EPA’s Office of Research and Development and Office of Solid Waste requested a review of the 3MRA modeling system, because 3MRA represented the first comprehensive and integrated risk assessment technology for assessing human health and enviornmentla impacts related to programs under the Resource Conservation and Recovery Act. The goal of 3MRAl was to provide a flexible and consistent tool for estimating the distributions of the probability of exceeding adverse effect benchmarks.
