Navajo DAM weed treatment

The Department of the Interior's Bureau of Reclamation is procuring invasive plant and algae control services for Navajo Dam in northwestern New Mexico through solicitation 140R4026Q0015. The contractor must treat approximately 100 acres within the Primary Jurisdiction Area and "Boneyard," controlling noxious weeds, undesirable plant species, and aquatic plants while achieving a 90% kill rate and maintaining compliance with environmental regulations including FIFRA, the Endangered Species Act, and the Clean Water Act. Key requirements include possession of a commercial applicator's license for New Mexico, submission of a Safety Plan within 20 days of award, and comprehensive reporting including treatment maps, acreage data, herbicide documentation, and post-treatment assessments. Award will be based on best value considering technical approach, past performance, and price. The proposal deadline is February 20, 2026 at 4:00 PM MDT, with questions due by February 9, 2026; the technical proposal must not exceed 10 pages and include detailed technical approach, quality control plan, personnel qualifications, and licenses or permits.

This opportunity is designated as a total small business set-aside under NAICS 561730 with a $9.5 million size standard, with an incumbent contractor previously performing similar services under contract number 140R4021P0015. The contract is structured as a firm fixed price arrangement with a base period running from April 15, 2026 to December 31, 2026 (8 months and 16 days), followed by four optional one-year periods extending through December 31, 2030. Work will be performed at the Bureau of Reclamation-UC-WCAO Durango Field Division in Durango, Colorado, with on-site operations scheduled Monday through Friday from 7:00 a.m. to 3:30 p.m. and coordinated with the Navajo Dam Maintenance Supervisor. The government anticipates three mobilizations annually (spring, summer, and fall) to address different treatment objectives, though this may be reduced to two efforts if deemed unnecessary during the base year. Past performance documentation should include up to three similar projects completed within the last five years, and invoices must be submitted electronically through the Invoice Processing Platform system.
