SUPPLEMENTARY INFORMATION:

I. Introduction

    The Regional Administrator of Region I is issuing final general 
permit for effluent discharges from water treatment facilities to 
certain waters of the States of Maine, Massachusetts, and New 
Hampshire. This notice contains two sets of appendices. Appendix A 
summarizes EPA's response to major comments received on the draft 
general permits published on July 28, 1994 (59 FR 38465). Appendix B 
contains the final general NPDES permits including Part II, Standard 
Conditions.

II. Coverage of General Permits

    Section 301(a) of the Clean Water Act (the Act) provides that the 
discharge of pollutants is unlawful except in accordance with a 
National Pollutant Discharge Elimination System (NPDES) permit. 
Although such permits to date have generally been issued to individual 
discharges, EPA's regulations authorize the issuance of ``general 
permits'' to categories of discharges. See 40 CFR 122.28 (48 FR 14146, 
April 1, 1983). EPA may issue a single, general permit to a category of 
point sources located within the same geographic area whose permits 
warrant similar pollutant control measures.
    The Director of an NPDES permit program is authorized to issue a 
general permit if there are a number of point sources operating in a 
geographic area that:
    1. Involve the same or substantially similar types of operations;
    2. Discharge the same types of wastes;
    3. Require the same effluent limitations or operating conditions;
    4. Require the same or similar monitoring requirements; and
    5. In the opinion of the Regional Administrator, are more 
appropriately controlled under a general permit than under individual 
permits.
    Violations of a condition of a general permit constitutes a 
violation of the Clean Water Act and subjects the discharger to the 
penalties in Section 309 of the Act.
    Any owner or operator authorized by a general permit may be 
excluded from coverage of a general permit by applying for an 
individual permit. This request may be made by submitting a NPDES 
permit application together with reasons supporting the request no 
later than 90 days after publication by EPA of the final general permit 
in the Federal Register. The Director may require any person authorized 
by a general permit to apply for and obtain an individual permit. Any 
interested person may petition the Director to take this action. 
However, individual permits will not be issued for sources discharging 
effluent from water treatment facility covered by this general permit 
unless it can be clearly demonstrated that inclusion under the general 
permit is inappropriate.
    The Director may consider the issuance of individual permits when:
    1. The discharge is a significant contributor of pollution;
    2. The discharge is not in compliance with the terms and conditions 
of the general permit;
    3. A change has occurred in the availability of demonstrated 
technology or practices for the control or abatement of pollutants 
applicable to the point source;
    4. Effluent limitations guidelines are subsequently promulgated for 
the point sources covered by the general permit;
    5. A Water Quality Management plan containing requirements 
applicable to such point sources is approved; or
    6. Circumstances have changed since the time of the request to be 
covered so that the discharger is no longer appropriately controlled 
under the general permit, or either a temporary or permanent reduction 
or elimination of the authorized discharge is necessary;
    In accordance with 40 CFR 122.28(b)(3)(iv), the applicability of 
the general permit is automatically terminated on the effective date of 
the individual permit.
    Under this general permit, owners and operators of potable water 
treatment plants in Massachusetts, Maine and New Hampshire may be 
granted authorization to discharge process generated wastewaters into 
waters of the respective States as follows:
    a. treated presedimentation underflow;
    b. treated underflow from the coagulation/settling processes using 
aluminum compounds or polymers as coagulants; and
    c. treated filter backwash water from filters.
    This permit shall apply specifically to operators that have a 
discharge from a point source such as a sludge settling lagoon or other 
device whereby comparable control of suspended solids is possible.
    Authorization under the permit shall require prior submittal of 
certain facility information. Upon receipt of all required information, 
the permit issuing authority may allow or disallow coverage under the 
general permit.
    The following list shows the criteria which will be used in 
evaluating whether or not an individual permit may be required instead 
of a general permit.
    1. Evidence on non-compliance under previous permit for the 
operation;
    2. Preservation of high quality waters and fisheries;
    3. Facilities with an effluent discharge flow of over 1.00 MGD 
maximum daily for the states of Massachusetts and New Hampshire and 
0.15 MGD maximum daily for the state of Maine;
    4. Production of effluent at the facility other than using aluminum 
compound or polymer as coagulant; and
    5. Use of land application as a means of discharge;
    6. For the state of Maine, a minimum dilution of effluent of 100:1 
in the receiving water at 7Q10 should be stipulated.
    The similarity of the discharges has prompted EPA to prepare this 
draft general permit for public review and comment. When issued, this 
permit will enable facilities to maintain compliance with the Act and 
will extend environmental and regulatory controls to a large number of 
discharges and reduce some permit backlog. The issuance of this general 
permit for the geographic areas described below is warranted by this 
similarity of (a) environmental conditions, (b) State regulatory 
requirements applicable to the discharges and receiving waters, and (c) 
technology employed.
    In the State of Maine, there are 271 industrial applicants or 
permittees. It is estimated that 13 of the industries that have direct 
discharges to the waters of the State are strictly water treatment 
facilities.
    In the State of New Hampshire, there are 171 estimated industrial 
applications or permittees. It is estimated that 2 or more of the 
industries that have the direct discharges to the waters of the State 
are strictly water treatment facilities.
    In the Commonwealth of Massachusetts, there are 651 industrial 
applicants or permittees. It is estimated that 33 of the industries 
that have direct discharges to the waters of the State are strictly 
water treatment facilities.

