1.0 Jat.rpluction i This document is the Oyster Creek Nuclear Generating Station (OCNGS) Annual Environmental Operating Report (A[0R) for 1991. This report is required by Oyster Creek Envircnmental lechnical Specification (OCETS) i Section3.5.l(A). i The OCNGS is a single cycle, forced circulation, boiling water reactor of i 620 MWs maximum (sunyner) dependable net capacity, owned by Jersey Central . Power & Light Company and operated by CPU Nuclear Corporation. The OCNGS is located in Lacey Township, Ocean County, New Jersey. The plant is subject to Operating License No. OPR-16. The date of initial reactor criticality was May 3, 1969 and the commercial generation of power began ' on December ?3, 1969.
, This AEOR covers the period from January 1,1991 through December 31, 1991. The report is organized in the following format: i Section 1.0 Introduction Section 2.0 - Environmental Monitoring Section 3.0 - Special Monitoring and Stuoy Activities Section 4.0 Additional Information 2.0 Environmental Monitorina The fishkill Monitoring program was initiated in accordance with Section l.1 of the OCETS, as a result of a planned February 15, 1991 plant shutdown.- In order to document the effects of the station shutdown on the fishes in Oyster Creek, an intensive sampling program was conducted. The :
results of the monitoring effort indicated that an estimated 1,151 fish < died due to temperature stress resulting from the station shutdown. Bluefish accounted for 97 percent of the mortalities. A purposefully slow rate of power reduction and concomitant gradual temperature decay appears : to have . limited cold shock stress and mortality to the species least ' tolerant of cold shock. It is likely that the majority of the bluefish , died within the discharge canal and did not move into Barnegat Bay before j dying, four other fish species that had -been involved in previous , fishkills, including the Atlantic menhaden, were collected in Oyster Creek during pre-shutdown sampling but were unaffected by the february - 15 shutdown.

hecut re Sum ary,
- n ceder to document the of f ects of the Tobruary 15, 1991 anutdown of the oyster Creek fluelear Generating Station en the fishes in Oyster Creek, an intensive sampling program was ccnducted by *PU lluelaar Corporation. The results of that monitoring effert indicatec that an estLmated 1,151 fish died due to temperature stress resulting frem the station shutdown. Bluefish accounted for 97 percent of tr slities. A purposotully slow rate of power reduction and concomitant gradus. .emperature decay appears to have llmited
- eld shock stress and mortality to thr: species least tolerant of cold shock.
It is 1ikely that the majortty of the bluefish died within the discharge canal , and did not move into Barnegat Bay before cying. Tour other fish species that had been involved in previous fishkills, including the Atlantic menhaden, were collected in oyster Greex during pre-enutdown sampling but were unaffected by the february 15 shutdewn.
I M r~curtten This report documents the effects of the February 15-16, 1991 anuteewn of the oyster Creek !1uelear Generattng statten en the fishes in Cyster Creek, based upon sampling condt.cted by GPU tiucisar Corporation. The ma$cr cb3ectives of the san.pl *,ng program were:
- 1) To determine the spectos composition, relative abundance and distribution of fishes in Cyster Creek prior to Station sputdown.
- ) To quantify the extent of any shutdown-induced mortalities.
Oata collection cegan on February 2 and centinued througn February 17, 1991. Oyster Creek fluelear Generating station (oc!!GS), which had operated centinucusly since July 4, 1990, tegan the shutdown procese at noen on February 15, 1991. By approxtmately 0845 hours en February 16, the discharge canal temperature had been reduced frem a pre-snutdown temperature of 62*F to amb. tent temperature of 39'F. dueriale and Metheds P re-s hu t dpyrt E u :-- ays Gill net and botten trawl samples were ecliected, at the statiens inuicated in Fiqure 1, en Fecruary 2-3, 5-6, 9-10, and 13-14, 1991. All sampling was conducted af ter dark. 9ettem trawl samples wure collected at !Lve locations in the discharge
- anal east of the Route 9 bridge, including the langth of two of the
.testdantial lagoond. Trawling was dene with a 4.8 m semicallocn trawl with a 3.9 cm stretch mean tedy, a 3.2 cm streten mean cod end and a 1.3 cm stretch mean liner. One five minute trawl sample was taken at statiens T1, T4 and 75 during eacn campling pericd. At stations T and TJ, the trawl ;
was dragged the lengtn cf t.o restdential lagoons (Fig. 1).
