized
permit?

    You may make both routine changes, routine changes with prior Agency 
approval, and significant changes. For the purposes of this section:
    (a) ``Routine changes'' are any changes to the standardized permit 
that qualify as a class 1 permit modification (without prior Agency 
approval) under 40 CFR 270.42, appendix I, and
    (b) ``Routine changes with prior Agency approval'' are for those 
changes to the standardized permit that would qualify as a class 1 
modification with prior agency approval, or a class 2 permit 
modification under 40 CFR 270.42, appendix I; and
    (c) ``Significant changes'' are any changes to the standardized 
permit that:
    (1) Qualify as a class 3 permit modification under 40 CFR 270.42, 
appendix I;
    (2) Are not explicitly identified in 40 CFR 270.42, appendix I; or
    (3) Amend any terms or conditions in the supplemental portion of 
your standardized permit.



Sec. 124.212  What procedures must I follow to make routine changes?

    (a) You can make routine changes to the standardized permit without 
obtaining approval from the Director. However, you must first determine 
whether the routine change you will make amends the information you 
submitted under 40 CFR 270.275 with your Notice of Intent to operate 
under the standardized permit.
    (b) If the routine changes you make amend the information you 
submitted under 40 CFR 270.275 with your Notice of Intent to operate 
under the standardized permit, then before you make the routine changes 
you must:
    (1) Submit to the Director the revised information pursuant to 40 
CFR 270.275(a); and
    (2) Provide notice of the changes to the facility mailing list and 
to state and local governments in accordance with the procedures in 
Sec. 124.10(c)(1)(ix) and (x).

[[Page 360]]



Sec. 124.213  What procedures must I follow to make routine changes
with prior approval?

    (a) Routine changes to the standardized permit with prior Agency 
approval may only be made with the prior written approval of the 
Director.
    (b) You must also follow the procedures in Sec. 124.212(b)(1)-(2).



Sec. 124.214  What procedures must I follow to make significant changes?

    (a) You must first provide notice of and conduct a public meeting.
    (1) Public Meeting. You must hold a meeting with the public to 
solicit questions from the community and inform the community of your 
proposed modifications to your hazardous waste management activities. 
You must post a sign-in sheet or otherwise provide a voluntary 
opportunity for people attending the meeting to provide their names and 
addresses.
    (2) Public Notice. At least 30 days before you plan to hold the 
meeting, you must issue a public notice in accordance with the 
requirements of Sec. 124.31(d).
    (b) After holding the public meeting, you must submit a modification 
request to the Director that:
    (1) Describes the exact change(s) you want and whether they are 
changes to information you provided under 40 CFR 270.275 or to terms and 
conditions in the supplemental portion of your standardized permit;
    (2) Explain why the modification is needed; and
    (3) Includes a summary of the public meeting under paragraph (a) of 
this section, along with the list of attendees and their addresses and 
copies of any written comments or materials they submitted at the 
meeting.
    (c) Once the Director receives your modification request, he or she 
must make a tentative determination within 120 days to approve or 
disapprove your request. You are allowed a one time extension of 30 days 
to prepare the draft permit decision. When the use of the 30-day 
extension is anticipated, you should inform the permit applicant during 
the initial 120-day review period.
    (d) After the Director makes this tentative determination, the 
procedures in Sec. 124.205 and Sec. Sec. 124.207 through 124.210 for 
processing an initial request for coverage under the standardized permit 
apply to making the final determination on the modification request.

Subpart A_Criteria and Standards for Imposing Technology-Based Treatment 
          Requirements Under Sections 301(b) and 402 of the Act



Sec. 125.1  Purpose and scope.

    This subpart establishes criteria and standards for the imposition 
of technology-based treatment requirements in permits under section 
301(b) of the Act, including the application of EPA promulgated effluent 
limitations and case-by-case determinations of effluent limitations 
under section 402(a)(1) of the Act.



Sec. 125.2  Definitions.

    For the purposes of this part, any reference to the Act shall mean 
the Clean Water Act of 1977 (CWA). Unless otherwise noted, the 
definitions in parts 122, 123 and 124 apply to this part.

[45 FR 33512, May 19, 1980]



Sec. 125.3  Technology-based treatment requirements in permits.

    (a) General. Technology-based treatment requirements under section 
301(b) of the Act represent the minimum level of control that must be 
imposed in a permit issued under section 402 of the Act. (See Sec. Sec. 
122.41, 122.42 and 122.44 for a discussion of additional or more 
stringent effluent limitations and conditions.) Permits shall contain 
the following technology-based treatment requirements in accordance with 
the following statutory deadlines;
    (1) For POTW's, effluent limitations based upon:
    (i) Secondary treatment--from date of permit issuance; and
    (ii) The best practicable waste treatment technology--not later than 
July 1, 1983; and
    (2) For dischargers other than POTWs except as provided in Sec. 
122.29(d), effluent limitations requiring:
    (i) The best practicable control technology currently available 
(BPT)--
    (A) For effluent limitations promulgated under Section 304(b) after 
January 1, 1982 and requiring a level of control substantially greater 
or based on fundamentally different control technology than under 
permits for an industrial category issued before such date, compliance 
as expeditiously as practicable but in no case later than three years 
after the date such limitations are promulgated under section 304(b) and 
in no case later than March 31, 1989;
    (B) For effluent limitations established on a case-by-case basis 
based on Best Professional Judgment (BPJ) under Section 402(a)(1)(B) of 
the Act in a permit issued after February 4, 1987, compliance as 
expeditiously as practicable but in no case later than three years after 
the date such limitations are established and in no case later than 
March 31, 1989;
    (C) For all other BPT effluent limitations compliance is required 
from the date of permit issuance.
    (ii) For conventional pollutants, the best conventional pollutant 
control technology (BCT)--
    (A) For effluent limitations promulgated under section 304(b), as 
expeditiously as practicable but in no case later than three years after 
the date such limitations are promulgated under section 304(b), and in 
no case later than March 31, 1989.
    (B) For effluent limitations established on a case-by-case (BPJ) 
basis under section 402(a)(1)(B) of the Act in a permit issued after 
February 4, 1987, compliance as expeditiously as practicable but in no 
case later than three years after the date such limitations are 
established and in no case later than March 31, 1989;
    (iii) For all toxic pollutants referred to in Committee Print No. 
95-30, House Committee on Public Works and Transportation, the best 
available technology economically achievable (BAT)--
    (A) For effluent limitations established under section 304(b), as 
expeditiously as practicable but in no case

[[Page 363]]

later than three years after the date such limitations are promulgated 
under section 304(b), and in no case later than March 31, 1989.
    (B) For permits issued on a case-by-case (BPJ) basis under section 
402(a)(1)(B) of the Act after February 4, 1987 establishing BAT effluent 
limitations, compliance is required as expeditiously as practicable but 
in no case later than three years after the date such limitations are 
promulgated under section 304(b), and in no case later than March 31, 
1989.
    (iv) For all toxic pollutants other than those listed in Committee 
Print No. 95-30, effluent limitations based on BAT--
    (A) For effluent limitations promulgated under section 304(b) 
compliance is required as expeditiously as practicable, but in no case 
later than three years after the date such limitations are promulgated 
under section 304(b) and in no case later than March 31, 1989.
    (B) For permits issued on a case-by-case (BPJ) basis under Section 
402(a)(1)(B) of the Act after February 4, 1987 establishing BAT effluent 
limitations, compliance is required as expeditiously as practicable but 
in no case later than 3 years after the date such limitations are 
established and in no case later than March 31, 1989.
    (v) For all pollutants which are neither toxic nor conventional 
pollutants, effluent limitations based on BAT--
    (A) For effluent limitations promulgated under section 304(b), 
compliance is required as expeditiously as practicable but in no case 
later than 3 years after the date such limitations are established and 
in no case later than March 31, 1989.
    (B) For permits issued on a case-by-case (BPJ) basis under section 
402(a)(1)(B) of the Act after February 4, 1987 establishing BAT effluent 
limitations compliance is required as expeditiously as practicable but 
in no case later than three years after the date such limitations are 
established and in no case later than March 31, 1989.
    (b) Statutory variances and extensions. (1) The following variances 
from technology-based treatment requirements are authorized by the Act 
and may be applied for under Sec. 122.21;
    (i) For POTW's, a section 301(h) marine discharge variance from 
secondary treatment (subpart G);
    (ii) For dischargers other than POTW's;
    (A) A section 301(c) economic variance from BAT (subpart E);
    (B) A section 301(g) water quality related variance from BAT 
(subpart F); and
    (C) A section 316(a) thermal variance from BPT, BCT and BAT (subpart 
H).
    (2) The following extensions of deadlines for compliance with 
technology-based treatment requirements are authorized by the Act and 
may be applied for under Sec. 124.53:
    (i) For POTW's a section 301(i) extension of the secondary treatment 
deadline (subpart J);
    (ii) For dischargers other than POTW's:
    (A) A section 301(i) extension of the BPT deadline (subpart J); and
    (B) A section 301(k) extension of the BAT deadline (subpart C).
    (c) Methods of imposing technology-based treatment requirements in 
permits. Technology-based treatment requirements may be imposed through 
one of the following three methods:
    (1) Application of EPA-promulgated effluent limitations developed 
under section 304 of the Act to dischargers by category or subcategory. 
These effluent limitations are not applicable to the extent that they 
have been remanded or withdrawn. However, in the case of a court remand, 
determinations underlying effluent limitations shall be binding in 
permit issuance proceedings where those determinations are not required 
to be reexamined by a court remanding the regulations. In addition, 
dischargers may seek fundamentally different factors variances from 
these effluent limitations under Sec. 122.21 and subpart D of this 
part.
    (2) On a case-by-case basis under section 402(a)(1) of the Act, to 
the extent that EPA-promulgated effluent limitations are inapplicable. 
The permit writer shall apply the appropriate factors listed in Sec. 
125.3(d) and shall consider:
    (i) The appropriate technology for the category or class of point 
sources of which the applicant is a member,

[[Page 364]]

based upon all available information; and
    (ii) Any unique factors relating to the applicant.

[Comment: These factors must be considered in all cases, regardless of 
whether the permit is being issued by EPA or an approved State.]

    (3) Through a combination of the methods in paragraphs (d) (1) and 
(2) of this section. Where promulgated effluent limitations guidelines 
only apply to certain aspects of the discharger's operation, or to 
certain pollutants, other aspects or activities are subject to 
regulation on a case-by-case basis in order to carry out the provisions 
of the Act.
    (4) Limitations developed under paragraph (d)(2) of this section may 
be expressed, where appropriate, in terms of toxicity (e.g., ``the 
LC50 for fat head minnow of the effluent from outfall 001 
shall be greater than 25%''). Provided, That is shown that the limits 
reflect the appropriate requirements (for example, technology-based or 
water-quality-based standards) of the Act.
    (d) In setting case-by-case limitations pursuant to Sec. 125.3(c), 
the permit writer must consider the following factors:
    (1) For BPT requirements: (i) The total cost of application of 
technology in relation to the effluent reduction benefits to be achieved 
from such application;
    (ii) The age of equipment and facilities involved;
    (iii) The process employed;
    (iv) The engineering aspects of the application of various types of 
control techniques;
    (v) Process changes; and
    (vi) Non-water quality environmental impact (including energy 
requirements).
    (2) For BCT requirements: (i) The reasonableness of the relationship 
between the costs of attaining a reduction in effluent and the effluent 
reduction benefits derived;
    (ii) The comparison of the cost and level of reduction of such 
pollutants from the discharge from publicly owned treatment works to the 
cost and level of reduction of such pollutants from a class or category 
of industrial sources;
    (iii) The age of equipment and facilities involved;
    (iv) The process employed;
    (v) The engineering aspects of the application of various types of 
control techniques;
    (vi) Process changes; and
    (vii) Non-water quality environmental impact (including energy 
requirements).
    (3) For BAT requirements: (i) The age of equipment and facilities 
involved;
    (ii) The process employed;
    (iii) The engineering aspects of the application of various types of 
control techniques;
    (iv) Process changes;
    (v) The cost of achieving such effluent reduction; and
    (vi) Non-water quality environmental impact (including energy 
requirements).
    (e) Technology-based treatment requirements are applied prior to or 
at the point of discharge.
    (f) Technology-based treatment requirements cannot be satisfied 
through the use of ``non-treatment'' techniques such as flow 
augmentation and in-stream mechanical aerators. However, these 
techniques may be considered as a method of achieving water quality 
standards on a case-by-case basis when:
    (1) The technology-based treatment requirements applicable to the 
discharge are not sufficient to achieve the standards;
    (2) The discharger agrees to waive any opportunity to request a 
variance under section 301 (c), (g) or (h) of the Act; and
    (3) The discharger demonstrates that such a technique is the 
preferred environmental and economic method to achieve the standards 
after consideration of alternatives such as advanced waste treatment, 
recycle and reuse, land disposal, changes in operating methods, and 
other available methods.
    (g) Technology-based effluent limitations shall be established under 
this subpart for solids, sludges, filter backwash, and other pollutants 
removed in the course of treatment or control of wastewaters in the same 
manner as for other pollutants.
    (h)(1) The Director may set a permit limit for a conventional 
pollutant at a

[[Page 365]]

level more stringent than the best conventional pollution control 
technology (BCT), or a limit for a nonconventional pollutant which shall 
not be subject to modification under section 301 (c) or (g) of the Act 
where:
    (i) Effluent limitations guidelines specify the pollutant as an 
indicator for a toxic pollutant, or
    (ii)(A) The limitation reflects BAT-level control of discharges of 
one or more toxic pollutants which are present in the waste stream, and 
a specific BAT limitation upon the toxic pollutant(s) is not feasible 
for economic or technical reasons;
    (B) The permit identifies which toxic pollutants are intended to be 
controlled by use of the limitation; and
    (C) The fact sheet required by Sec. 124.56 sets forth the basis for 
the limitation, including a finding that compliance with the limitation 
will result in BAT-level control of the toxic pollutant discharges 
identified in paragraph (h)(1)(ii)(B) of this section, and a finding 
that it would be economically or technically infeasible to directly 
limit the toxic pollutant(s).
    (2) The Director may set a permit limit for a conventional pollutant 
at a level more stringent than BCT when:
    (i) Effluent limitations guidelines specify the pollutant as an 
indicator for a hazardous substance, or
    (ii)(A) The limitation reflects BAT-level control of discharges (or 
an appropriate level determined under section 301(c) or (g) of the Act) 
of one or more hazardous substance(s) which are present in the waste 
stream, and a specific BAT (or other appropriate) limitation upon the 
hazardous substance(s) is not feasible for economic or technical 
reasons;
    (B) The permit identifies which hazardous substances are intended to 
be controlled by use of the limitation; and
    (C) The fact sheet required by Sec. 124.56 sets forth the basis for 
the limitation, including a finding that compliance with the limitations 
will result in BAT-level (or other appropriate level) control of the 
hazardous substances discharges identified in paragraph (h)(2)(ii)(B) of 
this section, and a finding that it would be economically or technically 
infeasible to directly limit the hazardous substance(s).
    (iii) Hazardous substances which are also toxic pollutants are 
subject to paragraph (h)(1) of this section.
    (3) The Director may not set a more stringent limit under the 
preceding paragraphs if the method of treatment required to comply with 
the limit differs from that which would be required if the toxic 
pollutant(s) or hazardous substance(s) controlled by the limit were 
limited directly.
    (4) Toxic pollutants identified under paragraph (h)(1) of this 
section remain subject to the requirements of Sec. 122.42(a)(1) 
(notification of increased discharges of toxic pollutants above levels 
reported in the application form).

   Subpart B_Criteria for Issuance of Permits to Aquaculture Projects



Sec. 125.10  Purpose and scope.

    (a) These regulations establish guidelines under sections 318 and 
402 of the Act for approval of any discharge of pollutants associated 
with an aquaculture project.
    (b) The regulations authorize, on a selective basis, controlled 
discharges which would otherwise be unlawful under the Act in order to 
determine the feasibility of using pollutants to grow aquatic organisms 
which can be harvested and used beneficially. EPA policy is to encourage 
such projects, while at the same time protecting other beneficial uses 
of the waters.
    (c) Permits issued for discharges into aquaculture projects under 
this subpart are NPDES permits and are subject to the applicable 
requirements of parts 122, 123 and 124. Any permit shall include such 
conditions (including monitoring and reporting requirements) as are 
necessary to comply with those parts. Technology-based effluent 
limitations need not be applied to discharges into the approved project 
except with respect to toxic pollutants.

[[Page 366]]



Sec. 125.11  Criteria.

    (a) No NPDES permit shall be issued to an aquaculture project 
unless:
    (1) The Director determines that the aquaculture project:
    (i) Is intended by the project operator to produce a crop which has 
significant direct or indirect commercial value (or is intended to be 
operated for research into possible production of such a crop); and
    (ii) Does not occupy a designated project area which is larger than 
can be economically operated for the crop under cultivation or than is 
necessary for research purposes.
    (2) The applicant has demonstrated, to the satisfaction of the 
Director, that the use of the pollutant to be discharged to the 
aquaculture project will result in an increased harvest of organisms 
under culture over what would naturally occur in the area;
    (3) The applicant has demonstrated, to the satisfaction of the 
Director, that if the species to be cultivated in the aquaculture 
project is not indigenous to the immediate geographical area, there will 
be minimal adverse effects on the flora and fauna indigenous to the 
area, and the total commercial value of the introduced species is at 
least equal to that of the displaced or affected indigenous flora and 
fauna;
    (4) The Director determines that the crop will not have a 
significant potential for human health hazards resulting from its 
consumption;
    (5) The Director determines that migration of pollutants from the 
designated project area to water outside of the aquaculture project will 
not cause or contribute to a violation of water quality standards or a 
violation of the applicable standards and limitations applicable to the 
supplier of the pollutant that would govern if the aquaculture project 
were itself a point source. The approval of an aquaculture project shall 
not result in the enlargement of a pre-existing mixing zone area beyond 
what had been designated by the State for the original discharge.
    (b) No permit shall be issued for any aquaculture project in 
conflict with a plan or an amendment to a plan approved under section 
208(b) of the Act.
    (c) No permit shall be issued for any aquaculture project located in 
the territorial sea, the waters of the contiguous zone, or the oceans, 
except in conformity with guidelines issued under section 403(c) of the 
Act.
    (d) Designated project areas shall not include a portion of a body 
of water large enough to expose a substantial portion of the indigenous 
biota to the conditions within the designated project area. For example, 
the designated project area shall not include the entire width of a 
watercourse, since all organisms indigenous to that watercourse might be 
subjected to discharges of pollutants that would, except for the 
provisions of section 318 of the Act, violate section 301 of the Act.
    (e) Any modifications caused by the construction or creation of a 
reef, barrier or containment structure shall not unduly alter the tidal 
regimen of an estuary or interfere with migrations of unconfined aquatic 
species.

[Comment: Any modifications described in this paragraph which result in 
the discharge of dredged or fill material into navigable waters may be 
subject to the permit requirements of section 404 of the Act.]

    (f) Any pollutants not required by or beneficial to the aquaculture 
crop shall not exceed applicable standards and limitations when entering 
the designated project area.

Subpart C [Reserved]



Subpart D_Criteria and Standards for Determining Fundamentally Different 
  Factors Under Sections 301(b)(1)(A), 301(b)(2) (A) and (E) of the Act



Sec. 125.30  Purpose and scope.

    (a) This subpart establishes the criteria and standards to be used 
in determining whether effluent limitations alternative to those 
required by promulgated EPA effluent limitations guidelines under 
sections 301 and 304 of the Act (hereinafter referred to as ``national 
limits'') should be imposed on a discharger because factors relating to 
the discharger's facilities, equipment, processes or other factors 
related to the discharger are fundamentally different from the factors 
considered by EPA in development of the national

[[Page 367]]

limits. This subpart applies to all national limitations promulgated 
under sections 301 and 304 of the Act, except for the BPT limits 
contained in 40 CFR 423.12 (steam electric generating point source 
category).
    (b) In establishing national limits, EPA takes into account all the 
information it can collect, develop and solicit regarding the factors 
listed in sections 304(b) and 304(g) of the Act. In some cases, however, 
data which could affect these national limits as they apply to a 
particular discharge may not be available or may not be considered 
during their development. As a result, it may be necessary on a case-by-
case basis to adjust the national limits, and make them either more or 
less stringent as they apply to certain dischargers within an industrial 
category or subcategory. This will only be done if data specific to that 
discharger indicates it presents factors fundamentally different from 
those considered by EPA in developing the limit at issue. Any interested 
person believing that factors relating to a discharger's facilities, 
equipment, processes or other facilities related to the discharger are 
fundamentally different from the factors considered during development 
of the national limits may request a fundamentally different factors 
variance under Sec. 122.21(l)(1). In addition, such a variance may be 
proposed by the Director in the draft permit.

1983]



Sec. 125.31  Criteria.

    (a) A request for the establishment of effluent limitations under 
this subpart (fundamentally different factors variance) shall be 
approved only if:
    (1) There is an applicable national limit which is applied in the 
permit and specifically controls the pollutant for which alternative 
effluent limitations or standards have been requested; and
    (2) Factors relating to the discharge controlled by the permit are 
fundamentally different from those considered by EPA in establishing the 
national limits; and
    (3) The request for alternative effluent limitations or standards is 
made in accordance with the procedural requirements of part 124.
    (b) A request for the establishment of effluent limitations less 
stringent than those required by national limits guidelines shall be 
approved only if:
    (1) The alternative effluent limitation or standard requested is no 
less stringent than justified by the fundamental difference; and
    (2) The alternative effluent limitation or standard will ensure 
compliance with sections 208(e) and 301(b)(1)(C) of the Act; and
    (3) Compliance with the national limits (either by using the 
technologies upon which the national limits are based or by other 
control alternatives) would result in:
    (i) A removal cost wholly out of proportion to the removal cost 
considered during development of the national limits; or
    (ii) A non-water quality environmental impact (including energy 
requirements) fundamentally more adverse than the impact considered 
during development of the national limits.
    (c) A request for alternative limits more stringent than required by 
national limits shall be approved only if:
    (1) The alternative effluent limitation or standard requested is no 
more stringent than justified by the fundamental difference; and
    (2) Compliance with the alternative effluent limitation or standard 
would not result in:
    (i) A removal cost wholly out of proportion to the removal cost 
considered during development of the national limits; or
    (ii) A non-water quality environmental impact (including energy 
requirements) fundamentally more adverse than the impact considered 
during development of the national limits.
    (d) Factors which may be considered fundamentally different are:

[[Page 368]]

    (1) The nature or quality of pollutants contained in the raw waste 
load of the applicant's process wastewater;

[Comment: (1) In determining whether factors concerning the discharger 
are fundamentally different, EPA will consider, where relevant, the 
applicable development document for the national limits, associated 
technical and economic data collected for use in developing each 
respective national limit, records of legal proceedings, and written and 
printed documentation including records of communication, etc., relevant 
to the development of respective national limits which are kept on 
public file by EPA.
    (2) Waste stream(s) associated with a discharger's process 
wastewater which were not considered in the development of the national 
limits will not ordinarily be treated as fundamentally different under 
paragraph (a) of this section. Instead, national limits should be 
applied to the other streams, and the unique stream(s) should be subject 
to limitations based on section 402(a)(1) of the Act. See Sec. 
125.2(c)(2).]

    (2) The volume of the discharger's process wastewater and effluent 
discharged;
    (3) Non-water quality environmental impact of control and treatment 
of the discharger's raw waste load;
    (4) Energy requirements of the application of control and treatment 
technology;
    (5) Age, size, land availability, and configuration as they relate 
to the discharger's equipment or facilities; processes employed; process 
changes; and engineering aspects of the application of control 
technology;
    (6) Cost of compliance with required control technololgy.
    (e) A variance request or portion of such a request under this 
section shall not be granted on any of the following grounds:
    (1) The infeasibility of installing the required waste treatment 
equipment within the time the Act allows.

[Comment: Under this section a variance request may be approved if it is 
based on factors which relate to the discharger's ability ultimately to 
achieve national limits but not if it is based on factors which merely 
affect the discharger's ability to meet the statutory deadlines of 
sections 301 and 307 of the Act such as labor difficulties, construction 
schedules, or unavailability of equipment.]

    (2) The assertion that the national limits cannot be achieved with 
the appropriate waste treatment facilities installed, if such assertion 
is not based on factor(s) listed in paragraph (d) of this section;

[Comment: Review of the Administrator's action in promulgating national 
limits is available only through the judicial review procedures set 
forth in section 509(b) of the Act.]

    (3) The discharger's ability to pay for the required waste 
treatment; or
    (4) The impact of a discharge on local receiving water quality.
    (f) Nothing in this section shall be construed to impair the right 
of any State or locality under section 510 of the Act to impose more 
stringent limitations than those required by Federal law.



Sec. 125.32  Method of application.

    (a) A written request for a variance under this subpart D shall be 
submitted in duplicate to the Director in accordance with Sec. Sec. 
122.21(m)(1) and 124.3 of this chapter.
    (b) The burden is on the person requesting the variance to explain 
that:
    (1) Factor(s) listed in Sec. 125.31(b) regarding the discharger's 
facility are fundamentally different from the factors EPA considered in 
establishing the national limits. The requester should refer to all 
relevant material and information, such as the published guideline 
regulations development document, all associated technical and economic 
data collected for use in developing each national limit, all records of 
legal proceedings, and all written and printed documentation including 
records of communication, etc., relevant to the regulations which are 
kept on public file by the EPA;
    (2) The alternative limitations requested are justified by the 
fundamental difference alleged in paragraph (b)(1) of this section; and
    (3) The appropriate requirements of Sec. 125.31 have been met.

 Subpart G_Criteria for Modifying the Secondary Treatment Requirements 
               Under Section 301(h) of the Clean Water Act

    Authority: Clean Water Act, as amended by the Clean Water Act of 
1977, 33 U.S.C. 1251 et seq., unless otherwise noted.

    Source: 59 FR 40658, Aug. 9, 1994, unless otherwise noted.



Sec. 125.56  Scope and purpose.

    This subpart establishes the criteria to be applied by EPA in acting 
on section 301(h) requests for modifications to the secondary treatment 
requirements. It also establishes special permit conditions which must 
be included in any permit incorporating a section 301(h) modification of 
the secondary treatment requirements (``section 301(h) modified 
permit'').



Sec. 125.57  Law governing issuance of a section 301(h) modified permit.

    (a) Section 301(h) of the Clean Water Act provides that:

    Administrator, with the concurrence of the State, may issue a permit 
under section 402 which modifies the requirements of paragraph (b)(1)(B) 
of this section with respect to the discharge of any pollutant from a 
publicly owned treatment works into marine waters, if the applicant 
demonstrates to the satisfaction of the Administrator that--
    (1) There is an applicable water quality standard specific to the 
pollutant for which the modification is requested, which has been 
identified under section 304(a)(6) of this Act;
    (2) The discharge of pollutants in accordance with such modified 
requirements will not interfere, alone or in combination with pollutants 
from other sources, with the attainment or maintenance of that water 
quality which assures protection of public water supplies and protection 
and propagation of a balanced indigenous population of shellfish, fish, 
and wildlife, and allows recreational activities, in and on the water;
    (3) The applicant has established a system for monitoring the impact 
of such discharge on a representative sample of aquatic biota, to the 
extent practicable, and the scope of such monitoring is limited to 
include only those scientific investigations which are necessary to 
study the effects of the proposed discharge;
    (4) Such modified requirements will not result in any additional 
requirements on any other point or nonpoint source;
    (5) All applicable pretreatment requirements for sources introducing 
waste into such treatment works will be enforced;
    (6) In the case of any treatment works serving a population of 
50,000 or more, with respect to any toxic pollutant introduced into such 
works by an industrial discharger for which pollutant there is no 
applicable pretreatment requirement in effect, sources introducing waste 
into such works are in compliance with all applicable pretreatment 
requirements, the applicant will enforce such requirements, and the 
applicant has in effect a pretreatment program which, in combination 
with the treatment of discharges from such works, removes the same 
amount of such pollutant as would be removed if such works were to apply 
secondary treatment to discharges and if such works had no pretreatment 
program with respect to such pollutant;
    (7) To the extent practicable, the applicant has established a 
schedule of activities designed to eliminate the entrance of toxic 
pollutants from nonindustrial sources into such treatment works;
    (8) There will be no new or substantially increased discharges from 
the point source of the pollutant to which the modification applies 
above that volume of discharge specified in the permit;
    (9) The applicant at the time such modification becomes effective 
will be discharging effluent which has received at least primary or 
equivalent treatment and which meets the criteria established under 
section 304(a)(1) of this Act after initial mixing in the waters 
surrounding or adjacent to the point at which such effluent is 
discharged.
    For the purposes of this section, the phrase ``the discharge of any 
pollutant into marine waters'' refers to a discharge into deep waters of 
the territorial sea or the waters of the contiguous zone, or into saline 
estuarine waters where there is strong tidal movement and other 
hydrological and geological characteristics which the Administrator 
determines necessary to allow compliance with paragraph (2) of this 
section, and section 101(a)(2) of this Act. For the purposes of 
paragraph (9), ``primary or equivalent treatment'' means treatment by 
screening, sedimentation, and skimming adequate to remove at least 30 
percent of the biological oxygen demanding material and of the suspended 
solids in the treatment works influent, and disinfection, where 
appropriate. A municipality which applies secondary treatment shall be 
eligible to receive a permit pursuant to this subsection which modifies

[[Page 370]]

the requirements of paragraph (b)(1)(B) of this section with respect to 
the discharge of any pollutant from any treatment works owned by such 
municipality into marine waters. No permit issued under this subsection 
shall authorize the discharge of sewage sludge into marine waters. In 
order for a permit to be issued under this subsection for the discharge 
of a pollutant into marine waters, such marine waters must exhibit 
characteristics assuring that water providing dilution does not contain 
significant amounts of previously discharged effluent from such 
treatment works. No permit issued under this subsection shall authorize 
the discharge of any pollutant into saline estuarine waters which at the 
time of application do not support a balanced indigenous population of 
shellfish, fish, and wildlife, or allow recreation in and on the waters 
or which exhibit ambient water quality below applicable water quality 
standards adopted for the protection of public water supplies, 
shellfish, fish, and wildlife or recreational activities or such other 
standards necessary to assure support and protection of such uses. The 
prohibition contained in the preceding sentence shall apply without 
regard to the presence or absence of a causal relationship between such 
characteristics and the applicant's current or proposed discharge. 
Notwithstanding any other provisions of this subsection, no permit may 
be issued under this subsection for discharge of a pollutant into the 
New York Bight Apex consisting of the ocean waters of the Atlantic Ocean 
westward of 73 degrees 30 minutes west longitude and northward of 40 
degrees 10 minutes north latitude.

    (b) Section 301(j)(1) of the Clean Water Act provides that:

    Any application filed under this section for a modification of the 
provisions of--
    (A) subsection (b)(1)(B) under subsection (h) of this section shall 
be filed not later than the 365th day which begins after the date of 
enactment of the Municipal Wastewater Treatment Construction Grant 
Amendments of 1981, except that a publicly owned treatment works which 
prior to December 31, 1982, had a contractual arrangement to use a 
portion of the capacity of an ocean outfall operated by another publicly 
owned treatment works which has applied for or received modification 
under subsection (h) may apply for a modification of subsection (h) in 
its own right not later than 30 days after the date of the enactment of 
the Water Quality Act of 1987.

    (c) Section 22(e) of the Municipal Wastewater Treatment Construction 
Grant Amendments of 1981, Public Law 97-117, provides that:

    The amendments made by this section shall take effect on the date of 
enactment of this Act except that no applicant, other than the city of 
Avalon, California, who applies after the date of enactment of this Act 
for a permit pursuant to subsection (h) of section 301 of the Federal 
Water Pollution Control Act which modifies the requirements of 
subsection (b)(1)(B) of section 301 of such Act shall receive such 
permit during the one-year period which begins on the date of enactment 
of this Act.

    (d) Section 303(b)(2) of the Water Quality Act, Public Law 100-4, 
provides that:

    Section 301(h)(3) shall only apply to modifications and renewals of 
modifications which are tentatively or finally approved after the date 
of the enactment of this Act.

    (e) Section 303(g) of the Water Quality Act provides that:

    The amendments made to sections 301(h) and (h)(2), as well as 
provisions of (h)(6) and (h)(9), shall not apply to an application for a 
permit under section 301(h) of the Federal Water Pollution Control Act 
which has been tentatively or finally approved by the Administrator 
before the date of the enactment of this Act; except that such 
amendments shall apply to all renewals of such permits after such date 
of enactment.

    (4) State determination deadline. State determinations, as required 
by Sec. Sec. 125.61(b)(2) and 125.64(b) shall be filed by the applicant 
with the appropriate Regional Administrator no later than 90 days after 
submission of the revision to the application or additional information 
to EPA. Extensions to this deadline may be provided by EPA upon request. 
However, EPA will not begin review of the revision to the application or 
additional information until a favorable State determination is received 
by EPA. Failure to provide the State determination within the timeframe 
required by this paragraph (f)(4) is a basis for denial of the 
application.

[[Page 375]]

    (g)(1) The Administrator may authorize or request an applicant to 
submit additional information by a specified date not to exceed one year 
from the date of authorization or request.
    (2) Applicants seeking authorization to submit additional 
information on current/modified discharge characteristics, water 
quality, biological conditions or oceanographic characteristics must:
    (i) Demonstrate that they made a diligent effort to provide such 
information with their application and were unable to do so, and
    (ii) Submit a plan of study, including a schedule, for data 
collection and submittal of the additional information. EPA will review 
the plan of study and may require revisions prior to authorizing 
submission of the additional information.
    (h) Tentative decisions on section 301(h) modifications. The 
Administrator shall grant a tentative approval or a tentative denial of 
a section 301(h) modified permit application. To qualify for a tentative 
approval, the applicant shall demonstrate to the satisfaction of the 
Administrator that it is using good faith means to come into compliance 
with all the requirements of this subpart and that it will meet all such 
requirements based on a schedule approved by the Administrator. For 
compliance with Sec. Sec. 125.60 and 125.65, such schedule shall be in 
accordance with Sec. 125.59(f)(3)(ii).
    (i) Decisions on section 301(h) modifications. (1) The decision to 
grant or deny a section 301(h) modification shall be made by the 
Administrator and shall be based on the applicant's demonstration that 
it has met all the requirements of Sec. Sec. 125.59 through 125.68.
    (2) No section 301(h) modified permit shall be issued until the 
appropriate State certification/concurrence is granted or waived 
pursuant to Sec. 124.54 or if the State denies certification/ 
concurrence pursuant to Sec. 124.54.
    (3) In the case of a modification issued to an applicant in a State 
administering an approved permit program under 40 CFR part 123, the 
State Director may:
    (i) Revoke an existing permit as of the effective date of the EPA 
issued section 301(h) modified permit; and
    (ii) Cosign the section 301(h) modified permit if the Director has 
indicated an intent to do so in the written concurrence.
    (4) Any section 301(h) modified permit shall:
    (i) Be issued in accordance with the procedures set forth in 40 CFR 
part 124, except that, because section 301(h) permits may be issued only 
by EPA, the terms ``Administrator or a person designated by the 
Administrator'' shall be substituted for the term ``Director'' as 
appropriate; and
    (ii) Contain all applicable terms and conditions set forth in 40 CFR 
part 122 and Sec. 125.68.
    (5) Appeals of section 301(h) determinations shall be governed by 
the procedures in 40 CFR part 124.
    (j) Grandfathering provision. Applicants that received tentative or 
final approval for a section 301(h) modified permit prior to February 4, 
1987, are not subject to Sec. 125.60, the water quality criteria 
provisions of Sec. 125.62(a)(1), or Sec. 125.65 until the time of 
permit renewal. In addition, if permit renewal will occur prior to 
August 9, 1996, applicants may have additional time to come into 
compliance with Sec. Sec. 125.60 and 125.65, as determined appropriate 
by EPA on a case-by-case basis. Such additional time, however, shall not 
extend beyond August 9, 1996. This paragraph does not apply to any 
application that was initially tentatively approved, but as to which EPA 
withdrew its tentative approval or issued a tentative denial prior to 
February 4, 1987.



Sec. 125.60  Primary or equivalent treatment requirements.

    (a) The applicant shall demonstrate that, at the time its 
modification becomes effective, it will be discharging effluent that has 
received at least primary or equivalent treatment.
    (b) The applicant shall perform monitoring to ensure, based on the 
monthly average results of the monitoring, that the effluent it 
discharges has received primary or equivalent treatment.
    (c)(1) An applicant may request that the demonstration of compliance 
with the requirement under paragraph (b) of this section to provide 30 
percent removal of BOD be allowed on an averaging basis different from 
monthly

[[Page 376]]

(e.g., quarterly), subject to the demonstrations provided in paragraphs 
(c)(1)(i), (ii) and (iii) of this section. The Administrator may approve 
such requests if the applicant demonstrates to the Administrator's 
satisfaction that:
    (i) The applicant's POTW is adequately designed and well operated;
    (ii) The applicant will be able to meet all requirements under 
section 301(h) of the CWA and these subpart G regulations with the 
averaging basis selected; and
    (iii) The applicant cannot achieve 30 percent removal on a monthly 
average basis because of circumstances beyond the applicant's control. 
Circumstances beyond the applicant's control may include seasonally 
dilute influent BOD concentrations due to relatively high (although 
nonexcessive) inflow and infiltration; relatively high soluble to 
insoluble BOD ratios on a fluctuating basis; or cold climates resulting 
in cold influent. Circumstances beyond the applicant's control shall not 
include less concentrated wastewater due to excessive inflow and 
infiltration (I&I). The determination of whether the less concentrated 
wastewater is the result of excessive I&I will be based on the 
definition of excessive I&I in 40 CFR 35.2005(b)(16) plus the additional 
criterion that inflow is nonexcessive if the total flow to the POTW 
(i.e., wastewater plus inflow plus infiltration) is less than 275 
gallons per capita per day.
    (2) In no event shall averaging on a less frequent basis than 
annually be allowed.

[59 FR 40658, Aug. 9, 1994, as amended at 61 FR 45833, Aug. 29, 1996]



Sec. 125.61  Existence of and compliance with applicable water
quality standards.

    (a) There must exist a water quality standard or standards 
applicable to the pollutant(s) for which a section 301(h) modified 
permit is requested, including:
    (1) Water quality standards for biochemical oxygen demand or 
dissolved oxygen;
    (2) Water quality standards for suspended solids, turbidity, light 
transmission, light scattering, or maintenance of the euphotic zone; and
    (3) Water quality standards for pH.
    (b) The applicant must: (1) Demonstrate that the modified discharge 
will comply with the above water quality standard(s); and
    (2) Provide a determination signed by the State or interstate 
agency(s) authorized to provide certification under Sec. Sec. 124.53 
and 124.54 that the proposed modified discharge will comply with 
applicable provisions of State law including water quality standards. 
This determination shall include a discussion of the basis for the 
conclusion reached.



Sec. 125.62  Attainment or maintenance of water quality which assures
protection of public water supplies; assures the protection 
and propagation of a balanced indigenous population of shellfish,
fish, and wildlife; and allows recreational activities.

    (a) Physical characteristics of discharge. (1) At the time the 
301(h) modification becomes effective, the applicant's outfall and 
diffuser must be located and designed to provide adequate initial 
dilution, dispersion, and transport of wastewater such that the 
discharge does not exceed at and beyond the zone of initial dilution:
    (i) All applicable water quality standards; and
    (ii) All applicable EPA water quality criteria for pollutants for 
which there is no applicable EPA-approved water quality standard that 
directly corresponds to the EPA water quality criterion for the 
pollutant.
    (iii) For purposes of paragraph (a)(1)(ii) of this section, a State 
water quality standard ``directly corresponds'' to an EPA water quality 
criterion only if:
    (A) The State water quality standard addresses the same pollutant as 
the EPA water quality criterion and
    (B) The State water quality standard specifies a numeric criterion 
for that pollutant or State objective methodology for deriving such a 
numeric criterion.
    (iv) The evaluation of compliance with paragraphs (a)(1) (i) and 
(ii) of this section shall be based upon conditions reflecting periods 
of maximum stratification and during other periods when

[[Page 377]]

discharge characteristics, water quality, biological seasons, or 
oceanographic conditions indicate more critical situations may exist.
    (2) The evaluation under paragraph (a)(1)(ii) of this section as to 
compliance with applicable section 304(a)(1) water quality criteria 
shall be based on the following:
    (i) For aquatic life criteria: The pollutant concentrations that 
must not be exceeded are the numeric ambient values, if any, specified 
in the EPA section 304(a)(1) water quality criteria documents as the 
concentrations at which acute and chronic toxicity to aquatic life 
occurs or that are otherwise identified as the criteria to protect 
aquatic life.
    (ii) For human health criteria for carcinogens: (A) For a known or 
suspected carcinogen, the Administrator shall determine the pollutant 
concentration that shall not be exceeded. To make this determination, 
the Administrator shall first determine a level of risk associated with 
the pollutant that is acceptable for purposes of this section. The 
Administrator shall then use the information in the section 304(a)(1) 
water quality criterion document, supplemented by all other relevant 
information, to determine the specific pollutant concentration that 
corresponds to the identified risk level.
    (B) For purposes of paragraph (a)(2)(ii)(A) of this section, an 
acceptable risk level will be a single level that has been consistently 
used, as determined by the Administrator, as the basis of the State's 
EPA-approved water quality standards for carcinogenic pollutants. 
Alternatively, the Administrator may consider a State's recommendation 
to use a risk level that has been otherwise adopted or formally proposed 
by the State. The State recommendation must demonstrate, to the 
satisfaction of the Administrator, that the recommended level is 
sufficiently protective of human health in light of the exposure and 
uncertainty factors associated with the estimate of the actual risk 
posed by the applicant's discharge. The State must include with its 
demonstration a showing that the risk level selected is based on the 
best information available and that the State has held a public hearing 
to review the selection of the risk level, in accordance with provisions 
of State law and public participation requirements of 40 CFR part 25. If 
the Administrator neither determines that there is a consistently used 
single risk level nor accepts a risk level recommended by the State, 
then the Administrator shall otherwise determine an acceptable risk 
level based on all relevant information.
    (iii) For human health criteria for noncarcinogens: For 
noncarcinogenic pollutants, the pollutant concentrations that must not 
be exceeded are the numeric ambient values, if any, specified in the EPA 
section 304(a)(1) water quality criteria documents as protective against 
the potential toxicity of the contaminant through ingestion of 
contaminated aquatic organisms.
    (3) The requirements of paragraphs (a)(1) and (a)(2) of this section 
apply in addition to, and do not waive or substitute for, the 
requirements of Sec. 125.61.
    (b) Impact of discharge on public water supplies. (1) The 
applicant's modified discharge must allow for the attainment or 
maintenance of water quality which assures protection of public water 
supplies.
    (2) The applicant's modified discharge must not:
    (i) Prevent a planned or existing public water supply from being 
used, or from continuing to be used, as a public water supply; or
    (ii) Have the effect of requiring treatment over and above that 
which would be necessary in the absence of such discharge in order to 
comply with local and EPA drinking water standards.
    (c) Biological impact of discharge. (1) The applicant's modified 
discharge must allow for the attainment or maintenance of water quality 
which assures protection and propagation of a balanced indigenous 
population of shellfish, fish, and wildlife.
    (2) A balanced indigenous population of shellfish, fish, and 
wildlife must exist:
    (i) Immediately beyond the zone of initial dilution of the 
applicant's modified discharge; and
    (ii) In all other areas beyond the zone of initial dilution where 
marine life is actually or potentially affected by the applicant's 
modified discharge.

[[Page 378]]

    (3) Conditions within the zone of initial dilution must not 
contribute to extreme adverse biological impacts, including, but not 
limited to, the destruction of distinctive habitats of limited 
distribution, the presence of disease epicenter, or the stimulation of 
phytoplankton blooms which have adverse effects beyond the zone of 
initial dilution.
    (4) In addition, for modified discharges into saline estuarine 
water:
    (i) Benthic populations within the zone of initial dilution must not 
differ substantially from the balanced indigenous populations which 
exist immediately beyond the boundary of the zone of initial dilution;
    (ii) The discharge must not interfere with estuarine migratory 
pathways within the zone of initial dilution; and
    (iii) The discharge must not result in the accumulation of toxic 
pollutants or pesticides at levels which exert adverse effects on the 
biota within the zone of initial dilution.
    (d) Impact of discharge on recreational activities. (1) The 
applicant's modified discharge must allow for the attainment or 
maintenance of water quality which allows for recreational activities 
beyond the zone of initial dilution, including, without limitation, 
swimming, diving, boating, fishing, and picnicking, and sports 
activities along shorelines and beaches.
    (2) There must be no Federal, State, or local restrictions on 
recreational activities within the vicinity of the applicant's modified 
outfall unless such restrictions are routinely imposed around sewage 
outfalls. This exception shall not apply where the restriction would be 
lifted or modified, in whole or in part, if the applicant were 
discharging a secondary treatment effluent.
    (e) Additional requirements for applications based on improved or 
altered discharges. An application for a section 301(h) modified permit 
on the basis of an improved or altered discharge must include:
    (1) A demonstration that such improvements or alterations have been 
thoroughly planned and studied and can be completed or implemented 
expeditiously;
    (2) Detailed analyses projecting changes in average and maximum 
monthly flow rates and composition of the applicant's discharge which 
are expected to result from proposed improvements or alterations;
    (3) The assessments required by paragraphs (a) through (d) of this 
section based on its current discharge; and
    (4) A detailed analysis of how the applicant's planned improvements 
or alterations will comply with the requirements of paragraphs (a) 
through (d) of this section.
    (f) Stressed waters. An applicant must demonstrate compliance with 
paragraphs (a) through (e) of this section not only on the basis of the 
applicant's own modified discharge, but also taking into account the 
applicant's modified discharge in combination with pollutants from other 
sources. However, if an applicant which discharges into ocean waters 
believes that its failure to meet the requirements of paragraphs (a) 
through (e) of this section is entirely attributable to conditions 
resulting from human perturbations other than its modified discharge 
(including, without limitation, other municipal or industrial 
discharges, nonpoint source runoff, and the applicant's previous 
discharges), the applicant need not demonstrate compliance with those 
requirements if it demonstrates, to the satisfaction of the 
Administrator, that its modified discharge does not or will not:
    (1) Contribute to, increase, or perpetuate such stressed conditions;
    (2) Contribute to further degradation of the biota or water quality 
if the level of human perturbation from other sources increases; and
    (3) Retard the recovery of the biota or water quality if the level 
of human perturbation from other sources decreases.



Sec. 125.63  Establishment of a monitoring program.

    (a) General requirements. (1) The applicant must:
    (i) Have a monitoring program that is:
    (A) Designed to provide data to evaluate the impact of the modified 
discharge on the marine biota, demonstrate compliance with applicable

[[Page 379]]

water quality standards or water quality criteria, as applicable, and 
measure toxic substances in the discharge, and
    (B) Limited to include only those scientific investigations 
necessary to study the effects of the proposed discharge;
    (ii) Describe the sampling techniques, schedules and locations 
(including appropriate control sites), analytical techniques, quality 
control and verification procedures to be used in the monitoring 
program;
    (iii) Demonstrate that it has the resources necessary to implement 
the program upon issuance of the modified permit and to carry it out for 
the life of the modified permit; and
    (iv) Determine the frequency and extent of the monitoring program 
taking into consideration the applicant's rate of discharge, quantities 
of toxic pollutants discharged, and potentially significant impacts on 
receiving water quality, marine biota, and designated water uses.
    (2) The Administrator may require revision of the proposed 
monitoring program before issuing a modified permit and during the term 
of any modified permit.
    (b) Biological monitoring program. The biological monitoring program 
for both small and large applicants shall provide data adequate to 
evaluate the impact of the modified discharge on the marine biota.
    (1) Biological monitoring shall include to the extent practicable:
    (i) Periodic surveys of the biological communities and populations 
which are most likely affected by the discharge to enable comparisons 
with baseline conditions described in the application and verified by 
sampling at the control stations/reference sites during the periodic 
surveys;
    (ii) Periodic determinations of the accumulation of toxic pollutants 
and pesticides in organisms and examination of adverse effects, such as 
disease, growth abnormalities, physiological stress, or death;
    (iii) Sampling of sediments in areas of solids deposition in the 
vicinity of the ZID, in other areas of expected impact, and at 
appropriate reference sites to support the water quality and biological 
surveys and to measure the accumulation of toxic pollutants and 
pesticides; and
    (iv) Where the discharge would affect commercial or recreational 
fisheries, periodic assessments of the conditions and productivity of 
fisheries.
    (2) Small applicants are not subject to the requirements of 
paragraph (b)(1) (ii) through (iv) of this section if they discharge at 
depths greater than 10 meters and can demonstrate through a suspended 
solids deposition analysis that there will be negligible seabed 
accumulation in the vicinity of the modified discharge.
    (3) For applicants seeking a section 301(h) modified permit based 
on:
    (i) A current discharge, biological monitoring shall be designed to 
demonstrate ongoing compliance with the requirements of Sec. 125.62(c);
    (ii) An improved discharge or altered discharge other than outfall 
relocation, biological monitoring shall provide baseline data on the 
current impact of the discharge and data which demonstrate, upon 
completion of improvements or alterations, that the requirements of 
Sec. 125.62(c) are met; or
    (iii) An improved or altered discharge involving outfall relocation, 
the biological monitoring shall:
    (A) Include the current discharge site until such discharge ceases; 
and
    (B) Provide baseline data at the relocation site to demonstrate the 
impact of the discharge and to provide the basis for demonstrating that 
requirements of Sec. 125.62(c) will be met.
    (c) Water quality monitoring program. The water quality monitoring 
program shall to the extent practicable:
    (1) Provide adequate data for evaluating compliance with water 
quality standards or water quality criteria, as applicable under Sec. 
125.62(a)(1);
    (2) Measure the presence of toxic pollutants which have been 
identified or reasonably may be expected to be present in the discharge.
    (d) Effluent monitoring program. (1) In addition to the requirements 
of 40 CFR part 122, to the extent practicable, monitoring of the POTW 
effluent shall provide quantitative and qualitative data which measure 
toxic substances and pesticides in the effluent and the effectiveness of 
the toxic control program.

[[Page 380]]

    (2) The permit shall require the collection of data on a frequency 
specified in the permit to provide adequate data for evaluating 
compliance with the percent removal efficiency requirements under Sec. 
125.60.



Sec. 125.64  Effect of the discharge on other point and nonpoint
sources.

    (a) No modified discharge may result in any additional pollution 
control requirements on any other point or nonpoint source.
    (b) The applicant shall obtain a determination from the State or 
interstate agency(s) having authority to establish wasteload allocations 
indicating whether the applicant's discharge will result in an 
additional treatment pollution control, or other requirement on any 
other point or nonpoint sources. The State determination shall include a 
discussion of the basis for its conclusion.



Sec. 125.65  Urban area pretreatment program.

    (a) Scope and applicability. (1) The requirements of this section 
apply to each POTW serving a population of 50,000 or more that has one 
or more toxic pollutants introduced into the POTW by one or more 
industrial dischargers and that seeks a section 301(h) modification.
    (2) The requirements of this section apply in addition to any 
applicable requirements of 40 CFR part 403, and do not waive or 
substitute for the part 403 requirements in any way.
    (b) Toxic pollutant control. (1) As to each toxic pollutant 
introduced by an industrial discharger, each POTW subject to the 
requirements of this section shall demonstrate that it either:
    (i) Has an applicable pretreatment requirement in effect in 
accordance with paragraph (c) of this section; or
    (ii) Has in effect a program that achieves secondary removal 
equivalency in accordance with paragraph (d) of this section.
    (2) Each applicant shall demonstrate that industrial sources 
introducing waste into the applicant's treatment works are in compliance 
with all applicable pretreatment requirements, including numerical 
standards set by local limits, and that it will enforce those 
requirements.
    (c) Applicable pretreatment requirement. (1) An applicable 
pretreatment requirement under paragraph (b)(1)(i) of this section with 
respect to a toxic pollutant shall consist of the following:
    (i) As to a toxic pollutant introduced into the applicant's 
treatment works by an industrial discharger for which there is no 
applicable categorical pretreatment standard for the toxic pollutant, a 
local limit or limits on the toxic pollutant as necessary to satisfy the 
requirements of 40 CFR part 403; and
    (ii) As to a toxic pollutant introduced into the applicant's 
treatment works by an industrial discharger that is subject to a 
categorical pretreatment standard for the toxic pollutant, the 
categorical standard and a local limit or limits as necessary to satisfy 
the requirements of 40 CFR part 403;
    (iii) As to a toxic pollutant introduced into the applicant's 
treatment works by an industrial discharger for which there is no 
applicable categorical pretreatment standard for the toxic pollutant, 
and the 40 CFR part 403 analysis on the toxic pollutant shows that no 
local limit is necessary, the applicant shall demonstrate to EPA on an 
annual basis during the term of the permit through continued monitoring 
and appropriate technical review that a local limit is not necessary, 
and, where appropriate, require industrial management practices plans 
and other pollution prevention activities to reduce or control the 
discharge of each such pollutant by industrial dischargers to the POTW. 
If such monitoring and technical review of data indicate that a local 
limit is needed, the POTW shall establish and implement a local limit.
    (2) Any local limits developed to meet the requirements of 
paragraphs (b)(1)(i) and (c)(1) of this section shall be:
    (i) Consistent with all applicable requirements of 40 CFR part 403 
and
    (ii) Subject to approval by the Administrator as part of the 301(h) 
application review. The Administrator may require such local limits to 
be revised as necessary to meet the requirements of this section or 40 
CFR part 403.

[[Page 381]]

    (d) Secondary removal equivalency. An applicant shall demonstrate 
that it achieves secondary removal equivalency through the use of a 
secondary treatment pilot (demonstration) plant at the applicant's 
facility which provides an empirical determination of the amount of a 
toxic pollutant removed by the application of secondary treatment to the 
applicant's influent where the applicant's influent has not been 
pretreated. Alternatively, an applicant may make this determination 
using influent that has received industrial pretreatment, 
notwithstanding the definition of secondary removal equivalency in Sec. 
125.58(w). The NPDES permit shall include effluent limits based on the 
data from the secondary equivalency demonstration when those limits are 
more stringent than effluent limits based on State water quality 
standards or water quality criteria, if applicable, or are otherwise 
required to assure that all applicable environmental protection criteria 
are met. Once such effluent limits are established in the NPDES permit, 
the POTW may either establish local limits or perform additional 
treatment at the POTW or a combination of the two to achieve the permit 
limit.



Sec. 125.66  Toxics control program.

    (a) Chemical analysis. (1) The applicant shall submit at the time of 
application a chemical analysis of its current discharge for all toxic 
pollutants and pesticides as defined in Sec. 125.58(aa) and (p). The 
analysis shall be performed on two 24-hour composite samples (one dry 
weather and one wet weather). Applicants may supplement or substitute 
chemical analyses if composition of the supplemental or substitute 
samples typifies that which occurs during dry and wet weather 
conditions.
    (2) Unless required by the State, this requirement shall not apply 
to any small section 301(h) applicant which certifies that there are no 
known or suspected sources of toxic pollutants or pesticides and 
documents the certification with an industrial user survey as described 
by 40 CFR 403.8(f)(2).
    (b) Identification of sources. The applicant shall submit at the 
time of application an analysis of the known or suspected sources of 
toxic pollutants or pesticides identified in Sec. 125.66(a). The 
applicant shall to the extent practicable categorize the sources 
according to industrial and nonindustrial types.
    (c) Industrial pretreatment requirements. (1) An applicant that has 
known or suspected industrial sources of toxic pollutants shall have an 
approved pretreatment program in accordance with 40 CFR part 403.
    (2) This requirement shall not apply to any applicant which has no 
known or suspected industrial sources of toxic pollutants or pesticides 
and so certifies to the Administrator.
    (3) The pretreatment program submitted by the applicant under this 
section shall be subject to revision as required by the Administrator 
prior to issuing or renewing any section 301(h) modified permit and 
during the term of any such permit.
    (4) Implementation of all existing pretreatment requirements and 
authorities must be maintained through the period of development of any 
additional pretreatment requirements that may be necessary to comply 
with the requirements of this subpart.
    (d) Nonindustrial source control program. (1) The applicant shall 
submit a proposed public education program designed to minimize the 
entrance of nonindustrial toxic pollutants and pesticides into its 
POTW(s) which shall be implemented no later than 18 months after 
issuance of a 301(h) modified permit.
    (2) The applicant shall also develop and implement additional 
nonindustrial source control programs on the earliest possible schedule. 
This requirement shall not apply to a small applicant which certifies 
that there are no known or suspected water quality, sediment 
accumulation, or biological problems related to toxic pollutants or 
pesticides in its discharge.
    (3) The applicant's nonindustrial source control programs under 
paragraph (d)(2) of this section shall include the following schedules 
which are to be implemented no later than 18 months after issuance of a 
section 301(h) modified permit:

[[Page 382]]

    (i) A schedule of activities for identifying nonindustrial sources 
of toxic pollutants and pesticides; and
    (ii) A schedule for the development and implementation of control 
programs, to the extent practicable, for nonindustrial sources of toxic 
pollutants and pesticides.
    (4) Each proposed nonindustrial source control program and/or 
schedule submitted by the applicant under this section shall be subject 
to revision as determined by the Administrator prior to issuing or 
renewing any section 301(h) modified permit and during the term of any 
such permit.



Sec. 125.67  Increase in effluent volume or amount of pollutants
discharged.

    (a) No modified discharge may result in any new or substantially 
increased discharges of the pollutant to which the modification applies 
above the discharge specified in the section 301(h) modified permit.
    (b) Where pollutant discharges are attributable in part to combined 
sewer overflows, the applicant shall minimize existing overflows and 
prevent increases in the amount of pollutants discharged.
    (c) The applicant shall provide projections of effluent volume and 
mass loadings for any pollutants to which the modification applies in 5-
year increments for the design life of its facility.



Sec. 125.68  Special conditions for section 301(h) modified permits.

    Each section 301(h) modified permit issued shall contain, in 
addition to all applicable terms and conditions required by 40 CFR part 
122, the following:
    (a) Effluent limitations and mass loadings which will assure 
compliance with the requirements of this subpart;
    (b) A schedule or schedules of compliance for:

  Sec. Appendix to Subpart G of Part 125--Applicant Questionnaire for 
            Modification of Secondary Treatment Requirements

    OMB Control Number 2040-0088 Expires on 2/28/96 Public reporting 
burden for this collection of information is estimated to average 1,295 
- 19,552 hours per response, for small and large applicants, 
respectively. The reporting burden includes time for reviewing 
instructions, gathering data, including monitoring and toxics control 
activities, and completing and reviewing the questionnaire. Send 
comments regarding the burden estimate or any other aspect of this 
collection, including suggestions for reducing the burden, to Chief, 
Information Policy Branch, U.S. Environmental Protection Agency, 1200 
Pennsylvania Ave., NW. (2136), Washington, DC 20460 and Office of 
Management and Budget, Office of Information and Regulatory Affairs, 
Attn: Desk Officer for EPA, Washington, DC 20503.

                             I. Introduction

    1. This questionnaire is to be submitted by both small and large 
applicants for modification of secondary treatment requirements under 
section 301(h) of the Clean Water Act (CWA). A small applicant is 
defined as a POTW that has a contributing population to its wastewater 
treatment facility of less than 50,000 and a projected average dry 
weather flow of less than 5.0 million gallons per day (mgd, 0.22 cubic 
meters/sec) [40 CFR 125.58(c)]. A large applicant is defined as a POTW 
that has a population contributing to its wastewater treatment facility 
of at least 50,000 or a projected average dry weather flow of its 
discharge of at least 5.0 million gallons per day (mgd, 0.22 cubic 
meters/sec) [40 CFR 125.58(c)]. The questionnaire is in two sections, a 
general information and basic requirements section (part II) and a 
technical evaluation section (part III). Satisfactory completion by 
small and large dischargers of the appropriate questions of this 
questionnaire is necessary to enable EPA to determine whether the 
applicant's modified discharge meets the criteria of section 301(h)

[[Page 383]]

and EPA regulations (40 CFR part 125, subpart G).
    2. Most small applicants should be able to complete the 
questionnaire using available information. However, small POTWs with low 
initial dilution discharging into shallow waters or waters with poor 
dispersion and transport characteristics, discharging near distinctive 
and susceptible biological habitats, or discharging substantial 
quantities of toxics should anticipate the need to collect additional 
information and/or conduct additional analyses to demonstrate compliance 
with section 301(h) criteria. If there are questions in this regard, 
applicants should contact the appropriate EPA Regional Office for 
guidance.
    3. Guidance for responding to this questionnaire is provided by the 
newly amended section 301(h) technical support document. Where available 
information is incomplete and the applicant needs to collect additional 
data during the period it is preparing the application or a letter of 
intent, EPA encourages the applicant to consult with EPA prior to data 
collection and submission. Such consultation, particularly if the 
applicant provides a project plan, will help ensure that the proper data 
are gathered in the most efficient matter.
    4. The notation (L) means large applicants must respond to the 
question, and (S) means small applicants must respond.

    Section 316(a) of the Act provides that:

    ``With respect to any point source otherwise subject to the 
provisions of section 301 or section 306 of this Act, whenever the owner 
or operator of any such source, after opportunity for public hearing, 
can demonstrate to the satisfaction of the Administrator (or, if 
appropriate, the State) that any effluent limitation proposed for the 
control of the thermal component of any discharge from such source will 
require effluent limitations more stringent than necessary to assure the 
projection [sic] and propagation of a balanced, indigenous population of 
shellfish, fish and wildlife in and on the body of water into which the 
discharge is to be made, the Administrator (or, if appropriate, the 
State) may impose an effluent limitation under such sections on such 
plant, with respect to the thermal component of such discharge (taking 
into account the interaction of such thermal component with other 
pollutants), that will assure the protection and propagation of a 
balanced indigenous population of shellfish, fish and wildlife in and on 
that body of water.''


This subpart describes the factors, criteria and standards for the 
establishment of alternative thermal effluent limitations under section 
316(a) of the Act in permits issued under section 402(a) of the Act.



Sec. 125.71  Definitions.

    For the purpose of this subpart:
    (a) Alternative effluent limitations means all effluent limitations 
or standards of performance for the control of the thermal component of 
any discharge which are established under section 316(a) and this 
subpart.
    (b) Representative important species means species which are 
representative, in terms of their biological needs, of a balanced, 
indigenous community of shellfish, fish and wildlife in the body of 
water into which a discharge of heat is made.
    (c) The term balanced, indigenous community is synonymous with the 
term balanced, indigenous population in the Act and means a biotic 
community typically characterized by diversity, the capacity to sustain 
itself through cyclic seasonal changes, presence of necessary food chain 
species and by a lack of domination by pollution tolerant species. Such 
a community may include historically non-native species introduced in 
connection with a program of wildlife management and species whose 
presence or abundance results from substantial, irreversible 
environmental modifications. Normally, however, such a community will 
not include species whose presence or abundance is attributable to the 
introduction of pollutants that will be eliminated by compliance by all 
sources with section 301(b)(2) of the Act; and may not include species 
whose presence or abundance is attributable to alternative effluent 
limitations imposed pursuant to section 316(a).



Sec. 125.72  Early screening of applications for section 316(a) 
variances.

    (a) Any initial application for a section 316(a) variance shall 
include the following early screening information:
    (1) A description of the alternative effluent limitation requested;
    (2) A general description of the method by which the discharger 
proposes to demonstrate that the otherwise applicable thermal discharge 
effluent limitations are more stringent than necessary;
    (3) A general description of the type of data, studies, experiments 
and other information which the discharger intends to submit for the 
demonstration; and
    (4) Such data and information as may be available to assist the 
Director in selecting the appropriate representative important species.
    (b) After submitting the early screening information under paragraph 
(a) of this section, the discharger shall consult with the Director at 
the earliest practicable time (but not later than 30 days after the 
application is filed) to discuss the discharger's early screening 
information. Within 60 days after the application is filed, the 
discharger shall submit for the Director's approval a detailed plan of 
study which the discharger will undertake to support its section 316(a) 
demonstration. The discharger shall specify the nature

[[Page 389]]

and extent of the following type of information to be included in the 
plan of study: Biological, hydrographical and meteorological data; 
physical monitoring data; engineering or diffusion models; laboratory 
studies; representative important species; and other relevant 
information. In selecting representative important species, special 
consideration shall be given to species mentioned in applicable water 
quality standards. After the discharger submits its detailed plan of 
study, the Director shall either approve the plan or specify any 
necessary revisions to the plan. The discharger shall provide any 
additional information or studies which the Director subsequently 
determines necessary to support the demonstration, including such 
studies or inspections as may be necessary to select representative 
important species. The discharger may provide any additional information 
or studies which the discharger feels are appropriate to support the 
demonstration.
    (c) Any application for the renewal of a section 316(a) variance 
shall include only such information described in paragraphs (a) and (b) 
of this section as the Director requests within 60 days after receipt of 
the permit application.
    (d) The Director shall promptly notify the Secretary of Commerce and 
the Secretary of the Interior, and any affected State of the filing of 
the request and shall consider any timely recommendations they submit.
    (e) In making the demonstration the discharger shall consider any 
information or guidance published by EPA to assist in making such 
demonstrations.
    (f) If an applicant desires a ruling on a section 316(a) application 
before the ruling on any other necessary permit terms and conditions, 
(as provided by Sec. 124.65), it shall so request upon filing its 
application under paragraph (a) of this section. This request shall be 
granted or denied at the discretion of the Director.

    Note: At the expiration of the permit, any discharger holding a 
section 316(a) variance should be prepared to support the continuation 
of the variance with studies based on the discharger's actual operation 
experience.

FR 30913, May 15, 2000]



Sec. 125.73  Criteria and standards for the determination of 
alternative effluent limitations under section 316(a).

    (a) Thermal discharge effluent limitations or standards established 
in permits may be less stringent than those required by applicable 
standards and limitations if the discharger demonstrates to the 
satisfaction of the director that such effluent limitations are more 
stringent than necessary to assure the protection and propagation of a 
balanced, indigenous community of shellfish, fish and wildlife in and on 
the body of water into which the discharge is made. This demonstration 
must show that the alternative effluent limitation desired by the 
discharger, considering the cumulative impact of its thermal discharge 
together with all other significant impacts on the species affected, 
will assure the protection and propagation of a balanced indigenous 
community of shellfish, fish and wildlife in and on the body of water 
into which the discharge is to be made.
    (b) In determining whether or not the protection and propagation of 
the affected species will be assured, the Director may consider any 
information contained or referenced in any applicable thermal water 
quality criteria and thermal water quality information published by the 
Administrator under section 304(a) of the Act, or any other information 
he deems relevant.
    (c) (1) Existing dischargers may base their demonstration upon the 
absence of prior appreciable harm in lieu of predictive studies. Any 
such demonstrations shall show:
    (i) That no appreciable harm has resulted from the normal component 
of the discharge (taking into account the interaction of such thermal 
component with other pollutants and the additive effect of other thermal 
sources to a balanced, indigenous community of shellfish, fish and 
wildlife in and on the body of water into which the discharge has been 
made; or
    (ii) That despite the occurrence of such previous harm, the desired 
alternative effluent limitations (or appropriate modifications thereof) 
will nevertheless assure the protection and propagation of a balanced, 
indigenous

[[Page 390]]

community of shellfish, fish and wildlife in and on the body of water 
into which the discharge is made.
    (2) In determining whether or not prior appreciable harm has 
occurred, the Director shall consider the length of time in which the 
applicant has been discharging and the nature of the discharge.



Subpart I_Requirements Applicable to Cooling Water Intake Structures for 
             New Facilities Under Section 316(b) of the Act

    Source: 66 FR 65338, Dec. 18, 2001, unless otherwise noted.



Sec. 125.80  What are the purpose and scope of this subpart?

    (a) This subpart establishes requirements that apply to the 
location, design, construction, and capacity of cooling water intake 
structures at new facilities. The purpose of these requirements is to 
establish the best technology available for minimizing adverse 
environmental impact associated with the use of cooling water intake 
structures. These requirements are implemented through National 
Pollutant Discharge Elimination System (NPDES) permits issued under 
section 402 of the Clean Water Act (CWA).
    (b) This subpart implements section 316(b) of the CWA for new 
facilities. Section 316(b) of the CWA provides that any standard 
established pursuant to sections 301 or 306 of the CWA and applicable to 
a point source shall require that the location, design, construction, 
and capacity of cooling water intake structures reflect the best 
technology available for minimizing adverse environmental impact.
    (c) New facilities that do not meet the threshold requirements 
regarding amount of water withdrawn or percentage of water withdrawn for 
cooling water purposes in Sec. 125.81(a) must meet requirements 
determined on a case-by-case, best professional judgement (BPJ) basis.
    (d) Nothing in this subpart shall be construed to preclude or deny 
the right of any State or political subdivision of a State or any 
interstate agency under section 510 of the CWA to adopt or enforce any 
requirement with respect to control or abatement of pollution that is 
more stringent than those required by Federal law.



Sec. 125.81  Who is subject to this subpart?

    (a) This subpart applies to a new facility if it:
    (1) Is a point source that uses or proposes to use a cooling water 
intake structure;
    (2) Has at least one cooling water intake structure that uses at 
least 25 percent of the water it withdraws for cooling purposes as 
specified in paragraph (c) of this section; and
    (3) Has a design intake flow greater than two (2) million gallons 
per day (MGD).
    (b) Use of a cooling water intake structure includes obtaining 
cooling water by any sort of contract or arrangement with an independent 
supplier (or multiple suppliers) of cooling water if the supplier or 
suppliers withdraw(s) water from waters of the United States. Use of 
cooling water does not include obtaining cooling water from a public 
water system or the use of treated effluent that otherwise would be 
discharged to a water of the U.S. This provision is intended to prevent 
circumvention of these requirements by creating arrangements to receive 
cooling water from an entity that is not itself a point source.
    (c) The threshold requirement that at least 25 percent of water 
withdrawn be used for cooling purposes must be measured on an average 
monthly basis. A new facility meets the 25 percent cooling water 
threshold if, based on the new facility's design, any monthly average 
over a year for the percentage of cooling water withdrawn is expected to 
equal or exceed 25 percent of the total water withdrawn.
    (d) This subpart does not apply to facilities that employ cooling 
water intake structures in the offshore and coastal subcategories of the 
oil and gas extraction point source category as defined under 40 CFR 
435.10 and 40 CFR 435.40.

[[Page 391]]



Sec. 125.82  When must I comply with this subpart?

    You must comply with this subpart when an NPDES permit containing 
requirements consistent with this subpart is issued to you.



Sec. 125.83  What special definitions apply to this subpart?

    The following special definitions apply to this subpart:
    Annual mean flow means the average of daily flows over a calendar 
year. Historical data (up to 10 years) must be used where available.
    Closed-cycle recirculating system means a system designed, using 
minimized makeup and blowdown flows, to withdraw water from a natural or 
other water source to support contact and/or noncontact cooling uses 
within a facility. The water is usually sent to a cooling canal or 
channel, lake, pond, or tower to allow waste heat to be dissipated to 
the atmosphere and then is returned to the system. (Some facilities 
divert the waste heat to other process operations.) New source water 
(make-up water) is added to the system to replenish losses that have 
occurred due to blowdown, drift, and evaporation.
    Cooling water means water used for contact or noncontact cooling, 
including water used for equipment cooling, evaporative cooling tower 
makeup, and dilution of effluent heat content. The intended use of the 
cooling water is to absorb waste heat rejected from the process or 
processes used, or from auxiliary operations on the facility's premises. 
Cooling water that is used in a manufacturing process either before or 
after it is used for cooling is considered process water for the 
purposes of calculating the percentage of a new facility's intake flow 
that is used for cooling purposes in Sec. 125.81(c).
    Cooling water intake structure means the total physical structure 
and any associated constructed waterways used to withdraw cooling water 
from waters of the U.S. The cooling water intake structure extends from 
the point at which water is withdrawn from the surface water source up 
to, and including, the intake pumps.
    Design intake flow means the value assigned (during the facility's 
design) to the total volume of water withdrawn from a source water body 
over a specific time period.
    Design intake velocity means the value assigned (during the design 
of a cooling water intake structure) to the average speed at which 
intake water passes through the open area of the intake screen (or other 
device) against which organisms might be impinged or through which they 
might be entrained.
    Entrainment means the incorporation of all life stages of fish and 
shellfish with intake water flow entering and passing through a cooling 
water intake structure and into a cooling water system.
    Estuary means a semi-enclosed body of water that has a free 
connection with open seas and within which the seawater is measurably 
diluted with fresh water derived from land drainage. The salinity of an 
estuary exceeds 0.5 parts per thousand (by mass) but is typically less 
than 30 parts per thousand (by mass).
    Existing facility means any facility that is not a new facility.
    Freshwater river or stream means a lotic (free-flowing) system that 
does not receive significant inflows of water from oceans or bays due to 
tidal action. For the purposes of this rule, a flow-through reservoir 
with a retention time of 7 days or less will be considered a freshwater 
river or stream.
    Hydraulic zone of influence means that portion of the source 
waterbody hydraulically affected by the cooling water intake structure 
withdrawal of water.
    Impingement means the entrapment of all life stages of fish and 
shellfish on the outer part of an intake structure or against a 
screening device during periods of intake water withdrawal.
    Lake or reservoir means any inland body of open water with some 
minimum surface area free of rooted vegetation and with an average 
hydraulic retention time of more than 7 days. Lakes or reservoirs might 
be natural water bodies or impounded streams, usually fresh, surrounded 
by land or by land and a man-made retainer (e.g., a dam). Lakes or 
reservoirs might be fed by rivers, streams, springs, and/or local 
precipitation. Flow-through reservoirs

[[Page 392]]

with an average hydraulic retention time of 7 days or less should be 
considered a freshwater river or stream.
    Maximize means to increase to the greatest amount, extent, or degree 
reasonably possible.
    Minimize means to reduce to the smallest amount, extent, or degree 
reasonably possible.
    Natural thermal stratification means the naturally-occurring 
division of a waterbody into horizontal layers of differing densities as 
a result of variations in temperature at different depths.
    New facility means any building, structure, facility, or 
installation that meets the definition of a ``new source'' or ``new 
discharger'' in 40 CFR 122.2 and 122.29(b)(1), (2), and (4) and is a 
greenfield or stand-alone facility; commences construction after January 
17, 2002; and uses either a newly constructed cooling water intake 
structure, or an existing cooling water intake structure whose design 
capacity is increased to accommodate the intake of additional cooling 
water. New facilities include only ``greenfield'' and ``stand-alone'' 
facilities. A greenfield facility is a facility that is constructed at a 
site at which no other source is located, or that totally replaces the 
process or production equipment at an existing facility (see 40 CFR 
122.29(b)(1)(i) and (ii)). A stand-alone facility is a new, separate 
facility that is constructed on property where an existing facility is 
located and whose processes are substantially independent of the 
existing facility at the same site (see 40 CFR 122.29(b)(1)(iii)). New 
facility does not include new units that are added to a facility for 
purposes of the same general industrial operation (for example, a new 
peaking unit at an electrical generating station).
    (1) Examples of ``new facilities'' include, but are not limited to: 
the following scenarios:
    (i) A new facility is constructed on a site that has never been used 
for industrial or commercial activity. It has a new cooling water intake 
structure for its own use.
    (ii) A facility is demolished and another facility is constructed in 
its place. The newly-constructed facility uses the original facility's 
cooling water intake structure, but modifies it to increase the design 
capacity to accommodate the intake of additional cooling water.
    (iii) A facility is constructed on the same property as an existing 
facility, but is a separate and independent industrial operation. The 
cooling water intake structure used by the original facility is modified 
by constructing a new intake bay for the use of the newly constructed 
facility or is otherwise modified to increase the intake capacity for 
the new facility.
    (2) Examples of facilities that would not be considered a ``new 
facility'' include, but are not limited to, the following scenarios:
    (i) A facility in commercial or industrial operation is modified and 
either continues to use its original cooling water intake structure or 
uses a new or modified cooling water intake structure.
    (ii) A facility has an existing intake structure. Another facility 
(a separate and independent industrial operation), is constructed on the 
same property and connects to the facility's cooling water intake 
structure behind the intake pumps, and the design capacity of the 
cooling water intake structure has not been increased. This facility 
would not be considered a ``new facility'' even if routine maintenance 
or repairs that do not increase the design capacity were performed on 
the intake structure.
    Ocean means marine open coastal waters with a salinity greater than 
or equal to 30 parts per thousand (by mass).
    Source water means the water body (waters of the U.S.) from which 
the cooling water is withdrawn.
    Thermocline means the middle layer of a thermally stratified lake or 
reservoir. In this layer, there is a rapid decrease in temperatures.
    Tidal excursion means the horizontal distance along the estuary or 
tidal river that a particle moves during one tidal cycle of ebb and 
flow.
    Tidal river means the most seaward reach of a river or stream where 
the salinity is typically less than or equal to 0.5 parts per thousand 
(by mass) at a

[[Page 393]]

time of annual low flow and whose surface elevation responds to the 
effects of coastal lunar tides.

