Enclosure PG&E Letter DCL 02-052 2001 ANNUAL NONRADIOLOGICAL ENVIRONMENTAL OPERATING REPORT DIABLO CANYON POWER PLANT Pacific Gas And Electric Company April 2002
Enclosure PG&E Letter DCL 02-052
- 1. Introduction PG&E has prepared the 2001 Annual Nonradiological Environmental Operating Report (AEOR) in accordance with the Environmental Protection Plan (EPP), Appendix B of Facility Operating Licenses DPR-80 and DPR-82 for Diablo Canyon Power Plant (DCPP), Units 1 and 2. The report describes implementation of the EPP per the routine reporting requirements of EPP Subsection 5.4.1. PG&E remains committed to minimizing the environmental impact of operating DCPP.
- 2. Environmental Monitoring 2.1 Aquatic Issues Aquatic issues are addressed by the effluent limitations and receiving water monitoring/reporting requirements contained in the DCPP National Pollutant Discharge Elimination System (NPDES) permit. The NPDES permit includes applicable requirements of the State Water Resources Control Board's Ocean Plan and Thermal Plan.
2.1.1 Routine Influent and Effluent Monitoring DCPP submitted quarterly NPDES reports containing routine influent and effluent monitoring data and permit compliance summaries to the Central Coast Regional Water Quality Control Board (CCRWQCB) by the 20th day of the month following the end of each quarter. DCPP also submitted an annual NPDES report to the CCRWQCB in February 2002.
The annual report contained monitoring data summaries in tabular and graphical form and a summary of permit compliance and corrective actions for 2001. Copies of the quarterly and annual reports were submitted concurrently to the NRC.
2.1.2 Receiving Water Monitoring Program The NPDES Receiving Water Monitoring Program, required by the CCRWQCB, included the ecological monitoring, temperature measurements, and State Mussel Watch activities.
Environmental monitoring programs have recorded biological changes in the discharge area since plant startup. These programs monitor intertidal and subtidal communities of invertebrates, algae, and fish in the discharge cove and at stations north and south of DCPP. During 2001, environmental monitoring continued under the revised Receiving Water Monitoring Program (RWMP). The revised RWMP continued historical monitoring tasks, including temperature monitoring, state mussel watch activities, and intertidal and subtidal surveys (with additional stations and increased sampling frequencies).

Enclosure PG&E Letter DCL 02-052 DCPP reached a tentative agreement with the CCRWQCB staff, in 2000, that addresses current and future impacts on the receiving waters. If the agreement is implemented, it will eliminate future receiving water monitoring requirements. Effluent monitoring will continue under the NPDES Permit.
DCPP submitted the "Receiving Water Monitoring Program - 2000 Annual Report" (PG&E letter DCL-2001-535) to the CCRWQCB and the NRC on April 30, 2001.
2.1.3 Thermal Effects Study DCPP submitted the final thermal effects comprehensive assessment report to the CCRWQCB and the NRC in 1998.
2.1.4 316(b) Studies DCPP submitted the final 316(b) report, entitled "Diablo Canyon Power Plant 316(b) Demonstration Report" (PG&E letter DCL-2000-514) to the CCRWQCB and the NRC, dated March 1, 2000.
2.2 Terrestrial Issues 2.2.1 Herbicide Application and Erosion Control PG&E continues to implement erosion control activities at the plant site and in the transmission line corridors as part of an overall land management program. These erosion control activities consist of routine maintenance and prevention efforts that are performed periodically on an as-needed basis, including seasonal storm damage repair and wildfire damage repair.
Herbicides are used as one component of an overall land management program that includes transmission line corridors and rights-of way. The company continues to use only EPA and/or state-approved herbicides and applies them in accordance with all applicable regulations.

Enclosure PG&E Letter DCL 02-052 2.2.2 Preservation of Archaeological Resources A. CA-SLO-2 Site Management All work performed within the boundaries of CA-SLO-2 is tracked and approved per plant procedure EVI.ID2, "Archeological Resources Management Plan (ARMP)."
In October, the PG&E archaeologist reviewed the 23 SLO-2 photo monitoring stations. The photo monitoring was conducted in accordance with the Archaeological Resource Management Plan. No new areas of erosion or impacts to SLO-2 were noted.
B. Chumash Indian Correspondence There was no communication between PG&E and the Northern Chumash Indians during 2001 concerning CA-SLO-2.
- 3. Unusual or Important Environmental Events No unusual or important events that would indicate, or could result in, a significant environmental impact causally related to station operations occurred in 2001.
4.2 Changes In Station Design There were no changes in plant design or operation, tests or experiments that involved an unreviewed environmental question or a change to the EPP.
4.3 Nonroutine Reports There were no nonroutine events during 2001 per the EPP; and therefore, no nonroutine reports were submitted to the NRC.
On March 14, 2001, a Green Sea Turtle was found at the intake structure. The turtle was removed and released offshore unharmed. Although the Endangered Species Act protects these turtles, there was no significant environmental impact caused by the plant. PG&E letter DCL-2001-520, dated March 14, 2001, was submitted by PG&E to the National Marine Fisheries Service regarding the removal and release of the turtle. A copy of this report was provided to the NRC.
