EPA Region 10 proposed to approve a modification to Alaska's municipal solid waste landfill program concerning research, development, and demonstration permit requirements; see above for direct final rule.

DOE proposed to amend its existing regulations governing compliance with NEPA, particularly its categorical exclusions.

EPA entered into a proposed administrative settlement under CERCLA that requires 275 de minimis settling parties to pay $17,027,998 in U.S. response costs incurred at the Operating Industries, Inc., Superfund site in Monterey Park, California.

EPA finalized amendments to Method 301, Field Validation of Pollutant Measurement Methods From Various Waste Media.

EPA delayed the effective dates for the final rules titled "National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters" and "Standards of Performance for New Sources and Emission Guidelines for Existing Sources: Commercial and Industrial Solid Waste Incineration Units" until judicial review and Agency reconsideration are completed.

EPA granted a petition submitted by Owosso Graphic Arts Inc. in Owosso, Michigan, to exclude from the list of hazardous waste up to 244 cubic yards of wastewater treatment sludge per year.

This action approves a modification to Alaska's approved 
Municipal Solid Waste Landfill (MSWLF) permit program. The approved 
modification allows the State to issue Research, Development, and 
Demonstration (RD&D) permits to owners and operators of MSWLFs in 
accordance with its State law. On March 22, 2004, EPA issued final 
regulations allowing RD&D permits to be issued to certain MSWLFs by 
approved States. On September 7, 2010, the State of Alaska submitted an 
application to EPA Region 10 seeking Federal approval of its RD&D 
requirements. After thorough review, EPA Region 10 has determined that 
Alaska's RD&D permit requirements are adequate through this direct 
final action.

EPA Region 10 approved a modification to Alaska's municipal solid waste landfill program concerning research, development, and demonstration permit requirements.
