Mountain Valley PipelineRICHMOND, Va. (AP) – A state agency has informed the developers of two multi-billion dollar natural pipelines proposed in Virginia and West Virginia that their projects will have to meet specific environmental standards. Media outlets report the Department of Environmental Quality sent letters last week to Dominion Transmission Inc. and EQT, saying they will be required to meet certain erosion and sedimentation standards, if they build their pipelines. Dominion Transmission has proposed building the Atlantic Coast Pipeline, while EQT has proposed constructing the Mountain Valley Pipeline. DEQ spokesman Bill Hayden said Tuesday that their agency wants to make sure that appropriate steps are taken to protect the environment if the projects are built. Both proposed pipelines, which are pending approval by the Federal Energy Regulatory Commission, are facing opposition from dozens of organizations.
