The Prevention of Significant Deterioration/Emission Offset Checklist must be completed by an applicant if the proposed new construction is subject to 326 IAC 2-2, Prevention of Significant Deterioration (PSD), or 326 IAC 2-3, Emission Offset. New constructions subject to 326 IAC 2-2 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 include "major modifications" and "major stationary sources" as defined in 326 IAC 2-3-1(s) and (t).

Please note that these forms need to be submitted in addition to the applicable basic forms.

The Prevention of Significant Deterioration/Emission Offset Checklist Instructions explain how to complete the Prevention of Significant Deterioration/ Emission Offset Checklist.

Due to the wide variety of software and print drivers being used, you may find that some files are formatted incorrectly when you open them. For example there may be extra spaces and page numbers may be incorrect. IDEM is working to correct this problem, but in the meantime you may continue to use the forms even though some may have formatting errors.
