About this agency
Environmental Protection Agency Region 4, a sub-agency of the Environmental Protection Agency under the cabinet-level Department of Interior, administers federal contracts and grants for environmental remediation, compliance, and facility management across Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee. Region 4 transacts both sides of the federal ledger—contracts for direct environmental services and grants to state environmental agencies.
On the contract side, EPA Region 4 has awarded 2,783 contracts totaling $1.75 billion in combined potential value since 1999, with $1.65 billion obligated to date. Recent activity shows 82 awards in 2022, 83 in 2023, 60 in 2024, 75 in 2025, and 50 year-to-date in 2026. The competitive landscape is moderately concentrated: the top five primes by award count—Environmental Restoration LLC (46 awards, $32.9 million), Tetra Tech, Inc. (40 awards, $18.8 million), C M C, Inc. (23 awards, $150 million), Kemron Environmental Services, Inc. (16 awards, $67.5 million), and Entech Instruments, Inc. (14 awards, $590 thousand)—together hold 37 percent of recent awards by count. By potential value, the top five are led by C M C, Inc. ($150 million), Kemron Environmental Services, Inc. ($67.5 million), and Environmental Restoration LLC ($32.9 million), accounting for 17 percent of combined value. The remaining 660 contractors form a long tail. Set-asides are minimal: 78 percent of awards carry no set-aside designation, 17 percent are small-business awards, and 3 percent combined are competitive or sole-source 8(a), SDVOSB, HUBZone, or WOSB awards.
On the grant side, EPA Region 4 has obligated $13.88 billion in federal dollars across 2,200 grants to 611 distinct recipients since 1995, with combined total dollars (federal and non-federal share) reaching $15.53 billion. Grant awards were 304 in 2022, 384 in 2023, 323 in 2024, 307 in 2025, and 42 year-to-date in 2026. Recipient concentration is high: the top five recipients by award count—North Carolina Department Of Environmental Quality (88 awards, $1.85 billion federal), Department Of Environment & Conservation Tennessee (78 awards, $797.2 million federal), Florida Department Of Environmental Protection (71 awards, $3.54 billion federal), South Carolina Department Of Environmental Services (67 awards, $501.8 million federal), and Al Department Environmental Management (56 awards, $635.7 million federal)—collectively hold 26 percent of recent awards by count but 55 percent by federal dollars obligated when measured against the top five by dollar value. Florida leads by federal share at $3.54 billion, followed by North Carolina ($1.85 billion) and Georgia Environmental Finance Authority ($814.4 million). Assistance types are evenly split across Formula Grants (34 percent), Project Grants (33 percent), and Cooperative Agreements (33 percent). All five top recipients are state environmental agencies, reflecting EPA Region 4's grant-making orientation toward direct pass-through to state environmental programs.
