The licensee was taking leakage rate, data on a'two ho,tr basis on January 10-11, 1974.. Measured leakage.(unidentified) varied from 2.78 to 4.13 gpm. The source of leakage'was attributed.to_asleaking-condensateJdrain valve for Isolation Condenser B, No. V-14-37,_which was identified on the afternoon of' January 11, 1974, when test equip--
!
mentLwas installed. Between 1:00 p.m. and 9:00 p.m., January.11, 1974 unidentified leakage varied from 3.47 to 2.87.gpm. -No change
in identified leakage was observed. Technical Specification 3.3.D requires the reactor.to be placed in the cold shutdown condition if unidentified leakage exceeds 5 gpa and additionally if. total leakage j

exceeds.25 gpm. Records reviewed indicated the referenced limits were not exceeded.

Environmental i
Fish kill The inspectors met with licensee representatives on the evening of January 11, 1974 to discuss the method in which the plant would be
shutting down and the possible subsequent. fish kill due to lowered temperatures in the discharge canal.
(Paragraph 3 provides data bdQ on thes nrate of decrease in power level; uode of circulating and
'
_
'
dilution pump operation; and temperatures recorded for plant intake and' discharge and at the Route 9 bridge).
j At approximately 2:00 a.m. the inspectors toured the canal area at the plant discharge and observed a considerable number of menhaden congregated at the plant circulating water discharge point. There
were no signs of distress in the fish observed.
From approximately 8:00 a.m. until 10:30 a.m. on January 12, 1974 the inspectors tuared the discharge canal area, from the plant to the lagoons.near the point where the' canal empties into Barnegat Bay.
At that time several dozen bluefish and a few menhaden were observed dead along the canal.. The R0:1 consultant also accompanied theT inspectors during the later portion of this period.
(RO:1 Consultant's report is included as Attachment 1.)
At approximately 11:00 a.m.-the-inspectors returned to the area of circulating pump discharge at the plant and observed a large number (several hundred) of menhaden congregated in an area of relatively

--5-still water at the dilution pump discharge point.
(See Exhibit 1 '
3,,
which shows three photographs of this.) The inspectors were accom-
.% i panied at this point by a representative of the State of New Jersey.
"'
Dilution pumps were off.
Occasionally a fish was observed to be in
-
distress, then rise to the surface, and subsequently sink to the bottom - apparently in the act of dying.
(See Exhibit 2 which shows two photographs of fish in distress. The water temperature in this area was measured by the licensee's consultant and found to be 380F as compared to 36oF at the circulation pump discharge.
At approximately 1:30 p.m. the inspectors again toured the discharge canal in the area of the Route 9 bridge. At this time menhaden were observed to be dead and dying in this area of the canal. People were along the banks catching the fish in distr'ss and placing them into e
pails, etc.
This action continued for several hours.
The inspectors met with the RO:I consultant, and it was decided that the RO*I consul-tant would remain at the fccility to (1) observe subsequent develop-ment, and (2) participate with State of New Jersey personnel in
sampling to be done on January 14, 1974. Based on discussions with all those involved, the indications at this time were that this fish kill was not as extensive as the previous winter fish kill in January 1973.
On January 15, 1974 the RO:I consultant reported to the inspectors 4499 that, based on his observations, he estimated that about 10,000 fish had been killed with all but a few dozen being menhaden.
It was noted,
,
however, that the majority of the menhaden were 12 to 14 inch adults, as compared to the January 1973 fish kill in which the menhaden had been primarily juveniles.

' January 12 -
. 9:00 A.M.
Noticed about 10 large menhaden dead or flopping along the-south bank of Oyster Creek near Highway.9 bridge. Two fish tmen
' $*
emptied a bag with 10 bluefish, 9-14 inches fork length, and 5 men-
^
haden, 8-11 inches fork length. They said the fish started to show distress about'5 A.M. and they had gotten all the bluefish but not all the menhaden. They estimated that.there were 10 times as many menhaden as blues.
9:30 A'M.
Went out in boat operated by Resource Management Incorporated,
.
(RHI), Cruised down Oyster Creek to the entrance to Barnegat Bay.
Saw a.few menhaden along the bank and saw several fisherman pick
.up-a couple of fish near the entrance.- They said they had a couple bluefish but saw mostly menhaden.
Another RMI boat was looking for fish along the bank. They reported the following:
Buoy No. 6 (at entrance) 430F top and 360 bottom.
Said very few fish seen, all menhaden, along the bank.
11:00 A.M.
Contact reported 450F about 1-1/2 feet below surface by the
'-
Sand Point Marine recording thermograph.
1" 11:30 A.M.. Most of those that met later in the conference room went to the discharge ' structure.
Several:hundred large menhaden were schooled and-rwimming in the dilution pump discharge bays. One or two circu--
lating pumps were.on in the plant discharge bays with a noticeable flow entering the. canal.
It was supposed that the menhaden were clumped in the~ dilution bays because the water was stagnant and warmer.