At gill not stations G1, G2, G3 and G4 (Fig. 1), steples were
;ollected with a 60 x 2.4 m monofilan.ent not constating ci two 30 m panels of 3.9 and 8.5 cm streten mesh.
i All fish captured were identified and enumerated; the length range of specimens t each fish species was dstormined. Surface and bottem temperature and salinity measurements were measured with a Beckman 1alinemeter concurrent with each trawl anu gill net sample. ( 3 Hook and lina str;pling was the mest successful methoc of capturing the most abundant species, the bluefish, as well as certain other tracies restdant near the condenser discharge prier to snutdown. H3ek and line stdpling was also used to t.dentify the species of fish observed schooling naar the 30" discharge pipe prior to the snutdewn. Ourtne and Pejt-$hutdewn sugygga Post-Shutdown Trawling - One five-minute bottem trawl was conducted with the trawl described above at trawl stattens Ti, 72, 73, T4 and T5 between 1050 and 1:30 hours en February 16 and again on rectuary 17 frem 1100 to 1230 hours. Additicnally, ten-minute tottem trawl samples were conducted between 09:5 ard 1015 hours en February 17 at trawl stations T6, T7 and 78, which were iccated in Barnegat Bay immediately east, acuth and north cf the mouth of oyster Crook, respect;vely.

The second survey oif the fish fauna of Oyster Creek was conducted on j February 5-6, _1991. The sampling effort yielded 296 fish comprising 18 species (Tables.: and 4) The species of interest with respect to a possible fish kill included bluefish, menhaden and striped bass. Water temperature in the dischargo canal during the sampling period ranged frem 50.4 to 52.7'T (10.2-ll.5'c), while salinities ranged from 22.1 to 23.7 ppt. Bluefish appeared to be ecncentrating in the warmest water, in the eastern-most portion of the condenser discharge. Twelve large bluefish were captured at gill net station G3 during the February 6 sampling effort (Table 2) and an additional 23 bluefish were taken by hook and line at eno cendanser discharge (Table 5). Bluefish were swimming deeply in the eastern-most condenser discharge, and were not observed near the surface. 4 The third pre-outage fish survey was ccnducte ' on Febcaary 9-10, 1991. The sampling effert yielded 1,063 fish comprising 22 species (Tabics 6 and 7). Tha species of interest with respect to a possible fishkill included bluefish, menhaden, specxled se4treut, striped bass and ncethern kingfish.

1 i 13-14 sampling period ranged frem 47 to 49'r (8.1-9.2*C), wnile salinities ranged from 21.5 to 22,1 ppt. Based upon the results of those pre-enutdown sampling efforts, our observations of fish 17, tus disenarge canal,'and our historical data base on fishkills, 1*,.was concluded that there were three fish species at risk of cold-shock that were present in relatively large nummers: 1) several hundred bluefish, 2) several hundred to a few thousand striped bass, and 3) a feu thousand Atlantic menhadt1. Durina and Post-Shutdewn Survevg S*,ation snutdown ecmmenced at approxt=ately 1200 hours on February 15, 1991 wnen am'a ient water temperature (condense!/ intake) was approx Lmat'+1y 41*T. Condenser disenarge t2mperature at that time was approximately 52*F and the Route 9 bridge temperature, 52*F. In order to minimize the impact of station i shutdown on the fishes in the discharge canal, GPUN developed a power reduction plan wnich controlled the effluent temperature reduction at the main condenser disenarge at a rate of-approxtmately 1*? per hour. This rate of temperature change is approximately cne fif th the rate wnien is typically utili:ed to acclimate fish to laboratory conditiens and represents a power reduction scenazio lasting appecxt=ately twice as 1:ng as normal station shutdown. The plan also called for shutting the diluti:n pumps off early in the snutdown process in order to furtner minimi:e the rate of temperature decay in the discharge canal. The relatively slow and untform reduction in power brougnt CCNGS condenser disenarge temperature down to amoient levels over a ~9rted of approximately 20 hours. 7.s a result of tne two cperating dilution pumps cetng taken out of service sequentially at 1149 and 1417 hours, the canal texterature, as measured at the Route 9 bridge, increased stepwise twtce 6

