Who We Are
The Pima County Department of Environmental Quality's Voluntary No-Drive Days Program (also known as the Clean Air Program) was established in 1989 and is mandated by the omnibus air quality legislation enacted in 1988 (A.R.S. § 49-506) and Pima County Code 17.44.020. In the past, Pima County experienced violations of national air quality standards. To prevent further deterioration, several initiatives were developed to reduce air quality emissions in Pima County. The Voluntary No-Drive-Days/Clean Air Program is one of those initiatives.
The PDEQ Voluntary No-Drive Days/Clean Air Program is also a permanent and enforceable control measure approved into the most recent Carbon Monoxide Limited Maintenance Plan by EPA effective January 20, 2010 [74 FR 67819; 12/21/09]. The principal goals of the Program are to reduce vehicle emissions that contribute to air pollution by increasing public awareness of air quality issues and encouraging alternative modes of transportation and other pollution-reducing activities.
How We Are Funded
The Pima County Clean Air Program is funded by a grant from the Arizona Department of Environmental Quality. In addition, grants from other agencies may help fund the program. No local tax revenue is used to support the Voluntary No-Drive Days/Clean Air Program.