    (a) Any interested person may request that alternative requirements 
less stringent than those specified in Sec. 125.84(a) through (e) be 
imposed in the permit. The Director may establish alternative 
requirements less stringent than the requirements of Sec. 125.84(a) 
through (e) only if:
    (1) There is an applicable requirement under Sec. 125.84(a) through 
(e);
    (2) The Director determines that data specific to the facility 
indicate that compliance with the requirement at issue would result in 
compliance costs wholly out of proportion to the costs EPA considered in 
establishing the requirement at issue or would result in significant 
adverse impacts on local air quality, significant adverse impacts on 
local water resources other than impingement or entrainment, or 
significant adverse impacts on local energy markets;
    (3) The alternative requirement requested is no less stringent than 
justified by the wholly out of proportion cost or the significant 
adverse impacts on local air quality, significant adverse impacts on 
local water resources other than impingement or entrainment, or 
significant adverse impacts on local energy markets; and
    (4) The alternative requirement will ensure compliance with other 
applicable provisions of the Clean Water Act and any applicable 
requirement of state law.
    (b) The burden is on the person requesting the alternative 
requirement to demonstrate that alternative requirements should be 
authorized.

fisheries management agency(ies) with responsibility for fisheries 
potentially affected by your cooling water intake structure(s).
    (2) Track II Comprehensive Demonstration Study. You must perform and 
submit the results of a Comprehensive Demonstration Study (Study). This 
information is required to characterize the source water baseline in the 
vicinity of the cooling water intake structure(s), characterize 
operation of the cooling water intake(s), and to confirm that the 
technology(ies) proposed and/or implemented at your cooling water intake 
structure reduce the impacts to fish and shellfish to levels comparable 
to those you would achieve were you to implement the requirements in 
Sec. 125.84(b)(1)and (2) of Track I. To meet the ``comparable level'' 
requirement, you must demonstrate that:
    (i) You have reduced both impingement mortality and entrainment of

[[Page 398]]

that would be achieved through Sec. 125.84(b)(1) and (2); or
    (ii) [Reserved]
    (iii) You must develop and submit a plan to the Director containing 
a proposal for how information will be collected to support the study. 
The plan must include:
    (A) A description of the proposed and/or implemented technology(ies) 
to be evaluated in the Study;
    (B) A list and description of any historical studies characterizing 
the physical and biological conditions in the vicinity of the proposed 
or actual intakes and their relevancy to the proposed Study. If you 
propose to rely on existing source water body data, it must be no more 
than 5 years old, you must demonstrate that the existing data are 
sufficient to develop a scientifically valid estimate of potential 
impingement and entrainment impacts, and provide documentation showing 
that the data were collected using appropriate quality assurance/quality 
control procedures;
    (C) Any public participation or consultation with Federal or State 
agencies undertaken in developing the plan; and
    (D) A sampling plan for data that will be collected using actual 
field studies in the source water body. The sampling plan must document 
all methods and quality assurance procedures for sampling, and data 
analysis. The sampling and data analysis methods you propose must be 
appropriate for a quantitative survey and based on consideration of 
methods used in other studies performed in the source water body. The 
sampling plan must include a description of the study area (including 
the area of influence of the cooling water intake structure and at least 
100 meters beyond); taxonomic identification of the sampled or evaluated 
biological assemblages (including all life stages of fish and 
shellfish); and sampling and data analysis methods; and
    (iv) You must submit documentation of the results of the Study to 
the Director. Documentation of the results of the Study must include:
    (A) Source Water Biological Study. The Source Water Biological Study 
must include:
    (1) A taxonomic identification and characterization of aquatic 
biological resources including: a summary of historical and contemporary 
aquatic biological resources; determination and description of the 
target populations of concern (those species of fish and shellfish and 
all life stages that are most susceptible to impingement and 
entrainment); and a description of the abundance and temporal/spatial 
characterization of the target populations based on the collection of 
multiple years of data to capture the seasonal and daily activities 
(e.g., spawning, feeding and water column migration) of all life stages 
of fish and shellfish found in the vicinity of the cooling water intake 
structure;
    (2) An identification of all threatened or endangered species that 
might be susceptible to impingement and entrainment by the proposed 
cooling water intake structure(s); and
    (3) A description of additional chemical, water quality, and other 
anthropogenic stresses on the source waterbody.
    (B) Evaluation of potential cooling water intake structure effects. 
This evaluation will include:
    (1) Calculations of the reduction in impingement mortality and 
entrainment of all life stages of fish and shellfish that would need to 
be achieved by the technologies you have selected to implement to meet 
requirements under Track II. To do this, you must determine the 
reduction in impingement mortality and entrainment that would be 
achieved by implementing the requirements of Sec. 125.84(b)(1) and (2) 
of Track I at your site.
    (2) An engineering estimate of efficacy for the proposed and/or 
implemented technologies used to minimize impingement mortality and 
entrainment of all life stages of fish and shellfish and maximize 
survival of impinged life stages of fish and shellfish. You must 
demonstrate that the technologies reduce impingement mortality and 
entrainment of all life stages of fish and shellfish to a comparable 
level to that which you would achieve were you to implement the 
requirements in Sec. 125.84(b)(1) and (2) of Track I. The efficacy 
projection must include a site-specific evaluation of

[[Page 399]]

technology(ies) suitability for reducing impingement mortality and 
entrainment based on the results of the Source Water Biological Study in 
paragraph (c)(2)(iv)(A) of this section. Efficacy estimates may be 
determined based on case studies that have been conducted in the 
vicinity of the cooling water intake structure and/or site-specific 
technology prototype studies.
    (C) [Reserved]
    (D) Verification monitoring plan. You must include in the Study the 
following:
    (1) A plan to conduct, at a minimum, two years of monitoring to 
verify the full-scale performance of the proposed or implemented 
technologies, operational measures. The verification study must begin at 
the start of operations of the cooling water intake structure and 
continue for a sufficient period of time to demonstrate that the 
facility is reducing the level of impingement and entrainment to the 
level documented in paragraph (c)(2)(iv)(B) of this section. The plan 
must describe the frequency of monitoring and the parameters to be 
monitored. The Director will use the verification monitoring to confirm 
that you are meeting the level of impingement mortality and entrainment 
reduction required in Sec. 125.84(d), and that the operation of the 
technology has been optimized.

Sec. 125.87  As an owner or operator of a new facility, must I perform
monitoring?

    As an owner or operator of a new facility, you will be required to 
perform monitoring to demonstrate your compliance with the requirements 
specified in Sec. 125.84.
    (a) Biological monitoring. You must monitor both impingement and 
entrainment of the commercial, recreational, and forage base fish and 
shellfish species identified in either the Source Water Baseline 
Biological Characterization data required by 40 CFR 122.21(r)(4) or the 
Comprehensive Demonstration Study required by Sec. 125.86(c)(2), 
depending on whether you chose to comply with Track I or Track II. The 
monitoring methods used must be consistent with those used for the 
Source Water Baseline Biological Characterization data required in 40 
CFR 122.21(r)(4) or the Comprehensive Demonstration Study required by 
Sec. 125.86(c)(2). You must follow the monitoring frequencies 
identified below for at least two (2) years after the initial permit 
issuance. After that time, the Director may approve a request for less 
frequent sampling in the remaining years of the permit term and when the 
permit is reissued, if the Director determines the supporting data show 
that less frequent monitoring would still allow for the detection of any 
seasonal and daily variations in the species and numbers of individuals 
that are impinged or entrained.
    (1) Impingement sampling. You must collect samples to monitor 
impingement rates (simple enumeration) for each species over a 24-hour 
period and no less than once per month when the cooling water intake 
structure is in operation.
    (2) Entrainment sampling. You must collect samples at least biweekly 
to monitor entrainment rates (simple enumeration) for each species over 
a 24-hour period during the primary period of reproduction, larval 
recruitment, and peak abundance identified during the Source Water 
Baseline Biological Characterization required by 40 CFR 122.21(r)(4) or 
the Comprehensive Demonstration Study required in Sec. 125.86(c)(2). 
You must collect samples only when the cooling water intake structure is 
in operation.
    (b) Velocity monitoring. If your facility uses surface intake screen 
systems, you must monitor head loss across the screens and correlate the 
measured value with the design intake velocity. The head loss across the 
intake screen must be measured at the minimum ambient source water 
surface elevation (best professional judgment based on available 
hydrological data). The maximum head loss across the screen for each 
cooling water intake structure must be used to determine compliance with 
the velocity requirement in Sec. 125.84(b)(2) or (c)(1). If your 
facility uses devices other than surface intake screens, you must 
monitor velocity at the point of entry through the device.

[[Page 400]]

You must monitor head loss or velocity during initial facility startup, 
and thereafter, at the frequency specified in your NPDES permit, but no 
less than once per quarter.
    (c) Visual or remote inspections. You must either conduct visual 
inspections or employ remote monitoring devices during the period the 
cooling water intake structure is in operation. You must conduct visual 
inspections at least weekly to ensure that any design and construction 
technologies required in Sec. 125.84(b)(4) and (5), or (c)(3) and (4) 
are maintained and operated to ensure that they will continue to 
function as designed. Alternatively, you must inspect via remote 
monitoring devices to ensure that the impingement and entrainment 
technologies are functioning as designed.

[66 FR 65338, Dec. 18, 2001, as amended at 79 FR 48429, Aug. 15, 2014]



Sec. 125.88  As an owner or operator of a new facility, must I keep
records and report?

    As an owner or operator of a new facility you are required to keep 
records and report information and data to the Director as follows:
    (a) You must keep records of all the data used to complete the 
permit application and show compliance with the requirements, any 
supplemental information developed under Sec. 125.86, and any 
compliance monitoring data submitted under Sec. 125.87, for a period of 
at least three (3) years from the date of permit issuance. The Director 
may require that these records be kept for a longer period.
    (b) You must provide the following to the Director in a yearly 
status report:
    (1) Biological monitoring records for each cooling water intake 
structure as required by Sec. 125.87(a);
    (2) Velocity and head loss monitoring records for each cooling water 
intake structure as required by Sec. 125.87(b); and
    (3) Records of visual or remote inspections as required in Sec. 
125.87(c).



Sec. 125.89  As the Director, what must I do to comply with the
requirements of this subpart?

    (a) Permit application. As the Director, you must review materials 
submitted by the applicant under 40 CFR 122.21(r)(4) and Sec. 125.86 at 
the time of the initial permit application and before each permit 
renewal or reissuance.
    (1) After receiving the initial permit application from the owner or 
operator of a new facility, the Director must determine applicable 
standards in Sec. 125.84 to apply to the new facility. In addition, the 
Director must review materials to determine compliance with the 
applicable standards.
    (2) For each subsequent permit renewal, the Director must review the 
application materials and monitoring data to determine whether 
requirements, or additional requirements, for design and construction 
technologies or operational measures should be included in the permit.
    (3) For Track II facilities, the Director may review the information 
collection proposal plan required by Sec. 125.86(c)(2)(iii). The 
facility may initiate sampling and data collection activities prior to 
receiving comment from the Director.
    (b) Permitting requirements. Section 316(b) requirements are 
implemented for a facility through an NPDES permit. As the Director, you 
must determine, based on the information submitted by the new facility 
in its permit application, the appropriate requirements and conditions 
to include in the permit based on the track (Track I or Track II) the 
new facility has chosen to comply with. The following requirements must 
be included in each permit:
    (1) Cooling water intake structure requirements. At a minimum, the 
permit conditions must include the performance standards that implement 
the requirements of Sec. 125.84(b)(1), (2), (3), (4) and (5); Sec. 
125.84(c)(1), (2), (3) and (4); or Sec. 125.84(d)(1) and (2). In 
determining compliance with proportional flow requirement in Sec. Sec. 
125.84(b)(3)(ii); (c)(2)(ii); and (d)(2)(ii), the director must consider 
anthropogenic factors (those not considered ``natural'') unrelated to 
the new facility's cooling water intake structure that can influence the 
occurrence and location of a thermocline. These include source water 
inflows, other water withdrawals, managed water uses, wastewater 
discharges, and flow/level management practices (e.g., some reservoirs 
release water from

[[Page 401]]

below the surface, close to the deepest areas).
    (i) If an owner or operator of a facility chooses Track I, you must 
review the Design and Construction Technology Plan required in Sec. 
125.86(b)(4) to evaluate the suitability and feasibility of the 
technology proposed to minimize impingement mortality and entrainment of 
all life stages of fish and shellfish. In the first permit issued, you 
must put a condition requiring the facility to reduce impingement 
mortality and entrainment commensurate with the implementation of the 
technologies in the permit. Under subsequent permits, the Director must 
review the performance of the technologies implemented and require 
additional or different design and construction technologies, if needed 
to minimize impingement mortality and entrainment of all life stages of 
fish and shellfish. In addition, you must consider whether more 
stringent conditions are reasonably necessary in accordance with Sec. 
125.84(e).
    (ii) If an owner or operator of a facility chooses Track II, you 
must review the information submitted with the Comprehensive 
Demonstration Study required in Sec. 125.86(c)(2) and evaluate the 
suitability of the proposed design and construction technologies and 
operational measures to determine whether they will reduce both 
impingement mortality and entrainment of all life stages of fish and 
shellfish to 90 percent or greater of the reduction that could be 
achieved through Track I. In addition, you must review the Verification 
Monitoring Plan in Sec. 125.86(c)(2)(iv)(D) and require that the 
proposed monitoring begin at the start of operations of the cooling 
water intake structure and continue for a sufficient period of time to 
demonstrate that the technologies and operational measures meet the 
requirements in Sec. 125.84(d)(1). Under subsequent permits, the 
Director must review the performance of the additional and/or different 
technologies or measures used and determine that they reduce the level 
of adverse environmental impact from the cooling water intake structures 
to a comparable level that the facility would achieve were it to 
implement the requirements of Sec. 125.84(b)(1) and (2).
    (2) Monitoring conditions. At a minimum, the permit must require the 
permittee to perform the monitoring required in Sec. 125.87. You may 
modify the monitoring program when the permit is reissued and during the 
term of the permit based on changes in physical or biological conditions 
in the vicinity of the cooling water intake structure. The Director may 
require continued monitoring based on the results of the Verification 
Monitoring Plan in Sec. 125.86(c)(2)(iv)(D).
    (3) Record keeping and reporting. At a minimum, the permit must 
require the permittee to report and keep records as required by Sec. 
125.88.

Subpart J_Requirements Applicable to Cooling Water Intake Structures for 
     Existing Facilities Under Section 316(b) of the Clean Water Act

    Source: 79 FR 48430, Aug. 15, 2014, unless otherwise noted.



Sec. 125.90  Purpose of this subpart.

    (a) This subpart establishes the section 316(b) requirements that 
apply to cooling water intake structures at existing facilities that are 
subject to this subpart. These requirements include a number of 
components. These include standards for minimizing adverse environmental 
impact associated with the use of cooling water intake structures and 
required procedures (e.g., permit application requirements, information 
submission requirements) for establishing the appropriate technology 
requirements at certain specified facilities as well as monitoring, 
reporting, and recordkeeping requirements to demonstrate compliance. In 
combination, these components represent the best technology available 
for minimizing adverse environmental impact associated with the use of 
cooling water intake structures at existing facilities. These 
requirements are to be established and implemented in National Pollutant 
Discharge Elimination

[[Page 402]]

System (NPDES) permits issued under the Clean Water Act (CWA).
    (b) Cooling water intake structures not subject to requirements 
under Sec. Sec. 125.94 through 125.99 or subparts I or N of this part 
must meet requirements under section 316(b) of the CWA established by 
the Director on a case-by-case, best professional judgment (BPJ) basis.
    (c) Nothing in this subpart shall be construed to preclude or deny 
the right under section 510 of the CWA of any State or political 
subdivision of a State or any interstate agency to adopt or enforce any 
requirement with respect to control or abatement of pollution that is 
more stringent than required by Federal law.
    Note to Sec. 125.90. This regulation does not authorize take, as 
defined by the Endangered Species Act, 16 U.S.C. 1532(19). The U.S. Fish 
and Wildlife Service and National Marine Fisheries Service have 
determined that any impingement (including entrapment) or entrainment of 
Federally-listed species constitutes take. Such take may be authorized 
pursuant to the conditions of a permit issued under 16 U.S.C. 1539(a) or 
where consistent with an Incidental Take Statement contained in a 
Biological Opinion pursuant to 16 U.S.C. 1536(o).



Sec. 125.91  Applicability.

    (a) The owner or operator of an existing facility, as defined in 
Sec. 125.92(k), is subject to the requirements at Sec. Sec. 125.94 
through 125.99 if:
    (1) The facility is a point source;
    (2) The facility uses or proposes to use one or more cooling water 
intake structures with a cumulative design intake flow (DIF) of greater 
than 2 million gallons per day (mgd) to withdraw water from waters of 
the United States; and
    (3) Twenty-five percent or more of the water the facility withdraws 
on an actual intake flow basis is used exclusively for cooling purposes.
    (b) Use of a cooling water intake structure includes obtaining 
cooling water by any sort of contract or arrangement with one or more 
independent suppliers of cooling water if the independent supplier 
withdraws water from waters of the United States but is not itself a new 
or existing facility as defined in subparts I or J of this part, except 
as provided in paragraphs (c) and (d) of this section. An owner or 
operator of an existing facility may not circumvent these requirements 
by creating arrangements to receive cooling water from an entity that is 
not itself a facility subject to subparts I or J of this part.
    (c) Obtaining cooling water from a public water system, using 
reclaimed water from wastewater treatment facilities or desalination 
plants, or recycling treated process wastewater effluent as cooling 
water does not constitute use of a cooling water intake structure for 
purposes of this subpart.
    (d) This subpart does not apply to offshore seafood processing 
facilities, offshore liquefied natural gas terminals, and offshore oil 
and gas extraction facilities that are existing facilities as defined in 
Sec. 125.92(k). The owners and operators of such facilities must meet 
requirements established by the Director on a case-by-case, best 
professional judgment (BPJ) basis.



Sec. 125.92  Special definitions.

    In addition to the definitions provided in 40 CFR 122.2, the 
following special definitions apply to this subpart:
    (a) Actual Intake Flow (AIF) means the average volume of water 
withdrawn on an annual basis by the cooling water intake structures over 
the past three years. After October 14, 2019, Actual Intake Flow means 
the average volume of water withdrawn on an annual basis by the cooling 
water intake structures over the previous five years. Actual intake flow 
is measured at a location within the cooling water intake structure that 
the Director deems appropriate. The calculation of actual intake flow 
includes days of zero flow. AIF does not include flows associated with 
emergency and fire suppression capacity.
    (b) All life stages of fish and shellfish means eggs, larvae, 
juveniles, and adults. It does not include members of the infraclass 
Cirripedia in the subphylum Crustacea (barnacles), green mussels (Perna 
viridis), or zebra mussels (Dreissena polymorpha). The Director may 
determine that all life stages of

[[Page 403]]

fish and shellfish does not include other specified nuisance species.
    (c) Closed-cycle recirculating system means a system designed and 
properly operated using minimized make-up and blowdown flows withdrawn 
from a water of the United States to support contact or non-contact 
cooling uses within a facility, or a system designed to include certain 
impoundments. A closed-cycle recirculating system passes cooling water 
through the condenser and other components of the cooling system and 
reuses the water for cooling multiple times.
    (1) Closed-cycle recirculating system includes a facility with wet, 
dry, or hybrid cooling towers, a system of impoundments that are not 
waters of the United States, or any combination thereof. A properly 
operated and maintained closed-cycle recirculating system withdraws new 
source water (make-up water) only to replenish losses that have occurred 
due to blowdown, drift, and evaporation. If waters of the United States 
are withdrawn for purposes of replenishing losses to a closed-cycle 
recirculating system other than those due to blowdown, drift, and 
evaporation from the cooling system, the Director may determine a 
cooling system is a closed-cycle recirculating system if the facility 
demonstrates to the satisfaction of the Director that make-up water 
withdrawals attributed specifically to the cooling portion of the 
cooling system have been minimized.
    (2) Closed-cycle recirculating system also includes a system with 
impoundments of waters of the U.S. where the impoundment was constructed 
prior to October 14, 2014 and created for the purpose of serving as part 
of the cooling water system as documented in the project purpose 
statement for any required Clean Water Act section 404 permit obtained 
to construct the impoundment. In the case of an impoundment whose 
construction pre-dated the CWA requirement to obtain a section 404 
permit, documentation of the project's purpose must be demonstrated to 
the satisfaction of the Director. This documentation could be some other 
license or permit obtained to lawfully construct the impoundment for the 
purposes of a cooling water system, or other such evidence as the 
Director finds necessary. For impoundments constructed in uplands or not 
in waters of the United States, no documentation of a section 404 or 
other permit is required. If waters of the United States are withdrawn 
for purposes of replenishing losses to a closed-cycle recirculating 
system other than those due to blowdown, drift, and evaporation from the 
cooling system, the Director may determine a cooling system is a closed-
cycle recirculating system if the facility demonstrates to the 
satisfaction of the Director that make-up water withdrawals attributed 
specifically to the cooling portion of the cooling system have been 
minimized.
    (d) Contact cooling water means water used for cooling which comes 
into direct contact with any raw material, product, or byproduct. 
Examples of contact cooling water may include but are not limited to 
quench water at facilities, cooling water in a cracking unit, and 
cooling water directly added to food and agricultural products 
processing.
    (e) Cooling water means water used for contact or non-contact 
cooling, including water used for equipment cooling, evaporative cooling 
tower makeup, and dilution of effluent heat content. The intended use of 
the cooling water is to absorb waste heat rejected from the process or 
processes used, or from auxiliary operations on the facility's premises. 
Cooling water obtained from a public water system, reclaimed water from 
wastewater treatment facilities or desalination plants, treated effluent 
from a manufacturing facility, or cooling water that is used in a 
manufacturing process either before or after it is used for cooling as 
process water, is not considered cooling water for the purposes of 
calculating the percentage of a facility's intake flow that is used for 
cooling purposes in Sec. 125.91(a)(3).
    (f) Cooling water intake structure means the total physical 
structure and any associated constructed waterways used to withdraw 
cooling water from waters of the United States. The cooling water intake 
structure extends from the point at which water is first withdrawn from 
waters of the United States up to, and including the intake pumps.

[[Page 404]]

    (g) Design intake flow (DIF) means the value assigned during the 
cooling water intake structure design to the maximum instantaneous rate 
of flow of water the cooling water intake system is capable of 
withdrawing from a source waterbody. The facility's DIF may be adjusted 
to reflect permanent changes to the maximum capabilities of the cooling 
water intake system to withdraw cooling water, including pumps 
permanently removed from service, flow limit devices, and physical 
limitations of the piping. DIF does not include values associated with 
emergency and fire suppression capacity or redundant pumps (i.e., back-
up pumps).
    (h) Entrainment means any life stages of fish and shellfish in the 
intake water flow entering and passing through a cooling water intake 
structure and into a cooling water system, including the condenser or 
heat exchanger. Entrainable organisms include any organisms potentially 
subject to entrainment. For purposes of this subpart, entrainment 
excludes those organisms that are collected or retained by a sieve with 
maximum opening dimension of 0.56 inches. Examples of sieves meeting 
this definition include but are not limited to a \3/8\ inch square mesh, 
or a \1/2\ by \1/4\ inch mesh. A facility must use the same mesh size 
when counting entrainment as is used when counting impingement.
    (i) Entrainment mortality means death as a result of entrainment 
through the cooling water intake structure, or death as a result of 
exclusion from the cooling water intake structure by fine mesh screens 
or other protective devices intended to prevent the passage of 
entrainable organisms through the cooling water intake structure.
    (j) Entrapment means the condition where impingeable fish and 
shellfish lack the means to escape the cooling water intake. Entrapment 
includes but is not limited to: Organisms caught in the bucket of a 
traveling screen and unable to reach a fish return; organisms caught in 
the forebay of a cooling water intake system without any means of being 
returned to the source waterbody without experiencing mortality; or 
cooling water intake systems where the velocities in the intake pipes or 
in any channels leading to the forebay prevent organisms from being able 
to return to the source waterbody through the intake pipe or channel.
    (k) Existing facility means any facility that commenced construction 
as described in 40 CFR 122.29(b)(4) on or before January 17, 2002 (or 
July 17, 2006 for an offshore oil and gas extraction facility) and any 
modification of, or any addition of a unit at such a facility. A 
facility built adjacent to another facility would be a new facility 
while the original facility would remain as an exiting facility for 
purposes of this subpart. A facility cannot both be an existing facility 
and a new facility as defined at Sec. 125.83.
    (l) Flow reduction means any modification to a cooling water intake 
structure or its operation that serves to reduce the volume of cooling 
water withdrawn. Examples include, but are not limited to, variable 
speed pumps, seasonal flow reductions, wet cooling towers, dry cooling 
towers, hybrid cooling towers, unit closures, or substitution for 
withdrawals by reuse of effluent from a nearby facility.
    (m) Fragile species means those species of fish and shellfish that 
are least likely to survive any form of impingement. For purposes of 
this subpart, fragile species are defined as those with an impingement 
survival rate of less than 30 percent, including but not limited to 
alewife, American shad, Atlantic herring, Atlantic long-finned squid, 
Atlantic menhaden, bay anchovy, blueback herring, bluefish, butterfish, 
gizzard shad, grey snapper, hickory shad, menhaden, rainbow smelt, round 
herring, and silver anchovy.
    (n) Impingement means the entrapment of any life stages of fish and 
shellfish on the outer part of an intake structure or against a 
screening device during periods of intake water withdrawal. For purposes 
of this subpart, impingement includes those organisms collected or 
retained on a sieve with maximum distance in the opening of 0.56 inches, 
and excludes those organisms that pass through the sieve. Examples of 
sieves meeting this definition include but are not limited to a \3/8\ 
inch square mesh, or a \1/2\ by \1/4\ inch mesh. This definition is 
intended to prevent the conversion of entrainable

[[Page 405]]

organisms to counts of impingement or impingement mortality. The owner 
or operator of a facility must use a sieve with the same mesh size when 
counting entrainment as is used when counting impingement.
    (o) Impingement mortality (IM) means death as a result of 
impingement. Impingement mortality also includes organisms removed from 
their natural ecosystem and lacking the ability to escape the cooling 
water intake system, and thus subject to inevitable mortality.
    (p) Independent supplier means an entity, other than the regulated 
facility, that owns and operates its own cooling water intake structure 
and directly withdraws water from waters of the United States. The 
supplier provides the cooling water to other facilities for their use, 
but may itself also use a portion of the water. An entity that provides 
potable water to residential populations (e.g., public water system) is 
not a supplier for purposes of this subpart.
    (q) Latent mortality means the delayed mortality of organisms that 
were initially alive upon being impinged or entrained but that do not 
survive the delayed effects of impingement and entrainment during an 
extended holding period. Delayed effects of impingement and entrainment 
include but are not limited to temperature change, physical stresses, 
and chemical stresses.
    (r) Minimize means to reduce to the smallest amount, extent, or 
degree reasonably possible.
    (s) Modified traveling screen means a traveling water screen that 
incorporates measures protective of fish and shellfish, including but 
not limited to: Screens with collection buckets or equivalent mechanisms 
designed to minimize turbulence to aquatic life; addition of a guard 
rail or barrier to prevent loss of fish from the collection system; 
replacement of screen panel materials with smooth woven mesh, drilled 
mesh, molded mesh, or similar materials that protect fish from descaling 
and other abrasive injury; continuous or near-continuous rotation of 
screens and operation of fish collection equipment to ensure any 
impinged organisms are recovered as soon as practical; a low pressure 
wash or gentle vacuum to remove fish prior to any high pressure spray to 
remove debris from the screens; and a fish handling and return system 
with sufficient water flow to return the fish directly to the source 
water in a manner that does not promote predation or re-impingement of 
the fish, or require a large vertical drop. The Director may approve of 
fish being returned to water sources other than the original source 
water, taking into account any recommendations from the Services with 
respect to endangered or threatened species. Examples of modified 
traveling screens include, but are not limited to: Modified Ristroph 
screens with a fish handling and return system, dual flow screens with 
smooth mesh, and rotary screens with fish returns or vacuum returns.
    (t) Moribund means dying; close to death.
    (u) New unit means a new ``stand-alone'' unit at an existing 
facility where construction of the new unit begins after October 14, 
2014 and that does not otherwise meet the definition of a new facility 
at Sec. 125.83 or is not otherwise already subject to subpart I of this 
part. A stand-alone unit is a separate unit that is added to a facility 
for either the same general industrial operation or another purpose. A 
new unit may have its own dedicated cooling water intake structure, or 
the new unit may use an existing or modified cooling water intake 
structure.
    (v) Offshore velocity cap means a velocity cap located a minimum of 
800 feet from the shoreline. A velocity cap is an open intake designed 
to change the direction of water withdrawal from vertical to horizontal, 
thereby creating horizontal velocity patterns that result in avoidance 
of the intake by fish and other aquatic organisms. For purposes of this 
subpart, the velocity cap must use bar screens or otherwise exclude 
marine mammals, sea turtles, and other large aquatic organisms.
    (w) Operational measure means a modification to any operation that 
serves to minimize impact to all life stages of fish and shellfish from 
the cooling water intake structure. Examples of operational measures 
include, but are not limited to, more frequent rotation of traveling 
screens, use of a low

[[Page 406]]

pressure wash to remove fish prior to any high pressure spray to remove 
debris, maintaining adequate volume of water in a fish return, and 
debris minimization measures such as air sparging of intake screens and/
or other measures taken to maintain the design intake velocity.
    (x) Social benefits means the increase in social welfare that 
results from taking an action. Social benefits include private benefits 
and those benefits not taken into consideration by private decision 
makers in the actions they choose to take, including effects occurring 
in the future. Benefits valuation involves measuring the physical and 
biological effects on the environment from the actions taken. Benefits 
are generally treated one or more of three ways: A narrative containing 
a qualitative discussion of environmental effects, a quantified analysis 
expressed in physical or biological units, and a monetized benefits 
analysis in which dollar values are applied to quantified physical or 
biological units. The dollar values in a social benefits analysis are 
based on the principle of willingness-to-pay (WTP), which captures 
monetary benefits by measuring what individuals are willing to forgo in 
order to enjoy a particular benefit. Willingness-to-pay for nonuse 
values can be measured using benefits transfer or a stated preference 
survey.
    (y) Social costs means costs estimated from the viewpoint of 
society, rather than individual stakeholders. Social cost represents the 
total burden imposed on the economy; it is the sum of all opportunity 
costs incurred associated with taking actions. These opportunity costs 
consist of the value lost to society of all the goods and services that 
will not be produced and consumed as a facility complies with permit 
requirements, and society reallocates resources away from other 
production activities and towards minimizing adverse environmental 
impacts.



Sec. 125.93  [Reserved]



Sec. 125.94  As an owner or operator of an existing facility, 
what must I do to comply with this subpart?

    (a) Applicable Best Technology Available for Minimizing Adverse 
Environmental Impact (BTA) standards. (1) On or after October 14, 2014, 
the owner or operator of an existing facility with a cumulative design 
intake flow (DIF) greater than 2 mgd is subject to the BTA (best 
technology available) standards for impingement mortality under 
paragraph (c) of this section, and entrainment under paragraph (d) of 
this section including any measures to protect Federally-listed 
threatened and endangered species and designated critical habitat 
established under paragraph (g) of this section.
    (2) Prior to October 14, 2014, the owner or operator of an existing 
facility with a cumulative design intake flow (DIF) greater than 2 mgd 
is subject to site-specific impingement mortality and entrainment 
requirements as determined by the Director on a case-by-case Best 
Professional Judgment basis. The Director's BTA determination may be 
based on consideration of some or all of the factors at Sec. 
125.98(f)(2) and (3) and the requirements of Sec. 125.94(c). If the 
Director requires additional information to make the decision on what 
BTA requirements to include in the applicant's permit for impingement 
mortality and entrainment, the Director should consider whether to 
require any of the information at 40 CFR 122.21(r).
    (3) The owner or operator of a new unit is subject to the 
impingement mortality and entrainment standards under paragraph (e) of 
this section for all cooling water intake flows used by the new unit. 
The remainder of the existing facility is subject to the impingement 
mortality standard under paragraph (c) of this section, and the 
entrainment standard under paragraph (d) of this section. The entire 
existing facility including any new units is subject to any measures to 
protect Federally-listed threatened and endangered species and 
designated critical habitat established under paragraph (g) of this 
section.
    (b) Compliance with BTA standards. (1) Aligning compliance deadlines 
for impingement mortality and entrainment requirements. After issuance 
of a final permit that establishes the entrainment requirements under 
Sec. 125.94(d), the owner or operator of an existing facility must 
comply with the impingement mortality standard in Sec. 125.94(c) as 
soon as practicable. The Director

[[Page 407]]

may establish interim compliance milestones in the permit.
    (2) After issuance of a final permit establishing the entrainment 
requirements under Sec. 125.94(d), the owner or operator of an existing 
facility must comply with the entrainment standard as soon as 
practicable, based on a schedule of requirements established by the 
Director. The Director may establish interim compliance milestones in 
the permit.
    (3) The owner or operator of a new unit at an existing facility must 
comply with the BTA standards at Sec. 125.94(e) with respect to the new 
unit upon commencement of the new unit's operation.
    (c) BTA Standards for Impingement Mortality. The owner or operator 
of an existing facility must comply with one of the alternatives in 
paragraphs (c)(1) through (7) of this section, except as provided in 
paragraphs (c)(11) or (12) of this section, when approved by the 
Director. In addition, a facility may also be subject to the 
requirements of paragraphs (c)(8), (c)(9), or (g) of this section if the 
Director requires such additional measures.
    (1) Closed-cycle recirculating system. A facility must operate a 
closed-cycle recirculating system as defined at Sec. 125.92(c). In 
addition, you must monitor the actual intake flows at a minimum 
frequency of daily. The monitoring must be representative of normal 
operating conditions, and must include measuring cooling water 
withdrawals, make-up water, and blow down volume. In lieu of daily 
intake flow monitoring, you may monitor your cycles of concentration at 
a minimum frequency of daily; or
    (2) 0.5 Feet Per Second Through-Screen Design Velocity. A facility 
must operate a cooling water intake structure that has a maximum design 
through-screen intake velocity of 0.5 feet per second. The owner or 
operator of the facility must submit information to the Director that 
demonstrates that the maximum design intake velocity as water passes 
through the structural components of a screen measured perpendicular to 
the screen mesh does not exceed 0.5 feet per second. The maximum 
velocity must be achieved under all conditions, including during minimum 
ambient source water surface elevations (based on BPJ using hydrological 
data) and during periods of maximum head loss across the screens or 
other devices during normal operation of the intake structure; or
    (3) 0.5 Feet Per Second Through-Screen Actual Velocity. A facility 
must operate a cooling water intake structure that has a maximum 
through-screen intake velocity of 0.5 feet per second. The owner or 
operator of the facility must submit information to the Director that 
demonstrates that the maximum intake velocity as water passes through 
the structural components of a screen measured perpendicular to the 
screen mesh does not exceed 0.5 feet per second. The maximum velocity 
must be achieved under all conditions, including during minimum ambient 
source water surface elevations (based on best professional judgment 
using hydrological data) and during periods of maximum head loss across 
the screens or other devices during normal operation of the intake 
structure. The Director may authorize the owner or operator of the 
facility to exceed the 0.5 fps velocity at an intake for brief periods 
for the purpose of maintaining the cooling water intake system, such as 
backwashing the screen face. If the intake does not have a screen, the 
maximum intake velocity perpendicular to the opening of the intake must 
not exceed 0.5 feet per second during minimum ambient source water 
surface elevations. In addition, you must monitor the velocity at the 
screen at a minimum frequency of daily. In lieu of velocity monitoring 
at the screen face, you may calculate the through-screen velocity using 
water flow, water depth, and the screen open areas; or
    (4) Existing offshore velocity cap. A facility must operate an 
existing offshore velocity cap as defined at Sec. 125.92(v) that was 
installed on or before October 14, 2014. Offshore velocity caps 
installed after October 14, 2014 must make either a demonstration under 
paragraph (c)(6) of this section or meet the performance standard under 
paragraph (c)(7) of this section. In addition, you must monitor your 
intake flow at a minimum frequency of daily; or
    (5) Modified traveling screens. A facility must operate a modified 
traveling

[[Page 408]]

screen that the Director determines meets the definition at Sec. 
125.92(s) and that, after review of the information required in the 
impingement technology performance optimization study at 40 CFR 
122.21(r)(6)(i), the Director determines is the best technology 
available for impingement reduction at the site. As the basis for the 
Director's determination, the owner or operator of the facility must 
demonstrate the technology is or will be optimized to minimize 
impingement mortality of all non-fragile species. The Director must 
include verifiable and enforceable permit conditions that ensure the 
technology will perform as demonstrated; or
    (6) Systems of technologies as the BTA for impingement mortality. A 
facility must operate a system of technologies, management practices, 
and operational measures, that, after review of the information required 
in the impingement technology performance optimization study at 40 CFR 
122.21(r)(6)(ii), the Director determines is the best technology 
available for impingement reduction at your cooling water intake 
structures. As the basis for the Director's determination, the owner or 
operator of the facility must demonstrate the system of technology has 
been optimized to minimize impingement mortality of all non-fragile 
species. In addition, the Director's decision will be informed by 
comparing the impingement mortality performance data under 40 CFR 
122.21(r)(6)(ii)(D) to the impingement mortality performance standard 
that would otherwise apply under paragraph (c)(7) of this section. The 
Director must include verifiable and enforceable permit conditions that 
ensure the system of technologies will perform as demonstrated; or
    (7) Impingement mortality performance standard. A facility must 
achieve a 12-month impingement mortality performance standard of all 
life stages of fish and shellfish of no more than 24 percent mortality, 
including latent mortality, for all non-fragile species together that 
are collected or retained in a sieve with maximum opening dimension of 
0.56 inches and kept for a holding period of 18 to 96 hours. The 
Director may, however, prescribe an alternative holding period. You must 
conduct biological monitoring at a minimum frequency of monthly to 
demonstrate your impingement mortality performance. Each month, you must 
use all of the monitoring data collected during the previous 12 months 
to calculate the 12-month survival percentage. The 12-month impingement 
mortality performance standard is the total number of fish killed 
divided by the total number of fish impinged over the course of the 
entire 12 months. The owner or operator of the facility must choose 
whether to demonstrate compliance with this requirement for the entire 
facility, or for each individual cooling water intake structure for 
which this paragraph (c)(7) is the selected impingement mortality 
requirement.
    (8) Additional measures for shellfish. The owner or operator must 
comply with any additional measures, such as seasonal deployment of 
barrier nets, established by the Director to protect shellfish.
    (9) Additional measures for other species. The owner or operator 
must comply with any additional measures, established by the Director, 
to protect fragile species.
    (10) Reuse of other water for cooling purposes. This impingement 
mortality standard does not apply to that portion of cooling water that 
is process water, gray water, waste water, reclaimed water, or other 
waters reused as cooling water in lieu of water obtained by marine, 
estuarine, or freshwater intakes.
    (11) De minimis rate of impingement. In limited circumstances, rates 
of impingement may be so low at a facility that additional impingement 
controls may not be justified. The Director, based on review of site-
specific data submitted under 40 CFR 122.21(r), may conclude that the 
documented rate of impingement at the cooling water intake is so low 
that no additional controls are warranted. For threatened or endangered 
species, all unauthorized take is prohibited by the Endangered Species 
Act of 1973 (16 U.S.C. 1531 et seq.). Notice of a determination that no 
additional impingement controls are warranted must be included in the 
draft or proposed permit and the Director's response to all comments on 
this

[[Page 409]]

determination must be included in the record for the final permit.
    (12) Low capacity utilization power generating units. If an existing 
facility has a cooling water intake structure used for one or more 
existing electric generating units, each with an annual average capacity 
utilization rate of less than 8 percent averaged over a 24-month block 
contiguous period, the owner or operator may request the Director 
consider less stringent requirements for impingement mortality for that 
cooling water intake structure. The Director may, based on review of 
site-specific data concerning cooling water system data under 40 CFR 
122.21(r)(5), establish the BTA standards for impingement mortality for 
that cooling water intake structure that are less stringent than 
paragraphs (c)(1) through (7) of this section.
    (d) BTA standards for entrainment for existing facilities. The 
Director must establish BTA standards for entrainment for each intake on 
a site-specific basis. These standards must reflect the Director's 
determination of the maximum reduction in entrainment warranted after 
consideration of the relevant factors as specified in Sec. 125.98. The 
Director may also require periodic reporting on your progress towards 
installation and operation of site-specific entrainment controls. These 
reports may include updates on planning, design, and construction or 
other appropriate topics as required by the Director. If the Director 
determines that the site-specific BTA standard for entrainment under 
this paragraph requires performance equivalent to a closed-cycle 
recirculating system as defined at Sec. 125.92(c), then under Sec. 
125.94(c)(1) your facility will comply with the impingement mortality 
standard for that intake.
    (e) BTA standards for impingement mortality and entrainment for new 
units at existing facilities. The owner or operator of a new unit at an 
existing facility must achieve the impingement mortality and entrainment 
standards provided in either paragraph (e)(1) or (2) of this section, 
except as provided in paragraph (e)(4) of this section, for each cooling 
water intake structure used to provide cooling water to the new unit.
    (1) Requirements for new units. The owner or operator of the 
facility must reduce the design intake flow for the new unit, at a 
minimum, to a level commensurate with that which can be attained by the 
use of a closed-cycle recirculating system for the same level of cooling 
for the new unit.
    (2) Alternative requirements for new units. The owner or operator of 
a new unit at an existing facility must demonstrate to the Director that 
the technologies and operational measures employed will reduce the level 
of adverse environmental impact from any cooling water intake structure 
used to supply cooling water to the new unit to a comparable level to 
that which would be achieved under Sec. 125.94(e)(1). This 
demonstration must include a showing that the entrainment reduction is 
equivalent to 90 percent or greater of the reduction that could be 
achieved through compliance with Sec. 125.94(e)(1). In addition this 
demonstration must include a showing that the impacts to fish and 
shellfish, including important forage and predator species, within the 
watershed will be comparable to those which would result under the 
requirements of Sec. 125.94(e)(1).
    (3) This standard does not apply to:
    (i) Process water, gray water, waste water, reclaimed water, or 
other waters reused as cooling water in lieu of water obtained by 
marine, estuarine, or freshwater intakes;
    (ii) Cooling water used by manufacturing facilities for contact 
cooling purposes;
    (iii) Portions of those water withdrawals for auxiliary plant 
cooling uses comprising less than two mgd of the facility's flow; and
    (iv) Any quantity of emergency back-up water flows.
    (4) The owner or operator of a facility must comply with any 
alternative requirements established by the Director pursuant to Sec. 
125.98(b)(7).
    (5) For cooling water flows excluded by paragraph (e)(3) of this 
section, the Director may establish additional BTA standards for 
impingement mortality and entrainment on a site-specific basis.

[[Page 410]]

    (f) Nuclear facilities. If the owner or operator of a nuclear 
facility demonstrates to the Director, upon the Director's consultation 
with the Nuclear Regulatory Commission, the Department of Energy, or the 
Naval Nuclear Propulsion Program, that compliance with this subpart 
would result in a conflict with a safety requirement established by the 
Commission, the Department, or the Program, the Director must make a 
site-specific determination of best technology available for minimizing 
adverse environmental impact that would not result in a conflict with 
the Commission's, the Department's, or the Program's safety requirement.
    (g) Additional measures to protect Federally-listed threatened and 
endangered species and designated critical habitat. The Director may 
establish in the permit additional control measures, monitoring 
requirements, and reporting requirements that are designed to minimize 
incidental take, reduce or remove more than minor detrimental effects to 
Federally-listed species and designated critical habitat, or avoid 
jeopardizing Federally-listed species or destroying or adversely 
modifying designated critical habitat (e.g., prey base). Such control 
measures, monitoring requirements, and reporting requirements may 
include measures or requirements identified by an appropriate Field 
Office of the U.S. Fish and Wildlife Service and/or Regional Office of 
the National Marine Fisheries Service during the 60 day review period 
pursuant to Sec. 125.98(h) or the public notice and comment period 
pursuant to 40 CFR 124.10. Where established in the permit by the 
Director, the owner or operator must implement any such requirements.
    (h) Interim BTA requirements. An owner or operator of a facility may 
be subject to interim BTA requirements established by the Director in 
the permit on a site-specific basis.
    (i) More stringent standards. The Director must establish more 
stringent requirements as best technology available for minimizing 
adverse environmental impact if the Director determines that compliance 
with the applicable requirements of this section would not meet the 
requirements of applicable State or Tribal law, including compliance 
with applicable water quality standards (including designated uses, 
criteria, and antidegradation requirements).
    (j) The owner or operator of a facility subject to this subpart 
must:
    (1) Submit and retain permit application and supporting information 
as specified in Sec. 125.95;
    (2) Conduct compliance monitoring as specified in Sec. 125.96; and
    (3) Report information and data and keep records as specified in 
Sec. 125.97.



Sec. 125.95  Permit application and supporting information requirements.

    (a) Permit application submittal timeframe for existing facilities. 
(1) The owner or operator of a facility subject to this subpart whose 
currently effective permit expires after July 14, 2018, must submit to 
the Director the information required in the applicable provisions of 40 
CFR 122.21(r) when applying for a subsequent permit (consistent with the 
owner or operator's duty to reapply pursuant to 40 CFR 122.21(d)).
    (2) The owner or operator of a facility subject to this subpart 
whose currently effective permit expires prior to or on July 14, 2018, 
may request the Director to establish an alternate schedule for the 
submission of the information required in 40 CFR 122.21(r) when applying 
for a subsequent permit (consistent with the owner or operator's duty to 
reapply pursuant to 40 CFR 122.21(d)). If the owner or operator of the 
facility demonstrates that it could not develop the required information 
by the applicable date for submission, the Director must establish an 
alternate schedule for submission of the required information.
    (3) The Director may waive some or all of the information 
requirements of 40 CFR 122.21(r) if the intake is located in a manmade 
lake or reservoir and the fisheries are stocked and managed by a State 
or Federal natural resources agency or the equivalent. If the manmade 
lake or reservoir contains Federally-listed threatened and endangered 
species, or is designated critical habitat, such a waiver shall not be 
granted.
    (b) Permit application submittal timeframe for new units. For the 
owner or operator of any new unit at an existing facility subject to 
this subpart:

[[Page 411]]

    (1) You must submit the information required in 40 CFR 122.21(r) for 
the new unit to the Director no later than 180 days before the planned 
commencement of cooling water withdrawals for the operation of the new 
unit. If you have already submitted the required information in your 
previous permit application, you may choose to submit an update to the 
required information.
    (2) The owner or operator is encouraged to submit their permit 
applications well in advance of the 180 day requirement to avoid delay.
    (c) Permit applications. After the initial submission of the 40 CFR 
122.21(r) permit application studies after October 14, 2014, the owner 
or operator of a facility may, in subsequent permit applications, 
request to reduce the information required, if conditions at the 
facility and in the waterbody remain substantially unchanged since the 
previous application so long as the relevant previously submitted 
information remains representative of current source water, intake 
structure, cooling water system, and operating conditions. Any habitat 
designated as critical or species listed as threatened or endangered 
after issuance of the current permit whose range of habitat or 
designated critical habit includes waters where a facility intake is 
located constitutes potential for a substantial change that must be 
addressed by the owner/operator in subsequent permit applications, 
unless the facility received an exemption pursuant to 16 U.S.C. 1536(o) 
or a permit pursuant to 16 U.S.C. 1539(a) or there is no reasonable 
expectation of take. The owner or operator of a facility must submit its 
request for reduced cooling water intake structure and waterbody 
application information to the Director at least two years and six 
months prior to the expiration of its NPDES permit. The owner or 
operator's request must identify each element in this subsection that it 
determines has not substantially changed since the previous permit 
application and the basis for the determination. The Director has the 
discretion to accept or reject any part of the request.
    (d) The Director has the discretion to request additional 
information to supplement the permit application, including a request to 
inspect a facility.
    (e) Permit application records. The owner or operator of a facility 
must keep records of all submissions that are part of its permit 
application until the subsequent permit is issued to document compliance 
with the requirements of this section. If the Director approves a 
request for reduced permit application studies under Sec. 125.95(a) or 
(c) or Sec. 125.98(g), the owner or operator of a facility must keep 
records of all submissions that are part of the previous permit 
application until the subsequent permit is issued.
    (f) In addition, in developing its permit application, the owner or 
operator of an existing facility or new unit at an existing facility 
must, based on readily available information at the time of the permit 
application, instead of the information required at Sec. 
122.21(r)(4)(vi) of this chapter identify all Federally-listed 
threatened and endangered species and/or designated critical habitat 
that are or may be present in the action area.
    (g) Certification. The owner or operator of a facility must certify 
that its permit application is true, accurate and complete pursuant to 
Sec. 122.22(d) of this chapter.



Sec. 125.96  Monitoring requirements.

    (a) Monitoring requirements for impingement mortality for existing 
facilities. The Director may establish monitoring requirements in 
addition to those specified at Sec. 125.94(c), including, for example, 
biological monitoring, intake velocity and flow measurements. If the 
Director establishes such monitoring, the specific protocols will be 
determined by the Director.
    (b) Monitoring requirements for entrainment for existing facilities. 
Monitoring requirements for entrainment will be determined by the 
Director on a site-specific basis, as appropriate, to meet requirements 
under Sec. 125.94(d).
    (c) Additional monitoring requirements for existing facilities. The 
Director may require additional monitoring for impingement or 
entrainment including, but not limited to, the following:
    (1) The Director may require additional monitoring if there are 
changes in operating conditions at the facility

[[Page 412]]

or in the source waterbody that warrant a re-examination of the 
operational conditions identified at 40 CFR 122.21(r).
    (2) The Director may require additional monitoring for species not 
subject to the BTA requirements for impingement mortality at Sec. 
125.95(c). Such monitoring requirements will be determined by the 
Director on a site-specific basis.
    (d) Monitoring requirements for new units at existing facilities. 
Monitoring is required to demonstrate compliance with the requirements 
of Sec. 125.94(e).
    (1) The Director may establish monitoring requirements for 
impingement, impingement mortality, and entrainment of the commercial, 
recreational, and forage base fish and shellfish species identified in 
the Source Water Baseline Biological Characterization data required by 
40 CFR 122.21(r)(4). Monitoring methods used must be consistent with 
those used for the Source Water Baseline Biological Characterization at 
40 CFR 122.21(r)(4). If the Director establishes such monitoring 
requirements, the frequency of monitoring and specific protocols will be 
determined by the Director.
    (2) If your facility is subject to the requirements of Sec. 
125.94(e)(1) or (2), the frequency of flow monitoring and velocity 
monitoring must be daily and must be representative of normal operating 
conditions. Flow monitoring must include measuring cooling water 
withdrawals, make-up water, and blowdown volume. The Director may 
require additional monitoring necessary to demonstrate compliance with 
Sec. 125.94(e).
    (3) If your facility is subject to the requirements of Sec. 
125.94(e)(2), you must monitor to demonstrate achievement of reductions 
commensurate with a closed-cycle recirculating system. You must monitor 
entrainable organisms at a proximity to the intake that is 
representative of the entrainable organisms in the absence of the intake 
structure. You must also monitor the latent entrainment mortality in 
front of the intake structure. Mortality after passing the cooling water 
intake structure must be counted as 100 percent mortality unless you 
have demonstrated to the approval of the Director that the mortality for 
each species is less than 100 percent. Monitoring must be representative 
of the cooling water intake when the structure is in operation. In 
addition, sufficient samples must be collected to allow for calculation 
of annual average entrainment levels of all life stages of fish and 
shellfish. Specific monitoring protocols and frequency of monitoring 
will be determined by the Director. You must follow the monitoring 
frequencies identified by the Director for at least two years after the 
initial permit issuance. After that time, the Director may approve a 
request for less frequent monitoring in the remaining years of the 
permit term and when a subsequent permit is reissued. The monitoring 
must measure the total count of entrainable organisms or density of 
organisms, unless the Director approves of a different metric for such 
measurements. In addition, you must monitor the AIF for each intake. The 
AIF must be measured at the same time as the samples of entrainable 
organisms are collected. The Director may require additional monitoring 
necessary to demonstrate compliance with Sec. 125.94(e).
    (4) The Director may require additional monitoring for impingement 
or entrainment at the cooling water intake structure used by a new unit 
including, but not limited to, the following:
    (i) The Director may require additional monitoring if there are 
changes in operating conditions at the facility or in the source 
waterbody that warrant a re-examination of the operational conditions 
identified at 40 CFR 122.21(r).
    (ii) The Director may require additional monitoring for species not 
subject to the BTA requirements for impingement mortality at Sec. 
125.95(c). Such monitoring requirements will be determined by the 
Director on a site-specific basis.
    (e) Visual or remote inspections. You must either conduct visual 
inspections or employ remote monitoring devices during the period the 
cooling water intake structure is in operation. You must conduct such 
inspections at least weekly to ensure that any technologies operated to 
comply with Sec. 125.94 are maintained and operated to function as

[[Page 413]]

designed including those installed to protect Federally-listed 
threatened or endangered species or designated critical habitat. The 
Director may establish alternative procedures if this requirement is not 
feasible (e.g., an offshore intake, velocity cap, or during periods of 
inclement weather).
    (f) Request for reduced monitoring. For facilities that are subject 
to Sec. 125.94(c)(7) and where the facility's cooling water intake 
structure does not directly or indirectly affect Federally-listed 
threatened and endangered species, or designated critical habitat, the 
owner or operator of the facility may request the Director to reduce 
monitoring requirements after the first full permit term in which these 
monitoring requirements are implemented, on the condition that the 
results of the monitoring to date demonstrate that the owner or operator 
of the facility has consistently operated the intake as designed and is 
meeting the requirements of Sec. 125.94(c).
    (g) Additional monitoring related to Federally-listed threatened and 
endangered species and designated critical habitat at existing 
facilities. Where the Director requires additional measures to protect 
Federally-listed threatened or endangered species or designated critical 
habitat pursuant to Sec. 125.94(g), the Director shall require 
monitoring associated with those measures.



Sec. 125.97  Other permit reporting and recordkeeping requirements.

    The owner or operator of an existing facility subject to this 
subpart is required to submit to the Director the following information:
    (a) Monitoring reports. Discharge Monitoring Reports (DMRs) (or 
equivalent State reports) and results of all monitoring, demonstrations, 
and other information required by the permit sufficient to determine 
compliance with the permit conditions and requirements established under 
Sec. 125.94.
    (b) Status reports. Any reports required by the Director under Sec. 
125.94.
    (c) Annual certification statement and report. An annual 
certification statement signed by the responsible corporate officer as 
defined in Sec. 122.22 of this chapter subject to the following:
    (1) If the information contained in the previous year's annual 
certification is still pertinent, you may simply state as such in a 
letter to the Director and the letter, along with any applicable data 
submission requirements specified in this section shall constitute the 
annual certification.
    (2) If you have substantially modified operation of any unit at your 
facility that impacts cooling water withdrawals or operation of your 
cooling water intake structures, you must provide a summary of those 
changes in the report. In addition, you must submit revisions to the 
information required at Sec. 122.21(r) of this chapter in your next 
permit application.
    (d) Permit reporting records retention. Records of all submissions 
that are part of the permit reporting requirements of this section must 
be retained until the subsequent permit is issued. In addition, the 
Director may require supplemental recordkeeping such as compliance 
monitoring under Sec. 125.96, supplemental data collection under 40 CFR 
122.21, additional monitoring or data collection under Sec. 125.95.
    (e) Reporting. The Director has the discretion to require additional 
reporting when necessary to establish permit compliance and may provide 
for periodic inspection of the facility. The Director may require 
additional reporting including but not limited to the records required 
under Sec. 125.97(d).
    (f) Records of Director's Determination of BTA for Entrainment. All 
records supporting the Director's Determination of BTA for Entrainment 
under Sec. 125.98(f) or (g) must be retained until such time as the 
Director revises the Determination of BTA for Entrainment in the permit.
    (g) Additional reporting requirements related to Federally-listed 
threatened and endangered species or designated critical habitat. Where 
the Director requires additional measures to protect Federally-listed 
threatened or endangered species or critical habitat pursuant to Sec. 
125.94(g), the Director shall require reporting associated with those 
measures.



Sec. 125.98  Director requirements.

    (a) Permit application. The Director must review the materials 
submitted

[[Page 414]]

by the applicant under 40 CFR 122.21(r) for completeness pursuant to 40 
CFR 122.21(e) at the time of initial permit application and any 
application for a subsequent permit.
    (b) Permitting requirements. Section 316(b) requirements are 
implemented through an NPDES permit. Based on the information submitted 
in the permit application, the Director must determine the requirements 
and conditions to include in the permit.
    (1) Such permits, including permits with alternative requirements 
under paragraph (b)(7) of this section, must include the following 
language as a permit condition: ``Nothing in this permit authorizes take 
for the purposes of a facility's compliance with the Endangered Species 
Act.''
    (2) In the case of any permit issued after July 14, 2018, at a 
minimum, the permit must include conditions to implement and ensure 
compliance with the impingement mortality standard at Sec. 125.94(c) 
and the entrainment standard at Sec. 125.94(d), including any measures 
to protect Federally-listed threatened and endangered species and 
designated critical habitat required by the Director. In addition, the 
permit must include conditions, management practices and operational 
measures necessary to ensure proper operation of any technology used to 
comply with the impingement mortality standard at Sec. 125.94(c) and 
the entrainment standard at Sec. 125.94(d). Pursuant to Sec. 
125.94(g), the permit may include additional control measures, 
monitoring requirements, and reporting requirements that are designed to 
minimize incidental take, reduce or remove more than minor detrimental 
effects to Federally-listed species and designated critical habitat, or 
avoid jeopardizing Federally-listed species or destroying or adversely 
modifying designated critical habitat (e.g. prey base). Such control 
measures, monitoring requirements, and reporting requirements may 
include measures or requirements identified by the U.S. Fish and 
Wildlife Service and/or the National Marine Fisheries Service during the 
60 day review period pursuant to Sec. 125.98(h) or the public notice 
and comment period pursuant to 40 CFR 124.10. The Director may include 
additional permit requirements if:
    (i) Based on information submitted to the Director by any fishery 
management agency or other relevant information, there are migratory or 
sport or commercial species subject to entrainment that may be directly 
or indirectly affected by the cooling water intake structure; or
    (ii) It is determined by the Director, based on information 
submitted by any fishery management agencies or other relevant 
information, that operation of the facility, after meeting the 
entrainment standard of this section, would still result in undesirable 
cumulative stressors to Federally-listed and proposed, threatened and 
endangered species, and designated and proposed critical habitat.
    (3) At a minimum, the permit must require the permittee to monitor 
as required at Sec. Sec. 125.94 and 125.96.
    (4) At a minimum, the permit must require the permittee to report 
and keep the records specified at Sec. 125.97.
    (5) After October 14, 2014, in the case of any permit issued before 
July 14, 2018 for which the Director, pursuant to Sec. 125.95(a)(2), 
has established an alternate schedule for submission of the information 
required by 40 CFR 122.21(r), the Director may include permit conditions 
to ensure that, for any subsequent permit, the Director will have all 
the information required by 40 CFR 122.21(r) necessary to establish 
impingement mortality and entrainment BTA requirements under Sec. 
125.94(c) and (d). In addition, the Director must establish interim BTA 
requirements in the permit based on the Director's best professional 
judgment on a site-specific basis in accordance with Sec. 125.90(b) and 
40 CFR 401.14.
    (6) In the case of any permit issued after October 14, 2014, and 
applied for before October 14, 2014, the Director may include permit 
conditions to ensure that the Director will have all the information 
under 40 CFR 122.21(r) necessary to establish impingement mortality and 
entrainment BTA requirements under Sec. 125.94(c) and (d) for the 
subsequent permit. The Director must establish interim BTA requirements 
in the permit on a site-specific basis

[[Page 415]]

based on the Director's best professional judgment in accordance with 
Sec. 125.90(b) and 40 CFR 401.14.
    (7) For new units at existing facilities, the Director may establish 
alternative requirements if the data specific to the facility indicate 
that compliance with the requirements of Sec. 125.94(e)(1) or (2) for 
each new unit would result in compliance costs wholly out of proportion 
to the costs EPA considered in establishing the requirements at issue, 
or would result in significant adverse impacts on local air quality, 
significant adverse impacts on local water resources other than 
impingement or entrainment, or significant adverse impacts on local 
energy markets:
    (i) The alternative requirements must achieve a level of performance 
as close as practicable to the requirements of Sec. 125.94(e)(1);
    (ii) The alternative requirements must ensure compliance with these 
regulations, other provisions of the Clean Water Act, and State and 
Tribal law;
    (iii) The burden is on the owner or operator of the facility 
requesting the alternative requirement to demonstrate that alternative 
requirements should be authorized for the new unit.
    (8) The Director may require additional measures such as seasonal 
deployment of barrier nets, to protect shellfish.
    (c) Compliance schedule. When the Director establishes a schedule of 
requirements under Sec. 125.94(b), the schedule must provide for 
compliance with Sec. 125.94(c) and (d) as soon as practicable. When 
establishing a schedule for electric power generating facilities, the 
Director should consider measures to maintain adequate energy 
reliability and necessary grid reserve capacity during any facility 
outage. These may include establishing a staggered schedule for multiple 
facilities serving the same localities. The Director may confer with 
independent system operators and state public utility regulatory 
agencies when establishing a schedule for electric power generating 
facilities. The Director may determine that extenuating circumstances 
(e.g., lengthy scheduled outages, future production schedules) warrant 
establishing a different compliance date for any manufacturing facility.
    (d) Supplemental Technologies and Monitoring. The Director may 
require additional technologies for protection of fragile species, and 
may require additional monitoring of species of fish and shellfish not 
already required under Sec. 125.95(c). The Director may consider data 
submitted by other interested parties. The Director may also require 
additional study and monitoring if a threatened or endangered species 
has been identified in the vicinity of the intake.
    (e) Impingement technology performance optimization study. The owner 
or operator of a facility that chooses to comply with Sec. 125.94(c)(5) 
or (6) must demonstrate in its impingement technology performance 
optimization study that the operation of its impingement reduction 
technology has been optimized to minimize impingement mortality of non-
fragile species. The Director may request further data collection and 
information as part of the impingement technology performance 
optimization study, including extending the study period beyond two 
years. The Director may also consider previously collected biological 
data and performance reviews as part of the study. The Director must 
include in the permit verifiable and enforceable permit conditions that 
ensure the modified traveling screens or other systems of technologies 
will perform as demonstrated. The Director may waive all or part of the 
impingement technology performance optimization study at 40 
CFR122.21(r)(6) after the first permit cycle wherein the permittee is 
deemed in compliance with Sec. 125.94(c).
    (f) Site-specific entrainment requirements. The Director must 
establish site-specific requirements for entrainment after reviewing the 
information submitted under 40 CFR 122.21(r) and Sec. 125.95. These 
entrainment requirements must reflect the Director's determination of 
the maximum reduction in entrainment warranted after consideration of 
factors relevant for determining the best technology available for 
minimizing adverse environmental impact at each facility. These 
entrainment requirements may also reflect

[[Page 416]]

any control measures to reduce entrainment of Federally-listed 
threatened and endangered species and designated critical habitat (e.g. 
prey base). The Director may reject an otherwise available technology as 
a basis for entrainment requirements if the Director determines there 
are unacceptable adverse impacts including impingement, entrainment, or 
other adverse effects to Federally-listed threatened or endangered 
species or designated critical habitat. Prior to any permit reissuance 
after July 14, 2018, the Director must review the performance of the 
facility's installed entrainment technology to determine whether it 
continues to meet the requirements of Sec. 125.94(d).
    (1) The Director must provide a written explanation of the proposed 
entrainment determination in the fact sheet or statement of basis for 
the proposed permit under 40 CFR 124.7 or 124.8. The written explanation 
must describe why the Director has rejected any entrainment control 
technologies or measures that perform better than the selected 
technologies or measures, and must reflect consideration of all 
reasonable attempts to mitigate any adverse impacts of otherwise 
available better performing entrainment technologies.
    (2) The proposed determination in the fact sheet or statement of 
basis must be based on consideration of any additional information 
required by the Director at Sec. 125.98(i) and the following factors 
listed below. The weight given to each factor is within the Director's 
discretion based upon the circumstances of each facility.
    (i) Numbers and types of organisms entrained, including, 
specifically, the numbers and species (or lowest taxonomic 
classification possible) of Federally-listed, threatened and endangered 
species, and designated critical habitat (e.g., prey base);
    (ii) Impact of changes in particulate emissions or other pollutants 
associated with entrainment technologies;
    (iii) Land availability inasmuch as it relates to the feasibility of 
entrainment technology;
    (iv) Remaining useful plant life; and
    (v) Quantified and qualitative social benefits and costs of 
available entrainment technologies when such information on both 
benefits and costs is of sufficient rigor to make a decision.
    (3) The proposed determination in the fact sheet or statement of 
basis may be based on consideration of the following factors to the 
extent the applicant submitted information under 40 CFR 122.21(r) on 
these factors:
    (i) Entrainment impacts on the waterbody;
    (ii) Thermal discharge impacts;
    (iii) Credit for reductions in flow associated with the retirement 
of units occurring within the ten years preceding October 14, 2014;
    (iv) Impacts on the reliability of energy delivery within the 
immediate area;
    (v) Impacts on water consumption; and
    (vi) Availability of process water, gray water, waste water, 
reclaimed water, or other waters of appropriate quantity and quality for 
reuse as cooling water.
    (4) If all technologies considered have social costs not justified 
by the social benefits, or have unacceptable adverse impacts that cannot 
be mitigated, the Director may determine that no additional control 
requirements are necessary beyond what the facility is already doing. 
The Director may reject an otherwise available technology as a BTA 
standard for entrainment if the social costs are not justified by the 
social benefits.
    (g) Ongoing permitting proceedings. In the case of permit 
proceedings begun prior to October 14, 2014 whenever the Director has 
determined that the information already submitted by the owner or 
operator of the facility is sufficient, the Director may proceed with a 
determination of BTA standards for impingement mortality and entrainment 
without requiring the owner or operator of the facility to submit the 
information required in 40 CFR 122.21(r). The Director's BTA 
determination may be based on some or all of the factors in paragraphs 
(f)(2) and (3) of this section and the BTA standards for impingement 
mortality at Sec. 125.95(c). In making the decision on whether to 
require additional information from the applicant, and what BTA 
requirements to include in the applicant's permit for

[[Page 417]]

impingement mortality and site-specific entrainment, the Director should 
consider whether any of the information at 40 CFR 122.21(r) is 
necessary.
    (h) The Director must transmit all permit applications for 
facilities subject to this subpart to the appropriate Field Office of 
the U.S. Fish and Wildlife Service and/or Regional Office of the 
National Marine Fisheries Service upon receipt for a 60 day review prior 
to public notice of the draft or proposed permit. The Director shall 
provide the public notice and an opportunity to comment as required 
under 40 CFR 124.10 and must submit a copy of the fact sheet or 
statement of basis (for EPA-issued permits), the permit application (if 
any) and the draft permit (if any) to the appropriate Field Office of 
the. Fish and Wildlife Service and/or Regional Office of the National 
Marine Fisheries Service. This includes notice of specific cooling water 
intake structure requirements at Sec. 124.10(d)(1)(ix) of this chapter, 
notice of the draft permit, and any specific information the Director 
has about threatened or endangered species and critical habitat that are 
or may be present in the action area, including any proposed control 
measures and monitoring and reporting requirements for such species and 
habitat.
    (i) Additional information. In implementing the Director's 
responsibilities under the provisions of this subpart, the Director is 
authorized to inspect the facility and to request additional information 
needed by the Director for determining permit conditions and 
requirements, including any additional information from the facility 
recommended by the Services upon review of the permit application under 
paragraph (h) of this section.
    (j) Nothing in this subpart authorizes the take, as defined at 16 
U.S.C. 1532(19), of threatened or endangered species of fish or 
wildlife. Such take is prohibited under the Endangered Species Act 
unless it is exempted pursuant to 16 U.S.C. 1536(o) or permitted 
pursuant to 16 U.S.C. 1539(a). Absent such exemption or permit, any 
facility operating under the authority of this regulation must not take 
threatened or endangered wildlife.
    (k) The Director must submit at least annually to the appropriate 
EPA Regional Office facilities' annual reports submitted pursuant to 
Sec. 125.97(g), for compilation and transmittal to the Services.



Sec. 125.99  [Reserved]

Subpart K [Reserved]

Subpart L--Criteria and Standards for Imposing Conditions for the Disposal 
of Sewage Sludge Under Section 405 of the Act [Reserved]



                   Subpart M_Ocean Discharge Criteria

    Source: 45 FR 65953, Oct. 3, 1980, unless otherwise noted.



Sec. 125.120  Scope and purpose.

    This subpart establishes guidelines for issuance of National 
Pollutant Discharge Elimination System (NPDES) permits for the discharge 
of pollutants from a point source into the territorial seas, the 
contiguous zone, and the oceans.



Sec. 125.121  Definitions.

    (a) Irreparable harm means significant undesirable effects occurring 
after the date of permit issuance which will not be reversed after 
cessation or modification of the discharge.
    (b) Marine environment means that territorial seas, the contiguous 
zone and the oceans.
    (c) Mixing zone means the zone extending from the sea's surface to 
seabed and extending laterally to a distance of 100 meters in all 
directions from the discharge point(s) or to the boundary of the zone of 
initial dilution as calculated by a plume model approved by the 
director, whichever is greater, unless the director determines that the 
more restrictive mixing zone or another definition of the mixing zone is 
more appropriate for a specific discharge.
    (d) No reasonable alternatives means:
    (1) No land-based disposal sites, discharge point(s) within internal 
waters, or approved ocean dumping sites within a reasonable distance of 
the site of the proposed discharge the use of which

[[Page 418]]

would not cause unwarranted economic impacts on the discharger, or, 
notwithstanding the availability of such sites,
    (2) On-site disposal is environmentally preferable to other 
alternative means of disposal after consideration of:
    (i) The relative environmental harm of disposal on-site, in disposal 
sites located on land, from discharge point(s) within internal waters, 
or in approved ocean dumping sites, and
    (ii) The risk to the environment and human safety posed by the 
transportation of the pollutants.
    (e) Unreasonable degradation of the marine environment means: (1) 
Significant adverse changes in ecosystem diversity, productivity and 
stability of the biological community within the area of discharge and 
surrounding biological communities,
    (2) Threat to human health through direct exposure to pollutants or 
through consumption of exposed aquatic organisms, or
    (3) Loss of esthetic, recreational, scientific or economic values 
which is unreasonable in relation to the benefit derived from the 
discharge.



Sec. 125.122  Determination of unreasonable degradation of the marine
environment.

    (a) The director shall determine whether a discharge will cause 
unreasonable degradation of the marine environment based on 
consideration of:
    (1) The quantities, composition and potential for bioaccumulation or 
persistence of the pollutants to be discharged;
    (2) The potential transport of such pollutants by biological, 
physical or chemical processes;
    (3) The composition and vulnerability of the biological communities 
which may be exposed to such pollutants, including the presence of 
unique species or communities of species, the presence of species 
identified as endangered or threatened pursuant to the Endangered 
Species Act, or the presence of those species critical to the structure 
or function of the ecosystem, such as those important for the food 
chain;
    (4) The importance of the receiving water area to the surrounding 
biological community, including the presence of spawning sites, nursery/
forage areas, migratory pathways, or areas necessary for other functions 
or critical stages in the life cycle of an organism.
    (5) The existence of special aquatic sites including, but not 
limited to marine sanctuaries and refuges, parks, national and historic 
monuments, national seashores, wilderness areas and coral reefs;
    (6) The potential impacts on human health through direct and 
indirect pathways;
    (7) Existing or potential recreational and commercial fishing, 
including finfishing and shellfishing;
    (8) Any applicable requirements of an approved Coastal Zone 
Management plan;
    (9) Such other factors relating to the effects of the discharge as 
may be appropriate;
    (10) Marine water quality criteria developed pursuant to section 
304(a)(1).
    (b) Discharges in compliance with section 301(g), 301(h), or 316(a) 
variance requirements or State water quality standards shall be presumed 
not to cause unreasonable degradation of the marine environment, for any 
specific pollutants or conditions specified in the variance or the 
standard.



Sec. 125.123  Permit requirements.

    (a) If the director on the basis of available information including 
that supplied by the applicant pursuant to Sec. 125.124 determines 
prior to permit issuance that the discharge will not cause unreasonable 
degradation of the marine environment after application of any necessary 
conditions specified in Sec. 125.123(d), he may issue an NPDES permit 
containing such conditions.
    (b) If the director, on the basis of available information including 
that supplied by the applicant pursuant to Sec. 125.124 determines 
prior to permit issuance that the discharge will cause unreasonable 
degradation of the marine environment after application of all possible 
permit conditions specified in Sec. 125.123(d), he may not issue an 
NPDES permit which authorizes the discharge of pollutants.
    (c) If the director has insufficient information to determine prior 
to permit

[[Page 419]]

issuance that there will be no unreasonable degradation of the marine 
environment pursuant to Sec. 125.122, there shall be no discharge of 
pollutants into the marine environment unless the director on the basis 
of available information, including that supplied by the applicant 
pursuant to Sec. 125.124 determines that:
    (1) Such discharge will not cause irreparable harm to the marine 
environment during the period in which monitoring is undertaken, and
    (2) There are no reasonable alternatives to the on-site disposal of 
these materials, and
    (3) The discharge will be in compliance with all permit conditions 
established pursuant to paragraph (d) of this section.
    (d) All permits which authorize the discharge of pollutants pursuant 
to paragraph (c) of this section shall:

Subpart N_Requirements Applicable to Cooling Water Intake Structures for 
 New Offshore Oil and Gas Extraction Facilities Under Section 316(b) of 
                                 the Act

    Source: 71 FR 35040, June 16, 2006, unless otherwise noted.



Sec. 125.130  What are the purpose and scope of this subpart?

