The Codifier of Rules must compile all rules into a Code known as the North Carolina Administrative Code. The format and indexing of the Code must conform as nearly as practical to the format and indexing of the North Carolina General Statutes. The Codifier must publish printed copies of the Code and may publish the Code in other forms. The Codifier may authorize and license the private indexing, marketing, sales, reproduction, and distribution of the Code. The Codifier must keep superseded rules.
