Description EPA was expected to finalize a rule this year directing states to develop pesticide management plans for four restricted-use pesticides: atrazine, simizine, metolachlor, and alachlor. Under this rule, EPA-approved plans would be required to continue use of these pesticides in the state. The Washington State Department of Agriculture is the lead agency. The U.S. Geological Survey and the Washington State Department of Ecology tested the feasibility of using EPA’s Pesticide Root Zone Model (PRZM2) model and a Geographic Information System (GIS) to screen for susceptibility on a regional scale. Ecology ran the model and mapped the results. The USGS has completed a review and evaluation comparing model results to observations and data obtained during the National Water Quality Assessment (NAWQA) study, which will be published in a separate report.
