LD 646 Maine House · 132nd Legislature (2025-2026)

Resolve, Establishing The Commission To Study Unregulated Storm Water Pollution

LD 646 establishes a 13-member commission to study unregulated storm water pollution in Maine. The commission, including state agency representatives and environmental/municipal stakeholders, will analyze how storm water affects coastal waters, habitats, and species, identify data gaps, and recommend policies to reduce pollution. It must submit a report with findings and suggested legislation to the Environment Committee by December 3, 2025. This study directly affects Maine's coastal ecosystems and public health by addressing pollution sources like urban development and climate change impacts. The commission's work will inform future state policies but does not enact new laws itself.
