The bill S.223 establishes the Water Quality, Lake Classification, and Antidegradation Study Group in Vermont, tasked with evaluating the state's water quality and classification systems. The group will review existing classified waters, assess antidegradation requirements, and examine the regulatory framework for Class A waters. It will also develop an inventory of state waters, assess compliance with the federal Clean Water Act, and recommend legislative or policy changes to enhance environmental protection and regulatory certainty. The Study Group will consist of various members, including legislators, representatives from environmental advocacy groups, and individuals from industries interacting with water quality permitting.

Additionally, the bill outlines the powers and duties of the Study Group, including the requirement to submit a report with findings and recommendations by December 15, 2026. It specifies that the group will receive administrative and legal assistance from the Agency of Natural Resources and the Office of Legislative Counsel. Compensation for members attending meetings is contingent upon the appropriation of funds in fiscal year 2027, and the Study Group will cease to exist on February 15, 2027. The act will take effect upon passage.
