Discharges in the States of Maine, Massachusetts, and New Hampshire

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Final NPDES General Permits--MEG250000, MAG250000, 
and NHG250000.

-----------------------------------------------------------------------

SUMMARY: The Director of the Office of Ecosystem Protection, EPA-New 
England, is issuing Notice of Final National Pollutant Discharge 
Elimination System (NPDES) general permits for non-contact cooling 
water discharges to certain waters of the States of Maine, 
Massachusetts, and New Hampshire for the purpose of reissuing the 
current permit which expired on May 31, 1999. These general NPDES 
permits establish notice of intent (NOI) requirements, effluent 
limitations, standards, prohibitions and management practices for the 
non-contact cooling water discharges. Owners and/or operators of 
facilities discharging non-contact cooling water including those 
currently authorized to discharge under the expired general permit will 
be required to submit to EPA-New England, a notice of intent to be 
covered by the appropriate general permit and will receive a written 
notification from EPA of permit coverage and authorization to discharge 
under one of the general permits. The eligibility requirements are 
discussed in detail under part I. D.3.b and the reader is strongly 
urged to go to that section before reading further. This general permit 
does not cover new sources as defined under 40 CFR 122.2.

DATES: The general permit shall be effective on the date specified in 
the final general permit published in the Federal Register and will 
expire April 25, 2005.

ADDRESSES: Notices of intent to be authorized to discharge under these 
permits should be sent to: Environmental Protection Agency, 1 Congress 
Street, Suite 1100 (CMU), Boston, Massachusetts 02114-2023.
    The submittal of other information required under these permits or 
individual permit applications should also be sent to the above 
address.

FOR FURTHER INFORMATION CONTACT: Additional information concerning the 
final permit may be obtained between the hours of 9:00 a.m. and 5:00 
p.m. Monday through Friday excluding holidays from: Suprokash Sarker,

Fact Sheet and Supplemental Information

I. Introduction

    The Director of the Office of Ecosystem Protection, EPA-New 
England, is issuing final general permits for non-contact cooling water 
discharges to certain waters of the States of Maine, Massachusetts, and 
New Hampshire. This document contains part I for the final general 
NPDES permits and 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 unless 
such a discharge is otherwise authorized by the Act. 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 ). EPA may issue a single, 
general permit to a category of point sources located within the same 
geographic area whose discharges warrant similar pollution control 
measures.
    A. 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 Director, are more appropriately 
controlled under a general permit than under individual permits.
    B. The similarity of the discharges prompted EPA to issue the April 
28, 1994 general permit. When reissued, this permit will enable 
facilities currently covered under the expired general permit to 
maintain compliance with the Act and will extend environmental and 
regulatory controls to new dischargers and avoid a backlog of 
individual permit applications. Violations of a condition of a general 
permit constitute a violation of the Clean Water Act and subjects the 
discharger to the penalties in section 309 of the Act.

III. Exclusions

    This general permit is not available to facilities which have 
cooling water intake structures that do not reflect the best technology 
available for minimizing adverse environmental impact, as required by 
section 316(b) of the Clean Water Act. This general permit is also not 
available to those facilities seeking alternative thermal limitations 
pursuant to section 316(a) of the Clean Water Act.
    EPA has also determined that this general permit will not be 
available to ``New Source'' dischargers as defined in 40 CFR 122.2 due 
to the site specific nature of the environmental review required by the 
National Environmental Policy Act of 1969 (NEPA), 33 U.S.C. 4321 et 
seq. for those facilities. ``New Sources'' must comply with New Source 
Performance Standards (NSPS) and are subject to the NEPA process in 40 
CFR 6.600. Consequently EPA has determined that it would be more 
appropriate to address ``New Sources'' through the individual permit 
process.
    Any owner or operator authorized by a general permit may request to 
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. The 
Director may also 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 non-contact cooling water 
covered by these general permits unless it can be clearly demonstrated 
that inclusion under the general permit is inappropriate. The Director 
may consider the issuance of individual permits when:
    A. The discharger is not in compliance with the terms and 
conditions of the general permit;
    B. A change has occurred in the availability of demonstrated 
technology or practices for the control or abatement of pollutants 
applicable to the point source;
    C. Effluent limitations guidelines are subsequently promulgated for 
the point sources covered by the general NPDES permit;
    D. A Water Quality Management plan or Total Maximum Daily Load 
(TMDL) containing requirements applicable to such point sources is 
approved;
    E. Circumstances have changed since the time of the request to be 
covered so that the discharger is no longer appropriately controlled 
under the general permit, or either a temporary or permanent reduction 
or elimination of the authorized discharge is necessary; or
    F. The discharge(s) is a significant contributor of pollution.
    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.

