Tanaq-Mes 8(A) JV, LLC

Tanaq-Mes 8(A) JV, LLC, an Alaskan Native Corporation-owned joint venture certified as a small disadvantaged business under the 8(a) program, delivers environmental compliance, remediation, and facility engineering services to the Department of Defense as a prime contractor across 30 recent federal awards. The joint venture is organized as a division of ST George Tanaq Corp, an Alaskan Native Corporation and minority-owned enterprise headquartered in Anchorage, Alaska. Tanaq-Mes competes predominantly in 8(a) set-asides (sole source and competitive designations) on its three held indefinite delivery contracts, though recent delivery orders show mixed posture—some issued under 8(a) designation and others under unrestricted competition.

Tanaq-Mes' capability portfolio centers on environmental compliance and remediation engineering services at military installations. Concrete work includes hazardous waste management planning and contingency planning, EPCRA (Emergency Planning and Community Right-to-Know Act) reporting, pollution prevention planning, PFAS (per- and polyfluoroalkyl substances) remedial investigations, waste stream determination, and treatment facility installation and removal. Representative awards include a $2.8 million 8(a) sole source delivery order from the Air Force Civil Engineer Center for Phase I PFAS remedial investigation at Montgomery Air National Guard Base, Alabama (issued September 2023 under an Army Corps of Engineers IDC); an $860,165 8(a) sole source delivery order from the Army Reserve Command for environmental compliance technical support to the 81st Readiness Division in Columbia, South Carolina (September 2024); and a $1.82 million firm-fixed-price delivery order from ENDIST Mobile for FY25 81st Tanks Technical Support in Columbia, South Carolina (September 2025, no set-aside).

Customer concentration sits overwhelmingly with the Department of Defense. The top five customer organizations account for 90% of awards by count. The Air Force Civil Engineer Center dominates potential value with three awards totaling $102.8 million combined, anchored by a $100 million multiple-award indefinite delivery contract awarded March 3, 2025, for architect-engineering environmental services worldwide through March 5, 2035 (partial small business set-aside). The Army Corps of Engineers Engineering District Mobile has issued four awards totaling $13 million, including a $9.9 million single-award 8(a) sole source IDC (September 2023 through September 2027) for facility maintenance and environmental program support. Naval Facilities Engineering Command has awarded 12 delivery orders totaling $10.7 million under a $10 million single-award 8(a) sole source IDC (April 2024 through May 2029) for maintenance, installation, remediation, and facility environmental services. The Navy's United States Fleet Forces Command (Atlantic) and Navy Installations Command round out active customers.

Tanaq-Mes places task orders under three parent indefinite delivery contracts. The largest vehicle by task order volume is Indefinite Delivery Contract N6945024D0008 (19 task orders, $1.4 million combined potential value), followed by Indefinite Delivery Contract W9127823D0083 (5 task orders, $6.8 million combined potential value) and Indefinite Delivery Contract FA890325D0010 (1 task order, $3 thousand). The $100 million Air Force Civil Engineer Center contract and $10 million Naval Facilities Engineering Command contract represent the highest-ceiling vehicles in the footprint.

Activity has accelerated sharply. Awards per year grew from four in 2023 to seven in 2024 to eighteen in 2025, with one award to date in 2026. Combined potential value across all thirty awards stands at $129 million, with $6.2 million obligated (5% of potential), reflecting the recent and near-term nature of much of the portfolio. Twelve awards with combined potential value $4.6 million reach ultimate completion within the next twenty-four months, creating recompete exposure. Tanaq-Mes operates solely as a prime contractor—the source contains no subcontract awards. Work is performed at military installations nationwide including Letterkenny Army Depot (Pennsylvania), Naval Station Mid-South (Tennessee), Naval Support Activity Panama City (Florida), and overseas locations, with administrative oversight in Anchorage.
