LICENSE C-lO 684718 CORROSION- ELECTRICAL SER VICES, INC. INTRODUCTION This report contains information pertinent to the successful operation of the cathodic protection system located at B.P. Circle Deli, 1416 Golden State Avenue, Bakersfield, California, including present and historical data, system specifications, survey procedures and recommended maintenance program. BACKGROUND The impressed current cathodic protection system installed at this facility in 1995 consists of the following items: Four 3-inch diameter x 60-inch long graphite anodes installed in two 12-inch diameter x 20-foot deep cathodic protection wells. The wells are backfilled with petroleum coke breeze and vented to the surface via PVC piping. A traffic-rated road-box is placed over each anode well. The anodes are connected to the rectifier by a header cable. · One Good-All rectifier rated at 50 volts and 12 Amperes (DC). · Miscellaneous electrical fittings and cathode header cable. SURVEY PROCEDURES The following procedures were followed during the annual survey: · The rectifier was inspected and the operating voltage and amperage were noted. Structure-to-soil potentials were measured with a digital voltmeter connected between the structure and a saturated copper-copper sulfate reference electrode in contact with the earth. Test point locations are listed on the attached data sheets. During the above procedure the tap settings on the rectifier were adjusted as needed to ensure that sufficient protective current is being applied to the underground metallic structures at this facility. 14020 MARYTON AVENUE, SANTA FE SPRINGS, CALIFORNL4 90670 PHONE: (562) 921-9522 FAX: (562) 921-6885 CA. LICENSE C-lO 684718 1 CORROSION- ELECTRICAL SER VICES, INC. SURVEY ANALYSIS Structure to soil potential measurements for each test point are above National Association of Corrosion Engineers (NACE) design criteria of 850 millivolts (mV) with cathodic protection applied. Rectifier output (DC volts and amperes) and potential measurement data for each test location are shown on the enclosed data sheets. CONCLUSIONS AND RECOMMENDATIONS Based upon our visual inspection and the data obtained during the survey, Corrosion- Electrical Services, Inc., concludes the following: · The cathodic protection system is operating as de'signed and the underground tanks and associated piping are receiving adequate protective currenL Corrosion-Electrical Services, Inc., recommends that the rectifier data (volts and amps) be recorded weekly on the attached Rectifier Data Sheet and mailed or faxed to Corrosion-Electrical Services, Inc., on a quarterly basis. If any significant changes are observed in the volts and/or amperes on the rectifier, Corrosion-Electrical Services, Inc., should be notified immediately. Along with the above Corrosion-Electrical Services, Inc., recommends, that in order to protect your investment, an annual survey be performed by a qualified individual. We will forward a letter approximately one year from this date requesting your authorization to perform this service on your behalf. 14020 MARYTON AVENUE, SANTA FE SPRINGS, CALIFORNIA 90670 PHONE: (562) 921-9522 FAX: (562) 921-6885 CA.
