Dear Commissioners and Staff:

Pacific Gas and Electric Company (PG&E) is submitting the Decommissioning Funding Report for Humboldt Bay Power Plant (HBPP) Unit 3, pursuant to the requirements of 10 CFR 50.75(f).

Humboldt Bay Unit 3 At the end of calendar year 2007, the market value of the HBPP Unit 3 (220 MWt) decommissioning trust funds was 316.8 million dollars. PG&E estimates an additional 35.745 million dollars (future nominal dollars) will need to be collected over 3 years beginning in 2007 to coincide with decommissioning of HBPP Unit 3 beginning in 2009 based on a site-specific decommissioning cost estimate prepared by TLG Services, Inc., and adjusted per the Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) Decision 07-01-003 from the California Public Utilities Commission (CPUC). The CPUC Decision was based on an Independent Spent Fuel Storage Installation (ISFSI) being constructed at HBPP that would be in operation until 2015 when all fuel would be removed from HBPP by the Department of Energy.

The market value of the HBPP trust is lower than the minimum amount of the NRC decommissioning estimate of 590.9 million dollars (2008 dollars) that was calculated pursuant to the requirements specified in 10 CFR 50.75(c), which is based on a minimum 1200 MWt plant.

PG&E is confident the HBPP trust, with the noted additional contributions, will be sufficient to ensure successful decommissioning beginning in 2009, and maintaining the spent fuel in an ISFSI at HBPP until 2015, based on a site-specific decommissioning cost estimate prepared by TLG Services, Inc. and the CPUC Decision 07-01-003.

Document Control Desk PG&E Letter HBL-08-007 March 31, 2008 Page 2 Supporting Cost Estimates Based on site-specific cost estimates prepared by TLG Services, Inc., and adjustments as a result of the NDCTP Decision 07-01-003, PG&E has estimated that the decommissioning costs are approximately 369.7 million dollars (including 24.5 million dollars disbursed from the Trust[s] through December 2007, and 345.2 million dollars future radiological removal costs) for HBPP Unit 3 in 2008 dollars. These costs do not include site restoration of the facilities (6.5 million dollars) nor spent fuel management until 2015 (86.9 million dollars).

To assure that sufficient funds will be available for decommissioning, PG&E has established external sinking trust fund accounts for HBPP Unit 3.

Supporting Enclosures Supporting documentation for this Report is included as Enclosures 1 through 4. provides decommissioning funding status information in a format suggested by Nuclear Energy Institute (NEI) and the NRC. provides information on the escalation of the required decommissioning funding amounts from 1986 dollars to 2008 dollars. As required by 10 CFR 50.75(c)(2), and using NUREG-1577, "Standard Review Plan on Power Reactor Licensee Financial Qualifications and Decommissioning Funding Assurance," Revision 1, and NUREG-1307, "Report on Waste Burial Charges,"

Revision 12, the information includes escalation factors for energy, labor, and waste burial costs. is Appendix D from the TLG Services, Inc. Decommissioning Cost Estimate Report prepared in October 2005 for PG&E for HBPP Unit 3. The TLG Services, Inc. cost estimate has then been adjusted to reflect the costs in 2008 dollars per CPUC Decision 07-01-003 by applying the escalation factors; adjusting the burial costs of Class A Low Level Radioactive Waste from 140 dollars per cubic foot to 248 dollars per cubic foot; and revising the contingency to 25 percent. The report provides cost estimates for decommissioning of both the nuclear and non-nuclear facilities, including the ISFSI. is a cash flow of the total decommissioning of HBPP that identifies the monies for NRC scope (removal of radiological contamination), site restoration (including the nonradiological work), and the spent fuel management.

Previous submittals have included the TLG Services, Inc Decommissioning Cost Estimate Report prepared in October 2005 for PG&E for the HBPP Unit 3. This report provided in HBL-07-002, "Decommissioning Funding Report for Humboldt

Document Control Desk PG&E Letter HBL-08-007 March 31, 2008 Page 3 Bay Power Plant Unit 3," has not changed, therefore PG&E is not including the report in this submittal. Should the NRC need a copy of this report, please contact Bob Kapus at (707) 444-0810.

There are no regulatory commitments in this letter.

PG&E Letter HBL-08-007 NRC Decommissioning Funding Status Report Humboldt Bay Power Plant - Unit 3 (220 MWt)

As provided in 10 CFR 50.75(f)(1), each power reactor licensee is required to report to the NRC on a calendar year basis, beginning March 31, 1999, and annually thereafter, on the status of its decommissioning funding for each reactor that it owns and has already closed.

$ in Millions

1. The minimum decommissioning fund estimate, pursuant to 10 CFR 50.75 (b) and (c).1 January 2008 dollars

$ 590.9 (HBPP is a shutdown unit with a Site Specific Cost Study; therefore, the minimum decommissioning fund estimate is based on the Site Specific Cost Study shown in item 8 of this enclosure.)

2. The amount accumulated at the end of the calendar year preceding the date of the report for items included in 10 CFR 50.75 (b) and (c). (Alternatively, the total amount accumulated at the end of the calendar year preceding the date of the report can be reported here if the cover letter transmitting the report provides the total estimate and indicates what portion of that estimate is for items not included in 10 CFR 50.75 (b) and (c)).

3. A schedule of the annual amounts remaining to be collected; for items in 10 CFR 50.75 (b) and (c). (Alternatively, the annual amounts remaining to be collected can include items beyond those required in 10 CFR 50.75 (b) and (c) if the cover letter transmitting the report provides a total cost estimate and indicates what portion of that estimate is for items that are not included in 10 CFR 50.75 (b) and (c). (See item 6 of this enclosure describing the collection of additional funds.)

• The NRC formulas in section 10CFR50.75(c) include only those decommissioning costs incurred by licensees to remove a facility or site safely from service and reduce residual radioactivity to levels that permit: (1) release of the property for unrestricted use and termination of the license; or (2) release of the property under restricted conditions and termination of the license. The cost of dismantling or demolishing non-radiological systems and structures is not included in the NRC decommissioning cost estimates. The costs of managing and storing spent fuel on site until transfers to DOE are not included in the cost formulas.
