GENERAL SUBJECT : PCB concentrations reported to DMR in 2008 

 

TOPICS DISCUSSED AND ACTION TAKEN 

I called USEC PDGDP on Wednesday, March 17, 2010 to discuss DMR data with Brian Bell. I left a message 

with office personnel identifying myself and explaining the type of information I was looking for. She told me 

that she would leave my message with Chris Travis, but that he was out of the office until the week of March 

22. 

On Tuesday, March 23, 2010, Mr. Travis returned my phone call. I briefly described the 304(m) annual review 

and how we obtain DMR data; I then asked Mr. Travis about the PCB concentrations reported for Outfalls 002, 

011, and 012 reported to DMR in 2008. 

Mr. Travis stated that USEC operates all processes within the facility; however, the Department of Energy owns 

the land. He stated that 99 percent of PCB concentrations are non-detect, and that any reports are legacy 

contamination. Mr. Travis explained that the facility is located on about 500 acres of land with large switch 

yards. The outfalls discussed are located on these switch yards and any PCB concentrations picked up from 

these outfalls are not a result of the processes occurring in the facility. Mr. Travis stated that any discharges

specifically from USEC, where PCBs are detected, are treated by carbon filtration prior to discharge. 

Mr. Travis stated that USEC does not have a permit limit for PCBs. He stated that they monitor these outfalls

for PCBs once a month, by grab samples. I asked him if he could confirm the PCB concentrations that we have 

listed in the 2008 data. All data matched. He stated that the detection limit for PCBs is 0.17 μg/L, and that any 

months where a value is not reported was the result of a below detection limit result. 

I called Mr. Travis back on Thursday, March 25, 2010 at 8 am to follow-up with some of the information he 

provided during our previous conversation. I asked Mr. Travis to provide the description of Outfalls 002, 011, 

and 012. Mr. Travis stated that the facility is located on 500 acres of land and that these outfalls are storm water 

outfalls. He explained that once any process water (usually once-through cooling water) passes through the 

underground pipe system, it is discharged into these large ditch areas (about 40-50 acres), these ditches/creeks 

are Outfalls 002, 011, and 012. He stated that the sample point is usually somewhere in the ditch area. Mr. 

Travis also explained that these outfalls only discharge during a rain event. He stated that they are fitted with lift 

stations in order to help pump the storm water through the ditches. During a non-rain event, the water is 

recirculated and treated for chlorine, before being discharged again to Outfall 012 during a rain even. He stated 

that the flows for these outfalls highly depend on the amount of rainfall. Mr. Travis also explained that any

PCBs picked up from these outfalls are from soil mobilization. Mr. Travis again emphasized that any PCBs 

picked up by the facility are treated by carbon filtration before discharging to avoid any issues or future 

permitting requirements.
