Letter from Carl Hayden to C. H. Akers on the opposition to the Grand Canyon bill from A. A. Johns, J. W. Sullivan, Jesse Hoyce, T. E. Cureton, and Hugh Campbell. Hayden mentions his failure to contact the governor before the present special session, but expresses hope of the legislature passing a memorial on the subject.

Communities, states, and countries all over the world are using a type of reporting called "state of the environment" to provide a summary of the status and trends of key natural resources across and within various regions. Specifically, the purpose of a state of the environment report is to describe and monitor the health of the environment in terms of key indicators.

In a rule published July 2, 2002, EPA found the Arizona Department of Environmental Quality’s "Plan for Attainment of the 24-Hour PM10 Standard – Maricopa County PM10 Nonattainment Area" (May 1997), inadequate to achieve attainment of the 24-hour National Ambient Air Quality Standards for particulate matter 10 microns or fewer in aerodynamic diameter (PM10) at the Salt River monitoring site. The 1997 ADEQ SIP revision included attainment and Reasonable Further Progress demonstrations for the 24-hour NAAQS at the Salt River air quality monitoring site of the Maricopa County PM10 Serious Nonattainment Area, as well as at three other monitoring sites in the Phoenix area, - the Maryvale, Gilbert, and West Chandler sites. On August 4, 1997, EPA approved ADEQ’s attainment and RFP demonstrations for the Salt River monitoring area, which showed that the 24-hour PM10 NAAQS would reach attainment in the area by May 1998. Due to continuing violations of the 24-hour PM10 NAAQS at the Salt River air quality monitoring site since May 1998, EPA subsequently required Arizona to submit a revision to correct SIP inadequacies. This document consists of Arizona’s revisions to the state implementation plan for the Maricopa County PM10 Serious Nonattainment Area as described by EPA in its Federal Register notice of disapproval.

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.

The Governor’s Executive Order in 2007 directed the Arizona Invasive Species Advisory Council to develop an invasive species management plan by June 30, 2008. This plan is based upon the framework recommended in the initial AISAC report and focused on five strategic concepts: Leadership and Coordination, Research and Information Management, Anticipation and Outreach, Control and Management, and Funding. In developing the plan, fifteen objectives and sixty-three recommendations were established to address invasive species needs in Arizona.

On February 2, 2005, Governor Janet Napolitano signed Executive Order 2005-02 establishing the Climate Change Advisory Group. It directed the CCAG, under the coordination of the Arizona Department of Environmental Quality (ADEQ), to:
1) prepare an inventory and forecast of Arizona greenhouse gas (GHG) emissions; and
2) develop a Climate Change Action Plan with recommendations for reducing GHG emissions in Arizona.
