Recommended Practices & Exams

PEI began publishing technical manuals in 1986 with the introduction of Recommended Practices for Installation of Underground Liquid Storage Systems, PEI/RP100. Since then, the association has written several additional manuals and developed online tests for each document.

These heavily researched, peer-reviewed technical documents address the biggest operational issues facing the industry. Recommended practices and procedures are reviewed and revised on a regular basis to reflect the latest technologies and industry trends.

The manuals are used by industry regulators, fire marshals and code officials, as well as industry-related associations. The manuals are available for purchase by anyone with an interest in the petroleum equipment and liquid-handling industry.
