Periodic Review of Existing Rules N.C. G.S. 150B-21.3A requires that state agencies review existing rules in the N.C. Administrative Code every 10 years on a schedule established by the Rules Review Commission. As part of the rules review process, the N.C. Department of Information Technology is required to evaluate each existing rule and make an initial determination from one of the three classifications below. Classification Description Necessary with substantive public interest The agency has received public comment on the rule within the past two years or the rule affects the property interest of the regulated public, and the agency knows or suspects that any person may object to the rule. Necessary without substantive public interest The agency determines that the rule is needed, and the rule has not had public comment in the last two years. This category includes rules that identify information that is readily available to the public, such as an address or telephone number. Unnecessary The agency determines that the rule is obsolete, redundant or otherwise not needed. Public Comment Rules will be available for public comment as they are reviewed. View a list of rules currently available for public comment. A “public comment,” as defined by G.S. 150B-21.3A(a)(5), is a written comment that objects to a rule, in whole or in part. Comments must address the content of the rule to be considered by the Rules Review Commission. All comments received will be submitted to the Rules Review Commission for consideration. Comments in the periodic review of rules process should be related to whether the public thinks NCDIT has correctly classified rules as necessary with substantive public interest, necessary without substantive public interest or unnecessary. Mailing List To receive notices regarding rules undergoing rules review that are open for public comment under G.S. 150B-21.3A by requesting to be added to the Interested Parties mailing list.
