Comparison: State vs. Federal

Rules. Massachusetts's aboveground storage tank (AST) requirements apply to all tanks greater than 10,000 gallons (gal) storing any fluid other than water and provide standards for construction, maintenance, and use.

Massachusetts has adopted the National Fire Protection Association Model Code (NFPA 1, 2012 Edition) with Massachusetts amendments under the Massachusetts Fire Prevention Code, which authorizes the state's regulations for tanks and containers establishing AST design, construction, installation, testing, and maintenance requirements.

A spill prevention control and countermeasure (SPCC) plan is required for ASTs of a certain capacity that contain oil. See the national section SPILL PREVENTION—SPCC PLAN for additional plan guidance.

See the state section UNDERGROUND STORAGE TANKS for a summary of the state's underground storage tank (UST) regulatory program.

Administration and enforcement. The Department of Fire Services (DFS) and local fire departments are responsible for the administration and enforcement of Massachusetts's AST programs.
