                               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, 2023), 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 dropped in 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.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

    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.

Sec.  401.10  Scope and purpose.

    Regulations promulgated or proposed under parts 402 through 699 of 
this subchapter prescribe effluent limitations guidelines for existing 
sources, standards of performance for new sources and pretreatment 
standards for new and existing sources pursuant to sections 301, 304 (b) 
and (c), 306 (b) and (c), 307 (b) and (c) and 316(b) of the Federal 
Water Pollution Control Act, as amended (the ``Act''), 33 U.S.C. 1251, 
1311, 1314 (b) and (c), 1316 (b) and (c), 1317 (b) and (c) and 1326(b); 
86 Stat. 816; Pub. L. 92-500. Point sources of discharges of pollutants 
are required to comply with these regulations, where applicable, and 
permits issued by States or the Environmental Protection Agency (EPA) 
under the National Pollutant Discharge Elimination System (NPDES) 
established pursuant to section 402 of the Act must be conditioned upon 
compliance with applicable requirements of sections 301 and 306 (as well 
as certain other requirements). This part 401 sets forth the legal 
authority and general definitions which will apply to all regulations 
issued concerning specific classes and categories of point sources under 
parts 402 through 699 of this subchapter which follow. In certain 
instances the regulations applicable to a particular point source 
category or subcategory will contain more specialized definitions. 
Except as provided in Sec.  401.17, in the case of any conflict between 
regulations issued under this part 401 and regulations issued under 
parts 402 through 499 of this subchapter, the latter more specific 
regulations shall apply.

(Secs. 301, 304, 306 and 501 of the Clean Water Act (the Federal Water

    (a) The term Act means the Federal Water Pollution Control Act, as 
amended, 33 U.S.C. 1251 et seq., 86 Stat. 816, Pub. L. 92-500.
    (b) The term Administrator means the Administrator of the United 
States Environmental Protection Agency.
    (c) The term Environmental Protection Agency means the United States 
Environmental Protection Agency.
    (d) The term point source means any discernible, confined and 
discrete conveyance, including but not limited to any pipe, ditch, 
channel, tunnel, conduit, well, discrete fissure, container, rolling 
stock, concentrated animal feeding operation, or vessel or other 
floating craft, from which pollutants are or may be discharged.
    (e) The term new source means any building, structure, facility or 
installation from which there is or may be the discharge of pollutants, 
the construction of which is commenced after the publication of proposed 
regulations prescribing a standard of performance under section 306 of 
the Act which will be applicable to such source if such standard is 
thereafter promulgated in accordance with section 306 of the Act.
    (f) The term pollutant means dredged spoil, solid waste, incinerator 
residue, sewage, garbage, sewage sludge, munitions, chemical wastes, 
biological materials, radioactive materials, heat, wrecked or discarded 
equipment, rock,

[[Page 6]]

sand, cellar dirt and industrial, municipal and agricultural waste 
discharged into water. It does not mean (1) sewage from vessels or (2) 
water, gas or other material which is injected into a well to facilitate 
production of oil or gas, or water derived in association with oil or 
gas production and disposed of in a well, if the well, used either to 
facilitate production or for disposal purposes, is approved by authority 
of the State in which the well is located, and if such State determines 
that such injection or disposal will not result in degradation of ground 
or surface water resources.
    (g) The term pollution means the man-made or man induced alteration 
of the chemical, physical, biological and radiological integrity of 
water.
    (h) The term discharge of pollutant(s) means: (1) The addition of 
any pollutant to navigable waters from any point source and (2) any 
addition of any pollutant to the waters of the contiguous zone or the 
ocean from any point source, other than from a vessel or other floating 
craft. The term ``discharge'' includes either the discharge of a single 
pollutant or the discharge of multiple pollutants.
    (i) The term effluent limitation means any restriction established 
by the Administrator on quantities, rates, and concentrations of 
chemical, physical, biological and other constituents which are 
discharged from point sources, other than new sources, into navigable 
waters, the waters of the contiguous zone or the ocean.
    (j) The term effluent limitations guidelines means any effluent

Sec.  401.12  Law authorizing establishment of effluent limitations 
guidelines for existing sources, standards of performance for new 
sources and pretreatment standards of new and existing sources.

    (a) Section 301(a) of the Act provides that ``except as in 
compliance with this section and sections 302, 306, 307, 318, 402 and 
404 of this Act, the discharge of any pollutant by any person shall be 
unlawful.''
    (b) Section 301(b) of the Act requires the achievement by not later 
than July 1, 1977, of effluent limitations for point sources, other than 
publicly owned treatment works, which require the application of the 
best practicable control technology currently available as determined by 
the Administrator pursuant to section 304(b)(1) of the Act. Section 
301(b) also requires the achievement by not later than July 1, 1983, of 
effluent limitations for point sources, other than publicly owned 
treatment works, which require the application of the best available 
technology economically achievable which will result in reasonable 
further progress toward the national goal of eliminating the discharge 
of all pollutants, as determined in accordance with regulations issued 
by the Administrator pursuant to section 304(b)(2) of the Act.
    (c) Section 304(b) of the Act requires the Administrator to publish 
regulations providing guidelines for effluent limitations setting forth 
the degree of effluent reduction attainable through the application of 
the best practicable control technology currently available and the 
degree of effluent reduction attainable through the application of the 
best control measures and practices achievable including treatment 
techniques, process and procedure innovations, operating methods and 
other alternatives.
    (d) Section 304(c) of the Act requires the Administrator, after 
consultation with appropriate Federal and State agencies and other 
interested persons to issue information on the process, procedures, or 
operating methods which result in the elimination or reduction of the 
discharge of pollutants to implement standards of performance under 
section 306 of the Act.
    (e) Section 306(b)(1)(B) of the Act requires the Administrator, 
after a category of sources is included in a list published pursuant to 
section 306(b)(1)(A) of the Act, to propose regulations establishing 
Federal standards of performances for new sources within such category. 
Standards of performance are to provide for the control of the discharge 
of pollutants which reflect the greatest degree of effluent reduction 
which the Administrator determines to be achievable through application 
of the best available demonstrated control technology, processes, 
operating methods, or other alternatives, including, where practicable, 
a standard permitting no discharge of pollutants.
    (f) Section 307(b) provides that the Administrator shall establish 
pretreatment standards which shall prevent the discharge of any 
pollutant into publicly owned treatment works which pollutant interferes 
with, passes through untreated, or otherwise is incompatible with such 
works.
    (g) Section 307(c) of the Act provides that the Administrator shall 
promulgate pretreatment standards for sources which would be ``new 
sources'' under section 306 (if they were to discharge pollutants 
directly to navigable waters) at the same time standards of performance 
for the equivalent category of new sources are promulgated.
    (h) Section 316(b) of the Act provides that any standard established 
pursuant to section 301 or section 306 of the Act 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.

[[Page 8]]

    (i) Section 402(a)(1) of the Act provides that the Administrator may 
issue permits for the discharge of any pollutant upon condition that 
such discharge will meet all applicable requirements under sections 301, 
302, 306, 307, 308 and 403 of this Act. In addition, section 
402(b)(1)(A) of the Act requires that permits issued by States under the 
National Pollutant Discharge Elimination System (NPDES) established by 
the Act must apply, and insure compliance with any applicable 
requirements of sections 301, 302, 306, 307 and 403 of the Act.



Sec.  401.13  Test procedures for measurement.

    The test procedures for measurement which are prescribed at part 136 
of this chapter shall apply to expressions of pollutant amounts, 
characteristics or properties in effluent limitations guidelines and 
standards of performance and pretreatment standards as set forth at 
parts 402 through 699 of this subchapter, unless otherwise specifically 
noted or defined in said parts.



Sec.  401.14  Cooling water intake structures.

    The location, design, construction and capacity of cooling water 
intake structures of any point source for which a standard is 
established pursuant to section 301 or 306 of the Act shall reflect the 
best technology available for minimizing adverse environmental impact, 
in accordance with the provisions of part 402 of this chapter.

independent of an existing source at the same site. In determining 
whether these are substantially independent, factors such 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 should be considered.
    (2) Construction on a site at which an existing source is located 
results in a modification rather than a New Source if the construction 
does not create a new building, structure, facility or installation 
meeting the criteria of paragraphs (m)(1)(ii) or (m)(1)(iii) of this 
section, but otherwise alters, replaces, or adds to existing process or

discharging or otherwise introducing such pollutants into a POTW. The 
reduction or alteration may be obtained by physical, chemical or 
biological processes, process changes or by other means, except as 
prohibited by Sec.  403.6(d). Appropriate pretreatment technology 
includes control equipment, such as equalization tanks or facilities, 
for protection against surges or slug loadings that might interfere with 
or otherwise be incompatible with the POTW. However, where wastewater 
from a regulated process is mixed in an equalization facility with 
unregulated wastewater or with wastewater from another regulated 
process, the effluent from the equalization facility must meet an 
adjusted pretreatment limit calculated in accordance with Sec.  
403.6(e).

the average dry weather hydraulic or organic capacity of the POTW 
Treatment plant; or is designated as such by the Control Authority on 
the basis that the Industrial User has a reasonable potential for 
adversely affecting the POTW's operation or for violating any 
Pretreatment Standard or requirement (in accordance with 40 CFR 
403.8(f)(6)).
    (2) The Control Authority may determine that an Industrial User 
subject to categorical Pretreatment Standards

[[Page 13]]

under Sec.  403.6 and 40 CFR chapter I, subchapter N is a Non-
Significant Categorical Industrial User rather than a Significant 
Industrial User on a finding that the Industrial User never discharges 
more than 100 gallons per day (gpd) of total categorical wastewater 
(excluding sanitary, non-contact cooling and boiler blowdown wastewater, 
unless specifically included in the Pretreatment Standard) and the 
following conditions are met:
    (i) The Industrial User, prior to the Control Authority's finding, 
has consistently complied with all applicable categorical Pretreatment 
Standards and Requirements;
    (ii) The Industrial User annually submits the certification 
statement required in Sec.  403.12(q) together with any additional 
information necessary to support the certification statement; and
    (iii) The Industrial User never discharges any untreated 
concentrated wastewater.
    (3) Upon a finding that an Industrial User meeting the criteria in 
paragraph (v)(1)(ii) of this section has no reasonable potential for 
adversely affecting the POTW's operation or for violating any 
Pretreatment Standards or requirement, the Control Authority may at any 
time, on its own initiative or in response to a petition received from 
an Industrial User or POTW, and in accordance with 40 CFR 403.8(f)(6), 
determine that such Industrial User is not a Significant Industrial 
User.
    (w) The term Submission means:
    (1) A request by a POTW for approval of a Pretreatment Program to 
the EPA or a Director;
    (2) A request by a POTW to the EPA or a Director for authority to 
revise the discharge limits in categorical Pretreatment Standards to 
reflect POTW pollutant removals; or
    (3) A request to the EPA by an NPDES State for approval of its State 
pretreatment program.

Sec.  403.4  State or local law.

    Nothing in this regulation is intended to affect any Pretreatment 
Requirements, including any standards or prohibitions, established by 
State or local law as long as the State or local requirements are not 
less stringent than any set forth in National Pretreatment Standards, or 
any other requirements or prohibitions established under the Act or this 
regulation. States with an NPDES permit program approved in accordance 
with section 402 (b) and (c) of the Act, or States requesting NPDES 
programs, are responsible for developing a State pretreatment program in 
accordance with Sec.  403.10 of this regulation.



Sec.  403.5  National pretreatment standards: Prohibited discharges.

    (a)(1) General prohibitions. A User may not introduce into a POTW 
any pollutant(s) which cause Pass Through or Interference. These general 
prohibitions and the specific prohibitions in paragraph (b) of this 
section apply to each User introducing pollutants into a POTW whether or 
not the User is subject to other National Pretreatment Standards or any 
national, State, or local Pretreatment Requirements.
    (2) Affirmative Defenses. A User shall have an affirmative defense 
in any action brought against it alleging a violation of the general 
prohibitions established in paragraph (a)(1) of this section and the 
specific prohibitions in paragraphs (b)(3), (b)(4), (b)(5), (b)(6), and 
(b)(7) of this section where the User can demonstrate that:
    (i) It did not know or have reason to know that its Discharge, alone 
or in conjunction with a discharge or discharges from other sources, 
would cause Pass Through or Interference; and
    (ii)(A) A local limit designed to prevent Pass Through and/or 
Interference, as the case may be, was developed in accordance with 
paragraph (c) of this section for each pollutant in the User's Discharge 
that caused Pass Through or Interference, and the User was in compliance 
with each such local limit directly prior to and during the Pass Through 
or Interference; or
    (B) If a local limit designed to prevent Pass Through and/or 
Interference,

[[Page 14]]

as the case may be, has not been developed in accordance with paragraph 
(c) of this section for the pollutant(s) that caused the Pass Through or 
Interference, the User's Discharge directly prior to and during the Pass 
Through or Interference did not change substantially in nature or 
constituents from the User's prior discharge activity when the POTW was 
regularly in compliance with the POTW's NPDES permit requirements and, 
in the case of Interference, applicable requirements for sewage sludge 
use or disposal.
    (b) Specific prohibitions. In addition, the following pollutants 
shall not be introduced into a POTW:
    (1) Pollutants which create a fire or explosion hazard in the POTW, 
including, but not limited to, wastestreams with a closed cup flashpoint 
of less than 140 degrees Fahrenheit or 60 degrees Centigrade using the 
test methods specified in 40 CFR 261.21;
    (2) Pollutants which will cause corrosive structural damage to the 
POTW, but in no case Discharges with pH lower than 5.0, unless the works 
is specifically designed to accommodate such Discharges;
    (3) Solid or viscous pollutants in amounts which will cause 
obstruction to the flow in the POTW resulting in Interference;
    (4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) 
released in a Discharge at a flow rate and/or pollutant concentration 
which will cause Interference with the POTW.
    (5) Heat in amounts which will inhibit biological activity in the 
POTW resulting in Interference, but in no case heat in such quantities 
that the temperature at the POTW Treatment Plant exceeds 40 [deg]C (104 
[deg]F) unless the Approval Authority, upon request of the POTW, 
approves alternate temperature limits.
    (6) Petroleum oil, nonbiodegradable cutting oil, or products of 
mineral oil origin in amounts that will cause interference or pass 
through;
    (7) Pollutants which result in the presence of toxic gases, vapors, 
or fumes within the POTW in a quantity that may cause acute worker 
health and safety problems;
    (8) Any trucked or hauled pollutants, except at discharge points 
designated by the POTW.
    (c) When specific limits must be developed by POTW. (1) Each POTW 
developing a POTW Pretreatment Program pursuant to Sec.  403.8 shall 
develop and enforce specific limits to implement the prohibitions listed 
in paragraphs (a)(1) and (b) of this section. Each POTW with an approved 
pretreatment program shall continue to develop these limits as necessary 
and effectively enforce such limits.
    (2) All other POTW's shall, in cases where pollutants contributed by 
User(s) result in Interference or Pass-Through, and such violation is 
likely to recur, develop and enforce specific effluent limits for 
Industrial User(s), and all other users, as appropriate, which, together 
with appropriate changes in the POTW Treatment Plant's facilities or 
operation, are necessary to ensure renewed and continued compliance with 
the POTW's NPDES permit or sludge use or disposal practices.
    (3) Specific effluent limits shall not be developed and enforced 
without individual notice to persons or groups who have requested such 
notice and an opportunity to respond.
    (4) POTWs may develop Best Management Practices (BMPs) to implement 
paragraphs (c)(1) and (c)(2) of this section. Such BMPs shall be 
considered local limits and Pretreatment Standards for the purposes of 
this part and section 307(d) of the Act.
    (d) Local limits. Where specific prohibitions or limits on 
pollutants or pollutant parameters are developed by a POTW in accordance 
with paragraph (c) above, such limits shall be deemed Pretreatment 
Standards for the purposes of section 307(d) of the Act.
    (e) EPA enforcement actions under section 309(f) of the Clean Water 
Act.
    If, within 30 days after notice of an Interference or Pass Through 
violation has been sent by EPA to the POTW, and to persons or groups who 
have requested such notice, the POTW fails to commence appropriate 
enforcement action to correct the violation, EPA may take appropriate 
enforcement action

[[Page 15]]

under the authority provided in section 309(f) of the Clean Water Act.

Sec.  403.6  National pretreatment standards: Categorical standards.

    National pretreatment standards specifying quantities or 
concentrations of pollutants or pollutant properties which may be 
discharged to a POTW by existing or new industrial users in specific 
industrial subcategories will be established as separate regulations 
under the appropriate subpart of 40 CFR chapter I, subchapter N. These 
standards, unless specifically noted otherwise, shall be in addition to 
all applicable pretreatment standards and requirements set forth in this 
part.
    (a) Category determination request--(1) Application deadline. Within 
60 days after the effective date of a Pretreatment Standard for a 
subcategory under which an Industrial User may be included, the 
Industrial User or POTW may request that the Water Management Division 
Director or Director, as appropriate, provide written certification on 
whether the Industrial User falls within that particular subcategory. If 
an existing Industrial User adds or changes a process or operation which 
may be included in a subcategory, the existing Industrial User must 
request this certification prior to commencing discharge from the added 
or changed processes or operation. A New Source must request this 
certification prior to commencing discharge. Where a request for 
certification is submitted by a POTW, the POTW shall notify any affected 
Industrial User of such submission. The Industrial User may provide 
written comments on the POTW submission to the Water Management Division 
Director or Director, as appropriate, within 30 days of notification.
    (2) Contents of application. Each request shall contain a statement:
    (i) Describing which subcategories might be applicable; and
    (ii) Citing evidence and reasons why a particular subcategory is 
applicable and why others are not applicable. Any person signing the 
application statement submitted pursuant to this section shall make the 
following certification:

    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 gather and evaluate the information submitted. Based on my 
inquiry of the person or persons who manage the system, or those persons 
directly responsible for gathering the information, the information 
submitted is, to the best of my knowledge and belief, true, accurate, 
and complete. I am aware that there are significant penalties for 
submitting false information, including the possibility of fine and 
imprisonment for knowing violations.

    (3) Deficient requests. The Water Management Division Director or 
Director will only act on written requests for determinations that 
contain all of the information required. Persons who have made 
incomplete submissions will be notified by the Water Management Division 
Director or Director that their requests are deficient and, unless the 
time period is extended, will be given 30 days to correct the 
deficiency. If the deficiency is not corrected within 30 days or within 
an extended period allowed by the Water Management Division Director or 
the Director, the request for a determination shall be denied.
    (4) Final decision. (i) When the Water Management Division Director 
or Director receives a submittal he or she will, after determining that 
it contains all of the information required by paragraph (2) of this 
section, consider the submission, any additional evidence that may have 
been requested, and any other available information relevant to the 
request. The Water Management Division Director or Director will then 
make a written determination of the applicable subcategory and state the 
reasons for the determination.
    (ii) Where the request is submitted to the Director, the Director 
shall forward the determination described in this paragraph to the Water 
Management Division Director who may make a final determination. The 
Water Management Division Director may waive receipt of these 
determinations. If the Water Management Division Director does not 
modify the Director's decision within 60 days after receipt thereof, or

[[Page 16]]

if the Water Management Division Director waives receipt of the 
determination, the Director's decision is final.
    (iii) Where the request is submitted by the Industrial User or POTW 
to the Water Management Division Director or where the Water Management 
Division Director elects to modify the Director's decision, the Water 
Management Division Director's decision will be final.
    (iv) The Water Management Division Director or Director, as 
appropriate, shall send a copy of the determination to the affected 
Industrial User and the POTW. Where the final determination is made by 
the Water Management Division Director, he or she shall send a copy of 
the determination to the Director.
    (5) Requests for hearing and/or legal decision. Within 30 days 
following the date of receipt of notice of the final determination as 
provided for by paragraph (a)(4)(iv) of this section, the Requester may 
submit a petition to reconsider or contest the decision to the Regional 
Administrator who shall act on such petition expeditiously and state the 
reasons for his or her determination in writing.
    (b) Deadline for compliance with categorical standards. Compliance 
by existing sources with categorical Pretreatment Standards shall be 
within 3 years of the date the Standard is effective unless a shorter 
compliance time is specified in the appropriate subpart of 40 CFR 
chapter I, subchapter N. Direct dischargers with NPDES Permits modified 
or reissued to provide a variance pursuant to section 301(i)(2) of the 
Act shall be required to meet compliance dates set in any applicable 
categorical Pretreatment Standard. Existing sources which become 
Industrial Users subsequent to promulgation of an applicable categorical 
Pretreatment Standard shall be considered existing Industrial Users 
except where such sources meet the definition of a New Source as defined 
in Sec.  403.3(m). New Sources shall install and have in operating 
condition, and shall ``start-up'' all pollution control equipment 
required to meet applicable Pretreatment Standards before beginning to 
Discharge. Within the shortest feasible time (not to exceed 90 days), 
New Sources must meet all applicable Pretreatment Standards.
    (c)(1) Concentration and mass limits. Pollutant discharge limits in 
categorical Pretreatment Standards will be expressed either as 
concentration or mass limits. Wherever possible, where concentration 
limits are specified in standards, equivalent mass limits will be 
provided so that local, State or Federal authorities responsible for 
enforcement may use either concentration or mass limits. Limits in 
categorical Pretreatment Standards shall apply to the effluent of the 
process regulated by the Standard, or as otherwise specified by the 
standard.
    (2) When the limits in a categorical Pretreatment Standard are 
expressed only in terms of mass of pollutant per unit of production, the 
Control Authority may convert the limits to equivalent limitations 
expressed either as mass of pollutant discharged per day or effluent 
concentration for purposes of calculating effluent limitations 
applicable to individual Industrial Users.
    (3) A Control Authority calculating equivalent mass-per-day 
limitations under paragraph (c)(2) of this section shall calculate such 
limitations by multiplying the limits in the Standard by the Industrial 
User's average rate of production. This average rate of production shall 
be based not upon the designed production capacity but rather upon a 
reasonable measure of the Industrial User's actual long-term daily 
production, such as the average daily production during a representative 
year. For new sources, actual production shall be estimated using 
projected production.
    (4) A Control Authority calculating equivalent concentration 
limitations under paragraph (c)(2) of this section shall calculate such 
limitations by dividing the mass limitations derived under paragraph 
(c)(3) of this section by the average daily flow rate of the Industrial 
User's regulated process wastewater. This average daily flow rate shall 
be based upon a reasonable measure of the Industrial User's actual long-
term average flow rate, such as the average daily flow rate during the 
representative year.
    (5) When the limits in a categorical Pretreatment Standard are 
expressed

[[Page 17]]

only in terms of pollutant concentrations, an Industrial User may 
request that the Control Authority convert the limits to equivalent mass 
limits. The determination to convert concentration limits to mass limits 
is within the discretion of the Control Authority. The Control Authority 
may establish equivalent mass limits only if the Industrial User meets 
all the following conditions in paragraph (c)(5)(i)(A) through 
(c)(5)(i)(E) of this section.
    (i) To be eligible for equivalent mass limits, the Industrial User 
must:
    (A) Employ, or demonstrate that it will employ, water conservation 
methods and technologies that substantially reduce water use during the 
term of its control mechanism;
    (B) Currently use control and treatment technologies adequate to 
achieve compliance with the applicable categorical Pretreatment 
Standard, and not have used dilution as a substitute for treatment;
    (C) Provide sufficient information to establish the facility's 
actual average daily flow rate for all wastestreams, based on data from 
a continuous effluent flow monitoring device, as well as the facility's 
long-term average production rate. Both the actual average daily flow 
rate and long-term average production rate must be representative of 
current operating conditions;
    (D) Not have daily flow rates, production levels, or pollutant 
levels that vary so significantly that equivalent mass limits are not 
appropriate to control the Discharge; and
    (E) Have consistently complied with all applicable categorical 
Pretreatment Standards during the period prior to the Industrial User's 
request for equivalent mass limits.
    (ii) An Industrial User subject to equivalent mass limits must:
    (A) Maintain and effectively operate control and treatment 
technologies adequate to achieve compliance with the equivalent mass 
limits;
    (B) Continue to record the facility's flow rates through the use of 
a continuous effluent flow monitoring device;
    (C) Continue to record the facility's production rates and notify 
the Control Authority whenever production rates are expected to vary by 
more than 20 percent from its baseline production rates determined in 
paragraph (c)(5)(i)(C) of this section. Upon notification of a revised 
production rate, the Control Authority must reassess the equivalent mass 
limit and revise the limit as necessary to reflect changed conditions at 
the facility; and
    (D) Continue to employ the same or comparable water conservation 
methods and technologies as those implemented pursuant to paragraph 
(c)(5)(i)(A) of this section so long as it discharges under an 
equivalent mass limit.
    (iii) A Control Authority which chooses to establish equivalent mass 
limits:
    (A) Must calculate the equivalent mass limit by multiplying the 
actual average daily flow rate of the regulated process(es) of the 
Industrial User by the concentration-based daily maximum and monthly 
average Standard for the applicable categorical Pretreatment Standard 
and the appropriate unit conversion factor;
    (B) Upon notification of a revised production rate, must reassess 
the equivalent mass limit and recalculate the limit as necessary to 
reflect changed conditions at the facility; and
    (C) May retain the same equivalent mass limit in subsequent control 
mechanism terms if the Industrial User's actual average daily flow rate 
was reduced solely as a result of the implementation of water 
conservation methods and technologies, and the actual average daily flow 
rates used in the original calculation of the equivalent mass limit were 
not based on the use of dilution as a substitute for treatment pursuant 
to paragraph (d) of this section. The Industrial User must also be in 
compliance with Sec.  403.17 (regarding the prohibition of bypass).
    (iv) The Control Authority may not express limits in terms of mass 
for pollutants such as pH, temperature, radiation, or other pollutants 
which cannot appropriately be expressed as mass.
    (6) The Control Authority may convert the mass limits of the 
categorical Pretreatment Standards at 40 CFR parts 414, 419, and 455 to 
concentration limits for purposes of calculating limitations applicable 
to individual Industrial Users under the following conditions. When 
converting such limits to

