EPP2010: Elementary Particle Physics in the 21st Century

In the 21st century, elementary particle physics is poised to address some of the most basic questions in science. Obtaining the answers to these questions will require a global effort of great scale and complexity. To address these questions, the National Research Council has formed a committee, EPP2010, which is charged to ``Identify, articulate, and prioritize the scientfic questions and opportunities that define elementary particle physics,'' and ``Recommend a 15-year implementation plan with realistic, ordered priorities to realize these opportunities.'' The activities and progress of this committee will be discussed.
