About this agency
The Environmental Protection Agency Region 9, a civilian sub-agency of the EPA, administers federal contracts and grants to support environmental protection, air quality, water resources, and remediation activities across California, Nevada, Arizona, Hawaii, and U.S.-affiliated Pacific territories. Region 9 transacts heavily in both procurement and grant-making, serving as the regulatory and funding hub for environmental compliance and infrastructure support across the region.
Region 9 has awarded 3,171 federal contracts totaling $2.29 billion in combined potential value since 1998, with $2.02 billion obligated to date. Annual contract awards have averaged 98 to 162 per year over the last five years, with 98 awards in 2022, 150 in 2023, 162 in 2024, 96 in 2025, and 100 year-to-date in 2026. The most recent award closed on October 20, 2026. Contract competitive concentration is moderately concentrated among primes by award count; the top five contractors—Toeroek Associates, Inc.

(32 awards, $81.6 million), and EA Engineering, Science, And Technology, Inc., PBC (21 awards, $62.7 million)—account for 44% of recent awards over the last five years. By potential value, concentration is highly fragmented; the top five hold only 18% of combined potential value, with Ch2M Hill, Inc. leading at $118.4 million across 18 awards. Eighty-five percent of all awards carry no set-aside designation, with 11% awarded to small businesses (primarily unrestricted small-business set-asides), 2% as 8(a) sole-source, and 1% as competitive 8(a); remaining designations (SDVOSB, WOSB, HUBZone) are minimal. Region 9 has awarded 622 distinct prime contractors cumulatively.

Annual grant awards were 261 in 2022, 388 in 2023, 394 in 2024, 314 in 2025, and 49 year-to-date in 2026. The most recent grant award closed on October 1, 2026.