[[Page 18]]

concentration limits, the Control Authority must use the concentrations 
listed in the applicable subparts of 40 CFR parts 414, 419, and 455 and 
document that dilution is not being substituted for treatment as 
prohibited by paragraph (d) of this section.
    (7) Equivalent limitations calculated in accordance with paragraphs 
(c)(3), (c)(4), (c)(5) and (c)(6) of this section are deemed 
Pretreatment Standards for the purposes of section 307(d) of the Act and 
this part. The Control Authority must document how the equivalent limits 
were derived and make this information publicly available. Once 
incorporated into its control mechanism, the Industrial User must comply 
with the equivalent limitations in lieu of the promulgated categorical 
standards from which the equivalent limitations were derived.
    (8) Many categorical Pretreatment Standards specify one limit for 
calculating maximum daily discharge limitations and a second limit for 
calculating maximum monthly average, or 4-day average, limitations. 
Where such Standards are being applied, the same production or flow 
figure shall be used in calculating both the average and the maximum 
equivalent limitation.
    (9) Any Industrial User operating under a control mechanism 
incorporating equivalent mass or concentration limits calculated from a 
production based standard shall notify the Control Authority within two 
(2) business days after the User has a reasonable basis to know that the 
production level will significantly change within the next calendar 
month. Any User not notifying the Control Authority of such anticipated 
change will be required to meet the mass or concentration limits in its 
control mechanism that were based on the original estimate of the long 
term average production rate.
    (d) Dilution prohibited as substitute for treatment. Except where 
expressly authorized to do so by an applicable Pretreatment Standard or 
Requirement, no Industrial User shall ever increase the use of process 
water, or in any other way attempt to dilute a Discharge as a partial or 
complete substitute for adequate treatment to achieve compliance with a 
Pretreatment Standard or Requirement. The Control Authority may impose 
mass limitations on Industrial Users which are using dilution to meet 
applicable Pretreatment Standards or Requirements, or in other cases 
where the imposition of mass limitations is appropriate.
    (e) Combined wastestream formula. Where process effluent is mixed 
prior to treatment with wastewaters other than those generated by the 
regulated process, fixed alternative discharge limits may be derived by 
the Control Authority or by the Industrial User with the written 
concurrence of the Control Authority. These alternative limits shall be 
applied to the mixed effluent. When deriving alternative categorical 
limits, the Control Authority or Industrial User shall calculate both an 
alternative daily maximum value using the daily maximum value(s) 
specified in the appropriate categorical Pretreatment Standard(s) and an 
alternative consecutive sampling day average value using the monthly 
average value(s) specified in the appropriate categorical Pretreatment 
Standard(s). The Industrial User shall comply with the alternative daily 
maximum and monthly average limits fixed by the Control Authority until 
the Control Authority modifies the limits or approves an Industrial User 
modification request. Modification is authorized whenever there is a 
material or significant change in the values used in the calculation to 
fix alternative limits for the regulated pollutant. An Industrial User 
must immediately report any such material or significant change to the 
Control Authority. Where appropriate new alternative categorical limits 
shall be calculated within 30 days.
    (1) Alternative limit calculation. For purposes of these formulas, 
the ``average daily flow'' means a reasonable measure of the average 
daily flow for a 30-day period. For new sources, flows shall be 
estimated using projected values. The alternative limit for a specified 
pollutant will be derived by the use of either of the following 
formulas:
    (i) Alternative concentration limit.

          provided, however, that where such streams contain a 
          significant amount of a pollutant, and the combination of such 
          streams, prior to treatment, with an Industrial User's 
          regulated process wastestream(s) will result in a substantial 
          reduction of that pollutant, the Control Authority, upon 
          application of the Industrial User, may exercise its 
          discretion to determine whether such stream(s) should be 
          classified as diluted or unregulated. In its application to 
          the Control Authority, the Industrial User must provide 
          engineering, production, sampling and analysis and such other 
          information so that the Control Authority can make its 
          determination; or (b) sanitary wastestreams where such streams 
          are not regulated by a Categorical Pretreatment Standard; or 
          (c) from any process wastestreams which were or could have 
          been entirely exempted from categorical Pretreatment Standards 
          pursuant to paragraph 8 of the NRDC v. Costle Consent Decree 
          (12 ERC 1833) for one or more of the following reasons (see 
          appendix D of this part):
    (1) The pollutants of concern are not detectable in the effluent 
from the Industrial User (paragraph (8)(a)(iii));
    (2) The pollutants of concern are present only in trace amounts and 
are neither causing nor likely to cause toxic effects (paragraph 
(8)(a)(iii));
    (3) The pollutants of concern are present in amounts too small to be 
effectively reduced by technologies known to the Administrator 
(paragraph (8)(a)(iii)); or
    (4) The wastestream contains only pollutants which are compatible 
with the POTW (paragraph (8)(b)(i)).
FT = The average daily flow (at least a 30-day average) 
          through the combined treatment facility (includes 
          Fi, FD and unregulated streams).
N = The total number of regulated streams.

    (ii) Alternative mass limit.

where

MT = the alternative mass limit for a pollutant in the 
          combined wastestream.
Mi = the categorical Pretreatment Standard mass limit for a 
          pollutant in the regulated stream i (the categorical 
          pretreatment mass limit multiplied by the appropriate measure

          (a) Boiler blowdown streams, non-contact cooling streams, 
          stormwater streams, and demineralizer backwash streams; 
          provided, however, that where such streams contain a 
          significant amount of a pollutant, and the combination of such 
          streams, prior to treatment, with an Industrial User's 
          regulated process wastestream(s) will result in a substantial 
          reduction of that pollutant, the Control Authority, upon 
          application of the Industrial User, may exercise its 
          discretion to determine whether such stream(s) should be 
          classified as diluted or unregulated. In its application to 
          the Control Authority, the Industrial User must provide 
          engineering, production, sampling and analysis and such other 
          information so that the Control Authority can make its 
          determination; or (b) sanitary wastestreams where such streams 
          are not regulated by a categorical Pretreatment Standard; or 
          (c) from any process wastestreams which were or could have 
          been entirely exempted from categorical Pretreatment Standards 
          pursuant to paragraph 8 of the NRDC v. Costle Consent Decree 
          (12 ERC 1833) for one or more of the following reasons (see 
          appendix D of this part):
    (1) The pollutants of concern are not detectable in the effluent 
from the Industrial User (paragraph (8)(a)(iii));
    (2) The pollutants of concern are present only in trace amounts and 
are neither causing nor likely to cause toxic effects (paragraph 
(8)(a)(iii));
    (3) The pollutants of concern are present in amounts too small to be 
effectively reduced by technologies known to the Administrator 
(paragraph (8)(a)(iii)); or

    (4) The wastestream contains only pollutants which are compatible 
with the POTW (paragraph (8)(b)(i)).
FT = The average flow (at least a 30-day average) through the 
          combined treatment facility (includes Fi, 
          FD and unregulated streams).
N = The total number of regulated streams.

    (2) Alternate limits below detection limit. An alternative 
pretreatment limit may not be used if the alternative limit is below the 
analytical detection limit for any of the regulated pollutants.
    (3) Self-monitoring. Self-monitoring required to insure compliance 
with the alternative categorical limit shall be conducted in accordance 
with the requirements of Sec.  403.12(g).
    (4) Choice of monitoring location. Where a treated regulated process 
wastestream is combined prior to treatment with wastewaters other than 
those generated by the regulated process, the Industrial User may 
monitor either the segregated process wastestream or the combined 
wastestream for the purpose of determining compliance with applicable 
Pretreatment Standards. If the Industrial User chooses to monitor the 
segregated process wastestream, it shall apply the applicable 
categorical Pretreatment Standard. If the User chooses to monitor the 
combined wastestream, it shall apply an alternative discharge limit 
calculated using the combined wastestream formula as provided in this 
section. The Industrial User may change monitoring points only after 
receiving approval from the Control Authority. The Control Authority 
shall ensure that any change in an Industrial User's monitoring point(s) 
will not allow the User to substitute dilution for adequate treatment to 
achieve compliance with applicable Standards.

Sec.  403.7  Removal credits.

    (a) Introduction--(1) Definitions. For the purpose of this section:
    (i) Removal means a reduction in the amount of a pollutant in the 
POTW's effluent or alteration of the nature of a pollutant during 
treatment at the POTW. The reduction or alteration can be obtained by 
physical, chemical or biological means and may be the result of 
specifically designed POTW capabilities or may be incidental to the 
operation of the treatment system. Removal as used in this subpart shall 
not mean dilution of a pollutant in the POTW.
    (ii) Sludge requirements shall mean the following statutory 
provisions and regulations or permits issued thereunder (or more 
stringent State or local regulations): Section 405 of the Clean Water 
Act; the Solid Waste Disposal Act (SWDA) (including title II more 
commonly referred to as the Resource Conservation Recovery Act (RCRA) 
and State regulations contained in any State sludge management plan 
prepared pursuant to subtitle D of SWDA); the Clean Air Act; the Toxic 
Substances Control Act; and the Marine Protection, Research and 
Sanctuaries Act.
    (2) General. Any POTW receiving wastes from an Industrial User to 
which a categorical Pretreatment Standard(s) applies may, at its 
discretion and subject to the conditions of this section, grant removal 
credits to reflect removal by the POTW of pollutants specified in the 
categorical Pretreatment Standard(s). The POTW may grant a removal 
credit equal to or, at its discretion, less than its consistent removal 
rate. Upon being granted a removal credit, each affected Industrial User 
shall calculate its revised discharge limits in accordance with 
paragraph (a)(4) of this section. Removal credits may only be given for 
indicator or surrogate pollutants regulated in a categorical 
Pretreatment Standard if the categorical Pretreatment Standard so 
specifies.
    (3) Conditions for authorization to give removal credits. A POTW is 
authorized to give removal credits only if the following conditions are 
met:
    (i) Application. The POTW applies for, and receives, authorization 
from the Approval Authority to give a removal credit in accordance with 
the requirements and procedures specified in paragraph (e) of this 
section.

[[Page 21]]

    (ii) Consistent removal determination. The POTW demonstrates and 
continues to achieve consistent removal of the pollutant in accordance 
with paragraph (b) of this section.
    (iii) POTW local pretreatment program. The POTW has an approved 
pretreatment program in accordance with and to the extent required by 
part 403; provided, however, a POTW which does not have an approved 
pretreatment program may, pending approval of such a program, 
conditionally give credits as provided in paragraph (d) of this section.
    (iv) Sludge requirements. The granting of removal credits will not 
cause the POTW to violate the local, State and Federal Sludge 
Requirements which apply to the sludge management method chosen by the 
POTW. Alternatively, the POTW can demonstrate to the Approval Authority 
that even though it is not presently in compliance with applicable 
Sludge Requirements, it will be in compliance when the Industrial 
User(s) to whom the removal credit would apply is required to meet its 
categorical Pretreatment Standard(s) as modified by the removal credit. 
If granting removal credits forces a POTW to incur greater sludge 
management costs than would be incurred in the absence of granting 
removal credits, the additional sludge management costs will not be 
eligible for EPA grant assistance. Removal credits may be made available 
for the following pollutants.
    (A) For any pollutant listed in appendix G section I of this part 
for the use or disposal practice employed by the POTW, when the 
requirements in 40 CFR part 503 for that practice are met.
    (B) For any pollutant listed in appendix G section II of this part 
for the use or disposal practice employed by the POTW when the 
concentration for a pollutant listed in appendix G section II of this 
part in the sewage sludge that is used or disposed does not exceed the 
concentration for the pollutant in appendix G section II of this part.
    (C) For any pollutant in sewage sludge when the POTW disposes all of 
its sewage sludge in a municipal solid waste landfill unit that meets 
the criteria in 40 CFR part 258.
    (v) NPDES permit limitations. The granting of removal credits will 
not cause a violation of the POTW's permit limitations or conditions. 
Alternatively, the POTW can demonstrate to the Approval Authority that 
even though it is not presently in compliance with applicable 
limitations and conditions in its NPDES permit, it will be in compliance 
when the Industrial User(s) to whom the removal credit would apply is 
required to meet its categorical Pretreatment Standard(s), as modified 
by the removal credit provision.
    (4) Calculation of revised discharge limits. Revised discharge 
limits for a specific pollutant shall be derived by use of the following 
formula:
[GRAPHIC] [TIFF OMITTED] TC15NO91.014

where:

x = pollutant discharge limit specified in the applicable categorical 
          Pretreatment Standard
r = removal credit for that pollutant as established under paragraph (b) 
          of this section (percentage removal expressed as a proportion, 
          i.e., a number between 0 and 1)
y = revised discharge limit for the specified pollutant (expressed in 
          same units as x)

    (b) Establishment of removal credits; demonstration of Consistent 
Removal--(1) Definition of Consistent Removal. ``Consistent Removal'' 
shall mean the average of the lowest 50 percent of the removal measured 
according to paragraph (b)(2) of this section. All sample data obtained 
for the measured pollutant during the time period prescribed in 
paragraph (b)(2) of this section must be reported and used in computing 
Consistent Removal. If a substance is measurable in the influent but not 
in the effluent, the effluent level may be assumed to be the limit of 
measurement, and those data may be used by the POTW at its discretion 
and subject to approval by the Approval Authority. If the substance is 
not measurable in the influent, the date may not be used. Where the 
number of samples with concentrations equal to or above the limit of 
measurement is between 8 and 12, the average of the lowest 6 removals 
shall be used. If there are less than 8 samples with concentrations 
equal to

[[Page 22]]

or above the limit of measurement, the Approval Authority may approve 
alternate means for demonstrating Consistent Removal. The term 
``measurement'' refers to the ability of the analytical method or 
protocol to quantify as well as identify the presence of the substance 
in question.
    (2) Consistent Removal data. Influent and effluent operational data 
demonstrating Consistent Removal or other information, as provided for 
in paragraph (b)(1) of this section, which demonstrates Consistent 
Removal of the pollutants for which discharge limit revisions are 
proposed. This data shall meet the following requirements:
    (i) Representative data; seasonal. The data shall be representative 
of yearly and seasonal conditions to which the POTW is subjected for 
each pollutant for which a discharge limit revision is proposed.
    (ii) Representative data; quality and quantity. The data shall be 
representative of the quality and quantity of normal effluent and 
influent flow if such data can be obtained. If such data are 
unobtainable, alternate data or information may be presented for 
approval to demonstrate Consistent Removal as provided for in paragraph 
(b)(1) of this section.
    (iii) Sampling procedures: Composite. (A) The influent and effluent 
operational data shall be obtained through 24-hour flow-proportional 
composite samples. Sampling may be done manually or automatically, and 
discretely or continuously. For discrete sampling, at least 12 aliquots 
shall be composited. Discrete sampling may be flow-proportioned either 
by varying the time interval between each aliquot or the volume of each 
aliquot. All composites must be flow-proportional to each stream flow at 
time of collection of influent aliquot or to the total influent flow 
since the previous influent aliquot. Volatile pollutant aliquots must be 
combined in the laboratory immediately before analysis.
    (B)(1) Twelve samples shall be taken at approximately equal 
intervals throughout one full year. Sampling must be evenly distributed 
over the days of the week so as to include no-workdays as well as 
workdays. If the Approval Authority determines that this schedule will 
not be most representative of the actual operation of the POTW Treatment 
Plant, an alternative sampling schedule will be approved.
    (2) In addition, upon the Approval Authority's concurrence, a POTW 
may utilize an historical data base amassed prior to the effective data 
of this section provide that such data otherwise meet the requirements 
of this paragraph. In order for the historical data base to be approved 
it must present a statistically valid description of daily, weekly and 
seasonal sewage treatment plant loadings and performance for at least 
one year.
    (C) Effluent sample collection need not be delayed to compensate for 
hydraulic detention unless the POTW elects to include detention time 
compensation or unless the Approval Authority requires detention time 
compensation. The Approval Authority may require that each effluent 
sample be taken approximately one detention time later than the 
corresponding influent sample when failure to do so would result in an 
unrepresentative portrayal of actual POTW operation. The detention 
period is to be based on a 24-hour average daily flow value. The average 
daily flow used will be based upon the average of the daily flows during 
the same month of the previous year.
    (iv) Sampling procedures: Grab. Where composite sampling is not an 
appropriate sampling technique, a grab sample(s) shall be taken to 
obtain influent and effluent operational data. Collection of influent 
grab samples should precede collection of effluent samples by 
approximately one detention period. The detention period is to be based 
on a 24-hour average daily flow value. The average daily flow used will 
be based upon the average of the daily flows during the same month of 
the previous year. Grab samples will be required, for example, where the 
parameters being evaluated are those, such as cyanide and phenol, which 
may not be held for any extended period because of biological, chemical 
or physical interactions which take place after sample collection and 
affect the results. A grab sample is an individual sample collected

[[Page 23]]

over a period of time not exceeding 15 minutes.
    (v) Analytical methods. The sampling referred to in paragraphs 
(b)(2) (i) through (iv) of this section and an analysis of these samples 
shall be performed in accordance with the techniques prescribed in 40 
CFR part 136 and amendments thereto. Where 40 CFR part 136 does not 
contain sampling or analytical techniques for the pollutant in question, 
or where the Administrator determines that the part 136 sampling and 
analytical techniques are inappropriate for the pollutant in question, 
sampling and analysis shall be performed using validated analytical 
methods or any other applicable sampling and analytical procedures, 
including procedures suggested by the POTW or other parties, approved by 
the Administrator.
    (vi) Calculation of removal. All data acquired under the provisions 
of this section must be submitted to the Approval Authority. Removal for 
a specific pollutant shall be determined either, for each sample, by 
measuring the difference between the concentrations of the pollutant in 
the influent and effluent of the POTW and expressing the difference as a 
percent of the influent concentration, or, where such data cannot be 
obtained, Removal may be demonstrated using other data or procedures 
subject to concurrence by the Approval Authority as provided for in 
paragraph (b)(1) of this section.
    (c) Provisional credits. For pollutants which are not being 
discharged currently (i.e., new or modified facilities, or production 
changes) the POTW may apply for authorization to give removal credits 
prior to the initial discharge of the pollutant. Consistent removal 
shall be based provisionally on data from treatability studies or 
demonstrated removal at other treatment facilities where the quality and 
quantity of influent are similar. Within 18 months after the 
commencement of discharge of pollutants in question, consistent removal 
must be demonstrated pursuant to the requirements of paragraph (b) of 
this section. If, within 18 months after the commencement of the 
discharge of the pollutant in question, the POTW cannot demonstrate 
consistent removal pursuant to the requirements of paragraph (b) of this 
section, the authority to grant provisional removal credits shall be 
terminated by the Approval Authority and all Industrial Users to whom 
the revised discharge limits had been applied shall achieve compliance 
with the applicable categorical Pretreatment Standard(s) within a 
reasonable time, not to exceed the period of time prescribed in the 
applicable categorical Pretreatment Standard(s), as may be specified by 
the Approval Authority.
    (d) Exception to POTW Pretreatment Program Requirement. A POTW 
required to develop a local pretreatment program by Sec.  403.8 may 
conditionally give removal credits pending approval of such a program in 
accordance with the following terms and conditions:
    (1) All Industrial Users who are currently subject to a categorical 
Pretreatment Standard and who wish conditionally to receive a removal 
credit must submit to the POTW the information required in Sec.  
403.12(b)(1) through (7) (except new or modified industrial users must 
only submit the information required by Sec.  403.12(b)(1) through (6)), 
pertaining to the categorical Pretreatment Standard as modified by the 
removal credit. The Industrial Users shall indicate what additional 
technology, if any, will be needed to comply with the categorical 
Pretreatment Standard(s) as modified by the removal credit;
    (2) The POTW must have submitted to the Approval Authority an 
application for pretreatment program approval meeting the requirements 
of Sec. Sec.  403.8 and 403.9 in a timely manner, not to exceed the time 
limitation set forth in a compliance schedule for development of a 
pretreatment program included in the POTW's NPDES permit, but in no case 
later than July 1, 1983, where no permit deadline exists;
    (3) The POTW must:
    (i) Compile and submit data demonstrating its consistent removal in 
accordance with paragraph (b) of this section;
    (ii) Comply with the conditions specified in paragraph (a)(3) of 
this section; and
    (iii) Submit a complete application for removal credit authority in 
accordance with paragraph (e) of this section;

[[Page 24]]

    (4) If a POTW receives authority to grant conditional removal 
credits and the Approval Authority subsequently makes a final 
determination, after appropriate notice, that the POTW failed to comply 
with the conditions in paragraphs (d)(2) and (3) of this section, the 
authority to grant conditional removal credits shall be terminated by 
the Approval Authority and all Industrial Users to whom the revised 
discharge limits had been applied shall achieve compliance with the 
applicable categorical Pretreatment Standard(s) within a reasonable 
time, not to exceed the period of time prescribed in the applicable 
categorical Pretreatment Standard(s), as may be specified by the 
Approval Authority.
    (5) If a POTW grants conditional removal credits and the POTW or the 
Approval Authority subsequently makes a final determination, after 
appropriate notice, that the Industrial User(s) failed to comply with 
the conditions in paragraph (d)(1) of this section, the conditional 
credit shall be terminated by the POTW or the Approval Authority for the 
non-complying Industrial User(s) and the Industrial User(s) to whom the 
revised discharge limits had been applied shall achieve compliance with 
the applicable categorical Pretreatment Standard(s) within a reasonable 
time, not to exceed the period of time prescribed in the applicable 
categorical Pretreatment Standard(s), as may be specified by the 
Approval Authority. The conditional credit shall not be terminated where 
a violation of the provisions of this paragraph results from causes 
entirely outside of the control of the Industrial User(s) or the 
Industrial User(s) had demonstrated substantial compliance.
    (6) The Approval Authority may elect not to review an application 
for conditional removal credit authority upon receipt of such 
application, in which case the conditionally revised discharge limits 
will remain in effect until reviewed by the Approval Authority. This 
review may occur at any time in accordance with the procedures of Sec.  
403.11, but in no event later than the time of any pretreatment program 
approval or any NPDES permit reissuance thereunder.
    (e) POTW application for authorization to give removal credits and 
Approval Authority review--(1) Who must apply. Any POTW that wants to 
give a removal credit must apply for authorization from the Approval 
Authority.
    (2) To whom application is made. An application for authorization to 
give removal credits (or modify existing ones) shall be submitted by the 
POTW to the Approval Authority.
    (3) When to apply. A POTW may apply for authorization to give or 
modify removal credits at any time.
    (4) Contents of the application. An application for authorization to 
give removal credits must be supported by the following information:
    (i) List of pollutants. A list of pollutants for which removal 
credits are proposed.
    (ii) Consistent Removal data. The data required pursuant to 
paragraph (b) of this section.
    (iii) Calculation of revised discharge limits. Proposed revised 
discharge limits for each affected subcategory of Industrial Users 
calculated in accordance with paragraph (a)(4) of this section.
    (iv) Local Pretreatment Program Certification. A certification that 
the POTW has an approved local pretreatment program or qualifies for the 
exception to this requirement found at paragraph (d) of this section.
    (v) Sludge management certification. A specific description of the 
POTW's current methods of using or disposing of its sludge and a 
certification that the granting of removal credits will not cause a 
violation of the sludge requirements identified in paragraph (a)(3)(iv) 
of this section.
    (vi) NPDES permit limit certification. A certification that the 
granting of removal credits will not cause a violation of the POTW's 
NPDES permit limits and conditions as required in paragraph (a)(3)(v) of 
this section.
    (5) Approval Authority review. The Approval Authority shall review 
the POTW's application for authorization to give or modify removal 
credits in accordance with the procedures of Sec.  403.11 and shall, in 
no event, have more that 180 days from public notice of an application 
to complete review.
    (6) EPA review of State removal credit approvals. Where the NPDES 
State has

[[Page 25]]

an approved pretreatment program, the Regional Administrator may agree 
in the Memorandum of Agreement under 40 CFR 123.24(d) to waive the right 
to review and object to submissions for authority to grant removal 
credits. Such an agreement shall not restrict the Regional 
Administrator's right to comment upon or object to permits issued to 
POTW's except to the extent 40 CFR 123.24(d) allows such restriction.
    (7) Nothing in these regulations precludes an Industrial User or 
other interested party from assisting the POTW in preparing and 
presenting the information necessary to apply for authorization.
    (f) Continuation and withdrawal of authorization--(1) Effect of 
authorization. (i) Once a POTW has received authorization to grant 
removal credits for a particular pollutant regulated in a categorical 
Pretreatment Standard it may automatically extend that removal credit to 
the same pollutant when it is regulated in other categorical standards, 
unless granting the removal credit will cause the POTW to violate the 
sludge requirements identified in paragraph (a)(3)(iv) of this section 
or its NPDES permit limits and conditions as required by paragraph 
(a)(3)(v) of this section. If a POTW elects at a later time to extend 
removal credits to a certain categorical Pretreatment Standard, 
industrial subcategory or one or more Industrial Users that initially 
were not granted removal credits, it must notify the Approval Authority.
    (2) Inclusion in POTW permit. Once authority is granted, the removal 
credits shall be included in the POTW's NPDES Permit as soon as possible 
and shall become an enforceable requirement of the POTW's NPDES permit. 
The removal credits will remain in effect for the term of the POTW's 
NPDES permit, provided the POTW maintains compliance with the conditions 
specified in paragraph (f)(4) of this section.
    (3) Compliance monitoring. Following authorization to give removal 
credits, a POTW shall continue to monitor and report on (at such 
intervals as may be specified by the Approval Authority, but in no case 
less than once per year) the POTW's removal capabilities. A minimum of 
one representative sample per month during the reporting period is 
required, and all sampling data must be included in the POTW's 
compliance report.
    (4) Modification or withdrawal of removal credits--(i) Notice of 
POTW. The Approval Authority shall notify the POTW if, on the basis of 
pollutant removal capability reports received pursuant to paragraph 
(f)(3) of this section or other relevant information available to it, 
the Approval Authority determines:
    (A) That one or more of the discharge limit revisions made by the 
POTW, of the POTW itself, no longer meets the requirements of this 
section, or
    (B) That such discharge limit revisions are causing a violation of 
any conditions or limits contained in the POTW's NPDES Permit.
    (ii) Corrective action. If appropriate corrective action is not 
taken within a reasonable time, not to exceed 60 days unless the POTW or 
the affected Industrial Users demonstrate that a longer time period is 
reasonably necessary to undertake the appropriate corrective action, the 
Approval Authority shall either withdraw such discharge limits or 
require modifications in the revised discharge limits.
    (iii) Public notice of withdrawal or modification. The Approval 
Authority shall not withdraw or modify revised discharge limits unless 
it shall first have notified the POTW and all Industrial Users to whom 
revised discharge limits have been applied, and made public, in writing, 
the reasons for such withdrawal or modification, and an opportunity is 
provided for a hearing. Following such notice and withdrawal or 
modification, all Industrial Users to whom revised discharge limits had 
been applied, shall be subject to the modified discharge limits or the 
discharge limits prescribed in the applicable categorical Pretreatment 
Standards, as appropriate, and shall achieve compliance with such limits 
within a reasonable time (not to exceed the period of time prescribed in 
the applicable categorical Pretreatment Standard(s) as may be specified 
by the Approval Authority.

