, 1.0 Introduction ,

. Appendix B.to the operating license for the Shoreham Nuclear Power Station (SNPS) is entitled Environmental Protection

~

Plan (Non-Radiological) . This docament requires the submis-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-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, 1987 to December 31, 1987. During this period, Shoreham's operating license remained re-stricted to 5% power and the effect of SNPS on the y environment was negligible.

6.0 Summary of environmental protection activities required by EPP Section 4.2 6.1 Groundwater well monitoring As required by the EPP, an NRC approved groundwater well monitoring program has been established at the Shoreham Station. The program is intended to demon-strate that 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. Presently, reporting is not required. However, if unusual or adverse effects are noted, a repcrt shall be issued pursuant to EPP Section 4.1 (Unusual or Important Environmental Events).

Although not yet required by the EPP, which calls for the program to commence at the initiation of testing above 5% power, LILCO began sampling in 1987 to establish basaline water levels and chloride content.

6.2 Prot ; tion of Wading River Marsh

  • rot . ion of Wading River Marsh, particularly from dri ting 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 march were threatrned by buildup of a sandbar at the creek mouth until it was dredged by the Town of Riverhead in October 1987 (see Section 6.3).

Aside from the protections offered by thin 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 permite from NYSDEC. There is no routine reporting requirement for this iten.

6.3 Beach erosion monitoring and replenishment Section 4.2.3 of the EPP requires monitoring of beach sand accumulation 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 accumu-lated sand dredged from the plant intake or from the mouth of Wading River Creek. Monitoring, maintenance

dredging and beach replenishment are also required to meet conditions of-New York State Water Quality Certification issued by the New York State Department of Environmental Conservation. 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 or 1987 because the New York State Department of State (DOS) declined to concur with LILCO's certification that the proposed dredging was consistent 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 expirca in 1985. At the end of 1987 this matter was still in litigation.

As LILCO has been refused permits to perform maintenance dredging since 1985, the mouth of Wading River Creek became increasingly blocked with an accumulation of sand. This restricted water access to the Town of Riverhead's small beat launching ramp located a short distance up the creek. After receiving a number of complaints from local boat owners, the Town applied for and received an Aruy Corps permit to dredge the creek and performed maintenance dredging in the mouth of the creek in October 1987. However, the amount dredged was only sufficient to allow passage of small boats and did not begin to approach the amount needed to fully remove the amount of sand accreted since the last major dredging in 1985.

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.
