About Nwestco LLC
Nwestco LLC, operating as Northwest Fuel Systems, provides above-ground and underground fuel storage tank monitoring, maintenance, and repair services to federal agencies as a prime contractor, competing exclusively in full-and-open procurements without set-aside designation. The company is a for-profit limited liability partnership based in Littleton, Colorado, with SAM registration dating to 2015 and primary capability concentration in fuel infrastructure support (NAICS 811198 — All Other Support Services; PSC Housekeeping — Fueling and Other Petroleum).
Northwest Fuel Systems operates almost entirely within a single customer relationship. The Department of the Interior's National Park Service Pacific West Region accounts for seven of twelve awards across the vendor's recent footprint, representing $772 thousand of the $899 thousand combined potential value (86% of total). The remaining five agencies — NPS Intermountain Region, Forest Service R1-Northern Region, Fish and Wildlife Service Region 6, and US Coast Guard — account for two, one, one, and one award respectively, totaling $127 thousand. Customer concentration is extreme and tied to a single indefinite-delivery contract vehicle.
The vendor holds a single-award Indefinite Delivery Contract (140P8524D0002) with the NPS Pacific West Region, awarded May 21, 2024, with a $500 thousand ceiling running through June 30, 2029. Six task orders have been issued under this IDIQ across the 2024–2026 period for a combined potential value of $272 thousand. Representative delivery orders include $97.6 thousand for above-ground and underground fuel storage tank services at Yosemite National Park (July 1, 2026), $89.1 thousand to fund option year one and service two additional tanks (June 25, 2025), $63.4 thousand for tank services under the base period (May 21, 2024), and $9.45 thousand for fuel sensor probe replacement on an above-ground tank at El Portal, California (May 15, 2026). All work is priced firm fixed-price with no small business set-aside.
Activity remains sparse and infrequent — three awards in 2026, two in 2025, two in 2024, with multi-year gaps before that — reflecting the project-driven, low-volume nature of federal fuel infrastructure maintenance. One award (combined potential value $98 thousand) reaches ultimate completion within the next twenty-four months and faces recompete risk in that window. The vendor operates exclusively as a prime contractor with no subcontract activity across the visible footprint. Capability focus is narrowly scoped to fuel tank systems: monitoring, reporting, maintenance of above-ground and underground tanks; sensor replacement; and related compliance work for hazardous materials storage at national park and federal facility locations.
