01.02 When are underground tanks preferred?

Underground tanks are preferred when the following conditions are important factors:

1. The use of aboveground tanks is restricted or prohibited by local fire code or zoning.
2. The space limitations of the site would not allow for the footprint and setbacks required for ASTs.
3. The facility owner / operator believes that the underground tanks are more secure against vandalism.
4. The visual / aesthetic / architectural aspects of the building require an underground tank.
5. Gravity overflow protection from generator day tanks is a critical concern.
6. Gravity filling of the tanks is a critical concern, based on local fuel supply availability.
7. Cold weather considerations are critical and heating of tanks and piping is undesirable.
