Statement of Work Contaminate Removal Action, Abandoned Firing Range

Tule Lake National Wildlife Refuge, CA April 27, 2018

1. General

The purpose of this contract is to remove lead shot from the soil of an abandoned small arms range at Tule Lake NWR per the attached Work Plan. The Work Plan was prepared by Ahtna Environmental Inc. (Ahtna) to guide field staff in the future cleanup of lead associated with the former small arms firing range at the Tule Lake National Wildlife Refuge (NWR).

The location and layout of the Tule Lake NWR firing range is shown on Figures 1 and 2. The purpose of the attached Work Plan is to document site specific ecological risk-based threshold concentration (RBTC) for lead, proposed remedial action areas, the methods that will be utilized for the removal, dust management protocols, disposal requirements, and backfill and grading requirements.

Camp Tule Lake is a culturally significant property on the Tule Lake National Wildlife Refuge that served as a civilian conservation center and segregation facility. The camp was established by the U.S. government in 1935 to accommodate vocational trainees as part of the expansion of available land for the Klamath Reclamation Project. During World War II the camp was used for sheltering Japanese American strikebreakers, imprisoning Japanese American dissidents, and housing Italian and German prisoners of war. After the war, on 25 April 1946, the camp was transferred from the Army back to the U.S. Fish and Wildlife Service (Service). In 2008, Camp Tule Lake was included as part of the larger Tule Lake Unit when it was designated as the WWII Valor in the Pacific National Monument. Camp Tule Lake is currently co-managed by the Service and the National Park Service (NPS). The purpose of the Tule Lake Unit is to preserve, study, and interpret the history and setting of the incarceration and later segregation of Japanese Americans at Tule Lake during World War II.