IV. Permit Basis and Other Conditions of the General NPDES Permit

A. Effluent Limitations

1. Statutory Requirements
    Section 301(a) of the Clean Water Act (CWA or the Act), 33 U.S.C. 
1311(a), makes it unlawful to discharge pollutants to waters of the 
United States without a permit. Section 402 of the Act, 33 U.S.C. 1342, 
authorizes EPA to issue NPDES permits allowing discharges that will 
meet certain

[[Page 24197]]

requirements, including CWA sections 301, 304, and 401 (33 U.S.C. 1331, 
1314, and 1341). Those statutory provisions state that NPDES permits 
must include effluent limitations requiring authorized discharges to: 
(1) Meet standards reflecting specified levels of technology-based 
treatment requirements; (2) comply with State Water Quality Standards; 
and (3) comply with other state requirements adopted under authority 
retained by states under CWA section 510, 33 U.S.C. 1370.
    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, requirements 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 technology-based treatment 
requirements for 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 is as expeditiously as practicable 
but in no case later than three years after the date such limitations 
are promulgated and in no case later than March 31, 1989.
2. Technology-based Effluent Limitations
    EPA has not promulgated National Effluent Guidelines for non-
contact cooling water discharges. EPA believes that the limits 
established to meet the Water Quality Standards discussed below are 
sufficient to satisfy BAT/BCT described in section 304(b) of the Act.
3. 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. Receiving stream 
requirements are established according to numerical and narrative 
standards adopted under state and/or federal law for each stream use 
classification. Section 401 of the CWA requires that EPA obtain State 
certification which ensures that all water quality standards and other 
appropriate requirements of state law will be satisfied. Regulations 
governing State certification are set forth in 40 CFR 124.53 and 
124.55.
    The States of Maine, Massachusetts, and New Hampshire have 
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 430.50(a) that prohibits 
toxic discharges in toxic amounts. The permit does not allow for the 
addition of materials or chemicals in amounts which would produce a 
toxic effect to any aquatic life.
    Non-contact cooling water discharges do not contain or come in 
contact with raw materials, intermediate products, finished products, 
or process wastes. Therefore, it could be assumed that the discharges 
do not contain toxic or hazardous pollutants or oil and grease. 
Nevertheless, toxic effects may still occur as a result of toxic source 
water or due to dissolution of the piping in the cooling water systems. 
Any non-contact cooling water discharges which would violate water 
quality criteria established for toxic or hazardous pollutants would 
not qualify for this general permit and an individual permit would be 
required.
    Water quality standards applicable to non-contact cooling water 
discharges covered by this general permit include pH and temperature. 
The limitations for pH and temperature are based upon limitations in 
the existing permit in accordance with the antibacksliding requirements 
found in 40 CFR 122.44(1). The permittees have been able to achieve 
consistent compliance with all these limitations. The state of New 
Hampshire may consider a change in pH under certain conditions. The 
following language reveals when pH can be changed for the state of New 
Hampshire:
    The pH limits in the draft permit remain unchanged from the 
existing permit, however, language has been added to this draft permit 
allowing for a change in pH limit(s) under certain conditions as per 
State Permit Conditions (part I.C.2.a.). A change would be considered 
if the applicant can demonstrate to the satisfaction of NHDES-WD that 
the in-stream pH standard will be protected when the discharge is 
outside the permitted range, then the applicant or NHDES-WD may request 
(in writing) that the permit limits be modified by EPA to incorporate 
the results of the demonstration.
    Anticipating the situation where NHDES-WD grants a formal approval 
changing the pH limit(s) to outside the 6.5 to 8.0 Standard Units 
(S.U.), EPA has added a provision to this draft permit (see New 
Hampshire part I.C.1.g.). That provision will allow EPA to modify the 
pH limit(s) using a certified letter approach. This change will be 
allowed as long as it can be demonstrated that the revised pH limit 
range does not alter the naturally occurring receiving water pH. 
Reference part I.C.2.a. State Permit Conditions in that permit. 
However, the pH limit range cannot be less restrictive than found in 
the applicable National Effluent Limitation Guideline for the facility 
or to a default range of 6.0 to 9.0 S.U. in the situation of no 
applicable guideline, whichever is more stringent.
    If the State approves results from a pH demonstration study, this 
permit's pH limit range can be relaxed in accordance with 40 CFR 
122.44(l)(2)(i)(B) because it will be based on new information not 
available at the time of this permit's issuance. This new information 
includes results from the pH demonstration study that justifies the 
application of a less stringent effluent limitation. EPA anticipates 
that the limit determined from the demonstration study as approved by 
the NHDES-WD will satisfy all effluent requirements for this discharge 
category and will comply with New Hampshire's Surface Water Quality 
Regulations amended on September 30, 1996.

