Use the following procedure to make this <br /> differentiation_ <br /> • Divide the quantity of each Category A waste stream by the total quantity of both <br /> Category A and B waste streams, and then multiply the result by 100 to get a <br /> percentage. (See Example 5-2) <br /> • If applicable, calculate this percentage for each source (or hazardous waste <br /> stream)that contributes to the influent to a single wastewater treatment unit. <br /> <t > <br /> 33 <br />
