Individuals and organizations intending to install underground fuel storage tanks shall comply with the following special installation and inspection requirements, in addition to the requirements contained in Article 79 of the Uniform Fire Code:

A. Prior to a fuel tank being installed in the ground, it must be approved by the city fire chief and the city’s chief building inspector or their designees while on-site and immediately prior to installation. This approval will require verification of the required coatings, approval tags and serial numbers and a complete visual inspection of the surface and/or surface coatings of the tank.

F. The location of all lines and/or tanks shall be “staked” by the installation contractor upon completion of all filling to provide all contractors sufficient guidance to avoid potential damage to the system(s) due to impact of heavy equipment, the driving of stakes, or similar occurrences.
