H. Special rules applicable to Federal Land Managers:

~ 4’ 1. Notwithstanding any other provision of this Section, a Federal Land

Manager may present to the Director a demonstration that the emissions attribu—

ted to such new major source or major alteration to a source will have signi

ficant adverse impact on visibility or other specifically defined air quality

related values of any Federal Mandatory Class I area designated in R9-3—217.A.2.

regardless of the fact that the change in air quality resulting from emissions

attributable to such new major source or major alteration to a source In existence

will not cause or contribute to concentrations which exceed the maximum allowable
(‘~ increases for a Class I area. If the Director concurs with such demonstration,

the permit shall be denied.

2. If the owner or operator of a proposed new major source or a 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 visibility or other specifically defined air

quality related values of such areas and the Federal Land Manager so certifies

to the Director, the Director may issued a permit notwithstanding the fact that

the change in air quality resulting from emissions 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 or major alteration comply with such

emission limitations as may be necessary to assure that emissions will not cause

Increases In ambient concentrations greater than the following maximum allowable

increases over baseline concentrations for such pollutants:

Maximum Allowable Increase

Sulfur Oxide (t1l~crograms per cubic meter)

Period of exposure

• Low terrain areas:

24-hour maximum 36
