Purpose of ERTAC is to coordinate emissions inventories needed for air quality modeling, and provide a technical- (not policy-) driven process for developing and improving emissions inventories. These inventories will focus on the Eastern US.
First Meeting On January 22, 2008, representatives from GA, IL, MI, MO, NC, SESARM, and LADCO participated in a conference call to discuss the coordination of emissions inventories in the eastern half of the U.S. to support upcoming air quality analyses for ozone, fine particles (PM2.5), and regional haze.
The Eastern Regional Technical Advisory Committee (ERTAC) was formed by states (and their associated multi-jurisdictional organizations [MJOs]) in the eastern half of the U.S. to oversee this coordination.
Purpose of ERTAC: Two primary purposes were identified: (1) coordinate emissions inventories needed for air quality modeling, and (2) provide a technical- (not policy-) driven process for developing and improving emissions inventories. The inventory years of interest include a base year of 2008 and future years to be determined.
Membership: The core group will consist of 12-13 state/MJO representatives from the Northeast, Southeast, and Midwest, Each of the three regions will serve as chair for the core group conference calls on a rotational basis. Ad hoc workgroups will be formed, as necessary, to address specific technical issues and questions.
Operating procedures: The core group will provide direction, set priorities, establish schedules, and track progress. The core group will attempt to achieve consensus, promote consistency, and focus of important issues (i.e., those most likely to have the biggest impact in the air quality modeling). ERTAC strives to produce open sources of data and computer code that is transparent, open, and usable for all states.
Resource needs: It is unclear what additional resources will be needed to support inventory coordination. For now, in-kind support will be provided by the member states and MJOs.
ERTAC attempts to keep no more than 2 projects running at one time. This way we do not spread our resources too thin. Currently the two projects are
