2)         The emission source belongs to a category of emission sources having a compliance date of December 31, 1982 or later under 35 Ill. Adm. Code 215;

3)         The use of an ACS will result in either greater or faster overall emission reductions than would otherwise be achieved; and

4)         Such extension is consistent with the requirements of the Clean Air Act.
