Sec. 16-50j. Connecticut Siting Council. Membership. Regulations. Consultation with state agencies. (a) There is established the Connecticut Siting Council, hereinafter referred to in this chapter as the “council”, which shall be within the Department of Energy and Environmental Protection for administrative purposes only.

(b) Except as provided in subsection (c) of this section, the council shall consist of: (1) The Commissioner of Energy and Environmental Protection, or the commissioner's designee; (2) the chairperson of the Public Utilities Regulatory Authority, or the chairperson's designee; (3) one designee of the speaker of the House and one designee of the president pro tempore of the Senate; and (4) five public members, to be appointed by the Governor, at least two of whom shall be experienced in the field of ecology, and all five of whom shall, consistent with the provisions of section 4-9a, have no substantial financial interest in, not be employed in or by, and not be professionally affiliated with any (A) utility, (B) facility, (C) hazardous waste facility, as defined in section 22a-115, or (D) ash residue disposal area, and shall have had no professional affiliation with any such utility, facility, hazardous waste facility or ash residue disposal area for three years preceding such public member's appointment to the council.

(c) For proceedings under chapter 445, the council shall consist of (1) the Commissioners of Public Health and Emergency Services and Public Protection or their designated representatives; (2) the designees of the speaker of the House of Representatives and the president pro tempore of the Senate as provided in subsection (b) of this section; (3) the five public members as provided in subsection (b) of this section; and (4) four ad hoc members, appointed by the chief elected official of the municipality each such member represents, three of whom shall be electors from the municipality in which the proposed facility is to be located and one of whom shall be an elector from a neighboring municipality likely to be most affected by the proposed facility.

(d) For the appointment of ad hoc members in accordance with subsection (c) of this section, the municipality most affected by the proposed facility shall be determined by the permanent members of the council. If any one of the five public members or of the designees of the speaker of the House of Representatives or the president pro tempore of the Senate resides (1) in the municipality in which a hazardous waste facility is proposed to be located for a proceeding concerning a hazardous waste facility or in which a low-level radioactive waste facility is proposed to be located for a proceeding concerning a low-level radioactive waste facility, or (2) in the neighboring municipality likely to be most affected by the proposed facility, the appointing authority shall appoint a substitute member for the proceedings on such proposal. If any appointee is unable to perform such appointee's duties on the council due to illness, or has a substantial financial or employment interest which is in conflict with the proper discharge of the appointee's duties under this chapter, the appointing authority shall appoint a substitute member for proceedings on such proposal. An appointee shall report any substantial financial or employment interest which might conflict with the proper discharge of the appointee's duties under this chapter to the appointing authority who shall determine if such conflict exists. If any state agency is the applicant, an appointee shall not be deemed to have a substantial employment conflict of interest because of employment with the state unless such appointee is directly employed by the state agency making the application. Ad hoc members shall continue their membership until the council issues a letter of completion of the development and management plan to the applicant.

(e) The chairperson of the council shall be appointed by the Governor from among the five public members appointed by the Governor, with the advice and consent of the House or Senate, and shall serve as chairperson at the pleasure of the Governor.

(f) The public members of the council, including the chairperson, the members appointed by the speaker of the House and president pro tempore of the Senate and the four ad hoc members specified in subsection (c) of this section, shall be compensated for their attendance at public hearings, executive sessions, or other council business as may require their attendance at the rate of two hundred dollars, provided in no case shall the daily compensation exceed two hundred dollars.

(g) The council shall employ such employees as may be necessary to carry out the provisions of this chapter, and such employees shall, in the aggregate, have sufficient expertise in engineering and financial analysis to carry out the provisions of this chapter.

(h) The council shall, in addition to its other duties prescribed in this chapter, adopt, amend, or rescind suitable regulations to carry out the provisions of this chapter and the policies and practices of the council in connection therewith, and appoint and prescribe the duties of such staff as may be necessary to carry out the provisions of this chapter. The chairperson of the council, with the consent of five or more other members of the council, may appoint an executive director, who shall be the chief administrative officer of the Connecticut Siting Council. The executive director shall be exempt from classified service.

