Summary — S.540 (Resolve preventing the discharge of radioactive materials)

Note on sources: Metadata provided with this request contains inconsistent items (titles and sponsors that appear unrelated to the text). This summary is based on the bill text filed as Senate No. 540 (Dylan A. Fernandes) in the Massachusetts 194th General Court (2025–2026).

Main purpose

To require the Massachusetts Department of Environmental Protection (MassDEP), in consultation with the Massachusetts Department of Public Health (DPH), to examine and report on the environmental and economic impacts of discharging spent fuel pool water and other radioactive wastewater associated with nuclear plant decommissioning — and to temporarily prohibit such discharges into Commonwealth waters until 90 days after that report is issued.

Key provisions

  • Directs MassDEP, with DPH consultation, to examine and prepare a report on the potential negative environmental and economic impacts caused by discharge of spent fuel pool water and other liquid wastes from nuclear energy decommissioning. The text explicitly includes processed water or any liquid with elevated levels of radioactivity (examples named: tritium, boron).
  • Requires the report to:
    • Investigate environmental and economic impacts, including methods that increase evaporation rates;
    • Analyze impacts on consumer perception and economic effects for fishing, aquaculture, tourism, restaurants, and other sectors deemed appropriate;
    • Undertake regular monitoring of land, air, and water to determine pollution levels associated with such discharge (including by evaporation-enhancing methods);
    • Make recommendations to mitigate or avoid potential negative impacts on affected industries.
  • Imposes a temporary prohibition: no discharge of the identified materials into Commonwealth waters until 90 days after MassDEP (with DPH) issues the required report.
  • The resolve format indicates agency study/reporting plus a temporary moratorium tied to the report’s issuance.

Who is affected

  • Nuclear power plant operators and entities conducting decommissioning in or near Massachusetts waters.
  • Coastal and marine-dependent industries: commercial and recreational fishing, aquaculture, tourism, and restaurants.
  • State environmental and public health agencies (MassDEP, DPH) — tasked with study, monitoring, and recommendations.
  • Public and local governments concerned with coastal resources and public health.

Procedural / timeline notes

  • Filed as Senate No. 540 (Dylan A. Fernandes); introduced February 12, 2025.
  • Referred to the Committee on Emergency Preparedness and Management; hearing scheduled October 22, 2025 (per docket).
  • The resolve does not specify a deadline for issuance of the MassDEP/DPH report; however, the moratorium remains in effect until 90 days after that report is issued.
  • The bill establishes study and reporting duties and a temporary prohibition, but does not in itself create a permanent regulatory regime, detailed monitoring protocols, or enforcement penalties.

Potential impacts to consider

  • Could delay or constrain discharge activities tied to decommissioning until the agencies complete study and monitoring.
  • May improve state-level assessment and public transparency about environmental and economic risks.
  • Could affect timelines and costs for decommissioning projects; may influence public confidence and market behavior in fisheries and tourism depending on findings and recommendations.
