The purpose of this handbook is to provide a practical guide offering a comprehensive overview of the
department’s policies and interpretations of Rule 310. The intent is that this guide will be useful and used. The handbook is organized to respond to topical questions and it is structured to provide answers to the most commonly encountered compliance challenges.

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 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.

ADOT is the primary decision maker for federal-aid transportation plans and investments in nonmetropolitan areas with populations below 50,000. However, ADOT understands the importance of consulting with local governments before, during and after the decision-making process to ensure participation results in improved transportation system planning, performance and project development. Therefore, ADOT has developed guidelines that outline the consultation process and define how and when outreach will occur with officials from rural areas.

The primary guidelines for state consultation with nonmetropolitan local officials are contained in the FHWA and FTA joint rulemaking, statewide and metropolitan planning: Part 450 Planning Assistance and Standards. (Federal Register: Feb. 14, 2007, Part III). According to 23 CFR 450.210(b), at least once every five years (as of Feb. 24, 2006), the state shall review and solicit comments from nonmetropolitan local officials and other interested parties for a period of not less than 60 calendar days regarding the effectiveness of the consultation process and any proposed changes. A specific request for comments shall be directed to the state association of counties, state municipal league, regional planning agencies or directly to nonmetropolitan local officials.

It is intended that this document is subject to review and revision every five years. In the event that Congress enacts new transportation language, this document will be subject to immediate revision.
