PEI’s Recommended Practices for Installation of Underground Liquid Storage Systems provides the most current information on sound engineering and construction practices with regard to the proper installation of underground liquid storage systems.

The recommended practice is truly an industry document, as oil company engineers, trade associations, environmental regulators, equipment manufacturers, installation contractors, etc., have had an opportunity to review and comment on the revisions.

Key changes in the 2020 version include:

  • Revision of Section 10.13 to remove the recommendation to use metallic risers.
  • A new recommendation that installers should confirm riser pipe is compatible with the product transferred/stored and approved for use by the authority having jurisdiction.
  • A warning to use proper grounding techniques to dissipate static charge accumulation if a nonconductive riser pipe is installed.
  • A note recommending the use of drop tubes to reduce turbulence and vapor buildup during fuel deliveries.

The document contains sections on excavating, backfilling, anchoring, piping, release detection, cathodic protection, secondary containment and other aspects of tank system installation. There are three appendices as well. One contains formulas for calculating weight required to prevent tank floatout. Another describes procedures for calculating sacrificial anode requirements. The third contains a current publication reference of other tank installation documents. The manual, which contains 33 line drawings, is completely indexed.
