Applicants must complete the appropriate Best Available Control Technology (BACT) Analysis Application documents if the proposed new construction is subject to 326 IAC 2-2-3 [PDF] Prevention of Significant Deterioration (PSD), 326 IAC 2-3-2 [PDF] Emission Offset, or 326 IAC 8-1-6 [PDF] New Facilities, General [VOC] Reduction Requirements.
New constructions subject to 326 IAC 2-2-3 include "major modifications" and "major stationary sources" as defined in 326 IAC 2-2-1(x) and (y). New constructions that are subject to 326 IAC 2-3-2 include "major modifications" and "major stationary sources" as defined in 326 IAC 2-3-1(s) and (t). New constructions that are subject to 326 IAC 8-1-6 include new facilities that have unrestricted potential VOC emissions in excess of 25 tons per year that are not subject to any of the other specific 326 IAC 8 VOC rules.
Please note that these documents need to be submitted in addition to the applicable basic documents. The BACT Analysis Application documents were created to ensure that all applicants submit complete BACT analyses in a consistent format. Submitting complete BACT analyses in a consistent format will help to reduce the time needed for IDEM, OAQ to review the permit application. These documents are consistent with the top-down BACT analysis process described in the U.S. EPA "New Source Review Workshop Manual".
The BACT Analysis Application documents Instructions explain how to complete the BACT Analysis Application documents.
