The purpose of this handbook is to promote appropriate, consistent, and timely evaluations of compliance and initiation of enforcement by the Arizona Department of Environmental Quality. This handbook describes a uniform system for pursuing and escalating enforcement. It serves as a road map for new ADEQ compliance and enforcement staff, and a desk reference for those with more experience. It also provides guidance to those local authorities that have undertaken compliance and enforcement responsibilities through a delegation agreement with ADEQ. All of the concepts within ADEQ’s Compliance and Enforcement Policy, along with a number of other ADEQ compliance and enforcement related policies, have been incorporated into this handbook either explicitly or through the development of boilerplate.

In March 2000, Governor Jane Hull convened the Brown Cloud Summit to examine methods to improve visibility in the Phoenix Metropolitan Area. As part of this Summit, a Visibility Standards Subcommittee was established to recommend methods for measuring visible air quality and tracking improvements in visible air quality over time. Based on its research, the Visibility Standards Subcommittee recommended that a visibility index be established through a public survey process representative of a cross-section of residents. Acting on the recommendation, ADEQ established the Visibility Index Oversight Committee. The Committee’s goal was to coordinate the involvement of Phoenix-area residents in the development of a visibility index.

For two and a half decades, the men and women of ADEQ have dedicated themselves to the noble cause of environmental stewardship. They have helped us respect the delicate balance between the natural world and the people who depend on it for sustenance, prosperity and a rewarding quality of life. Most importantly, they have served diligently and passionately to conserve and protect Arizona's natural bounty for generations to come.
