EPA is proposing to determine that the Rillito moderate PM-10 nonattainment area in Arizona attained the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10) by the applicable attainment date. In addition, EPA proposes to find that the Rillito area is currently attaining the PM10 standards, and based on this latter finding, EPA is proposing to determine that certain Clean Air Act requirements are not applicable for so long as the Rillito area continues to attain the PM10 NAAQS. Lastly, EPA is proposing to correct an error in a previous rulemaking that involved the classification of PM10 nonattainment areas within the State of Arizona.
