Oil Tank Leak Cleanup Indoors or Outside

Leaky oil tank (C) Daniel FriedmanFirst stop the oil tank leak if you can.

  • If the leak is in oil supply piping to the oil burner, turn off the oil supply line at the oil tank or for a buried oil tank, turn off the oil safety valve or shutoff valve where the oil piping enters the building.
  • If the leak is in an above-ground oil storage tank it may be possible to temporarily stop a pinhole leak using a special plumbing screw and neoprene washer but be careful: poking around at a thin rusted oil tank can, if you're not careful, make a hole larger and the leak worse.
  • If the leak is in a buried oil storage tank you may be able to reduce the total leakage and thus reduce the environmental damage and thus reduce the ultimate cost of the oil spill cleanup by having the oil tank pumped out by your oil company.

Next Report the oil leak or spill

Report the oil leak or spill as required by regulations that apply depending on where you live. You can find the appropriate reporting or emergency contact information from your heating oil supplier, from your local building department, or from your local, state, or provincial department of environmental protection. Reporting oil spills or leaks within 24 hours is required by law in most jurisdictions.


Stop Deliveries of Heating Oil

Contact your heating oil delivery company for advice; do not continue to deliver oil to a leaking oil storage tank. It may be necessary to seal the oil delivery pipe, cap it, and place a DO NOT DELIVER OIL sign conspicuously on the oil delivery pipe and vent pipe as we have indeed had reports of oil deliveries to leaking, abandoned, and even disconnected oil filler pipes.

Soak up Spilled Heating Oil Indoors

  • For small heating oil spills use cat litter or bentonite clay to absorb liquid heating oil spills.
  • Larger indoor heating oil spills may require emergency or makeshift damming to try to contain the spill area using anything at hand: towels, sandbags, hoses, rags.
  • Your heating oil company will be able to provide additional cleaners and deodorants that can help reduce the odors from an indoor oil spill.

Environmental Issues & Regulations for Oil Tanks

In the U.S. and many other countries state DEP/DEC/DNR (Departments of Environmental Conservation or similar agencies) have programs for registering buried tanks at any site storing (typically) more than 1100 gallons of heating oil. Requirements for gas (auto fuel), or other fuels may be different.

Eventually this concern may spread to smaller residential tanks. The concern is for leaks which contaminate the environment. Tanks located where they may leak into a local waterway or into the water supply are a special environmental concerns. (C)trap DJ Friedman.
