The Pyramid Lake Paiute Tribe plans to redevelop the property for residential or commercial use, and was concerned about existing or potential environmental liabilities. EPA places a high priority on providing Brownfields technical assistance and other support to Tribal Nations. Property Information The Rock Building property includes an area of approximately 0.35 acres that has been vacant since the 1960s. The Rock Building was initially constructed around 1902 by the Bureau of Indian Affairs, which occupied the building through the 1960s. The building is currently unoccupied but historically has been used as a school, residence, and adminis- trative offices. The lot surrounding the building is currently used for vehicle parking by the Pyramid Lake Housing Authority. Technical Assistance The United States Environmental Protection Agency (EPA) provides technical assistance to research historical property uses, conduct environmental sampling and identify cleanup options and costs. The focus of the EPA-funded environmental assessment was to investi- gate potential contamination and characterize conditions at the parcel considered for planned redevelopment or reuse. The Targeted Brownfields Assessment consisted of a combined Phase I/II Environmental Site Assessment (ESA). Findings The combined Phase I/II ESA of the Rock Building included surface and subsurface soil sampling, soil gas sampling, and a hazardous building material survey. The building survey identified the presence of asbestos-containing materials and lead-based paint. Total petro- leum hydrocarbons (diesel and motor oil) were detected at concentrations greater than the state cleanup levels, and polynuclear aromatic hydrocarbons were detected at concentra- tions above the federal residential human health guidelines in soil samples near the former aboveground storage tank used to store heating oil. Recommendations Surface and subsurface soil with contamination exceeding human health guidelines may require removal or capping to prevent future exposure. Any future building improve- ments, remodeling, or demolition would require asbestos and lead-based paint abatement. Future Use The Pyramid Lake Paiute Tribe redevelopment plan for the Rock Building property includes options to renovate the building or demolish it and construct new buildings for residential use or for commercial offices for tribal departments, including the Pyramid Lake Housing Authority.
