Community Cumulative Assessment Tool (CCAT)
CCAT is a computerized, guided process that informs users of the steps involved in a cumulative risk assessment (CRA), such as problem formulation, conceptual model development, and the consideration of multiple stressors; it is based strongly on EPA CRA recommendations. It clarifies relationships between stressors, sources, and health effects; highlights decision points in the cause-effect chain where actions could improve health and the environment; and helps identify areas of highest uncertainty. CCAT pays particular attention to susceptible and vulnerable populations and a range of chemical and non-chemical stressors to further inform EJ assessments. It accesses informational resources such as C-FERST and GeoPlatform to inform the CCAT decision-making process. A CCAT prototype is complete; a beta-test version will be available for limited stakeholder use, testing, and evaluation in early 2013; a final version will be ready for review, clearance, and distribution in the second half of 2013, followed by public release.
