wastes from a single industry are eligible for variances from the requirements to install liners,
leachate-collection systems, and groundwater and surface water monitoring systems, if it can be
demonstrated in the permit application that the waste to be disposed of would not cause
groundwater or surface water contamination. In the absence of a variance, disposal facilities
accepting wastes from more than one industrial source, unless the facility is a monofill, must
meet all standards applicable to municipal solid waste landfills (GDNR Rule 391-3-4.07(4)).
The design standards for industrial waste landfills in Georgia do not apply to surface
impoundments. However, a surface impoundment that receives industrial wastes such as CCWs
must have an NPDES permit if it will discharge any pollutant from a point source into waters of
the State, including both surface waters and subsurface waters (GDNR Rule 391-3-6-.06 (3)(a)).
If there will be a nonpoint-source discharge, a surface impoundment that receives industrial
wastes such as CCWs must have written approval for the discharge, either in the NPDES permit,
if there is also a point-source discharge, or in a letter. In either case, liner requirements may be
established, as necessary, on a case-specific basis to protect subsurface waters (GDNR Rule 391-
3-6(14)).
