A n s w or waste water treatment plants have resulted in the discharge-of pollution to the environment.
The effect has been the closing of importart shellfish beds within the region due to elevated fecal
-coliform bacteria within the resource.
Seabrook Station operates its own wastewater treatment facility onsite, in full compliance with the NPDES permit.
Seabrook Station is not-a known contr;buting agent to this pollution source. Additionally, the Town of Seabrook will in the 8
3 near future be building a wastewater treatment facility for its residents which will eliminate numerous private septic systems which are expected pollution sources.
No large industry of other power plants are located within the vicinity of Seabrook Station.

Q.
Provide a copy of your Section 316(a) and (b) Demonstration Report required by the Clean Waste Act.
What Section 316(a) and (b) determinations have been made by the regulatory authorities?
A.
Licensing for Seabrook Station began in February 1972, with an application before the New Hampshire Public Utilities Commission (PUC) for a Certificate of Site and Facility. An application for Construc-tion and Operating License was tended by Public Service Company of New Hampshire (PSNH) to the Atomic Energy Commission (AEC) in March 1973.
The New Hampshire PUC issued a Site and Facility Certificate in January 1974 and_the AEC issued a draft Environmental Statement in April 1974.
An appl 4ation for a waiver to section 316 of the Federal Water Pollution control Act for a once-through cooling water system was filed by PSNH in August 1974.
The NRC staff issued the Final Environmental Impact Statement in December 1974 which :eflected views and comments by the public, the Council of Environmental Quality, as well as Federal, State and local agencies, including the EPA.
Public hearings were held by EPA on PSNH;s requested exem)tions from thermal effluent limitations and on design criteria for t1e intake of the proposed once-through cooling water system under Sections 316(a) and 316(b) of the Federal Water Pollution Control Act. The Seabrook proceedings were the first under Section 316(b) for intakes. Numerous Determinations were made by the EPA from 1975 to 1977 based upon information obtained at public hearings and documents supplied by PSNU.
In June of 1977, the EPA Administrator issued a decision reversing an earlier decision-by the Regional Administrator in November of 1976.
In his decision, the Administrator affirmed the RA's initial finding l
that the plant's intake and discharge tunnels represented the best technology available in design and location of the cooling water sp tem.
In addition, that the adult Mya (clam) population would not be significantly reduced by larvae deaths caused by heat.
This decision is attached for reference.

Also attached is a summary document prepared by environmental consultant, Normandeau Associates.
(Enclosure 2) The document summarizes all pertinent work that was accomplished up to December 1977 with respect to assessment of possible impacts on the marine ecosystem of the construction and operation of Seabrook Station.