[[Page 26]]

    (g) Removal credits in State-run pretreatment programs under Sec.  
403.10(e). Where an NPDES State with an approved pretreatment program 
elects to implement a local pretreatment program in lieu or requiring 
the POTW to develop such a program (as provided in Sec.  403.10(e)), the 
POTW will not be required to develop a pretreatment program as a 
precondition to obtaining authorization to give removal credits. The 
POTW will, however, be required to comply with the other conditions of 
paragraph (a)(3) of this section.
    (h) Compensation for overflow. ``Overflow'' means the intentional or 
unintentional diversion of flow from the POTW before the POTW Treatment 
Plant. POTWs which at least once annually Overflow untreated wastewater 
to receiving waters may claim Consistent Removal of a pollutant only by 
complying with either paragraphs (h)(1) or (h)(2) of this section. 
However, paragraph (h) of this section shall not apply where Industrial 
User(s) can demonstrate that Overflow does not occur between the 
Industrial User(s) and the POTW Treatment Plant;
    (1) The Industrial User provides containment or otherwise ceases or 
reduces Discharges from the regulated processes which contain the 
pollutant for which an allowance is requested during all circumstances 
in which an Overflow event can reasonably be expected to occur at the 
POTW or at a sewer to which the Industrial User is connected. Discharges 
must cease or be reduced, or pretreatment must be increased, to the 
extent necessary to compensate for the removal not being provided by the 
POTW. Allowances under this provision will only be granted where the 
POTW submits to the Approval Authority evidence that:
    (i) All Industrial Users to which the POTW proposes to apply this 
provision have demonstrated the ability to contain or otherwise cease or 
reduce, during circumstances in which an Overflow event can reasonably 
be expected to occur, Discharges from the regulated processes which 
contain pollutants for which an allowance is requested;
    (ii) The POTW has identified circumstances in which an Overflow 
event can reasonably be expected to occur, and has a notification or 
other viable plan to insure that Industrial Users will learn of an 
impending Overflow in sufficient time to contain, cease or reduce 
Discharging to prevent untreated Overflows from occurring. The POTW must 
also demonstrate that it will monitor and verify the data required in 
paragraph (h)(1)(iii) of this section, to insure that Industrial Users 
are containing, ceasing or reducing operations during POTW System 
Overflow; and
    (iii) All Industrial Users to which the POTW proposes to apply this 
provision have demonstrated the ability and commitment to collect and 
make available, upon request by the POTW, State Director or EPA Regional 
Administrator, daily flow reports or other data sufficient to 
demonstrate that all Discharges from regulated processes containing the 
pollutant for which the allowance is requested were contained, reduced 
or otherwise ceased, as appropriate, during all circumstances in which 
an Overflow event was reasonably expected to occur; or
    (2)(i) The Consistent Removal claimed is reduced pursuant to the 
following equation:
[GRAPHIC] [TIFF OMITTED] TR14OC05.000

Where:

rm = POTW's Consistent Removal rate for that pollutant as 
          established under paragraphs (a)(1) and (b)(2) of this section
rc = removal corrected by the Overflow factor
Z = hours per year that Overflows occurred between the Industrial 
          User(s) and the POTW Treatment Plant, the hours either to be 
          shown in the POTW's current NPDES permit application or the 
          hours, as demonstrated by verifiable techniques, that a 
          particular Industrial User's Discharge Overflows between the 
          Industrial User and the POTW Treatment Plant; and

    (ii) The POTW is complying with all NPDES permit requirements and 
any additional requirements in any order or decree, issued pursuant to 
the Clean Water Act affecting combined sewer overflows. These 
requirements include, but are not limited to, any combined

[[Page 27]]

sewer overflow requirements that conform to the Combined Sewer Overflow 
Control Policy.

Sec.  403.8  Pretreatment Program Requirements: Development and 
Implementation by POTW.

    (a) POTWs required to develop a pretreatment program. Any POTW (or 
combination of POTWs operated by the same authority) with a total design 
flow greater than 5 million gallons per day (mgd) and receiving from 
Industrial Users pollutants which Pass Through or Interfere with the 
operation of the POTW or are otherwise subject to Pretreatment Standards 
will be required to establish a POTW Pretreatment Program unless the 
NPDES State exercises its option to assume local responsibilities as 
provided for in Sec.  403.10(e). The Regional Administrator or Director 
may require that a POTW with a design flow of 5 mgd or less develop a 
POTW Pretreatment Program if he or she finds that the nature or volume 
of the industrial influent, treatment process upsets, violations of POTW 
effluent limitations, contamination of municipal sludge, or other 
circumstances warrant in order to prevent Interference with the POTW or 
Pass Through.
    (b) Deadline for Program Approval. A POTW which meets the criteria 
of paragraph (a) of this section must receive approval of a POTW 
Pretreatment Program no later than 3 years after the reissuance or 
modification of its existing NPDES permit but in no case later than July 
1, 1983. POTWs whose NPDES permits are modified under section 301(h) of 
the Act shall have a Pretreatment Program within three (3) years as 
provided for in 40 CFR part 125, subpart G. POTWs identified after July 
1, 1983 as being required to develop a POTW Pretreatment Program under 
paragraph (a) of this section shall develop and submit such a program 
for approval as soon as possible, but in no case later than one year 
after written notification from the Approval Authority of such 
identification. The POTW Pretreatment Program shall meet the criteria 
set forth in paragraph (f) of this section and shall be administered by 
the POTW to ensure compliance by Industrial Users with applicable 
Pretreatment Standards and Requirements.
    (c) Incorporation of approved programs in permits. A POTW may 
develop an appropriate POTW Pretreatment Program any time before the 
time limit set forth in paragraph (b) of this section. The POTW's NPDES 
Permit will be reissued or modified by the NPDES State or EPA to 
incorporate the approved Program as enforceable conditions of the 
Permit. The modification of a POTW's NPDES Permit for the purposes of 
incorporating a POTW Pretreatment Program approved in accordance with 
the procedure in Sec.  403.11 shall be deemed a minor Permit 
modification subject to the procedures in 40 CFR 122.63.
    (d) Incorporation of compliance schedules in permits. [Reserved]
    (e) Cause for reissuance or modification of Permits. Under the 
authority of section 402(b)(1)(C) of the Act, the Approval Authority may 
modify, or alternatively, revoke and reissue a POTW's Permit in order 
to:
    (1) Put the POTW on a compliance schedule for the development of a 
POTW Pretreatment Program where the addition of pollutants into a POTW 
by an Industrial User or combination of Industrial Users presents a 
substantial hazard to the functioning of the treatment works, quality of 
the receiving waters, human health, or the environment;
    (2) Coordinate the issuance of a section 201 construction grant with 
the incorporation into a permit of a compliance schedule for POTW 
Pretreatment Program;
    (3) Incorporate a modification of the permit approved under section 
301(h) or 301(i) of the Act;
    (4) Incorporate an approved POTW Pretreatment Program in the POTW 
permit; or
    (5) Incorporate a compliance schedule for the development of a POTW 
pretreatment program in the POTW permit.

[[Page 28]]

    (6) Incorporate the removal credits (established under Sec.  403.7) 
in the POTW permit.
    (f) POTW pretreatment requirements. A POTW pretreatment program must 
be based on the following legal authority and include the following 
procedures. These authorities and procedures shall at all times be fully 
and effectively exercised and implemented.
    (1) Legal authority. The POTW shall operate pursuant to legal 
authority enforceable in Federal, State or local courts, which 
authorizes or enables the POTW to apply and to enforce the requirements 
of sections 307 (b) and (c), and 402(b)(8) of the Act and any 
regulations implementing those sections. Such authority may be contained 
in a statute, ordinance, or series of contracts or joint powers 
agreements which the POTW is authorized to enact, enter into or 
implement, and which are authorized by State law. At a minimum, this 
legal authority shall enable the POTW to:
    (i) Deny or condition new or increased contributions of pollutants, 
or changes in the nature of pollutants, to the POTW by Industrial Users 
where such contributions do not meet applicable Pretreatment Standards 
and Requirements or where such contributions would cause the POTW to 
violate its NPDES permit;
    (ii) Require compliance with applicable Pretreatment Standards and 
Requirements by Industrial Users;
    (iii) Control through Permit, order, or similar means, the 
contribution to the POTW by each Industrial User to ensure compliance 
with applicable Pretreatment Standards and Requirements. In the case of 
Industrial Users identified as significant under Sec.  403.3(v), this 
control shall be achieved through individual permits or equivalent 
individual control mechanisms issued to each such User except as 
follows.
    (A)(1) At the discretion of the POTW, this control may include use 
of general control mechanisms if the following conditions are met. All 
of the facilities to be covered must:
    (i) Involve the same or substantially similar types of operations;
    (ii) Discharge the same types of wastes;
    (iii) Require the same effluent limitations;
    (iv) Require the same or similar monitoring; and
    (v) In the opinion of the POTW, are more appropriately controlled 
under a general control mechanism than under individual control 
mechanisms.
    (2) To be covered by the general control mechanism, the Significant 
Industrial User must file a written request for coverage that identifies 
its contact information, production processes, the types of wastes 
generated, the location for monitoring all wastes covered by the general 
control mechanism, any requests in accordance with Sec.  403.12(e)(2) 
for a monitoring waiver for a pollutant neither present nor expected to 
be present in the Discharge, and any other information the POTW deems 
appropriate. A monitoring waiver for a pollutant neither present nor 
expected to be present in the Discharge is not effective in the general 
control mechanism until after the POTW has provided written notice to 
the Significant Industrial User that such a waiver request has been 
granted in accordance with Sec.  403.12(e)(2). The POTW must retain a 
copy of the general control mechanism, documentation to support the 
POTW's determination that a specific Significant Industrial User meets 
the criteria in paragraphs (f)(1)(iii)(A)(1) through (5) of this 
section, and a copy of the User's written request for coverage for 3 
years after the expiration of the general control mechanism. A POTW may 
not control a Significant Industrial User through a general control 
mechanism where the facility is subject to production-based categorical 
Pretreatment Standards or categorical Pretreatment Standards expressed 
as mass of pollutant discharged per day or for Industrial Users whose 
limits are based on the Combined Wastestream Formula or Net/Gross 
calculations (Sec. Sec.  403.6(e) and 403.15).
    (B) Both individual and general control mechanisms must be 
enforceable and contain, at a minimum, the following conditions:
    (1) Statement of duration (in no case more than five years);
    (2) Statement of non-transferability without, at a minimum, prior 
notification to the POTW and provision of a

[[Page 29]]

copy of the existing control mechanism to the new owner or operator;
    (3) Effluent limits, including Best Management Practices, based on 
applicable general Pretreatment Standards in part 403 of this chapter, 
categorical Pretreatment Standards, local limits, and State and local 
law;
    (4) Self-monitoring, sampling, reporting, notification and 
recordkeeping requirements, including an identification of the 
pollutants to be monitored (including the process for seeking a waiver 
for a pollutant neither present nor expected to be present in the 
Discharge in accordance with Sec.  403.12(e)(2), or a specific waived 
pollutant in the case of an individual control mechanism), sampling 
location, sampling frequency, and sample type, based on the applicable 
general Pretreatment Standards in part 403 of this chapter, categorical 
Pretreatment Standards, local limits, and State and local law;
    (5) Statement of applicable civil and criminal penalties for 
violation of Pretreatment Standards and requirements, and any applicable 
compliance schedule. Such schedules may not extend the compliance date 
beyond applicable federal deadlines;
    (6) Requirements to control Slug Discharges, if determined by the 
POTW to be necessary.
    (iv) Require (A) the development of a compliance schedule by each 
Industrial User for the installation of technology required to meet 
applicable Pretreatment Standards and Requirements and (B) the 
submission of all notices and self-monitoring reports from Industrial 
Users as are necessary to assess and assure compliance by Industrial 
Users with Pretreatment Standards and Requirements, including but not 
limited to the reports required in Sec.  403.12.
    (v) Carry out all inspection, surveillance and monitoring procedures 
necessary to determine, independent of information supplied by 
Industrial Users, compliance or noncompliance with applicable 
Pretreatment Standards and Requirements by Industrial Users. 
Representatives of the POTW shall be authorized to enter any premises of 
any Industrial User in which a Discharge source or treatment system is 
located or in which records are required to be kept under Sec.  
403.12(o) to assure compliance with Pretreatment Standards. Such 
authority shall be at least as extensive as the authority provided under 
section 308 of the Act;
    (vi)(A) Obtain remedies for noncompliance by any Industrial User 
with any Pretreatment Standard and Requirement. All POTW's shall be able 
to seek injunctive relief for noncompliance by Industrial Users with 
Pretreatment Standards and Requirements. All POTWs shall also have 
authority to seek or assess civil or criminal penalties in at least the 
amount of $1,000 a day for each violation by Industrial Users of 
Pretreatment Standards and Requirements.
    (B) Pretreatment requirements which will be enforced through the 
remedies set forth in paragraph (f)(1)(vi)(A) of this section, will 
include but not be limited to, the duty to allow or carry out 
inspections, entry, or monitoring activities; any rules, regulations, or 
orders issued by the POTW; any requirements set forth in control 
mechanisms issued by the POTW; or any reporting requirements imposed by 
the POTW or these regulations in this part. The POTW shall have 
authority and procedures (after informal notice to the discharger) 
immediately and effectively to halt or prevent any discharge of 
pollutants to the POTW which reasonably appears to present an imminent 
endangerment to the health or welfare of persons. The POTW shall also 
have authority and procedures (which shall include notice to the 
affected industrial users and an opportunity to respond) to halt or 
prevent any discharge to the POTW which presents or may present an 
endangerment to the environment or which threatens to interfere with the 
operation of the POTW. The Approval Authority shall have authority to 
seek judicial relief and may also use administrative penalty authority 
when the POTW has sought a monetary penalty which the Approval Authority 
believes to be insufficient.
    (vii) Comply with the confidentiality requirements set forth in 
Sec.  403.14.
    (2) Procedures. The POTW shall develop and implement procedures to 
ensure compliance with the requirements

[[Page 30]]

of a Pretreatment Program. At a minimum, these procedures shall enable 
the POTW to:
    (i) Identify and locate all possible Industrial Users which might be 
subject to the POTW Pretreatment Program. Any compilation, index or 
inventory of Industrial Users made under this paragraph shall be made 
available to the Regional Administrator or Director upon request;
    (ii) Identify the character and volume of pollutants contributed to 
the POTW by the Industrial Users identified under paragraph (f)(2)(i) of 
this section. This information shall be made available to the Regional 
Administrator or Director upon request;
    (iii) Notify Industrial Users identified under paragraph (f)(2)(i) 
of this section, of applicable Pretreatment Standards and any applicable 
requirements under sections 204(b) and 405 of the Act and subtitles C 
and D of the Resource Conservation and Recovery Act. Within 30 days of 
approval pursuant to 40 CFR 403.8(f)(6), of a list of significant 
industrial users, notify each significant industrial user of its status 
as such and of all requirements applicable to it as a result of such 
status.
    (iv) Receive and analyze self-monitoring reports and other notices 
submitted by Industrial Users in accordance with the self-monitoring 
requirements in Sec.  403.12;
    (v) Randomly sample and analyze the effluent from Industrial Users 
and conduct surveillance activities in order to identify, independent of 
information supplied by Industrial Users, occasional and continuing 
noncompliance with Pretreatment Standards. Inspect and sample the 
effluent from each Significant Industrial User at least once a year, 
except as otherwise specified below:
    (A) Where the POTW has authorized the Industrial User subject to a 
categorical Pretreatment Standard to forego sampling of a pollutant 
regulated by a categorical Pretreatment Standard in accordance with 
Sec.  403.12(e)(3), the POTW must sample for the waived pollutant(s) at 
least once during the term of the Categorical Industrial User's control 
mechanism. In the event that the POTW subsequently determines that a 
waived pollutant is present or is expected to be present in the 
Industrial User's wastewater based on changes that occur in the User's 
operations, the POTW must immediately begin at least annual effluent 
monitoring of the User's Discharge and inspection.
    (B) Where the POTW has determined that an Industrial User meets the 
criteria for classification as a Non-Significant Categorical Industrial 
User, the POTW must evaluate, at least once per year, whether an 
Industrial User continues to meet the criteria in Sec.  403.3(v)(2).
    (C) In the case of Industrial Users subject to reduced reporting 
requirements under Sec.  403.12(e)(3), the POTW must randomly sample and 
analyze the effluent from Industrial Users and conduct inspections at 
least once every two years. If the Industrial User no longer meets the 
conditions for reduced reporting in Sec.  403.12(e)(3), the POTW must 
immediately begin sampling and inspecting the Industrial User at least 
once a year.
    (vi) Evaluate whether each such Significant Industrial User needs a 
plan or other action to control Slug Discharges. For Industrial Users 
identified as significant prior to November 14, 2005, this evaluation 
must have been conducted at least once by October 14, 2006; additional 
Significant Industrial Users must be evaluated within 1 year of being 
designated a Significant Industrial User. For purposes of this 
subsection, a Slug Discharge is any Discharge of a non-routine, episodic 
nature, including but not limited to an accidental spill or a non-
customary batch Discharge, which has a reasonable potential to cause 
Interference or Pass Through, or in any other way violate the POTW's 
regulations, local limits or Permit conditions. The results of such 
activities shall be available to the Approval Authority upon request. 
Significant Industrial Users are required to notify the POTW immediately 
of any changes at its facility affecting potential for a Slug Discharge. 
If the POTW decides that a slug control plan is needed, the plan shall 
contain, at a minimum, the following elements:
    (A) Description of discharge practices, including non-routine batch 
Discharges;

[[Page 31]]

    (B) Description of stored chemicals;
    (C) Procedures for immediately notifying the POTW of Slug 
Discharges, including any Discharge that would violate a prohibition 
under Sec.  403.5(b) with procedures for follow-up written notification 
within five days;
    (D) If necessary, procedures to prevent adverse impact from 
accidental spills, including inspection and maintenance of storage 
areas, handling and transfer of materials, loading and unloading 
operations, control of plant site run-off, worker training, building of 
containment structures or equipment, measures for containing toxic 
organic pollutants (including solvents), and/or measures and equipment 
for emergency response;
    (vii) Investigate instances of noncompliance with Pretreatment 
Standards and Requirements, as indicated in the reports and notices 
required under Sec.  403.12, or indicated by analysis, inspection, and 
surveillance activities described in paragraph (f)(2)(v) of this 
section. Sample taking and analysis and the collection of other 
information shall be performed with sufficient care to produce evidence 
admissible in enforcement proceedings or in judicial actions; and
    (viii) Comply with the public participation requirements of 40 CFR 
part 25 in the enforcement of National Pretreatment Standards. These 
procedures shall include provision for at least annual public 
notification in a newspaper(s) of general circulation that provides 
meaningful public notice within the jurisdiction(s) served by the POTW 
of Industrial Users which, at any time during the previous 12 months, 
were in significant noncompliance with applicable Pretreatment 
requirements. For the purposes of this provision, a Significant 
Industrial User (or any Industrial User which violates paragraphs 
(f)(2)(viii)(C), (D), or (H) of this section) is in significant 
noncompliance if its violation meets one or more of the following 
criteria:
    (A) Chronic violations of wastewater Discharge limits, defined here 
as those in which 66 percent or more of all of the measurements taken 
for the same pollutant parameter during a 6-month period exceed (by any 
magnitude) a numeric Pretreatment Standard or Requirement, including 
instantaneous limits, as defined by 40 CFR 403.3(l);
    (B) Technical Review Criteria (TRC) violations, defined here as 
those in which 33 percent or more of all of the measurements taken for 
the same pollutant parameter during a 6-month period equal or exceed the 
product of the numeric Pretreatment Standard or Requirement including 
instantaneous limits, as defined by 40 CFR 403.3(l) multiplied by the 
applicable TRC (TRC = 1.4 for BOD, TSS, fats, oil, and grease, and 1.2 
for all other pollutants except pH);
    (C) Any other violation of a Pretreatment Standard or Requirement as 
defined by 40 CFR 403.3(l) (daily maximum, long-term average, 
instantaneous limit, or narrative Standard) that the POTW determines has 
caused, alone or in combination with other Discharges, Interference or 
Pass Through (including endangering the health of POTW personnel or the 
general public);
    (D) Any discharge of a pollutant that has caused imminent 
endangerment to human health, welfare or to the environment or has 
resulted in the POTW's exercise of its emergency authority under 
paragraph (f)(1)(vi)(B) of this section to halt or prevent such a 
discharge;
    (E) Failure to meet, within 90 days after the schedule date, a 
compliance schedule milestone contained in a local control mechanism or 
enforcement order for starting construction, completing construction, or 
attaining final compliance;
    (F) Failure to provide, within 45 days after the due date, required 
reports such as baseline monitoring reports, 90-day compliance reports, 
periodic self-monitoring reports, and reports on compliance with 
compliance schedules;
    (G) Failure to accurately report noncompliance;
    (H) Any other violation or group of violations, which may include a 
violation of Best Management Practices, which the POTW determines will 
adversely affect the operation or implementation of the local 
Pretreatment program.
    (3) Funding. The POTW shall have sufficient resources and qualified 
personnel to carry out the authorities and

[[Page 32]]

procedures described in paragraphs (f) (1) and (2) of this section. In 
some limited circumstances, funding and personnel may be delayed where 
(i) the POTW has adequate legal authority and procedures to carry out 
the Pretreatment Program requirements described in this section, and 
(ii) a limited aspect of the Program does not need to be implemented 
immediately (see Sec.  403.9(b)).
    (4) Local limits. The POTW shall develop local limits as required in 
Sec.  403.5(c)(1), or demonstrate that they are not necessary.
    (5) The POTW shall develop and implement an enforcement response 
plan. This plan shall contain detailed procedures indicating how a POTW 
will investigate and respond to instances of industrial user 
noncompliance. The plan shall, at a minimum:
    (i) Describe how the POTW will investigate instances of 
noncompliance;
    (ii) Describe the types of escalating enforcement responses the POTW 
will take in response to all anticipated types of industrial user 
violations and the time periods within which responses will take place;
    (iii) Identify (by title) the official(s) responsible for each type 
of response;
    (iv) Adequately reflect the POTW's primary responsibility to enforce 
all applicable pretreatment requirements and standards, as detailed in 
40 CFR 403.8 (f)(1) and (f)(2).
    (6) The POTW shall prepare and maintain a list of its Industrial 
Users meeting the criteria in Sec.  403.3(v)(1). The list shall identify 
the criteria in Sec.  403.3(v)(1) applicable to each Industrial User 
and, where applicable, shall also indicate whether the POTW has made a 
determination pursuant to Sec.  403.3(v)(2) that such Industrial User 
should not be considered a Significant Industrial User. The initial list 
shall be submitted to the Approval Authority pursuant to Sec.  403.9 or 
as a non-substantial modification pursuant to Sec.  403.18(d). 
Modifications to the list shall be submitted to the Approval Authority 
pursuant to Sec.  403.12(i)(1).
    (g) A POTW that chooses to receive electronic documents must satisfy 
the requirements of 40 CFR part 3--(Electronic reporting).

Sec.  403.9  POTW pretreatment programs and/or authorization to revise
pretreatment standards: Submission for approval.

