In late May 2014, landowners in western and central Virignia received letters from Dominion about a new pipeline. Initially called the Southeast Reliability Project, the proposed Atlantic Coast Pipeline LLC (ACP) was a project of Dominion Energy, Inc., and Duke Energy, Corporation. The ACP was a proposed 48 inch, 1400 psi pipeline intended to bring fracked natural gas from the Marcellus Shale Fields in West Virginia through West Virginia, then southeast into Virginia (including Highland, Bath, Augusta, Nelson, and Buckingham Counties) into North Carolina, to an originally planned terminus near Lumberton, NC. After delays brought about by intense opposition to the ACP and by its ballooning cost, Dominion and Duke announced cancellation of the proposed project on 5 July 2020.

The Federal Energy Regulatory Commission (FERC) is an independent federal agency that regulates the interstate transmission of natural gas, oil, and electricity. FERC also regulates natural gas and hydropower projects, issues documents and rulings related to projects under consideration, as well as requesting information from the proposers. Beginning in 2014, FERC held several hearings on the Atlantic Coast Pipeline. FERC also solicited written comments by citizens and groups on the initial docket number PF15-6, and then on the permanent docket number CP15-554.

Section 106 of the National Historic Preservation Act of 1966 (NHPA) requires federal agencies to consider the effects on historic properties of projects they carry out, assist, fund, permit, license, or approve. Thus, as part of its Federal Energy Regulatory Commission (FERC) application process, Dominion was required to survey historic and archaeological resources on the proposed Atlantic Coast Pipeline route. Under the Section 106 process, organiztaions such as historical societies could become consulting parties in order to ensure that cultural resources, including historical structures and archaeological resources were properly surveyed and protected. Surveys often required mitigation efforts, and consulting parties could review and request revision of plans and documents related to the mitigation process. Because FERC did not follow Section 106 requirements, it was two years before the Augusta and Nelson historical societies were abl to get their respective Boards of Supervisors to request and get consulting party status. Included here are materials on historic, archaeological, and cultural resources relevant to locales in the region.
