About this opportunity
The Department of the Interior's Interior Business Center has awarded contract GS10F230BA to HSG, LLC on a sole-source basis for environmental technical support services at the Formosa Mine Superfund Site near Riddle, Oregon, under the GSA Multiple Award Schedule program.
The justification cites FAR 8.405-6(a)(1)(i)(B), only one responsible source, on the ground that the required services are unique and highly specialized. HSG possesses advanced expertise in mine-impacted watershed analysis and environmental data interpretation, with access to a hydrologic scientist holding a Ph.D. in hydrology and nationally recognized expertise in mountain hydrology and mining-influenced water systems, including peer-reviewed publications on acid mine drainage characterization and surface water-groundwater interactions. Market research confirmed that other FSS contractors lack the integrated environmental science capability and specialized expertise required. The work supports the Comprehensive Environmental Response, Compensation, and Liability Act process and involves technical discussions, meetings, research, analysis, and evaluation of remediation solutions for a site currently discharging acid rock drainage and heavy metals into Middle Creek and South Fork Middle Creek drainages. The contract includes a base year beginning approximately April 15, 2026, with two additional option years. HSG, LLC is located at 2831 Saint Rose Parkway, Suite 213, Henderson, NV 89052-4840; Point of Contact: Blake Tubbs, 321-326-0055.
