Rule 62-296.700, F.A.C., requires certain existing emissions units located in a particulate matter (PM) air quality maintenance area or in the area of influence of such an air quality maintenance area to meet specified PM emission limits. Rule 62-204.340, F.A.C., provides that portions of Duval and Hillsborough counties are PM air quality maintenance areas. Rules 62-296.701 through 62-296.712, F.A.C, provide the source category-specific PM emission limits that facilities located in these PM maintenance areas must meet. Rules 62-296.701, 62-296.703, 62-296.706, 62-296.709, and 62-296.710, F.A.C., provide PM emission limits for five source categories: Rule 62-296.701, F.A.C., provides PM emission limitations for Portland Cement plants; Rule 62-296.703, F.A.C., provides PM emission limitations for carbonaceous fuel burning equipment; Rule 62-296.706, F.A.C., provides PM emission limitations for glass melting furnaces; Rule 62-296.709, F.A.C., provides PM emission limitations for lime kilns; and Rule 62-296.710, F.A.C., provides PM emission limitations for smelt dissolving tanks. These five rules are being repealed because the facilities that were subject to these rules no longer exist. Rules 62-296.701, 62-296.703, 62-296.706, 62-296.709, and 62-296.710, F.A.C., are cross-referenced in Rules 62-296.700 and 62-296.712, F.A.C., but the repeals will not impact Rules 62-296.700 and 62-296.712, F.A.C., as the facilities subject to those cross-references no longer exist.
