Consensus Study Report


At the request of the U.S. Environmental Protection Agency (EPA), the present letter report evaluates the effectiveness of EPA's Title 42 program. Title 42 authority was granted to EPA for 5 years, from 2006 to 2011. As that period draws to a close, it was thought that a review of the current program would be appropriate.

This letter report first provides some background information on the origin of EPA's Title 42 program and then more detailed information on the committee's task and its approach to the task, comments on implementation of the Title 42 program, and suggestions for strengthening the program. The report concludes with the committee's overall findings and recommendations. Although the Title 42 program at EPA is still evolving, the committee found that the agency has implemented the program appropriately. Most important, the Title 42 appointees have already had a favorable effect on EPA's scientific research even after such a short time since implementation of the program. A leading example is the development of the National Center for Computational Toxicology.
