(a) Except as provided in subsections (g) and (h) of this section, an agency, not less than thirty days prior to adopting a proposed regulation, shall (1) post a notice of its intended action on the eRegulations System, which notice shall include (A) a specified public comment period of not less than thirty days, (B) a description sufficiently detailed so as to apprise persons likely to be affected of the issues and subjects involved in the proposed regulation, (C) a statement of the purposes for which the regulation is proposed, (D) a reference to the statutory authority for the proposed regulation, (E) when, where and how interested persons may obtain a copy of the small business impact and regulatory flexibility analysis required pursuant to § 4-168a, and (F) when, where and how interested persons may present their views on the proposed regulation; (2) post a copy of the proposed regulation on the eRegulations System; (3) give notice electronically to each joint standing committee of the General Assembly having cognizance of the subject matter of the proposed regulation; (4) prior to January 1, 2017, give notice electronically or provide a paper copy notice, if requested, to all persons who have made requests to the agency for advance notice of its regulation-making proceedings; (5) provide a paper copy or electronic version of the proposed regulation to persons requesting it; and (6) prepare a fiscal note, including an estimate of the cost or of the revenue impact (A) on the state or any municipality of the state, and (B) on small businesses in the state, including an estimate of the number of small businesses subject to the proposed regulation and the projected costs, including, but not limited to, reporting, recordkeeping and administrative, associated with compliance with the proposed regulation and, if applicable, the regulatory flexibility analysis prepared under § 4-168a. The governing body of any municipality, if requested, shall provide the agency, within twenty working days, with any information that may be necessary for analysis in preparation of such fiscal note. On and after January 1, 2017, each such agency shall mail a paper copy of the notice posted pursuant to subdivision (1) of this subsection, not later than five days after posting such notice, to any person who has requested advance notice of the agency’s regulation-making proceedings on or after October 1, 2016.

(b) Except as provided in subsections (g) and (h) of this section, during the public comment period specified in subsection (a) of this section, all interested persons shall have reasonable opportunity to submit data, views or arguments in writing on the proposed regulation. The agency shall hold a public hearing on the proposed regulation if requested by fifteen persons, by a governmental subdivision or agency or by an association having not less than fifteen members, if notice of the request is received by the agency not later than fourteen days after the date of posting of the notice by the agency on the eRegulations System. The agency shall consider fully all written and oral submissions respecting the proposed regulation and revise the fiscal note prepared in accordance with the provisions of subdivision (6) of subsection (a) of this section to indicate any changes made in the proposed regulation. On and after the certification date, each agency shall post the proposed regulation and all documents prepared by the agency pursuant to this subsection and subsection (a) of this section on the eRegulations System. Prior to the certification date, each agency shall create and maintain a regulation-making record for each regulation proposed by such agency, which shall be made available to the public. No regulation shall be found invalid due to the failure of an agency to give notice to each committee of cognizance pursuant to subdivision (3) of subsection (a) of this section, provided one such committee has been so notified.

(c) If an agency is required by a public act to adopt regulations, the agency, not later than five months after the effective date of the public act or by the time specified in the public act, shall post on the eRegulations System notice of its intent to adopt regulations. If the agency fails to post the notice within such five-month period or by the time specified in the public act, the agency shall submit an electronic statement of its reasons for failure to do so to the Governor, the joint standing committee having cognizance of the subject matter of the regulations and the standing legislative regulation review committee and on and after the certification date, post such statement on the eRegulations System. The agency shall submit the required regulations to the standing legislative regulation review committee, as provided in subsection (b) of § 4-170, not later than one hundred eighty days after posting the notice of its intent to adopt regulations, or electronically submit a statement of its reasons for failure to do so to the committee.

(d) An agency may begin the regulation-making process under this chapter before the effective date of the public act requiring or permitting the agency to adopt regulations, but no regulation may take effect before the effective date of such act.

(e) After the close of the public comment period and prior to submission to the Attorney General, in accordance with § 4-169, the agency shall post on the eRegulations System a notice describing whether the agency has decided to move forward with the proposed regulation. If any comments have been received, the agency shall also post on the eRegulations System: (1) A statement of the principal reasons in support of its intended action; and (2) a statement of the principal considerations in opposition to its intended action as urged in written or oral comments on the proposed regulation and its reasons for rejecting such considerations. The agency shall distribute its response to comments electronically to all persons who have commented on the regulation and have provided a valid electronic mail address and shall mail a copy of such response to any person who has commented on the regulation and specifically requested a paper copy on or after January 1, 2017.

