The U.S. EPA invites interested stakeholders to participate in a laboratory-based technical workshop that will focus on the conduct of the Association of Official Analytical Chemists (AOAC) Use-dilution method (UDM) and the status and implementation of a new test method, the Organization for Economic Cooperation and Development (OECD) Quantitative Method for Evaluating Bactericidal Activity of Microbicides Used on Hard, Non-Porous Surfaces. The workshop is being held to discuss current and proposed revisions mainly associated with the Staphyloccocus aureus and Pseudomonas aeruginosa methodologies. The goals of the workshop are to provide a comprehensive review and discussion period on the status of the UDM and OEDC methods integrated with hands-on laboratory demonstrations. An overview of various data sets and collaborative studies will be used to supplement the discussions which will be held at the EPA Environmental Science Center Microbiology Laboratory.

EPA is proposing to extend the grace period before the MOtor Vehicle Emission Simulator model (currently MOVES2010a) is required for regional emissions analyses for transportation conformity determinations (``regional conformity analyses''). This proposal would provide an additional year to the previously established two-year conformity grace period, so that MOVES2010a would not be required for regional conformity analyses until March 2, 2013. This proposal would not affect EPA's previous approval of the use of MOVES in official state air quality implementation plan (SIP) submissions or the existing grace period before MOVES2010a is required for carbon monoxide and particulate matter hot-spot analyses for project-level conformity determinations.

EPA is proposing to approve a revision to the Indiana State Implementation plan (SIP) submitted by the Indiana Department of Environmental Management (IDEM) on November 24, 2010. The SIP revision consists of amendments to 326 Indiana Administrative Code (IAC) 8-2-1 and 326 IAC 8-2-9, the applicability sections for Indiana's miscellaneous metal and plastic parts surface coating rules. These rules are approvable because they satisfy the requirements of the Clean Air Act (CAA) for volatile organic compound (VOC) reasonably available control technology (RACT) rules.
