US Ecology Washington Inc.

US Ecology Washington Inc., a subsidiary of publicly traded Republic Services Inc., provides low-level radioactive waste (LLRW) disposal, acceptance, transportation, and ancillary services to the Department of the Navy as a prime contractor operating exclusively on full-and-open (non-set-aside) awards. The company operates a specialized disposal facility in Richland, Washington, located within a Department of Energy complex and serves as the sole source for naval nuclear waste management across the Navy's shipyard network.

US Ecology Washington's federal footprint consists almost entirely of delivery orders and one definitive contract issued by Naval Sea Systems Command (NAVSEA), with 99% of 280 total awards and $258.8 million of combined potential value concentrated at NAVSEA. The remaining activity splits across the Navy's Pacific Fleet Forces, the Department of Energy's Office of Environmental Management, Naval Supply Systems Command, and the National Oceanic and Atmospheric Administration. Activity has remained modest and steady — six awards in 2022, twelve in 2023, five in 2024, eight in 2025, and five in 2026 — with combined dollars obligated at roughly 12% of potential value, reflecting the firm-fixed-price, task-order-driven execution model. Only five awards carrying $833 thousand in combined potential value reach completion within the next twenty-four months, indicating a low near-term recompete exposure.

The company's capability portfolio is tightly scoped around Class A, B, and C LLRW management. Representative work includes a single-award indefinite-delivery/indefinite-quantity contract valued at $155.4 million awarded September 1, 2023, and extending through August 31, 2028, designated sole-source by NAVSEA and covering acceptance, transportation, and disposal of radioactive waste generated at Puget Sound Naval Shipyard and Pearl Harbor Naval Shipyard, along with container disposal services, dose rate measurements, facility maintenance, and nuclear program data and records. Recent delivery orders under that parent vehicle include $290.3 million for LLRW disposal by volume at Richland (September 2025), $188.4 million for Puget Sound Naval Shipyard site availability charges (January 2026), and $177.9 million for Pearl Harbor Naval Shipyard site availability charges (March 2026). A secondary definitive contract with the Department of Energy's Office of Environmental Management, valued at $97.8 thousand and awarded June 21, 2023, covers a five-year sole-source purchase of LLRW disposal data from the contractor's facility.

NAICSNAICS coding reflects the specialized waste-handling scope: 206 awards carry Hazardous Waste Treatment and Disposal (494510), and 73 carry Hazardous Waste Collection (494513). PSC coding shows 192 awards under Housekeeping–Waste Treatment/Storage (D341) and 77 under Environmental Systems Protection–Environmental Remediation (R425). The top four parent indefinite-delivery vehicles under which NAVSEA issues task orders are the 2008-vintage contract N0040608D8010 (120 task orders, $10.4 million), the 2013-vintage contract N0040613D3014 (71 task orders, $8.7 million), the 2018-vintage contract N4523A18D4000 (51 task orders, $7.8 million), and the 2023-vintage contract N4523A23D4000 (20 task orders, $3.8 million). These vehicles reflect generational progression in contract vehicles; the newest carries the most recent, highest-value award. The company holds no seat on government-wide acquisition contracts, regional vehicle fleets, or multi-agency IDIQs and operates exclusively within NAVSEA's contract administration. US Ecology Washington operates as a 100% prime footprint — no subcontract work appears in the source — and competes in full-and-open markets without set-aside designation, positioning itself as a sole-source specialist provider to naval nuclear operations rather than a competitive bidder across broader federal markets.
