(a) The Regional Administrator shall provide notice of any permit application for a proposed major PSD stationary source or major PSD modification the emissions from which would affect a Class I area to the Federal Land Manager, and the Federal official charged with direct responsibility for management of any lands within such area. The Regional Administrator shall provide such notice promptly after receiving the application.

(b) Any demonstration which the Federal Land Manager wishes to present under 40 CFR 52.21(q)(3), and any variances sought by an owner or operator under § 52.21(q)(4) shall be submitted in writing, together with any necessary supporting analysis, by the end of the public comment period under § 124.10 or § 124.118.
