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.

Our fact sheet contains details on the many benefits of underground propane tanks. Additionally, the Propane Education & Research Council lays out all the pertinent points concerning underground propane tanks, including:

  • How underground propane tanks are protected from corrosion.
  • Codes that must be met for underground propane tank installations.
  • Ease of access for underground propane 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 find a local propane supplier using our locator tool and talk with them about the options available in your specific area.

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