Water l l temperature in the condenser discharge .srea, unarfected by dilution pump- l activity, continued to decline during that period. At approxtmately 0900 hours i on February 16, the entire discharge canal had reached ammient temperature of i about 39'F. During the early hours of the shutdown process on' the af ternoon of February 15, hook and line sampling indicated that bluefien were still tightly concentrated in the eastern condenser discharge bay, swLmmAng close to the bottem. As the snutdown process progressed through the late afternoon and evening hours of February 15, there was no visible evidence of suressed fish in the condenser discharge or anywoere else in the discharge canal. Large numcers of bluefish were observed swimming closer to the surf ace of the eastern-most condenser disenarge bay during the early morning hours of February 16. A total of 93 bluefish were ecliected from this area between 2200 to 0500 hours by dipnet or hook and line. By 0500 hours, the condenser discharge temperature nad secreasec to 43'? and the apparently stressed bluefish began to disperse and move away fr:m the eastern portion of the condenser discharge. The bluefish centinued moving fartner westward and d=wnstream, with many being ocaerved at 0530 6. aura near the eastern side of the peninsula between the c:ndenser and dilution disenarge structures. Between 0630 and 0800 h:urs, water temperatures were cbserved : be approxLmatnly 1.5'F higner near the diletten discharge structure : nan at the condenser disenarga and the bluefish appwared to have been attracted by this pocket of warmer water. These fian were severely stressed and 200 were dipnetted f r:m this area during th: s 1.5 hour perted. Further dcwnstrea=, several Iccal fisherman dipnetted a retal of 47 bluefish frem the disenarge canal at the Reute 9 bridge between 0630 and 1000 7
hours. GPUN workers in a small boat dipnetted 52 bluefish between 0630 and 0800 hours, plus an additional 91 bluefish between 0800 and 1000 hours, from i the discharge canal west of Rouce 9. An additional 22 dead bluefish were a collected frcm the discharge canal banks a.sd areas eaar of Route 9 between 0800 and 1700 hours. Stressed and dead fish were also collected by GPUN permannel walking along the banks of Oyster Creek, out to Barnegat Bay, between 0800 and 1700 hour 1 on February 16. Three bluefish were collected from the 30" discharge pipe area and the south bank of the discharge canal, and 10 were taken along the north canal bank. An additional 5 bluefish were collected at the mouth of oyster Creek &long the north shore beach. Four bluefish were also dipnetted by the consultant conducting the trawl surveys between Route 9 and the mouth of Oyster creen. Thus, it was apparent that the vast ma]ority of the stressed and dead fish were collectud near the plant with gradually decreasing numoors observed in areas further downstream. *n addition to the bluefish, small numbers of dead or stressed spot (20 individuals), speckled seatrout (11), smooth dogfish (3), weakfish (1), nortnern kingfish (1), and Atlantic heertng (1) wete found
~
along the tanks, primarily west of the Ro,te 9 tridge. The dead and stressed bluefish c 'aected rangec frem 250 := 875 mm (9.75 to 34.5 inenea) in length. Post-Shutdewn Trswl su r rave Post-anutccwn trawl surveys were conducted on February 15 and 17 at the same five statiens along the diacnarge canal at which pte-shutdown trawls had been conducted. Three additi0nal POat-shutdcwn trawls were also cellected February 17 in Barnega 3ay immediately outside tne mouth of Oyster Creek (Figure 1). only one additional stressed bluefish was , S
collected (at station T2) during the post-snutdcwn trawling, confirming that frv stressed or dead fish had moved east of Route 9. The' Atlantic-i nenhaden, a species wnich has been susceptible to cold shock during J previous winter shutdown event.s, did not appear to be affected by the February 15 shutdown and were collected alive in small numbers during the post-shutdown trawling. Likewise, the 14 other species collected during post-shutdown trawling showed no apparent signs of cold shock (Tables 9, 10 and 11). Post-Shutdown Diver surveys A total of 19 diver transects were conducted between the discharge stEctures and the mouth cf Oyster Creek. The diver survey. began at 0830 hours February 16 and the last transact wa9 completed at 1220 hours on February 17. All but five of the 34 cetal fish observed by the diver were " blu Jish, corroborating that biuelish was the predominant species involved in this fishkill (Tacle 12). Only one of the dead bluefish observed during tne diver transects was located east of Route 9, with the majority of cold shocP deatna occur:Ang between the disenarge structures and the trestle bridge. In addition to the bluefish ocserved by the diver, one speckled seatreut (Cvnescion nebulosus) was collected slightly upstream of the trestle bridge. Tha other f:ur dead fisn ocserved were single specimens of winter flounder, American eel, snverside and menhaden. Because the lat"er f:ur specimens were all collectec immestately downstream of the screenwasn disenarge pipe near the dilution disenarge, they are thougn to have been disenarged from the-screenwasn pipe fcilowing impingement en the traveling screens rather than ceing vtet w.s of ctld snock following CCNGS shutdown. 9 I

