The Hall County Board of Commissioners on Thursday approved Gainesville Waste and Recycling’s excavating part of the landfill on Old Athens Highway and its plan to control odor. Odor from the GWAR landfill was the subject of many complaints last year when the landfill was composting food waste, which was approved by the state Environmental Protection Division, but not zoned for that operation by the county. Speakers on the issue didn’t necessarily oppose the agenda item, but did raise concerns about hazardous material and the transportation of waste from the landfill.
