:RELATED TO DPERATION OF PILGRIM STATION UNIT 1 NPDES PERMIT PROGRAMS In accordance with NPDES-Permit requirements for Pilgrim Station Permit No.
MA0003557 (Federal)-and No. :359 (State), the following modified programs are presented for-1991. The 1978 through 1990 programs were submitted to-the Regional Administrator, U.S. Environmental Protection Agency (EPA) and Director, Mass. Division.of Hater Pollution Control (MDHPC), in December 1977 through December 1989, respectively.
* I. ENVIRONMENTAL MONITORING The Environmental Monitoring Program represents a continuation of                       -i previous monitoring. Pre-operational studies for Pilgrim Unit l' commenced in 1969, almost four years before initial operation in December 1972. In accordance with environmental monitoring and
                                     -reporting requirements of: the Unit 1 Operating License, DPR-35, issued by the U.S. Atomic Energy Commission.(now the Nuclear Regulatory Coarnission)-Boston Edison carried out a post-operational Marine Ecology Program. _ This program was designed to investigate the                    ,
Cape Cod Bay ecosystem, with emphasis on the Rocky.-Point area, in order to determine whether the operation'of Pilgrim Station resulted in measurable effects on the marine ecology and evaluate the                              E significance of any such. effects. .The Marine Ecology Program for Unit 1 continued _for five years from initial full power operation (that is, through December 1997) and was replaced by.this NPDES Permit = Program (with-NRC concurrence). Amendment #67 (1983) to the PHPS-Technical-Specifications deleted Appendix-B non-radiological                         r water quality requirements since the NRC believed they were incorporated in.the. NPDES Permit. The post-operational monitoring for Pilgrim Unit 1-and the collected data are incorporated and                           i analyzed in-the Marine Ecology Semi-Annual Reports.(#1-36), Marine Ecology Finaln Report -(1978), and the Section 316 Demonstration -                      o

The Division of Marine Fisheries (DMF), an agency of the                           i Commonwealth ~ of Massachusetts, conducts field monitoring pertinent to Pilgrim Station.       The monitoring efforts listed
                                        -below will-be continued in~ 1991, fhh -
The DMF monitors-the occurrence and-distribution' of fish around Rocky Point and at-sites in the-area of discharge temperature increase. Groundfish will be collected using a 32 foot Shrimp                     ,

ALfinfish observational dive survey (Figure 2) will continue _ in 1991 for the Pilgrim: Station thermal plume' area. This monitoring will involve bi-weekly diving from May through November to                         -
document fish behavior and condition at six stations. During (mid-August to mid-September, weekly diving will be done to document potential thermal plume-related mortalities. A cunner tagging effort will.be commenced to: determine this resident-species-relation to the thermal. plume.
                                                                                                                        +

In June-November 1991,-a'150-foot beach seine-(3/16 inch mesh bag) ' survey-(Figure 1) will be performed bi-weekly at four:-
stations, including:one in the Pilgrim Station-it.dke embayment.

                             ''An experimental lobster pot study, initiated in 1986, will be continued during June-September.in reference and surveillance areas to better define Pilgrim _ Station's thermal influence ~on lobster-catch rate (Figure 3).
The DMF has collected lobster catch statistics bi-weekly through each fishing season (May-November) by sampling commercial lobstermen's pot hauls. This effort will continue with one                       ,
lobsterman as a measure of the Pilgrim Station effect on the local' lobster population (Figure 4 shows the sampling grid).
Gas' Saturation-In 1991,. saturated gas analyses will be conducted only during periods-of potential discharge-related mortalities. A Heiss saturometer will- be.used in situ to measure total partial                       '
pressure of dissolved gases, and percent saturation of total gas, nitrogen, and_ oxygen.

