s 1.0 Introduction This report describes the implementation of the Environmental Protection Plan (EPP) from January 1, 1986, through Decenber 31, 1986.

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

2.0 Environmental Protection Activities 2.1 Aquatic Monitoring The Environmental Protection Plan states that the NRC wl11 rely on decisions made by the ConTronwealth of Pennsylvania, under the authority of the Clean Water Act, for any requirements for aquatic monitoring. Industrial Waste NPDES Permit PA 0051926 dated Septenber 19, 1984, provides the mechanisms for protecting water quality and Indirectly aquatic blota.

In accordance with the requirements of Section 3 of the Permit, monitoring results were stmnarized 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 Maintenance of Transmission Line Corridors Transmission line nuintenance records concerning herbicide use are being maintained by the Company's Electric 4 Transmission and Distribution Department. As required by the EPP, these records can be made available to the NRC upon request.

2.4 Noise Monitoring The Atomic Safety Licensing Board (ASLB) ruling LBP-83-11, dated March 8,1983, as well as the reconinendations of the NRC staff contained in the Environmental Statement related to the operation of Limerick Generating Station require that 3 Philadelphia Electric Company (PECo) perform postoperational noise surveys to ensure that "Offsite noise levels in the vicinity of the Limerick site during plant operation are not expected to be high enough above ambient levels to annoy nearby residents."

~ .

The operational noise surveys were performed when Limerick Generating <tation Unit No. I was operating at rated capacity. The measurements were conducted during both a defollate and foliate period. Daytime and nighttime sound measurements were taken. The defollate survey was conducted during the period of January 29, 1986, through January 31 1986, and the foliate survey on Jtrie 26, 1986.

All operational measurements were conducted at the same locations where baseline ambient measurements were previously performed. These measurement locations are consistent with the Bechtel 1973 survey (FES Figure 5.7).

All acoustical measurements were made using a GenRad Type 1988-9700 Precision Integrating Sound Level Meter and Analyzer and a GenRad Type 1995 Integrating Real-Time Analyzer. The specifications of both Instrtments meet the requirements for precision (Type 1) sound level meters (ANSI S1.4-1983, IEC 651-1979, DIN 45 633/1-1970, ANSI S1.11-1966, IEC255-1966, and DIN 45 652-1964). Measurements were taken in accordance with ANSI Standard S1.13-1971, " Methods for the ,

Measurement of Sound Pressure Levels."

A review of the operational vs. baseline ambient surveys as compared with currently accepted methods for predicting the potential for conmunity noise annoyance including subjective audibility criteria has concluded the following:

Based on the preferred " Modified Corrposite Noise Rating (CNR) procedure published by the Edison Electric Institute's Electric Power Plant Environmental Noise Guide, the average expected conmunity response at the nearest residences to the operating Station is "No Observed Reaction".

Based on current research (Fidel, S.A., et al, "A (

Graphic Method for Predicting Audiability of Noise Sources" DBM Inc. Report No. 4954, 1982) for calculating annoyance due to audibl11ty of an intruding noise signal, the operational noise sources of Limerick Generating Station are below the criterion level for any average reaction frcm a populated ccrimunity as compared with the baseline arrbient noise surveys.

Since construction of the supplemental coo 1Ing water system .

Is Inccurplete, no snund survey was made at Point Pleasant or Bradshaw.

2.5 EPP Nonccmpliances There were no EPP-noncompliances for this reporting period.

2.6 Changes in Station Deslan or Operation. Tests, or Experiments Environmental evaluations were perfonned for the below -

listed changes in the Limerick Generating Station operation. In accordance with the requirements of Section 3.1 of the Environmental Protection Plan, each IIsted change-Includes a brief description, analyses, Interpretation,.and y evaluation. 1 A. Environmental Evaluation No. 86-1 fi The subject of this evaluation was the temporary _

substitution for 1986 of Instream monitoring of dissolved oxygen levels in place of the 59 F terrperature constraint on withdrawals. This change was evaluated in 1985 and sunnarized in the 1985 Annual Environmental Operating Report. The environmental advantages of directly measuring dissolved oxygen were equally appilcable to 1986. For 1986 PECo's capability for dissolved oxygen monitoring was enhanced as a result of newly Installed automatic D.O.

monitoring and transmitting facilities.

B. Envirorsnental Evaluation No. 86-2 Two changes also authorized for 1985 were examined in Environmental Evaluation No. 86-2. These involved the withdrawal of water from the Schuylkill River for consunptive use at LGS when 1) the consunptive use at Titus Generating Station or Crmby Generating Station was curtalled and 2) the consurotive use was replaced in equal volune by water released from the Still Creek and/or Owl Creek Reservoirs upstream of LGS. M Use of the Titus/Crorrby allocations enhanced the flow In the reach between Titus and Limerick flow by 3.5 mgd over the amount which would occur if Titus were in operation. On the other hand, the reach downstream of LGS to the Crcrrby plant was depleted by 1.7 mgd.

Because the quantitles involved are a very small fraction of the existing river flew, the effect on water quality was deemed to be negliglble.

Use of Still and Owl Creek Reservoirs provides increased flow of high quality water in 77 miles of st rean. Therefore, no water quality problems would be expected in 1986.

These changes were also evaluated for their combined effect on impingement and entrainment. It was determined that because the intake approach velocities would remain at or below the values used in the FES evaluation, no significant change in impingement effects would be anticipated.

The analysis on entrainment effects found that even at the 7 day,10-year Schuylkill River low flow only an additional 5% of river flow would be withdrawn. This does not represent a significant increase in either the withdrawat rate or in the corresponding entrainment of larval fish and eggs.

None of the changes evaluated in 1986 Involved an unreviewed envirormental question. -

2.7 Non-routine Reports Submitted For this reporting period, no non-routine reports in accordance with EPP Subsection 5.4.2 were submitted.
