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.
