Organizational Changes at FHWA. Associate Administrator Gloria Shepherd recently announced changes in the Headquarters Office of Planning, Environment, and Realty. Notably, she created a new Sustainable Transport and Climate Change Team (HEPN-40) composed of staff from several disciplines. In addition, the former Air Quality and Transportation Conformity teams have been consolidated under team leader Cecilia Ho, (HEPN-10). Both teams are within the Office of Natural and Human Environment (HEPN). The former Water & Ecosystem Team has been renamed the Project Mitigation Team (HEPE-30) and is now part of the Office of Project Development and Environmental Review (HEPE).

FHWA Launches Economic Recovery Web Page. In anticipation of the Economic Recovery Legislation currently being discussed in Congress and to assist our state and local partners in preparing for the implementation of this program, the Federal Highway Administration has established an economic recovery Web page located at A series of key questions and answers (Q&As) has been posted and will be updated as more information becomes available. The web page also includes a list of actions that can be taken to expedite the Economic Recovery Delivery. FHWA encourages all potential recipients of highway-related economic recovery funding to review and move forward on those items that are applicable.

EPA Releases Proposed Rulemaking on 8-hour Ozone Implementation. On January 9, EPA released a proposed rule that addresses two areas: 1) implementation of the 8-hour ozone standard in areas classified under Subpart 1 of the Clean Air Act (CAA), and 2) implementation of the 8-hour ozone standard in former 1-hour ozone nonattainment and maintenance areas. EPA proposes to classify all remaining subpart 1 nonattainment areas under subpart 2 of the CAA. EPA is also proposing that 1-hour ozone contingency measures continue to apply until an area attains the 1997 8-hour ozone NAAQS.

The conformity implications of this proposed rulemaking are that nonattainment areas previously classified under subpart 1, that are still designated nonattainment, would be classified under subpart 2 as either marginal or moderate nonattainment areas, depending on the data initially used to designate the area in 2004. However, it is important to note that current conformity determinations would remain valid, and are not impacted by the proposed action. No new conformity deadline would be triggered. Areas designated as moderate would be provided 12 months after the effective date of designation to meet the additional conformity requirements (40 CFR 93.119(b)(1)). Comments are due on or before February 17, 2009. For more information, see: the Fact sheet at and Proposed rule at

EPA Proposes to Disapprove Seven Ozone SIPs.EPA announced on January 9 that it has proposed 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. As of January 28 the Federal Register Notice had not been issued. The fact sheet on this proposed action can be found at: There will be a 30-day comment period once the Federal Register Notice is posted.

EPA Proposes Revision to Air Quality Index for Particle Pollution. EPA is proposing to update its Air Quality Index (AQI) to reflect the latest standards for fine particle pollution. The proposal would set a "significant harm" level, which states use in developing emergency episode plans. Under the proposed changes, the AQI would reach "code orange", unhealthy for sensitive groups, when particle pollution levels reach 35.5 micrograms per cubic meter of air. The changes would also mean that air quality reaches the "unhealthy" category at a lower particle pollution level. EPA will take comments for 60 days after the proposal is published in the Federal Register. EPA will hold a public hearing March 5, 2009 in the Dallas area. For more information, see:
