Tank And Piping Installation

If you install an UST system after December 22, 1988, it must be properly installed according to a code of practice developed by a nationally recognized association or independent testing laboratory and according to the manufacturer’s instructions (40 CFR Part 280.20(d)).  Some states may require that UST installers be certified (in addition to being qualified) to conduct this type of work. You should check with your state or territorial UST program to be sure that you follow the appropriate regulations.

Installation includes excavation, tank system siting, burial depth, tank system assembly, backfilling around the tank system, and surface grading. Many mistakes can be made during installation. For example, mishandling of the tank during installation can cause structural failure of fiberglass-reinforced plastic tanks or damage to steel tank coatings and cathodic protection. Improper layout of piping runs, incomplete tightening of joints, inadequate cover pad construction, and construction accidents can lead to failure of piping.

You need to make sure that installers carefully follow the correct installation procedures called for by industry codes and follow manufacturer’s instructions.

In addition, federal regulations (40 CFR Part 280.20 (e)) require that owners and operators ensure one or more of the following methods of certification, testing, or inspection is used to demonstrate compliance with the installation requirements by providing a certification of compliance on the UST notification form (PDF) (5 pp, 102K, About PDF).
