Waste Control Specialists LLC

Waste Control Specialists LLC, doing business as W C S, is a for-profit limited liability company based in Dallas, Texas that provides treatment, storage, and disposal services for radioactive, hazardous, and mixed waste to federal agencies, competing predominantly as a prime contractor (67% of recent awards) on full-and-open (non-set-aside) contracts. The vendor operates a licensed disposal facility in Andrews County, Texas, which serves as the primary operational hub for federal waste management work across a portfolio anchored by the Department of Energy's Office of Environmental Management.

Customer concentration is extreme and mission-critical. DOE-EM accounts for 64 of 126 total awards (51% of the portfolio by count) and $589.3 million of $777.4 million combined potential value (76% of dollars). This concentration reflects the vendor's specialized role in managing transuranic waste, low-level radioactive waste, greater-than-class C waste, and elemental mercury streams across the federal government's environmental remediation and cleanup portfolio. The Army Corps of Engineers Engineering District Kansas City ranks second but a distant second, with 6 awards carrying $168.1 million in potential value, driven largely by a $49.9 million multiple-award BPA for radioactive waste disposal services (effective May 1, 2024, through April 30, 2029) and a $40 million multiple-award BPA awarded September 2021 (ultimate completion September 2026). The Environmental Protection Agency Region 6 and Region 3 contribute smaller volumes. The portfolio covers 15 distinct agencies, but the top three customers (DOE-EM, Army Corps Kansas City, and Army Corps generally) account for substantially all dollars and most volume.

Waste Control Specialists operates under a multi-vehicle strategy centered on indefinite delivery contracts and blanket purchase agreements rather than single-award vehicles. The parent vehicles with the deepest task-order activity are: an Indefinite Delivery Contract (DACW4199D9007) with 16 task orders; a DOE TENORM Disposal IDIQ with 15 task orders and $14.4 million combined potential value; a Basic Ordering Agreement (89303321GEM000020) with 5 task orders and $57.6 million combined potential value; and several Army Corps IDCs. Representative prime work includes a $15 million delivery order from DOE-EM (Office of Environmental Management) awarded September 12, 2024, for interim storage, monitoring, and management of 74 shipping containers of transuranic and greater-than-class C waste through December 2, 2026; a $12.1 million firm fixed-price delivery order from DOE-EM awarded September 28, 2023, for removal of transuranic waste from storage and staging at the contractor's Dallas facility through September 30, 2026; a $3.22 million BPA call from the Army Corps of Engineers (USACE Nationwide Radiological Waste Disposal 2024-2029) awarded January 21, 2026, for radioactive waste disposal at the Former DuPont Chambers Works FUSRAP site through January 20, 2029; and an $18 million single-award Indefinite Delivery Contract from DOE-EM awarded November 21, 2024, for elemental mercury long-term management and storage through November 30, 2029. A Basic Ordering Agreement with DOE-EM for treatment and disposal of low-level and mixed low-level radioactive waste was executed December 3, 2025, with no specified ceiling and orders authorized through December 3, 2030.

Recent activity shows sharp growth trajectory. Awards numbered 2 in 2022, ramped to 10 in 2023, climbed to 29 in 2024, then settled to 10 in 2025 and 3 year-to-date through March 2026. Combined potential value across all 126 awards stands at $777.4 million with $122 million obligated (16% of the ceiling). Four awards with combined potential value $29.6 million face ultimate completion dates within the next twenty-four months, creating recompete exposure for the vendor and recompete opportunity for competitors.

In its subcontractor role (33% of recent awards), Waste Control Specialists delivers industrial cleaning, fixtures and equipment removal, waste treatment, disposal, and transportation services to prime contractors managing DOE national laboratories and weapons production facilities. Named prime relationships include Triad National Security, LLC (Los Alamos National Laboratory M&O work); Pantexas Deterrence, LLC and Consolidated Nuclear Security, LLC (Pantex Plant and Y-12 National Security Complex management and operations); General Dynamics Ordnance and Tactical Systems, Inc. (demilitarization and disposal of 20mm depleted uranium ammunition); Fluor Marine Propulsion, LLC (Naval Nuclear Laboratory waste broker services); and prime contractors operating the Waste Isolation Pilot Plant (WIPP) for transuranic waste handling and low-level waste treatment and disposal. The subcontract footprint is volumetric — the source lists 42 sub-award line items spanning 2023 to March 2026 — and reflects WCS's position as a critical supplier to the DOE's nuclear weapons complex and waste management infrastructure.

On SCI-reportable federal service contracts (a partial view excluding goods, micro-purchases, and non-federal revenue), WCS invoiced $16.3 million across FY2022–FY2024, with $1.3 million and 4.5 FTEs in FY2022, zero invoicing in FY2023, and a sharp jump to $15 million and 23.2 FTEs in FY2024. Government-paid rates on these contracts ranged from around $195/hr at the 10th percentile to $331.75/hr at the median and 90th percentile, reflecting a portfolio of facility operations, technical support, and waste management labor. Across SCI-reportable prime contracts, WCS performed all work itself with 0% sub-hour share, indicating vertical integration of delivery. The SCI dataset captures only a slice of WCS's federal revenue — facility operations and hazardous waste disposal contracts often fall outside the $150,000 threshold or are structured as supply contracts rather than service contracts — so these figures understate the vendor's actual federal footprint substantially.