III. Conditions of the General NPDES Permit

A. Geographic Areas

    Maine (Permit No. MEG640000)--All of the discharges to be 
authorized by the general NPDES permit for the State of Maine from 
dischargers are limited to Class B,C,SB and SC waters of the State, 
except lakes. The drainage areas must be more than 10 square miles.
    Massachusetts (Permit No. MAG640000)--All of the discharges to be 
authorized by the general NPDES permit for the Commonwealth of 
Massachusetts dischargers are limited to Class B, ans SB waters as 
designated in Massachusetts Water Quality Standards, 314 CMR 4.00 et 
seq. Discharges into Class A water needs review and approval by MADEP.
    New Hampshire (Permit No. NHG640000)--All of the discharges to be 
authorized by the general NPDES permit for the State of New Hampshire 
dischargers are into all waters of the State of New Hampshire unless 
otherwise restricted by the State Water Quality Standards, New 
Hampshire RSA 485-A:8. (or as revised).

B. Notification by Permittees

    Operators of facilities whose discharge, or discharges, are 
described in Part II and whose facilities are located in the geographic 
areas described in Part III. A. above may submit to the Regional 
Administrator, Region I, a notice of intent to be covered by the 
appropriate general permit within 180 days of the effective date of the 
general permit. This written notification must include the owner's or 
operator's legal name and address; the facility name and address; the 
number and type of facilities to be covered, the facility locations; a 
topographic map (or other map if a topographic map is not available) 
indicating its facility locations; the names of the receiving waters 
into which discharge will occur; a determination as to whether or not 
the facility discharge will adversely affect a listed or proposed to be 
listed endangered or threatened species or its critical habitat (see 
Part E).
    The facilities authorized to discharge under a final general permit 
will receive written notification from EPA, Region I, with State 
concurrence. Failure to submit to EPA, Region I, a notice of intent to 
be covered or failure to receive from EPA written notification of 
permit coverage means that the facility is not authorized to discharge 
under this general permit.

