FACILITY:
IMPINGEMENT OF SEA TURTLES September 20, 1989 August JO, 1989 and September 5, 1989 Salem Generating Station, Units 1 and 2 Public Service Electric and Gas Company Hancocks Bridge, NJ 080J8 IDENTIFICATION OF OCCURRENCES:
One Kemp's Ridley (Lepidochely's kempi) sea turtle was impinged on the Circulating Water System (CWS) intake trash bars at Salem Generating Station on August JO, 1989 and a second Kemp's Ridley impinged on September 5, 1989.
The Kemp's Ridley is federally listed as an "endangered" species under the Endangered Species Act of 1973, as amended.
CONDITIONS PRIOR TO OCCURRENCES:
August 30, 1989 -
Unit 1, 100 percent power Unit 2, 100 percent power September 5, 1989 - Unit 1, 100 percent power Unit 2, 100 percent power DESCRIPTION OF OCCURRENCES:
on August JO, 1989 at 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br />, one Kemp's Ridley sea turtle was reported on the trash bars of the CWS intake.
Both units were at full power at the time the turtle was found.
The turtle was recovered during the cleaning of the trash racks by the on-duty intake operator.
The Senior Shift Supervisor, Licensing and Regulation personnel, and the Marine Maminal Stranding Center (MMSC) of Brigantine, New Jersey were immediately notified.
The turtle was then brought to the MMSC were it was fed and maintained until September 7, 1989, when it was released.
The turtle had a carapace length of 21 cm and weighed 5 lb. 1 oz. at the time it was brought to the MMSC.
It weighed 5 lb. 10 oz. at the time of its release offshore of Moores Beach, NJ.
on September 5, 1989, at 09JO a dead Kemp's Ridley sea turtle was recovered from the trash bars.
Both units were at full power at the time the turtle was found.
The Senior Shift Supervisor, Licensing and Regulation personnel, and the Marine Mammal Stranding Center (MMSC) of Brigantine, New Jersey were immediately notified.
The turtle was packed in ice and sent to the MMSC where a necropsy was performed.
The cause of death was determined to be suffocation as a result of impingement.
It was determined that the turtle was healthy prior to impingement.
It's carapace length was 17 cm and weight was J lbs. J oz.
The following agencies have been notified regarding these occurrences:
U.S. Nuclear Regulatory Commission U.S. National Marine Fisheries Service New Jersey Department of Environmental Protection APPARENT CAUSE OF OCCURRENCES:
Sea turtles are summer migrant, common to Delaware Bay.
Small numbers typically occur in the lower Delaware River near Salem during July through September.
Past experience indicates that healthy sea turtles are usually able to avoid the approach velocity of the CWS intake.
The turtle impinged on September 5 may not have been able to escape the approach velocity due to its small size, and was therefore trappedo Some turtle mortalities are also attributed to animals which are injured by boats or commercial fishing operations, and then float into the area of the circulating water intake.
ANALYSIS OF OCCURRENCE:
The CWS intake is monitored for accumulation of debris, which is periodically removed.
Any turtles which are observed in the area of the trash bars are recovered immediately.
Between 1979 and present, a total of 48 sea turtles have been collected at or in the immediate vicinity of the plant.
Of the forty-two turtles collected at the intake, twenty-eight (67%) were loggerhead sea turtles and fourteen (33%) were Kemp's ridley sea turtles.
CORRECTIVE ACTION:
The trash bars are observed at least once per eight hour shift and cleaned at least once per day.
Any sea turtle observed on the trash bars is removed immediatelyo Resuscitation will be attempted if the turtle is not unquestionably dead.
In accordance with standard procedure, all specimens will be held under appropriate conditions and turned over to the MMSC.
