Pima Association of Governments supports the long-term environmental, economic and social vitality of our community through collaborative water and air quality planning.

PAG serves as the designated water quality planning agency under Section 208 of the federal Clean Water Act and works to ensure proper planning of wastewater treatment facilities throughout the region and assists local municipalities with stormwater regulatory compliance.

As the designated lead air quality planning organization in compliance with the federal Clean Air Act, PAG assesses regional air pollution through air quality modeling to inform planning for PAG’s 5-year transportation improvement program (TIP) and long-range regional mobility and accessibility plan (RMAP). PAG also researches and quantifies the levels of air pollutants and greenhouse gases in the region.

Through its Travel Reduction and Sun Rideshare programs, PAG promotes alternative transportation to improve air quality and traffic congestion to support clean air. PAG also promotes clean energy and the use of alternative-fuel vehicles to support environmental sustainability and economic vitality.

In addition, PAG serves as a resource and collaboratively works with other regional and state stakeholders to address water and air quality planning issues and solutions, ranging from green infrastructure development to researching impacts on wildlife and habitat

PAG also encourages watershed restoration through a non-profit program in the Center for Pima Basin Sustainability, which is managed by PAG.
