About UNSPSC 15111502
UNSPSC 15111502 Methane, a Commodity code, encompasses detection system service, maintenance, and calibration work that state and local governments buy to monitor and manage methane emissions across facilities and fleets. Recent solicitations show the code capturing both ongoing operational maintenance contracts for existing detection infrastructure and analytical support work related to emissions tracking and climate policy compliance. Issuing bodies include transit authorities, community colleges, and state environmental agencies, with no single repeat buyer dominating the recent pipeline but a clear mix of operational facility management and policy-support procurement.
The Orange County Transportation Authority (OCTA) issued IFB 250322 in June 2026 for methane detection system service and maintenance across five facilities—Garden Grove Base, Anaheim Base, Irvine Sand Canyon Base, Santa Ana Base, and Laguna Hills Transportation Center—covering triannual calibration, functionality testing, unscheduled labor, and repair parts on SEC-3100 and General Monitor IR5000 equipment over a four-year term valued at $260,000, with a hybrid pre-bid conference held May 11, 2026 and bids due June 1, 2026. The California Air Resources Board (CARB) and the State of California also posted RFPs in March and April 2026 for greenhouse gas reduction scenario modeling and evaluation services supporting SB 32 and AB 1279 climate targets, with proposal deadlines of March 30, 2026 and April 20, 2026 respectively. Activity is concentrated in California, with the OCTA contract showing prevailing wage and DBE requirements typical of transit authority procurement, while state-level climate modeling work offers DVBE and small-business preference opportunities. Two welding-materials solicitations from Collin College in Texas (posted July 2026, bids due March and April 2024) were tagged with the code but represent unrelated procurement; the code's recent relevant activity is limited to the three methane-specific opportunities above.