C. Effluent Limitations

1. Statutory Requirements
    The Clean Water Act (the Act) prohibits the discharge of pollutants 
to waters of the United States without a National Pollutant Discharge 
Elimination System (NPDES) permit unless such a discharge is otherwise 
authorized by the Act. The NPDES Permit is the mechanism used to 
implement technology and water quality based effluent limitations and 
other requirements including monitoring and reporting. The NPDES permit 
was developed in accordance with various statutory and regulatory 
authorities established pursuant to the Act. The regulations governing 
the EPA NPDES Permit program are generally found at 40 CFR parts 122, 
124, 125 and 136.
    EPA is required to consider technology and water quality 
requirements when developing permit limits. 40 CFR part 125 Subpart A 
sets the criteria and standards that EPA must use to determine which 
technology based requirements, requirement under Section 301(b) of the 
Act and/or requirements established on a case-by-case basis under 
section 402(a)(1) of the Act, should be included in the permit.
    The Clean Water Act requires that all discharges, at a minimum, 
must meet effluent limitations based on the technological capability of 
dischargers to control pollutants in their discharge. Section 
301(b)(1)(A) of the Act requires the application of Best Practicable 
Control Technology Currently Available (BPT) with the statutory 
deadline for compliance being July 1, 1977, unless otherwise authorized 
by the Act. Section 301(b)(2) of the Act requires the application of 
Best Conventional Control Technology (BCT) for conventional pollutants, 
and Best Available Technology Economically Achievable (BAT) for non-
conventional and toxic pollutants. The compliance deadline for BCT and 
BAT being March 31, 1980.
2. Technology-Based Effluent Limitations
    EPA has not promulgated National Effluent Guidelines for water 
treatment facilities. For a category where Guidelines have been 
promulgated, the issuance of an individual permit for the discharges 
would be more appropriate (See 40 CFR 122.28(b)(3)(i)(C)). Therefore, 
as provided in section 402(a)(1) of the Act, EPA has determined to 
issue this general permit utilizing Best Professional Judgement (BPT) 
to meet the above stated criteria for BAT/BCT described in section 
304(b) of the Act. Accordingly monthly average TSS limitation is 
established based upon best professional judgement pursuant to Section 
402(a)(1) of the CWA.
Water Quality Based Effluent Limitations
    Under Section 301(b)(1)(C) of the Act discharges are subject to 
effluent limitations based on water quality standards and to the 
conditions of State certification under section 401 of the Act. 
Receiving stream requirements are established according to numerical 
and narrative standards adopted under state and/or federal law for each 
stream use classification. The CWA requires that EPA obtain State 
certification which states that all water quality standards will be 
satisfied. Regulations governing State certification are set forth in 
40 CFR Sec. 124.53 and 124.55.
    Section 101(a)(3) of the Act specifically prohibits the discharge 
of toxic pollutants in toxic amounts. The States of Maine, 
Massachusetts, and New Hampshire have similar narrative criteria in 
their water quality regulations (See Maine Title 38, Article 4-A, 
section 420 and section 464.4.A.(4); Massachusetts 314 CMR 4.05(5)(e); 
and New Hampshire Part Env-Ws 432.02(c)(4) that prohibits such 
discharges. The permit does not allow for the addition of materials or 
chemicals in amounts which would produce a toxic effect to any aquatic 
life.
    The effluent from the water treatment facility may contain toxic 
pollutants due to use of chemicals and chlorine. However, they do not 
contain hazardous pollutants or oil and grease. Therefore, water 
quality criteria established for oil and grease and hazardous 
pollutants do not apply to these discharges. Water Quality Standards 
and State certification requirements applicable to these discharges 
have been reviewed by EPA and the limits and testing requirements for 
each State are given below:
    Massachusetts: Limits of Max. Daily TSS, Monthly Average and Max 
Daily Settleable Solids and pH. Testing requirements for Chlorine, 
Aluminum, LC50 and C-NOEC.
    Maine: Limits of Chlorine Aluminum and pH. Testing requirements of 
LC50 and C-NOEC.
    New Hampshire: Limit of pH. Testing requirements of Chlorine, 
Aluminum, LC50 and C-NOEC.

D. Antidegradation Provisions

    The conditions of the permit reflect the goal of the CWA and EPA to 
achieve and maintain water quality standards. The environmental 
regulations pertaining to the State Antidegradation Policies which 
protect the State's surface waters from falling below State standards 
for water quality are found in the following provisions: Maine Title 
38, Article 4-A, Section 464.4.F.; Massachusetts Water Quality 
Standards 314 CMR 4.04 Antidegradation Provisions; and New Hampshire 
policy RSA 485-A;8, VI Part Env-Ws 437.01 and Env-Ws 437.02.
    This general permit will not apply to any new or increased 
discharge unless it can be determined that such discharges will result 
in insignificant effects to the receiving waters. This determination 
shall be made in accordance with the appropriate State Antidegradation 
Policies.

E. Monitoring and Reporting Requirements

    Effluent limitations and monitoring requirements are included in 
the general permit describing requirements to be imposed on facilities 
to be covered.
    Facilities covered by the final general permits will be required to 
submit to EPA, Region I, and the appropriate State a Discharge 
Monitoring Report containing effluent data on a semi-annual basis.
    The monitoring requirements have been established to yield data 
representative of the discharge under authority of Section 308(a) of 
the Act and 40 CFR 122.41(j), 122.44(i) and 122.48, and as certified by 
the State.

