SIP Exemptions

(Last Updated: August 7, 2006) 

Unless otherwise required by the Director, SIP permits shall not be required for the following source activities. These exemptions may not be used to avoid any emission limitations or standards of the Rules for Air Quality Control Chapter 391-3-1-.02, lower the potential to emit below "major source" thresholds or to avoid any "applicable requirement" (i.e., NSPS, NESHAP, etc.) as defined in 40 CFR Part 70.2.

(j) Construction Permit Exemption for Pollution Control Projects

Projects listed in subparagraph 391-3-1-.01(qqqq)1. through 8. of these rules are exempt from the requirement to obtain a construction (SIP) permit as specified in paragraph 391-3-1-.03(1) of this rule provided that the project is not subject to the provisions of paragraph 391-3-1-.02(7), Prevention of Significant Deterioration of Air Quality, or the nonattainment new source review permitting requirements of subparagraph 391-3-1-.03(8)(c). The Director has the authority to rebut the presumption that projects listed in subparagraphs (qqqq)1. through 8. are environmentally beneficial in accordance with the criteria specified in subparagraph (qqqq) and thus exempt from the requirement to obtain a construction (SIP) permit. Owners and operators of projects exempt from the requirement to obtain a construction (SIP) permit under this subparagraph (6)(j) shall obtain an operating permit or amendment under either paragraph 391-3-1-.03(2) or 391-3-1-.03(10) of this rule, whichever is applicable, prior to commencement of operation of the project.