    (a) This subpart establishes requirements that apply to the 
location, design, construction, and capacity of cooling water intake 
structures at new offshore oil and gas extraction facilities. The 
purpose of these requirements is to establish the best technology 
available for minimizing adverse environmental impact associated with 
the use of cooling water intake structures at these facilities. These 
requirements

[[Page 420]]

are implemented through National Pollutant Discharge Elimination System 
(NPDES) permits issued under section 402 of the Clean Water Act (CWA).
    (b) This subpart implements section 316(b) of the CWA for new 
offshore oil and gas extraction facilities. Section 316(b) of the CWA 
provides that any standard established pursuant to sections 301 or 306 
of the CWA and applicable to a point source shall require that the 
location, design, construction, and capacity of cooling water intake 
structures reflect the best technology available for minimizing adverse 
environmental impact.
    (c) New offshore oil and gas extraction facilities that do not meet 
the threshold requirements regarding amount of water withdrawn or 
percentage of water withdrawn for cooling water purposes in Sec. 
125.131(a) must meet requirements determined by the Director on a case-
by-case, best professional judgement (BPJ) basis.
    (d) Nothing in this subpart shall be construed to preclude or deny 
the right of any State or political subdivision of a State or any 
interstate agency under section 510 of the CWA to adopt or enforce any 
requirement with respect to control or abatement of pollution that is 
more stringent than those required by Federal law.



Sec. 125.131  Who is subject to this subpart?

    (a) This subpart applies to a new offshore oil and gas extraction 
facility if it meets all of the following criteria:
    (1) It is a point source that uses or proposes to use a cooling 
water intake structure;
    (2) It has at least one cooling water intake structure that uses at 
least 25 percent of the water it withdraws for cooling purposes as 
specified in paragraph (c) of this section; and
    (3) It has a design intake flow greater than two (2) million gallons 
per day (MGD).
    (b) Use of a cooling water intake structure includes obtaining 
cooling water by any sort of contract or arrangement with an independent 
supplier (or multiple suppliers) of cooling water if the supplier or 
suppliers withdraw(s) water from waters of the United States. Use of 
cooling water does not include obtaining cooling water from a public 
water system or the use of treated effluent that otherwise would be 
discharged to a water of the U.S.
    (c) The threshold requirement that at least 25 percent of water 
withdrawn be used for cooling purposes must be measured on an average 
monthly basis. A new offshore oil and gas extraction facility meets the 
25 percent cooling water threshold if, based on the new facility's 
design, any monthly average over a year for the percentage of cooling 
water withdrawn is expected to equal or exceed 25 percent of the total 
water withdrawn.
    (d) Neither this subpart nor Subpart I of this part applies to 
seafood processing vessels or offshore liquefied natural gas import 
terminals that are new facilities as defined in 40 CFR 125.83. Seafood 
processing vessels and offshore liquefied natural gas import terminals 
must meet requirements established by the Director on a case-by-case, 
best professional judgment (BPJ) basis.



Sec. 125.132  When must I comply with this subpart?

    You must comply with this subpart when an NPDES permit containing 
requirements consistent with this subpart is issued to you.



Sec. 125.133  What special definitions apply to this subpart?

    In addition to the definitions set forth at 40 CFR 125.83, the 
following special definitions apply to this subpart:
    Cooling water means water used for contact or noncontact cooling, 
including water used for equipment cooling, evaporative cooling tower 
makeup, and dilution of effluent heat content. The intended use of the 
cooling water is to absorb waste heat rejected from the process or 
processes used, or from auxiliary operations on the facility's premises. 
Cooling water that is used in another industrial process either before 
or after it is used for cooling is considered process water rather than 
cooling water for the purposes of calculating the percentage of a new 
offshore oil and gas extraction facility's intake flow that is used for 
cooling purposes in Sec. 125.131(c).

[[Page 421]]

    Fixed facility means a bottom founded offshore oil and gas 
extraction facility permanently attached to the seabed or subsoil of the 
outer continental shelf (e.g., platforms, guyed towers, articulated 
gravity platforms) or a buoyant facility securely and substantially 
moored so that it cannot be moved without a special effort (e.g., 
tension leg platforms, permanently moored semi-submersibles) and which 
is not intended to be moved during the production life of the well. This 
definition does not include mobile offshore drilling units (MODUs) 
(e.g., drill ships, temporarily moored semi-submersibles, jack-ups, 
submersibles, tender-assisted rigs, and drill barges).
    Minimum ambient source water surface elevation means the mean low 
tidal water level for estuaries or oceans. The mean low tidal water 
level is the average height of the low water over at least 19 years.
    New offshore oil and gas extraction facility means any building, 
structure, facility, or installation that: meets the definition of a 
``new facility'' at 40 CFR 125.83; and is regulated by the Offshore or 
Coastal Subcategories of the Oil and Gas Extraction Point Source 
Category Effluent Guidelines in 40 CFR 435.10 or 40 CFR 435.40; but only 
if it commences construction after July 17, 2006.
    Offshore liquefied natural gas (LNG) import terminal means any 
facility located in waters defined in 40 CFR 435.10 or 40 CFR 435.40 
that liquefies, re-gasifies, transfers, or stores liquefied natural gas.
    Sea chest means the underwater compartment or cavity within the 
facility or vessel hull or pontoon through which sea water is drawn in 
(for cooling and other purposes) or discharged.
    Seafood processing vessel means any offshore or nearshore, floating, 
mobile, facility engaged in the processing of fresh, frozen, canned, 
smoked, salted or pickled seafood, seafood paste, mince, or meal.

imposed in the permit. The Director may establish alternative 
requirements less stringent than the requirements of Sec. 125.134(a) 
through (d) only if:
    (1) There is an applicable requirement under Sec. 125.134(a) 
through (d);

[[Page 423]]

    (2) The Director determines that data specific to the facility 
indicate that compliance with the requirement at issue would result in 
compliance costs wholly out of proportion to the costs EPA considered in 
establishing the requirement at issue or would result in significant 
adverse impacts on local water resources other than impingement or 
entrainment, or significant adverse impacts on energy markets;
    (3) The alternative requirement requested is no less stringent than 
justified by the wholly out of proportion cost or the significant 
adverse impacts on local water resources other than impingement or

entrainment); and a description of the abundance and temporal/spatial 
characterization of the target populations based on the collection of 
multiple years of data to capture the seasonal and daily activities 
(e.g., spawning, feeding and water column migration) of all life stages 
of fish and shellfish found in the vicinity of the cooling water intake 
structure;
    (2) An identification of all threatened or endangered species that 
might be susceptible to impingement and entrainment by the proposed 
cooling water intake structure(s); and
    (3) A description of additional chemical, water quality, and other

    (B) Evaluation of potential cooling water intake structure effects. 
This evaluation must include:
    (1) Calculations of the reduction in impingement mortality and, (if 
applicable), entrainment of all life stages of fish and shellfish that 
would need to be achieved by the technologies you have selected to 
implement to meet requirements under Track II. To do this, you must 
determine the reduction in impingement mortality and entrainment that 
would be achieved by implementing the requirements of Sec. 
125.134(b)(2) and, for facilities without sea chests, Sec. 
125.134(b)(5) of Track I at your site.
    (2) An engineering estimate of efficacy for the proposed and/or 
implemented technologies used to minimize impingement mortality and (if 
applicable) entrainment of all life stages of fish and shellfish and 
maximize survival of impinged life stages of fish and shellfish. You 
must demonstrate that the technologies reduce impingement mortality and 
(if applicable) entrainment of all life stages of fish and shellfish to 
a comparable level to that which you would achieve were you to implement 
the requirements in Sec. 125.134(b)(2) and, for facilities without sea 
chests, Sec. 125.134(b)(5) of Track I. The efficacy projection must 
include a site-specific evaluation of technology(ies) suitability for 
reducing impingement mortality and (if applicable) entrainment based on 
the results of the Source Water Biological Study in paragraph 
(c)(2)(iii)(A) of this section. Efficacy estimates may be determined 
based on case studies that have been conducted in the vicinity of the 
cooling water intake structure and/or site-specific technology prototype 
studies.
    (C) Verification monitoring plan. You must include in the Study a 
plan to conduct, at a minimum, two years of monitoring to verify the 
full-scale performance of the proposed or implemented technologies and/
or operational measures. The verification study must begin at the start 
of operations of the cooling water intake structure and continue for a 
sufficient period of time to demonstrate that the facility is reducing 
the level of impingement mortality and (if applicable) entrainment to 
the level documented in paragraph (c)(2)(iii)(B) of this section. The 
plan must describe the frequency of monitoring and the parameters to be 
monitored. The Director will use the verification monitoring to confirm 
that you are meeting the level of impingement mortality and entrainment 
reduction required in Sec. 125.134(c), and that the operation of the 
technology has been optimized.

Sec. 125.137  As an owner or operator of a new offshore oil and gas
extraction facility, must I perform monitoring?

    As an owner or operator of a new offshore oil and gas extraction 
facility, you will be required to perform monitoring to demonstrate your 
compliance with the requirements specified in Sec. 125.134 or 
alternative requirements under Sec. 125.135.
    (a) Biological monitoring. (1)(i) Fixed facilities without sea 
chests that choose to comply with the Track I requirements in Sec. 
125.134(b)(1)(i) must monitor for entrainment. These facilities are not 
required to monitor for impingement, unless the Director determines that 
the information would be necessary to evaluate the need for or 
compliance with additional requirements in accordance with Sec. 
125.134(b)(4) or more stringent requirements in accordance with Sec. 
125.134(d).
    (ii) Fixed facilities with sea chests that choose to comply with 
Track I requirements are not required to perform biological monitoring 
unless the Director determines that the information would be necessary 
to evaluate the need for or compliance with additional requirements in 
accordance with Sec. 125.134(b)(4) or more stringent requirements in 
accordance with Sec. 125.134(d).
    (iii) Facilities that are not fixed facilities are not required to 
perform biological monitoring unless the Director determines that the 
information would be necessary to evaluate the need for or compliance 
with additional requirements in accordance with Sec. 125.134(b)(4) or 
more stringent requirements in accordance with Sec. 125.134(d).
    (iv) Fixed facilities with sea chests that choose to comply with 
Track II requirements in accordance with Sec. 125.134(c), must monitor 
for impingement only. Fixed facilities without sea chests that choose to 
comply with Track II requirements, must monitor for both impingement and 
entrainment.
    (2) Monitoring must characterize the impingement rates and (if 
applicable) entrainment rates) of commercial, recreational, and forage 
base fish and shellfish species identified in the Source Water Baseline 
Biological Characterization data required by 40 CFR 122.21(r)(4), 
identified in the Comprehensive Demonstration Study required by Sec. 
125.136(c)(2), or as specified by the Director.
    (3) The monitoring methods used must be consistent with those used 
for the Source Water Baseline Biological Characterization data required 
in 40 CFR 122.21(r)(4), those used by the Comprehensive Demonstration 
Study required by Sec. 125.136(c)(2), or as specified by the Director. 
You must follow the monitoring frequencies identified below for at least 
two (2) years after the initial permit issuance. After that time, the 
Director may approve a request for less frequent sampling in the 
remaining years of the permit term and when the permit is reissued, if 
supporting data show that less frequent monitoring would still allow for 
the detection of any seasonal variations in the species and numbers of 
individuals that are impinged or entrained.
    (4) Impingement sampling. You must collect samples to monitor 
impingement rates (simple enumeration) for each species over a 24-hour 
period and no less than once per month when the cooling water intake 
structure is in operation.
    (5) Entrainment sampling. If your facility is subject to the 
requirements of Sec. 125.134(b)(1)(i), or if your facility is subject 
to Sec. 125.134(c) and is a fixed facility without a sea chest, you 
must collect samples to monitor entrainment rates (simple enumeration) 
for each species over a 24-hour period and no less than biweekly during 
the primary period of reproduction, larval recruitment, and peak 
abundance identified during the Source Water Baseline Biological 
Characterization required by 40 CFR 122.21(r)(4) or the Comprehensive 
Demonstration Study required in Sec. 125.136(c)(2). You must collect 
samples only when the cooling water intake structure is in operation.
    (b) Velocity monitoring. If your facility uses a surface intake 
screen systems, you must monitor head loss across the screens and 
correlate the measured value with the design intake velocity. The head 
loss across the intake screen must be measured at the minimum ambient 
source water surface elevation (best professional judgment based on 
available hydrological data). The maximum head loss across the screen 
for

[[Page 427]]

each cooling water intake structure must be used to determine compliance 
with the velocity requirement in Sec. 125.134(b)(2). If your facility 
uses devices other than surface intake screens, you must monitor 
velocity at the point of entry through the device. You must monitor head 
loss or velocity during initial facility startup, and thereafter, at the 
frequency specified in your NPDES permit, but no less than once per 
quarter.
    (c) Visual or remote inspections. You must either conduct visual 
inspections or employ remote monitoring devices during the period the 
cooling water intake structure is in operation. You must conduct visual 
inspections at least weekly to ensure that any design and construction 
technologies required in Sec. 125.134(b)(4), (b)(5), (c), and/or (d) 
are maintained and operated to ensure that they will continue to 
function as designed. Alternatively, you must inspect via remote 
monitoring devices to ensure that the impingement and entrainment 
technologies are functioning as designed.



Sec. 125.138  As an owner or operator of a new offshore oil and gas
extraction facility, must I keep records and report?

    As an owner or operator of a new offshore oil and gas extraction 
facility you are required to keep records and report information and 
data to the Director as follows:
    (a) You must keep records of all the data used to complete the 
permit application and show compliance with the requirements, any 
supplemental information developed under Sec. 125.136, and any 
compliance monitoring data submitted under Sec. 125.137, for a period 
of at least three (3) years from the date of permit issuance. The 
Director may require that these records be kept for a longer period.
    (b) You must provide the following to the Director in a yearly 
status report:
    (1) For fixed facilities, biological monitoring records for each 
cooling water intake structure as required by Sec. 125.137(a);
    (2) Velocity and head loss monitoring records for each cooling water 
intake structure as required by Sec. 125.137(b); and
    (3) Records of visual or remote inspections as required in Sec. 
125.137(c).



Sec. 125.139  As the Director, what must I do to comply with the 
requirements of this subpart?

    (a) Permit application. As the Director, you must review materials 
submitted by the applicant under 40 CFR 122.21(r), Sec. 125.135, and 
Sec. 125.136 at the time of the initial permit application and before 
each permit renewal or reissuance.
    (1) After receiving the initial permit application from the owner or 
operator of a new offshore oil and gas extraction facility, the Director 
must determine applicable standards in Sec. 125.134 or Sec. 125.135 to 
apply to the new offshore oil and gas extraction facility. In addition, 
the Director must review materials to determine compliance with the 
applicable standards.
    (2) For each subsequent permit renewal, the Director must review the 
application materials and monitoring data to determine whether 
requirements, or additional requirements, for design and construction 
technologies or operational measures should be included in the permit.
    (3) For Track II facilities, the Director may review the information 
collection proposal plan required by Sec. 125.136(c)(2)(ii). The 
facility may initiate sampling and data collection activities prior to 
receiving comment from the Director.
    (b) Permitting requirements. Section 316(b) requirements are 
implemented for a facility through an NPDES permit. As the Director, you 
must determine, based on the information submitted by the new offshore 
oil and gas extraction facility in its permit application, the 
appropriate requirements and conditions to include in the permit based 
on the track (Track I or Track II), or alternative requirements in 
accordance with Sec. 125.135, the new offshore oil and gas extraction 
facility has chosen to comply with. The following requirements must be 
included in each permit:
    (1) Cooling water intake structure requirements. At a minimum, the 
permit conditions must include the performance standards that implement 
the applicable requirements of Sec. 125.134(b)(2),

[[Page 428]]

(3), (4) and (5); Sec. 125.134(c)(1) and (2); or Sec. 125.135.
    (i) For a facility that chooses Track I, you must review the Design 
and Construction Technology Plan required in Sec. 125.136(b)(3) to 
evaluate the suitability and feasibility of the technology proposed to 
minimize impingement mortality and (if applicable) entrainment of all 
life stages of fish and shellfish. In the first permit issued, you must 
include a condition requiring the facility to reduce impingement 
mortality and/or entrainment commensurate with the implementation of the 
technologies in the permit. Under subsequent permits, the Director must 
review the performance of the technologies implemented and require 
additional or different design and construction technologies, if needed 
to minimize impingement mortality and/or entrainment of all life stages 
of fish and shellfish. In addition, you must consider whether more 
stringent conditions are reasonably necessary in accordance with Sec. 
125.134(d).
    (ii) For a fixed facility that chooses Track II, you must review the 
information submitted with the Comprehensive Demonstration Study 
information required in Sec. 125.136(c)(2), evaluate the suitability of 
the proposed design and construction technology and/or operational 
measures to determine whether they will reduce both impingement 
mortality and/or entrainment of all life stages of fish and shellfish to 
90 percent or greater of the reduction that could be achieved through 
Track I. In addition, you must review the Verification Monitoring Plan 
in Sec. 125.136(c)(2)(iii)(C) and require that the proposed monitoring 
begin at the start of operations of the cooling water intake structure 
and continue for a sufficient period of time to demonstrate that the 
technologies and operational measures meet the requirements in Sec. 
125.134(c)(1). Under subsequent permits, the Director must review the 
performance of the additional and /or different technologies or measures 
used and determine that they reduce the level of adverse environmental 
impact from the cooling water intake structures to a comparable level 
that the facility would achieve were it to implement the requirements of 
Sec. 125.134(b)(2) and, if applicable, Sec. 125.134(b)(5).
    (iii) If a facility requests alternative requirements in accordance 
with Sec. 125.135, you must determine if data specific to the facility 
meet the requirements in Sec. 125.135(a) and include in the permit 
requirements that are no less stringent than justified by the wholly out 
of proportion cost or the significant adverse impacts on local water 
resources other than impingement or entrainment, or significant adverse 
impacts on energy markets.
    (2) Monitoring conditions. At a minimum, the permit must require the 
permittee to perform the monitoring required in Sec. 125.137. You may 
modify the monitoring program when the permit is reissued and during the 
term of the permit based on changes in physical or biological conditions 
in the vicinity of the cooling water intake structure. The Director may 
require continued monitoring based on the results of monitoring done 
pursuant to the Verification Monitoring Plan in Sec. 
125.136(c)(2)(iii)(C).
    (3) Record keeping and reporting. At a minimum, the permit must 
require the permittee to report and keep records as required by Sec. 
125.138.

    Source: 80 FR 64102, Oct. 22, 2015, unless otherwise noted.



                            Subpart A_General



Sec. 127.1  Purpose and scope.

    (a) This part, in conjunction with the NPDES reporting requirements 
specified in 40 CFR parts 122, 123, 124, 125, 403, 501, and 503, 
specifies the requirements for:
    (1) Electronic reporting of information by NPDES permittees;
    (2) Facilities or entities seeking coverage under NPDES general 
permits;
    (3) Facilities or entities submitting stormwater certifications or 
waivers from NPDES permit requirements;
    (4) Industrial users located in municipalities without approved 
local pretreatment programs;
    (5) Approved pretreatment programs;
    (6) Facilities or entities regulated by the Federal sewage sludge/
biosolids program; and
    (7) EPA and the states, tribes, or territories that have received 
authorization from EPA to implement the NPDES program. This part, in 
conjunction with 40 CFR parts 123, 403, and 501, also specifies the 
requirements for electronic reporting of NPDES information to EPA by the 
states, tribes, or territories that have received authorization from EPA 
to implement the NPDES program.
    (b) These regulations are not intended to preclude states, tribes, 
or territories authorization from EPA to implement the NPDES program 
from developing and using their own NPDES data systems. However, these 
states, tribes, and territories must ensure that the required minimum 
set of NPDES data (appendix A of this part) is electronically 
transferred to EPA in a timely, accurate, complete, and nationally-
consistent manner fully compatible with EPA's national NPDES data 
system.
    (c) Under 10 U.S.C. 130e, the Secretary of Defense may exempt 
Department of Defense ``critical infrastructure security information'' 
from disclosure under the Freedom of Information Act (FOIA). NPDES 
program data designated as critical infrastructure security information 
in response to a FOIA request will be withheld from the public. In the 
instance where an NPDES program data element for a particular facility 
is designated as critical infrastructure security information in 
response to a FOIA request, a separate filtered set of data without the 
redacted information will be shared with the public; however, all NPDES 
program data will continue to be provided to EPA and the authorized 
state, tribe, or territory NPDES program.
    (d) Proper collection, management, and sharing of the data and 
information listed in appendix A ensures that there is timely, complete, 
accurate, and nationally-consistent set of data about the NPDES program.



Sec. 127.2  Definitions.

    (a) The definitions in 40 CFR parts 122, 123, 124, 125, 403, 501 and 
503 apply to all subparts of this part.
    (b) Initial recipient of electronic NPDES information from NPDES-
regulated facilities (initial recipient) means the entity (EPA or the 
state, tribe, or territory authorized by EPA to implement the NPDES 
program) that is the designated entity for receiving electronic NPDES 
data. Section 127.27 outlines the process for designating the initial 
recipient of electronic NPDES information from NPDES-regulated 
facilities.

[[Page 430]]

EPA must become the initial recipient of electronic NPDES information 
from NPDES-regulated facilities if the state, tribe, or territory does 
not collect the data required in appendix A to this part and does not 
consistently maintain timely, accurate, complete, and consistent data 
transfers in compliance with this part and 40 CFR part 3. Timely means 
that the authorized state, tribe, or territory submits these data 
transfers (see the data elements in appendix A to this part) to EPA 
within 40 days of when the authorized program completed the activity or 
received a report submitted by a regulated entity. For example, the data 
regarding a state inspection of an NPDES-regulated entity that is 
finalized by the state on October 5th must be electronically transferred 
to EPA no later than November 14th of that same year (e.g., 40 days 
after October 5th).
    (c) NPDES data group means the group of related data elements 
identified in Table 1 in appendix A to this part. These NPDES data 
groups have similar regulatory reporting requirements and have similar 
data sources.
    (d) NPDES program means the National Pollutant Discharge Elimination 
System (Clean Water Act section 402); the Federal Sewage Sludge 
(Biosolids) Program (Clean Water Act section 405); and the Federal 
Pretreatment Program (Clean Water Act section 307(b); 40 CFR part 403). 
EPA can implement the NPDES program or authorize states, tribes, and 
territories to implement the NPDES program (``authorized NPDES 
program''). Identifying the relevant authority must be done for each 
NPDES subprogram (e.g., NPDES core program, federal facilities, general 
permits, pretreatment, and sewage sludge/biosolids).
    (e) Minimum set of NPDES data means the data and information listed 
in appendix A to this part.
    (f) Program reports means the information reported by NPDES-
regulated entities and listed in Table 1 of appendix A to this part 
(except NPDES Data Groups 1, 2, and 3).
    (g) Hybrid approach is a method that the initial recipient [as 
defined in paragraph (b) of this section] may elect to use for 
construction stormwater general permit reports [Notices of Intent to 
discharge (NOIs); Notices of Termination (NOTs); No Exposure 
Certifications (NOEs); Low Erosivity Waivers (LEWs)] [40 CFR 
122.26(b)(15), 122.28 and 122.64] in order to demonstrate compliance 
with this part. This alternative compliance method allows the initial 
recipient (the authorized state, tribe, territory or EPA) to use a non-
CROMERR electronic submission along with a uniquely matched paper 
submission, to reflect conditions at construction sites. Specifically, 
this approach allows the initial recipient to use data capture 
technologies to collect construction stormwater general permit reports. 
For example, under this approach the initial recipient may allow 
construction operators to complete an electronic construction stormwater 
general permit report, which simultaneously produces a paper copy of the 
report and electronically transmits a copy of the data from the report 
to the authorized NPDES program. Under this approach the construction 
operator must sign and date the paper copy of the construction 
stormwater general permit report with a ``wet-ink'' signature and this 
paper document will be the copy of record. Under this approach the 
initial recipient must have the ability to definitively and uniquely 
link the signed and dated paper document with the electronic submission 
from the facility or entity (e.g., use of a unique code or mark on the 
signed and dated paper document that is also embedded in the electronic 
submission). Under this approach the initial recipient may also use 
automated data capture technologies (e.g., Optical Character 
Recognition), which allow construction operators to submit their general 
permit reports to the initial recipient on paper with a ``wet-ink'' 
signature and date in a structured format that allows for easy data 
importation into the initial recipient's NPDES data system.
    (h) NPDES-regulated entity means any entity regulated by the NPDES 
program.

    (b) Facilities or entities seeking coverage under or termination 
from NPDES general permits and facilities or entities submitting 
stormwater certifications or waivers from NPDES permit requirements [see 
Exhibit 1 to 40 CFR 122.26(b)(15) and (g)] must electronically submit 
the minimum set of NPDES data for the following notices, certifications, 
and waivers (if such reporting requirements are applicable):
    (1) Notice of intent (NOI) to discharge by facilities seeking 
coverage under a general NPDES permit (rather than an individual NPDES 
permit), as described in 40 CFR 122.28(b)(2);
    (2) Notice of termination (NOT), as described in 40 CFR 122.64;
    (3) No exposure certification (NOE), as described in 40 CFR 
122.26(g)(1)(iii); and
    (4) Low erosivity waiver (LEW) and another waiver as described in 
Exhibit 1 to 40 CFR 122.26(b)(15).
    (c) Industrial users located in municipalities without approved 
local pretreatment programs must electronically submit the minimum set 
of NPDES data for the following self-monitoring reports (if such 
reporting requirements are applicable):
    (1) Periodic reports on continued compliance, as described in 40 CFR 
403.12(e); and
    (2) Reporting requirements for Industrial Users not subject to 
categorical Pretreatment Standards, as described in 40 CFR 403.12(h).
    (d) The minimum set of NPDES data for NPDES-regulated facilities is 
identified in appendix A to this part.



Sec. 127.12  Signature and certification standards for electronic
reporting.

    The signatory and certification requirements identified in 40 CFR 
part 3 (including, in all cases, subpart D to part 3), Sec. 122.22, and 
40 CFR 403.12(l) must also apply to electronic submissions of NPDES 
information (see Sec. 127.11) by NPDES permittees, facilities, and 
entities subject to this part [see Sec. 127.1(a)].



Sec. 127.13  Requirements regarding quality assurance and 
quality control.

    (a) Responsibility for the quality of the information provided 
electronically in compliance with this part by the NPDES permittees, 
facilities, and entities subject to this part [see Sec. 127.1(a)] rests 
with the owners and operators of those facilities or entities. NPDES 
permittees, facilities, and entities subject to this part must use 
quality assurance and quality control procedures to ensure the quality 
of the NPDES information submitted in compliance with this part.
    (b) NPDES permittees, facilities, and entities subject to this part 
must electronically submit their NPDES information in compliance with 
the data quality requirements specified in Sec. 127.14. NPDES 
permittees, facilities, and entities subject to this part must 
electronically submit their NPDES information unless a waiver is granted 
in compliance with this part (see Sec. Sec. 127.15 and 127.24).

[[Page 432]]



Sec. 127.14  Requirements regarding timeliness, accuracy, 
completeness, and national consistency.

    NPDES permittees, facilities, and entities subject to this part [see 
Sec. 127.1(a)] must comply with all requirements in this part and 
electronically submit the minimum set of NPDES data in the following 
nationally-consistent manner:
    (a) Timely. Electronic submissions of the minimum set of NPDES data 
to the appropriate initial recipient, as defined in Sec. 127.2(b), must 
be timely.
    (1) Measurement data (including information from discharge 
monitoring reports, self-monitoring data from industrial users located 
outside of approved local pretreatment programs, and similar self-
monitoring data). The electronic submission of these data is due when 
that monitoring information is required to be reported in compliance 
with statutes, regulations, the NPDES permit, another control mechanism, 
or an enforcement order.
    (2) Program report data. The electronic submission of this data is 
due when that program report data is required to be reported in 
compliance with statutes, regulations, the NPDES permit, another control 
mechanism, or an enforcement order.
    (b) Accurate. Electronic submissions of the minimum set of NPDES 
data must be identical to the actual measurements taken by the owner, 
operator, or their duly authorized representative;
    (c) Complete. Electronic submission of the minimum set of NPDES data 
must include all required data (see appendix A to this part) and these 
electronic submissions must be sent to the NPDES data system of the 
initial recipient, as defined in Sec. 127.2(b); and
    (d) Consistent. Electronic submissions of the minimum set of NPDES 
data must be compliant with EPA data standards as set forth in this part 
and in a form (including measurement units) and be fully compatible with 
EPA's national NPDES data system.



Sec. 127.15  Waivers from electronic reporting.

    (a) NPDES permittees, facilities, and entities subject to this part 
[see Sec. 127.1(a)] must electronically submit the minimum set of NPDES 
data in compliance with this part, 40 CFR part 3 (including, in all 
cases, subpart D to part 3), 40 CFR 122.22, and 40 CFR 403.12(l) unless 
a waiver is granted in compliance with this section and Sec. 127.24.
    (b) Temporary waivers from electronic reporting may be granted by 
the authorized NPDES program (EPA, or states, territories, and tribes 
that have received authorization to implement the NPDES program), in 
compliance with this section and Sec. 127.24, to NPDES permittees, 
facilities, and entities subject to this part [see Sec. 127.1(a)].
    (1) Each temporary waiver must not extend beyond five years. 
However, NPDES-regulated entities may re-apply for a temporary waiver. 
It is the duty of the owner, operator, or duly authorized representative 
of the NPDES permittee, facility, and entity subject to this part [see 
Sec. Sec. 122.22 of this chapter and 127.1(a)] to re-apply for a new 
temporary waiver. Authorized NPDES programs cannot grant a temporary 
waiver to an NPDES-regulated entity without first receiving a temporary 
waiver request from the NPDES-regulated entity.
    (2) To apply for a temporary waiver, the owner, operator, or duly 
authorized representative of the NPDES permittee, facility, and entity 
subject to this part [see Sec. Sec. 122.22 of this chapter and 
127.1(a)] must submit the following information to their authorized 
NPDES program:
    (i) Facility name;
    (ii) NPDES permit number (if applicable);
    (iii) Facility address;
    (iv) Name, address and contact information for the owner, operator, 
or duly authorized facility representative;
    (v) Brief written statement regarding the basis for claiming such a 
temporary waiver; and
    (vi) Any other information required by the authorized NPDES program.
    (3) The authorized NPDES program will determine whether to grant a 
temporary waiver. The authorized NPDES program must provide notice to 
the owner, operator, or duly authorized facility representative 
submitting a temporary waiver request, in compliance with the 
requirements of Sec. 127.24.

[[Page 433]]

    (4) NPDES permittees, facilities, and entities subject to this part 
[see Sec. 127.1(a)] that have received a temporary waiver must continue 
to provide the minimum set of NPDES data (as well as other required 
information in compliance with statutes, regulations, the NPDES permit, 
another control mechanism, or an enforcement order) in hard-copy format 
to the authorized NPDES program. The authorized NPDES program must 
electronically transfer these data to EPA in accordance with subpart C 
of this part.
    (5) An approved temporary waiver is not transferrable.
    (c) Permanent waivers from electronic reporting may be granted by 
the authorized NPDES program (EPA, or states, territories, and tribes 
that have received authorization to implement the NPDES program), in 
compliance accordance with this section and Sec. 127.24, to NPDES 
permittees, facilities, and entities subject to this part [see Sec. 
127.1(a)].
    (1) Permanent waivers are only available to facilities and entities 
owned or operated by members of religious communities that choose not to 
use certain modern technologies (e.g., computers, electricity). 
Authorized NPDES programs cannot grant a permanent waiver to an NPDES-
regulated entity without first receiving a permanent waiver request from 
the NPDES-regulated entity.
    (2) To apply for a permanent waiver, the owner, operator, or duly 
authorized representative of the NPDES permittee, facility, and entity 
subject to this part [see Sec. Sec. 122.22 of this chapter and 
127.1(a)] must submit the information listed in Sec. 127.15(b)(2) to 
their authorized NPDES program.
    (3) An approved permanent waiver is not transferrable.
    (4) NPDES permittees, facilities, and entities subject to this part 
[see Sec. 127.1(a)] that have received a permanent waiver must continue 
to provide the minimum set of NPDES data (as well as other required 
information in compliance with statutes, regulations, the NPDES permit, 
another control mechanism, or an enforcement order) in hard-copy format 
to the authorized NPDES program. The authorized NPDES program must 
electronically transfer these data to EPA in accordance with subpart C 
of this part.
    (d) Episodic waivers from electronic reporting may be granted by the 
authorized NPDES program (EPA, or states, territories, and tribes that 
have received authorization to implement the NPDES program) or the 
initial recipient, as defined in Sec. 127.2(b), in compliance 
accordance with this section and Sec. 127.24, to NPDES permittees, 
facilities, and entities subject to this part [see Sec. 127.1(a)]. The 
following conditions apply to episodic waivers.
    (1) No waiver request from the NPDES permittee, facility or entity 
is required to obtain an episodic waiver from electronic reporting.
    (2) Episodic waivers are not transferrable.
    (3) Episodic waivers cannot last more than 60 days.
    (4) The authorized NPDES program or initial recipient will decide if 
the episodic waiver provision allows facilities and entities to delay 
their electronic submissions or to send hardcopy (paper) submissions. 
Episodic waivers are only available to facilities and entities in the 
following circumstances:
    (i) Large scale emergencies involving catastrophic circumstances 
beyond the control of the facilities, such as forces of nature (e.g., 
hurricanes, floods, fires, earthquakes) or other national disasters. The 
authorized NPDES program will make the determination if an episodic 
waiver is warranted in this case and must receive the hardcopy (paper) 
submissions.
    (ii) Prolonged electronic reporting system outages (i.e., outages 
longer than 96 hours). The initial recipient, which may also be the 
authorized NPDES program, will make the determination if an episodic 
waiver is warranted in this case and must receive the hardcopy (paper) 
submissions.



Sec. 127.16  Implementation of electronic reporting requirements for
NPDES permittees, facilities, and entities subject to this part
[see Sec. 127.1(a)].

    (a) Scope and schedule. NPDES permittees, facilities, and entities 
subject to this part [see Sec. 127.1(a)], with the exception of those 
covered by waivers under Sec. Sec. 127.15 and 127.24, must 
electronically submit the following NPDES

Control Authority, Approval Authority, or initial recipient [as 
identified in Sec. 127.27, and as defined in Sec. 127.2(b)]. EPA must 
identify and publish the initial recipient on an EPA Web site and in the 
Federal Register, by state and by NPDES data group [see Sec. 127.2(c)].
    (d) Standards for NPDES regulated entities with electronic reporting 
waivers. NPDES permittees, facilities, and entities subject to this part 
[see Sec. 127.1(a)] that have received a waiver from electronic 
reporting must continue to provide the minimum set of NPDES data (as 
well as other required information in compliance with statutes, 
regulations, the NPDES permit, another control mechanism, or an 
enforcement order) to the authorized NPDES program or initial recipient 
(see Sec. 127.15).



 Subpart C_Responsibilities of EPA and States, Tribes, and Territories 
                Authorized to Implement the NPDES Program



Sec. 127.21  Data to be reported electronically to EPA by states, 
tribes, and territories.

    (a) States, tribes, and territories that have received authorization 
from EPA to implement the NPDES program must electronically transfer to 
EPA all information listed in appendix A to this part. This information 
includes:
    (1) The ``Core NPDES Permitting, Compliance, And Enforcement Data 
[40 CFR parts 122, 123, 403, 503]'' as identified as NPDES Data Group 1 
in Tables 1 and 2 in appendix A to this part.
    (2) NPDES information (NPDES Data Groups 2 through 10 in Tables 1 
and 2 in appendix A to this part) from NPDES permittees, facilities, and 
entities subject to this part [see Sec. 127.1(a)] where the authorized 
state, tribe, or territory is the initial recipient [as identified in 
Sec. 127.27, and as defined in Sec. 127.2(b)]. This includes NPDES 
information from NPDES permittees, facilities, and entities subject to 
this part that received a waiver from electronic reporting (see Sec. 
127.15).

[[Page 435]]

    (3) Specific data elements that are required to be submitted 
electronically to EPA by the states, tribes, or territories that have 
received authorization from EPA to implement the NPDES program are 
identified in appendix A to this part.
    (b) States, tribes, and territories that have received authorization 
from EPA to implement the NPDES program must electronically transfer 
these data, listed in Sec. 127.21(a), to EPA within 40 days of the 
completed activity or within 40 days of the receipt of a report from an 
NPDES permittee, facility, or entity subject to this part [see Sec. 
127.1(a)].



Sec. 127.22  Requirements regarding quality assurance and quality control.

    States, tribes, and territories that have received authorization 
from EPA to implement the NPDES program have the responsibility for the 
information that they electronically transfer to EPA. Therefore, 
authorized states, tribes, and territories that electronically transfer 
data to EPA must use reasonable quality assurance and quality control 
procedures to ensure the quality of the NPDES information.



Sec. 127.23  Requirements regarding timeliness, accuracy, 
completeness, and national consistency.

    (a) Authorized state, tribe, and territory NPDES programs must 
electronically transfer all NPDES program data that supports electronic 
reporting (e.g., facility information and permit information such as 
limits, permitted features, and narrative conditions) to EPA three 
months prior to the electronic reporting start dates in Table 1 in Sec. 
127.16(a) and maintain updates thereafter. These electronic data 
transfers must be timely, accurate, complete, and consistent.
    (b) According to the schedule set forth in Sec. 127.16, the 
authorized NPDES program must electronically transfer to EPA the minimum 
set of NPDES data (as specified in appendix A to this part). These 
electronic data transfers to EPA must be timely, accurate, complete, and 
consistent.
    (c) For the purposes of this part timely, accurate, complete, and 
consistent mean:
    (1) Timely, in that the authorized state, tribe, or territory NPDES 
program electronically transfers the minimum set of NPDES data to EPA 
within 40 days of the completed activity or within 40 days of receipt of 
a report from an NPDES permittee, facility, or entity subject to this 
part [see Sec. 127.1(a)]. For example, the data regarding a state 
inspection of an NPDES-regulated entity that is finalized by the state 
on October 5th must be electronically transferred to EPA no later than 
November 14th of that same year (e.g., 40 days after October 5th). The 
start dates for electronic reporting from NPDES permittees, facilities, 
and entities subject to this part [see Sec. 127.1(a)] are provided in 
Table 1 in Sec. 127.16(a).
    (2) Accurate, in that 95% or more of the minimum set of NPDES data 
in EPA's national NPDES data system are identical to the actual 
information on the copy of record (e.g., permit, notice, waiver, 
certification, report, enforcement order, or other source document);
    (3) Complete, in that 95% or more of submissions required for each 
NPDES data group [see Sec. 127.2(c)] are available in EPA's national 
NPDES data system; and
    (4) Consistent, in that data electronically submitted by states, 
tribes, and territories to EPA, by direct entry of information, data 
transfers from one data system to another, or some combination thereof, 
into EPA's designated national NPDES data system is in compliance with 
EPA's data standards as set forth in this part and in a form and 
measurement units which are fully compatible with EPA's national NPDES 
data system.
    (d) An authorized program must consistently maintain the 
requirements identified in paragraph (a) of this section in order to be 
the initial recipient, as defined in Sec. 127.2(b). If the authorized 
program does not maintain these requirements, EPA must become the 
initial recipient (see Sec. 127.27).

[[Page 436]]



Sec. 127.24  Responsibilities regarding review of waiver requests 
from NPDES permittees, facilities, and entities subject to this part
[see Sec. 127.1(a)].

    (a) Under Sec. 127.15, an NPDES permittee, facility, or entity 
subject to this part [see Sec. 127.1(a)] may seek a waiver from 
electronic reporting. States, tribes, and territories that have received 
authorization from EPA to implement the NPDES program must review the 
temporary or permanent waiver requests that they receive and either 
approve or reject these requests within 120 days.
    (b) The authorized NPDES state, tribe, or territory program must 
provide the permittee, facility, or entity with notice of the approval 
or rejection of their temporary or permanent waiver request from 
electronic reporting.
    (c) The authorized NPDES state, tribal, or territory program must 
electronically transfer to EPA the minimum set of NPDES data (as 
specified in appendix A to this part) that they receive from permittees, 
facilities, or entities with a waiver from electronic reporting in 
accordance with Sec. 127.23.
    (d) Under Sec. 127.15(d), episodic waivers from electronic 
reporting may be granted by the authorized NPDES program or the initial 
recipient to NPDES permittees, facilities, and entities. The authorized 
NPDES program or initial recipient granting an episodic waiver must 
provide notice, individually or through means of mass communication, 
regarding when such an episodic waiver is available, the facilities and 
entities that may use the episodic waiver, the likely duration of the 
episodic waiver, and any other directions regarding how facilities and 
entities should provide the minimum set of NPDES data (as well as other 
required information in compliance with statutes, regulations, the NPDES 
permit, another control mechanism, or an enforcement order) to the 
authorized NPDES program or the initial recipient. No waiver request 
from the NPDES permittee, facility or entity is required to obtain an 
episodic waiver from electronic reporting. The authorized NPDES program 
or initial recipient granting the episodic waiver will determine whether 
to allow facilities and entities to delay their electronic submissions 
for a short time (i.e., no more than 40 days) or to send hardcopy 
(paper) submissions.



Sec. 127.25  Time for states, tribes, and territories to revise
existing programs.

    A state, tribe, or territory that has received authorization from 
EPA to implement the NPDES program must make program revisions in 
compliance with 40 CFR 123.62(e).



Sec. 127.26  Implementation plan (authorized states, tribes,
and territories).

    (a) Initial recipient designation procedure. EPA and authorized 
state, tribe, and territory NPDES programs must follow the procedure in 
Sec. 127.27 for determining the initial recipient of electronic NPDES 
information from NPDES-regulated facilities (see Sec. 127.2(b)).
    (b) NPDES data system requirements. Authorized state, tribe, and 
territory NPDES programs must update their electronic data system to 
electronically collect the minimum set of NPDES data and facilitate 
compliance with this part (including Sec. Sec. 127.22 and 127.23) and 
40 CFR part 3. The authorized NPDES program's electronic data system 
must facilitate electronic reporting from NPDES permittees, facilities, 
and entities subject to this part [see Sec. 127.1(a)] in compliance 
with the start dates in Table 1 in Sec. 127.16(a). Authorized NPDES 
programs may elect to use EPA's national NPDES data system (and related 
Internet services and applications) for their electronic data system.
    (c) Preparatory actions for electronic reporting. Authorized state, 
tribe, and territory NPDES programs must electronically transfer all 
NPDES data that supports electronic reporting (e.g., permitting, 
compliance monitoring, compliance determinations, and enforcement 
activities) to EPA's national NPDES data system three months prior to 
the electronic reporting start dates in Table 1 in Sec. 127.16(a) and 
maintain updates thereafter. These electronic data transfers must be 
timely, accurate, complete, and consistent (see Sec. 127.23).

[[Page 437]]

    (d) Transfer of NPDES program data to EPA. A state, tribe, or 
territory that is designated by EPA as the initial recipient [see 
Sec. Sec. 127.2(b) and 127.27] for an NPDES data group [as defined in 
Sec. 127.2(c)] must electronically collect and maintain the minimum set 
of NPDES data (as specified in appendix A to this part) and 
electronically transfer these data to EPA's national NPDES data system 
through timely, accurate, complete, and consistent electronic data 
transfers in compliance with this part (including Sec. Sec. 127.22 and 
127.23) and 40 CFR part 3.
    (e) Updating state statutes and regulations. Authorized state, 
tribe, or territory NPDES programs must update their NPDES programs to 
implement this part. See 40 CFR 123.62(e).
    (f) Inclusion of electronic reporting requirements in NPDES permits. 
All permits issued by the EPA and the authorized states, tribes, or 
territory NPDES program must contain permit conditions requiring 
compliance with the electronic reporting requirements in this part, 40 
CFR part 3, and 40 CFR 122.22. NPDES-regulated facilities which already 
have electronic reporting requirements in their permits that meet the 
requirements in this part, 40 CFR part 3, and 40 CFR 122.22 must 
continue their electronic reporting to the initial recipient [see 
Sec. Sec. 127.2(b) and 127.27].
    (g) Hybrid approach. Authorized state, tribe, or territory NPDES 
programs may elect to use the Hybrid Approach [as defined in Sec. 
127.2(g)] for the collection of the minimum set of NPDES data contained 
in construction stormwater general permit reports [see Table 1 in Sec. 
127.16(a)].
    (h) Authorized NPDES program implementation plans. A state, tribe, 
or territory that is designated by EPA as the initial recipient [see 
Sec. Sec. 127.2(b) and 127.27] for an NPDES data group [as defined in 
Sec. 127.2(c)] must submit an implementation plan to EPA for review. 
EPA will inform the authorized NPDES program if the implementation plan 
is adequate. This plan must provide enough details (e.g., tasks, 
milestones, roles and responsibilities, necessary resources) to clearly 
describe how the program will successfully implement this part 
(including a description of their electronic reporting waiver approval 
process); however, this plan does not include electronic reporting of 
Discharge Monitoring Reports or Forms Provided or Specified by the 
Director (DMRs) [40 CFR 122.41(l)(4)]. These implementation plans must 
be submitted to EPA by December 21, 2016 for EPA review.
    (i) Updating waiver approval process. A state, tribe, or territory 
that is designated by EPA as the initial recipient [see Sec. Sec. 
127.2(b) and 127.27] for an NPDES data group [as defined in Sec. 
127.2(c)] must submit an updated waiver approval process to EPA every 
five years. EPA will inform the authorized NPDES program if the waiver 
approval process adequate.
    (j) Electronic participation rates assessment. EPA will assess the 
electronic reporting participation rate of NPDES permittees, facilities, 
and entities subject to this part [see Sec. 127.1(a)] for each 
authorized NPDES program and by each NPDES data group to determine the 
appropriateness of using use its authority to increase the electronic 
reporting percentage rate.
    (1) EPA will separately calculate the electronic reporting 
participation rate for each authorized NPDES program and for each NPDES 
data group six months after the deadline for conversion from paper to 
electronic submissions [see the start dates for electronic reporting in 
Table 1 in Sec. 127.16(a)]. EPA will assess the electronic reporting 
participation rate for individually permitted facilities separate from 
the electronic reporting participation rate for general permit covered 
facilities for Discharge Monitoring Reports [NPDES Data Group Number 3].
    (2) As appropriate, EPA will contact the facilities and entities 
that are not electronically reporting their reports, notices, waivers, 
and certifications after the start dates for electronic reporting [see 
Table 1 in Sec. 127.16(a)]. EPA will not contact facilities and 
entities with waivers from electronic reporting (see Sec. 127.15). EPA 
will direct these facilities and entities to use the electronic 
reporting system of the initial recipient [as identified in Sec. 
127.27, and as defined in Sec. 127.2(b)].

[[Page 438]]

    (3) EPA will annually repeat its review of the electronic reporting 
participation rate for each authorized NPDES program and for each NPDES 
group as appropriate and contact facilities and entities as appropriate 
to use the electronic reporting system of the initial recipient [as 
identified in Sec. 127.27, and as defined in Sec. 127.2(b)].



Sec. 127.27  Procedure for determining initial recipient of electronic
NPDES information.

    (a) An authorized NPDES program must notify EPA by April 19, 2016 if 
it wishes EPA to be the initial recipient for a particular NPDES data 
group.
    (b) A state, tribe, or territory that seeks authorization to 
implement an NPDES program after March 21, 2016 must describe if it is 
requesting to be the initial recipient of electronic NPDES information 
from NPDES-regulated facilities for specific NPDES data groups. See 40 
CFR 123.22(g) and appendix A to this part.
    (c) By July 18, 2016, EPA must publish on its Web site and in the 
Federal Register a listing of the initial recipients for electronic 
NPDES information from NPDES-regulated facilities by state, tribe, and 
territory and by NPDES data group. This listing must identify for NPDES-
regulated facilities the initial recipient of their NPDES electronic 
data submissions and the due date for these NPDES electronic data 
submissions. EPA must update this listing on its Web site and in the 
Federal Register if a state, tribe, or territory gains authorization 
status to implement an NPDES program and is also approved by EPA to be 
the initial recipient of NPDES electronic data submissions for that 
program.
    (d) Failure to maintain all the requirements in this part and 40 CFR 
part 3 must prohibit the state, territory, or tribe from being the 
initial recipient of electronic NPDES information from NPDES-regulated 
entities. The following is the process for these determinations:
    (1) EPA must make a preliminary determination identifying if an 
authorized state, tribe, or territory is not complying with the 
requirements in this part and 40 CFR part 3 to be an initial recipient 
of electronic NPDES information from NPDES-regulated facilities. EPA 
must provide to the Director of the authorized NPDES program the 
rationale for any such preliminary determination and options for 
correcting these deficiencies. Within 60 days of EPA's preliminary 
determination, the authorized state, tribe, or territory must fully 
correct all deficiencies identified by EPA and notify EPA that such 
corrections have been completed. No response from the Director of the 
authorized NPDES program must indicate that the state, territory, or 
tribe agrees to be removed as the initial recipient for that NPDES data 
group of electronic NPDES information. Within 90 days of the EPA's 
preliminary determination, EPA must provide to the Director of the 
authorized NPDES program a final determination whether the state, tribe, 
or territory is not complying with the requirements in this part and 40 
CFR part 3 to be an initial recipient of electronic NPDES information 
from NPDES-regulated facilities.
    (2) EPA must become the initial recipient of electronic NPDES 
information from NPDES-regulated facilities if the state, tribe, or 
territory does not consistently maintain electronic data transfers in 
compliance with this part and 40 CFR part 3.
    (3) EPA must update the initial recipient listing described in 
paragraph (c) of this section and publish this listing on its Web site 
and in the Federal Register when it provides a final determination 
described in paragraph (d)(1) of this section to the Director of the 
authorized NPDES program.
    (4) Following any determination of noncompliance made in compliance 
with paragraph (d)(1) of this section, EPA will work with the Director 
of the authorized NPDES program to remediate all issues identified by 
EPA that prevent the authorized NPDES program from being the initial 
recipient. When the issues identified by EPA are satisfactorily 
resolved, EPA must update the initial recipient listing in paragraph (c) 
of this section in order to list the authorized state, tribe, or 
territory as the initial recipient for the one or more NPDES data 
groups. EPA

[[Page 439]]

will publish this revised initial recipient listing on its Web site and 
in the Federal Register.
    (e) An authorized NPDES program can initially elect for EPA to be 
the initial recipient for one or all of the NPDES data groups and then 
at a later date seek EPA approval to change the initial recipient status 
for one or all of the NPDES data groups from EPA to the authorized 
state, tribe, or territory. To make this switch, the authorized state, 
tribe, or territory will send a request to EPA. This request must 
identify the specific NPDES data groups for which the state, tribe, or 
territory would like to be the initial recipient of electronic NPDES 
information, a description of how its data system will be compliant with 
this part and 40 CFR part 3, and the date or dates when the state, 
tribe, or territory will be ready to start receiving this information. 
After EPA approval of the request, EPA will update the initial recipient 
list and will publish the revised initial recipient listing on its Web 
site and in the Federal Register.
    (f) An authorized NPDES program can initially elect to be the 
initial recipient for one or all of the NPDES data groups and then at a 
later date request that EPA become the initial recipient for one or all 
of the NPDES data groups. To make this switch, the authorized state, 
tribe, or territory will send a request to EPA. After coordination with 
the state EPA will update the initial recipient list and will publish 
the revised initial recipient listing on its Web site and in the Federal 
Register.



         Sec. Appendix A to Part 127--Minimum Set of NPDES Data

    The following two tables identify the minimum set of NPDES data that 
authorized states, tribes, territories must enter or transfer to EPA's 
national NPDES data system as well as what NPDES-regulated entities must 
electronically report to the designated initial recipient (authorized 
NPDES program or EPA) [see 40 CFR 127.2(b)]. Authorized NPDES programs 
will be the data provider in the event the regulated entity is covered 
by a waiver from electronic reporting. Use of these two tables ensures 
that there is consistent and complete reporting nationwide, and 
expeditious collection and processing of the data, thereby making it 
more accurate and timely. Taken together, these data standardizations 
and the corresponding electronic reporting requirements in 40 CFR parts 
3, 122, 123, 124, 125, 127, 403, and 503 are designed to save the NPDES 
authorized programs considerable resources, make reporting easier for 
NPDES-regulated entities, streamline permit renewals (as permit writers 
typically review previous noncompliance events during permit renewal), 
ensure full exchange of NPDES program data between states and EPA to the 
public, improve environmental decision-making, and protect human health 
and the environment.
    Authorized NPDES programs may also require NPDES regulated entities 
to submit more data than what is listed in this appendix. The authorized 
NPDES program can require NPDES regulated entities to submit these 
``non-appendix A'' data on paper, electronically, or attachments to 
electronic notices and reports filed in compliance with this part.
    Instructions: Table 1 of this appendix provides the list of data 
sources and minimum submission frequencies for the ten different NPDES 
Data Groups. Table 2 of this appendix provides the data that must be 
electronically reported for each of these NPDES Data Groups. The use of 
each data element is determined by identifying the number(s) in the 
column labeled ``NPDES Data Group Number'' in Table 2 and finding the 
corresponding ``NPDES Data Group Number'' in Table 1. For example, a 
value of ``1'' in Table 2 means that this data element is required in 
the electronic transmission of data from the NPDES program to EPA (Core 
NPDES Permitting, Compliance, and Enforcement Data). Likewise, a value 
of ``1 through 10'' in Table 2 means that this data element is required 
in all ten NPDES data groups. NPDES regulated entities that have no 
historical record (e.g., ``greenfield'' facilities) do not need to 
provide data elements that rely on historical data elements. For the 
purposes of this appendix, the term `sewage sludge' [see 40 CFR 
503.9(w)] also refers to the material that is commonly referred to as 
`biosolids.' EPA does not have a regulatory definition for biosolids but 
this material is commonly referred to as sewage sludge that is placed 
on, or applied to the land to use the beneficial properties of the 
material as a soil amendment, conditioner, or fertilizer. EPA's use of 
the term `biosolids' in this appendix is to confirm that information 
about beneficially used sewage sludge (a.k.a. biosolids) is part of the 
data collected in this appendix.

\2\ Use the ``NPDES Data Group Number'' in this table and the ``NPDES Data Group Number'' column in Table 2 of
  this appendix to identify the source of the required data entry. EPA notes that electronic systems may use
  additional data to facilitate electronic reporting as well as management and reporting of electronic data. For
  example, NPDES permittees may be required to enter their NPDES permit number (``NPDES ID''--NPDES Data Group 1
  and 2) into the applicable electronic reporting system in order to identify their permit and submit a
  Discharge Monitoring Report (DMR--NPDES Data Group 3). Additionally, NPDES regulated entities may be required
  to enter and submit data to update or correct erroneous data. For example, NPDES permittees may be required to
  enter new data regarding the Facility Individual First Name and Last Name (NPDES Data Group 1 and 2) with
  their DMR submission when there is a facility personnel change.
\3\ The applicable reporting frequency is specified in the NPDES permit or control mechanism, which may be more
  frequent than the minimum frequency specified in this table.

specified in the standard established for any particular pollutant.
    (d)(1) Upon the compliance date for any section 307(a) toxic 
pollutant effluent standard or prohibition, each owner or operator of a 
discharge subject to such standard or prohibition shall comply with such 
monitoring, sampling, recording, and reporting conditions as the 
Regional Administrator (or State Director, if appropriate) may require 
for that discharge. Notice of such conditions shall be provided in 
writing to the owner or operator.
    (2) In addition to any conditions required pursuant to paragraph 
(d)(1) of this section and to the extent not required in conditions 
contained in NPDES permits, within 60 days following the close of each 
calendar year each owner or operator of a discharge

[[Page 495]]

subject to any toxic standard or prohibition shall report to the 
Regional Administrator (or State Director, if appropriate) concerning 
the compliance of such discharges. Such report shall include, as a 
minimum, information concerning (i) relevant identification of the

Sec. 129.6  Adjustment of effluent standard for presence of toxic
pollutant in the intake water.

    (a) Upon the request of the owner or operator of a facility 
discharging a pollutant subject to a toxic pollutant effluent standard 
or prohibition, the Regional Administrator (or State Director, if 
appropriate) shall give credit, and shall adjust the effluent 
standard(s) in such permit to reflect credit for the toxic pollutant(s) 
in the owner's or operator's water supply if (1) the source of the 
owner's or operator's water supply is the same body of water into which 
the discharge is made and if (2) it is demonstrated to the Regional 
Administrator (or State Director, if appropriate) that the toxic 
pollutant(s) present in the owner's or operator's intake water will not 
be removed by any wastewater treatment systems whose design capacity and 
operation were such as to reduce toxic pollutants to the levels required 
by the applicable toxic pollutant effluent standards in the absence of 
the toxic pollutant in the intake water.
    (b) Effluent limitations established pursuant to this section shall 
be calculated on the basis of the amount of section 307(a) toxic 
pollutant(s) present in the water after any water supply treatment steps 
have been performed by or for the owner or operator.
    (c) Any permit which includes toxic pollutant effluent limitations 
established pursuant to this section shall also contain conditions 
requiring the

[[Page 496]]

permittee to conduct additional monitoring in the manner and locations 
determined by the Regional Administrator (or State Director, if 
appropriate) for those toxic pollutants for which the toxic pollutant 
effluent standards have been adjusted.



Sec. 129.7  Requirement and procedure for establishing a more 
stringent effluent limitation.

    (a) In exceptional cases: (1) Where the Regional Administrator (or 
State Director, if appropriate) determines that the ambient water 
criterion established in these standards is not being met or will not be 
met in the receiving water as a result of one or more discharges at 
levels allowed by these standards, and
    (2) Where he further determines that this is resulting in or may 
cause or contribute to significant adverse effects on aquatic or other 
organisms usually or potentially present, or on human health, he may 
issue to an owner or operator a permit or a permit modification 
containing a toxic pollutant effluent limitation at a more stringent 
level than that required by the standard set forth in these regulations. 
Any such action shall be taken pursuant to the procedural provisions of 
40 CFR parts 124 and 125, as appropriate. In any proceeding in 
connection with such action the burden of proof and of going forward 
with evidence with regard to such more stringent effluent limitation 
shall be upon the Regional Administrator (or State Director, if 
appropriate) as the proponent of such more stringent effluent 
limitation.
    (3) Evidence in such proceeding shall include at a minimum: An 
analysis using data and other information to demonstrate receiving water 
concentrations of the specified toxic pollutant, projections of the 
anticipated effects of the proposed modification on such receiving water 
concentrations, and the hydrologic and hydrographic characteristics of 
the receiving waters including the occurrence of dispersion of the 
effluent. Detailed specifications for presenting relevant information by 
any interested party may be prescribed in guidance documents published 
from time to time, whose availability will be announced in the Federal 
Register.
    (b) Any effluent limitation in an NPDES permit which a State 
proposes to issue which is more stringent than the toxic pollutant 
effluent standards promulgated by the Administrator is subject to review 
by the Administrator under section 402(d) of the Act. The Administrator 
may approve or disapprove such limitation(s) or specify another 
limitation(s) upon review of any record of any proceedings held in 
connection with the permit issuance or modification and any other 
evidence available to him. If he takes no action within ninety days of 
his receipt of the notification of the action of the permit issuing 
authority and any record thereof, the action of the State permit issuing 
authority shall be deemed to be approved.



Sec. 129.8  Compliance date.

    (a) The effluent standards or prohibitions set forth herein shall be 
complied with not later than one year after promulgation unless an 
earlier date is established by the Administrator for an industrial 
subcategory in the promulgation of the standards or prohibitions.
    (b) Toxic pollutant effluent standards or prohibitions set forth 
herein shall become enforceable under sections 307(d) and 309 of the Act 
on the date established in paragraph (a) of this section regardless of 
proceedings in connection with the issuance of any NPDES permit or 
application therefor, or modification or renewal thereof.

water into which the discharge is made. The requirement of paragraph (1) 
of Sec. 129.6(a), relating to the source of the water supply, shall be 
waived, and such facility shall be eligible to apply for a credit under 
Sec. 129.6, upon a showing by the owner or operator of such facility to 
the Regional Administrator (or State Director, if appropriate) that the 
concentration of PCBs in the intake water supply of such facility does 
not exceed

[[Page 503]]

the concentration of PCBs in the receiving water body to which the plant 
discharges its effluent.

Sec. 130.0  Program summary and purpose.

    (a) This subpart establishes policies and program requirements for 
water quality planning, management and implementation under sections 
106, 205(j), non-construction management 205(g), 208, 303 and 305 of the 
Clean Water Act. The Water Quality Management (WQM) process described in 
the Act and in this regulation provides the authority for a consistent 
national approach for maintaining, improving and protecting water 
quality while allowing States to implement the most effective individual 
programs. The process is implemented jointly by EPA, the States, 
interstate agencies, and areawide, local and regional planning 
organizations. This regulation explains the requirements of the Act, 
describes the relationships between the several components of the WQM 
process and outlines the roles of the major participants in the process. 
The components of the WQM process are discussed below.
    (b) Water quality standards (WQS) are the State's goals for 
individual water bodies and provide the legal basis for control 
decisions under the Act. Water quality monitoring activities provide the 
chemical, physical and biological data needed to determine the present 
quality of a State's waters and to identify the sources of pollutants in 
those waters. The primary assessment of the quality of a State's water 
is contained in its biennial Report to Congress required by section 
305(b) of the Act.
    (c) This report and other assessments of water quality are used in 
the State's WQM plans to identify priority water quality problems. These 
plans also contain the results of the State's analyses and management 
decisions which are necessary to control specific sources of pollution. 
The plans recommend control measures and designated management agencies 
(DMAs) to attain the goals established in the State's water quality 
standards.
    (d) These control measures are implemented by issuing permits, 
building publicly-owned treatment works (POTWs), instituting best 
management practices for nonpoint sources of pollution and other means. 
After control measures are in place, the State evaluates the extent of 
the resulting improvements in water quality, conducts additional data 
gathering and planning to determine needed modifications in control 
measures and again institutes control measures.
    (e) This process is a dynamic one, in which requirements and 
emphases vary over time. At present, States have completed WQM plans 
which are generally comprehensive in geographic and programmatic scope. 
Technology based controls are being implemented for most point sources 
of pollution. However, WQS have not been attained in many water bodies 
and are threatened in others.
    (f) Present continuing planning requirements serve to identify these 
critical water bodies, develop plans for achieving higher levels of 
abatement and specify additional control measures. Consequently, this 
regulation reflects a programmatic emphasis on concentrating planning 
and abatement activities on priority water quality

[[Page 504]]

issues and geographic areas. EPA will focus its grant funds on 
activities designed to address these priorities. Annual work programs 
negotiated between EPA and State and interstate agencies will reflect 
this emphasis.



Sec. 130.1  Applicability.

    (a) This subpart applies to all State, eligible Indian Tribe, 
interstate, areawide and regional and local CWA water quality planning 
and management activities undertaken on or after February 11, 1985 
including all updates and continuing certifications for approved Water 
Quality Management (WQM) plans developed under sections 208 and 303 of 
the Act.
    (b) Planning and management activities undertaken prior to February 
11, 1985 are governed by the requirements of the regulations in effect 
at the time of the last grant award.

FR 13817, Mar. 23, 1994]



Sec. 130.2  Definitions.

    (a) The Act. The Clean Water Act, as amended, 33 U.S.C. 1251 et seq.
    (b) Indian Tribe. Any Indian Tribe, band, group, or community 
recognized by the Secretary of the Interior and exercising governmental 
authority over a Federal Indian reservation.
    (c) Pollution. The man-made or man-induced alteration of the 
chemical, physical, biological, and radiological integrity of water.
    (d) Water quality standards (WQS). Provisions of State or Federal 
law which consist of a designated use or uses for the waters of the 
United States and water quality criteria for such waters based upon such 
uses. Water quality standards are to protect the public health or 
welfare, enhance the quality of water and serve the purposes of the Act.
    (e) Load or loading. An amount of matter or thermal energy that is 
introduced into a receiving water; to introduce matter or thermal energy 
into a receiving water. Loading may be either man-caused (pollutant 
loading) or natural (natural background loading).
    (f) Loading capacity. The greatest amount of loading that a water 
can receive without violating water quality standards.
    (g) Load allocation (LA). The portion of a receiving water's loading 
capacity that is attributed either to one of its existing or future 
nonpoint sources of pollution or to natural background sources. Load 
allocations are best estimates of the loading, which may range from 
reasonably accurate estimates to gross allotments, depending on the 
availability of data and appropriate techniques for predicting the 
loading. Wherever possible, natural and nonpoint source loads should be 
distinguished.
    (h) Wasteload allocation (WLA). The portion of a receiving water's 
loading capacity that is allocated to one of its existing or future 
point sources of pollution. WLAs constitute a type of water quality-
based effluent limitation.
    (i) Total maximum daily load (TMDL). The sum of the individual WLAs 
for point sources and LAs for nonpoint sources and natural background. 
If a receiving water has only one point source discharger, the TMDL is 
the sum of that point source WLA plus the LAs for any nonpoint sources 
of pollution and natural background sources, tributaries, or adjacent 
segments. TMDLs can be expressed in terms of either mass per time, 
toxicity, or other appropriate measure. If Best Management Practices 
(BMPs) or other nonpoint source pollution controls make more stringent 
load allocations practicable, then wasteload allocations can be made 
less stringent. Thus, the TMDL process provides for nonpoint source 
control tradeoffs.
    (j) Water quality limited segment. Any segment where it is known 
that water quality does not meet applicable water quality standards, 
and/or is not expected to meet applicable water quality standards, even 
after the application of the technology-based effluent limitations 
required by sections 301(b) and 306 of the Act.
    (k) Water quality management (WQM) plan. A State or areawide waste 
treatment management plan developed and updated in accordance with the 
provisions of sections 205(j), 208 and 303 of the Act and this 
regulation.

[[Page 505]]

    (l) Areawide agency. An agency designated under section 208 of the 
Act, which has responsibilities for WQM planning within a specified area 
of a State.
    (m) Best Management Practice (BMP). Methods, measures or practices 
selected by an agency to meet its nonpoint source control needs. BMPs 
include but are not limited to structural and nonstructural controls and 
operation and maintenance procedures. BMPs can be applied before, during 
and after pollution-producing activities to reduce or eliminate the 
introduction of pollutants into receiving waters.
    (n) Designated management agency (DMA). An agency identified by a 
WQM plan and designated by the Governor to implement specific control 
recommendations.

[50 FR 1779, Jan. 11, 1985, as amended at 54 FR 14359, Apr. 11, 1989]



Sec. 130.3  Water quality standards.

    A water quality standard (WQS) defines the water quality goals of a 
water body, or portion thereof, by designating the use or uses to be 
made of the water and by setting criteria necessary to protect the uses. 
States and EPA adopt WQS to protect public health or welfare, enhance 
the quality of water and serve the purposes of the Clean Water Act 
(CWA). Serve the purposes of Act (as defined in sections 101(a)(2) and 
303(c) of the Act) means that WQS should, wherever attainable, provide 
water quality for the protection and propagation of fish, shellfish and 
wildlife and for recreation in and on the water and take into 
consideration their use and value for public water supplies, propagation 
of fish, shellfish, wildlife, recreation in and on the water, and 
agricultural, industrial and other purposes including navigation.

Such standards serve the dual purposes of establishing the water quality 
goals for a specific water body and serving as the regulatory basis for 
establishment of water quality-based treatment controls and strategies 
beyond the technology-based level of treatment required by sections 
301(b) and 306 of the Act. States shall review and revise WQS in 
accordance with applicable regulations and, as appropriate, update their 
Water Quality Management (WQM) plans to reflect such revisions. Specific 
WQS requirements are found in 40 CFR part 131.



Sec. 130.4  Water quality monitoring.

    (a) In accordance with section 106(e)(1), States must establish 
appropriate monitoring methods and procedures (including biological 
monitoring) necessary to compile and analyze data on the quality of 
waters of the United States and, to the extent practicable, ground-
waters. This requirement need not be met by Indian Tribes. However, any 
monitoring and/or analysis activities undertaken by a Tribe must be 
performed in accordance with EPA's quality assurance/quality control 
guidance.
    (b) The State's water monitoring program shall include collection 
and analysis of physical, chemical and biological data and quality 
assurance and control programs to assure scientifically valid data. The 
uses of these data include determining abatement and control priorities; 
developing and reviewing water quality standards, total maximum daily 
loads, wasteload allocations and load allocations; assessing compliance 
with National Pollutant Discharge Elimination System (NPDES) permits by 
dischargers; reporting information to the public through the section 
305(b) report and reviewing site-specific monitoring efforts.

[50 FR 1779, Jan. 11, 1985, as amended at 54 FR 14359, Apr. 11, 1989]



Sec. 130.5  Continuing planning process.

    (a) General. Each State shall establish and maintain a continuing 
planning process (CPP) as described under section 303(e)(3)(A)-(H) of 
the Act. Each State is responsible for managing its water quality 
program to implement the processes specified in the continuing planning 
process. EPA is responsible for periodically reviewing the adequacy of 
the State's CPP.
    (b) Content. The State may determine the format of its CPP as long 
as the mininum requirements of the CWA and this regulation are met. The 
following processes must be described in each State CPP, and the State 
may include other processes at its discretion.

[[Page 506]]

    (1) The process for developing effluent limitations and schedules of 
compliance at least as stringent as those required by sections 301(b) 
(1) and (2), 306 and 307, and at least stringent as any requirements 
contained in applicable water quality standards in effect under 
authority of section 303 of the Act.
    (2) The process for incorporating elements of any applicable 
areawide waste treatment plans under section 208, and applicable basin 
plans under section 209 of the Act.
    (3) The process for developing total maximum daily loads (TMDLs) and 
individual water quality based effluent limitations for pollutants in 
accordance with section 303(d) of the Act and Sec. 130.7(a) of this 
regulation.
    (4) The process for updating and maintaining Water Quality 
Management (WQM) plans, including schedules for revision.
    (5) The process for assuring adequate authority for 
intergovernmental cooperation in the implementation of the State WQM 
program.
    (6) The process for establishing and assuring adequate 
implementation of new or revised water quality standards, including 
schedules of compliance, under section 303(c) of the Act.
    (7) The process for assuring adequate controls over the disposition 
of all residual waste from any water treatment processing.
    (8) The process for developing an inventory and ranking, in order of 
priority of needs for construction of waste treatment works required to 
meet the applicable requirements of sections 301 and 302 of the Act.
    (9) The process for determining the priority of permit issuance.
    (c) Regional Administrator review. The Regional Administrator shall 
review approved State CPPs from time to time to ensure that the planning 
processes are consistent with the Act and this regulation. The Regional 
Administrator shall not approve any permit program under Title IV of the 
Act for any State which does not have an approved continuing planning 
process.



Sec. 130.6  Water quality management plans.

    (a) Water quality management (WQM) plans. WQM plans consist of 
initial plans produced in accordance with sections 208 and 303(e) of the 
Act and certified and approved updates to those plans. Continuing water 
quality planning shall be based upon WQM plans and water quality 
problems identified in the latest 305(b) reports. State water quality 
planning should focus annually on priority issues and geographic areas 
and on the development of water quality controls leading to 
implementation measures. Water quality planning directed at the removal 
of conditions placed on previously certified and approved WQM plans 
should focus on removal of conditions which will lead to control 
decisions.
    (b) Use of WQM plans. WQM plans are used to direct implementation. 
WQM plans draw upon the water quality assessments to identify priority 
point and nonpoint water quality problems, consider alternative 
solutions and recommend control measures, including the financial and 
institutional measures necessary for implementing recommended solutions. 
State annual work programs shall be based upon the priority issues 
identified in the State WQM plan.
    (c) WQM plan elements. Sections 205(j), 208 and 303 of the Act 
specify water quality planning requirements. The following plan elements 
shall be included in the WQM plan or referenced as part of the WQM plan 
if contained in separate documents when they are needed to address water 
quality problems.
    (1) Total maximum daily loads. TMDLs in accordance with sections 
303(d) and (e)(3)(C) of the Act and Sec. 130.7 of this part.
    (2) Effluent limitations. Effluent limitations including water 
quality based effluent limitations and schedules of compliance in 
accordance with section 303(e)(3)(A) of the Act and Sec. 130.5 of this 
part.
    (3) Municipal and industrial waste treatment. Identification of 
anticipated municipal and industrial waste treatment works, including 
facilities for treatment of stormwater-induced combined sewer overflows; 
programs to

[[Page 507]]

provide necessary financial arrangements for such works; establishment 
of construction priorities and schedules for initiation and completion 
of such treatment works including an identification of open space and 
recreation opportunities from improved water quality in accordance with 
section 208(b)(2) (A) and (B) of the Act.
    (4) Nonpoint source management and control. (i) The plan shall 
describe the regulatory and non-regulatory programs, activities and Best 
Management Practices (BMPs) which the agency has selected as the means 
to control nonpoint source pollution where necessary to protect or 
achieve approved water uses. Economic, institutional, and technical 
factors shall be considered in a continuing process of identifying 
control needs and evaluating and modifying the BMPs as necessary to 
achieve water quality goals.
    (ii) Regulatory programs shall be identified where they are 
determined to be necessary by the State to attain or maintain an 
approved water use or where non-regulatory approaches are inappropriate 
in accomplishing that objective.
    (iii) BMPs shall be identified for the nonpoint sources identified 
in section 208(b)(2)(F)-(K) of the Act and other nonpoint sources as 
follows:
    (A) Residual waste. Identification of a process to control the 
disposition of all residual waste in the area which could affect water 
quality in accordance with section 208(b)(2)(J) of the Act.
    (B) Land disposal. Identification of a process to control the 
disposal of pollutants on land or in subsurface excavations to protect 
ground and surface water quality in accordance with section 208(b)(2)(K)

208(b)(2)(K) of the Act. States are not required to develop ground-water 
WQM plan elements beyond the requirements of section 208(b)(2)(K) of the 
Act, but may develop a ground-water plan element if they determine it is 
necessary to address a

[[Page 508]]

ground-water quality problem. If a State chooses to develop a ground-
water plan element, it should describe the essentials of a State program 
and should include, but is not limited to:
    (i) Overall goals, policies and legislative authorities for 
protection of ground-water.
    (ii) Monitoring and resource assessment programs in accordance with 
section 106(e)(1) of the Act.
    (iii) Programs to control sources of contamination of ground-water 
including Federal programs delegated to the State and additional 
programs authorized in State statutes.
    (iv) Procedures for coordination of ground-water protection programs

provision of program financing, training and technical assistance, 
public participation, and emergency management.
    (d) Indian Tribes. An Indian Tribe is eligible for the purposes of 
this rule and the Clean Water Act assistance programs under 40 CFR part 
35, subparts A and H if:
    (1) The Indian Tribe has a governing body carrying out substantial 
governmental duties and powers;
    (2) The functions to be exercised by the Indian Tribe pertain to the 
management and protection of water resources which are held by an Indian 
Tribe, held by the United States in trust for Indians, held by a member 
of an Indian Tribe if such property interest is subject to a trust 
restriction on alienation, or otherwise within the borders of an Indian 
reservation; and
    (3) The Indian Tribe is reasonably expected to be capable, in the 
Regional Administrator's judgment, of carrying out the functions to be 
exercised in a manner consistent with the terms and purposes of the 
Clean Water Act and applicable regulations.
    (e) Update and certification. State and/or areawide agency WQM plans 
shall be updated as needed to reflect changing water quality conditions, 
results of implementation actions, new requirements or to remove 
conditions in prior conditional or partial plan approvals. Regional 
Administrators may require that State WQM plans be updated as needed. 
State Continuing Planning Processes (CPPs) shall specify the process and 
schedule used to revise WQM plans. The State shall ensure that State and 
areawide WQM plans together include all necessary plan elements and that 
such plans are consistent with one another. The Governor or the 
Governor's designee shall certify by letter to the Regional 
Administrator for EPA approval that WQM plan updates are consistent with 
all other parts of the plan. The certification may be contained in the 
annual State work program.

Sec. 130.7  Total maximum daily loads (TMDL) and individual water
quality-based effluent limitations.

