Section 2: Waste Analysis Plan <br /> 2.1 Constituents & Characteristics . <br /> The rinse water and filter cake wastes have the potential to be contaminated with metals regulated <br /> by California [Title 22 CCR 66261.24(a)(2)(A)] and or exhibit the characteristic of corrosivity. <br /> [Attachment C—Safety Data Sheets for Plating Products] <br /> The pH of the rinse water is tested manually on-site prior to transferring to on-site treatment system <br /> (if the pH is 2, or less or 12.5, or more the rinse water will be sequestered and managed as a <br /> corrosive (D002) characteristic waste). Logs with the pH of the rinse water are maintained on-site <br /> for a minimum of three years. <br /> Water samples have been collected from the rinse tanks and filter cake and analyzed for California <br /> Regulated Metals(CAM-17),which are constituents of concern and authorized to be treated under <br /> the facility's permit. [Attachment D—Analytical Reports] <br /> 2.2 Test Methods <br /> The following table identifies the test methods used for the filter cake and aqueous waste analysis: <br /> Rinse Water CAM-17 Metals 3010A & 7470A (Mercury) <br /> Filter Cake CAM-17 Metals 6020 <br /> 2.3 Sample Collection Procedures <br /> Twice a month on the first Tuesday and third Thursday of every month precision enviro-tech <br /> comes to our facility to collect sample of our waste water. These samples are collected and tested <br /> independently by precision enviro-tech. They have a rotating schedule to test for certain <br /> constituents. These test results are given to us and we turn them in to the city of Stockton's water <br /> district <br /> Approximately twice/year or when deemed necessary the contents of the tanks are replaced and <br /> transferred to the 750-gallon storage tank. We then use flocculant, Clean& Clear to produce a pin <br /> floc stirring at 100 RPM and raise the pH to 9. The metal we normally have to remove, drops out <br /> of solution best at a pH of 9. The crystals at the bottom of the tank are then drained into a holding <br /> vessel. This is treated as hazardous waste and is disposed of by Shop Hazard solutions as a <br /> hazardous waste. <br /> Premier Finishing Waste Analysis Plan <br /> 2 <br />
