Sec. 18.
(d) If the U.S. EPA does not object to the issuance of a Part 70 permit under subsection (c), any person may petition the U.S. EPA, within sixty (60) days after the expiration of the U.S. EPA's forty-five (45) day review period, to make such objection. Any such petition shall be based only on objections to a Part 70 permit that were raised with reasonable specificity during the public comment period provided under section 17 of this rule, unless the petitioner demonstrates that it was impracticable to raise such objections within such period or unless the grounds for such objection arose after such period. Such a petition for review does not stay the effectiveness of a permit or its requirements if the permit was issued after the end of the U.S. EPA's forty-five (45) review period and prior to a U.S. EPA objection. If the U.S. EPA objects to a Part 70 permit prior to issuance as a result of a petition filed under this subsection, the commissioner shall not issue the permit until the U.S. EPA's objection has been resolved, except that a petition for review does not stay the effectiveness of a permit or its requirements if the permit was issued after the end of the forty-five (45) day review period and prior to the U.S. EPA's objection. If the commissioner has issued a permit prior to receipt of a U.S. EPA objection under this subsection, the U.S. EPA will modify, terminate, or revoke the permit, consistent with the procedures in section 9(d) of this rule, except in unusual circumstances, and the commissioner may thereafter issue only a revised permit that satisfies the U.S. EPA's objection. In any case, the source will not be in violation of the requirement to have submitted a timely and complete application. *This document is incorporated by reference.
