Affected: IC 13-17

Sec. 5. (a) Sources subject to the requirements of this rule and the requirements of 326 IAC 20-26 shall comply with the requirements of 40 CFR 63.784* and 40 CFR 63.785*, as incorporated by reference in 326 IAC 20-26, in lieu of this section.

(b) Compliance requirements applicable to surface coating operations at a source subject to this rule are as follows:

1. (1) Compliance with the VOC emissions limiting requirements of section 4(a) of this rule shall be achieved on as applied basis for each operating day for the following products:

   1. (A) Coatings.
   2. (B) Cleaning materials.
2. (2) Compliance with the work practice standards of section 4(b) of this rule shall be achieved each operating day.

3. (3) Compliance with the VOC emissions limiting requirements of section 4(a) of this rule shall be demonstrated using 40 CFR 60, Appendix A, Method 24*. However, in lieu of testing each container of coating for VOC content, the alternative procedures that follow may be used:

   1. (A) If a coating as supplied by the manufacturer is applied to the substrate, in lieu of testing each container of coating using 40 CFR 60, Appendix A, Method 24*, a source subject to this rule may use the following alternative compliance procedure:

      1. (i) Use a certificate issued by the manufacturer certifying the VOC content for each batch of coating.
      2. (ii) Notify the coating applicators that they shall not add any thinner to the coatings.
      3. (iii) Specify the procedure to be used to notify the coating applicators in the compliance plan required to be submitted in section 7(b)(1) of this rule.

   2. (B) From May 1 through September 30, thinner may not be added to any general use coating. If a thinner is added to a coating before its application to the substrate, in lieu of testing the coating as applied using 40 CFR 60, Appendix A, Method 24*, a source subject to this rule may use the following alternative compliance procedure:

      1. (i) Use a certification from the coating manufacturer for each batch of that coating certifying its VOC content as supplied.
      2. (ii) Record the volume of coating used.
      3. (iii) Record the volume of thinner used.
      4. (iv) Record the VOC content of thinner used.
      5. (v) Type of coating.

4. (4) In the compliance plan required to be submitted to the department by section 7(b)(1) of this rule, the source shall specify the compliance procedure or procedures allowed under subdivision (3) that it intends to use to demonstrate compliance with the VOC emissions limiting requirements of section 4(a) of this rule. If the source desires to use a compliance procedure other than one (1) of the three (3) described in subdivision (3), the source shall include in its compliance plan an application for approval by the department and the U.S. EPA of the proposed compliance procedure, subject to the following conditions:

   1. (A) The application shall include a demonstration that there is a definite and consistent relationship between 40 CFR 60, Appendix A, Method 24* results and the alternative procedure results.
   2. (B) The source shall ensure that the coatings it uses are supplied by coating manufacturers that use the procedures in "Procedures for Certifying Quantity of Volatile Organic Compounds Emitted by Paints, Ink, and Other Coatings" (revised June 1986), U.S. EPA 450/3-84-019** to certify the VOC content of coatings and thinners.
   3. (C) The source may use the alternative procedure during the time the application is being reviewed by the department and the U.S. EPA.
5. (5) The department may test or have tested any coating for VOC content using 40 CFR 60, Appendix A, Method 24*. If there is a discrepancy between the results of testing for VOC content, Method 24 test results shall take precedence.