(i) Prior to commencing any hearing pursuant to section 16-50m, the council shall consult with and solicit written comments from (1) the Departments of Energy and Environmental Protection, Public Health, Agriculture, Economic and Community Development and Transportation and the Council on Environmental Quality, the Public Utilities Regulatory Authority, the Office of Policy and Management and the Office of Consumer Counsel, and (2) in a hearing pursuant to section 16-50m, for a facility described in subdivision (3) of subsection (a) of section 16-50i, the Department of Emergency Services and Public Protection, the Department of Administrative Services, the Labor Department and the Office of Consumer Counsel. Copies of such comments shall be made available to all parties prior to the commencement of the hearing. Subsequent to the commencement of the hearing, said departments, Council on Environmental Quality, authority and offices may file additional written comments with the Connecticut Siting Council within such period of time as the Connecticut Siting Council designates. All such written comments shall be made part of the record, as provided in section 16-50o. Said departments, Council on Environmental Quality, authority and offices shall not enter any contract or agreement with any party to the proceedings or hearings described in this section or section 16-50p that requires said departments, Council on Environmental Quality, authority or offices to withhold or retract comments, refrain from participating in or withdraw from said proceedings or hearings.

Certificates shall not be required for (1) fuel cells built within the state with a generating capacity of two hundred fifty kilowatts or less, or (2) fuel cells built out of state with a generating capacity of ten kilowatts or less. Any facility with respect to which a certificate is required shall thereafter be built, maintained and operated in conformity with such certificate and any terms, limitations or conditions contained therein. Notwithstanding the provisions of this chapter or title 16a, the council shall, in the exercise of its jurisdiction over the siting of generating facilities, approve by declaratory ruling (A) the construction of a facility solely for the purpose of generating electricity, other than an electric generating facility that uses nuclear materials or coal as fuel, at a site where an electric generating facility operated prior to July 1, 2004, and (B) the construction or location of any fuel cell, unless the council finds a substantial adverse environmental effect, or of any customer-side distributed resources project or facility or grid-side distributed resources project or facility with a capacity of not more than sixty-five megawatts, as long as: (i) Such project meets air and water quality standards of the Department of Energy and Environmental Protection, (ii) the council does not find a substantial adverse environmental effect, and (iii) for a solar photovoltaic facility with a capacity of two or more megawatts, to be located on prime farmland or forestland, excluding any such facility that was selected by the Department of Energy and Environmental Protection in any solicitation issued prior to July 1, 2017, pursuant to section 16a-3f, 16a-3g or 16a-3j, the Department of Agriculture represents, in writing, to the council that such project will not materially affect the status of such land as prime farmland or the Department of Energy and Environmental Protection represents, in writing, to the council that such project will not materially affect the status of such land as core forest. In conducting an evaluation of a project for purposes of subparagraph (B)(iii) of this subdivision, the Departments of Agriculture and Energy and Environmental Protection may consult with the United States Department of Agriculture and soil and water conservation districts. In addition to all other requirements for the issuance of a certificate, the council shall not issue a certificate for a facility described in subparagraph (B)(iii) of this subdivision unless the applicant for such certificate furnishes a bond to cover all costs associated with the decommissioning of such facility and the restoration of such prime farmland, including, but not limited to, an inspection by a qualified soil scientist or other agricultural soils professional to assess and assure that the soils of such prime farmland are restored and will be suitable for farming. Such an assessment shall include, but need not be limited to, consideration of topsoil and subsoil depths, soil compaction, alteration in surface and subsurface drainage, erosion and sedimentation control measures and soil fertility. Such decommissioning bond requirement shall also apply to any such two-megawatt or more solar photovoltaic facility that is approved by declaratory ruling.

(b) A certificate may be transferred, subject to the approval of the council, to a person who agrees to comply with the terms, limitations and conditions contained therein. The council shall not approve any such transfer if it finds that such transfer was contemplated at or prior to the time the certificate was issued and such fact was not adequately disclosed during the certification proceeding.

(c) A certificate issued pursuant to this chapter may be amended as provided in this chapter.

(d) This chapter shall apply to any facility described in subdivisions (1) to (3), inclusive, of subsection (a) of section 16-50i, the construction of which is commenced on or after April 1, 1972, and to any such facility the construction of which is approved by a municipality that has commenced the sale of bonds or bond anticipation notes on or after April 1, 1972, the proceeds or part of the proceeds of which are to finance such construction.

