Dear Commissioners and Staff:
In accordance with Humboldt Bay Power Plant Unit 3 (HBPP) Ucense Condition 2.C.(5), Pacific Gas and Electric Company (PG&E) is notifying the NRC at least 14 days prior to implementation of reclassilfication of a survey area to a less restrictive classification. PG&E intends to redassify Building 47 (Waste Management Facility (WMF)) and the WMF Storage Pad as depicted in Figure 2-2 of the Defueled Safety Anallysis Report and described in Section 2 .1.8.17 of the License Termination Plan (LTP} from a Multi-Agency Radiation Survey and Site Investigation Manual Class 1 to lower classifica1lions as described below.The WMF was built during decommlssioning and was classified as a Class 1 area based on the expected decommissioning support activities to be conducted in the area. However, a subsequent decision to direct most of the radiological reme<Jiation waste to new soil management structures reduced the anticjpated radiological impact on the WMF. The current classification as indicated by LTP Section 2.1.8 .1 7 is a Class 1 survey area.Visual inspections performed of the areas behind the push walls , which are too small for a person to enter, indicate minimal amounts of spoils and decommissioning debris present. A characterization survey was performed June 6, 2019, to assess the radiological impact to the facility from past operations. The survey focused on the limited access areas behind the soutt, push wall of the structure. Direct measurements collected from the structure wall, push wa ll, and floor where residual material was sampled indicate less than 1 percent of the building surface Derived Concentration Guideline Level (DCGL) for Cs-1 37. Media samples of spolls, splatter, and debris material collected from the areas prior to direct measurement collection averaged less than 1 percent of the soil DCGL for Cs,..137. It should be noted that of all 15 media samples collected , only one indicated Gs-137, a:n HBPP plant-derived radionuclide , with a result of 3.24E-01 pCl/g. This result ts indicative of global fallout concentrations observed for the area.

ÿ9ÿ 4ÿ8 Document Control Desk PG&E l etter HBL- 19-012 July 11, 2019 Page2 The WMF will be deaned prior to final status survey (FSS) and then reconfigured as a warehouse facility for the Humboldt Bay Generating Station.
PG&E proposes to perform a survey to the rigors of a Class 2 survey area on accessible concrete surfaces of the floor and walls. The accessible and limited accessible areas within and behind the push wall respectively have the highest potential for contamination; therefore, activity levels should be similar to or greater than the inaccessible areas behind the push wa'lls. However, static measurements of the inaccessible areas behind the push wall will be collected for statistical comparisons with data collected from the accessible areas behind the push wall as part of the Data Quality Objective process for FSS Survey Design.PG&E also proposes a survey to the rigors of a Class 2 survey area on the remainder of the area surrounding the WMF, known as the WMF Storage Pad. The downgrading of the WMF Storage Pad from a Class 1 to a Class 2 survey unit is reasonable and appropriate given the above history and the absence of activity distinguishable from background from review of routine contamination surveys performed of this area.PG&E proposes to perform a survey to the rigors of a Class 3 survey area on metal structures such as interior and exterior siding, side support beams, sheet metal roof, and overhead roof struts in the structure. The classification downgrade of the exterior and interior surfaces of the building structure are reasonable and appropriate given the characterization of the facility and the FSS data collected from the Class 2 and Class 3 survey areas surrounding the structure.The above changes to classification for FSS of the WMF standing structure and WMF Storag.e Pad will be reflected in the biennial update to the LTP.PG&E makes no new or revised regulatory commitments (as defined by NEI 99-04) in this letter.
