Hwy 88, Lodi, Ca <br />The attached application is submitted to apply for a permit to perform repairs on the #1/2 UDC and Super <br />secondary pipe. The enclosed test results indicate the failures. <br />We feel the failures are probably under the #1/2 UDC as it is a shallow Environ pan. The secondary piping <br />under the USDC will have a rubber boot covering the primary flex and these have been subject to failure. <br />We plan to remove the concrete adjacent to the #1/2 UDC, expose the product line and air test the <br />secondary. If the boot is bad we will replace it and re -test the super secondary line. If the line will still not <br />hold air we will perform the same operation at the other dispenser. If the line will stili not pass the pressure <br />test we will expose the balance of the line and check for the failure with a soapy water solution. <br />All our work will be subject to your inspection prior to backfilling. <br />Once the inspection is passed we will replace the concrete at our work areas and place the system back into <br />operation. <br />We should not be excavating to native soil, just into the backfill material so I am unclear if soil sampling will <br />be required. <br />Thank you, <br />rk�Vendeiro <br />MVP Petroleum Engineering, Inc. <br />916-205-1537 <br />
