Meanwhile, there are portions of the project in Pennsylvania that have already been approved by the PA’s Dept. of Environmental Protection. In a notice published in the June 16 Pennsylvania Bulletin, the DEP issued the project a Section 401 Water Quality Certification for work being done in Lancaster and Chester counties.