This chapter shall apply to any facility described in subdivisions (5) and (6) of said subsection, the construction of which is commenced on or after October 1, 1977, and to any such facility the construction of which is approved by a municipality that has commenced the sale of bonds or bond anticipation notes on or after October 1, 1977, the proceeds or part of the proceeds of which are to finance such construction. This chapter shall apply to the modification of a facility described in subdivisions (1) to (3), inclusive, of said subsection (a) for which construction is commenced on or after April 1, 1972, modifications of a facility described in subdivision (4) of said subsection (a) for which construction is commenced on or after July 1, 1983, and modifications of a facility described in subdivisions (5) and (6) of said subsection (a) of section 16-50i, for which construction is commenced on or after October 1, 1977, whenever such modification either alone or in combination with existing or other proposed facility modifications may, as determined by the council, have a substantial adverse environmental effect. This chapter shall not apply to any matter over which any agency, department or instrumentality of the federal government has exclusive jurisdiction, or has jurisdiction concurrent with that of the state and has exercised such jurisdiction, to the exclusion of regulation of such matter by the state.

(e) Any person intending to construct a facility excluded from one or more provisions of this chapter may, to the extent permitted by law, elect to waive such exclusion by delivering notice of such waiver to the council. Such provisions shall thereafter apply to each facility identified in such notice from the date of its receipt by the council.

If any such project alternative is not preferred by such company or owner, such company or owner shall provide a detailed, written explanation comparing the cost-effectiveness and appropriateness of the project alternative with such project preferred by such company or owner and submit such explanation with such application.

(3) If any project alternative submitted pursuant to this subsection proposes to utilize any advanced conductor, grid-enhancing technology or nontransmission alternative, and such project alternative (A) is not less cost effective than the project preferred by such company or owner, (B) provides the same or increased electric system reliability benefits to solve the identified need in comparison to such preferred project, and (C) has similar environmental and community impacts as such preferred project, as determined by the Connecticut Siting Council, the council shall give preference to such project alternative when determining whether to approve such preferred project or project alternative.

(4) An electric distribution company may seek a waiver of the requirements of subdivision (1) of subsection (b) of this section, in whole or in part, if (A) the use of advanced conductors, grid-enhancing technologies or nontransmission alternative technologies in a project to construct or materially modify any facility described in subdivision (1) or (4) of subsection (a) of section 16-50i is impossible or impracticable to solve an identified need, (B) such proposed project is subject to a regional transmission planning or review process approved by the Federal Energy Regulatory Commission that adequately considers the implementation of such conductors or technologies, or (C) a project has been evaluated by the commissioner and the Office of Consumer Counsel pursuant to subsection (d) of this section. To obtain such waiver, such company shall submit a waiver application to the commissioner in a form and manner prescribed by the commissioner. Such waiver application shall specify the conditions that satisfy the requirements of subparagraph (A), (B) or (C) of this subdivision. The commissioner, after consultation with the Office of Consumer Counsel, may waive the requirement to submit such alternative or alternatives pursuant to subdivision (1) of subsection (b) of this section to the Connecticut Siting Council. The commissioner shall accept or deny a waiver application submitted pursuant to this subdivision not more than sixty days after receipt. Any such application not accepted or rejected by the commissioner within said sixty-day period shall be deemed granted.

(5) An electric distribution company may request, and the commissioner may grant, a revocable general waiver of the requirements of this subsection for any projects subject to a regional transmission planning or review process approved by the Federal Energy Regulatory Commission that adequately considers advanced conductors, grid-enhancing technologies or nontransmission alternative technologies. The commissioner shall accept or deny a waiver application submitted pursuant to this subdivision not more than sixty days after receipt.

(c) Each electric distribution company and transmission owner shall include in the annual report required by subsection (a) of section 16-50r: (1) A schedule of any planned construction or material modification of any facility described in subdivision (1) or (4) of subsection (a) of section 16-50i for the next ten years, including a description, as appropriate for the project's current development stage, and, to the extent available, of the need for and scope of the project, cost estimates, whether and how any advanced conductor, grid-enhancing technologies or nontransmission alternative technologies may be considered to address the identified need, and any other information reasonably requested by the commissioner or the Office of Consumer Counsel that pertains to the projects identified in the annual report, (2) data concerning any construction or material modification of any facility described in subdivision (1) or (4) of subsection (a) of section 16-50i placed in service by such company in the year preceding such report, including both final costs, to the extent available, and estimated costs of the project at each relevant design stage, (3) the original estimated in-service date of the facility, and (4) any other information reasonably requested by the commissioner or the Office of Consumer Counsel pertaining to projects disclosed in such report. For the first filing after October 1, 2025, each electric distribution company shall provide the information required by subdivision (2) of this subsection for any facility placed into service by such company or owner on or after January 1, 2022. To the extent any such information is unavailable, the electric distribution company shall notify the commissioner and the Office of Consumer Counsel and attempt to reach a resolution acceptable to each party concerning the request for information.

