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.
