Some dry waste is packaged on-site in boxes and shipped directly to low level radioactive waste (LLRW) disposal -currently Clive, Utah (200 to 300 ft 3/yr). Typically, one large container (200 ft 3) of Class A resin is packaged on-site every one to two years and shipped in a cask to a LLRW disposal site as noted above.Class B and C Diablo Canyon Power Plant (DCPP) currently stores Class B and Consite.DCPP has three 88 ft 3 containers of Class C cement encapsulated cartridge filters and two 98 ft 3 containers of polymer solidified Class B/C resin in the DCPP Radwaste Storage Building.

The building can hold 180 such containers.

DCPP's generation rate for Class B and C is projected to be two containers per year (one of filters and one of resin). Should the newly licensed site in Texas open to DCPP, shipments of Class B and C packages for disposal would resume. Shipments may be constrained by leased shipping cask availability (only six Type B casks for the entire USA) and budget.

Assembly Bill 292 states "The maximum annual amount available for disbursement for local costs, subject to subdivisions (e) and (f), shall, for the fiscal year beginning July 1, 2009, be one million seven hundred thirty-two thousand dollars ($1,732,000) for the Diablo Canyon site and one million six hundred thousand dollars ($1,600,000) for the San Onofre site." This legislation also has a formula of California Price index or prevailing wage paid to the County as an escalator clause. The entire legislation can be found at: http://info.sen.ca.gov/pub/07-08/bill/asm/ab 0251-0300/ab 292 bill 20071011 chaptered.html In addition to the sum outlined in Assembly Bill 292, below is a listing of entities that PG&E has letters of agreement with and the monetary support provided to each of them. Please note that French Hospital and Marian Hospital do not get this funding in the same year. They rotate participation in drills and exercises and are provided the funding in the year that they participate.

This is also true for San Luis Ambulance and American Medical Response.French Hospital Medical Center $12,500 Marian Medical Center $12,500 American Medical Response $ 5,000 San Luis Ambulance Service $ 5,000 American Red Cross (ARC) $15,000 American Red CrossNOAD 1 $ 5,000 Total 2 $37,500/year 1 Money goes to the Voluntary Organizations Active in Disaster (VOAD) entities that participate in the siren test. ARC is the organizer and distributor of funds for that event.2 French Hospital/Marian Medical Center and San Luis Ambulance/American Medical Response do not get funding in the same year.

Enclosure 1 PG&E Letter DCL-10-081 Sheet 16 of 23 In addition to funding from Diablo Canyon Power Plant to the nonprofit community to perform contractual work to enhance the effectiveness of the emergency plan, PG&E makes philanthropic donations to key nonprofits to further support emergency preparedness and life saving programs that would be called upon for any major disaster.

Specifically, in San Luis Obispo County PG&E has focused on two initiatives that are also supported by the County Office of Emergency services.

They are the 211 program, now hosted by the United Way, and Voluntary Organizations Active in Disaster (VOAD); a county wide collaboration amongst the nonprofit community, hosted by the American Red Cross.Each program is designed to complement emergency services provided by public agency emergency responders.

In short, their mission should direct community members to important services that are needed during emergencies but are not appropriate uses of the 911 system. Additionally, both the VOAD and 211 missions raise emergency preparedness awareness through the collective memberships of the nonprofit community, touching thousands of county residents.

