If the owneroroperatorofa proposed newmajor source ora source for which major alteration is proposed demonstrates to the Federal Land Manager that the emissions attributable to such major source or major alteration will have no significant adverse impact on the visibilityorother specifically defined air quality related values of such areas and the Federal Land Managerso certifies to the Director, the Directormay issueda permit notwithstanding the fact that the change in air quality resulting fromemissions attributable to such new major source or major alteration will cause or contribute to concentrations which exceed the maximum allowable increases for a Class I area. Such a permit shall require that such new major source ormajor alteration complywith such emission limitations as may be necessary to assure that emissions will not cause Increases In ambient concentrations greaterthan the following maximum allowable increases over baseline concentrations forsuch pollutants: Maximum Allowable Increase Sulfur Oxide (t1l~crograms per cubic meter) Period of exposure
