Air Quality Department, Bob Huhn, PIO
The Maricopa County Air Quality Department (department) is proposing to revise the rules listed below. The public comment period for these rules is anticipated to begin November 29, 2013 and to close December 30, 2013. AQ-2013-004-Incorporation by Reference Rule 321: Municipal Solid Waste Landfills Rule 360: New Source Performance Standards Rule 370: Federal Hazardous Air Pollutant Program Rule 371: Acid Rain Appendix G: Incorporated Materials The department is proposing to incorporate by reference various federal regulations and documents promulgated by the U.S. Environmental Protection Agency (EPA) and published in the Federal Register as of July 1, 2013, including actions related to New Source Performance Standards (NSPS), National Emission Standards for Hazardous Air Pollutants (NESHAP), Acid Rain and other parts of Title 40 of the Code of Federal Regulations (CFR). This incorporation by reference is necessary before the department requests the EPA’s delegation of authority to enforce the federal rules documented in the Maricopa County Air Pollution Control Regulations Rules 321, 360, 370, 371, and Appendix G. The department is also proposing to delete two subparts from Rule 370: 40 CFR 60, Subpart FFFF—Emission Guidelines and Compliance Times for Other Solid Waste Incinerator Units that Commenced Construction on or before December 9, 2004; and 40 CFR 60, Subpart MMMM—Emission Guidelines and Compliance Times for Existing Sewage Sludge Incineration Units. On August 1, 2013, the EPA declined the department’s request for delegation of authority for these two subparts, citing the Clean Air Act, Section 111(c).The EPA does not delegate regulatory authority for emission guidelines.
