Additionally,the owner or operator must retest <br /> the UST system using ELD until the UST system is no <br /> longer leaking liquid or vapor. <br /> J <br /> PLEASE NOTE the difference between the terms"UST"and"UST System." UST means tanks and <br /> piping used for the storage of a hazardous substance[H&S Code, §25281(x)(1)].
