WATER COMPLIANCE UNIT 7 DIVISION OF ENVIRONMENTAL QUALITY 3

CONNECTICUT DEPARTMENT OF ENVIRONMENTAL PROTECTION STATE OFFICE BUILDING f . HARTFORD, CONNECTICUT 06115 NPDES PERMIT Northeast Nuclear Energy Company P.O. Box 270 Hartford, Connecticut 06101 Attention: Mr. R. A. Reckert Vice President Re: DEP/WPC-152-003 Town of Waterford Long Island Sound Watershed Gentlemen:

This permit is issued in accordance with Section 22a-430 of Chapter 446k, Connecticut General Statutes and Section 402(b), Federal Water Pollution Control Act, as amended 33 USC 1251, et. seg., and pursuant to an approval dated September 26, 1983, by the Administrator of the United States Environmental Protection Agency for the State of Connecticut to administer a Natural Pollutant Discharge Elimination System (hereinafter " NPDES")

.\s permit program.

The discharge is subject to the effluent guidelines and standards for the steam electric power generating point source category promulgated on November 19, 1982 pursuantEto Section 301 of'the Federal Clean Water Act, as amended. Specifically, this discharge is~ subject to 40 CFR Parts 125 and 423 of'the effluent guidelines and standards.

The Commissioner of Environmental Protection (hereinafter "the Commissioner")

has determined that the effluent limitations which would require the use of cooling systems at the Millstone Nuclear Power Station, Units 1, 2 and 3 other than the once-through system proposed by the applicant for the control of the thermal component of the applicant's discharge are more stringent than necessary to assure the protection and propogation of a balanced

' indigenous population of shellfish, fish and wildlife in and on the receiving waters. In view of this find, the Commissioner has herein established alternative and less stringent effluent limitations in accordance with Section 316(a) of the Clean Water Act.

However, the Commissioner has also determined that additional evidence based upon actual operating experience of Millstone Nuclear Power Station, Units 1 2 and 3 would be desirable in order to corroborate'the Commissioner's findings.

The Commissioner expressly reserve the right to impose more stringent effluent i limitations with respect to the. thermal component of the Company's discharge l pursuant to Section 22a-430 of Chapter 446k, Connecticut General Statutes

! should further investigation of the effect of the Company's discharge' fail to corroborate the Commissioner's determination that more stringent effluent i

I

. .. . . ~ _ . . . . - .. _ . - - . - - _ - _ - , - - _ - _ . - _ -

e .

, 2- June 5, 1985 l,

} limitations are not necessary to assure the protection and propagation of a balanced indigenous population of the shellfish, fish and wildlife in and on the receiving waters.

The Commissioner has determined that the location, design, construction and capacity of the cooling water intake structure represents the best available technology for minimizing adverse environmental impact from impingement and entrainment pursuant to Section 316(b) of the Federal Act. The Commissioner has also determined that additional evidence based upon actual operating experience of Millstone Nuclear Power Station, Units 1, 2 and 3 would be desirable in order to corroborate the Commissioner's findings.

[ Such data would be generated by the studies to be conducted pursuant to paragraphs 5 and 12 of this permit. The Commissioner further finds in this

instance that no such determination is necessary at this time to carry out

{ the purposes of the Federal Act pursuant to Section 402(a)(1) thereof.

l The Company should take cognizance of the fact that additional evidence

! may result in the imposition of more stringent effluent limitations requiring the potential utilization of a cooling system other than one j proposed. Accordingly, the company should take this potential into consideration in their design wherever feasible.

l The Commissioner has found that the systems installed for the treatment of

. the nonthermal. discharges will protect the waters of the state from pollution.

This action is further found to be consistent with the applicable policies

! of the Connecticut Coastal Management Act (Section 22a-92 of the Connecticut

{ General Statutes, as amended by Section 2 of Public Act 79-535).

i The Commissioner has determined in the absence of any applicable effluent j stadards or limitations issued or approved under the Clean Water Act that the treatment facilities for nonthermal discharges constitute best available r technology economically achievable using the standard of best professional I

judgment.

The Commissioner hereby finds that the Northeast Nuclear Energy Company is maintaining a facility known as Millstone Nuclear Power Station, described in the reapplication package dated November 15, 1984.

I The Commissioner, acting under Section 22a-430 hereby permits Northeast l Nuclear Engery Company, Millstone Nuclear Power Station, to take such i action as is necessary to:

1) Insure that all wastewaters generated by the activities of the Northeast Nuclear Energy Company, Millstone Nuclear Power Station Units Nos. 1 and 2, described in the above-referenced reapplication are collected,

The discharge of any pollutants _other than those so authorized, or the discharge of any other pollutant, in quantities or concentrations which have or may have an adverse impact on the receiving waters, or which is not in accordance with the maintenance of best management practices for industrial chemicals at the facility is prohibited.

5) The permittee shall conduct or continue to conduct biological studies of the supplying and receiving waters, entrainment studies, and intake impingment monitoring. The studies shall include studies of intertidal and subtidal benthic communities, finfish communities, and entrained plankton and shall include detailed studies of lobster populations and winter flounder populations.

6) Monitor and record the following for the purpose of reporting quality and quantity of each discharge according to the following schedule:

(Refer to individual Discharge Serial Number for Surveillance Requirements)
