  • The Massachusetts Water Management Act Program

    The Water Management Act (M.G.L. c. 21G) became effective in March 1986, authorizing MassDEP to regulate the quantity of water withdrawn from both surface and groundwater supplies. The program uses the WMA to ensure adequate water supplies for current and future water needs.

  • Model Water Use Restriction Bylaw/Ordinance (2009)

The Model Bylaw also includes options for regulating private wells and in-ground irrigation systems.

  • Underground Storage Tank (UST) Program
    Effective January 2, 2015, new MassDEP Underground Storage Tank (UST) Regulations (310 CMR 80.00) address the registration, installation, operation, maintenance, closure and inspection of UST systems used to store petroleum fuels and hazardous substances. The UST program is a major component of the state's groundwater resource protection efforts.

    The Massachusetts Legislature transferred most responsibility for UST regulation from the Department of Fire Services (DFS) to MassDEP in 2009. The new MassDEP rules replace DFS regulations at 527 CMR 9.00, which were rescinded on January 1, 2015, although the fundamentals of the program, including most basic DFS requirements, remain the same. MassDEP has also incorporated recent federal requirements and added new provisions to ensure that UST systems are properly installed, operated and maintained; that leaks and spills are prevented and contained; that UST systems and components found to be leaking or not working properly are repaired or replaced; and any resulting environmental damage is limited, assessed and cleaned up.
