NIGP 43030: Gases, Radioactive Counting: Methane, Pr-Gas, Q-Gas, etc.

NIGP 43030 Gases, Radioactive Counting: Methane, Pr-Gas, Q-Gas, Etc., an Item code, encompasses compressed natural gases, methane detection and monitoring systems, and associated testing and calibration services that state and local government agencies procure for operational, safety, and environmental compliance purposes. Recent solicitations show state and local buyers using this code to source compressed natural gas for vehicle fleets, maintain methane detection and monitoring equipment at transportation and utility facilities, and conduct environmental surface emissions monitoring at landfills. Issuing bodies include transit authorities, state departments of transportation, county environmental agencies, and municipal water utilities. The Orange County Transportation Authority has posted two recent solicitations under this code—one for test and operation gases for compressed natural gas (CNG) buses and facilities (IFB 260542, due October 27, 2026, with a $100,000 budget for two years) and another for methane detection system service and maintenance across five OCTA facilities (IFB 250322, with a $260,000 budget for four years). Both OCTA solicitations are prevailing-wage contracts subject to Davis-Bacon requirements and Disadvantaged Business Enterprise participation goals.

Recent activity concentrates in California and Washington. Sacramento County released an RFP for methane surface emissions monitoring services at Kiefer Landfill using alternative technologies such as drones and remote sensing (RFP 2026-PURB RFP-0083, proposals due September 16, 2026), and the City of Phoenix Water Services Department solicited sealed offers for fixed atmospheric monitoring instruments to detect hazardous gases at water and wastewater facilities (IFB-27-0435, offers due September 4, 2026, with a five-year term and DBE-Neutral program requirements). The Washington State Department of Transportation, on behalf of Washington State Ferries, posted an RFP for occupational medical surveillance services (RFP20260825, proposals due October 9, 2026), which while not directly aligned with gas procurement, appears to have been cataloged under this code and represents broader environmental and occupational safety monitoring. Contracts awarded under this code typically require compliance with federal and state air quality regulations (40 CFR Part 60, California Air Resources Board standards), Davis-Bacon prevailing wage requirements in federally funded transportation contexts, and comprehensive insurance including general liability, automobile liability, and workers' compensation coverage.
