On February 19, 2021, the applicant voluntarily requested that the Corps administratively revoke the aforementioned NWP 12 verifications issued for the MVP Project. On March 2, 2021, the NWP 12 verifications for the MVP Project issued by Huntington and Pittsburgh Districts were revoked. On March 3, 2021, the NWP 12 verifications for the MVP Project issued by the Norfolk District were revoked.

DESCRIPTION OF THE PROPOSED WORK: The applicant has requested a DA permit from the Huntington District, the Pittsburgh District, and the Norfolk District for the permanent discharge of dredged and/or fill material into 1,198 linear feet of streams and 0.5 acre of wetlands, the temporary discharge into 38,332 linear feet of streams and 13.92 acres of wetlands, including the permanent conversion of 3.7 acres of forested and scrub-shrub wetlands to emergent wetlands and work in navigable waters of the United States, as described in Tables 1-3 of the DA permit application and below, associated with construction of the MVP Project within the Huntington, Norfolk and Pittsburgh District regulatory boundaries.

The applicant has requested a DA authorization for the following activities within the Huington District:

  • Temporary discharge of dredged and/or fill material into 4,966 linear feet (0.4033 acre) of ephemeral streams, 5,599 linear feet (0.6611 acre) of intermittent streams, 8,586 linear feet (3.0622 acres) of perennial streams, 7.9213 acres of palustrine emergent (PEM) wetlands and the permanent conversion of 0.3698 acre of palustrine scrub-shrub (PSS) wetlands and 1.2251 acres of palustrine-forested (PFO) wetlands;
  • Permanent discharge of dredged and/or fill material into 265 linear feet (0.0224 acre) of ephemeral streams, 296 linear feet (0.0360 acre) of intermittent streams, 363 linear feet (0.1209 acre) of perennial streams, 0.4374 acre of PEM wetlands, and 0.0084 acre of a single PSS wetland. The applicant indicates there would be no permanent discharge of dredged and/or fill material into PFO wetlands;
  • Permanent installation of pipelines via subterranean installation methods under three (3) waterways (the Elk River, the Gauley River, and the Greenbrier River) subject to regulation under Section 10. This proposed installation method would not result in a discharge of dredged and/or fill material into waters of the U.S. and is not subject to regulation under Section 404; and
  • The installation of temporary water withdrawal structures on the Elk River, the Gauley River, and the Greenbrier River subject to regulation under Section 10.

For regulated activities within the Huntington District, see Figure 1, Figures 3-1 thru 3-3, 3-6 thru 3-36, Figures 4-1 thru 4-32, 4-77 thru 4-79, 4-84 thru 4-90, 4-103, 4-107, 4-112 thru 525 Tables 2 and 3, and Attachments H-1 and H-2 of the DA permit application.

The applicant has requested a DA authorization for the following activities within the Norfolk District:

  • Temporary discharge of dredged and/or fill material into 3,966 linear feet (0.472 acre) of ephemeral streams, 6,383 linear feet (0.811 acre) of intermittent streams, 6,921 linear feet (2.266 acres) of perennial streams, 3.9550 acres of PEM wetlands, and the permanent conversion of 0.3698 acre of PSS wetlands and 1.2251 acres of PFO wetlands;
  • Permanent discharge of dredged and/or fill material into 45 linear feet (0.007 acre) of ephemeral streams, 65 linear feet (0.011 acre) of perennial streams, and 0.539 acre of PEM wetlands. The applicant indicates there would be no permanent discharge of dredged and/or fill material into PSS or PFO wetlands; and
  • Permanent installation of pipelines via subterranean installation methods under two (2) waterways (the Roanoke River and the Blackwater River), subject to regulation under Section 10. This proposed installation method would not result in a discharge of dredged and/or fill material into waters of the U.S. and is not subject to regulation under Section 404. 

For regulated activities within the Norfolk District, see Figure 3-2 thru 3-9, Figures 4-525 thru 4-786, Figure 5, and Tables 2 and 3 and Attachment H-3 of the DA permit application. 

The applicant has requested a DA authorization for the following activities within the Pittsburgh District:

  • Temporary discharge of dredged and/or fill material into 617 linear feet (0.046 acre) of ephemeral streams, 332 linear feet (0.045 acre) of intermittent streams, 1,007 linear feet (0.352 acre) of perennial streams, 2.043 acres of PEM wetlands and the permanent conversion of 0.1444 acre of PSS wetlands and 0.0110 acre of PFO wetlands; and  
  • Permanent discharge of dredged and/or fill material into 137 linear feet (0.009 acre) of ephemeral streams, 55 linear feet (0.037 acre) of perennial streams. The applicant indicates there would be no permanent discharge of dredged and/or fill material into wetlands within the Pittsburgh District.

