EPA proposed to incorporate American Society for Testing and Materials standards to allow the use of alternatives to mercury-containing industrial thermometers.

EPA is providing notice of, and soliciting written comments 
on, a tentative determination to deny an administrative petition 
submitted by the Sierra Club under RCRA section 7004. EPA issued an 
earlier notice denying this same petition in November 2008. However, 
the Agency at that time failed to comply with notice and comment 
provisions in its regulations. Accordingly, we are now giving the 
public the opportunity to provide comments on this tentative decision. 
This petition requests EPA to reconsider the final rule, ``Regulation 
of Oil-Bearing Hazardous Secondary Materials from the Petroleum Refining Industry 
Processed in a Gasification System to Produce Synthesis Gas,'' 
published in the Federal Register on January 2, 2008. The EPA 
considered the petition, along with information contained in the 
rulemaking docket, and has tentatively decided to deny the petition. In 
a letter from EPA Assistant Administrator Mathy Stanislaus dated 
January 21, 2011, EPA provided the petitioner with its tentative 
decision to deny the petition for reconsideration. The letter explains 
EPA's reasons for tentatively deciding to deny the petition. After 
evaluating all public comments, as well as any other information in the 
rulemaking record, EPA will publish either a final denial of the 
petition or issue a proposed rule to amend or repeal the regulation.

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.