    (a) General. The process for identifying water quality limited 
segments still requiring wasteload allocations, load allocations and 
total maximum daily loads (WLAs/LAs and TMDLs), setting priorities for 
developing these loads; establishing these loads for segments 
identified, including water quality monitoring, modeling, data analysis, 
calculation methods, and list of pollutants to be regulated; submitting 
the State's list of segments identified, priority ranking, and loads 
established (WLAs/LAs/TMDLs) to EPA for approval; incorporating the 
approved loads into the State's WQM plans and NPDES permits; and 
involving the public, affected dischargers, designated areawide 
agencies, and local governments in this process shall be clearly 
described in the State Continuing Planning Process (CPP).
    (b) Identification and priority setting for water quality-limited 
segments still requiring TMDLs.
    (1) Each State shall identify those water quality-limited segments 
still requiring TMDLs within its boundaries for which:

[[Page 509]]

    (i) Technology-based effluent limitations required by sections 
301(b), 306, 307, or other sections of the Act;
    (ii) More stringent effluent limitations (including prohibitions) 
required by either State or local authority preserved by section 510 of 
the Act, or Federal authority (law, regulation, or treaty); and
    (iii) Other pollution control requirements (e.g., best management 
practices) required by local, State, or Federal authority are not 
stringent enough to implement any water quality standards (WQS) 
applicable to such waters.
    (2) Each State shall also identify on the same list developed under 
paragraph (b)(1) of this section those water quality-limited segments 
still requiring TMDLs or parts thereof within its boundaries for which 
controls on thermal discharges under section 301 or State or local 
requirements are not stringent enough to assure protection and 
propagation of a balanced indigenous population of shellfish, fish and 
wildlife.
    (3) For the purposes of listing waters under Sec. 130.7(b), the 
term ``water quality standard applicable to such waters'' and 
``applicable water quality standards'' refer to those water quality 
standards established under section 303 of the Act, including numeric 
criteria, narrative criteria, waterbody uses, and antidegradation 
requirements.
    (4) The list required under Sec. Sec. 130.7(b)(1) and 130.7(b)(2) 
of this section shall include a priority ranking for all listed water 
quality-limited segments still requiring TMDLs, taking into account the 
severity of the pollution and the uses to be made of such waters and 
shall identify the pollutants causing or expected to cause violations of 
the applicable water quality standards. The priority ranking shall 
specifically include the identification of waters targeted for TMDL 
development in the next two years.
    (5) Each State shall assemble and evaluate all existing and readily 
available water quality-related data and information to develop the list 
required by Sec. Sec. 130.7(b)(1) and 130.7(b)(2). At a minimum ``all 
existing and readily available water quality-related data and 
information'' includes but is not limited to all of the existing and 
readily available data and information about the following categories of 
waters:
    (i) Waters identified by the State in its most recent section 305(b) 
report as ``partially meeting'' or ``not meeting'' designated uses or as 
``threatened'';
    (ii) Waters for which dilution calculations or predictive models 
indicate nonattainment of applicable water quality standards;
    (iii) Waters for which water quality problems have been reported by 
local, state, or federal agencies; members of the public; or academic 
institutions. These organizations and groups should be actively 
solicited for research they may be conducting or reporting. For example, 
university researchers, the United States Department of Agriculture, the 
National Oceanic and Atmospheric Administration, the United States 
Geological Survey, and the United States Fish and Wildlife Service are 
good sources of field data; and
    (iv) Waters identified by the State as impaired or threatened in a 
nonpoint assessment submitted to EPA under section 319 of the CWA or in 
any updates of the assessment.
    (6) Each State shall provide documentation to the Regional 
Administrator to support the State's determination to list or not to 
list its waters as required by Sec. Sec. 130.7(b)(1) and 130.7(b)(2). 
This documentation shall be submitted to the Regional Administrator 
together with the list required by Sec. Sec. 130.7(b)(1) and 
130.7(b)(2) and shall include at a minimum:
    (i) A description of the methodology used to develop the list; and
    (ii) A description of the data and information used to identify 
waters, including a description of the data and information used by the 
State as required by Sec. 130.7(b)(5); and
    (iii) A rationale for any decision to not use any existing and 
readily available data and information for any one of the categories of 
waters as described in Sec. 130.7(b)(5); and
    (iv) Any other reasonable information requested by the Regional 
Administrator. Upon request by the Regional Administrator, each State 
must demonstrate good cause for not including a water or waters on the 
list. Good cause

[[Page 510]]

includes, but is not limited to, more recent or accurate data; more 
sophisticated water quality modeling; flaws in the original analysis 
that led to the water being listed in the categories in Sec. 
130.7(b)(5); or changes in conditions, e.g., new control equipment, or 
elimination of discharges.
    (c) Development of TMDLs and individual water quality based effluent 
limitations.
    (1) Each State shall establish TMDLs for the water quality limited 
segments identified in paragraph (b)(1) of this section, and in 
accordance with the priority ranking. For pollutants other than heat, 
TMDLs shall be established at levels necessary to attain and maintain 
the applicable narrative and numerical WQS with seasonal variations and 
a margin of safety which takes into account any lack of knowledge 
concerning the relationship between effluent limitations and water 
quality. Determinations of TMDLs shall take into account critical 
conditions for stream flow, loading, and water quality parameters.
    (i) TMDLs may be established using a pollutant-by-pollutant or 
biomonitoring approach. In many cases both techniques may be needed. 
Site-specific information should be used wherever possible.
    (ii) TMDLs shall be established for all pollutants preventing or 
expected to prevent attainment of water quality standards as identified 
pursuant to paragraph (b)(1) of this section. Calculations to establish 
TMDLs shall be subject to public review as defined in the State CPP.
    (2) Each State shall estimate for the water quality limited segments 
still requiring TMDLs identified in paragraph (b)(2) of this section, 
the total maximum daily thermal load which cannot be exceeded in order 
to assure protection and propagation of a balanced, indigenous 
population of shellfish, fish and wildlife. Such estimates shall take 
into account the normal water temperatures, flow rates, seasonal 
variations, existing sources of heat input, and the dissipative capacity 
of the identified waters or parts thereof. Such estimates shall include 
a calculation of the maximum heat input that can be made into each such 
part and shall include a margin of safety which takes into account any 
lack of knowledge concerning the development of thermal water quality 
criteria for protection and propagation of a balanced, indigenous 
population of shellfish, fish and wildlife in the identified waters or 
parts thereof.
    (d) Submission and EPA approval. (1) Each State shall submit 
biennially to the Regional Administrator beginning in 1992 the list of 
waters, pollutants causing impairment, and the priority ranking 
including waters targeted for TMDL development within the next two years 
as required under paragraph (b) of this section. For the 1992 biennial 
submission, these lists are due no later than October 22, 1992. 
Thereafter, each State shall submit to EPA lists required under 
paragraph (b) of this section on April 1 of every even-numbered year. 
For the year 2000 submission, a State must submit a list required under 
paragraph (b) of this section only if a court order or consent decree, 
or commitment in a settlement agreement dated prior to January 1, 2000, 
expressly requires EPA to take action related to that State's year 2000 
list. For the year 2002 submission, a State must submit a list required 
under paragraph (b) of this section by October 1, 2002, unless a court 
order, consent decree or commitment in a settlement agreement expressly 
requires EPA to take an action related to that State's 2002 list prior 
to October 1, 2002, in which case, the State must submit a list by April 
1, 2002. The list of waters may be submitted as part of the State's 
biennial water quality report required by Sec. 130.8 of this part and 
section 305(b) of the CWA or submitted under separate cover. All WLAs/
LAs and TMDLs established under paragraph (c) for water quality limited 
segments shall continue to be submitted to EPA for review and approval. 
Schedules for submission of TMDLs shall be determined by the Regional 
Administrator and the State.
    (2) The Regional Administrator shall either approve or disapprove 
such listing and loadings not later than 30 days after the date of 
submission. The Regional Administrator shall approve a list developed 
under Sec. 130.7(b) that is submitted after the effective date of

[[Page 511]]

this rule only if it meets the requirements of Sec. 130.7(b). If the 
Regional Administrator approves such listing and loadings, the State 
shall incorporate them into its current WQM plan. If the Regional 
Administrator disapproves such listing and loadings, he shall, not later 
than 30 days after the date of such disapproval, identify such waters in 
such State and establish such loads for such waters as determined 
necessary to implement applicable WQS. The Regional Administrator shall 
promptly issue a public notice seeking comment on such listing and 
loadings. After considering public comment and making any revisions he 
deems appropriate, the Regional Administrator shall transmit the listing 
and loads to the State, which shall incorporate them into its current 
WQM plan.
    (e) For the specific purpose of developing information and as 
resources allow, each State shall identify all segments within its 
boundaries which it has not identified under paragraph (b) of this 
section and estimate for such waters the TMDLs with seasonal variations 
and margins of safety, for those pollutants which the Regional 
Administrator identifies under section 304(a)(2) as suitable for such 
calculation and for thermal discharges, at a level that would assure 
protection and propagation of a balanced indigenous population of fish, 
shellfish and wildlife. However, there is no requirement for such loads 
to be submitted to EPA for approval, and establishing TMDLs for those 
waters identified in paragraph (b) of this section shall be given higher 
priority.

Sec. 130.8  Water quality report.

    (a) Each State shall prepare and submit biennially to the Regional 
Administrator a water quality report in accordance with section 305(b) 
of the Act. The water quality report serves as the primary assessment of 
State water quality. Based upon the water quality data and problems 
identified in the 305(b) report, States develop water quality management 
(WQM) plan elements to help direct all subsequent control activities. 
Water quality problems identified in the 305(b) report should be 
analyzed through water quality management planning leading to the 
development of alternative controls and procedures for problems 
identified in the latest 305(b) report. States may also use the 305(b) 
report to describe ground-water quality and to guide development of 
ground-water plans and programs. Water quality problems identified in 
the 305(b) report should be emphasized and reflected in the State's WQM 
plan and annual work program under sections 106 and 205(j) of the Clean 
Water Act.
    (b) Each such report shall include but is not limited to the 
following:
    (1) A description of the water quality of all waters of the United 
States and the extent to which the quality of waters provides for the 
protection and propagation of a balanced population of shellfish, fish, 
and wildlife and allows recreational activities in and on the water.
    (2) An estimate of the extent to which CWA control programs have 
improved water quality or will improve water quality for the purposes of 
paragraph (b)(1) of this section, and recommendations for future actions 
necessary and identifications of waters needing action.
    (3) An estimate of the environmental, economic and social costs and 
benefits needed to achieve the objectives of the CWA and an estimate of 
the date of such achievement.
    (4) A description of the nature and extent of nonpoint source 
pollution and recommendations of programs needed to control each 
category of nonpoint sources, including an estimate of implementation 
costs.
    (5) An assessment of the water quality of all publicly owned lakes, 
including the status and trends of such water quality as specified in 
section 314(a)(1) of the Clean Water Act.
    (c) States may include a description of the nature and extent of 
ground-water pollution and recommendations of State plans or programs 
needed to maintain or improve ground-water quality.
    (d) In the years in which it is prepared the biennial section 305(b) 
report satisfies the requirement for the annual water quality report 
under section

[[Page 512]]

205(j). In years when the 305(b) report is not required, the State may 
satisfy the annual section 205(j) report requirement by certifying that 
the most recently submitted section 305(b) report is current or by 
supplying an update of the sections of the most recently submitted 
section 305(b) report which require updating.

[50 FR 1779, Jan. 11, 1985, as amended at 57 FR 33050, July 24, 1992]



Sec. 130.9  Designation and de-designation.

    (a) Designation. Areawide planning agencies may be designated by the 
Governor in accordance with section 208(a) (2) and (3) of the Act or may 
self-designate in accordance with section 208(a)(4) of the Act. Such 
designations shall subject to EPA approval in accordance with section 
208(a)(7) of the Act.
    (b) De-designation. The Governor may modify or withdraw the planning 
designation of a designated planning agency other than an Indian tribal 
organization self-designated Sec. 130.6(c)(2) if:
    (1) The areawide agency requests such cancellation; or
    (2) The areawide agency fails to meet its planning requirements as 
specified in grant agreements, contracts or memoranda of understanding; 
or
    (3) The areawide agency no longer has the resources or the 
commitment to continue water quality planning activities within the 
designated boundaries.
    (c) Impact of de-designation. Once an areawide planning agency's 
designation has been withdrawn the State agency shall assume direct 
responsibility for continued water quality planning and oversight of 
implementation within the area.
    (d) Designated management agencies (DMA). In accordance with section 
208(c)(1) of the Act, management agencies shall be designated by the 
Governor in consultation with the designated planning agency. EPA shall 
approve such designations unless the DMA lacks the legal, financial and 
managerial authority required under section 208(c)(2) of the Act. 
Designated management agencies shall carry out responsibilities 
specified in Water Quality Management (WQM) plans. Areawide planning 
agencies shall monitor DMA activities in their area and recommend 
necessary plan changes during the WQM plan update. Where there is no 
designated areawide planning agency, States shall monitor DMA activities 
and make any necessary changes during the WQM plan update.



Sec. 130.10  State submittals to EPA.

    (a) The following must be submitted regularly by the States to EPA:
    (1) The section 305(b) report, in FY 84 and every two years 
thereafter, and the annual section 205(j) certification or update of the 
305(b) water quality report; (Approved by OMB under the control number 
2040-0071)
    (2) The annual State work program(s) under sections 106 and 205(j) 
of the Act; and (Approved by OMB under the control number 2010-0004)
    (3) Revisions or additions to water quality standards (WQS) 
(303(c)). (Approved by OMB under 2040-0049)
    (b) The Act also requires that each State initially submit to EPA 
and revise as necessary the following:
    (1) Continuing planning process (CPP) (303(e));
    (2) Identification of water quality-limited waters still requiring 
TMDLs (section 303(d)), pollutants, and the priority ranking including 
waters targeted for TMDL development within the next two years as 
required under Sec. 130.7(b) in accordance with the schedule set for in 
Sec. 130.7(d)(1).

(Approved by the Office of Management and Budget under control number 
2040-0071)
    (3) Total maximum daily loads (TMDLs) (303(d)); and
    (4) Water quality management (WQM) plan and certified and approved 
WQM plan updates (208, 303(e)). (Paragraph (b)(1), (4) approved by OMB 
under the control number 2010-0004).
    (c) The form and content of required State submittals to EPA may be 
tailored to reflect the organization and needs of the State, as long as 
the requirements and purposes of the Act, this part and, where 
applicable, 40 CFR parts 29, 30, 33 and 35, subparts A and J are met. 
The need for revision and schedule of submittals shall be agreed to 
annually with EPA as the States annual work program is developed.

[[Page 513]]

    (d) Not later than February 4, 1989, each State shall submit to EPA 
for review, approval, and implementation--
    (1) A list of those waters within the State which after the 
application of effluent limitations required under section 301(b)(2) of 
the CWA cannot reasonably be anticipated to attain or maintain (i) water 
quality standards for such waters reviewed, revised, or adopted in 
accordance with section 303(c)(2)(B) of the CWA, due to toxic 
pollutants, or (ii) that water quality which shall assure protection of 
public health, public water supplies, agricultural and industrial uses, 
and the protection and propagation of a balanced population of 
shellfish, fish and wildlife, and allow recreational activities in and 
on the water;
    (2) A list of all navigable waters in such State for which the State 
does not expect the applicable standard under section 303 of the CWA 
will be achieved after the requirements of sections 301(b), 306, and 
307(b) are met, due entirely or substantially to discharges from point 
sources of any toxic pollutants listed pursuant to section 307(a);
    (3) For each segment of navigable waters included on such lists, a 
determination of the specific point source discharging any such toxic 
pollutant which is believed to be preventing or impairing such water 
quality and the amount of each such toxic pollutant discharged by each 
such source.

(Approved by the Office of Management and Budget under control number 
2040-0152)
    (4) For the purposes of listing waters under Sec. 130.10(d)(2), 
applicable standard means a numeric criterion for a priority pollutant 
promulgated as part of a state water quality standard. Where a state 
numeric criterion for a priority pollutant is not promulgated as part of 
a state water quality standard, for the purposes of listing waters 
``applicable standard'' means the state narrative water quality 
criterion to control a priority pollutant (e.g., no toxics in toxic 
amounts) interpreted on a chemical-by-chemical basis by applying a 
proposed state cirterion, an explicit state policy or regulation, or an 
EPA national water quality criterion, supplemented with other relevant 
information.
    (5) If a water meets either of the two conditions listed below the 
water must be listed under Sec. 130.10(d)(2) on the grounds that the 
applicable standard is not achieved or expected to be achieved due 
entirely or substantially to discharges from point sources.
    (i) Existing or additional water quality-based limits on one or more 
point sources would result in the achievement of an applicable water 
quality standard for a toxic pollutant; or
    (ii) The discharge of a toxic pollutant from one or more point 
sources, regardless of any nonpoint source contribution of the same 
pollutant, is sufficient to cause or is expected to cause an excursion 
above the applicable water quality standard for the toxic pollutant.
    (6) Each state shall assemble and evaluate all existing and readily 
available water quality-related data and information and each state 
shall develop the lists required by paragraphs (d)(1), (2), and (3) of 
this section based upon this data and information. At a minimum, all 
existing and readily available water quality-related data and 
information includes, but is not limited to, all of the existing and 
readily available data about the following categories of waters in the 
state:
    (i) Waters where fishing or shellfish bans and/or advisories are 
currently in effect or are anticipated.
    (ii) Waters where there have been repeated fishkills or where 
abnormalities (cancers, lesions, tumors, etc.) have been observed in 
fish or other aquatic life during the last ten years.
    (iii) Waters where there are restrictions on water sports or 
recreational contact.
    (iv) Waters identified by the state in its most recent state section 
305(b) report as either ``partially achieving'' or ``not achieving'' 
designated uses.
    (v) Waters identified by the states under section 303(d) of the CWA 
as waters needing water quality-based controls.
    (vi) Waters identified by the state as priority waterbodies. (State 
Water Quality Management plans often include priority waterbody lists 
which are those waters that most need water pollution control decisions 
to achieve water quality standards or goals.)

[[Page 514]]

    (vii) Waters where ambient data indicate potential or actual 
exceedances of water quality criteria due to toxic pollutants from an 
industry classified as a primary industry in appendix A of 40 CFR part 
122.
    (viii) Waters for which effluent toxicity test results indicate 
possible or actual exceedances of state water quality standards, 
including narrative ``free from'' water quality criteria or EPA water 
quality criteria where state criteria are not available.
    (ix) Waters with primary industrial major dischargers where dilution 
analyses indicate exceedances of state narrative or numeric water 
quality criteria (or EPA water quality criteria where state standards 
are not available) for toxic pollutants, ammonia, or chlorine. These 
dilution analyses must be based on estimates of discharge levels derived 
from effluent guidelines development documents, NPDES permits or permit 
application data (e.g., Form 2C), Discharge Monitoring Reports (DMRs), 
or other available information.
    (x) Waters with POTW dischargers requiring local pretreatment 
programs where dilution analyses indicate exceedances of state water 
quality criteria (or EPA water quality criteria where state water 
quality criteria are not available) for toxic pollutants, ammonia, or 
chlorine. These dilution analyses must be based upon data from NPDES 
permits or permit applications (e.g., Form 2C), Discharge Monitoring 
Reports (DMRs), or other available information.
    (xi) Waters with facilities not included in the previous two 
categories such as major POTWs, and industrial minor dischargers where 
dilution analyses indicate exceedances of numeric or narrative state 
water quality criteria (or EPA water quality criteria where state water 
quality criteria are not available) for toxic pollutants, ammonia, or 
chlorine. These dilution analyses must be based upon estimates of 
discharge levels derived from effluent guideline development documents, 
NPDES permits or permit application data, Discharge Monitoring Reports 
(DMRs), or other available information.
    (xii) Waters classified for uses that will not support the 
``fishable/swimmable'' goals of the Clean Water Act.
    (xiii) Waters where ambient toxicity or adverse water quality 
conditions have been reported by local, state, EPA or other Federal 
Agencies, the private sector, public interest groups, or universities. 
These organizations and groups should be actively solicited for research 
they may be conducting or reporting. For example, university 
researchers, the United States Department of Agriculture, the National 
Oceanic and Atmospheric Administration, the United States Geological 
Survey, and the United States Fish and Wildlife Service are good sources 
of field data and research.
    (xiv) Waters identified by the state as impaired in its most recent 
Clean Lake Assessments conducted under section 314 of the Clean Water 
Act.
    (xv) Waters identified as impaired by nonpoint sources in the 
America's Clean Water: The States' Nonpoint Source Assessments 1985 
(Association of State and Interstate Water Pollution Control 
Administrators (ASIWPCA)) or waters identified as impaired or threatened 
in a nonpoint source assessment submitted by the state to EPA under 
section 319 of the Clean Water Act.
    (xvi) Surface waters impaired by pollutants from hazardous waste 
sites on the National Priority List prepared under section 105(8)(A) of 
CERCLA.
    (7) Each state shall provide documentation to the Regional 
Administrator to support the state's determination to list or not to 
list waters as required by paragraphs (d)(1), (d)(2) and (d)(3) of this 
section. This documentation shall be submitted to the Regional 
Administrator together with the lists required by paragraphs (d)(1), 
(d)(2), and (d)(3) of this section and shall include as a minimum:
    (i) A description of the methodology used to develop each list;
    (ii) A description of the data and information used to identify 
waters and sources including a description of the data and information 
used by the state as required by paragraph (d)(6) of this section;

[[Page 515]]

    (iii) A rationale for any decision not to use any one of the 
categories of existing and readily available data required by paragraph 
(d)(6) of this section; and
    (iv) Any other information requested by the Regional Administrator 
that is reasonable or necessary to determine the adequacy of a state's 
lists. Upon request by the Regional Administrator, each state must 
demonstrate good cause for not including a water or waters on one or 
more lists. Good cause includes, but is not limited to, more recent or 
accurate data; more accurate water quality modeling; flaws in the 
original analysis that led to the water being identified in a category 
in Sec. 130.10(d)(6); or changes in conditions, e.g., new control 
equipment, or elimination of discharges.
    (8) The Regional Administrator shall approve or disapprove each list 
required by paragraphs (d)(1), (d)(2), and (d)(3) of this section no 
later than June 4, 1989. The Regional Administrator shall approve each 
list required under paragraphs (d)(1), (d)(2), and (d)(3) of this 
section only if it meets the regulatory requirements for listing under 
paragraphs (d)(1), (d)(2), and (d)(3) of this section and if the state 
has met all the requirements of paragraphs (d)(6) and (d)(7) of this 
section.
    (9) If a state fails to submit lists in accordance with paragraph 
(d) of this section or the Regional Administrator does not approve the 
lists submitted by such state in accordance with this paragraph, then 
not later than June 4, 1990, the Regional Administrator, in cooperation 
with such state, shall implement the requirements of CWA section 304(l) 
(1) and (2) in such state.
    (10) If the Regional Administrator disapproves a state's decision 
with respect to one or more of the waters required under paragraph (d) 
(1), (2), or (3) of this section, or one or more of the individual 
control strategies required pursuant to section 304(l)(1)(D), then not 
later than June 4, 1989, the Regional Administrator shall distribute the 
notice of approval or disapproval given under this paragraph to the 
appropriate state Director. The Regional Administrator shall also 
publish a notice of availability, in a daily or weekly newspaper with 
state-wide circulation or in the Federal Register, for the notice of 
approval or disapproval. The Regional Administrator shall also provide 
written notice to each discharger identified under section 304(l)(1)(C), 
that EPA has listed the discharger under section 304(l)(1)(C). The 
notice of approval and disapproval shall include the following:
    (i) The name and address of the EPA office that reviews the state's 
submittals.
    (ii) A brief description of the section 304(l) process.
    (iii) A list of waters, point sources and pollutants disapproved 
under this paragraph.
    (iv) If the Regional Administrator determines that a state did not 
provide adequate public notice and an opportunity to comment on the 
lists prepared under this section, or if the Regional Administrator 
chooses to exercise his or her discretion, a list of waters, point 
sources, or pollutants approved under this paragraph.
    (v) The name, address, and telephone number of the person at the 
Regional Office from whom interested persons may obtain more 
information.
    (vi) Notice that written petitions or comments are due within 120 
days.
    (11) As soon as practicable, but not later than June 4, 1990, the 
Regional Office shall issue a response to petitions or comments received 
under paragraph (d)(10) of this section. Notice shall be given in the 
same manner as notice described in paragraph (d)(10) of this section, 
except for the following changes to the notice of approvals and 
disapprovals:
    (i) The lists of waters, point sources and pollutants must reflect 
any changes made pursuant to comments or petitions received.
    (ii) A brief description of the subsequent steps in the section 
304(l) process shall be included.

Sec. 130.11  Program management.

    (a) State agencies may apply for grants under sections 106, 205(j) 
and 205(g) to carry out water quality planning and management 
activities. Interstate agencies may apply for grants

[[Page 516]]

under section 106 to carry out water quality planning and management 
activities. Local or regional planning organizations may request 106 and 
205(j) funds from a State for planning and management activities. Grant 
administrative requirements for these funds appear in 40 CFR parts 25, 
29, 30, 33 and 35, subparts A and J.
    (b) Grants under section 106 may be used to fund a wide range of 
activities, including but not limited to assessments of water quality, 
revision of water quality standards (WQS), development of alternative 
approaches to control pollution, implementation and enforcement of 
control measures and development or implementation of ground water 
programs. Grants under section 205(j) may be used to fund water quality 
management (WQM) planning activities but may not be used to fund 
implementation of control measures (see part 35, subpart A). Section 
205(g) funds are used primarily to manage the wastewater treatment works 
construction grants program pursuant to the provisions of 40 CFR part 
35, subpart J. A State may also use part of the 205(g) funds to 
administer approved permit programs under sections 402 and 404, to 
administer a statewide waste treatment management program under section 
208(b)(4) and to manage waste treatment construction grants for small 
communities.
    (c) Grant work programs for water quality planning and management 
shall describe geographic and functional priorities for use of grant 
funds in a manner which will facilitate EPA review of the grant 
application and subsequent evaluation of work accomplished with the 
grant funds. A State's 305(b) Report, WQM plan and other water quality 
assessments shall identify the State's priority water quality problems 
and areas. The WQM plan shall contain an analysis of alternative control 
measures and recommendations to control specific problems. Work programs 
shall specify the activities to be carried out during the period of the 
grant; the cost of specific activities; the outputs, for example, 
permits issued, intensive surveys, wasteload allocations, to be produced 
by each activity; and where applicable, schedules indicating when 
activities are to be completed.
    (d) State work programs under sections 106, 205(j) and 205(g) shall 
be coordinated in a manner which indicates the funding from these grants 
dedicated to major functions, such as permitting, enforcement, 
monitoring, planning and standards, nonpoint source implementation, 
management of construction grants, operation and maintenance of 
treatment works, ground-water, emergency response and program 
management. States shall also describe how the activities funded by 
these grants are used in a coordinated manner to address the priority 
water quality problems identified in the State's water quality 
assessment under section 305(b).
    (e) EPA, States, areawide agencies, interstate agencies, local and 
Regional governments, and designated management agencies (DMAs) are 
joint participants in the water pollution control program. States may 
enter into contractual arrangements or intergovernmental agreements with 
other agencies concerning the performance of water quality planning and 
management tasks. Such arrangements shall reflect the capabilities of 
the respective agencies and shall efficiently utilize available funds 
and funding eligibilities to meet Federal requirements commensurate with 
State and local priorities. State work programs under section 205(j) 
shall be developed jointly with local, Regional and other comprehensive 
planning organizations.



Sec. 130.12  Coordination with other programs.

    (a) Relationship to the National Pollutant Discharge Elimination 
System (NPDES) program. In accordance with section 208(e) of the Act, no 
NPDES permit may be issued which is in conflict with an approved Water 
Quality Management (WQM) plan. Where a State has assumed responsibility 
for the administration of the permit program under section 402, it shall 
assure consistency with the WQM plan.
    (b) Relationship to the municipal construction grants program. In 
accordance with sections 205(j), 216 and 303(e)(3)(H) of the Act, each 
State shall develop a system for setting priorities

[[Page 517]]

for funding construction of municipal wastewater treatment facilities 
under section 201 of the Act. The State, or the agency to which the 
State has delegated WQM planning functions, shall review each facility 
plan in its area for consistency with the approved WQM plan. Under 
section 208(d) of the Act, after a waste treatment management agency has 
been designated and a WQM plan approved, section 201 construction grant 
funds may be awarded only to those agencies for construction of 
treatment works in conformity with the approved WQM plan.
    (c) Relationship to Federal activities--Each department, agency or 
instrumentality of the executive, legislative and judicial branches of 
the Federal Government having jurisdiction over any property or facility 
or engaged in any activity resulting, or which may result, in the 
discharge or runoff of pollutants shall comply with all Federal, State, 
interstate and local requirements, administrative authority, and process 
and sanctions respecting the control and abatement of water pollution in 
the same manner and extent as any non-governmental entity in accordance 
with section 313 of the CWA.



Sec. 130.15  Processing application for Indian tribes.

    The Regional Administrator shall process an application of an Indian 
Tribe submitted under Sec. 130.6(d) in a timely manner. He shall 
promptly notify the Indian Tribe of receipt of the application.

[54 FR 14360, Apr. 11, 1989, as amended at 59 FR 13818, Mar. 23, 1994]



Sec. 130.16  Treatment of Indian tribes in a similar manner as states
for purposes of the Clean Water Act.

    (a) The Regional Administrator may accept and approve a tribal 
application for purposes of administering the Clean Water Act (CWA) 
Section 303(d) Impaired Water Listing and Total Maximum Daily Load

    (4) Where, after the effective date of this rule, EPA has determined 
that a tribe qualifies for TAS for the CWA Section 303(c) Water Quality 
Standards Program, CWA Section 402 National Pollutant Discharge 
Elimination System Program, or CWA Section 404 Dredge and Fill Permit 
Program, and provided notice and an opportunity to comment on the 
tribe's assertion of authority to appropriate governmental entities as 
part of its review of the

[[Page 519]]

tribe's prior application, no further notice to governmental entities, 
as described in paragraph (c)(2) of this section, shall be provided with 
regard to the same tribe's application for the CWA Section 303(d) 
Impaired Water Listing and TMDL Program, unless the application presents 
to the EPA Regional Administrator different jurisdictional issues or 
significant new factual or legal information relevant to jurisdiction.
    (5) Where the Regional Administrator determines that a tribe meets 
the requirements of this section, he or she shall promptly provide 
written notification to the tribe that the tribe is authorized to 
administer the CWA Section 303(d) Impaired Water Listing and TMDL 
Program. Such tribe shall be considered a ``State'' for purposes of CWA 
section 303(d) and its implementing regulations. With respect to the 
timing requirement for submittal of an authorized tribe's first list of 
impaired waters pursuant to Sec. 130.7(d)(1), the tribe's first list is 
due on the next listing cycle due date that is at least 24 months from 
the later of either:
    (i) The date EPA approves the tribe's TAS application pursuant to 
this section; or
    (ii) The date EPA-approved or EPA-promulgated water quality 
standards become effective for the tribe's reservation waters.

                      Subpart A_General Provisions



Sec. 131.1  Scope.

    This part describes the requirements and procedures for developing, 
reviewing, revising, and approving water quality standards by the States 
as authorized by section 303(c) of the Clean Water Act. Additional 
specific procedures for developing, reviewing, revising, and approving 
water quality standards for Great Lakes States or Great

[[Page 520]]

Lakes Tribes (as defined in 40 CFR 132.2) to conform to section 118 of 
the Clean Water Act and 40 CFR part 132, are provided in 40 CFR part 
132.

[60 FR 15386, Mar. 23, 1995]



Sec. 131.2  Purpose.

    A water quality standard defines the water quality goals of a water 
body, or portion thereof, by designating the use or uses to be made of 
the water and by setting criteria that protect the designated uses. 
States adopt water quality standards to protect public health or 
welfare, enhance the quality of water and serve the purposes of the 
Clean Water Act (the Act). ``Serve the purposes of the Act'' (as defined 
in sections 101(a)(2) and 303(c) of the Act) means that water quality 
standards should, wherever attainable, provide water quality for the 
protection and propagation of fish, shellfish and wildlife and for 
recreation in and on the water and take into consideration their use and 
value of public water supplies, propagation of fish, shellfish, and 
wildlife, recreation in and on the water, and agricultural, industrial, 
and other purposes including navigation.

Such standards serve the dual purposes of establishing the water quality 
goals for a specific water body and serve as the regulatory basis for 
the establishment of water-quality-based treatment controls and 
strategies beyond the technology-based levels of treatment required by 
sections 301(b) and 306 of the Act.

[48 FR 51405, Nov. 8, 1983, as amended at 80 FR 51046, Aug. 21, 2015]



Sec. 131.3  Definitions.

    (a) The Act means the Clean Water Act (Pub. L. 92-500, as amended 
(33 U.S.C. 1251 et seq.)).
    (b) Criteria are elements of State water quality standards, 
expressed as constituent concentrations, levels, or narrative 
statements, representing a quality of water that supports a particular 
use. When criteria are met, water quality will generally protect the 
designated use.
    (c) Section 304(a) criteria are developed by EPA under authority of 
section 304(a) of the Act based on the latest scientific information on 
the relationship that the effect of a constituent concentration has on 
particular aquatic species and/or human health. This information is 
issued periodically to the States as guidance for use in developing 
criteria.
    (d) Toxic pollutants are those pollutants listed by the 
Administrator under section 307(a) of the Act.
    (e) Existing uses are those uses actually attained in the water body 
on or after November 28, 1975, whether or not they are included in the 
water quality standards.
    (f) Designated uses are those uses specified in water quality 
standards for each water body or segment whether or not they are being 
attained.
    (g) Use attainability analysis is a structured scientific assessment 
of the factors affecting the attainment of the use which may include 
physical, chemical, biological, and economic factors as described in 
Sec. 131.10(g).
    (h) Water quality limited segment means any segment where it is 
known that water quality does not meet applicable water quality 
standards, and/or is not expected to meet applicable water quality 
standards, even after the application of the technology-based effluent 
limitations required by sections 301(b) and 306 of the Act.
    (i) Water quality standards are provisions of State or Federal law 
which consist of a designated use or uses for the waters of the United 
States and water quality criteria for such waters based upon such uses. 
Water quality standards are to protect the public health or welfare, 
enhance the quality of water and serve the purposes of the Act.
    (j) States include: The 50 States, the District of Columbia, Guam, 
the Commonwealth of Puerto Rico, Virgin Islands, American Samoa, the 
Commonwealth of the Northern Mariana Islands, and Indian Tribes that EPA 
determines to be eligible for purposes of the water quality standards 
program.
    (k) Federal Indian Reservation, Indian Reservation, or Reservation 
means all land within the limits of any Indian reservation under the 
jurisdiction of the United States Government, notwithstanding the 
issuance of any patent, and including rights-of-way running through the 
reservation.''

[[Page 521]]

    (l) Indian Tribe or Tribe means any Indian Tribe, band, group, or 
community recognized by the Secretary of the Interior and exercising 
governmental authority over a Federal Indian reservation.
    (m) Highest attainable use is the modified aquatic life, wildlife, 
or recreation use that is both closest to the uses specified in section 
101(a)(2) of the Act and attainable, based on the evaluation of the 
factor(s) in Sec. 131.10(g) that preclude(s) attainment of the use and 
any other information or analyses that were used to evaluate 
attainability. There is no required highest attainable use where the 
State demonstrates the relevant use specified in section 101(a)(2) of 
the Act and sub-categories of such a use are not attainable.
    (n) Practicable, in the context of Sec. 131.12(a)(2)(ii), means 
technologically possible, able to be put into practice, and economically 
viable.
    (o) A water quality standards variance (WQS variance) is a time-
limited designated use and criterion for a specific pollutant(s) or 
water quality parameter(s) that reflect the highest attainable condition 
during the term of the WQS variance.
    (p) Pollutant Minimization Program, in the context of Sec. 131.14, 
is a structured set of activities to improve processes and pollutant 
controls that will prevent and reduce pollutant loadings.
    (q) Non-101(a)(2) use is any use unrelated to the protection and 
propagation of fish, shellfish, wildlife or recreation in or on the 
water.

[48 FR 51405, Nov. 8, 1983, as amended at 56 FR 64893, Dec. 12, 1991; 59 
FR 64344, Dec. 14, 1994; 80 FR 51046, Aug. 21, 2015]



Sec. 131.4  State authority.

    (a) States (as defined in Sec. 131.3) are responsible for 
reviewing, establishing, and revising water quality standards. As 
recognized by section 510 of the Clean Water Act, States may develop 
water quality standards more stringent than required by this regulation. 
Consistent with section 101(g) and 518(a) of the Clean Water Act, water 
quality standards shall not be construed to supersede or abrogate rights 
to quantities of water.
    (b) States (as defined in Sec. 131.3) may issue certifications 
pursuant to the requirements of Clean Water Act section 401. Revisions 
adopted by States shall be applicable for use in issuing State 
certifications consistent with the provisions of Sec. 131.21(c).
    (c) Where EPA determines that a Tribe is eligible to the same extent 
as a State for purposes of water quality standards, the Tribe likewise 
is eligible to the same extent as a State for purposes of certifications 
conducted under Clean Water Act section 401.

[56 FR 64893, Dec. 12, 1991, as amended at 59 FR 64344, Dec. 14, 1994]



Sec. 131.5  EPA authority.

    (a) Under section 303(c) of the Act, EPA is to review and to approve 
or disapprove State-adopted water quality standards. The review involves 
a determination of:
    (1) Whether the State has adopted designated water uses that are 
consistent with the requirements of the Clean Water Act;
    (2) Whether the State has adopted criteria that protect the 
designated water uses based on sound scientific rationale consistent 
with Sec. 131.11;
    (3) Whether the State has adopted an antidegradation policy that is 
consistent with Sec. 131.12, and whether any State adopted 
antidegradation implementation methods are consistent with Sec. 131.12;
    (4) Whether any State adopted WQS variance is consistent with Sec. 
131.14;
    (5) Whether any State adopted provision authorizing the use of 
schedules of compliance for water quality-based effluent limits in NPDES 
permits is consistent with Sec. 131.15;
    (6) Whether the State has followed applicable legal procedures for 
revising or adopting standards;
    (7) Whether the State standards which do not include the uses 
specified in section 101(a)(2) of the Act are based upon appropriate 
technical and scientific data and analyses, and
    (8) Whether the State submission meets the requirements included in 
Sec. 131.6 of this part and, for Great Lakes States or Great Lakes 
Tribes (as defined in 40 CFR 132.2) to conform to section 118 of the 
Act, the requirements of 40 CFR part 132.

[[Page 522]]

    (b) If EPA determines that the State's or Tribe's water quality 
standards are consistent with the factors listed in paragraphs (a)(1) 
through (8) of this section, EPA approves the standards. EPA must 
disapprove the State's or Tribe's water quality standards and promulgate 
Federal standards under section 303(c)(4), and for Great Lakes States or 
Great Lakes Tribes under section 118(c)(2)(C) of the Act, if State or 
Tribal adopted standards are not consistent with the factors listed in 
paragraphs (a)(1) through (8) of this section. EPA may also promulgate a 
new or revised standard when necessary to meet the requirements of the 
Act.
    (c) Section 401 of the Clean Water Act authorizes EPA to issue 
certifications pursuant to the requirements of section 401 in any case 
where a State or interstate agency has no authority for issuing such 
certifications.

[48 FR 51405, Nov. 8, 1983, as amended at 56 FR 64894, Dec. 12, 1991; 60 
FR 15387, Mar. 23, 1995; 80 FR 51047, Aug. 21, 2015]



Sec. 131.6  Minimum requirements for water quality standards 
submission.

    The following elements must be included in each State's water 
quality standards submitted to EPA for review:
    (a) Use designations consistent with the provisions of sections 
101(a)(2) and 303(c)(2) of the Act.
    (b) Methods used and analyses conducted to support water quality 
standards revisions.
    (c) Water quality criteria sufficient to protect the designated 
uses.
    (d) An antidegradation policy consistent with Sec. 131.12.
    (e) Certification by the State Attorney General or other appropriate 
legal authority within the State that the water quality standards were 
duly adopted pursuant to State law.
    (f) General information which will aid the Agency in determining the 
adequacy of the scientific basis of the standards which do not include 
the uses specified in section 101(a)(2) of the Act as well as 
information on general policies applicable to State standards which may 
affect their application and implementation.



Sec. 131.7  Dispute resolution mechanism.

    (a) Where disputes between States and Indian Tribes arise as a 
result of differing water quality standards on common bodies of water, 
the lead EPA Regional Administrator, as determined based upon OMB 
circular A-105, shall be responsible for acting in accordance with the 
provisions of this section.
    (b) The Regional Administrator shall attempt to resolve such 
disputes where:
    (1) The difference in water quality standards results in 
unreasonable consequences;
    (2) The dispute is between a State (as defined in Sec. 131.3(j) but 
exclusive of all Indian Tribes) and a Tribe which EPA has determined is 
eligible to the same extent as a State for purposes of water quality 
standards;
    (3) A reasonable effort to resolve the dispute without EPA 
involvement has been made;
    (4) The requested relief is consistent with the provisions of the 
Clean Water Act and other relevant law;
    (5) The differing State and Tribal water quality standards have been 
adopted pursuant to State and Tribal law and approved by EPA; and
    (6) A valid written request has been submitted by either the Tribe 
or the State.
    (c) Either a State or a Tribe may request EPA to resolve any dispute 
which satisfies the criteria of paragraph (b) of this section. Written 
requests for EPA involvement should be submitted to the lead Regional 
Administrator and must include:
    (1) A concise statement of the unreasonable consequences that are 
alleged to have arisen because of differing water quality standards;
    (2) A concise description of the actions which have been taken to 
resolve the dispute without EPA involvement;
    (3) A concise indication of the water quality standards provision 
which has resulted in the alleged unreasonable consequences;
    (4) Factual data to support the alleged unreasonable consequences; 
and
    (5) A statement of the relief sought from the alleged unreasonable 
consequences.
    (d) Where, in the Regional Administrator's judgment, EPA involvement 
is

[[Page 523]]

appropriate based on the factors of paragraph (b) of this section, the 
Regional Administrator shall, within 30 days, notify the parties in 
writing that he/she is initiating an EPA dispute resolution action and 
solicit their written response. The Regional Administrator shall also 
make reasonable efforts to ensure that other interested individuals or 
groups have notice of this action. Such efforts shall include but not be 
limited to the following:
    (1) Written notice to responsible Tribal and State Agencies, and 
other affected Federal agencies,
    (2) Notice to the specific individual or entity that is alleging 
that an unreasonable consequence is resulting from differing standards 
having been adopted on a common body of water,
    (3) Public notice in local newspapers, radio, and television, as 
appropriate,
    (4) Publication in trade journal newsletters, and
    (5) Other means as appropriate.
    (e) If in accordance with applicable State and Tribal law an Indian 
Tribe and State have entered into an agreement that resolves the dispute 
or establishes a mechanism for resolving a dispute, EPA shall defer to 
this agreement where it is consistent with the Clean Water Act and where 
it has been approved by EPA.
    (f) EPA dispute resolution actions shall be consistent with one or a 
combination of the following options:
    (1) Mediation. The Regional Administrator may appoint a mediator to 
mediate the dispute. Mediators shall be EPA employees, employees from 
other Federal agencies, or other individuals with appropriate 
qualifications.
    (i) Where the State and Tribe agree to participate in the dispute 
resolution process, mediation with the intent to establish Tribal-State 
agreements, consistent with Clean Water Act section 518(d), shall 
normally be pursued as a first effort.
    (ii) Mediators shall act as neutral facilitators whose function is 
to encourage communication and negotiation between all parties to the 
dispute.
    (iii) Mediators may establish advisory panels, to consist in part of 
representatives from the affected parties, to study the problem and 
recommend an appropriate solution.
    (iv) The procedure and schedule for mediation of individual disputes 
shall be determined by the mediator in consultation with the parties.
    (v) If formal public hearings are held in connection with the 
actions taken under this paragraph, Agency requirements at 40 CFR 25.5 
shall be followed.
    (2) Arbitration. Where the parties to the dispute agree to 
participate in the dispute resolution process, the Regional 
Administrator may appoint an arbitrator or arbitration panel to 
arbitrate the dispute. Arbitrators and panel members shall be EPA 
employees, employees from other Federal agencies, or other individuals 
with appropriate qualifications. The Regional administrator shall select 
as arbitrators and arbitration panel members individuals who are 
agreeable to all parties, are knowledgeable concerning the requirements 
of the water quality standards program, have a basic understanding of 
the political and economic interests of Tribes and States involved, and 
are expected to fulfill the duties fairly and impartially.
    (i) The arbitrator or arbitration panel shall conduct one or more 
private or public meetings with the parties and actively solicit 
information pertaining to the effects of differing water quality permit 
requirements on upstream and downstream dischargers, comparative risks 
to public health and the environment, economic impacts, present and 
historical water uses, the quality of the waters subject to such 
standards, and other factors relevant to the dispute, such as whether 
proposed water quality criteria are more stringent than necessary to 
support designated uses, more stringent than natural background water 
quality or whether designated uses are reasonable given natural 
background water quality.
    (ii) Following consideration of relevant factors as defined in 
paragraph (f)(2)(i) of this section, the arbitrator or arbitration panel 
shall have the authority and responsibility to provide all parties and 
the Regional Administrator with a written recommendation for resolution 
of the dispute. Arbitration panel recommendations shall, in general, be 
reached by majority vote. However, where the parties agree to

[[Page 524]]

binding arbitration, or where required by the Regional Administrator, 
recommendations of such arbitration panels may be unanimous decisions. 
Where binding or non-binding arbitration panels cannot reach a unanimous 
recommendation after a reasonable period of time, the Regional 
Administrator may direct the panel to issue a non-binding decision by 
majority vote.
    (iii) The arbitrator or arbitration panel members may consult with 
EPA's Office of General Counsel on legal issues, but otherwise shall 
have no ex parte communications pertaining to the dispute. Federal 
employees who are arbitrators or arbitration panel members shall be 
neutral and shall not be predisposed for or against the position of any 
disputing party based on any Federal Trust responsibilities which their 
employers may have with respect to the Tribe. In addition, arbitrators 
or arbitration panel members who are Federal employees shall act 
independently from the normal hierarchy within their agency.
    (iv) The parties are not obligated to abide by the arbitrator's or 
arbitration panel's recommendation unless they voluntarily entered into 
a binding agreement to do so.
    (v) If a party to the dispute believes that the arbitrator or 
arbitration panel has recommended an action contrary to or inconsistent 
with the Clean Water Act, the party may appeal the arbitrator's 
recommendation to the Regional Administrator. The request for appeal 
must be in writing and must include a description of the statutory basis 
for altering the arbitrator's recommendation.
    (vi) The procedure and schedule for arbitration of individual 
disputes shall be determined by the arbitrator or arbitration panel in 
consultation with parties.
    (vii) If formal public hearings are held in connection with the 
actions taken under this paragraph, Agency requirements at 40 CFR 25.5 
shall be followed.
    (3) Dispute resolution default procedure. Where one or more parties 
(as defined in paragraph (g) of this section) refuse to participate in 
either the mediation or arbitration dispute resolution processes, the 
Regional Administrator may appoint a single official or panel to review 
available information pertaining to the dispute and to issue a written 
recommendation for resolving the dispute. Review officials shall be EPA 
employees, employees from other Federal agencies, or other individuals 
with appropriate qualifications. Review panels shall include appropriate 
members to be selected by the Regional Administrator in consultation 
with the participating parties. Recommendations of such review officials

           Subpart B_Establishment of Water Quality Standards



Sec. 131.10  Designation of uses.

    (a) Each State must specify appropriate water uses to be achieved 
and protected. The classification of the waters of the State must take 
into consideration the use and value of water for public water supplies, 
protection and propagation of fish, shellfish and wildlife, recreation 
in and on the water, agricultural, industrial, and other purposes 
including navigation. If adopting new or revised designated uses other 
than the uses specified in section 101(a)(2) of the Act, or removing 
designated uses, States must submit documentation justifying how their 
consideration of the use and value of water for those uses listed in 
this paragraph appropriately supports the State's action. A use 
attainability analysis may be used to satisfy this requirement. In no 
case shall a State adopt waste transport or waste assimilation as a 
designated use for any waters of the United States.
    (b) In designating uses of a water body and the appropriate criteria 
for those uses, the State shall take into consideration the water 
quality standards of downstream waters and shall ensure that its water 
quality standards provide for the attainment and maintenance of the 
water quality standards of downstream waters.
    (c) States may adopt sub-categories of a use and set the appropriate 
criteria to reflect varying needs of such sub-categories of uses, for 
instance, to differentiate between cold water and warm water fisheries.
    (d) At a minimum, uses are deemed attainable if they can be achieved 
by the imposition of effluent limits required under sections 301(b) and 
306 of the Act and cost-effective and reasonable best management 
practices for nonpoint source control.
    (e) [Reserved]
    (f) States may adopt seasonal uses as an alternative to 
reclassifying a water body or segment thereof to uses requiring less 
stringent water quality criteria. If seasonal uses are adopted, water 
quality criteria should be adjusted to reflect the seasonal uses, 
however, such criteria shall not preclude the attainment and maintenance 
of a more protective use in another season.
    (g) States may designate a use, or remove a use that is not an 
existing use, if the State conducts a use attainability analysis as 
specified in paragraph (j) of this section that demonstrates attaining 
the use is not feasible because of one of the six factors in this 
paragraph. If a State adopts a new or revised water quality standard 
based on a required use attainability analysis, the State shall also 
adopt the highest attainable use, as defined in Sec. 131.3(m).

[[Page 527]]

    (1) Naturally occurring pollutant concentrations prevent the 
attainment of the use; or
    (2) Natural, ephemeral, intermittent or low flow conditions or water 
levels prevent the attainment of the use, unless these conditions may be 
compensated for by the discharge of sufficient volume of effluent 
discharges without violating State water conservation requirements to 
enable uses to be met; or
    (3) Human caused conditions or sources of pollution prevent the 
attainment of the use and cannot be remedied or would cause more 
environmental damage to correct than to leave in place; or
    (4) Dams, diversions or other types of hydrologic modifications 
preclude the attainment of the use, and it is not feasible to restore 
the water body to its original condition or to operate such modification 
in a way that would result in the attainment of the use; or
    (5) Physical conditions related to the natural features of the water 
body, such as the lack of a proper substrate, cover, flow, depth, pools, 
riffles, and the like, unrelated to water quality, preclude attainment 
of aquatic life protection uses; or
    (6) Controls more stringent than those required by sections 301(b) 
and 306 of the Act would result in substantial and widespread economic 
and social impact.
    (h) States may not remove designated uses if:
    (1) They are existing uses, as defined in Sec. 131.3, unless a use 
requiring more stringent criteria is added; or
    (2) Such uses will be attained by implementing effluent limits 
required under sections 301(b) and 306 of the Act and by implementing 
cost-effective and reasonable best management practices for nonpoint 
source control.
    (i) Where existing water quality standards specify designated uses 
less than those which are presently being attained, the State shall 
revise its standards to reflect the uses actually being attained.
    (j) A State must conduct a use attainability analysis as described 
in Sec. 131.3(g), and paragraph (g) of this section, whenever:
    (1) The State designates for the first time, or has previously 
designated for a water body, uses that do not include the uses specified 
in section 101(a)(2) of the Act; or
    (2) The State wishes to remove a designated use that is specified in 
section 101(a)(2) of the Act, to remove a sub-category of such a use, or 
to designate a sub-category of such a use that requires criteria less 
stringent than previously applicable.
    (k) A State is not required to conduct a use attainability analysis 
whenever:
    (1) The State designates for the first time, or has previously 
designated for a water body, uses that include the uses specified in 
section 101(a)(2) of the Act; or
    (2) The State designates a sub-category of a use specified in 
section 101(a)(2) of the Act that requires criteria at least as 
stringent as previously applicable; or
    (3) The State wishes to remove or revise a designated use that is a 
non-101(a)(2) use. In this instance, as required by paragraph (a) of 
this section, the State must submit documentation justifying how its 
consideration of the use and value of water for those uses listed in 
paragraph (a) appropriately supports the State's action, which may be 
satisfied through a use attainability analysis.

[48 FR 51405, Nov. 8, 1983, as amended at 80 FR 51047, Aug. 21, 2015]



Sec. 131.11  Criteria.

    (a) Inclusion of pollutants: (1) States must adopt those water 
quality criteria that protect the designated use. Such criteria must be 
based on sound scientific rationale and must contain sufficient 
parameters or constituents to protect the designated use. For waters 
with multiple use designations, the criteria shall support the most 
sensitive use.
    (2) Toxic pollutants. States must review water quality data and 
information on discharges to identify specific water bodies where toxic 
pollutants may be adversely affecting water quality or the attainment of 
the designated water use or where the levels of toxic pollutants are at 
a level to warrant concern and must adopt criteria for such toxic 
pollutants applicable to the

[[Page 528]]

water body sufficient to protect the designated use. Where a State 
adopts narrative criteria for toxic pollutants to protect designated 
uses, the State must provide information identifying the method by which 
the State intends to regulate point source discharges of toxic 
pollutants on water quality limited segments based on such narrative 
criteria. Such information may be included as part of the standards or 
may be included in documents generated by the State in response to the 
Water Quality Planning and Management Regulations (40 CFR part 130).
    (b) Form of criteria: In establishing criteria, States should:
    (1) Establish numerical values based on:
    (i) 304(a) Guidance; or
    (ii) 304(a) Guidance modified to reflect site-specific conditions; 
or
    (iii) Other scientifically defensible methods;
    (2) Establish narrative criteria or criteria based upon 
biomonitoring methods where numerical criteria cannot be established or 
to supplement numerical criteria.

[48 FR 51405, Nov. 8, 1983, as amended at 51047, Aug. 21, 2015]



Sec. 131.12  Antidegradation policy and implementation methods.

    (a) The State shall develop and adopt a statewide antidegradation 
policy. The antidegradation policy shall, at a minimum, be consistent 
with the following:
    (1) Existing instream water uses and the level of water quality 
necessary to protect the existing uses shall be maintained and 
protected.
    (2) Where the quality of the waters exceeds levels necessary to 
support the protection and propagation of fish, shellfish, and wildlife 
and recreation in and on the water, that quality shall be maintained and 
protected unless the State finds, after full satisfaction of the 
intergovernmental coordination and public participation provisions of 
the State's continuing planning process, that allowing lower water 
quality is necessary to accommodate important economic or social 
development in the area in which the waters are located. In allowing 
such degradation or lower water quality, the State shall assure water 
quality adequate to protect existing uses fully. Further, the State 
shall assure that there shall be achieved the highest statutory and 
regulatory requirements for all new and existing point sources and all 
cost-effective and reasonable best management practices for nonpoint 
source control.
    (i) The State may identify waters for the protections described in 
paragraph (a)(2) of this section on a parameter-by-parameter basis or on 
a water body-by-water body basis. Where the State identifies waters for 
antidegradation protection on a water body-by-water body basis, the 
State shall provide an opportunity for public involvement in any 
decisions about whether the protections described in paragraph (a)(2) of 
this section will be afforded to a water body, and the factors 
considered when making those decisions. Further, the State shall not 
exclude a water body from the protections described in paragraph (a)(2) 
of this section solely because water quality does not exceed levels 
necessary to support all of the uses specified in section 101(a)(2) of 
the Act.
    (ii) Before allowing any lowering of high water quality, pursuant to 
paragraph (a)(2) of this section, the State shall find, after an 
analysis of alternatives, that such a lowering is necessary to 
accommodate important economic or social development in the area in 
which the waters are located. The analysis of alternatives shall 
evaluate a range of practicable alternatives that would prevent or 
lessen the degradation associated with the proposed activity. When the 
analysis of alternatives identifies one or more practicable 
alternatives, the State shall only find that a lowering is necessary if 
one such alternative is selected for implementation.
    (3) Where high quality waters constitute an outstanding National 
resource, such as waters of National and State parks and wildlife 
refuges and waters of exceptional recreational or ecological 
significance, that water quality shall be maintained and protected.
    (4) In those cases where potential water quality impairment 
associated with a thermal discharge is involved,

[[Page 529]]

the antidegradation policy and implementing method shall be consistent 
with section 316 of the Act.
    (b) The State shall develop methods for implementing the 
antidegradation policy that are, at a minimum, consistent with the 
State's policy and with paragraph (a) of this section. The State shall 
provide an opportunity for public involvement during the development and 
any subsequent revisions of the implementation methods, and shall make 
the methods available to the public.

[48 FR 51405, Nov. 8, 1983, as amended at 80 FR 51047, Aug. 21, 2015]



Sec. 131.13  General policies.

    States may, at their discretion, include in their State standards, 
policies generally affecting their application and implementation, such 
as mixing zones, low flows and variances. Such policies are subject to 
EPA review and approval.



Sec. 131.14  Water quality standards variances.

    States may adopt WQS variances, as defined in Sec. 131.3(o). Such a 
WQS variance is subject to the provisions of this section and public 
participation requirements at Sec. 131.20(b). A WQS variance is a water 
quality standard subject to EPA review and approval or disapproval.
    (a) Applicability. (1) A WQS variance may be adopted for a 
permittee(s) or water body/waterbody segment(s), but only applies to the 
permittee(s) or water body/waterbody segment(s) specified in the WQS 
variance.
    (2) Where a State adopts a WQS variance, the State must retain, in 
its standards, the underlying designated use and criterion addressed by 
the WQS variance, unless the State adopts and EPA approves a revision to 
the underlying designated use and criterion consistent with Sec. Sec. 
131.10 and 131.11. All other applicable standards not specifically 
addressed by the WQS variance remain applicable.
    (3) A WQS variance, once adopted by the State and approved by EPA, 
shall be the applicable standard for purposes of the Act under Sec. 
131.21(d) through (e), for the following limited purposes. An approved 
WQS variance applies for the purposes of developing NPDES permit limits 
and requirements under 301(b)(1)(C), where appropriate, consistent with 
paragraph (a)(1) of this section. States and other certifying entities 
may also use an approved WQS variance when issuing certifications under 
section 401 of the Act.
    (4) A State may not adopt WQS variances if the designated use and 
criterion addressed by the WQS variance can be achieved by implementing 
technology-based effluent limits required under sections 301(b) and 306 
of the Act.
    (b) Requirements for Submission to EPA. (1) A WQS variance must 
include:
    (i) Identification of the pollutant(s) or water quality 
parameter(s), and the water body/waterbody segment(s) to which the WQS 
variance applies. Discharger(s)-specific WQS variances must also 
identify the permittee(s) subject to the WQS variance.
    (ii) The requirements that apply throughout the term of the WQS 
variance. The requirements shall represent the highest attainable 
condition of the water body or waterbody segment applicable throughout 
the term of the WQS variance based on the documentation required in 
(b)(2) of this section. The requirements shall not result in any 
lowering of the currently attained ambient water quality, unless a WQS 
variance is necessary for restoration activities, consistent with 
paragraph (b)(2)(i)(A)(2) of this section. The State must specify the 
highest attainable condition of the water body or waterbody segment as a 
quantifiable expression that is one of the following:
    (A) For discharger(s)-specific WQS variances:
    (1) The highest attainable interim criterion; or
    (2) The interim effluent condition that reflects the greatest 
pollutant reduction achievable; or
    (3) If no additional feasible pollutant control technology can be 
identified, the interim criterion or interim effluent condition that 
reflects the greatest pollutant reduction achievable with the pollutant 
control technologies installed at the time the State adopts the WQS 
variance, and the adoption and implementation of a Pollutant 
Minimization Program.

[[Page 530]]

    (B) For WQS variances applicable to a water body or waterbody 
segment:
    (1) The highest attainable interim use and interim criterion; or
    (2) If no additional feasible pollutant control technology can be 
identified, the interim use and interim criterion that reflect the 
greatest pollutant reduction achievable with the pollutant control 
technologies installed at the time the State adopts the WQS variance, 
and the adoption and implementation of a Pollutant Minimization Program.
    (iii) A statement providing that the requirements of the WQS 
variance are either the highest attainable condition identified at the 
time of the adoption of the WQS variance, or the highest attainable 
condition later identified during any reevaluation consistent with 
paragraph (b)(1)(v) of this section, whichever is more stringent.
    (iv) The term of the WQS variance, expressed as an interval of time 
from the date of EPA approval or a specific date. The term of the WQS 
variance must only be as long as necessary to achieve the highest 
attainable condition and consistent with the demonstration provided in 
paragraph (b)(2) of this section. The State may adopt a subsequent WQS 
variance consistent with this section.
    (v) For a WQS variance with a term greater than five years, a 
specified frequency to reevaluate the highest attainable condition using 
all existing and readily available information and a provision 
specifying how the State intends to obtain public input on the 
reevaluation. Such reevaluations must occur no less frequently than 
every five years after EPA approval of the WQS variance and the results 
of such reevaluation must be submitted to EPA within 30 days of 
completion of the reevaluation.
    (vi) A provision that the WQS variance will no longer be the 
applicable water quality standard for purposes of the Act if the State 
does not conduct a reevaluation consistent with the frequency specified 
in the WQS variance or the results are not submitted to EPA as required 
by (b)(1)(v) of this section.
    (2) The supporting documentation must include:
    (i) Documentation demonstrating the need for a WQS variance.
    (A) For a WQS variance to a use specified in section 101(a)(2) of 
the Act or a sub-category of such a use, the State must demonstrate that 
attaining the designated use and criterion is not feasible throughout 
the term of the WQS variance because:
    (1) One of the factors listed in Sec. 131.10(g) is met, or
    (2) Actions necessary to facilitate lake, wetland, or stream 
restoration through dam removal or other significant reconfiguration 
activities preclude attainment of the designated use and criterion while 
the actions are being implemented.
    (B) For a WQS variance to a non-101(a)(2) use, the State must submit 
documentation justifying how its consideration of the use and value of 
the water for those uses listed in Sec. 131.10(a) appropriately 
supports the WQS variance and term. A demonstration consistent with 
paragraph (b)(2)(i)(A) of this section may be used to satisfy this 
requirement.
    (ii) Documentation demonstrating that the term of the WQS variance 
is only as long as necessary to achieve the highest attainable 
condition. Such documentation must justify the term of the WQS variance 
by describing the pollutant control activities to achieve the highest 
attainable condition, including those activities identified through a 
Pollutant Minimization Program, which serve as milestones for the WQS 
variance.
    (iii) In addition to paragraphs (b)(2)(i) and (ii) of this section, 
for a WQS variance that applies to a water body or waterbody segment:
    (A) Identification and documentation of any cost-effective and 
reasonable best management practices for nonpoint source controls 
related to the pollutant(s) or water quality parameter(s) and water body 
or waterbody segment(s) specified in the WQS variance that could be 
implemented to make progress towards attaining the underlying designated 
use and criterion. A State must provide public notice and comment for 
any such documentation.
    (B) Any subsequent WQS variance for a water body or waterbody 
segment

[[Page 531]]

must include documentation of whether and to what extent best management 
practices for nonpoint source controls were implemented to address the 
pollutant(s) or water quality parameter(s) subject to the WQS variance 
and the water quality progress achieved.
    (c) Implementing WQS variances in NPDES permits. A WQS variance 
serves as the applicable water quality standard for implementing NPDES 
permitting requirements pursuant to Sec. 122.44(d) of this chapter for 
the term of the WQS variance. Any limitations and requirements necessary 
to implement the WQS variance shall be included as enforceable 
conditions of the NPDES permit for the permittee(s) subject to the WQS 
variance.

[80 FR 51048, Aug. 21, 2015]



Sec. 131.15  Authorizing the use of schedules of compliance for water
quality-based effluent limits in NPDES permits.

    If a State intends to authorize the use of schedules of compliance 
for water quality-based effluent limits in NPDES permits, the State must 
adopt a permit compliance schedule authorizing provision. Such 
authorizing provision is a water quality standard subject to EPA review 
and approval under section 303 of the Act and must be consistent with 
sections 502(17) and 301(b)(1)(C) of the Act.

[80 FR 51049, Aug. 21, 2015]



 Subpart C_Procedures for Review and Revision of Water Quality Standards



Sec. 131.20  State review and revision of water quality standards.

    (a) State review. The State shall from time to time, but at least 
once every 3 years, hold public hearings for the purpose of reviewing 
applicable water quality standards adopted pursuant to Sec. Sec. 131.10 
through 131.15 and Federally promulgated water quality standards and, as 
appropriate, modifying and adopting standards. The State shall also re-
examine any waterbody segment with water quality standards that do not 
include the uses specified in section 101(a)(2) of the Act every 3 years 
to determine if any new information has become available. If such new 
information indicates that the uses specified in section 101(a)(2) of 
the Act are attainable, the State shall revise its standards 
accordingly. Procedures States establish for identifying and reviewing 
water bodies for review should be incorporated into their Continuing 
Planning Process. In addition, if a State does not adopt new or revised 
criteria for parameters for which EPA has published new or updated CWA 
section 304(a) criteria recommendations, then the State shall provide an 
explanation when it submits the results of its triennial review to the 
Regional Administrator consistent with CWA section 303(c)(1) and the 
requirements of paragraph (c) of this section.
    (b) Public participation. The State shall hold one or more public 
hearings for the purpose of reviewing water quality standards as well as 
when revising water quality standards, in accordance with provisions of 
State law and EPA's public participation regulation (40 CFR part 25). 
The proposed water quality standards revision and supporting analyses 
shall be made available to the public prior to the hearing.
    (c) Submittal to EPA. The State shall submit the results of the 
review, any supporting analysis for the use attainability analysis, the 
methodologies used for site-specific criteria development, any general 
policies applicable to water quality standards and any revisions of the 
standards to the Regional Administrator for review and approval, within 
30 days of the final State action to adopt and certify the revised 
standard, or if no revisions are made as a result of the review, within 
30 days of the completion of the review.

[48 FR 51405, Nov. 8, 1983, as amended at 80 FR 51049, Aug. 21, 2015]



Sec. 131.21  EPA review and approval of water quality standards.

    (a) After the State submits its officially adopted revisions, the 
Regional Administrator shall either:
    (1) Notify the State within 60 days that the revisions are approved, 
or
    (2) Notify the State within 90 days that the revisions are 
disapproved. Such notification of disapproval shall

[[Page 532]]

specify the changes needed to assure compliance with the requirements of 
the Act and this regulation, and shall explain why the State standard is 
not in compliance with such requirements. Any new or revised State 
standard must be accompanied by some type of supporting analysis.
    (b) The Regional Administrator's approval or disapproval of a State 
water quality standard shall be based on the requirements of the Act as 
described in Sec. Sec. 131.5 and 131.6, and, with respect to Great 
Lakes States or Tribes (as defined in 40 CFR 132.2), 40 CFR part 132.
    (c) How do I determine which water quality standards are applicable 
for purposes of the Act? You may determine which water quality standards 
are applicable water quality standards for purposes of the Act from the

    (d) When do I use the applicable water quality standards identified 
in paragraph (c) above? Applicable water quality standards for purposes 
of the Act are the minimum standards which must be used when the CWA and 
regulations implementing the CWA refer to water quality standards, for 
example, in identifying impaired waters and calculating TMDLs under 
section 303(d), developing NPDES permit limitations under section 
301(b)(1)(C), evaluating proposed discharges of dredged or fill material 
under section 404, and in issuing certifications under section 401 of 
the Act.
    (e) For how long does an applicable water quality standard for 
purposes of the Act remain the applicable water quality standard for 
purposes of the Act? A State or authorized Tribe's applicable water 
quality standard for purposes of the Act remains the applicable standard 
until EPA approves a change, deletion, or addition to that water quality 
standard, or until EPA promulgates a more stringent water quality 
standard.
    (f) How can I find out what the applicable standards are for 
purposes of the Act? In each Regional office, EPA maintains a docket 
system for the States and authorized Tribes in that Region, available to 
the public, identifying the applicable water quality standards for 
purposes of the Act.

    (3) Procedures for site specific modification of listed waterbodies 
or temperature criteria for bull trout.
    (i) The Regional Administrator may, in his discretion, determine 
that the temperature criteria in paragraph (a)(1) of this section shall 
not apply to a specific waterbody or portion thereof listed in paragraph 
(a)(2) of this section. Any such determination shall be made consistent 
with Sec. 131.11 and shall be based on a finding that bull trout 
spawning and rearing is not an existing use in such waterbody or portion 
thereof.
    (ii) The Regional Administrator may, in his discretion, raise the 
temperature criteria in paragraph (a)(1) of this section as they pertain 
to a specific waterbody or portion thereof listed in paragraph (a)(2) of 
this section. Any such determination shall be made consistent with Sec. 
131.11, and shall be based on a finding that bull trout would be fully 
supported at the higher temperature criteria.
    (iii) For any determination made under paragraphs (a)(3)(i) or 
(a)(3)(ii) of this section, the Regional Administrator shall, prior to 
making such a determination, provide for public notice of and comment on 
a proposed determination. For any such proposed determination, the 
Regional Administrator shall prepare and make available to the public a 
technical support document addressing each waterbody or portion thereof 
that would be deleted or modified and the justification for each 
proposed determination. This document shall be made available to the 
public not later than the date of public notice.
    (iv) The Regional Administrator shall maintain and make available to 
the public an updated list of determinations made pursuant to paragraphs 
(a)(3)(i) and (a)(3)(ii) of this section as well as the technical 
support documents for each determination.
    (v) Nothing in this paragraph (a)(3) shall limit the Administrator's 
authority to modify the temperature criteria in paragraph (a)(1) of this 
section or the list of waterbodies in paragraph (a)(2) of this section 
through rulemaking.
    (b) [Reserved]
    (c) Excluded waters. Lakes, ponds, pools, streams, and springs 
outside public lands but located wholly and entirely upon a person's 
land are not protected specifically or generally for any beneficial use, 
unless such waters are designated in Idaho 16.01.02.110. through 160., 
or, although not so designated, are waters of the United States as 
defined at 40 CFR 122.2.

    (c) Water quality standard variances. The Regional Administrator, 
EPA Region 7, is authorized to grant variances from the water quality 
standards in paragraphs (a) and (b) of this section where the 
requirements of Sec. 131.14 are met.

[68 FR 40442, July 7, 2003, as amended at 80 FR 51050, Aug. 21, 2015]



Sec. 131.35  Colville Confederated Tribes Indian Reservation.

    The water quality standards applicable to the waters within the 
Colville Indian Reservation, located in the State of Washington.
    (a) Background. (1) It is the purpose of these Federal water quality 
standards to prescribe minimum water quality requirements for the 
surface waters located within the exterior boundaries of the Colville 
Indian Reservation to ensure compliance with section 303(c) of the Clean 
Water Act.
    (2) The Colville Confederated Tribes have a primary interest in the 
protection, control, conservation, and utilization of the water 
resources of the Colville Indian Reservation. Water quality standards 
have been enacted into tribal law by the Colville Business Council of 
the Confederated Tribes of the Colville Reservation, as the Colville 
Water Quality Standards Act, CTC Title 33 (Resolution No. 1984-526 
(August 6, 1984) as amended by Resolution No. 1985-20 (January 18, 
1985)).
    (b) Territory covered. The provisions of these water quality 
standards shall apply to all surface waters within the exterior 
boundaries of the Colville Indian Reservation.
    (c) Applicability, Administration and Amendment. (1) The water 
quality standards in this section shall be used by the Regional 
Administrator for establishing any water quality based National 
Pollutant Discharge Elimination System Permit (NPDES) for point sources 
on the Colville Confederated Tribes Reservation.
    (2) In conjunction with the issuance of section 402 or section 404 
permits, the Regional Administrator may designate mixing zones in the 
waters of the United States on the reservation on a case-by-case basis. 
The size of such mixing zones and the in-zone water quality in such 
mixing zones shall be consistent with the applicable procedures and 
guidelines in EPA's Water Quality Standards Handbook and the Technical 
Support Document for Water Quality Based Toxics Control.
    (3) Amendments to the section at the request of the Tribe shall 
proceed in the following manner.
    (i) The requested amendment shall first be duly approved by the 
Confederated Tribes of the Colville Reservation (and so certified by the 
Tribes Legal Counsel) and submitted to the Regional Administrator.
    (ii) The requested amendment shall be reviewed by EPA (and by the 
State of Washington, if the action would affect a boundary water).
    (iii) If deemed in compliance with the Clean Water Act, EPA will 
propose and promulgate an appropriate change to this section.
    (4) Amendment of this section at EPA's initiative will follow 
consultation with the Tribe and other appropriate entities. Such 
amendments will then follow normal EPA rulemaking procedures.
    (5) All other applicable provisions of this part 131 shall apply on 
the Colville Confederated Tribes Reservation. Special attention should 
be paid to Sec. Sec. 131.6, 131.10, 131.11 and 131.20 for any amendment 
to these standards to be initiated by the Tribe.
    (6) All numeric criteria contained in this section apply at all in-
stream flow rates greater than or equal to the flow rate calculated as 
the minimum 7-consecutive day average flow with a recurrence frequency 
of once in ten years (7Q10); narrative criteria (Sec. 131.35(e)(3)) 
apply regardless of flow. The 7Q10 low flow shall be calculated using 
methods recommended by the U.S. Geological Survey.
    (d) Definitions. (1) Acute toxicity means a deleterious response 
(e.g.,

[[Page 565]]

mortality, disorientation, immobilization) to a stimulus observed in 96 
hours or less.
    (2) Background conditions means the biological, chemical, and 
physical conditions of a water body, upstream from the point or non-
point source discharge under consideration. Background sampling location 
in an enforcement action will be upstream from the point of discharge, 
but not upstream from other inflows. If several discharges to any water 
body exist, and an enforcement action is being taken for possible 
violations to the standards, background sampling will be undertaken 
immediately upstream from each discharge.
    (3) Ceremonial and Religious water use means activities involving 
traditional Native American spiritual practices which involve, among 
other things, primary (direct) contact with water.
    (4) Chronic toxicity means the lowest concentration of a constituent 
causing observable effects (i.e., considering lethality, growth, reduced 
reproduction, etc.) over a relatively long period of time, usually a 28-
day test period for small fish test species.
    (5) Council or Tribal Council means the Colville Business Council of 
the Colville Confederated Tribes.
    (6) Geometric mean means the nth root of a product of n factors.
    (7) Mean retention time means the time obtained by dividing a 
reservoir's mean annual minimum total storage by the non-zero 30-day, 
ten-year low-flow from the reservoir.
    (8) Mixing zone or dilution zone means a limited area or volume of 
water where initial dilution of a discharge takes place; and where 
numeric water quality criteria can be exceeded but acutely toxic 
conditions are prevented from occurring.
    (9) pH means the negative logarithm of the hydrogen ion 
concentration.
    (10) Primary contact recreation means activities where a person 
would have direct contact with water to the point of complete 
submergence, including but not limited to skin diving, swimming, and 
water skiing.
    (11) Regional Administrator means the Administrator of EPA's Region 
X.
    (12) Reservation means all land within the limits of the Colville 
Indian Reservation, established on July 2, 1872 by Executive Order, 
presently containing 1,389,000 acres more or less, and under the 
jurisdiction of the United States government, notwithstanding the 
issuance of any patent, and including rights-of-way running through the 
reservation.
    (13) Secondary contact recreation means activities where a person's 
water contact would be limited to the extent that bacterial infections 
of eyes, ears, respiratory, or digestive systems or urogenital areas 
would normally be avoided (such as wading or fishing).
    (14) Surface water means all water above the surface of the ground 
within the exterior boundaries of the Colville Indian Reservation 
including but not limited to lakes, ponds, reservoirs, artificial 
impoundments, streams, rivers, springs, seeps and wetlands.
    (15) Temperature means water temperature expressed in Centigrade 
degrees (C).
    (16) Total dissolved solids (TDS) means the total filterable residue 
that passes through a standard glass fiber filter disk and remains after 
evaporation and drying to a constant weight at 180 degrees C. it is 
considered to be a measure of the dissolved salt content of the water.
    (17) Toxicity means acute and/or chronic toxicity.
    (18) Tribe or Tribes means the Colville Confederated Tribes.
    (19) Turbidity means the clarity of water expressed as nephelometric 
turbidity units (NTU) and measured with a calibrated turbidimeter.
    (20) Wildlife habitat means the waters and surrounding land areas of 
the Reservation used by fish, other aquatic life and wildlife at any 
stage of their life history or activity.
    (e) General considerations. The following general guidelines shall 
apply to the water quality standards and classifications set forth in 
the use designation Sections.
    (1) Classification boundaries. At the boundary between waters of 
different classifications, the water quality standards for the higher 
classification shall prevail.
    (2) Antidegradation policy. This antidegradation policy shall be 
applicable to all surface waters of the Reservation.

