Weber Avenue. 3rd Floor <br /> Stockton, CA. 95202 <br /> Ph# 209-468-3420 <br /> Fax#209-468-3433 <br /> Dear Mr. Jackson, <br /> As you are aware, we discovered failures on the Generator Supply and Return Secondary <br /> Piping runs between the U.S.T. and steel pipe transition while performing the SB-989, <br /> secondary containment test on 12-02-2003. We suspect the failures to be; (1) <br /> Underground Generator supply, secondary pipe failure, (2) Aboveground Generator <br /> return, secondary pipe failure. <br /> We would like to propose the following: <br /> 1. Notify San Joaquin County Environmental Health Dept. at least 48 hrs. before <br /> commencing work. <br /> 2. Provide a Helium test (a non regulated test) on suspected leaking secondary <br /> pipe to assist with the isolation of fracture. <br /> 3. Isolate leaks by utilizing a helium detector during pressurized helium test. <br /> 4. Saw cut (under sidewalk area)if required! <br /> 5. Expose damaged "Ameron" underground secondary piping. <br /> 6. Notify San Joaquin Environmental Health Dept. to observe fracture before SAY u <br /> _m©yigg forward with repairs <br /> 7. Make necessary repairs as per Manufactures recommendations. <br /> 8. Repair the aboveground failure on the return secondary piping as per <br /> manufactures recommendations. <br /> - 9. Re-Test both Supply and Return secondary piping runs with 3 - 5 psi.. of <br /> �_ nitrogen and hold for 15 min. after. ompleting repairs. <br />
