(a) Printing processes that use control equipment to comply with the provisions of this Part must test and monitor the control equipment to ensure the overall removal efficiency. Test methods included in this section must be used to demonstrate the overall removal efficiency.

1. (1) For control equipment that uses VOC/solvent recovery, overall removal efficiency must be demonstrated using methods described in paragraphs (b)(1) and (2) of this section.
2. (2) For control equipment other than VOC/solvent recovery, the chosen demonstration method must include provisions to determine the overall removal efficiency.

(b) The owner or operator of a printing process subject to this Part must follow notification requirements and test procedures in Subpart 202-1 of this Title.

1. (1) One of the following test methods from appendix A of 40 CFR 60 (see Table l, section 200.9 of this Title) must be used to measure the VOC concentration of a gas stream at the inlet and outlet of the control equipment:

   1. (i) method 18, Measurement of Gaseous Organic Compound Emissions by Gas Chromatography;
   2. (ii) method 25, Determination of Total Gaseous Non-Methane Organic Emissions as Carbon; or
   3. (iii) method 25A, Determination of Total Gaseous Organic Concentration Using a Flame Ionization Analyzer;
   4. (iv) methods not listed above must be approved in advance by the Department and the United States Environmental Protection Agency.
2. (2) Acceptable analytical methods for determining the VOC content, water content, density, volume of solids and weight of solids of surface coatings and printing inks are presented in appendix A, methods 24 and 24A (as appropriate), of 40 CFR 60 (see Table l, section 200.9 of this Title). Alternate analytical methods for surface coating and printing ink analysis must be approved by the department and the United States Environmental Protection Agency. Instead of analytical methods, the department may accept the manufacturer's certification of VOC content of ink coating or adhesives, if supported by actual batch records.

(c) Continuous control equipment monitors for the following parameters must be installed, periodically calibrated, and operated at all times that the associated control equipment is operated:

1. (1) combustion zone temperature of all oxidizers;
2. (2) inlet temperature at the catalytic oxidizer bed;
3. (3) break-through of VOC on a carbon adsorption unit; and
4. (4) any other continuous monitoring or recording device required by the department.
