UNSPSC 77121502: Transboundary air pollution management or control services

UNSPSC 77121502 Transboundary air pollution management or control services is a Commodity code covering regulatory compliance testing, monitoring, and consulting services that state and local governments procure to meet federal and state air quality standards. Recent solicitations show state and local bodies purchasing air emissions stack testing, atmospheric monitoring equipment installation and maintenance, environmental compliance consulting tied to air quality permitting, and greenhouse gas emissions inventories. The Broward County Aviation Department's RFP for environmental compliance services at Fort Lauderdale-Hollywood International Airport and North Perry Airport (PNC2131298P1, proposals due November 5, 2026) exemplifies the consulting work: NPDES compliance, air quality and fuel sampling, analytical laboratory services, and on-call environmental compliance support across two airport facilities under a work-authorization-based engagement structure with up to two consultants selected. The Orlando Utilities Commission's procurement for Air Emissions and Stack Testing Services (RFP 8942, due February 4, 2026) represents the testing side, covering annual compliance testing, Relative Accuracy Test Audits, MATS particulate testing, and visible emissions testing across multiple power generation facilities. Issuing bodies are mixed—county aviation departments, municipal utilities commissions, state departments of transportation, and county/city environmental or facilities authorities all solicit under this code, often with FAA or EPA funding embedded in the scope.

Geographic activity centers on Florida (Broward County, Orlando), Georgia (GDOT environmental support contracts), Texas (TCEQ Big Bend PM2.5 monitoring station, H-GAC procurement consortium activities), Arizona (City of Phoenix atmospheric monitoring), and New York (Rockland County greenhouse gas planning). The Texas Commission on Environmental Quality's Big Bend PM2.5 station operation and maintenance contract (RFP 582-27-00007, due March 23, 2026) and the City of Phoenix's IFB for atmospheric monitoring instruments at water and wastewater facilities (IFB-27-0435, due September 4, 2026) reflect the equipment and ongoing-service side of the market. The Georgia Department of Transportation's three environmental support services contracts (RFQ-484-081726, statements of qualifications due August 17, 2026) bundle air quality work within broader environmental disciplines—Contract 1 explicitly covers air quality, noise, and public involvement. Rockland County's greenhouse gas emissions inventory and climate action plan procurement (RFP-RC-2026-016, due June 30, 2026) signals growth in municipally driven climate compliance and planning work under this code's scope. Federal funding and DBE or MWBE participation requirements appear across most solicitations.
