EKAPCD 410.8-15 3/13/20145. In no case shall compliance through the use of a VOC emission control system

result in VOC emissions in excess of th e VOC emissions which would result from compliance with applicable provisions of Sections V.A., V.B., V.C., or V.E.

6. The minimum required overall capture and c ontrol efficiency of an emission control system at which an equivalent or greater level of VOC reduction will be achieved shall be calculated by using the following equation:

VOC LWc 1-(VOC LWn,Max / D n,Max ) CE = x 100 1- VOC LWn,Max x 1- (VOC LWc / D c )

Where:

CE = Minimum Required Overall Capture and Control Efficiency, percent

VOC LWc = VOC Limit, less water and exempt compounds

VOC LWn,Max = Maximum VOC content of noncompliant coating used in conjunction with a cont rol device, less water and exempt compounds

D n,Max = Density of solvent, reducer, or thinner contained in the noncompliant coating, containing the maximum VOC content of the multi-component coating

D c = Density of corresponding so lvent, reducer, or thinner used in the compliant coating system.

G. Prohibition of Solicitation : No person shall solicit, speci fy, or require an operator to use any coating, solvent, spray equipment, or VOC emission control system that does not meet the limits or requirements of this rule.

H. Sell-Through/Existing Stock of Coatings : A coating manufactured prior to amendment date of this rule, that complied with the VOC Content limit(s) in effect at that time, may be sold, supplied, or offered for sale for 12 months after rule adoption date. Such a coating may be applied at any time, both before and after adoption date, provided

manufacture Date-Code and VOC Content is clearly printe d on coating container.

I. Specialized Milita ry Coating Operations VOC Requirements: APCO may approve alternative VOC or vapor pressure limits fo r coatings, adhesives or solvents that are specified in specialized military Technical Orders, for which no viable substitutions are available. The owner/operator must subm it a written request to the APCO, and present documentation and sufficient justification regarding the operation and materials.

EKAPCD 410.8-16 3/13/2014VI. Administrative Requirements

A. Recordkeeping

1. An operator subject to the requirement s of this rule shall have coating manufacturer's specifications, either listed on the coati ng container, product data sheet, or on Safety Data Sheet (SDS), avai lable for review and shall maintain daily records which show the following information as applicable:

a. Manufacturer name and type for each coating, solvent, thinner, reducer or stripper used;

b. Mix ratio by volume of components adde d to the original material prior to application;

c. Grams of VOC per liter of each coating, solvent, thinner, reducer, or stripper less water and exempt compounds, as applied;

d. Volume and method of application of each coating, solvent, thinner, reducer, or stripper applied; and

e. Vapor pressure of solvents used.

2. An operator shall maintain records to support that the following coatings have been specified for their intended application:

a. Adhesion promoter; b. Antichafe coating; c. Electric/radiation effect; d. Fuel tank adhesive; e. High temperature coating; f. Impact resistant coating; g. Optical anti-reflective coating; h. Rain erosion resistant wing coating.

3. An operator using a VOC emission control system pursuant to Section V.F. as a means of complying with this Rule, sha ll maintain daily records of key system operating parameters and maintenance procedures, which will demonstrate continuous operation and compliance of th e VOC emission control system during periods of emission-producing activities. Key system operating parameters are those necessary to ensure compliance with VOC limits. The parameters may include, but are not limited to, temperat ures, pressures, and flow rates.

4. Records required by this Rule shall be re tained for a minimum of five (5) years and made available on site during normal busin ess hours to the AP CO, ARB, or EPA
upon request.

EKAPCD 410.8-17 3/13/2014EKAPCD 410.8-18 3/13/2014 B. Test Methods

1. Coating and solvent VOC content shall be determined using EPA Method 24 or its

constituent methods. The VOC content of co atings containing exempt halogenated VOCs shall be determined by usi ng ARB Method 432, “Determination of Dichloromethane and 1,1,1- Trichloroethan e in Paints and Coatings” (September 12, 1998). or SCAQMD Method 303 (Deter mination of Exempt Compounds).

2. The solid content of pretreatment coati ngs shall be determined using EPA Method 24. The acid content of pretreatment coa tings shall be determined using ASTM Method D1613 06 (Standard Test for Acidity of Volatile Solvents and Chemical Intermediates used in Paint, Varnish, Lacquer and Related Products).

3. The test method for determining the fire re sistance of an interi or coating shall be Federal Aviation Administration-required Ohio State University Heat Release, Fire

and Burn Tests.

4. The VOC composite vapor pressure of a blended solvent shall be determined by quantifying the amount of each organi c compound in the blend using gas chromatographic analysis SCAQMD Te st Method 308-91 “Quantitation of Compounds by Gas Chromatography” (Febru ary 1993) and by calculating the VOC composite vapor pressure of the solvent by summing the product of the vapor pressure of each pure component and its molar fraction. For the purpose of this calculation, the blend shall be assumed to be an ideal solution where Raoult's Law applies. The vapor pressure of each pure component shall be obtained from published reference manuals or handbooks.

5. VOC emissions from enclosed systems used to clean coating application equipment shall be determined by the manufacturer using the SCAQMD General Test Method for Determining Solvent Losses fr om Spray Gun Cleaning Systems.

6. The control efficiency of a VOC emission control system’s control device(s) shall be determined using EPA Methods 2, 2A, 2C , or 2D for measuring flow rates and EPA Methods 25, 25A, or 25B for measuring the total gaseous organic

concentrations at the inlet and outlet of the control device. EPA Method 18 or ARB Method 422, “Determination of Volatile Organic Compounds in Emissions from Stationary Sources” (September 12, 1990) shal l be used to determine the emissions of exempt compounds.

7. The capture efficiency of a VOC emissi on control system’s collection device(s) shall be determined according to EPA’s “Guidelines for Determining Capture Efficiency,” January 9, 1995 and 40 CF R 51, Appendix M, Methods 204-204F, as applicable, or any other method approved by EPA, ARB, or APCO.

8. When more than one test method or se t of test methods are specified for any emissions testing, a violation of any test established in S ection VI.B. shall constitute

a violation of the Rule.