[[Page 566]]

    (i) Existing in-stream water uses and the level of water quality 
necessary to protect the existing uses shall be maintained and 
protected.
    (ii) Where the quality of the waters exceeds levels necessary to 
support propagation of fish, shellfish, and wildlife and recreation in 
and on the water, that quality shall be maintained and protected unless 
the Regional Administrator finds, after full satisfaction of the inter-
governmental coordination and public participation provisions of the 
Tribes' continuing planning process, that allowing lower water quality 
is necessary to accommodate important economic or social development in 
the area in which the waters are located. In allowing such degradation 
or lower water quality, the Regional Administrator shall assure water 
quality adequate to protect existing uses fully. Further, the Regional 
Administrator shall assure that there shall be achieved the highest 
statutory and regulatory requirements for all new and existing point 
sources and all cost-effective and reasonable best management practices 
for nonpoint source control.
    (iii) Where high quality waters are identified as constituting an 
outstanding national or reservation resource, such as waters within 
areas designated as unique water quality management areas and waters 
otherwise of exceptional recreational or ecological significance, and 
are designated as special resource waters, that water quality shall be 
maintained and protected.
    (iv) In those cases where potential water quality impairment 
associated with a thermal discharge is involved, this antidegradation 
policy's implementing method shall be consistent with section 316 of the 
Clean Water Act.
    (3) Aesthetic qualities. All waters within the Reservation, 
including those within mixing zones, shall be free from substances, 
attributable to wastewater discharges or other pollutant sources, that:
    (i) Settle to form objectionable deposits;
    (ii) Float as debris, scum, oil, or other matter forming nuisances;
    (iii) Produce objectionable color, odor, taste, or turbidity;
    (iv) Cause injury to, are toxic to, or produce adverse physiological 
responses in humans, animals, or plants; or
    (v) produce undesirable or nuisance aquatic life.
    (4) Analytical methods. (i) The analytical testing methods used to 
measure or otherwise evaluate compliance with water quality standards 
shall to the extent practicable, be in accordance with the ``Guidelines 
Establishing Test Procedures for the Analysis of Pollutants'' (40 CFR 
part 136). When a testing method is not available for a particular 
substance, the most recent edition of ``Standard Methods for the 
Examination of Water and Wastewater'' (published by the American Public 
Health Association, American Water Works Association, and the Water 
Pollution Control Federation) and other or superseding methods published 
and/or approved by EPA shall be used.
    (f) General water use and criteria classes. The following criteria 
shall apply to the various classes of surface waters on the Colville 
Indian Reservation:
    (1) Class I (Extraordinary)--(i) Designated uses. The designated 
uses include, but are not limited to, the following:
    (A) Water supply (domestic, industrial, agricultural).

the background turbidity is 50 NTU or less, or have more than a 20 
percent increase in turbidity when the background turbidity is more than 
50 NTU.
    (F) Toxic, radioactive, nonconventional, or deleterious material 
concentrations shall be less than those of public health significance, 
or which may cause acute or chronic toxic conditions to the aquatic 
biota, or which may adversely affect designated water uses.
    (5) Lake Class--(i) Designated uses. The designated uses include but 
are not limited to, the following:
    (A) Water supply (domestic, industrial, agricultural).
    (B) Stock watering.

    (ii) Water quality criteria. (A) Bacteriological Criteria. The 
geometric mean of the enterococci bacteria densities in samples taken 
over a 30 day period shall not exceed 33/100 ml, nor shall any single 
sample exceed an enterococci density of 150 per 100 milliliters. These 
limits are calculated as the geometric mean of the collected samples 
approximately equally spaced over a thirty day period.
    (B) Dissolved oxygen--no measurable decrease from natural 
conditions.
    (C) Total dissolved gas concentrations shall not exceed 110 percent 
of the saturation value for gases at the existing atmospheric and 
hydrostatic pressures at any point of sample collection.
    (D) Temperature--no measurable change from natural conditions.
    (E) pH--no measurable change from natural conditions.
    (F) Turbidity shall not exceed 5 NTU over natural conditions.
    (G) Toxic, radioactive, nonconventional, or deleterious material 
concentrations shall be less than those which may affect public health, 
the natural aquatic environment, or the desirability of the water for 
any use.
    (6) Special Resource Water Class (SRW)--(i) General characteristics. 
These are fresh or saline waters which comprise a special and unique 
resource to the Reservation. Water quality of this class will be varied 
and unique as determined by the Regional Administrator in cooperation 
with the Tribes.
    (ii) Designated uses. The designated uses include, but are not 
limited to, the following:
    (A) Wildlife habitat.
    (B) Natural foodchain maintenance.
    (iii) Water quality criteria.

conditions.
    (B) Dissolved oxygen--shall not show any measurable decrease from 
natural conditions.
    (C) Total dissolved gas shall not vary from natural conditions.
    (D) Temperature--shall not show any measurable change from natural 
conditions.
    (E) pH shall not show any measurable change from natural conditions.
    (F) Settleable solids shall not show any change from natural 
conditions.
    (G) Turbidity shall not exceed 5 NTU over natural conditions.
    (H) Toxic, radioactive, or deleterious material concentrations shall 
not exceed those found under natural conditions.

    (g) General classifications. General classifications applying to 
various surface waterbodies not specifically classified under Sec. 
131.35(h) are as follows:
    (1) All surface waters that are tributaries to Class I waters are 
classified Class I, unless otherwise classified.
    (2) Except for those specifically classified otherwise, all lakes 
with existing average concentrations less than 2000 mg/L TDS and their 
feeder streams on the Colville Indian Reservation are classified as Lake 
Class and Class I, respectively.
    (3) All lakes on the Colville Indian Reservation with existing 
average concentrations of TDS equal to or exceeding 2000 mg/L and their 
feeder streams are classified as Lake Class and Class I respectively 
unless specifically classified otherwise.
    (4) All reservoirs with a mean detention time of greater than 15 
days are classified Lake Class.
    (5) All reservoirs with a mean detention time of 15 days or less are 
classified the same as the river section in which they are located.
    (6) All reservoirs established on pre-existing lakes are classified 
as Lake Class.
    (7) All wetlands are assigned to the Special Resource Water Class.

    a. Criteria revised to reflect current agency q1* or RfD, 
as contained in the Integrated Risk Information System (IRIS). The fish 
tissue bioconcentration factor (BCF) from the 1980 criteria documents 
was retained in all cases.
    b. The criteria refers to the inorganic form only.
    c. Criteria in the matrix based on carcinogenicity (10-6 
risk). For a risk level of 10-5, move the decimal point in 
the matrix value one place to the right.
    d. Criteria Maximum Concentration (CMC) = the highest concentration 
of a pollutant to which aquatic life can be exposed for a short period 
of time (1-hour average) without deleterious effects. Criteria 
Continuous Concentration (CCC) = the highest concentration of a 
pollutant to which aquatic life can be exposed for an extended period of 
time (4 days) without deleterious effects. [micro] g/L = micrograms per 
liter.
    e. Freshwater aquatic life criteria for these metals are expressed 
as a function of total hardness (mg/L as CaCO3), the 
pollutant's water effect ratio (WER) as defined in Sec. 131.36(c) and 
multiplied by an appropriate dissolved conversion factor as defined in 
Sec. 131.36(b)(2). For comparative purposes, the values displayed in 
this matrix are shown as dissolved metal and correspond to a total 
hardness of 100 mg/L and a water effect ratio of 1.0.
    f. Freshwater aquatic life criteria for pentachlorophenol are 
expressed as a function of pH, and are calculated as follows. Values 
displayed above in the matrix correspond to a pH of 7.8.

 CMC = exp(1.005(pH)-4.830)
 CCC = exp(1.005(pH)-5.290)

    g. Aquatic life criteria for these compounds were issued in 1980 
utilizing the 1980 Guidelines for criteria development. The acute values 
shown are final acute values (FAV) which by the 1980 Guidelines are 
instantaneous values as contrasted with a CMC which is a one-hour 
average.
    h. These totals simply sum the criteria in each column. For aquatic 
life, there are 31 priority toxic pollutants with some type of 
freshwater or saltwater, acute or chronic criteria. For human health, 
there are 85 priority toxic pollutants with either ``water + fish'' or 
``fish only'' criteria. Note that these totals count chromium as one 
pollutant even though EPA has developed criteria based on two valence 
states. In the matrix, EPA has assigned numbers 5a and 5b to the 
criteria for chromium to reflect the fact that the list of 126 priority 
toxic pollutants includes only a single listing for chromium.
    i. If the CCC for total mercury exceeds 0.012 [micro] g/l more than 
once in a 3-year period in the ambient water, the edible portion of 
aquatic species of concern must be analyzed to determine whether the 
concentration of methyl mercury exceeds the FDA action level (1.0 mg/
kg). If the FDA action level is exceeded, the State must notify the 
appropriate EPA Regional Administrator, initiate a revision of its 
mercury criterion in its water quality standards so as to protect 
designated uses, and take other appropriate action such as issuance of a 
fish consumption advisory for the affected area.
    j. No criteria for protection of human health from consumption of 
aquatic organisms (excluding water) was presented in the

[[Page 575]]

1980 criteria document or in the 1986 Quality Criteria for Water. 
Nevertheless, sufficient information was presented in the 1980 document 
to allow a calculation of a criterion, even though the results of such a 
calculation were not shown in the document.
    k. The criterion for asbestos is the MCL (56 FR 3526, January 30, 
1991).
    l. [Reserved: This letter not used as a footnote.]
    m. Criteria for these metals are expressed as a function of the 
water effect ratio, WER, as defined in 40 CFR 131.36(c).

CMC = column B1 or C1 value x WER
CCC = column B2 or C2 value x WER

    n. EPA is not promulgating human health criteria for this 
contaminant. However, permit authorities should address this contaminant 
in NPDES permit actions using the State's existing narrative criteria 
for toxics.
    o. [Reserved: This letter not used as a footnote.]
    p. Criterion expressed as total recoverable.
    q. This criterion applies to total PCBs (e.g., the sum of all 
congener or isomer or homolog or Aroclor analyses).

                              General Notes

    1. This chart lists all of EPA's priority toxic pollutants whether 
or not criteria recommendations are available. Blank spaces indicate the 
absence of criteria recommendations. Because of variations in chemical 
nomenclature systems, this listing of toxic pollutants does not 
duplicate the listing in Appendix A of 40 CFR Part 423. EPA has added 
the Chemical Abstracts Service (CAS) registry numbers, which provide a 
unique identification for each chemical.
    2. The following chemicals have organoleptic based criteria 
recommendations that are not included on this chart (for reasons which 
are discussed in the preamble): copper, zinc, chlorobenzene, 2-
chlorophenol, 2,4-dichlorophenol, acenaphthene, 2,4-dimethylphenol, 3-
methyl-4-chlorophenol, hexachlorocyclopentadiene, pentachlorophenol, 
phenol.
    3. For purposes of this rulemaking, freshwater criteria and 
saltwater criteria apply as specified in 40 CFR 131.36(c).

    Note to paragraph (b)(1):
    On April 14, 1995, the Environmental Protection Agency issued a stay 
of certain criteria in paragraph (b)(1) of this section as follows: the 
criteria in columns B and C for arsenic, cadmium, chromium (VI), copper, 
lead, nickel, silver, and zinc; the criteria in B1 and C1 for mercury; 
the criteria in column B for chromium (III); and the criteria in column 
C for selenium. The stay remains in effect until further notice.

    (2) Factors for Calculating Hardness-Dependent, Freshwater Metals 
Criteria

CMC = WER exp { mA[ln(hardness)] + bA{time}  x 
          Acute Conversion Factor
CCC = WER exp { mC[ln(hardness)] + bC{time}  x 
          Chronic Conversion Factor
Final CMC and CCC values should be rounded to two significant figures.

Footnotes to table:
\a\ The freshwater conversion factors (CF) for cadmium and lead are hardness-dependent and can be calculated for
  any hardness [see limitations in Sec. 131.36(c)(4)] using the following equations:
 
 Cadmium
Acute: CF = 1.136672--[(ln hardness)(0.041838)]
Chronic: CF = 1.101672--[(ln hardness)(0.041838)]
Lead (Acute and Chronic): CF = 1.46203--[(ln hardness)(0.145712)]
 
 \b\ No chronic criteria are available for silver.

    (c) Applicability. (1) The criteria in paragraph (b) of this section 
apply to the States' designated uses cited in paragraph (d) of this 
section and supersede any criteria adopted by the State, except when 
State regulations contain criteria which are more stringent for a 
particular use in which case the State's criteria will continue to 
apply.
    (2) The criteria established in this section are subject to the 
State's general rules of applicability in the same way and to the same 
extent as are the other numeric toxics criteria when applied to the same 
use classifications including mixing zones, and low flow values below 
which numeric standards can be exceeded in flowing fresh waters.

[[Page 576]]

    (i) For all waters with mixing zone regulations or implementation 
procedures, the criteria apply at the appropriate locations within or at 
the boundary of the mixing zones; otherwise the criteria apply 
throughout the waterbody including at the end of any discharge pipe, 
canal or other discharge point.
    (ii) A State shall not use a low flow value below which numeric 
standards can be exceeded that is less stringent than the following for 
waters suitable for the establishment of low flow return frequencies 
(i.e., streams and rivers):

                              Aquatic Life
Acute criteria (CMC)                 1 Q 10 or 1 B 3
Chronic criteria (CCC)               7 Q 10 or 4 B 3
                              Human Health
Non-carcinogens                      30 Q 5
Carcinogens                          Harmonic mean flow
 

Where:

CMC--criteria maximum concentration--the water quality criteria to 
          protect against acute effects in aquatic life and is the 
          highest instream concentration of a priority toxic pollutant 
          consisting of a one-hour average not to be exceeded more than 
          once every three years on the average;
CCC--criteria continuous concentration--the water quality criteria to 
          protect against chronic effects in aquatic life is the highest 
          instream concentration of a priority toxic pollutant 
          consisting of a 4-day average not to be exceeded more than 
          once every three years on the average;
1 Q 10 is the lowest one day flow with an average recurrence frequency 
          of once in 10 years determined hydrologically;
1 B 3 is biologically based and indicates an allowable exceedence of 
          once every 3 years. It is determined by EPA's computerized 
          method (DFLOW model);
7 Q 10 is the lowest average 7 consecutive day low flow with an average 
          recurrence frequency of once in 10 years determined 
          hydrologically;
4 B 3 is biologically based and indicates an allowable exceedence for 4 
          consecutive days once every 3 years. It is determined by EPA's 
          computerized method (DFLOW model);
30 Q 5 is the lowest average 30 consecutive day low flow with an average 
          recurrence frequency of once in 5 years determined 
          hydrologically; and the harmonic mean flow is a long term mean 
          flow value calculated by dividing the number of daily flows 
          analyzed by the sum of the reciprocals of those daily flows.

    (iii) If a State does not have such a low flow value for numeric 
standards compliance, then none shall apply and the criteria included in 
paragraph (d) of this section herein apply at all flows.
    (3) The aquatic life criteria in the matrix in paragraph (b) of this 
section apply as follows:
    (i) For waters in which the salinity is equal to or less than 1 part 
per thousand 95% or more of the time, the applicable criteria are the 
freshwater criteria in Column B;
    (ii) For waters in which the salinity is equal to or greater than 10 
parts per thousand 95% or more of the time, the applicable criteria are 
the saltwater criteria in Column C; and
    (iii) For waters in which the salinity is between 1 and 10 parts per 
thousand as defined in paragraphs (c)(3) (i) and (ii) of this section, 
the applicable criteria are the more stringent of the freshwater or 
saltwater criteria. However, the Regional Administrator may approve the 
use of the alternative freshwater or saltwater criteria if 
scientifically defensible information and data demonstrate that on a 
site-specific basis the biology of the waterbody is dominated by 
freshwater aquatic life and that freshwater criteria are more 
appropriate; or conversely, the biology of the waterbody is dominated by 
saltwater aquatic life and that saltwater criteria are more appropriate.
    (4) Application of metals criteria. (i) For purposes of calculating 
freshwater aquatic life criteria for metals from the equations in 
paragraph (b)(2) of this section, the minimum hardness allowed for use 
in those equations shall not be less than 25 mg/l, as calcium carbonate, 
even if the actual ambient hardness is less than 25 mg/l as calcium 
carbonate. The maximum hardness value for use in those equations shall 
not exceed 400 mg/l as calcium carbonate, even if the actual ambient 
hardness is greater than 400 mg/l as calcium carbonate. The same 
provisions apply for calculating the metals criteria for the comparisons 
provided for in paragraph (c)(3)(iii) of this section.
    (ii) The hardness values used shall be consistent with the design 
discharge conditions established in paragraph (c)(2) of this section for 
flows and mixing zones.
    (iii) Except where otherwise noted, the criteria for metals 
(compounds 2,

[[Page 577]]

4- 11, and 13, in paragraph (b) of this section) are expressed as 
dissolved metal. For purposes of calculating aquatic life criteria for 
metals from the equations in footnote m. in the criteria matrix in 
paragraph (b)(1) of this section and the equations in paragraphs (b)(2) 
of this section, the water-effect ratio is computed as a specific 
pollutant's acute or chronic toxicity values measured in water from the 
site covered by the standard, divided by the respective acute or chronic 
toxicity value in laboratory dilution water.

    (10) California, EPA Region 9. (i) All waters assigned any aquatic 
life or human health use classifications in the Water Quality Control 
Plans for the various Basins of the State (``Basin Plans''), as amended, 
adopted by the California State Water Resources Control Board 
(``SWRCB''), except for ocean waters covered by the Water Quality 
Control Plan for Ocean Waters of California (``Ocean Plan'') adopted by 
the SWRCB with resolution Number 90-27 on March 22, 1990, are subject to 
the criteria in paragraph (d)(10)(ii) of this section, without 
exception. These criteria amend the portions of the existing State 
standards contained in the Basin Plans. More particularly these criteria 
amend water quality criteria contained in the Basin Plan Chapters 
specifying water quality objectives (the State equivalent of federal 
water quality criteria) for the toxic pollutants identified in paragraph 
(d)(10)(ii) of this section. Although the State has adopted several use 
designations for each of these waters, for purposes of this action, the 
specific standards to be applied in paragraph (d)(10)(ii) of this 
section are based on the presence in all waters of some aquatic life 
designation and the presence or absence of the MUN use designation 
(Municipal and domestic supply). (See Basin Plans for more detailed use 
definitions.)

    (a) Additional criteria. The following criteria are applicable to 
waters specified in the Water Quality Control Plan for Salinity for the 
San Francisco Bay/Sacramento-San Joaquin Delta Estuary, adopted by the 
California State Water Resources Control Board in State Board Resolution 
No. 91-34 on May 1, 1991:
    (1) Estuarine habitat criteria. (i) General rule. (A) Salinity 
(measured at the surface) shall not exceed 2640 micromhos/centimeter 
specific conductance at 25 [deg]C (measured as a 14-day moving average) 
at the Confluence of the Sacramento and San Joaquin Rivers throughout 
the period each year from February 1 through June 30, and shall not 
exceed 2640 micromhos/centimeter specific conductance at 25 [deg]C 
(measured as a 14-day moving average) at the specific locations noted in 
Table 1 near Roe Island and Chipps Island for the number of days each 
month in the February 1 to June 30 period computed by reference to the 
following formula:

Number of days required in Month X = Total number of days in Month x * 
(1 - 1/(1 + e\K\)

where

K = A + (B*natural logarithm of the previous month's 8-River Index);
A and B are determined by reference to Table 1 for the Roe Island and 
          Chipps Island locations;
x is the calendar month in the February 1 to June 30 period;

[[Page 582]]

and e is the base of the natural (or Napierian) logarithm.


Where the number of days computed in this equation in paragraph 
(a)(1)(i)(A) of this section shall be rounded to the nearest whole 
number of days. When the previous month's 8-River Index is less than 
500,000 acre-feet, the number of days required for the current month 
shall be zero.

\1\ Coefficients for A and B are not provided at Chipps Island for February, because the 2640 micromhos/cm
  specific conductance criteria must be maintained at Chipps Island throughout February under all historical 8-
  River Index values for January.

    (B) The Roe Island criteria apply at the salinity measuring station 
maintained by the U.S. Bureau of Reclamation at Port Chicago (km 64). 
The Chipps Island criteria apply at the Mallard Slough Monitoring Site, 
Station D-10 (RKI RSAC-075) maintained by the California Department of 
Water Resources. The Confluence criteria apply at the Collinsville 
Continuous Monitoring Station C-2 (RKI RSAC-081) maintained by the 
California Department of Water Resources.
    (ii) Exception. The criteria at Roe Island shall be required for any 
given month only if the 14-day moving average salinity at Roe Island 
falls below 2640 micromhos/centimeter specific conductance on any of the 
last 14 days of the previous month.
    (2) Fish migration criteria--(i) General rule--(A) Sacramento River. 
Measured Fish Migration criteria values for the Sacramento River shall 
be at least the following:

At temperatures less than below 61 [deg]F: SRFMC = 1.35
At temperatures between 61 [deg]F and 72 [deg]F: SRFMC = 6.96-.092 * 
Fahrenheit temperature
At temperatures greater than 72 [deg]F: SRFMC = 0.34


where SRFMC is the Sacramento River Fish Migration criteria value. 
Temperature shall be the water temperature at release of tagged salmon 
smolts into the Sacramento River at Miller Park.
    (B) San Joaquin River. Measured Fish Migration criteria values on 
the San Joaquin River shall be at least the following:

For years in which the SJVIndex is 2.5: SJFMC = (-0.012) + 
0.184*SJVIndex
In other years: SJFMC = 0.205 + 0.0975*SJVIndex


where SJFMC is the San Joaquin River Fish Migration criteria value, and 
SJVIndex is the San Joaquin Valley Index in million acre feet (MAF)
    (ii) Computing fish migration criteria values for Sacramento River. 
In order to assess fish migration criteria values for the Sacramento 
River, tagged fall-run salmon smolts will be released into the 
Sacramento River at Miller Park and captured at Chipps Island, or 
alternatively released at Miller Park and Port Chicago and recovered 
from the ocean fishery, using the methodology described in this 
paragraph (a)(2)(ii). An alternative methodology for computing fish 
migration criteria values can be used so long as the revised methodology 
is calibrated with the methodology described in this paragraph 
(a)(2)(ii) so as to maintain the validity of the relative index values. 
Sufficient releases shall be made each year to provide a statistically 
reliable verification of compliance with the criteria. These criteria 
will be considered attained when the sum of the differences between the 
measured experimental value and the stated criteria

[[Page 583]]

value (i.e., measured value minus stated value) for each experimental 
release conducted over a three year period (the current year and the 
previous two years) shall be greater than or equal to zero. Fish for 
release are to be tagged at the hatchery with coded-wire tags, and fin 
clipped. Approximately 50,000 to 100,000 fish of smolt size (size 
greater than 75 mm) are released for each survival index estimate, 
depending on expected mortality. As a control for the ocean recovery 
survival index, one or two groups per season are released at Benecia or 
Pt. Chicago. From each upstream release of tagged fish, fish are to be 
caught over a period of one to two weeks at Chipps Island. Daylight 
sampling at Chipps Island with a 9.1 by 7.9 m, 3.2 mm cod end, midwater 
trawl is begun 2 to 3 days after release. When the first fish is caught, 
full-time trawling 7 days a week should begin. Each day's trawling 
consists of ten 20 minute tows generally made against the current, and 
distributed equally across the channel.
    (A) The Chipps Island smolt survival index is calculated as:

SSI = R / MT(0.007692)

where

R = number of recaptures of tagged fish
M = number of marked (tagged) fish released
T = proportion of time sampled vs total time tagged fish were passing 
          the site (i.e. time between first and last tagged fish 
          recovery)


Where the value 0.007692 is the proportion of the channel width fished 
by the trawl, and is calculated as trawl width/channel width.
    (B) Recoveries of tagged fish from the ocean salmon fishery two to 
four years after release are also used to calculate a survival index for 
each release. Smolt survival indices from ocean recoveries are 
calculated as:

OSI = R1/M1 / R2/M2

where

R1 = number of tagged adults recovered from the upstream 
          release
M1 = number released upstream
R2 = number of tagged adults recovered from the Port Chicago 
          release
M2 = number released at Port Chicago

    (1) The number of tagged adults recovered from the ocean fishery is 
provided by the Pacific States Marine Fisheries Commission, which 
maintains a port sampling program.
    (2) [Reserved]
    (iii) Computing fish migration criteria values for San Joaquin 
River. In order to assess annual fish migration criteria values for the 
San Joaquin River, tagged salmon smolts will be released into the San 
Joaquin River at Mossdale and captured at Chipps Island, or 
alternatively released at Mossdale and Port Chicago and recovered from 
the ocean fishery, using the methodology described in paragraph 
(a)(2)(iii). An alternative methodology for computing fish migration 
criteria values can be used so long as the revised methodology is 
calibrated with the methodology described below so as to maintain the 
validity of the relative index values. Sufficient releases shall be made 
each year to provide a statistically reliable estimate of the SJFMC for 
the year. These criteria will be considered attained when the sum of the 
differences between the measured experimental value and the stated 
criteria value (i.e., measured value minus stated value) for each 
experimental release conducted over a three year period (the current 
year and the previous two years) shall be greater than or equal to zero.
    (A) Fish for release are to be tagged at the hatchery with coded-
wire tags, and fin clipped. Approximately 50,000 to 100,000 fish of 
smolt size (size greater than 75 mm) are released for each survival 
index estimate, depending on expected mortality. As a control for the 
ocean recovery survival index, one or two groups per season are released 
at Benicia or Pt. Chicago. From each upstream release of tagged fish, 
fish are to be caught over a period of one to two weeks at Chipps 
Island. Daylight sampling at Chipps Island with a 9.1 by 7.9 m, 3.2 mm 
cod end, midwater trawl is begun 2 to 3 days after release. When the 
first fish is caught, full-time trawling 7 days a week should begin. 
Each day's trawling consists of ten 20 minute tows generally made 
against the current, and distributed equally across the channel.
    (B) The Chipps Island smolt survival index is calculated as:

SSI = R / MT(0.007692)


[[Page 584]]


where

R = number of recaptures of tagged fish
M = number of marked (tagged) fish released
T = proportion of time sampled vs total time tagged fish were passing 
          the site (i.e. time between first and last tagged fish 
          recovery)

Where the value 0.007692 is the proportion of the channel width fished 
by the trawl, and is calculated as trawl width/channel width.
    (C) Recoveries of tagged fish from the ocean salmon fishery two to 
four years after release are also used to calculate a survival index for 
each release. Smolt survival indices from ocean recoveries are 
calculated as:

OSI = R1/M1 / R2/M2

where

R1 = number of tagged adults recovered from the upstream 
          release
M1 = number released upstream
R2 = number of tagged adults recovered from the Port Chicago 
          release
M2 = number released at Port Chicago

    (1) The number of tagged adults recovered from the ocean fishery is 
provided by the Pacific States Marine Fisheries Commission, which 
maintains a port sampling program.
    (2) [Reserved]
    (3) Suisun marsh criteria. (i) Water quality conditions sufficient 
to support a natural gradient in species composition and wildlife 
habitat characteristic of a brackish marsh throughout all elevations of 
the tidal marshes bordering Suisun Bay shall be maintained. Water 
quality conditions shall be maintained so that none of the following 
occurs: Loss of diversity; conversion of brackish marsh to salt marsh; 
for animals, decreased population abundance of those species vulnerable 
to increased mortality and loss of habitat from increased water 
salinity; or for plants, significant reduction in stature or percent 
cover from increased water or soil salinity or other water quality 
parameters.
    (ii) [Reserved]
    (b) Revised criteria. The following criteria are applicable to state 
waters specified in Table 1-1, at Section (C)(3) (``Striped Bass--
Salinity : 3. Prisoners Point--Spawning) of the Water Quality Control 
Plan for Salinity for the San Francisco Bay--Sacramento/San Joaquin 
Delta Estuary, adopted by the California State Water Resources Control 
Board in State Board Resolution No. 91-34 on May 1, 1991:

    (c) Definitions. Terms used in paragraphs (a) and (b) of this 
section, shall be defined as follows:
    (1) Water year. A water year is the twelve calendar months beginning 
October 1.
    (2) 8-River Index. The flow determinations are made and are 
published by the California Department of Water Resources in Bulletin 
120. The 8-River Index shall be computed as the sum of flows at the 
following stations:
    (i) Sacramento River at Band Bridge, near Red Bluff;
    (ii) Feather River, total inflow to Oroville Reservoir;
    (iii) Yuba River at Smartville;
    (iv) American River, total inflow to Folsom Reservoir;
    (v) Stanislaus River, total inflow to New Melones Reservoir;
    (vi) Tuolumne River, total inflow to Don Pedro Reservoir;
    (vii) Merced River, total inflow to Exchequer Reservoir; and
    (viii) San Joaquin River, total inflow to Millerton Lake.
    (3) San Joaquin Valley Index. (i) The San Joaquin Valley Index is 
computed according to the following formula:

ISJ = 0.6X + 0.2Y and 0.2Z

where

ISJ = San Joaquin Valley Index
X = Current year's April-July San Joaquin Valley unimpaired runoff
Y = Current year's October-March San Joaquin Valley unimpaired runoff
Z = Previous year's index in MAF, not to exceed 0.9 MAF

    (ii) Measuring San Joaquin Valley unimpaired runoff. San Joaquin 
Valley unimpaired runoff for the current water year is a forecast of the 
sum of the following locations: Stanislaus River, total flow to New 
Melones Reservoir; Tuolumne River, total inflow to Don Pedro Reservoir; 
Merced River, total flow to Exchequer Reservoir; San Joaquin River, 
total inflow to Millerton Lake.
    (4) Salinity. Salinity is the total concentration of dissolved ions 
in water. It shall be measured by specific conductance in accordance 
with the procedures set forth in 40 CFR 136.3, Table 1B, Parameter 64.

[60 FR 4707, Jan. 24, 1995]



Sec. 131.38  Establishment of numeric criteria for priority toxic
pollutants for the State of California.

    (a) Scope. This section promulgates criteria for priority toxic 
pollutants in the State of California for inland surface waters and 
enclosed bays and estuaries. This section also contains a compliance 
schedule provision.
    (b)(1) Criteria for Priority Toxic Pollutants in the State of 
California as described in the following table:

[[Page 586]]

[GRAPHIC] [TIFF OMITTED] TR18MY00.007


[[Page 587]]


[GRAPHIC] [TIFF OMITTED] TR18MY00.008


[[Page 588]]


[GRAPHIC] [TIFF OMITTED] TR18MY00.009


[[Page 589]]


[GRAPHIC] [TIFF OMITTED] TR18MY00.010

                 Footnotes to table in paragraph (b)(1):

    a. Criteria revised to reflect the Agency q1* or RfD, as contained 
in the Integrated Risk Information System (IRIS) as of October 1, 1996. 
The fish tissue bioconcentration factor (BCF) from the 1980 documents 
was retained in each case.
    b. Criteria apply to California waters except for those waters 
subject to objectives in Tables III-2A and III-2B of the San Francisco 
Regional Water Quality Control Board's (SFRWQCB) 1986 Basin Plan that 
were adopted by the SFRWQCB and the State Water Resources Control Board, 
approved by EPA, and which continue to apply. For copper and nickel, 
criteria apply to California waters except for waters south of Dumbarton 
Bridge in San Francisco Bay that are subject to the objectives in the 
SFRWQCB's Basin Plan as amended by SFRWQCB Resolution R2-2002-0061, 
dated May 22, 2002, and approved by the State Water Resources Control 
Board. EPA approved the aquatic life site-specific objectives on January 
21, 2003. The copper and nickel aquatic life site-specific objectives 
contained in the amended Basin Plan apply instead.
    c. Criteria are based on carcinogenicity of 10 (-6) risk.
    d. Criteria Maximum Concentration (CMC) equals the highest 
concentration of a pollutant to which aquatic life can be exposed for a 
short period of time without deleterious effects. Criteria Continuous 
Concentration (CCC) equals the highest concentration of a pollutant to 
which aquatic life can be exposed for an extended period of time (4 
days) without deleterious effects. ug/L equals micrograms per liter.
    e. Freshwater aquatic life criteria for metals are expressed as a 
function of total hardness (mg/L) in the water body. The equations are 
provided in matrix at paragraph (b)(2) of this section. Values displayed 
above in the matrix correspond to a total hardness of 100 mg/l.
    f. Freshwater aquatic life criteria for pentachlorophenol are 
expressed as a function of pH, and are calculated as follows:

[[Page 590]]

Values displayed above in the matrix correspond to a pH of 7.8. CMC = 
exp(1.005(pH)-4.869). CCC = exp(1.005(pH)-5.134).
    g. This criterion is based on 304(a) aquatic life criterion issued 
in 1980, and was issued in one of the following documents: Aldrin/
Dieldrin (EPA 440/5-80-019), Chlordane (EPA 440/5-80-027), DDT (EPA 440/
5-80-038), Endosulfan (EPA 440/5-80-046), Endrin (EPA 440/5-80-047), 
Heptachlor (440/5-80-052), Hexachlorocyclohexane (EPA 440/5-80-054), 
Silver (EPA 440/5-80-071). The Minimum Data Requirements and derivation 
procedures were different in the 1980 Guidelines than in the 1985 
Guidelines. For example, a ``CMC'' derived using the 1980 Guidelines was 
derived to be used as an instantaneous maximum. If assessment is to be 
done using an averaging period, the values given should be divided by 2 
to obtain a value that is more comparable to a CMC derived using the 
1985 Guidelines.
    h. These totals simply sum the criteria in each column. For aquatic 
life, there are 23 priority toxic pollutants with some type of 
freshwater or saltwater, acute or chronic criteria. For human health, 
there are 92 priority toxic pollutants with either ``water + organism'' 
or ``organism only'' criteria. Note that these totals count chromium as 
one pollutant even though EPA has developed criteria based on two 
valence states. In the matrix, EPA has assigned numbers 5a and 5b to the 
criteria for chromium to reflect the fact that the list of 126 priority 
pollutants includes only a single listing for chromium.
    i. Criteria for these metals are expressed as a function of the 
water-effect ratio, WER, as defined in paragraph (c) of this section. 
CMC = column B1 or C1 value x WER; CCC = column B2 or C2 value x WER.
    j. No criterion for protection of human health from consumption of 
aquatic organisms (excluding water) was presented in the 1980 criteria 
document or in the 1986 Quality Criteria for Water. Nevertheless, 
sufficient information was presented in the 1980 document to allow a 
calculation of a criterion, even though the results of such a 
calculation were not shown in the document.
    k. The CWA 304(a) criterion for asbestos is the MCL.
    l. [Reserved]
    m. These freshwater and saltwater criteria for metals are expressed 
in terms of the dissolved fraction of the metal in the water column. 
Criterion values were calculated by using EPA's Clean Water Act 304(a) 
guidance values (described in the total recoverable fraction) and then 
applying the conversion factors in Sec. 131.36(b)(1) and (2).
    n. EPA is not promulgating human health criteria for these 
contaminants. However, permit authorities should address these 
contaminants in NPDES permit actions using the State's existing 
narrative criteria for toxics.
    o. These criteria were promulgated for specific waters in California 
in the National Toxics Rule (``NTR''), at Sec. 131.36. The specific 
waters to which the NTR criteria apply include: Waters of the State 
defined as bays or estuaries and waters of the State defined as inland, 
i.e., all surface waters of the State not ocean waters. These waters 
specifically include the San Francisco Bay upstream to and including 
Suisun Bay and the Sacramento-San Joaquin Delta. This section does not 
apply instead of the NTR for this criterion.
    p. A criterion of 20 ug/l was promulgated for specific waters in 
California in the NTR and was promulgated in the total recoverable form. 
The specific waters to which the NTR criterion applies include: Waters 
of the San Francisco Bay upstream to and including Suisun Bay and the 
Sacramento-San Joaquin Delta; and waters of Salt Slough, Mud Slough 
(north) and the San Joaquin River, Sack Dam to the mouth of the Merced 
River. This section does not apply instead of the NTR for this 
criterion. The State of California adopted and EPA approved a site 
specific criterion for the San Joaquin River, mouth of Merced to 
Vernalis; therefore, this section does not apply to these waters.
    q. This criterion is expressed in the total recoverable form. This 
criterion was promulgated for specific waters in California in the NTR 
and was promulgated in the total recoverable form. The specific waters 
to which the NTR criterion applies include: Waters of the San Francisco 
Bay upstream to and including Suisun Bay and the Sacramento-San Joaquin 
Delta; and waters of Salt Slough, Mud Slough (north) and the San Joaquin 
River, Sack Dam to Vernalis. This criterion does not apply instead of 
the NTR for these waters. This criterion applies to additional waters of 
the United States in the State of California pursuant to 40 CFR 
131.38(c). The State of California adopted and EPA approved a site-
specific criterion for the Grassland Water District, San Luis National 
Wildlife Refuge, and the Los Banos State Wildlife Refuge; therefore, 
this criterion does not apply to these waters.
    r. These criteria were promulgated for specific waters in California 
in the NTR. The specific waters to which the NTR criteria apply include: 
Waters of the State defined as bays or estuaries including the 
Sacramento-San Joaquin Delta within California Regional Water Board 5, 
but excluding the San Francisco Bay. This section does not apply instead 
of the NTR for these criteria.
    s. These criteria were promulgated for specific waters in California 
in the NTR. The specific waters to which the NTR criteria apply include: 
Waters of the Sacramento-San Joaquin Delta and waters of the State 
defined as inland (i.e., all surface waters of the State not bays or 
estuaries or ocean) that include a MUN use designation. This section

[[Page 591]]

does not apply instead of the NTR for these criteria.
    t. These criteria were promulgated for specific waters in California 
in the NTR. The specific waters to which the NTR criteria apply include: 
Waters of the State defined as bays and estuaries including San 
Francisco Bay upstream to and including Suisun Bay and the Sacramento-
San Joaquin Delta; and waters of the State defined as inland (i.e., all 
surface waters of the State not bays or estuaries or ocean) without a 
MUN use designation. This section does not apply instead of the NTR for 
these criteria.
    u. PCBs are a class of chemicals which include aroclors 1242, 1254, 
1221, 1232, 1248, 1260, and 1016, CAS numbers 53469219, 11097691, 
11104282, 11141165, 12672296, 11096825, and 12674112, respectively. The 
aquatic life criteria apply to the sum of this set of seven aroclors.
    v. This criterion applies to total PCBs, e.g., the sum of all 
congener or isomer or homolog or aroclor analyses.
    w. This criterion has been recalculated pursuant to the 1995 
Updates: Water Quality Criteria Documents for the Protection of Aquatic 
Life in Ambient Water, Office of Water, EPA-820-B-96-001, September 
1996. See also Great Lakes Water Quality Initiative Criteria Documents 
for the Protection of Aquatic Life in Ambient Water, Office of Water, 
EPA-80-B-95-004, March 1995.
    x. The State of California has adopted and EPA has approved site 
specific criteria for the Sacramento River (and tributaries) above 
Hamilton City; therefore, these criteria do not apply to these waters.

               General notes to table in paragraph (b)(1)

    1. The table in this paragraph (b)(1) lists all of EPA's priority 
toxic pollutants whether or not criteria guidance are available. Blank 
spaces indicate the absence of national section 304(a) criteria 
guidance. Because of variations in chemical nomenclature systems, this 
listing of toxic pollutants does not duplicate the listing in appendix A 
to 40 CFR Part 423-126 Priority Pollutants. EPA has added the Chemical 
Abstracts Service (CAS) registry numbers, which provide a unique 
identification for each chemical.
    2. The following chemicals have organoleptic-based criteria 
recommendations that are not included on this chart: zinc, 3-methyl-4-
chlorophenol.
    3. Freshwater and saltwater aquatic life criteria apply as specified 
in paragraph (c)(3) of this section.

    (2) Factors for Calculating Metals Criteria. Final CMC and CCC 
values should be rounded to two significant figures.

------------------------------------------------------------------------

    (c) Applicability. (1) The criteria in paragraph (b) of this section 
apply to the State's designated uses cited in paragraph (d) of this 
section and apply concurrently with any criteria adopted by the State, 
except when State regulations contain criteria which are more stringent 
for a particular parameter and use, or except as provided in footnotes 
p, q, and x to the table in paragraph (b)(1) of this section.
    (2) The criteria established in this section are subject to the 
State's general rules of applicability in the same way and to the same 
extent as are other Federally-adopted and State-adopted numeric toxics 
criteria when applied to the same use classifications including mixing 
zones, and low flow values below which numeric standards can be exceeded 
in flowing fresh waters.
    (i) For all waters with mixing zone regulations or implementation 
procedures, the criteria apply at the appropriate locations within or at 
the boundary of the mixing zones; otherwise the criteria apply 
throughout the water body including at the point of discharge into the 
water body.
    (ii) The State shall not use a low flow value below which numeric 
standards can be exceeded that is less stringent than the flows in Table 
4 to paragraph (c)(2) of this section for streams and rivers.
    (iii) Table 4 to paragraph (c)(2) of this section:

------------------------------------------------------------------------
                 Criteria                            Design flow
------------------------------------------------------------------------
Aquatic Life Acute Criteria (CMC).........  1 Q 10 or 1 B 3
Aquatic Life Chronic Criteria (CCC).......  7 Q 10 or 4 B 3
Human Health Criteria.....................  Harmonic Mean Flow
------------------------------------------------------------------------

    Note to table 4 of paragraph (c)(2):
    1. CMC (Criteria Maximum Concentration) is the water quality 
criteria to protect against acute effects in aquatic life and is the 
highest instream concentration of a priority toxic pollutant consisting 
of a short-term average not to be exceeded more than once every three 
years on the average.
    2. CCC (Continuous Criteria Concentration) is the water quality 
criteria to protect against chronic effects in aquatic life and is the 
highest in stream concentration of a priority toxic pollutant consisting 
of a 4-day average not to be exceeded more than once every three years 
on the average.
    3. 1 Q 10 is the lowest one day flow with an average recurrence 
frequency of once in 10 years determined hydrologically.

[[Page 593]]

    4. 1 B 3 is biologically based and indicates an allowable exceedence 
of once every 3 years. It is determined by EPA's computerized method 
(DFLOW model).
    5. 7 Q 10 is the lowest average 7 consecutive day low flow with an 
average recurrence frequency of once in 10 years determined 
hydrologically.
    6. 4 B 3 is biologically based and indicates an allowable exceedence 
for 4 consecutive days once every 3 years. It is determined by EPA's 
computerized method (DFLOW model).

    (iv) If the State does not have such a low flow value below which 
numeric standards do not apply, then the criteria included in paragraph 
(d) of this section apply at all flows.
    (v) If the CMC short-term averaging period, the CCC four-day 
averaging period, or once in three-year frequency is inappropriate for a 
criterion or the site to which a criterion applies, the State may apply 
to EPA for approval of an alternative averaging period, frequency, and 
related design flow. The State must submit to EPA the bases for any 
alternative averaging period, frequency, and related design flow. Before 
approving any change, EPA will publish for public comment, a document 
proposing the change.
    (3) The freshwater and saltwater aquatic life criteria in the matrix 
in paragraph (b)(1) of this section apply as follows:
    (i) For waters in which the salinity is equal to or less than 1 part 
per thousand 95% or more of the time, the applicable criteria are the 
freshwater criteria in Column B;
    (ii) For waters in which the salinity is equal to or greater than 10 
parts per thousand 95% or more of the time, the applicable criteria are 
the saltwater criteria in Column C except for selenium in the San 
Francisco Bay estuary where the applicable criteria are the freshwater 
criteria in Column B (refer to footnotes p and q to the table in 
paragraph (b)(1) of this section); and
    (iii) For waters in which the salinity is between 1 and 10 parts per 
thousand as defined in paragraphs (c)(3)(i) and (ii) of this section, 
the applicable criteria are the more stringent of the freshwater or 
saltwater criteria. However, the Regional Administrator may approve the 
use of the alternative freshwater or saltwater criteria if 
scientifically defensible information and data demonstrate that on a 
site-specific basis the biology of the water body is dominated by 
freshwater aquatic life and that freshwater criteria are more 
appropriate; or conversely, the biology of the water body is dominated 
by saltwater aquatic life and that saltwater criteria are more 
appropriate. Before approving any change, EPA will publish for public 
comment a document proposing the change.
    (4) Application of metals criteria. (i) For purposes of calculating 
freshwater aquatic life criteria for metals from the equations in 
paragraph (b)(2) of this section, for waters with a hardness of 400 mg/l 
or less as calcium carbonate, the actual ambient hardness of the surface 
water shall be used in those equations. For waters with a hardness of 
over 400 mg/l as calcium carbonate, a hardness of 400 mg/l as calcium 
carbonate shall be used with a default Water-Effect Ratio (WER) of 1, or 
the actual hardness of the ambient surface water shall be used with a 
WER. The same provisions apply for calculating the metals criteria for 
the comparisons provided for in paragraph (c)(3)(iii) of this section.
    (ii) The hardness values used shall be consistent with the design 
discharge conditions established in paragraph (c)(2) of this section for 
design flows and mixing zones.
    (iii) The criteria for metals (compounds 1--13 in the table in 
paragraph (b)(1) of this section) are expressed as dissolved except 
where otherwise noted. For purposes of calculating aquatic life criteria 
for metals from the equations in footnote i to the table in paragraph 
(b)(1) of this section and the equations in paragraph (b)(2) of this 
section, the water effect ratio is generally computed as a specific 
pollutant's acute or chronic toxicity value measured in water from the 
site covered by the standard, divided by the respective acute or chronic 
toxicity value in laboratory dilution water. To use a water effect ratio 
other than the default of 1, the WER must be determined as set forth in 
Interim Guidance on Determination and Use of Water Effect Ratios, U.S. 
EPA Office of Water,

[[Page 594]]

EPA-823-B-94-001, February 1994, or alternatively, other scientifically 
defensible methods adopted by the State as part of its water quality 
standards program and approved by EPA. For calculation of criteria using 
site-specific values for both the hardness and the water effect ratio, 
the hardness used in the equations in paragraph (b)(2) of this section 
must be determined as required in paragraph (c)(4)(ii) of this section. 
Water hardness must be calculated from the measured calcium and 
magnesium ions present, and the ratio of calcium to magnesium should be 
approximately the same in standard laboratory toxicity testing water as 
in the site water.
    (d)(1) Except as specified in paragraph (d)(3) of this section, all 
waters assigned any aquatic life or human health use classifications in 
the Water Quality Control Plans for the various Basins of the State 
(``Basin Plans'') adopted by the California State Water Resources 
Control Board (``SWRCB''), except for ocean waters covered by the Water 
Quality Control Plan for Ocean Waters of California (``Ocean Plan'') 
adopted by the SWRCB with resolution Number 90-27 on March 22, 1990, are 
subject to the criteria in paragraph (d)(2) of this section, without 
exception. These criteria apply to waters identified in the Basin Plans. 
More particularly, these criteria apply to waters identified in the 
Basin Plan chapters designating beneficial uses for waters within the 
region. Although the State has adopted several use designations for each 
of these waters, for purposes of this action, the specific standards to 
be applied in paragraph (d)(2) of this section are based on the presence 
in all waters of some aquatic life designation and the presence or 
absence of the MUN use designation (municipal and domestic supply). (See 
Basin Plans for more detailed use definitions.)
    (2) The criteria from the table in paragraph (b)(1) of this section 
apply to the water and use classifications defined in paragraph (d)(1) 
of this section as follows:

------------------------------------------------------------------------
      Water and use classification             Applicable criteria
------------------------------------------------------------------------
(i) All inland waters of the United      (A) Columns B1 and B2--all
 States or enclosed bays and estuaries    pollutants
 that are waters of the United States    (B) Columns C1 and C2--all
 that include a MUN use designation.      pollutants
                                         (C) Column D1--all pollutants
------------------------------------------------------------------------
(ii) All inland waters of the United     (A) Columns B1 and B2--all
 States or enclosed bays and estuaries    pollutants
 that are waters of the United States    (B) Columns C1 and C2--all
 that do not include a MUN use            pollutants
 designation.                            (C) Column D2--all pollutants
------------------------------------------------------------------------

    (3) Nothing in this section is intended to apply instead of specific 
criteria, including specific criteria for the San Francisco Bay estuary, 
promulgated for California in the National Toxics Rule at Sec. 131.36.
    (4) The human health criteria shall be applied at the State-adopted 
10 (-6) risk level.
    (5) Nothing in this section applies to waters located in Indian 
Country.
    (e) Schedules of compliance. (1) It is presumed that new and 
existing point source dischargers will promptly comply with any new or 
more restrictive water quality-based effluent limitations (``WQBELs'') 
based on the water quality criteria set forth in this section.
    (2) When a permit issued on or after May 18, 2000 to a new 
discharger contains a WQBEL based on water quality criteria set forth in 
paragraph (b) of this section, the permittee shall comply with such 
WQBEL upon the commencement of the discharge. A new discharger is 
defined as any building, structure, facility, or installation from which 
there is or may be a ``discharge of pollutants'' (as defined in 40 CFR 
122.2) to the State of California's inland surface waters or enclosed 
bays and estuaries, the construction of which commences after May 18, 
2000.
    (3) Where an existing discharger reasonably believes that it will be 
infeasible to promptly comply with a new or more restrictive WQBEL based 
on the

[[Page 595]]

water quality criteria set forth in this section, the discharger may 
request approval from the permit issuing authority for a schedule of 
compliance.
    (4) A compliance schedule shall require compliance with WQBELs based 
on water quality criteria set forth in paragraph (b) of this section as 
soon as possible, taking into account the dischargers' technical ability 
to achieve compliance with such WQBEL.
    (5) If the schedule of compliance exceeds one year from the date of 
permit issuance, reissuance or modification, the schedule shall set 
forth interim requirements and dates for their achievement. The dates of 
completion between each requirement may not exceed one year. If the time 
necessary for completion of any requirement is more than one year and is 
not readily divisible into stages for completion, the permit shall 
require, at a minimum, specified dates for annual submission of progress 
reports on the status of interim requirements.
    (6) In no event shall the permit issuing authority approve a 
schedule of compliance for a point source discharge which exceeds five 
years from the date of permit issuance, reissuance, or modification, 
whichever is sooner. Where shorter schedules of compliance are 
prescribed or schedules of compliance are prohibited by law, those 
provisions shall govern.
    (7) If a schedule of compliance exceeds the term of a permit, 
interim permit limits effective during the permit shall be included in 
the permit and addressed in the permit's fact sheet or statement of 
basis. The administrative record for the permit shall reflect final 
permit limits and final compliance dates. Final compliance dates for 
final permit limits, which do not occur during the term of the permit, 
must occur within five years from the date of issuance, reissuance or 
modification of the permit which initiates the compliance schedule. 
Where shorter schedules of compliance are prescribed or schedules of 
compliance are prohibited by law, those provisions shall govern.
    (8) The provisions in this paragraph (e), Schedules of compliance, 
shall expire on May 18, 2005.

    (b) Criteria that apply to Puerto Rico's marine waters. In addition 
to all other Commonwealth criteria, the following criteria for bacteria 
apply to the waterbodies in paragraph (a) of this section:
    Bacteria: The fecal coliform geometric mean of a series of 
representative samples (at least five samples) of the waters taken 
sequentially shall not exceed 200 colonies/100 ml, and not more than 20 
percent of the samples

[[Page 596]]

shall exceed 400 colonies/100 ml. The enterococci density in terms of 
geometric mean of at least five representative samples taken 
sequentially shall not exceed 35/100 ml. No single sample should exceed 
the upper confidence limit of 75% using 0.7 as the log standard 
deviation until sufficient site data exist to establish a site-specific 
log standard deviation.
    (c) Water quality standard variances. The Regional Administrator, 
EPA Region 2, is authorized to grant variances from the water quality 
standards in paragraphs (a) and (b) of this section where the 
requirements of Sec. 131.14 are met.

Sec. 131.41  Bacteriological criteria for those states not complying
with Clean Water Act section 303(i)(1)(A).

    (a) Scope. This section is a promulgation of the Clean Water Act 
section 304(a) criteria for bacteria for coastal recreation waters in 
specific States. It is not a general promulgation of the Clean Water Act 
section 304(a) criteria for bacteria. This section also contains a 
compliance schedule provision.
    (b) Definitions. (1) Coastal Recreation Waters are the Great Lakes 
and marine coastal waters (including coastal estuaries) that are 
designated under section 303(c) of the Clean Water Act for use for 
swimming, bathing, surfing, or similar water contact activities. Coastal 
recreation waters do not include inland waters or waters upstream from 
the mouth of a river or stream having an unimpaired natural connection 
with the open sea.
    (2) Designated bathing beach waters are those coastal recreation 
waters that, during the recreation season, are heavily-used (based upon 
an evaluation of use within the State) and may have: a lifeguard, 
bathhouse facilities, or public parking for beach access. States may 
include any other waters in this category even if the waters do not meet 
these criteria.
    (3) Moderate use coastal recreation waters are those coastal 
recreation waters that are not designated bathing beach waters but 
typically, during the recreation season, are used by at least half of 
the number of people as at typical designated bathing beach waters 
within the State. States may also include light use or infrequent use 
coastal recreation waters in this category.
    (4) Light use coastal recreation waters are those coastal recreation 
waters that are not designated bathing beach waters but typically, 
during the recreation season, are used by less than half of the number 
of people as at typical designated bathing beach waters within the 
State, but are more than infrequently used. States may also include 
infrequent use coastal recreation waters in this category.
    (5) Infrequent use coastal recreation waters are those coastal 
recreation waters that are rarely or occasionally used.
    (6) New pathogen discharger for the purposes of this section means 
any building, structure, facility, or installation from which there is 
or may be a discharge of pathogens, the construction of which commenced 
on or after December 16, 2004. It does not include relocation of 
existing combined sewer overflow outfalls.
    (7) Existing pathogen discharger for the purposes of this section 
means any discharger that is not a new pathogen discharger.

    (3) As an alternative to the single sample maximum in paragraph 
(c)(1) or (c)(2) of this section, States may use a site-specific log 
standard deviation to calculate a single sample maximum for individual 
coastal recreation waters, but must use at least 30 samples from a 
single recreation season to do so.
    (d) Applicability. (1) The criteria in paragraph (c) of this section 
apply to the coastal recreation waters of the States identified in 
paragraph (e) of this section and apply concurrently with any ambient 
recreational water criteria adopted by the State, except for those 
coastal recreation waters where State regulations determined by EPA to 
meet the requirements of Clean Water Act section 303(i) apply, in which 
case the State's criteria for those coastal recreation waters will apply 
and not the criteria in paragraph (c) of this section.
    (2) The criteria established in this section are subject to the 
State's general rules of applicability in the same way and to the same 
extent as are other Federally-adopted and State-adopted numeric criteria 
when applied to the same use classifications.
    (e) Applicability to specific jurisdictions. (1) The criteria in 
paragraph (c)(1) of this section apply to fresh coastal recreation 
waters of the following States: Illinois, Minnesota, New York, Ohio, 
Pennsylvania, Wisconsin.
    (2) The criteria in paragraph (c)(2) of this section apply to marine 
coastal recreation waters of the following States: Alaska, California 
(except for coastal recreation waters within the jurisdiction of 
Regional Board 4), Florida, Georgia, Hawaii (except for coastal 
recreation waters within 300 meters of the shoreline), Louisiana, Maine 
(except for SA waters and SB and SC waters with human sources of fecal 
contamination), Maryland, Massachusetts, Mississippi, New York, North 
Carolina, Oregon, Puerto Rico (except for waters classified by Puerto 
Rico as intensely used for primary contact recreation and for those 
waters included in Sec. 131.40), Rhode Island, United States Virgin 
Islands.
    (f) Schedules of compliance. (1) This paragraph (f) applies to any 
State that does not have a regulation in effect for Clean Water Act 
purposes that authorizes compliance schedules for National Pollutant 
Discharge Elimination System permit limitations needed to meet the 
criteria in paragraph (c) of this section. All dischargers shall 
promptly comply with any new or more restrictive water quality-based 
effluent limitations based on the water quality criteria set forth in 
this section.

[[Page 598]]

    (2) When a permit issued on or after December 16, 2004, to a new 
pathogen discharger as defined in paragraph (b) of this section contains 
water quality-based effluent limitations based on water quality criteria 
set forth in paragraph (c) of this section, the permittee shall comply 
with such water quality-based effluent limitations upon the commencement 
of the discharge.
    (3) Where an existing pathogen discharger reasonably believes that 
it will be infeasible to comply immediately with a new or more 
restrictive water quality-based effluent limitations based on the water 
quality criteria set forth in paragraph (c) of this section, the 
discharger may request approval from the permit issuing authority for a 
schedule of compliance.
    (4) A compliance schedule for an existing pathogen discharger shall 
require compliance with water quality-based effluent limitations based 
on water quality criteria set forth in paragraph (c) of this section as 
soon as possible, taking into account the discharger's ability to 
achieve compliance with such water quality-based effluent limitations.
    (5) If the schedule of compliance for an existing pathogen 
discharger exceeds one year from the date of permit issuance, reissuance 
or modification, the schedule shall set forth interim requirements and 
dates for their achievement. The period between dates of completion for 
each requirement may not exceed one year.
    If the time necessary for completion of any requirement is more than 
one year and the requirement is not readily divisible into stages for 
completion, the permit shall require, at a minimum, specified dates for 
annual submission of progress reports on the status of interim 
requirements.
    (6) In no event shall the permit issuing authority approve a 
schedule of compliance for an existing pathogen discharge which exceeds 
five years from the date of permit issuance, reissuance, or 
modification, whichever is sooner.
    (7) If a schedule of compliance exceeds the term of a permit, 
interim permit limits effective during the permit shall be included in 
the permit and addressed in the permit's fact sheet or statement of 
basis. The administrative record for the permit shall reflect final 
permit limits and final compliance dates. Final compliance dates for 
final permit limits, which do not occur during the term of the permit, 
must occur within five years from the date of issuance, reissuance or 
modification of the permit which initiates the compliance schedule.

Sec. 131.42  Antidegradation Implementation Methods for the Commonwealth
of Puerto Rico.

    (a) General Policy Statement. (1) All point sources of pollution are 
subject to an antidegradation review.
    (2) An antidegradation review shall be initiated as part of the 
Section 401--``Water Quality Certification Process'' of the Clean Water 
Act.
    (3) The 401 Certification Process shall follow the procedures 
established by the February 2, 1989 Resolution R-89-2-2 of the Governing 
Board of the Puerto Rico Environmental Quality Board (EQB).
    (4) The following are not subject to an antidegradation review due 
to the fact that they are nondischarge systems and are managed by 
specific applicable Puerto Rico regulations:
    (i) All nonpoint sources of pollutants.
    (ii) Underground Storage Tanks.
    (iii) Underground Injection Facilities.
    (5) The protection of water quality shall include the maintenance, 
migration, protection, and propagation of desirable species, including 
threatened and endangered species identified in the local and federal 
regulations.
    (b) Definitions. (1) All the definitions included in Article 1 of 
the Puerto Rico Water Quality Standards Regulation (PRWQSR), as amended, 
are applicable to this procedure.
    (2) High Quality Waters:
    (i) Are waters whose quality is better than the mandatory minimum 
level to support the CWA Section 101(a)(2) goals of propagation of fish, 
shellfish, wildlife and recreation in and on the waters. High Quality 
Waters are to be identified by EQB on a parameter-by-parameter basis.
    (ii) [Reserved]

[[Page 599]]

    (3) Outstanding National Resources Waters (ONRWs):
    (i) Are waters classified as SA or SE in the PRWQSR, as amended, or 
any other water designated by Resolution of the Governing Board of EQB. 
ONRWs are waters that are recreationally or ecologically important, 
unique or sensitive.
    (ii) [Reserved]
    (c) Antidegradation Review Procedure. (1) The antidegradation review 
will commence with the submission of the CWA Section 401 water quality 
certification request. EQB uses a parameter-by-parameter approach for 
the implementation of the anti-degradation policy and will review each 
parameter separately as it evaluates the request for certification. The 
401 certification/antidegradation review shall comply with Article 
4(B)(3) of the Puerto Rico Environmental Public Policy Act (Law No. 416 
of September 22, 2004, as amended (12 LPRA 8001 et seq.)). Compliance 
with Article 4(B)(3) shall be conducted in accordance with the 
Reglamento de la Junta de Calidad Ambiental para el Proceso de 
Presentaci[oacute]n, Evaluaci[oacute]n y Tr[aacute]mite de Documentos 
Ambientales (EQB's Environmental Documents Regulation). As part of the 
evaluation of the Environmental Document an alternatives analysis shall 
be conducted (12 LPRA 8001(a)(5), EQB's Environmental Documents 
Regulation, e.g., Rules 211E and 253C), and a public participation 
period and a public hearing shall be provided (12 LPRA 8001(a), EQB's 
Environmental Documents Regulation, Rule 254).
    (2) In conducting an antidegradation review, EQB will sequentially 
apply the following steps:
    (i) Determine which level of antidegradation applies
    (A) Tier 1--Protection of Existing and Designated Uses.
    (B) Tier 2--Protection of High Quality Waters.
    (C) Tier 3--Protection of ONRWs.
    (ii) [Reserved]
    (3) Review existing water quality data and other information 
submitted by the applicant. The applicant shall provide EQB with the 
information regarding the discharge, as required by the PRWQSR 
including, but not limited to the following:
    (i) A description of the nature of the pollutants to be discharged.
    (ii) Treatment technologies applied to the pollutants to be 
discharged.
    (iii) Nature of the applicant's business.
    (iv) Daily maximum and average flow to be discharged.
    (v) Effluent characterization.
    (vi) Effluent limitations requested to be applied to the discharge 
according to Section 6.11 of the PRWQSR.
    (vii) Location of the point of discharge.
    (viii) Receiving waterbody name.
    (ix) Water quality data of the receiving waterbody.
    (x) Receiving waterbody minimum flow (7Q2 and 7Q10) for stream 
waters.
    (xi) Location of water intakes within the waterbody.
    (xii) In the event that the proposed discharge will result in the 
lowering of water quality, data and information demonstrating that the 
discharge is necessary to accommodate important economic or social 
development in the area where the receiving waters are located.
    (4) Determine if additional information or assessment is necessary 
to make the decision.
    (5) Prepare an intent to issue or deny the 401 water quality 
certificate and publish a notice in a newspaper of wide circulation in 
Puerto Rico informing the public of EQB's preliminary decision and 
granting a public participation period of at least thirty (30) days.
    (6) Address the comments received from the interested parties and 
consider such comments as part of the decision making process.
    (7) Make the final determination to issue or deny the requested 401 
certification. Such decision is subject to the reconsideration procedure 
established in Law 170 of August 12, 1988, Ley de Procedimiento 
Administrativo Uniforme del Estado Libre Asociado de Puerto Rico (3 LPRA 
2165).
    (d) Implementation Procedures. (1) Activities Regulated by NPDES 
Permits
    (i) Tier 1--Protection of Existing and Designated Uses:
    (A) Tier 1 waters are:
    (1) Those waters of Puerto Rico (except Tier 2 or Tier 3 waters) 
identified

[[Page 600]]

as impaired and that have been included on the list required by Section 
303(d) of the CWA; and
    (2) Those waters of Puerto Rico (except Tier 2 and Tier 3 waters) 
for which attainment of applicable water quality standards has been or 
is expected to be, achieved through implementation of effluent 
limitations more stringent than technology-based controls (Best 
Practicable Technology, Best Available Technology and Secondary 
Treatment).
    (B) To implement Tier 1 antidegradation, EQB shall determine if a 
discharge would lower the water quality to the extent that it would no 
longer be sufficient to protect and maintain the existing and designated 
uses of that waterbody.
    (C) When a waterbody has been affected by a parameter of concern 
causing it to be included on the 303(d) List, then EQB will not allow an 
increase of the concentration of the parameter of concern or pollutants 
affecting the parameter of concern in the waterbody. This no increase 
will be achieved by meeting the applicable water quality standards at 
the end of the pipe. Until such time that a Total Maximum Daily Load 
(TMDL) is developed for the parameter of concern for the waterbody, no 
discharge will be allowed to cause or contribute to further degradation 
of the waterbody.
    (D) When the assimilative capacity of a waterbody is not sufficient 
to ensure maintenance of the water quality standard for a parameter of 
concern with an additional load to the waterbody, EQB will not allow an 
increase of the concentration of the parameter of concern or pollutants 
affecting the parameter of concern in the waterbody. This no increase 
will be achieved by meeting the applicable water quality standards at 
the end of the pipe. Until such time that a TMDL is developed for the 
parameter of concern for the waterbody, no discharge will be allowed to 
cause or contribute to further degradation of the waterbody.
    (ii) Tier 2--Protection of High Quality Waters:
    (A) To verify that a waterbody is a high quality water for a 
parameter of concern which initiates a Tier 2 antidegradation review, 
EQB shall evaluate and determine:
    (1) The existing water quality of the waterbody;
    (2) The projected water quality of the waterbody pursuant to the 
procedures established in the applicable provisions of Articles 5 and 10 
of the PRWQSR including but not limited to, Sections 5.2, 5.3, 5.4, 
10.2, 10.3, 10.4, 10.5, and 10.6;
    (3) That the existing and designated uses of the waterbody will be 
fully maintained and protected in the event of a lowering of water 
quality.
    In multiple discharge situations, the effects of all discharges 
shall be evaluated through a waste load allocation analysis in 
accordance with the applicable provisions of Article 10 of the PRWQSR or 
the applicable provisions of Article 5 regarding mixing zones.
    (B) In order to allow the lowering of water quality in high quality 
waters, the applicant must show and justify the necessity for such 
lowering of water quality through compliance with the requirements of 
Section 6.11 of the PRWQSR. EQB will not allow the entire assimilative 
capacity of a waterbody for a parameter of concern to be allocated to a 
discharger, if the necessity of the requested effluent limitation for 
the parameter of concern is not demonstrated to the full satisfaction of 
EQB.
    (iii) Tier 3--Protection of ONRWs:
    (A) EQB may designate a water as Class SA or SE (ONRWs) through a 
Resolution (PRWQSR Sections 2.1.1 and 2.2.1). Additionally, any 
interested party may nominate a specific water to be classified as an 
ONRW and the Governing Board of EQB will make the final determination. 
Classifying a water as an ONRW may result in the water being named in 
either Section 2.1.1 or 2.2.2 of the PRWQSR, which would require an 
amendment of the PRWQSR. The process for amending the PRWQSR, including 
public participation, is set forth in Section 8.6 of said regulation.
    (B) The existing characteristics of Class SA and SE waters shall not 
be altered, except by natural causes, in order to preserve the existing 
natural phenomena.
    (1) No point source discharge will be allowed in ONRWs.

[[Page 601]]

    (2) [Reserved]
    (2) Activities Regulated by CWA Section 404 or Rivers and Harbors 
Action Section 10 Permits (Discharge of Dredged or Fill Material)
    (i) EQB will only allow the discharge of dredged or fill material 
into a wetland if it can be demonstrated that such discharge will not 
have an unacceptable adverse impact either individually or in 
combination with other activities affecting the wetland of concern. The 
impacts to the water quality or the aquatic or other life in the wetland 
due to the discharge of dredged or fill material should be avoided, 
minimized and mitigated.
    (ii) The discharge of dredged or fill material shall not be 
certified if there is a practicable alternative to the proposed 
discharge which would have less adverse impact on the recipient 
ecosystem, so long as the alternative does not have other more 
significant adverse environmental consequences. Activities which are not 
water dependent are presumed to have practicable alternatives, unless 
the applicant clearly demonstrates otherwise. No discharge of dredged 
and fill material shall be certified unless appropriate and practicable 
steps have been taken which minimize potential adverse impacts of the 
discharge on the recipient ecosystem. The discharge of dredged or fill 
material to ONRWs, however, shall be governed by paragraph (d)(1)(iii) 
of this section.

\a\ This criterion is expressed as the fish tissue concentration of methylmercury (mg methylmercury/kg fish) and
  applies equally to fresh and marine waters.
\b\ This criterion applies to total PCBs (i.e., the sum of all congener or isomer or homolog or Aroclor
  analyses).

    (b) Bacteria criteria for waters in Indian lands. (1) The bacteria 
content of Class AA and Class A waters shall be as naturally occurs, and 
the minimum number of Escherichia coli bacteria shall not exceed a

    (4) In Class SA shellfish harvesting areas, the numbers of total 
coliform bacteria or other specified indicator organisms in samples 
representative of the waters in shellfish harvesting areas may not 
exceed the criteria recommended under the National Shellfish Sanitation 
Program, United States Food and Drug Administration, as set forth in the 
Guide for the Control of Molluscan Shellfish, 2015 Revision. The 
Director of the Federal Register approves this incorporation by

    (d) pH Criteria for fresh waters in Indian lands. The pH of fresh 
waters shall fall within the range of 6.5 to 8.5.
    (e) Temperature criteria for tidal waters in Indian lands. (1) The 
maximum acceptable cumulative increase in the weekly average temperature 
resulting

[[Page 607]]

from all artificial sources is 1 [deg]C (1.8 [deg]F) during all seasons 
of the year, provided that the summer maximum is not exceeded.
    (i) Weekly average temperature increase shall be compared to 
baseline thermal conditions and shall be calculated using the daily 
maxima averaged over a 7-day period.
    (ii) Baseline thermal conditions shall be measured at or modeled 
from a site where there is no artificial thermal addition from any 
source, and which is in reasonable proximity to the thermal discharge 
(within 5 miles), and which has similar hydrography to that of the 
receiving waters at the discharge.
    (2) Natural temperature cycles characteristic of the waterbody 
segment shall not be altered in amplitude or frequency.
    (3) During the summer months (for the period from May 15 through 
September 30), water temperatures shall not exceed a weekly average 
summer maximum threshold of 18 [deg]C (64.4 [deg]F) (calculated using 
the daily maxima averaged over a 7-day period).
    (f) Natural conditions provisions for waters in Indian lands. (1) 
The provision in Title 38 of Maine Revised Statutes 464(4.C) which 
reads: ``Where natural conditions, including, but not limited to, 
marshes, bogs and abnormal concentrations of wildlife cause the 
dissolved oxygen or other water quality criteria to fall below the 
minimum standards specified in section 465, 465-A and 465-B, those 
waters shall not be considered to be failing to attain their 
classification because of those natural conditions,'' does not apply to 
water quality criteria intended to protect human health.
    (2) The provision in Title 38 of Maine Revised Statutes 420(2.A) 
which reads ``Except as naturally occurs or as provided in paragraphs B 
and C, the board shall regulate toxic substances in the surface waters 
of the State at the levels set forth in federal water quality criteria 
as established by the United States Environmental Protection Agency 
pursuant to the Federal Water Pollution Control Act, Public Law 92-500, 
Section 304(a), as amended,'' does not apply to water quality criteria 
intended to protect human health.
    (g) Mixing zone policy for waters in Indian lands. (1) Establishing 
a mixing zone. (i) The Department of Environmental Protection 
(``department'') may establish a mixing zone for any discharge at the 
time of application for a waste discharge license if all of the 
requirements set forth in paragraphs (g)(2) and (3) of this section are 
satisfied. The department shall attach a description of the mixing zone 
as a condition of a license issued for that discharge. After opportunity 
for a hearing in accordance with 38 MRS section 345-A, the department 
may establish by order a mixing zone with respect to any discharge for 
which a license has been issued pursuant to section 414 or for which an 
exemption has been granted by virtue of 38 MRS section 413, subsection 
2.
    (ii) The purpose of a mixing zone is to allow a reasonable 
opportunity for dilution, diffusion, or mixture of pollutants with the 
receiving waters such that an applicable criterion may be exceeded 
within a defined area of the waterbody while still protecting the 
designated use of the waterbody as a whole. In determining the extent of 
any mixing zone to be established under this section, the department 
will require from the applicant information concerning the nature and 
rate of the discharge; the nature and rate of existing discharges to the 
waterway; the size of the waterway and the rate of flow therein; any 
relevant seasonal, climatic, tidal, and natural variations in such size, 
flow, nature, and rate; the uses of the waterways that could be affected 
by the discharge, and such other and further evidence as in the 
department's judgment will enable it to establish a reasonable mixing 
zone for such discharge. An order establishing a mixing zone may provide 
that the extent thereof varies in order to take into account seasonal, 
climatic, tidal, and natural variations in the size and flow of, and the 
nature and rate of, discharges to the waterway.
    (2) Mixing zone information requirements. At a minimum, any request 
for a mixing zone must:
    (i) Describe the amount of dilution occurring at the boundaries of 
the proposed mixing zone and the size, shape,

[[Page 608]]

and location of the area of mixing, including the manner in which 
diffusion and dispersion occur;
    (ii) Define the location at which discharge-induced mixing ceases;
    (iii) Document the substrate character and geomorphology within the 
mixing zone;
    (iv) Document background water quality concentrations;
    (v) Address the following factors;
    (A) Whether adjacent mixing zones overlap;
    (B) Whether organisms would be attracted to the area of mixing as a 
result of the effluent character; and
    (C) Whether the habitat supports endemic or naturally occurring 
species.
    (vi) Provide all information necessary to demonstrate whether the 
requirements in paragraph (g)(3) of this section are satisfied.
    (3) Mixing zone requirements. (i) Mixing zones shall be established 
consistent with the methodologies in Sections 4.3 and 4.4 of the 
``Technical Support Document for Water Quality-based Toxics Control'' 
EPA/505/2-90-001, dated March 1991.
    (ii) The mixing zone demonstration shall be based on the assumption 
that a pollutant does not degrade within the proposed mixing zone, 
unless:
    (A) Scientifically valid field studies or other relevant information 
demonstrate that degradation of the pollutant is expected to occur under 
the full range of environmental conditions expected to be encountered; 
and
    (B) Scientifically valid field studies or other relevant information 
address other factors that affect the level of pollutants in the water 
column including, but not limited to, resuspension of sediments, 
chemical speciation, and biological and chemical transformation.
    (iii) Water quality within an authorized mixing zone is allowed to 
exceed chronic water quality criteria for those parameters approved by 
the department. Acute water quality criteria may be exceeded for such 
parameters within the zone of initial dilution inside the mixing zone. 
Acute criteria shall be met as close to the point of discharge as 
practicably attainable. Water quality criteria shall not be violated 
outside of the boundary of a mixing zone as a result of the discharge 
for which the mixing zone was authorized.
    (iv) Mixing zones shall be as small as practicable. The 
concentrations of pollutants present shall be minimized and shall 
reflect the best practicable engineering design of the outfall to 
maximize initial mixing. Mixing zones shall not be authorized for 
bioaccumulative pollutants (i.e., chemicals for which the 
bioconcentration factors (BCF) or bioaccumulation factors (BAF) are 
greater than 1,000) or bacteria.
    (v) In addition to the requirements above, the department may 
approve a mixing zone only if the mixing zone:
    (A) Is sized and located to ensure that there will be a continuous 
zone of passage that protects migrating, free-swimming, and drifting 
organisms;
    (B) Will not result in thermal shock or loss of cold water habitat 
or otherwise interfere with biological communities or populations of 
indigenous species;
    (C) Is not likely to jeopardize the continued existence of any 
endangered or threatened species listed under section 4 of the 
Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.) or 
result in the destruction or adverse modification of such species' 
critical habitat;
    (D) Will not extend to drinking water intakes and sources;
    (E) Will not otherwise interfere with the designated or existing 
uses of the receiving water or downstream waters;
    (F) Will not promote undesirable aquatic life or result in a 
dominance of nuisance species;
    (G) Will not endanger critical areas such as breeding and spawning 
grounds, habitat for state-listed threatened or endangered species, 
areas with sensitive biota, shellfish beds, fisheries, and recreational 
areas;
    (H) Will not contain pollutant concentrations that are lethal to 
mobile, migrating, and drifting organisms passing through the mixing 
zone;
    (I) Will not contain pollutant concentrations that may cause 
significant human health risks considering likely pathways of exposure;
    (J) Will not result in an overlap with another mixing zone;
    (K) Will not attract aquatic life;

[[Page 609]]

    (L) Will not result in a shore-hugging plume; and
    (M) Is free from:
    (1) Substances that settle to form objectionable deposits;
    (2) Floating debris, oil, scum, and other matter in concentrations 
that form nuisances; and
    (3) Objectionable color, odor, taste, or turbidity.
    (h) Dissolved oxygen criteria for class A waters throughout the 
State of Maine, including in Indian lands. The dissolved oxygen content 
of Class A waters shall not be less than 7 ppm (7 mg/L) or 75% of 
saturation, whichever is higher, year-round. For the period from October 
1 through May 14, in fish spawning areas, the 7-day mean dissolved 
oxygen concentration shall not be less than 9.5 ppm (9.5 mg/L), and the 
1-day minimum dissolved oxygen concentration shall not be less than 8 
ppm (8.0 mg/L).
    (i) Waiver or modification of protection and improvement laws for 
waters throughout the State of Maine, including in Indian lands. For all 
waters in Maine, the provisions in Title 38 of Maine Revised Statutes 
363-D do not apply to state or federal water quality standards 
applicable to waters in Maine, including designated uses, criteria to 
protect existing and designated uses, and antidegradation policies.
    (j) Phenol criterion for the protection of human health for Maine 
waters outside of Indian lands. The phenol criterion to protect human 
health for the consumption of water and organisms is 4000 micrograms per 
liter.

