Sec. 3. (a) A board may adopt a rule under IC 4-22-2 that changes a period described under section 1 of this chapter within which the commissioner must approve or deny an application:

(2) if:
(A) the general assembly enacts a statute;
(B) a board adopts a rule; or
(C) the federal government enacts a statute or adopts a regulation;
that establishes a new permit program for which a period is not described under section 1 of this chapter; or
