1986 ANNUAL ENVIRONMENTAL OPERATING REPORT Shoreham Nuclear Power Station 1.0 Introduction l Appendix B to the operating license for the Shoreham Nuclear l Power Station (SNPS) is entitled Environmental Protection l

Plan (Non-Radiological). This document requires the submis-l sion of an Annual Environmental Operating Report prior to May 1 each year for the previous calendar year. The report which follows is submitted in fulfillment of this require-I ment. It documents implementation of the Environmental Protection Plan (EPP) and addresses all study, recording and reporting requirements of the plan.

The period covered in this Annual Environmental Operating Report is from January 1, 1986 to December 31, 1986. Shore-ham's 5% power retest program commenced and the mode switch i was placed in the startup mode twice, April 17 and August 3, 1986. On the former date, a leak was detected in the main j

condenser tube sheets and the unit was placed in shutdown.

The latter startup period proceeded until August 30. During this 27 day period, a milestone occurred when the plant's main generator was synchronized with the grid system and l

Shoreham generated approximately 19 megawatts of electricity i

for a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. During 1986, the effect of SNPS on the environment was negligible.

l 2.0 EPP Non-compliances (Section 5.4.1 of EPP)

On June 2, 1986, a copy of Shoreham Nuclear Power Station's SPDES (State Pollutant Discharge Elimination System) Permit renewal application was not submitted to the NRC as prescribed in Section 3.2 of Appendix B to' Operating License NPF-36. This was discovered by SNPS Licensing on October 9, l 1986 at 1600 hours0.0185 days <br />0.444 hours <br />0.00265 weeks <br />6.088e-4 months <br />. A copy of SNPS SPDES Permit renewal application was then submitted to the NRC along with LER 86-042 which described the event. A review of other similar license requirements has since taken place. This review and a procedure change was made to preclude a similar i occurrence.

None 5.0 List of State Pollutant Discharge Elimination System (SPDES) permit related reports sent to the New York State Department of Environmental Conservation (NYSDEC) relating to matters in EPP Section 2.1 (Section 5.4.1 of EPP) 5.1 Aquatic monitoring - thermal effects None 5.2 Aquatic monitoring - intake related effects None 6.0 Summary of environmental protection activities required by EPP Section 4.2 6.1 Groundwater well monitoring The EPP requires a groundwater well monitoring program be established, commencing at the initiation of testing above 5% power and running for 2 years. The EPP also required that the program plan be approved by the NRC prior to implementation. The NRC formally approved the plan March 14, 1986. No routine reporting is required unless unforeseen effects are noted, in which case a report shall be issued pursuant to EPP Section 4.1 (Unusual or Important Environmental Events).

The Groundwater Monitoring Program for the Shoreham Nuclear Power Station is intended to demonstrate that l

extraction of groundwater from station supply wells

, for plant operation does not adversely impact offsite private water supplies either due to excessive drawdown or saltwater intrusion.

To implement the program, three monitoring wells and a control well were established in early 1986, as de-scribed in LILCO correspondence to the NRC (SNRC-1124, SNRC-1162, and SNRC-1224). The monitoring wells are located approximately 400 feet to the south-southwest (M-1), 900 feet to the south (M-2), and 2100 feet to the north (M-3) of the station wells. The control well (C-1) is 1500 feet to the southwest of the station wells. The monitoring well to the north will monitor the private offsite downgradient wells located at the north side of Wading River, approximately 2100

ATTACHMENT SNRC-1333 Page 3 feet-north of the supply wells. The other monitoring wells will indicate changes in groundwater level and chloride content before upgradient wells are affected.

Although not required by regulation, LILCO expects to sample and establish baseline water levels and chloride content in 1987.

6.2 Protection of Wading River Marsh Protection of Wading River Marsh, particularly from drifting sand, was of concern during construction of the plant. The construction permit directed LILCO to protect the marsh from drifting sand through use of ground cover, other vegetation and administrative action. Now that construction has ended, the potential for adverse effects from construction has diminished. However, flushing rates of the marsh are being threatened by buildup of a sand bar at the creek mouth (see Section 6.3).

Aside from the protections offered by this EPP, the Wading River Marsh is protected through New York State wetlands laws and regulations; any activities that might affect the Marsh in any way cannot be conducted without permission and permits from NYSDEC. There is no routine reporting requirement for this item.

6.3 Beach erosion monitoring and replenishment Section 4.2.3 of the EPP requires monitoring of sand accumulations and/or erosion in the vicinity of the plant site. Any beach material eroded from east of the plant's jetties is to be replaced with accumulated sand dredged from the plant intake canal or from the mouth of Wading River Creek. Monitoring, maintenance dredging and beach replenishment are also required to meet conditions of the Shoreham Technical Specifica-tions and the State Water Quality Certification issued by the Department of Environmental Conservation and agreements with the local community. The work is generally conducted annually in the spring to clean the intake canal and the mouth of Wading River Creek of sand that has accumulated since the previous dredging. These activities are carried out under dredging and wetlands permits issued by the U.S. Army Corps of Engineers and New York State Department of Environmental Conservation.

Maintenance dredging and beach replenishment was not conducted in 1986 because the New York State Depart-

c:

. ATTACHMENT SNRC-1333 Page 4 ment of-State (DOS) declined-to concur with LILCO's certification that the proposed dredging was consis-tent with New York's Coastal Management Program. DOS approval is required for the Army Corps of Engineers to issue the required maintenance permit to dredge.

This information was provided to NRC Region I via Special Report 86-011, Revisions 1 and 2, in accordance with Technical Specification 3.7.1.4.b.

The previous ten year permit expired in 1985. The matter is presently in litigation.

6.4 Herbicide usage Section 4.2.4 of the EPP requires that records be maintained of any herbicides utilized on the plant's transmission line rights-of-way. These records, which are also required to be kept for review by NYSDEC for a period of 3 years, are maintained in the appropriate Divisional Offices at LILCO. There is no routine reporting associated with this item.
