Calumet Montana Refining, LLC

Calumet Montana Refining, LLC, doing business as M R C, operates as a prime contractor supplying aviation turbine fuel and naval distillate to the Defense Logistics Agency Energy under single-award indefinite-delivery contracts, competing on an unrestricted full-and-open basis with no set-aside designations applied to its delivery orders. The company is a for-profit limited liability partnership and specialty petroleum refiner headquartered in Great Falls, Montana, classified under NAICS 324110 (Petroleum Refineries) with PSC 9130 (Liquid Propellants and Fuels, Petroleum Base) as its dominant work category.

Calumet Montana Refining serves a single customer agency: the Defense Logistics Agency Energy accounts for 429 of 438 total awards (99% coverage) valued at $235.5 million combined potential value. Three additional awards worth $382 thousand flow to the Department of the Interior Bureau of Indian Affairs Rocky Mountain Region. The customer concentration is extreme—DLA Energy dominates 84 percent of the vendor's combined potential value, with the remaining value negligible.

The company holds five active single-award indefinite-delivery IDIQ contracts with DLA Energy. The most recent IDIQ, awarded September 26, 2025, carries a $3.3 million ceiling and runs through September 30, 2026, authorizing procurement of aviation turbine fuels (JP-5, Jet A, JA-1) and naval distillate F76 for the Rocky Mountain, West Coast, and Offshore regions. An earlier IDIQ awarded September 26, 2024, carries a $4.8 million ceiling through September 30, 2025. A $3.58 billion IDIQ awarded September 8, 2023, authorized over 916 million gallons of fuel annually through September 2024 and incorporated a partial 21.87 percent small business set-aside for fuel quantity, though Calumet Montana Refining's individual delivery orders do not carry set-aside designations. Earlier IDIQs valued at $3.84 billion (August 2022) and $1.9 billion (October 2021) establish a multi-year pattern of substantial DLA Energy fuel procurement vehicles. The five parent IDIQs carry 225 task orders combined, with average delivery order values ranging from $23,000 to over $347,000 and completion timelines of days to weeks, reflecting time-sensitive military fuel logistics.

Recent activity shows 42 awards in 2025 and 37 in 2024, following 43 in 2023 and 23 in 2022. The portfolio is heavily skewed toward DLA Energy delivery orders: individual awards consistently fund fixed-price contracts with economic price adjustment for specific turbine fuel quantities delivered to Great Falls, Montana, for distribution via tanker, barge, truck, railcar, and pipeline to military installations across Rocky Mountain, West Coast, and Offshore regions. Place of performance is Great Falls, Montana across all work in the source.

Calumet Montana Refining operates no subcontract footprint and does not engage subs on its federal awards; all 438 awards are prime contracts. The vendor competes exclusively in the unrestricted marketplace—no small business set-asides, 8(a) certifications, HUBZone designations, SDVOSB status, or women-owned classifications appear in the source. The company's characteristic posture is full-and-open competition as a large petroleum refinery supplying bulk commodity fuel to a single dominant customer under recurring multi-year IDIQs with short-cycle delivery orders.