I For the only species found in abundance, bluefish, tne number of individuals per square foot along each transact was determined. These densities were used to estimate the nummer of bluefish on the entire discharge canal bottom from the OCNGS discharge structures to the. .nouth of Oyster Creek. A total of 509 dead bluatish were calculated to have fallen to the bottom of the discharge canal (Table 13). During their diving activity on February 16, the divers observed fish including scriped bass swimming in the vicinity of the 30 inch discharge pipe, just downstream of the condenser di .:harge. These fish scattered as the diver approached indicating that they were not adversely affected by the station snutdown. Conclusiens Pre-sht- t ant surveys of oyster Creek indicated t.'s presence of a wide variety of fish species including six species that have been involved in past shutdown-related fishx'..la ( '. . e . , bluefish, blueback herring, Atlantic menhacen, northern kingfish, wnita peren and bay anchovy) . These surveys, conducted over tua two weex pericd immediately prior tc the staticn shutdown, i revealed tnat the numcer of species and aoundance of most spacies in the dimenarge canal remained relatively uniform. Large numbers of bluefish, and t 1: lesser nummers of specxled seacrout and striped bass were noted during this 1 t period near the staticn discharges. Furtner dowastream in the discharge canal, bluecack herring was the species found in the greatest abundance during pre-shutdown surveyn. The sta:Lon snutdown sequence resulted in a gradual reduction of c0ncenser discharge temperature at a rat 9 of about l'F per hour. This relatively sicw and uniform decrease in the temperature of the OCNGS heated offluent to wnich 1 l 10
the fiah were exposed was apparently beneficial in limiting the extent of the fishkill to those species most eusceptible to cold shock. Mout bluefish did not appear to be severely stressed until several hours after initiation of station shutdown when the condenser discharge temperature had bean reduced frem 62'F to about 45'F. They then began to die rapidly, especially near the dilution disenarge, after a pocket of relatively war.n and calm water to which they wore attracted had eccled wicnificantly. Based upon the diver survey, an estimated 509 bluefish died and sank to t4x bottom of the discharge canal. An additional 605 individuals of this species were dipnetted, resulting in a total of 1,114 bluefish. A total of 37 dead or stressed individuals of 6 additional species were f und following the shutdown. Striped bass, Atlantic menhaden, bluecacx herring, white perch and bay anchovy were net adversely af fected by the February 15-16 station shutdown even thougn all but the striped bass have been involved in previous cold-shock ('[. telated fishkills, in su==ary, the nu=cer cf fish anvolved in the fishkill of February 15-16, by species, was as follows: bluefish 1,114 (actual ecunt & e.itimate frcm diver surveys) spo: 10 (actual ecunt) speckled seatrout 11 (actual counti smooth dogfinn 2 (actual ccant) weakfish i (actual ecunt) ncethern kingfish .

l l i (Durham/C3302295) I 1991 ANNUAL ENVIRONMENTAL OPERATING REPORT OYSTER CREEK NUCLEAR GENERATING STATION LICENSE NO. DPR-16 DOCKET NO. 50-219 e , . PREPARED BY: GPU NUCLEAR CORPORATION FEBRUARY, 1992 4)g3/ O1/ ' 3.107WF1Jtt l.0 Introduction This document is the Oyster Creek Nuclear Generating Station (OCNGS) , Annual. Environmental Operating Report (AEOR) for 1991. This report is j required -by Oyster Creek Environmental Technical Specification (OCETS) i Section 3.5.l(A). I The OCNGS is a single cycle, forced circulation, boiling water reactor of ! 620 MWs maximum (summer) dependable net capacity, owned by Jersey Central Power & Light Company and operated by GPU Nuclear Corporation. The OCNGS is located in Lacey Township, Ocean County, New Jersey. The plant is subject to Operating License No. DPR-16. The date of initial reactor criticality was May 3, 1969 and the commercial generation of power began on December 23, 1969. This AEOR covers the period from January 1,1991 through December 31, 1991. The report is organized in the following format: Section 1.0 - Introduction Section 2.0 - Environmental Monitoring Section 3.0 - Special Monitoring and Study Activities Section 4.0 - Additional Information 2.0 Environmental Monitorina The Fishkill Monitoring Program was initiated in accordance with Section 