the treatment tank, but would be pumped directly into drums or totes and managed as a corrosive <br /> characteristic hazardous waste. <br /> The process tanks are typically never emptied, but rather replenished with de-ionized water and <br /> process chemicals. If for any reason the process tanks would have to be emptied, the tanks would <br /> be tested for pH. If the pH of the process tanks is greater than 2 or less than 12.5, the wastewater <br /> would then be pumped to the treatment tank in the same manner as the rinse tanks. If the pH of the <br /> wastewater in the process tanks is 2, or less or 12.5, or more, it would then be pumped directly <br /> into drums or totes and managed as a corrosive characteristic hazardous waste. <br /> 1.4 Pressure Washing Station <br /> Metal products are pressure washed outside the facility at the covered pressure washing station <br /> [Attachment G—Pressure Washing Station Diagram]. The pressure washing is done to remove <br /> any imperfections and does not utilize any chemicals. Rinse water from the pressure washing <br /> station is pumped into tank 410 on the chem line. When tank#10 reaches capacity it is then tested <br /> for pH, if the pH is more than 2 or less than 12.5, it is then pumped to the treatment tank. If the pH <br /> is 2 or less or 12.5 or more, it would then be pumped directly into drums or totes and managed as <br /> a corrosive characteristic hazardous waste. <br /> i <br /> i <br /> Premier Finishing PYaste Analysis Plan <br /> 3 <br />
