The Mountain Valley Pipeline (MVP) is a proposed 303.5-mile interstate natural gas pipeline that would cross about 3.5 miles of the Jefferson National Forest (JNF), in Monroe County (West Virginia), Giles County (Virginia), and Montgomery County (Virginia) (Figure 1). The pipeline route crosses the Appalachian National Scenic Trail (ANST) and the Brush Mountain Inventoried Roadless Area. As proposed, the construction phase of the MVP will require use of about 83 acres of the JNF, and the operational phase will occupy about 42 acres (less than 0.1 percent) of the JNF. No new roads would be constructed on the JNF
