The Department of Environmental Protection Wednesday approved a project that will allow Williams-Transco to replace a portion of its existing pipeline in East Brandywine and East Caln townships, Chester County.

The approvals include a National Pollutant Discharge Elimination System (NPDES) permit to address runoff during construction and a Chapter 105 Water Obstruction and Encroachment permit required for stream crossings.

“We are confident that this work can proceed safely and with careful regard for the environment and the community,” DEP Southeast Regional Director Cosmo Servidio said.

The approvals issued today will allow the company to use an open-trench method to replace the 30-inch pipeline crossing the East Branch of the Brandywine Creek and Ludwig’s Run with a 42-inch pipeline.

The amended water obstruction and encroachment permit is subject to 13 special conditions that protect the water quality and aquatic life of the streams and support recreational uses through trail signs and safe portage for boaters.

DEP conducted a public hearing about the company’s proposal for this project in August 2012, following an extended public comment period.
