Toxic Sludge Controversy
In 1998, PPG's "Lime Lake Reclamation Project" in Barberton, OH, received awards from the Environmental Protection Agency for "National Beneficial Use of Biosolids" (toxic sewage sludge) in 1998. In 2006, however, the EPA cited the same PPG plant for alleged clean-air violations, stating that it "failed to comply with a 1-pound per hour permitted emission limit on volatile organic compounds from its air stripper, which removes the VOCs from wastewater by contacting the water with air. Tests done in January and February at EPA's request showed VOC emissions as high as 8.8 pounds per hour."
Then, in October, 2011, Lime Lakes Energy LLC, a subsidiary of Cleveland-based Quasar Energy Group, received $2 million in federal funds from the USDA to construct a $4.5 million anaerobic digester in cooperation with PPG. "The plant, scheduled to be fully operational by January, will turn sewage sludge into compressed natural gas for vehicles," the Beacon Journal reports. "Leftover wastes from the operation will be used to speed up the reclamation of Lime Lake 6 by PPG Industries." According to the Quasar Energy Group website, "For more than 70 years, PPG produced soda ash to make plate glass at the Barberton plant. The liquid and solid wastes were pumped from the soda ash operation into six ponds covering more than 600 acres. The result of the historically accepted practice created 'lime lakes,' where the fine-grained spoil is too alkaline and lacks nutrients to support vegetation. Since 1985, [Ohio EPA] approved biosolids have been mixed on site with the lime spoil to create a stable soil matrix that supports long-term vegetation growth and wildlife habitat."
This "remediation" doesn't address the long list of contaminants in toxic sludge itself, which include Dioxins and Furans, Flame Retardants, Metals, Organochlorine Pesticides, 1,2-Dibromo-3-Chloropropane (DBCP), Naphthalene, Triclosan, Nonylphenols, Phthalates, Nanosilver, and thousands more substances.
