West Pinal Nonattainment Area

In 2012, the U.S. Environmental Protection Agency (EPA) designated a large portion of Pinal County as a moderate nonattainment area for particulate matter pollution, also known as PM10, due to monitor violations of federal air quality standards for particulate matter. In 2020, EPA redesignated the nonattainment area to Serious due to ongoing PM10 exceedances. 

The ground disturbance caused by construction activities, general earthmoving activities, and windy conditions result in particulate matter emissions. The construction rules were needed in order to achieve emission reductions for the West Pinal PM10 Nonattainment Area.