For regulated activities within the Pittsburgh District see Figures 3-36 thru 54, Figures 4-30 thru 4-77, 4-80 thru 4-83, 4-87 thru 4-103, 4-107, 4-10 thru 4-117, Tables 2 and 3, and Attachments H1 and H2 of the DA permit application.

Construction of the proposed pipeline project would necessitate a 125-foot wide construction right-of-way with a narrower 50-foot permanent right-of-way. Construction of the pipeline across streams and wetland features subject to Section 404 regulation would include a narrower 75-foot construction right-of-way and include the excavation of a ditch across the features, the placement of the pipeline within the ditch, the burial of the pipeline with the excavated material, and the restoration of the area to approximate pre-construction elevations and contours. The proposed pipeline project would also include the use, upgrade, and/or construction of approximately 200 miles of access roads, and the use of temporary mats and span bridges for construction access. Additionally, the construction of the proposed pipeline project would necessitate ancillary facilities such as contractor yards for temporary construction offices, equipment staging, material storage, and parking.

In addition to delivering natural gas to the Transco interconnect (Milepost [MP] 303.9), the proposed MVP Project would also deliver gas to four (4) intermediate delivery points: WB Interconnect in Braxton County, West Virginia (MP 77.3); Greene Interconnect in Monroe County, West Virginia (MP 180.7); Roanoke Gas Lafayette Tap in Montgomery County, Virginia (MP 235.6); and the Roanoke Gas Franklin Tap in Franklin County, Virginia (MP 261.4).

Plans of the proposal may be viewed within the DA permit application (see Enclosure 1 and application Figures 1, 3, 4, Attachment H, and Attachment J). The public notice version of the DA permit application and appendices are available for public download as separate documents on the Huntington District’s Public Notice page at https://www.lrh.usace.army.mil/Missions/Regulatory/Public-Notices/ LRH-2015-592-GBR.

ALTERNATIVES ANALYSIS: The project does not require access or proximity to or siting within special aquatic sites to fulfill its basic purpose and is considered a non-water dependent activity. The Section 404(b)(1) Guidelines state for non-water dependent activities, practicable alternatives that do not involve special aquatic sites are presumed to be available, unless clearly demonstrated otherwise. The applicant is required to provide an alternatives analysis that must overcome this presumption prior to receiving authorization for the discharge of dredged and/or fill material. The applicant has developed a variety of alternatives (preferred, alternative routes, alternative natural gas transportation methods, alternative pipeline systems, and no-impact) analyzing how the applicant’s project, as the discharge of dredged and/or fill material into streams and wetlands, could be conducted in order to avoid and minimize impacts to aquatic resources. The alternative must fulfill the overall project purpose as defined by the Corps. No permit will be issued until our office determines practicable upland alternatives are not available to achieve the overall project purpose informed by the applicant’s alternatives analysis.

AVOIDANCE AND MINIMIZATION: In evaluating a project area containing waters of the United States, consideration must be given to avoiding impacts on these sites. If waters of the United States cannot be avoided, then impacts must be minimized. Approximately 109,434 linear feet of streams, consisting of 30,592 linear feet of ephemeral streams, 36,704 linear feet of intermittent streams, and 42,138 linear feet of perennial streams and 34.021 acres of wetland, consisting of 49.16 acres of PEM wetlands, 3.96 acres of PSS wetlands, and 5.40 acres of PFO wetlands, are located within the proposed project area. The applicant has proposed to avoid approximately 69,831 linear feet of streams and 15.89 acres of wetland. See tables 2, 3, 4, 5, 19, and 20 of the DA permit application for further details. The applicant has indicated that there is no practicable alternative for the proposed project that completely avoids the discharge of dredged and/or fill material into waters of the United States and work in and under navigable waters of the United States (i.e. Elk River, Gauley River, Greenbrier River, Roanoke River, and Blackwater River) and would meet the overall project purpose. Avoidance and minimization efforts were incorporated into the proposal to reduce the discharges of dredged and/or fill material into waters of the United States and regulated activities in and under navigable waters of the United States, and to reduce the width of the construction right-of-way at stream and wetland crossings. A full description of the applicant’s avoidance and minimization efforts can be reviewed in Section 5 of the DA permit application and Section 4.3 Water Resources of the FEIS.

