David Ferguson An international workshop on treat- ment, disposal, and waste minimization of pesticides and pesticide wastes was held in Cincinnati, OH, on February 26- 27,1991. The purpose of this workshop was to work with government, pesticide user groups, pesticide producers, farm organizations, and academia to define and offer practical solutions to pesti- cide users' treatment and disposal prob- lems. The technical program included presentations by government research- ers and regulators, academia, industry experts, and individuals Involved in pes- ticide disposal and treatment. The workshop was sponsored by the following organizations: U.S. Environmental Protection Agency Office of Research and Development Risk Reduction Engineering Labora- tory Cincinnati, Ohio 45268 and Tennessee Valley Authority National Fertilizer and Environmen- tal Research Center Muscle Shoals, Alabama 35660 This Project Summary was devel- oped by EPA's Risk Reduction Engi- neering Laboratory, Cincinnati, OH, to announce key findings of the research project that is fully documented In a separate proceedings of the same title (see Project Report ordering Informa- tion at back). Aside from the technical presentations, the workshop allowed for some discussion among the participants. Several issues/ concerns were discussed by the attend- ees. The two issues which caused the greatest concern were site remediation and regulatory framework. Discussions on site remediation were directed toward dealer sites. The focuses on the cleanup were both soils and ground- water contamination. The largest problems identified with dealer site cleanup were costs and issues of how clean is clean enough. It was noted that many dealers could go bankrupt if costs were high. Also, little remediation is being conducted be- cause dealers feel that regulators cannot give them cleanup levels that will hold true in the future. Regulatory framework is also of great concern. Discussion ensued regarding how to solve this problem. Suggestions included the following: 1) Prove technology first, then worry about the regulatory framework. 2) Regulatory framework needs to be looked at while technology is being developed—it can and does drive costs. 3) Policy people are not listening to re- search people. 4) Get the key players involved. Target state regulators since they are clos- est to the problem. Get the concerns and scientific information to the perti- nent regulatory people. Another topic of discussion was waste minimization and education. It was agreed that many pollution prevention ideas would significantly decrease the number of future problems involving pesticides. These waste minimization techniques were generally low-cost practical solutions to managing ^g> Printed on Recycled Paper ------- pesticides and pesticide wastes. It is im- portant that these ideas become common practices through education of appropriate users and dealers of pesticides.
