Tri-State Government Services Inc.

Tri-State Government Services Inc., a women-owned small business (WOSB) and economically disadvantaged woman-owned small business (EDWOSB) headquartered in Chattanooga, Tennessee, provides hazardous waste removal, environmental remediation, and disposal services to the Defense Logistics Agency as a prime contractor operating exclusively under total small business set-asides. The company holds a dominant, single-customer relationship with DLA Disposition Services, which accounts for 12,313 of its 12,618 recent prime awards and $304.5 million of $379.3 million in combined potential value — representing 97% of award count and 80% of dollar value.

Tri-State's capability footprint centers on hazardous waste management and environmental remediation for Department of Defense facilities across the Southeastern United States. Core services include disposal of flammable liquids, solids, and sludges; handling of regulated substances such as per- and polyfluoroalkyl substances (PFAS), polychlorinated biphenyls (PCBs), cyanide compounds, and reactive lithium metals; waste characterization and laboratory testing; container management and rental; industrial cleaning; blast media removal; soil excavation; and procurement of specialized materials and supplies. The company executes work at multiple major installations, including Anniston Army Depot (Alabama), Robins Air Force Base (Georgia), Fort Stewart (Georgia), Fort Eisenhower (Georgia), Maxwell Air Force Base (Alabama), and Patrick Space Force Base (Florida). Recent representative work includes a $115,406 annual rental delivery order for a 25-cubic-yard roll-off bin at Warner Robins Air Force Base (January 2026), a $126,734.24 delivery order for corrosive organic acids disposal at Anniston Army Depot (March 2026), and a $125,700 annual rental delivery order for a 20-cubic-yard roll-off container at Anniston Army Depot (December 2025).

Tri-State holds two active indefinite delivery contracts with DLA Disposition Services. The primary vehicle, awarded March 10, 2023, carries a ceiling of $42.79 million with an ultimate completion date of March 9, 2028, and is designated a total small business set-aside. Since award, DLA Disposition Services has issued over 180 delivery orders under this vehicle, ranging from under $100 to over $115,000, with completion periods typically eight to twelve months. A second, newer IDV was awarded December 1, 2025, with a ceiling of $26.08 million, an ultimate completion date of November 15, 2031, and firm fixed-price pricing under a 30-month base period with one optional 30-month extension. The second contract originated from a December 2024 sources-sought notice seeking comprehensive hazardous waste removal, transportation, and disposal services for military installations in Alabama and Tennessee. Both vehicles support hazardous waste removal and disposition covering Resource Conservation and Recovery Act (RCRA) hazardous wastes, non-RCRA wastes, universal wastes, compressed gases, and polychlorinated biphenyls.

Activity has been stable to declining — 620 awards in 2022, peaking at 744 in 2023, then declining to 643 in 2025 and 183 awards through mid-2026. This reflects the shift from the high-volume task-order activity under the March 2023 IDV to the newly awarded December 2025 vehicle structure. Tri-State's award footprint is heavily concentrated in a single customer (DLA Disposition Services at 97% of awards) and a single service category (Hazardous Waste Treatment and Disposal at 12,347 of 12,618 awards, NAICS 562211). The top five IDVs collectively account for 6,122 task orders; the top parent vehicle (IDV SP450020D0021) alone carries 1,809 task orders with $15.4 million in combined potential value. Within the next twenty-four months, 349 awards with combined potential value $5.2 million reach ultimate completion, representing moderate recompete exposure. Tri-State competes exclusively under total small business set-asides and holds no recorded subcontract awards in the source data. Dollar obligation sits at $145.9 million across 38% of combined potential value, indicating execution is underway but significant value remains unobligated.
