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.

The Lower San Pedro Groundwater Basin (LSP) baseline groundwater quality study was conducted by the Arizona Department of Environmental Quality in 2000. Located in southeastern Arizona, this semiarid basin is drained by the San Pedro and Gila Rivers. The LSP is a rural landscape with scattered towns and two
extensive copper mining and processing operations. Groundwater from three aquifers (floodplain, unconfined basin-fill, and confined basin-fill or artesian) and fractured mountain hardrock is the principle source of water supply. For this study, 63 groundwater sites were sampled for inorganic constituents. In addition, fewer sites were also sampled for Volatile Organic Compounds (25), radiochemistry (19), radon (19), and pesticide (2) analyses. Eighteen (18) percent of sample sites had concentrations of at least one constituent that exceeded a health-based, Federal or State water-quality standard.

In pursuing its mandated mission to characterize groundwater quality in the state, the Arizona Department of Environmental Quality has collected samples from 1,477 sites over a 15-year period between 1995 and 2009. The sample sites consisted mainly of domestic, stock, irrigation and municipal wells and, to a lesser extent, springs used predominantly for watering stock and wildlife. Sampling activity was conducted within 35 of the state’s 51 officially designated groundwater basins and covered much of Arizona with the exception of Native American tribal lands. The data provide comprehensive and reliable information on the occurrence and concentrations of groundwater contaminants. This is critical knowledge for the estimated 100,000 private domestic wells in the state whose owners represent about 5 percent of Arizona’s population.
