Background: On August 29, 2007, EPA published a Notice of Data Availability (NODA) in the Federal Register that announced the availability of new information and data contained in three documents regarding the management of coal combustion wastes (CCW) in landfills and surface impoundments. (72 FR 49714.) The Agency sought public comments on how, if at all, this additional information should affect EPA'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 requested comment on included: The joint U.S. Department of Energy (DOE) and EPA report entitled, Coal Combustion Waste Management at Landfills and Surface Impoundments, 1994-2004; the draft risk assessment conducted by EPA on the management of CCW in landfills and surface impoundments entitled, Human and Ecological Risk Assessment of Coal Combustion Wastes; and the EPA's damage case assessment. (The Agency also included in the Docket to the NODA a rulemaking petition submitted by a number of citizens' groups and several approaches, one prepared by the electric utility industry and the other prepared by a number of citizens' groups regarding the management of CCW). The Agency solicited information regarding the damage cases, the results of the risk assessment, and the new liner and groundwater monitoring information from the DOE/EPA report. EPA also requested comment on the draft risk assessment document to help inform a planned peer review, with which this notice is associated. In addition to the draft risk assessment, EPA will also make available to the peer reviewers the public comments regarding the draft risk assessment that were submitted during the comment period, which closed on February 11, 2008.
