UNSPSC 77121500: Air pollution

UNSPSC 77121500 Air pollution is a Class code encompassing environmental compliance consulting, air quality permitting and regulatory support, emissions testing and monitoring, and related technical services that state and local governments procure to meet federal and state air quality requirements. Recent solicitations show state and local agencies purchasing three primary service categories: environmental consulting for airport and facility air quality compliance (NPDES permitting, wildlife hazard assessments, petroleum storage tank services, hazardous materials management); professional air quality permit development and regulatory compliance support for air districts and municipalities (permit application processing, emissions calculations, health risk assessments, AB 2588 Air Toxics Program support); and operational air emissions and stack testing services to verify compliance with EPA methods and facility air permits (RATA testing, MATS particulate testing, visible emissions testing, continuous ambient air monitoring). The issuing bodies span state environmental agencies (Texas Commission on Environmental Quality, Tuolumne County Air Pollution Control District), county transportation and aviation departments (Broward County Aviation Department), water utilities (Orlando Utilities Commission), cities and towns (Phoenix Water Services, Simsbury), and county governments (Rockland County). Broward County Aviation Department appears as a repeat buyer within the recent window, with both a draft and final RFP for environmental compliance services at two airports.