Listed below are the donations made by PG&E to these programs.211 Program Donations:

PG&E provides the following sample 20-year window to demonstrate the incremental impact that continued investment in DCPP would have on property taxes, assuming the DCPP operating licenses berenewed and PG&E decides to operate the plant during the renewed period. PG&E estimates the capital spending at DCPP at approximately

$3.2 billion from 2010 to 2029 inclusive, should the operating license be renewed (See table provided below). PG&E forecasts the net impact of DCPP capital additions on tax payments to be approximately

$282.3 million over this same 20-year period (See table on Sheet 18). This is in addition to the normal property taxes that PG&E pays. Beyond this 20-year period, property taxes will continue to vary depending upon future capital additions and the Board of Equalization taxation formula.Decreases in property taxes would occur at a future point in time when DCPP is approaching decommission and capital investment declines.2010 to 2029 DCPP Capital Addition Year Capital Addition (In Thousands of Dollars Nominal)2010 195,518 2011 165,255 2012 183,849 2013 156,468 2014 182,095 2015 154,618 2016 117,357 2017 176,096 2018 220,733 2019 151,066 2020 128,242 2021 175,600 2022 179,463 2023 136,894 2024 139,906 2025 142,984 2026 146,129 2027 149,344 2028 152,630 2029 155,988 Total 3,210,234 Enclosure 1 PG&E Letter DCL-10-081 Sheet 18 of 23 I 201 Net Plant -Capital Addition 195,518 Composite Property Tax Facl 1.176420°Estimated PG&E Property Estimated Property Tax Impact of DCPP Net Plant 2010-2029 (In Thousands of Dollars)01 20111 20121 20131 20141 20151 20161 2 346,807 503,979 618,448 744,321 824,507 850,251 930,(lo 1.196739%

The vans normally operate four days per week to match DCPP workers four days per week -ten hours per day work schedule.

The vanpooling is available to PG&E, long term contractor, and refueling outage temporary personnel.

During refueling outages the vans may operate five or six days per week to accommodate additional worker transportation needs and help to mitigate parking shortages at DCPP. The following table provides information on departure locations, stops, and times.Departure Location & Time Stop Location(s)

Enclosure 1 PG&E Letter DCL-10-081 Sheet 22 of 23 Audit Question 17 Provide a copy of 97-03-DWQ National Pollutant Discharge Elimination System General Permit.PG&E Response 17 Water Quality Order No. 97-03-DWQ National Pollutant Discharge Elimination System (NPDES) General Permit No. CAS000001 (General Permit) "Waste Discharge Requirement (WDRS) for Discharges of Storm Water Associated with Industrial Activities Excluding Construction Activities" is not a permit specific to the Diablo Canyon Power Plant (DCPP) facility.

The General Permit is implemented statewide by the California State Water Resources Control Board (SWRCB), and is intended to apply to those industrial facilities that do not have site specific permits, which incorporate or address storm water discharges.

Order No. 97-03-DWQ was/is not issued directly to industrial facilities, and therefore DCPP does not maintain a formal site specific copy. The General Permit may periodically be modified, updated, or replaced in entirety by the State. The most current version of the General Permit is maintained by, and available directly from, the SWRCB.Industrial facilities complete and file a Notice of Intent (NOI) to enroll in the General Storm Water Permit Program. Once an NOI is filed, a facility is registered in the program and provided a site specific Identification Number (ID), required to pay an annual program fee, and expected to implement the current provisions of the General Permit including completion and submittal of an annual report.The current DCPP NPDES Industrial.

Waste Water Discharge Permit No. CA0003751, Order 90-09 incorporates site storm water discharges.

PG&E submitted an NOI to enter the State Industrial Storm Water General Permit Program in July 2, 2003, in anticipation of renewal of the NPDES Industrial Waste Water Discharge Permit. The renewed permit would not have incorporated stormwater discharges, and therefore, participation in the Storm Water General Permit Program would have subsequently been appropriate.

However, the NPDES Industrial Waste Water Discharge Permit was not renewed in July of 2003. The California Regional Water Quality Control Board Central Coast Region (CRWQCB) then issued a letter indicating that DCPP's storm water would continue to be covered under the existing Order 90-09 until a revised NPDES permit was adopted.Due to ongoing delay of renewal of the NPDES Industrial Waste Water Discharge Permit, PG&E voluntarily agreed to conditionally implement provisions of the State Industrial Storm Water General Permit Program in November of 2006.
