Tanks installed after December 22, 1988, 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 underground storage tank (UST) installers be certified (in addition to being qualified) to conduct this type of work. Check with the implementing agency to be sure that owners and operators 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.
Owners and operators 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 use one or more of the following methods of certification, testing, or inspection to demonstrate compliance with the installation requirements. They must also provide a certification of compliance on the UST notification form.
To demonstrate compliance with the installation requirements, certify that:
All new and replaced tanks and piping must meet the secondary containment requirements, including interstitial monitoring. The Environmental Protection Agency (EPA) considers piping replaced when 50 percent or more of the piping is removed and other piping is installed. In addition, new dispenser systems must have under-dispenser containment.
