Executive Officer California Regional Water Quality Control Board Central Coast Region 895 Aerovista, Suite #101 San Luis Obispo, CA 93401-7906 Storm Water Management at Pacific Gas & Electric Company (PG&E) Diablo Canyon Power Plant (DCPP)

Dear Mr. Briggs:

On October 11 "h2006, PG&E met with Peter von Langen, David Innis, Jennifer Bitting, and IaVid Schwartzbart of your staff to discuss DCPP's storm water management program. PG&E's current NPDES permit (No. CA000375 l/Order 90-09) contains storm water discharge requirements and describes DCPP site outfalls specific to storm water runoff. In anticipation of NPDES permit renewal in 2003, DCPP submitted a Notice of Intent (NOI) to the State Water Resources Control Board to obtain coverage for site storm water discharges under the State General Industrial Storm Water Permit (General Permit). However, the NPDES permit was not renewed, and the Regional Board issued a letter on July 30, 2003 indicating that DCPP's storm water would continue to be covered under the existing Order 90-09 until a revised NPDES permit is adopted.

With the ongoing delay in NPDES permit renewal, DCPP has continued to make efforts to improve its storm water management program, following the requirements of the State's General Permit program. At our October 11"' meeting, DCPP staff, in coordination with your staff, agreed to the following:

1) Effective as of October 120 2006, implement monitoring for industrial site storm water discharges in accordance with General Permit requirements. DCPP will "visually observe and collect samples of storm water from all drainage areas that represent the quality and quantity of the facility's storm water discharges" and perform sample analysis in accordance with General Permit Section B.5.c.

subparts i-iii.

2) Complete a written site Storm Water Pollution Prevention Plan (SWPPP), and implement the plan effective December 15th 2006.

3) Submit an Annual Report for Industrial Storm Water Discharges commencing with the 2006-2007 reporting period due July 1 t 2007.

4) During the ongoing period prior to adoption of a revised NPDES Permit for DCPP (and termination of existing Order 90-09), in the event a conflict arises between Order 90-09 and the provisions of the General Permit, DCPP shall defer to the directives of Order 90-09.
