Maricopa County Air Quality Department (MCAQD) is proposing changes to the following Rules:

  • Rule 321 affecting Municipal Waste Landfills. MCAQD is proposing to change the applicability date from May 30, 1991 to July 17, 2014 and revising Section 300 of the rule.
  • Rules 322, 323, and 324 affecting power plants, fuel burning equipment and stationary reciprocating engines. MCAQD is revising the rules to address EPA comments on the SIP.
  • Rule 204, Emission Reduction Credits for Use with the Arizona Emissions Bank. MCAQD is following ADEQ to add nontraditional sources of emission reduction credits to the current rule. This change will expand the emission bank program which should benefit sources who reduce their emissions and major sources considering locating to nonattainment areas.
