Granting the waiver does not obligate the department to approve the air permit application for the source.
NR 406.03(2)(e) (e) The source referenced in par. (b) 1. may not be initially operated until a construction permit is issued.
NR 406.03(2)(f) (f) The department may not grant a waiver for a source that requires a permit under ch. NR 405 or 408 or requires a permit to establish enforceable limitations on potential to emit to avoid permit requirements of ch. NR 405 or 408.
