Crst Sanitary Landfill

Crst Sanitary Landfill, a tribally owned subsidiary of the Cheyenne River Sioux Tribe, provides solid waste collection and disposal services to federal agencies in the Great Plains region as a prime contractor operating without set-aside designation. Based in Eagle Butte, South Dakota, the firm competes full-and-open on definitive contracts and purchase orders; all seven recent federal awards (2022–2026) carry no set-aside restriction despite the vendor's tribal ownership eligibility.

The vendor's customer base consists entirely of Interior and Health and Human Services agencies serving tribal trust lands and tribal communities. The Department of the Interior Bureau of Indian Affairs Great Plains Region accounts for five awards totaling $703 thousand in combined potential value, anchoring Crst's footprint on recurring garbage and waste management contracts for the Cheyenne River Agency. The Bureau of Indian Education placed one award for $507 thousand covering solid waste collection services at the Cheyenne Eagle Butte School with a five-year performance window (April 2025 through April 2030, base plus four one-year option periods). The Department of Health and Human Services Indian Health Service awarded one $249.5 thousand purchase order for solid waste disposal at the Cheyenne River Health Center. The three customer agencies account for 100% of recent awards and combined potential value.

Crst operates exclusively as a prime contractor (100% of recent awards); the firm has no subcontract or sub-grant activity in the source data. The vendor's capability footprint is narrow and location-specific: all seven awards are for waste management services performed in Eagle Butte, South Dakota, classified under NAICS 562111 (Solid Waste Collection) and 562212 (Solid Waste Landfill), with all tasks scored under PSC code S206 (Housekeeping—Trash/Garbage Collection). Recent work includes the $249.5 thousand one-year Indian Health Service purchase order (ultimate completion August 11, 2027), the $507 thousand five-year Bureau of Indian Education purchase order for campus waste collection (ultimate completion April 27, 2030), and the $175 thousand Great Plains Region waste management purchase order (ultimate completion September 1, 2026). Three awards carrying combined potential value of $283 thousand reach ultimate completion within the next twenty-four months and face recompete exposure. The vendor's combined potential value across all awards stands at $1.5 million, with $1.2 million obligated (79% realization).
