About this opportunity
The U.S. Forest Service is soliciting quotations for remediation services under solicitation 1240LU26Q0020 for the Riley Pass Bluff B Mine Waste Excavation Project on the Custer Gallatin National Forest. The project involves excavating historic uranium mine waste containing elevated arsenic and radium-226 concentrations, consolidating the waste in designated areas, conducting roadway reconditioning on approximately 10 miles of National Forest Service Roads, and implementing revegetation through sterile rye seeding across 67 acres. Quoters must demonstrate recent and relevant experience with similar projects completed within the past five years and provide documentation of past performance on at least five comparable projects. Evaluation will be conducted using comparative methodology based on experience relevancy and confidence assessment, past performance quality and recency, and price fairness and reasonableness. Critical deadlines include February 23, 2026 at 12:00 PM Mountain Time for submission of clarifying questions, and March 3, 2026 at 4:00 PM Mountain Time for quotation submission; award is anticipated 2-3 weeks after quotation submission with Notice to Proceed following 1-2 weeks after the pre-award meeting and receipt of required bonds.
This solicitation is designated as a 100% small business set-aside under NAICS 562910 (Remediation Services) with a 1,000-employee size standard, issued as a Request for Quotation for commercial items under FAR Part 12. The previous contract for similar services was performed under contract number 1240LU25C0002. The estimated contract value ranges between $1,000,000 and $5,000,000, with the project scope encompassing excavation of 310,000 total cubic yards of mine waste (225,000 cubic yards in Area 1 and 85,000 cubic yards in Area 2), along with associated borrow and placement operations. Work must be completed with all non-seeding activities finished by July 1, 2026, a firm contractual deadline, while seeding is required either prior to June 15, 2026 or between September 15-October 15, 2026. The place of performance is Harding County, South Dakota, specifically at the Riley Pass Bluff B location on the Custer Gallatin National Forest.
