Fact Sheet and Supplemental Information

I. Introduction

The Director of the Office of Ecosystem Protection, EPA-New England, is issuing final general permits for water treatment facility discharges to certain waters of the States of Massachusetts and New Hampshire. This document contains part I of 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 are generally 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 December 9, 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

EPA has 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.

EPA has determined that this general permit will not be available for discharge(s) into the impaired water on the Federal Clean Water Act 303(d) list which are not attaining state water quality standards.

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 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 or in violation of State Water Quality Standards for the receiving water.

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. Types of Discharge

Under this general permit, owners and operators of potable water treatment plants in Massachusetts 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 aluminium compounds or polymers as coagulants; and

c. Treated filter backwash water from filters.

This general 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.

B. 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 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 water treatment facility discharges. EPA also 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 Massachusetts and New Hampshire have narrative criteria in their water quality regulations. See Massachusetts 314 CMR 4.05(5)(e) and New Hampshire Part Env-Ws 1703.21 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.

Water quality standards applicable to water treatment facility discharges covered by this general permit include TSS and pH for all states. The limitations for TSS and pH are based upon limitations in the existing permit in accordance with the anti-backsliding requirements found in 40 CFR 122.44(1). A summary of the limits and testing requirements for each state is described below:

Massachusetts and New Hampshire: Limits of monthly average and maximum daily TSS and pH. Testing requirements for Chlorine, Aluminum, LC50 and C-NOEC.

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.B.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.B.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.B.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 December 10, 1999.

C. 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: Massachusetts Water Quality Standards 314 CMR 4.04 Antidegradation Provisions; and New Hampshire RSA 485-A:8, VI Part Env-Ws 1708.

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 antidegradation review and certification from the States.

D. 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.

E. Endangered Species

The 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 final permits is unlikely to adversely affect any threatened or endangered species or its critical habitat. EPA has consulted with the United States Fish and Wildlife Service and National Marine Fisheries Service on this determination and has received concurrences from them.

F. 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.

G. 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 complete and EPA has received 401 certifications from all States. In addition, EPA and the Commonwealth of Massachusetts jointly issue the final permit.

H. 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 Executive Office of Environmental Affairs, MACZM, 100 Cambridge Street, Boston, MA 02202; and the Office of State Planning, New Hampshire Coastal Program, 21/2 Beacon Street, Concord, NH 03301, to provide a consistency concurrence that the proposed general permit is consistent with the MA and NH Coastal Zone Management Program respectively and EPA has received consistency concurrences from all states.

I. 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.

J. National Historic Preservation Act of 1966, 16 U.S.C. SS470 et seq.

Facilities which adversely affect properties listed or eligible for listing in the National Registry of Historic Places under the National Historic Preservation Act of 1996, 16 U.S.C. SS470 et seq. are not authorized to discharge under this permit.

K. Essential Fish Habitat

Under the 1996 Amendments (Public Law 104-267) to the Magnuson-Stevens Fishery Conservation and Management Act (16 U.S.C. 1801 et seq. (1998)), EPA is required to consult with NMFS if EPA's action or proposed actions that it funds, permits or undertakes, “may adversely impact any essential fish habitat.” 16 U.S.C. 1855(b). The Amendments broadly define “essential fish habitat” (EFH) as “waters and substrate necessary to fish for spawning, breeding, feeding or growth to maturity.” 16 U.S.C. 1802(10). Adverse impact means any impact which reduces the quality and/or quantity of EFH 50 CFR 600.910(a). Adverse effects may include direct (e.g., contamination or physical disruption), indirect (e.g., loss of prey, reduction in species' fecundity), site-specific or habitat-wide impacts, including individual, cumulative or synergistic consequences of actions.

Essential Fish Habitat is only designated for fish species for which federal Fisheries Management Plans exist. 16 U.S.C. 1855(b)(1)(A). EFH designations for New England were approved by the U.S. Department of Commerce on March 3, 1999.

