UNSPSC 77121503: Air pollution protection services

UNSPSC 77121503 Air pollution protection services (Commodity) spans environmental compliance support tied to air quality monitoring, emissions inventory development, and regulatory permitting work that state and local governments increasingly solicit as climate and Clean Air Act obligations intensify. Recent opportunities show state environmental agencies, regional planning councils, and municipal governments hiring consultants to operate continuous air monitoring stations, develop greenhouse gas emissions inventories tied to climate action planning, and support NEPA and air quality permitting on transportation and infrastructure projects. The Georgia Department of Transportation (GDOT) is actively sourcing environmental support services including air quality and noise studies; the Texas Commission on Environmental Quality (TCEQ) has posted two separate RFPs for operation and maintenance of PM2.5 continuous monitors across multiple sites in South Texas; and Rockland County (New York) is procuring greenhouse gas emissions inventory and climate action planning services. Work under this code typically requires qualified environmental consultants with expertise in air quality modeling, monitoring equipment operation and maintenance, emissions data analysis, regulatory compliance, and NEPA documentation—commonly delivered through professional services contracts under RFP, RFQ, or RSQ notice types with response windows of 30 to 60 days.

Geographic activity clusters in Texas (TCEQ monitoring contracts), California (California Air Resources Board greenhouse gas modeling and scenario evaluation work), Georgia (GDOT environmental services), and New York (Rockland County climate planning), with secondary activity in Florida and Arizona. Recent representative opportunities include GDOT's RFQ PE48401RFQ2026000000601 (due August 17, 2026) for environmental support across NEPA, air quality, noise, and public involvement; TCEQ's RFP 582-27-00007 for operation and maintenance of a PM2.5 monitoring station at Big Bend National Park (contract term September 2026 through August 2028, firm fixed price with no escalation, 85 percent quarterly data return requirement, and up to 25 percent payment reduction for failure); and Rockland County's RFP-RC-2026-016 (proposals due June 30, 2026) for a two-year greenhouse gas emissions inventory and climate action plan with three optional one-year renewals, weighted evaluation emphasizing MWBE participation at 100 of 1,000 points. TCEQ contracts carry HUB (Historically Underutilized Business) subcontracting goals of 1.0 percent and are federally funded; GDOT work is state-funded with communication restrictions during the RFQ phase; Rockland County work carries optional MWBE/DBE/SDVOB weighting and requires professional liability insurance with $1,000,000 per occurrence limits.
