The 600-mile Dominion Energy Atlantic Coast Pipeline (ACP) project has completed about 35 miles of the project and that’s it. Why? Lawsuits, brought by Big Green groups. The biggest challenge the project faces is a lawsuit that ruled ACP could not cross under the Appalachian Trail. Dominion appealed the decision to the U.S. Supreme Court where it now sits. By all accounts, the recent oral arguments before the Supremes went well for ACP (see Atlantic Coast Pipeline had Very Good Day in US Supreme Court). Although the Supreme Court case is the biggest obstacle, there are other, smaller cases ACP still must overcome.
