Announcements and Recent Events

Draft MOVES Model Released by EPA. EPA recently released its Draft MOVES2009 model which is a major update to EPA's mobile source emission rate models. The Motor Vehicle Emission Simulator, (MOVES), model and supporting documentation are available at: The draft MOVES model is not approved for use in either SIP submissions or for making conformity determinations. Nor is it approved for use for PM2.5 or PM10 hot-spot analyses or to be used as part of NEPA analysis requirements. See the EPA website above for questions and answers on MOVES and to make comments on the draft MOVES model.

FHWA Issues Broad Agency Announcement (BAA) to Solicit Research Proposals. FHWA recently issued a "Transportation and Air Quality Emissions Analysis' BAA solicitation for research and development projects that could lead to better understanding and advances for tools and methodologies in conducting emissions analysis for transportation projects in the United States. Four research focus areas have been identified: 1) Testing, Evaluation and Validation of New Emission Models and Methodologies, 2) Research on Conducting Project Level Analysis, 3) Air Quality and Transportation Conformity Outreach and Communication, and 4) Fleet Data for On-road Mobile Sources Emissions Inventory.

EPA's Actions on 1997 Ozone NAAQS State Implementation Plans. On April 29, EPA signed seven Federal Register (FR) notices to propose disapprovals of ozone SIPs for five states and is also making a finding that two states missed the June 15, 2007 SIP submittal deadline for ozone SIPs. The fact sheet on this proposed action can be found at: EPA will accept public comment for 30 days on the proposed action and then take final action.

EPA Finds Greenhouse Gases Pose Threat to Public Health, Welfare. On Friday, April 17, EPA issued a proposed finding that greenhouse gases contribute to air pollution that may endanger public health or welfare. This finding results from a thorough scientific review ordered in 2007 by the U.S. Supreme Court. The proposed finding, which will be open for public comment period, identified six greenhouse gases that pose a potential threat. The proposed endangerment finding does not include any proposed regulations. Before taking any steps to reduce greenhouse gases under the Clean Air Act, EPA must conduct an appropriate process and consider stakeholder input. For more information see:!OpenDocument.

EPA Releases Report on Potential Impacts of Climate Change on Regional U.S. Air Quality. EPA recently released the report "Assessment of the Impacts of Global Change on Regional U.S. Air Quality: A Synthesis of Climate Change Impacts on Ground-Level Ozone'. The report suggests that there is potential for climate change to make ozone pollution worse in some regions and that future ozone management decisions may need to account for the impacts of climate change. For more information see:

EPA Awards $3.5 Million for Particulate Matter Research. On April 3, EPA awarded four grants to universities to research the relationship between particulate matter (PM) and health effects.