F. Endangered Species

    Discharges that may adversely affect a listed or proposed to be 
listed endangered or threatened species or its critical habitat are not 
authorized under this general permit without the written approval of 
the Fish and Wildlife Service and/or the National Marine Fisheries 
Service.
    The Fish and Wildlife Service has indicated that the dwarf wedge 
mussel (Alsmidonta heterodon), a Federally listed endangered species, 
occurs in a stretch of the Connecticut River from Lebanon, New 
Hampshire to Weathersfield Bow, Vermont, in the Ashuelot River in 
Keene, New Hampshire and historically from a number of rivers in 
Massachusetts, Any facility whose discharge may adversely effect the 
mussel or any other threatened or endangered species or its habitat is 
required to contact the Fish and Wildlife Service at the following 
address in order to make a formal determination: United States 
Department of the Interior, Fish and Wildlife Service, 400 Ralph Pill 
Marketplace, 22 Bridge Street, Concord, New Hampshire 03301-4901.
    The National Marine Fisheries Service has indicated that the 
endangered shortnose sturgeon (Acipenser breviirostrum) inhabits 
certain sections of the Penobscot, Kennebec and Androscoggin Rivers in 
Maine, and the Merrimack and Connecticut Rivers in Massachusetts. Any 
facility whose discharge may adversely effect the sturgeon or any other 
threatened or endangered species or its habitat is required to contact 
the national Marine Fisheries Service at the following address: United 
States Department of Commerce, National Oceanic and Atmospheric 
Administration, National Marine Fisheries Service, Habitat and 
Protected Resources Division, One Blackburn Drive, Gloucester, 
Massachusetts 01903-2298.

G. Other Requirements

    The remaining conditions of the permit are based on the NPDES 
regulations 40 CFR Parts 122 through 125 and consist primarily of 
management requirements common to all permits.

IV. State Certification

    Section 401 of the CWA provides that no Federal license or permit, 
including NPDES permits, to conduct any activity that may result in any 
discharge into navigable waters shall be granted until the State in 
which the discharge originates certifies that the discharge will comply 
with the applicable provisions of sections 301, 302, 303, 306, and 307 
of the CWA. The section 401 certification process has been completed 
for all States covered by today's general permit.

V. Administrative Aspects

A. Request To Be Covered

    A facility is not covered by any of these general permits until it 
meets the following requirements. First, it must send a notice of 
intent to EPA and the appropriate State indicating it meets the 
requirements of the permit and wants to be covered. And second, it must 
be notified in writing by EPA that it is covered by this general 
permit.
    Any facility operating under any effective individual NPDES permit 
may request that the individual permit be revoked and that coverage 
under the general permit granted, as outlined in 40 CFR 
122.28(b)(3)(v). If EPA grants coverage under the general permit, EPA 
will so notify the facility and revoke the individual permit.
    Facilities with expire individual permits that have been 
administratively continued in accordance with Sec. 122.6 may apply for 
coverage under this general permit. When coverage is granted the 
expired individual permit automatically will cease being in effect.

B. The Coastal Zone Management Act

    The Coastal Zone Management Act (CZMA), 16 U.S.C. Secs. 1451 et 
seq., and its implementing regulations [15 CFR Part 930] require that 
any federally licensed activity affecting the coastal zone with an 
approved Coastal Zone Management Program (CZMP) be determined to be 
consistent with the CZMP. EPA, Region I, has determined that these 
general NPDES permits are consistent with the CZMP. EPA has received 
certification from the Massachusetts, Maine, and New Hampshire coastal 
zone agencies for a determination that these three permits are 
consistent with their respective State policies.

C. The Endangered Species Act

    EPA Region I has concluded that the discharges to be covered by the 
general NPDES permits will not affect or jeopardize the continued 
existence of any endangered or threatened species or adversely affect 
its critical habitat. The U.S. Fish and Wildlife Service and the 
National Marine Fisheries Service concur this conclusion.

D. Environmental Impact Statement Requirements

    The general permits do not authorize the construction of any water 
resources project or the impoundment of any water body or have any 
effect on historical property, and are not major Federal activities 
needing preparation of any Environmental Impact Statement. Therefore, 
the Wild and Scenic Rivers Act, 16 U.S.C. Secs. 1273 et seq., the 
National Historic Preservation Act of 1966, 16 U.S.C Secs. 470 et seq., 
the Fish and Wildlife Coordination Act, 16 U.S.C. Secs. 661 et seq., 
and the National Environmental Policy Act, 33 U.S.C. Secs. 4321 et 
seq., do not apply to the issuance of this general NPDES permit.

VI. Other Legal Requirements

A. Economic Impact (Executive Order 12291)

    EPA has reviewed the effect of Executive Order 12291 on this draft 
general permit and has determined that it is not a major rule under 
that order. This regulation was submitted previously to the Office of 
Management and Budget for review as required by Executive Order 12291. 
The Office of Management and Budget has exempted this action from the 
review requirements of Executive Order 12291 pursuant to Section 8(b) 
of that Order.

