Pre-placed Remedial Action Contract Phase B

The U.S. Army Corps of Engineers Engineering District Kansas City awarded this Master IDIQ on September 2, 2020, to support hazardous, toxic, and radioactive waste remediation projects for the USACE Northwestern Division and EPA Region 2, with a shared ceiling of $185 million over a five-year ordering period ending March 1, 2026. Ordering is now closed; the last date to order passed in March 2026.

The vehicle is fully unrestricted; all 17 awarded task orders carry no set-aside designation. Work covers remediation activities including hazardous waste site cleanups, groundwater treatment, dredging, facility decommissioning, and in situ remediation across nine Midwestern states and EPA Region 2. Pricing is predominantly cost-plus-fixed-fee, with task-order durations ranging from roughly one to five years. The most recent orders awarded in mid-2023 include the 18 Mile Creek remedial action ($57.2 million ceiling), the Vestal thermal remedial action ($24.1 million), and the Former Kil-Tone OU2 Phase 1 remedial action ($11.2 million).

Sevenson Environmental Services, Inc. dominates the vehicle, holding six task orders with combined potential value of $122.7 million—roughly 63% of the combined task-order portfolio. Cape Remediation, LLC holds three orders ($47.8 million), and Aptim Federal Services, LLC holds two orders ($24.1 million); these three firms account for 100% of combined potential value. Six smaller contractors have been awarded one order each but collectively represent less than $10 thousand.

Customer concentration is sharp: EPA Region 2 placed seven orders representing $180.9 million of the $194.6 million combined portfolio—roughly 93% of activity by value. The USACE Engineering District Kansas City placed nine orders but only $15 thousand combined potential value, primarily minimum-guarantee orders issued at vehicle inception. One additional USACE district (Philadelphia) placed a single $13.6 million order.

Combined task-order dollars obligated total $193.6 million against $194.6 million potential value—99% obligation. Ordering momentum declined sharply; nine orders were placed in 2020, five in 2022, and three in 2023, with no new awards since August 2023.

This Pre-placed Remedial Action Contract (PRAC) will support work assigned to the U.S. Army Corps of Engineers (USACE) Northwestern Division and the Environmental Protection Agency (EPA) Region 2, for hazardous, toxic and radioactive waste (HTRW) remediation projects for both civilian and military agencies of the Federal Government.
