D & S Diesel, LLC

D & S Diesel, LLC, a small disadvantaged business based in Pocatello, Idaho, provides diesel mechanic services and on-site vehicle maintenance support to the U.S. Department of Agriculture Forest Service as a prime contractor operating entirely under small-business set-asides. The vendor operates as a limited liability partnership and competes exclusively on total small business set-aside delivery orders and indefinite-delivery contracts (IDCs) issued by the Forest Service's National Interagency Fire Center and regional offices, with no subcontract activity in the source data.

D & S Diesel's capability portfolio centers on wildland fire suppression and emergency-response vehicle maintenance. The vendor provides diesel mechanic services, service-truck support, and on-site maintenance work across the western Forest Service regions, with personnel, equipment, materials, supplies, transportation, and lodging supplied by the contractor. Recent representative work includes a $28,000 delivery order awarded June 29, 2026 (the most recent award) for on-site diesel mechanic services at Monroe, Utah supporting the Intermountain Region's vehicle maintenance needs; a $57,415 firm fixed-price delivery order awarded August 16, 2024 for fire suppression and emergency response vehicle maintenance across Idaho, Utah, and New Mexico; and a $52,500 delivery order awarded August 1, 2025 for service-truck diesel mechanic support to wildland fire and all-hazard incident response efforts.

Customer concentration sits entirely within the Forest Service apparatus. All thirteen awards fund Forest Service operations, split between the National Interagency Fire Center (5 awards, $1.1 million combined potential value), the Forest Service R4-Intermountain Region (5 awards, $178 thousand combined potential value), and the Rocky Mountain Research Station (2 awards, $159 thousand combined potential value). The vendor holds three parent IDCs: a $250,000 multiple-award firm fixed-price IDC awarded August 4, 2026 covering Regions 1, 2, and 4 (East Zone) running through August 4, 2031; a $250,000 multiple-award IDC awarded February 6, 2026 covering the same East Zone regions with a June 8, 2028 completion date; and a $250,000 multiple-award IDC awarded June 8, 2023 for the same geographic coverage through June 8, 2028. Task orders under these IDCs have ranged from $14,000 to $57,415. All work falls under NAICS 811111 (General Automotive Repair) and PSC Natural Resources/Conservation—Forest-Range Fire Suppression/Presuppression.

Activity has been sparse but shows uptick in recent periods: one award in 2022, one in 2023, two in 2024, one in 2025, and three awards in 2026 year-to-date. Combined potential value across all thirteen awards is $1.4 million, with $261 thousand obligated across the portfolio (19% of ceiling). The two most recent IDC awards (February and August 2026) represent the vendor's largest ceiling values and extend through 2028 and 2031 respectively, providing a stable contracting window for small-business set-aside task orders in regional fire and emergency response vehicle maintenance.
