UST State Program Managers Respond to PEI UL 971 Survey

The PEI survey asked UST State Program Managers if their state will allow piping listed to the 1995 standard to be installed after the new UL 971 requirements became effective (July 1, 2021) and if their state has established a date after which all installations would be required to meet the new standards.

TULSA, OKLA. (PRWEB) August 25, 2021 -- The Petroleum Equipment Institute (PEI) recently surveyed the Underground Storage Tank (UST) State Program Managers to see how each state intends to handle "new" and "old" UL 971 listed pipe. The survey came about as a result of new requirements for Standard for Nonmetallic Underground Piping for Flammable Liquids, or Underwriters Laboratories (UL) Standard 971. The new standards are based on input UL received concerning improper piping system installations, inadequate piping system maintenance practices and failure to properly respond to leak detection alarms. These revised standards went into effect July 1, 2005.

UL 971 deals with underground piping for flammable liquids that is not made of metal. Nonmetallic underground pipe manufacturers have been meeting the requirements of the first edition of UL 971, dated October 30, 1995, in order to list their piping products as UL certified. To be considered UL listed, products manufactured on or after July 1, 2005, must now comply with the new standards.

Pipe manufactured to the 1995 standard that was produced prior to July 1, 2005, can and will carry the UL mark, since the UL mark on a product serves as the manufacturer’s declaration that the product complied with the UL requirements that were in effect at the time the product was produced.

The PEI survey asked UST State Program Managers if their state will allow piping listed to the 1995 standard to be installed after the new UL 971 requirements became effective (July 1, 2021) and if their state has established a date after which all installations would be required to meet the new standards. To date, 39 states have responded.

The results of this ongoing survey and a list of current UL 971 listed products can be found on the PEI web site at http://www.pei.org/UL971.
