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.

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.

This handbook describes the requirements for a licensed motor vehicle dealer to operate a fleet emissions inspection station. Contained within are: Summarizations of the fleet emissions inspection station permitting and inspector licensing processes; lists of required inspection equipment and equipment maintenance/calibration standards; inspection procedures for specific classes of vehicles; record keeping procedures. The inspection procedures outlined in this handbook apply to vehicles specifically held for retail sale. Vehicles other than those held for retail sale (parts truck, courtesy van, loaner vehicle) must be inspected at an official state emissions inspection station. Because dealers typically do not own the required equipment and apply for a permit to inspect diesel powered vehicles, this handbook does not address their inspection. The handbook was developed from laws and regulations found in Arizona Revised Statutes Title 49, Chapter 3, Article 5, and Arizona Administrative Code, Title 18, Chapter 2, Article 10.

This handbook describes the fleet emissions inspection station requirements for all entities other than licensed motor vehicle dealers. Contained within are: Summarizations of the fleet emissions inspection station permitting and inspector licensing processes; lists of required inspection equipment and equipment maintenance/calibration standards; inspection procedures for specific classes of vehicles; record keeping procedures. The handbook was developed from laws and regulations found in Arizona Revised Statutes Title 49, Chapter 3, Article 5, and Arizona Administrative Code, Title 18, Chapter 2, Article 10.

This handbook describes the fleet station permitting process, the types of permits and inspector licenses that are issued, required inspection equipment and equipment maintenance, inspection procedures for specific classes of vehicles, and record keeping procedures. The handbook was developed from laws and regulations found in Arizona Revised Statutes Title 49, Chapter 3, Article 5, and Arizona Administrative Code, Title 18, Chapter 2, Article 10.

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.

A series of small earth movements occurred along the slopes of State Route 87 at about mile marker 224 (between the Bush Highway and Route 188) throughout the winter of 2007‐2008, culminating with a landslide on Friday, 21 March 2008. This landslide buckled the southbound lanes, displaced the northbound lanes, and closed the highway for nearly a week. The mass movements occurred on slopes that were constructed with re‐vegetated, laid back slopes; soil nail walls; and rip rap‐lined channels. However, our reconnaissance mapping indicates that most, if not all, of the slope movements are located within a much larger, older landslide adjacent to, and cut by, SR‐87. No specific trigger for the landslides was immediately apparent, although a combination of factors (e.g., precipitation, groundwater levels, etc.) may have contributed to conditions for the slope failure. Headscarps of various types of landslides are present along both sides of the highway. Results from our preliminary investigation indicate that up to three other paleo‐landslides may be present in the immediate vicinity. The full extent and nature of these landslides are unknown and require further investigation to evaluate their potential to be reactivated and risk they pose to the highway.

This field trip guide was created for a Project WET conference held in Tucson, Arizona, June, 2007. This guide discusses the general geology of the Santa Catalina Mountains in Sabino Canyon, and points out evidence of the July 2006 floods and debris flows. There are stops in the first few miles of canyon, and towards the end of the tram road, where the most spectacular debris flows are located.