1.1 of the OCETS, as a result of a planned February 15, 1991 plant shutdown. In order to document the effects of the station shutdown on the fishes in Oyster Creek, an intensive sampling program was conducted. The results of the monitoring effort indicated that an estimated 1,151 fish died due to temperature stress resulting from the station shutdown. Bluefish accounted for 97 percent of the mortalities. A purposefully slow rate of power reduction and concomitant gradual temperature decay appears to have limited cold shock stress and mortality to the species least tolerant of cold shock, it is likely that the majority of the bluefish died within the discharge canal and did not move into Barnegat Bay before dying. Four other fish species that had been involved in previous fishkills, including the Atlantic menhaden, were collected in Oyster Creek during pre-shutdown sampling but were unaffected by the February 15 shutdown. A copy of the Fishkill Monitoring Program Report submitted to the NRC on March 16, 1991 is provided as Attachment I. 3.0 Special Monitorina and Study Activities This section is intended to present the results of any special monitoring and study activities required by Section 2.0 of the OCETS. Section-2.0 of the OCETS did not require the performance of any special monitoring or study activities during this report period. 11tv10Lar i 4.0 Additional Information This section reports any additional information - that is required by Section-3.5.1 of the OCETS which includes a sumary of: I a) - All OCETS Non-Routine Environmental Operating Reports (NE0R) and the l corrective action taken to remedy them. b) Changes made to State and Federal Permits and certificates which pertain to the requirements of the OCETS. c) Changes in station design which could involve an environmental impact. d) Changes to the OCETS. 4.1 Sumary of OCETS NE0R A NE0R was filed with the NRC on March 16, 1991 concerning a fishkill event described in Section 2.0 of this report. As indicated previously, a copy of the Fishkill Monitoring Program Report is provided as Attachment 1. Although not required by the OCETS, GPUN is including (Attachment -II) copies of the non compliance reports submitted to the New Jersey Department of Environmental Protection and Energy during this reporting period for non-compliances with NJPOES Permit No. NJ 0005550. These permit non-compliances were minor in nature and did not result in an impact to public health or the environment. Summary of Chanaes Made tg. Federal and State Permits and Certificates which Pertain to the Reouirements of OCf.J1 There were no changes to Federal and State permits and/or certificates per'aining-to the OCETS during the reporting period. Sumary of Chanaes in Station Desian Which Could involve and Environmental imDack There were no changes in, or modifications of, station design during the reporting period which could involve an environmental impact. 4.2 Sumary of Chanaes to the OMJJ There were no changes to the OCETS during the reporting period. i smmn .4w - p m- e,- s i sn= ,-- m 4 ,- L , - _. -- z_wh J A1TACHMENT I FISHKILL MONITORING PROGRAM REPORT MXT712f t 4 WINTER OUTAGE .TISH SAMPLIM PROGRAM REPORT TOR THE PERIOD TEBRL'ARY 1991 i GPU :!uclear Corporation { Oyster Creen Environmental Controls i March 1991 i , _. n -. __ _ _. _. _ _ .

The major objectives of the sampling program weret g ;) To determine the species eceposition, relative abundance and distribution of fishes in Oyster Creek prior to Station shutdown.
- ) To quantify the extent of any shutdewn-induced mortalities.
Data cellection began on February 2 and continued through Faeruary 1", 199;. Oyster Creek Nuclear Generating Statien (OCNGS), which had operated cent;nucusly sinec July 4, 1990, regan tne snutdown process at noon on February 15, 1991. By approxt=ately 0845 hours on February 16, the disenarge canal temperature had been reduced from a pre-snutdown temperature of J!'T to ambient temperature of 39'r. Materials snc uethods P r e- P.u t d own S u rra v ai 0111 net and bottom trawl samples were : llected, at tne stati ns indiested in Figure 1, on Fecruary -3, 5-6, 9-10, and 13-14, 1991. All sampling was Conducted after dark. Sctt m trawl samples were eclie:ted at five locations in the disenarge
- anal east of the Route 9 bridge, including the length Of two of the residential lagcons. Trawling was done with a 4.8 n semiballoon trawl with a 3.9 cm streten mesn bcdy, a 3.; rm stret:n mesh ced end and a 1.3 cm strut:n mesn liner. One five minute trawl sample was taken at stati:ns T1, T4 and T5 during eacn samplang perled. At stat; ns T2 and T3, the trawi saa dragged the lengtn Of tne residential lagoons (Fig. 1).
