I.

Continuous Monitoring of Oceanographic Parameters from Fixed Points:

A.

Mooring Deployment: More than 30 different specially designed mooring systems to serve as instrumentation platforms have been deployed on a year-round basis.

B.

Current Measurements:

For nearly 7 years continuous water current speed and direction measurements have been obtained from the various offshore moorings compiling a data base, exceeding 40 current-meter mooring years.

C.

Temperature Measurements:

For nearly 7 years continuous water temparature measurements have been obtained from the various of fshore moorings as well as from around the Inner and Outer Sunk Rocks and the Hampton Harbor estuary, documenting nearly 30 temperature monitoring years of data.

D.

Tide Elevation Measurements:

For 6 years tide clevation was monitored continuously in the Hampton Harbor estuary.

4 II.

Oceanographic Cruises:

A.

Plankton Cruises:

Essentially monthly oceanographic cruises to survey plankton distribution, hydrographic parameters, and net circulation patterns (drifter releases) in the western gulf of Maine out to almost 25 n mi offshore.

B.

Slack Water Surveys: Monthly to semi-monthly hydrographic surveys to document low water and high water " slack" distributions of ambient temperature, salinity, density and dissolved oxygen at stations in Hampton Harbor and offshore around the various proposed intake and discharge sites.

C.

Special Temperature Studies: Over a 1 year period intensive temperature surveys (including irl situ monitoring and tide pool measurements) were made around the Inner and Outer Sunk Rocks off the mouth of Hampton Harbor.

SB 1 & 2 ER-OLS O

TABLE 6.1-1 a

(Sheet 2 of 2)

III. Anchor Station Studies:

Periodic surveys over a tidal cycle at selected stations to document ambient currents, temperature, salinity, density and dissolved oxygen; frequently included iil situ streamer observations and drogue studies.

IV.

Drifter Studies:

More than 4 years of drif ter releases including some 12,000 drif t bottles and nearly 15,000 drogue and sea-bed drifters with an overall recovery of about 25 to 40%, depending upon the drif ter type; included a special study to determine the probability of coastal waters entering the Hampton Harbor estuary and neighboring estuaries as a function of distance and depth offshore.

V.

Sedimentological Studies:

t A.

Sediment Stakes: Monthly height measurements of stakes jetted into the sea floor were used to document long-term, net-sediment erosion and/or deposition.

B.

Sediment Trap: This device was used to document seasonal aspects of near-bottom suspended sediment transport at the nearshore intake site; C.

Turbidity Survey:

Two special surveys were conducted to measure ambient turbidity levela in Hampton Harbor estuary under " typical" and " post-storm" conditions.

described in Section 3.4.5 (pages 3-9 and 3-10) of the FES-CP.

Control of fouling within the condenser system was to be by low-level chlorination injection at the pumps. The OL stage ER reaffirmed the intent to use this method of biofouling control, in Section 3.4.2.5 (ER page 3.4-2).

In response to NRC IE Bulletin 81-03 (on safety related problems resulting from biofouling), the applicant stated (in his letter of July 8,1981) that thermal treat-ment of the main circulating water and low level chlorination for service water systems would be used.

During the site visit, we learned that the applicant has revised his plans for biofouling control and now proposes to use continuous chlorination, with injection at the offshore intake. To this end, a chlorine-injection pipeline is being constructed within the concrete ifning of the 17,000 foot intake tunnel. With this system, chlorine injection would be used to control fouling of the entire once-through cooling system.

The applicant proposes to use this method because it does not require a reduction in station load, as does the thermal backflushing method.

The applicant has discussed this new proposa] to chlorinate continuously with the NH Water Supply and Pollution Control Commission.

At this time, the Commission has not been requested to approve the proposal, but has stated that the applicant could construct ~ the necessary equipment (i.e.' pipeline, etc.) with the understanding that it may or may not be -approved for operational use. The thermal backflushing option, therefore, still is a viable option.

Discussions with State of New Hampshire agencies during the site visit revealed that they are cc,cerned with the potential impacts of continuous chlorination to Gulf of Maine aquatic biota. The USEPA also is concerned, since with this method, Seabrook might discharge more chlorine into the environment than any other power plant now operating.

We will provide you with some questions for formal submittal to the applicant prior to addressing this issue in the DES.

Lastly, you should note that the eventual control method for biofouling might be different from that provided by the applicant in his response to the IE Bulletin.

The appropriate IE person should be informed.

B.

The staff (M. Kaltman and G. Gears) toured sections of the proposed Seabrook/Scobie Pond and Seabrook/Tewksbury transmission lines.

Issues involving historic preservation and human health and safety were raised during the staff's field investigations of the proposed transmission system as well as during the public scoping meeting.

Interaaency Coordination A.

The NPDES permit for operation of Seabrook Station has not yet been issued by the USEPA.

Due to a desire by both HRC and EPA to perform our operational environmental reviews in concert, the EPA has agreed to accelerate the NF0ES process to coincide with the DES. A draft NPDES permit will be prepared by EPA and ready for inclusion into the DES by March 1,1982.

This review-in-concert is a critical element of this DES, thus some parts of our input will have to await receipt of the draft permit.

The March 1, 1982 deadline for DES input to the LPM, therefore, might not be met for some sections of the aquatic ecology / water quality reviews.

B.

The USEPA also desires to be a party in the preparation of the DES.

By mutual agreement, this will be accomplished by EPA reviewing the NRC staff input prior to publication of the DES.

This will require staff input to be fonvarded to EPA (Boston, MA),

reviewed critically by EPA staff and returned. We then will review the EPA comments and revise the input as appropriate, prior to submitting our final DES input to the LPM. Achievement of this coordination and inclusion of the information on the NPDES permit in the DES will result in a unified interagency position on Seabrook - with respect to impact projection and operational monitoring (required by the permit). One of the chief concerns of the NH Fish and Game Department will be an adequate program to monitor the operational impacts resulting from fish impingement and ichthyoplankton entrainment.

Proper coordination concerning the NPDES will ensure that these concerns are adequately reflected in the DES.

C.

During the interagency meeting at the site visit, we made an initial contact with the U.S. Fish and Wildlife Service (FWS),

as a precursor to formal communication required by the Fish and Wildlife Coordination Act of 1958. To initiate the formal participation of the FWS in our EIS process,for Seabrook, we prepared a letter for your signature (with concurrence by the LPM) to the FWS Supervisor of Ecological Services, Concord, NH.

This will enable FWS to provide to NRC their concerns relative to Seabrook, prior to DES publication.

New Issues for Treatment in the DES A.

One of the concerns during the CP stage environmental review was the impact to aq' atic biota resulting from thermal backflushing, u

an operation designed to control biofouling of the intake tunnel and offshore structures.

The thermal backflushing operation is
