(1) Applicability.

(a) Emissions of particulate matter shall be limited through the application of Reasonably Available Control Technology (RACT) for any emissions unit, issued an air permit on or before May 30, 1988, that emits particulate matter and is located in:

1. That portion of Hillsborough County which falls within the area of the circle having a centerpoint at the intersection of US 41 South and State Road 60 and a radius of 12 kilometers;

2. The downtown Jacksonville area in Duval County located within the following boundary lines: south and then west along the St. Johns River from its confluence with Long Branch Creek, to Main Street; north along Main Street to Eighth Street; east along Eighth Street to Evergreen Avenue; north along Evergreen Avenue to Long Branch Creek; and east along Long Branch Creek to the St. Johns River; or

(2) Exemptions. The following facilities and emissions units are exempt from the provisions of this rule:

(a) Any facility with total maximum allowable emissions of particulate matter of less than 15 tons per year and 5 pounds per hour.

(b) Any facility whose owner or operator demonstrates to the Department that the impact within an area as described in subparagraph 62-296.700(1)(a)1. or 2., F.A.C., above, that the total maximum allowable particulate matter emissions from such facility will not exceed 1 ug/m3, annual average, and 5 ug/m3, 24-hour average.

(c) Any emissions unit which has total allowable emissions of particulate matter of less than one ton per year.

(d) Any emissions unit of unconfined particulate matter which is located more than five kilometers outside the boundary of an area as described in subparagraph 62-296.700(1)(a)1. or 2., F.A.C., above.

(e) Any emissions unit of unconfined particulate matter from open stockpiling of materials, vehicular traffic and other emissions from roads and plant grounds, or construction activities.

(f) Any moveable drop transfer point where the discharge point and receiving point of the materials being handled must be moved in relationship to each other, either continuously or intermittently, such that enclosure of the drop transfer point with a device to control emissions of particulate matter is not practicable.

(g) Any emissions unit which has received a determination of Best Available Control Technology pursuant to rule 17-2.630 (repealed) or 62-296.330 (repealed), F.A.C., or received a permit in connection with rule 17-2.500 (transferred), 17-2.510 (transferred), 62-212.400 (Prevention of Significant Deterioration) or 62-212.500 (Preconstruction Review of Nonattainment Areas), F.A.C.

(3) Specific RACT Emission Limiting Standards for Stationary Emissions Units. The specific particulate matter emission limiting standards set forth in rules 62-296.401 through 62-296.414, F.A.C., have been found to represent the application of RACT for each emissions unit category listed in those rules, except for those emissions unit categories listed in rules 62-296.701 through 62-296.712, F.A.C. For those emissions unit categories the particulate matter emission standards in rules 62-296.701 through 62-296.712, F.A.C., have been found to represent the application of RACT.

(4) Maximum Allowable Emission Rates.

(a) Emissions Unit Data. The new or revised operating permit for each emissions unit subject to the provisions of this rule shall specify:

1. The maximum heat input rate, charging rate, production rate, through-put rate, and/or materials handling rate, as appropriate. The maximum heat input rate, charging rate, production rate, through-put rate, or materials handling rate shall be the maximum rate at which the emissions unit is capable of being operated on a continuous basis.

2. The maximum dry standard volumetric flow rate for each emission point, when applicable:

The maximum dry standard volumetric flow rate for each emissions unit or component emissions unit operation shall be the minimum dry standard volumetric flow rate that is necessary to safely and properly vent or operate the emissions unit when it is operated at its maximum continuous operating rate.

3. The control device through which each gas stream is vented and the emission point from which each gas stream is discharged to the open air,

4. The height above ground, exit diameter, UTM coordinates, and nature of each emission point through which particulate is or may be vented,

5. The exit gas temperature, actual volumetric flow rate and moisture content of each particulate bearing gas stream that is or may be vented to the open air,

6. Pertinent operating or control equipment parameters, such as pH of scrubber solution, pressure drop in scrubber, pressure on spray nozzle, etc., when such information is needed to confirm the control device is operating normally,

7. The permitted operating schedule (hrs./day, days/wk., wk./yr.).

(b) Maximum Emission Rates. The new or revised operating permit for each emissions unit shall specify the maximum allowable emission rate for each emissions unit or group of commonly vented emissions units sources in accordance with the following provisions:

1. The maximum allowable emission rate expressed in lbs/hr, lbs/day and tons/yr (or other equivalent units) shall be determined for each emissions unit (for example, each drop transfer point, screening operation, kiln, or dryer) by applying the appropriate emission limitation contained in rules 62-296.401 through 62-296.414, F.A.C., or rules 62-296.701 through 62-296.712, F.A.C., to the maximum applicable emissions unit operation rate or dry standard volumetric flow rate and the permitted operating schedule as specified in the operating permit pursuant to the provisions of paragraph 62-296.700(4)(a), F.A.C.

2. If several emissions units are vented through a common control device or emission point, the maximum allowable emission rate for the common emission point shall be the sum of the individual maximum allowable emission rates for each emissions unit vented by the emission point.

3. The owner or operator of an emissions unit or a group of emissions units that is subject to an emission limitation set forth in rules 62-296.701 through 62-296.712, F.A.C., and that is vented through more than one emission point, shall, subject to the approval of the Department, prorate the total allowable emission for such emissions unit among all emission points that vent the affected emissions unit such that a specific maximum allowable emission rate is assigned to each emission point. The operating permits for emissions units shall be revised in accordance with subsection 62-296.700(4), F.A.C., to reflect the maximum allowable emission rates for each emission point.

4. The operating permit shall specify whether compliance shall be determined by measuring the emissions vented from each individual emissions unit or by measuring the emissions from the common emission point. In determining whether compliance shall be determined for each emissions unit individually or for a group of commonly vented emissions units at the common emission point, the department shall consider the following factors:

a. If all emissions units that are vented through a common emission point are subject to the same type of emission limiting standard (i.e., grains per dry standard cubic foot (gr/dscf)) and are all part of the same system of unit operations such that when one emissions unit is in operation the other emissions units will also normally be in operation, the Department may specify that compliance be determined at the common point of emission.

b. If the various emissions units that are vented through a common emission point are parts of different operating systems or are subject to different types of emission limiting standards (i.e., gr/dscf, lbs/ton of feed, lbs/MMBTU, percent opacity, etc.). The Department may specify that compliance with the various emission standards be determined separately for each emissions unit operation.

(5) Circumvention. No owner or operator of an emissions unit subject to the requirements of rules 62-296.401 through 62-296.414 or rules 62-296.701 through 62-296.712, F.A.C., establishing maximum concentrations of emissions of particulate matter in the exhaust gas from the emissions unit shall circumvent the provisions of an applicable emission limitation by increasing the volume of gas in any exhaust or group of exhausts for the purpose of reducing the stack gas concentration. This includes allowing dilution air to enter the system through leaks, open vents, or similar means.

(6) Operation and Maintenance Plan. The new or revised operating permit for each emissions unit subject to the provisions of this rule shall specify an operation and maintenance plan for the particulate control devices, the collection systems and the processing systems.

(a) Air Pollution Control Devices and Collection Systems. The plan shall include a schedule for the maintenance and inspection of each control device and collection system and a schedule for recording performance parameters of the control devices, collection systems and auxiliary equipment. Records of inspections, maintenance and performance data of control devices and auxiliary equipment shall be retained by the emissions unit for a minimum of two years and shall be made available to the Department upon request.