(f) Except as provided in subsections (g) and (h) of this section, no regulation may be adopted, amended or repealed by any agency until it is (1) approved by the Attorney General as to legal sufficiency, as provided in § 4-169, (2) approved by the standing legislative regulation review committee, as provided in § 4-170, and (3) posted on the eRegulations System by the office of the Secretary of the State, as provided in § 4-172 and § 4-173b.

(g) (1) An agency may proceed to adopt an emergency regulation in accordance with this subsection without prior notice, public comment period or hearing or upon any abbreviated notice, public comment period and hearing that it finds practicable if (A) the agency finds that adoption of a regulation upon fewer than thirty days’ notice is required (i) due to an imminent peril to the public health, safety or welfare or (ii) by the Commissioner of Energy and Environmental Protection in order to comply with the provisions of interstate fishery management plans adopted by the Atlantic States Marine Fisheries Commission or to meet unforeseen circumstances or emergencies affecting marine resources, (B) the agency states in writing its reasons for that finding, and (C) the Governor approves such finding in writing.

(2) The agency shall submit an electronic copy of the proposed emergency regulation to the standing legislative regulation review committee in the form prescribed in subsection (b) of § 4-170, together with a statement of the terms or substance of the intended action, the purpose of the action and a reference to the statutory authority under which the action is proposed. The committee may approve or disapprove the proposed emergency regulation, in whole or in part, not later than fifteen calendar days after its submission to the committee, at a regular meeting, if one is scheduled, or may, upon the call of either chairman or any five or more members, hold a special meeting for the purpose of approving or disapproving the regulation, in whole or in part. Failure of the committee to act on such regulation within such fifteen-day period shall be deemed an approval. If the committee disapproves such regulation, in whole or in part, it shall notify the agency of the reasons for its action. An approved emergency regulation shall be posted on the eRegulations System by the office of the Secretary of the State and shall be effective for a period of not longer than one hundred eighty days from the date it is approved or deemed approved and posted. Such one-hundred-eighty-day period may be extended an additional sixty days for emergency regulations described in subparagraph (A)(ii) of subdivision (1) of this subsection, provided the Commissioner of Energy and Environmental Protection requests of the standing legislative regulation review committee an extension of the renewal period at the time such regulation is submitted or not less than fifteen calendar days before the emergency regulation expires and the committee approves such extension. Failure of the committee to act on such request within fifteen calendar days shall be deemed an approval of the extension. Nothing in this subsection shall preclude an agency proposing an emergency regulation from adopting a permanent regulation that is identical or substantially similar to the emergency regulation, but such action shall not extend the effective date of the emergency regulation.

(3) If the necessary steps to adopt a permanent regulation, including the posting of notice of intent to adopt, preparation and submission of a fiscal note in accordance with the provisions of subsection (b) of § 4-170 and approval by the Attorney General and the standing legislative regulation review committee, are not completed prior to the expiration date of an emergency regulation, the emergency regulation shall cease to be effective on such expiration date.

(h) An agency may make technical amendments to an existing regulation or repeal an existing regulation to: (1) Facilitate the statutory transfer of functions, powers or duties from the agency named in the existing regulation to another agency, (2) reflect a change in the name of the agency, (3) transfer or renumber sections of the regulation to correspond with the transferring or renumbering of the section of the general statutes containing the statutory authority for the regulation, or make a correction in the numbering of the regulation, with no substantive changes made, (4) amend an existing regulation solely to conform the regulation to amendments to the general statutes, provided the amendments to the regulation do not entail any discretion by the agency, (5) update or correct contact information contained in the regulation, (6) correct spelling, grammar, punctuation, formatting or typographical errors, with no substantive changes made, or (7) repeal a regulation because the section of the general statutes under which the regulation has been adopted has been repealed and has not been transferred or reenacted. The agency may adopt any such amendments to or repeal of a regulation in accordance with the requirements of subsection (a) of this section or may proceed without prior notice, public comment period or hearing, provided the agency has posted such amendments to or repeal of the regulation on the eRegulations System. Any such amendments to or repeal of a regulation shall be submitted in the form and manner prescribed in subsection (b) of § 4-170, to the Attorney General, as provided in § 4-169, and to the standing legislative regulation review committee, as provided in § 4-170, for approval and upon approval shall be submitted to the office of the Secretary of the State for posting on the eRegulations System with, in the case of transferred or renumbered sections only, a correlated table of the former and new section numbers.

(i) No regulation adopted after October 1, 1985, is valid unless adopted in substantial compliance with this section. A proceeding to contest any regulation on the ground of noncompliance with the procedural requirements of this section shall be commenced within two years from the effective date of the regulation.
