The concurrence of the Public Utilities Regulatory Authority shall be required for approval of a plan submitted by a water company regulated by the authority. The Commissioner of Public Health shall consider the comments of the Public Utilities Regulatory Authority on any plan which may impact any water company regulated by the authority. The Commissioner of Public Health shall distribute a copy of the plan to the Commissioner of Energy and Environmental Protection and the Public Utilities Regulatory Authority. A copy of the plan shall be sent to the Secretary of the Office of Policy and Management for information and comment. A plan shall be revised at such time as the water company filing the plan or the Commissioner of Public Health determines, or at intervals of not less than six years or more than nine years after the date of the most recently approved plan. Unless the Commissioner of Public Health requests otherwise, any water company that fails to meet public drinking water supply quality and quantity obligations, as prescribed in state law or regulation, shall be required to file plan revisions six years after the date of the most recently approved plan. On and after October 1, 2009, upon the approval of a water supply plan, any subsequent revisions to such plan shall minimally consist of updates to those elements described in subsection (b) of this section that have changed after the date of the most recently approved plan provided the Commissioner of Public Health has not otherwise requested submission of an entire water supply plan.
(b) Any water supply plan submitted pursuant to this section shall evaluate the water supply needs in the service area of the water company submitting the plan and propose a strategy to meet such needs. The plan shall include: (1) A description of existing water supply systems; (2) an analysis of future water supply demands; (3) an assessment of alternative water supply sources which may include sources receiving sewage and sources located on state land; (4) contingency procedures for public drinking water supply emergencies, including emergencies concerning the contamination of water, the failure of a water supply system or the shortage of water; (5) a recommendation for new water system development; (6) a forecast of any future land sales, an identification which includes the acreage and location of any land proposed to be sold, sources of public water supply to be abandoned and any land owned by the company which it has designated, or plans to designate, as class III land; (7) provisions for strategic groundwater monitoring; (8) an analysis of the impact of water conservation practices and a strategy for implementing supply and demand management measures; (9) on and after January 1, 2004, an evaluation of source water protection measures for all sources of the water supply, based on the identification of critical lands to be protected and incompatible land use activities with the potential to contaminate a public drinking water source; and (10) a brief summary of the water company's underground infrastructure replacement practices, which may include current and future infrastructure needs, methods by which projects are identified and prioritized for rehabilitation and replacement and funding needs.
(c) For security and safety reasons, procedures for sabotage prevention and response shall be provided separately from the water supply plan as a confidential document to the Department of Public Health. Such procedures shall not be subject to disclosure under the Freedom of Information Act, as defined in section 1-200. Additionally, procedures for sabotage prevention and response that are established by municipally owned water companies shall not be subject to disclosure under the Freedom of Information Act, as defined in section 1-200.
(d) Any water supply plan, including any subsequent revisions to such plan, submitted by a water company pursuant to this section shall be accompanied by a redacted copy of such plan, or subsequent revision to such plan. When submitting a redacted copy of a water supply plan, a water company shall redact the information exempted from disclosure under subsection (e) of this section.

Upon request by the water company, such record may be reviewed by the Commissioner of Administrative Services, in consultation with the chief executive officer of the executive branch state agency or municipal water or sewage treatment entity that has custody of such record, to determine if such reasonable grounds exist.
(f) The Commissioner of Public Health, in consultation with the Commissioner of Energy and Environmental Protection and the Public Utilities Regulatory Authority, shall adopt regulations in accordance with the provisions of chapter 54. Such regulations shall include a method for calculating safe yield, the contents of emergency contingency plans and water conservation plans, the contents of an evaluation of source water protection measures, a process for approval, modification or rejection of plans submitted pursuant to this section, a schedule for submission of the plans and a mechanism for determining the completeness of the plan. The plan shall be deemed complete if the commissioner does not request additional information within ninety days after the date on which the plan was submitted or, in the event that additional information has been requested, within forty-five days after the submission of such information, except that the commissioner may request an additional thirty days beyond the time in which the application is deemed complete to further determine completeness. In determining whether the water supply plan is complete, the commissioner may request only information that is specifically required by regulation. The Department of Energy and Environmental Protection and the Public Utilities Regulatory Authority, in the case of any plan which may impact any water company regulated by that agency, shall have ninety days upon notice that a plan is deemed complete to comment on the plan.
(g) Any water company, when submitting any plan or revision or amendment of a plan after July 1, 1998, which involves a forecast of land sales, abandonment of any water supply source, sale of any lands, or land reclassification, shall provide notice, return receipt requested, to the chief elected official of each municipality in which the land or source is located, the Nature Conservancy, the Trust for Public Land and the Land Trust Service Bureau and any organization on the list prepared under subsection (b) of section 16-50c.

Such notice shall specify the location and acreage proposed for sale or reclassification as class III land and identify sources to be abandoned and shall be provided no later than the date of submission of such plan or revision. Such notice shall indicate that public comment on such plan or revision shall be received by the Commissioners of Public Health and Energy and Environmental Protection not later than sixty days after the date of notice. The Commissioner of Public Health shall take such comment into consideration in making any determination or approval under this section.
