Environmental Protection Agency January 27, 2011 – Federal Register Recent Federal Regulation Documents

EPA is convening a public workshop to discuss issues related to the evaluation of health risks associated with exposures to air pollutant mixtures, focusing on the criteria air pollutants. This workshop is being jointly sponsored and organized by EPA's National Center for Environmental Assessment, Office of Air Quality Planning and Standards, Office of Research and Development, and the Health Effects Institute. The workshop will be held February 22-24, 2011, at the Carolina Inn in Chapel Hill, North Carolina. Although the workshop is open to the public, space is somewhat limited and registration is on first come-first served basis.

The EPA (also, ``the Agency'' or ``we'' in this preamble) is granting a petition submitted by Owosso Graphic Arts Inc. (OGAI), in Owosso, Michigan to exclude (or ``delist'') up to 244 cubic yards of wastewater treatment sludge per year from the list of hazardous wastes. The Agency has decided to grant the petition based on an evaluation of waste-specific information provided by OGAI and a consideration of public comments received. This action conditionally excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when disposed of in a Subtitle D landfill permitted, licensed, or registered by a State to manage industrial solid waste. The rule also imposes testing conditions for waste generated in the future to ensure that this waste continues to qualify for delisting.
