Propane tanks, whether buried underground or located above ground, are inherently safe. In the unlikely event of a release, propane is not harmful to soil or water, plus there are strict controls and codes that govern a tank’s placement.

This fact sheet from the Propane Education & Research Council lays out all the pertinent points concerning underground propane tanks, including:

  • How underground tanks are protected from corrosion.
  • Codes that must be met for tank installations.
  • Ease of access for refueling.
  • The useful service life of a properly maintained tank.

Remember that the decision to place a tank above- or underground depends on project specifics, as well as local codes. Be sure to contact your local propane retailer to see what options are available to you.

More information on underground propane tanks is available through PERC’s free online continuing-education courses, available at the Propane Training Academy.
