b 1.O INTRODUCTION This report describes. the implementation of the Enviromental Protection Plan (EPP) from January 1,1985 through Decenter 31, 1985.

' Provided herein are stmmaries and results of the environmental protection activities required by Subsection 4.2 of the EPP.

2.0 ENVIR0 MENTAL PROTECTION ACTIVITIES 2.1 Aquatic Monitoring The Environmental Protection Plan states that the NRC will rely on decisions made by the Conmonwealth of Pennsylvania, under the authority of the Clean Water Act, for any requirements for aquatic monitoring.

Industrial Waste NPDES Permit PA 0051926 dated Septenter 19, 1984 provides the mechanisms for protecting water quality and indirectly aquatic blota.

1 In accordance with the requirements of Section 3 of the Permit, b nonitoring results were somnarized for each month and reported on Discharge Monitoring Reports which were submitted to the DER and EPA.

. 2.2 Terrestrial Monitoring No terrestrial monitoring is required.

2.3 Malntenance of Transmission Line Corridors Transmission line maintenance records concerning herbicide use are

, being maintained by the Comany's Electric Transmission and Distribution Department. As reautred by the EPP, these records can be made available to the NRC upon request.

2.4 Noise Monitoring Noise surveys were conducted at the Limerick site to quantify the seasonal defollated and foliated baseline anblent noise levels. The ten sarmling locations shown in Figure 5.7 of the Final Environmental Statement and used for the Bechtel 1973 anblent noise survey were also used for this survey. Four additional sarmling locations were chosen to characterize additional industrial noise sources in the environs as I

well as to account for sensitive receptors with an elevated

, topographical line-of-sight to the Limerick Station.

locat b,s M ,re M talM d for the defoliated season. Two of these locations were dropped frcm the foliated survey because one has a significant terrain barrier shleiding the location from the Limerick Station and the other's noise environment is dominated by vehicular traffic on nearby Route 422. Residual 1/3 octave band baseline 'anblent noise levels were also measured.

3 These noise sampling locations will be resurveyed for Limerick Generating Station one unit nonnal operation and for two unit normal operation.

Since construction of the supplemental cooling water system is

- Incomplete, no sound survey was made at Point Pleasant or Bradshaw.

2.5 EPP NonecrrelIances There were no EPP-noncompilances for this reporting period.

2.6 Chances in Station Design or Operation, Tests, or Experiments Environmental Evaluations were performed for the below IIsted changes in the Limerick Generating Station operation. In accordance with the requirements of Section 3.1 of the Environmental Protection Plan, each listed change includes a brief description, analyses, interpretation and evaluation.

1. Substitution for 1985 of instream monitoring of dissolved oxygen levels in the Schuylkill River in place of the 59 constraint on consumtive water withdraws (DRBC Docket No. D-69-210LP). DRBC's decision to Ilmit Schuylkill River withdrawals was intended to reduce stresses on the Schuylkill River when water quality is significantly affected by organic waste assimilation. When temperatures in the river exceed 59"F, the biological oxygen demand accelerates and the dissolved oxygen necessary for waste assimilation beccrnes critical .

Authorization by the DRBC of dissolved oxygen monitoring assured continued protection by direct measurement of the Schuylkill

. River during critical periods. Dissolved oxygen was monitored at j critical locations at least six times a day above and within 200 j feet of each of the six dams on the Schuylkill River located below the Limerick intake.

In addition, the dissolved oxygen monitors provided data, not otherwise available to the water resource agencies, for better management of the Schuylkill River.

2. For 1985, consunptive water allocations not used by Titus Generating Station, Units 1, 2 and 3 and Crcmby Generating Station Unit 2 may be used by Limerick Generating Station, Unit I when existing flow and dissolved oxygen constraints would otherwise prohibit withdrawal.

4 Together, Crorby Unit 2 and Titus Units 1, 2, and 3 were auth arized to use Schuylkill water for constrnptive use equivalent to a maximum withdrawal of 5.2 mgd. Of the 5.2 mgd constmptive use suthorization that PECo requested 3.5 mgd was from the Titus un i' s . Limerick is approximately 23 miles downstream of Titus.

_ The5, the Schuylkill River was enhanced for a 23 mile reach due to the delay in constriptive use of 3.5 mgd. The remaining 1.7 mgd was obtained from the Cronty allocation. An adverse imoact on the

., 9 mile reach below Limerick to Crcrity Station would be expected due to the earlier constsrptive use of water. However, because a longer reach of the river was benefited by a larger quantity of water, the net environmental inpact although inmeasurably small, was positive.

3. In order to allow completion of the Limerick Generating Station test program, the DRBC on October 2, 1985 granted an emergency certificate which changed the flow restraints for constmptive use of the Schuylkill River frcm 530 cfs to 415 cfs.

The DRBC previous approval of a 530 cfs flow limitation on Schuylkill River water withdrawal was intended to maintain river water quality primarily by limiting total dissolved sollds (TDS) to 455 mg/l Just below the LGS discharge pipe for 1 unit operation (480 mg/l for 2 unit operation). Because of recent improvements In the background TDS level in the Schuylkill River, the new flow target of 415 cfs can maintain TDS below the 455 mg/l value previously considered acceptable by the DRBC. As Insurance that this TDS value was not exceeded, the emergency certificate required PECo to monitor the background TDS level and to cease water withdrawal when the level exceeded 425 ppm and the flow was between 415 cfs and 530 cfs.

i; These three changes in operational activities did not involve either:

3 1) a matter which may result in a significant increase in any adverse envirorrnental impact previously evaluated in the FES-OL, environmental impact appraisals or in any decisions of the Atcmic Safety and Licensing Board; 2) a significant change in effluents or power level; or 3) a matter not previously reviewed and evaluated in the above doctments which has a significant adverse environmental impact.

Therefore, none of these changes involved an unreviewed environmental question.

2.7 Nonroutine Reports Submitted For this reporting period, no nonroutine reports in accordance with EPP Subsection 5.4.2 were submitted.
