Heating Oil Tanks

Tanks used for the storage of heating oil for consumptive use on the premises where stored are excluded from State regulations.  However, if the underground heating oil tank is also used for emergency generators, in this case the underground heating oil tank is a regulated tank.  Contamination related to the heating oil tank is regulated under the spill and should be reported immediately to DENR, Ground Water Quality Program, Phone (605) 773-3296

 

What to watch for:

 

Any spill over 25 gallons is reportable to DENR.  A spill is likely if: 

  • There is contaminated soil in the tank basin, pooled oil, sheen on surface water, or other visible signs;
  • Groundwater is contaminated (often detected by unusual taste, odor, or sheen); or
  • There has been a complaint to DENR indicating that a spill is causing a nuisance or other concern.

 

Also help protect the environment by the following:

 

  • If the supplier spills fuel while filling the tank, call them immediately to clean up their spill.
  • Watch your fuel consumption. If it is unusually high, this may indicate a leak or other problem needing attention.
  • Pay attention to any fuel odors, stains, or sheen around your fuel tank or furnace room.  They may indicate a problem that should be fixed immediately. Don’t let a small problem turn into a big one.

 

And check with your local city or fire official:
