The Federal Energy Regulatroy Commission (FERC) in a divided decision approved the Atlantic Coast and Mountain Valley natural gas pipelines.

The FERC certificates came with multiple conditions. Other necessary permits for both projects are still pending.

Both pipelines would start in West Virginia and would carry gas from the Appalachian basin to U.S. markets.

One of the three FERC commissioners, Cheryl LaFleur, dissented. She wrote that she couldn’t conclude either project was in the public interest, a determination she said was influenced by similarities in their routes, impact and timing.

The $3.5 billion, 303-mile Mountain Valley Pipeline would run south from northern West Virginia through the center of the state, cross into Virginia west of Roanoke and then cut southeast north of Danville. EQT Midstream Partners will operate the pipeline and own an interest in the project with other energy companies.

The 600-mile, approximately $5 billion Atlantic Coast Pipeline would start in north-central West Virginia, cross Virginia and traverse eastern North Carolina. Its lead developer is Dominion Energy, along with partners Duke Energy, Piedmont Natural Gas and Southern Company Gas.

The approvals mean the pipeline developers will have the authority to use eminent domain to acquire land if they can’t reach an agreement with a landowner.