6 I At gill not stations cl, G2, C3 and G4 (Fig. 1), samples were ' collected with a 60 x 0.4 m monofilacent not consisting of two 30 m panels of 3.9 and 8.5 em stretch mesh. All fish captured were identified and enumerateds the length range of specimens of each fish species was determined. Surface and bottom temperature and salinity measurements were measured with a Beckman salinometer concurrent with sach trawl and gill not sample. Hook and line sampling was the most successful method of capturing the most abundant species, the bluefish, as well as certain other species resident near the condenser discharge prior to shutdown. Hook and line saipling was also used.to identify the species of fish observed schooling near the 30" discharge pipe prior to the shutdown. Durine and Post-Shutdevn Surveys Post-Shutdown Trawling - one five-minute bott:m trawl was conduered with the trawl desertbed above at trawl stations T1, T, T3, T4 and T5 between 1050 and 1:30 hours on February 16 and again on Feoruary 17 fr:m 1100 to 1:30 hours. Additienally, ten-minute bcutem trawl sampien were conducted between 0925 and 1015 hours on February 17 at trawl stations T6, T7 and TS, which were located in Barnegat Bay immediately east, south and north of the mouth of Oyster Creek, respectively. All fish captured were identified and . enumerated; lanyth ranges were cctained.

Peut-Shutdown Diver Survey A ' hardhat' diver survey was conducted following station shutdown to determine the specias composition and abundance of fish which sank to the bottem of the discharge canal after death. ,A total of 19 transects were conducted between the OCNGR tischarges and the mouth of Oyster Creek, including two transects within residential lagoons (Figs. 2 and 3). Transacts D7 through D19 were sampled between 0830 and 1600 hours on February 16. Transacts D1 through D6 were sampled between 0800 and 1:05 hours on February 17. All fish within an arm's length of the diver were identified and enumerated. For the only species found in abundance. bluefisn, the number of individuals per square foot along eacn transect was determined. These densities were used to estimate the number of bluefish en tne entire canal bottom frem the OCNGS discharges to the mouth of Oyster Creek. Fesults and Discussion Pre-Shutdewn Trawline and Gill Netting The initial survey of the finn f auna of Oyster Creek en February 2-3 yielded a total'of 1.537 fjsh ccmpr stng 20 spectos. The spectos of interest with respect to a possLble fishkill based upon previous cold-shock experience included bluefish, Atlant;; mannacen, wntre peren, black sea bass and Atlantic herring.

The sampling effort yielded 296 fish comprising 18 species (Tablee 2 and 4}: The species of interest with respect to a possible fish kill included cluefish, menhaden and striped bass. Water tamperature in the discharge canal durtng the sampling period ranged f ro:s 50.4 to 52.7'T (10. 2-ll.5'C), while salinities ranged from 22.1 to 23.7 ppt. Bluefish appeared to be concentrating in the warmecc water, in the eastern-most portion of the condenser discharge. Tvelve large bluefloh were captured at gill not station G3 during the february 6 sampling effort (Table 2) and an additional 23 bluefish were taken by hook and line at the condenser discharge (Table 5). Bluefish were swimming deeply in the , eastern-most condenser discharge, and were not observed near the surface. The third pre-outage fish survey was conducted on February 9-10, 1991. The sampling effort yielded 1,063 fish comprising 22 species (Tables 6 and 7). The species of interest wtth respect to a possible fishkill included bluefish, mennacen, specxled seatrout, striped beas and northern kingfish. Water temperature in the disencrge canal during the third sampling perted ranged frem 50.7 :: 5;.3*? (lO.4-ll.J'C), while salinities. ranged from 22.1 to 20.7 ppt. The fourth and final fisn survey :sfore the plant shutdown was conducted en Tebruary 1.i-14. 1991. The sampling effort yielded 374 fish compr:, sing 20 species. The specten of interest with respect to a fishkill included bluefish, mannaden, specxled seatrout and striped bass (Tables 7 and 8).

