About this agency
The Environmental Protection Agency Office for Air and Radiation - Funding Office, a sub-agency within the civilian EPA, administers contract and grant funding for air quality and radiation-related environmental research, monitoring, and compliance programs nationwide. The office has awarded 6,508 federal contracts totaling $4.27 billion in combined potential value since 1979, with $2.75 billion obligated to date. Contract award volume has remained steady at 197 to 235 awards annually from 2022 through 2024, declining to 134 awards in 2025 and 111 year-to-date in 2026.
Eastern Research Group Inc. leads the contractor base by recent award count with 98 awards valued at $160.9 million combined potential value over the last five years, followed by ICF Incorporated, L.L.C. with 78 awards ($148.9 million) and Research Triangle Institute with 61 awards ($137.2 million). The top five contractors by award count account for 34 percent of recent awards; by potential value, the top five hold 14 percent, indicating a fragmented competitive landscape with a long tail of 1,197 distinct prime contractors. Eighty-nine percent of awards carry no set-aside designation; small-business awards comprise 7 percent of the portfolio, while 8(a), HUBZone, SDVOSB, and WOSB designations together represent less than 2 percent of awards.
Grant activity is minimal and episodic. The office has issued 86 federal grants totaling $478.3 million in federal dollars obligated since 1998, with one award in 2026, four in 2025, and a spike of 31 awards in 2024; 2022 and 2023 each saw only two awards. Project Grants dominate at 90 percent of awards, with Cooperative Agreements at 8 percent and Formula Grants at 2 percent. Grant funding is highly concentrated, with the top five recipients by federal dollars accounting for 66 percent of obligated federal share. Oregon Department of Environmental Quality leads by federal share with a single award of $197.2 million, followed by NEZ Perce Tribe and The Southeast Conference, each with awards exceeding $38 million. The remaining 41 recipients are universities, tribal entities, nonprofits, and state agencies, each holding modest individual awards.
Recent contract opportunities reflect routine procurement: a simplified acquisition for repair of Canberra gamma radiation detectors for the National Analytical Radiation Environmental Laboratory (solicitation 68HE0M27Q0001, due November 12, 2026) and a simplified acquisition for Signature Device Carts materials (68HE0M26Q0023, closed October 6, 2026).
