(d) When an owner and/or operator of a coating line utilizes control equipment to comply with the provisions of this Part, test methods acceptable to the department must be used to determine the overall removal efficiency during a required performance test.

1. (1) The overall removal efficiency may be made by directly measuring VOC/solvent recovery and VOC/solvent usage rates where VOC/solvent recovery is the only control equipment. Methods provided for in subdivision (a) or (b) of this section must be used.

2. (2) For any control equipment other than VOC/solvent recovery, this determination must include provisions to determine both the efficiency of the capture system and the control equipment. The approved VOC CE test methods are contained in the following table. Test methods 204 through 204F (M204 - M204F) are included in appendix M of 40 CFR part 51 (see table 1, section 200.9 of this Title). The approved test methods for determining the efficiency of the control equipment are listed in subdivision (e) of this section.

   Approved VOC CE Test Methods
   Protocol	Enclosure Verification	Liquid Input (L)	Captured Emissions (G)	Fugitive Emissions (F) or (FB)	CE formula
   Permanent Total Enclosure	M204	NA	NA	NA	Assume 100%
   Temporary Total Enclosure (gas/gas mass balance test)	M204	NA	M204B or M204C	M204D	G/(G+F)
   Temporary Total Enclosure (liquid/gas mass balance test)	M204	M204A or M204F	NA	M204D	(L-F)/L
   Building Enclosure (gas/gas mass balance test)	M204	NA	M204B or M204C	M204D	G/(G+F)
   Building Enclosure (liquid/gas mass balance test)	M204	M204A or M204F	NA	M204D	(L-F)/L

3. (3) Alternative CE protocols and test methods may be allowed if the data quality objective approach or lower confidence limit approach requirements are met in conjunction with the additional criteria set forth in the EPA guidance document entitled ‘Guidelines for Determining Capture Efficiency’ (see table 1, section 200.9 of this Title). The alternative CE protocols and test methods must be approved in advance by the department. Also, the multiple line testing procedures outlined in the above guidance document can be used to determine CE if the applicable criteria are satisfied. The multiple line testing CE protocols and test methods must be approved in advance by the department.

(e) The owner and/or operator of a surface coating line must follow the applicable notification requirements, protocol requirements, and test procedures of Part 202 of this Title for testing and monitoring. Depending upon conditions at a test site, one of the following test methods from appendix A of 40 CFR part 60 (see table 1, section 200.9 of this Title) must be used when measuring VOC contents of a gas stream at the inlet and outlet of a control device to determine the destruction and/or removal efficiency:

1. (1) method 18, Measurement of Gaseous Organic Compound Emissions by Gas Chromatography;
2. (2) method 25, Determination of Total Gaseous Organic Emissions as Carbon; or
3. (3) method 25A, Determination of Total Gaseous Organic Concentration Using a Flame Ionization Analyzer.

(f) If an air cleaning device is used, continuous monitors for the following parameters must be installed, periodically calibrated, and operated when the associated control equipment is operating:

1. (1) exhaust gas temperature of all incinerators;
2. (2) temperature rise across catalytic incinerator bed;
3. (3) breakthrough of VOCs on a carbon adsorption unit; and
4. (4) any other continuous monitoring or recording device required by the department.

(h) Any information or record showing noncompliance with the requirements of this Part must be reported to the department within 30 days following notice or generation of the information or record.

1. (1) All records required by this section must be maintained at the facility for a period of five years.
