Backtracking
The irony is that by objecting to the expansion plans on environmental grounds, aircraft will continue to have to backtrack r/w 20 which means holding other aircraft in a take off queue behind both other take offs and/or landing burning fuel unnessesarily. However, when 02 is in use backtracking can be avoided by departing from the south taxiway intersection as the performance of Dash 8 on the short routes should be able to accommodate full loads.