    (a) Who approves Program. A POTW requesting approval of a POTW 
Pretreatment Program shall develop a program description which includes 
the information set forth in paragraphs (b)(1) through (4) of this 
section. This description shall be submitted to the Approval Authority 
which will make a determination on the request for program approval in 
accordance with the procedures described in Sec.  403.11.
    (b) Contents of POTW program submission. The program description 
must contain the following information:
    (1) A statement from the City Solicitor or a city official acting in 
a comparable capacity (or the attorney for those POTWs which have 
independent legal counsel) that the POTW has authority adequate to carry 
out the programs described in Sec.  403.8. This statement shall:
    (i) Identify the provision of the legal authority under Sec.  
403.8(f)(1) which provides the basis for each procedure under Sec.  
403.8(f)(2);
    (ii) Identify the manner in which the POTW will implement the 
program requirements set forth in Sec.  403.8, including the means by 
which Pretreatment Standards will be applied to individual Industrial 
Users (e.g., by order, permit, ordinance, etc.); and,
    (iii) Identify how the POTW intends to ensure compliance with 
Pretreatment Standards and Requirements, and to enforce them in the 
event of noncompliance by Industrial Users;
    (2) A copy of any statutes, ordinances, regulations, agreements, or 
other authorities relied upon by the POTW for its administration of the 
Program. This Submission shall include a statement reflecting the 
endorsement or approval of the local

[[Page 33]]

boards or bodies responsible for supervising and/or funding the POTW 
Pretreatment Program if approved;
    (3) A brief description (including organization charts) of the POTW 
organization which will administer the Pretreatment Program. If more 
than one agency is responsible for administration of the Program the 
responsible agencies should be identified, their respective 
responsibilities delineated, and their procedures for coordination set 
forth; and
    (4) A description of the funding levels and full- and part-time 
manpower available to implement the Program;
    (c) Conditional POTW program approval. The POTW may request 
conditional approval of the Pretreatment Program pending the acquisition 
of funding and personnel for certain elements of the Program. The 
request for conditional approval must meet the requirements set forth in 
paragraph (b) of this section except that the requirements of paragraph 
(b) of this section, may be relaxed if the Submission demonstrates that:
    (1) A limited aspect of the Program does not need to be implemented 
immediately;
    (2) The POTW had adequate legal authority and procedures to carry 
out those aspects of the Program which will not be implemented 
immediately; and
    (3) Funding and personnel for the Program aspects to be implemented 
at a later date will be available when needed. The POTW will describe in 
the Submission the mechanism by which this funding will be acquired. 
Upon receipt of a request for conditional approval, the Approval 
Authority will establish a fixed date for the acquisition of the needed 
funding and personnel. If funding is not acquired by this date, the 
conditional approval of the POTW Pretreatment Program and any removal 
allowances granted to the POTW, may be modified or withdrawn.
    (d) Content of removal allowance submission. The request for 
authority to revise categorical Pretreatment Standards must contain the 
information required in Sec.  403.7(d).
    (e) Approval authority action. Any POTW requesting POTW Pretreatment 
Program approval shall submit to the Approval Authority three copies of 
the Submission described in paragraph (b), and if appropriate, (d) of 
this section. Within 60 days after receiving the Submission, the 
Approval Authority shall make a preliminary determination of whether the 
Submission meets the requirements of paragraph (b) and, if appropriate, 
(d) of this section. If the Approval Authority makes the preliminary 
determination that the Submission meets these requirements, the Approval 
Authority shall:
    (1) Notify the POTW that the Submission has been received and is 
under review; and
    (2) Commence the public notice and evaluation activities set forth 
in Sec.  403.11.
    (f) Notification where submission is defective. If, after review of 
the Submission as provided for in paragraph (e) of this section, the 
Approval Authority determines that the Submission does not comply with 
the requirements of paragraph (b) or (c) of this section, and, if 
appropriate, paragraph (d), of this section, the Approval Authority 
shall provide notice in writing to the applying POTW and each person who 
has requested individual notice. This notification shall identify any 
defects in the Submission and advise the POTW and each person who has 
requested individual notice of the means by which the POTW can comply 
with the applicable requirements of paragraphs (b), (c) of this section, 
and, if appropriate, paragraph (d) of this section.
    (g) Consistency with water quality management plans. (1) In order to 
be approved the POTW Pretreatment Program shall be consistent with any 
approved water quality management plan developed in accordance with 40 
CFR parts 130, 131, as revised, where such 208 plan includes Management 
Agency designations and addresses pretreatment in a manner consistent 
with 40 CFR part 403. In order to assure such consistency the Approval 
Authority shall solicit the review and comment of the appropriate 208 
Planning Agency during the public comment period provided for in Sec.  
403.11(b)(1)(ii) prior to approval or disapproval of the Program.
    (2) Where no 208 plan has been approved or where a plan has been 
approved but lacks Management Agency

[[Page 34]]

designations and/or does not address pretreatment in a manner consistent 
with this regulation, the Approval Authority shall nevertheless solicit 
the review and comment of the appropriate 208 planning agency.

FR 18017, Apr. 7, 1993]



Sec.  403.10  Development and submission of NPDES State pretreatment programs.

    (a) Approval of State Programs. No State NPDES program shall be 
approved under section 402 of the Act after the effective date of these 
regulations unless it is determined to meet the requirements of 
paragraph (f) of this section. Notwithstanding any other provision of 
this regulation, a State will be required to act upon those authorities 
which it currently possesses before the approval of a State Pretreatment 
Program.
    (b) [Reserved]
    (c) Failure to request approval. Failure of an NPDES State with a 
permit program approved under section 402 of the Act prior to December 
27, 1977, to seek approval of a State Pretreatment Program and failure 
of an approved State to administer its State Pretreatment Program in 
accordance with the requirements of this section constitutes grounds for 
withdrawal of NPDES program approval under section 402(c)(3) of the Act.
    (d) [Reserved]
    (e) State Program in lieu of POTW Program. Notwithstanding the 
provision of Sec.  403.8(a), a State with an approved Pretreatment 
Program may assume responsibility for implementing the POTW Pretreatment 
Program requirements set forth in Sec.  403.8(f) in lieu of requiring 
the POTW to develop a Pretreatment Program. However, this does not 
preclude POTW's from independently developing Pretreatment Programs.
    (f) State Pretreatment Program requirements. In order to be 
approved, a request for State Pretreatment Program Approval must 
demonstrate that the State Pretreatment Program has the following 
elements:
    (1) Legal authority. The Attorney General's Statement submitted in 
accordance with paragraph (g)(1)(i) of this section shall certify that 
the Director has authority under State law to operate and enforce the 
State Pretreatment Program to the extent required by this part and by 40 
CFR 123.27. At a minimum, the Director shall have the authority to:
    (i) Incorporate POTW Pretreatment Program conditions into permits 
issued to POTW's; require compliance by POTW's with these incorporated 
permit conditions; and require compliance by Industrial Users with 
Pretreatment Standards;
    (ii) Ensure continuing compliance by POTW's with pretreatment 
conditions incorporated into the POTW Permit through review of 
monitoring reports submitted to the Director by the POTW in accordance 
with Sec.  403.12 and ensure continuing compliance by Industrial Users 
with Pretreatment Standards through the review of self-monitoring 
reports submitted to the POTW or to the Director by the Industrial Users 
in accordance with Sec.  403.12;
    (iii) Carry out inspection, surveillance and monitoring procedures 
which will determine, independent of information supplied by the POTW, 
compliance or noncompliance by the POTW with pretreatment conditions 
incorporated into the POTW Permit; and carry out inspection, 
surveillance and monitoring procedures which will determine, independent 
of information supplied by the Industrial User, whether the Industrial 
User is in compliance with Pretreatment Standards;
    (iv) Seek civil and criminal penalties, and injunctive relief, for 
noncompliance by the POTW with pretreatment conditions incorporated into 
the POTW Permit and for noncompliance with Pretreatment Standards by 
Industrial Users as set forth in Sec.  403.8(f)(1)(vi). The Director 
shall have authority to seek judicial relief for noncompliance by 
Industrial Users even when the POTW has acted to seek such relief (e.g., 
if the POTW has sought a penalty which the Director finds to be 
insufficient);
    (v) Approve and deny requests for approval of POTW Pretreatment 
Programs submitted by a POTW to the Director;

[[Page 35]]

    (vi) Deny and recommend approval of (but not approve) requests for 
Fundamentally Different Factors variances submitted by Industrial Users 
in accordance with the criteria and procedures set forth in Sec.  
403.13; and
    (vii) Approve and deny requests for authority to modify categorical 
Pretreatment Standards to reflect removals achieved by the POTW in

Sec.  403.12  Reporting requirements for POTW's and industrial users.

    (a) [Reserved]
    (b) Reporting requirements for industrial users upon effective date 
of categorical pretreatment standard--baseline report. Within 180 days 
after the effective date of a categorical Pretreatment

[[Page 38]]

Standard, or 180 days after the final administrative decision made upon 
a category determination submission under Sec.  403.6(a)(4), whichever 
is later, existing Industrial Users subject to such categorical 
Pretreatment Standards and currently discharging to or scheduled to 
discharge to a POTW shall be required to submit to the Control Authority 
a report which contains the information listed in paragraphs (b)(1)-(7) 
of this section. At least 90 days prior to commencement of discharge, 
New Sources, and sources that become Industrial Users subsequent to the 
promulgation of an applicable categorical Standard, shall be required to 
submit to the Control Authority a report which contains the information 
listed in paragraphs (b)(1)-(5) of this section. New sources shall also 
be required to include in this report information on the method of 
pretreatment the source intends to use to meet applicable pretreatment 
standards. New Sources shall give estimates of the information requested 
in paragraphs (b) (4) and (5) of this section:
    (1) Identifying information. The User shall submit the name and 
address of the facility including the name of the operator and owners;
    (2) Permits. The User shall submit a list of any environmental 
control permits held by or for the facility;
    (3) Description of operations. The User shall submit a brief 
description of the nature, average rate of production, and Standard 
Industrial Classification of the operation(s) carried out by such 
Industrial User. This description should include a schematic process 
diagram which indicates points of Discharge to the POTW from the 
regulated processes.
    (4) Flow measurement. The User shall submit information showing the 
measured average daily and maximum daily flow, in gallons per day, to 
the POTW from each of the following:
    (i) Regulated process streams; and
    (ii) Other streams as necessary to allow use of the combined 
wastestream formula of Sec.  403.6(e). (See paragraph (b)(5)(iv) of this 
section.)

The Control Authority may allow for verifiable estimates of these flows 
where justified by cost or feasibility considerations.
    (5) Measurement of pollutants. (i) The user shall identify the 
Pretreatment Standards applicable to each regulated process;
    (ii) In addition, the User shall submit the results of sampling and 
analysis identifying the nature and concentration (or mass, where 
required by the Standard or Control Authority) of regulated pollutants 
in the Discharge from each regulated process. Both daily maximum and 
average concentration (or mass, where required) shall be reported. The 
sample shall be representative of daily operations. In cases where the 
Standard requires compliance with a Best Management Practice or 
pollution prevention alternative, the User shall submit documentation as 
required by the Control Authority or the applicable Standards to 
determine compliance with the Standard;
    (iii) The User shall take a minimum of one representative sample to 
compile that data necessary to comply with the requirements of this 
paragraph.
    (iv) Samples should be taken immediately downstream from 
pretreatment facilities if such exist or immediately downstream from the 
regulated process if no pretreatment exists. If other wastewaters are 
mixed with the regulated wastewater prior to pretreatment the User 
should measure the flows and concentrations necessary to allow use of 
the combined wastestream formula of Sec.  403.6(e) in order to evaluate 
compliance with the Pretreatment Standards. Where an alternate 
concentration or mass limit has been calculated in accordance with Sec.  
403.6(e) this adjusted limit along with supporting data shall be 
submitted to the Control Authority;
    (v) Sampling and analysis shall be performed in accordance with the 
techniques prescribed in 40 CFR part 136 and amendments thereto. Where 
40 CFR part 136 does not contain sampling or analytical techniques for 
the pollutant in question, or where the Administrator determines that 
the part 136 sampling and analytical techniques are inappropriate for 
the pollutant in question, sampling and analysis shall be performed by 
using validated analytical methods or any other applicable

[[Page 39]]

sampling and analytical procedures, including procedures suggested by 
the POTW or other parties, approved by the Administrator;
    (vi) The Control Authority may allow the submission of a baseline 
report which utilizes only historical data so long as the data provides 
information sufficient to determine the need for industrial pretreatment 
measures;
    (vii) The baseline report shall indicate the time, date and place, 
of sampling, and methods of analysis, and shall certify that such 
sampling and analysis is representative of normal work cycles and 
expected pollutant Discharges to the POTW;
    (6) Certification. A statement, reviewed by an authorized 
representative of the Industrial User (as defined in paragraph (l) of 
this section) and certified to by a qualified professional, indicating 
whether Pretreatment Standards are being met on a consistent basis, and, 
if not, whether additional operation and maintenance (O and M) and/or 
additional Pretreatment is required for the Industrial User to meet the 
Pretreatment Standards and Requirements; and
    (7) Compliance schedule. If additional pretreatment and/or O and M 
will be required to meet the Pretreatment Standards; the shortest 
schedule by which the Industrial User will provide such additional 
pretreatment and/or O and M. The completion date in this schedule shall 
not be later than the compliance date established for the applicable 
Pretreatment Standard.
    (i) Where the Industrial User's categorical Pretreatment Standard 
has been modified by a removal allowance (Sec.  403.7), the combined 
wastestream formula (Sec.  403.6(e)), and/or a Fundamentally Different 
Factors variance (Sec.  403.13) at the time the User submits the report 
required by paragraph (b) of this section, the information required by 
paragraphs (b)(6) and (7) of this section shall pertain to the modified 
limits.
    (ii) If the categorical Pretreatment Standard is modified by a 
removal allowance (Sec.  403.7), the combined wastestream formula (Sec.  
403.6(e)), and/or a Fundamentally Different Factors variance (Sec.  
403.13) after the User submits the report required by paragraph (b) of 
this section, any necessary amendments to the information requested by 
paragraphs (b)(6) and (7) of this section shall be submitted by the User 
to the Control Authority within 60 days after the modified limit is 
approved.
    (c) Compliance schedule for meeting categorical Pretreatment 
Standards. The following conditions shall apply to the schedule required 
by paragraph (b)(7) of this section:
    (1) The schedule shall contain increments of progress in the form of 
dates for the commencement and completion of major events leading to the 
construction and operation of additional pretreatment required for the 
Industrial User to meet the applicable categorical Pretreatment 
Standards (e.g., hiring an engineer, completing preliminary plans, 
completing final plans, executing contract for major components, 
commencing construction, completing construction, etc.).
    (2) No increment referred to in paragraph (c)(1) of this section 
shall exceed 9 months.
    (3) Not later than 14 days following each date in the schedule and 
the final date for compliance, the Industrial User shall submit a 
progress report to the Control Authority including, at a minimum, 
whether or not it complied with the increment of progress to be met on 
such date and, if not, the date on which it expects to comply with this 
increment of progress, the reason for delay, and the steps being taken 
by the Industrial User to return the construction to the schedule 
established. In no event shall more than 9 months elapse between such 
progress reports to the Control Authority.
    (d) Report on compliance with categorical pretreatment standard 
deadline. Within 90 days following the date for final compliance with 
applicable categorical Pretreatment Standards or in the case of a New 
Source following commencement of the introduction of wastewater into the 
POTW, any Industrial User subject to Pretreatment Standards and 
Requirements shall submit to the Control Authority a report containing 
the information described in paragraphs (b) (4)-(6) of this section.

[[Page 40]]

For Industrial Users subject to equivalent mass or concentration limits 
established by the Control Authority in accordance with the procedures 
in Sec.  403.6(c), this report shall contain a reasonable measure of the 
User's long term production rate. For all other Industrial Users subject 
to categorical Pretreatment Standards expressed in terms of allowable 
pollutant discharge per unit of production (or other measure of 
operation), this report shall include the User's actual production 
during the appropriate sampling period.
    (e) Periodic reports on continued compliance. (1) Any Industrial 
User subject to a categorical Pretreatment Standard (except a Non-
Significant Categorical User as defined in Sec.  403.3(v)(2)), after the 
compliance date of such Pretreatment Standard, or, in the case of a New 
Source, after commencement of the discharge into the POTW, shall submit 
to the Control Authority during the months of June and December, unless 
required more frequently in the Pretreatment Standard or by the Control 
Authority or the Approval Authority, a report indicating the nature and 
concentration of pollutants in the effluent which are limited by such 
categorical Pretreatment Standards. In addition, this report shall 
include a record of measured or estimated average and maximum daily 
flows for the reporting period for the Discharge reported in paragraph 
(b)(4) of this section except that the Control Authority may require 
more detailed reporting of flows. In cases where the Pretreatment 
Standard requires compliance with a Best Management Practice (or 
pollution prevention alternative), the User shall submit documentation 
required by the Control Authority or the Pretreatment Standard necessary 
to determine the compliance status of the User. At the discretion of the 
Control Authority and in consideration of such factors as local high or 
low flow rates, holidays, budget cycles, etc., the Control Authority may 
modify the months during which the above reports are to be submitted. 
For Industrial Users for which EPA or the authorized state, tribe, or 
territory is the Control Authority, as of December 21, 2025 or an EPA-
approved alternative date (see 40 CFR 127.24(e) or (f)), all reports 
submitted in compliance with this section must be submitted 
electronically by the industrial user to the Control 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), 40 CFR 122.22, and 40 CFR part 127. 40 CFR part 127 is not 
intended to undo existing requirements for electronic reporting. Prior 
to this date, and independent of 40 CFR part 127, the Industrial Users 
for which EPA or the authorized state, tribe, or territory is the 
Control Authority may be required to report electronically if specified 
by a particular control mechanism or if required to do so by state law.
    (2) The Control Authority may authorize the Industrial User subject 
to a categorical Pretreatment Standard to forego sampling of a pollutant 
regulated by a categorical Pretreatment Standard if the Industrial User 
has demonstrated through sampling and other technical factors that the 
pollutant is neither present nor expected to be 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 
Industrial User. This authorization is subject to the following 
conditions:
    (i) The Control Authority may authorize a waiver where a pollutant 
is determined to be present solely due to sanitary wastewater discharged 
from the facility provided that the sanitary wastewater is not regulated 
by an applicable categorical Standard and otherwise includes no process 
wastewater.
    (ii) The monitoring waiver is valid only for the duration of the 
effective period of the Permit or other equivalent individual control 
mechanism, but in no case longer than 5 years. The User must submit a 
new request for the waiver before the waiver can be granted for each 
subsequent control mechanism.
    (iii) In making a demonstration that a pollutant is not present, the 
Industrial User must provide data from at least one sampling of the 
facility's process wastewater prior to any treatment present at the 
facility that is representative of all wastewater from all processes.

[[Page 41]]

    The request for a monitoring waiver must be signed in accordance 
with paragraph (l) of this section and include the certification 
statement in Sec.  403.6(a)(2)(ii). Non-detectable sample results may 
only be used as a demonstration that a pollutant is not present if the 
EPA approved method from 40 CFR part 136 with the lowest minimum 
detection level for that pollutant was used in the analysis.
    (iv) Any grant of the monitoring waiver by the Control Authority 
must be included as a condition in the User's control mechanism. The 
reasons supporting the waiver and any information submitted by the User 
in its request for the waiver must be maintained by the Control 
Authority for 3 years after expiration of the waiver.
    (v) Upon approval of the monitoring waiver and revision of the 
User's control mechanism by the Control Authority, the Industrial User 
must certify on each report with the statement below, that there has 
been no increase in the pollutant in its wastestream due to activities 
of the Industrial User:

    Based on my inquiry of the person or persons directly responsible 
for managing compliance with the Pretreatment Standard for 40 CFR 
_______ [specify applicable National Pretreatment Standard part(s)], I 
certify that, to the best of my knowledge and belief, there has been no 
increase in the level of ______ [list pollutant(s)] in the wastewaters 
due to the activities at the facility since filing of the last periodic 
report under 40 CFR 403.12(e)(1).

    (vi) In the event that a waived pollutant is found to be present or 
is expected to be present based on changes that occur in the User's 
operations, the User must immediately: Comply with the monitoring 
requirements of paragraph (e)(1) of this section or other more frequent 
monitoring requirements imposed by the Control Authority; and notify the 
Control Authority.
    (vii) This provision does not supersede certification processes and 
requirements established in categorical Pretreatment Standards, except 
as otherwise specified in the categorical Pretreatment Standard.
    (3) The Control Authority may reduce the requirement in paragraph 
(e)(1) of this section to a requirement to report no less frequently 
than once a year, unless required more frequently in the Pretreatment 
Standard or by the Approval Authority, where the Industrial User meets 
all of the following conditions:
    (i) The Industrial User's total categorical wastewater flow does not 
exceed any of the following:
    (A) 0.01 percent of the design dry weather hydraulic capacity of the 
POTW, or 5,000 gallons per day, whichever is smaller, as measured by a 
continuous effluent flow monitoring device unless the Industrial User 
discharges in batches;
    (B) 0.01 percent of the design dry weather organic treatment 
capacity of the POTW; and
    (C) 0.01 percent of the maximum allowable headworks loading for any 
pollutant regulated by the applicable categorical Pretreatment Standard 
for which approved local limits were developed by a POTW in accordance 
with Sec.  403.5(c) and paragraph (d) of this section;
    (ii) The Industrial User has not been in significant noncompliance, 
as defined in Sec.  403.8(f)(2)(viii), for any time in the past two 
years;
    (iii) The Industrial User does not have daily flow rates, production 
levels, or pollutant levels that vary so significantly that decreasing 
the reporting requirement for this Industrial User would result in data 
that are not representative of conditions occurring during the reporting 
period pursuant to paragraph (g)(3) of this section;
    (iv) The Industrial User must notify the Control Authority 
immediately of any changes at its facility causing it to no longer meet 
conditions of paragraphs (e)(3)(i) or (ii) of this section. Upon 
notification, the Industrial User must immediately begin complying with 
the minimum reporting in paragraph (e)(1) of this section; and
    (v) The Control Authority must retain documentation to support the 
Control Authority's determination that a specific Industrial User 
qualifies for reduced reporting requirements under paragraph (e)(3) of 
this section for a period of 3 years after the expiration of the term of 
the control mechanism.

[[Page 42]]

    (4) For Industrial Users subject to equivalent mass or concentration 
limits established by the Control Authority in accordance with the 
procedures in Sec.  403.6(c), the report required by paragraph (e)(1) 
shall contain a reasonable measure of the User's long term production 
rate. For all other Industrial Users subject to categorical Pretreatment 
Standards expressed only in terms of allowable pollutant discharge per 
unit of production (or other measure of operation), the report required 
by paragraph (e)(1) shall include the User's actual average production 
rate for the reporting period.
    (f) Notice of potential problems, including slug loading. All 
categorical and non-categorical Industrial Users shall notify the POTW 
immediately of all discharges that could cause problems to the POTW, 
including any slug loadings, as defined by Sec.  403.5(b), by the 
Industrial User.
    (g) Monitoring and analysis to demonstrate continued compliance. (1) 
Except in the case of Non-Significant Categorical Users, the reports 
required in paragraphs (b), (d), (e), and (h) of this section shall 
contain the results of sampling and analysis of the Discharge, including 
the flow and the nature and concentration, or production and mass where 
requested by the Control Authority, of pollutants contained therein 
which are limited by the applicable Pretreatment Standards. This 
sampling and analysis may be performed by the Control Authority in lieu 
of the Industrial User. Where the POTW performs the required sampling 
and analysis in lieu of the Industrial User, the User will not be 
required to submit the compliance certification required under 
paragraphs (b)(6) and (d) of this section. In addition, where the POTW 
itself collects all the information required for the report, including 
flow data, the Industrial User will not be required to submit the 
report.
    (2) If sampling performed by an Industrial User indicates a 
violation, the User shall notify the Control Authority within 24 hours 
of becoming aware of the violation. The User shall also repeat the 
sampling and analysis and submit the results of the repeat analysis to 
the Control Authority within 30 days after becoming aware of the 
violation. Where the Control Authority has performed the sampling and 
analysis in lieu of the Industrial User, the Control Authority must 
perform the repeat sampling and analysis unless it notifies the User of 
the violation and requires the User to perform the repeat analysis. 
Resampling is not required if:
    (i) The Control Authority performs sampling at the Industrial User 
at a frequency of at least once per month; or
    (ii) The Control Authority performs sampling at the User between the 
time when the initial sampling was conducted and the time when the User 
or the Control Authority receives the results of this sampling.
    (3) The reports required in paragraphs (b), (d), (e) and (h) of this 
section must be based upon data obtained through appropriate sampling 
and analysis performed during the period covered by the report, which 
data are representative of conditions occurring during the reporting 
period. The Control Authority shall require that frequency of monitoring 
necessary to assess and assure compliance by Industrial Users with 
applicable Pretreatment Standards and Requirements. Grab samples must be 
used for pH, cyanide, total phenols, oil and grease, sulfide, and 
volatile organic compounds. For all other pollutants, 24-hour composite 
samples must be obtained through flow-proportional composite sampling 
techniques, unless time-proportional composite sampling or grab sampling 
is authorized by the Control Authority. Where time-proportional 
composite sampling or grab sampling is authorized by the Control 
Authority, the samples must be representative of the Discharge and the 
decision to allow the alternative sampling must be documented in the 
Industrial User file for that facility or facilities. Using protocols 
(including appropriate preservation) specified in 40 CFR part 136 and 
appropriate EPA guidance, multiple grab samples collected during a 24-
hour period may be composited prior to the analysis as follows: For 
cyanide, total phenols, and sulfides the samples may be composited in 
the laboratory or in the field; for volatile organics and oil & grease 
the samples may be composited in the laboratory.