All pipeline project construction activities would adhere to the FERC’s Upland Erosion Control, Revegetation, and Maintenance Plan and state-specific equirements for pipeline construction in West Virginia and Virginia, as applicable. In West Virginia, the project’s stormwater discharges are regulated by a Water Pollution Control Act Permit for Construction authorization and sitespecific Erosion and Sediment Control Plans approved by the West Virginia Department of Environmental Protection (WVDEP). In Virginia, project construction must comply with Annual Standards and Specifications, site-specific Erosion and Sediment Control Plans, and sitespecific post-construction stormwater management plans approved by the Virginia Department of Environmental Quality (VADEQ). Timely construction and maintenance of sediment control measures as well as the restoration and revegetation of disturbed areas would minimize downstream sediment impacts. After construction, any temporary fill material would be removed in its entirety and the affected areas returned to approximate pre-construction elevations and conditions and revegetated, as appropriate. The applicant’s full discussion of avoidance and minimization are available for review in Section 5 of the DA permit application available on our website at https://www.lrh.usace.army.mil/Missions/Regulatory/Public-Notices/LRH-2015-592-GBR

COMPENSATORY MITIGATION PLAN (CMP): To compensate for the permanent discharge of dredged and/or fill material into 1,116 linear feet of streams and 3.5958 acres of wetlands in West Virginia, based on calculations using the West Virginia Stream and Wetland Valuation Metric Version 2.1 (WV SWVM), the applicant proposes to purchase 691 stream credits and 2.1961 wetland credits from approved mitigation banks. To compensate for the permanent discharge of dredged and/or fill material into 110 linear feet of streams and 1.3997 acres of wetlands in Virginia, based on calculations using the Unified Stream Methodology (USM) and a 1:1 credit ratio, as applicable, the applicant proposes to purchase 94 stream credits and 1.3997 wetland credits from approved mitigation banks. The applicant’s proposed compensatory mitigation plan is described in Section 5 and Tables 17 and 18 of the DA permit application available on our website at https://www.lrh.usace.army.mil/Missions/Regulatory/Public-Notices/ LRH-2015-592-GBR

The applicant’s CMP is currently under review. As part of our evaluation, the Corps will review the applicant’s WV SWVM and USM calculation sheets for accuracy. The proposed compensatory mitigation proposal is open to comment and is subject to change based on comments received. After review of all the submitted information, the Corps will make a determination of appropriate compensatory mitigation, in the event a decision is made to issue a DA permit.

WATER QUALITY CERTIFICATION (WQC): An individual Clean Water Act Section 401 WQC is required for this project from the States of West Virginia and Virginia assuring that applicable laws and regulations pertaining to water quality are not violated. It is the applicant's responsibility to obtain an individual Clean Water Act Section 401 WQC or a waiver from the WVDEP and the VADEQ. A DA permit, if otherwise warranted, would not be issued for this project until the Section 401 WQCs have been issued or waived and the 401(a)(2) processes, if required, as described in the “Clean Water Act Section 401 Certification Rule” (Rule, 85 Federal Register 42,210 [July 13, 2020]) have been completed in each state.

HISTORIC AND CULTURAL RESOURCES: The FERC is the designated lead federal agency and coordinator of all federal authorizations and consultation efforts pursuant to Section 106 of the National Historic Preservation Act (NHPA), including coordination with the appropriate State Historic Preservation Offices (SHPO), Tribal Historic Preservation Offices or other representatives, and the Advisory Council on Historic Preservation (ACHP).

On October 19, 2017, the FERC provided a letter to the ACHP that the MVP would have “an adverse effect on historic properties.” The letter indicated that the ACHP had suggested the development of a “Programmatic Agreement (PA), under Part 800.14.b, to resolve adverse effects for this Project as a whole.” The letter included supporting documentation regarding the FERC’s adverse effect finding. On September 8, 2020, the FERC, via e-mail, indicated that compliance with Section 106 of the NHPA was completed and the PA for the Mountain Valley Mainline Pipeline was executed on December 15, 2017. As stated in the regulations for implementing Section 106 – at Part 800.14b2iii – a PA is in effect and executed when signed by the FERC, the SHPO, and the ACHP. The execution of the PA completed the process of compliance with Section 106 of the NHPA.

A copy of this Public Notice will be furnished to the West Virginia SHPO and the Virginia SHPO for their review.

THREATENED AND ENDANGERED SPECIES: The FERC is the lead federal agency for Section 7 of the Endangered Species Act (ESA) consultation and has jurisdiction and control over the entire pipeline corridor. The United States Fish and Wildlife Service (USFWS) evaluated the entirety of the MVP Project. The Corps has reviewed the Biological Opinion (BO) issued on September 4, 2020 by the USFWS and has determined that it is inclusive of the Corps’ area of responsibility and is sufficient to address the Corps’ ESA action area.