(d) (1) Not more than one hundred eighty days after any annual filing required pursuant to subsection (c) of this section, the commissioner, in consultation with the Office of Consumer Counsel, shall determine and notify an electric distribution company whether any facility listed for construction or material modification requires further evaluation, considering factors including, but not limited to, (A) whether the proposed facility is subject to a transmission planning or review process of the regional independent system operator or a substantially similar process, (B) the age or condition of the underlying facility, (C) the scope and estimated cost of the proposed project, (D) whether the proposed project is responsive to needs identified through proactive transmission planning by the regional independent system operator, and (E) whether and how advanced conductors, grid-enhancing technologies and nontransmission alternatives: (i) Are proposed to be utilized in the proposed project, (ii) can reduce environmental or aesthetic impacts, and (iii) can feasibly solve the underlying need identified by the electric distribution company in part or in whole. Prior to determining that a project to construct or materially modify a facility requires further evaluation pursuant to this subdivision, the commissioner and Office of Consumer Counsel shall provide the electric distribution company with the opportunity to provide evidence that such project requires no further evaluation pursuant to this subdivision.

(2) If an evaluation is conducted pursuant to subdivision (1) of this subsection, upon notice to the electric distribution company, the commissioner and the Office of Consumer Counsel shall evaluate a proposed project based upon factors including: (A) The reasonableness of the need identified by the electric distribution company justifying the proposed facility; (B) the reasonableness of the proposed scope of the project, including the timing of the proposed investments; (C) whether the electric distribution company's proposed solution is the most cost-effective solution to the identified need or whether alternative solutions, including advanced conductors, grid-enhancing technologies or nontransmission alternatives, exist that could more cost-effectively provide the same or increased electric system reliability benefits to resolve the identified need in whole or in part; (D) the costs of the proposed project and any potential alternatives identified as part of the evaluation; (E) whether cost-effective opportunities exist for the proposed project to be modified to account for future demand growth or other variables that could mitigate the need for the electric distribution company to conduct construction activities on the same facility prior to the end of the useful life; and (F) any other factors that the commissioner or the Office of Consumer Counsel reasonably determine are necessary to evaluate for a specific project.

(3) Not less than twice per year, the commissioner and the Office of Consumer Counsel shall meet with each electric distribution company to discuss and receive input on any facilities that are currently under evaluation pursuant to this section.

(4) (A) The commissioner and the Office of Consumer Counsel shall jointly prepare a report detailing the factors for evaluation listed in subdivision (2) of this subsection.

(B) Any evaluation by the department or the Office of Consumer Counsel and any draft report resulting from that evaluation must be completed and shared with the electric distribution companies not later than ninety days prior to an electric distribution company's filing of an application or petition before the Connecticut Siting Council; provided, however, that the electric distribution company informs the department and the Office of Consumer Counsel of the anticipated filing date not less than twelve months in advance of such filing date.

(C) The commissioner shall file any final report developed pursuant to this subsection in the relevant proceeding of the Connecticut Siting Council concerning the proposed project. The Connecticut Siting Council shall give appropriate consideration to such report in making its determination on the proposed project.

(5) An electric distribution company may request, and the commissioner may grant, a revocable general waiver of the requirements of this subsection for any projects subject to a regional transmission planning or review process approved by the Federal Energy Regulatory Commission. The commissioner shall accept or deny a waiver application submitted pursuant to this subdivision not more than sixty days after receipt.

(e) Each electric distribution company or transmission owner shall provide data, communications and information requested by the commissioner or the Office of Consumer Counsel in connection with any evaluation pursuant to this section, subject to enforcement under section 22a-6. Responses to any such requests shall be shared with both the department and the Office of Consumer Counsel.

(f) Beginning on January 1, 2027, and every five years thereafter, each electric distribution company and transmission owner shall file a report concerning their compliance with the provisions of this section with the Public Utilities Regulatory Authority. The authority shall transmit a copy of each such report to the regional independent system operator, as defined in section 16-1, and, in accordance with the provisions of section 11-4a, the joint standing committee of the General Assembly having cognizance of matters relating to energy and technology.

(g) Any proprietary commercial or proprietary financial information of an electric distribution company or transmission owner provided pursuant to this section shall be confidential and protected by the commissioner and the Office of Consumer Counsel and be exempt from public disclosure pursuant to subsection (b) of section 1-210.
