Dear SirorMadam: Gulfstream Natural Gas System, L.L.C. (Gulfstream) received the U.S. Environmental Protection Agency's (USEPA's) October 25,2011 information request seekingknowledge or experiences regarding migration ofPCBs through natural gas pipelines pursuantto the regulatory conditions for authorized use ofPCBs innatural gas pipeline systems provided in40 C.F.R. §761.30(i)(1)(iii)(C). The following is Gulfstream's response to the subject informationrequest. The Gulfstream pipeline system was placed into service in May 2002 with no known sources of PCBs at concentrations greater than 50 ppm within the company's natural gas transmission system; nor does Gulfstream receive gas orpipeline liquids from otherpipelines that contain PCBs at known concentrations greater than 50 ppm. It 

## should be noted thatthe Gulfstream pipeline manages natural gas pipeline liquids as part ofour routine operations and laboratory analyses for waste disposal profiling purposes was performed on six samples collected between 2005 and 2010 and showed that PCBs were not present in these liquids at a detection limit of 1 ppm. Accordingly, the provisions of40 C.F.R. §761.30(i)(1)(iii)(C) do not apply to Gulfstream. Should you require further information, please do not hesitate to contact me at (941) 723-7101. Sincerely,