B. 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 degradation of 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 RSA 485-A:8, VI Part Env-
Ws 430.31 through 430.45.
    This general permit does not apply to any new or increased 
discharge to any outstanding national resource water or the territorial 
seas. It also does not apply to any new or increased discharge to other 
waters unless the discharge is shown to be consistent with the state's 
antidegradation policies. This determination shall be made in 
accordance with the appropriate State Antidegradation implementation 
procedures. EPA will not authorize these discharges under the general 
permit until it receives a favorable

[[Page 24198]]

antidegradation review and certification from the States.

C. Monitoring and Reporting Requirements

    Effluent limitations and monitoring requirements which are included 
in the general permit describe the requirements to be imposed on the 
facilities to be covered.
    Facilities covered by the final general permits will be required to 
submit to EPA, New England Region and the appropriate State authority, 
a Discharge Monitoring Report (DMR) containing effluent data. The 
frequency of reporting is determined in accordance with each State's 
provisions (see the individual State permits).
    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.

D. Endangered Species

    The proposed limits are sufficiently stringent to assure water 
quality standards, both for aquatic life protection and human health 
protection, will be met. The effluent limitations established in these 
permits ensure protection of aquatic life and maintenance of the 
receiving water as an aquatic habitat. The Region finds that adoption 
of the proposed permits is unlikely to adversely affect any threatened 
or endangered species or its critical habitat. EPA is seeking written 
concurrence from the United States Fish and Wildlife Service and 
National Marine Fisheries Service on this determination.

E. Standard Permit Condition

    40 CFR 122.41 and 122.42 must be complied with. Specific language 
will be provided to permittees in part II of the permit.

F. State (401) 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 is underway in all 
States. In addition, EPA and the Commonwealth of Massachusetts jointly 
issue the final permit.

G. The Coastal Zone Management Act

    The Coastal Zone Management Act (CZMA), 16 U.S.C. 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. In the case of general permits, EPA has the 
responsibility for making the consistency certification and submitting 
it to the state for concurrence. EPA has requested the MEDEP, Division 
of Water Resource Regulation, 17 State House, Augusta, ME 04333; the 
Executive Office of Environmental Affairs, MACZM, 100 Cambridge Street, 
Boston, MA 02202; and the Office of State Planning, New Hampshire 
Coastal Program, 2\1/2\ Beacon Street, Concord, NH 03301, to provide a 
consistency concurrence that the proposed general permit is consistent 
with the ME, MA and NH Coastal Zone Management Program respectively.

H. Environmental Impact Statement Requirements

    The general permits do not authorize discharges from any new 
sources as defined under 40 CFR 122.2. Therefore, the National 
Environmental Policy Act, 33 U.S.C. 4321 et seq., does not apply to the 
issuance of these general NPDES permits.

I. National Historic Preservation Act of 1966

    Facilities which adversely affect properties listed or eligible for 
listing in the National Registry of Historic Places under the National 
Historic Preservation Act of 1966, 16 U.S.C. SS470 et. seq. are not 
authorized to discharge under this permit.

J. Essential Fish Habitat

    The proposed limits are sufficiently stringent to assure state 
water quality standards, both for aquatic life protection and human 
health protection, will be met. The effluent limitations established in 
these permits ensure protection of aquatic life and maintenance of the 
receiving water as an aquatic habitat. The Region finds that adoption 
of the proposed permits is unlikely to adversely affect any federally 
managed species for which essential fish habitat has been designated. 
EPA is seeking written concurrence from the National Marine Fisheries 
Service on this determination.

V. Other Legal Requirements

A. Executive Order 12866

    EPA has determined that this general permit is not a ``significant 
regulatory action'' under the terms of Executive Order 12866 and is 
therefore not subject to OMB review.

B. Paperwork Reduction Act

    The information collection requirements of this permit were 
previously approved by the Office of Management and Budget under the 
provisions of the Paperwork Reduction Act. 44 U.S.C. 3501 et seq., and 
assigned OMB control number 2040-0086 (NPDES permit application) and 
2040-0004 (Discharge Monitoring Reports).

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA), 5 U.S.C. 601 et seq., 
requires that EPA prepare a regulatory flexibility analysis for rules 
subject to the requirements of 5 U.S.C. 553(b) that have a significant 
impact on a substantial number of small entities. The permit issued 
today, however, is not a ``rule'' subject to the requirements of 5 
U.S.C. 553(b) and is therefore not subject to the Regulatory 
Flexibility Act.

D. Unfunded Mandates Reform Act

    Section 201 of the Unfunded Mandates Reform Act (UMRA), Public Law 
104-4, generally requires Federal agencies to assess the effects of 
their ``regulatory actions'' (defined to be the same as ``rules'' 
subject to the RFA) on tribal, state and local governments and the 
private sector. The permit issued today, however, is not a ``rule'' 
subject to the RFA and is therefore not subject to the requirements of 
UMRA.

