77. SET A PUBLIC HEARING ON AIR QUALITY RULE DEFINITION REVISIONS Pursuant to A.R.S. §49-479(b), set a public hearing for September 25, 2013 to solicit comments and consider the adoption of proposed amendments to Maricopa County Air Pollution Control Regulations, Rules 100 (General Provisions and Definitions); Rule 330 (Volatile Organic Compounds); Rule 33l (Solvent Cleaning); Rule 333 (Petroleum Solvent Dry Cleaning); Rule 334 (Rubber Sports Ball Manufacturing); Rule 335 (Architectural Coatings); Rule 336 (Surface Coating Operations); Rule 338 (Semiconductor Manufacturing); Rule 339 (Vegetable Oil Extraction Processes); Rule 340 (Cutback and Emulsified Asphalt); Rule 341 (Metal Investment Casting); Rule 342 (Coating Wood Furniture and Fixtures); Rule 343 (Commercial Bread Bakeries); Rule 344 (Automotive Windshield Washer Fluid); Rule 345 (Vehicle and Mobile Equipment Coating); Rule 346 (Coating Wood Millwork); Rule 347 (Ferrous Sand Casting); Rule 348 (Aerospace Manufacturing and Rework Operations); Rule 349 (Pharmaceutical, Cosmetic, and Vitamin Manufacturing Operations); Rule 352 (Gasoline Delivery Vessel Testing and Use); Rule 353 (Gasoline in Stationary Dispensing Tanks); Rule 358 (Polystyrene Foam Operations); and Appendix G (Incorporated Materials) . Upon Board approval, this item will become effective September 25, 2013. The definition of “non-precursor organic compound” and the definition of “volatile organic compound (VOC)” are proposed to be revised in 22 rules in the Maricopa County Air Pollution Control Regulations in order to incorporate the most current U.S. Environmental Protection Agency (EPA) definitions of each. The department is further proposing to list the EPA-recognized non-precursor organic compounds in Appendix G (Incorporated Materials). Non-precursor organic compounds are compounds that the EPA has determined make a negligible contribution to the formation of ground-level ozone. A consistent and current list of non-precursor organic compounds will benefit the department, sources and citizens of Maricopa County. It is to the department’s advantage to regularly update this list to provide sources alternatives to ozone creating VOCs as well as provide consistent application of the non-precursor organic compounds to all sources. It is to the source’s advantage to utilize the non-precursor organic compounds to reduce VOC emissions and the associated recordkeeping requirements. Citizens will benefit due to the reduction of ozone in our air. Although this rulemaking affects many rules and essentially any source that uses non-precursor organic compounds and VOCs, the rulemaking has been non-controversial. (C-85-14-003-7-00)
