Question # 144

144. A covered facility feeds 50,000 pounds of solvent containing 90 percent methyl isobutyl ketone (MIBK) (i.e., 45,000 pounds) into a recycling process that is 85 percent efficient. The facility distributes the recovered MIBK in commerce. Should the facility count 45,000 pounds of MIBK (i.e., the entire amount that was inserted into the process) towards the processing threshold?
Yes. The facility considers the entire amount (45,000 pounds of MIBK) entering the recovery system toward the processing threshold regardless of the recovery efficiency of the process.
