Sustainable Environment

Pima Association of Governments’ Sustainable Environment Program supports the long-term environmental, economic and social vitality of our community. The program serves as a resource for watershed and air quality planners and coordinates partnership building among stakeholders in the region and state.

PAG works with local governments, state and federal agencies, citizen and interest groups on a variety of issues including water resource and quality issues, air quality, wildlife and habitat, invasive species, recycling and low impact development. 
PAG has key environmental responsibilities both as the designated water quality planning agency under Section 208 of the Clean Water Act and as the designated lead air quality planning organization in compliance with the Clean Air Act.
PAG works to ensure proper planning of wastewater treatment facilities throughout the region and assists local municipalities with stormwater regulatory compliance.  

PAG assesses regional air pollution through air quality modeling that also provides input into PAG’s 5-year transportation improvement program (TIP) and the long-range regional transportation plan (RTP. In addition, PAG researches and assesses the levels of air pollutants and greenhouse gases in the region.
