Please be informed that the RTC and other supporting documents pertaining to the above subject were sent <br />today via Fed Ex. Per your follow up inspection on 5/1/13 you have verified and cleared the items noted in the inspection <br />report except for the Diesel Line Leak detector" and the "Loss of Brine issue" Our contractor identified the issue in regards <br />with the brine, however the Diesel LLD still in progress as of this time. Please see my note below. <br />• (311) The Diesel line leak detector failed to detect a leak when tested. All line leak detectors shall be capable of <br />detecting a 3 gallon per hour leak at 10 psi. <br />o Status in progress. SSS will replace the Diesel turbine assembly, we have ordered the replacement turbine, <br />apparently the vendor (CPE) is currently waiting for the shipment/parts to come in. <br />• (403)A loss of Brine was found by the Designated Operator in the following list of sumps indicating a leak in the <br />annular space of the secondary containment. Brine was added to each sump annular space of the following days; <br />87 turbine sump (9/21/12, 11/17/12), UDC 7/8 (10/26/12), 91 fill sump (11/17/12), diesel STP (11/17/12), diesel fill <br />(11/17/12), vent sump (11/17/12), UDC 1/2 (1/23/13). <br />o On 5/14/13 the tank sumps were inspected and the sump annulars were found to not be vented properly, <br />trapping air in the annular and causing brine fluctuations. The sump vents were vented properly, then <br />vacuum tested — all 3 sumps (87 STP, 91 Fill & STP) passed. The brine levels were adjusted after removing <br />the trapped air. <br />I will keep you posted as soon as we received the parts for the diesel. <br />Also, I would like to take the time to thank you for your time and your attentiveness to our communications is exceedingly <br />appreciated. <br />Kind Regards, <br />Pauline <br />From: Garrett Backus [EH] [mailto:gbackus@sjcehd.com] <br />Sent: Wednesday, April 24, 2013 4:23 PM <br />To: Calalang, Pauline [CSI] <br />Subject: Chevron - 10858 Trinity Parkway Stockton - UST inspection report <br />Pauline, <br />Here is today's inspection UST report for Chevron at 10858 Trinity Parkway, Stockton. <br />Thank you, <br />Garrett Backus <br />Senior Registered Environmental Health Specialist <br />
