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.

This Campaign Effectiveness Study, conducted for the Pima County Department of Environmental Quality, was designed to evaluate the specific effectiveness of the 2013-2014 Clean Air and Clean Stormwater Program Campaigns. This project analyzed and tracked the overall effectiveness of the Clean Air Program after 24 campaign sessions. For the second consecutive year, the survey also measured and tracked attitudes, knowledge, awareness, and behaviors related to stormwater management for the Clean Stormwater Program Campaign.

This Campaign Effectiveness Travel Behavioral Study, conducted for the Pima County Department of Environmental Quality, was designed to evaluate the specific effectiveness of the 2012-2013 Clean Air Campaign, as well as analyze the overall effectiveness of the air quality media campaign after 23 campaign sessions. New to the current study, the survey also measured baseline awareness/knowledge related to storm water and hazardous waste issues.

The Neighborhood Reinvestment Program has been in existence since the 1997 Pima County bond election established General Obligation Bond funding for construction of small scale capital improvement projects to be selected through a neighborhood consensus process. Specific projects are recommended by the citizen committees to the Board of Supervisors for final approval.

The purpose of this Pima County roadway project is to improve operations on Colossal Cave Road within the project limits while being sensitive to the surrounding environmental features and land uses. Potential impacts of the project are on the historic adobe building; the historic Shrine of the Santa Rita property during construction on biological resources, utilities, access, traffic operations, noise, and air quality.

The primary purpose of this study is to determine what transportation improvements would be needed to accommodate future growth and development of the Raytheon Missile Systems facility located south of Tucson International Airport on Hermans Road. A secondary purpose of this study is to consider longer-term roadway and transit improvements that will improve access to Tucson International Airport and associated airport property planned for future development. Specifically, the study analyzed the effects of closing Hughes Access Road/Alvernon Way to non-Raytheon traffic and recommends alternative roadway improvements that would be needed to accommodate this closure.

Pima County’s Southwest area has been identified by County planners as a potential and strategic growth area. To accommodate population growth, the existing infrastructure must be improved and expanded. The purpose of this Infrastructure Plan is to provide a basis for infrastructure decision-making related to development in the Southwest area. It quantifies the nature, phasing, financial impacts, and funding possibilities for those flood control, parks and recreation, transportation, wastewater infrastructure and other improvements that are necessary to service future saturation growth within the study limits.
