Mountain Valley Pipeline Boost Gets Environmental Timeline Through November 2026
Published Date: 1/20/2026
Notice
Summary
Mountain Valley Pipeline wants to boost its natural gas flow by building new pipeline parts, helping deliver 600,000 dekatherms daily. The government is preparing an environmental check, with a report coming out August 7, 2026, and final decisions by November 5, 2026. This affects local communities, energy companies, and regulators, with a clear timeline to keep things moving smoothly and on budget.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 0 costs, 2 mixed.
Project Adds Large Pipeline Capacity Locally
The Mountain Valley Pipeline Boost Project would add about 600,000 dekatherms per day of natural gas capacity and would modify three existing compressor stations and build a new Swann compressor station. Specific additions include +23,470 hp at Bradshaw (Wetzel County, WV), +52,500 hp at Harris (Braxton County, WV), +52,880 hp at Stallworth (Fayette County, WV), and a new Swann CS with 136,900 hp in Montgomery County, VA.
Fixed EA and Decision Deadlines
FERC staff will issue an environmental assessment (EA) on August 7, 2026 with a 30-day comment period, and other federal and delegated state agencies must reach federal authorization decisions within 90 days of the EA—by November 5, 2026. The schedule formally sets the regulatory timeline that applies to agencies that issue permits and approvals for the project.
EA Will Address Local Environmental Concerns
FERC says the environmental assessment will address all substantive scoping comments, including concerns raised about groundwater, waterbodies, wildlife, traffic, air emissions, noise and vibration, compressor station siting alternatives, pipeline safety, human health, and climate change. The EA will be available for a 30-day public comment period after it is issued on August 7, 2026.
