The purpose of the ambient air monitoring network is to sample air pollution in a variety of settings, assess the health and welfare effects, and assist in determining sources of air pollution. In general, six basic monitoring objectives and five measuring scales are used to determine the network design. Since it is physically and fiscally impossible to monitor the air in every location, representative samples must be obtained. These samples are determined by using the monitoring objectives and the spatial measurement scales. The network must be dynamic enough to maintain a current representative sample of the air quality. Air quality issues such as eight-hour ozone non-attainment boundaries and permits for new sources are diverse and controversial subjects for the citizens of Maricopa County. With its robust air monitoring network and mobile monitoring tools, the department strives to provide the most reliable and relevant air monitoring data to the public.

The Arizona Department of Transportation, in coordination with Apache County District II and the Fort Defiance Chapter of the Navajo Nation, analyzed the traffic circulation conditions of Navajo Routes 7, 12, 54, 110, and 112 within the Fort Defiance Industrial Area which is designated as a major growth area on the Navajo Nation. The study was funded by the Federal Highway Administration’s State Planning and Research Program and administered through ADOT’s Multimodal Planning Division's Planning Assistance for Rural Areas (PARA) program. The study was initiated to develop a planning strategy to improve the mobility and safety within the Fort Defiance Industrial Area.

This bond funded program differs significantly from other County capital improvement projects which typically include detailed information specific to each project when the bond proposals were developed. It utilizes its designated bond funding for specific community based projects via an open and continuous application process and under the oversight of advisory bodies appointed by the Pima County Board of Supervisors.

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.
