SECTION 165:25-2-134. Requirements for returning to service/use

  When an underground storage tank system is returned to service/use a tank tightness test, line tightness test, and a leak detector test must be performed by a certified tester, and must be completed on the underground portion of temporarily closed systems prior to returning the system to service if it has been out of service/use for more than twelve (12) months. Any system failure will require either closure or upgrade of the failed portion. Additional testing shall be required on any portion of the tank system considered detrimental to release detection depending upon the type of tank system installed. Notify PSTD on the prescribed "Return to Service" form when returning a system to service/use along with copies of all testing and the tank registration fees.