\a\ This criterion refers to the inorganic form of arsenic only.
\b\ This criterion is expressed as the fish tissue concentration of methylmercury (mg methylmercury/kg fish). See Water Quality Criterion for the
  Protection of Human Health: Methylmercury (EPA-823-R-01-001, January 3, 2001) for how this value is calculated using the criterion equation in EPA's
  2000 Human Health Methodology rearranged to solve for a protective concentration in fish tissue rather than in water.
\c\ This criterion applies to total PCBs (e.g., the sum of all congener or isomer or homolog or Aroclor analyses).
* Bis(2-Chloro-1-Methylethyl) Ether was previously listed as Bis(2-Chloroisopropyl) Ether.
** These criteria were promulgated for Washington in the National Toxics Rule at 40 CFR 131.36, and are moved into 40 CFR 131.45 to have one
  comprehensive human health criteria rule for Washington.


[[Page 614]]

    (c) Applicability. (1) The criteria in paragraph (b) of this section 
apply to waters with Washington's designated uses cited in paragraph (d) 
of this section and apply concurrently with other applicable water 
quality criteria.
    (2) The criteria established in this section are subject to 
Washington's general rules of applicability in the same way and to the 
same extent as are other federally promulgated and state-adopted numeric 
criteria when applied to the same use classifications in paragraph (d) 
of this section.
    (i) For all waters with mixing zone regulations or implementation 
procedures, the criteria apply at the appropriate locations within or at 
the boundary of the mixing zones; otherwise the criteria apply 
throughout the waterbody including at the end of any discharge pipe, 
conveyance or other discharge point within the waterbody.
    (ii) The state must not use a low flow value below which numeric 
non-carcinogen and carcinogen human health criteria can be exceeded that 
is less stringent than the harmonic mean flow for waters suitable for 
the establishment of low flow return frequencies (i.e., streams and 
rivers). Harmonic mean flow is a long-term mean flow value calculated by 
dividing the number of daily flows analyzed by the sum of the 
reciprocals of those daily flows.
    (iii) If the state does not have such a low flow value for numeric 
criteria, then none will apply and the criteria in paragraph (b) of this 
section herein apply at all flows.
    (d) Applicable use designations. (1) All waters in Washington 
assigned to the following use classifications are subject to the 
criteria identified in paragraph (d)(2) of this section:
    (i) Fresh waters--
    (A) Miscellaneous uses: Harvesting (Fish harvesting);
    (B) Recreational uses;
    (C) Water supply uses: Domestic water (Domestic water supply);
    (ii) Marine waters--
    (A) Miscellaneous uses: Harvesting (Salmonid and other fish 
harvesting, and crustacean and other shellfish (crabs, shrimp, scallops, 
etc.) harvesting);
    (B) Recreational uses;
    (C) Shellfish harvesting: Shellfish harvest (Shellfish (clam, 
oyster, and mussel) harvesting)

    Note to paragraph (d)(1):
    The source of these uses is Washington Administrative Code 173-201A-
600 for Fresh waters and 173-201A-610 for Marine waters.

    (2) For Washington waters that include the use classification of 
Domestic Water, the criteria in column C1 and the methylmercury 
criterion in column C2 of Table 1 in paragraph (b) of this section 
apply. For Washington waters that include any of the following use 
classifications but do not include the use classification of Domestic 
Water, the criteria in column C2 of Table 1 in paragraph (b) of this 
section apply: Harvesting (fresh and marine waters), Recreational Uses 
(fresh and marine waters), and Shellfish Harvesting.

Sec. 131.46  Aquatic life criterion for cadmium in Oregon.

    (a) Scope. This section promulgates an acute aquatic life criterion 
for cadmium in freshwaters in Oregon.
    (b) Criterion for cadmium in Oregon. The aquatic life criterion in 
Table 1 applies to all freshwaters in Oregon where fish and aquatic life 
are a designated use.

\1\ The criterion for cadmium is expressed as the dissolved metal
  concentration.
\2\ CF is the conversion factor used to convert between the total
  recoverable and dissolved forms of cadmium. The term (ln hardness) in
  the CMC and the CF equation is the natural logarithm of the ambient
  hardness in mg/L (CaCO3). The default hardness concentrations from the
  applicable ecoregion in Table 2 of paragraph (c) of this section shall
  be used to calculate cadmium criteria in the absence of sufficiently
  representative ambient hardness data.
\3\ The CMC is the highest allowable one-hour average instream
  concentration of cadmium. The CMC is not to be exceeded more than once
  every three years. The CMC is rounded to two significant figures.

Sec. 132.1  Scope, purpose, and availability of documents.

    (a) This part constitutes the Water Quality Guidance for the Great 
Lakes System (Guidance) required by section 118(c)(2) of the Clean Water 
Act (33 U.S.C. 1251 et seq.) as amended by the Great Lakes Critical 
Programs Act of 1990 (Pub. L. 101-596, 104 Stat. 3000 et

[[Page 616]]

seq.). The Guidance in this part identifies minimum water quality 
standards, antidegradation policies, and implementation procedures for 
the Great Lakes System to protect human health, aquatic life, and 
wildlife.
    (b) The U.S. Environmental Protection Agency, Great Lakes States, 
and Great Lakes Tribes will use the Guidance in this part to evaluate 
the water quality programs of the States and Tribes to assure that they 
are protective of water quality. State and Tribal programs do not need 
to be identical to the Guidance in this part, but must contain 
provisions that are consistent with (as protective as) the Guidance in 
this part. The scientific, policy and legal basis for EPA's development 
of each section of the final Guidance in this part is set forth in the 
preamble, Supplementary Information Document, Technical Support 
Documents, and other supporting documents in the public docket. EPA will 
follow the guidance set out in these documents in reviewing the State 
and Tribal water quality programs in the Great Lakes for consistency 
with this part.
    (c) The Great Lakes States and Tribes must adopt provisions 
consistent with the Guidance in this part applicable to waters in the 
Great Lakes System or be subject to EPA promulgation of its terms 
pursuant to this part.
    (d) EPA understands that the science of risk assessment is rapidly 
improving. Therefore, to ensure that the scientific basis for the 
methodologies in appendices A through D are always current and peer 
reviewed, EPA will review the methodologies and revise them, as 
appropriate, every 3 years.
    (e) Certain documents referenced in the appendixes to this part with 
a designation of NTIS and/or ERIC are available for a fee upon request 
to the National Technical Information Center (NTIS), U.S. Department of 
Commerce, 5285 Port Royal Road, Springfield, VA 22161. Alternatively,

CSMEE accession number.



Sec. 132.2  Definitions.

    The following definitions apply in this part. Terms not defined in 
this section have the meaning given by the Clean Water Act and EPA 
implementing regulations.
    Acute-chronic ratio (ACR) is a standard measure of the acute 
toxicity of a material divided by an appropriate measure of the chronic 
toxicity of the same material under comparable conditions.
    Acute toxicity is concurrent and delayed adverse effect(s) that 
results from an acute exposure and occurs within any short observation 
period which begins when the exposure begins, may extend beyond the 
exposure period, and usually does not constitute a substantial portion 
of the life span of the organism.
    Adverse effect is any deleterious effect to organisms due to 
exposure to a substance. This includes effects which are or may become 
debilitating, harmful or toxic to the normal functions of the organism, 
but does not include non-harmful effects such as tissue discoloration 
alone or the induction of enzymes involved in the metabolism of the 
substance.
    Bioaccumulation is the net accumulation of a substance by an 
organism as a result of uptake from all environmental sources.
    Bioaccumulation factor (BAF) is the ratio (in L/kg) of a substance's 
concentration in tissue of an aquatic organism to its concentration in 
the ambient water, in situations where both the organism and its food 
are exposed and the ratio does not change substantially over time.
    Bioaccumulative chemical of concern (BCC) is any chemical that has

implementation.
    (c) The Regional Administrator may extend the deadline for the 
submission required in paragraph (a) of this section if the Regional 
Administrator believes that the submission will be consistent with the 
requirements of this part and can be reviewed and approved pursuant to 
this section no later than March 23, 1997, or, for procedure 3.C of 
appendix F of this part, no later than November 13, 2002.
    (d) If a Great Lakes State or Tribe makes no submission pursuant to 
this part to EPA for review, the requirements of this part shall apply 
to discharges to waters of the Great Lakes System located within the 
State or Federal Indian reservation upon EPA's publication of a final 
rule indicating the effective date of the part 132 requirements in the 
identified jurisdictions.
    (e) If a Great Lakes State or Tribe submits criteria, methodologies, 
policies, and procedures pursuant to this part to EPA for review that 
contain substantial modifications of the State or Tribal NPDES program, 
EPA shall issue public notice and provide a minimum of 30 days for 
public comment on such modifications. The public notice shall conform 
with the requirements of 40 CFR 123.62.
    (f) After review of State or Tribal submissions under this section, 
and following the public comment period in subparagraph (e) of this 
section, if any, EPA shall either:
    (1) Publish notice of approval of the submission in the Federal 
Register within 90 days of such submission; or
    (2) Notify the State or Tribe within 90 days of such submission that 
EPA has determined that all or part of the submission is inconsistent 
with the requirements of the Clean Water Act or this part and identify 
any necessary changes to obtain EPA approval. If the State or Tribe 
fails to adopt such changes within 90 days after the notification, EPA 
shall publish a notice in the Federal Register identifying the approved 
and disapproved elements of

[[Page 623]]

the submission and a final rule in the Federal Register identifying the 
provisions of part 132 that shall apply to discharges within the State 
or Federal Indian reservation.
    (g) EPA's approval or disapproval of a State or Tribal submission 
shall be based on the requirements of this part and of the Clean Water 
Act. EPA's determination whether the criteria, methodologies, policies, 
and procedures in a State or Tribal submission are consistent with the 
requirements of this part will be based on whether:
    (1) For pollutants listed in Tables 1, 2, 3, and 4 of this part. The 
Great Lakes State or Tribe has adopted numeric water quality criteria as 
protective as each of the numeric criteria in Tables 1, 2, 3, and 4 of 
this part, taking into account any site-specific criteria modifications 
in accordance with procedure 1 of appendix F of this part;
    (2) For pollutants other than those listed in Tables 1, 2, 3, 4, and 
5 of this part. The Great Lakes State or Tribe demonstrates that either:
    (i) It has adopted numeric criteria in its water quality standards 
that were derived, or are as protective as or more protective than could 
be derived, using the methodologies in appendixes A, B, C, and D of this 
part, and the site-specific criteria modification procedures in 
accordance with procedure 1 of appendix F of this part; or
    (ii) It has adopted a procedure by which water quality-based 
effluent limits and total maximum daily loads are developed using the 
more protective of:
    (A) Numeric criteria adopted by the State into State water quality 
standards and approved by EPA prior to March 23, 1997; or
    (B) Water quality criteria and values derived pursuant to Sec. 
132.4(c); and
    (3) For methodologies, policies, and procedures. The Great Lakes 
State or Tribe has adopted methodologies, policies, and procedures as 
protective as the corresponding methodology, policy, or procedure in 
Sec. 132.4. The Great Lakes State or Tribe may adopt provisions that 
are more protective than those contained in this part. Adoption of a 
more protective element in one provision may be used to offset a less 
protective element in the same provision as long as the adopted 
provision is as protective as the corresponding provision in this part; 
adoption of a more protective element in one provision, however, is not 
justification for adoption of a less protective element in another 
provision of this part.
    (h) A submission by a Great Lakes State or Tribe will need to 
include any provisions that EPA determines, based on EPA's authorities 
under the Clean Water Act and the results of consultation under section 
7 of the Endangered Species Act, are necessary to ensure that water 
quality is not likely to jeopardize the continued existence of any 
endangered or threatened species listed under section 4 of the 
Endangered Species Act or result in the destruction or adverse 
modification of such species' critical habitat.
    (i) EPA's approval of the elements of a State's or Tribe's 
submission will constitute approval under section 118 of the Clean Water 
Act, approval of the submitted water quality standards pursuant to 
section 303 of the Clean Water Act, and approval of the submitted 
modifications to the State's or Tribe's NPDES program pursuant to 
section 402 of the Clean Water Act.

   Sec. Appendix A to Part 132--Great Lakes Water Quality Initiative 
    Methodologies for Development of Aquatic Life Criteria and Values

         Methodology for Deriving Aquatic Life Criteria: Tier I

    Great Lakes States and Tribes shall adopt provisions consistent with 
(as protective as) this appendix.

[[Page 627]]

                             I. Definitions

    A. Material of Concern. When defining the material of concern the 
following should be considered:
    1. Each separate chemical that does not ionize substantially in most 
natural bodies of water should usually be considered a separate 
material, except possibly for structurally similar organic compounds 
that only exist in large quantities as commercial mixtures of the 
various compounds and apparently have similar biological, chemical, 
physical, and toxicological properties.
    2. For chemicals that ionize substantially in most natural bodies of 
water (e.g., some phenols and organic acids, some salts of phenols and 
organic acids, and most inorganic salts and coordination complexes of 
metals and metalloid), all forms that would be in chemical equilibrium 
should usually be considered one material. Each different oxidation 
state of a metal and each different non-ionizable covalently bonded 
organometallic compound should usually be considered a separate 
material.
    3. The definition of the material of concern should include an 
operational analytical component. Identification of a material simply as 
``sodium,'' for example, implies ``total sodium,'' but leaves room for 
doubt. If ``total'' is meant, it must be explicitly stated. Even 
``total'' has different operational definitions, some of which do not 
necessarily measure ``all that is there'' in all samples. Thus, it is 
also necessary to reference or describe the analytical method that is 
intended. The selection of the operational analytical component should 
take into account the analytical and environmental chemistry of the 
material and various practical considerations, such as labor and 
equipment requirements, and whether the method would require measurement 
in the field or would allow measurement after samples are transported to 
a laboratory.
    a. The primary requirements of the operational analytical component 
are that it be appropriate for use on samples of receiving water, that 
it be compatible with the available toxicity and bioaccumulation data 
without making extrapolations that are too hypothetical, and that it 
rarely result in underprotection or overprotection of aquatic organisms 
and their uses. Toxicity is the property of a material, or combination 
of materials, to adversely affect organisms.
    b. Because an ideal analytical measurement will rarely be available, 
an appropriate compromise measurement will usually have to be used. This 
compromise measurement must fit with the general approach that if an 
ambient concentration is lower than the criterion, unacceptable effects 
will probably not occur, i.e., the compromise measure must not err on 
the side of underprotection when measurements are made on a surface 
water. What is an appropriate measurement in one situation might not be 
appropriate for another. For example, because the chemical and physical 
properties of an effluent are usually quite different from those of the 
receiving water, an analytical method that is appropriate for analyzing 
an effluent might not be appropriate for expressing a criterion, and 
vice versa. A criterion should be based on an appropriate analytical 
measurement, but the criterion is not rendered useless if an ideal 
measurement either is not available or is not feasible.
    Note: The analytical chemistry of the material might have to be 
taken into account when defining the material or when judging the 
acceptability of some toxicity tests, but a criterion must not be based 
on the sensitivity of an analytical method. When aquatic organisms are 
more sensitive than routine analytical methods, the proper solution is 
to develop better analytical methods.
    4. It is now the policy of EPA that the use of dissolved metal to 
set and measure compliance with water quality standards is the 
recommended approach, because dissolved metal more closely approximates 
the bioavailable fraction of metal in the water column that does total 
recoverable metal. One reason is that a primary mechanism for water 
column toxicity is adsorption at the gill surface which requires metals 
to be in the dissolved form. Reasons for the consideration of total 
recoverable metals criteria include risk management considerations not 
covered by evaluation of water column toxicity. A risk manager may 
consider sediments and food chain effects and may decide to take a 
conservative approach for metals, considering that metals are very 
persistent chemicals. This approach could include the use of total 
recoverable metal in water quality standards. A range of different risk 
management decisions can be justified. EPA recommends that State water 
quality standards be based on dissolved metal. EPA will also approve a 
State risk management decision to adopt standards based on total 
recoverable metal, if those standards are otherwise approvable under 
this program.
    B. Acute Toxicity. Concurrent and delayed adverse effect(s) that 
results from an acute exposure and occurs within any short observation 
period which begins when the exposure begins, may extend beyond the 
exposure period, and usually does not constitute a substantial portion 
of the life span of the organism. (Concurrent toxicity is an adverse 
effect to an organism that results from, and occurs during, its exposure 
to one or more test materials.) Exposure constitutes contact with a 
chemical or physical agent. Acute exposure, however, is exposure of an 
organism for any short period which usually does not constitute a 
substantial portion of its life span.

[[Page 628]]

    C. Chronic Toxicity. Concurrent and delayed adverse effect(s) that 
occurs only as a result of a chronic exposure. Chronic exposure is 
exposure of an organism for any long period or for a substantial portion 
of its life span.

                         II. Collection of Data

    A. Collect all data available on the material concerning toxicity to 
aquatic animals and plants.
    B. All data that are used should be available in typed, dated, and 
signed hard copy (e.g., publication, manuscript, letter, memorandum, 
etc.) with enough supporting information to indicate that acceptable 
test procedures were used and that the results are reliable. In some 
cases, it might be appropriate to obtain written information from the 
investigator, if possible. Information that is not available for 
distribution shall not be used.
    C. Questionable data, whether published or unpublished, must not be 
used. For example, data must be rejected if they are from tests that did 
not contain a control treatment, tests in which too many organisms in 
the control treatment died or showed signs of stress or disease, and 
tests in which distilled or deionized water was used as the dilution 
water without the addition of appropriate salts.
    D. Data on technical grade materials may be used if appropriate, but 
data on formulated mixtures and emulsifiable concentrates of the 
material must not be used.
    E. For some highly volatile, hydrolyzable, or degradable materials, 
it might be appropriate to use only results of flow-through tests in 
which the concentrations of test material in test solutions were 
measured using acceptable analytical methods. A flow-through test is a 
test with aquatic organisms in which test solutions flow into constant-
volume test chambers either intermittently (e.g., every few minutes) or 
continuously, with the excess flowing out.
    F. Data must be rejected if obtained using:
    1. Brine shrimp, because they usually only occur naturally in water 
with salinity greater than 35 g/kg.
    2. Species that do not have reproducing wild populations in North 
America.
    3. Organisms that were previously exposed to substantial 
concentrations of the test material or other contaminants.
    4. Saltwater species except for use in deriving acute-chronic 
ratios. An ACR is a standard measure of the acute toxicity of a material 
divided by an appropriate measure of the chronic toxicity of the same 
material under comparable conditions.
    G. Questionable data, data on formulated mixtures and emulsifiable 
concentrates, and data obtained with species non-resident to North 
America or previously exposed organisms may be used to provide auxiliary 
information but must not be used in the derivation of criteria.

                           III. Required Data

    A. Certain data should be available to help ensure that each of the 
major kinds of possible adverse effects receives adequate consideration. 
An adverse effect is a change in an organism that is harmful to the 
organism. Exposure means contact with a chemical or physical agent. 
Results of acute and chronic toxicity tests with representative species 
of aquatic animals are necessary so that data available for tested 
species can be considered a useful indication of the sensitivities of 
appropriate untested species. Fewer data concerning toxicity to aquatic 
plants are usually available because procedures for conducting tests 
with plants and interpreting the results of such tests are not as well 
developed.
    B. To derive a Great Lakes Tier I criterion for aquatic organisms 
and their uses, the following must be available:
    1. Results of acceptable acute (or chronic) tests (see section IV or 
VI of this appendix) with at least one species of freshwater animal in 
at least eight different families such that all of the following are 
included:
    a. The family Salmonidae in the class Osteichthyes;
    b. One other family (preferably a commercially or recreationally 
important, warmwater species) in the class Osteichthyes (e.g., bluegill, 
channel catfish);
    c. A third family in the phylum Chordata (e.g., fish, amphibian);
    d. A planktonic crustacean (e.g., a cladoceran, copepod);
    e. A benthic crustacean (e.g., ostracod, isopod, amphipod, 
crayfish);
    f. An insect (e.g., mayfly, dragonfly, damselfly, stonefly, 
caddisfly, mosquito, midge);
    g. A family in a phylum other than Arthropoda or Chordata (e.g., 
Rotifera, Annelida, Mollusca);
    h. A family in any order of insect or any phylum not already 
represented.
    2. Acute-chronic ratios (see section VI of this appendix) with at 
least one species of aquatic animal in at least three different families 
provided that of the three species:
    a. At least one is a fish;
    b. At least one is an invertebrate; and
    c. At least one species is an acutely sensitive freshwater species 
(the other two may be saltwater species).
    3. Results of at least one acceptable test with a freshwater algae 
or vascular plant is desirable but not required for criterion derivation 
(see section VIII of this appendix). If plants are among the aquatic 
organisms most sensitive to the material, results of a test with a plant 
in another phylum (division) should also be available.

[[Page 629]]

    C. If all required data are available, a numerical criterion can 
usually be derived except in special cases. For example, derivation of a 
chronic criterion might not be possible if the available ACRs vary by 
more than a factor of ten with no apparent pattern. Also, if a criterion 
is to be related to a water quality characteristic (see sections V and 
VII of this appendix), more data will be required.
    D. Confidence in a criterion usually increases as the amount of 
available pertinent information increases. Thus, additional data are 
usually desirable.

                          IV. Final Acute Value

    A. Appropriate measures of the acute (short-term) toxicity of the 
material to a variety of species of aquatic animals are used to 
calculate the Final Acute Value (FAV). The calculated Final Acute Value 
is a calculated estimate of the concentration of a test material such 
that 95 percent of the genera (with which acceptable acute toxicity 
tests have been conducted on the material) have higher Genus Mean Acute 
Values (GMAVs). An acute test is a comparative study in which organisms, 
that are subjected to different treatments, are observed for a short 
period usually not constituting a substantial portion of their life 
span. However, in some cases, the Species Mean Acute Value (SMAV) of a 
commercially or recreationally important species of the Great Lakes 
System is lower than the calculated FAV, then the SMAV replaces the 
calculated FAV in order to provide protection for that important 
species.
    B. Acute toxicity tests shall be conducted using acceptable 
procedures. For good examples of acceptable procedures see American 
Society for Testing and Materials (ASTM) Standard E 729, Guide for 
Conducting Acute Toxicity Tests with Fishes, Macroinvertebrates, and 
Amphibians.
    C. Except for results with saltwater annelids and mysids, results of 
acute tests during which the test organisms were fed should not be used, 
unless data indicate that the food did not affect the toxicity of the 
test material. (Note: If the minimum acute-chronic ratio data 
requirements (as described in section III.B.2 of this appendix) are not 
met with freshwater data alone, saltwater data may be used.)
    D. Results of acute tests conducted in unusual dilution water, e.g., 
dilution water in which total organic carbon or particulate matter 
exceeded five mg/L, should not be used, unless a relationship is 
developed between acute toxicity and organic carbon or particulate 
matter, or unless data show that organic carbon or particulate matter, 
etc., do not affect toxicity.
    E. Acute values must be based upon endpoints which reflect the total 
severe adverse impact of the test material on the organisms used in the 
test. Therefore, only the following kinds of data on acute toxicity to 
aquatic animals shall be used:
    1. Tests with daphnids and other cladocerans must be started with 
organisms less than 24 hours old and tests with midges must be started 
with second or third instar larvae. It is preferred that the results 
should be the 48-hour EC50 based on the total percentage of organisms 
killed and immobilized. If such an EC50 is not available for a test, the 
48-hour LC50 should be used in place of the desired 48-hour EC50. An 
EC50 or LC50 of longer than 48 hours can be used as long as the animals 
were not fed and the control animals were acceptable at the end of the 
test. An EC50 is a statistically or graphically estimated concentration 
that is expected to cause one or more specified effects in 50% of a 
group of organisms under specified conditions. An LC50 is a 
statistically or graphically estimated concentration that is expected to 
be lethal to 50% of a group of organisms under specified conditions.
    2. It is preferred that the results of a test with embryos and 
larvae of barnacles, bivalve molluscs (clams, mussels, oysters and 
scallops), sea urchins, lobsters, crabs, shrimp and abalones be the 96-
hour EC50 based on the percentage of organisms with incompletely 
developed shells plus the percentage of organisms killed. If such an 
EC50 is not available from a test, of the values that are available from 
the test, the lowest of the following should be used in place of the 
desired 96-hour EC50: 48- to 96-hour EC50s based on percentage of 
organisms with incompletely developed shells plus percentage of 
organisms killed, 48- to 96-hour EC50s based upon percentage of 
organisms with incompletely developed shells, and 48-hour to 96-hour 
LC50s. (Note: If the minimum acute-chronic ratio data requirements (as 
described in section III.B.2 of this appendix) are not met with 
freshwater data alone, saltwater data may be used.)
    3. It is preferred that the result of tests with all other aquatic 
animal species and older life stages of barnacles, bivalve molluscs 
(clams, mussels, oysters and scallops), sea urchins, lobsters, crabs, 
shrimp and abalones be the 96-hour EC50 based on percentage of organisms 
exhibiting loss of equilibrium plus percentage of organisms immobilized 
plus percentage of organisms killed. If such an EC50 is not available 
from a test, of the values that are available from a test the lower of 
the following should be used in place of the desired 96-hour EC50: the 
96-hour EC50 based on percentage of organisms exhibiting loss of 
equilibrium plus percentage of organisms immobilized and the 96-hour 
LC50.
    4. Tests whose results take into account the number of young 
produced, such as most tests with protozoans, are not considered

[[Page 630]]

acute tests, even if the duration was 96 hours or less.
    5. If the tests were conducted properly, acute values reported as 
``greater than'' values and those which are above the solubility of the 
test material should be used, because rejection of such acute values 
would bias the Final Acute Value by eliminating acute values for 
resistant species.
    F. If the acute toxicity of the material to aquatic animals has been 
shown to be related to a water quality characteristic such as hardness 
or particulate matter for freshwater animals, refer to section V of this 
appendix.
    G. The agreement of the data within and between species must be 
considered. Acute values that appear to be questionable in comparison 
with other acute and chronic data for the same species and for other 
species in the same genus must not be used. For example, if the acute 
values available for a species or genus differ by more than a factor of 
10, rejection of some or all of the values would be appropriate, absent 
countervailing circumstances.
    H. If the available data indicate that one or more life stages are 
at least a factor of two more resistant than one or more other life 
stages of the same species, the data for the more resistant life stages 
must not be used in the calculation of the SMAV because a species cannot 
be considered protected from acute toxicity if all of the life stages 
are not protected.
    I. For each species for which at least one acute value is available, 
the SMAV shall be calculated as the geometric mean of the results of all 
acceptable flow-through acute toxicity tests in which the concentrations 
of test material were measured with the most sensitive tested life stage 
of the species. For a species for which no such result is available, the 
SMAV shall be calculated as the geometric mean of all acceptable acute 
toxicity tests with the most sensitive tested life stage, i.e., results 
of flow-through tests in which the concentrations were not measured and 
results of static and renewal tests based on initial concentrations 
(nominal concentrations are acceptable for most test materials if 
measured concentrations are not available) of test material. A renewal 
test is a test with aquatic organisms in which either the test solution 
in a test chamber is removed and replaced at least once during the test 
or the test organisms are transferred into a new test solution of the 
same composition at least once during the test. A static test is a test 
with aquatic organisms in which the solution and organisms that are in a 
test chamber at the beginning of the test remain in the chamber until 
the end of the test, except for removal of dead test organisms.

    Note 1: Data reported by original investigators must not be rounded 
off. Results of all intermediate calculations must not be rounded off to 
fewer than four significant digits.
    Note 2: The geometric mean of N numbers is the Nth root of the 
product of the N numbers. Alternatively, the geometric mean can be 
calculated by adding the logarithms of the N numbers, dividing the sum 
by N, and taking the antilog of the quotient. The geometric mean of two 
numbers is the square root of the product of the two numbers, and the 
geometric mean of one number is that number. Either natural (base e) or 
common (base 10) logarithms can be used to calculate geometric means as 
long as they are used consistently within each set of data, i.e., the 
antilog used must match the logarithms used.
    Note 3: Geometric means, rather than arithmetic means, are used here 
because the distributions of sensitivities of individual organisms in 
toxicity tests on most materials and the distributions of sensitivities 
of species within a genus are more likely to be lognormal than normal. 
Similarly, geometric means are used for ACRs because quotients are 
likely to be closer to lognormal than normal distributions. In addition, 
division of the geometric mean of a set of numerators by the geometric 
mean of the set of denominators will result in the geometric mean of the 
set of corresponding quotients.

    J. For each genus for which one or more SMAVs are available, the 
GMAV shall be calculated as the geometric mean of the SMAVs available 
for the genus.
    K. Order the GMAVs from high to low.
    L. Assign ranks, R, to the GMAVs from ``1'' for the lowest to ``N'' 
for the highest. If two or more GMAVs are identical, assign them 
successive ranks.
    M. Calculate the cumulative probability, P, for each GMAV as R/(N + 
1).
    N. Select the four GMAVs which have cumulative probabilities closest 
to 0.05 (if there are fewer than 59 GMAVs, these will always be the four 
lowest GMAVs).
    O. Using the four selected GMAVs, and Ps, calculate

[[Page 631]]

    Note: Natural logarithms (logarithms to base e, denoted as ln) are 
used herein merely because they are easier to use on some hand 
calculators and computers than common (base 10) logarithms. Consistent 
use of either will produce the same result.
    P. If for a commercially or recreationally important species of the 
Great Lakes System the geometric mean of the acute values from flow-
through tests in which the concentrations of test material were measured 
is lower than the calculated Final Acute Value (FAV), then that 
geometric mean must be used as the FAV instead of the calculated FAV.
    Q. See section VI of this appendix.

                         V. Final Acute Equation

    A. When enough data are available to show that acute toxicity to two 
or more species is similarly related to a water quality characteristic, 
the relationship shall be taken into account as described in sections 
V.B through V.G of this appendix or using analysis of covariance. The 
two methods are equivalent and produce identical results. The manual 
method described below provides an understanding of this application of 
covariance analysis, but computerized versions of covariance analysis 
are much more convenient for analyzing large data sets. If two or more 
factors affect toxicity, multiple regression analysis shall be used.
    B. For each species for which comparable acute toxicity values are 
available at two or more different values of the water quality 
characteristic, perform a least squares regression of the acute toxicity 
values on the corresponding values of the water quality characteristic 
to obtain the slope and its 95 percent confidence limits for each 
species.
    Note: Because the best documented relationship is that between 
hardness and acute toxicity of metals in fresh water and a log-log 
relationship fits these data, geometric means and natural logarithms of 
both toxicity and water quality are used in the rest of this section. 
For relationships based on other water quality characteristics, such as 
Ph, temperature, no transformation or a different transformation might 
fit the data better, and appropriate changes will be necessary 
throughout this section.
    C. Decide whether the data for each species are relevant, taking 
into account the range and number of the tested values of the water 
quality characteristic and the degree of agreement within and between 
species. For example, a slope based on six data points might be of 
limited value if it is based only on data for a very narrow range of 
values of the water quality characteristic. A slope based on only two 
data points, however, might be useful if it is consistent with other 
information and if the two points cover a broad enough range of the 
water quality characteristic. In addition, acute values that appear to 
be questionable in comparison with other acute and chronic data 
available for the same species and for other species in the same genus 
should not be used. For example, if after adjustment for the water 
quality characteristic, the acute values available for a species or 
genus differ by more than a factor of 10, rejection of some or all of 
the values would be appropriate, absent countervailing justification. If 
useful slopes are not available for at least one fish and one 
invertebrate or if the available slopes are too dissimilar or if too few 
data are available to adequately define the relationship between acute 
toxicity and the

[[Page 632]]

water quality characteristic, return to section IV.G of this appendix, 
using the results of tests conducted under conditions and in waters 
similar to those commonly used for toxicity tests with the species.
    D. For each species, calculate the geometric mean of the available 
acute values and then divide each of the acute values for the species by 
the geometric mean for the species. This normalizes the acute values so 
that the geometric mean of the normalized values for each species 
individually and for any combination of species is 1.0.
    E. Similarly normalize the values of the water quality 
characteristic for each species individually using the same procedure as 
above.
    F. Individually for each species perform a least squares regression 
of the normalized acute values of the water quality characteristic. The 
resulting slopes and 95 percent confidence limits will be identical to 
those obtained in section V.B. of this appendix. If, however, the data 
are actually plotted, the line of best fit for each individual species 
will go through the point 1,1 in the center of the graph.
    G. Treat all of the normalized data as if they were all for the same 
species and perform a least squares regression of all of the normalized 
acute values on the corresponding normalized values of the water quality 
characteristic to obtain the pooled acute slope, V, and its 95 percent 
confidence limits. If all of the normalized data are actually plotted, 
the line of best fit will go through the point 1,1 in the center of the 
graph.
    H. For each species calculate the geometric mean, W, of the acute 
toxicity values and the geometric mean, X, of the values of the water 
quality characteristic. (These were calculated in sections V.D and V.E 
of this appendix).
    I. For each species, calculate the logarithm, Y, of the SMAV at a 
selected value, Z, of the water quality characteristic using the 
equation:

Y = ln W-V(ln X-ln Z)

    J. For each species calculate the SMAV at X using the equation:

SMAV = e\Y\
    Note: Alternatively, the SMAVs at Z can be obtained by skipping step 
H above, using the equations in steps I and J to adjust each acute value 
individually to Z, and then calculating the geometric mean of the 
adjusted values for each species individually. This alternative 
procedure allows an examination of the range of the adjusted acute 
values for each species.
    K. Obtain the FAV at Z by using the procedure described in sections 
IV.J through IV.O of this appendix.
    L. If, for a commercially or recreationally important species of the 
Great Lakes System the geometric mean of the acute values at Z from 
flow-through tests in which the concentrations of the test material were 
measured is lower than the FAV at Z, then the geometric mean must be 
used as the FAV instead of the FAV.
    M. The Final Acute Equation is written as:

FAV = e(V[ln(waterqualitycharacteristic)] = A - V[lnZ]),

where:
V = pooled acute slope, and A = ln(FAV at Z).

    Because V, A, and Z are known, the FAV can be calculated for any 
selected value of the water quality characteristic.

                         VI. Final Chronic Value

    A. Depending on the data that are available concerning chronic 
toxicity to aquatic animals, the Final Chronic Value (FCV) can be 
calculated in the same manner as the FAV or by dividing the FAV by the 
Final Acute-Chronic Ratio (FACR). In some cases, it might not be 
possible to calculate a FCV. The FCV is (a) a calculated estimate of the 
concentration of a test material such that 95 percent of the genera 
(with which acceptable chronic toxicity tests have been conducted on the 
material) have higher GMCVs, or (b) the quotient of an FAV divided by an 
appropriate ACR, or (c) the SMCV of an important and/or critical 
species, if the SMCV is lower than the calculated estimate or the 
quotient, whichever is applicable.
    Note: As the name implies, the ACR is a way of relating acute and 
chronic toxicities.
    B. Chronic values shall be based on results of flow-through (except 
renewal is acceptable for daphnids) chronic tests in which the 
concentrations of test material in the test solutions were properly 
measured at appropriate times during the test. A chronic test is a 
comparative study in which organisms, that are subjected to different 
treatments, are observed for a long period or a substantial portion of 
their life span.
    C. Results of chronic tests in which survival, growth, or 
reproduction in the control treatment was unacceptably low shall not be 
used. The limits of acceptability will depend on the species.
    D. Results of chronic tests conducted in unusual dilution water, 
e.g., dilution water in which total organic carbon or particulate matter 
exceeded five mg/L, should not be used, unless a relationship is 
developed between chronic toxicity and organic carbon or particulate 
matter, or unless data show that organic carbon, particulate matter, 
etc., do not affect toxicity.
    E. Chronic values must be based on endpoints and lengths of exposure 
appropriate to the species. Therefore, only results of the following 
kinds of chronic toxicity tests shall be used:

[[Page 633]]

    1. Life-cycle toxicity tests consisting of exposures of each of two 
or more groups of individuals of a species to a different concentration 
of the test material throughout a life cycle. To ensure that all life 
stages and life processes are exposed, tests with fish should begin with 
embryos or newly hatched young less than 48 hours old, continue through 
maturation and reproduction, and should end not less than 24 days (90 
days for salmonids) after the hatching of the next generation. Tests 
with daphnids should begin with young less than 24 hours old and last 
for not less than 21 days, and for ceriodaphnids not less than seven 
days. For good examples of acceptable procedures see American Society 
for Testing and Materials (ASTM) Standard E 1193 Guide for conducting 
renewal life-cycle toxicity tests with Daphnia magna and ASTM Standard E 
1295 Guide for conducting three-brood, renewal toxicity tests with 
Ceriodaphnia dubia. Tests with mysids should begin with young less than 
24 hours old and continue until seven days past the median time of first 
brood release in the controls. For fish, data should be obtained and 
analyzed on survival and growth of adults and young, maturation of males 
and females, eggs spawned per female, embryo viability (salmonids only), 
and hatchability. For daphnids, data should be obtained and analyzed on 
survival and young per female. For mysids, data should be obtained and 
analyzed on survival, growth, and young per female.
    2. Partial life-cycle toxicity tests consist of exposures of each of 
two more groups of individuals of a species of fish to a different 
concentration of the test material through most portions of a life 
cycle. Partial life-cycle tests are allowed with fish species that 
require more than a year to reach sexual maturity, so that all major 
life stages can be exposed to the test material in less than 15 months. 
A life-cycle test is a comparative study in which organisms, that are 
subjected to different treatments, are observed at least from a life 
stage in one generation to the same life-stage in the next generation. 
Exposure to the test material should begin with immature juveniles at 
least two months prior to active gonad development, continue through 
maturation and reproduction, and end not less than 24 days (90 days for 
salmonids) after the hatching of the next generation. Data should be 
obtained and analyzed on survival and growth of adults and young, 
maturation of males and females, eggs spawned per female, embryo 
viability (salmonids only), and hatchability.
    3. Early life-stage toxicity tests consisting of 28- to 32-day (60 
days post hatch for salmonids) exposures of the early life stages of a 
species of fish from shortly after fertilization through embryonic, 
larval, and early juvenile development. Data should be obtained and 
analyzed on survival and growth.
    Note: Results of an early life-stage test are used as predictions of 
results of life-cycle and partial life-cycle tests with the same 
species. Therefore, when results of a life-cycle or partial life-cycle 
test are available, results of an early life-stage test with the same 
species should not be used. Also, results of early life-stage tests in 
which the incidence of mortalities or abnormalities increased 
substantially near the end of the test shall not be used because the 
results of such tests are possibly not good predictions of comparable 
life-cycle or partial life-cycle tests.
    F. A chronic value may be obtained by calculating the geometric mean 
of the lower and upper chronic limits from a chronic test or by 
analyzing chronic data using regression analysis.
    1. A lower chronic limit is the highest tested concentration:
    a. In an acceptable chronic test;
    b. Which did not cause an unacceptable amount of adverse effect on 
any of the specified biological measurements; and
    c. Below which no tested concentration caused an unacceptable 
effect.
    2. An upper chronic limit is the lowest tested concentration:
    a. In an acceptable chronic test;
    b. Which did cause an unacceptable amount of adverse effect on one 
or more of the specified biological measurements; and,
    c. Above which all tested concentrations also caused such an effect.
    Note: Because various authors have used a variety of terms and 
definitions to interpret and report results of chronic tests, reported 
results should be reviewed carefully. The amount of effect that is 
considered unacceptable is often based on a statistical hypothesis test, 
but might also be defined in terms of a specified percent reduction from 
the controls. A small percent reduction (e.g., three percent) might be 
considered acceptable even if it is statistically significantly 
different from the control, whereas a large percent reduction (e.g., 30 
percent) might be considered unacceptable even if it is not 
statistically significant.
    G. If the chronic toxicity of the material to aquatic animals has 
been shown to be related to a water quality characteristic such as 
hardness or particulate matter for freshwater animals, refer to section 
VII of this appendix.
    H. If chronic values are available for species in eight families as 
described in section III.B.1 of this appendix, a SMCV shall be 
calculated for each species for which at least one chronic value is 
available by calculating the geometric mean of the results of all 
acceptable life-cycle and partial life-cycle toxicity tests with the 
species; for a species of fish for which no such result is available, 
the

[[Page 634]]

SMCV is the geometric mean of all acceptable early life-stage tests. 
Appropriate GMCVs shall also be calculated. A GMCV is the geometric mean 
of the SMCVs for the genus. The FCV shall be obtained using the 
procedure described in sections IV.J through IV.O of this appendix, 
substituting SMCV and GMCV for SMAV and GMAV respectively. See section 
VI.M of this appendix.
    Note: Section VI.I through VI.L are for use when chronic values are 
not available for species in eight taxonomic families as described in 
section III.B.1 of this appendix.
    I. For each chronic value for which at least one corresponding 
appropriate acute value is available, calculate an ACR, using for the 
numerator the geometric mean of the results of all acceptable flow-
through (except static is acceptable for daphnids and midges) acute 
tests in the same dilution water in which the concentrations are 
measured. For fish, the acute test(s) should be conducted with 
juveniles. The acute test(s) should be part of the same study as the 
chronic test. If acute tests were not conducted as part of the same 
study, but were conducted as part of a different study in the same 
laboratory and dilution water, then they may be used. If no such acute 
tests are available, results of acute tests conducted in the same 
dilution water in a different laboratory may be used. If no such acute 
tests are available, an ACR shall not be calculated.
    J. For each species, calculate the SMACR as the geometric mean of 
all ACRs available for that species. If the minimum ACR data 
requirements (as described in section III.B.2 of this appendix) are not 
met with freshwater data alone, saltwater data may be used along with 
the freshwater data.
    K. For some materials, the ACR seems to be the same for all species, 
but for other materials the ratio seems to increase or decrease as the 
SMAV increases. Thus the FACR can be obtained in three ways, depending 
on the data available:
    1. If the species mean ACR seems to increase or decrease as the 
SMAVs increase, the FACR shall be calculated as the geometric mean of 
the ACRs for species whose SMAVs are close to the FAV.
    2. If no major trend is apparent and the ACRs for all species are 
within a factor of ten, the FACR shall be calculated as the geometric 
mean of all of the SMACRs.
    3. If the most appropriate SMACRs are less than 2.0, and especially 
if they are less than 1.0, acclimation has probably occurred during the 
chronic test. In this situation, because continuous exposure and 
acclimation cannot be assured to provide adequate protection in field 
situations, the FACR should be assumed to be two, so that the FCV is 
equal to the Criterion Maximum Concentration (CMC). (See section X.B of 
this appendix.)
    If the available SMACRs do not fit one of these cases, a FACR may 
not be obtained and a Tier I FCV probably cannot be calculated.
    L. Calculate the FCV by dividing the FAV by the FACR.
    FCV = FAV / FACR
If there is a Final Acute Equation rather than a FAV, see also section V 
of this appendix.
    M. If the SMCV of a commercially or recreationally important species 
of the Great Lakes System is lower than the calculated FCV, then that 
SMCV must be used as the FCV instead of the calculated FCV.
    N. See section VIII of this appendix.

                       VII. Final Chronic Equation

    A. A Final Chronic Equation can be derived in two ways. The 
procedure described in section VII.A of this appendix will result in the 
chronic slope being the same as the acute slope. The procedure described 
in sections VII.B through N of this appendix will usually result in the 
chronic slope being different from the acute slope.
    1. If ACRs are available for enough species at enough values of the 
water quality characteristic to indicate that the ACR appears to be the 
same for all species and appears to be independent of the water quality 
characteristic, calculate the FACR as the geometric mean of the 
available SMACRs.
    2. Calculate the FCV at the selected value Z of the water quality 
characteristic by dividing the FAV at Z (see section V.M of this 
appendix) by the FACR.
    3. Use V = pooled acute slope (see section V.M of this appendix), 
and
    L = pooled chronic slope.
    4. See section VII.M of this appendix.
    B. When enough data are available to show that chronic toxicity to 
at least one species is related to a water quality characteristic, the 
relationship should be taken into account as described in sections C 
through G below or using analysis of covariance. The two methods are 
equivalent and produce identical results. The manual method described 
below provides an understanding of this application of covariance 
analysis, but computerized versions of covariance analysis are much more 
convenient for analyzing large data sets. If two or more factors affect 
toxicity, multiple regression analysis shall be used.
    C. For each species for which comparable chronic toxicity values are 
available at two or more different values of the water quality 
characteristic, perform a least squares regression of the chronic 
toxicity values on the corresponding values of the water quality 
characteristic to obtain the slope and its 95 percent confidence limits 
for each species.
    Note: Because the best documented relationship is that between 
hardness and acute toxicity of metals in fresh water and a log-

[[Page 635]]

log relationship fits these data, geometric means and natural logarithms 
of both toxicity and water quality are used in the rest of this section. 
For relationships based on other water quality characteristics, such as 
Ph, temperature, no transformation or a different transformation might 
fit the data better, and appropriate changes will be necessary 
throughout this section. It is probably preferable, but not necessary, 
to use the same transformation that was used with the acute values in 
section V of this appendix.
    D. Decide whether the data for each species are relevant, taking 
into account the range and number of the tested values of the water 
quality characteristic and the degree of agreement within and between 
species. For example, a slope based on six data points might be of 
limited value if it is based only on data for a very narrow range of 
values of the water quality characteristic. A slope based on only two 
data points, however, might be more useful if it is consistent with 
other information and if the two points cover a broad range of the water 
quality characteristic. In addition, chronic values that appear to be 
questionable in comparison with other acute and chronic data available 
for the same species and for other species in the same genus in most 
cases should not be used. For example, if after adjustment for the water 
quality characteristic, the chronic values available for a species or 
genus differ by more than a factor of 10, rejection of some or all of 
the values is, in most cases, absent countervailing circumstances, 
appropriate. If a useful chronic slope is not available for at least one 
species or if the available slopes are too dissimilar or if too few data 
are available to adequately define the relationship between chronic 
toxicity and the water quality characteristic, it might be appropriate 
to assume that the chronic slope is the same as the acute slope, which 
is equivalent to assuming that the ACR is independent of the water 
quality characteristic. Alternatively, return to section VI.H of this 
appendix, using the results of tests conducted under conditions and in 
waters similar to those commonly used for toxicity tests with the 
species.
    E. Individually for each species, calculate the geometric mean of 
the available chronic values and then divide each chronic value for a 
species by the mean for the species. This normalizes the chronic values 
so that the geometric mean of the normalized values for each species 
individually, and for any combination of species, is 1.0.
    F. Similarly, normalize the values of the water quality 
characteristic for each species individually.
    G. Individually for each species, perform a least squares regression 
of the normalized chronic toxicity values on the corresponding 
normalized values of the water quality characteristic. The resulting 
slopes and the 95 percent confidence limits will be identical to those 
obtained in section VII.B of this appendix. Now, however, if the data 
are actually plotted, the line of best fit for each individual species 
will go through the point 1,1 in the center of the graph.
    H. Treat all of the normalized data as if they were all the same 
species and perform a least squares regression of all of the normalized 
chronic values on the corresponding normalized values of the water 
quality characteristic to obtain the pooled chronic slope, L, and its 95 
percent confidence limits.
    If all normalized data are actually plotted, the line of best fit 
will go through the point 1,1 in the center of the graph.
    I. For each species, calculate the geometric mean, M, of the 
toxicity values and the geometric mean, P, of the values of the water 
quality characteristic. (These are calculated in sections VII.E and F of 
this appendix.)
    J. For each species, calculate the logarithm, Q, of the SMCV at a 
selected value, Z, of the water quality characteristic using the 
equation:

Q = ln M--L(ln P-ln Z)
    Note: Although it is not necessary, it is recommended that the same 
value of the water quality characteristic be used here as was used in 
section V of this appendix.
    K. For each species, calculate a SMCV at Z using the equation:

SMCV = e\Q\
    Note: Alternatively, the SMCV at Z can be obtained by skipping 
section VII.J of this appendix, using the equations in sections VII.J 
and K of this appendix to adjust each chronic value individually to Z, 
and then calculating the geometric means of the adjusted values for each 
species individually. This alternative procedure allows an examination 
of the range of the adjusted chronic values for each species.
    L. Obtain the FCV at Z by using the procedure described in sections 
IV.J through O of this appendix.
    M. If the SMCV at Z of a commercially or recreationally important 
species of the Great Lakes System is lower than the calculated FCV at Z, 
then that SMCV shall be used as the FCV at Z instead of the calculated 
FCV.
    N. The Final Chronic Equation is written as:

FCV = e(L&[ln(waterqualitycharacteristic)] = lnS-L[lnZ])

Where:

L = pooled chronic slope and S = FCV at Z.

    Because L, S, and Z are known, the FCV can be calculated for any 
selected value of the water quality characteristic.

[[Page 636]]

                         VIII. Final Plant Value

    A. A Final Plant Value (FPV) is the lowest plant value that was 
obtained with an important aquatic plant species in an acceptable 
toxicity test for which the concentrations of the test material were 
measured and the adverse effect was biologically important. Appropriate 
measures of the toxicity of the material to aquatic plants are used to 
compare the relative sensitivities of aquatic plants and animals. 
Although procedures for conducting and interpreting the results of 
toxicity tests with plants are not well-developed, results of tests with 
plants usually indicate that criteria which adequately protect aquatic 
animals and their uses will, in most cases, also protect aquatic plants 
and their uses.
    B. A plant value is the result of a 96-hour test conducted with an 
alga or a chronic test conducted with an aquatic vascular plant.
    Note: A test of the toxicity of a metal to a plant shall not be used 
if the medium contained an excessive amount of a complexing agent, such 
as EDTA, that might affect the toxicity of the metal. Concentrations of 
EDTA above 200 [micro] g/L should be considered excessive.
    C. The FPV shall be obtained by selecting the lowest result from a 
test with an important aquatic plant species in which the concentrations 
of test material are measured and the endpoint is biologically 
important.

                             IX. Other Data

    Pertinent information that could not be used in earlier sections 
might be available concerning adverse effects on aquatic organisms. The 
most important of these are data on cumulative and delayed toxicity, 
reduction in survival, growth, or reproduction, or any other adverse 
effect that has been shown to be biologically important. Delayed 
toxicity is an adverse effect to an organism that results from, and 
occurs after the end of, its exposure to one or more test materials. 
Especially important are data for species for which no other data are 
available. Data from behavioral, biochemical, physiological, microcosm, 
and field studies might also be available. Data might be available from 
tests conducted in unusual dilution water (see sections IV.D and VI.D of 
this appendix), from chronic tests in which the concentrations were not 
measured (see section VI.B of this appendix), from tests with previously 
exposed organisms (see section II.F.3 of this appendix), and from tests 
on formulated mixtures or emulsifiable concentrates (see section II.D of 
this appendix). Such data might affect a criterion if the data were 
obtained with an important species, the test concentrations were 
measured, and the endpoint was biologically important.

                              X. Criterion

    A. A criterion consists of two concentrations: the CMC and the 
Criterion Continuous Concentration (CCC).
    B. The CMC is equal to one-half the FAV. The CMC is an estimate of 
the highest concentration of a material in the water column to which an 
aquatic community can be exposed briefly without resulting in an 
unacceptable effect.
    C. The CCC is equal to the lowest of the FCV or the FPV (if 
available) unless other data (see section IX of this appendix) show that 
a lower value should be used. The CCC is an estimate of the highest 
concentration of a material in the water column to which an aquatic 
community can be exposed indefinitely without resulting in an 
unacceptable effect. If toxicity is related to a water quality 
characteristic, the CCC is obtained from the Final Chronic Equation or 
FPV (if available) that results in the lowest concentrations in the 
usual range of the water quality characteristic, unless other data (see 
section IX) show that a lower value should be used.
    D. Round both the CMC and the CCC to two significant digits.
    E. The criterion is stated as:
    The procedures described in the Tier I methodology indicate that, 
except possibly where a commercially or recreationally important species 
is very sensitive, aquatic organisms should not be affected unacceptably 
if the four-day average concentration of (1) does not exceed (2) [micro] 
g/L more than once every three years on the average and if the one-hour 
average concentration does not exceed (3) [micro] g/L more than once 
every three years on the average.
Where:

(1) = insert name of material
(2) = insert the CCC
(3) = insert the CMC

    If the CMC averaging period of one hour or the CCC averaging period 
of four days is inappropriate for the pollutant, or if the once-in-
three-year allowable excursion frequency is inappropriate for the 
pollutant or for the sites to which a criterion is applied, then the 
State may specify alternative averaging periods or frequencies. The 
choice of an alternative averaging period or frequency shall be 
justified by a scientifically defensible analysis demonstrating that the 
alternative values will protect the aquatic life uses of the water. 
Appropriate laboratory data and/or well-designed field biological 
surveys shall be submitted to EPA as justification for differing 
averaging periods and/or frequencies of exceedance.

                            XI. Final Review

    A. The derivation of the criterion should be carefully reviewed by 
rechecking each

[[Page 637]]

step of the Guidance in this part. Items that should be especially 
checked are:
    1. If unpublished data are used, are they well documented?
    2. Are all required data available?
    3. Is the range of acute values for any species greater than a 
factor of 10?
    4. Is the range of SMAVs for any genus greater than a factor of 10?
    5. Is there more than a factor of 10 difference between the four 
lowest GMAVs?
    6. Are any of the lowest GMAVs questionable?
    7. Is the FAV reasonable in comparison with the SMAVs and GMAVs?
    8. For any commercially or recreationally important species of the 
Great Lakes System, is the geometric mean of the acute values from flow-
through tests in which the concentrations of test material were measured 
lower than the FAV?
    9. Are any of the chronic values used questionable?
    10. Are any chronic values available for acutely sensitive species?
    11. Is the range of acute-chronic ratios greater than a factor of 
10?
    12. Is the FCV reasonable in comparison with the available acute and 
chronic data?
    13. Is the measured or predicted chronic value for any commercially 
or recreationally important species of the Great Lakes System below the 
FCV?
    14. Are any of the other data important?
    15. Do any data look like they might be outliers?
    16. Are there any deviations from the Guidance in this part? Are 
they acceptable?
    B. On the basis of all available pertinent laboratory and field 
information, determine if the criterion is consistent with sound 
scientific evidence. If it is not, another criterion, either higher or 
lower, shall be derived consistent with the Guidance in this part.

          Methodology for Deriving Aquatic Life Values: Tier II

                       XII. Secondary Acute Value

    If all eight minimum data requirements for calculating an FAV using 
Tier I are not met, a Secondary Acute Value (SAV) for the waters of the 
Great Lakes System shall be calculated for a chemical as follows:
    To calculate a SAV, the lowest GMAV in the database is divided by 
the Secondary Acute Factor (SAF) (Table A-1 of this appendix) 
corresponding to the number of satisfied minimum data requirements 
listed in the Tier I methodology (section III.B.1 of this appendix). 
(Requirements for definitions, data collection and data review, 
contained in sections I, II, and IV shall be applied to calculation of a 
SAV.) If all eight minimum data requirements are satisfied, a Tier I 
criterion calculation may be possible. In order to calculate a SAV, the 
database must contain, at a minimum, a genus mean acute value (GMAV) for 
one of the following three genera in the family Daphnidae--Ceriodaphnia 
sp., Daphnia sp., or Simocephalus sp.
    If appropriate, the SAV shall be made a function of a water quality 
characteristic in a manner similar to that described in Tier I.

                   XIII. Secondary Acute-Chronic Ratio

    If three or more experimentally determined ACRs, meeting the data 
collection and review requirements of Section VI of this appendix, are 
available for the chemical, determine the FACR using the procedure 
described in Section VI. If fewer than three acceptable experimentally 
determined ACRs are available, use enough assumed ACRs of 18 so that the 
total number of ACRs equals three. Calculate the Secondary Acute-Chronic 
Ratio (SACR) as the geometric mean of the three ACRs. Thus, if no 
experimentally determined ACRs are available, the SACR is 18.

                      XIV. Secondary Chronic Value

    Calculate the Secondary Chronic Value (SCV) using one of the 
following:
[GRAPHIC] [TIFF OMITTED] TR23MR95.099

    If appropriate, the SCV will be made a function of a water quality 
characteristic in a manner similar to that described in Tier I.

          XV. Commercially or Recreationally Important Species

    If for a commercially or recreationally important species of the 
Great Lakes System the geometric mean of the acute values or chronic 
values from flow-through tests in which the concentrations of the test 
materials were measured is lower than the calculated SAV or SCV, then 
that geometric mean must be used as the SAV or SCV instead of the 
calculated SAV or SCV.

                           XVI. Tier II Value

    A. A Tier II value shall consist of two concentrations: the 
Secondary Maximum Concentration (SMC) and the Secondary Continuous 
Concentration (SCC).

[[Page 638]]

    B. The SMC is equal to one-half of the SAV.
    C. The SCC is equal to the lowest of the SCV or the Final Plant 
Value, if available, unless other data (see section IX of this appendix) 
show that a lower value should be used.
    If toxicity is related to a water quality characteristic, the SCC is 
obtained from the Secondary Chronic Equation or FPV, if available, that 
results in the lowest concentrations in the usual range of the water 
quality characteristic, unless other data (See section IX of this 
appendix) show that a lower value should be used.
    D. Round both the SMC and the SCC to two significant digits.
    E. The Tier II value is stated as:
    The procedures described in the Tier II methodology indicate that, 
except possibly where a locally important species is very sensitive, 
aquatic organisms should not be affected unacceptably if the four-day 
average concentration of (1) does not exceed (2) [micro] g/L more than 
once every three years on the average and if the one-hour average 
concentration does not exceed (3) [micro] g/L more than once every three 
years on the average.

Where:

(1) = insert name of material
(2) = insert the SCC
(3) = insert the SMC

    As discussed above, States and Tribes have the discretion to specify 
alternative averaging periods or frequencies (see section X.E. of this 
appendix).

                     XVII. Appropriate Modifications

    On the basis of all available pertinent laboratory and field 
information, determine if the Tier II value is consistent with sound 
scientific evidence. If it is not, another value, either higher or 
lower, shall be derived consistent with the Guidance in this part.

    Sec. Appendix B to Part 132--Great Lakes Water Quality Initiative

            Methodology for Deriving Bioaccumulation Factors

    Great Lakes States and Tribes shall adopt provisions consistent with 
(as protective as) this appendix.

                             I. Introduction

    A. The purpose of this methodology is to describe procedures for 
deriving bioaccumulation factors (BAFs) to be used in the calculation of 
Great Lakes Water Quality Guidance (Guidance) human health Tier I 
criteria and Tier II values and wildlife Tier I criteria. A subset of 
the human health BAFs are also used to identify the chemicals that are 
considered bioaccumulative chemicals of concern (BCCs).
    B. Bioaccumulation reflects uptake of a substance by aquatic 
organisms exposed to the substance through all routes (i.e., ambient 
water and food), as would occur in nature. Bioconcentration reflects 
uptake of a substance by aquatic organisms exposed to the substance only 
through the ambient water. Both BAFs and bioconcentration factors (BCFs) 
are proportionality constants that describe the relationship between the 
concentration of a substance in aquatic organisms and its concentration 
in the ambient water. For the Guidance in this part, BAFs, rather than 
BCFs, are used to calculate Tier I criteria for human health and 
wildlife and Tier II values for human health because they better account 
for the total exposure of aquatic organisms to chemicals.
    C. For organic chemicals, baseline BAFs can be derived using four 
methods. Measured baseline BAFs are derived from field-measured BAFs; 
predicted baseline BAFs are derived using biota-sediment accumulation 
factors (BSAFs) or are derived by multiplying a laboratory-measured or 
predicted BCF by a food-chain multiplier (FCM). The lipid content of the 
aquatic organisms is used to account for partitioning of organic 
chemicals within organisms so that data from different tissues and 
species can be integrated. In addition, the baseline BAF is based on the 
concentration of freely dissolved organic chemicals in the ambient water 
to facilitate extrapolation from one water to another.
    D. For inorganic chemicals, baseline BAFs can be derived using two 
of the four methods. Baseline BAFs are derived using either field-
measured BAFs or by multiplying laboratory-measured BCFs by a FCM. For 
inorganic chemicals, BAFs are assumed to equal BCFs (i.e., the FCM is 
1.0), unless chemical-specific biomagnification data support using a FCM 
other than 1.0.
    E. Because both humans and wildlife consume fish from both trophic 
levels 3 and 4,

[[Page 639]]

two baseline BAFs are needed to calculate either a human health 
criterion or value or a wildlife criterion for a chemical. When 
appropriate, ingestion through consumption of invertebrates, plants, 
mammals, and birds in the diet of wildlife species to be protected may 
be taken into account.

                             II. Definitions

    Baseline BAF. For organic chemicals, a BAF that is based on the 
concentration of freely dissolved chemical in the ambient water and 
takes into account the partitioning of the chemical within the organism; 
for inorganic chemicals, a BAF that is based on the wet weight of the 
tissue.
    Baseline BCF. For organic chemicals, a BCF that is based on the 
concentration of freely dissolved chemical in the ambient water and 
takes into account the partitioning of the chemical within the organism; 
for inorganic chemicals, a BCF that is based on the wet weight of the 
tissue.
    Bioaccumulation. The net accumulation of a substance by an organism 
as a result of uptake from all environmental sources.
    Bioaccumulation factor (BAF). The ratio (in L/kg) of a substance's 
concentration in tissue of an aquatic organism to its concentration in 
the ambient water, in situations where both the organism and its food 
are exposed to and the ratio does not change substantially over time.
    Bioconcentration. The net accumulation of a substance by an aquatic 
organism as a result of uptake directly from the ambient water through 
gill membranes or other external body surfaces.
    Bioconcentration factor (BCF). The ratio (in L/kg) of a substance's 
concentration in tissue of an aquatic organism to its concentration in 
the ambient water, in situations where the organism is exposed through 
the water only and the ratio does not change substantially over time.
    Biota-sediment accumulation factor (BSAF). The ratio (in kg of 
organic carbon/kg of lipid) of a substance's lipid-normalized 
concentration in tissue of an aquatic organism to its organic carbon-
normalized concentration in surface sediment, in situations where the 
ratio does not change substantially over time, both the organism and its 
food are exposed, and the surface sediment is representative of average 
surface sediment in the vicinity of the organism.
    Depuration. The loss of a substance from an organism as a result of 
any active or passive process.
    Food-chain multiplier (FCM). The ratio of a BAF to an appropriate 
BCF.
    Octanol-water partition coefficient (KOW). The ration of the 
concentration of a substance in the n-octanol phase to its concentration 
in the aqueous phase in an equilibrated two-phase octanol-water system. 
For log KOW, the log of the octanol-water partition 
coefficient is a base 10 logarithm.
    Uptake. Acquisition of a substance from the environment by an 
organism as a result of any active or passive process.

                    III. Review and Selection of Data

    A. Data Sources. Measured BAFs, BSAFs and BCFs are assembled from 
available sources including the following:
    1. EPA Ambient Water Quality Criteria documents issued after January 
1, 1980.
    2. Published scientific literature.
    3. Reports issued by EPA or other reliable sources.
    4. Unpublished data.
    One useful source of references is the Aquatic Toxicity Information 
Retrieval (AQUIRE) database.
    B. Field-Measured BAFs. The following procedural and quality 
assurance requirements shall be met for field-measured BAFs:
    1. The field studies used shall be limited to those conducted in the 
Great Lakes System with fish at or near the top of the aquatic food 
chain (i.e., in trophic levels 3 and/or 4).
    2. The trophic level of the fish species shall be determined.
    3. The site of the field study should not be so unique that the BAF 
cannot be extrapolated to other locations where the criteria and values 
will apply.
    4. For organic chemicals, the percent lipid shall be either measured 
or reliably estimated for the tissue used in the determination of the 
BAF.
    5. The concentration of the chemical in the water shall be measured 
in a way that can be related to particulate organic carbon (POC) and/or 
dissolved organic carbon (DOC) and should be relatively constant during 
the steady-state time period.
    6. For organic chemicals with log KOW greater than four, 
the concentrations of POC and DOC in the ambient water shall be either 
measured or reliably estimated.
    7. For inorganic and organic chemicals, BAFs shall be used only if 
they are expressed on a wet weight basis; BAFs reported on a dry weight 
basis cannot be converted to wet weight unless a conversion factor is 
measured or reliably estimated for the tissue used in the determination 
of the BAF.
    C. Field-Measured BSAFs. The following procedural and quality 
assurance requirements shall be met for field-measured BSAFs:
    1. The field studies used shall be limited to those conducted in the 
Great Lakes System with fish at or near the top of the aquatic food 
chain (i.e., in trophic levels 3 and/or 4).
    2. Samples of surface sediments (0-1 cm is ideal) shall be from 
locations in which there is net deposition of fine sediment and is 
representative of average surface sediment in the vicinity of the 
organism.

[[Page 640]]

    3. The KOW s used shall be acceptable quality as 
described in section III.F below.
    4. The site of the field study should not be so unique that the 
resulting BAF cannot be extrapolated to other locations where the 
criteria and values will apply.
    5. The tropic level of the fish species shall be determined.
    6. The percent lipid shall be either measured or reliably estimated 
for the tissue used in the determination of the BAF.
    D. Laboratory-Measured BCFs. The following procedural and quality 
assurance requirements shall be met for laboratory-measured BCFs:
    1. The test organism shall not be diseased, unhealthy, or adversely 
affected by the concentration of the chemical.
    2. The total concentration of the chemical in the water shall be 
measured and should be relatively constant during the steady-state time 
period.
    3. The organisms shall be exposed to the chemical using a flow-
through or renewal procedure.
    4. For organic chemicals, the percent lipid shall be either measured 
or reliably estimated for the tissue used in the determination of the 
BCF.
    5. For organic chemicals with log KOW greater than four, 
the concentrations of POC and DOC in the test solution shall be either 
measured or reliably estimated.
    6. Laboratory-measured BCFs should be determined using fish species, 
but BCFs determined with molluscs and other invertebrates may be used 
with caution. For example, because invertebrates metabolize some 
chemicals less efficiently than vertebrates, a baseline BCF determined 
for such a chemical using invertebrates is expected to be higher than a 
comparable baseline BCF determined using fish.
    7. If laboratory-measured BCFs increase or decrease as the 
concentration of the chemical increases in the test solutions in a 
bioconcentration test, the BCF measured at the lowest test concentration 
that is above concentrations existing in the control water shall be used 
(i.e., a BCF should be calculated from a control treatment). The 
concentrations of an inorganic chemical in a bioconcentration test 
should be greater than normal background levels and greater than levels 
required for normal nutrition of the test species if the chemical is a 
micronutrient, but below levels that adversely affect the species. 
Bioaccumulation of an inorganic chemical might be overestimated if 
concentrations are at or below normal background levels due to, for 
example, nutritional requirements of the test organisms.
    8. For inorganic and organic chemicals, BCFs shall be used only if 
they are expressed on a wet weight basis. BCFs reported on a dry weight 
basis cannot be converted to wet weight unless a conversion factor is 
measured or reliably estimated for the tissue used in the determination 
of the BAF.
    9. BCFs for organic chemicals may be based on measurement or 
radioactivity only when the BCF is intended to include metabolites or 
when there is confidence that there is no interference due to 
metabolites.
    10. The calculation of the BCF must appropriately address growth 
dilution.
    11. Other aspects of the methodology used should be similar to those 
described by ASTM (1990).
    E. Predicted BCFs. The following procedural and quality assurance 
requirements shall be met for predicted BCFs:
    1. The KOW used shall be of acceptable quality as 
described in section III.F below.
    2. The predicted baseline BCF shall be calculated using the 
equation: predicted baseline BCF = KOW
    where:
    KOW = octanol-water partition coefficient.
    F. Octanol-Water Partition Coefficient (KOW). 1. The value of 
KOW used for an organic chemical shall be determined by

    2. The CLOGP program is a computer program available from Pomona 
College. A value of KOW that seems to be different from the 
others should be considered an outlier and not used. The value of 
KOW used for an organic chemical shall be the geometric mean 
of the available KOW s with highest priority or can be 
calculated from the arithmetic mean of the available log KOW 
with the

[[Page 641]]

highest priority. Because it is an intermediate value in the derivation 
of a BAF, the value used for the KOW of a chemical should not 
be rounded to fewer than three significant digits and a value for log 
KOW should not be rounded to fewer than three significant 
digits after the decimal point.
    G. This methodology provides overall guidance for the derivation of 
BAFs, but it cannot cover all the decisions that must be made in the 
review and selection of acceptable data. Professional judgment is 
required throughout the process. A degree of uncertainty is associated 
with the determination of any BAF, BSAF, BCF or KOW. The 
amount of uncertainty in a baseline BAF depends on both the quality of 
data available and the method used to derive the BAF.
    H. Hereinafter in this methodology, the terms BAF, BSAF, BCF and 
KOW refer to ones that are consistent with the procedural and 
quality assurance requirements given above.

               IV. Four Methods for Deriving Baseline BAFs

    Baseline BAFs shall be derived using the following four methods, 
which are listed from most preferred to least preferred:
    A. A measured baseline BAF for an organic or inorganic chemical 
derived from a field study of acceptable quality.
    B. A predicted baseline BAF for an organic chemical derived using 
field-measured BSAFs of acceptable quality.
    C. A predicted baseline BAF for an organic or inorganic chemical 
derived from a BCF measured in a laboratory study of acceptable quality 
and a FCM.
    D. A predicted baseline BAF for an organic chemical derived from a 
KOW of acceptable quality and a FCM.
    For comparative purposes, baseline BAFs should be derived for each 
chemical by as many of the four methods as available data allow.

          V. Calculation of Baseline BAFs for Organic Chemicals

    A. Lipid Normalization. 1. It is assumed that BAFs and BCFs for 
organic chemicals can be extrapolated on the basis of percent lipid from 
one tissue to another and from one aquatic species to another in most 
cases.
    2. Because BAFs and BCFs for organic chemicals are related to the 
percent lipid, it does not make any difference whether the tissue sample 
is whole body or edible portion, but both the BAF (or BCF) and the 
percent lipid must be determined for the same tissue. The percent lipid 
of the tissue should be measured during the BAF or BCF study, but in 
some cases it can be reliably estimated from measurements on tissue from 
other organisms. If percent lipid is not reported for the test organisms 
in the original study, it may be obtained from the author; or, in the 
case of a laboratory study, lipid data for the same or a comparable 
laboratory population of test organisms that were used in the original 
study may be used.
    3. The lipid-normalized concentration, Cl, of a chemical 
in tissue is defined using the following equation:
[GRAPHIC] [TIFF OMITTED] TR23MR95.100

Where:

CB = concentration of the organic chemical in the tissue of 
          aquatic biota (either whole organism or specified tissue) 
          ([micro] g/g).
fl = fraction of the tissue that is lipid.

    B. Bioavailability. By definition, baseline BAFs and BCFs for 
organic chemicals, whether measured or predicted are based on the 
concentration of the chemical that is freely dissolved in the ambient 
water in order to account for bioavailability. For the purposes of this 
Guidance in this part, the relationship between the total concentration 
of the chemical in the water (i.e., that which is freely dissolved plus 
that which is sorbed to particulate organic carbon or to dissolved 
organic carbon) to the freely dissolved concentration of the chemical in 
the ambient water shall be calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR23MR95.101

Where:

C\fd\w = freely dissolved concentration of the organic 
          chemical in the ambient water;
C\t\w = total concentration of the organic chemical in the 
          ambient water;
ffd = fraction of the total chemical in the ambient water 
          that is freely dissolved.

    The fraction of the total chemical in the ambient water that is 
freely dissolved, ffd, shall be calculated using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TR23MR95.102

Where:

DOC = concentration of dissolved organic carbon, kg of dissolved organic 
          carbon/L of water.
KOW = octanol-water partition coefficient of the chemical.
POC = concentration of particulate organic carbon, kg of particulate 
          organic carbon/L of water.


[[Page 642]]


    C. Food-Chain Multiplier. In the absence of a field-measured BAF or 
a predicted BAF derived from a BSAF, a FCM shall be used to calculate 
the baseline BAF for trophic levels 3 and 4 from a laboratory-measured 
or predicted BCF. For an organic chemical, the FCM used shall be derived 
from Table B-1 using the chemical's log KOW and linear 
interpolation. A FCM greater than 1.0 applies to most organic chemicals 
with a log KOW of four or more. The trophic level used shall 
take into account the age or size of the fish species consumed by the 
human, avian or mammalian predator because, for some species of fish, 
the young are in trophic level 3 whereas the adults are in trophic level 
4.
    D. Calculation of a Baseline BAF from a Field-Measured BAF. A 
baseline BAF shall be calculated from a field-measured BAF of acceptable 
quality using the following equation:
[GRAPHIC] [TIFF OMITTED] TR23MR95.103

Where:

BAF\t\T = BAF based on total concentration in tissue and 
          water.
fl = fraction of the tissue that is lipid.
ffd = fraction of the total chemical that is freely dissolved 
          in the ambient water.

The trophic level to which the baseline BAF applies is the same as the 
trophic level of the organisms used in the determination of the field-
measured BAF. For each trophic level, a species mean measured baseline 
BAF shall be calculated as the geometric mean if more than one measured 
baseline BAF is available for a given species. For each trophic level, 
the geometric mean of the species mean measured baseline BAFs shall be 
calculated. If a baseline BAF based on a measured BAF is available for 
either trophic level 3 or 4, but not both, a measured baseline BAF for 
the other trophic level shall be calculated using the ratio of the FCMs 
that are obtained by linear interpolation from Table B-1 for the 
chemical.
    E. Calculation of a Baseline BAF from a Field-Measured BSAF. 1. A 
baseline BAF for organic chemical ``i'' shall be calculated from a 
field-measured BSAF of acceptable quality using the following equation:
[GRAPHIC] [TIFF OMITTED] TR23MR95.105

Where:

(BSAF)i = BSAF for chemical ``i''.
(BSAF)r = BSAF for the reference chemical ``r''.
(KOW)i = octanol-water partition coefficient for 
          chemical ``i''.
(KOW)r = octanol-water partition coefficient for 
          the reference chemical ``r''.

