APPARENT CAUSE OF OCCURRENCES Sea turtles are a summer migrant, common to Delaware Bay.
Small numbers typically occur in the lower Delaware River near Salem during July through September.
Past exp~rience indicates that healthy sea turtles are usually able to avoid the approach velocity of the CWS intake, although occassionally one will become impinged on the trash bars.
ANALYSIS OF OCCURRENCE The CWS intake is monitored for the accumulation of debris, which is periodically removed.
Any turtles which are observed impinged against the trash bars are recovered immediately.
Between 1979 and present, a total of 28 sea turtles have been collected at or in the immediate vicinity of the plant.
Of these, eight (29%)
were Kemp's Ridleys and 20 (71%) were loggerheads.
Of the total turtles collected, 10 (36%) were alive when recovered.
CORRECTIVE ACTION The trash bars are observed at least once per 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> shift and cleaned at least once per day.
Any sea turtle observed on the trash bars is removed immediately.
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 Marine Mammal Stranding Center.
