The bill amends the Energy Facility Siting Act in Rhode Island to enhance the regulatory framework for major energy facilities. It increases the membership of the siting board from three to five members, including representatives from various state agencies and a public member appointed by the governor. The bill recognizes "host communities," which are municipalities where major energy facilities are located, and grants them intervenor status in proceedings.

The siting board is tasked with streamlining the licensing and permitting process, emphasizing coordinated decision-making, and defining agency roles to reduce overlapping jurisdictions. The board is given the authority to appoint hearing officers for hearings related to major non-generating facilities and is required to periodically review its rules and regulations to align with the chapter's objectives.

The application process for energy facilities is detailed, mandating comprehensive project descriptions, environmental impact assessments, and public health considerations. It requires a preliminary review to ensure applications meet specified requirements before being docketed and mandates public hearings in the host community prior to the board's hearings. The bill promotes public participation and transparency by requiring notification to local councils and property owners about applications and hearings.

Additionally, the bill includes provisions for detailed cost estimates, life-cycle management plans, and alternative studies in applications. It establishes standards for the board's decision-making process, considering socio-economic and environmental impacts. New provisions also allow host communities to enforce local ordinances, provided they do not conflict with certificates or licenses issued by the board.
