C <br />2.8 Hazardous Characteristics of the Waste(s) that have been or will be Handled <br />The waste material observed to be handled by the tank system is used oil from vehicle <br />servicing. According to Mr. Mark Myers, the Store Manager, used oil is the only material the <br />tank received. <br />2.9 Initial Tank Installation Certification <br />Prior to placing a new tank system or component in use, an independent, qualified installation <br />inspector or an independent, qualified professional engineer (registered in California), either of <br />whom is trained and experienced in the proper installation of tank systems, shall inspect the <br />system or component for the presence of any of the following items and document in writing the <br />results of the inspection. <br />According to the attached email correspondence, the tank system manufacturer did not perform <br />an initial installation inspection or certification. The facility had no records documenting the <br />initial inspection and as of the date of this report, Apex was unable to identify any <br />documentation of an initial tank installation certification. <br />2.9.1 Weld Cracks or Breaks <br />No weld cracks or breaks were observed. <br />2.9.2 Scrapes of Protective Coatings <br />The protective enamel coating of the tank appears in overall fair to good condition with only <br />minor scraping and surface wearing observed. <br />2.9.3 Corrosion <br />No corrosion was observed at the visible side walls of the tank. Photographs taken of the <br />underside of the tank indicate that there may be some minor corrosion present. As such, Apex <br />recommends monitoring the tank for any spills that may occur from the underside. <br />2.9.4 Structural Damage or Inadequate Construction or Installation <br />Structural damage or inadequate construction or installation includes items such as cracks, <br />punctures, and damaged fittings. All discrepancies shall be documented and remedied before <br />the tank system is placed into use. <br />Above Ground Storage Tank Professional Engineer Certification Page 5 <br />
