Ind. Code § 4-3-22-13

(c) In preparing a cost benefit analysis under this section, the OMB shall consider in its analysis any verified data provided voluntarily by interested parties, regulated persons, and nonprofit corporations whose members may be affected by the proposed rule. A cost benefit analysis prepared under this section is a public document, subject to the following:

(1) This subsection does not empower the OMB or an agency to require an interested party or a regulated person to provide any materials, documents, or other information in connection with a cost benefit analysis under this section. If an interested party or a regulated person voluntarily provides materials, documents, or other information to the OMB or an agency in connection with a cost benefit analysis under this section, the OMB or the agency, as applicable, shall ensure the adequate protection of any: (A) information that is confidential under IC 5-14-3-4; or (B) confidential and proprietary business plans and other confidential information. If an agency has adopted rules to implement IC 5-14-3-4, interested parties and regulated persons must submit the information in accordance with the confidentiality rules adopted by the agency to ensure proper processing of confidentiality claims. The OMB and any agency involved in proposing the rule, or in administering the rule upon the rule's adoption, shall exercise all necessary caution to avoid disclosure of any confidential information supplied to the OMB or the agency by an interested party or a regulated person. (2) The OMB shall make the cost benefit analysis and other related public documents available to interested parties, regulated persons, and nonprofit corporations whose members may be affected by the proposed rule at least thirty (30) days before presenting the cost benefit analysis to the governor and the legislative council under subsection (a). (d) If the OMB or an agency is unable to obtain verified data for the cost benefit analysis described in subsection (c), the OMB shall state in the cost benefit analysis which data were unavailable for purposes of the cost benefit analysis. (e) If the OMB finds that a proposed rule is: (1) an adoption or incorporation by reference of a federal law, regulation, or rule that has no substantive effect on the scope or intended application of the federal law or rule; or (2) a technical amendment with no substantive effect on an existing Indiana rule; the OMB may not prepare a cost benefit analysis of the rule under this section. The agency shall submit the proposed rule to the OMB with a statement explaining how the proposed rule meets the requirements of this subsection. If the OMB finds that the rule meets the requirements of this subsection, the OMB shall provide its findings to the governor and to the legislative council in an electronic format under IC 5-14-6. If the agency amends or modifies the proposed rule after the OMB finds that a cost benefit analysis may not be prepared for the rule, the agency shall resubmit the proposed rule to the OMB either for a new determination that the rule meets the requirements of this subsection, or for the OMB to prepare a cost benefit analysis of the rule under this section.
