IMPORTANT ENVIRONMENTAL EVENT
"The following is being reported in accordance with the Diablo Canyon Power Plant (DCPP) Environmental Protection Plan (EPP) section 4.1 as an 'unusual or important environmental event' requiring NRC notification within 24-hours:
"During diving operations to clean the intake bar racks, the diver discovered 50 to 100 dead Cormorants. Cormorants are diving sea birds and are common in the DCPP intake cove. They have recently started nesting in larger numbers on a large rock at the southern end of the intake cove, and feed in the intake cove.
"The event did not impact plant operations. It is believed that the birds died of natural causes and collected on the bar racks due to the water currents. To help determine the cause of death, some birds are being saved for testing and analysis.
"DCPP will submit a written report within 30 days in accordance with section 5.4.2 of the EPP."
The licensee notified the NRC Resident Inspector.

LOSS OF ERDADS COMMUNICATION
"On 08/15/2006 during performance of the quarterly ERDADS functional communications test, the ERDADS communication link from the U1 Control Room to the NRC Operations Center was determined to be unavailable. Initial notification was made to the NRC Operations Center and the communications vendor was contacted to investigate the source of the problem. Subsequent notification was made by the vendor to the Site identifying that the communications failure was occurring within the portion of the system under control of the Site. Troubleshooting by the Site is in progress. Note: the U2 ERDADS communication link tested satisfactory. This non emergency notification is being made pursuant to 10 CFR 50.72(b)(3)(xiii) regarding loss of communications capability."
