EPA Releases Advanced Notice of Proposed Rulemaking (ANPRM).

On July 30, 2008 the U.S. EPA released an ANPRM for review and comment on analyses and policy alternatives regarding greenhouse gas (GHG) effects and regulations under the Clean Air Act. Comments are due November 28, 2008. This notice includes both the Preamble to the proposed rulemaking that provides voluminous detail on issues that EPA is seeking input on, and observations and issues raised by other federal agencies during the interagency review process related to the ANPRM. EPA is seeing comment on both to help them frame the issue going forward. For more information, see:

EPA Approves TCM Substitution in Massachusetts SIP. On July 31, 2008 the EPA approved a State Implementation Plan (SIP) revision submitted by the Commonwealth of Massachusetts. This revision changes completion dates of delayed transit projects, provides interim deadlines for projects, maintains requirements for interim emission reduction offsets in the event a project becomes delayed, modifies the project substitution process, revises the list of required transit projects, and expands public participation in and oversight of the projects. The intended effect of the action is to substitute specific transit projects and 1,000 park and ride spaces to replace certain transit projects currently approved into the SIP, and approve modifications to the delay and substitution procedures for transit projects.

Proceedings Available - October 2007 Particulate Matter Hot-Spot Analysis Peer Exchange Meeting.On October 23-24, 2007 subject matter experts on particulate matter (PM) gathered at Allerton Park in Monticello, Illinois to exchange ideas and experiences in project level hotspot analysis of PM, including monitoring and compliance. The attendees included staff from five Midwestern state Departments of Transportation (DOTs), metropolitan planning organizations, the U.S. EPA, the Illinois EPA, University faculty, and the FHWA.

The proceedings of the peer exchange are now available. In general, the peer exchange participants are concerned with making sure their new transportation projects are in compliance with the recently released U.S. EPA regulations for performing PM hot-spot analyses. The meeting offered the attendees opportunities to identify hot-spot requirements, discuss PM modeling uncertainties and monitoring of PM, and learn about how other states are documenting the analyses in reports. Outcomes of the meeting included documented challenges in practice, research needs, and practical guidelines which will be useful to all state DOTs. For a copy of the proceedings, see