Part I--Final General Permits Under the National Pollutant 
Discharge Elimination System (NPDES)

    Note: The following three final general permits have been 
combined for purposes of this Federal Register. Part I A, part I B 
and part I C contain general permits for the states of ME, MA 
(including both Commonwealth and Indian Country lands), and NH 
respectively. Part I.D. is common to all three permits.

A. Maine General Permit, Permit No. MEG250000

    In compliance with the provisions of the Federal Clean Water Act, 
as amended, (33 U.S.C. 1251 et seq.; the ``CWA''), operators of 
industrial facilities discharging non-contact cooling water located in 
Maine are

[[Page 24199]]

authorized to discharge to all waters of the State unless otherwise 
restricted by Title 38, Article 4-A, Water Classification Program, in 
accordance with effluent limitations, monitoring requirements and other 
conditions set forth herein. No discharge into lakes is authorized by 
this permit. The permit allows non-contact cooling water to be 
commingled with other discharges as long as the non-contact cooling 
water can be monitored separately for compliance. In Maine the General 
NPDES Permit is not available to dischargers in Indian Country. EPA 
will in the near future be making a decision regarding whether State 
law applies in Indian Country in Maine for the purposes of water 
quality regulation in response to the State's application to implement 
the NPDES Permit program in Indian Country. Until then we will not know 
from whom to accept section 401 of the Clean Water Act certification 
and so are not making the permit available in Indian Country.
    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 
and supersedes the permit issued on April 28, 1994.

    Signed this 14th day of April, 2000.
Edward K. McSweeney,
Acting Director, Office of Ecosystem Protection, Environmental 
Protection Agency, Boston, MA 02114.
Effluent Limitations and Monitoring Requirements
    1. During the period beginning on the effective date and lasting 
through expiration, the permittee is authorized to discharge non-
contact cooling water.
    a. Each outfall discharging non-contact cooling water shall be 
limited and monitored as specified below. Monitoring for each outfall 
shall be reported.

----------------------------------------------------------------------------------------------------------------

    b. The discharge shall not cause a violation of the water quality 
standards.
    c. Non-contact cooling water may be discharged only into Class B, 
C, SB, and SC waters that have a drainage area larger than ten (10) 
square miles in accordance with Maine State Law. See part I.A.1.h. for 
details for determining if the specific discharge(s) have acceptable 
dilution and can be covered by the General Permit Program.
    d. The pH of the effluent shall not be less than 6.0 standard units 
nor greater than 8.5 standard units any time unless these values are 
exceeded due to natural causes or as a result of an approved treatment 
process. pH shall be monitored monthly with 4 grabs, reporting maximum 
and minimum values.
    e. There shall be no discharge of floating solids or visible foam 
in other than trace amounts.
    f. Samples taken in compliance with the monitoring requirements 
specified above shall be taken at a location that provides a 
representative analysis of the effluent just prior to discharge to the 
receiving water or if the effluent is commingled with another permitted 
discharge, prior to such commingling.
    g. Water Treatment Additives. Non-toxic water treatment additives 
are chemicals used in cooling water systems primarily to control 
corrosion or prevent deposition of scale forming materials which do not 
exhibit any residual toxic effect on the receiving waters. No treatment 
additives may be used until specifically reviewed and authorized by 
MEDEP. Non-toxic water treatment additives are allowed in non-contact 
cooling water systems. The State of Maine will review each identified 
chemical to determine its acceptability. Additives used to control 
biological growth in such cooling systems are prohibited due to their 
inherent toxicity to aquatic life.
    The following water treatment additive biological and chemical data 
must be supplied in the letter of intent to be covered by this general 
permit:
    (1) Name and manufactureR of each additive used,
    (2) Maximum and average daily quantity of each additive used on a 
monthly basis, and
    (3) The vendor's reported aquatic toxicity of additive (NOAEL and/
or LC50 in % for typically acceptable aquatic test 
organisms).
    All substitutions to the accepted water treatment chemicals must be 
approved by the State prior to their usage.
    h. Discharge Temperature and Volume. The temperature and total 
volume of the discharge from each facility shall not exceed 120  deg.F 
and 3.0 million gallons per day (MGD). The acceptability of the 
discharge from each facility must be determined using the graph on 
Figure I. The intersection of the maximum effluent temperature and the 
dilution ratio shall be in the ``acceptable'' range shown on Figure I, 
titled ``Effluent Temperature/Dilution Graph'' for coverage by the 
General Permit. If the intersection falls within the ``non-acceptable'' 
area, the facility must be covered by an individual NPDES Permit, not 
the General Permit.
    The effluent temperature is the maximum daily temperature. The 
dilution factor is the sum of the 7Q10 low stream flow at the facility 
site and the daily maximum effluent flow divided by the daily maximum 
effluent flow. For facilities with multiple outfalls, the daily maximum 
effluent flow shall be the sum of the flow from all outfalls.
    i. Total Residual Chlorine. Potable water supply sources used for 
cooling water supply shall not contain Total Residual Chlorine (TRC) at 
concentration levels that induce a toxic impact upon aquatic life 
within the receiving waters. The instream waste concentration of TRC 
based on the ratio of the effluent flow stream flow to the 7Q10 low 
flow of the stream shall be less than the appropriate water quality 
criteria ( acute = 19 g/l, chronic = 11 ug/l for fresh water 
and acute = 13 g/l, chronic = 7.5 g/l for marine 
water) for the receiving waterway.
    j. In the case of suspected toxicity, chronic (and modified acute) 
toxicity test(s) shall be performed on the non-contact cooling water 
discharge by the permittee upon request by EPA and/or MEDEP. Testing 
shall be performed in accordance with EPA toxicity protocol to be 
provided at the time of the request. The test shall be performed on a 
24 hour composite sample to be taken during normal facility operation. 
The result of

