About the company
Mammoth Disposal Company, doing business as Mammoth Disposal, holds prime federal contracts for portable sanitation and waste management services across Western public lands, with all seventeen recent awards issued as competitive purchase orders carrying no small business set-aside designation. The company is a child entity of Waste Connections US, Inc., a foreign-owned for-profit corporation headquartered in The Woodlands, Texas, and operates from Mammoth Lakes, California, under primary NAICS 4224 (Solid Waste Collection) and PSC Housekeeping–Trash/Garbage Collection.
Mammoth Disposal's footprint is narrowly concentrated among interior agencies managing Western public lands and recreation sites. The Department of the Interior Bureau of Land Management California Region accounts for 98% of combined potential value across recent awards ($107 thousand out of $191 thousand total), driven by a $92.6 thousand base-plus-four-option purchase order from the BLM Bishop Field Office for portable toilet and trash removal services running through August 2028. The United States Marine Corps places four awards worth $31 thousand, the Department of Agriculture Forest Service Pacific Southwest Region holds six awards worth $24 thousand, and the National Park Service Pacific West Region accounts for two awards worth $12 thousand. Work concentrates geographically in California and adjacent regions — Mammoth Lakes, Bishop, Inyo National Forest, and Devils Postpile National Monument — with a single award (June 2025, $11.9 thousand) extending to the BLM's Idaho Region for dumpster container services in Boise through October 2025.
Activity across the past five years shows sporadic placement: two awards annually in 2019 and 2020, four in 2023, two in 2024, and one in 2025. One award (combined potential value $81 thousand) reaches ultimate completion inside the next twenty-four months, creating recompete exposure. Representative work includes the BLM Bishop Field Office's $92.6 thousand purchase order for portable toilet and trash removal services over five periods through August 2028, a National Park Service $3.7 thousand delivery for portable toilet and handwashing station rental and servicing at Devils Postpile National Monument (August 2023), and a Forest Service $817 purchase order for dumpster rental supporting forest management in the Bishop area (July 2023). The vendor operates as a pure prime contractor with no subcontract activity in the source data.
