An affiliate of EdgeMarc Energy Holdings LLC has agreed to pay a $185,000 civil penalty to Pennsylvania for violating several state laws. The state Department of Environmental Protection (DEP) said that between 2014 and 2015 inspections of the Constellation Pipeline Project revealed that EM Energy Pipeline Pennsylvania LLC had harmed surface water and wetlands. This included failure to prevent accelerated erosion and sedimentation, and constructing an encroachment or water obstruction without a permit, among other things. DEP said EM Energy has since resolved all of the violations.
