A group of environmental advocacy groups, including Earthjustice and the Eastern Environmental Law Center, filed a lawsuit October 15 in the U.S. District Court for the District of Columbia challenging the Interior Department’s decision to allow construction of an upgraded high-voltage transmission line. The line would run through three national parks in Pennsylvania and New Jersey. The groups argue that the National Parks Service failed to conduct an adequate environmental analysis, thus violating the National Parks Service Organic Act and the Wild and Scenic Rivers Act. The utilities planning to construct the transmission line contend that the line is necessary to meet growing energy demand in the Northeast.
