ADEQ welcomes comments during this second comment period and public hearing on the proposed infrastructure state implementation plan (SIP) revision for the 2012 Fine Particulate Matter and the 2015 Ozone National Ambient Air Quality Standard (NAAQS).

The purpose of the proposed SIP revision is to bring the nonattainment area into compliance with federal requirements for infrastructure as required under CAA Title I, Part D for the 2012 Fine Particulate Matter and the 2015 Ozone NAAQS. ADEQ is requesting the U.S. Environmental Protection Agency (EPA) approve this SIP revision into the Arizona SIP.
