i 1.0 Introduction ,

This report describer. the Inplementation of the Environmental Protection Plan (EPP) frm January 1,1987, thrergh December 31, 1907.

Provided he cin are surrorles and results of the environmental protection activities recuired by Subsection 4.2 of the EPP.

2.0 Environmental Prctection Activities 2.1 Acuatle Monitoring The Environmental Protection Plan states that the NRC will rely on decisions mode by the Cornrremalth of Pennsylvania, under the outhority of the Clenn Water Act, for any reautrerents for aquatic ronitoring. Industrial Waste NPDES Permit PA 0051926 dated September 19, 1984, provides the rechanists for protecting wate ouality and Indirectly acuatic blota.

In accordance with the requirecents of Section 3 of the Permit, monitoring results were sumort:ed for each rnnth and reported on Discharge Monitoring Reports which were subnitted to the DER and EPA.

2.2. Terrestrial Monitoring No teet estrial trenitoring 15 required.

2.3 [aintenance of Transmission Line Corridors Transmission line reintenan:e reco ds concerning herbicide use are being raintained by the Canpany's Electric Transmission and D? stribui ten Departrent. As recu! rec by the EPD, th9se records can be rede avallable to the NP.C upon recuest.

2 . L, Notse PonttnrIng No nc.se survey 3 wJre recuired in 195'. The post operational survey for LGS Unit I was cocoleted in 198b. Since corst uction of LGS Unit 2, Point Picastnt, rind Dredshav Reservoir was not ccToleted in 19S7, no sound surveys wcre rode.

c. Finding Nteter AL87-172-01 Idcrtified a failure to take samples from the Plant Outfall cnd failure to take the required ntrber of surples for chlor ide anelvr.is on November 13, 19E7 In accordance witn t.GS iPDES Pennit PA 00',' 926 ATendment No. 2. The proper nethod for obt aining and analy: Ing discharge samples was reviewed with the balance of plant technicians by their supervisor,

b. Finding Nurber AL87-172-02 was issued for fallu e to sa ple and analyze treated radwaste di',charces for toxic metal and organic pollutants a5 required by NPDc5 Pennit PA 0051926, Recui rernent G. A sarple was obtained frcm the floor drain sarple tank (last point prior to discharge) and sent of fside for the required analyses.

2.6 Chances in Station Deslan on Operation, Test, or Experirents Envirorrental evaluations were perfortned fcr the (n110 wing chan es th the Linwrick Generating Station operation. In s

accordance with the reculrorents of Section 3.1 o# the invircrr, ental Protection Plan, each change inclu,.es a t.-le' description, enalyses, interpretation, and evaluction,

a. Environmental Evalug lon he 87-1 Envirorrental Evaluation Nc. C7-1 a!sessed the effe:t of the :or.tinuation in 19E7 c 4 three ternporary changes In plant operatlon. These involved the witFerawai of water frcn the Schuylkill P!ver for contunptive use et LGS. ihe charge < were:

1. substitution of Inf tream renitoring of dissolvet or.cen IcVels in picce of the $c3 temperatu e cccstraint on withdrawals:

2. consteptive 'se at LGS vr.en contumtive use at Titus Generating Station or Crort.s kmerating Station was cu-tailed; aa

3. constret Ive ust at 8.05 when an ecual volune cf water was relonaed fecm Borcunh cf Ter.coua Reser<oi r upstream of LGS.

u ,

The !nstream ronitoelng of dissolved cxygen level!. wat evaluated in 1985 and was strmrl7ed in the 1905 Annual Envi ronme-tal Ou -o'. ..)g Report. The envirorrental c.dvantages of directly reasuring dir.3th 4 cxyge.

< continued to be coplicabic in 1987. Autcmat ic D.C.

rmnitoring and transnittino fcctilties, which were Installed in 1986, continued to be. used.

' Use of the Tit us/Crcrby allocations enhanced the, ficw in the reach between Titus and Limerick by 3.5 mgd over the atrount which would occur if Titus were in operation.

On the other hand, the reach dcwnstream of LGS to the Cecnby plant was depleted by 1.7 mgd. Because the ouantitles involved were a very small fractler of existing river ficw, the effect on Schuylkill P.lver water cuality was determined to be negligible.

Environrrental conttoring in 1985 and 1986 conf;rmed the negligible effect on water cuality.

The use of water from the Borough of Trrnequa reservoirs provides increased flow of high cuality water in 77 miles of stream. Ther*fe., no water cuel!ty p obler+

vere e pected in 19D.

These changes were also evalua*.er) for thc;r ccroined offect on inpingement and entralrrient. S rce these changes were re e under the sa w docket condition as in 1986, no significant e"ects were exr..cted. The 1986 rienitoring prograri found no significant of'ects.

E. Envi- rrental Evaluation fe. f7-2 Environre ..at Evaluttion No. 67 '. nssessec' the roc'liicatian c' the design of tho Erats' ta Resersoir.

The cesign was rodified to preserve an e.rea classified as wetlands by the Corps of Engineer 5. The area of the reservoir was reduced frcn a water surfr.ce arer. of 16 acres to 7 acres and cacac!!y was e:xed frcm 7C rillion gallons to 25 r'llion gal' ens. On Decerbe.* 30, 1966, the .EF !ssued Femit tc. D09-?PA for the rodified cesign.

TM reductinn in the reservoir's si7e and cacccitv will have no significant en*1ro-rrn'.ai effect:. The. rete of f 1 &.' tr.tc th. %st Crerch Perkicren Creen util be unchenged becauf.c there will be. no change in the ntrbe r, si;e, or plan of operation of the ptrps.

The reeller reservoir will increase slightly (from 2 0%

to 50%) the rm centage of sollds that will pass through the Bradshav Peservoir. Therefore, the water dcmstretm o# the Reservoir ulll have r. lightly more suspended sollds than under the original desinn.

However, the DER in issuing the NPDES permits for

. discharges to the East Branch Perkicron Creek and tbrth Itranch Neshaminy Creek will set appropriate limits to assure that- all applicable water quality standards will j l'e rut for the two stretms.

Seepage is expected to be minimal because the rmad1 fled I reservoir will be provided with a two-foot thick Imprevious blanket liner. Additionally, the smaller area of the modified reservoir will result in reduced total scepage.

None of the changes evaluated in 1987 Involved an unreviewed envi rorrmnt question.

2.7 tbn - rout i ne Reports Submitted Two non-routine reports were submitted in accordance with EPP Subsection 5.4.2*

A. On February 13, 19P7 a sanitary sewer line overficwed. The Pennsylvania DER was Infonned by letter dated February 25, 1987.

E, . An NODES violatten for Aver..ge Total Suspended Sollds (~FC) at Discharge Point 201 occurred in AprII. The Fennsylvania DER war. informed by letter dated May 28, 1987.
