ACTION: Notice of external review draft for public review and comment. SUMMARY: The U.S. Environmental Protection Agency
(EPA)is announcing a 30-day public review and comment period for the draft Web site, “2010 release of the Causal Analysis/Diagnosis Decision Information System (CADDIS).” The CADDIS Web site was developed and prepared by EPA's National Center for Environmental Assessment (NCEA), in the Office of Research and Development (ORD). EPA will consider public comments submitted in accordance with this notice and may revise the draft Web site thereafter. The draft 2010 CADDIS Web site is available at *http://caddis-review.tetratech-ffx.com/index.html.* DATES: The public comment period begins June 22, 2010, and ends July 22, 2010. Comments should be in writing and must be received by EPA by July 22, 2010. Comments may be submitted electronically via *http://www.regulations.gov,* by e-mail, by mail, by facsimile, or by hand delivery/courier. Please follow the detailed instructions provided in the SUPPLEMENTARY INFORMATION section of this notice. FOR FURTHER INFORMATION CONTACT: For information on the docket, *http://www.regulations.gov,* or the public comment period, please contact the Office of Environmental Information

Information About CADDIS Over a thousand water bodies in the United States are listed by states as biologically impaired. For many of these sites, the cause of impairment is reported as “unknown.” Before appropriate management actions can be formulated for impaired water bodies, the causes of biological impairment ( *e.g.,* excess fine sediments, nutrients, or toxics) must be identified. Effective causal analyses require knowledge of the mechanisms, symptoms, and stressor-response relationships for various stressors, as well as the ability to use that knowledge to draw appropriate, defensible conclusions. To aid in these causal analyses, NCEA developed CADDIS, which is a web-based decision support system that will help regional, state, and tribal investigators find, access, organize, and share information useful for causal evaluations in aquatic systems. CADDIS is based on EPA's Stressor Identification process, which is a formal method for identifying causes of impairments in aquatic environments. Features include a step-by-step guide to conducting causal analysis; examples and applications; a library of conceptual models; and an online application for collaborating on conceptual diagrams and using them to update and access a database of supporting literature, information on basic and advanced data analyses, downloadable software tools, and links to outside information sources.
