Airport Way, Stockton - Install Repairs <br /> Hey Stacy! <br /> I want to thank you and your team for the call yesterday. We have started an internal review <br /> based on your concerns and frustrations so that this does not occur again. <br /> I have put the extra testing requests below with comments about what we discussed or what I <br /> will provide as a substitution. <br /> 1. Primary tank test of all three tanks in the split tank, in accordance with manufacturer <br /> specifications. — No concern from Xerxes <br /> 2. Secondary containment tank test of the split tank (interstice testing), in accordance with <br /> manufacturer specifications, prior to brine filling. — Please see attached Truchek documents <br /> as proposed substitution testing. <br /> 3. Confirmation of interstice continuity for all three compartments in the split tank. — Prior to <br /> Truchek Testing, Xerxes will install a small diameter riser in an end tank sump (see tank dwg <br /> 669-665 attached for proposed sump). Based on the tank layout, pIs advise if you would like <br /> to test the other shell or compartment. <br /> 4. Secondary piping test: Pressure testing of all piping (product, vapor recovery, vent, and <br /> chase), in accordance with manufacturer specifications. — Done by Petroleum Contractor <br /> 5. Integrity testing of all tank top sumps, in accordance with manufacturer specifications. — Done <br /> by Petroleum Contractor <br /> 6. Verification of brine type and witnessing of brine addition in the split tank and tank top sumps. <br /> — Removed original brine stored and re-used. Topped up with Xerxes factory supplied. Xerxes <br /> can provide a letter or proof of shipping. <br /> Also, I have attached a site plan with the compartments identified. <br />
