Environmental Health Department <br />b. Secondary piping test for all pipe connected to the newly installed sumps: Soap test of all <br />piping and penetrations (product, vapor recovery, vent, and chase), and pressure test, in <br />accordance with manufacturer specifications. <br />c. Verification of secondary piping slope for all piping connected to the newly installed <br />sumps (product, vapor recovery, vent, and chase) at 1/8 inch per foot or greater, to a <br />containment sump with an audible and visual alarm. Piping slope must be adequate at <br />the start of this inspection, with all piping in its final position and ready to be backfilled <br />without adjustments per the manufacturer's installation instructions. <br />d. Verification of all pipe setbacks, cross -overs, and burial depth, in accordance with <br />manufacturer specifications, and verification of appropriate piping backfill. <br />e. Integrity testing of all newly installed sumps, in accordance with manufacturer <br />specifications. <br />f. Verification of brine type, and witnessing of initial brine addition in all brine -filled sumps <br />and/or UDCs. <br />g. Verification of leak monitoring continuity for all installed vacuum, pressure, or hydrostatic <br />(VPH) components, including piping, sumps, under dispenser containment sumps <br />(UDCs), and all chase lines. Continuity testing at end points of each vacuum zone and <br />each vacuum monitored sump must be verified independently in operating condition. <br />h. Verification of liquid and vapor tightness component installation (shroud boots and band <br />clamps for spill containers, appropriate rubber -type gasket or clamps on lids on all fill, <br />vent, and STP sumps, etc.). <br />i. Spill bucket test: Verify minimum 5 -gallon capacity. Pass a one hour hydrostatic test (or <br />equivalent). Verify proper drainage method. <br />j. Monitoring system functionality for all sensors inside the newly installed sumps: <br />Functionality of the monitoring system, including all liquid and vacuum sensors, must be <br />verified to ensure it meets the requirements of CCR Title 23 and California Health & <br />Safety Code (HSC) Chapter 6.7. <br />k. Verification of accurate vacuum zone programming, including monitored volumes. <br />I. Since concrete will be broken near the existing piping and tanks, a secondary <br />containment test must be performed on all existing piping and tanks once concrete is <br />poured, in accordance with the manufacturer's guidelines. <br />The facility cannot receive fuel in or operate the new 87, diesel, and biodiesel tanks prior to <br />the EHD inspection and approval. <br />The facility cannot operate any buried product piping connected to the existing tanks and <br />UDCs which is cut and reconnected, prior to the EHD inspection and approval. <br />4. Any individual installing underground storage systems or components must possess, or work <br />under the direct and personal supervision of an individual physically present at the work site at <br />all times while work is being performed who possesses, all of the following: <br />• One of several permissible valid, current contractor licenses issued by the Contractors <br />State License Board (CSLB) <br />• A current UST Installation/Retrofitting certificate issued by the International Code Council <br />(ICC) <br />• A valid, current certificate of training from the manufacturer(s) of the component(s) being <br />installed <br />2 of 4 <br />