The limits for this general permit are sufficiently stringent to assure that state water quality standards 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 fish or shellfish currently listed with a Fisheries Management Plan or its critical habitat. EPA sought written concurrence from the National Marine Fisheries Service on this determination and incorporated their comments in section III ( Exclusions), 2nd paragraph of the Fact Sheet and part I.E.2.(8) of the permit.

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.

The results of the test (C-NOEC and LC₅₀) shall be forwarded to State and EPA within 30 days after completion.

State Permit Conditions

1. This Discharge Permit is issued jointly by the U.S. Environmental Protection Agency (EPA) and the Department of Environmental Protection under Federal and State law, respectively. As such, all the terms and conditions of this permit are hereby incorporated into and constitute a discharge permit issued by the Director of the Massachusetts Division of Watershed Management pursuant to M.G.L. Chap. 21, section 43.

2. Each Agency shall have the independent right to enforce the terms and conditions of this Permit. Any modification, suspension or revocation of this Permit shall be effective only with respect to the Agency taking such action, and shall not affect the validity or status of this Permit as issued by the other Agency, unless and until each Agency has concurred in writing with such modification, suspension or revocation. In the event any portion of this Permit is declared, invalid, illegal or otherwise issued in violation of State law such permit shall remain in full force and effect under Federal law as an NPDES Permit issued by the U.S. Environmental Protection Agency. In the event this Permit is declared invalid, illegal or otherwise issued in violation of Federal law, this Permit shall remain in full force and effect under State law as a Permit issued by the Commonwealth of Massachusetts.

B. New Hampshire General Permit

[Permit No. NHG640000]

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 discharging effluent from water treatment facility located in New Hampshire are authorized to discharge to all waters, unless otherwise restricted by State Water Quality Standards, New Hampshire RSA 485-A:8, in accordance with effluent limitations, monitoring requirements and other conditions set forth herein. The permit allows effluent from water treatment facility to be commingled with other discharges as long as the effluent from water treatment facility can be monitored separately for compliance.

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 December 9, 1994.

Signed this 2nd day of November, 2000.

1 Samples shall be taken only when discharging.
2 Test and report only if chlorination is used in the process.
3 LC-50 is the concentration of effluent in a sample that causes mortality to 50% of the test population at a specific time of observation. C-NOEC, No Observed Chronic Effect Concentration, is the highest concentration of effluent to which organisms are exposed in a life-cycle or partial life-cycle test which cause no adverse effect on growth, survival and reproduction at a specific time of observation as determined from hypothesis testing where the test results (growth, survival and/or reproduction) exhibit a linear dose-response relationship. However, where the test results do not exhibit a linear dose-response relationship, report the lowest concentration where there is no observable effect.

b. The discharge shall not cause a violation of the water quality standards of the receiving water.

c. The discharge shall be adequately treated to insure that the surface water remains free from pollutants in concentrations or combinations that settle to form harmful deposits, float as foam, debris, scum or other visible pollutants. It shall be adequately treated to insure that the surface waters remain free from pollutants which odor, color, taste or turbidity in the receiving water which is not naturally occurring and would render it unsuitable for its designated uses.

d. 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.

e. 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.

f. One chronic (and modified acute) toxicity test shall be performed on the water treatment facility's 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 performed 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.

2. State Permit Conditions

a. The permittee shall comply with the following conditions which are included as State Certification requirements.

(1) 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, Water Division, may adopt this Permit, including all terms and conditions, as a state permit pursuant to RSA 485-A:13.

C. Common Elements for All Permits:

1. Conditions of the General NPDES Permit

a. Geographic Areas.

• Massachusetts (Permit No. MAG640000). 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 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. NHG640000). 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 effluent from water treatment facilities and whose facilities are located in the geographic areas described in part I.C.1.a 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(s)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 water i.e., river intake, private well etc. to be treated; an antidegradation review where necessary see section IV. C of the Fact Sheet; new and increased discharges from water treatment facility 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.E of the Fact Sheet); and a 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.

