STATUTORY AUTHORITY: KRS 224.10-100

NECESSITY, FUNCTION, AND CONFORMITY: KRS 224.10-110 requires the Environmental and Public Protection Cabinet to prescribe administrative regulations for the prevention, abatement and control of air pollution. 42 USC 7410 likewise requires the state to implement standards for national primary and secondary ambient air quality. This administrative regulation provides for the control of volatile organic compound emissions from existing miscellaneous metal parts and products surface coating operations.

 

Section 1. Definitions. As used in this administrative regulation, all terms not defined in this section shall have the meaning given to them in 401 KAR 61:001.

(1) "Affected facility" means a coating line located at job shops and original equipment manufacturing industries which apply coatings on metal substrates not subject to an administrative regulation, other than 401 KAR 61:060, in this chapter.

(2) "Applicator" means the mechanism or device used to apply the coating, including but not limited to dipping, spraying, or flow coating.

(3) "Flash-off area" means the space between the applicator and the oven.

(4) "Single coat" means only one (1) film of coating is applied to the metal substrate.

(5) "Prime coat" means the first of two (2) or more films of coating applied in an operation.

(6) "Topcoat" means the final film or series of films of coating applied in a two (2) coat (or more) operation.

(7) "Coating line" means a series of equipment or operations used to apply, dry, or cure any prime, topcoat or single coatings containing volatile organic compounds (VOCs). This shall include, but is not limited to:

(a) Mixing operations;

(b) Process storage;

(c) Applicators;

(d) Drying operations including, but not limited to, flash-off area evaporation, oven drying, baking, curing, and polymerization;

(f) Leaks, spills and disposal of VOCs;

(g) Processing and handling of recovered VOCs;

(h) For the purposes of determining compliance with this administrative regulation, if equipment or an operation is considered to be a part of more than one (1) coating line, its VOC emissions shall be assigned to each coating line of which it is a part proportionally to the throughput of VOC it receives from or distributes to each coating line;

(i) If a portion of the series of equipment or operations qualifies for an exemption according to Section 6 of this administrative regulation, then that portion shall be considered to be a separate coating line.

(8) "Process storage" means mixing tanks, holding tanks, and other tanks, drums, or other containers which contain surface coatings, VOCs, or recovered VOCs; but does not mean storage tanks of petroleum liquids which are subject to 401 KAR 59:050, 401 KAR 59:052, or 401 KAR 61:050.

(9) "Miscellaneous metal parts and products" means items including but not limited to:

(a) Large farm machinery (harvesting, fertilizing and planting machines, tractors, combines, etc.);

(b) Small farm machinery (lawn and garden tractors, lawn mowers, rototillers, etc.);

(c) Small appliances (fans, mixers, blenders, crock pots, dehumidifiers, vacuum cleaners, etc.);

(d) Commercial machinery (computers and auxiliary equipment, typewriters, calculators, vending machines, etc.);

(10) "Heat sensitive material" means materials which cannot be exposed to temperatures greater than eighty-two (82) to ninety-three (93) C (180-200F).

(11) "Air or forced air-dried items" means parts that are too large or too heavy for practical size ovens; parts that are sensitive to heat; parts to which heat sensitive materials are attached; or equipment assembled prior to top coating for specific performance or quality standards.

(12) "Outdoor or harsh exposure or extreme environmental conditions" means exposure to any of the following: year round weather conditions, temperatures consistently above ninety-five (95)C, detergents, scouring, solvents, corrosive atmospheres; and similar environmental conditions.

(13) "Classification date" means February 4, 1981.

(14) "VOCs net input" means the total amount of VOCs input to the affected facility minus the amount of VOCs that are not emitted into the atmosphere. VOCs that are prevented from being emitted to the atmosphere by the use of control devices shall not be subtracted from the total for the purposes of determining VOC net input. If the nature of an operation or a design of equipment is such as to permit more than one (1) interpretation of this definition, the interpretation that results in the minimum value for allowable emissions shall apply.

(15) "Glass adhesive primer" means a primer applied to the body of a vehicle to etch the topcoat for the purpose of ensuring a positive bond with the adhesive used to secure the windshield and back glass to the vehicle in a manner consistent with federal safety regulations.

 

Section 2. Applicability. (1) This administrative regulation shall apply to each affected facility commenced before the classification date defined in Section 1 of this administrative regulation which is located in a county or portion of a county which is designated ozone nonattainment, for any nonattainment classification except marginal, under 401 KAR 51:010.

(2) This administrative regulation shall not apply to affected facilities which are subject to local air pollution control district regulations which have been approved by the cabinet and the U.S. EPA.

 

Section 3. Standard for VOCS. No person shall cause, allow, or permit an affected facility to discharge into the atmosphere more than fifteen (15) percent by weight of the VOCs net input into the affected facility.

 

Section 4. Compliance. (1) In all cases the design of a control system is subject to approval by the cabinet.

(2) Compliance with the standard in Section 3 of this administrative regulation shall be demonstrated by a material balance unless the cabinet determines that a material balance is not possible. If a material balance is not possible, compliance shall be determined based upon an engineering analysis by the cabinet of: the control system design, control device efficiency, control system capture efficiency, and other factors that could influence the performance of the system. If requested by the cabinet, Method 25, which has been incorporated by reference in 401 KAR 50:015, shall be performed in order to determine the efficiency of the control device or demonstrate compliance with the standard. Capture efficiency shall be determined by procedures specified in 401 KAR 50:047.

(3) With the prior approval of the cabinet, the owner or operator may elect to effect all changes necessary to qualify for an exemption under Section 6 of this administrative regulation.

(4) If deemed necessary by the cabinet, the cabinet shall obtain samples of the coatings used at an affected facility to verify that the coatings meet the requirements in Section 6 of this administrative regulation. Appendix A to 40 CFR 60, Method 24, which has been incorporated by reference in 401 KAR 50:015, shall be used as applicable to determine compliance of the coatings unless the cabinet and the U.S. EPA determine that other methods would be more appropriate.

(5) Compliance on one (1) coating line with VOC emission limits shall be based on an averaging period not to exceed twenty-four (24) hours. If it is not economically or technically feasible to determine emissions on a daily basis, alternatives expressing emission limits for longer averaging times may be accepted if approved by the cabinet and the U.S. EPA as a SIP revision.

(6) The amount of exempt solvents shall be subtracted from the amount of coatings, just like water, with the ultimate value of interest being the mass of VOC per unit volume of coating less exempt solvent or water or both.

(7) Calculations to determine equivalency on one (1) coating line shall be based on mass of VOC per volume of solids.

(8) Daily records shall be maintained by the source for the most recent two (2) year period. These records shall be made available to the cabinet or the U.S. EPA upon request. The records shall include, but not be limited to, the following:

(a) Applicable administrative regulation number;

(b) Application method and substrate type;

(c) Amount and type of adhesive, coating (including catalyst and reducer for multicomponent coatings), or solvent used at each point of application, including exempt compounds;