E. .Entrainment Monitorino (Marine Research, Inc.)-
1 As-in 1990,- entrainment monitoring in 1991 will emphasize consideration of ichthyoplankton.
The 1991 entrainment studies will consist of routine monitoring of the Pilgrim discharge. .This _ monitoring will be on a _ weekly basis during the period March-September and bi-weekly during the periods January-February and October-December. Samples will be collected in triplicate.      If exceptionally high egg or larvae concentrations are found in the discharge when compared with previous years, steps will be taken to implement contingency ichthyoplankton sampling plans to assess the reason for the high concentrations. The first plan will consist of additional tows and sample. analysis from the discharge canal. If ichthyoplankton numbers = remain exceptionally high, the second plan consisting of single tows at each of 13 Bay stations off the plant will be initiated, and the samples analyzed immediately to determine the-cause for the high densities (Figure 5). HRI will analyze the data and prepare the reports.
F. Reoortino of Environmental Monitorino Semi-annual and annual reports with results of the above (Items A-E) will be submitted to the EPA and HDHPC on October 31, 1991 and April 30, 1992 covering the periods January-June and January-December 1991, respectively.
II. THERHAL DISCHARGE FISH SURVEILLANCE                                                 ,
The Thermal Discharge Fish Surveillance Program for Pilgrim Station
                    -has'the following primary parts:
A,    Onrf_lichts Periodic aerial overflights of western Cape Cod Bay and the Pilgrim vicinity-will'be. conducted- to alert Boston. Edison to the -
presence of large schools of fis_h in the area. - These overflights
                          .:will be-conducted weekly-from March-November 1991 and results-summarized by BECo in;each annual monitoring. report.
B. Discharoe Insoections -
Frequent visual inspections of the discharge canal and fish barrier netiduring periods of fish migration will determine fish presence and condition, and barrier net performance. Also, fish sampling and diver observation in the plume area will be.
conducted bi-weekly from May through-November by Massachusetts Division of Marine Fisheries personnel as part of the Environmental:Honitoring Program.

                                               -The observation and inspection elements of the Surveillance l Program monitor compliance with the NPDES Permit barrier net condition, by providing a check on the adequacy of_ the net in preventing fish passage into the discharge canal. If these
                                               -elements indicate that the barrier net is not functioning adequately, overflights, as well as the canal inspections and dive. observations, will indicate when fish susceptible to gas bubble. disease mortality are sufficiently near Pilgrim-Station to warrant action to reduce surface nitrogen saturation level to less than 115%. In addition, Boston Edison will notify the EPA Regional Administrator and Massachusetts DWPC Director of the presence of large schools of fish within 1/2 mile of the                      ;
discharge canal.                                                              '
III. DISSOLVED NITROGEN SATURATION REDUCTION The plan for reducing. dissolved nitrogen surface saturation levels to less that 115% in-the discharge canal will involve a power reduction or outage should a school of fist susceptible to gas bubble disease mortality be in the immediate vic'nity of Pilgrim Station. The procedure-for determining the neeil, feasibility and request for a power reduction or_ outage is as follows:
A.      Responsible regulatory / agency personnel familiar with fishery statistics (e.g. Mass. Divisian of Marine Fisheries) will estimate the' magnitude of the fish school and, based on measured water quality and other pertinent environmental data, make a determination as to the likelihood and effect of a gas bubble disease mortality. -They will also determine the potential
                                                 . necessity for a nitrogen saturation reduction, and notify Boston Edison of this initial judgment'.
: 8.      Boston Edison will notify the Rhode Island, Eastern Massachusetts, and Vermont Energy Control (REHVEC) of the possibility of a power reduction and obtain. projections through at least the upcoming weekend. Boston Edison will transmit load information to the agencies / persons taking the-actions identified in action A above.
C.      On the basis of this information, agency personnel will formulate specific recommendations to the EPA Regional Administrator and/or the HDHPC~ Director on the timing and duration of a power reduction 'that is, in their judgment, appropriate and in the overall.public: Interest.
                                                                                                                ~
D.       Responsible regulatory personnel will request a power reduction through a telephone call to-the Boston Edison,' Pilgrim Nuclear Power-Station Director.
E.    -Boston' Edison personnel will record results of periodic-                    >
surveillance of the condition and location of the fish prior to and subsequent to any~ Station operational changes.