Each facility must certify that the discharge for which it is seeking coverage under this general permit consists solely of effluent from discharges from the water treatment facilities. If the discharge of the water treatment facility subsequently mixes with other wastewater (e.g. stormwater) prior to discharging to a receiving water, the permittee must certify that the monitoring it will provide under this general permit will be only for water treatment facility. An authorization to discharge under this general permit, where the water treatment facility 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.

2. 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 December 9, 1994, effective on January 9, 1995 and expired on January 9, 2000 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 (January 9, 2000) 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.

(5) A Water Quality Management Plan or Total Maximum Daily Load containing requirements applicable to such point source is approved;

(6) Discharge to the territorial sea

(7) Discharge to outstanding natural resource water.

(8) Discharge into waters that are not attaining state water quality standards.

(9) The point source(s) covered by this permit no longer:

(a) Involves the same or substantially similar types of operations;

(b) Discharges the same types of wastes;

(c) Requires the same effluent limitations or operating conditions;

(d) Requires the same or similar monitoring; and

(e) In the opinion of the Director, is more appropriately controlled under a general permit than under an individual NPDES permit.

b. The Director may require an individual permit only if the permittee authorized by the general permit has been notified in writing that an individual permit is required, and has been given a brief explanation of the reasons for this decision.

3. When an Individual NPDES Permit May Be Requested.

a. Any operator may request to be excluded from the coverage of this general permit by applying for an individual permit.

b. When an individual NPDES permit is issued to an operator otherwise subject to this general permit, the applicability of this permit to that owner or operator is automatically terminated on the effective date of the individual permit.

F. Summary of Responses to Public Comments

On June 30, 2000, EPA released in the Federal Register for public notice and comment a draft NPDES general permit for effluent from water treatment facility discharges in the states of ME, MA. and NH. The public comment period for this draft general permit expired on July 30, 2000.

1. The US Fish and Wildlife Service, in a letter dated August 1, 2000, concurred with EPA's opinion that the reissuance of the NPDES general permits will not jeopardize the continued existence of Atlantic salmon in Maine.

2. The National Marine Fisheries Service in a letter dated July 31, 2000 has commented that the discharge into waters that are not attaining state water quality standards should be excluded from this permit . EPA concurs with NMFS. Accordingly section III (Exclusions), 2nd paragraph of the Fact Sheet and part I.F.2.(8) of the permit are added. Otherwise, NMFS has concluded that reissuance of the general permits for the water treatment facility discharge(s) in the states of Massachusetts and New Hampshire will not likely adversely affect any endangered or threatened species including essential fish habitat under NMFS jurisdiction.

3. The State of Maine, in a letter dated August 29, 2000 has requested EPA to be excluded from this general permit. EPA agrees and the permit for the State of Maine ( MEG640000) is taken out from this general permit.

4. Based on comments from MA DEP some address corrections are made in the draft permit.

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 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 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, not 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.

Section E—Other Conditions

1. Definitions for purposes of this permit are as follows:

Administrator means the Administrator of the United States Environmental Protection Agency, or an authorized representative.

Applicable standards and limitations means all State, interstate, and Federal standards and limitations to which a “discharge” or a related activity is subject to, including water quality standards, standards of performance, toxic effluent standards or prohibitions, “best management practices,” and pretreatment standards under sections 301, 302, 303, 304, 306, 307, 308, 403, and 405 of CWA.

Application means the EPA standard national forms for applying for a permit, including any additions, revisions or modifications to the forms; or forms approved by EPA for use in “approved States,” including any approved modifications or revisions.

Average means the arithmetic mean of values taken at the frequency required for each parameter over the specified period. For total and/or fecal coliforms, the average shall be the geometric mean.

Average monthly discharge limitation means the highest allowable average of “daily discharges” over a calendar month, calculated as the sum of all daily discharges measured during a calendar month divided by the number of daily discharges measured during that month.

Average weekly discharge limitation means the highest allowable average of “daily discharges” over a calendar week, calculated as the sum of all daily discharges measured during a calendar week divided by the number of daily discharges measured during that week.

Best Management Practices (BMPs) means schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of “waters of the United States.” BMPs also include treatment requirements, operating procedures, and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
