RECEIVED <br /> AUG 2 &2016 <br /> ENVIRONMENTAL <br /> Item 504: CCR 66265.193 Hazardous waste tank system lacks secondary conlAW tDEPARTMENT <br /> Secondary containment was not provided for the 450 gallon tank. According Ryan Fane, P.E. <br /> this statement was made about the 1,750 gallon tank 'The pit used for secondary <br /> containment does not appear to meet the requirements of 22 CCR 66265.193 as it did not <br /> appear to be lined and cracks were observed in concrete above the liquid level in the pit at <br /> the time of inspection".Secondary containment shall be provided for tank systems to prevent <br /> the release of hazardous waste or hazardous constituents to the environment. Secondary <br /> containment shall be designed, installed, and operated to prevent any migration of wastes <br /> or accumulated liquid out of the system to the soil, ground water, or surface water at any <br /> time during the use of the tank system, and capable of detecting and collecting releases and <br /> accidental accumulated liquids until the collected material is removed. Immediately provide <br /> secondary containment <br /> which meetsthe requirements of Title 22 forthe 450 and 1,750gtanks. <br /> This is a Class I violation. <br /> Owens' Response/Corrective Action: <br /> The facility intends to provide secondary containment for the 1,750-gallon and <br /> 450-gallon waste oil tanks. The facility is evaluating the following options for <br /> correcting this item: retrofitting the existing tanks by placing a vessel inside the <br /> existing tank to be a new primary(and the existing tank would be the secondary <br /> containment), or replacing the tanks with double-walled tanks. <br /> Item 505: CCR 66265.194 Failed to maintain tanks for storage of incompatible materials or <br /> prevent spills and overfills. <br /> Staining was seen on the 450g tanks and 17SOg tanks and in the surrounding areas indicating <br /> an overfill or release. Appropriate controls and practices shall be used to prevent spills and <br /> overflows from the tank or secondary containment systems. These include at a minimum: <br /> - spill prevention controls (e.g., check valves,dry discount couplings); <br /> - overfill prevention controls (e.g.,level sensing devices, high level alarms, automatic feed <br /> cutoff,or bypass to a standby tank);and <br /> - maintenance of sufficient freeboard in uncovered tanks to prevent overtopping by wave <br /> or wind action or by precipitation. Uncovered tanks shall be operated to ensure at least 60 <br /> centimeters (2feet) of freeboard, unless the tank is equipped with a containment structure <br /> (eg., dike or trench), a drainage control system or a diversion structure (e.g., standby tank) <br /> with a capacity that equals or exceeds the volume of the top 60 centimeters (2 feet) of the <br /> tank. <br /> Immediately implement appropriate controls and practices to prevent spills and overflows <br /> from the tank or secondary containment systems. <br /> This is a Class Ilviolation. <br /> 11 <br />
