As part of a process for reviewing Environmental Protection Agency (EPA) research programs, the Committee was requested to conduct a review of the Alternative Technologies Research Program at the EPA Hazardous Waste Engineering Research Laboratory (HWERL) in Cincinnati. The broad review concentrated on the Program goals and progress in meeting those goals, on the relevance and responsiveness to needs of the Agency's regulatory programs, and on the relationship of the Program to other research being conducted in the Office of Research and Development (ORD), elsewhere in EPA and outside of EPA.
