2011 US EPA Regional, State, and Local Dispersion Modeling Workshop

The 2011 U.S. EPA Regional, State, and Local Modelers Workshop is scheduled to be held in Atlanta, Georgia from June 6-9. This annual Workshop is intended to provide a forum where federal, state, and local levels of the air modeling community have the opportunity to discuss various technical aspects and convey lessons learned regarding local-scale air quality modeling.

Topics to be discussed include recent updates to the AERMOD and CALPUFF modeling systems, Model Clearinghouse, as well as numerous important workgroup updates from AERMIC, AWIG, OAQPS, IWAQM, NPS, and FLM.


This year is unique in that the U.S. EPA Workshop has traditionally only been open to EPA Personnel, State, local, and tribal agency modelers. However, this year for the first time, on Thursday June 9, a technical session with industry and private sector modelers will be held to exchange important information regarding regulatory permit modeling issues such as NO2, SO2, and PM2.5. Additional agenda items include:

The complete agenda is available on the following link:

Step 2: The Export to Google Earth dialog is displayed. From the navigation tree located on the left, select the Location option.

Step 3: If your meteorological data file is in SAMSON format, then the Latitude and Longitude of your met station will be automatically read from the header of the file. If the location of the met station cannot be found, then you must specify it under the Location page.

You can specify the location in two ways:

  • Latitude and Longitude or
  • X and Y UTM Coordinates and UTM Zone

Step 4: After you specify the met station location, select the Style option from the navigation tree on the left. From the Rose Plot Style page, you will be able to specify the following options:

EPA to Hold Three Public Hearings on National Standard for Mercury Pollution from Power Plants

WASHINGTON - May 3, 2011 - The U.S. Environmental Protection Agency (EPA) will hold three public hearings in May on the proposed mercury and air toxics standards. The new power plant mercury and air toxics standards would require many power plants to install widely available, proven pollution control technologies to cut harmful emissions of mercury, arsenic, chromium, nickel and acid gases, while preventing as many as 17,000 premature deaths and 11,000 heart attacks a year.

EPA Publishes National U.S. Greenhouse Gas Inventory

WASHINGTON - April 18, 2011 - The U.S. Environmental Protection Agency has released the 16th annual U.S. greenhouse gas inventory. The final report shows overall emissions during 2009 decreased by 6.1 percent from the previous year. This downward trend was attributed to a decrease in fuel and electricity consumption across all U.S. economic sectors.

Total emissions of the six main greenhouse gases in 2009 were equivalent to 6,633 million metric tons of carbon dioxide. These gases include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. The report indicates that overall emissions have grown by more than 7.3 percent from 1990 to 2009. Emissions in 2009 represent the lowest total U.S. annual GHG emissions since 1995. These numbers reflect the most up to date data at the time of publication.

Following conversations with industry and others and in the interest of providing high quality data to the public this year, EPA is extending this year’s reporting deadline to September 30, 2011. This extension will allow EPA to further test the system that facilities will use to submit data and give industry the opportunity to test the tool, provide feedback, and have sufficient time to become familiar with the tool prior to reporting.