\1\ The State with EPA concurrence may allow coverage under the general permit for discharges greater than 1.0
  MGD when it determines that such discharge is consistent with all the terms and conditions of the permit on a
  case by case basis without violating surface water quality standards.
\2\ The definition of a cold or warm water fishery can be found in the Massachusetts Surface Water Quality
  Standards, 314 CMR 4.02.
\3\ Samples shall be taken immediately upstream and downstream of the discharge (allowing for resaonable
  mixing), once per quarter to ensure that receiving water temperature rise limits are being complied with.

    b.* * * The discharge shall not cause a violation of the water 
quality standards.
    c.* * * The rise in temperature due to a discharge to Class A 
waters shall not exceed 1.5 deg.F (0.8 deg.C); and natural seasonal and 
daily variations shall be maintained (314CMR4.05(3)(a)2).
    d.* * * The rise in temperature due to a discharge to Class B 
waters shall not exceed 3 deg.F (1.7 deg.C) in rivers and streams 
designated as cold water fisheries nor 5 deg.F (2.8 deg.C) in rivers 
and streams designated as warm water fisheries (based on the minimum 
expected flow for the month); in lakes and ponds the rise shall not 
exceed 3 deg.F (1.7 deg.C) in the epilimnion (based on the monthly 
average of maximum daily temperature); and natural seasonal and daily 
variations shall be maintained (314 CMR 4.05(3)(b)2).
    e.* * * The rise in temperature due to a discharge to Class SA 
waters shall not exceed 1.5 deg.F (0.8 deg.C); and natural seasonal and

specified above shall be taken at a location that provides a 
representative analysis of the effluent just prior to discharge to the 
receiving water or if the effluent is commingled with another 
discharge, prior to such commingling. Samples shall be spaced 
throughout the operating day and at times representative of temperature 
fluctuations in the discharge.
    i. The pH of the effluent for discharges to Class A and Class B 
waters shall be in the range of 6.5-8.3 standard units and not more 
than 0.5 units outside of the background range. There shall be no 
change from background conditions that would impair any uses assigned 
to the receiving water Class.
    j. The pH of the effluent for discharges to Class SA and Class SB 
waters shall be in the range of 6.5-8.5 standard units and not more 
than 0.2 units outside of the normally occurring range. There shall be 
no change from background conditions that would impair any uses 
assigned to the receiving water Class.

[[Page 24203]]

    k. Chronic (and modified acute) toxicity test(s) shall be performed 
on the non-contact cooling water discharge by the permittee upon 
request by EPA and/or MADEP. Testing shall be performed in accordance 
with EPA toxicity protocol to be provided at the time of the request.

\1\ The State with EPA concurrence may allow coverage under the general permit for discharges greater than 1.0 mgd when it determines that such
  discharge is consistent with all the terms and conditions of the permit on a case by case basis without violating surface water quality standards.
\2\ As determined by the New Hampshire Fish and Game Department.

    b. The discharge shall not cause a violation of the water quality 
standards of the receiving water.
    c. This permit does not allow the addition of any chemical for any 
purpose to the water except for non-toxic pH neutralization chemicals. 
The State of New Hampshire will review each identified pH 
neutralization chemical to determine its acceptability. In addition, 
additives used to control biological growth, corrosion, and/or scale in 
cooling water are prohibited due to their inherent toxicity to aquatic 
life.
    For each non-toxic pH neutralization chemical used the following 
data must be supplied with the Notice Of Intent

