PEI RP1200-24

These recommended practices apply to facilities that are equipped with USTs used for the storage of motor fuels, jet fuels, distillate fuel oils, residual fuel oils, lubricants, petroleum solvents, oils and other
petroleum products.

These recommended practices apply to:
• USTs;
• connected underground piping;
• underground ancillary equipment and containment systems;
• equipment from the dispenser shear valve and below.

These recommended practices do not apply to:
• mobile tank fuel dispensing systems (e.g., truckmounted refuelers);
• aboveground storage tanks;
• tanks containing refrigerated liquids, liquefied petroleum gases, liquefied natural gases or compressed natural gases;
• dispensing equipment above the shear valve.

These recommended practices are not intended to address the design, installation or day-to-day operation of UST systems. Nonetheless, it is important to consider the design and operational characteristics of an underground tank system when specifying overfill prevention, release prevention and leak detection equipment.

The test methods in this recommended practice relative to integrity testing of spill buckets, containment sumps and secondary containment are based on current industry practices and are intended to demonstrate that a leak from the primary containment will be detected before it reaches the environment.

If an AHJ requires components to meet specific leak detection standards, follow the requirements in the AHJ’s regulation.

This document is not meant to provide interpretation of regulatory or legislative requirements related to UST systems.