    2. A BSAF shall be calculated using the following equation:
    [GRAPHIC] [TIFF OMITTED] TR23MR95.106
    
Where:

Ct = the lipid-normalized concentration of the chemical in 
          tissue.
CSOC = the organic carbon-normalized concentration of the 
          chemical in sediment.
    3. The organic carbon-normalized concentration of a chemical in 
sediment, CSOC, shall be calculated using the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR23MR95.107

Where:
CS = concentration of chemical in sediment ([micro] g/g 
          sediment).
fOC = fraction of the sediment that is organic carbon.

    4. Predicting BAFs from BSAFs requires data from a steady-state (or 
near steady-state) condition between sediment and ambient water for both 
a reference chemical ``r'' with a field-measured BAFl fd and 
other chemicals ``n = i'' for which BSAFs are to be determined.

[[Page 643]]

    5. The trophic level to which the baseline BAF applies is the same 
as the trophic level of the organisms used in the determination of the 
BSAF. For each trophic level, a species mean baseline BAF shall be 
calculated as the geometric mean if more than one baseline BAF is 
predicted from BSAFs for a given species. For each trophic level, the 
geometric mean of the species mean baseline BAFs derived using BSAFs 
shall be calculated.
    6. If a baseline BAF based on a measured BSAF is available for 
either trophic level 3 or 4, but not both, a baseline BAF for the other 
trophic level shall be calculated using the ratio of the FCMs that are 
obtained by linear interpolation from Table B-1 for the chemical.
    F. Calculation of a Baseline BAF from a Laboratory-Measured BCF. A 
baseline BAF for trophic level 3 and a baseline BAF for trophic level 4 
shall be calculated from a laboratory-measured BCF of acceptable quality 
and a FCM using the following equation:
[GRAPHIC] [TIFF OMITTED] TR23MR95.108

Where:

BCF\t\T = BCF based on total concentration in tissue and 
          water.
fl = fraction of the tissue that is lipid.
ffd = fraction of the total chemical in the test water that 
          is freely dissolved.
FCM = the food-chain multiplier obtained from Table B-1 by linear 
          interpolation for trophic level 3 or 4, as necessary.

For each trophic level, a species mean baseline BAF shall be calculated 
as the geometric mean if more than one baseline BAF is predicted from 
laboratory-measured BCFs for a given species. For each trophic level, 
the geometric mean of the species mean baseline BAFs based on 
laboratory-measured BCFs shall be calculated.
    G. Calculation of a Baseline BAF from an Octanol-Water Partition 
Coefficient. A baseline BAF for trophic level 3 and a baseline BAF for 
trophic level 4 shall be calculated from a KOW of acceptable 
quality and a FCM using the following equation:
    Baseline BAF = (FCM) (predicted baseline BCF) = (FCM) 
(KOW)

Where:

FCM = the food-chain multiplier obtained from Table B-1 by linear 
          interpolation for trophic level 3 or 4, as necessary.
KOW = octanol-water partition coefficient.

        VI. Human Health and Wildlife BAFs for Organic Chemicals

    A. To calculate human health and wildlife BAFs for an organic 
chemical, the KOW of the chemical shall be used with a POC 
concentration of 0.00000004 kg/L and a DOC concentration of 0.000002 kg/
L to yield the fraction freely dissolved:
[GRAPHIC] [TIFF OMITTED] TR23MR95.109


[[Page 644]]


    B. The human health BAFs for an organic chemical shall be calculated 
using the following equations:
    For trophic level 3:
    [GRAPHIC] [TIFF OMITTED] TR23MR95.110
    
    For trophic level 4:
    [GRAPHIC] [TIFF OMITTED] TR23MR95.111
    
Where:
    0.0182 and 0.0310 are the standardized fraction lipid values for 
trophic levels 3 and 4, respectively, that are used to derive human 
health criteria and values for the GLI.
    C. The wildlife BAFs for an organic chemical shall be calculated 
using the following equations:
    For trophic level 3:
    [GRAPHIC] [TIFF OMITTED] TR23MR95.112
    
    For trophic level 4:
    [GRAPHIC] [TIFF OMITTED] TR23MR95.113
    
Where:
    0.0646 and 0.1031 are the standardized fraction lipid values for 
trophic levels 3 and 4, respectively, that are used to derive wildlife 
criteria for the GLI.

       VII. Human Health and Wildlife BAFs for Inorganic Chemicals

    A. For inorganic chemicals, the baseline BAFs for trophic levels 3 
and 4 are both assumed to equal the BCF determined for the chemical with 
fish, i.e., the FCM is assumed to be 1 for both trophic levels 3 and 4. 
However, a FCM greater than 1 might be applicable to some metals, such 
as mercury, if, for example, an organometallic form of the metal 
biomagnifies.
    B. BAFs for Human Health Criteria and Values.
    1. Measured BAFs and BCFs used to determine human health BAFs for 
inorganic chemicals shall be based on edible tissue (e.g., muscle) of 
freshwater fish unless it is demonstrated that whole-body BAFs or BCFs 
are similar to edible-tissue BAFs or BCFs. BCFs and BAFs based on 
measurements of aquatic plants and invertebrates should not be used in 
the derivation of human health criteria and values.
    2. If one or more field-measured baseline BAFs for an inorganic 
chemical are available from studies conducted in the Great Lakes System 
with the muscle of fish:
    a. For each trophic level, a species mean measured baseline BAF 
shall be calculated as the geometric mean if more than one measured BAF 
is available for a given species; and
    b. For each trophic level, the geometric mean of the species mean 
measured baseline BAFs shall be used as the human health BAF for that 
chemical.
    3. If an acceptable measured baseline BAF is not available for an 
inorganic chemical and one or more acceptable edible-portion laboratory-
measured BCFs are available for the chemical, a predicted baseline BAF 
shall be calculated by multiplying the geometric mean of the BCFs times 
a FCM. The FCM will be 1.0 unless chemical-specific biomagnification 
data support using a multiplier other than 1.0. The predicted baseline 
BAF shall be used as the human health BAF for that chemical.

[[Page 645]]

    C. BAFs for Wildlife Criteria.
    1. Measured BAFs and BCFs used to determine wildlife BAFs for 
inorganic chemicals shall be based on whole-body freshwater fish and 
invertebrate data unless it is demonstrated that edible-tissue BAFs or 
BCFs are similar to whole-body BAFs or BCFs.
    2. If one or more field-measured baseline BAFs for an inorganic 
chemical are available from studies conducted in the Great Lakes System 
with whole body of fish or invertebrates:
    a. For each trophic level, a species mean measured baseline BAF 
shall be calculated as the geometric mean if more than one measured BAF 
is available for a given species.
    b. For each trophic level, the geometric mean of the species mean 
measured baseline BAFs shall be used as the wildlife BAF for that 
chemical.
    3. If an acceptable measured baseline BAF is not available for an 
inorganic chemical and one or more acceptable whole-body laboratory-
measured BCFs are available for the chemical, a predicted baseline BAF 
shall be calculated by multiplying the geometric mean of the BCFs times 
a FCM. The FCM will be 1.0 unless chemical-specific biomagnification 
data support using a multiplier other than 1.0. The predicted baseline 
BAF shall be used as the wildlife BAF for that chemical.

                           VIII. Final Review

    For both organic and inorganic chemicals, human health and wildlife 
BAFs for both trophic levels shall be reviewed for consistency with all 
available data concerning the bioaccumulation, bioconcentration, and 
metabolism of the chemical. For example, information concerning octanol-
water partitioning, molecular size, or other physicochemical properties 
that might enhance or inhibit bioaccumulation should be considered for 
organic chemicals. BAFs derived in accordance with this methodology 
should be modified if changes are justified by available data.

   Sec. Appendix C to Part 132--Great Lakes Water Quality Initiative 
    Methodologies for Development of Human Health Criteria and Values

    Great Lakes States and Tribes shall adopt provisions consistent with 
(as protective as) this appendix.

                             I. Introduction

    Great Lakes States and Tribes shall adopt provisions consistent with 
this appendix C to ensure protection of human health.
    A. Goal. The goal of the human health criteria for the Great Lakes 
System is the protection of humans from unacceptable exposure to 
toxicants via consumption of contaminated fish and drinking water and 
from ingesting water as a result of participation in water-oriented 
recreational activities.
    B. Definitions.
    Acceptable daily exposure (ADE). An estimate of the maximum daily 
dose of a substance which is not expected to result in adverse noncancer 
effects to the general human population, including sensitive subgroups.
    Adverse effect. Any deleterious effect to organisms due to exposure 
to a substance. This includes effects which are or may become 
debilitating, harmful or toxic to the normal functions of the organism, 
but does not include non-harmful effects such as tissue discoloration 
alone or the induction of enzymes involved in the metabolism of the 
substance.
    Carcinogen. A substance which causes an increased incidence of 
benign or malignant neoplasms, or substantially decreases the time to 
develop neoplasms, in animals or humans. The classification of 
carcinogens is discussed in section II.A of appendix C to part 132.
    Human cancer criterion (HCC). A Human Cancer Value (HCV) for a 
pollutant that meets the minimum data requirements for Tier I specified 
in appendix C.
    Human cancer value (HCV). The maximum ambient water concentration of 
a substance at which a lifetime of exposure from either: drinking the 
water, consuming fish from the water, and water-related recreation 
activities; or consuming fish from the water, and water-related 
recreation activities, will represent a plausible upper-bound risk of 
contracting cancer of one in 100,000 using the exposure assumptions 
specified in the Methodologies for the Development of Human Health 
Criteria and Values in appendix C of this part.
    Human noncancer criterion (HNC). A Human Noncancer Value (HNV) for a 
pollutant that meets the minimum data requirements for Tier I specified 
in appendix C of this part.
    Human noncancer value (HNV). The maximum ambient water concentration 
of a substance at which adverse noncancer effects are not likely to 
occur in the human population from lifetime exposure via either: 
drinking the water, consuming fish from the water, and water-related 
recreation activities; or consuming fish from the water, and water-
related recreation activities using the Methodologies for the 
Development of Human Health criteria and Values in appendix C of this 
part.
    Linearized multi-stage model. A conservative mathematical model for 
cancer risk assessment. This model fits linear dose-response curves to 
low doses. It is consistent with a no-threshold model of carcinogenesis, 
i.e., exposure to even a very small amount of the substance is assumed 
to produce a finite increased risk of cancer.
    Lowest observed adverse effect level (LOAEL). The lowest tested dose 
or concentration of a substance which resulted in an observed adverse 
effect in exposed test organisms when all higher doses or concentrations 
resulted in the same or more severe effects.
    No observed adverse effect level (NOAEL). The highest tested dose or 
concentration of a substance which resulted in no observed adverse 
effect in exposed test organisms where higher doses or concentrations 
resulted in an adverse effect.
    Quantitative structure activity relationship (OSAR) or structure 
activity relationship (SAR). A mathematical relationship between a 
property (activity) of a chemical and a number of descriptors of the 
chemical. These descriptors are chemical or physical characteristics 
obtained experimentally or predicted from the structure of the chemical.
    Relative source contribution (RSC). The factor (percentage) used in 
calculating an HNV or HNC to account for all sources of exposure to a 
contaminant. The RSC reflects the percent of total exposure which can be 
attributed to surface water through water intake and fish consumption.
    Risk associated dose (RAD). A dose of a known or presumed 
carcinogenic substance in (mg/kg/day) which, over a lifetime of 
exposure, is estimated to be associated with a plausible upper bound 
incremental cancer risk equal to one in 100,000.
    Slope factor. Also known as q1*, slope factor is the 
incremental rate of cancer development calculated through use of a 
linearized multistage model or other appropriate model. It is expressed 
in (mg/kg/day) of exposure to the chemical in question.
    Threshold effect. An effect of a substance for which there is a 
theoretical or empirically established dose or concentration below which 
the effect does not occur.
    Uncertainty factor (UF). One of several numeric factors used in 
operationally deriving criteria from experimental data to account for 
the quality or quantity of the available data.

[[Page 647]]

    C. Level of Protection. The criteria developed shall provide a level 
of protection likely to be without appreciable risk of carcinogenic and/
or noncarcinogenic effects. Criteria are a function of the level of 
designated risk or no adverse effect estimation, selection of data and 
exposure assumptions. Ambient criteria for single carcinogens shall not 
be set at a level representing a lifetime upper-bound incremental risk 
greater than one in 100,000 of developing cancer using the hazard 
assessment techniques and exposure assumptions described herein. 
Criteria affording protection from noncarcinogenic effects shall be 
established at levels that, taking into account uncertainties, are 
considered likely to be without an appreciable risk of adverse human 
health effects (i.e., acute, subchronic and chronic toxicity including 
reproductive and developmental effects) during a lifetime of exposure, 
using the risk assessment techniques and exposure assumptions described 
herein.
    D. Two-tiered Classification. Chemical concentration levels in 
surface water protective of human health shall be derived based on 
either a Tier I or Tier II classification. The two Tiers are primarily 
distinguished by the amount of toxicity data available for deriving the 
concentration levels and the quantity and quality of data on 
bioaccumulation.

                      II. Minimum Data Requirements

    The best available toxicity data on the adverse health effects of a 
chemical and the best data on bioaccumulation factors shall be used when 
developing human health Tier I criteria or Tier II values. The best 
available toxicity data shall include data from well-conducted 
epidemiologic and/or animal studies which provide, in the case of 
carcinogens, an adequate weight of evidence of potential human 
carcinogenicity and, in the case of noncarcinogens, a dose-response 
relationship involving critical effects biologically relevant to humans. 
Such information should be obtained from the EPA Integrated Risk 
Information System (IRIS) database, the scientific literature, and other 
informational databases, studies and/or reports containing adverse 
health effects data of adequate quality for use in this procedure. 
Strong consideration shall be given to the most currently available 
guidance provided by IRIS in deriving criteria or values, supplemented 
with any recent data not incorporated into IRIS. When deviations from 
IRIS are anticipated or considered necessary, it is strongly recommended 
that such actions be communicated to the EPA Reference Dose (RfD) and/or 
the Cancer Risk Assessment Verification Endeavor (CRAVE) workgroup 
immediately. The best available bioaccumulation data shall include data 
from field studies and well-conducted laboratory studies.
    A. Carcinogens. Tier I criteria and Tier II values shall be derived 
using the methodologies described in section III.A of this appendix when 
there is adequate evidence of potential human carcinogenic effects for a 
chemical. It is strongly recommended that the EPA classification system 
for chemical carcinogens, which is described in the 1986 EPA Guidelines 
for Carcinogenic Risk Assessment (U.S. EPA, 1986), or future 
modifications thereto, be used in determining whether adequate evidence 
of potential carcinogenic effects exists. Carcinogens are classified, 
depending on the weight of evidence, as either human carcinogens, 
probable human carcinogens, or possible human carcinogens. The human 
evidence is considered inadequate and therefore the chemical cannot be 
classified as a human carcinogen, if one of two conditions exists: (a) 
there are few pertinent data, or (b) the available studies, while 
showing evidence of association, do not exclude chance, bias, or 
confounding and therefore a casual interpretation is not credible. The 
animal evidence is considered inadequate, and therefore the chemical 
cannot be classified as a probable or possible human carcinogen, when, 
because of major qualitative or quantitative limitations, the evidence 
cannot be interpreted as showing either the presence or absence of a 
carcinogenic effect.
    Chemicals are described as ``human carcinogens'' when there is 
sufficient evidence from epidemiological studies to support a causal 
association between exposure to the chemicals and cancer. Chemicals 
described as ``probable human carcinogens'' include chemicals for which 
the weight of evidence of human carcinogenicity based on epidemiological 
studies is limited. Limited human evidence is that which indicates that 
a causal interpretation is credible, but that alternative explanations, 
such as chance, bias, or confounding, cannot adequately be excluded. 
Probable human carcinogens are also agents for which there is sufficient 
evidence from animal studies and for which there is inadequate evidence 
or no data from epidemiologic studies. Sufficient animal evidence is 
data which indicates that there is an increased incidence of malignant 
tumors or combined malignant and benign tumors: (a) in multiple species 
or strains; (b) in multiple experiments (e.g., with different routes of 
administration or using different dose levels); or (c) to an unusual 
degree in a single experiment with regard to high incidence, unusual 
site or type of tumor, or early age at onset. Additional evidence may be 
provided by data on dose-response effects, as well as information from 
short-term tests (such as mutagenicity/genotoxicity tests which help 
determine whether the chemical interacts directly with DNA) or on 
chemical structure, metabolism or mode of action.

[[Page 648]]

    ``Possible human carcinogens'' are chemicals with limited evidence 
of carcinogenicity in animals in the absence of human data. Limited 
animal evidence is defined as data which suggests a carcinogenic effect 
but are limited because: (a) The studies involve a single species, 
strain, or experiment and do not meet criteria for sufficient evidence 
(see preceding paragraph); or (b) the experiments are restricted by 
inadequate dosage levels, inadequate duration of exposure to the agent, 
inadequate period of follow-up, poor survival, too few animals, or 
inadequate reporting; or (c) the studies indicate an increase in the 
incidence of benign tumors only. More specifically, this group can 
include a wide variety of evidence, e.g., (a) a malignant tumor response 
in a single well-conducted experiment that does not meet conditions for 
sufficient evidence, (b) tumor response of marginal statistical 
significance in studies having inadequate design or reporting, (c) 
benign but not malignant tumors with an agent showing no response in a 
variety of short-term tests for mutagenicity, and (d) response of 
marginal statistical significance in a tissue known to have a high or 
variable background rate.
    1. Tier I: Weight of evidence of potential human carcinogenic 
effects sufficient to derive a Tier I HCC shall generally include human 
carcinogens, probable human carcinogens and can include, on a case-by-
case basis, possible human carcinogens if studies have been well-
conducted albeit based on limited evidence, when compared to studies 
used in classifying human and probable human carcinogens. The decision 
to use data on a possible human carcinogen for deriving Tier I criteria 
shall be a case-by-case determination. In determining whether to derive 
a Tier I HCC, additional evidence that shall be considered includes but 
is not limited to available information on mode of action, such as 
mutagenicity/genotoxicity (determinations of whether the chemical 
interacts directly with DNA), structure activity, and metabolism.
    2. Tier II: Weight of evidence of possible human carcinogenic 
effects sufficient to derive a Tier II human cancer value shall include 
those possible human carcinogens for which there are at a minimum, data 
sufficient for quantitative risk assessment, but for which data are 
inadequate for Tier I criterion development due to a tumor response of 
marginal statistical significance or inability to derive a strong dose-
response relationship. In determining whether to derive Tier II human 
cancer values, additional evidence that shall be considered includes but 
is not limited to available information on mode of action such as 
mutagenicity/genotoxicity (determinations of whether the chemical 
interacts directly with DNA), structure activity and metabolism. As with 
the use of data on possible human carcinogens in developing Tier I 
criteria, the decision to use data on possible human carcinogens to 
derive Tier II values shall be made on a case-by-case basis.
    B. Noncarcinogens. All available toxicity data shall be evaluated 
considering the full range of possible health effects of a chemical, 
i.e., acute/subacute, chronic/subchronic and reproductive/developmental 
effects, in order to best describe the dose-response relationship of the 
chemical, and to calculate human noncancer criteria and values which 
will protect against the most sensitive endpoint(s) of toxicity. 
Although it is desirable to have an extensive database which considers a 
wide range of possible adverse effects, this type of data exists for a 
very limited number of chemicals. For many others, there is a range in 
quality and quantity of data available. To assure minimum reliability of 
criteria and values, it is necessary to establish a minimum database 
with which to develop Tier I criteria or Tier II values. The following 
represent the minimum data sets necessary for this procedure.
    1. Tier I: The minimum data set sufficient to derive a Tier I human 
HNC shall include at least one well-conducted epidemiologic study or 
animal study. A well-conducted epidemiologic study for a Tier I HNC must 
quantify exposure level(s) and demonstrate positive association between 
exposure to a chemical and adverse effect(s) in humans. A well-conducted 
study in animals must demonstrate a dose response relationship involving 
one or more critical effect(s) biologically relevant to humans. (For 
example, study results from an animal whose pharmacokinetics and 
toxicokinetics match those of a human would be considered most 
biologically relevant.) Ideally, the duration of a study should span 
multiple generations of exposed test species or at least a major portion 
of the lifespan of one generation. This type of data is currently very 
limited. By the use of uncertainty adjustments, shorter term studies 
(such as 90-day subchronic studies) with evaluation of more limited 
effect(s) may be used to extrapolate to longer exposures or to account 
for a variety of adverse effects. For Tier I criteria developed pursuant 
to this procedure, such a limited study must be conducted for at least 
90 days in rodents or 10 percent of the lifespan of other appropriate 
test species and demonstrate a no observable adverse effect level 
(NOAEL). Chronic studies of one year or longer in rodents or 50 percent 
of the lifespan or greater in other appropriate test species that 
demonstrate a lowest observable adverse effect level (LOAEL) may be 
sufficient for use in Tier I criterion derivation if the effects 
observed at the LOAEL were relatively mild and reversible as compared to 
effects at higher doses. This does not preclude the use of a LOAEL from 
a study (of chronic duration) with only one or two doses if the effects

[[Page 649]]

observed appear minimal when compared to effect levels observed at 
higher doses in other studies.
    2. Tier II: When the minimum data for deriving Tier I criteria are 
not available to meet the Tier I data requirements, a more limited 
database may be considered for deriving Tier II values. As with Tier I 
criteria, all available data shall be considered and ideally should 
address a range of adverse health effects with exposure over a 
substantial portion of the lifespan (or multiple generations) of the 
test species. When such data are lacking it may be necessary to rely on 
less extensive data in order to establish a Tier II value. With the use 
of appropriate uncertainty factors to account for a less extensive 
database, the minimum data sufficient to derive a Tier II value shall 
include a NOAEL from at least one well-conducted short-term repeated 
dose study. This study shall be of at least 28 days duration, in animals 
demonstrating a dose-response, and involving effects biologically 
relevant to humans. Data from studies of longer duration (greater than 
28 days) and LOAELs from such studies (greater than 28 days) may be more 
appropriate in some cases for derivation of Tier II values. Use of a 
LOAEL should be based on consideration of the following information: 
severity of effect, quality of the study and duration of the study.
    C. Bioaccumulation factors (BAFs).
    1. Tier I for Carcinogens and Noncarcinogens: To be considered a 
Tier I cancer or noncancer human health criterion, along with satisfying 
the minimum toxicity data requirements of sections II.A.1 and II.B.1 of 
this appendix, a chemical must have the following minimum 
bioaccumulation data. For all organic chemicals either: (a) a field-
measured BAF; (b) a BAF derived using the BSAF methodology; or (c) a 
chemical with a BAF less than 125 regardless of how the BAF was derived. 
For all inorganic chemicals, including organometals such as mercury, 
either: (a) a field-measured BAF or (b) a laboratory-measured BCF.
    2. Tier II for Carcinogens and Noncarcinogens: A chemical is 
considered a Tier II cancer or noncancer human health value if it does 
not meet either the minimum toxicity data requirements of sections 
II.A.1 and II.B.1 of this appendix or the minimum bioaccumulation data 
requirements of section II.C.1 of this appendix.

  III. Principles for Development of Tier I Criteria or Tier II Values

    The fundamental components of the procedure to calculate Tier I 
criteria or Tier II values are the same. However, certain of the aspects 
of the procedure designed to account for short-duration studies or other 
limitations in data are more likely to be relevant in deriving Tier II 
values than Tier I criteria.
    A. Carcinogens.
    1. A non-threshold mechanism of carcinogenesis shall be assumed 
unless biological data adequately demonstrate the existence of a 
threshold on a chemical-specific basis.
    2. All appropriate human epidemiologic data and animal cancer 
bioassay data shall be considered. Data specific to an environmentally 
appropriate route of exposure shall be used. Oral exposure should be 
used preferentially over dermal and inhalation since, in most cases, the 
exposure routes of greatest concern are fish consumption and drinking 
water/incidental ingestion. The risk associated dose shall be set at a 
level corresponding to an incremental cancer risk of one in 100,000. If 
acceptable human epidemiologic data are available for a chemical, it 
shall be used to derive the risk associated dose. If acceptable human 
epidemiologic data are not available, the risk associated dose shall be 
derived from available animal bioassay data. Data from a species that is 
considered most biologically relevant to humans (i.e., responds most 
like humans) is preferred where all other considerations regarding 
quality of data are equal. In the absence of data to distinguish the 
most relevant species, data from the most sensitive species tested, 
i.e., the species showing a carcinogenic effect at the lowest 
administered dose, shall generally be used.
    3. When animal bioassay data are used and a non-threshold mechanism 
of carcinogenicity is assumed, the data are fitted to a linearized 
multistage computer model (e.g., Global '86 or equivalent model). Global 
'86 is the linearized multistage model, derived by Howe, Crump and Van 
Landingham (1986), which EPA uses to determine cancer potencies. The 
upper-bound 95 percent confidence limit on risk (or, the lower 95 
percent confidence limit on dose) at the one in 100,000 risk level shall 
be used to calculate a risk associated dose (RAD). Other models, 
including modifications or variations of the linear multistage model 
which are more appropriate to the available data may be used where 
scientifically justified.
    4. If the duration of the study is significantly less than the 
natural lifespan of the test animal, the slope may be adjusted on a 
case-by-case basis to compensate for latent tumors which were not 
expressed (e.g., U.S. EPA, 1980) In the absence of alternative 
approaches which compensate for study durations significantly less than 
lifetime, the permitting authority may use the process described in the 
1980 National Guidelines (see 45 FR 79352).
    5. A species scaling factor shall be used to account for differences 
between test species and humans. It shall be assumed that milligrams per 
surface area per day is an equivalent dose between species (U.S. EPA, 
1986). All doses presented in mg/kg bodyweight will be converted to an 
equivalent surface area

[[Page 650]]

dose by raising the mg/kg dose to the \2/3\ power. However, if adequate 
pharmacokinetic and metabolism studies are available, these data may be 
factored into the adjustment for species differences on a case-by-case 
basis.
    6. Additional data selection and adjustment decisions must also be 
made in the process of quantifying risk. Consideration must be given to 
tumor selection for modeling, e.g., pooling estimates for multiple tumor 
types and identifying and combining benign and malignant tumors. All 
doses shall be adjusted to give an average daily dose over the study 
duration. Adjustments in the rate of tumor response must be made for 
early mortality in test species. The goodness-of-fit of the model to the 
data must also be assessed.
    7. When a linear, non-threshold dose response relationship is 
assumed, the RAD shall be calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR23MR95.114

Where:

RAD = risk associated dose in milligrams of toxicant per kilogram body 
          weight per day (mg/kg/day).
0.00001 (1 x 10-5) = incremental risk of developing cancer 
          equal to one in 100,000.
q1* = slope factor (mg/kg/day)-1.
    8. If human epidemiologic data and/or other biological data (animal) 
indicate that a chemical causes cancer via a threshold mechanism, the 
risk associated dose may, on a case-by-case basis, be calculated using a 
method which assumes a threshold mechanism is operative.
    B. Noncarcinogens.
    1. Noncarcinogens shall generally be assumed to have a threshold 
dose or concentration below which no adverse effects should be observed. 
Therefore, the Tier I criterion or Tier II value is the maximum water 
concentration of a substance at or below which a lifetime exposure from 
drinking the water, consuming fish caught in the water, and ingesting 
water as a result of participating in water-related recreation 
activities is likely to be without appreciable risk of deleterious 
effects.
    For some noncarcinogens, there may not be a threshold dose below 
which no adverse effects should be observed. Chemicals acting as 
genotoxic teratogens and germline mutagens are thought to possibly 
produce reproductive and/or developmental effects via a genetically 
linked mechanism which may have no threshold. Other chemicals also may 
not demonstrate a threshold. Criteria for these types of chemicals will 
be established on a case-by-case basis using appropriate assumptions 
reflecting the likelihood that no threshold exists.
    2. All appropriate human and animal toxicologic data shall be 
reviewed and evaluated. To the maximum extent possible, data most 
specific to the environmentally relevant route of exposure shall be 
used. Oral exposure data should be used preferentially over dermal and 
inhalation since, in most cases, the exposure routes of greatest concern 
are fish consumption and drinking water/incidental ingestion. When 
acceptable human data are not available (e.g., well-conducted 
epidemiologic studies), animal data from species most biologically 
relevant to humans shall be used. In the absence of data to distinguish 
the most relevant species, data from the most sensitive animal species 
tested, i.e., the species showing a toxic effect at the lowest 
administered dose (given a relevant route of exposure), should generally 
be used.
    3. Minimum data requirements are specified in section II.B of this 
appendix. The experimental exposure level representing the highest level 
tested at which no adverse effects were demonstrated (NOAEL) from 
studies satisfying the provisions of section II.B of this appendix shall 
be used for criteria calculations. In the absence of a NOAEL, the LOAEL 
from studies satisfying the provisions of section II.B of this appendix 
may be used if it is based on relatively mild and reversible effects.
    4. Uncertainty factors shall be used to account for the 
uncertainties in predicting acceptable dose levels for the general human 
population based upon experimental animal data or limited human data.
    a. An uncertainty factor of 10 shall generally be used when 
extrapolating from valid experimental results from studies on prolonged 
exposure to average healthy humans. This 10-fold factor is used to 
protect sensitive members of the human population.
    b. An uncertainty factor of 100 shall generally be used when 
extrapolating from valid results of long-term studies on experimental 
animals when results of studies of human exposure are not available or 
are inadequate. In comparison to a, above, this represents an additional 
10-fold uncertainty factor in extrapolating data from the average animal 
to the average human.
    c. An uncertainty factor of up to 1000 shall generally be used when 
extrapolating from animal studies for which the exposure duration is 
less than chronic, but greater than subchronic (e.g., 90 days or more in 
length), or when other significant deficiencies in study quality are 
present, and when useful long-term human data are not available. In 
comparison to b, above, this represents an additional UF of up to 10-
fold for less than chronic, but greater than subchronic, studies.

[[Page 651]]

    d. An UF of up to 3000 shall generally be used when extrapolating 
from animal studies for which the exposure duration is less than 
subchronic (e.g., 28 days). In comparison to b above, this represents an 
additional UF of up to 30-fold for less than subchronic studies (e.g., 
28-day). The level of additional uncertainty applied for less than 
chronic exposures depends on the duration of the study used relative to 
the lifetime of the experimental animal.
    e. An additional UF of between one and ten may be used when deriving 
a criterion from a LOAEL. This UF accounts for the lack of an 
identifiable NOAEL. The level of additional uncertainty applied may 
depend upon the severity and the incidence of the observed adverse 
effect.
    f. An additional UF of between one and ten may be applied when there 
are limited effects data or incomplete sub-acute or chronic toxicity 
data (e.g., reproductive/developmental data). The level of quality and 
quantity of the experimental data available as well as structure-
activity relationships may be used to determine the factor selected.
    g. When deriving an UF in developing a Tier I criterion or Tier II 
value, the total uncertainty, as calculated following the guidance of 
sections 4.a through f, cited above, shall not exceed 10,000 for Tier I 
criteria and 30,000 for Tier II values.
    5. All study results shall be converted, as necessary, to the 
standard unit for acceptable daily exposure of milligrams of toxicant 
per kilogram of body weight per day (mg/kg/day). Doses shall be adjusted 
for continuous exposure (i.e., seven days/week, 24 hours/day, etc.).
    C. Criteria and Value Derivation.
    1. Standard Exposure Assumptions. The following represent the 
standard exposure assumptions used to calculate Tier I criteria and Tier 
II values for carcinogens and noncarcinogens. Higher levels of exposure 
may be assumed by States and Tribes pursuant to Clean Water Act (CWA) 
section 510, or where appropriate in deriving site-specific criteria 
pursuant to procedure 1 in appendix F to part 132.
    BW = body weight of an average human (BW = 70kg).
    WCd = per capita water consumption (both drinking and 
incidental exposure) for surface waters classified as public water 
supplies = two liters/day.
     --or--
    WCr = per capita incidental daily water ingestion for 
surface waters not used as human drinking water sources = 0.01 liters/
day.
    FC = per capita daily consumption of regionally caught freshwater 
fish = 0.015kg/day (0.0036 kg/day for trophic level 3 and 0.0114 kg/day 
for trophic level 4).
    BAF = bioaccumulation factor for trophic level 3 and trophic level 
4, as derived using the BAF methodology in appendix B to part 132.

   Sec. Appendix D to Part 132--Great Lakes Water Quality Initiative 
          Methodology for the Development of Wildlife Criteria

    Great Lakes States and Tribes shall adopt provisions consistent with 
(as protective as) this appendix.

                             I. Introduction

    A. A Great Lakes Water Quality Wildlife Criterion (GLWC) is the 
concentration of a substance which is likely to, if not exceeded, 
protect avian and mammalian wildlife populations inhabiting the Great 
Lakes basin from adverse effects resulting from the ingestion of water 
and aquatic prey taken from surface waters of the Great Lakes System. 
These criteria are based on existing toxicological studies of the 
substance of concern and quantitative information about the exposure of 
wildlife species to the substance (i.e., food and water consumption 
rates). Since toxicological and exposure data for individual wildlife 
species are limited, a GLWC is derived using a methodology similar to 
that used to derive noncancer human health criteria (Barnes and Dourson, 
1988; NAS, 1977; NAS, 1980; U.S. EPA, 1980). Separate avian and 
mammalian values are developed using taxonomic class-specific toxicity 
data and exposure data for five representative Great Lakes basin 
wildlife species. The wildlife species selected are representative of 
avian and mammalian species resident in the Great Lakes basin which are 
likely to experience the highest exposures to bioaccumulative 
contaminants through the aquatic food web; they are the bald eagle, 
herring gull, belted kingfisher, mink, and river otter.
    B. This appendix establishes a methodology which is required when 
developing Tier I wildlife criteria for bioaccumulative chemicals of 
concern (BCCs). The use of the equation provided in the methodology is 
encouraged, but not required, for the development of Tier I criteria or 
Tier II values for pollutants other than those identified in Table 6-A 
for which Tier I criteria or Tier II values are determined to be 
necessary for the protection of wildlife in the Great Lakes basin. A 
discussion of the methodology for deriving Tier II values can be found 
in the

[[Page 653]]

Great Lakes Water Quality Initiative Technical Support Document for 
Wildlife Criteria (Wildlife TSD).
    C. In the event that this methodology is used to develop criteria 
for pollutants other than BCCs, or in the event that the Tier II 
methodology described in the Wildlife TSD is used to derive Tier II 
values, the methodology for deriving bioaccumulation factors under 
appendix B to part 132 must be used in either derivation. For chemicals 
which do not biomagnify to the extent of BCCs, it may be appropriate to 
select different representative species which are better examples of 
species with the highest exposures for the given chemical. The equation 
presented in this methodology, however, is still encouraged. In 
addition, procedure 1 of appendix F of this part describes the 
procedures for calculating site-specific wildlife criteria.
    D. The term ``wildlife value'' (WV) is used to denote the value for 
each representative species which results from using the equation 
presented below, the value obtained from averaging species values within 
a class, or any value derived from application of the site-specific 
procedure provided in procedure 1 of appendix F of this part. The WVs 
calculated for the representative species are used to calculate 
taxonomic class-specific WVs. The WV is the concentration of a substance 
which, if not exceeded, should better protect the taxon in question.
    E. ``Tier I wildlife criterion,'' or ``Tier I criterion'' is used to 
denote the number derived from data meeting the Tier I minimum database 
requirements, and which will be protective of the two classes of 
wildlife. It is synonymous with the term ``GLWC,'' and the two are used 
interchangeably.

         II. Calculation of Wildlife Values for Tier I Criteria

    Table 4 of Part 132 and Table D-1 of this appendix contain criteria 
calculated by EPA using the methodology provided below.
    A. Equation for Avian and Mammalian Wildlife Values. Tier I wildlife 
values for the pollutants designated BCCs pursuant to part 132 are to be 
calculated using the equation presented below.
[GRAPHIC] [TIFF OMITTED] TR23MR95.117

Where:

WV = Wildlife Value in milligrams of substance per liter (mg/L).
TD = Test Dose (TD) in milligrams of substance per kilograms per day 
          (mg/kg-d) for the test species. This shall be either a NOAEL 
          or a LOAEL.
UFA = Uncertainty Factor (UF) for extrapolating toxicity data 
          across species (unitless). A species-specific UF shall be 
          selected and applied to each representative species, 
          consistent with the equation.
UFS = UF for extrapolating from subchronic to chronic 
          exposures (unitless).
UFL = UF for LOAEL to NOAEL extrapolations (unitless).
Wt = Average weight in kilograms (kg) for the representative species.
W = Average daily volume of water consumed in liters per day (L/d) by 
          the representative species.
FTLi = Average daily amount of food consumed from trophic 
          level i in kilograms per day (kg/d) by the representative 
          species.
BAF\WL\TLi = Bioaccumulation factor (BAF) for wildlife food 
          in trophic level i in liters per kilogram (L/kg), developed 
          using the BAF methodology in appendix B to part 132, 
          Methodology for Development of Bioaccumulation Factors. For 
          consumption of piscivorous birds by other birds (e.g., herring 
          gull by eagles), the BAF is derived by multiplying the trophic 
          level 3 BAF for fish by a biomagnification factor to account 
          for the biomagnification from fish to the consumed birds.
    B. Identification of Representative Species for Protection. For 
bioaccumulative chemicals, piscivorous species are identified as the 
focus of concern for wildlife criteria development in the Great Lakes. 
An analysis of known or estimated exposure components for avian and 
mammalian wildlife species is presented in the Wildlife TSD. This 
analysis identifies three avian species (eagle, kingfisher and herring 
gull) and two mammalian species (mink and otter) as representative 
species for protection. The TD obtained from toxicity data for each 
taxonomic class is used to calculate WVs for each of the five 
representative species.
    C. Calculation of Avian and Mammalian Wildlife Values and GLWC 
Derivation. The avian WV is the geometric mean of the WVs calculated for 
the three representative avian species. The mammalian WV is the 
geometric mean of the WVs calculated for the two representative 
mammalian species. The lower of the mammalian and avian WVs must be 
selected as the GLWC.

    III. Parameters of the Effect Component of the Wildlife Criteria 
                               Methodology

    A. Definitions. The following definitions provide additional 
specificity and guidance in the evaluation of toxicity data and the 
application of this methodology.
    Acceptable endpoints. For the purpose of wildlife criteria 
derivation, acceptable subchronic and chronic endpoints are those which 
affect reproductive or developmental

[[Page 654]]

success, organismal viability or growth, or any other endpoint which is, 
or is directly related to, parameters that influence population 
dynamics.
    Chronic effect. An adverse effect that is measured by assessing an 
acceptable endpoint, and results from continual exposure over several 
generations, or at least over a significant part of the test species' 
projected life span or life stage.
    Lowest-observed-adverse-effect-level (LOAEL). The lowest tested dose 
or concentration of a substance which resulted in an observed adverse 
effect in exposed test organisms when all higher doses or concentrations 
resulted in the same or more severe effects.
    No-observed-adverse-effect-level (NOAEL). The highest tested dose or 
concentration of a substance which resulted in no observed adverse 
effect in exposed test organisms where higher doses or concentrations 
resulted in an adverse effect.
    Subchronic effect. An adverse effect, measured by assessing an 
acceptable endpoint, resulting from continual exposure for a period of 
time less than that deemed necessary for a chronic test.
    B. Minimum Toxicity Database for Tier I Criteria Development. A TD 
value is required for criterion calculation. To derive a Tier I 
criterion for wildlife, the data set shall provide enough data to 
generate a subchronic or chronic dose-response curve for any given 
substance for both mammalian and avian species. In reviewing the 
toxicity data available which meet the minimum data requirements for 
each taxonomic class, the following order of preference shall be applied 
to select the appropriate TD to be used for calculation of individual 
WVs. Data from peer-reviewed field studies of wildlife species take 
precedence over other types of studies, where such studies are of 
adequate quality. An acceptable field study must be of subchronic or 
chronic duration, provide a defensible, chemical-specific dose-response 
curve in which cause and effect are clearly established, and assess 
acceptable endpoints as defined in this document. When acceptable 
wildlife field studies are not available, or determined to be of 
inadequate quality, the needed toxicity information may come from peer-
reviewed laboratory studies. When laboratory studies are used, 
preference shall be given to laboratory studies with wildlife species 
over traditional laboratory animals to reduce uncertainties in making 
interspecies extrapolations. All available laboratory data and field 
studies shall be reviewed to corroborate the final GLWC, to assess the 
reasonableness of the toxicity value used, and to assess the 
appropriateness of any UFs which are applied. When evaluating the 
studies from which a test dose is derived in general, the following 
requirements must be met:
    1. The mammalian data must come from at least one well-conducted 
study of 90 days or greater designed to observe subchronic or chronic 
effects as defined in this document.
    2. The avian data must come from at least one well-conducted study 
of 70 days or greater designed to observe subchronic or chronic effects 
as defined in this document.
    3. In reviewing the studies from which a TD is derived for use in 
calculating a WV, studies involving exposure routes other than oral may 
be considered only when an equivalent oral daily dose can be estimated 
and technically justified because the criteria calculations are based on 
an oral route of exposure.
    4. In assessing the studies which meet the minimum data 
requirements, preference should be given to studies which assess effects 
on developmental or reproductive endpoints because, in general, these 
are more important endpoints in ensuring that a population's 
productivity is maintained. The Wildlife TSD provides additional 
discussion on the selection of an appropriate toxicity study.
    C. Selection of TD Data. In selecting data to be used in the 
derivation of WVs, the evaluation of acceptable endpoints, as defined in 
Section III.A of this appendix, will be the primary selection criterion. 
All data not part of the selected subset may be used to assess the 
reasonableness of the toxicity value and the appropriateness of the Ufs 
which are applied.
    1. If more than one TD value is available within a taxonomic class, 
based on different endpoints of toxicity, that TD, which is likely to 
reflect best potential impacts to wildlife populations through resultant 
changes in mortality or fecundity rates, shall be used for the 
calculation of WVs.
    2. If more than one TD is available within a taxonomic class, based 
on the same endpoint of toxicity, the TD from the most sensitive species 
shall be used.
    3. If more than one TD based on the same endpoint of toxicity is 
available for a given species, the TD for that species shall be 
calculated using the geometric mean of those TDs.
    D. Exposure Assumptions in the Determination of the TD. 1. In those 
cases in which a TD is available in units other than milligrams of 
substance per kilograms per day (mg/kg/d), the following procedures 
shall be used to convert the TD to the appropriate units prior to 
calculating a WV.
    2. If the TD is given in milligrams of toxicant per liter of water 
consumed by the test animals (mg/L), the TD shall be multiplied by the 
daily average volume of water consumed by the test animals in liters per 
day (L/d) and divided by the average weight of the test animals in 
kilograms (kg).
    3. If the TD is given in milligrams of toxicant per kilogram of food 
consumed by the

[[Page 655]]

test animals (mg/kg), the TD shall be multiplied by the average amount 
of food in kilograms consumed daily by the test animals (kg/d) and 
divided by the average weight of the test animals in kilograms (kg).
    E. Drinking and Feeding Rates. 1. When drinking and feeding rates 
and body weight are needed to express the TD in milligrams of substance 
per kilograms per day (mg/kg/d), they are obtained from the study from 
which the TD was derived. If not already determined, body weight, and 
drinking and feeding rates are to be converted to a wet weight basis.
    2. If the study does not provide the needed values, the values shall 
be determined from appropriate scientific literature. For studies done 
with domestic laboratory animals, either the Registry of Toxic Effects 
of Chemical Substances (National Institute for Occupational Safety and 
Health, the latest edition, Cincinnati, OH), or Recommendations for and 
Documentation of Biological Values for Use in Risk Assessment (U.S. EPA, 
1988) should be consulted. When these references do not contain exposure 
information for the species used in a given study, either the allometric 
equations from Calder and Braun (1983) and Nagy (1987), which are 
presented below, or the exposure estimation methods presented in Chapter 
4 of the Wildlife Exposure Factors Handbook (U.S. EPA, 1993), should be 
applied to approximate the needed feeding or drinking rates. Additional 
discussion and recommendations are provided in the Wildlife TSD. The 
choice of the methods described above is at the discretion of the State 
or Tribe.
    3. For mammalian species, the general allometric equations are:

    a. F = 0.0687 x (Wt)\0.82\

Where:

F = Feeding rate of mammalian species in kilograms per day (kg/d) dry 
          weight.
Wt = Average weight in kilograms (kg) of the test animals.

    b. W = 0.099 x (Wt)\0.90\

Where:

W = Drinking rate of mammalian species in liters per day (L/d).
Wt = Average weight in kilograms (kg) of the test animals.

    4. For avian species, the general allometric equations are:

    a. F = 0.0582 (Wt)\0.65\

Where:

F = Feeding rate of avian species in kilograms per day (kg/d) dry 
          weight.
Wt = Average weight in kilograms (kg) of the test animals.

    b. W = 0.059 x (Wt)\0.67\

Where:

W = Drinking rate of avian species in liters per day (L/d).
Wt = Average weight in kilograms (kg) of the test animals.

    F. LOAEL to NOAEL Extrapolations (UFL). In those cases in 
which a NOAEL is unavailable as the TD and a LOAEL is available, the 
LOAEL may be used to estimate the NOAEL. If used, the LOAEL shall be 
divided by an UF to estimate a NOAEL for use in deriving WVs. The value 
of the UF shall not be less than one and should not exceed 10, depending 
on the dose-response curve and any other available data, and is 
represented by UFL in the equation expressed in Section II.A 
of this appendix. Guidance for selecting an appropriate UFL, 
based on a review of available wildlife toxicity data, is available in 
the Wildlife TSD.
    G. Subchronic to Chronic Extrapolations (USS). In 
instances where only subchronic data are available, the TD may be 
derived from subchronic data. In such cases, the TD shall be divided by 
an UF to extrapolate from subchronic to chronic levels. The value of the 
UF shall not be less than one and should not exceed 10, and is 
represented by UFS in the equation expressed in Section II.A 
of this appendix. This factor is to be used when assessing highly 
bioaccumulative substances where toxicokinetic considerations suggest 
that a bioassay of limited length underestimates chronic effects. 
Guidance for selecting an appropriate UFS, based on a review 
of available wildlife toxicity data, is available in the Wildlife TSD.
    H. Interspecies Extrapolations (UFA). 1. The selection of 
the UFA shall be based on the available toxicological data 
and on available data concerning the physicochemical, toxicokinetic, and 
toxicodynamic properties of the substance in question and the amount and 
quality of available data. This value is an UF that is intended to 
account for differences in toxicological sensitivity among species. 
Guidance for selecting an appropriate UFA, based on a review 
of available wildlife toxicity data, is available in the Wildlife TSD. 
Additional discussion of an interspecies UF located in appendix A to the 
Great Lakes Water Quality Initiative Technical Support Document for 
Human Health Criteria may be useful in determining the appropriate value 
for UFA.
    2. For the derivation of Tier I criteria, a UFA shall not 
be less than one and should not exceed 100, and shall be applied to each 
of the five representative species, based on existing data and best 
professional judgment. The value of UFA may differ for each 
of the representative species.
    3. For Tier I wildlife criteria, the UFA shall be used 
only for extrapolating toxicity data across species within a taxonomic 
class, except as provided below. The Tier I UFA is not 
intended for interclass extrapolations because of the poorly defined 
comparative toxicokinetic and toxicodynamic parameters between mammals 
and birds. However, an

[[Page 656]]

interclass extrapolation employing a UFA may be used for a 
given chemical if it can be supported by a validated biologically-based 
dose-response model or by an analysis of interclass toxicological data, 
considering acceptable endpoints, for a chemical analog that acts under 
the same mode of toxic action.

   IV. Parameters of the Exposure Component of the Wildlife Criteria 
                               Methodology

    A. Drinking and Feeding Rates of Representative Species. The body 
weights (Wt), feeding rates (FTli), drinking rates (W), and 
trophic level dietary composition (as food ingestion rate and percent in 
diet) for each of the five representative species are presented in Table 
D-2 of this appendix. Guidance on incorporating the non-aquatic portion 
of the bald eagle and mink diets in the criteria calculations is 
available in the Wildlife TSD.
    B. BAFs. The Methodology for Development of Bioaccumulation Factors 
is presented in appendix B to part 132. Trophic level 3 and 4 BAFs are 
used to derive Wvs because these are the trophic levels at which the 
representative species feed.

   Sec. Appendix E to Part 132--Great Lakes Water Quality Initiative 
                         Antidegradation Policy

    Great Lakes States and Tribes shall adopt provisions consistent with 
(as protective as) appendix E to part 132.
    The State or Tribe shall adopt an antidegradation standard 
applicable to all waters of the Great Lakes System and identify the 
methods for implementing such a standard. Consistent with 40 CFR 131.12, 
an acceptable antidegradation standard and implementation procedure are 
required elements of a State's or Tribe's water quality standards 
program. Consistent with 40 CFR 131.6, a complete water quality 
standards submission needs to include both an antidegradation standard 
and antidegradation implementation procedures. At a minimum, States and 
Tribes shall adopt provisions in their antidegradation standard and 
implementation methods consistent with sections I, II, III and IV of 
this appendix, applicable to pollutants identified as bioaccumulative 
chemicals of concern (BCCs).

                       I. Antidegradation Standard

    This antidegradation standard shall be applicable to any action or 
activity by any source, point or nonpoint, of pollutants that is 
anticipated to result in an increased loading of BCCs to surface waters 
of the Great Lakes System and for which independent regulatory authority 
exists requiring compliance with water quality standards. Pursuant to 
this standard:
    A. Existing instream water uses, as defined pursuant to 40 CFR 131, 
and the level of water quality necessary to protect existing uses shall 
be maintained and protected. Where designated uses of the waterbody are 
impaired, there shall be no lowering of the water quality with respect 
to the pollutant or pollutants which are causing the impairment;
    B. Where, for any parameter, the quality of the waters exceed levels 
necessary to support the propagation of fish, shellfish, and wildlife 
and recreation in and on the waters, that water shall be considered high 
quality for that parameter consistent with the definition of high 
quality water found at section II.A of this appendix and that quality 
shall be maintained and protected unless the State or Tribe finds, after 
full satisfaction of intergovernmental coordination and public 
participation provisions of the State's or Tribe's continuing planning 
process, that allowing lower water quality is necessary to accommodate 
important economic or social development in the area in which the waters 
are located. In allowing such degradation, the State or Tribe shall 
assure water quality adequate to protect existing uses fully. Further, 
the State or Tribe shall assure that there shall be achieved the highest 
statutory and regulatory requirements for all new and existing point 
sources and all cost-effective and reasonable best management practices 
for nonpoint source control. The State or Tribe shall utilize the 
Antidegradation Implementation Procedures adopted pursuant to the 
requirements of this regulation in determining if any lowering of water 
quality will be allowed;
    C. Where high quality waters constitute an outstanding national 
resource, such as waters of national and State parks and wildlife 
refuges and waters of exceptional recreational or ecological 
significance, that water quality shall be maintained and protected; and
    D. In those cases where the potential lowering of water quality is 
associated with a thermal discharge, the decision to allow such 
degradation shall be consistent with section 316 of the Clean Water Act 
(CWA).

              II. Antidegradation Implementation Procedures

    A. Definitions.
    Control Document. Any authorization issued by a State, Tribal or 
Federal agency to any source of pollutants to waters under its 
jurisdiction that specifies conditions under which the source is allowed 
to operate.
    High quality waters. High quality waters are water bodies in which, 
on a parameter by parameter basis, the quality of the waters exceeds 
levels necessary to support propagation of fish, shellfish, and wildlife 
and recreation in and on the water.
    Lake Superior Basin--Outstanding International Resource Waters. 
Those waters designated as such by a Tribe or State consistent with the 
September 1991 Bi-National Program to Restore and Protect the Lake 
Superior Basin. The purpose of such designations shall be to ensure that 
any new or increased discharges of Lake Superior bioaccumulative 
substances of immediate concern are subject to best technology in 
process and treatment requirements.
    Lake Superior Basin--Outstanding National Resource Waters. Those 
waters designated as such by a Tribe or State consistent with the 
September 1991 Bi-National Program to Restore and Protect the Lake 
Superior Basin. The purpose of such designations shall be to prohibit 
new or increased discharges of Lake Superior bioaccumulative substances 
of immediate concern from point sources in these areas.
    Lake Superior bioaccumulative substances of immediate concern. A 
list of substances identified in the September 1991 Bi-National Program 
to Restore and Protect the Lake Superior Basin. They include: 2, 3, 7, 
8-TCDD; octachlorostyrene; hexachlorobenzene; chlordane; DDT, DDE, and 
other metabolites; toxaphene; PCBs; and mercury. Other

[[Page 658]]

chemicals may be added to the list following States' or Tribes' 
assessments of environmental effects and impacts and after public review 
and comment.
    Outstanding National Resource Waters. Those waters designated as 
such by a Tribe or State. The State or Tribal designation shall describe 
the quality of such waters to serve as the benchmark of the water 
quality that shall be maintained and protected. Waters that may be 
considered for designation as Outstanding National Resource Waters 
include, but are not limited to, water bodies that are recognized as:
    Important because of protection through official action, such as 
Federal or State law, Presidential or secretarial action, international 
treaty, or interstate compact;
    Having exceptional recreational significance;
    Having exceptional ecological significance;
    Having other special environmental, recreational, or ecological 
attributes; or waters whose designation as Outstanding National Resource 
Waters is reasonably necessary for the protection of other waters so 
designated.
    Significant Lowering of Water Quality. A significant lowering of 
water quality occurs when there is a new or increased loading of any BCC 
from any regulated existing or new facility, either point source or 
nonpoint source for which there is a control document or reviewable 
action, as a result of any activity including, but not limited to:
    (1) Construction of a new regulated facility or modification of an 
existing regulated facility such that a new or modified control document 
is required;
    (2) Modification of an existing regulated facility operating under a 
current control document such that the production capacity of the 
facility is increased;
    (3) Addition of a new source of untreated or pretreated effluent 
containing or expected to contain any BCC to an existing wastewater 
treatment works, whether public or private;
    (4) A request for an increased limit in an applicable control 
document;
    (5) Other deliberate activities that, based on the information 
available, could be reasonably expected to result in an increased 
loading of any BCC to any waters of the Great Lakes System.
    b. Notwithstanding the above, changes in loadings of any BCC within 
the existing capacity and processes, and that are covered by the 
existing applicable control document, are not subject to an 
antidegradation review. These changes include, but are not limited to:
    (1) Normal operational variability;
    (2) Changes in intake water pollutants;
    (3) Increasing the production hours of the facility, (e.g., adding a 
second shift); or
    (4) Increasing the rate of production.
    C. Also, excluded from an antidegradation review are new effluent 
limits based on improved monitoring data or new water quality criteria 
or values that are not a result of changes in pollutant loading.
    B. For all waters, the Director shall ensure that the level of water 
quality necessary to protect existing uses is maintained. In order to 
achieve this requirement, and consistent with 40 CFR 131.10, water 
quality standards use designations must include all existing uses. 
Controls shall be established as necessary on point and nonpoint sources 
of pollutants to ensure that the criteria applicable to the designated 
use are achieved in the water and that any designated use of a 
downstream water is protected. Where water quality does not support the 
designated uses of a waterbody or ambient pollutant concentrations 
exceed water quality criteria applicable to that waterbody, the Director 
shall not allow a lowering of water quality for the pollutant or 
pollutants preventing the attainment of such uses or exceeding such 
criteria.
    C. For Outstanding National Resource Waters:
    1. The Director shall ensure, through the application of appropriate 
controls on pollutant sources, that water quality is maintained and 
protected.
    2. Exception. A short-term, temporary (i.e., weeks or months) 
lowering of water quality may be permitted by the Director.
    D. For high quality waters, the Director shall ensure that no action 
resulting in a lowering of water quality occurs unless an 
antidegradation demonstration has been completed pursuant to section III 
of this appendix and the information thus provided is determined by the 
Director pursuant to section IV of this appendix to adequately support 
the lowering of water quality.
    1. The Director shall establish conditions in the control document 
applicable to the regulated facility that prohibit the regulated 
facility from undertaking any deliberate action, such that there would 
be an increase in the rate of mass loading of any BCC, unless an 
antidegradation demonstration is provided to the Director and approved 
pursuant to section IV of this appendix prior to commencement of the 
action. Imposition of limits due to improved monitoring data or new 
water quality criteria or values, or changes in loadings of any BCC 
within the existing capacity and processes, and that are covered by the 
existing applicable control document, are not subject to an 
antidegradation review.
    2. For BCCs known or believed to be present in a discharge, from a 
point or nonpoint source, a monitoring requirement shall be included in 
the control document. The control document shall also include a 
provision requiring the source to notify the Director or any increased 
loadings. Upon notification, the Director shall require actions as 
necessary to reduce or eliminate the increased loading.

[[Page 659]]

    3. Fact Sheets prepared pursuant to 40 CFR 124.8 and 124.56 shall 
reflect any conditions developed under sections II.D.1 or II.D.2 of this 
appendix and included in a permit.
    E. Special Provisions for Lake Superior. The following conditions 
apply in addition to those specified in section II.B through II.C of 
this appendix for waters of Lake Superior so designated.
    1. A State or Tribe may designate certain specified areas of the 
Lake Superior Basin as Lake Superior Basin--Outstanding National 
Resource Waters for the purpose of prohibiting the new or increased 
discharge of Lake Superior bioaccumulative substances of immediate 
concern from point sources in these areas.
    2. States and Tribes may designate all waters of the Lake Superior 
Basin as Outstanding International Resource Waters for the purpose of 
restricting the increased discharge of Lake Superior bioaccumulative 
substances of immediate concern from point sources consistent with the 
requirements of sections III.C and IV.B of this appendix.
    F. Exemptions. Except as the Director may determine on a case-by-
case basis that the application of these procedures is required to 
adequately protect water quality, or as the affected waterbody is an 
Outstanding National Resource Water as defined in section II.A of this 
appendix, the procedures in this part do not apply to:
    1. Short-term, temporary (i.e., weeks or months) lowering of water 
quality;
    2. Bypasses that are not prohibited at 40 CFR 122.41(m); and
    3. Response actions pursuant to the Comprehensive Environmental 
Response, Compensation and Liability Act (CERCLA), as amended, or 
similar Federal, State or Tribal authorities, undertaken to alleviate a 
release into the environment of hazardous substances, pollutants or 
contaminants which may pose an imminent and substantial danger to public 
health or welfare.

                   III. Antidegradation Demonstration

    Any entity seeking to lower water quality in a high quality water or 
create a new or increased discharge of Lake Superior bioaccumulative 
substances of immediate concern in a Lake Superior Outstanding 
International Resource Water must first, as required by sections II.D or 
II.E.2 of this appendix, submit an antidegradation demonstration for 
consideration by the Director. States and Tribes should tailor the level 
of detail and documentation in antidegradation reviews, to the specific 
circumstances encountered. The antidegradation demonstration shall 
include the following:
    A. Pollution Prevention Alternatives Analysis. Identify any cost-
effective pollution prevention alternatives and techniques that are 
available to the entity, that would eliminate or significantly reduce 
the extent to which the increased loading results in a lowering of water 
quality.
    B. Alternative or Enhanced Treatment Analysis. Identify alternative 
or enhanced treatment techniques that are available to the entity that 
would eliminate the lowering of water quality and their costs relative 
to the cost of treatment necessary to achieve applicable effluent 
limitations.
    C. Lake Superior. If the States or Tribes designate the waters of 
Lake Superior as Outstanding International Resource Waters pursuant to 
section II.E.2 of this appendix, then any entity proposing a new or 
increased discharge of any Lake Superior bioaccumulative substance of 
immediate concern to the Lake Superior Basin shall identify the best 
technology in process and treatment to eliminate or reduce the extent of 
the lowering of water quality. In this case, the requirements in section 
III.B of this appendix do not apply.
    D. Important Social or Economic Development Analysis. Identify the 
social or economic development and the benefits to the area in which the 
waters are located that will be foregone if the lowering of water 
quality is not allowed.
    E. Special Provision for Remedial Actions. Entities proposing 
remedial actions pursuant to the CERCLA, as amended, corrective actions 
pursuant to the Resource Conservation and Recovery Act, as amended, or 
similar actions pursuant to other Federal or State environmental 
statutes may submit information to the Director that demonstrates that 
the action utilizes the most cost effective pollution prevention and 
treatment techniques available, and minimizes the necessary lowering of 
water quality, in lieu of the information required by sections III.B 
through III.D of this appendix.

                      IV. Antidegradation Decision

    A. Once the Director determines that the information provided by the 
entity proposing to increase loadings is administratively complete, the 
Director shall use that information to determine whether or not the 
lowering of water quality is necessary, and, if it is necessary, whether 
or not the lowering of water quality will support important social and 
economic development in the area. If the proposed lowering of water 
quality is either not necessary, or will not support important social 
and economic development, the Director shall deny the request to lower 
water quality. If the lowering of water quality is necessary, and will 
support important social and economic development, the Director may 
allow all or part of the proposed lowering to occur as necessary to 
accommodate the important social and economic development. In no event 
may the decision reached under this section allow water quality to be 
lowered below the minimum level required to fully support existing and 
designated uses.

[[Page 660]]

The decision of the Director shall be subject to the public 
participation requirements of 40 CFR 25.
    B. If States designate the waters of Lake Superior as Outstanding 
International Resource Waters pursuant to section II.E.2 of this 
appendix, any entity requesting to lower water quality in the Lake 
Superior Basin as a result of the new or increased discharge of any Lake 
Superior bioaccumulative substance of immediate concern shall be 
required to install and utilize the best technology in process and 
treatment as identified by the Director.



   Sec. Appendix F to Part 132--Great Lakes Water Quality Initiative 
                        Implementation Procedures

     Procedure 1: Site-specific Modifications to Criteria and Values

    Great Lakes States and Tribes shall adopt provisions consistent with 
(as protective as) this procedure.
    A. Requirements for Site-specific Modifications to Criteria and 
Values. Criteria and values may be modified on a site-specific basis to 
reflect local environmental conditions as restricted by the following 
provisions. Any such modifications must be protective of designated uses 
and aquatic life, wildlife or human health and be submitted to EPA for 
approval. In addition, any site-specific modifications that result in 
less stringent criteria must be based on a sound scientific rationale 
and shall not be likely to jeopardize the continued existence of 
endangered or threatened species listed or proposed under section 4 of 
the Endangered Species Act (ESA) or result in the destruction or adverse 
modification of such species' critical habitat. More stringent 
modifications shall be developed to protect endangered or threatened 
species listed or proposed under section 4 of the ESA, where such 
modifications are necessary to ensure that water quality is not likely 
to jeopardize the continued existence of such species or result in the 
destruction or adverse modification of such species' critical habitat. 
More stringent modifications may also be developed to protect candidate 
(C1) species being considered by the U.S. Fish and Wildlife Service 
(FWS) for listing under section 4 of the ESA, where such modifications 
are necessary to protect such species.
    1. Aquatic Life.
    a. Aquatic life criteria or values may be modified on a site-
specific basis to provide an additional level of protection, pursuant to 
authority reserved to the States and Tribes under Clean Water Act (CWA) 
section 510.
    Guidance on developing site-specific criteria in these instances is 
provided in Chapter 3 of the U.S. EPA Water Quality Standards Handbook, 
Second Edition--Revised (1994).
    b. Less stringent site-specific modifications to chronic or acute 
aquatic life criteria or values may be developed when:
    i. The local water quality characteristics such as Ph, hardness, 
temperature, color, etc., alter the biological availability or toxicity 
of a pollutant; or
    ii. The sensitivity of the aquatic organisms species that ``occur at 
the site'' differs from the species actually tested in developing the 
criteria. The phrase ``occur at the site'' includes the species, genera, 
families, orders, classes, and phyla that: are usually present at the 
site; are present at the site only seasonally due to migration; are 
present intermittently because they periodically return to or extend 
their ranges into the site; were present at the site in the past, are 
not currently present at the site due to degraded conditions, and are 
expected to return to the site when conditions improve; are present in 
nearby bodies of water, are not currently present at the site due to 
degraded conditions, and are expected to be present at the site when 
conditions improve. The taxa that ``occur at the site'' cannot be 
determined merely by sampling downstream and/or upstream of the site at 
one point in time. ``Occur at the site'' does not include taxa that were 
once present at the site but cannot exist at the site now due to 
permanent physical alteration of the habitat at the site resulting, for 
example, from dams, etc.
    c. Less stringent modifications also may be developed to acute and 
chronic aquatic life criteria or values to reflect local physical and 
hydrological conditions.
    Guidance on developing site-specific criteria is provided in Chapter 
3 of the U.S. EPA Water Quality Standards Handbook, Second Edition--
Revised (1994).
    d. Any modifications to protect threatened or endangered aquatic 
species required by procedure 1.A of this appendix may be accomplished 
using either of the two following procedures:
    i. If the Species Mean Acute Value (SMAV) for a listed or proposed 
species, or for a surrogate of such species, is lower than the 
calculated Final Acute Value (FAV), such lower SMAV may be used instead 
of the calculated FAV in developing site-specific modified criteria; or,
    ii. The site-specific criteria may be calculated using the 
recalculation procedure for site-specific modifications described in 
Chapter 3 of the U.S. EPA Water Quality Standards Handbook, Second 
Edition--Revised (1994).
    2. Wildlife.
    a. Wildlife water quality criteria may be modified on a site-
specific basis to provide an additional level of protection, pursuant to 
authority reserved to the States and Tribes under CWA section 510.
    b. Less stringent site-specific modifications to wildlife water 
quality criteria may

[[Page 661]]

be developed when a site-specific bioaccumulation factor (BAF) is 
derived which is lower than the system-wide BAF derived under appendix B 
of this part. The modification must consider both the mobility of prey 
organisms and wildlife populations in defining the site for which 
criteria are developed. In addition, there must be a showing that:
    i. Any increased uptake of the toxicant by prey species utilizing 
the site will not cause adverse effects in wildlife populations; and
    ii. Wildlife populations utilizing the site or downstream waters 
will continue to be fully protected.
    c. Any modification to protect endangered or threatened wildlife 
species required by procedure 1.A of this appendix must consider both 
the mobility of prey organisms and wildlife populations in defining the 
site for which criteria are developed, and may be accomplished by using 
the following recommended method.
    i. The methodology presented in appendix D to part 132 is used, 
substituting appropriate species-specific toxicological, 
epidemiological, or exposure information, including changes to the BAF;
    ii. An interspecies uncertainty factor of 1 should be used where 
epidemiological data are available for the species in question. If 
necessary, species-specific exposure parameters can be derived as 
presented in appendix D of this part;
    iii. An intraspecies uncertainty factor (to account for protection 
of individuals within a wildlife population) should be applied in the 
denominator of the effect part of the wildlife equation in appendix D of 
this part in a manner consistent with the other uncertainty factors 
described in appendix D of this part; and
    iv. The resulting wildlife value for the species in question should 
be compared to the two class-specific wildlife values which were 
previously calculated, and the lowest of the three shall be selected as 
the site-specific modification.
    Note: Further discussion on the use of this methodology may be found 
in the Great Lakes Water Quality Initiative Technical Support Document 
for Wildlife Criteria.
    3. BAFs.
    a. BAFs may be modified on a site-specific basis to larger values, 
pursuant to the authority reserved to the States and Tribes under CWA 
section 510, where reliable data show that local bioaccumulation is 
greater than the system-wide value.
    b. BAFs may be modified on a site-specific basis to lower values, 
where scientifically defensible, if:
    i. The fraction of the total chemical that is freely dissolved in 
the ambient water is different than that used to derive the system-wide 
BAFs (i.e., the concentrations of particulate organic carbon and the 
dissolved organic carbon are different than those used to derive the 
system-wide BAFs);
    ii. Input parameters of the Gobas model, such as the structure of 
the aquatic food web and the disequilibrium constant, are different at 
the site than those used to derive the system-wide BAFs;
    iii. The percent lipid of aquatic organisms that are consumed and 
occur at the site is different than that used to derive the system-wide 
BAFs; or
    iv. Site-specific field-measured BAFs or biota-sediment accumulation 
factor (BSAFs) are determined.
    If site-specific BAFs are derived, they shall be derived using the 
methodology in appendix B of this part.
    c. Any more stringent modifications to protect threatened or 
endangered species required by procedure 1.A of this appendix shall be 
derived using procedures set forth in the methodology in appendix B of 
this part.
    4. Human Health.
    a. Human health criteria or values may be modified on a site-
specific basis to provide an additional level of protection, pursuant to 
authority reserved to the States and Tribes under CWA section 510. Human 
health criteria or values shall be modified on a site-specific basis to 
provide additional protection appropriate for highly exposed 
subpopulations.
    b. Less stringent site-specific modifications to human health 
criteria or values may be developed when:
    i. local fish consumption rates are lower than the rate used in 
deriving human health criteria or values under appendix C of this part; 
and/or
    ii. a site-specific BAF is derived which is lower than that used in 
deriving human health criteria or values under appendix C of this part.
    B. Notification Requirements. When a State proposes a site-specific 
modification to a criterion or value as allowed in section 4.A above, 
the State should notify the other Great Lakes States of such a proposal 
and, for less stringent criteria, supply appropriate justification.
    C. References.

  Procedure 2: Variances from Water Quality Standards for Point Sources

    The Great Lakes States or Tribes may adopt water quality standards 
(WQS) variance procedures and may grant WQS variances for point sources 
pursuant to such procedures. Variance procedures shall be consistent 
with (as protective as) the provisions in this procedure.

[[Page 662]]

    A. Applicability. A State or Tribe may grant a variance to a WQS 
which is the basis of a water quality-based effluent limitation included 
in a National Pollutant Discharge Elimination System (NPDES) permit. A 
WQS variance applies only to the permittee requesting the variance and 
only to the pollutant or pollutants specified in the variance. A 
variance does not affect, or require the State or Tribe to modify, the 
corresponding water quality standard for the waterbody as a whole.
    1. This provision shall not apply to new Great Lakes dischargers or 
recommencing dischargers.
    2. A variance to a water quality standard shall not be granted that 
would likely jeopardize the continued existence of any endangered or 
threatened species listed under Section 4 of the Endangered Species Act 
(ESA) or result in the destruction or adverse modification of such 
species' critical habitat.
    3. A WQS variance shall not be granted if standards will be attained 
by implementing effluent limits required under sections 301(b) and 306 
of the Clean Water Act (CWA) and by the permittee implementing cost-
effective and reasonable best management practices for nonpoint source 
control.
    B. Maximum Timeframe for Variances. A WQS variance shall not exceed 
five years or the term of the NPDES permit, whichever is less. A State 
or Tribe shall review, and modify as necessary, WQS variances as part of 
each water quality standards review pursuant to section 303(c) of the 
CWA.
    C. Conditions to Grant a Variance. A variance may be granted if:
    1. The permittee demonstrates to the State or Tribe that attaining 
the WQS is not feasible because:
    a. Naturally occurring pollutant concentrations prevent the 
attainment of the WQS;
    b. Natural, ephemeral, intermittent or low flow conditions or water 
levels prevent the attainment of the WQS, unless these conditions may be 
compensated for by the discharge of sufficient volume of effluent to 
enable WQS to be met without violating State or Tribal water 
conservation requirements;
    c. Human-caused conditions or sources of pollution prevent the 
attainment of the WQS and cannot be remedied, or would cause more 
environmental damage to correct than to leave in place;
    d. Dams, diversions or other types of hydrologic modifications 
preclude the attainment of the WQS, and it is not feasible to restore 
the waterbody to its original condition or to operate such modification 
in a way that would result in the attainment of the WQS;
    e. Physical conditions related to the natural features of the 
waterbody, such as the lack of a proper substrate cover, flow, depth, 
pools, riffles, and the like, unrelated to chemical water quality, 
preclude attainment of WQS; or
    f. Controls more stringent than those required by sections 301(b) 
and 306 of the CWA would result in substantial and widespread economic 
and social impact.
    2. In addition to the requirements of C.1, above, the permittee 
shall also:
    a. Show that the variance requested conforms to the requirements of 
the State's or Tribe's antidegradation procedures; and
    b. Characterize the extent of any increased risk to human health and 
the environment associated with granting the variance compared with 
compliance with WQS absent the variance, such that the State or Tribe is 
able to conclude that any such increased risk is consistent with the 
protection of the public health, safety and welfare.
    D. Submittal of Variance Application. The permittee shall submit an 
application for a variance to the regulatory authority issuing the 
permit. The application shall include:
    1. All relevant information demonstrating that attaining the WQS is 
not feasible based on one or more of the conditions in section C.1 of 
this procedure; and,
    2. All relevant information demonstrating compliance with the 
conditions in section C.2 of this procedure.
    E. Public Notice of Preliminary Decision. Upon receipt of a complete 
application for a variance, and upon making a preliminary decision 
regarding the variance, the State or Tribe shall public notice the 
request and preliminary decision for public comment pursuant to the 
regulatory authority's Administrative Procedures Act and shall notify 
the other Great Lakes States and Tribes of the preliminary decision. 
This public notice requirement may be satisfied by including the 
supporting information for the variance and the preliminary decision in 
the public notice of a draft NPDES permit.
    F. Final Decision on Variance Request. The State or Tribe shall 
issue a final decision on the variance request within 90 days of the 
expiration of the public comment period required in section E of this 
procedure. If all or part of the variance is approved by the State or 
Tribe, the decision shall include all permit conditions needed to 
implement those parts of the variance so approved. Such permit 
conditions shall, at a minimum, require:
    1. Compliance with an initial effluent limitation which, at the time 
the variance is granted, represents the level currently achievable by 
the permittee, and which is no less stringent than that achieved under 
the previous permit;
    2. That reasonable progress be made toward attaining the water 
quality standards for the waterbody as a whole through appropriate 
conditions;
    3. When the duration of a variance is shorter than the duration of a 
permit, compliance with an effluent limitation sufficient to

[[Page 663]]

meet the underlying water quality standard, upon the expiration of said 
variance; and
    4. A provision that allows the permitting authority to reopen and 
modify the permit based on any State or Tribal triennial water quality 
standards revisions to the variance.
    The State shall deny a variance request if the permittee fails to 
make the demonstrations required under section C of this procedure.
    G. Incorporating Variance into Permit. The State or Tribe shall 
establish and incorporate into the permittee's NPDES permit all 
conditions needed to implement the variance as determined in section F 
of this procedure.
    H. Renewal of Variance. A variance may be renewed, subject to the 
requirements of sections A through G of this procedure. As part of any 
renewal application, the permittee shall again demonstrate that 
attaining WQS is not feasible based on the requirements of section C of 
this procedure. The permittee's application shall also contain 
information concerning its compliance with the conditions incorporated 
into its permit as part of the original variance pursuant to sections F 
and G of this procedure. Renewal of a variance may be denied if the 
permittee did not comply with the conditions of the original variance.
    I. EPA Approval. All variances and supporting information shall be 
submitted by the State or Tribe to the appropriate EPA regional office 
and shall include:
    1. Relevant permittee applications pursuant to section D of this 
procedure;
    2. Public comments and records of any public hearings pursuant to 
section E of this procedure;
    3. The final decision pursuant to section F of this procedure; and,
    4. NPDES permits issued pursuant to section G of this procedure.
    5. Items required by sections I.1 through I.3. of this procedure 
shall be submitted by the State within 30 days of the date of the final 
variance decision. The item required by section I.4 of this procedure 
shall be submitted in accordance with the State or Tribe Memorandum of 
Agreement with the Regional Administrator pursuant to 40 CFR 123.24.
    6. EPA shall review the State or Tribe submittal for compliance with 
the CWA pursuant to 40 CFR 123.44, and 40 CFR 131.21.
    J. State WQS Revisions. All variances shall be appended to the State 
or Tribe WQS rules.

