What's the source of this waste? <br /> a. Rinsing chlorine cylinders <br /> 2. What's the volume of waste to be disposed of? <br /> a. when the procedure is changed its estimated to be as high as 40,000 gallons rinse <br /> water generated annually. <br /> b. Solids 1-2% of the volume <br /> 3. What's the chemical composition? Provide SDS/analytical data. <br /> a. Attached is the metals lab <br /> b. cylinders Rinse contains liquid and minor solids fraction. <br /> i. The leachate test (attached pdf) showed Cr/Cu/Pb/Ni above threshold. <br /> 1. When will this waste be discharged/disposed of? <br /> a. We have a pick up today <br /> 1. How often will this waste be discharged/disposed of? <br /> a. Based on volume estimates Liquid transfer to SLC would require —9 shipments per year. <br /> 1. If it'll be recycled, <br /> a. how will it be handled/ recycled? Depending on code review with your team- <br /> i. Treatment: <br /> 1. bag filtration <br /> 2. Ferrous treatment to remove Chrome, <br /> ii. The treated non-hazardous liquid fraction would be recycled into a <br /> process in Salt Lake facility. <br /> 1. Solids would be retained for disposal as Haz waste <br /> 2. Liquid would be recycled. <br /> a. Where would it be shipped? <br /> We would like to discuss 2 options, to be able to flex based on variation in rinse <br /> volume generation rate. <br /> i. Transfer to SLC for reclamation to allow liquid to be recycled, solids retain <br /> for disposal as hazardous waste. <br /> ii. during low volume generation periods, allow reclamation in Stockton to <br /> generate a non hazardous liquid for disposal and solids retain for disposal as <br /> hazardous waste. <br /> Garrett Backus,Ld.
