Pima County Department of Environmental Quality monitors ambient (outdoor) air pollutants throughout eastern Pima County, including the Tucson metropolitan area and Green Valley. There are six principal pollutants, called “criteria” pollutants that are monitored in accordance with the National Ambient Air Quality Standards set by the Environmental Protection Agency to comply with the Federal Clean Air Act. These standards were established to protect public health and the environment from harmful levels of air pollution.

The Pima County Department of Environmental Quality has prepared this document to be submitted to the U.S. Environmental Protection Agency, Region IX. The purpose of the Ambient Air Monitoring Network Plan is to determine if the network is achieving the air monitoring objectives specified in 40 CFR Part 58 Appendix D, which mandate adherence to certain number, type and location requirements of monitoring sites and specific site criteria such as monitoring inlet height. The review should also determine if modifications should be made to the network (e.g. through the termination or relocation of unnecessary stations or addition of new stations). In addition, the review is necessary in order to ensure that the residents of Pima County are provided adequate, representative and useful air quality data, and to provide adequate protection to public health.

The Old U.S. Highway 80 Area Plan is an entirely new plan which removes portions of the State Route 85 Area Plan and the Tonopah/Arlington Area Plan. It is important to note that this Plan is not a document that represents final buildout as many municipal general plans typically do. Rather, it prepares for and accommodates growth over the next ten to fifteen years, but will be reexamined and updated as necessary to reflect current conditions and changes. While not a complete solution, the Plan helps address the effects of growth and development by enhancing cooperation between government agencies, citizens, and other affected interests, and by considering regional implications.

It is important to note that the Rio Verde Foothills Area Plan is not a document that represents ultimate buildout as many municipal general plans typically do.

While not a complete solution, the Rio Verde Foothills Area Plan helps address the effects of growth and development by enhancing cooperation between government agencies, citizens, and other affected interests, and by considering regional implications.
