The state Department of Environmental Protection has cited a Washington County gas compressor station for emitting black smoke during two days last month.
According to the Pittsburgh Post-Gazette, the pollution lead to numerous complaints from nearby residents:
The state Department of Environmental Resources cited MarkWest Liberty Midstream & Resources LLC for actions “inconsistent with good operating practices” that occurred July 14 and 15 at its plant along Route 519 in Chartiers Township, about three miles from Houston Borough…
In a prepared statement, MarkWest officials said the plant recently experienced several controlled flares at its so-called Houston facility associated with bringing new equipment online.
“As designed, our automated safety control system isolated and directed natural gas liquids to the facility’s flare while our operations personnel worked to make necessary adjustments,” it said. “Public safety was never at risk, and the safety equipment worked as designed.”
