(a) Each agency shall have an officer designated as its secretary and shall file in the office of the secretary of the agency a certified copy of each rule adopted by it, including all rules, as defined in this chapter, existing on October 1, 1981. Each rule or regulation promulgated, whether the original or a revision, and all copies thereof, shall have the name or names of the author or authors, respectively, on its face. The secretary of the agency shall keep a permanent register of the rules open to public inspection.
