Tank and Secondary Containment Assessment Irerracon <br /> Lustre-Cal Facility Lodi, CA <br /> April 22, 2019, Revised April 30, 2019 Terracon Project No. NA197014 <br /> r <br /> r <br /> T4 <br /> T3 <br /> Photo 4- Looking north at the three 230 gallon polyethylene pH mixing tanks (T3, T4 and T5). <br /> Visual Inspection Notes - During the time of inspection the tanks all contained liquid. Active <br /> processing was ongoing and waste water was being drained in to the capture tanks. It was <br /> being actively mixed and pumped during the visit. As waste water enters the system, the <br /> capture tanks fill up to a point of roughly 300 gallons or 90 percent capacity, at which point an <br /> automatic float pump is activated. This triggers the internal pump to begin sending the captured <br /> waste water to the pH mixing tanks where it is treated and then released to the City of Lodi, <br /> California sewer system. The capture tanks (T1 and T2)are only on during business hours and <br /> also have an alarm system to notify if they are not working. Further, if overflow is to occur into <br /> the secondary holding, a sump pump would be activated and the water would be removed and <br /> placed back into the system. T1 is the primary tank in use. T2 is only rarely used and acts as <br /> a back-up for times when more capacity is needed, and for future expansion or use change. <br /> O No visual leakage was observed from the openings or fittings around the tank. <br /> O The interior and exterior surfaces were clean and free of leakage. <br /> O The nozzles, piping, gauges, and valves were free of leakage and were in good <br /> condition. <br /> Responsive ■ Resourceful ■ Reliable <br />
