(a) Notwithstanding any filing prior to the effective date of this section, each agency shall hereafter file in the state register a certified copy of all of its lawfully adopted rules which are in force on the date of such filing and all of its proposed rules which have not become effective prior to the date of such filing. All such rules and proposed rules shall be arranged, compiled, numbered and indexed in accordance with the provisions of section six of this article, and shall also include a designation of each rule as either legislative rule, interpretive rule or procedural rule. Any agency desiring to pursue promulgation of a rule proposed prior to the effective date of this section but not then yet effective, shall refile such proposed rule, following the procedure set forth in article three: Provided, That it shall not be necessary for the agency to again hold a public hearing to determine facts or public comment, but in all other respects the procedures provided for the promulgation of rules under this section shall be complied with. On or before January 1, 1983, any other agency required by law to file its rules in the state register in order for such rules to be effective shall resubmit and refile such rules in accordance with this section. If any agency fails to file a certified copy of any rule or proposed rule in accordance with this section on or before January 1, 1983, then such rule or proposed rule not so filed shall be thereafter void and unenforceable and shall be of no further force and effect except as to enforcement of its effective provisions for actions, causes or matters occurring prior to January 1, 1983.
(b) Except for such changes in the designation and numbering of a rule, including numerical references within a rule, as are required to comply with the provisions of section six of this article, no legislative rule filed under the provisions of this section may be amended in any way prior to such filing unless such amendment is made in compliance with the requirements of article three of this chapter.
