The Lime Lake Reclamation Project of PPG Industries (Baberton, OH) received special awards in the National Beneficial Use of Biosolids Program from Environmental Protection Agency’s region in 1998. However, the same facility was accused by EPA of clean-air violations later, in 2006. According to the agency’s report, PPG failed to comply with a 1-pound per hour permitted emission limit on volatile organic compounds. The tests done in January and February of the same year showed VOC emissions as high as 8.8 pounds per hour.
