Mountain Valley Pipeline: Congressional
Authorization
Updated July 12, 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). The project has faced numerous permitting challenges in federal court, which has
repeatedly caused construction to be suspended. A separate pipeline, the MVP Southgate Project—still in
development—would extend the MVP into North Carolina. The MVP’s permitting challenges, as well as
recent 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
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 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 requires 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. 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 economic benefits (e.g., jobs and lower energy prices), natural gas royalties, gas supply
reliability, and its potential role supplying gas exports to U.S. allies. The Biden Administration also has
supported the pipeline.
In the face of ongoing permit litigation and agency reviews, 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 language to approve the pipeline.
Section 324 finds that “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, seeking to shield these actions from further litigation.
The act also gives the U.S. Court of Appeals for the District of Columbia Circuit “original and exclusive
jurisdiction over any claim alleging the invalidity” of Section 324. Notwithstanding these judicial
provisions, on July 10, 2023, the Fourth Circuit granted a motion to stop construction of MVP through the

Jefferson National Forest while it considers the constitutionality of the act. On July 11, 2023, the Fourth
Circuit also granted a motion to stay the FWS Biological Opinion.
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
before, 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. 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,
given the MVP’s permitting provisions in P.L. 118-5, the pipeline’s developer intends to complete
construction by the end of 2023. As development of the MVP continues, the status of the pipeline,
potential safety issues due to its construction pauses, market demand for its associated natural gas
supplies, and the ongoing Fourth Circuit litigation may be oversight issues for Congress.
