Harlan Road, Lathrop, on July 27 , 1992 and report the <br /> following: <br /> Pipe to soil reading: A reading of -1 . 1 volts taken on the <br /> tank indicates the sacrificial anodes are working properly <br /> and that the tank is receiving cathodic protection. <br /> Secondary piping: A visual inspection indicated that the 2" <br /> product line from the tank to the pump is installed inside a <br /> 4" fiberglass containment line and any leakage would drain <br /> back to the inspection and containment pit. <br /> A check of the space between the outer and inner tanks <br /> indicated no leakage <br /> , _ — _..r,. .__. , � -.-... t -e _- k s-�_ ,....,. .,.�- , <br /> Based onuthe above `findings "the tank and the "cathodic "system " <br /> are working properly and require no corrective measures at this <br /> time. <br /> If you have any questions, please do not hesitate to give us <br /> a call . <br /> Sincerely <br /> R-M-S PROFESSIONAL CONSULTANTS , INC . <br /> Robert M.
