The proposed regulations under 225 CMR 29.00 aim to streamline the siting and permitting process for small clean energy infrastructure facilities in Massachusetts, in accordance with the 2024 Climate Act. The legislation addresses barriers in the current permitting process that impede the development of clean energy necessary for achieving the state's greenhouse gas emissions reduction goals by 2050. Key provisions include a consolidated local permitting process with a 12-month timeline, enhanced community engagement, and a single appeals process, while still preserving local autonomy. The bill introduces new definitions for various clean energy facility types and establishes a framework for a Consolidated Local Permit Application, allowing applicants to seek local approvals individually or collectively.

Additionally, the bill outlines specific public health, safety, and environmental standards that must be adhered to throughout the lifecycle of the facilities, including compliance with local bylaws and state and federal laws. It mandates local governments to complete their review of applications within a 12-month timeframe, with provisions for constructive approval if they fail to do so. Key insertions include the establishment of a "Completeness Determination" process, a defined "Review" period, and "Common Conditions and Requirements for Constructive Approval." The Department of Energy Resources is tasked with providing technical assistance and conducting quarterly assessments of permit applications, ensuring that the permitting process is efficient while maintaining necessary environmental and community protections.
