Fwd: RE: Thule Towing Systems Page 5 of 7 <br /> were going to discuss the project <br /> with your supervisor and I was going <br /> to get you a more thorough <br /> description of the process(below) <br /> and a drawing(attached). <br /> Please give me a call and let's <br /> discuss at your earliest convenience. <br /> I am usually in from 8:30 am to 3:00 <br /> pm ... I expect that is exactly when <br /> you are OUT-but I hope we can <br /> connect. I will stay later than 3:00 if <br /> I know we can talk. <br /> Waste generating process: <br /> Our rinse stations in our washer <br /> area of the paint line are Stages <br /> (tanks)2, 4, S and 7; each rinse tank <br /> was tested separately. There are a <br /> total of 8 stages in the paint line and <br /> are as follows: <br /> Stage 1 is Potassium hydroxide for <br /> cleaning the oils and dirt off of the <br /> parts; it is a spray wash heated to <br /> 170 degrees and is changed out 3 to <br /> 4 times per year. It is pumped into <br /> totes than hauled offsite by <br /> Advanced Chemical Treatment. <br /> Stage 2 pre rinse I and post rinse 2 <br /> is a rinse tankf=lled with City- <br /> supplied water, the pre rinse and <br /> post rinse are spray washes that are <br /> supplied by the stage 2 spray wash <br /> pump and drain back into the tank. <br /> We change this tank out on a weekly <br /> basis and refill with City water. <br /> Stage 3 is a Citric Acid spray wash <br /> for removing scale and carbon from <br /> 11/3/2009 <br />