[[Page 43]]

Composite samples for other parameters unaffected by the compositing 
procedures as documented in approved EPA methodologies may be authorized 
by the Control Authority, as appropriate.
    (4) For sampling required in support of baseline monitoring and 90-
day compliance reports required in paragraphs (b) and (d) of this 
section, a minimum of four (4) grab samples must be used for pH, 
cyanide, total phenols, oil and grease, sulfide and volatile organic 
compounds for facilities for which historical sampling data do not 
exist; for facilities for which historical sampling data are available, 
the Control Authority may authorize a lower minimum. For the reports 
required by paragraphs (e) and (h) of this section, the Control 
Authority shall require the number of grab samples necessary to assess 
and assure compliance by Industrial Users with Applicable Pretreatment 
Standards and Requirements.
    (5) All analyses shall be performed in accordance with procedures 
established by the Administrator pursuant to section 304(h) of the Act 
and contained in 40 CFR part 136 and amendments thereto or with any 
other test procedures approved by the Administrator. (See, Sec. Sec.  
136.4 and 136.5.) Sampling shall be performed in accordance with the 
techniques approved by the Administrator. Where 40 CFR part 136 does not 
include sampling or analytical techniques for the pollutants in 
question, or where the Administrator determines that the part 136 
sampling and analytical techniques are inappropriate for the pollutant 
in question, sampling and analyses shall be performed using validated 
analytical methods or any other sampling and analytical procedures, 
including procedures suggested by the POTW or other parties, approved by 
the Administrator.
    (6) If an Industrial User subject to the reporting requirement in 
paragraph (e) or (h) of this section monitors any regulated pollutant at 
the appropriate sampling location more frequently than required by the 
Control Authority, using the procedures prescribed in paragraph (g)(5) 
of this section, the results of this monitoring shall be included in the 
report.
    (h) Reporting requirements for Industrial Users not subject to 
categorical Pretreatment Standards. The Control Authority must require 
appropriate reporting from those Industrial Users with Discharges that 
are not subject to categorical Pretreatment Standards. Significant Non-
categorical Industrial Users must submit to the Control Authority at 
least once every six months (on dates specified by the Control 
Authority) a description of the nature, concentration, and flow of the 
pollutants required to be reported by the Control Authority. In cases 
where a local limit requires compliance with a Best Management Practice 
or pollution prevention alternative, the User must submit documentation 
required by the Control Authority to determine the compliance status of 
the User. These reports must be based on sampling and analysis performed 
in the period covered by the report, and in accordance with the 
techniques described in 40 CFR part 136 of this chapter and amendments 
thereto. This sampling and analysis may be performed by the Control 
Authority in lieu of the significant non-categorical Industrial User. 
For Industrial Users for which EPA or the authorized state, tribe, or 
territory is the Control Authority, as of December 21, 2025 or an EPA-
approved alternative date (see 40 CFR 127.24(e) or (f)), all reports 
submitted in compliance with this section must be submitted 
electronically by the industrial user to the Control 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), 40 CFR 122.22, and 40 CFR part 127. 40 CFR part 127 is not 
intended to undo existing requirements for electronic reporting. Prior 
to this date, and independent of 40 CFR part 127, the Industrial Users 
for which EPA or the authorized state, tribe, or territory is the 
Control Authority may be required to report electronically if specified 
by a particular control mechanism or if required to do so by state law.
    (i) Annual POTW reports. POTWs with approved Pretreatment Programs 
shall provide the Approval Authority with a report that briefly 
describes the POTW's program activities, including

[[Page 44]]

activities of all participating agencies, if more than one jurisdiction 
is involved in the local program. The report required by this section 
shall be submitted no later than one year after approval of the POTW's 
Pretreatment Program, and at least annually thereafter, and must 
include, at a minimum, the applicable required data in appendix A to 40 
CFR part 127. The report required by this section must also include a 
summary of changes to the POTW's pretreatment program that have not been 
previously reported to the Approval Authority and any other relevant 
information requested by the Approval Authority. As of December 21, 2025 
or an EPA-approved alternative date (see 40 CFR 127.24(e) or (f)), all 
annual reports submitted in compliance with this section must be 
submitted electronically by the POTW Pretreatment Program to the 
Approval 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 40 CFR part 3), 40 CFR 122.22, and 40 CFR part 127. 
40 CFR part 127 is not intended to undo existing requirements for 
electronic reporting. Prior to this date, and independent of 40 CFR part 
127, the Approval Authority may also require POTW Pretreatment Programs 
to electronically submit annual reports under this section if specified 
by a particular permit or if required to do so by state law.
    (j) Notification of changed Discharge. All Industrial Users shall 
promptly notify the Control Authority (and the POTW if the POTW is not 
the Control Authority) in advance of any substantial change in the 
volume or character of pollutants in their Discharge, including the 
listed or characteristic hazardous wastes for which the Industrial User 
has submitted initial notification under paragraph (p) of this section.
    (k) Compliance schedule for POTW's. The following conditions and 
reporting requirements shall apply to the compliance schedule for 
development of an approvable POTW Pretreatment Program required by Sec.  
403.8.
    (1) The schedule shall contain increments of progress in the form of 
dates for the commencement and completion of major events leading to the 
development and implementation of a POTW Pretreatment Program (e.g., 
acquiring required authorities, developing funding mechanisms, acquiring 
equipment);
    (2) No increment referred to in paragraph (k)(1) of this section 
shall exceed nine months;
    (3) Not later than 14 days following each date in the schedule and 
the final date for compliance, the POTW shall submit a progress report 
to the Approval Authority including, as a minimum, whether or not it 
complied with the increment of progress to be met on such date and, if 
not, the date on which it expects to comply with this increment of 
progress, the reason for delay, and the steps taken by the POTW to 
return to the schedule established. In no event shall more than nine 
months elapse between such progress reports to the Approval Authority.
    (l) Signatory requirements for Industrial User reports. The reports 
required by paragraphs (b), (d), and (e) of this section shall include 
the certification statement as set forth in Sec.  403.6(a)(2)(ii), and 
shall be signed as follows:
    (1) By a responsible corporate officer, if the Industrial User 
submitting the reports required by paragraphs (b), (d), and (e) of this 
section is a corporation. For the purpose of this paragraph, 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 performs similar policy- or decision-making functions for the 
corporation, 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 initiate and direct other 
comprehensive measures to assure long-term environmental compliance with 
environmental laws and regulations; can ensure that the necessary 
systems are established or actions taken to gather complete and accurate 
information for control mechanism requirements; and where authority to 
sign documents has been assigned or

[[Page 45]]

delegated to the manager in accordance with corporate procedures.
    (2) By a general partner or proprietor if the Industrial User 
submitting the reports required by paragraphs (b), (d), and (e) of this 
section is a partnership, or sole proprietorship respectively.
    (3) By a duly authorized representative of the individual designated 
in paragraph (l)(1) or (l)(2) of this section if:
    (i) The authorization is made in writing by the individual described 
in paragraph (l)(1) or (l)(2);
    (ii) The authorization specifies either an individual or a position 
having responsibility for the overall operation of the facility from 
which the Industrial Discharge originates, such as the position of plant 
manager, operator of a well, or well field superintendent, or a position 
of equivalent responsibility, or having overall responsibility for 
environmental matters for the company; and
    (iii) the written authorization is submitted to the Control 
Authority.
    (4) If an authorization under paragraph (l)(3) of this section is no 
longer accurate because a different individual or position has 
responsibility for the overall operation of the facility, or overall 
responsibility for environmental matters for the company, a new 
authorization satisfying the requirements of paragraph (l)(3) of this 
section must be submitted to the Control Authority prior to or together 
with any reports to be signed by an authorized representative.
    (m) Signatory requirements for POTW reports. Reports submitted to 
the Approval Authority by the POTW in accordance with paragraph (i) of 
this section must be signed by a principal executive officer, ranking 
elected official or other duly authorized employee. The duly authorized 
employee must be an individual or position having responsibility for the 
overall operation of the facility or the Pretreatment Program. This 
authorization must be made in writing by the principal executive officer 
or ranking elected official, and submitted to the Approval Authority 
prior to or together with the report being submitted.
    (n) Provisions Governing Fraud and False Statements: The reports and 
other documents required to be submitted or maintained under this 
section shall be subject to:
    (1) The provisions of 18 U.S.C. section 1001 relating to fraud and 
false statements;
    (2) The provisions of sections 309(c)(4) of the Act, as amended, 
governing false statements, representation or certification; and
    (3) The provisions of section 309(c)(6) regarding responsible 
corporate officers.
    (o) Record-keeping requirements. (1) Any Industrial User and POTW 
subject to the reporting requirements established in this section shall 
maintain records of all information resulting from any monitoring 
activities required by this section, including documentation associated 
with Best Management Practices. Such records shall include for all 
samples:
    (i) The date, exact place, method, and time of sampling and the 
names of the person or persons taking the samples;
    (ii) The dates analyses were performed;
    (iii) Who performed the analyses;
    (iv) The analytical techniques/methods use; and
    (v) The results of such analyses.
    (2) Any Industrial User or POTW subject to the reporting 
requirements established in this section (including documentation 
associated with Best Management Practices) shall be required to retain 
for a minimum of 3 years any records of monitoring activities and 
results (whether or not such monitoring activities are required by this 
section) and shall make such records available for inspection and 
copying by the Director and the Regional Administrator (and POTW in the 
case of an Industrial User). This period of retention shall be extended 
during the course of any unresolved litigation regarding the Industrial 
User or POTW or when requested by the Director or the Regional 
Administrator.
    (3) Any POTW to which reports are submitted by an Industrial User 
pursuant to paragraphs (b), (d), (e), and (h) of this section shall 
retain such reports for a minimum of 3 years and shall make such reports 
available for inspection and copying by the Director and

[[Page 46]]

the Regional Administrator. This period of retention shall be extended 
during the course of any unresolved litigation regarding the discharge 
of pollutants by the Industrial User or the operation of the POTW 
Pretreatment Program or when requested by the Director or the Regional 
Administrator.
    (p)(1) The Industrial User shall notify the POTW, the EPA Regional 
Waste Management Division Director, and State hazardous waste 
authorities in writing of any discharge into the POTW of a substance, 
which, if otherwise disposed of, would be a hazardous waste under 40 CFR 
part 261. Such notification must include the name of the hazardous waste 
as set forth in 40 CFR part 261, the EPA hazardous waste number, and the 
type of discharge (continuous, batch, or other). If the Industrial User 
discharges more than 100 kilograms of such waste per calendar month to 
the POTW, the notification shall also contain the following information 
to the extent such information is known and readily available to the 
Industrial User: An identification of the hazardous constituents 
contained in the wastes, an estimation of the mass and concentration of 
such constituents in the wastestream discharged during that calendar 
month, and an estimation of the mass of constituents in the wastestream 
expected to be discharged during the following twelve months. All 
notifications must take place within 180 days of the effective date of 
this rule. Industrial users who commence discharging after the effective 
date of this rule shall provide the notification no later than 180 days 
after the discharge of the listed or characteristic hazardous waste. Any 
notification under this paragraph need be submitted only once for each 
hazardous waste discharged. However, notifications of changed discharges 
must be submitted under 40 CFR 403.12 (j). The notification requirement 
in this section does not apply to pollutants already reported under the 
self-monitoring requirements of 40 CFR 403.12 (b), (d), and (e).
    (2) Dischargers are exempt from the requirements of paragraph (p)(1) 
of this section during a calendar month in which they discharge no more 
than fifteen kilograms of hazardous wastes, unless the wastes are acute 
hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). 
Discharge of more than fifteen kilograms of non-acute hazardous wastes 
in a calendar month, or of any quantity of acute hazardous wastes as 
specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time 
notification.
    Subsequent months during which the Industrial User discharges more 
than such quantities of any hazardous waste do not require additional 
notification.
    (3) In the case of any new regulations under section 3001 of RCRA 
identifying additional characteristics of hazardous waste or listing any 
additional substance as a hazardous waste, the Industrial User must 
notify the POTW, the EPA Regional Waste Management Waste Division 
Director, and State hazardous waste authorities of the discharge of such 
substance within 90 days of the effective date of such regulations.
    (4) In the case of any notification made under paragraph (p) of this 
section, the Industrial User shall certify that it has a program in 
place to reduce the volume and toxicity of hazardous wastes generated to 
the degree it has determined to be economically practical.
    (q) Annual certification by Non-Significant Categorical Industrial 
Users. A facility determined to be a Non-Significant Categorical 
Industrial User pursuant to Sec.  403.3(v)(2) must annually submit the 
following certification statement, signed in accordance with the 
signatory requirements in paragraph (l) of this section. This 
certification must accompany any alternative report required by the 
Control Authority:

    Based on my inquiry of the person or persons directly responsible 
for managing compliance with the categorical Pretreatment Standards 
under 40 CFR ____, I certify that, to the best of my knowledge and 
belief that during the period from ________ ____, to ________, ____ 
[month, days, year]:
    (a) The facility described as ________ [facility name] met the 
definition of a non-significant categorical Industrial User as described 
in Sec.  403.3(v)(2); (b) the facility complied with all applicable 
Pretreatment Standards and requirements during this reporting period; 
and (c) the facility never discharged more than 100 gallons of total 
categorical wastewater on any given day during this reporting

[[Page 47]]

period. This compliance certification is based upon the following 
information:

Sec.  403.13  Variances from categorical pretreatment standards for 
fundamentally different factors.

    (a) Definition. The term Requester means an Industrial User or a 
POTW or other interested person seeking a variance from the limits 
specified in a categorical Pretreatment Standard.
    (b) Purpose and scope. In establishing categorical Pretreatment 
Standards for existing sources, the EPA will take into account all the 
information it can collect, develop and solicit regarding the factors 
relevant to pretreatment standards under section 307(b). In some cases, 
information which may affect these Pretreatment Standards will not be 
available or, for other reasons, will not be considered during their 
development. As a result, it may be necessary on a case-by-case basis to 
adjust the limits in categorical Pretreatment Standards, making them 
either more or less stringent, as they apply to a certain Industrial 
User within an industrial category or subcategory. This will only be 
done if data specific to that Industrial User 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 an Industrial User are fundamentally different from 
the factors considered during development of a categorical Pretreatment 
Standard applicable to that User and further, that the existence of 
those factors justifies a different discharge limit than specified in 
the applicable categorical Pretreatment Standard, may request a 
fundamentally different factors variance under this section or such a 
variance request may be initiated by the EPA.
    (c) Criteria--(1) General criteria. A request for a variance based 
upon fundamentally different factors shall be approved only if:
    (i) There is an applicable categorical Pretreatment Standard which 
specifically controls the pollutant for which alternative limits have 
been requested; and
    (ii) Factors relating to the discharge controlled by the categorical 
Pretreatment Standard are fundamentally different from the factors 
considered by EPA in establishing the Standards; and
    (iii) The request for a variance is made in accordance with the 
procedural requirements in paragraphs (g) and (h) of this section.
    (2) Criteria applicable to less stringent limits. A variance request 
for the establishment of limits less stringent than required by the 
Standard shall be approved only if:
    (i) The alternative limit requested is no less stringent than 
justified by the fundamental difference;
    (ii) The alternative limit will not result in a violation of 
prohibitive discharge standards prescribed by or established under Sec.  
403.5;
    (iii) The alternative limit will not result in a non-water quality 
environmental impact (including energy requirements) fundamentally more 
adverse than the impact considered during development of the 
Pretreatment Standards; and
    (iv) Compliance with the Standards (either by using the technologies 
upon which the Standards are based or by using other control 
alternatives) would result in either:
    (A) A removal cost (adjusted for inflation) wholly out of proportion 
to the removal cost considered during development of the Standards; or
    (B) A non-water quality environmental impact (including energy 
requirements) fundamentally more adverse than the impact considered 
during development of the Standards.
    (3) Criteria applicable to more stringent limits. A variance request 
for the establishment of limits more stringent than required by the 
Standards shall be approved only if:

[[Page 48]]

    (i) The alternative limit request is no more stringent than 
justified by the fundamental difference; and
    (ii) Compliance with the alternative limit would not result in 
either:
    (A) A removal cost (adjusted for inflation) wholly out of proportion 
to the removal cost considered during development of the Standards; or
    (B) A non-water quality environmental impact (including energy 
requirements) fundamentally more adverse than the impact considered 
during development of the Standards.
    (d) Factors considered fundamentally different. Factors which may be 
considered fundamentally different are:
    (1) The nature or quality of pollutants contained in the raw waste 
load of the User's process wastewater:
    (2) The volume of the User's process wastewater and effluent 
discharged;
    (3) Non-water quality environmental impact of control and treatment 
of the User'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 User's equipment or facilities; processes employed; process 
changes; and engineering aspects of the application of control 
technology;
    (6) Cost of compliance with required control technology.
    (e) Factors which will not be considered fundamentally different. A 
variance request or portion of such a request under this section may not 
be granted on any of the following grounds:
    (1) The feasibility of installing the required waste treatment 
equipment within the time the Act allows;
    (2) The assertion that the Standards cannot be achieved with the 
appropriate waste treatment facilities installed, if such assertion is 
not based on factors listed in paragraph (d) of this section;
    (3) The User's ability to pay for the required waste treatment; or
    (4) The impact of a Discharge on the quality of the POTW's receiving 
waters.
    (f) State or local law. 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 required by Federal law.
    (g) Application deadline. (1) Requests for a variance and supporting 
information must be submitted in writing to the Director or to the 
Administrator (or his delegate), as appropriate.
    (2) In order to be considered, a request for a variance must be 
submitted no later than 180 days after the date on which a categorical 
Pretreatment Standard is published in the Federal Register.
    (3) Where the User has requested a categorical determination 
pursuant to Sec.  403.6(a), the User may elect to await the results of 
the category determination before submitting a variance request under 
this section. Where the User so elects, he or she must submit the 
variance request within 30 days after a final decision has been made on 
the categorical determination pursuant to Sec.  403.6(a)(4).
    (h) Contents submission. Written submissions for variance requests, 
whether made to the Administrator (or his delegate) or the Director, 
must include:
    (1) The name and address of the person making the request;
    (2) Identification of the interest of the Requester which is 
affected by the categorical Pretreatment Standard for which the variance 
is requested;
    (3) Identification of the POTW currently receiving the waste from 
the Industrial User for which alternative discharge limits are 
requested;
    (4) Identification of the categorical Pretreatment Standards which 
are applicable to the Industrial User;
    (5) A list of each pollutant or pollutant parameter for which an 
alternative discharge limit is sought;
    (6) The alternative discharge limits proposed by the Requester for 
each pollutant or pollutant parameter identified in paragraph (h)(5) of 
this section;
    (7) A description of the Industrial User's existing water pollution 
control facilities;
    (8) A schematic flow representation of the Industrial User's water 
system including water supply, process wastewater systems, and points of 
Discharge; and
    (9) A Statement of facts clearly establishing why the variance 
request should be approved, including detailed

[[Page 49]]

support data, documentation, and evidence necessary to fully evaluate 
the merits of the request, e.g., technical and economic data collected 
by the EPA and used in developing each pollutant discharge limit in the 
Pretreatment Standard.
    (i) Deficient requests. The Administrator (or his delegate) or the 
Director will only act on written requests for variances that contain 
all of the information required. Persons who have made incomplete 
submissions will be notified by the Administrator (or his delegate) or 
the Director that their requests are deficient and unless the time 
period is extended, will be given up to thirty days to remedy the 
deficiency. If the deficiency is not corrected within the time period 
allowed by the Administrator (or his delegate) or the Director, the 
request for a variance shall be denied.
    (j) Public notice. Upon receipt of a complete request, the 
Administrator (or his delegate) or the Director will provide notice of 
receipt, opportunity to review the submission, and opportunity to 
comment.
    (1) The public notice shall be circulated in a manner designed to 
inform interested and potentially interested persons of the request. 
Procedures for the circulation of public notice shall include mailing 
notices to:
    (i) The POTW into which the Industrial User requesting the variance 
discharges;
    (ii) Adjoining States whose waters may be affected; and
    (iii) Designated 208 planning agencies, Federal and State fish, 
shellfish and wildlife resource agencies; and to any other person or 
group who has requested individual notice, including those on 
appropriate mailing lists.
    (2) The public notice shall provide for a period not less than 30 
days following the date of the public notice during which time 
interested persons may review the request and submit their written views 
on the request.
    (3) Following the comment period, the Administrator (or his 
delegate) or the Director will make a determination on the request 
taking into consideration any comments received. Notice of this final 
decision shall be provided to the requester (and the Industrial User for 
which the variance is requested if different), the POTW into which the 
Industrial User discharges and all persons who submitted comments on the 
request.
    (k) Review of requests by state. (1) Where the Director finds that 
fundamentally different factors do not exist, he may deny the request 
and notify the requester (and Industrial User where they are not the 
same) and the POTW of the denial.
    (2) Where the Director finds that fundamentally different factors do 
exist, he shall forward the request, with a recommendation that the 
request be approved, to the Administrator (or his delegate).
    (l) Review of requests by EPA. (1) Where the Administrator (or his 
delegate) finds that fundamentally different factors do not exist, he 
shall deny the request for a variance and send a copy of his 
determination to the Director, to the POTW, and to the requester (and to 
the Industrial User, where they are not the same).
    (2) Where the Administrator (or his delegate) finds that 
fundamentally different factors do exist, and that a partial or full 
variance is justified, he will approve the variance. In approving the 
variance, the Administrator (or his delegate) will:
    (i) Prepare recommended alternative discharge limits for the 
Industrial User either more or less stringent than those prescribed by 
the applicable categorical Pretreatment Standard to the extent warranted 
by the demonstrated fundamentally different factors;
    (ii) Provide the following information in his written determination:
    (A) The recommended alternative discharge limits for the Industrial 
User concerned;
    (B) The rationale for the adjustment of the Pretreatment Standard 
(including the reasons for recommending that the variance be granted) 
and an explanation of how the recommended alternative discharge limits 
were derived;
    (C) The supporting evidence submitted to the Administrator (or his 
delegate); and
    (D) Other information considered by the Administrator (or his 
delegate) in developing the recommended alternative discharge limits;

[[Page 50]]

    (iii) Notify the Director and the POTW of his or her determination; 
and
    (iv) Send the information described in paragraphs (l)(2) (i) and 
(ii) of this section to the Requestor (and to the Industrial User where 
they are not the same).
    (m) Request for hearing. (1) Within 30 days following the date of 
receipt of the notice of the decision of the Administrator's delegate on 
a variance request, the requester or any other interested person may 
submit a petition to the Regional Administrator for a hearing to 
reconsider or contest the decision. If such a request is submitted by a 
person other than the Industrial User the person shall simultaneously 
serve a copy of the request on the Industrial User.
    (2) If the Regional Administrator declines to hold a hearing and the 
Regional Administrator affirms the findings of the Administrator's 
delegate the requester may submit a petition for a hearing to the 
Environmental Appeals Board (which is described in Sec.  1.25 of this 
title) within 30 days of the Regional Administrator's decision.

Sec.  403.14  Confidentiality.

    (a) EPA authorities. 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) Effluent data. Information and data provided to the Control 
Authority pursuant to this part which is effluent data shall be 
available to the public without restriction.
    (c) State or POTW. All other information which is submitted to the 
State or POTW shall be available to the public at least to the extent 
provided by 40 CFR 2.302.



Sec.  403.15  Net/Gross calculation.

    (a) Application. Categorical Pretreatment Standards may be adjusted 
to reflect the presence of pollutants in the Industrial User's intake 
water in accordance with this section. Any Industrial User wishing to 
obtain credit for intake pollutants must make application to the Control 
Authority. Upon request of the Industrial User, the applicable Standard 
will be calculated on a ``net'' basis (i.e., adjusted to reflect credit 
for pollutants in the intake water) if the requirements of paragraph (b) 
of this section are met.
    (b) Criteria. (1) Either:
    (i) The applicable categorical Pretreatment Standards contained in 
40 CFR subchapter N specifically provide that they shall be applied on a 
net basis; or
    (ii) The Industrial User demonstrates that the control system it 
proposes or uses to meet applicable categorical Pretreatment Standards 
would, if properly installed and operated, meet the Standards in the 
absence of pollutants in the intake waters.
    (2) Credit for generic pollutants such as biochemical oxygen demand 
(BOD), total suspended solids (TSS), and oil and grease should not be 
granted unless the Industrial User demonstrates that the constituents of 
the generic measure in the User's 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 categorical Pretreatment Standard(s), up to a maximum value 
equal to the influent value. Additional monitoring may be necessary to 
determine eligibility for credits and compliance with Standard(s) 
adjusted under this section.

[[Page 51]]

    (4) Credit shall be granted only if the User demonstrates that the 
intake water is drawn from the same body of water as that into which the 
POTW discharges. The Control Authority may waive this requirement if it 
finds that no environmental degradation will result.

[70 FR 60198, Oct. 14, 2005]



Sec.  403.16  Upset provision.

    (a) Definition. For the purposes of this section, Upset means an 
exceptional incident in which there is unintentional and temporary 
noncompliance with categorical Pretreatment Standards because of factors 
beyond the reasonable control of the Industrial User. 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.
    (b) Effect of an upset. An Upset shall constitute an affirmative 
defense to an action brought for noncompliance with categorical 
Pretreatment Standards if the requirements of paragraph (c) are met.
    (c) Conditions necessary for a demonstration of upset. An Industrial 
User who wishes to establish the affirmative defense of Upset shall 
demonstrate, through properly signed, contemporaneous operating logs, or 
other relevant evidence that:
    (1) An Upset occurred and the Industrial User can identify the 
cause(s) of the Upset;
    (2) The facility was at the time being operated in a prudent and 
workman-like manner and in compliance with applicable operation and 
maintenance procedures;
    (3) The Industrial User has submitted the following information to 
the POTW and Control Authority within 24 hours of becoming aware of the 
Upset (if this information is provided orally, a written submission must 
be provided within five days):
    (i) A description of the Indirect Discharge and cause of 
noncompliance;
    (ii) The period of noncompliance, including exact dates and times 
or, if not corrected, the anticipated time the noncompliance is expected 
to continue;
    (iii) Steps being taken and/or planned to reduce, eliminate and 
prevent recurrence of the noncompliance.
    (d) Burden of proof. In any enforcement proceeding the Industrial 
User seeking to establish the occurrence of an Upset shall have the 
burden of proof.
    (e) Reviewability of agency consideration of claims of upset. In the 
usual exercise of prosecutorial discretion, Agency enforcement personnel 
should review any claims that non-compliance was caused by an Upset. No 
determinations made in the course of the review constitute final Agency 
action subject to judicial review. Industrial Users will have the 
opportunity for a judicial determination on any claim of Upset only in 
an enforcement action brought for noncompliance with categorical 
Pretreatment Standards.
    (f) User responsibility in case of upset. The Industrial User shall 
control production or all Discharges to the extent necessary to maintain 
compliance with categorical Pretreatment Standards upon reduction, loss, 
or failure of its treatment facility until the facility is restored or 
an alternative method of treatment is provided. This requirement applies 
in the situation where, among other things, the primary source of power 
of the treatment facility is reduced, lost or fails.

Sec.  403.17  Bypass.

    (a) Definitions. (1) Bypass means the intentional diversion of 
wastestreams from any portion of an Industrial User's treatment 
facility.
    (2) 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.
    (b) Bypass not violating applicable Pretreatment Standards or 
Requirements. An Industrial User may allow any bypass to occur which 
does not cause Pretreatment Standards or Requirements to be violated, 
but only if it also

[[Page 52]]

is for essential maintenance to assure efficient operation. These 
bypasses are not subject to the provision of paragraphs (c) and (d) of 
this section.
    (c) Notice. (1) If an Industrial User knows in advance of the need 
for a bypass, it shall submit prior notice to the Control Authority, if 
possible at least ten days before the date of the bypass.
    (2) An Industrial User shall submit oral notice of an unanticipated 
bypass that exceeds applicable Pretreatment Standards to the Control 
Authority within 24 hours from the time the Industrial User becomes 
aware of the bypass. A written submission shall also be provided within 
5 days of the time the Industrial User becomes aware of the bypass. The 
written submission shall contain a description of the bypass and its 
cause; the duration of the bypass, including exact dates and times, and, 
if the bypass 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 bypass. The Control Authority may waive 
the written report on a case-by-case basis if the oral report has been 
received within 24 hours.
    (d) Prohibition of bypass. (1) Bypass is prohibited, and the Control 
Authority may take enforcement action against an Industrial User for a 
bypass, unless;
    (i) Bypass was unavoidable to prevent loss of life, personal injury, 
or severe property damage;
    (ii) 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 
preventative maintenance; and
    (iii) The Industrial User submitted notices as required under 
paragraph (c) of this section.
    (2) The Control Authority may approve an anticipated bypass, after 
considering its adverse effects, if the Control Authority determines 
that it will meet the three conditions listed in paragraph (d)(1) of 
this section.

