Indiana Code Title 8. Utilities and Transportation § 8-1-28-19

Sec. 19. (a) Use of the procedure in this chapter is voluntary to a public utility.  The failure of a public utility to use the approval provisions of this chapter may not create a presumption of imprudence or nonrecovery in rates for environmental compliance plan costs.

(b) This chapter does not require a public utility to utilize this chapter to recover a cost or expense otherwise recoverable in the public utility's rates.  A higher standard for the recovery of such costs or for determining the appropriateness of an environmental compliance plan may not be imposed because of a public utility's election not to use the provisions of this chapter.

(c) An order of the commission approving an environmental compliance plan under this chapter may not limit or define the measures that may be proposed in a compliance plan submitted by another public utility or approved by the commission.
