What the agency says

The Environmental Protection Agency (EPA) is taking final action on a source-specific revision to the Maricopa County Air Quality Department's (MCAQD or "Department") portion of the Arizona State Implementation Plan (SIP). This revision consists of certain permit conditions related to emissions offsets generated from the replacement of existing diesel-fueled solid waste collection trucks promulgated by the MCAQD and submitted by the State of Arizona for inclusion in the Maricopa County portion of the Arizona SIP under the Clean Air Act (CAA or "Act"). The permit conditions were submitted for SIP approval to ensure that they are federally enforceable, which is the basis for qualifying certain emissions reductions as creditable offsets under the CAA.