Sec.  403.18  Modification of POTW pretreatment programs.

    (a) General. Either the Approval Authority or a POTW with an 
approved POTW Pretreatment Program may initiate program modification at 
any time to reflect changing conditions at the POTW. Program 
modification is necessary whenever there is a significant change in the 
operation of a POTW Pretreatment Program that differs from the 
information in the POTW's submission, as approved under Sec.  403.11.
    (b) Substantial modifications defined. Substantial modifications 
include:
    (1) Modifications that relax POTW legal authorities (as described in 
Sec.  403.8(f)(1)), except for modifications that directly reflect a 
revision to this part 403 or to 40 CFR chapter I, subchapter N, and are 
reported pursuant to paragraph (d) of this section;
    (2) Modifications that relax local limits, except for the 
modifications to local limits for pH and reallocations of the Maximum 
Allowable Industrial Loading of a pollutant that do not increase the 
total industrial loadings for the pollutant, which are reported pursuant 
to paragraph (d) of this section. Maximum Allowable Industrial Loading 
means the total mass of a pollutant that all Industrial Users of a POTW 
(or a subgroup of Industrial Users identified by the POTW) may discharge 
pursuant to limits developed under Sec.  403.5(c);
    (3) Changes to the POTW's control mechanism, as described in Sec.  
403.8(f)(1)(iii);
    (4) A decrease in the frequency of self-monitoring or reporting 
required of industrial users;
    (5) A decrease in the frequency of industrial user inspections or 
sampling by the POTW;
    (6) Changes to the POTW's confidentiality procedures; and
    (7) Other modifications designated as substantial modifications by 
the Approval Authority on the basis that the modification could have a 
significant impact on the operation of the POTW's

[[Page 53]]

Pretreatment Program; could result in an increase in pollutant loadings 
at the POTW; or could result in less stringent requirements being 
imposed on Industrial Users of the POTW.
    (c) Approval procedures for substantial modifications. (1) The POTW 
shall submit to the Approval Authority a statement of the basis for the 
desired program modification, a modified program description (see Sec.  
403.9(b)), or such other documents the Approval Authority determines to 
be necessary under the circumstances.
    (2) The Approval Authority shall approve or disapprove the 
modification based on the requirements of Sec.  403.8(f) and using the 
procedures in Sec.  403.11(b) through (f), except as provided in 
paragraphs (c) (3) and (4) of this section. The modification shall 
become effective upon approval by the Approval Authority.
    (3) The Approval Authority need not publish a notice of decision 
under Sec.  403.11(e) provided: The notice of request for approval under 
Sec.  403.11(b)(1) states that the request will be approved if no 
comments are received by a date specified in the notice; no substantive 
comments are received; and the request is approved without change.
    (4) Notices required by Sec.  403.11 may be performed by the POTW 
provided that the Approval Authority finds that the POTW notice 
otherwise satisfies the requirements of Sec.  403.11.
    (d) Approval procedures for non-substantial modifications. (1) The 
POTW shall notify the Approval Authority of any non-substantial 
modification at least 45 days prior to implementation by the POTW, in a 
statement similar to that provided for in paragraph (c)(1) of this 
section.
    (2) Within 45 days after the submission of the POTW's statement, the 
Approval Authority shall notify the POTW of its decision to approve or 
disapprove the non-substantial modification.
    (3) If the Approval Authority does not notify the POTW within 45 
days of its decision to approve or deny the modification, or to treat 
the modification as substantial under paragraph (b)(7) of this section, 
the POTW may implement the modification.
    (e) Incorporation in permit. All modifications shall be incorporated 
into the POTW's NPDES permit upon approval. The permit will be modified 
to incorporate the approved modification in accordance with 40 CFR 
122.63(g).

[62 FR 38414, July 17, 1997]



Sec.  403.19  Provisions of specific applicability to the Owatonna Waste
Water Treatment Facility.

    (a) For the purposes of this section, the term ``Participating 
Industrial Users'' includes the following Industrial Users in the City 
of Owatonna, Minnesota: Crown Cork and Seal Company, Inc.; Cybex 
International Inc.; Josten's Inc.--Southtown Facility; SPx Corporation, 
Service Solutions Division; Truth Hardware Corporation; and Uber Tanning 
Company.
    (b) For a Participating Industrial User discharging to the Owatonna 
Waste Water Treatment Facility in Owatonna, Minnesota, when a 
categorical Pretreatment Standard is expressed in terms of pollutant 
concentration the City of Owatonna may convert the limit to a mass limit 
by multiplying the five-year, long-term average process flows of the 
Participating Industrial User (or a shorter period if production has 
significantly increased or decreased during the five year period) by the 
concentration-based categorical Pretreatment Standard. Participating 
Industrial Users must notify the City in the event production rates are 
expected to vary by more than 20 percent from a baseline production rate 
determined by Owatonna when it establishes a Participating Industrial 
User's initial mass limit. To remain eligible to receive equivalent mass 
limits the Participating Industrial User must maintain at least the same 
level of treatment as at the time the equivalent mass limit is 
established. Upon notification of a revised production rate from a 
Participating Industrial User, the City will reassess the 
appropriateness of the mass limit. Owatonna shall reestablish the 
concentration-based limit if a Participating Industrial User does not 
maintain at least the same level of treatment as when the equivalent 
mass limit was established.

[[Page 54]]

    (c) If a categorical Participating Industrial User of the Owatonna 
Waste Water Treatment Facility has demonstrated through sampling and 
other technical factors, including a comparison of three years of 
effluent data with background data, that pollutants regulated through 
categorical Pretreatment Standards, other than 40 CFR part 414, are not 
expected to be present in quantities greater than the background 
influent concentration to the industrial process, the City of Owatonna 
may reduce the sampling frequency specified in Sec.  403.8(f)(2)(v) to 
once during the term of the categorical Participating Industrial User's 
permit.
    (d) If a Participating Industrial User is discharging to the 
Owatonna Waste Water Treatment Facility in Owatonna, Minnesota and is 
subject to a categorical Pretreatment Standard other than one codified 
at 40 CFR part 414, the City of Owatonna may authorize the Participating 
Industrial User to forego sampling of a pollutant if the Participating 
Industrial User has demonstrated through sampling and other technical 
factors, including a comparison of three years of effluent data with 
background data, that the pollutant is not expected to be present in 
quantities greater than the background influent concentration to the 
industrial process, and the Participating Industrial User certifies on 
each report, with the following statement, that there has been no 
increase in the pollutant in its wastestream due to activities of the 
Participating Industrial User. The following statement is to be included 
as a comment to the periodic reports required by Sec.  403.12(e):

    ``Based on my inquiry of the person or persons directly responsible 
for managing compliance with the pretreatment standard for 40 CFR __, I 
certify that, to the best of my knowledge and belief, the raw materials, 
industrial processes, and potential by-products have not contributed 
this pollutant to the wastewaters since filing of the last periodic 
report under 40 CFR 403.12(e).''

    (e) If the average daily loading from the Participating Industrial 
Users to the Owatonna Waste Water Treatment Facility is equal to or less 
than 0.68 pounds per day of chromium, 0.25 pounds per day of copper, 
1.17 pounds per day of nickel, and 1.01 pounds per day of zinc, Owatonna 
may authorize a categorical Participating Industrial User to satisfy the 
reporting requirements of Sec.  403.12(e) with an annual report provided 
on a date specified by Owatonna, provided that the Participating 
Industrial User has no reasonable potential to violate a Pretreatment 
Standard for any pollutant for which reduced monitoring is being 
allowed, and has not been in Significant Noncompliance within the 
previous three years.
    (f) The Owatonna Waste Water Treatment Facility in Owatonna, 
Minnesota shall post public notice of all Significant Noncompliance 
subject to the publication requirement in Sec.  403.8(f)(2)(vii) at the 
Minnesota Pollution Control Agency website for a period of one year, as 
soon as practicable upon identifying the violations. In addition, the 
Owatonna Waste Water Treatment Facility shall post an explanation of how 
Significant Noncompliance is determined, and a contact name and phone 
number for information regarding other, non-Significant Noncompliance 
violations. If a violation is not corrected within thirty (30) calendar 
days or results in pass through or interference at the Owatonna Waste 
Water Treatment Facility, publication must also be made in the format 
specified in Sec.  403.8(f)(2)(vii).
    (g) The provisions of this section shall expire on October 6, 2005.

[65 FR 59747, Oct. 6, 2000]



Sec.  403.20  Pretreatment Program Reinvention Pilot Projects Under Project XL.

    The Approval Authority may allow any publicly owned treatment works 
(POTW) that has a final ``Project XL'' agreement to implement a 
Pretreatment Program that includes legal authorities and requirements 
that are different than the administrative requirements otherwise 
applicable under this part. The POTW must submit any such alternative 
requirements as a substantial program modification in accordance with 
the procedures outlined in Sec.  403.18. The approved modified program 
must be incorporated as an enforceable part of the POTW's NPDES permit. 
The Approval Authority must include a reopener clause in the

[[Page 55]]

POTW's NPDES permit that directs the POTW to discontinue implementing 
the approved alternative requirements and resume implementation of its 
previously approved pretreatment program if the Approval Authority 
determines that the primary objectives of the Local Pilot Pretreatment 
Program are not being met or the ``Project XL'' agreement expires or is 
otherwise terminated.

               Sec. Appendixes A-C to Part 403 [Reserved]



     Sec. Appendix D to Part 403--Selected Industrial Subcategories 
   Considered Dilute for Purposes of the Combined Wastestream Formula

    The following industrial subcategories are considered to have dilute 
wastestreams for purposes of the combined wastestream formula. They 
either were or could have been excluded from categorical pretreatment 
standards pursuant to paragraph 8 of the Natural Resources Defense 
Council, Inc., et al. v. Costle Consent Decree for one or more of the 
following four reasons: (1) The pollutants of concern are not detectable 
in the effluent from the industrial user (paragraph 8(a)(iii)); (2) the 
pollutants of concern are present only in trace amounts and are neither 
causing nor likely to cause toxic effects (paragraph 8(a)(iii)); (3) the 
pollutants of concern are present in amounts too small to be effectively 
reduced by technologies known to the Administrator (paragraph 
8(a)(iii)); or (4) the wastestream contains only pollutants which are 
compatible with the POTW (paragraph 8(b)(i)). In some instances, 
different rationales were given for exclusion under paragraph 8. 
However, EPA has reviewed these subcategories and has determined that 
exclusion could have occurred due to one of the four reasons listed 
above.
    This list is complete as of October 9, 1986. It will be updated 
periodically for the convenience of the reader.

            Sec. Appendix E to Part 403--Sampling Procedures

                           I. Composite Method

    A. It is recommended that influent and effluent operational data be 
obtained through 24-hour flow proportional composite samples. Sampling 
may be done manually or automatically, and discretely or continuously. 
If discrete sampling is employed, at least 12 aliquots should be 
composited. Discrete sampling may be flow proportioned either by varying 
the time interval between each aliquot or the volume of each aliquot. 
All composites should be flow proportional to either the stream flow at 
the time of collection of the influent aliquot or to the total influent 
flow since the previous influent aliquot. Volatile pollutant aliquots 
must be combined in the laboratory immediately before analysis.
    B. Effluent sample collection need not be delayed to compensate for 
hydraulic detention unless the POTW elects to include detention time 
compensation or unless the Approval Authority requires detention time 
compensation. The Approval Authority may require that each effluent 
sample is taken approximately one detention time later than the 
corresponding influent sample when failure to do so would result in an 
unrepresentative portrayal of actual POTW operation. The detention 
period should be based on a 24-hour average daily flow value. The 
average daily flow should in turn be based on the average of the daily 
flows during the same month of the previous year.

                             II. Grab Method

    If composite sampling is not an appropriate technique, grab samples 
should be taken to obtain influent and effluent operational data. A grab 
sample is an individual sample collected over a period of time not 
exceeding 15 minutes. The collection of influent grab samples should 
precede the collection of effluent samples by approximately one 
detention period except that where the detention period is greater than 
24 hours such staggering of the sample collection may not be necessary 
or appropriate. The detention period should be based on a 24-hour 
average daily flow value. The average daily flow should in turn be based 
upon the average of the daily flows during the same month of the 
previous year. Grab sampling should be employed where the pollutants 
being evaluated are those, such as cyanide and phenol, which may not be 
held for an extended period because of biological, chemical or physical

    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in part 401 of this chapter shall 
apply to this subpart.
    (b) The term ``BOD5 input'' shall mean the biochemical oxygen demand 
of the materials entered into process. It can be calculated by 
multiplying the fats, proteins and carbohydrates by factors of 0.890, 
1.031 and 0.691 respectively. Organic acids (e.g., lactic acids) should 
be included as carbohydrates. Composition of input materials may be 
based on either direct analyses or generally accepted published values.



Sec.  405.12  Effluent limitations guidelines representing the degree of 
effluent reduction attainable by the application of the best practicable
control technology currently available.

    Except as provided in Sec. Sec.  125.30 through 125.32, any existing

rate or pollutant mass loading rate which is excessive over any time 
period during the peak load at a POTW. Excessive discharges are defined 
as those in which the flow of BOD5 or total suspended solids (TSS) 
exceed the respective values of P from the following formula:

P = K(Q + R)-S

where:

P = maximum allowable peak waste load for the new corn wet milling 
          source to be discharged to the POTW (gallons per one hour for 
          flow and pounds per day for BOD5 and TSS).
Q = average existing waste load to POTW.
R = average waste load for the new corn wet milling source to be 
          discharged to POTW.
S = existing peak load of POTW.
K = 2. When the ratio of (S/Q) is greater than 1.5, K = 3.

    Calculations are to be based on dry weather conditions.

Sec.  409.20  Applicability; description of the crystalline cane sugar refining
subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the processing of raw cane sugar into crystalline refined 
sugar.



Sec.  409.21  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in part 401 of this chapter shall 
apply to this subpart.
    (b) Net shall mean the addition of pollutants.
    (c) Melt shall mean that amount of raw material (raw sugar) 
contained within aqueous solution at the beginning of the process for 
production of refined cane sugar.



Sec.  409.22  Effluent limitations guidelines representing the degree of effluent 
reduction attainable by the application of the best practicable control 
          technology currently available.

    Except as provided in Sec. Sec.  125.30 through 125.32, any existing 
point source subject to this subpart shall achieve the following 
effluent limitations representing the degree of effluent reduction 
attainable by the application of the best practicable control technology 
currently available (BPT):
    (a) Any crystalline cane sugar refinery discharging both barometric 
condenser cooling water and other process waters shall meet the 
following limitations. The BOD5 limitation is determined by the addition 
of the net BOD5 attributed to the barometric condenser cooling water to 
that amount of BOD5 attributed to the treated process water. The TSS 
limitation is that amount of TSS attributed to the treated process 
water. Where the barometric condenser cooling water and process water 
streams are mixed and impossible to measure separately prior to 
discharge, the values should be considered net.

Sec.  412.4  Best management practices (BMPs) for land application of manure, 
litter, and process wastewater.

    (a) Applicability. This section applies to any CAFO subject to 
subpart C of this part (Dairy and Beef Cattle other than Veal Calves) or 
subpart D of this part (Swine, Poultry, and Veal Calves).
    (b) Specialized definitions. (1) Setback means a specified distance 
from surface waters or potential conduits to surface

[[Page 199]]

waters where manure, litter, and process wastewater may not be land 
applied. Examples of conduits to surface waters include but are not 
limited to: Open tile line intake structures, sinkholes, and 
agricultural well heads.
    (2) Vegetated buffer means a narrow, permanent strip of dense 
perennial vegetation established parallel to the contours of and 
perpendicular to the dominant slope of the field for the purposes of 
slowing water runoff, enhancing water infiltration, and minimizing the 
risk of any potential nutrients or pollutants from leaving the field and 
reaching surface waters.
    (3) Multi-year phosphorus application means phosphorus applied to a 
field in excess of the crop needs for that year. In multi-year 
phosphorus applications, no additional manure, litter, or process 
wastewater is applied to the same land in subsequent years until the 
applied phosphorus has been removed from the field via harvest and crop 
removal.
    (c) Requirement to develop and implement best management practices. 
Each CAFO subject to this section that land applies manure, litter, or 
process wastewater, must do so in accordance with the following 
practices:
    (1) Nutrient Management Plan. The CAFO must develop and implement a 
nutrient management plan that incorporates the requirements of 
paragraphs (c)(2) through (c)(5) of this section based on a field-
specific assessment of the potential for nitrogen and phosphorus 
transport from the field and that addresses the form, source, amount, 
timing, and method of application of nutrients on each field to achieve 
realistic production goals, while minimizing nitrogen and phosphorus 
movement to surface waters.
    (2) Determination of application rates. Application rates for 
manure, litter, and other process wastewater applied to land under the 
ownership or operational control of the CAFO must minimize phosphorus 
and nitrogen transport from the field to surface waters in compliance 
with the technical standards for nutrient management established by the 
Director. Such technical standards for nutrient management shall:
    (i) Include a field-specific assessment of the potential for 
nitrogen and phosphorus transport from the field to surface waters, and 
address the form, source, amount, timing, and method of application of 
nutrients on each field to achieve realistic production goals, while 
minimizing nitrogen and phosphorus movement to surface waters; and
    (ii) Include appropriate flexibilities for any CAFO to implement 
nutrient management practices to comply with the technical standards, 
including consideration of multi-year phosphorus application on fields 
that do not have a high potential for phosphorus runoff to surface 
water, phased implementation of phosphorus-based nutrient management, 
and other components, as determined appropriate by the Director.
    (3) Manure and soil sampling. Manure must be analyzed a minimum of 
once annually for nitrogen and phosphorus content, and soil analyzed a 
minimum of once every five years for phosphorus content. The results of 
these analyses are to be used in determining application rates for 
manure, litter, and other process wastewater.
    (4) Inspect land application equipment for leaks. The operator must 
periodically inspect equipment used for land application of manure, 
litter, or process wastewater.
    (5) Setback requirements. Unless the CAFO exercises one of the 
compliance alternatives provided for in paragraph (c)(5)(i) or 
(c)(5)(ii) of this section, manure, litter, and process wastewater may 
not be applied closer than 100 feet to any down-gradient surface waters, 
open tile line intake structures, sinkholes, agricultural well heads, or 
other conduits to surface waters.
    (i) Vegetated buffer compliance alternative. As a compliance 
alternative, the CAFO may substitute the 100-foot setback with a 35-foot 
wide vegetated buffer where applications of manure, litter, or process 
wastewater are prohibited.
    (ii) Alternative practices compliance alternative. As a compliance 
alternative, the CAFO may demonstrate that a setback or buffer is not 
necessary because implementation of alternative conservation practices 
or field-specific conditions will provide pollutant reductions 
equivalent or better than the

[[Page 200]]

reductions that would be achieved by the 100-foot setback.

available technology economically achievable (BAT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart must achieve the following effluent 
limitations representing the application of BAT:
    (a) For CAFO production areas: the CAFO shall attain the same 
limitations and requirements as Sec.  412.43(a).
    (b) For CAFO land application areas: the CAFO shall attain the same 
limitations and requirements as Sec.  412.43(b).



Sec.  412.46  New source performance standards (NSPS).

    Any new source subject to this subpart must achieve the following 
effluent limitations representing the application of NSPS:
    (a) For CAFO production areas. There must be no discharge of manure, 
litter, or process wastewater pollutants into waters of the U.S. from 
the production area, subject to paragraphs (a)(1) through (a)(3) of this 
section.
    (1) Any CAFO subject to this subpart may request that the Director 
establish NPDES permit best management practice effluent limitations 
designed to ensure no discharge of manure, litter, or process wastewater 
based upon a site-specific evaluation of the CAFO's open surface manure 
storage structure. The NPDES permit best management practice effluent 
limitations must address the CAFO's entire production area. In the case 
of any CAFO using an open surface manure storage structure for which the 
Director establishes such effluent limitations, ``no discharge of 
manure, litter, or process wastewater pollutants,'' as used in this 
section, means that the storage structure is designed, operated, and 
maintained in accordance with best management practices established by 
the Director on a site-specific basis after a technical evaluation of 
the storage structure. The technical evaluation must address the 
following elements:
    (i) Information to be used in the design of the open manure storage 
structure including, but not limited to, the following: minimum storage 
periods for rainy seasons, additional minimum capacity for chronic 
rainfalls, applicable technical standards that prohibit or otherwise 
limit land application to frozen, saturated, or snow-covered ground, 
planned emptying and dewatering schedules consistent with the CAFO's 
Nutrient Management Plan, additional storage capacity for manure 
intended to be transferred to another recipient at a later time, and any 
other factors that would affect the sizing of the open manure storage 
structure.
    (ii) The design of the open manure storage structure as determined 
by the most recent version of the National Resource Conservation 
Service's Animal Waste Management (AWM) software. CAFOs may use 
equivalent design software or procedures as approved by the Director.
    (iii) All inputs used in the open manure storage structure design 
including actual climate data for the previous 30 years consisting of 
historical average monthly precipitation and evaporation values, the 
number and types of animals, anticipated animal sizes or weights, any 
added water and bedding, any other process wastewater, and the size and 
condition of outside areas exposed to rainfall and contributing runoff 
to the open manure storage structure.
    (iv) The planned minimum period of storage in months including, but 
not limited to, the factors for designing an open manure storage 
structure listed in paragraph (a)(1)(i) of this section. Alternatively 
the CAFO may determine the minimum period of storage by specifying times 
the storage pond will

[[Page 206]]

be emptied consistent with the CAFO's Nutrient Management Plan.
    (v) Site-specific predicted design specifications including 
dimensions of the storage facility, daily manure and wastewater 
additions, the size and characteristics of the land application areas, 
and the total calculated storage period in months.
    (vi) An evaluation of the adequacy of the designed manure storage 
structure using the most recent version of the Soil Plant Air Water 
(SPAW) Hydrology Tool. The evaluation must include all inputs to SPAW 
including but not limited to daily precipitation, temperature, and 
evaporation data for the previous 100 years, user-specified soil 
profiles representative of the CAFO's land application areas, planned 
crop rotations consistent with the CAFO's Nutrient Management Plan, and 
the final modeled result of no overflows from the designed open manure 
storage structure. For those CAFOs where 100 years of local weather data 
for the CAFO's location is not available, CAFOs may use a simulation 
with a confidence interval analysis conducted over a period of 100 
years. The Director may approve equivalent evaluation and simulation 
procedures.
    (vii) The Director may waive the requirement of (a)(1)(vi) for a 
site-specific evaluation of the designed manure storage structure and 
instead authorize a CAFO to use a technical evaluation developed for a 
class of specific facilities within a specified geographical area.
    (viii) Waste management and storage facilities designed, 
constructed, operated, and maintained consistent with the analysis 
conducted in paragraphs (a)(1)(i) through (a)(1)(vii) of this section 
and operated in accordance with the additional measures and records 
required by Sec.  412.47(a) and (b), will fulfill the requirements of 
this section.
    (ix) The Director has the discretion to request additional 
information to support a request for effluent limitations based on a 
site-specific open surface manure storage structure.
    (2) The production area must be operated in accordance with the 
additional measures required by Sec.  412.47(a) and (b).
    (3) Provisions for upset/bypass, as provided in 40 CFR 122.41(m)-
(n), apply to a new source subject to this provision.
    (b) For CAFO land application areas: the CAFO shall attain the same 
limitations and requirements as Sec.  412.43(b)(1).
    (c) The CAFO shall attain the limitations and requirements of this 
paragraph as of the date of permit coverage.
    (d) Any source subject to this subpart that commenced discharging 
after April 14, 1993, and prior to April 14, 2003, which was a new 
source subject to the standards specified in Sec.  412.15, revised as of 
July 1, 2002, must continue to achieve those standards for the 
applicable time period specified in 40 CFR 122.29(d)(1). Thereafter, the 
source must achieve the standards specified in Sec.  412.43(a) and (b).
    (e) Any source subject to this subpart that commenced discharging 
after April 14, 2003, and prior to January 20, 2009, which was a new 
source subject to the standards specified in Sec.  412.46(a) through (d) 
in the July 1, 2008, edition of 40 CFR part 439, must continue to 
achieve those standards for the applicable time period specified in 40 
CFR 122.29(d)(1).

Sec.  412.47  Additional measures.

    (a) Each CAFO subject to this subpart must implement the 
requirements of Sec.  412.37(a).
    (b) Each CAFO subject to this subpart must comply with the record-
keeping requirements of Sec.  412.37(b).
    (c) Each CAFO subject to this subpart must comply with the record-

    (a) In lieu of monitoring for TTO, the control authority may allow 
industrial users of POTWs to make the following certification as a 
comment to the periodic reports required by Sec.  403.12(e): ``Based on 
my inquiry of the person or persons directly responsible for managing 
compliance with the pretreatment standard for total toxic organics 
(TTO), I certify that, to the best of my knowledge and belief, no 
dumping of concentrated toxic organics into the wastewaters has occurred 
since filing the last discharge monitoring report. I further certify 
that this facility is implementing the toxic organic management plan 
submitted to the control authority.''
    (b) In requesting that no monitoring be required industrial users of 
POTWs shall submit a toxic organic management plan that specifies to the 
control authority's satisfaction the toxic organic compounds used; the 
method of disposal used instead of dumping, such as reclamation, 
contract hauling, or incineration; and procedures for assuring that 
toxic organics do not routinely spill or leak into the wastewater.
    (c) If monitoring is necessary to measure compliance with the TTO 
standard the industrial user need analyze only for those pollutants 
which would reasonably be expected to be present.

Sec.  414.10  General definitions.

    As used in this part:
    (a) Except as provided in this regulation, the general definitions, 
abbreviations and methods of analysis set forth in part 401 of this 
chapter shall apply to this part.
    (b) Pretreatment control authority means:
    (1) The POTW if the POTW's submission for its pretreatment program 
has been approved in accordance with the requirements of 40 CFR 403.11, 
or
    (2) The Approval Authority if the submission has not been approved.
    (c) Priority pollutants means the toxic pollutants listed in 40 CFR 
401.15.



Sec.  414.11  Applicability.

