NIGP 43020: Filters, Natural and LPG Gas

NIGP 43020 Filters, Natural and LPG Gas, Item code, encompasses the supply of industrial gases—compressed natural gas, argon, helium, nitrogen, and refrigerants—to state and local operating facilities, transit fleets, and laboratories. State and local buyers under this code procure gases for vehicle fueling systems (particularly CNG bus fleets), laboratory testing and operations, heating and cooling systems, and environmental remediation services. The issuing bodies span transit authorities, environmental agencies, county purchasing offices, and special-purpose districts, often as part of multi-year supply or service contracts with firm pricing and delivery requirements.

Recent activity shows gas supply and extraction services concentrated in California, Illinois, New York, Arizona, and Washington. The Orange County Transportation Authority issued IFB 260542 on October 8, 2026, for test and operation gases for CNG buses and facilities, with bids due October 27, 2026 and a $100,000 budget across a two-year term; the procurement requires F.O.B. destination delivery to two facilities in Garden Grove and Santa Ana, California, with Davis-Bacon prevailing wage and DBE participation mandates. The Illinois Environmental Protection Agency solicited argon, helium, and nitrogen gases (Solicitation 27-532EPA-LAB53-B-53761, due September 10, 2026) for laboratory operations at 825 North Rutledge, Springfield, with a five-year initial term and U.S. manufacturing requirement. The City of Tucson Environmental and General Services Division issued RFP 240011 for EPA-certified refrigerant extraction and gas removal services at its sustainability campus, with extraction required at minimum every two weeks and proposals due September 19, 2024. The County of Rockland posted an IFB for interruptible natural gas supply (due July 29, 2026) as a cooperative purchase with Rockland Community College. Hazmat delivery compliance, regulatory certifications (EPA for refrigerants, board certification in occupational medicine for related services), and insurance minimima (typically $1 million general liability) are standard contract requirements.
