Small Heating Oil Tank Closure (Heating Oil Tanks less than 1,100 gallons not located at an Article XV Regulated Facility)

If you use fuel oil to heat and/or provide hot water to your home or business, you should consider the following facts:

  • Fuel oil contains chemicals that can pollute drinking water resources.
  • We know that the movement of groundwater is such that we are currently drinking water that was recharged into the ground many years ago.
  • Fuel oil that is leaking now may reach our drinking water wells in future years.
  • If your oil tank is 30 years old or older it may be about ready to fail.
