Mountain Valley Pipeline: Congressional
Authorization
Updated June 26, 2023
The Mountain Valley Pipeline (MVP) is a 303-mile natural gas transmission pipeline, currently under
construction, which would link natural gas fields in West Virginia to the existing Transco pipeline in
Virginia (Figure 1). Although the MVP is over 90% complete in terms of mileage, the project has faced
numerous permitting challenges in federal court. As a result, construction repeatedly has been suspended.
A separate pipeline, the proposed MVP Southgate Project—still in early development—would extend the
MVP into North Carolina. The MVP’s permitting challenges, as well as recently enacted legislation to
authorize its completion, are of continuing interest in Congress.

MVP Federal and State Permit Status
Like other large infrastructure projects, the MVP requires authorizations from a range of agencies under
various federal statutes. Key agency requirements, and their status, are summarized below.

• Federal Energy Regulatory Commission (FERC). Interstate natural gas pipelines like
the MVP require a certificate of public convenience and necessity from FERC pursuant to
the Natural Gas Act. FERC issued a certificate to the MVP in 2017, and has extended the
MVP’s construction deadline twice, most recently to October 2026.
• National Park Service (NPS). The MVP crosses NPS lands under the Blue Ridge
Parkway, so it requires an NPS right of way. The agency issued the right of way in 2017
and reissued it in 2020.
• U.S. Fish and Wildlife Service (FWS). Federal agencies approving certain parts of the
MVP must consult with FWS under the Endangered Species Act (ESA). A Biological
Opinion the FWS issued in 2020 was vacated and remanded by the U.S. Court of Appeals
for the Fourth Circuit in 2022. FWS issued a revised Biological Opinion on March 1,
2023.
• U.S. Army Corps of Engineers (Corps). The MVP requires a Corps permit under
Section 404 of the Clean Water Act (CWA) and Section 10 of the Rivers and Harbors Act
for its water crossings. The Corps first authorized the MVP by general permit, but the
Fourth Circuit rejected that option twice, in 2018 and 2020. The MVP therefore applied
for an individual permit in February 2021. The Corps issued the permit on June 23, 2023.
• U.S. Forest Service (FS) and Bureau of Land Management (BLM). The FS and BLM
must approve rights of way for the MVP to cross federal land under their jurisdiction. The
Fourth Circuit has twice vacated and remanded Forest Plans and associated BLM rights
of way for the MVP, in 2018 and 2022. FS and BLM issued new records of decision and
approved rights of way for MVP in May 2023.
In addition to federal agency authorizations, under CWA Section 401, the MVP must secure water quality
certification from the states. In 2021, Virginia granted its certification, which was subsequently upheld by
the Fourth Circuit. West Virginia also granted its certification in 2021, but that certification was vacated
by the Fourth Circuit in April 2023. West Virginia reissued its certification on June 8, 2023.
Legislation to Approve MVP
The MVP has been a controversial project since it was proposed, including in Congress. Opponents have
expressed concerns about the need for the pipeline, its potential environmental impacts, and its potential
safety risks, especially in minority and low-income communities (i.e., environmental justice). MVP’s
proponents cite its purported benefits to the economy (e.g., jobs and lower energy prices), natural gas
royalties, domestic gas supply reliability, and its potential role supplying gas exports to U.S. allies. The
Biden Administration also has supported the pipeline. On April 21, 2023, the Secretary of Energy wrote a
letter to FERC to “submit the view that the MVP project will enhance the Nation’s critical infrastructure
for energy and national security.”
In the face of ongoing permit litigation and agency reviews, several bills in the 118th Congress (S. 1399,
S. 1449, and H.R. 3500) have sought to approve completion of the MVP. On June 3, 2023, President
Biden signed the Fiscal Responsibility Act of 2023 (P.L. 118-5) which includes provisions to approve the
pipeline. Section 324 of the act finds that “the timely completion of construction and operation of the
Mountain Valley Pipeline is required in the national interest.” Under the act, “Congress ... ratifies and
approves all authorizations, permits, verifications, extensions, biological opinions, incidental take
statements, and any other approvals or orders issued pursuant to Federal law necessary for the
construction and initial operation at full capacity of the Mountain Valley Pipeline.” The act further directs
the relevant federal agencies “to continue to maintain” such authorizations and declares that “no court

shall have jurisdiction to review any action taken” by these agencies to approve the pipeline, effectively
shielding these actions from further litigation.
Following enactment of P.L. 118-5, on June 15, 2023, the MVP’s developer wrote to FERC requesting a
three-year “extension of time until June 18, 2026 to complete construction of the MVP Southgate
Project.” Because the act does not apply to Southgate, the project must continue through its own regular
permitting process, which also faces challenges, including North Carolina’s initial denial of a CWA
Section 401 water quality certification in 2020.
Although infrequent, direct congressional authorization of major infrastructure projects has occurred in
the past, notably under the Trans-Alaska Pipeline Authorization Act of 1973 (P.L. 93-153). However,
some in Congress continue to oppose completion of the MVP. A Senate amendment (S.Amdt. 101) to strip
the MVP approval language from P.L. 118-5 drew 30 yea votes. Some Members object to the act’s
perceived special treatment favoring the project outside the regular permitting process, the impact of its
construction on landowners, and its potential contribution to climate change, among other concerns.
Nonetheless, with its federal permitting issues resolved under P.L. 118-5, the MVP’s developer intends to
complete the pipeline by the end of 2023. As construction of the MVP continues, the status of the
pipeline, potential safety issues due to its construction pauses, and market demand for its associated
natural gas supplies may be oversight issues for Congress.
