Dennis Catanyag [EH] <br /> From: Mark Zollo[mzollo@lodi.gov] <br /> Sent: Friday, February 25, 2005 12:48 PM <br /> To: Dennis Catanyag [EH] <br /> Cc: Richard Prima; Dennis Callahan <br /> Subject: FW: City of Lodi, MSC, Additional Testing <br /> Dennis, <br /> We began the corrections at 1331 S. Ham Ln. this week. <br /> Mr. Bianchetti, the engineer/corrosion specialist, was mistaken in regard to the pump <br /> conduit connection for the 10,000 gallon unleaded tank. Mr. Bianchetti thought that the <br /> diesel tank pump, which tested well, was separated from the rigid electrical conduit by a <br /> length of vinyl flexible conduit, which isolated the tank's cathodic system from the <br /> electrical system. Mr. Bianchetti suggested changing the conduit on the unleaded tank to <br /> flex as well. However, the diesel tank conduit, which does appear to be flexible vinyl, <br /> is rigid conduit fashioned in a tight bend. This matches the engineered plans for the <br /> project. The City's Building Official reviewed the plans for the installation project and <br /> confirmed that the connection to the tank should be rigid conduit bonded/grounded back to <br /> the panel (Class 1, Division 2, if I recall correctly) . <br /> I sent Mr. Bianchetti an e-mail and fax requesting follow-up investigation (e-mail, <br /> below) . <br /> Mr. Bianchetti scheduled next Friday, 3/4/05, 9:00 a.m. , at 1331 S. Ham Lane, to <br /> investigate further and identify the problem and solution(s) . <br /> I should have the board for the waste oil tank installed by then, too. <br /> Mark Zollo <br /> Facilities Services Supervisor <br /> Public Works <br /> City of Lodi <br /> 221 W.

Consequently, isolating the unleaded pump head from <br /> the electrical ground/bus does not look like it will solve the tank's issue with cathodic <br /> protection. <br /> > The City would like you to perform the additional testing that you outlined for me <br /> during our conversation. Please let me know when you can perform this work (preferably <br /> ASAP) . <br /> > At that time, I would like to review the report format. <br /> 1 <br />
