Notice of Data Availability on the Disposal of Coal Combustion Wastes in Landfills and Surface Impoundments

Riepilogo

This notice announces the availability of new information and data contained in three documents that the Agency is requesting public comments on concerning the management of coal combustion wastes (CCW) in landfills and surface impoundments. The Agency is seeking public comments on how, if at all, this additional information should affect the Agency's decisions as it continues to follow-up on its Regulatory Determination for CCW disposed of in landfills and surface impoundments. The three documents that the Agency is requesting comment on include: a joint U.S. Department of Energy (DOE) and EPA report entitled, Coal Combustion Waste Management at Landfills and Surface Impoundments, 1994-2004; a draft risk assessment conducted by EPA on the management of CCW in landfills and surface impoundments; and EPA's damage case assessment. The Agency solicits comments on the extent to which the damage case information, the results of the risk assessment, and the new liner and ground water monitoring information from the DOE/ EPA report should affect the Agency's decisions. EPA is also requesting direct comment on the draft risk assessment document to help inform a planned peer review. In addi