Procedure 3: Total Maximum Daily Loads, Wasteload Allocations for Point 
Sources, Load Allocations for Nonpoint Sources, Wasteload Allocations in 
    the Absence of a TMDL, and Preliminary Wasteload Allocations for 
Purposes of Determining the Need for Water Quality Based Effluent Limits

    The Great Lakes States and Tribes shall adopt provisions consistent 
with (as protective as) this procedure 3 for the purpose of developing 
Total Maximum Daily Loads (TMDLs), Wasteload Allocations (WLAs) in the 
Absence of TMDLs, and Preliminary Wasteload Allocations for Purposes of 
Determining the Need for Water Quality Based Effluent Limits (WQBELs), 
except as specifically provided.
    A. Where a State or Tribe develops an assessment and remediation 
plan that the State or Tribe certifies meets the requirements of 
sections B through F of this procedure and public participation 
requirements applicable to TMDLs, and that has been approved by EPA as 
meeting those requirements under 40 CFR 130.6, the assessment and 
remediation plan may be used in lieu of a TMDL for purposes of appendix 
F to part 132. Assessment and remediation plans under this procedure may 
include, but are not limited to, Lakewide Management Plans, Remedial 
Action Plans, and State Water Quality Management Plans. Also, any part 
of an assessment and remediation plan that also satisfies one or more 
requirements under Clean Water Act (CWA) section 303(d) or implementing 
regulations may be incorporated by reference into a TMDL as appropriate. 
Assessment and remediation plans under this section should be tailored 
to the level of detail and magnitude for the watershed and pollutant 
being assessed.
    B. General Conditions of Application. Except as provided in Sec. 
132.4, the following are conditions applicable to establishing TMDLs for 
all pollutants and pollutant parameters in the Great Lakes System, with 
the exception of whole effluent toxicity, unless otherwise provided in 
procedure 6 of appendix F. Where specified, these conditions also apply 
to wasteload allocations (WLAs) calculated in the absence of TMDLs and 
to preliminary WLAs for purposes of determining the needs for WQBELs 
under procedure 5 of appendix F.
    1. TMDLs Required. TMDLs shall, at a minimum, be established in 
accordance with the listing and priority setting process established in 
section 303(d) of the CWA and at 40 CFR 130.7. Where water quality 
standards cannot be attained immediately, TMDLs must reflect reasonable 
assurances that water quality standards will be attained in a reasonable 
period of time. Some TMDLs may

[[Page 664]]

be based on attaining water quality standards over a period of time, 
with specific controls on individual sources being implemented in 
stages. Determining the reasonable period of time in which water quality 
standards will be met is a case-specific determination considering a 
number of factors including, but not limited to: receiving water 
characteristics; persistence, behavior and ubiquity of pollutants of 
concern; type of remediation activities necessary; available regulatory 
and non-regulatory controls; and individual State or Tribal requirements 
for attainment of water quality standards.
    2. Attainment of Water Quality Standards. A TMDL must ensure 
attainment of applicable water quality standards, including all numeric 
and narrative criteria, Tier I criteria, and Tier II values for each 
pollutant or pollutants for which a TMDL is established.
    3. TMDL Allocations.
    a. TMDLs shall include WLAs for point sources and load allocations 
(LAs) for nonpoint sources, including natural background, such that the 
sum of these allocations is not greater than the loading capacity of the 
water for the pollutant(s) addressed by the TMDL, minus the sum of a 
specified margin of safety (MOS) and any capacity reserved for future 
growth.
    b. Nonpoint source LAs shall be based on:
    i. Existing pollutant loadings if changes in loadings are not 
reasonably anticipated to occur;
    ii. Increases in pollutant loadings that are reasonably anticipated 
to occur;
    iii. Anticipated decreases in pollutant loadings if such decreased 
loadings are technically feasible and are reasonably anticipated to 
occur within a reasonable time period as a result of implementation of 
best management practices or other load reduction measures. In 
determining whether anticipated decreases in pollutant loadings are 
technically feasible and can reasonably be expected to occur within a 
reasonable period of time, technical and institutional factors shall be 
considered. These decisions are case-specific and should reflect the 
particular TMDL under consideration.
    c. WLAs. The portion of the loading capacity not assigned to 
nonpoint sources including background, or to an MOS, or reserved for 
future growth is allocated to point sources. Upon reissuance, NPDES 
permits for these point sources must include effluent limitations 
consistent with WLAs in EPA-approved or EPA-established TMDLs.
    d. Monitoring. For LAs established on the basis of subsection b.iii 
above, monitoring data shall be collected and analyzed in order to 
validate the TMDL's assumptions, to varify anticipated load reductions, 
to evaluate the effectiveness of controls being used to implement the 
TMDL, and to revise the WLAs and LAs as necessary to ensure that water 
quality standards will be achieved within the time-period established in 
the TMDL.
    4. WLA Values. If separate EPA-approved or EPA-established TMDLs are 
prepared for different segments of the same watershed, and the separate 
TMDLs each include WLAs for the same pollutant for one or more of the 
same point sources, then WQBELs for that pollutant for the point 
source(s) shall be consistent with the most stringent of those WLAs in 
order to ensure attainment of all applicable water quality standards.
    5. Margin of Safety (MOS). Each TMDL shall include a MOS sufficient 
to account for technical uncertainties in establishing the TMDL and 
shall describe the manner in which the MOS is determined and 
incorporated into the TMDL. The MOS may be provided by leaving a portion 
of the loading capacity unallocated or by using conservative modeling 
assumptions to establish WLAs and LAs. If a portion of the loading 
capacity is left unallocated to provide a MOS, the amount left 
unallocated shall be described. If conservative modeling assumptions are 
relied on to provide a MOS, the specific assumptions providing the MOS 
shall be identified.
    6. More Stringent Requirements. States and Tribes may exercise 
authority reserved to them under section 510 of the CWA to develop more 
stringent TMDLs (including WLAs and LAs) than are required herein, 
provided that all LAs in such TMDLs reflect actual nonpoint source loads 
or those loads that can reasonably be expected to occur within a 
reasonable time-period as a result of implementing nonpoint source 
controls.
    7. Accumulation in Sediments. TMDLs shall reflect, where appropriate 
and where sufficient data are available, contributions to the water 
column from sediments inside and outside of any applicable mixing zones. 
TMDLs shall be sufficiently stringent so as to prevent accumulation of 
the pollutant of concern in sediments to levels injurious to designated 
or existing uses, human health, wildlife and aquatic life.
    8. Wet Weather Events. Notwithstanding the exception provided for 
the establishment of controls on wet weather point sources in Sec. 
132.4(e)(1), TMDLs shall reflect, where appropriate and where sufficient 
data are available, discharges resulting from wet weather events. This 
procedure does not provide specific procedures for considering 
discharges resulting from wet weather events. However, some of the 
provisions of procedure 3 may be deemed appropriate for considering wet 
weather events on a case-by-case basis.
    9. Background Concentration of Pollutants. The representative 
background concentration of pollutants shall be established in 
accordance with this subsection to develop TMDLs, WLAs calculated in the 
absence of a TMDL, or preliminary WLAs for purposes of

[[Page 665]]

determining the need for WQBELs under procedure 5 of appendix F. 
Background loadings may be accounted for in a TMDL through an allocation 
to a single ``background'' category or through individual allocations to 
the various background sources.
    a. Definition of Background. ``Background'' represents all loadings 
that: (1) flow from upstream waters into the specified watershed, 
waterbody or waterbody segment for which a TMDL, WLA in the absence of a 
TMDL or preliminary WLA for the purpose of determining the need for a 
WQBEL is being developed; (2) enter the specified watershed, waterbody 
or waterbody segment through atmospheric deposition or sediment release 
or resuspension; or (3) occur within the watershed, waterbody or 
waterbody segment as a result of chemical reactions.
    b. Data considerations. When determining what available data are 
acceptable for use in calculating background, the State or Tribe should 
use best professional judgment, including consideration of the sampling 
location and the reliability of the data through comparison to reported 
analytical detection levels and quantification levels. When data in more 
than one of the data sets or categories described in section B.9.c.i 
through B.9.c.iii below exist, best professional judgment should be used 
to select the one data set that most accurately reflects or estimates 
background concentrations. Pollutant degradation and transport 
information may be considered when utilizing pollutant loading data.
    c. Calculation requirements. Except as provided below, the 
representative background concentration for a pollutant in the specified 
watershed, waterbody or waterbody segment shall be established on a 
case-by-case basis as the geometric mean of:
    i. Acceptable available water column data; or
    ii. Water column concentrations estimated through use of acceptable 
available caged or resident fish tissue data; or
    iii. Water column concentrations estimated through use of acceptable 
available or projected pollutant loading data.
    d. Detection considerations.
    i. Commonly accepted statistical techniques shall be used to 
evaluate data sets consisting of values both above and below the 
detection level.
    ii. When all of the acceptable available data in a data set or 
category, such as water column, caged or resident fish tissue or 
pollutant loading data, are below the level of detection for a 
pollutant, then all the data for that pollutant in that data set shall 
be assumed to be zero.
    10. Effluent Flow. If WLAs are expressed as concentrations of 
pollutants, the TMDL shall also indicate the point source effluent flows 
assumed in the analyses. Mass loading limitations established in NPDES 
permits must be consistent with both the WLA and assumed effluent flows 
used in establishing the TMDL.
    11. Reserved Allocations. TMDLs may include reserved allocations of 
loading capacity to accommodate future growth and additional sources. 
Where such reserved allocations are not included in a TMDL, any 
increased loadings of the pollutant for which the TMDL was developed 
that are due to a new or expanded discharge shall not be allowed unless 
the TMDL is revised in accordance with these proceudres to include an 
allocation for the new or expanded discharge.
    C. Mixing Zones for Bioaccumulative Chemicals of Concern (BCCs). The 
following requirements shall be applied in establishing TMDLs, WLAs in 
the absence of TMDLs, and preliminary WLAs for purposes of determining 
the need for WQBELs under procedure 5 of appendix F, for BCCs:
    1. There shall be no mixing zones available for new discharges of 
BCCs to the Great Lakes System. WLAs established through TMDLs, WLAs in 
the absence of TMDLs, and preliminary WLAs for purposes of determining 
the need for WQBELs for new discharges of BCCs shall be set no higher 
than the most stringent applicable water quality criteria or values for 
the BCCs in question. This prohibition takes effect for a Great Lakes 
State or Tribe on the date EPA approves the State's or Tribe's 
submission of such prohibition or publishes a notice under 40 CFR 
132.5(f) identifying that prohibition as applying to discharges within 
the State or Federal Tribal reservation.
    2. For purposes of section C of procedure 3 of appendix F, new 
discharges are defined as: (1) A ``discharge of pollutants'' (as defined 
in 40 CFR 122.2) to the Great Lakes System from a building, structure, 
facility, or installation, the construction of which commences after the 
date the prohibition in section C.1 takes effect in that State or Tribe; 
(2) a new discharge from an existing Great Lakes discharger that 
commences after the date the prohibition in section C.1 takes effect in 
that State or Tribe; or (3) an expanded discharge from an existing Great 
Lakes discharger that commences after the date the prohibition in 
section C.1 takes effect in that State or Tribe, except for those 
expanded discharges resulting from changes in loadings of any BCC within 
the existing capacity and processes (e.g., normal operational 
variability, changes in intake water pollutants, increasing the 
production hours of the facility or adding additional shifts, or 
increasing the rate of production), and that are covered by the existing 
applicable control document. Not included within the definition of ``new 
discharge'' are new or expanded discharges of BCCs from a publicly owned 
treatment works (POTW as defined at 40 CFR 122.2)

[[Page 666]]

when such discharges are necessary to prevent a public health threat to 
the community (e.g., a situation where a community with failing septic 
systems is connected to a POTW to avert a potential public health threat 
from these failing systems). These and all other discharges of BCCs are 
defined as existing discharges.
    3. Up until November 15, 2010, mixing zones for BCCs may be allowed 
for existing discharges to the Great Lakes System pursuant to the 
procedures specified in sections D and E of this procedure.
    4. Except as provided in sections C.5 and C.6 of this procedure, 
permits issued on or after this provision takes effect in a Great Lakes 
State or Tribe shall not authorize mixing zones for existing discharges 
of BCCs to the Great Lakes System after November 15, 2010. After 
November 15, 2010, WLAs established through TMDLs, WLAs established in 
the absence of TMDLs, and preliminary WLAs for purposes of determining 
the need for WQBELs under procedure 5 of appendix F for existing 
discharges of BCCs to the Great Lakes System shall be equal to the most 
stringent applicable water quality criteria or values for the BCCs in 
question.
    5. Exception for Water Conservation. Great Lakes States and Tribes 
may grant mixing zones for any existing discharge of BCCs to the Great 
Lakes System beyond the date specified in section C.4 of this procedure 
where it can be demonstrated, on a case-by-case basis, that failure to 
grant a mixing zone would preclude water conservation measures that 
would lead to overall load reductions in BCCs, even though higher 
concentrations of BCCs occur in the effluent. Such mixing zones must 
also be consistent with sections D and E of this procedure.
    6. Exception for Technical and Economic Considerations. Great Lakes 
States and Tribes may grant mixing zones beyond the date specified in 
section C.4 of this procedure for any existing discharge of a BCC to the 
Great Lakes System upon the request of a discharger, subject to sections 
C.6.a through C.6.c below.
    a. The State or Tribe must determine that:
    i. The discharger is in compliance with and will continue to 
implement, for the BCC in question, all applicable requirements of Clean 
Water Act sections 118, 301, 302, 303, 304, 306, 307, 401, and 402, 
including existing National Pollutant Discharge Elimination System 
(NPDES) water-quality based effluent limitations; and
    ii. The discharger has reduced and will continue to reduce the 
loading of the BCC for which a mixing zone is requested to the maximum 
extent possible, such that any additional controls or pollution 
prevention measures to reduce or ultimately eliminate the BCC discharge 
would result in unreasonable economic effects on the discharger or the 
affected community because the controls or measures are not feasible or 
cost-effective.
    b. Any mixing zone established pursuant to this section shall:
    i. Not result in any less stringent limitations than those existing 
prior to November 13, 2000;
    ii. Be no larger than necessary to account for the technical 
constraints and economic effects identified pursuant to paragraph 
C.6.a.ii above;
    iii. Meet all applicable acute and chronic aquatic life, wildlife 
and human health criteria and values within and at the edge of the 
mixing zone or be consistent with the applicable TMDL or assessment and 
remediation plan authorized under procedure 3.A.
    iv. Be accompanied, as appropriate, by a permit condition requiring 
the discharger to implement an ambient monitoring plan to ensure 
compliance with water quality standards and consistency with any 
applicable TMDL or such other strategy consistent with Section A of this 
procedure, including the evaluation of alternative means for reducing 
the BCC from other sources in the watershed; and
    v. Be limited to one permit term unless the permitting authority 
makes a new determination in accordance with this section for each 
successive permit application in which a mixing zone for the BCC is 
sought.
    c. For each draft NPDES permit that would allow a mixing zone for 
one or more BCCs after November 15, 2010, the fact sheet or statement of 
basis for the draft permit that is required to be made available through 
public notice under 40 CFR 124.6(e) shall:
    i. Specify the mixing provisions used in calculating the permit 
limits; and
    ii. Identify each BCC for which a mixing zone is proposed.
    7. Any mixing zone authorized under sections C.3, C.5 or C.6 must be 
consistent with sections D and E of this procedure, as applicable.
    D. Deriving TMDLs, WLAs, and LAs for Point and Nonpoint Sources: 
WLAs in the Absence of a TMDL; and Preliminary WLAs for Purposes of 
Determining the Need for WQBELs for OWGL. This section addresses 
conditions for deriving TMDLs for Open Waters of the Great Lakes (OWGL), 
inland lakes and other waters of the Great Lakes System with no 
appreciable flow relative to their volumes. State and Tribal procedures 
to derive TMDLs under this section must be consistent with (as 
protective as) the general conditions in section B of this procedure, 
CWA section 303(d), existing regulations (40 CFR 130.7), section C of 
this procedure, and sections D.1. through D.4 below. State and Tribal 
procedures to derive WLAs calculated in the absence of a TMDL and 
preliminary WLAs for purposes of determining the need for WQBELs under 
procedure 5 of appendix F

[[Page 667]]

must be consistent with sections B.9, C.1, C3 through C.6, and D. 1 
through D.4 of this procedure.
    1. Individual point source WLAs and preliminary WLAs for purposes of 
determining the need for WQBELs under procedure 5 of appendix F shall 
assume no greater dilution than one part effluent to 10 parts receiving 
water for implementation of numeric and narrative chronic criteria and 
values (including, but not limited to human cancer criteria, human 
cancer values, human noncancer values, human noncancer criteria, 
wildlife criteria, and chronic aquatic life criteria and values) unless 
an alternative mixing zone is demonstrated as appropriate in a mixing 
zone demonstration conducted pursuant to section F of this procedure. In 
no case shall a mixing zone be granted that exceeds the area where 
discharge-induced mixing occurs.
    2. Appropriate mixing zone assumptions to be used in calculating 
load allocations for nonpoint sources shall be determined, consistent 
with applicable State or Tribal requirements, on a case-by-case basis.
    3. WLAs and preliminary WLAs based on acute aquatic life criteria or 
values shall not exceed the Final Acute Value (FAV), unless a mixing 
zone demonstration is conducted and approved pursuant to section F of 
this procedure. If mixing zones from two or more proximate sources 
interact or overlap, the combined effect must be evaluated to ensure 
that applicable criteria and values will be met in the area where acute 
mixing zones overlap.
    4. In no case shall a mixing zone be granted that would likely 
jeopardize the continued existence of any endangered or threatened 
species listed under section 4 of the ESA or result in the destruction 
or adverse modification of such species' critical habitat.
    E. Deriving TMDLs, WLAs, and LAs for Point and Nonpoint Sources; 
WLAs in the Absence of a TMDL; and Preliminary WLAs for the Purposes of 
Determining the Need for WQBELs for Great Lakes Systems Tributaries and 
Connecting Channels. This section describes conditions for deriving 
TMDLs for tributaries and connecting channels of the Great Lakes System 
that exhibit appreciable flows relative to their volumes. State and 
Tribal procedures to derive TMDLs must be consistent with the general 
conditions listed in section B of this procedure, section C of this 
procedure, existing TMDL regulations (40 CFR 130.7) and specific 
conditions E.1 through E.5. State and Tribal procedures to derive WLAs 
calculated in the absence of a TMDL, and preliminary WLAs for purposes 
of determining reasonable potential under procedure 5 of this appendix 
for discharges to tributaries and connecting channels must be consistent 
with sections B.9, C.1, C.3 through C.6, and E.1 through E.5 of this 
procedure.
    1. Stream Design. These design flows must be used unless data exist 
to demonstrate that an alternative stream design flow is appropriate for 
stream-specific and pollutant-specific conditions. For purposes of 
calculating a TMDL, WLAs in the absence of a TMDL, or preliminary WLAs 
for the purposes of determining reasonable potential under procedure 5 
of this appendix, using a steady-state model, the stream design flows 
shall be:
    a. The 7-day, 10-year stream design flow (7Q10), or the 4-day, 3-
year biologically-based stream design flow for chronic aquatic life 
criteria or values;
    b. The 1-day, 10-year stream design flow (1Q10), for acute aquatic 
life criteria or values;
    c. The harmonic mean flow for human health criteria or values;
    d. The 90-day, 10-year flow (90Q10) for wildlife criteria.
    e. TMDLs, WLAs in the absence of TMDLs, and preliminary WLAs for the 
purpose of determining the need for WQBELs calculated using dynamic 
modelling do not need to incorporate the stream design flows specified 
in sections E.1.a through E.1.d of this procedure.
    2. Loading Capacity. The loading capacity is the greatest amount of 
loading that a water can receive without violating water quality 
standards. The loading capacity is initially calculated at the farthest 
downstream location in the watershed drainage basin. The maximum 
allowable loading consistent with the attainment of each applicable 
numeric criterion or value for a given pollutant is determined by 
multiplying the applicable criterion or value by the flow at the 
farthest downstream location in the tributary basin at the design flow 
condition described above. This loading is then compared to the loadings 
at sites within the basin to assure that applicable numeric criteria or 
values for a given pollutant are not exceeded at all applicable sites. 
The lowest load is then selected as the loading capacity.
    3. Polluant Degradation. TMDLs, WLAs in the absence of a TMDL and 
preliminary WLAs for purposes of determining the need for WQBELs under 
procedure 5 of appendix F shall be based on the assumption that a 
pollutant does not degrade. However, the regulatory authority may take 
into account degradation of the pollutant if each of the following 
conditions are met.
    a. Scientifically valid field studies or other relevant information 
demonstrate that degradation of the pollutant is expected to occur under 
the full range of environmental conditions expected to be encountered;
    b. Scientifically valid field studies or other relevant information 
address other factors that affect the level of pollutants in the water 
column including, but not limited to,

[[Page 668]]

resuspension of sediments, chemical speciation, and biological and 
chemical transformation.
    4. Acute Aquatic Life Criteria and Values. WLAs and LAs established 
in a TMDL, WLAs in the absence of a TMDL, and preliminary WLAs for the 
purpose of determining the need for WQBELs based on acute aquatic life 
criteria or values shall not exceed the FAV, unless a mixing zone 
demonstration is completed and approved pursuant to section F of this 
procedure. If mixing zones from two or more proximate sources interact 
or overlap, the combined effect must be evaluated to ensure that 
applicable criteria and values will be met in the area where any 
applicable acute mixing zones overlap. This acute WLA review shall 
include, but not be limited to, consideration of:
    a. The expected dilution under all effluent flow and concentration 
conditions at stream design flow;
    b. Maintenance of a zone of passage for aquatic organisms; and
    c. Protection of critical aquatic habitat.
    In no case shall a permitting authority grant a mixing zone that 
would likely jeopardize the continued existence of any endangered or 
threatened species listed under section 4 of the ESA or result in the 
destruction or adverse modification of such species' critical habitat.
    5. Chronic Mixing Zones. WLAs and LAs established in a TMDL, WLAs in 
the absence of a TMDL, and preliminary WLAs for the purposes of 
determining the need for WQBELs for protection of aquatic life, wildlife 
and human health from chronic effects shall be calculated using a 
dilution fraction no greater than 25 percent of the stream design flow 
unless a mixing zone demonstration pursuant to section F of this 
procedure is conducted and approved. A demonstration for a larger mixing 
zone may be provided, if approved and implemented in accordance with 
section F of this procedure. In no case shall a permitting authority 
grant a mixing zone that would likely jeopardize the continued existence 
of any endangered or threatened species listed under section 4 of the 
ESA or result in the destruction or adverse modification of such 
species' critical habitat.
    F. Mixing Zone Demonstration Requirements.
    1. For purposes of establishing a mixing zone other than as 
specified in sections D and E above, a mixing zone demonstration must:
    a. Describe the amount of dilution occurring at the boundaries of 
the proposed mixing zone and the size, shape, and location of the area 
of mixing, including the manner in which diffusion and dispersion occur;
    b. For sources discharging to the open waters of the Great Lakes 
(OWGLs), define the location at which discharge-induced mixing ceases;
    c. Document the substrate character and geomorphology within the 
mixing zone;
    d. Show that the mixing zone does not interfere with or block 
passage of fish or aquatic life;
    e. Show that the mixing zone will be allowed only to the extent that 
the level of the pollutant permitted in the waterbody would not likely 
jeopardize the continued existence of any endangered or threatened 
species listed under section 4 of the ESA or result in the destruction 
or adverse modification of such species' critical habitat;
    f. Show that the mixing zone does not extend to drinking water 
intakes;
    g. Show that the mixing zone would not otherwise interfere with the 
designated or existing uses of the receiving water or downstream waters;
    h. Document background water quality concentrations;
    i. Show that the mixing zone does not promote undesirable aquatic 
life or result in a dominance of nuisance species; and
    j. Provide that by allowing additional mixing/dilution:
    i. Substances will not settle to form objectionable deposits;
    ii. Floating debris, oil, scum, and other matter in concentrations 
that form nuisances will not be produced; and
    iii. Objectionable color, odor, taste or turbidity will not be 
produced.
    2. In addition, the mixing zone demonstration shall address the 
following factors:
    a. Whether or not adjacent mixing zones overlap;
    b. Whether organisms would be attracted to the area of mixing as a 
result of the effluent character; and
    c. Whether the habitat supports endemic or naturally occurring 
species.
    3. The mixing zone demonstration must be submitted to EPA for 
approval. Following approval of a mixing zone demonstration consistent 
with sections F.1 and F.2, adjustment to the dilution ratio specified in 
section D.1 of this procedure shall be limited to the dilution available 
in the area where discharger-induced mixing occurs.
    4. The mixing zone demonstration shall be based on the assumption 
that a pollutant does not degrade within the proposed mixing zone, 
unless:
    a. Scientifically valid field studies or other relevant information 
demonstrate that degradation of the pollutant is expected to occur under 
the full range of environmental conditions expected to be encountered; 
and
    b. Scientifically valid field studies or other relevant information 
address other factors that affect the level of pollutants in the water 
column including, but not limited to, resuspension of sediments, 
chemical speciation, and biological and chemical transformation.

                         Procedure 4: Additivity

    The Great Lakes States and Tribes shall adopt additivity provisions 
consistent with (as protective as) this procedure.
    A. The Great Lakes States and Tribes shall adopt provisions to 
protect human health from the potential adverse additive effects from 
both the noncarcinogenic and carcinogenic components of chemical 
mixtures in effluents. For the chlorinated dibenzo-p-dioxins (CDDs) and 
chlorinated dibenzofurans (CDFs) listed in Table 1, potential adverse 
additive effects in effluents shall be accounted for in accordance with 
section B of this procedure.
    B. Toxicity Equivalency Factors (TEFs)/Bioaccumulation Equivalency 
Factors (BEFs).
    1. The TEFs in Table 1 and BEFs in Table 2 shall be used when 
calculating a 2,3,7,8-TCDD toxicity equivalence concentration in 
effluent to be used when implementing both human health noncancer and 
cancer criteria. The chemical concentration of each CDDs and CDFs in 
effluent shall be converted to a 2,3,7,8-TCDD toxicity equivalence 
concentration in effluent by (a) multiplying the chemical concentration 
of each CDDs and CDFs in the effluent by the appropriate TEF in Table 1 
below, (b) multiplying each product from step (a) by the BEF for each 
CDDs and CDFs in Table 2 below, and (c) adding all final products from 
step (b). The equation for calculating the 2,3,7,8-TCDD toxicity 
equivalence concentration in effluent is:
[GRAPHIC] [TIFF OMITTED] TR23MR95.118

where:

(TEC)tcdd = 2,3,7,8-TCDD toxicity equivalence concentration 
          in effluent
(C)x = concentration of total chemical x in effluent
(TEF)x = TCDD toxicity equivalency factor for x
(BEF)x = TCDD bioaccumulation equivalency factor for x

    2. The 2,3,7,8-TCDD toxicity equivalence concentration in effluent 
shall be used when developing waste load allocations under procedure 3, 
preliminary waste load allocations for purposes of determining 
reasonable potential under procedure 5, and for purposes of establishing 
effluent quality limits under procedure 5.

   Procedure 5: Reasonable Potential To Exceed Water Quality Standards

    Great Lakes States and Tribes shall adopt provisions consistent with 
(as protective as) this procedure. If a permitting authority determines 
that a pollutant is or may be discharged into the Great Lakes System at 
a level which will cause, have the reasonable potential to cause, or 
contribute to an excursion above any Tier I criterion or Tier II value, 
the permitting authority shall incorporate a water quality-based 
effluent limitation (WQBEL) in an NPDES permit for the discharge of that 
pollutant. When facility-specific effluent monitoring data are 
available, the permitting authority shall make this determination by 
developing preliminary effluent limitations (PEL) and comparing those 
effluent limitations to the projected effluent quality (PEQ) of the 
discharge in accordance with the following procedures. In all cases, the 
permitting authority shall use any valid, relevant, representative 
information that indicates a reasonable potential to exceed any Tier I 
criterion or Tier II value.
    A. Developing Preliminary Effluent Limitations on the Discharge of a 
Pollutant From a Point Source.
    1. The permitting authority shall develop preliminary wasteload 
allocations (WLAs)

[[Page 670]]

for the discharge of the pollutant from the point source to protect 
human health, wildlife, acute aquatic life, and chronic aquatic life, 
based upon any existing Tier I criteria. Where there is no Tier I 
criterion nor sufficient data to calculate a Tier I criterion, the 
permitting authority shall calculate a Tier II value for such pollutant 
for the protection of human health, and aquatic life and the preliminary 
WLAs shall be based upon such values. Where there is insufficient data 
to calculate a Tier II value, the permitting authority shall apply the 
procedure set forth in section C of this procedure to determine whether 
data must be generated to calculate a Tier II value.
    2. The following provisions in procedure 3 of appendix F shall be 
used as the basis for determining preliminary WLAs in accordance with 
section 1 of this procedure: procedure 3.B.9, Background Concentrations 
of Pollutants; procedure 3.C, Mixing Zones for Bioaccumulative Chemicals 
of Concern (BCCs), procedures 3.C.1, and 3.C.3 through 3.C.6; procedure 
3.D, Deriving TMDLs for Discharges to Lakes (when the receiving water is 
an open water of the Great Lakes (OWGL), an inland lake or other water 
of the Great Lakes System with no appreciable flow relative to its 
volume); procedure 3.E, Deriving TMDLs, WLAs and Preliminary WLAs, and 
load allocations (LAs) for Discharges to Great Lakes System Tributaries 
(when the receiving water is a tributary or connecting channel of the 
Great Lakes that exhibits appreciable flow relative to its volume); and 
procedure 3.F, Mixing Zone Demonstration Requirements.
    3. The permitting authority shall develop PELs consistent with the 
preliminary WLAs developed pursuant to sections A.1 and A.2 of this 
procedure, and in accordance with existing State or Tribal procedures 
for converting WLAs into WQBELs. At a minimum:
    a. The PELs based upon criteria and values for the protection of 
human health and wildlife shall be expressed as monthly limitations;
    b. The PELs based upon criteria and values for the protection of 
aquatic life from chronic effects shall be expressed as either monthly 
limitations or weekly limitations; and
    c. The PELs based upon the criteria and values for the protection of 
aquatic life from acute effects shall be expressed as daily limitations.
    B. Determining Reasonable Potential Using Effluent Pollutant 
Concentration Data.
    If representative, facility-specific effluent monitoring data 
samples are available for a pollutant discharged from a point source to 
the waters of the Great Lakes System, the permitting authority shall 
apply the following procedures:
    1. The permitting authority shall specify the PEQ as the 95 percent 
confidence level of the 95th percentile based on a log-normal 
distribution of the effluent concentration; or the maximum observed 
effluent concentration, whichever is greater. In calculating the PEQ, 
the permitting authority shall identify the number of effluent samples 
and the coefficient of variation of the effluent data, obtain the 
appropriate multiplying factor from Table 1 of procedure 6 of appendix 
F, and multiply the maximum effluent concentration by that factor. The 
coefficient of variation of the effluent data shall be calculated as the 
ratio of the standard deviation of the effluent data divided by the 
arithmetic average of the effluent data, except that where there are 
fewer than ten effluent concentration data points the coefficient of 
variation shall be specified as 0.6. If the PEQ exceeds any of the PELs 
developed in accordance with section A.3 of this procedure, the 
permitting authority shall establish a WQBEL in a NPDES permit for such 
pollutant.
    2. In lieu of following the procedures under section B.1 of this 
procedure, the permitting authority may apply procedures consistent with 
the following:
    a. The permitting authority shall specify the PEQ as the 95th 
percentile of the distribution of the projected population of daily 
values of the facility-specific effluent monitoring data projected using 
a scientifically defensible statistical method that accounts for and 
captures the long-term daily variability of the effluent quality, 
accounts for limitations associated with sparse data sets and, unless 
otherwise shown by the effluent data set, assumes a lognormal 
distribution of the facility-specific effluent data. If the PEQ exceeds 
the PEL based on the criteria and values for the protection of aquatic 
life from acute effects developed in accordance with section A.3 of this 
procedure, the permitting authority shall establish a WQBEL in an NPDES 
permit for such pollutant;
    b. The permitting authority shall calculate the PEQ as the 95th 
percentile of the distribution of the projected population of monthly 
averages of the facility-specific effluent monitoring data using a 
scientifically defensible statistical method that accounts for and 
captures the long-term variability of the monthly average effluent 
quality, accounts for limitations associated with sparse data sets and, 
unless otherwise shown by the effluent data set, assumes a lognormal 
distribution of the facility-specific effluent data. If the PEQ exceeds 
the PEL based on criteria and values for the protection of aquatic life 
from chronic effects, human health or wildlife developed in accordance 
with section A.3 of this procedure, the permitting authority shall 
establish a WQBEL in an NPDES permit for such pollutant; and
    c. The permitting authority shall calculate the PEQ as the 95th 
percentile of the distribution of the projected population of weekly 
averages of the facility-specific effluent monitoring data using a 
scientifically

[[Page 671]]

defensible statistical method that accounts for and captures the long-
term variability of the weekly average effluent quality, accounts for 
limitations associated with sparse data sets and, unless otherwise shown 
by the effluent data set, assumes a lognormal distribution of the 
facility-specific effluent data. If the PEQ exceeds the PEL based on 
criteria and values to protect aquatic life from chronic effects 
developed in accordance with section A.3 of this procedure, the 
permitting authority shall establish a WQBEL in an NPDES permit for such 
pollutant.
    C. Developing Necessary Data to Calculate Tier II Values Where Such 
Data Does Not Currently Exist.
    1. Except as provided in sections C.2, C.4, or D of this procedure, 
for each pollutant listed in Table 6 of part 132 that a permittee 
reports as known or believed to be present in its effluent, and for 
which pollutant data sufficient to calculate Tier II values for non-
cancer human health, acute aquatic life and chronic aquatic life do not 
exist, the permitting authority shall take the following actions:
    a. The permitting authority shall use all available, relevant 
information, including Quantitative Structure Activity Relationship 
information and other relevant toxicity information, to estimate ambient 
screening values for such pollutant which will protect humans from 
health effects other than cancer, and aquatic life from acute and 
chronic effects.
    b. Using the procedures specified in sections A.1 and A.2 of this 
procedure, the permitting authority shall develop preliminary WLAs for 
the discharge of the pollutant from the point source to protect human 
health, acute aquatic life, and chronic aquatic life, based upon the 
estimated ambient screening values.
    c. The permitting authority shall develop PELs in accordance with 
section A.3 of this procedure, which are consistent with the preliminary 
WLAs developed in accordance with section C.1.b of this procedure.
    d. The permitting authority shall compare the PEQ developed 
according to the procedures set forth in section B of this procedure to 
the PELs developed in accordance with section C.1.c of this procedure. 
If the PEQ exceeds any of the PELs, the permitting authority shall 
generate or require the permittee to generate the data necessary to 
derive Tier II values for noncancer human health, acute aquatic life and 
chronic aquatic life.
    e. The data generated in accordance with section C.1.d of this 
procedure shall be used in calculating Tier II values as required under 
section A.1 of this procedure. The calculated Tier II value shall be 
used in calculating the preliminary WLA and PEL under section A of this 
procedure, for purposes of determining whether a WQBEL must be included 
in the permit. If the permitting authority finds that the PEQ exceeds 
the calculated PEL, a WQBEL for the pollutant or a permit limit on an 
indicator parameter consistent with 40 CFR 122.44(d)(1)(vi)(C) must be 
included in the permit.
    2. With the exception of bioaccumulative chemicals of concern 
(BCCs), a permitting authority is not required to apply the procedures 
set forth in section C.1 of this procedure or include WQBELs to protect 
aquatic life for any pollutant listed in Table 6 of part 132 discharged 
by an existing point source into the Great Lakes System, if:
    a. There is insufficient data to calculate a Tier I criterion or 
Tier II value for aquatic life for such pollutant;
    b. The permittee has demonstrated through a biological assessment 
that there are no acute or chronic effects on aquatic life in the 
receiving water; and
    c. The permittee has demonstrated in accordance with procedure 6 of 
this appendix that the whole effluent does not exhibit acute or chronic 
toxicity.
    3. Nothing in sections C.1 or C.2 of this procedure shall preclude 
or deny the right of a permitting authority to:
    a. Determine, in the absence of the data necessary to derive a Tier 
II value, that the discharge of the pollutant will cause, have the 
reasonable potential to cause, or contribute to an excursion above a 
narrative criterion for water quality; and
    b. Incorporate a WQBEL for the pollutant into an NPDES permit.
    4. If the permitting authority develops a WQBEL consistent with 
section C.3 of this procedure, and the permitting authority demonstrates 
that the WQBEL developed under section C.3 of this procedure is at least 
as stringent as a WQBEL that would have been based upon the Tier II 
value or values for that pollutant, the permitting authority shall not 
be obligated to generate or require the permittee to generate the data 
necessary to derive a Tier II value or values for that pollutant.
    D. Consideration of Intake Pollutants in Determining Reasonable 
Potential.
    1. General.
    a. Any procedures adopted by a State or Tribe for considering intake 
pollutants in water quality-based permitting shall be consistent with 
this section and section E.
    b. The determinations under this section and section E shall be made 
on a pollutant-by-pollutant, outfall-by-outfall, basis.
    c. This section and section E apply only in the absence of a TMDL 
applicable to the discharge prepared by the State or Tribe and approved 
by EPA, or prepared by EPA pursuant to 40 CFR 130.7(d), or in the 
absence of an assessment and remediation plan submitted and approved in 
accordance with procedure 3.A. of appendix F. This section and section

[[Page 672]]

E do not alter the permitting authority's obligation under 40 CFR 
122.44(d)(vii)(B) to develop effluent limitations consistent with the 
assumptions and requirements of any available WLA for the discharge, 
which is part of a TMDL prepared by the State or Tribe and approved by 
EPA pursuant to 40 CFR 130.7, or prepared by EPA pursuant to 40 CFR 
130.7(d).
    2. Definition of Same Body of Water.
    a. This definition applies to this section and section E of this 
procedure.
    b. An intake pollutant is considered to be from the same body of 
water as the discharge if the permitting authority finds that the intake 
pollutant would have reached the vicinity of the outfall point in the 
receiving water within a reasonable period had it not been removed by 
the permittee. This finding may be deemed established if:
    i. The background concentration of the pollutant in the receiving 
water (excluding any amount of the pollutant in the facility's 
discharge) is similar to that in the intake water;
    ii. There is a direct hydrological connection between the intake and 
discharge points; and
    iii. Water quality characteristics (e.g., temperature, Ph, hardness) 
are similar in the intake and receiving waters.
    c. The permitting authority may also consider other site-specific 
factors relevant to the transport and fate of the pollutant to make the 
finding in a particular case that a pollutant would or would not have 
reached the vicinity of the outfall point in the receiving water within 
a reasonable period had it not been removed by the permittee.
    d. An intake pollutant from groundwater may be considered to be from 
the same body of water if the permitting authority determines that the 
pollutant would have reached the vicinity of the outfall point in the 
receiving water within a reasonable period had it not been removed by 
the permittee, except that such a pollutant is not from the same body of 
water if the groundwater contains the pollutant partially or entirely 
due to human activity, such as industrial, commercial, or municipal 
operations, disposed actions, or treatment processes.
    e. An intake pollutant is the amount of a pollutant that is present 
in waters of the United States (including groundwater as provided in 
section D.2.d of this procedure) at the time it is withdrawn from such 
waters by the discharger or other facility (e.g., public water supply) 
supplying the discharger with intake water.
    3. Reasonable Potential Determination.
    a. The permitting authority may use the procedure described in this 
section of procedure 5 in lieu of procedures 5.A through C provided the 
conditions specified below are met.
    b. The permitting authority may determine that there is no 
reasonable potential for the discharge of an identified intake pollutant 
or pollutant parameter to cause or contribute to an excursion above a 
narrative or numeric water quality criterion within an applicable water 
quality standard where a discharger demonstrates to the satisfaction of 
the permitting authority (based upon information provided in the permit 
application or other information deemed necessary by the permitting 
authority) that:
    i. The facility withdraws 100 percent of the intake water containing 
the pollutant from the same body of water into which the discharge is 
made;
    ii. The facility does not contribute any additional mass of the 
identified intake pollutant to its wastewater;
    iii. The facility does not alter the identified intake pollutant 
chemically or physically in a manner that would cause adverse water 
quality impacts to occur that would not occur if the pollutants were 
left in-stream;
    iv. The facility does not increase the identified intake pollutant 
concentration, as defined by the permitting authority, at the edge of 
the mixing zone, or at the point of discharge if a mixing zone is not 
allowed, as compared to the pollutant concentration in the intake water, 
unless the increased concentration does not cause or contribute to an 
excursion above an applicable water quality standard; and
    v. The timing and location of the discharge would not cause adverse 
water quality impacts to occur that would not occur if the identified 
intake pollutant were left in-stream.
    c. Upon a finding under section D.3.b of this procedure that a 
pollutant in the discharge does not cause, have the reasonable potential 
to cause, or contribute to an excursion above an applicable water 
quality standard, the permitting authority is not required to include a 
WQBEL for the identified intake pollutant in the facility's permit, 
provided:
    i. The NPDES permit fact sheet or statement of basis includes a 
specific determination that there is no reasonable potential for the 
discharge of an identified intake pollutant to cause or contribute to an 
excursion above an applicable narrative or numeric water quality 
criterion and references appropriate supporting documentation included 
in the administrative record;
    ii. The permit requires all influent, effluent, and ambient 
monitoring necessary to demonstrate that the conditions in section D.3.b 
of this procedure are maintained during the permit term; and
    iii. The permit contains a reopener clause authorizing modification 
or revocation and reissuance of the permit if new information indicates 
changes in the conditions in section D.3.b of this procedure.

[[Page 673]]

    d. Absent a finding under section D.3.b of this procedure that a 
pollutant in the discharge does not cause, have the reasonable potential 
to cause, or contribute to an excursion above an applicable water 
quality standard, the permitting authority shall use the procedures 
under sections 5.A through C of this procedure to determine whether a 
discharge causes, has the reasonable potential to cause, or contribute 
to an excursion above an applicable narrative or numeric water quality 
criterion.
    E. Consideration of Intake Pollutants in Establishing WQBELs.
    1. General. This section applies only when the concentration of the 
pollutant of concern upstream of the discharge (as determined using the 
provisions in procedure 3.B.9 of appendix F) exceeds the most stringent 
applicable water quality criterion for that pollutant.
    2. The requirements of sections D.1-D.2 of this procedure shall also 
apply to this section.
    3. Intake Pollutants from the Same Body of Water.
    a. In cases where a facility meets the conditions in sections 
D.3.b.i and D.3.b.iii through D.3.b.v of this procedure, the permitting 
authority may establish effluent limitations allowing the facility to 
discharge a mass and concentration of the pollutant that are no greater 
than the mass and concentration of the pollutant identified in the 
facility's intake water (``no net addition limitations''). The permit 
shall specify how compliance with mass and concentration limitations 
shall be assessed. No permit may authorize ``no net addition 
limitations'' which are effective after March 23, 2007. After that date, 
WQBELs shall be established in accordance with procedure 5.F.2 of 
appendix F.
    b. Where proper operation and maintenance of a facility's treatment 
system results in removal of a pollutant, the permitting authority may 
establish limitations that reflect the lower mass and/or concentration 
of the pollutant achieved by such treatment, taking into account the 
feasibility of establishing such limits.
    c. For pollutants contained in intake water provided by a water 
system, the concentration of the intake pollutant shall be determined at 
the point where the raw water supply is removed from the same body of 
water, except that it shall be the point where the water enters the 
water supplier's distribution system where the water treatment system 
removes any of the identified pollutants from the raw water supply. Mass 
shall be determined by multiplying the concentration of the pollutant 
determined in accordance with this paragraph by the volume of the 
facility's intake flow received from the water system.
    4. Intake Pollutants from a Different Body of Water. Where the 
pollutant in a facility's discharge originates from a water of the 
United States that is not the same body of water as the receiving water 
(as determined in accordance with section D.2 of this procedure), WQBELs 
shall be established based upon the most stringent applicable water 
quality criterion for that pollutant.
    5. Multiple Sources of Intake Pollutants. Where a facility 
discharges intake pollutants that originate in part from the same body 
of water, and in part from a different body of water, the permitting 
authority may apply the procedures of sections E.3 and E.4 of this 
procedure to derive an effluent limitation reflecting the flow-weighted 
average of each source of the pollutant, provided that adequate 
monitoring to determine compliance can be established and is included in 
the permit.
    F. Other Applicable Conditions.
    1. In addition to the above procedures, effluent limitations shall 
be established to comply with all other applicable State, Tribal and 
Federal laws and regulations, including technology-based requirements 
and antidegradation policies.
    2. Once the permitting authority has determined in accordance with 
this procedure that a WQBEL must be included in an NPDES permit, the 
permitting authority shall:
    a. Rely upon the WLA established for the point source either as part 
of any TMDL prepared under procedure 3 of this appendix and approved by 
EPA pursuant to 40 CFR 130.7, or as part of an assessment and 
remediation plan developed and approved in accordance with procedure 3.A 
of this appendix, or, in the absence of such TMDL or plan, calculate 
WLAs for the protection of acute and chronic aquatic life, wildlife and 
human health consistent with the provisions referenced in section A.1 of 
this procedure for developing preliminary wasteload allocations, and
    b. Develop effluent limitations consistent with these WLAs in 
accordance with existing State or Tribal procedures for converting WLAs 
into WQBELs.
    3. When determining whether WQBELs are necessary, information from 
chemical-specific, whole effluent toxicity and biological assessments 
shall be considered independently.
    4. If the geometric mean of a pollutant in fish tissue samples 
collected from a waterbody exceeds the tissue basis of a Tier I 
criterion or Tier II value, after consideration of the variability of 
the pollutant's bioconcentration and bioaccumulation in fish, each 
facility that discharges detectable levels of such pollutant to that 
water has the reasonable potential to cause or contribute to an 
excursion above a Tier I criteria or a Tier II value and the permitting 
authority

[[Page 674]]

shall establish a WQBEL for such pollutant in the NPDES permit for such 
facility.

            Procedure 6: Whole Effluent Toxicity Requirements

    The Great Lakes States and Tribes shall adopt provisions consistent 
with (as protective as) procedure 6 of appendix F of part 132.
    The following definitions apply to this part:
    Acute toxic unit (TUa). 100/LC50 where the 
LC50 is expressed as a percent effluent in the test medium of 
an acute whole effluent toxicity (WET) test that is statistically or 
graphically estimated to be lethal to 50 percent of the test organisms.
    Chronic toxic unit (TUc). 100/NOEC or 100/
IC25, where the NOEC and IC25 are expressed as a 
percent effluent in the test medium.
    Inhibition concentration 25 (IC25). The toxicant 
concentration that would cause a 25 percent reduction in a non-quantal 
biological measurement for the test population. For example, the 
IC25 is the concentration of toxicant that would cause a 25 
percent reduction in mean young per female or in growth for the test 
population.
    No observed effect concentration (NOEC). The highest concentration 
of toxicant to which organisms are exposed in a full life-cycle or 
partial life-cycle (short-term) test, that causes no observable adverse 
effects on the test organisms (i.e., the highest concentration of 
toxicant in which the values for the observed responses are not 
statistically significantly different from the controls).
    A. Whole Effluent Toxicity Requirements. The Great Lakes States and 
Tribes shall adopt whole effluent toxicity provisions consistent with 
the following:
    1. A numeric acute WET criterion of 0.3 acute toxic units 
(TUa) measured pursuant to test methods in 40 CFR part 136, 
or a numeric interpretation of a narrative criterion establishing that 
0.3 TUa measured pursuant to test methods in 40 CFR part 136 
is necessary to protect aquatic life from acute effects of WET. At the 
discretion of the permitting authority, the foregoing requirement shall 
not apply in an acute mixing zone that is sized in accordance with EPA-
approved State and Tribal methods.
    2. A numeric chronic WET criterion of one chronic toxicity unit 
(TUc) measured pursuant to test methods in 40 CFR part 136, 
or a numeric interpretation of a narrative criterion establishing that 
one TUc measured pursuant to test methods in 40 CFR part 136 
is necessary to protect aquatic life from the chronic effects of WET. At 
the discretion of the permitting authority, the foregoing requirements 
shall not apply within a chronic mixing zone consistent with: (a) 
procedures 3.D.1 and 3.D.4, for discharges to the open of the Great 
Lakes (OWGL), inland lakes and other waters of the Great Lakes System 
with no appreciable flow relative to their volume, or (b) procedure 
3.E.5 for discharges to tributaries and connecting channels of the Great 
Lakes System.
    B. WET Test Methods. All WET tests performed to implement or 
ascertain compliance with this procedure shall be performed in 
accordance with methods established in 40 CFR part 136.
    C. Permit Conditions.
    1. Where a permitting authority determines pursuant to section D of 
this procedure that the WET of an effluent is or may be discharged at a 
level that will cause, have the reasonable potential to cause, or 
contribute to an excursion above any numeric WET criterion or narrative 
criterion within a State's or Tribe's water quality standards, the 
permitting authority:
    a. Shall (except as provided in section C.1.e of this procedure) 
establish a water quality-based effluent limitation (WQBEL) or WQBELs 
for WET consistent with section C.1.b of this procedure;
    b. Shall calculate WQBELs pursuant to section C.1.a. of this 
procedure to ensure attainment of the State's or Tribe's chronic WET 
criteria under receiving water flow conditions described in procedures 
3.E.1.a (or where applicable, with procedure 3.E.1.e) for Great Lakes 
System tributaries and connecting channels, and with mixing zones no 
larger than allowed pursuant to section A.2. of this procedure. Shall 
calculate WQBELs to ensure attainment of the State's or Tribe's acute 
WET criteria under receiving water flow conditions described in 
procedure 3.E.1.b (or where applicable, with procedure 3.E.1.e) for 
Great Lakes System tributaries and connecting channels, with an 
allowance for mixing zones no greater than specified pursuant to section 
A.1 of this procedure.
    c. May specify in the NPDES permit the conditions under which a 
permittee would be required to perform a toxicity reduction evaluation.
    d. May allow with respect to any WQBEL established pursuant to 
section C.1.a of this procedure an appropriate schedule of compliance 
consistent with procedure 9 of appendix F; and
    e. May decide on a case-by-case basis that a WQBEL for WET is not 
necessary if the State's or Tribe's water quality standards do not 
contain a numeric criterion for WET, and the permitting authority 
demonstrates in accordance with 40 CFR 122.44(d)(1)(v) that chemical-
specific effluent limits are sufficient to ensure compliance with 
applicable criteria.
    2. Where a permitting authority lacks sufficient information to 
determine pursuant to section D of this procedure whether the WET of an 
effluent is or may be discharged at levels that will cause, have the 
reasonable potential to cause, or contribute to an excursion above any 
numeric WET criterion or narrative criterion within a State's or

[[Page 675]]

Tribe's water quality standards, then the permitting authority should 
consider including in the NPDES permit appropriate conditions to require 
generation of additional data and to control toxicity if found, such as:
    a. WET testing requirements to generate the data needed to 
adequately characterize the toxicity of the effluent to aquatic life;
    b. Language requiring a permit reopener clause to establish WET 
limits if any toxicity testing data required pursuant to section C.2.a 
of this procedure indicate that the WET of an effluent is or may be 
discharged at levels that will cause, have the reasonable potential to 
cause, or contribute to an excursion above any numeric WET criterion or 
narrative criterion within a State's or Tribe's water quality standards.
    3. Where sufficient data are available for a permitting authority to 
determine pursuant to section D of this procedure that the WET of an 
effluent neither is nor may be discharged at a level that will cause, 
have the reasonable potential to cause, or contribute to an excursion 
above any numeric WET criterion or narrative criterion within a State's 
or Tribe's water quality standards, the permitting authority may include 
conditions and limitations described in section C.2 of this procedure at 
its discretion.
    D. Reasonable Potential Determinations. The permitting authority 
shall take into account the factors described in 40 CFR 122.44(d)(1)(ii) 
and, where representative facility-specific WET effluent data are 
available, apply the following requirements in determining whether the 
WET of an effluent is or may be discharged at a level that will cause, 
have the reasonable potential to cause, or contribute to an excursion 
above any numeric WET criterion or narrative criterion within a State's 
or Tribe's water quality standards.
    1. The permitting authority shall characterize the toxicity of the 
discharge by:
    a. Either averaging or using the maximum of acute toxicity values 
collected within the same day for each species to represent one daily 
value. The maximum of all daily values for the most sensitive species 
tested is used for reasonable potential determinations;
    b. Either averaging or using the maximum of chronic toxicity values 
collected within the same calendar month for each species to represent 
one monthly value. The maximum of such values, for the most sensitive 
species tested, is used for reasonable potential determinations:
    c. Estimating the toxicity values for the missing endpoint using a 
default acute-chronic ratio (ACR) of 10, when data exist for either 
acute WET or chronic WET, but not for both endpoints.
    2. The WET of an effluent is or may be discharged at a level that 
will cause, have the reasonable potential to cause, or contribute to an 
excursion above any numeric acute WET criterion or numeric 
interpretation of a narrative criterion within a State's or Tribe's 
water quality standards, when effluent-specific information demonstrates 
that:

(TUa effluent) (B) (effluent flow/(Qad + effluent 
flow))AC

Where TUa effluent is the maximum measured acute toxicity of 
100 percent effluent determined pursuant to section D.1.a. of this 
procedure, B is the multiplying factor taken from Table F6-1 of this 
procedure to convert the highest measured effluent toxicity value to the 
estimated 95th percentile toxicity value for the discharge, effluent 
flow is the same effluent flow used to calculate the preliminary 
wasteload allocations (WLAs) for individual pollutants to meet the acute 
criteria and values for those pollutants, AC is the numeric acute WET 
criterion or numeric interpretation of a narrative criterion established 
pursuant to section A.1 of this procedure and expressed in 
TUa, and Qad is the amount of the receiving water available 
for dilution calculated using: (i) the specified design flow(s) for 
tributaries and connecting channels in section C.1.b of this procedure, 
or where appropriate procedure 3.E.1.e of appendix F, and using EPA-
approved State and Tribal procedures for establishing acute mixing zones 
in tributaries and connecting channels, or (ii) the EPA-approved State 
and Tribal procedures for establishing acute mixing zones in OWGLs. 
Where there are less than 10 individual WET tests, the multiplying 
factor taken from Table F6-1 of this procedure shall be based on a 
coefficient of variation (CV) or 0.6. Where there are 10 or more 
individual WET tests, the multiplying factor taken from Table F6-1 shall 
be based on a CV calculated as the standard deviation of the acute 
toxicity values found in the WET tests divided by the arithmetic mean of 
those toxicity values.
    3. The WET of an effluent is or may be discharged at a level that 
will cause, have the reasonable potential to cause, or contribute to an 
excursion above any numeric chronic WET criterion or numeric 
interpretation of a narrative criterion within a State's or Tribe's 
water quality standards, when effluent-specific information demonstrates 
that:

(TUc effluent) (B) (effluent flow/Qad + effluent 
flow))CC

Where TUc effluent is the maximum measured chronic toxicity 
value of 100 percent effluent determined in accordance with section 
D.1.b. of this procedure, B is the multiplying factor taken from Table 
F6-1 of this procedure, effluent flow is the same effluent flow used to 
calculate the preliminary WLAs for individual pollutants to meet the 
chronic criteria and values for those pollutants, CC is the numeric 
chronic WET criterion or numeric interpretation of a narrative criterion 
established pursuant to section A.2 of this procedure and expressed in 
TUc, and Qad

[[Page 676]]

is the amount of the receiving water available for dilution calculated 
using: (i) the design flow(s) for tributaries and connecting channels 
specified in procedure 3.E.1.a of appendix F, and where appropriate 
procedure 3.E.1.e of appendix F, and in accordance with the provisions 
of procedure 3.E.5 for chronic mixing zones, or (ii) procedures 3.D.1 
and 3.D.4 for discharges to the OWGLs. Where there are less than 10 
individual WET tests, the multiplying factor taken from Table F6-1 of 
this procedure shall be based on a CV of 0.6. Where there are 10 more 
individual WET tests, the multiplying factor taken from Table F6-1 of 
this procedure shall be based on a CV calculated as the standard 
deviation of the WET tests divided by the arithmetic mean of the WET 
tests.

                       Procedure 7: Loading Limits

    The Great Lakes States and Tribes shall adopt provisions consistent 
with (as protective as) this procedure.
    Whenever a water quality-based effluent limitation (WQBEL) is 
developed, the WQBEL shall be expressed as both a concentration value 
and a corresponding mass loading rate.
    A. Both mass and concentration limits shall be based on the same 
permit averaging periods such as daily, weekly, or monthly averages, or 
in other appropriate permit averaging periods.
    B. The mass loading rates shall be calculated using effluent flow 
rates that are consistent with those used in establishing the WQBELs 
expressed in concentration.

    Procedure 8: Water Quality-based Effluent Limitations Below the 
                          Quantification Level

    The Great Lakes States and Tribes shall adopt provisions consistent 
with (as protective as) this procedure.
    When a water quality-based effluent limitation (WQBEL) for a 
pollutant is calculated to be less than the quantification level:
    A. Permit Limits. The permitting authority shall designate as the 
limit in the NPDES permit the WQBEL exactly as calculated.
    B. Analytical Method and Quantification Level.
    1. The permitting authority shall specify in the permit the most 
sensitive, applicable, analytical method, specified in or approved under 
40 CFR part 136, or other appropriate method if one is not available 
under 40 CFR part 136, to be used to monitor for the presence and amount 
in an effluent of the pollutant for which the WQBEL is established; and 
shall specify in accordance with section B.2 of this procedure, the 
quantification level that can be achieved by use of the specified 
analytical method.
    2. The quantification level shall be the minimum level (ML) 
specified in or approved under 40 CFR part 136 for the method for that 
pollutant. If no such ML exists, or if the method is not specified or 
approved under 40 CFR part 136, the quantification level shall be the 
lowest quantifiable level practicable. The permitting authority may 
specify a higher quantification level if the permittee demonstrates that 
a higher quantification level is appropriate because of effluent-
specific matrix interference.
    3. The permit shall state that, for the purpose of compliance 
assessment, the analytical method specified in the permit shall be used 
to monitor the amount of pollutant in an effluent down to the 
quantification level, provided that the analyst has complied with the 
specified quality assurance/quality control procedures in the relevant 
method.
    4. The permitting authority shall use applicable State and Tribal 
procedures to average and account for monitoring data. The permitting 
authority may specify in the permit the value to be used to interpret 
sample values below the quantification level.
    C. Special Conditions. The permit shall contain a reopener clause 
authorizing modification or revocation and reissuance of the permit if 
new information generated as a result of special conditions included in 
the permit indicates that presence of the pollutant in the discharge at 
levels above the WQBEL. Special conditions that may be included in the 
permit include, but are not limited to, fish tissue sampling, whole 
effluent toxicity (WET) tests, limits and/or monitoring requirements on 
internal waste streams, and monitoring for surrogate parameters. Data 
generated as a result of special conditions can be used to reopen the 
permit to establish more stringent effluent limits or conditions, if 
necessary.
    D. Pollutant Minimization Program. The permitting authority shall 
include a condition in the permit requiring the permittee to develop and 
conduct a pollutant minimization program for each pollutant with a WQBEL 
below the quantification level. The goal of the pollutant minimization 
program shall be to maintain the effluent at or below the WQBEL. In 
addition, States and Tribes may consider cost-effectiveness when 
evaluating the requirements of a PMP. The pollutant minimization program 
shall include, but is not limited to, the following:
    1. An annual review and semi-annual monitoring of potential sources 
of the pollutant, which may include fish tissue monitoring and other 
bio-uptake sampling;
    2. Quarterly monitoring for the pollutant in the influent to the 
wastewater treatment system;
    3. Submittal of a control strategy designed to proceed toward the 
goal of maintaining the effluent below the WQBEL;
    4. Implementation of appropriate, cost-effective control measures 
consistent with the control strategy; and
    5. An annual status report that shall be sent to the permitting 
authority including:
    a. All minimization program monitoring results for the previous 
year;
    b. A list of potential sources of the pollutant; and
    c. A summary of all action undertaken pursuant to the control 
strategy.
    6. Any information generated as a result of procedure 8.D can be 
used to support a request for subsequent permit modifications, including 
revisions to (e.g., more or less frequent monitoring), or removal of the 
requirements of procedure 8.D, consistent with 40 CFR 122.44, 122.62 and 
122.63.

                    Procedure 9: Compliance Schedules

    The Great Lakes States and Tribes shall adopt provisions consistent 
with (as protective as) procedure 9 of appendix F of part 132.
    A. Limitations for New Great Lakes Dischargers. When a permit issued 
on or after March 23, 1997 to a new Great Lakes discharger (defined in 
Part 132.2) contains a water quality-based effluent limitation (WQBEL), 
the permittee shall comply with such a limitation upon the commencement 
of the discharge.
    B. Limitations for Existing Great Lakes Dischargers.
    1. Any existing permit that is reissued or modified on or after 
March 23, 1997 to contain a new or more restrictive WQBEL may allow a 
reasonable period of time, up to five years from the date of permit 
issuance or modification, for the permittee to comply with that limit, 
provided that the Tier I criterion or whole effluent toxicity (WET) 
criterion was adopted (or, in the case of a narrative criterion, Tier II 
value, or Tier I criterion derived pursuant to the methodology in 
appendix A of part 132, was newly derived) after July 1, 1977.
    2. When the compliance schedule established under paragraph 1 goes 
beyond the term of the permit, an interim permit limit effective upon 
the expiration date shall be included in the permit and addressed in the 
permit's fact sheet or statement of basis. The administrative record for 
the permit shall reflect the final limit and its compliance date.
    3. If a permit establishes a schedule of compliance under paragraph 
1 which exceeds one year from the date of permit issuance or 
modification, the schedule shall set forth interim requirements and 
dates for their achievement. The time between such interim dates may not 
exceed one year. If the time necessary for completion of any interim 
requirement is more than one year and is not readily divisible into 
stages for completion, the permit shall require, at a minimum, specified 
dates for annual submission of progress reports on the status of any 
interim requirements.
    C. Delayed Effectiveness of Tier II Limitations for Existing Great 
Lakes Discharges.
    1. Whenever a limit (calculated in accordance with Procedure 3) 
based upon a Tier II value is included in a reissued or modified permit 
for an existing Great Lakes discharger, the permit may provide a 
reasonable period of time, up to two years, in which to provide 
additional studies necessary to develop a Tier I criterion or to modify 
the Tier II value. In such cases, the permit shall require compliance 
with the Tier II limitation within a reasonable period of time, no later 
than five years after permit issuance or modification, and contain a 
reopener clause.
    2. The reopener clause shall authorize permit modifications if 
specified studies have been completed by the permittee or provided by a 
third-party during the time allowed to conduct the specified studies, 
and the permittee or a third-party demonstrates, through such studies, 
that a revised limit is appropriate. Such a revised limit shall be 
incorporated through a permit modification and a reasonable time period, 
up to five years, shall be allowed for compliance. If incorporated prior 
to the compliance date of the original Tier II limitation, any such 
revised limit shall not be considered less-stringent for purposes of the 
anti-backsliding provisions of section 402(o) of the Clean Water Act.
    3. If the specified studies have been completed and do not 
demonstrate that a revised limit is appropriate, the permitting 
authority may provide a reasonable additional period of time, not to 
exceed five years with which to achieve compliance with the original 
effluent limitation.
    4. Where a permit is modified to include new or more stringent 
limitations, on a date within five years of the permit expiration date, 
such compliance schedules may extend beyond the term of a permit 
consistent with section B.2 of this procedure.
    5. If future studies (other than those conducted under paragraphs 1, 
2, or 3 above) result in a Tier II value being changed to a less 
stringent Tier II value or Tier I criterion, after the effective date of 
a Tier II-based limit, the existing Tier II-based limit may be revised 
to be less stringent if:
    (a) It complies with sections 402(o) (2) and (3) of the CWA; or,
    (b) In non-attainment waters, where the existing Tier II limit was 
based on procedure 3, the cumulative effect of revised effluent 
limitation based on procedure 3 of this appendix will assure compliance 
with water quality standards; or,
    (c) In attained waters, the revised effluent limitation complies 
with the State or Tribes' antidegradation policy and procedures.

Sec. 133.102  Secondary treatment.

    The following paragraphs describe the minimum level of effluent 
quality attainable by secondary treatment in terms of the parameters--
BOD5, SS and

[[Page 681]]

pH. All requirements for each parameter shall be achieved except as 
provided for in Sec. Sec. 133.103 and 133.105.
    (a) BOD5.
    (1) The 30-day average shall not exceed 30 mg/l.
    (2) The 7-day average shall not exceed 45 mg/l.
    (3) The 30-day average percent removal shall not be less than 85 
percent.
    (4) At the option of the NPDES permitting authority, in lieu of the 
parameter BOD5 and the levels of the effluent quality 
specified in paragraphs (a)(1), (a)(2) and (a)(3), the parameter 
CBOD5 may be substituted with the following levels of the 
CBOD5 effluent quality provided:
    (i) The 30-day average shall not exceed 25 mg/l.
    (ii) The 7-day average shall not exceed 40 mg/l.

limits of 6.0 to 9.0 unless the publicly owned treatment works 
demonstrates that: (1) Inorganic chemicals are not added to the waste 
stream as part of the treatment process; and (2) contributions from 
industrial sources do not cause the pH of the effluent to be less than 
6.0 or greater than 9.0.

[49 FR 37006, Sept. 20, 1984; 49 FR 40405, Oct. 16, 1984]



Sec. 133.103  Special considerations.

    (a) Combined sewers. Treatment works subject to this part may not be 
capable of meeting the percentage removal requirements established under 
Sec. Sec. 133.102(a)(3) and 133.102(b)(3), or Sec. Sec. 133.105(a)(3) 
and 133.105(b)(3) during wet weather where the treatment works receive 
flows from combined sewers (i.e., sewers which are designed to transport 
both storm water and sanitary sewage). For such treatment works, the 
decision must be made on a case-by-case basis as to whether any 
attainable percentage removal level can be defined, and if so, what the 
level should be.
    (b) Industrial wastes. For certain industrial categories, the 
discharge to navigable waters of BOD5 and SS permitted under 
sections 301(b)(1)(A)(i), (b)(2)(E) or 306 of the Act may be less 
stringent than the values given in Sec. Sec. 133.102(a)(1), 
133.102(a)(4)(i), 133.102(b)(1), 133.105(a)(1), 133.105(b)(1) and 
133.105(e)(1)(i). In cases when wastes would be introduced from such an 
industrial category into a publicly owned treatment works, the values 
for BOD5 and SS in Sec. Sec. 133.102(a)(1), 
133.102(a)(4)(i), 133.102(b)(1), 133.105(a)(1), 133.105(b)(1), and 
133.105(e)(1)(i) may be adjusted upwards provided that: (1) The 
permitted discharge of such pollutants, attributable to the industrial 
category, would not be greater than that which would be permitted under 
sections 301(b)(1)(A)(i), 301(b)(2)(E) or 306 of the Act if such 
industrial category were to discharge directly into the navigable 
waters, and (2) the flow or loading of such pollutants introduced by the 
industrial category exceeds 10 percent of the design flow or loading of 
the publicly owned treatment works. When such an adjustment is made, the 
values for BOD5 or SS in Sec. Sec. 133.102(a)(2), 
133.102(a)(4)(ii), Sec. 133.102(b)(2), 133.105(a)(2), 133.105(b)(2), 
and 133.105(e)(1)(ii) should be adjusted proportionately.
    (c) Waste stabilization ponds. The Regional Administrator, or, if 
appropriate, State Director subject to EPA approval, is authorized to 
adjust the minimum levels of effluent quality set forth in Sec. 133.105 
(b)(1), (b)(2), and (b)(3) for treatment works subject to this part, to 
conform to the SS concentrations achievable with waste stabilization 
ponds, provided that: (1) Waste stablization ponds are the principal 
process used for secondary treatment; and (2) operation and maintenance 
data indicate that the SS values specified in Sec. 133.105 (b)(1), 
(b)(2), and (b)(3) cannot be achieved. The term ``SS concentrations 
achievable with waste stabilization ponds'' means a SS value, determined 
by the Regional Administrator, or, if appropriate, State Director 
subject to EPA approval, which is equal to the effluent concentration 
achieved 90

[[Page 682]]

percent of the time within a State or appropriate contiguous 
geographical area by waste stabilization ponds that are achieving the 
levels of effluent quality for BOD5 specified in Sec. 
133.105(a)(1). [cf. 43 FR 55279].
    (d) Less concentrated influent wastewater for separate sewers. The 
Regional Administrator or, if appropriate, State Director is authorized 
to substitute either a lower percent removal requirement or a mass 
loading limit for the percent removal requirements set forth in 
Sec. Sec. 133.102(a)(3), 133.102(a)(4)(iii), 133.102(b)(3), 
102.105(a)(3), 133.105(b)(3) and 133.105(e)(1)(iii) provided that the 
permittee satisfactorily demonstrates that: (1) The treatment works is 
consistently meeting, or will consistently meet, its permit effluent 
concentration limits but its percent removal requirements cannot be met 
due to less concentrated influent wastewater, (2) to meet the percent 
removal requirements, the treatment works would have to achieve 
significantly more stringent limitations than would otherwise be 
required by the concentration-based standards, and (3) the less 
concentrated influent wastewater is not the result of excessive I/I. The 
determination of whether the less concentrated wastewater is the result 
of excessive I/I will use the definition of excessive I/I in 40 CFR 
35.2005(b)(16) plus the additional criterion that inflow is nonexcessive 
if the total flow to the POTW (i.e., wastewater plus inflow plus 
infiltration) is less than 275 gallons per capita per day.
    (e) Less concentrated influent wastewater for combined sewers during 
dry weather. The Regional Administrator or, if appropriate, the State 
Director is authorized to substitute either a lower percent removal 
requirement or a mass loading limit for the percent removal requirements 
set forth in Sec. Sec. 133.102(a)(3), 133.102(a)(4)(iii), 
133.102(b)(3), 133.105(a)(3), 133.105(b)(3) and 133.105(e)(1)(iii) 
provided that the permittee satisfactorily demonstrates that: (1) The 
treatment works is consistently meeting, or will consistently meet, its 
permit effluent concentration limits, but the percent removal 
requirements cannot be met due to less concentrated influent wastewater; 
(2) to meet the percent removal requirements, the treatment works would 
have to achieve significantly more stringent effluent concentrations 
than would otherwise be required by the concentration-based standards; 
and (3) the less concentrated influent wastewater does not result from 
either excessive infiltration or clear water industrial discharges 
during dry weather periods. The determination of whether the less 
concentrated wastewater results from excessive infiltration is discussed 
in 40 CFR 35.2005(b)(28), plus the additional criterion that either 40 
gallons per capita per day (gpcd) or 1500 gallons per inch diameter per 
mile of sewer (gpdim) may be used as the threshold value for that 
portion of the dry weather base flow attributed to infiltration. If the 
less concentrated influent wastewater is the result of clear water 
industrial discharges, then the treatment works must control such 
discharges pursuant to 40 CFR part 403.

[49 FR 37006, Sept. 20, 1984, as amended at 50 FR 23387, June 3, 1985; 
50 FR 36880, Sept. 10, 1985; 54 FR 4228, Jan. 27, 1989]



Sec. 133.104  Sampling and test procedures.

    (a) Sampling and test procedures for pollutants listed in this part 
shall be in accordance with guidelines promulgated by the Administrator 
in 40 CFR part 136.
    (b) Chemical oxygen demand (COD) or total organic carbon (TOC) may 
be substituted for BOD5 when a long-term BOD:COD or BOD:TOC 
correlation has been demonstrated.



Sec. 133.105  Treatment equivalent to secondary treatment.

    This section describes the minimum level of effluent quality 
attainable by facilities eligible for treatment equivalent to secondary 
treatment (Sec. 133.101(g)) in terms of the parameters--
BOD5, SS and pH. All requirements for the specified 
parameters in paragraphs (a), (b) and (c) of this section shall be 
achieved except as provided for in Sec. 133.103, or paragraphs (d), (e) 
or (f) of this section.
    (a) BOD5. (1) The 30-day average shall not exceed 45 mg/
l.
    (2) The 7-day average shall not exceed 65 mg/l.

[[Page 683]]

    (3) The 30-day average percent removal shall not be less than 65 
percent.
    (b) SS. Except where SS values have been adjusted in accordance with 
Sec. 133.103(c):
    (1) The 30-day average shall not exceed 45 mg/l.
    (2) The 7-day average shall not exceed 65 mg/l.
    (3) The 30-day average percent removal shall not be less than 65 
percent.
    (c) pH. The requirements of Sec. 133.102(c) shall be met.
    (d) Alternative State requirements. Except as limited by paragraph 
(f) of this section, and after notice and opportunity for public 
comment, the Regional Administrator, or, if appropriate, State Director 
subject to EPA approval, is authorized to adjust the minimum levels of 
effluent quality set forth in paragraphs (a)(1), (a)(2), (b)(1) and 
(b)(2) of this section for trickling filter facilities and in paragraphs 
(a)(1) and (a)(2) of this section for waste stabilization pond 
facilities, to conform to the BOD5 and SS effluent 
concentrations consistently achievable through proper operation and 
maintenance (Sec. 133.101(f)) by the median (50th percentile) facility 
in a representative sample of facilities within a State or appropriate 
contiguous geographical area that meet the definition of facilities 
eligible for treatment equivalent to secondary treatment (Sec. 
133.101(g)).

(The information collection requirements contained in this rule have 
been approved by OMB and assigned control number 2040-0051)

    (e) CBOD5 limitations:
    (1) Where data are available to establish CBOD5 
limitations for a treatment works subject to this section, the NPDES 
permitting authority may substitute the parameter CBOD5 for 
the parameter BOD5 In Sec. Sec. 133.105(a)(1), 133.105(a)(2) 
and 133.105(a)(3), on a case-by-case basis provided that the levels of 
CBOD5 effluent quality are not less stringent than the 
following:
    (i) The 30-day average shall not exceed 40 mg/l.
    (ii) The 7-days average shall not exceed 60 mg/l.
    (iii) The 30-day average percent removal shall not be less than 65 
percent.
    (2) Where data are available, the parameter CBOD5 may be 
used for effluent quality limitations established under paragraph (d) of 
this section. Where concurrent BOD effluent data are available, they 
must be submitted with the CBOD data as a part of the approval process 
outlined in paragraph (d) of this section.
    (f) Permit adjustments. Any permit adjustment made pursuant to this 
part may not be any less stringent than the limitations required 
pursuant to Sec. 133.105(a)-(e). Furthermore, permitting authorities 
shall require more stringent limitations when adjusting permits if: (1) 
For existing facilities the permitting authority determines that the 30-
day average and 7-day average BOD5 and SS effluent values 
that could be achievable through proper operation and maintenance of the 
treatment works, based on an analysis of the past performance of the 
treatment works, would enable the treatment works to achieve more 
stringent limitations, or
    (2) For new facilities, the permitting authority determines that the 
30-day average and 7-day average BOD5 and SS effluent values 
that could be achievable through proper operation and maintenance of the 
treatment works, considering the design capability of the treatment 
process and geographical and climatic conditions, would enable the 
treatment works to achieve more stringent limitations.
