Fixed Treatment Unit Closure Plan <br /> Lika California <br /> A Division of Viktron w <br /> A. Introduction <br /> The following is a brief description of the procedure to be followed in the event of the closure of the fixed treatment unit on <br /> site. <br /> All waste remaining on site in tanks or drums will be treated on site if possible, otherwise it Nvill be shipped offsite <br /> for appropriate disposal. All empty containers will be triple rinsed, if they are acceptably,decontaminated they will be sent for <br /> drum recycling. Those drums that are unable to be recycled will be shipped to Chemical Waste Management Inc. as <br /> hazardous waste for appropriate disposal. All equipment and plumbing will be decontaminated if possible. Otherwise these <br /> materials will be shipped to Chemical Waste Management Inc. as hazardous waste for appropriate disposal. All floors and <br /> trenches in the treatment system will be cleaned with a high pressure washer and the water treated through the treatment <br /> system. All tanks in the treatment system will be cleaned with a high pressure washer and the water treated on site. The <br /> water remaining in the last few tanks, that is not able to be treated, will be drummed and shipped off site. <br /> B. Maximum Inventory Estimates <br /> 1. Estimate of maximum waste inventory <br /> a. Maximum hazardous waste in containers= 171,550 lb. <br /> b. Maximum hazardous waste in tanks=534,500 lb. <br /> 2. Estimate of waste that will be generated from closure activities <br /> a. Containers and container areas=249,000 lb. <br /> b.Tanks and tank areas=398,000 lb. <br /> c. Other(Trenches,Floors)=98,000 lb. <br /> C. Waste Removal/Treatment and Decontamination Procedures <br /> After final manufacturing facility shut down all waste removal, equipment decontamination, and manufacturing <br /> facility will be performed. All waste generated from this procedure will be transferred to our waste treatment system. All <br /> batch processing will be performed using current methods and procedures and all empty containers triple rinsed. The waste <br /> materials will be removed from the batch processing tanks and the tanks decontaminated. Upon completion of the <br /> decontamination the batch processing tanks will be removed. At this time the container storage area and the batch processing <br /> areas will be decontaminated. Following this decontamination all of the plumbing will be removed from the trenches and the <br /> trenches decontaminated. All waste water generated from the above decontamination will be treated through our continuos <br /> flow waste water treatment system. <br /> At this point the continuous flow waste water treatment system will be dismantled. Each of the tanks will be <br /> emptied into the next step of the treatment process. The tanks will be decontaminated with a high pressure washer and the <br /> water generated by this will be emptied in to the next step of the treatment process. As each is removed the area that was <br /> around and beneath it will be decontaminated. This process will continue up to the clarifier. At this point a vacuum truck <br /> will be used to remove all material remaining in the clarifier and all materials generated during decontamination. <br /> There will be 2 tanks remaining at this point. They,will be tank T7 and the sampling tank. The pH in T7 will be <br /> within an acceptable range and pump to the sampling tank and the tank removed. Any material remaining in the sampling <br /> tank will be pumped to the sanitary sewer and the tank removed. Any water generated from the decontamination of this area <br /> will be removed by the vacuum truck. This should complete the waste removal and decontamination of the fixed treatment <br /> unit. <br /> 1 <br />