B. Paperwork Reduction Act

    EPA has reviewed the requirements imposed on regulated facilities 
by these draft general NPDES permits under the Paperwork Reduction Act 
of 1980, 44 U.S.C. Secs. 3501 et. seq. The information collection 
requirements of these draft permits have already been approved by the 
Office of Management and Budget under submissions made for the NPDES 
permit program under the provisions of the Clean Water Act. No comments 
from the Office of Management and Budget or the public were received on 
the information collection requirements in these permits.

C. The Regulatory Flexibility Act

    After review of the facts presented in the notice printed above, I 
hereby certify, pursuant to the provisions of 5 U.S.C. Sec. 605(b), 
that this permit does not have a significant impact on a substantial 
number of small entities. Moreover, the draft permit will reduce a 
significant administrative burden on regulated sources.

    Dated: November 20, 1994.
John P. DeVillars,
Regional Administrator.

Appendix A--Summary of Responses to Public Comments on the July 28, 
1994 Draft General Permit

    Based on comments from the States of Maine and New Hampshire the 
requirement of Footnote No. 1 under Part I 1.a. is limited for the 
State of Massachusetts only. Based on another comment the note A.1.h. 
under Part I A.l.h. has been changed. The change is that the Toxicity 
testing will be performed when requested by EPA or State within 90 days 
after the date of request.

Appendix B--Final General Permit Under the National Pollutant Discharge 
Elimination System (NPDES)

    Note: The Following general NPDES permit has been combined for 
purposes of this Federal Register notice in order to eliminate 
duplication of material common to all permits for the individual 
states.

1. Massachusetts, Maine and New Hampshire General Permit

    In compliance with the provisions of the Federal Clean Water Act, 
as amended, (33 U.S.C. 1251 et.seq. the ``CWA'') operators of 
facilities located in Part III A. which discharge effluent from water 
treatment facilities as defined in Part II of Supplementary Information 
to waters as designated in Part III A in accordance with effluent 
limitations, monitoring requirements and other conditions set forth 
herein.
    This permit shall become effective when issued.
    This permit and the authorization to discharge expire at midnight, 
five years from the effective date of the Federal Register Publication.
    This permit consists of Part I below including effluent 
limitations, monitoring requirements etc. and Part II General 
Requirements.
    Operators of facilities within the general permit area who fail to 
notify the Director of their intent to be covered by this general 
permit and receive no written notification of permit coverage or those 
who are denied by the Director are not authorized under this general 
permit to discharge from those facilities to the receiving waters.

