General Subject:
2009 DMR Hexachlorobenzene Discharges

                       TOPICS DISCUSSED AND ACTION TAKEN

On May 5, 2011 at 1pm I called Clean Harbors Baton Rouge and left a message for Billy Clark requesting confirmation on their 2009 DMR hexachlorobenzene discharges. He had confirmed the benzidine discharges in March 2011 and stated that there was a missing BDL indicator in those values. He also stated that the December 2009 values were higher than normal due to dilution factors. At 4:47pm, Mr. Clark returned my call and left a message. 

On May 9, 2011 at 10:50am, Mr. Clark returned my call and left a message. At 11:42am, I returned Mr. Clark's call and left a message. 

On May 12, 2011 at 2:50pm, I called Mr. Clark and left a message. At 4:00pm Mr. Clark returned my call. He stated that the hexachlorobenzene 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. Hexachlorobenzene discharges came back non detect but 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 of the high value in their cover letter.  Mr. Clark stated that hexachlorobenzene has always been non detect in this waste stream, this 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 further questions.
