Road <br />T--acy, CA, 93202 <br />Dear,,N& NS, & Mr. Von Flue, <br />6 Lll*)Cs at this site required repairs in order to pass SB989. Wrecognize the use of <br />Parescalant 626 was a non -approved material to make such repairs. In an effort make <br />approved repairs and open the station for the owner as soon as possible we are submitting <br />the .,',� <br />.(,,flowing work. plan. <br />As you know 5 of the 6UTDC's will pass SB989 and I of them still fails. Our Plan is 85 <br />f0flows. <br />Pirst,. Blue Line Technologies has a UL listed and labeled "Pell ethariie'non-split <br />peno',tration that can be in3talled from the inside of the UDC with self tappiu.g screws. <br />TIe UL listing is enclosed and the, D & S Dragline certification to install the Blue Line is <br />enclosed. May we change our, original submittal for penetrations where needed to Blue <br />Line? <br />S,--cond. of the 5 UDCs that now pass SB989 one of three repairs has taken place. In <br />=,tairt UDC's adjusting and tightening the existing penetration, and/or test reducer sealed <br />the UDC. In. other cases tightening the steel conduit joints and/or replacing the inner seal <br />witli,n the conduit and within the UDC sealed the UDC. In other cases, the Parasealant <br />626 sealed the UDC. <br />Sincf;-, the use of Pexascalmt 626 is not an approved repair we propose that where- that is <br />the confirmed method that sealed the UDC, we replace the existing peneVaTi.qn, with the <br />Blue Line Technologies, non -split Pellethane pcnctratiQ.n., or test reduce. As for the UDC <br />that remains in a failed state we propose to dig around the outside of the LTE)C in order to <br />confirm where the UDC is failing. When we will make the T -ng to the <br />required repair according <br />information. submitted herein_ <br />If tW.s proposal meets with your approval, I will ask D & S DT--�gline to provide you with <br />a sump -by -sump report explaining what has been done to each and what 561 needs to be <br />
