As proposed, the Mountain Valley Pipeline (MVP) project is a natural gas pipeline system that spans approximately 303 miles from northwestern West Virginia to southern Virginia – and as an interstate pipeline will be regulated by the Federal Energy Regulatory Commission (FERC). The MVP will be constructed and owned by Mountain Valley Pipeline, LLC (Mountain Valley), which is a joint venture between EQM Midstream Partners, LP; NextEra Capital Holdings, Inc.; Con Edison Transmission, Inc.; WGL Midstream; and RGC Midstream, LLC.  EQM Midstream Partners will operate the pipeline and own a significant interest in the joint venture.

With a vast supply of natural gas from Marcellus and Utica shale production, the Mountain Valley Pipeline is expected to provide up to two million dekatherms per day (two billion cubic feet (Bcf) per day) of firm transmission capacity to markets in the Mid- and South Atlantic regions of the United States. The MVP will extend from the Equitrans transmission system in Wetzel County, West Virginia, to Transcontinental Gas Pipeline Company’s (Transco) Zone 5 compressor station 165 in Pittsylvania County, Virginia. As stated in the formal application, Mountain Valley Pipeline has secured firm commitments for the full capacity of the MVP project under 20-year contracts.

The pipeline will be governed by the United States Natural Gas Act, which requires a Certificate of Convenience and Necessity from the FERC before construction can commence. As currently planned, the pipeline will be up to 42 inches in diameter and will require approximately 50 feet of permanent easement (with up to 125 feet of temporary easement during construction).  As proposed, the project will require three compressor stations, with identified locations in Wetzel, Braxton, and Fayette counties of West Virginia.

Project Summary To-Date

On October 23, 2015, Mountain Valley filed a formal application with the FERC for approval to construct, own, and operate the Mountain Valley Pipeline. The application requesting the FERC Certificate of Public Convenience and Necessity was received and the MVP project was issued Docket Number CP16-10 on November 5, 2015. On September 16, 2016, the FERC issued the Draft Environmental Impact Statement (DEIS) for the MVP project and on October 13, 2016, the MVP project team filed an updated route with the FERC, known as the MVP October 2016 Proposed Route, which reflected numerous route adjustments to mitigate concerns raised during public comment periods.

On June 23, 2017, the FERC issued the Final Environmental Impact Statement (FEIS) for the MVP project. The FEIS considers and includes the analyzed data from civil and environmental surveys that have been conducted, as well as the comments, considerations, and concerns of landowners, community members, government agencies, and located elected officials along the proposed route.

On Friday, October 13, 2017, the FERC issued a Certificate of Public Convenience and Necessity for the Mountain Valley Pipeline (MVP) project. This Certificate follows more than three years of project planning, development, and review; and it recognizes the clear public need for this important energy infrastructure project. The MVP team has worked diligently with stakeholders, including landowners, community members, local officials, and state and federal agencies, to identify the best possible route for the proposed 303-mile underground pipeline. The Certificate comes after the FEIS, issued in June 2017, which concluded that adverse environmental impacts from construction/operation would be reduced to less-than-significant levels with the implementation of FERC-recommended mitigation measures. The FEIS also noted MVP’s adoption of hundreds of route adjustments, the majority of which were based on various landowner requests, avoidance of sensitive and/or cultural and historic resources, or engineering considerations.

MVP construction began in 2018 after the project secured each of its necessary permits and authorizations. By spring 2023, total project work for MVP was roughly 94 percent complete, which included all work on the project’s three compressor stations and its three original interconnect facilities, with the additional Greene interconnect mechanically complete, as well as roughly 282 miles of pipe welded and in-place, and more than half of the right-of-way fully restored.

Since the start of construction, industry opponents have continued to challenge MVP’s previously authorized and issued permits through ongoing litigation, placing their specific policy agendas above that of environmental protection and national energy security. These challenges have caused not only delays for the project, but more importantly have caused lengthier, unnecessary disruption for property owners along the route and inhibited MVP’s ability to complete the project and fully restore the right-of-way, which is the best method of environmental protection.

On May 3, 2022, Mountain Valley Pipeline, LLC adjusted its schedule and total project cost for the MVP project. The project team is targeting to complete the MVP by year-end 2023, at a total project cost of approximately $6.6 billion. Currently, MVP has all necessary permits with exception of those needed to cross waterbodies and wetlands. The project team is working collaboratively with federal and state authorities on a modified crossings approach, which would use a combination of trenchless and open-cut crossing methods.

As our nation addresses climate change, MVP will play an important role in our transition to a lower-carbon economy, and we are committed to satisfying all regulatory requirements and safely building and operating this important natural gas transmission pipeline.

Project Schedule



Designing the Route

Engineering aspects have included surveying and evaluating various routes to help determine a proposed route with the least overall impact to landowners, cultural and historic resources, and the environment.  During the Pre-Filing Review, which began in late October 2014, the MVP team started to conduct environmental surveys, hosted open houses, and participated in FERC scoping meetings, all in an effort to encourage open discussion with community members, landowners, and public agencies.  These public meetings generated valuable feedback that helped shape the current route, as proposed in the October 2015 filing.

The proposed MVP route has been carefully designed to utilize existing gas and electric transmission corridors when possible; to avoid sensitive or protected areas when feasible; and to limit surface disturbance and minimize the overall environmental footprint.  As part of MVP’s commitment to communities, the project team has considered thousands of miles of alternatives and variations to the proposed route in an effort to alleviate concerns posed by interested and informed stakeholders along the route.

Counties along the proposed MVP route include:

  • West Virginia: Braxton, Doddridge, Fayette, Greenbrier, Harrison, Lewis, Monroe, Nicholas, Summers,  Webster, and Wetzel
  • Virginia: Craig, Franklin, Giles, Montgomery, Pittsylvania, and Roanoke


Health, Safety, and Environment:

The Mountain Valley Pipeline project team respects the concerns and opinions of community members; we value each landowner’s property; and we certainly value the safety of our employees, contractors, and every single person that lives in these communities. We want to work with everyone in our Virginia and West Virginia communities to make sure we’re building this pipeline safely and responsibly, and that we’re doing so in a way that has minimal impacts on their land and their daily lives. 

According to the National Transportation Safety Board and the U.S. Department of Transportation, natural gas pipelines have the best safety record of any energy delivery system in the United States. Mountain Valley Pipeline takes tremendous precautions to ensure the long-term safety of our pipelines – and once the pipeline is operational, we will utilize sophisticated technology to monitor the pipeline, in real time, 24-hours-a-day and 7-days-a-week.

Perhaps most importantly, Mountain Valley believes safety is our number one priority – we have a steadfast commitment to environmental protection and will conduct our business operations in a sustainable and environmentally responsible manner at all times.
