Office of Inspector General

The Environmental Protection Agency Office of Inspector General, a civilian sub-agency within EPA, procures audit, investigation, and oversight support services to fulfill its mission of providing independent review of EPA's programs and operations. The OIG contracts with a broad supplier base to obtain consulting, IT, and administrative services supporting federal audits and investigations.

The OIG awarded 608 federal contracts with combined potential value of $45.2 million since 2005, with 38.7 million dollars obligated to date. Recent activity has declined moderately: 18 awards in 2022, 22 in 2023, 17 in 2024, 15 in 2025, and 14 year-to-date in 2026. The most recent award closed on 2026-09-28.

The competitive landscape is highly fragmented. Over the last five years, the top five awardees by count hold 22 percent of recent awards, led by The Kinetic Group Sales LLC with five awards totaling $176 thousand in potential value, followed by Empowered Systems Holdings LLC, Govsmart Inc., and Colossal Contracting LLC, each with four awards. When ranked by potential value, Booz Allen Hamilton Inc. emerges as the largest single awardee with one contract valued at $2.9 million — substantially larger than other recent primes — but the top five by value cover only 10 percent of combined potential-value across the recent window. The portfolio spans 291 distinct prime contractors across its lifetime, reflecting deliberate use of a broad supply base for OIG work.

Set-asides are minimal. Ninety-one percent of awards carry no set-aside designation, while 7 percent are small-business awards. Fewer than one percent each were designated as 8(a) sole source, competitive 8(a), economically disadvantaged women-owned small business, reserved for small business, service-disabled veteran-owned small business, or women-owned small business. No open federal contract opportunities are recorded in the current solicitation pipeline.