[[Page 24204]]

letter to be covered by this general permit.
    (1) Name and manufacturer,
    (2) Maximum and average daily quantity used on a monthly basis as 
well as the maximum and average daily expected concentrations (mg/l) in 
the cooling water, and
    (3) The vendor's reported aquatic toxicity (NOAEL and/or 
LC50 in percent for typically acceptable aquatic 
organism(s)).
    All substitutions of non-toxic pH neutralization chemicals must be 
approved by the State in writing prior to their usage. All written 
substitution requests must contain the information required in part 
I.C.1.c.(1)-(3) immediately above.
    d. There shall be no discharge of oil, floating solids, foam, 
debris or other visible pollutants.
    e. Samples taken in compliance with the monitoring requirements 
specified above shall be taken at a location that provides a 
representative analysis of the effluent just prior to discharge to the 
receiving water or, if the effluent is commingled with another 
permitted discharge, prior to such commingling.
    f. One chronic (and modified acute) toxicity test shall be 
performed on the non-contact cooling water discharge by the permittee 
upon request by EPA and/or the NHDES. Testing shall be performed in 
accordance with EPA toxicity protocol to be provided at the time of the 
request. The test shall be perrformed on a 24-hour composite sample to 
be taken during normal facility operation. The results of the test (C-
NOEC and LC50) shall be forwarded to the State and EPA 
within 30 days after completion.
    g. The permittee may submit a written request to the EPA requesting 
a change in the permitted pH limit range to be not less restrictive 
than any applicable federal effluent guideline for the facility or to a 
default range of 6.0 to 9.0 S.U. in the situation of no applicable 
guideline, whichever is more stringent. The permittee's written request 
must include the State's letter containing an original signature (no 
copies). The State's letter shall state that the permittee has 
demonstrated to the State's satisfaction that as long as discharges to 
the receiving water from a specific outfall are within a specific 
numeric pH range the naturally occurring receiving water pH will be 
unaltered. That letter must specify for each outfall the associated 
numeric pH limit range. Until written notice is received by certified 
mail from the EPA indicating the pH limit range has been changed, the 
permittee is required to meet the permitted pH limit range in the 
respective permit.
2. State Permit Conditions
    a. The permittee shall comply with the following conditions which 
are included as State Certification requirements.

    The pH range for class B waters shall be 6.5-8.0 S.U. or as 
naturally occurs in the receiving water. The 6.5-8.0 S.U. range must 
be achieved in the final effluent unless the permittee can 
demonstrate to Division that: (1) The range should be widened due to 
naturally occurring conditions in the receiving water or (2) the 
naturally occurring source water pH is unaltered by the permittees 
operation. The scope of any demonstration project must receive prior 
approval from the Division.

    b. This NPDES Discharge Permit is issued by the U.S. Environmental 
Protection Agency under Federal and State law. Upon final issuance by 
the EPA, the New Hampshire Department of Environmental Services, 
Surface Water Quality Bureau, may adopt this Permit, including all 
terms and conditions, as a state permit pursuant to RSA 485-A:13.

D. Common Elements for all Permits

1. Description of Non-Contact Cooling Water Discharges
    Non-contact cooling water is water used to reduce temperature which 
does not come into direct contact with any raw material, intermediate 
product, waste product (other than heat) or finished product. Non-
contact cooling water discharges are similar in composition even though 
they are not generated by a single industrial category or point source. 
For further definition of noncontact cooling water see 40 CFR 401.11 
(n).
2. Conditions of the General NPDES Permit
    a. Geographic Areas: Maine (Permit No. MEG250000). All of the 
discharges to be authorized by the general NPDES permit for dischargers 
located in the State of Maine are into all waters of the State unless 
otherwise restricted by Title 38, Article 4-A, Water Classification 
Program (or as revised). In Maine the General NPDES Permit is not 
available to dischargers in Indian Country. EPA will in the near future 
be making a decision regarding whether State law applies in Indian 
Country in Maine for the purposes water quality regulation in response 
to the State's application to implement the NPDES Permit program in 
Indian Country. Until then we will not know from whom to accept section 
401 of the Clean Water Act certification and so are not making the 
permit available in Indian Country.
    Massachusetts (Permit No. MAG250000). All of the discharges to be 
authorized by the general NPDES permit for dischargers in the 
Commonwealth of Massachusetts are into all waters of the Commonwealth 
and Indian Country lands unless otherwise restricted by the 
Massachusetts Surface Water Quality Standards, 314 CMR 4.00 (or as 
revised), including 314 CMR 4.04(3) Protection of Outstanding Resource 
Waters.
    New Hampshire (Permit No. NHG250000). All of the discharges to be 
authorized by the general NPDES permit for dischargers in the State of 
New Hampshire 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 non-contact cooling water and whose 
facilities are located in the geographic areas described in part I.D.2. 
above, may submit to the Regional Administrator, EPA--New England, a 
notice of intent to be covered by the appropriate general permit. 
Notifications must be submitted by permittees who are seeking coverage 
under this permit for the first time and by those permittees who 
received coverage under the expired permit. This written notification 
must include for each individual facility, the owner's and/or 
operator's legal name, address and telephone number; the facility name, 
address, contact name and telephone number; the number and type of 
facilities (SIC code) to be covered; the facility location(s); a 
topographic map (or other map if a topographic map is not available) 
indicating the facility location() and discharge point(s); latitude and 
longitude of outfall(s); the name(s) of the receiving waters into which 
discharge will occur; the source of noncontact cooling water i.e., 
river intake, (cooling water intake structures shall reflect best 
technology available for minimizing adverse environmental impact), 
municipal water supply or private well etc.; an antidegradation review 
where necessary see section IV. B of the Fact Sheet); new and increased 
discharges of non-contact cooling water 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 (see 
section IV. D of the Fact Sheet); and if required, a special list of 
water treatment chemicals used by the facility. The notice must be 
signed in accordance with the signatory requirements of 40 CFR 122.22.
    Facilities located in Maine, Massachusetts and New Hampshire that