Based upon the results of these pre-shutdown sampling efforts, our observations of fish in the discharge canal," and our historical data base on fishkills, it was concluded that there were three fish species at risk of cold-shock that were present in relatively large numberst 1) several hunared bluefish, 2) several hundred to a f ew thousand striped bass, and 3) a few thousand Atlantic menhaden. Durine and Post-shutdown survevs Station snutdown commenced at apprcxt=ately 1200 hours on February 15, 1991 wnen am'ient m water temperae.ure (condenser intake) was approximately 41'r. f Cendenser disenarge temperature at that ti=e was approximately 62*P and the Route 9 bridge temperature, 52*F. In order to minimize the impact of station shutdown on the fishes in the discharge canal, GPUN developed a power reduction plan wnich controlled the effluent temperature reduction at the main condenser disenarge at a rate of approximately 1*? per hour. This rate cf temperature enange is a9 proximately one fifth the rate wnich is typically utili:ed to acclimate fish to lacoratory condittens and represents a power recuccion scenario lasting approx;mately twice as icng as normal station shutdown. The plan also called for shutttng the dilutten pumps off early in the snutdown procese in order to further minimate the rate of temperature decay in the disenarge canal. The relat;vely slow anc uniform reduction in power trougnt CCNGS condenser disenarge temperature cown to ambient levels over a period of approxt=ately 20 hours. As a result of tne :wo operating dilutien pumps teing taken out of service sequentially at 1149 and 1417 hours, the canal temperature, as measured at the Route 9 bridge, increased stepwise twico 6 . _ _ - - . - _ _ . - - . _ - -- . - - - . ~ - . . ~ . . . -- . - - -. i between 1200 and 1700 hours and then slowly decreased (Fig. 4). Water temperature in the condenser discharge area, unaffected by dilution pump activity, continued to decline during that period. At approxLmately 0900 hours , I on February 16, the entire discharge canal had reached amoient temperature of about 39'F. During the early hours of the shutdeva process on' the af ternoon of February i 1 15, hook and line sampling indicated that bluefish were still tightly l concentrated in the eastern condenser discharge bay, swimming close to the l bettes. As the shutdown process progressed through the late afternoon and j evening hours of February 15, there was no visible evidence of stressed fish in the condenser discharge or anywnere else in the discharge canal. Large numoers of bluefish were coserved swimming closer to the surf ace of the eastern-most cendenser disenarge bay during the early morning hours of . February 16. - A total of 93 bluefish were collected from this area between 2000 to 0500 hours by dipnet or hook and line. By 0500 hours, the condenser discharge temperature had decreased to 43'r and the apparently stressed bluefish began to disperse and move away from the eastern portion of the condenser discharge. The cluetish continued moving further westward and downstream, with many being coserved at 0530 hours near the eastern site of the peninsula between the condenser and dilution disenarge structures. Between 0630 and 0800 hours, water temperatures were observed to be approximately 1.5'r hagner near ne dilution disenarge structure than at the condenser disenarge and the cluefish appeared ta have been attrac* c by this pocket of war =er water. These finn were severely stressed and 300 were dipnetted from this area during snas 1.5 hour period. Further downstream, several local fishermen dipnetted a total of 47 bluefian frem the disenarge canal at the Route 9 bridge between 0630 and 1000 7 . . .- .. . ~ - - _ - _ - . .- - - . . . - . - , . - _ . - . hou t*s . GPUN workers in a small boat dipnetted 52 bluefish between 0630 and 0800 hours, plus an additional 91 bluefish between 0800 and 1000 hours, from the discharge canal west of Route 9. An additio.tal 22 dead bluefiah were collected frem the discharge canal banks and areas east of Route 9 between 0800 and 1700 hours. Stressoa and dead fish were also collected by GPUN personnel walking along s the banks of Cyster Creek, out to Barnegat Bay, between 0800 and 1700 hours on February 16. Three bluefish were collected from the 30" discharge pipe area and the south bank of the discharge canal, and 10 were taken along the north canal bank. An additional 5 bluefish were collected at the mouth of Oyster Creek along the north shore beach. Tour bluefish were also dipnetted by the consultant conducting the trawl surveys between Route 9 and the mouth of Oyster Creek. Thas, it was apparent that the vast majority of the stressed and dead fish were collected near the plant with gradually decreasing numbers observed in areas further downstream, in addition to the bluefish, small numbers of dead or stressed spot (20 individuals), speckled seatrout (11), smooth dogfish (3), weakfish (1), northern kingfish (1), and Atlantic herring (1) were found along *he =anks, prLmartly west of the Reute 9 bridge. The dead and stressed bluefish cellected ranged frcm 250 to 875 mm (9.75 to 34.5 inenen) in length. Post-shutdewn ?rswl sur evs Post-ahutdown trawl sutveys were conducted on February 16 and 17 at the same five stations along the--disenarge canal at which pre-shutdown trawls had been conducted. Three additional post-shutdown trawls were also-collected February 17 in Barnegat Say L= mediately outside the mouth of Oyster Creek (Figure 1). Only one additional stressed bluefish was S -.