Part II, Standard Conditions

Section A. General Requirements

1. Duty To Comply
    The permittee must comply with all conditions of this permit. Any 
permit noncompliance constitutes a violation of the Clean Water Act and 
is grounds for enforcement action; for permit termination, revocation 
and reissuance, or modification; or for denial of a permit renewal 
application.
    a. The permittee shall comply with effluent standards or 
prohibitions established under Section 307(a) of the CWA for toxic 
pollutants and with standards for sewage sludge use or disposal 
established under Section 405(d) of the CWA within the time provided in 
the regulations that establish these standards or prohibitions, even if 
the permit has not yet been modified to incorporate the requirement.
    b. The CWA provides that any person who violates Sections 301, 302, 
306, 307, 308, 318, or 405 of the CWA or any permit condition or 
limitation implementing any of such sections in a permit issued under 
Section 402, or any requirement imposed in a pretreatment program 
approved under Sections 402(a)(3) or 402(b)(8) of the CWA is subject to 
a civil penalty not to exceed $25,000 per day for each violation. Any 
person who negligently violates such requirements is subject to a fine 
of not less than $2,500 nor more than $25,000 per day of violation, or 
by imprisonment for not more than 1 year, or both. Any person who 
knowingly violates such requirements is subject to a fine of not less 
than $5,000 nor more than $50,000 per day of violation, or by 
imprisonment for not more than 3 years, or both. Note: See 40 CFR 
122.41(a)(2) for additional enforcement criteria.
    c. Any person may be assessed an administrative penalty by the 
Administrator for violating Section 301, 302, 306, 307, 308, 318, or 
405 of the CWA, or any permit condition or limitation implementing any 
of such sections in a permit issued under Section 402 of the CWA. 
Administrative penalties for Class I violations are not to exceed 
$10,000 per violation, with the maximum amount of any Class I penalty 
assessed not to exceed $25,000. Penalties for Class II violations are 
not to exceed $10,000 per day for each day during which the violation 
continues, with the maximum amount of any Class II penalty not to 
exceed $125,000.
2. Permit Actions
    This permit may be modified, revoked and reissued, or terminated 
for cause. The filing of a request by the permittee for a permit 
modification, revocation and reissuance, or termination, or a 
notification of planned changes or anticipated noncompliance does not 
stay any permit condition.
3. Duty To Provide Information
    The permittee shall furnish to the Regional Administrator, within a 
reasonable time, any information which the Regional Administrator may 
request to determine whether cause exists for modifying, revoking and 
reissuing, or terminating this permit, or to determine compliance with 
this permit. The permittee shall also furnish to the Regional 
Administrator, upon request, copies of records required to be kept by 
this permit.
4. Reopener Clause
    The Regional Administrator reserves the right to make appropriate 
revisions to this permit in order to establish any appropriate effluent 
limitations, schedules of compliance, or other provisions which may be 
authorized under the CWA in order to bring all discharges into 
compliance with the CWA.
5. Oil and Hazardous Substance Liability
    Nothing in this permit shall be construed to preclude the 
institution of any legal action or relieve the permittee from any 
responsibilities, liabilities, or penalties to which the permittee is 
or may be subject under Section 311 of the CWA, or Section 106 of the 
Comprehensive Environmental Response, Compensation and Liability Act of 
1980 (CERCLA).
6. Property Rights
    The issuance of this permit does not convey any property rights of 
any sort, nor any exclusive privileges.
7. Confidentiality of Information
    a. In accordance with 40 CFR Part 2, any information submitted to 
EPA pursuant to these regulations may be claimed as confidential by the 
submitter. Any such claim must be asserted at the time of submission in 
the manner prescribed on the application form or instructions or, in 
the case of other submissions, by stamping the words ``confidential 
business information'' on each page containing such information. If no 
claim is made at the time of submission, EPA may make the information 
available to the public without further notice. If a claim is asserted, 
the information will be treated in accordance with the procedures in 40 
CFR Part 2 (Public Information).
    b. Claims of confidentiality for the following information will be 
denied:
    (i) The name and address of any permit applicant or permittee;
    (ii) Permit applications, permits, and effluent data as defined in 
40 CFR 2.302(a)(2).
    c. Information required by NPDES application forms provided by the 
Regional Administrator under Sec. 122.21 may not be claimed 
confidential. This includes information submitted on the forms 
themselves and any attachments used to supply information required by 
the forms.
8. Duty To Reapply
    If the permittee wishes to continue an activity regulated by this 
permit after its expiration date, the permittee must apply for and 
obtain a new permit. The permittee shall submit a new application at 
least 180 days before the expiration date of the existing permit, 
unless permission for a later date has been granted by the Regional 
Administrator. (The Regional Administrator shall not grant permission 
for applications to be submitted later than the expiration date of the 
existing permit.)
9. State Authorities
    Nothing in Part 122, 123, or 124 precludes more stringent State 
regulation of any activity covered by these regulations, whether or not 
under an approved State program.
10. Other Laws
    The issuance of a permit does not authorize any injury to persons 
or property or invasion of other private rights, nor does it relieve 
the permittee of its obligation to comply with any other applicable 
Federal, State, and local laws and regulations.

