An Act relative to equitable protection of clean water

This bill establishes new rules for upgrading septic systems in Massachusetts to reduce nitrogen pollution in sensitive water areas. It prevents the Department of Environmental Protection from mandating upgrades to existing systems unless specific conditions are met, such as the availability of affordable remote monitoring technology and the establishment of regional management entities. Additionally, the legislation creates a zero-interest loan program to help municipalities fund wastewater management projects, offering long-term repayment terms and prioritizing towns with more nitrogen-sensitive areas. The bill also provides exemptions from permitting requirements for communities that have approved management plans or have already achieved significant nitrogen reduction goals.
