The Petroleum Equipment Institute (PEI) endorse or recommend particular materials , equipment, <br /> has produced this document as an industry service. It has suppliers or manufacturers ; <br /> been prepared in response to requests from underground discourage the development or installation of new <br /> storage tank (UST) system operators , tank testers and equipment or overfill . prevention and leak detection <br /> regulators for a single authoritative source of informa- devices ; <br /> tion . <br /> • discourage the development of new or improved <br /> The recommended practices described herein represent testing procedures and equipment. <br /> a synthesis of industry procedures and manufacturers' <br /> recommendations relating to spill, overfill; leak detection 1.4 Scope. These recommended practices apply to <br /> and secondary containment equipment.

Spill, overfill, leak detection and aboveground storage tanks ; <br /> secondary containment equipment is currently employed tanks containing refrigerated liquids , liquefied <br /> at UST facilities as required by local, state and federal petroleum gases, liquefied natural gases or compressed <br /> regulations. For this equipment to be operated effectively natural gases ; <br /> and safely, it must be maintained, inspected and tested for <br /> • dispensing equipment above the shear valve. <br /> proper operation on an ongoing basis . <br /> These recommended practices are not intended to address <br /> 1.3 Purpose. The purpose of this document is to <br /> provide a concise summary of general guidelines for the design, installation or day-to- day operation of UST <br />� systems . Nonetheless, it is important to consider the <br /> the inspection and testing of spill, overfill, leak deter- design and operational characteristics of an underground <br /> tion, secondary containment equipment, shear valves tank system when specifying overfill prevention, release <br /> and emergency stops at UST facilities .
