The bill S.223 proposes the establishment of the Water Quality, Lake Classification, and Antidegradation Study Group in Vermont. This group is tasked with reviewing and evaluating the state's existing statutory and regulatory frameworks related to water quality and classification. The Study Group will assess whether the current regulations are sufficient and will make recommendations for legislative or policy changes aimed at enhancing environmental protection and public interests concerning Vermont's waters. The group will consist of various members, including legislators, representatives from the Department of Natural Resources, environmental advocacy groups, and business sectors that interact with water quality permitting.

The Study Group will have specific powers and duties, including developing an inventory of water classification designations, assessing compliance with the federal Clean Water Act, identifying threats to water quality, and evaluating the adequacy of existing frameworks for Class A waters. They will also recommend necessary legislative amendments and revisions to water quality rules and policies. The group is required to submit a report with findings and recommendations to the General Assembly by January 15, 2027, and will cease to exist on February 1, 2027. The bill also outlines provisions for compensation and reimbursement for members attending meetings.
