Air Quality IV: Mercury, Trace Elements, and
Particulate Matter
September 22-24, 2003
Marriott Crystal Gateway
Arlington, Virginia

Conference Summary

Conference Highlights
Endorsed by the North Dakota congressional delegation and the U.S. Secretary of Energy Spencer Abraham, the Air Quality IV Conference is the world's premier conference for reviewing the current state of science and policy for mercury, trace elements, and particulate matter in the environment.

Mercury and airborne particulate matter are two air pollutants that continue to receive much attention and be of great concern. Air Quality IV reviewed the current state of science and policy on airborne pollutants, mainly from utility power generation, with a focus on mercury and particulate matter emissions. Science, government, and business representatives met, discussed, and developed proactive responses to breakthroughs, questions, and concerns involving air quality. The conference provided a forum for industry, government, and research organizations to collectively discuss the environmental performance of the nation's future energy infrastructure.

More than 70 speakers from around the world presented papers covering two streams of topics: mercury and trace elements and particulate matter. The conference also included a poster session featuring more than 20 presenters and 15 exhibitors representing utilities and vendors worldwide.

Highlights of the conference included:

  • Opening keynote addresses by U.S. Senator Byron Dorgan (D-ND) and Jeffrey Holmstead, Assistant Administrator for Air & Radiation for the U.S. Environmental Protection Agency (EPA).
  • The opening panel of five internationally renowned business, environmental, science, and government experts who debated the environmental policy surrounding airborne pollutants.
  • A luncheon keynote address by Rita Bajura, Director of the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL), and Representative Earl Pomeroy (D-ND).
  • An evening banquet presentation by Senator Kent Conrad (D-ND).
  • A special appearance by Clay Jenkinson, who provided, in character, Thomas Jefferson's views on air quality and the environment.

Three preconference workshops given by Energy & Environmental Research Center (EERC) researchers were held on September 21, 2003.
