An Act relative to the use of glyphosate on public lands

Maddy summaryThis bill prohibits the use of glyphosate herbicides on Commonwealth-owned public lands, such as state parks, playgrounds, and school buildings, starting on December 31, 2023. Under the new rules, applying these herbicides is only allowed if a person holds a specific state license for research or obtains an emergency permit when there is an immediate threat to health or the environment and no other options exist. The legislation also adds a definition for glyphosate and reinforces existing requirements for proper pesticide handling and record-keeping. Finally, the Department of Food and Agriculture is tasked with creating regulations to enforce these changes within one year of the bill taking effect.

An Act providing for consumer access to and the right to practice complementary and alternative health care services

Maddy summaryThis bill creates a legal pathway for individuals to offer complementary and alternative health care services in Massachusetts without holding a state license. It defines these practitioners as people who provide non-prohibited therapies for pay but are not currently certified by the state. To protect consumers, the law requires practitioners to provide a written document before services begin that lists their credentials, explains the treatments offered, and confirms the confidentiality of client records. The bill also establishes specific limits on what these unlicensed individuals can do, such as prohibiting skin punctures, the use of anesthesia, prescribing medication, making medical diagnoses, or claiming to be a licensed health professional. These rules take effect on January 1, 2024, while ensuring that licensed medical professionals are not affected by these new provisions.

An Act to protect Massachusetts public health from PFAS

Maddy summaryThis bill creates a PFAS Remediation Trust Fund to help Massachusetts residents and local governments address contamination from per- and polyfluoroalkyl substances in drinking water, groundwater, and soil. The fund is designed to cover remediation costs for municipalities, private well owners, and public water systems without requiring additional annual appropriations from the state budget. Money for the fund will come from settlements related to claims against manufacturers of PFAS-containing aqueous film-forming foam, and any unused funds at the end of a fiscal year will roll over to the next year. The executive office of energy and environmental affairs is responsible for administering the fund and ensuring expenditures align with existing legal settlements.

An Act establishing an ecologically-based mosquito management program in the Commonwealth to protect public health

Maddy summaryThis bill establishes a new ecologically-based mosquito management program in Massachusetts to protect public health while reducing reliance on broad-spectrum pesticides. It creates a new chapter in state law that defines specific terms like "disease vector" and outlines a strategy that prioritizes prevention, surveillance, and natural controls such as predators and habitat modification. Under this program, the use of chemical pesticides is restricted to last-resort situations where mosquito populations exceed predetermined safety levels. The legislation also repeals the previous chapter governing mosquito control and directs relevant state boards to implement these new sustainable management plans.

An Act to promote safe firearm storage education and increase the well-being of students

Maddy summaryThis bill requires Massachusetts school districts to distribute annual pamphlets and provide online resources about safe firearm storage to all students and their families. The Department of Elementary and Secondary Education must create model content in consultation with public safety officials that covers the risks of minors accessing guns, secure storage requirements, and suicide prevention resources. These materials must be available in both English and Spanish to ensure accessibility for diverse households. The law aims to educate the school community on preventing unauthorized access to firearms and promoting behavioral health support.
