Environmental Protection Agency February 2, 2005 – Federal Register Recent Federal Regulation Documents

In this notice, EPA is notifying the public that EPA has found that the motor vehicle emissions budgets in the Metro-East St. Louis, Illinois 1-hour ozone maintenance plan are adequate for conformity purposes. On March 2, 1999, the DC Circuit Court ruled that submitted State Implementation Plans (SIPs) cannot be used for conformity determinations until EPA has affirmatively found them adequate. As a result of our finding, Metro-East St. Louis can use the motor vehicle emissions budgets from the submitted 1-hour ozone maintenance plan for future conformity determinations. These budgets are effective February 17, 2005. The finding and the response to comments will be available at EPA's conformity Web site: https://www.epa.gov/otaq/transp.htm, (once there, click on the ``Conformity'' button, then look for ``Adequacy Review of SIP Submissions for Conformity'').

EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the State of Missouri for the purpose of establishing vapor line requirements necessary to achieve Stage I vapor recovery air quality benefits in Clay, Jackson, and Platte counties in Missouri.

On or about January 31, 2005, the Office of Air Quality Planning and Standards (OAQPS) of EPA will make available for public review and comment a draft document, Review of the National Ambient Air Quality Standards for Particulate Matter: Policy Assessment of Scientific and Technical Information (Second Draft Staff Paper). The purpose of the Staff Paper is to evaluate the policy implications of the key scientific and technical information contained in a related EPA document, Air Quality Criteria for Particulate Matter, required under sections 108 and 109 of the Clean Air Act (CAA) for use in the periodic review of the national ambient air quality standards (NAAQS) for particulate matter (PM). The OAQPS also will make available for public review and comment a related draft technical support document, Particulate Matter Health Risk Assessment for Selected Urban Areas (Second Draft Risk Assessment).
