The U.S. Army Corps of Engineers has denied a request by the Atlanta-based Southern Environmental Law Center to reopen public comment on Hall County’s Glades Reservoir permit application. “Reopening scoping of the Environmental Impact Statement at this point in the process would not be appropriate and it would unnecessarily prolong the ... process,” according to a three-page letter from the corps obtained Tuesday by The Times. Gilbert B. Rogers, senior attorney at the law center, submitted the six-page written request Sept. 21 to the corps’ Savannah district on behalf of American Rivers, Georgia River Network, Chattahoochee Riverkeeper and Flint Riverkeeper.
