Bill
H 3585
Establishes a 15-member commission to study environmental and safety risks to municipalities from onshore wind infrastructure for offshore projects, guiding emergency planning.
Status and context
- Introduced: February 27, 2025
- Referred to: Telecommunications, Utilities and Energy
- Hearing: July 29, 2025 (1:00 PM–5:00 PM, in A-1)
- Reporting date extended: December 3, 2025 (current status shows a six-month extension as of October 27, 2025)
- Related: Similar matter previously filed in 2023-2024 (HD 5210)
Purpose and scope
- Establishes a 15-member special commission to study the potential financial, environmental, public health, and public safety risks to cities and towns and their residents from onshore electric infrastructure associated with offshore wind energy projects.
- The study covers infrastructure as it lands in and traverses Massachusetts communities, with emphasis on:
- Onshore transmission lines (underground and above-ground), substations, and related infrastructure
- Risks of electromagnetic emissions, smoke, fire, and release of oil or hazardous materials
- Impacts on public/private water supplies and the sole source aquifer
- Potential need for indemnification of municipalities for response and cleanup costs
- Risk assessments, routine audits of substations (including cybersecurity risks)
- Interagency coordination readiness for catastrophic events
- Facility-specific emergency response plans for onshore substations and similar facilities
Commission composition and governance
- Members (15 total) include:
- Chair of the Energy Facilities Siting Board (or designee)
- Chair of the Department of Public Utilities (or designee)
- Commissioner of the Department of Environmental Protection (or designee)
- Commissioner of the Department of Energy Resources (or designee)
- Commissioner of the Department of Public Health (or designee)
- Executive Director of the Massachusetts Municipal Association
- Three appointments by the Governor (one with offshore wind development experience; one to represent a city/town with a host community agreement; one with substantial public safety experience)
- Two appointments by the President of the Senate
- One appointment by the Senate Minority Leader
- Two appointments by the Speaker of the House
- One appointment by the House Minority Leader
- Eligibility: All members must have substantial knowledge or experience related to offshore wind development, municipal government, environmental contamination, public safety/health, and associated risks.
- Officers: At first meeting (and annually thereafter) the commission elects a chair, vice chair, secretary, and additional officers as needed.
Operations and reporting
- Compensation: Members receive no compensation for service but may be reimbursed for necessary travel.
- Meetings: The commission may hold meetings and public hearings at times and places it designates; public hearings are preferred in host communities for offshore wind onshore infrastructure.
- Quorum: A majority constitutes a quorum.
- Reporting timeline: A preliminary report with findings and recommended legislative/regulatory changes due within six months of the Act’s effective date; thereafter, regular reports at least every six months to the Governor, Senate and House clerks, and the Joint Committee on Economic Development and Emerging Technologies.
Implications and potential impact
- Creates an official, multi-agency, stakeholder body to assess and address risks tied to onshore infrastructure for offshore wind.
- Could inform future regulatory updates, safety standards, emergency planning, and potential state indemnification policy for municipalities.
- May shape municipal budgeting and response planning in host communities and influence cybersecurity and disaster-readiness requirements for energy infrastructure.
- The absence of compensation for commissioners means limited direct cost to state residents for this commission’s work, though staff support and logistics would be determined through the commonwealth’s processes.
Bottom line
H.3585 would establish a specialized commission to comprehensively examine and report on the risks, costs, and governance related to onshore infrastructure supporting offshore wind, with a focus on protecting municipalities, public health, safety, water resources, and environmental quality, and on coordinating state agency responses to potential catastrophic events.
