A foamy substance noticed Monday in Buffalo Creek was accidentally
deposited in the water two months ago as part of a pipeline
installation.
MarkWest Energy Partners notified the state Department of Environmental
Protection March 4 that there was an "inadvertent return" of drilling
mud while it was installing the pipeline in Blaine Township.
MarkWest operates a natural gas processing plant on Route 519 near
Houston.
Kevin Sunday, a press officer with the DEP, said after the department
was notified it investigated the matter. He said MarkWest notified the
DEP again Monday when the matter resurfaced after fishermen in West
Virginia reported seeing something in the water.
"(MarkWest has) been forthcoming, and they're working with us," Sunday
said.
Rob McHale, manager of environmental regulatory affairs for MarkWest,
did not immediately return a telephone call seeking comment Wednesday.
Sunday said the company was installing the pipeline about 30 feet under
the creek when it had an "inadvertent return" of drilling mud, or clay,
and foaming agent. The portion of the creek is located off Route 231 in
the "Hewitt to Hoskins" portion of the pipeline.
Sunday said it is believed that the substance flowed downstream and
into some stream beds where recent rain activated it, causing the water
to become foamy and cloudy.
Kathy Cosco, a spokeswoman for the West Virginia DEP, said results of
test sampling were not yet completed by the department.
However, she said a test at the Wheeling wastewater treatment plant
indicated it was bentonite, which is used as a sealant in drilling mud.
K. Robert Fowler, director of the Emergency Management Agency for
Brooke County, W.Va., said initial tests revealed whatever the
substance was, it was not toxic.