Drive-along the south shore of Oyster Creek.
Ice formed along the shore and the small cove and 4 lagoons were frozen over except for the immediate vicinity of a freshwater drainage culvert in the blind end of Lagoon 3.
The cove beach was strewn with dead fish. A RMI representative and I estimated several thousand. We saw 3 small blue-j fish, the other were all menhaden ranging in size from 4'to 14 inches.
We measure 100 at random. The fork length frequency distribution is

9:00 A.M.
Proceeded along the south shore of Oyster Creek.
Lagoon 1 and 2 frozen over, Lagoon 3 frozen except in blind end near culvert.
Lagoon 4 was ice free in the blind end with dead menhaden floating and some distressed menhaden swimming eratically in the open water.
9:30 A.M.
Walked along Barnegat Bay and along the south shore of the Creek.
Saw 6 or 8 dead menhaden in the shallow water along_the bay-l shore, and several along the bank of the Creek near the entrance.
.
10:15 A.M.
Returned to Lagoon 4 and two men with a pickup truck were dipping and bagging the dead menhaden. They said they had 8 bags of about a bushel each and there were about 2 or 3 more in the water.
11:25 A.M.
In boat near mouth of Oyster Creek near Buoy No. 6; 320F 6 inches from top and 32-1/2 on the bottom.

Went back to Highway 9 bridge and met N. J. biologist and sh44 two assistants.
33 top and 32-1/20 on the bottom.
Proceeded in RMI boat to Barnegat Bay.
Biologist and crew launched 18-foot Boston Whaler with 20-f t. trawl aboard in Barnegat Bay and proceeded into Oyster Creek.
We accompanied them in RMI boat and observed four 5 to 10 minute trawls in the vicinity of Briarwood and Sand Point Marinas.
They had quite a bit of trouble with snags.
They caught little or nothing that we could see by watching them haul in the trawl.
They trawled several more times to the east off the Lagoon entrances and in Lagoon 1 and 3.
These were not observed but they reported that they got little or nothing except in Lagoon 3 where they got about a bushel of menhaden, a couple striped bass and several spot.
The fish were alive but sluggish. The striped bass were in poor condition with fin rot, opalescent eyes and abraded skin.
They trawled the length of Lagoon 4, setting their trawl about 100 feet outward of the blind end.
They caught about a bushel of menhaden and I noticed one striped bass and several spot. All appeared alive but sluggish.
In all, approximately 10 trawling station were made.
Except for the catches in Lagoon 3 and 4, few or no dead fish were taken.

technicians were walking along the shoreline counting and identify-ing dead fish. Representatives from Ichthyological Associates, Absecon, N. J. arrived and did some seining in several slips along the Marinas.
4:30 P.M.
N. J. biologists went up the discharge canal with boat and haul net.
They said it was a new device and were trying it out.
The net had a square fixed opening and was set in the middle of the canal from the boat and pulled ashore. During two tows observed, nothing was caught.

January 15 -
7:30 A.M.
Checked beach cove and 4 lagoons.
Ice covered cove and Lagoon 2.
Lagoon 1 was open in the center from yesterday's trawling.
Lagoon 3 was open with no dead fish, no surface signs nor any gulls. Lagoon 4
-
had about a hundred gulls working over the surface which was occasionally
'
broken by distressed menhaden.
From the signs there appeared to be at least several hundred menhaden in the lagoon. A few dead menhaden were floating in the blind end, apparently remaining from yesterday's kill.
.
f44#1 Conclusions l'
l The fish kill commenced about 7:00 A.M. on January 12 when the Highway 9 bridge temperature dropped below 40 F.
A few hundred menhaden and 25 to
30 bluefish were picked up or seen along the banks of the discharge canal and Creek by 10:00 A.M.
Some distressed and dying fish were seen during the remainder of the day.
I At 9:00 A.M. on January 13, menhaden and occasional bluefish were dead along the south shore of Oyster Creek.
The only sizeable concentration was in the cove just west of Lagoon 1.
An estimation of several thousand dead menhaden and 3 bluefish were made.
The size range and frequency dis-tribution would suggest that the population in the area was made up of all age groups.
Because menhaden school by size, the wide range of sizes suggest that no large, uniform population of menhaden were overwintering
-
in the area.
a On January 19, the only other concentration of dead menhaden was found in E
the blind end of Lagoon 4.
Approximately 10 bushels were picked up leaving only a few dead along the shore or visible on the bottom. From these obser-vations I would conclude that the apparent kill through Monday night amounted to approximately 10,000 fish. Of these 99 percent were Atlantic menhaden.
From the thermograph records and limited temperatures made,in
