1. IntroduttiqD This report describes the implementation of the Environmental Protection Plan (EPP) from January 1, 1991 through December 31, 1991.

Provided herein are summarios and results of tne environmental protection activities required :2y Subsection 4.2 of the EPP.

2.0 Environmental Protectlpn Activitlen 2.1 &quatic MonitoriDS The Environmental Protection Plan states that the NRC will rely on decisions made by the Commonwealth of Pennsylvania, under the authority of the Clean Water Act, for any requirements for aquatic monitoring. Industrial waste NPDES Permit PA 0051926, dated September 19, 1984, provides the mechanism for protecting water quality and indirectly aquatic biota.

In accordance with the requirements of Section 3 of the Permit, monitoring results were summarized for each month and reported on Diccharge Monitoring reports (DMR) which were submitted to the DER and EPA.

~

A summary of the resulta as reported in the monthly DMR's is on Table 1. In addition, studies of corbicula and Zebra mussels, fish impingement on the Schuylkill River intake screens, and water quality sampling and observations at still Creek and Owl Creek Reservoirs were performed in support of LGS in 1991.

Periodic _ inspections.of the Still Croek and Owl Creek reservoirs and receiving streams revealed no sign of increased erosion, sedimentation, or other environmental damage.

The survey-for corbicula and Zebra mussels covered

.many locations in the Point P'.easant Water Diversion-System, the Schuylkill-River-and--Blue Marsh Lake._ No Zebra mussels were found, but the

, range of corbicula in LGS source waters continued

to expanded over the areas previously known.

I Living corbicula and/or_ shells were found in l

Bradshaw Reservoir, nany locations in the Fehuylkill- River including the vicinity of the LCS 1

- intake, Blue Marsh Lake, the Point Pleasant Pumping Station, the Perkiomen Creek and the East Branch Perkiomen Creek.

The Schuylkill River near LGS was occasionally electrofished to obtain Radiological Environmental Monitoring Programs samples and as part of the Environmental Education program. Biologists observed production of an exceptionally largo year class of carp and goldfish correlated with low, sta"le river flow in the spring and summer.

2.2 Terrectriql MonitoriDS Ho terrestrial monitoring is required, 2.3 Maintenance of Trangnission Line Corridgni Transmission line maintenance records concerning herbicide use are being maintained by the Company's Electric Transmission and Distribution Department. As required'by the EPP, these records can be made available to the NRC upon request.

2.4 N_olse Monit9IiD All noise surveys required by the LGS Final l Environmental Statement,-Section 5.14.4, Atomic

! Safety Licensing Board (ASLB) culing LBP-83-11, dated-March 8, 1983, and LCS Appendix B Technical o Specifications, Sections'2.3 and 4.2.4. were completed in 1990 for Limerick Generating Station Unit 2 operation-and Bradshaw Reservoir. Theso  ;

studies were reported on in the 1990 Annual l Environmental Operating' Report (Non-radiclogical).

2.5 Environmental Plotection Plan There were two Environmental Protection Plan -(EPP) noncompliances identified by the-1991 EPP Audit by the Nuclear Quality. Assurance Department.

a. Corrective Action-Request (CAR), Q0001904, identified a failure to provide notification

• to the NRC of proposed.and approved changes y to the NPDES permits within the interval required by the EPP. A Common Nuclear Procedure identifying responsibilities and l 2 n

.. overall programmatic controls is being developed.

b. Corrective Action Request, Q0001905, identificu a failure to obtain the required number of samples to determine the amount of free available chlorine present from sampling location 001. The CAR was issued closed because corrective actions to prevent a  ;

recurrence were agreed upon and verified to have been completed prior to the conclusion of the audit. <

2.6 Changes in Station Desian on Operatton, Tests gr ExperimqDLR There were no changes in the Limerick Generating Station operation that required an Environmental '

Evaluation in accordance with the requirements of Section 3.1 of the Environmental Protection Plan.

2.7 ILQp-routine Reports Submitted Ten non-routine reports were submitted in accordance with EPP Subacction 5.4.2. Copies of all letters were supplied to the NRC.

4. NPDES violations for discharge temperature from Bradshaw Reservoir occurred on July 7, 1991, July 19, 1991 and July 26,1991 due to electrical storm induced loss of power and on July 21, 1991, July 23, 1991 and July 25, 1991 due to extreme ambient conditions. The Bucks County Department of Ilealth was notified by telephone in accordance with NPDES permit requirements for each occurrence. The 5-day reporting requirement was waived by the Department.
