In 1982, a small sewage water holding pond located beneath the
sewage treatment plant was constructed to intercept and hold
effluent from the sewage treatment plant. In January 1991, the
Division approved a soil storage site on the location formerly
occupied by this pond as construction of the West Ridge Waste
Pile moved up-slope into the area of the pond. This topsoil has
now been spread on the waste pile and the former stockpile
reclaimed.
