In August of 2004, the new EPA Remediation and Characterization Innovative Technology (REACH IT) database web site was released with major upgrades to the search options such that finding characterization or remediation technologies for a particular problem set is now much more streamlined. Additionally, there has been a thorough effort to update the information associated with the more than 450 technology vendors and 700 plus technologies in REACHIT. New features, in addition to the streamlined navigation, include the following: One-click access to searches on topics of interest to the remediation community (the Spotlight section), the most commonly searched technologies and contaminants, and customized user-created queries; faster searches for specific vendors, technology trade names, and sites with alphabetical indexes; one-click downloading of search results in a spreadsheet format; and, summary of EPA REACH IT data in the Information Snapshots section. See http://www.epareachit.org . Clarifying Cleanup Goals and Identification of New Assessment Tools for Evaluating Asbestos at Superfund Sites (OSWER No. 9345.4-05). This guidance was issued by the EPA Office of Superfund Remediation and Technology Innovation. Its purpose is to clarify that EPA Regions should develop risk-based, site-specific action levels to determine if response actions should be taken when materials containing less than 1 percent asbestos (including chrysotile and amphibole asbestos) are found at a site. The second purpose is to outline some activities underway to assist in the evaluation of asbestos risks at Superfund sites (August 2004, 4 pages).

Risk Assessment Guidance for Superfund (RAGS), Volume I: Human Health Evaluation Manual (Part E, Supplemental Guidance for Dermal Risk Assessment) (OSWER No. 9285.7-02 EP). This guidance is the fifth annex of the Risk Assessment Guidance for Superfund (RAGS), Volume I, addressing human health risk at Superfund sites. This dermal risk guidance was developed by a workgroup composed primarily of toxicologists and risk assessors from Regional Superfund programs, with additional participation from the Office of Research and Development (ORD) and the Office of Solid Waste and Emergency Response (OSWER). Part E contains methods for conducting dermal risk assessments. TechDirect: September 1, 2004 3 of 6 clu-in.ora/newsletters ------- EPA has found these methods generally to be appropriate. However, for each dermal risk assessment, Regions must decide whether these methods, or others, are appropriate, depending on the facts (July 2004, 181 pages).
