CERTIFICATION OF 480-GALLON WASTE OIL TANK <br /> This certification has been prepared for the 480-gallon waste oil collection tank located at the Antonini <br /> Enterprises, LLC facility, 701 D'Arcy Parkway, Lathrop, California. The waste oil collection tank is an <br /> aboveground double-wall rectangular mild steel construction tank located within the Maintenance Shop <br /> Area. The tank is brand new and meets AFI standards for non-flammable liquids. It was installed when <br /> the facility was purchased in 2013. The tank is supported (raised off the slab by about '/2 inch) by <br /> rectangular steel tubing and is anchor bolted directly to the concrete slab of the Maintenance Shop floor. <br /> At the time of this certification, the tank materials were in good condition and are compatible with the <br /> waste oil that is being stored. The tank is vented and has a removable cap of the interstitial secondary <br /> containment allowing shop personnel to visually and physically inspect for breaches of the interior tank. <br /> Because this tank is brand new and has a competent secondary containment of known manufacture, this <br /> certification requires the tank owner(s) and/or operator(s) provide in-house inspections (each time the <br /> tank is emptied) to verify structural integrity and ensure the tank remains free of deterioration and <br /> corrosion. Inspections and reporting are discussed within the SPCC Plan. Records of the inspection shall <br /> be logged and retained by Antonini management for a period of at least three years. The inspections shall <br /> continue until such time the tank and secondary containment are replaced, a new certification is provided, <br /> or a revised SPCC Plan Is prepared for the facility. <br /> CERTIFICATION <br /> I hereby certify that I have personally evaluated the waste oil collection storage tank described above. The <br /> tank has a distinguishing API manufacture plate, and was observed by me to be made with competent <br /> workmanship and materials suitable for its current use. The tank showed no signs of leakage or <br /> deterioration at the time of the inspection. Being familiar with the provisions of 40 CFR part 112, attest <br /> that this Certification has been prepared in accordance with good engineering practices. <br /> Engineer: iS. a ess <br /> Signature: J <br /> Registration Number: C 53220 <br /> State: California <br /> Date: October 14, 2013 <br /> EAL <br /> zNa A <br /> C vt� <br /> q OF <br />
