NIGP 40502: Alternative Fuels (Not Otherwise Classified)

NIGP 40502 Alternative Fuels (Not Otherwise Classified), an Item code, encompasses bulk fuel supply, delivery, and equipment services that state and local governments procure for fleet operations, transit agencies, and specialized fueling infrastructure. Recent solicitations show counties, cities, transit authorities, and school districts sourcing unleaded gasoline, diesel, biodiesel, renewable diesel, diesel exhaust fluid (DEF), marine fuel, compressed natural gas (CNG), liquid petroleum gas (LPG), and hydrogen at scale. Issuing bodies span county departments (Solano, Madison County, Sarasota, Cobb County), municipal transit authorities (Orange County Transportation Authority, City of Austin), school districts (Cobb County, Paulding County), and independent transit operators (Sun Tran, Madison County Mass Transit). The City of Austin is soliciting bulk motor fuels across 130 tank locations citywide with an estimated annual volume of 5 million gallons; Sarasota County is rebidding marine fuel supply from a waterfront dispensing facility for approximately 8,000 gallons annually; and Orange County Transportation Authority is procuring hydrogen mobile fuelers ($5.872 million initial term) and CNG fueling station operation and maintenance ($2.181 million three-year term) to support transit fleets. Pricing benchmarks commonly reference the Oil Price Information Service (OPIS) daily rack index with fixed delivery markups or markdowns, and contracts typically include insurance, delivery performance, tank monitoring, and compliance requirements tied to ASTM, CARB, or SAE standards.

Geographic concentration appears heaviest in California (Orange County Transportation Authority, Sacramento County, City of Austin/Texas, Solano County), with secondary activity in Florida (Sarasota County), Illinois (Madison County Mass Transit), Arizona (City of Peoria, Tucson), Georgia (Cobb County School District, Paulding County School District), and Washington State (Department of Enterprise Services statewide procurement). Representative recent opportunities include the City of Austin IFB 7800 MLJ1046 for bulk motor fuels and fuel-related products and services with proposals due October 29, 2026; Sarasota County IFQ 262916KR (rebid) for marine fuel with quotes due October 9, 2026; Orange County Transportation Authority RFP 260461 for two hydrogen mobile fuelers with proposals due September 15, 2026; Madison County Mass Transit indefinite-delivery contract for B11 biodiesel and unleaded gasoline with bids due October 20, 2026; and the Washington State Department of Enterprise Services statewide bulk lubricants, greases, and DEF supply contract with bids due July 30, 2026. Local business preferences, small business set-asides, and DBE participation goals appear in several solicitations, particularly in California and federal-grant-funded transit contracts.