    (a) The provisions of this part are applicable to process wastewater 
discharges from all establishments or portions of establishments that 
manufacture the organic chemicals, plastics, and synthetic fibers 
(OCPSF) products or product groups covered by subparts B through H of 
this regulation and are included within the following U.S. Department of 
Commerce Bureau of the Census Standard Industrial Classification (SIC) 
major groups:
    (1) SIC 2821--Plastic Materials, Synthetic Resins, and 
Nonvulcanizable Elastomers,
    (2) SIC 2823--Cellulosic Man-Made Fibers,
    (3) SIC 2824--Synthetic Organic Fibers, Except Cellulosic,
    (4) SIC 2865--Cyclic Crudes and Intermediates, Dyes, and Organic 
Pigments,
    (5) SIC 2869--Industrial Organic Chemicals, Not Elsewhere 
Classified.
    (b) The provisions of this part are applicable to wastewater 
discharges from OCPSF research and development, pilot plant, technical 
service and laboratory bench scale operations if such operations are 
conducted in conjunction with and related to existing OCPSF 
manufacturing activities at the plant site.
    (c) Notwithstanding paragraph (a) of this section, the provisions of 
this part are not applicable to discharges resulting from the 
manufacture of OCPSF products if the products are included in the 
following SIC subgroups and have in the past been reported by the 
establishment under these subgroups and not under the SIC groups listed 
in paragraph (a) of this section:
    (1) SIC 2843085--bulk surface active agents;
    (2) SIC 28914--synthetic resin and rubber adhesives;
    (3) Chemicals and Chemical Preparations, not Elsewhere Classified:
    (i) SIC 2899568--sizes, all types
    (ii) SIC 2899597--other industrial chemical specialties, including 
fluxes,

plastic wood preparations, and embalming fluids;
    (4) SIC 2911058--aromatic hydrocarbons manufactured from purchased 
refinery products; and
    (5) SIC 2911632--aliphatic hydrocarbons manufactured from purchased 
refinery products.
    (d) Notwithstanding paragraph (a) of this section, the provisions of 
this part are not applicable to any discharges for which a different set 
of previously promulgated effluent limitations guidelines and standards 
in this subchapter apply, unless the facility reports OCPSF products 
under SIC codes 2865, 2869, or 2821, and the facility's OCPSF 
wastewaters are treated in a separate treatment system or discharged 
separately to a publicly owned treatment works.
    (e) The provisions of this part do not apply to any process 
wastewater discharges from the manufacture of organic chemical compounds 
solely by extraction from plant and animal raw materials or by 
fermentation processes.
    (f) Discharges of chromium, copper, lead, nickel, and zinc in 
``complexed metal-bearing waste streams,'' listed in appendix B of this 
part, are not subject to the requirements of this part.
    (g) Non-amenable cyanide. Discharges of cyanide in ``cyanide-bearing 
waste streams'' (listed in appendix A to this part) are not subject to 
the cyanide limitations and standards of this part if the permit writer 
or control authority determines that the cyanide limitations and 
standards are not achievable due to elevated levels of non-amenable 
cyanide (i.e., cyanide that is not oxidized by chlorine treatment) that 
result from the unavoidable complexing of cyanide at the process source 
of the cyanide-bearing waste stream and establishes an alternative total 
cyanide or amenable cyanide limitation that reflects the best available 
technology economically achievable. The determination must be based upon 
a review of relevant engineering, production, and sampling and analysis 
information, including measurements of both total and amenable cyanide 
in the waste stream. An analysis of the extent of complexing in the 
waste stream, based on the foregoing information, and its impact on 
cyanide treatability shall be set forth in writing and, for direct 
dischargers, be contained in the fact sheet required by 40 CFR 124.8.
    (h) Allowances for non-metal-bearing waste streams. Discharge 
limitations for chromium, copper, lead, nickel, and zinc or discharge 
standards for lead and zinc may be established for waste streams not 
listed in appendix A of this part and not otherwise determined to be 
``metal-bearing waste streams'' if the permit writer or control 
authority determines that the wastewater metals contamination is due to 
background levels that are not reasonably avoidable from sources such as 
intake water, corrosion of construction materials or contamination of 
raw materials. The determination must be based upon a review of relevant 
plant operating conditions, process chemistry, engineering, and sampling 
and analysis information. An analysis of the sources and levels of the 
metals, based on the foregoing information, shall be set forth in 
writing; for direct dischargers, the analysis shall be contained in the 
fact sheet required by 40 CFR 124.8. For direct dischargers, the permit 
writer may establish limitations for chromium, copper, lead, nickel, and 
zinc for non-``metal-bearing waste streams'' between the lowest level 
which the permit writer determines based on best professional judgment 
can be reliably measured and the concentrations of such metals present 
in the wastestreams, but not to exceed the applicable limitations 
contained in Sec. Sec.  414.91 and 414.101. (For zinc, the applicable 
limitations which may not be exceeded are those appearing in the tables 
in Sec. Sec.  414.91 and 414.101, not the alternative limitations for 
rayon fiber manufacture by the viscose process and the acrylic fiber 
manufacture by the zinc chloride/solvent process set forth in footnote 2 
to each of these tables.) For indirect dischargers, the control 
authority may establish standards for lead and zinc for non-``metal-
bearing waste streams'' between the lowest level which the control 
authority determines based on best professional judgment can be reliably 
measured and the concentration of such metals present in the 
wastestreams, but not to

[[Page 225]]

exceed the applicable standards contained in Sec. Sec.  414.25, 414.35, 
414.45, 414.55, 414.65, 414.75, and 414.85. (For zinc, the applicable 
standards which may not be exceeded are those appearing in the tables in 
the above referenced sections, not the alternative standards for rayon 
filber manufacture by the viscose process set forth in footnote 2 to the 
table in Sec.  414.25, or the alternative standards for acrylic fiber 
manufacture by the zinc chloride/solvent process set forth in footnote 2 
to the table in Sec.  414.35.) The limitations and standards for 
individual dischargers shall be set on a mass basis by multiplying the 
concentration allowance established by the permit writer or control 
authority by the process wastewater flow from the individual 
wastestreams for which incidental metals have been found to be present.
    (i) BOD5 and TSS limitations for plants with production 
in two or more subcategories. Any existing or new source direct 
discharge point source subject to two or more of subparts B through H 
must achieve BOD5 and TSS discharges not exceeding the 
quantity (mass) determined by multiplying the total OCPSF process 
wastewater flow subject to subparts B through H times the following 
``OCPSF production-proportioned concentration'': For a specific plant, 
let wj be the proportion of the plant's total OCPSF 
production in subcategory j. Then the plant-specific production-
proportioned concentration limitations are given by:
[GRAPHIC] [TIFF OMITTED] TC15NO91.016


The ``BOD5 Limitj'' and ``TSS Limitj'' 
are the respective subcategorical BOD5 and TSS Maximum for 
Any One Day or Maximum for Monthly Average limitations.

Subpart I_Direct Discharge Point Sources That Use End-of-Pipe Biological 
                                Treatment



Sec.  414.90  Applicability; description of the subcategory of direct discharge
point sources that use end-of-pipe biological treatment.

    The provisions of this subpart are applicable to the process 
wastewater discharges resulting from the manufacture of the OCPSF 
products and product groups defined by Sec.  414.11 from any point 
source that uses end-of-pipe biological treatment or installs end-of-
pipe biological treatment to comply with BPT effluent limitations.



Sec.  414.91  Toxic pollutant effluent limitations and standards for direct discharge
point sources that use end-of-pipe biological treatment.

    (a) Any point source subject to this subpart must achieve discharges 
not exceeding the quantity (mass) determined by multiplying the process 
wastewater flow subject to this subpart times the concentrations in the 
following table.
    (b) In the case of chromium, copper, lead, nickel, zinc, and total 
cyanide, the discharge quantity (mass) shall be determined by 
multiplying the concentrations listed in the following table for these 
pollutants times the flow from metal-bearing waste streams for the 
metals and times the flow from cyanide bearing waste streams for total 
cyanide. The metal-bearing waste streams and cyanide-bearing waste 
streams are defined as those waste streams listed in appendix A of this 
part, plus any additional OCPSF process wastewater streams identified by 
the permitting authority on a case-by-case basis as metal or cyanide 
bearing based upon a determination that such streams contain significant 
amounts of the pollutants identified above. Any such streams designated 
as metal or cyanide bearing must be treated independently of other metal 
or cyanide bearing waste streams unless the permitting authority 
determines that the combination of such streams, prior to treatment, 
with the appendix A waste streams will result in substantial reduction 
of these pollutants. This determination must be based upon a review of 
relevant engineering, production, and sampling and analysis information.

  Subpart J_Direct Discharge Point Sources That Do Not Use End-of-Pipe 
                          Biological Treatment



Sec.  414.100  Applicability; description of the subcategory of direct discharge
point sources that do not use end-of-pipe biological treatment.

    The provisions of this subpart are applicable to the process 
wastewater discharges resulting from the manufacture of the OCPSF 
products and product groups defined by Sec.  414.11 from any point 
source that does not use end-of-pipe biological treatment and does not 
install end-of-pipe biological treatment to comply with BPT effluent 
limitations.



Sec.  414.101  Toxic pollutant effluent limitations and standards for direct discharge
point sources that do not use end-of-pipe biological treatment.

    (a) Any point source subject to this subpart must achieve discharges 
not exceeding the quantity (mass) determined by multiplying the process 
wastewater flow subject to this subpart times the concentartions in the 
following table.
    (b) In the case of chromium, copper, lead, nickel, zinc, and total 
cyanide, the discharge quantity (mass) shall be determined by 
multiplying the concentrations listed in the following table for these 
pollutants times the flow from metal bearing waste streams for the 
metals and times the cyanide-bearing waste streams for total cyanide. 
The metal-bearing waste streams and cyanide-bearing waste streams are 
defined as those waste streams listed in appendix A of this part, plus 
any additional OCPSF process wastewater streams identified by the 
permitting authority on a case-by-case basis as metal or cyanide bearing 
based upon a determination that such streams contain significant amounts 
of the pollutants identified above. Any such streams designated as metal 
or cyanide bearing must be treated independently of other metal or 
cyanide bearing waste streams unless the permitting authority determines 
that the combination of such streams, prior to treatment, with the 
Appendix A waste streams will result in substantial reduction of these 
pollutants. This determination must be based upon a review of relevant 
engineering, production, and sampling and analysis information.

       Subpart O_Manufacture of Spray Dried Detergents Subcategory



Sec.  417.150  Applicability; description of the manufacture of spray dried 
detergents subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from all operations associated with the manufacture of spray 
dried detergents, including but not limited to assembly and storage of 
raw materials, crutching, spray drying, blending (including tumble 
spraying of additives) and packaging.



Sec.  417.151  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in 40 CFR part 401 shall apply to this 
subpart.
    (b) The term anhydrous product shall mean the theoretical product 
that

[[Page 328]]

would result if all water were removed from the actual product.
    (c) The term surfactant shall mean those methylene blue active 
substances amenable to measurement by the method described in ``Methods 
for Chemical Analysis of Water and Wastes,'' 1971, Environmental 
Protection Agency, Analytical Quality Control Laboratory, page 131.
    (d) The term normal operation of a spray tower shall mean operation 
utilizing formulations that present limitted air quality problems from 
stack gases and associated need for extensive wet scrubbing, and without 
more than 6 turnarounds in a 30 consecutive day period, thus permitting 
essentially complete recycle of waste water.
    (e) The term air quality restricted operation of a spray tower shall 
mean an operation utilizing formulations (e.g., those with high non-
ionic content) which require a very high rate of wet scrubbing to 
maintain desirable quality of stack gases, and thus generate much 
greater quantities of waste water than can be recycled to process.
    (f) The term fast turnaround operation of a spray drying tower shall 
mean operation involving more than 6 changes of formulation in a 30 
consecutive day period that are of such degree and type (e.g., high 
phosphate to no phosphate) as to require cleaning of the tower to 
maintain minimal product quality.
    (g) The term BOD7 shall mean the biochemical oxygen demand as 
determined by incubation at 20 degrees C for a period of 7 days using an 
acclimated seed. Agitation employing a magnetic stirrer set at 200 to 
500 rpm may be used.

Sec.  418.11  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in 40 CFR part 401 shall apply to this 
subpart.
    (b) The term process wastewater 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, by-product, or waste product. The term ``process 
wastewater'' does not include contaminated non-process wastewater, as 
defined below.
    (c) The term, contaminated non-process wastewater shall mean any 
water including precipitation runoff which, during manufacturing or 
processing, comes into incidental contact with any raw material, 
intermediate product, finished product, by-product or waste product by 
means of: (1) Precipitation runoff; (2) accidental spills; (3) 
accidental leaks caused by the failure of process equipment and which 
are repaired or the discharge of pollutants therefrom contained or 
terminated within the shortest reasonable time which shall not exceed 24 
hours after discovery or when discovery should reasonably have been 
made, whichever is earliest; and (4) discharges from safety showers and 
related personal safety equipment, and from equipment washings for the 
purpose of safe entry, inspection and maintenance; provided that all 
reasonable measures have been taken to prevent, reduce, eliminate and 
control to the maximum extent feasible such contact and provided further 
that all reasonable measures have been taken that will mitigate the 
effects of such contact once it has occurred.
    (d) The term ten-year 24-hour rainfall event shall mean the maximum 
24-hour precipitation event with a probable recurrence interval of once 
in 10 years as defined by the National Weather Service in technical 
paper No. 40, ``Rainfall Frequency Atlas of the United States'', May 
1961, and subsequent amendments in effect as of the effective date of 
this regulation.
    (e) The term 25-year 24-hour rainfall event shall mean the maximum 
24-hour precipitation event with a probable recurrence interval of once 
in 25 years as defined by the National Weather Service in technical 
paper No. 40, ``Rainfall Frequency Atlas of the United States'', May 
1961, and subsequent amendments in effect, as of the effective date of 
this regulation.
    (f) The term calcium sulfate storage pile runoff shall mean the 
calcium sulfate transport water runoff from or through the calcium 
sulfate pile, and the precipitation which falls directly on the storage 
pile and which may be collected in a seepage ditch at the base of the 
outer slopes of the storage pile, provided such seepage ditch is 
protected from the incursion of surface runoff from areas outside of the 
outer perimeter of the seepage ditch.

    (c)(1) In addition to the provisions contained above pertaining to 
COD, ammonia and sulfide, any existing point source subject to this 
subpart must achieve the following effluent limitations representing the 
degree of effluent reduction attainable by the application of the best 
available technology economically achievable (BAT):
    (i) For each of the regulated pollutant parameters listed below, the 
effluent limitation for a given refinery is the sum of the products of 
each effluent limitation factor times the applicable process feedstock 
rate, calculated as provided in 40 CFR 122.45(b). Applicable production 
processes are presented in appendix A, by process type. The process 
identification numbers presented in this appendix A are for the 
convenience of the reader. They can be cross-referenced in the

water, are excluded from the discharge allowed by paragraph (b) of this 
section. Once-through cooling water may be discharged with a total 
organic carbon concentration not to exceed 5 mg/l.
    (e) Effluent limitations for contaminated runoff. The following 
effluent limitations constitute the quantity and quality of pollutants 
or pollutant properties controlled by this paragraph and attributable to 
contaminated runoff, which may be discharged after the application of 
the best practicable control technology currently available by a point 
source subject to this subpart.
    (1) If wastewater consists solely of contaminated runoff and is not 
commingled or treated with process wastewater, it may be discharged if 
it does not exceed 15 mg/l oil and grease and 110 mg/l total organic 
carbon (TOC) based upon an analysis of any single grab or composite 
sample.
    (2) If contaminated runoff is commingled or treated with process 
wastewater, or if wastewater consisting solely of contaminated runoff 
which exceeds 15 mg/l oil and grease or 110 mg/l TOC is not commingled 
or treated with any other type of wastewater, the quantity of pollutants 
discharged shall not exceed the quantity determined by multiplying the 
flow of contaminated runoff as determined by the permit writer times the 
concentrations listed in the following table:

\1\ In any case in which the applicant can demonstrate that the chloride
  ion concentration in the effluent exceeds 1,000 mg/l (1,000 ppm), the
  permitting authority may substitute TOC as a parameter in lieu of COD.
  A TOC effluent limitation shall be based on effluent data from the
  particular refinery which correlates TOC to BOD5. If in the judgment
  of the permitting authority, adequate correlation data are not
  available, the effluent limitations for TOC shall be established at a
  ratio of 2.2 to 1 to the applicable effluent limitations for BOD5.

Notes:
See table Sec.   419.42(b)(2) for process factor. Process factor = 0.88.
See table Sec.   419.42(b)(1) for size factor for 125,000 bbl per stream day lube refinery. Size factor = 0.97.
To calculate the limits for each parameter, multiply the limit Sec.   419.42(a) by both the process factor and
  size factor. BOD5 limit (maximum for any 1 day) = 17.9 x 0.88 x 0.97 = 15.3 lb. per 1,000 bbl of feedstock.

    (c) The provisions of Sec.  419.12(c) apply to discharges of process 
wastewater pollutants attributable to ballast water by a point source 
subject to the provisions of this subpart.
    (d) The quantity and quality of pollutants or pollutant properties 
controlled by this paragraph, attributable to once-through cooling 
water, are excluded from the discharge allowed by paragraph (b) of this 
section. Once-through cooling water may be discharged with a total 
organic carbon concentration not to exceed 5 mg/l.
    (e) Effluent limitations for contaminated runoff. The following 
effluent limitations constitute the quantity and quality of pollutants 
or pollutant properties controlled by this paragraph and attributable to 
contaminated runoff, which may be discharged after the application of 
the best practicable control technology currently available by a point 
source subject to this subpart.
    (1) If wastewater consists solely of contaminated runoff and is not 
commingled or treated with process wastewater, it may be discharged if 
it does not exceed 15 mg/l oil and grease and 110 mg/l total organic 
carbon (TOC) based upon an analysis of any single grab or composite 
sample.
    (2) If contaminated runoff is commingled or treated with process 
wastewater, or if wastewater consisting solely of contaminated runoff 
which exceeds 15 mg/l oil and grease or 110 mg/l TOC is not commingled 
or treated with any other type of wastewater, the quantity of pollutants 
discharged shall not exceed the quantity determined by multiplying the 
flow of contaminated runoff as determined by the permit writer times the 
concentrations listed in the following table:

\1\ In any case in which the applicant can demonstrate that the chloride
  ion concentration in the effluent exceeds 1,000 mg/l (1,000 ppm), the
  permitting authority may substitute TOC as a parameter in lieu of COD.
  A TOC effluent limitation shall be based on effluent data from the
  particular refinery which correlates TOC to BOD5. If in the judgment
  of the permitting authority, adequate correlation data are not
  available, the effluent limitations for TOC shall be established at a
  ratio of 2.2 to 1 to the applicable effluent limitations for BOD5.

\1\ The request for alternative effluent limitations for these plants
  are for indirect discharges to POTWs

    (2) The information to be submitted with the request for 
consideration of alternative effluent limitations is to include:
    (i) A schematic diagram of the existing wastewater treatment 
facility showing each source of wastewater, cooling water, and other 
waters entering the treatment facility; discharge and recycle flow rates 
for each water source and each major treatment component;
    (ii) Existing monitoring data relating to discharges to and from the 
central treatment facility including pollutant concentrations, flows and 
mass loadings; As a minimum, monitoring data should be provided for a 
six month period of normal operation of the production and treatment 
facilities. The complete data as well as a data summary including the 
maximum, minimum, and mean gross discharge loadings and the standard 
deviation of the discharge loadings for each monitored pollutant should 
be provided. Any supplemental monitoring data for toxic pollutants 
should also be provided.
    (iii) A scale map of the area of the plant served by the wastewater 
treatment facility, including the treatment facility and water supply 
and discharge points;
    (iv) An estimate of the least costly investment required to meet the 
generally applicable limitations or standards for the facility and a 
description of such treatment system including schematic diagrams 
showing the major treatment system components and flow rates through the 
system. As a minimum, the cost estimates should be comprised of a single 
page summary for each water pollution control system

[[Page 392]]

showing estimated installed direct cost totals for mechanical equipment; 
piping and instrumentation; foundations and structural components; and, 
electrical components. Indirect costs for contingencies, overhead and 
profit, engineering fees, and any other indirect costs must be itemized 
separately. The sum of the direct and indirect costs which represents 
the owner's or operator's total estimate, must be shown.
    (v) The effluent limitations or standards which could be achieved if 
the discharger were to spend an amount equal to the Agency's model 
treatment system cost estimate for the facility and the treatment 
facilities which would be used to meet those limitations or standards. 
Schematic diagrams and cost estimates as outlined in paragraph 
(b)(2)(iv) of this section, should be provided for each treatment 
system; and,
    (vi) Production rates in tons per day for each process contributing 
wastewater to the central treatment facility consistent with those 
reported by the owner or operator in the NPDES permit application for 
the central treatment facility.
    (3) The request described in subsection (b)(1) of this section, must 
be based upon the owner's or operator's belief that the cost of bringing 
the specified central treatment facilities into compliance with the 
provisions of this part would require expenditures so high compared to 
the Agency's model treatment system cost estimate applicable to that 
facility that the applicable limitations or standards would not 
represent BPT, BAT, BCT, or PSES, as the case may be, for the facility.

Sec.  420.20  Applicability; description of the sintering subcategory.

    The provisions of this subpart are applicable to discharges and to 
the introduction of pollutants into publicly owned treatment works 
resulting from sintering operations conducted by the heating of iron 
bearing wastes (mill scale and dust from blast furnaces and steelmaking 
furnaces) together with fine iron ore, limestone, and coke fines in an 
ignition furnace to produce an agglomerate for charging to the blast 
furnace.



Sec.  420.21  Specialized definitions.

    As used in this subpart:
    (a) For the sintering subcategory, the term product means sinter 
agglomerated from iron-bearing materials.
    (b) The term dry air pollution control system means an emission 
control system that utilizes filters to remove iron-bearing particles 
(fines) from blast furnace or sintering off-gases.
    (c) The term minimum level (ML) means the level at which the 
analytical system gives recognizable signals and an acceptable 
calibration point. For 2,3,7,8-tetrachlorodibenzofuran, the minimum 
level is 10 pg/L per EPA Method 1613B for water and wastewater samples.
    (d) The term pg/L means picograms per liter (ppt = 1.0 x 10-12 gm/
L).
    (e) The term sintering means a process for agglomerating iron-
bearing materials into small pellets (sinter) that can be charged to a 
blast furnace.
    (f) The term wet air pollution control system means an emission 
control system that utilizes water to clean process or furnace off-
gases.

                    Subpart G_Hot Forming Subcategory



Sec.  420.70  Applicability; description of the hot forming subcategory.

    The provisions of this subpart are applicable to discharges and to 
the introduction of pollutants into publicly owned treatment works 
resulting from hot forming operations conducted in primary, section, 
flat, and pipe and tube mills.



Sec.  420.71  Specialized definitions.

    (a) The term hot forming means those steel operations in which 
solidified, heated steel is shaped by rolls.
    (b) The term primary mill means those steel hot forming operations 
that reduce ingots to blooms or slabs by passing the ingots between 
rotating steel rolls. The first hot forming operation performed on 
solidified steel after it is removed from the ingot molds is carried out 
on a ``primary mill''.
    (c) The term section mill means those steel hot forming operations 
that produce a variety of finished and semi-finished steel products 
other than the products of those mills specified below in paragraphs 
(d), (e), (g), and (h) of this section.
    (d) The term flat mill means those steel hot forming operations that 
reduce heated slabs to plates, strip and sheet, or skelp.
    (e) The term pipe and tube mill means those steel hot forming 
operations that produce butt welded or seamless tubular steel products.
    (f) The term scarfing means those steel surface conditioning 
operations in which flames generated by the combustion of oxygen and 
fuel are used to remove surface metal imperfections from slabs, billets, 
or blooms.
    (g) The term plate mill means those steel hot forming operations 
that produce flat hot-rolled products which are (1) between 8 and 48 
inches wide and over 0.23 inches thick; or (2) greater than 48 inches 
wide and over 0.18 inches thick.
    (h) The term hot strip and sheet mill means those steel hot forming 
operations that produce flat hot-rolled products other than plates.
    (i) The term specialty steel means those steel products containing 
alloying elements which are added to enhance the properties of the steel 
product when individual alloying elements (e.g., aluminum, chromium, 
cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, 
zirconium) exceed 3% or the total of all alloying elements exceed 5%.
    (j) The term carbon steel means those steel products other than 
specialty steel products.
    (k) The term carbon hot forming operation (or ``carbon'') means 
those hot forming operations which produce a majority, on a tonnage 
basis, of carbon steel products.
    (l) The term specialty hot forming operation (or ``specialty'') 
applies to all hot forming operations other than ``carbon hot forming 
operations.''



Sec.  420.72  Effluent limitations representing the degree of effluent reduction
attainable by the application of the best practicable control technology

Sec.  420.73  Effluent limitations representing the degree of effluent reduction
attainable by the application of the best available technology economically 
          achievable (BAT).

    The Agency has determined that there are not significant quantities 
of toxic pollutants in hot forming wastewaters after compliance with 
applicable BPT limitations. Accordingly, since the BPT level of 
treatment provides adequate control, the Agency is not promulgating more 
stringent BAT limitations.

Sec.  420.90  Applicability; description of the acid pickling subcategory.

    The provisions of this subpart are applicable to discharges and to 
the introduction of pollutants into publicly owned treatment works 
resulting from sulfuric acid, hydrochloric acid, or combination acid 
pickling operations.



Sec.  420.91  Specialized definitions.

