PacificGas and ElectricCompany James R. Becker Diablo Canyon Power Plant Site Vice President Mail Code 104/5/601 P 0. Box 56 Avila Beach, CA 93424 March 31, 2009 805.545.3462 Internal: 691.3462 Fax: 805.545.6445 PG&E Letter HBL-09-004 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 Docket No. 50-133, OP-DPR-7 Humboldt Bay Power Plant Unit 3 Decommissioning Funding Report for Humboldt Bay Power Plant Unit 3

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 2008, the market value of the HBPP Unit 3 (220 MWt) decommissioning trust funds was $331.1 million. PG&E estimates an additional

$35.745 million (future nominal dollars) will need to be collected over three 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 (DOE).

The market value of the HBPP trust is lower than the minimum amount of the NRC decommissioning estimate of $573.8 million (2009 dollars) that was calculated pursuant to the requirements specified in 10 CFR 50.75(c), which is based on a minimum 1200 MWt plant.

The site-specific decommissioning cost estimate prepared by TLG Services, Inc.,

and the CPUC Decision 07-01-003, indicated that the HBPP trust, with noted additional contributions, will be sufficient to ensure successful decommissioning. As required by regulation, PG&E will continue to submit these annual decommissioning funding assurance reports to the NRC that may reflect changes to decommissioning estimates based on future changing conditions.

Document Control Desk PG&E Letter HBL-09-004 March 31, 2009 Page 2 Supporting Cost Estimates Based on a site-specific cost estimate 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 $395.5 million (including $37.1 million disbursed from the Trust(s) through December 2008, and $358.4 million future radiological removal costs) for HBPP Unit 3 in 2009 dollars. These costs do not include site restoration of the facilities ($6.5 million), nor spent fuel management until 2015 ($83.8 million). PG&E is in the process of updating the site-specific cost estimate for HBPP Unit 3 for submittal to the CPUC in 2009. PG&E will provide an update of the 2009 site-specific decommissioning cost estimate to the NRC when approved by the CPUC.

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 the Nuclear Energy Institute and the NRC. provides information on the escalation of the required decommissioning funding amounts from 1986 dollars to 2009 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-1 307, "Report on Waste Burial Charges,"

Revision 13, 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 2009 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 per cubic foot to

$248 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 funding for NRC scope (removal of radiological contamination), site restoration (including the non-radiological work), and the spent fuel management.

Document Control Desk PG&E Letter HBL-09-004 March 31, 2009 Page 3 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 Bay Power Plant Unit 3," is still the cost estimate of record with the CPUC; therefore, PG&E is not including the report in this submittal. Should the NRC need a copy of this report, please contract Bob Kapus at (707) 444-0810.

There are no regulatory commitments in this letter.

Should you have any questions in regard to this document, please feel free to call Bob Kapus at the number listed above.

Enclosure 1 PG&E Letter HBL-09-004 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 2009 dollars $ 573.8 (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)).

Market Value (December 2008 dollars) $ 333.1

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.)

Amount remaining $35.745 1, 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 nonradiological systems and structures is not included in the NRC decommissioning cost estimates. The costs of managing and storing spent fuel onsite until transfers to the Department of Energy are not included in the cost formulas.
