This inventory includes emissions of coarse particulate matter <10 µm in diameter (PM10), fine particulate matter < 2.5 µm (PM2.5), nitrogen oxides, sulfur oxides, and ammonia. Emissions are calculated for both Maricopa County and the PM10 nonattaiment area. Annual totals as well as typical daily emissions are provided for all source categories.

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.

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 Federal Transit Administration Section 5311 Rural Public Transportation Program provides program funds for capital, operating, and administrative assistance to local public bodies, nonprofit organizations, and operators of public transportation services in non-urbanized areas. The Public Transportation Division of the Arizona Department of Transportation provides financial and technical assistance to transit agencies throughout the state to enhance the access of people in non-urbanized areas to health care, shopping, education, employment, public services and recreation.

The Arizona Department of Transportation was authorized in 1996 to administer a State Infrastructure Bank under a cooperative agreement with the Federal Highway Administration. The Highway Expansion and Extension Loan Program (HELP) was established. The financial statements present only the funds comprising the Fund and are not intended to present fairly the financial position or results of operations of the Department.

This document is designed to improve compliance with Maricopa County air pollution rules and regulations, with particular emphasis on Rule 310, which deals with fugitive dust sources, a major source of PM-10. It also describes control measures and work strategies that will assist in ensuring compliance with Rule 310. Also included in this report is a glossary of terms, a brief summary of applicable County air pollution regulations, and detailed information on the requirements for implementation of dust control practices.
