Description: 

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Maricopa County Air Quality Department's (MCAQD) Rule 510 as part of the Arizona State Implementation Plan (SIP). These rule revisions concern revisions to the maximum levels of ambient air pollution for the protection of public health and welfare. We are proposing to approve this rule to regulate these emissions under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
