Indiana Code Title 14. Natural and Cultural Resources § 14-25-5-10

Sec. 10. (a) Except as provided under subsection (b), the operator of a significant water withdrawal facility may obtain relief from a temporary order issued under section 7 of this chapter or under IC 13-2-2.6-10 (before its repeal) by filing with the director a financial responsibility bond in an amount not:

for each acre contained in the freshwater lake.  The aggregate amount of financial responsibility bond that may be assessed on the operator of a significant water withdrawal facility may not exceed fifty thousand dollars ($50,000).

(b) The director may not allow a significant water withdrawal facility to file a financial responsibility bond under subsection (a) if the department determines that a freshwater lake or an adjacent property contains an extraordinary or a unique natural resource that is likely to be irreparably damaged as a result of the lowering of the freshwater lake.  The burden of proof to establish the presence of an extraordinary or a unique natural resource rests with the department.
