Noxious Weed-Free Materials Supply

This contract requires the supply of clean fill, gravel, soil, and other specified materials that are certified to be free of noxious weeds for use within Yellowstone National Park. All deliveries must meet strict phytosanitary standards to prevent the introduction and spread of invasive plant species that could harm the park’s native ecosystems. The materials are essential for construction, maintenance, and infrastructure projects in the park and must be sourced, handled, and transported under protocols that ensure weed-free integrity from origin to delivery. The contract is classified as a subcontract under NAICS code 115310, which corresponds to support activities for mining, suggesting the work involves sourcing and logistics of bulk material supply rather than direct extraction. It is managed by the Western Federal Lands Division of the Department of Transportation and is specifically scoped for performance within Yellowstone National Park. The posting date indicates this opportunity was made available in mid-2026, and while no solicitation number is listed, interested parties can access additional details through the provided SAM.gov link. Compliance with weed-free certification is mandatory and non-negotiable for all suppliers.
