Engineering Technical Support Center (TSC) - NRMRL
Contact: Dave Reisman, 513-569-7588
The Engineering Technical Support Center (TSC) provides site-specific assistance on engineering and treatment issues during any phase of a site
cleanup. Focus areas include containment, thermal treatments, soil vapor extraction, bioremediation, and solidification/stabilization. Support
is provided for incorporating technology-based data needs in the RI/FS phase and conducting/evaluating site-specific remedy options in the RD/RA
and post-construction phases. The center publishes Engineering Bulletins on technologies and site types. The center supports Superfund, Brownfields,
and RCRA Corrective Action sites.
Ecological Risk Assessment TSC - NCEA
Contact: Michael Kravitz, 513-569-7140
The Ecological Risk Assessment Support Center (ERASC) will provide technical and management support and arrange for scientific review and consistency
on topics relevant to ecological risk assessment and ecological concerns. NCEA will manage the Center, but it is understood that it will routinely
be necessary to access the expertise that is located in various ORD laboratories and centers. The Center Director will arrange for this access as
appropriate.
Monitoring and Site Characterization TSC - NERL
(http://www.epa.gov/nerlesd1/tsc/tsc.htm)
Contact: J. Gareth Pearson, 702-798-2270
The Technical Support Center for Monitoring and Site Characterization provides scientific and technical assistance in the characterization of hazardous waste sites and associated site contaminants. State-of-the-science methods and technologies are identified and applied to identify contaminants, determine their levels and concentrations, and identify their geographic extent and distribution for site characterization and remediation.
Superfund Health Risk TSC - NCEA
Contact: Harlal Choudhury, 513-569-7536
The Superfund Health Risk Technical Support Center (STSC) supports regional and headquarters Superfund risk assessors by reviewing and developing
exposure and toxicity factors that allow more accurate quantitative estimates of risk to be developed. Much of the activity is focused on developing
new and updated peer reviewed provisional toxicity values that describe dose-response toxicological relationships. External peer review of the
provisional toxicity values was initiated in FY1999. The Center also provides user support through the STSC Hotline, as well as onsite expertise
reviews. All assistance is provided on a rapid turn-around basis.
Center for Exposure Assessment Modeling (CEAM)
(http://www.epa.gov/ceampubl/)
Contact: Frank Stancil, 706-355-8100
The goals of the Center for Exposure Assessment Modeling (CEAM) are to develop, maintain, and apply state-of-the-science technical tools including
multimedia exposure and ecosystem response simulation models, environmental databases, data analysis packages, tool application strategies, and
advanced educational materials in the environmental sciences.
