(1) Applicability.
(a) The emission limiting standards and control technology set forth in Fl. Admin. Code R. 62-296.511, shall apply to cold cleaning, open-top vapor degreasing, and conveyorized degreasing operations. All degreasing facilities using the following halogenated solvents are subject to the requirements (including compliance deadlines) of the national emission standard for halogenated solvent degreasers at 40 C.F.R. part 63, Subpart T, adopted and incorporated by reference in Fl. Admin. Code R. 62-204.800: carbon tetrachloride, chloroform, tetrachloroethylene, 1,1,1-trichloroethane, trichloroethylene, and methylene chloride. Until compliance is achieved with the requirements of 40 C.F.R. part 63, Subpart T, existing (as of November 29, 1993) halogenated solvent degreasing facilities must also comply with the requirements of this rule. The requirements of this rule shall not apply to any halogenated solvent degreasing facility after it has achieved compliance with the requirements of 40 C.F.R. part 63, Subpart T.
(b) The provisions of Fl. Admin. Code R. 62-296.511, shall apply with the following exceptions:
1. Open-top vapor degreasers with an open area smaller than 10.8 square feet (one square meter) shall be exempt from Fl. Admin. Code R. 62-296.511(3)(c),
2. Conveyorized degreasers with an air/vapor interface smaller than 21.5 square feet (2.0 square meters) shall be exempt from Fl. Admin. Code R. 62-296.511(4)(b)
(2) Cold Cleaning Control Technology. Except as provided under subsection 62-296.511(1), F.A.C., the owner or operator of a cold cleaning facility shall comply with each of the following requirements:
(a) Equip the cleaner with a cover. The cover shall be so designed that it can be easily operated with one hand if:

2. The solvent is agitated,
3. The solvent is heated.
(b) Equip the cleaner with a facility for draining cleaned parts. The drainage facility shall be constructed internally so that parts are enclosed under the cover while draining if the solvent volatility is greater than 0.6 pounds per square inch (31 millimeters of mercury or 4.1 kilopascals) measured at 100 degrees Fahrenheit (38 degrees Celsius), except that the drainage facility may be external for the applications where an internal type cannot fit into the cleaning system.
(c) Install one of the following control devices if the solvent volatility is greater than 0.6 pounds per square inch (31 millimeters of mercury or 4.1 kilopascals) measured at 100 degrees Fahrenheit (38 degrees Celsius), or if the solvent is heated above 120 degrees Fahrenheit (50 degrees Celsius):
1. Freeboard that gives a freeboard ratio greater than or equal to 0.7, or
2. Water cover (solvent must be insoluble in and heavier than water), or
3. Other systems of equivalent control such as refrigerated chiller or carbon absorption.
(d) Provided a permanent, conspicuous label summarizing the operating requirements.
(e) Store waste solvent only in covered containers and not dispose of waste solvent or transfer it to another party, such that greater than 20 percent of the waste solvent (by weight) can evaporate into the atmosphere.
(f) Close the cover whenever parts are not being handled in the cleaner.
(g) Drain the cleaned parts for at least 15 seconds or until dripping ceases.
(h) If used, supply a solvent spray that is a solid fluid stream (not a fine, atomized, or shower-type spray) at a pressure which does not cause excessive splashing.
(3) Open Top Vapor Degreaser Control Technology. Except as provided under Fl. Admin. Code R. 62-296.511, the owner or operator of an open top vapor degreaser shall comply with each of the following requirements:
(a) Equip the vapor degreaser with a cover that can be opened and closed easily without disturbing the vapor zone.
(b) Provide the following safety switches:
1. A condenser flow switch and thermostat which shut off the heat if the condenser coolant is either not circulating or too warm; and,
2. A spray safety switch which shuts off the spray pump if the vapor level drops more than 4 inches (10 centimeters) below the bottom condenser coil; and,
3. A vapor level control thermostat which shuts off the heat when the vapor level rises too high.
(c) Install one of the following control devices:
1. A freeboard ratio greater than or equal to 0.75, and a powered or mechanically assisted cover if the degreaser opening is greater than 10.8 square feet (1.0 square meter), or
2. Refrigerated chiller, or
3. An enclosed design (cover or door opens only when the dry part is actually entering or exiting the degreaser), or
4. A carbon adsorption system, with ventilation greater than or equal to 50 cubic feet per minute per square foot (15 cubic meters per minute per square meter) of air/vapor area (when cover is open), and exhausting less than 25 parts per million of solvent averaged over one complete adsorption cycle.
(d) Keep the cover closed at all times except when processing work loads through the degreaser.
(e) Minimize solvent carryout by:
1. Racking parts to allow complete drainage; and,
2. Moving parts in and out of the degreaser at less than 11 feet per minute (3.3 meters per minute); and,
3. Holding the parts in the vapor zone at least 30 seconds or until condensation ceases; and,
4. Decanting any pools of solvent on the cleaned parts before removal from the vapor zone; and,
5. Allowing parts to dry within the degreaser for at least 15 seconds or until visually dry.
(f) Not degrease porous or absorbent materials, such as cloth, leather, wood, or rope.
(g) Not occupy more than half of the degreaser’s open-top area with a workload.
(h) Not load the degreaser to the point where the vapor level would drop more than 4 inches (10 centimeters) below the bottom condenser coil when the workload is removed from the vapor zone.
(i) Always spray below the vapor level.
(j) Repair solvent leaks immediately, or shut down the degreaser.
(k) Store waste solvent only in covered containers and not dispose of waste solvent or transfer it to another party, such that greater than 20 percent of the waste solvent (by weight) can evaporate into the atmosphere.
(l) Not operate the cleaner so as to allow water to be visually detectable in solvent exiting the water separator.
(m) Not use ventilation fans near the degreaser opening, nor provide exhaust ventilation exceeding 66 cubic feet per minute per square foot (20 cubic meters per minute per square meter) of degreaser open area, unless necessary to meet OSHA requirements.