Section B. Operation and Maintenance of Pollution Controls

1. Proper Operation and Maintenance
    The permittee shall at all times properly operate and maintain all 
facilities and systems of treatment and control (and related 
appurtenances) which are installed or used by the permittee to achieve 
compliance with the conditions of this permit and with the requirements 
of storm water pollution prevention plans. Proper operation and 
maintenance also includes adequate laboratory controls and appropriate 
quality assurance procedures. This provision requires the operation of 
back-up or auxiliary facilities or similar systems only when the 
operation is necessary to achieve compliance with the conditions of the 
permit.
2. Need to Halt or Reduce Not a Defense
    It shall not be a defense for a permittee in an enforcement action 
that it would have been necessary to halt or reduce the permitted 
activity in order to maintain compliance with the conditions of this 
permit.
3. Duty to Mitigate
    The permittee shall take all reasonable steps to minimize or 
prevent any discharge or sludge use or disposal in violation of this 
permit which has a reasonable likelihood of adversely affecting human 
health or the environment.
4. Bypass
    a. Definitions.
    (1) ``Bypass'' means the intentional diversion of waste streams 
from any portion of a 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 exceeding limitations. The permittee may allow any 
bypass to occur which does not cause effluent limitations to be 
exceeded, but only if it also is for essential maintenance to assure 
efficient operation. These bypasses are not subject to the provisions 
of Paragraphs B.4.c and 4.d of this section.
    c. Notice.
    (1) Anticipated bypass.
    If the permittee knows in advance of the need for a bypass, it 
shall submit prior notice, if possible at least ten days before the 
date of the bypass.
    (2) Unanticipated bypass.
    The permittee shall submit notice of an unanticipated bypass as 
required in Paragraph D.1.e (24-hour notice).
    d. Prohibition of bypass.
    (1) Bypass is prohibited, and the Regional Administrator may take 
enforcement action against a permittee for bypass, unless:
    (a) Bypass was unavoidable to prevent loss of life, personal 
injury, or severe property damage;
    (b) There were no feasible alternatives to the bypass, such as the 
use of auxiliary treatment facilities, retention of untreated wastes, 
or maintenance during normal periods of equipment downtime. This 
condition is not satisfied if adequate back-up equipment should have 
been installed in the exercise of reasonable engineering judgment to 
prevent a bypass which occurred during normal periods of equipment 
downtime or preventive maintenance; and
    (c) (i) The permittee submitted notices as required under Paragraph 
4.c of this section.
    (ii) The Regional Administrator may approve an anticipated bypass, 
after considering its adverse effects, if the Regional Administrator 
determines that it will meet the three conditions listed above in 
Paragraph 4.d of this section.
5. Upset
    a. Definition. ``Upset'' means an exceptional incident in which 
there is unintentional and temporary non-compliance with technology-
based permit effluent limitations because of factors beyond the 
reasonable control of the permittee. An upset does not include 
noncompliance to the extent caused by operational error, improperly 
designed treatment facilities, inadequate treatment facilities, lack of 
preventive maintenance, or careless or improper operation.
    b. Effect of an upset. An upset constitutes an affirmative defense 
to an action brought for noncompliance with such technology-based 
permit effluent limitations if the requirements of Paragraph B.5.c of 
this section are met. No determination made during administrative 
review of claims that noncompliance was caused by upset, and before an 
action for noncompliance, is final administrative action subject to 
judicial review.
    c. Conditions necessary for a demonstration of upset. A permittee 
who wishes to establish the affirmative defense of upset shall 
demonstrate, through properly signed, contemporaneous operating logs, 
or other relevant evidence that:
    (1) An upset occurred and that the permittee can identify the 
cause(s) of the upset;
    (2) The permitted facility was at the time being properly operated;
    (3) The permittee submitted notice of the upset as required in 
Paragraphs D.1.a and 1.e (24-hour notice); and
    (4) The permittee complied with any remedial measures required 
under B.3. above.
    d. Burden of proof. In any enforcement proceeding the permittee 
seeking to establish the occurrence of an upset has the burden of 
proof.

Section C. Monitoring and Records

1. Monitoring and Records
    a. Samples and measurements taken for the purpose of monitoring 
shall be representative of the monitored activity.
    b. Except for records of monitoring information required by this 
permit related to the permittee's sewage sludge use and disposal 
activities, which shall be retained for a period of at least five years 
(or longer as required by 40 CFR Part 503), the permittee shall retain 
records of all monitoring information, including all calibration and 
maintenance records and all original strip chart recordings for 
continuous monitoring instrumentation, copies of all reports required 
by this permit, and records of all data used to complete the 
application for this permit, for a period of at least 3 years from the 
date of the sample, measurement, report or application except for the 
information concerning storm water discharges which must be retained 
for a total of 6 years. This retention period may be extended by 
request of the Regional Administrator at any time.
    c. Records of monitoring information shall include:
    (1) The date, exact place, and time of sampling or measurements;
    (2) The individual(s) who performed the sampling or measurements;
    (3) The date(s) analyses were performed;
    (4) The individual(s) who performed the analyses;
    (5) The analytical techniques or methods used; and
    (6) The results of such analyses.
    d. Monitoring results must be conducted according to test 
procedures approved under 40 CFR Part 136 or, in the case of sludge use 
or disposal, approved under 40 CFR Part 136 unless otherwise specified 
in 40 CFR Part 503, unless other test procedures have been specified in 
the permit.
    e. The Clean Water Act provides that any person who falsifies, 
tampers with, or knowingly renders inaccurate any monitoring device or 
method required to be maintained under this permit shall, upon 
conviction, be punished by a fine of not more than $10,000, or by 
imprisonment for not more than 2 years, or both. If a conviction of a 
person is for a violation committed after a first conviction of such 
person under this paragraph, punishment is a fine of not more than 
$20,000 per day of violation, or by imprisonment of not more than 4 
years, or both.
2. Inspection and Entry
    The permittee shall allow the Regional Administrator, or an 
authorized representative (including an authorized contractor acting as 
a representative of the Administrator), upon presentation of 
credentials and other documents as may be required by law, to:
    a. Enter upon the permittee's premises where a regulated facility 
or activity is located or conducted, or where records must be kept 
under the conditions of this permit;
    b. Have access to and copy, at reasonable times, any records that 
must be kept under the conditions of this permit;
    c. Inspect at reasonable times any facilities, equipment (including 
monitoring and control equipment), practices, or operations regulated 
or required under this permit; and
    d. Sample or monitor at reasonable times, for the purposes of 
assuring permit compliance or as otherwise authorized by the Clean 
Water Act, any substances or parameters at any location.