[[Page 24205]]

intend to be covered under this general permit must also submit a 
formal certification with the notice of intent that no chemical 
additives except those used for pH adjustment are used in their non-
contact cooling water systems. If non-toxic neutralization chemicals 
are used, each shall be listed in the Notice of Intent letter.
    Each facility must certify that the discharge for which it is 
seeking coverage under this general permit consists solely of non-
contact cooling water and any authorized water treatment chemicals. If 
the discharge of non-contact cooling water subsequently mixes with 
other wastewater (e.g. stormwater) prior to discharging to receiving 
water, the permittee must certify that the monitoring it will provide 
under this general permit will be only for contact cooling water. An 
authorization to discharge under this general permit, where the non-
contact cooling water discharges to a municipal or private storm drain 
owned by another party, does not convey any rights or authorization to 
connect to that drain.
    Each facility must also submit a copy of the notice of intent to 
each State authority as appropriate (see individual state permits for 
appropriate authority and address).
    The facilities authorized to discharge under the final general 
permit will receive written notification from EPA, New England Region, 
with State concurrence. Failure to submit to EPA, New England Region , 
a notice of intent to be covered and/or failure to receive from EPA 
written notification of permit coverage means that the facility is not 
authorized to discharge under this general permit.
3. 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.
    b. Eligibility to Apply: Any facility operating under an effective 
(unexpired) individual NPDES permit may request that the individual 
permit be revoked and that coverage under the general permit be 
granted, as outlined in 40 CFR 122.28(b)(3)(v).If EPA revokes the 
individual permit, the general permit would apply to the discharge.
    Facilities with expired individual permits that have been 
administratively continued in accordance with 40 CFR 122.6 may apply 
for coverage under this general permit. When coverage is granted the 
expired individual permit automatically will cease being in effect. 
Proposed new dischargers may apply for coverage under this general 
permit and must submit the NOI 90 days prior to the discharge.
    Facilities with coverage under the current general permit issued on 
April 28, 1994, effective on May 31, 1994 and expired on May 31, 1999 
need to apply for coverage under this general permit within 60 days 
from the effective date of the permit. Failure to submit a Notice of 
Intent within 60 days for continuation of the discharge will be 
considered discharging without a permit as of the expiration date of 
the expired permit (May 31, 1999) for enforcement purposes. A Notice of 
Intent is not required if the permittee submits a Notice of Termination 
(see part I.F.1) of discharge before the sixty days expires.
    c. Continuation of this General Permit after expiration: If this 
permit is not reissued prior to the expiration date, it will be 
administratively continued in accordance with the Administrative 
Procedures Act and remain in force and in effect as to any particular 
permittee as long as the permittee submits a new Notice of Intent two 
(2) months prior to the expiration date in the permit. However, once 
this permit expires EPA cannot provide written notification of coverage 
under this general permit to any permittee who submits Notice of Intent 
to EPA after the permit's expiration date. Any permittee who was 
granted permit coverage prior to the expiration date will automatically 
remain covered by the continued permit until the earlier of:
    (1) Reissuance of this permit, at which time the permittee must 
comply with the Notice of Intent conditions of the new permit to 
maintain authorization to discharge; or
    (2) The permittee's submittal of a Notice of Termination; or
    (3) Issuance of an individual permit for the permittee's 
discharges; or
    (4) A formal permit decision by the Director not to reissue this 
general permit, at which time the permittee must seek coverage under an 
alternative general permit or an individual permit.

