Waste Control Specialists LLC

Waste Control Specialists LLC, doing business as W C S, operates as a federal prime contractor and subcontractor providing treatment, storage, and disposal services for radioactive, hazardous, and mixed waste streams to the Department of Energy, Army Corps of Engineers, Environmental Protection Agency, and Department of Defense. The Dallas, Texas-based for-profit limited liability company competes full-and-open across its prime footprint—no set-aside designations appear in the award record—and operates a licensed disposal facility in Andrews County, Texas that serves as the primary performance location for most federal work. The vendor's capability portfolio centers on transuranic waste management, low-level radioactive waste disposal, greater-than-class C waste storage, elemental mercury long-term management, and hazardous waste treatment, with secondary exposure to ammunition demilitarization and facility support services.

Customer concentration is extreme and single-agency dependent. The Department of Energy Office of Environmental Management funds 65 awards carrying $589.3 million in combined potential value—roughly 76% of the vendor's entire $777.7 million prime and sub footprint. Within DOE-EM, work spans transuranic waste removal from Los Alamos National Laboratory, interim storage and monitoring of greater-than-class C waste at the Andrews County facility, elemental mercury management, and low-level radioactive waste disposal supporting the Waste Isolation Pilot Plant operations. The Army Corps of Engineers ranks second by potential value: the Kansas City District engineering office anchors six awards worth $168.1 million under a $49.9 million multiple-award Blanket Purchase Agreement for radioactive waste disposal (USACE Nationwide Radiological Waste Disposal 2024-2029), executing calls for soil and waste disposal at former DuPont Chambers Works and Welsbach Superfund sites in the Northeast. The EPA Region 6 and EPA Region 3 round out the top-five customer set with five and three awards respectively. Recent representative prime work includes a $15 million DOE-EM delivery order (issued September 2024, ultimate completion December 2026) for interim storage and monitoring of transuranic and greater-than-class C waste; a $12.1 million DOE-EM delivery order (issued September 2023, completion September 2026) for transuranic waste removal and staging from Los Alamos; a $3.2 million Army Corps of Engineers BPA call (issued January 2026) for radioactive waste disposal from the DuPont Chambers Works FUSRAP site in San Antonio; and a $1.4 million EPA Region 6 definitive contract (issued September 2022) for long-term storage of greater-than-class C waste at the Andrews County facility.

On parent vehicles, the vendor holds a $49.9 million multiple-award BPA with the Army Corps of Engineers Kansas City District effective through April 2029, under which recent task orders flow primarily for Superfund remediation site disposal. DOE-EM awarded a single-award indefinite delivery contract (November 2024, ceiling $17.98 million, completion November 2029) for elemental mercury long-term management and storage, and a Basic Ordering Agreement (December 2025, no dollar ceiling, completion December 2030) establishing a framework for firm fixed-price and fixed unit-rate task orders for treatment and disposal of low-level and mixed low-level radioactive waste across DOE sites nationwide. The vendor also holds a $14.4 million DOE TENORM Disposal IDIQ (15 task orders) and participates in older indefinite delivery vehicles such as DACW4199D9007 (16 task orders, Army Corps). Combined potential value exposed to recompete in the next twenty-four months stands at $17.6 million across four awards.

Award activity accelerated sharply in 2024 (29 awards) after relatively sparse 2022-2023 (two and ten awards respectively), then moderated to ten awards in 2025 and six in 2026 year-to-date. SCI-reported invoiced revenue on federal service contracts above the $150,000 reporting threshold totaled $25.5 million across FY2022–FY2025, with $15 million in FY2024 (23.2 FTEs) and $9.2 million in FY2025 (13.9 FTEs); FY2023 showed zero reported activity. Government-paid rates on SCI prime contracts derived from invoiced dollars cluster around $331.75 per hour at the median, with a 10th percentile of $195.50 per hour. Across SCI-reportable prime contracts, the vendor self-performed 100% of labor hours with zero subcontractor engagement.

In its subcontractor posture, WCS subcontracts to large prime contractors managing federal nuclear facilities and environmental remediation programs. Named primes include Triad National Security LLC (Los Alamos National Laboratory management and operations, with WCS performing industrial cleaning, fixtures, and equipment disposal work across multiple 2025-2026 sub awards); Consolidated Nuclear Security LLC (Y-12 National Security Complex and Pantex Plant operations, waste treatment and disposal); UT-Battelle LLC (Oak Ridge National Laboratory spent primary resin liner disposal); General Dynamics Ordnance and Tactical Systems Inc. (20mm depleted uranium demilitarization and disposal); Pantexas Deterrence LLC (Pantex Plant waste treatment and disposal); Fluor Marine Propulsion LLC (Naval Nuclear Laboratory waste broker services); and multiple DOE facility management contractors performing work under the WIPP National Transuranic Waste Program. Sub work follows the same specialized hazardous and radioactive waste streams as the prime portfolio, routed through federal facility management and operations contracts rather than standalone environmental remediation procurements. The 66-34 split favoring prime work (85 prime, 44 sub awards) reflects WCS's core positioning as a specialized waste disposal provider to federal agencies, with subcontract engagement concentrated in facility support roles under large DOE and Department of Defense prime contractors.
