Restoration projects for the now canceled Atlantic Coast Pipeline (ACP) and Supply Header Project (SHP), which would have carried 1.5 Bcf/d from Appalachia, are unlikely to cause significant environmental impacts based on the mitigation measures planned, according to FERC.

Dominion Energy and joint venture partner Duke Energy last year canceled the 600-mile, 1.5 Bcf/d ACP, designed to run from West Virginia into Virginia and North Carolina. The related SHP system also was canceled.

The staff of the Federal Energy Regulatory Commission in July had determined in a draft environmental impact statement (EIS) that restoring lands impacted by the scuttled systems would likely be able to avoid or reduce impacts to less than significant levels.

The sponsors, Atlantic Coast Pipeline LLC and Eastern Gas Transmission and Storage Inc., are proposing to stabilize the lands that were affected by the previous construction efforts. The projects are part of ceasing all project-related activities. 

The restoration projects, “with the mitigation measures discussed” in the supplemental EIS, would continue to avoid or reduce impacts to less than significant levels, “with the exception of climate change impacts, for which FERC staff is unable to determine significance,” it noted.

The final supplemental EIS was issued earlier in December to comply with the National Environmental Policy Act. The U.S. Fish and Wildlife Service and the U.S. Department of Agriculture – Forest Service were cooperating agencies.

The supplemental EIS determination, said FERC staff, was based on reviewing the information filed by the sponsors “and developed further using data requests, scoping, literature research and contacts with federal agencies.”

In the review, staff developed specific mitigation measures that it determined would appropriately and reasonably reduce the environmental impacts resulting from restoration activities. 

The Commission is to consider the staff recommendations when the decisions are made about the restoration projects.
