Atlantic Coast Pipeline (ACP), a $7 billion, 600-mile pipeline that will stretch from West Virginia into North Carolina, is facing an existential threat by leftist environmentalists. The project is stalled waiting on an appeal before the U.S. Supreme Court, filed last week (see Atlantic Coast Pipe Officially Asks US Supreme Court to Hear Case). If you bother to search through Federal Energy Regulatory Commission (FERC) filings on the project, you’ll notice a number of protests filed by Big Green groups and their well-organized supporters. What you don’t see nearly as much are letters of support. We have one–a big one.
