DEPARTMENT OF THE ARMY CORPS OF ENGINEERS PITTSBURGH DISTRICT 1000 LIBERTY AVENUE PITTSBURGH PA 15222-4186 REPLY TO ATTENTION OF October 19, 2018 Regulatory Division LRP-2015-798 Mr. Robert Cooper Mountain Valley Pipeline, LLC 2200 Rice Drive, Suite 200 Canonsburg, PA 15317 Dear Mr. Cooper: I refer to your project to construct a natural gas pipeline that is 303 miles in length and 42 inches in diameter, known as the Mountain Valley Pipeline (MVP). This letter pertains specifically to the 32 miles of the proposed pipeline and 15 miles of proposed access roads located within the United States Army Corps of Engineers’ (Corps) Pittsburgh District’s (LRP) area of regulatory responsibility. Please reference the December 19, 2017, and May 18, 2018 Nationwide Permit (NWP) verification letters, project number LRP-2015-798, issued to you authorizing your project under NWP No. 12 (Utility Line Activities). Impacts to waters of the United States associated with LRP’s portion of the MVP are 59 separate stream crossings and 62 separate wetland crossings. These impacts are located within Wetzel and Harrison Counties, West Virginia. As you are aware, on October 2, 2018, the United States Court of Appeals for the Fourth Circuit vacated the Corps’ verification of MVP’s compliance with NWP 12 within the Corps’ Huntington District (LRH). In view of the Court’s order vacating the LRH verifications, on October 5, 2018, the Corps’ Norfolk District exercised its authority under 33 CFR 330.5 and suspended its verification of MVP’s crossings within the Commonwealth of Virginia. Because the central portion of the MVP traverses this District, and because 1,119 verifications are currently suspended along the majority of the pipeline route, this District finds it appropriate to suspend your authorization at this time. Therefore, exercising our authority under 33 CFR 330.5, we hereby suspend the December 19, 2017, and May 18, 2018 verification letters authorizing you to construct those portions of the MVP under NWP 12 within LRP. Effective immediately you must stop all activities conducted in reliance upon the authorization of the NWP 12. You may take measures necessary to stabilize any work in progress. This suspension will remain in effect until the authorization is reinstated, modified, or revoked. Within 10 days of receipt of this notice of suspension, you may request a meeting with the Pittsburgh District to present information on this matter. Within a reasonable -2period of time after this notice (or meeting, if requested), the Corps may take action to reinstate, modify, or revoke the authorization. If you have any questions and/or concerns about this permit verification suspension, please contact me via telephone at (412) 395-7188 or by email at jon.t.coleman@usace.army.mil.
