UNSPSC 77121506: Methane monitoring

UNSPSC 77121506 Methane monitoring is a Commodity code that state and local governments use to classify procurement of specialized atmospheric detection and monitoring equipment, testing services, and infrastructure maintenance related to methane and other gaseous contaminants. Recent state and local solicitations show this code applied inconsistently across a broad spectrum of environmental monitoring work—from dedicated methane detection system maintenance at transportation facilities to water quality testing for lead and mold contamination, air quality monitoring station operations, and even unrelated services such as backflow testing and propane tank installation. The actual buying activity under this code spans equipment service and calibration contracts, facility-based monitoring system maintenance, and environmental consulting services for indoor air quality and gaseous hazards. Issuing bodies include transit authorities, state environmental agencies, county waste management departments, municipal utilities, and county facilities management divisions, with repeat solicitation activity from state environmental quality commissions and regional transportation authorities.

Recent opportunities show geographic spread across California, Texas, Michigan, Florida, Nevada, Georgia, and South Carolina, with Texas and California appearing most active. The Orange County Transportation Authority (OCTA) issued IFB 250322 for methane detection system service and maintenance across five facilities, due June 1, 2026, under a prevailing-wage contract with estimated value of $260,000 over four years. The Texas Commission on Environmental Quality (TCEQ) issued multiple air quality monitoring station operation and maintenance solicitations (RFP 582-27-00007 and 582-27-00014) for PM2.5 and multi-pollutant continuous monitoring, due June 29, 2026 and April 9, 2026 respectively, with firm pricing and 85 percent quarterly data return performance requirements. The Michigan Department of Technology, Management & Budget issued RFP 26_2065 for industrial hygiene consulting and inspection and sampling of lead, mold, asbestos, and air contaminants statewide, due June 29, 2026, requiring AIHA and NVLAP certifications. The Nevada State Purchasing Division issued RFP 70CNRS3879 for WIIN water testing in schools and daycares, due July 8, 2026, valued at $528,535 over two years with emphasis on lead testing in low-income facilities. Bidders pursuing this code should note that recent opportunities frequently misclassify work—several lead and mold inspection, water testing, and atmospheric corrosion services solicitations appear tagged to this methane code despite limited methane-specific scope, suggesting the code is underutilized and many genuine atmospheric monitoring opportunities may be filed elsewhere.
