LG 162-2 . 7 - <br /> satisfy <br /> 7 -satisfy the monitoring requirement in Section 25290 . 1 (d) . These components <br /> include , but are not limited to , riser piping and access points on top of the tank , <br /> which provide access to the primary containment of the tank and may be in <br /> contact with vapors of the stored product. <br /> The requirement for sumps and UDCs to have sensors is as follows . Sumps and <br /> UDCs installed and monitored in accordance with paragraph AJ , above , must <br /> have sensors that are capable of detecting liquid and vapor releases from the <br /> primary containment. No sensors are required for sumps and UDCs installed <br /> and monitored in accordance with paragraph A. ii , above . Sumps and UDCs <br /> installed and monitored in accordance with paragraph A. iii , above , are only <br /> required to have sensors that are capable of detecting liquid releases . <br /> C . For UST components monitored continuously using vacuum , pressure, or <br /> interstitial liquid level measurement methods , is additional testing or <br /> evaluation necessary? <br /> If the component's current listing includes approval for its use with continuous <br /> monitoring using vacuum , pressure , or interstitial liquid level measurement <br /> methods , no further testing or evaluation is necessary . However, if the <br /> component's current listing does not include approval of its use with continuous <br /> monitoring using vacuum , pressure , or interstitial liquid level measurements , <br /> additional testing or evaluation may be necessary . Owners and operators should <br /> ensure that UST components are approved for use with a continuous monitoring <br /> system using pressure , vacuum , or interstitial liquid level measurement methods <br /> consistent with the requirements outlined in Sections 2631 (b) and (d) , Title 23 , <br /> CCR , as applicable . <br /> D . For USTs installed on or after July 1 , 2004, is the annual line tightness test <br /> on pressurized piping required? <br /> No . For USTs installed on or after July 1 , 2004 , an annual line tightness test on <br /> the primary piping is not required . <br /> If you have questions regarding this document, please contact the UST Program at <br /> (916) 341 -5775 or via e-mail at ust_@waterboards . ca .gov. <br /> Sincerely, <br /> Original signed by <br /> Kevin Graves , P .
