Site Location:
Hoopa Valley Reservation, CA 95546

In 2018, the Hoopa Valley Fisheries Program uncovered an asbestos dump in the course of a fisheries restoration project. In April 2019, the Tribe submitted a technical assistance request to the Bureau of Indian Affairs (BIA) to conduct a Phase I Environmental Site Assessment (ESA) of the parcel. BIA conducted the review in conformance with ASTM Practice E 1527-13 and published the Phase I ESA in May 2019. The recommendation of the report was for the Tribe to conduct a Phase II ESA to determine the nature and extent of asbestos contamination. At the request of the Tribe, BIA provided limited funding to complete the Phase II ESA.


In 2021, the Tribe was able to hire two contractors to conduct asbestos sampling to determine the extent of the contamination on the parcel and produce the Phase II ESA. The Phase II ESA report, published in August 2021, estimated that a volume of 3,100 cubic yards of potentially contaminated soil would need to be excavated prior to any redevelopment or restoration of the land. At the request of the Tribe US EPA mobilized to the site in summer 2022 to conduct a removal action.
