The Delaware Riverkeeper Network and scores of other environmental groups in 35 states are demanding a congressional investigation of the Federal Energy Regulatory Commission, alleging it abuses its power under the Natural Gas Act by stripping states and their residents of legal rights, ignoring federal mandates and inflicting environmental harm, all in the interest of the energy industry,

In a letter to Congress in which the network was joined by more than 180 organizations, Riverkeeper Maya van Rossum on Wednesday urged members of Congress to hold hearings to review FERC’s actions, reform the Natural Gas Act and delay advancement of the Energy Policy Modernization Act, which is intended to streamline the process for reviewing and approving energy infrastructure. The Leidy Southeast Pipeline is one of the natural gas projects mentioned in the letter.
