Indiana Administrative Code
Title 326 - AIR POLLUTION CONTROL DIVISION
Article 8 - VOLATILE ORGANIC COMPOUND RULES
Rule 1 - General Provisions
Section 1-1 - Applicability

(a) This rule contains general provisions applicable to all other rules in this article. Once a facility becomes subject to a rule within this article under any rule applicability section in this article, such facility shall remain subject to such rule notwithstanding any subsequent decrease in VOC emissions unless the provisions of subsections (b) through (d) are met. Any proposal to establish an alternative limitation or requirement other than the streamlining of multiple requirements shall be in accordance with section 5 of this rule.

(b) A facility subject to this article may be exempted by the commissioner from any of these applicability sections if the facility has an enforceable permit issued under 326 IAC 2 or a federally-approved SIP revision that permanently restricts one (1) or more facility activities that result in VOC emissions, such as production, hours of operation, or capacity utilization, such that restrictions lower actual emissions before add-on controls to a level below fifteen (15) pounds per day. Upon expiration of any facility's permit, such exemption shall also expire, and such facility shall be subject to the requirements of all applicable rules within this article, unless a renewed permit containing such exemption is issued pursuant to 326 IAC 2.

(c) The permit or other enforceable document referenced in subsection (b) shall also require a facility owner or operator to keep records to demonstrate compliance with the permit or document restrictions. If the restriction is based on actual emissions or operations, the facility owner or operator shall keep records of throughput or actual coating usage to determine compliance. If the applicability level of the rule is in terms of actual emissions per day, the facility owner or operator shall be required to keep, at a minimum, daily consumption records, certification of VOC emission rates, and daily calculation of VOC emissions. If the rule specifies an applicability level based on potential emissions per year, the permit or enforceable document shall restrict actual production, hours of operation, and/or capacity utilization on a monthly basis, and the facility owner or operator shall be required to keep, at a minimum, daily consumption records, certification of VOC emission rates, and monthly calculations of VOC emissions.

(d) All permits, renewed permits, and other enforceable documents referenced in subsection (b) shall be submitted to the U.S. EPA as SIP revisions.
