Planning Area Maps
The Interactive Planning Area Map has the following layers:
- Particulate matter less than 10 microns in diameter (PM10) nonattainment area
- Ozone nonattainment area
- Carbon monoxide (CO) maintenance area
- Area A
- County boundaries
- Townships, ranges, and sections
Activating and Deactivating Layers
All layers of the map will be visible when the map is opened. To turn layers of the interactive map on and off, click on ‘Content’ in the upper left.
Then click the checkbox next to the layer(s) that you would like to turn off or on. Note that ‘streets’ is the base map and cannot be turned off.
Zoom In/Out
To zoom in or zoom out, use the roller on your mouse, or use the + and – buttons in the upper left of the map. To return the map to its original size, click the ‘home’ icon.

PM10 Non-attainment Area
8 Hour Ozone Non-attainment Area
Area A was originally drawn by the Arizona Department of Environmental Quality (ADEQ) as the area under which the clean burning gasoline measures (emissions testing, and summer and winter fuel formulations) are applicable. Since then, the boundary has been used by many other state statues, rules and ordinances (such as residential wood-burning) as the area of applicability for those respective regulations.
The area designated by EPA where concentrations of particulate matter less than 10 microns in diameter (PM10) exceed the national standard. PM10 includes dust, soot and other tiny bits of solid materials that are released into and move around in the air. PM10 comes from many sources, including paved and unpaved roads, construction, mining, agricultural activities, wood burning, motor vehicles, power plants, and other types of fuel-burning equipment.
The area designated by EPA where concentrations of ozone exceed the national standard. At ground-level, ozone is the primary constituent of smog. Ozone is not emitted directly into the air but is formed by the reaction of volatile organic compounds (VOCs) and nitrogen oxides (NOX) in the presence of heat and sunlight. VOCs are emitted from a variety of sources, including motor vehicles, chemical plants, refineries, factories, consumer and commercial products, and other industrial sources. Nitrogen oxides are emitted from motor vehicles, power plants, and other sources of combustion.
The area previously designated by EPA where concentrations of carbon monoxide (CO) exceeded the national standard. In 2005, EPA determined that this area attained the national standard for CO, and redesignated the area as a maintenance area instead of a non-attainment area. Carbon monoxide (CO) is an odorless, colorless gas. It forms when the carbon in fuels does not completely burn. Vehicle exhaust contributes roughly 60 percent of all carbon monoxide emissions nationwide, and up to 95 percent in cities. Other sources include fuel combustion in industrial processes and natural sources such as wildfires.
