Environmental Assessment Services, LLC

Environmental Assessment Services, LLC, an Alaska Native Corporation-owned small disadvantaged business based in Richland, Washington, delivers environmental assessment, NEPA compliance, cultural resource surveys, and natural resource management services to Department of Defense installations and civilian federal agencies as a prime contractor operating entirely on its own (100% prime awards). The firm operates as a subsidiary of Koman Holdings, LLC (itself an Alaska Native Corporation) and carries SBA 8(a) certification; it competes predominantly under 8(a) sole-source set-asides for its core Department of Defense work, though many of its delivery orders under indefinite delivery vehicles carry no set-aside designation.

Environmental Assessment Services' capability portfolio is concentrated in environmental compliance and assessment work across military installations. The firm specializes in environmental impact analyses, National Environmental Policy Act documentation, baseline environmental assessments, cultural and archaeological surveys, endangered species evaluations, wetlands assessments, ecological studies, and natural resource management support. Representative prime work includes a $24.9 million single-award 8(a) sole-source IDC awarded by USACE Fort Worth District (ENDIST Fort Worth) in March 2025 for environmental assessment and compliance services across multiple geographic regions with completion through March 2028; a $9.9 million single-award 8(a) sole-source IDC awarded by USACE Southwestern Division in September 2024 for environmental consulting services through September 2029; a $8.4 million USACE Environmental Laboratory IDC awarded in May 2025 for aquatic plant management and environmental assessment services through May 2030; a $7.761 million 8(a) sole-source definitive contract from USACE Fort Worth for Prado Dam off-site habitat restoration in California (April 2025, completion April 2030); and a $7.7 million delivery order under the Biological and Ecological Studies MATOC for Willamette Valley rotary screw trap monitoring of anadromous fish populations (August 2021, completion September 2025). Recent work also includes a $3.44 million delivery order for cultural resources management at Fort Bliss, Texas (September 2025); a $6.454 million 8(a) sole-source contract with the Department of the Army for quality assurance and fish sampling on the Juvenile Fish Transportation Program (February 2025, completion February 2030); and a $470,422 total-small-business purchase order from USDA Forest Service Region 6 for cultural resource documentation surveys on Deschutes National Forest in Oregon (May 2026, completion September 2027).

Customer concentration is heavy with Department of Defense engineering and installation support offices. The top five funding agencies account for 60% of recent awards by count and 78% by potential value. The Department of the Army Corps of Engineers (all districts) represents the dominant customer across both metrics: USACE as a whole holds 14 awards valued at $76.9 million combined; USACE Fort Worth District (ENDIST Fort Worth) holds 10 awards for $39.1 million; and USACE Los Angeles District (ENDIST Los Angeles) holds 19 awards for $28.3 million. The Department of the Air Force Materiel Command Installation and Mission Support Center Civil Engineer Center accounts for 9 awards valued at $4.3 million. The Department of Agriculture Forest Service Region 6 (Pacific Northwest) represents the civilian agency foothold with 6 awards and $10.7 million combined potential value. The two rankings track closely — the Corps of Engineers dominates both volume and dollars — with modest secondary presence in Air Force, Army (non-Corps), Marine Corps, and Naval Facilities Engineering Command work.

Environmental Assessment Services holds significant standing IDCs across USACE districts and Army Contracting Command. The firm's parent vehicle portfolio includes the $24.9 million Fort Worth District 8(a) sole-source IDC (17 task orders, $7.8 million combined potential value as of source date); the $9.9 million USACE Los Angeles District 8(a) sole-source IDC (8 task orders, $6.4 million); the $9.9 million ACC Redstone 8(a) sole-source IDC (5 task orders, $1.6 million as of source date); the $8.4 million USACE Environmental Laboratory IDC for aquatic research (8 task orders, $6.4 million); the $4.5 million Naval Facilities Engineering Command Natural Resources Forestry Base Contract, single-award 8(a) sole source, awarded September 2025; and a $1 million multiple-award Blanket Purchase Agreement with USACE for ecological services in the Mississippi River Basin region, awarded May 2025. Activity has been consistently strong — 12 awards in 2022, 13 in 2023, 14 in 2024, and 20 in 2025 — with 23 awards (combined potential value $21.9 million) reaching ultimate completion within the next twenty-four months, presenting recompete exposure across USACE and Air Force platforms.

The contractor's work is distributed across multiple NAICS categories reflecting its breadth: Environmental Consulting Services (45 awards), Remediation Services (21 awards), Support Activities for Forestry (15 awards), Other Scientific and Technical Consulting Services (7 awards), and minor presence in other technical categories. Service Contract Inventory data is limited to a single FY2022 record showing $2.3 million in SCI-reportable invoiced revenue across 8.0 FTEs on prime work, with subcontractors performing 21% of hours on average — indicating the firm builds most delivery teams internally. Median government-paid rates on SCI-reportable contracts ran around $107.21 per hour. The corporate structure includes two named joint-venture subsidiaries, EAS E&E JV, LLC and EAS WSP JV, LLC, both carrying the same Alaska Native Corporation and small disadvantaged business designations, though the source does not detail their specific roles or active award footprints relative to the parent.