F. Summary of Responses to Public Comments

    On November 23, 1999, EPA released in the Federal Register for 
public notice and comment a draft NPDES general permit for non-contact 
cooling water discharges in the states of ME, MA. and NH. The public 
comment period for this draft general permit expired on December 22, 
1999.
    1. Based on EPA in-house review and comment, the following items 
are changed with the concurrence of the respective states where 
appropriate:
    A. Under section III--Exclusions, the first paragraph is changed to 
read as follows: ``This general permit is not available to facilities 
which have cooling water intake structures that do not reflect the best 
technology available for minimizing adverse environmental impact, as 
required by section 316(b) of the Clean Water Act. This general permit 
is also not available to those facilities seeking alternative thermal 
limitations pursuant to section 316(a) of the Clean Water Act.''
    B. Under part I.A.1.a. (ME Permit), Effluent Limitations and 
Monitoring Requirements for pH and LC50 & C-NOEC are added. 
A new note ``j'' for toxicity testing is also added under part I.A.1.j.
    C. Under part I.C.1.a (NH Permit), maximum daily flow is changed 
from ``Report'' to 1.0 mgd with the following note: ``The State with 
EPA concurrence may allow coverage under this general permit for 
discharges greater than 1.0 mgd when it determines that such discharge 
is consistent with the terms and conditions of the permit on a case by 
case basis without violating surface water quality standards.''
    D. Under part I Final General Permits and part I.D.2.a., Geographic 
Areas language is added to clarify that the general permit in Maine is 
not available for discharges in Indian Country and to clarify that 
Indian Country lands are included in the Commonwealth of Massachusetts 
permit.
    E. Under part I.D.2.b, Notification by Permittee, the following: 
``(cooling water intake structures shall reflect best technology 
available for minimizing adverse environmental impact)'' is added after 
``* * * cooling water i.e, river intake * * *'' on line 11.
    2. The following items are either added or changed based on 
comments from the State of New Hampshire :
    A. pH is added before all ``neutralization chemicals'' under part 
I.C.1.c.
    B. In the last line of the third paragraph under part I.D.3.b, 
Eligibility to Apply, the word ``Notice of Termination'' is followed by 
the reference part I.F.1.
    C. The reference to the ``Surface Water Quality Bureau'' is 
replaced with ``Water Division''.
    3. Based on comments from MADEP the following items are either 
added or changed :
    A. Under part I.B.1.g. the wording is changed to read ``* * * 
floating solids, visible oil sheen or foam other than in trace 
amounts.''
    B. Under part I.B.1.h, add: ``Samples shall be spaced throughout 
the operating day and at times representative of temperature 
fluctuations in the discharge.''
    C. Under part I.E.2.b. the wording is changed to read ``Copies of 
all DMRs, toxicity tests and other notifications * * *'' instead of 
``except DMRs.''
    4. The US Fish and Wildlife Service, in a letter dated December 17, 
1999, concurred with EPA's opinion that the reissuance of the NPDES 
general permits will not jeopardize the continued existence of Atlantic 
salmon in Maine.
    5. The National Marine Fisheries Service in a letter dated April 5, 
2000 has concluded that the reissuance of the

[[Page 24207]]

general permits for the discharge of non-contact cooling water in the 
states of Maine, Massachusetts and New Hampshire will not likely 
adversely affect any endangered or threatened species under NMFS 
jurisdiction. NMFS also concurs with EPA's determination that this 
action will not have an adverse effect on essential fish habitat.

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 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 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 section 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 notice of intent 
at least 60 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 parts 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

[[Page 24208]]

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

[[Page 24209]]

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 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 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 
section 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 section 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 
reported within 24 hours. (See section 122.44(g))
    (3) The Regional Administrator may waive the written report on a 
case-by-case basis for reports under paragraph D.1.e if the oral report 
has been received within 24 hours.
    f. Compliance Schedules. Reports of compliance or noncompliance 
with, or any progress reports on, interim and final requirements 
contained in any compliance schedule of this permit shall be submitted 
no later than 14 days following each schedule date.
    g. Other noncompliance. The permittee shall report all instances of 
noncompliance not reported under paragraphs D.1.d, D.1.e and D.1.f of 
this section, at the time monitoring reports are submitted. The reports 
shall contain the information listed in paragraph D.1.e of this 
section.
    h. Other information. Where the permittee becomes aware that it 
failed to submit any relevant facts in a permit application, or 
submitted incorrect information in a permit application or in any 
report to the Regional Administrator, it shall promptly submit such 
facts or information.
2. Signatory Requirement
    a. All applications, reports, or information submitted to the 
Regional Administrator shall be signed and certified. (See section 
122.22)
    b. The CWA provides that any person who knowingly makes any false 
statement, representation, or certification in any record or other 
document submitted or required to be maintained under this permit, 
including monitoring reports or reports of compliance or non-compliance 
shall, upon conviction, be punished by a fine of not more than $10,000 
per violation, or by imprisonment for not more than 6 months per 
violation, or by both.
3. Availability of Reports
    Except for data determined to be confidential under paragraph A.8. 
above, all reports prepared in accordance with the terms of this permit 
shall be available for public inspection at the offices of the State 
water pollution control agency and the Regional Administrator. As 
required by the CWA, effluent data shall not be considered 
confidential. Knowingly making any false statement on any such report 
may result in the imposition of criminal penalties as provided for in 
section 309 of the CWA.
