About NIGP 40513
NIGP Item 40513 Gas, Natural (Including Compressed Natural Gas) encompasses procurement of natural gas commodity supply, CNG fueling infrastructure maintenance and operation, natural gas distribution system construction, and renewable natural gas facility upgrades by state and local government. State and local buyers are acquiring three distinct service lines under this code: (1) natural gas commodity supply and delivery to facilities, typically through retail energy suppliers on fixed-price or indexed terms; (2) compressed natural gas fueling station maintenance, repair, and operations supporting municipal and transit fleet vehicles; and (3) natural gas distribution main construction, abandonment, and relocation work performed by licensed contractors meeting API standards. Issuing bodies span school districts (Cobb County School District, Fayette County Public Schools, Bartow County School System), counties (Sacramento County, Hillsborough County Public Schools, Dane County, Rockland County), cities (Salt Lake City, Tucson, Leesburg, Trion), and regional transit authorities (Orange County Transportation Authority). Sacramento County and Salt Lake City appear as repeat buyers issuing RFPs for CNG facility maintenance within the past two months.
Recent solicitations show geographic spread across the Southeast (Georgia, Florida), Southwest (Arizona, Utah), Midwest (Wisconsin), and West Coast (California), with school district natural gas supply representing a concentrated buyer segment. Representative opportunities include Sacramento County RFP 2026RFP0441 (CNG station preventative maintenance and repair at two sites, RFP due October 16, 2026); Salt Lake City RFP SLCI27027 (CNG time-fill fueling system maintenance and 24/7 remote monitoring, proposals due November 4, 2026); Orange County Transportation Authority RFP 250282 (turn-key CNG fueling station operation and maintenance at three bus bases serving 481 buses, $2,181,165 contract value over three years, proposals due July 8, 2026); Dane County RFP 326024 (renewable natural gas facility replacement and upgrade from landfill gas sources, proposals due September 3, 2026); and City of Leesburg IFB 26-002-HG (1,500 feet of 6-inch natural gas main installation and turnpike boring, bids due November 5, 2025). Hillsborough County Public Schools ITB 26205-ITB-DST awarded fuel supply for approximately 1.75 million gallons annually of ultra-low sulfur diesel at an estimated contract value of $5.5 million with nine competitive bids received. School districts and counties frequently structure gas supply contracts with annual renewal options; CNG infrastructure work typically carries prevailing wage and insurance requirements; and transit authorities require FTA compliance and dedicated HSE management.
