==Dear Mr. Cordaro:==
Enclosed is a National Marine Fisheries Service (NMFS) Marine Mammal and Marine Turtle Stranding Report for a sea turtle discovered in the Diablo Canyon Power Plant (DCPP) intake structure.
A live sea turtle was discovered in the 2-7 intake structure forebay by plant operations personnel at approximately 9:50 p.m. on August 08, 2010. The turtle was identified as a green sea turtle (Chelonia mydas).As authorized in DCPP's incidental take statement issued September'18, 2006, DCPP staff removed the turtle from the intake structure early the following morning (August 09, 2010) for release offshore of the Facility.
The turtle was removed by salmon net and transported to a boat. The plant biologist completed measurements of the specimen and photographs were taken. The photographs are enclosed in addition to the stranding report. The turtle was estimated to weigh 25 pounds, with a shell length (notch-tip) of 20 and 7/8 inches, and appeared to be in good health based on visual observation.
There were no abrasions or indication of any injury. The turtle was tagged on the right front flipper with tag #MC-24, and subsequently transported by boat and released in the ocean approximately two miles southwest of DCPP. The turtle swam away strongly in a southerly direction following release.Discovery and release of the turtle was reported to NMFS on September 09, 2010, within the required 48-hour reporting period.Live green sea turtles have been discovered at DCPP's intake on nine previous occasions during commercial operations:
September 08, 2009, July 23, 2007, February 27, 2001, April 16, 2000, August 24, 1999, May 29, 1999, June 12, 1997, January 10, 1997, and April 27, 1994. Green sea turtles are infrequently observed in the coastal waters off of DCPP..COPY PG&E Letter DCL-2010-536 Joseph G.
