Indiana Code Title 13. Environment § 13-17-5-9

Sec. 9. (a) After December 31, 2006, the board may not adopt a rule under air pollution control laws that requires motor vehicles to undergo a periodic test of emission characteristics in the following counties:

(b) After December 31, 2006, 326 IAC 13-1.1 is void to the extent it applies to a county referred to in subsection (a).

(c) Unless the budget agency approves a periodic vehicle inspection program for a county referred to in subsection (a), the board shall amend 326 IAC 13-1.1 so that it does not apply after December 31, 2006, to a county referred to in subsection (a).

(d) The budget agency, after review by the budget committee, may approve in writing the implementation of a periodic vehicle inspection program for one (1) or more counties described in subsection (a) only if the budget agency determines that the implementation of a periodic vehicle inspection program in the designated counties is necessary to avoid a loss of federal highway funding for the state or a political subdivision.  The approval must specify the counties to which the periodic vehicle inspection program applies and the time during which the periodic vehicle inspection program must be conducted in each designated county.  The budget agency, after review by the budget committee, shall withdraw an approval given under this subsection for a periodic vehicle inspection program in a county if the budget agency determines that the suspension of the periodic vehicle inspection program will not adversely affect federal highway funding for the state or a political subdivision.
