AmokAE�M AW-1- Frain �111�'"Inow a %W t M1111111W To: Mr. Ray von Flue, E.H.S. From: John Lynch, Wright Environmenal Services, Inc. RE: 7373 West Lane, Stockton CA The memo dated December 9, 2002 from PHS-EHD noted certain deficiencies in Service Request No. 0032058 dated December 3, 2002 for repairs at Kaiser Permanente in Stockton (Operator) at the referenced address. The Service Request submitted was for the testing and repairs noted in that request During the testing covered by the original Service Request, additional repairs and improvements to the Backup Fuel Supply System were identified. Discussions with PHS-EHD resulted in Wright and PHS-EHD acknowledging that an amendment to the original Service Request was required to describe and incorporate the additional work into the Service Request previously submitted. Prior to the Service Request of 12-3-02, Wright had coordinated with Mr. Wilson at PHS-EHD to provide notice of SB -989 testing for the back up fuel system. Testing of the of the four existing fiberglass secondary containment piping runs resulted in three failing, and, one passing a 5 -psi test. Two existing black iron supply (safe suction) and two return lines between the tank piping sump and the transition fittings where the supply and return lines transition to above grade piping in the boiler and generators rooms were tested. Additional tests were initiated to attempt to isolate the leaks in containment piping. These tests did not isolate the leaking secondary containment piping. No leaks were observed in the primary supply and return lines and no diesel fuel was observed within the containment piping or piping sump. A copy of the secondary containment piping test and protocol is attached (Attachment 1). Tank Testing (Annular & Primary) Operator requested Wright to repair annular riser that had an improper coupling (rubber coupling) seven inches below test fitting within grade ring. This rubber coupling connected the steel riser from the tanks annular space to a PVC nipple that extended the annular space riser to within 4-inchs of grade for testing. Apparently when the operators testing firm tested the primary tank and the annular space the annular space vacuum test failed. The failure was attributed to the rubber coupling and Wright was then hired to make the repair under the original Service request submitted. After that repair to the annular space riser, Wright contracted with Afford -a -Test and the tanks primary and annular space passed testing. Copies of the Certification from Afford -a Test are attached for your records (Attachment 2). If an additional test is required, please advise so that this can be rescheduled with the certified tester.
