Ichthyological Associates, Inc. (IA) was notified.

' 1A is th'e company's ecological consultant, currently performing the on-site impingement monitoring.

The s,r

. was identified as a Loggerhead sea turtle, and on Sept %uber 8 through 11, 1981, the following agencies were notified concerning the occurrence:

National Marine Fisheries

~

Service, U.S.

Environmental Protection Agency Region II, U.S.

Nuclear Regulatory Commission, U.S. Fish and Wildlife Service, New Jersey Department of Environmental Protection, and the Delaware Department of Natural Resources and.Envi-ronmental Control.

The specimen, at the direction of the National Marine Fisheries Service, was given to the Marine Matamal Stranding Center, Atlantic City, New Jersey, for autopsy and further testing.

The autopsy indicated that the turtle was a female about two years short of sexual maturity.

It had died of peritonitis.

The intestine had been perforated I

by a blue crab claw.

The turtle's gut was also filled with l

pieces of crab shells.

The specimen had a carapace width of 510 mm, a carapice length of 575 mm, and weighed approximately 80 to 100 pounds.

The specimen had a carapace length of 523 millimeters and a carapace width of 431 millimeters.

The weight was not taken because it exceeded the balances load factor.

Starting on September 18, 1981, the following agencies were contacted:

The National Marine Fisheries Service, the U.S.

Environmental Protection Agency, U.S.

Nuclear Regulatory Commis-

sion, U.S. Fish and Wildlife Service, New Jersey Department of Environmental Protection, and the Delaware Department of Natural Resources and Environmental Control.

At the direction of the National Marine Fisheries Service, the specimen was also turned over to the Marine Mammal Stranding Center for autopsy and further testing.

The time of death could not be determined.

On September 23, 1981 at 1000 hou:s, a Ridley sea turtle was removed from the intake trash bars by station personnel.

IA was notified. The specimen had a carapace length of 325 mm and width of 290 mm.

At the direction of the National Marine Fisheries Service, the specimen was turned over to the Marine Mammal Stranding Center for autopsy and further testing.

The autopsy results have not been received to date.

DESIGNATION OF APPARENT CAUSE OF OCCURREI '{E_:

Sea turtles have been occurring with increased frequency in the Delaware estuary in the past several months.

Their occurrence is being studied by the Marine Mammal Stranding Center.

The turtles exhibit little fear in their search for food and mates.

Turt les may come into contact with the CWS intake and find the available food supply sufficient to pro-long their stay in the area.

Individuals stressed due to other causes may become impinged on the trash bars and could potentially drown.

Healthy individuals should be able to avoid the intake structure.

ANALYSIS OF OCCURRENCE:

The Salem CWS travelling screens remove approximately 6,000 tons of detritus per year from the Delaware River.

This

{

material is returned to the river.

In aadition, a large but unknown quantity of detritus is removed from the trash bars and subsequently landfilled.

A dead turtle or one in weakened condition near the CWS intake, dependant on tidal conditions, could be drawn on to the intake structure and become part of tale detrital leading.

CORRECTIVE ACTION

The trash bars will be observed and cleaned when necessary.
