SUBJECT:

HUMBOLDT BAY POWER PLANT, UNIT 3 - APPROVAL OF FINAL STATUS SURVEY REPORTS FOR SIX SURVEY AREAS WITHIN SURVEY UNIT OOL10

Dear Mr. Halpin:

By letter dated October 17, 2019 (ADAMS Accession No. ML19291A845), Pacific Gas and Electric Company (PG&E) submitted final status survey reports (FSSRs) for the Circulating Water Intake Piping Excavation Area (OOL 10-05), 60 kV Switchyard Excavation (OOL 10-06),

Remainder of Land Area (Parking Lot A) (OOL 10-14), Buhne Slough (OOL 10-15), Area East of Trailer City (OOL 10-19), and Humboldt Bay (OOL 10-23).

The staff has reviewed your FSSRs for OOL 10-05, OOL 10-06, OOL 10-14, OOL 10-15, OOL 10-19, and OOL 10-23, and the results presented are all a fraction of the Derived Concentration Guideline Limit. The gamma walkover scanning coverage described in the report was adequate. The survey and analyses for these survey units provided reasonable assurance that you can demonstrate compliance with the unrestricted release criteria in 10 Code of Federal Regulations (CFR) 20.1402, Radiological criteria for unrestricted use. Based on our review of the survey results, survey units OOL 10-05, OOL 10-06, OOL 10-14, OOL 10-15, OOL 10-19, and OOL 10-23, are acceptable to support release of those areas for unrestricted use.

Further details on our review are provided in the enclosed safety evaluation.

In accordance with Title 10 CFR 2.390 of the NRCs Rules of Practice for Domestic Licensing Proceedings and Issuance of Orders, a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records component of NRCs ADAMS.
