He stated that the hexach lorobenzene discharge in Dec 2009 was due to a dilution factor in the lab, similar to the benzidine discharges confirmed in March 2011. He stated that their lab had a dilution factor issue which forced the reporting limits up 40 times their normal values. because the reporting limit increased (to 400 ppb), they weren’t sure whether the discharges were 399 ppb or 0 ppb. Therefore they

reported the reporting limit to the state and included an explanation o their cover letter. Mr. Clark stated that h one - time increase was due to a laboratory error. I thanked Mr. Clark for his time and told him I ’d call back with any fur ther questions.
