Old Oil Tank in Your Massachusetts House? Removal and Insurance
Old basement and buried heating-oil tanks worry buyers, lenders and insurers because a leak can turn into an expensive environmental cleanup. In Massachusetts, removing a tank needs a local fire department permit, and oil lines must have a safety valve or protective sleeve. Most standard homeowners policies don't cover oil spill cleanup unless you ask for the optional coverage.
What to look for
- Fill pipe or vent pipe sticking out of the ground or siding with no tank in sight
- Rust, weeping or wet spots on a basement tank
- Oil smell in the basement or yard
- Dead patches of grass or oily sheen near a buried tank
- Tank legs that are rusted or unstable

Massachusetts rules to know
- Local fire departments issue permits for tank removal and the Department of Fire Services regulates residential tanks; a tank can be left in place only if removal would endanger the house's structure and the fire department approves (source: mass.gov)
- Under 527 CMR 9.02, a tank permanently disconnected or unused for 24 months must be removed; for example, the Lee Fire Department requires a permit, inspection and 24-hour notice, plus a soil sample for underground tanks (source: leema.gov)
- MGL c.148 s.38J requires oil supply lines to have a non-metallic sleeve or an oil safety valve at the tank, certified by a licensed oil burner technician (source: law.justia.com)
- Chapter 453 of the Acts of 2008 requires insurers to make available heating-oil release coverage of at least $50,000 for cleanup and $200,000 for third-party liability, with a deductible of no more than $1,000 (source: malegislature.gov)
- Petroleum releases above certain amounts must be reported to MassDEP and the local fire department; leaks over 10 gallons found during removal must be reported (mass.gov; berkshirerealtors.net)
Who to call
- Your local fire department to get the tank removal permit and schedule the inspection
- A licensed oil burner technician to service or certify the line; verify a DFS license at mass.gov (lookup: madfs.mylicense.com)
- A tank removal contractor who knows Massachusetts rules and carries insurance
- If there's contamination, a Licensed Site Professional (LSP) and MassDEP; and your insurance agent to ask about oil spill coverage
DIY or hire a pro?
Don't cut, move or drain a tank yourself. Removal needs a fire department permit and inspection, and any sign of a leak means calling professionals and reporting it as required.
If fixing it is more than you want to take on
Removing an old tank before listing (and replacing it with a new aboveground tank if you still heat with oil) usually makes a sale much easier. If there's a known leak and cleanup, you can sell as-is with full disclosure, but many buyers and lenders will walk away. A cash buyer can take on the tank or cleanup, but the price will reflect that risk and be well below a clean-property price.

Common questions
Does homeowners insurance cover oil tank leaks in Massachusetts?
Usually not unless you added the optional heating-oil coverage. Massachusetts insurers must offer it, but only a small share of oil-heat homeowners have bought it.
Do I need a permit to remove an oil tank in Massachusetts?
Yes, you need a permit from your local fire department, and the removal must be inspected.
Do I have to remove an unused oil tank?
Under the state fire code, a tank disconnected or unused for 24 months must be removed.
How much does oil tank removal cost?
Nationally about $400 to $1,000 for a basement tank and $1,500 to $3,000 for a buried tank, plus testing and any cleanup.
What is an oil safety valve and is it required?
It's a valve at the tank end of the oil line that stops flow if the line breaks. Massachusetts law requires either the valve or a protective sleeve on oil lines.
