Part 18 - PREVENTION OF SIGNIFICANT DETERIORATION OF AIR QUALITY
Section R. 336.2816 - Sources impacting federal class I areas; additional requirements

(1) The department shall transmit to the United States environmental protection agency a copy of each permit application relating to a major stationary source or major modification and provide notice to the United States environmental protection agency of every action related to the consideration of the permit.

(2) If an applicant submits a permit application to the department for a proposed major stationary source or major modification that affects a federal class I area, the applicant must submit to the department and the federal land manager charged with direct responsibility for management of class I lands a demonstration of the impact the emissions from the proposed source or modification would have on the air quality related values of class I lands, including visibility. The department shall be available to consult with and provide additional information to the federal land manager during the federal land managers review of the demonstration submitted by the applicant, if necessary, to complete the review of the demonstration.

(3) If the federal land managers review of the applicants demonstration results in a finding that the emissions from the proposed major source or major modification would have an adverse impact on the air quality related values of class I areas, including visibility, notwithstanding that the change in air quality resulting from emissions from a major source or major modification would not cause or contribute to concentrations that would exceed the maximum allowable increases for a class I area, and if the department concurs with such finding, then the department shall not approve the permit application.

(4) If the department determines that the emissions from a proposed major source or major modification would cause or contribute to concentrations which would exceed the maximum allowable increases for a class I area, the department shall not approve a permit application unless the applicable requirements of Michigans state implementation plan are otherwise met and 1 of the following occurs:

(5) The department will not issue a permit affecting a class I area in which a sulfur dioxide variance was granted under R 336.2816(4)(b) or (c), unless the permit includes emission limitations necessary to assure that emissions of sulfur dioxide from the major source or major modification would not, during any day on which the otherwise applicable maximum allowable increases are exceeded, cause or contribute to concentrations which would exceed the following maximum allowable increases over the baseline concentration and to assure that emissions would not cause or contribute to concentrations which exceed the otherwise applicable maximum allowable increases for periods of exposure of 24 hours or less for more than 18 days, not necessarily consecutive, during any annual period.