Section D. Reporting Requirements

1. Reporting Requirements
    a. Planned changes. The permittee shall give notice to the Regional 
Administrator as soon as possible of any planned physical alterations 
or additions to the permitted facility. Notice is required only when:
    (1) The alteration or addition to a permitted facility may meet one 
of the criteria for determining whether a facility is a new source in 
40 CFR Sec. 122.29(b); or
    (2) The alteration or addition could significantly change the 
nature or increase the quantity of pollutants discharged. This 
notification applies to pollutants which are subject to the effluent 
limitations in the permit, nor to the notification requirements under 
40 CFR Sec. 122.42(a)(1).
    (3) The alteration or addition results in a significant change in 
the permittee's sludge use or disposal practices, and such alteration, 
addition or change may justify the application of permit conditions 
different from or absent in the existing permit, including notification 
of additional use or disposal sites not reported during the permit 
application process or not reported pursuant to an approved land 
application plan.
    b. Anticipated noncompliance. The permittee shall give advance 
notice to the Regional Administrator of any planned changes in the 
permitted facility or activity which may result in noncompliance with 
permit requirements.
    c. Transfers. This permit is not transferable to any person except 
after notice to the Regional Administrator. The Regional Administrator 
may require modification or revocation and reissuance of the permit to 
change the name of the permittee and incorporate such other 
requirements as may be necessary under the Clean Water Act. (See 
Sec. 122.61; in some cases, modification or revocation and reissuance 
is mandatory.)
    d. Monitoring reports. Monitoring results shall be reported at the 
intervals specified elsewhere in this permit.
    (1) Monitoring results must be reported on a Discharge Monitoring 
Report (DMR) or forms provided or specified by the Regional 
Administrator for reporting results of monitoring of sludge use or 
disposal practices.
    (2) If the permittee monitors any pollutant more frequently than 
required by the permit using test procedures approved under 40 CFR Part 
136 or, in the case of sludge use or disposal, approved under 40 CFR 
Part 136 unless otherwise specified in 40 CFR Part 503, or as specified 
in the permit, the results of this monitoring shall be included in the 
calculation and reporting of the data submitted in the DMR or sludge 
reporting form specified by the Regional Administrator.
    (3) Calculations for all limitations which require averaging of 
measurements shall utilize an arithmetic mean unless otherwise 
specified by the Regional Administrator in the permit.
    e. Twenty-four hour reporting.
    (1) The permittee shall report any noncompliance which may endanger 
health or the environment. Any information shall be provided orally 
within 24 hours from the time the permittee becomes aware of the 
circumstances.
    A written submission shall also be provided within 5 days of the 
time the permittee becomes aware of the circumstances. The written 
submission shall contain a description of the noncompliance and its 
cause; the period of noncompliance, including exact dates and times, 
and if the noncompliance has not been corrected, the anticipated time 
it is expected to continue; and steps taken or planned to reduce, 
eliminate, and prevent reoccurrence of the noncompliance.
    (2) The following shall be included as information which must be 
reported within 24 hours under this paragraph.
    (a) Any unanticipated bypass which exceeds any effluent limitation 
in the permit. (See Sec. 122.41(g))
    (b) Any upset which exceeds any effluent limitation in the permit.
    (c) Violation of a maximum daily discharge limitation for any of 
the pollutants listed by the Regional Administrator in the permit to be
