PURPOSE: This regulation restricts volatile organic compound emissions from industrial surface coating operations.

Editor’s Note: The secretary of state has determined that the publication of this rule in its entirety would be unduly cumbersome or expensive. The entire text of the material referenced has been filed with the secretary of state. This material may be found at the Office of the Secretary of State or at the headquarters of the agency and is available to any interested person at a cost established by state law.

1. (1) Application.

   1. (A) This regulation shall apply only in Clay, Jackson and Platte Counties.
   2. (B) This regulation shall apply to any installation with an uncontrolled potential to emit greater than 6.8 kilograms per day (kg/day) or 2.7 tons per year of volatile organic compounds (VOC) from industrial surface coating operations covered under this rule. This includes any installation which does not have an allowable VOC emission limit established under 10 CSR 10-6.060 or legally enforceable state implementation plan revision and has uncontrolled potential emissions greater than or equal to 6.8 kg/day or 2.7 tons per year. The uncontrolled potential emit is the potential emissions (as defined) plus the VOC removed by emission control devices.

   3. (C) This regulation is not applicable to the surface coating of the following metal parts and products:

      1. 1. Exterior refinishing of airplanes;
      2. 2. Automobile refinishing;
      3. 3. Customizing top coating of automo-

biles and trucks, if production is less than thirty-five (35) vehicles per day; and

1. 4. Exterior of marine vessels.

1. (2) Definitions of certain terms specified in this regulation may be found in 10 CSR 10- 6.020.
2. (3) General Provisions. No person shall emit to the atmosphere any VOC from any surface coating operation in excess of the amount allowed in section (4). This section will apply across all application areas, flash-off areas and ovens used in an affected coating operation.

1. (5) Determination of Compliance. Compliance with section (4) of this regulation shall be determined by the methods in subsections (5)(A)–(C) as applicable and appropriate.

   1. (A) For subsection (4)(A), the calculation of daily volume-weighted emission performance for automobile and light-duty truck primer-surfacer and topcoat operations, shall be made according to procedures detailed in the Environmental Protection Agency (EPA) document entitled Protocol for Determining the Daily Volatile Organic Compound Emission Rate for Automobile and Light Duty Truck Topcoat Operations dated June 10, 1988.

   2. (B) For subsection (4)(B)—

      1. 1. Compliance with emission limits may

be demonstrated using the method referenced in 10 CSR 10-6.030(14)(C) using the one (1)- hour bake. Emission performance shall be on the basis of a daily volume-weighted average of all coatings used in each surface coating operation as delivered to the coating applicator(s) on a coating line. The daily volumeweighted average (DAVGvw) is calculated by the following formula:

i=l (cid:1)(cid:3)(Ai × Bi) n

DAVGVW= ________________ C

Where: A=daily gal. each coating used (minus water and exempt solvents) in a surface coating operation.

B=lbs. VOC/gal coating (minus water and exempt solvents).

C=total daily gal. coating used (minus water and exempt solvents) in a surface coating operation.

n=number of all coating used in a surface coating operation;

or

1. 2. Compliance with the emission limits

in subsection (4)(B) may be demonstrated on pounds of VOC per gallon of coating solids basis. The demonstration is made by first converting the emission limit in subsection (4)(B) to pounds of VOC per gallon of coating solids as shown in the following three (3) steps: Specific to the Kansas City Metropolitan Area

lbs. VOC per gallon of coating minus water & exempt solvents 1) 7.36 lbs. per gallon

2) 1—Volume fraction of VOC

lbs. VOC per gallon of coating minus water & exempt solvents 3)

This value is the new compliance figure. The VOC per gallon of coating solids for each coating used is then determined using the method referenced 6.030(14)(C) using the one (1)-hour bake. The composite daily volume-weighted average of pounds of VOC per gallon of coating solids as tested for in the actual coatings used is compared to the new compliance figure. Source operations on a coating line using coatings with a composite actual daily volume-weighted average value less than or equal to the new compliance figure are in compliance with this regulation.

1. (C) As an alternative to the methods specified in subsections (5)(A) and (B), compliance with the emission limits specified in subsections (4)(A) and (B) may be demonstrated by the implementation of an emission reduction equivalency compliance plan which utilizes a daily weighted average of emissions from a single or combination of source operations provided that—

   1. 1. All source operations involved in the

plan are subject to the emission limits of this regulation;

1. 2. All source operations are part of the

same installation;

1. 3. The total actual VOC emissions for

each twenty-four (24)-hour period do not exceed the sum of the allowable emissions determined from section (4) for each source operation for the same period;

1. 4. Equivalent emission reductions are

accomplished in the time intervals allowed in subsection (4)(B) as would be required for individual source operations;

1. 5. After December 24, 1987, testing of

raw materials, emissions, equipment, or a combination of these, must be performed prior to initiation of an alternate compliance plan to verify any equivalent emission reductions claimed. All test methods and procedures to be acceptable for use in the equivalency determination must receive prior review and must have been approved by the director. Failure to gain test method and pro- (Emission Limit from (4)(B)) volume = fraction (average density of of VOC solvents used to originally establish the emission limit) Volume fraction = of solids

(Emission Limit from (4)(B)) lbs. VOC = Volume fraction gallon of of solids coating solids

in 10 CSR 10-

cedure approval of the director will invalidate the equivalency claim; and

1. 6. The overall plan is approved by the

director.

1. (6) Recordkeeping.

   1. (A) The owner or operator of a coating line shall keep records detailing specific VOC sources, as necessary to determine compliance. These may include:

      1. 1. The type and the quantity of coatings

used daily;

1. 2. The coating manufacturer’s formula-

tion data for each coating on forms provided or approved by the director;

1. 3. The type and quantity of solvents for

coating, thinning, purging and equipment cleaning used daily;

1. 4. All test results to determine capture

and control efficiencies, transfer efficiencies and coating makeup;

1. 5. The type and quantity of waste sol-

vents reclaimed or discarded daily;

1. 6. The quantity of pieces or materials

coated daily; and

1. 7. Any additional information pertinent

to determine compliance.

1. (B) Records, such as daily production rates, may be substituted for actual daily coating use measurement provided the owner submits a demonstration approvable by the director that these records are adequate for the purposes of this regulation. This will apply for all surface coating industries until the EPA issues national daily emissions recordkeeping protocols for specific industrial classifications.
2. (C) Records required under subsections (6)(A) and (B) shall be retained by the owner or operator for a minimum of two (2) years. These records shall be made available to the director upon request.