    (a) The term sulfuric acid pickling means those operations in which 
steel products are immersed in sulfuric acid solutions to chemically 
remove oxides and scale, and those rinsing operations associated with 
such immersions.
    (b) The term hydrochloric acid pickling means those operations in 
which steel products are immersed in hydrochloric acid solutions to 
chemically remove oxides and scale, and those rinsing operations 
associated with such immersions.
    (c) The term combination acid pickling means those operations in 
which steel products are immersed in solutions of more than one acid to 
chemically remove scale and oxides, and those rinsing steps associated 
with such immersions.
    (d) The term fume scrubber means those pollution control devices 
used to remove and clean fumes originating in pickling operations.
    (e) The term batch means those pickling operations which process 
steel products such as coiled wire, rods, and tubes in discrete batches 
or bundles.
    (f) The term continuous means those pickling operations which 
process steel products other than in discrete batches or bundles.
    (g) The term acid recovery means those sulfuric acid pickling 
operations that include processes for recovering the unreacted acid from 
spent pickling acid solutions.
    (h) The term acid regeneration means those hydrochloric acid 
pickling operations that include processes for regenerating acid from 
spent pickling acid solutions.
    (i) The term neutralization means those acid pickling operations 
that do not include acid recovery or acid regeneration processes.
    (j) The term spent acid solution (or spent pickle liquor) means 
those solutions of steel pickling acids which have been used in the 
pickling process and are discharged or removed therefrom.
    (k) The term rod, wire and coil means those acid pickling operations 
that pickle rod, wire or coiled rod and wire products.
    (l) The term bar, billet and bloom means those acid pickling 
operations that pickle bar, billet or bloom products.
    (m) The term strip, sheet and plate means those acid pickling 
operations that pickle strip, sheet or plate products.

Sec.  420.100  Applicability; description of the cold forming subcategory.

    (a) The provisions of this subpart are applicable to discharges and 
to the introduction of pollutants into publicly owned treatment works 
from cold rolling and cold working pipe and tube operations in which 
unheated steel is passed through rolls or otherwise processed to reduce 
its thickness, to produce a smooth surface, or to develop controlled 
mechanical properties in the steel.
    (b) The limitations and standards set out below for cold worked pipe 
and tube operations shall be applicable only where cold worked pipe and 
tube wastewaters are discharged at steel plant sites. No limitations are 
applicable or allowable where these wastewaters are hauled off-site for 
disposal or are otherwise not discharged at steel plant sites. The 
limitations and standards set out below for cold worked pipe and tube 
operations shall be applicable only to the blowdown of soluble oil or 
water solutions used in cold worked pipe and tube forming operations. 
Limitations for other wastewater sources from these operations must be 
established on a site-specific basis.

[47 FR 23284, May 27, 1982, as amended at 49 FR 21034, May 17, 1984]



Sec.  420.101  Specialized definitions.

    (a) The term recirculation means those cold rolling operations which 
include recirculation of rolling solutions at all mill stands.
    (b) The term combination means those cold rolling operations which 
include recirculation of rolling solutions at one or more mill stands, 
and once-through use of rolling solutions at the remaining stand or 
stands.
    (c) The term direct application means those cold rolling operations 
which include once-through use of rolling solutions at all mill stands.
    (d) The term single stand means those recirculation or direct 
application cold rolling mills which include only one stand of work 
rolls.
    (e) The term multiple stands means those recirculation or direct 
application cold rolling mills which include more than one stand of work 
rolls.
    (f) The term cold worked pipe and tube means those cold forming 
operations that process unheated pipe and tube products using either 
water or oil solutions for cooling and lubrication.



Sec.  420.102  Effluent limitations representing the degree of effluent reduction 
attainable by the application of the best practicable control technology 
          currently available (BPT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart must achieve the following effluent 
limitations representing the degree of effluent reduction attainable by 
the application of the best practicable control technology currently 
available.

Sec.  420.110  Applicability; description of the alkaline cleaning subcategory.

    The provisions of this subpart are applicable to discharges and to 
the introduction of pollutants into publicly owned treatment works 
resulting from operations in which steel and steel products are immersed 
in alkaline cleaning baths to remove mineral and animal fats or oils 
from the steel, and those rinsing operations which follow such 
immersion.



Sec.  420.111  Specialized definitions.

    (a) The term batch means those alkaline cleaning operations which 
process steel products such as coiled wire, rods, and tubes in discrete 
batches or bundles.
    (b) The term continuous means those alkaline cleaning operations 
which process steel products other than in discrete batches or bundles.



Sec.  420.112  Effluent limitations representing the degree of effluent reduction
attainable by the application of the best practicable control technology 
          currently available (BPT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart must achieve the following effluent 
limitations representing the degree of effluent reduction attainable by 
the application of the best practicable control technology currently 
available.

                    Subpart L_Hot Coating Subcategory



Sec.  420.120  Applicability; description of the hot coating subcategory.

    (a) The provisions of this subpart are applicable to discharges and 
to the introduction of pollutants into publicly owned treatment works 
resulting from the operations in which steel is coated with zinc, terne 
metal, or other metals by the hot dip process, and those rinsing 
operations associated with that process.
    (b) The BPT and BAT limitations for zinc set out below are not 
applicable to hot coating operations with wastewater treatment 
facilities achieving, during periods of normal production, zinc 
discharge levels more stringent than those BPT and BAT limitations. For 
such operations, the BPT and BAT limitations for zinc shall be 
determined on a case-by-case basis based upon the existing performance 
of the wastewater treatment facility. The permitting authority shall 
evaluate representative effluent data from the wastewater treatment 
facility during

[[Page 448]]

periods of normal production in establishing the case-by-case BPT and 
BAT limitations. The BPT and BAT limitations specified in 40 CFR 420.122 
and 420.123 may be used as the basis for calculating total mass 
limitations for zinc pursuant to 40 CFR 420.03.

Sec.  420.121  Specialized definitions.

    (a) The term galvanizing means coating steel products with zinc by 
the hot dip process including the immersion of the steel product in a 
molten bath of zinc metal, and the related operations preceding and 
subsequent to the immersion phase.
    (b) The term terne coating means coating steel products with terne 
metal by the hot dip process including the immersion of the steel 
product in a molten bath of lead and tin metals, and the related 
operations preceding and subsequent to the immersion phase.
    (c) The term other coatings means coating steel products with metals 
other than zinc or terne metal by the hot dip process including the 
immersion of the steel product in a molten bath of metal, and the 
related operations preceding the subsequent to the immersion phase.
    (d) The term fume scrubber means wet air pollution control devices 
used to remove and clean fumes originating from hot coating operations.
    (e) The term strip, sheet, and miscellaneous products means steel 
products other than wire products and fasteners.
    (f) The term wire products and fasteners means steel wire, products 
manufactured from steel wire, and steel fasteners manufactured from

    Source: 67 FR 64268, Oct. 17, 2002, unless otherwise noted.



Sec.  420.130  Applicability.

    The provisions of this subpart are applicable to discharges to 
waters of the U.S. and the introduction of pollutants into publicly 
owned treatment works resulting from production of direct-reduced iron 
and from briquetting and forging operations.



Sec.  420.131  Specialized definitions.

    As used in this subpart:
    (a) The term briquetting operations means a hot or cold process that 
agglomerates (presses together) iron-bearing materials into small lumps 
without melting or fusion. Used as a concentrated iron ore substitute 
for scrap in electric furnaces.
    (b) The term direct-reduced iron (DRI) means iron produced by 
reduction of iron ore (pellets or briquettes) using gaseous (carbon 
monoxide-carbon dioxide, hydrogen) or solid reactants.
    (c) The term forging means the hot-working of heated steel shapes 
(e.g., ingots, blooms, billets, slabs) by hammering or hydraulic 
presses, performed at iron and steel mills.
    (d) For briquetting operations, the term product means the amount in 
tons of briquettes manufactured by hot or cold agglomeration processes.
    (e) For direct reduced iron (DRI), the term product means the amount 
of direct reduced iron and any fines that are produced and sold 
commercially (as opposed to fines that may be reprocessed on site).
    (f) For forging, the term product means the tons of finished steel 
forgings produced by hot working steel shapes.
    (g) The term O&G (as HEM) means total recoverable oil & grease 
measured as n-hexane extractable materials.

    Source: 49 FR 8800, Mar. 8, 1984, unless otherwise noted.



Sec.  421.40  Applicability: Description of the primary copper smelting subcategory.

    The provisions of this subpart apply to process wastewater 
discharges resulting from the primary smelting of copper from ore or ore 
concentrates. Primary copper smelting includes, but is not limited to, 
roasting, converting, leaching if preceded by a pyrometallurgical step, 
slag granulation and dumping, fire refining, and the casting of products 
from these operations.



Sec.  421.41  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 
apply to this subpart.
    (b) In the event that the waste streams covered by this subpart are 
combined for treatment or discharge with waste streams covered by 
Subparts E--Primary Electrolytic Copper Refining and/or Subpart I--
Metallurgical Acid Plants, the quantity of each pollutant or pollutant 
property discharged shall not exceed the quantity of each pollutant or 
pollutant property which could be discharged if each waste stream were 
discharged separately.
    (c) For all impoundments constructed prior to the effective date of 
the interim final regulation (40 FR 8513), the term ``within the 
impoundment,'' when used to calculate the volume of process wastewater 
which may be discharged, means the water surface area within the 
impoundment at maximum capacity plus the surface area of the inside and 
outside slopes of the impoundment dam as well as the surface area 
between the outside edge of the impoundment dam and any seepage ditch 
adjacent to the dam upon which rain falls and is returned to the 
impoundment. For the purpose of such calculations, the surface area 
allowances set forth above shall not exceed more than 30 percent of the 
water surface area within the impoundment dam at maximum capacity.
    (d) For all impoundments constructed on or after the effective date 
of the interim final regulation (the interim regulation was effective 
February 27, 1975; 40 FR 8513, February 27, 1975), the term ``within the 
impoundment,'' for purposes of calculating the volume of process 
wastewater which may be discharged, means the water surface area within 
the impoundment at maximum capacity.

    Source: 49 FR 8802, Mar. 8, 1984, unless otherwise noted.



Sec.  421.60  Applicability: Description of the secondary copper subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the recovery, processing, and remelting of new and used 
copper scrap and residues to produce copper metal and copper alloys, but 
are not applicable to continuous rod casting.



Sec.  421.61  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 
shall apply to this subpart.
    (b) For all impoundments constructed prior to the effective date of 
this regulation the term ``within the impoundment'' when used for 
purposes of calculating the volume of process wastewater which may be 
discharged shall mean the water surface area within the impoundment at 
maximum capacity plus the surface area of the inside and outside slopes 
of the impoundment dam as well as the surface area between the outside 
edge of the impoundment dam and any seepage ditch immediately adjacent 
to the dam upon which rain falls and is returned to the impoundment. For 
the purpose of such calculations, the surface area allowances set forth 
above shall not be

[[Page 481]]

more than 30 percent of the water surface area within the impoundment 
dam at maximum capacity.
    (c) For all impoundments constructed on or after the effective date 
of this regulation, the term ``within the impoundment'' for purposes of 
calculating the volume of process wastewater which may be discharged 
shall mean the water surface area within the impoundment at maximum 
capacity.
    (d) The term pond water surface area when used for the purpose of 
calculating the volume of wastewater which may be discharged shall mean 
the water surface area of the pond created by the impoundment for 
storage of process wastewater at normal operating level. This surface 
shall in no case be less than one-third of the surface area of the 
maximum amount of water which could be contained by the impoundment. The 
normal operating level shall be the average level of the pond during the 
preceding calendar month.



Sec.  421.62  Effluent limitations guidelines representing the degree of effluent
reduction attainable by the application of the best practicable control 
          technology currently available.

point source subject to this subpart shall achieve the following 
effluent limitations representing the degree of effluent reduction 
attainable by the application of the best practicable technology 
currently available: Subject to the provisions of paragraphs (b), (c), 
and (d) of this section, there shall be no discharge of process 
wastewater pollutants into navigable waters.
    (b) A process wastewater impoundment which is designed, constructed, 
and operated so as to contain the precipitation from the 10-year, 24-
hour rainfall event as established by the National Climatic Center, 
National Oceanic and Atmospheric Administration for the areas in which 
such impoundment is located may discharge that volume of process 
wastewater which is equivalent to the volume of precipitation that falls 
within the impoundment in excess of that attributable to the 10-year, 
24-hour rainfall event, when such event occurs.
    (c) During any calendar month there may be discharged from a process 
wastewater impoundment either a volume of process wastewater equal to 
the difference between the precipitation for the month that falls within 
the impoundment and either the evaporation from the pond water surface 
area for that month, or a volume of process wastewater equal to the 
difference between the mean precipitation for that month that falls 
within the impoundment and the mean evaporation from the pond water 
surface area as establsihed by the National Climatic Center, National 
Oceanic and Atmospheric Administration, for the area in which such 
impoundment is located (or as otherwise determined if no monthly data 
have been established by the National Climatic Center), whichever is 
greater.
    (d) Any process wastewater discharged pursuant to paragraph (c) of 
this section shall comply with each of the following requirements:

               Subpart A_Phosphorus Production Subcategory



Sec.  422.10  Applicability; description of the phosphorus production subcategory.

    The provisions of this subpart are applicable to discharges of 
pollutants resulting from the production of phosphorus and 
ferrophosphorus by smelting of phosphate ore.



               Subpart B_Phosphorus Consuming Subcategory



Sec.  422.20  Applicability; description of the phosphorus consuming subcategory.

    The provisions of this subpart are applicable to discharges of 
pollutants resulting from the manufacture of phosphoric acid, phosphorus 
pentoxide, phosphorus pentasulfide, phosphorus trichloride, and 
phosphorus oxychloride directly from elemental phosphorus. The 
production of phosphorus trichloride and phosphorus oxychloride creates 
waste water pollutants not completely amenable to the procedures 
utilized for best practicable control technology currently available. 
The standards set for phosphorus trichloride manufacture and phosphorus 
oxychloride manufacture, accordingly, must differ from the rest of the 
subcategory at this level of treatment.



                     Subpart C_Phosphate Subcategory



Sec.  422.30  Applicability; description of the phosphate subcategory.

    The provisions of this subpart are applicable to discharges of 
pollutants resulting from the manufacture of sodium tripolyphosphate, 
animal feed grade, calcium phosphate and human food grade calcium 
phosphate from phosphoric acid. The production of human food grade 
calcium phosphate creates waste water pollutants not completely amenable 
to the procedures utilized for best practicable control technology 
currently available. The standards set for human food grade calcium 
phosphates accordingly must differ from the rest of the subcategory at 
this level of treatment.

silica and other reagents.



Sec.  422.41  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 
shall apply to this subpart.
    (b) The term 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, by-product, or waste product. The term ``process waste 
water'' does not include contaminated nonprocess waste water, as defined 
below.
    (c) The term contaminated non-process waste water shall mean any 
water including precipitation runoff, which during manufacturing or 
processing, comes into incidental contact with any raw material, 
intermediate product, finished product, by-product or waste product by 
means of: (1) Precipitation runoff, (2) accidental spills, (3) 
accidental leaks caused by the failure of process equipment and which 
are repaired or the discharge of pollutants therefrom contained or 
terminated within the shortest reasonable time which shall not exceed 24 
hours after discovery or when discovery should reasonably have been 
made, whichever is earliest, and (4) discharges from safety showers and 
related personal safety equipment, and from equipment washings for the

    Source: 41 FR 25977, June 23, 1976, unless otherwise noted.



Sec.  422.50  Applicability; description of the defluorinated phosphoric acid 
subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the defluorination of phosphoric acid.

[[Page 642]]

Wet process phosphoric acid is dehydrated by application of heat and 
other processing acids such as vacuum and air stripping. The acid is 
concentrated up to 70-73% P2 O5 in the 
defluorination process.



Sec.  422.51  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 
shall apply to this subpart.
    (b) The term 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, by-product, or waste product. The term ``process waste 
water'' does not include contaminated non-process waste water, as 
defined below.
    (c) The term contaminated nonprocess waste water shall mean any 
water including precipitation runoff, which during manufacturing or 
processing, comes into incidental contact with any raw material, 
intermediate product, finished product, by-product or waste product by 
means of:
    (1) Precipitation runoff, (2) accidental spills, (3) accidental 
leaks caused by the failure of process equipment and which are repaired 
or the discharge of pollutants therefrom contained or terminated within 
the shortest reasonable time which shall not exceed 24 hours after 
discovery or when discovery should reasonably have been made, whichever 
is earliest, and (4) discharges from safety showers and related personal 
safety equipment, and from equipment washings for the purpose of safe 
entry, inspection and maintenance; provided that all reasonable measures 
have been taken to prevent, reduce, eliminate and control to the maximum 
extent feasible such contact and provided further that all reasonable 
measures have been taken that will mitigate the effects of such contact 
once it has occurred.
    (d) The term ten-year 24-hour rainfall event shall mean the maximum 
precipitation event with a probable recurrence interval of once in 10 
years as defined by the National Weather Service in technical paper no. 
40, ``Rainfall Frequency Atlas of the United States,'' May 1961, and 
subsequent amendments or equivalent regional or State rainfall 
probability information developed therefrom.
    (e) The term 25-year 24-hour rainfall event shall mean the maximum 
precipitation event with a probable recurrence interval of once in 25 
years as defined by the National Weather Service in technical paper no. 
40, ``Rainfall Frequency Atlas of the United States,'' May 1961, and 
subsequent amendments or equivalent regional or State rainfall 
probability information developed therefrom.



Sec.  422.52  Effluent limitations and guidelines representing the degree of effluent
reduction attainable by the application of the best practicable control 
          technology currently available.

    (a) Subject to the provisions of paragraphs (b), (c) and (d) of this 
section, the following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this section, which 
may be discharged by a point source subject to the provisions of this 
subpart after application of the best practicable control technology 
currently available: There shall be no discharge of process wastewater 
pollutants to navigable waters.
    (b) Process waste water pollutants from a cooling water 
recirculation system designed, constructed and operated to maintain a 
surge capacity equal to the runoff from the 10-year, 24-hour rainfall 
event may be discharged, after treatment to the standards set forth in 
paragraph (c) of this section, whenever chronic or catastrophic 
precipitation events cause the water level in the pond to rise into the 
surge capacity. Process waste water must be treated and discharged 
whenever the water level equals or exceeds the mid point of the surge 
capacity.
    (c) The concentration of pollutants discharged in process wastewater 
pursuant to the limitations of paragraph (b) of this section shall not 
exceed the values listed in the following table:

Sec.  423.10  Applicability.

    The provisions of this part apply to discharges resulting from the 
operation of a generating unit by an establishment whose generation of 
electricity is the predominant source of revenue or principal reason for 
operation, and whose generation of electricity results primarily from a 
process utilizing fossil-type fuel (coal, oil, or gas), fuel derived 
from fossil fuel (e.g., petroleum coke, synthesis gas), or nuclear fuel 
in conjunction with a thermal cycle employing the steam water system as 
the thermodynamic medium. This part applies to discharges associated 
with both the combustion turbine and steam turbine portions of a 
combined cycle generating unit.

Sec.  423.12  Effluent limitations guidelines representing the degree of effluent 
reduction attainable by the application of the best practicable control 
          technology currently available (BPT).

    (a) In establishing the limitations set forth in this section, EPA 
took into account all information it was able to collect, develop and 
solicit with respect to factors (such as age and size of plant, 
utilization of facilities, raw materials, manufacturing processes, non-
water quality environmental impacts, control and treatment technology 
available, energy requirements and costs) which can affect the industry 
subcategorization and effluent levels established. It is, however, 
possible that data which would affect these limitations have not been 
available and, as a result, these limitations should be adjusted for 
certain plants in this industry. An individual discharger or other 
interested person may submit evidence to the Regional Administrator (or 
to the State, if the State has the authority to issue NPDES permits) 
that factors relating to the equipment or facilities involved, the 
process applied, or other such factors related to such discharger are 
fundamentally different from the factors considered in the establishment 
of the guidelines. On the basis of such evidence or other

[[Page 650]]

available information, the Regional Administrator (or the State) will 
make a written finding that such factors are or are not fundamentally 
different for that facility compared to those specified in the 
Development Document. If such fundamentally different factors are found 
to exist, the Regional Administrator or the State shall establish for 
the discharger effluent limitations in the NPDES Permit either more or 
less stringent than the limitations established herein, to the extent 
dictated by such fundamentally different factors. Such limitations must 
be approved by the Administrator of the Environmental Protection Agency. 
The Administrator may approve or disapprove such limitations, specify 
other limitations, or initiate proceedings to revise these regulations. 
The phrase ``other such factors'' appearing above may include 
significant cost differentials. In no event may a discharger's impact on 
receiving water quality be considered as a factor under this paragraph.
    (b) Any existing point source subject to this subpart must achieve 
the following effluent limitations representing the degree of effluent 
reduction by the application of the best practicable control technology 
currently available (BPT):
    (1) The pH of all discharges, except once through cooling water, 
shall be within the range of 6.0-9.0.
    (2) There shall be no discharge of polychlorinated biphenyl 
compounds such as those commonly used for transformer fluid.
    (3) The quantity of pollutants discharged from low volume waste 
sources shall not exceed the quantity determined by multiplying the flow 
of low volume waste sources times the concentration lised in the 
following table:

    (f) Fly ash transport water. Except when the fly ash transport water 
is used in the FGD scrubber, for any electric generating unit with a 
total nameplate generating capacity of more than 50 megawatts and that 
is not an oil-fired unit, there shall be no discharge of pollutants in 
fly ash transport water. This standard applies to the discharge of fly 
ash transport water generated on and after November 1, 2018. Whenever 
fly ash transport water is used in any other plant process or is sent to 
a treatment system at the plant (except when it is used in the FGD 
scrubber), the resulting effluent must comply with the discharge 
standard in this paragraph. When the fly ash transport water is used in 
the FGD scrubber, the quantity of pollutants in fly ash transport water 
shall not exceed the quantity determined by multiplying the flow of fly 
ash transport water times the concentration listed in the table in 
paragraph (e) of this section.
    (g)(1) Except for those discharges to which paragraph (g)(2) 
applies, or when the bottom ash transport water is used in the FGD 
scrubber, for any electric generating unit with a total nameplate 
generating capacity of more than 50 megawatts, that is not an oil-fired 
unit, that is not a low utilization electric generating unit, and that 
the owner has not certified to the permitting authority that the 
electric generating unit will cease the cessation of coal combustion 
pursuant to Sec.  423.19(f), there shall be no discharge of pollutants 
in bottom ash transport water. This standard applies to the discharge of 
bottom ash transport water generated on and after October 13, 2023. 
Except for those discharges to which paragraph (g)(2) of this section 
applies, whenever bottom ash transport water is used in any other plant 
process or is sent to a treatment system at the plant (except when it is 
used in the FGD scrubber), the resulting effluent must comply with the 
discharge standard in this paragraph. When the bottom ash transport 
water is used in the FGD scrubber, the quantity of pollutants in bottom 
ash transport water shall not exceed the quantity determined by 
multiplying the flow of bottom ash transport water times the 
concentration listed in the table in paragraph (e) of this section.
    (2)(i) The discharge of pollutants in bottom ash transport water 
from a properly installed, operated, and maintained bottom ash system is 
authorized under the following conditions:
    (A) To maintain system water balance when precipitation-related 
inflows are generated from a 10-year storm event of 24-hour or longer 
duration (e.g., 30-day storm event) and cannot be managed by installed 
spares, redundancies, maintenance tanks, and

[[Page 665]]

other secondary bottom ash system equipment; or
    (B) To maintain system water balance when regular inflows from 
wastestreams other than bottom ash transport water exceed the ability of 
the bottom ash system to accept recycled water and segregating these 
other wastestreams is feasible; or
    (C) To maintain system water chemistry where current operations at 
the facility are unable to currently manage pH, corrosive substances, 
substances or conditions causing scaling, or fine particulates to below 
levels which impact system operation or maintenance; or
    (D) To conduct maintenance not otherwise included in paragraphs 
(g)(2)(i)(A)(1), (2), or (3) of this section and not exempted from the 
definition of transport water inSec.  423.11(p), and when water volumes 
cannot be managed by installed spares, redundancies, maintenance tanks, 
and other secondary bottom ash system equipment.
    (ii) The total volume that may be discharged to a POTW for the above 
activities shall be reduced or eliminated to the extent achievable as 
determined by the control authority. The control authority may also 
include control measures (including best management practices) that are 
technologically available and economically achievable in light of best 
industry practice. In no event shall the total volume of the discharge 
exceed a 30-day rolling average of ten percent of the primary active 
wetted bottom ash system volume. The volume of daily discharges used to 
calculate the 30-day rolling average shall be calculated using 
measurements from flow monitors.
    (iii) For bottom ash transport water generated by a low utilization 
electric generating unit, the quantity of pollutants discharged in 
bottom ash transport water shall incorporate the elements of a best 
management practices plan as described in Sec.  423.13(k)(3).
    (h) Flue gas mercury control wastewater. For any electric generating 
unit with a total nameplate generating capacity of more than 50 
megawatts and that is not an oil-fired unit, there shall be no discharge 
of pollutants in flue gas mercury control wastewater. This standard 
applies to the discharge of flue gas mercury control wastewater 
generated on and after November 1, 2018. Whenever flue gas mercury 
control wastewater is used in any other plant process or is sent to a 
treatment system at the plant, the resulting effluent must comply with 
the discharge standard in this paragraph.
    (i) Gasification wastewater. For any electric generating unit with a 
total nameplate generating capacity of more than 50 megawatts and that 
is not an oil-fired unit, the quantity of pollutants in gasification 
wastewater shall not exceed the quantity determined by multiplying the 
flow of gasification wastewater times the concentration listed in the 
table following this paragraph (i). Dischargers must meet the standards 
in this paragraph by November 1, 2018. These standards apply to the 
discharge of gasification wastewater generated on and after November 1, 
2018.

Sec.  424.20  Applicability; description of the covered electric furnaces and other
smelting operations with wet air pollution control devices subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the smelting of ferroalloys in covered electric furnaces 
or other smelting operations, not elsewhere included in this part, with 
wet air pollution control devices. This subcategory includes those 
electric furnaces of such construction or configuration (known as 
covered, closed, sealed, semi-covered or semi-closed furnaces) that the 
furnace off-gases are not burned prior to collection and cleaning, and 
which off-gases are cleaned after collection in a wet air pollution 
control device such as a scrubber, `wet' baghouse, etc. This subcategory 
also includes those non- electric furnace smelting operations, such as 
exothermic (i.e., aluminothermic or silicothermic) smelting, 
ferromanganese refining, etc., where these are controlled for air 
pollution by wet air pollution control devices. This subcategory does 
not include noncontact cooling water or those furnaces which utilize dry 
dust collection techniques, such as dry baghouses.



Sec.  424.21  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in part 401 of this chapter shall 
apply to this subpart.
    (b) The term Mwh shall mean megawatt hour(s) of electrical energy 
consumed in the smelting process (furnace power consumption).
