How tall will Dominion Energy build the emission stacks?
Dominion Energy plans to build a compressor station directly across the Potomac River from Mount Vernon. While they claim the emission stacks will only be 50 feet tall Dominion Energy has submitted very conflicting data to the Maryland Department of Energy and the Federal Energy Regulatory Commission.

114. Theresa Lazar states that air will be trapped near her home due to a 100-foot-high hill to the east of the Charles Station. But the station site is not surrounded by hills that would trap air within a low valley. Also, the compressor units at the Charles Station will discharge exhaust at a minimum speed of 15.84 meters per second from stacks reaching 83 feet above ground level.200
