The intent of this guide is to:
• Provide agricultural operators with information and guidance on how to effectively implement individual best management practices.
• Inform the general public about the efforts Maricopa County farmers are implementing to improve air quality.
• Provide Natural Resource Conservation Districts and other farm organizations with background information regarding the agricultural PM10 general permit.
• Provide regulators with information and guidance on how to determine compliance with the agricultural PM10 general permit.

The intent of this guide is to provide information and guidance on how to effectively implement best management practices. It is based on the best information currently available; later publications may be issued to update this document. This guide represents the first step in helping farmers reduce PM10 emissions from farmlands located within the Maricopa County PM10 non-attainment area.

A landmark assessment of infrastructure needs in Arizona was produced by the L. William Seidman Research Institute in May 2008 for the Arizona Investment Council (AIC): "Infrastructure Needs and Funding Alternatives for Arizona: 2008-2032", that addressed infrastructure needs in four categories: energy, telecommunications, transportation, and water and wastewater. The information from the AIC report is a major input to the report that follows. Other types of infrastructure — most notably education, health care, and public safety — also are analyzed here to provide a more complete picture of infrastructure needs in Arizona. The goals of this report are to place Arizona’s infrastructure needs into national and historical contexts, to identify the changing conditions in infrastructure provision that make building Arizona’s infrastructure in the future a more problematic proposition than in the past, and to provide projections of the possible costs of providing infrastructure in Arizona over the next quarter century.
