Eocene Environmental Group, Inc.

Eocene Environmental Group, Inc., doing business as CN Utility Consulting Inc., provides archaeological and cultural resource services to the Department of Interior Fish and Wildlife Service and the Army Corps of Engineers as a prime contractor on full-and-open and small-business-set-aside delivery orders and indefinite delivery contracts. The company is a for-profit corporate entity based in West Des Moines, Iowa, and operates primarily under NAICS 712120 (Historical Sites) and PSC Special Studies/Analysis—Archeological/Paleontological.

Eocene's recent work centers on National Historic Preservation Act compliance, site identification and evaluation, archaeological testing and evaluation, and National Register of Historic Places eligibility determinations across western states. The customer base is concentrated in the Department of Interior's Fish and Wildlife Service, which accounts for all three awards in the most recent portfolio slice. A $54,922 delivery order from Fish and Wildlife Service Region 1 (September 2026) covered historic property assessment at the Buff Wilson Historic Property in Colville, Washington, with completion targeted for September 2027. A $49,874 order from the same region (also September 2026) addressed cultural resources and historic property identification work in Colville, Washington, running through March 2028. A $171,294 delivery order from Fish and Wildlife Service Region 8 (September 2026) supported cultural resource services at Klamath Marsh, Oregon. Eocene also holds a single-award indefinite delivery contract valued at $499,985.73 with Fish and Wildlife Service Region 1 (awarded December 2024) covering cultural resource investigations across Regions 1 and 8 in Oregon, Washington, Idaho, California, and Nevada, running through December 2027 with two 12-month option years. An earlier $477,595 small-business-set-aside purchase order from the Army Corps of Engineers Engineering District Omaha (September 2023) tasked the company with archaeological testing and evaluation of up to 28 sites across North Dakota and South Dakota to determine National Register eligibility.

At the sub-award level, Eocene received a $1,992,948 five-year grant sub-award from Carbon A List LLC (January 2024) to lead and implement monitoring, reporting, and verification work including baselining, life cycle assessments, greenhouse gas quantification, environmental modeling, and in-field verification. Three awards reach ultimate completion within the next twenty-four months, totaling $276 thousand in combined potential value and triggering recompete exposure. Activity has grown from one award in 2023 to three in 2026, though the portfolio remains small and concentrated in a single parent vehicle—the Fish and Wildlife Service Region 1 indefinite delivery contract—which currently carries three task orders.
