Sec. 1. (a) Except as provided in this section and section 10 of this chapter, a rule expires January 1 of the fifth year after the year in which the rule takes effect, unless the rule expires or is repealed on an earlier date. Except for an amendment made under IC 4-22-2-38, the expiration date of a rule under this section is extended each time that a rule amending or readopting an unexpired rule takes effect. The rule, as amended or readopted, expires on January 1 of the fifth year after the year in which the amendment or readoption takes effect.

     (b) If the latest version of a rule became effective:

(1) in calendar year 2017, the rule expires not later than January 1, 2024;

(2) in calendar year 2018, the rule expires not later than January 1, 2025;

(3) in calendar year 2019, the rule expires not later than January 1, 2026; or

(4) in calendar year 2020, the rule expires not later than January 1, 2027.

     (c) If the latest version of a rule became effective before January 1, 2017, and:

(1) the rule was adopted by an agency established under IC 13, the rule expires not later than January 1, 2025;

(2) the rule was adopted by an agency established under IC 16, the rule expires not later than January 1, 2026; or

(3) the rule was adopted by an agency not described in subdivision (1) or (2), the rule expires not later than January 1, 2027.

     (d) A readoption rulemaking action under IC 4-22-2.5 (before its repeal) or IC 13-14-9.5 (before its repeal) that became effective before July 1, 2023, is validated to the same extent as if the rulemaking action had been conducted under the procedures in this chapter.

     (e) The determination of whether an administrative rule expires under this chapter shall be applied at the level of an Indiana Administrative Code section.
