Affected: IC 13-17

Sec. 2. (a) This rule shall apply to stationary sources located in Lake, Porter, Clark, or Floyd County that emit or have the potential to emit volatile organic compounds (VOCs) at levels equal to or greater than twenty-five (25) tons per year (tpy) in Lake and Porter Counties and one hundred (100) tpy in Clark and Floyd Counties. This rule shall also apply to sources that have coating facilities which emit or have the potential to emit a total equal to or greater than ten (10) tpy of VOCs in Floyd, Clark, Lake, or Porter County. In determining whether the thresholds in this section are exceeded, the owner or operator of a source shall include the total potential VOC emissions from the following facilities:

1. (1) Facilities of the type identified by the following rules, but with actual emissions below the applicability levels of those rules:

   1. (A) 326 IAC 8-2, concerning surface coating operations.
   2. (B) 326 IAC 8-3, concerning organic solvent degreasing operations.
   3. (C) 326 IAC 8-4, concerning petroleum operations.
   4. (D) 326 IAC 8-5, concerning miscellaneous operations.

2. (2) Facilities of the following types:

   1. (A) Fuel combustion facilities, including process heaters and furnaces.
   2. (B) Wastewater treatment plants, excluding industrial wastewater treatment operations as defined in section 1(6) of this rule.
   3. (C) Coke ovens, including byproduct ovens.
   4. (D) Barge loading facilities.
   5. (E) Jet engine test cells.
   6. (F) Iron and steel production facilities.
   7. (G) Vegetable oil processing facilities.

3. (3) All other facilities with potential VOC emissions, hereafter referred to as affected facilities except those covered by the rules cited in clauses (A) through (D) and those belonging to source categories listed in clauses (E) through (Q) as follows:

   1. (A) 326 IAC 8-2.
   2. (B) 326 IAC 8-3.
   3. (C) 326 IAC 8-4.
   4. (D) 326 IAC 8-5.
   5. (E) Synthetic organic chemical manufacturing industry (SOCMI) distillation.
   6. (F) SOCMI reactors.
   7. (G) Offset lithography.
   8. (H) Batch processors.
   9. (I) Industrial wastewater treatment operations.
   10. (J) Plastic parts coating for business machines.
   11. (K) Plastic parts coating for automobiles.
   12. (L) Wood furniture coating.
   13. (M) Aerospace coating.
   14. (N) Auto body refinishing.
   15. (O) Ship building and ship repair.
   16. (P) Cleanup solvents.
   17. (Q) Volatile organic liquids storage.

(b) Facilities of the types listed in subsection (a)(1) through (a)(2) are exempt from the emission limit requirements of section 3 of this rule.

(c) Coating facilities that have aggregate potential emissions greater than ten (10) tpy and less than twenty-five (25) tpy in Lake and Porter Counties and coating facilities with aggregate potential emissions greater than forty (40) tpy and less than one hundred (100) tpy in Clark and Floyd Counties shall comply with the certification, record keeping, and reporting requirements of section 6 of this rule.

(d) Affected facilities are subject to the requirements of section 3 of this rule unless the source's actual emissions have been limited on or before May 31, 1995, to below twenty-five (25) tpy in Lake and Porter Counties and one hundred (100) tpy in Clark and Floyd Counties through federally enforceable production or capacity limitations in an operating permit. Until such time as 326 IAC 2-8 has been approved by the U.S. EPA, the operating permit will be submitted to the U.S. EPA by the department as a SIP revision.
