Enclosure PG&E Letter DCL-09-028
- 1. Introduction Pacific Gas and Electric Company (PG&E) prepared the 2008 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 During 2008, 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) during the month following the end of each quarter. DCPP also submitted an annual NPDES report to the CCRWQCB in February 2009. The annual report contained monitoring data summaries in tabular and graphical form, and a summary of permit compliance and corrective actions for 2008.
Copies of the quarterly and annual reports were submitted concurrently to the Nuclear Regulatory Commission (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 start-up. 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 2008, 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 1

The NPDES permit remains under administrative extension. In 2000, DCPP reached a tentative agreement with CCRWQCB'staff, which addressed current and future impacts on receiving waters from power plant effluent discharge. This agreement, and the revised NPDES permit renewal application, did not receive the expected approvals from the CCRWQCB in July 2003, and discussions are continuing with CCRWQCB staff and their consultants. Based on the tentative agreement, future receiving water monitoring requirements will be significantly reduced or eliminated upon approval of the revised NPDES permit. Effluent monitoring will continue under the revised NPDES Permit.
PG&E submitted Letter DCL-2008-518, "Receiving Water Monitoring Program - 2007 Annual Report," dated April 25, 2008, to the CCRWQCB and the NRC. The 2008 Receiving Water Monitoring annual report will be submitted via DCL-2009-517, during April 2009.
2.1.3. Thermal Effects Study PG&E submitted the final thermal effects comprehensive assessment report to the CCRWQCB and the NRC in 1998.
2.1.4. 316(b) Studies PG&E submitted the final 316(b) report to the CCRWQCB and the NRC via DCL-2000-514, "316(b) Demonstration Report," dated March 1, 2000.
2.2. Terrestrial Issues 2.2.1.
Herbicide Application and Erosion Control 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.
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 performed periodically on an as-needed basis, including seasonal storm damage repair and wildfire damage repair.

Enclosure PG&E Letter DCL-09-028 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 DCPP Procedure EV1.ID2.
In November 2008, PG&E's cultural resources specialist reviewed the 23 SLO-2 photo-monitoring stations. Photo monitoring was conducted in accordance with the Building and Land Service Department's (now Corporate Real Estate), "Cultural Resources Management Procedures for Archaeological Site CA-SLO-2," which implements policies of the Archaeological Resource Management Plan. One area with potential erosion issues was noted. PG&E is working with an erosion control expert to address this impact to SLO-2. No other impacts to SLO-2 were noted during this visit.
B. Chumash Indian Correspondence In 2008 there were no request for access to visit SLO-2. PG&E only had contact with the Chumash in regards to projects on the North Ranch and not in the vicinity of SLO-2.
- 3. Unusual or Important Environmental Events There were no unusual or important environmental events during 2008.
- 4. Plant Reporting Requirements 4.1. EPP Noncompliance There were no EPP noncompliances during 2008.
4.2. Changes In Station Design There were no changes in plant design, 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 2008 per the EPP, and therefore no nonroutine reports were submitted to the NRC.
