Ine.RIS <br /> °'CCdATNG rY;-1 tat!b�llff+ <br /> Waste Ana9Vsis Plan for Aqueous Waste Containing Metals <br /> [22 CCR § 66265.131 <br /> The process rinse water is generated from rinsing parts after they have gone through a <br /> chemical conversion and cleaning baths. There are eight rinse water tanks on the plating line. <br /> Two tanks per day, Monday—Thursday, are emptied and transferred to the Solid Removal Tank <br /> to be treated by the addition of flocculant on order to precipitate out metals. <br /> Prior to transferring water from the rinse tanks it is tested with the use of pH paper to validate <br /> that the pH is above 2 and less than 12.51. Samples were collected from the rinse tanks <br /> (Tumbling Rinse, Hot Rinse, Stripper Rinse and Pressure Wash) on June 29th and analyzed for <br /> CAM 17 metals (contaminants of concern). Samples were analyzed by Precision Enviro-Tech, <br /> and results included on lab report 7070719-01-04. CAM 17 metal results were below the <br /> thresholds referenced in 22 CCR § 66261.24(a)(2)(A). <br /> 1 If the pH is 2 or less, or 12.5 or more it will not be transferred to the Solid Removal Tank, it will be transferred <br /> directly to drums or a tote and managed as a hazardous waste. <br />