-~ . - . - _ ~ . . - - . - - - . - ~ - - ~ . . . - - . - - - . . ollected (at station TI) during the post-snutdown trawling, confirming that few stressed or dead fish had moved east of Route 9. The Atlantic menhaden, a species which has been susceptible to cold shock during previous winter shutdown events, did not appear to be affected by the February 15 shutdown and were collected alive in small numbers during the post-shutdown trawling. Likewise, the 14 cther species collected during post-shutdown trawling showed no apparent signs of cold shock (Tables 9, 10 and 11). Peet-shutdown Diver surveys A total of 19 diver transects were conducted between the disenarge structures and the mouth of Oyster Creek. The diver survey began at 0830 hours February 16 and the last transect was completed at 1 20 hours on February 17. All but five of the 34 total fish observed by the diver were bluefish, cerroborating that bluefish was the predominant species Anvolved in this fishkill (Table 10). Only one of the dead bluefish observed during the diver transacts was located east of Route 9, with the ma]ority of cold , shock deachs occurring between the disenarge structures and the trestle 4 bridge. In addition to the bluefish observed by the diver, one speckled seatrout (evncecien neeulesus) was collected slightly upstream of the trestle bridge. The cener four dead !Lan observed were single specimens of winter flounder, American eel, salverstde and conhaden. So,cause the latter four_ specimens ware all collected immectately downstream of the screenwasn disenarge pipe near tne dilutton disenarge, :ney are thougnt to have been disenarged from the screenwasn pipe f ollowing impingement on the traveling screens ratner than cetng victims of cold snock following OCNGS snutdown. l-9 - - _ . . . - - . _ . - . .- . .. - - - . - . - - . - . .. - ~ - .-_ - - ~ . .~-_.- - - . l l For the only species found in abundance, bluefish, the number of individuals per square foot along each transact was determined. These densities were used to estimate the number of bluefish on the entire discharge canal bottom from the OCNGS discharge structures to the mouth of oyster Creek. A total of 509 dead bluefish were calculated to have fallen to the bottom of the discharge canal (Table 13). During their diving activity on February 16, the divers observed fish including striped bass swimming in the vicinity of the 30 inch disenarge pipe, just downstream of the condenser discharge. These fish scattered as tne diver approached indicating that they were not adversely affected by thi station shutdown. . Conclusieng Pre-shutdown surveys of Oyster Creek indicated the presence of a wida variety of fish species including six species that have been involved in past shutdevn-related fishkilla (i.e., t'uefish, bluehack herring, Atlantic menhaden,-northern kingfish, white peren and bay anchovy). These surveys, t conducted over the two ween period immediately prior to the station shutdown, revealed snat une nummer of spectes and acundance of most species in the disenarge canal remained relatively uniform. I.arge numbers of bluefish, and lesser. numbers of speckled seatreut and striped bass were noted during this pericd near the station etisenarges. Further downstream in the discharge canal, bluecack herring was the species found in the greatest abundance during pre-shutdown surveys. L . The station snutcown sequence resulted in a gradual reouctaen of condenser disenarge temperature at a rate of ateut 1*? per hour. This relatively slow and uniform decrease in the temperature cf the OCNGS heated effluent to wnich 10 the fish were exposed was apparently beneficial in limiting the extent of the fishkill to those species most susceptible to cold shock. Most bluefish did not appear to be severely stressed until several hours after initiation of station shutdown when the condenser discharge temperature had been reduced from 62'T to about 45'T.
- hey then began to die rapidly, especially near the dilution discharge,.after a pocket of relatively warm and caim water to which they were attracted had cooled significantly. Based upon j the diver survey, an estimated 509 bluefish died and sank to the bottom of the disenarge canal. An additional 605 individuald of this species were dipnetted, resulting in a total of 1,11; bluefish. A total of 37 dead or stressed individuals of 6 additional species were found following the shutdown.
Striped bass, Atlantic canhaden, blueback herring, white perch and bay anchovy were not adversely af f ected by the February 15-16 station shutdown even thougn all but the striped baas have been involved in previous cold-shock related fishkills. In summary, the nur.cer of fish involved in the fishkill of February 15-16, cy species, was as follows: bluefish 1,114 (actual : cunt & estimate fr:m diver surveys) spot 20 (actual : unt) speckled seatreut 11 (actual counti smooth dogfish 2 (ac: tal reunt) weakfish 1 tactual ::unt) northern kingfish . factual : cunt) Atlantic herring .

CAUSE OF NONCOMPLIANCEt control Room operators noted increasing main condenser delta T and alerted electricians to prepare valve alignment for backwash. Before the necessary alignments were completed, the delta T reached 23.7'T at 2307 hre. Backwashing of the main condenser began at 2324 hre. and load was decreased in to reduce the non-complying condition. DISCRIPTION OF NONCOMPLIANCE DISCHARGE: .The discharge / intake temperature difference of the main condenser cooling water exceeded the permit limit of 23'r with four circulating water pumps operating. D7PATION OF NONCOMPLIANCE Seventeen minutes (2307 to 2324). CORPECTIVE ACTION TO pet # E NON-COMPLYING DISCHARGE: Load was-reduced 1% for 1.5 hours and the main condenser was backwashed twice to reduce the delta T.
