A-A1 <br /> APPENDIX A <br /> AMENDMENT TO WATER QUALITY CONTROL PLAN <br /> PESTICIDE RINSE WATERS <br /> PROBLEM STATEMENT <br /> Rinse waters containing small amounts of pesticides originate from air and <br /> ground applicators who apply agricultural chemicals throughout the Central <br /> Valley. Rinsing of equipment is required when switching compounds which are <br /> incompatible for registered use on the succeeding crop to be treated or, because <br /> of an incompatibility between the two compounds. . During Phase I of 208 <br /> planning, an evaluation of current management practices for handling rinse water <br /> and their effect on water quality was initiated. 1. ,2. , results of this <br /> evaluation revealed that some practices for handling pesticide rinse waters are <br /> not adequate to protect water quality and that ground and surface waters at <br /> sites within the Central Valley may be threatened. <br /> ACTION PLAN <br /> There are 200 sites within the Central Valley where pesticide rinse waters are <br /> produced and must be managed to prevent water quality contamination. The <br /> following are steps to be taken and guidelines to be followed in the Pesticide <br /> Rinse Water Management Program: <br /> 1. Regional Board staff, in cooperation with the Department of Food and <br /> Agriculture - Pesticide Use Enforcement Division and local Agricultural <br /> Commissioners , will inventory all facilities producing pesticide rinse <br /> water and determine the potential for surface and ground water contami- <br /> nation. This inventory will be accomplished by 30 June 1980. <br /> At inspected locations where rinse water originates, and there is an <br /> unreasonable risk of contamination of surface or ground water, operators <br /> shall meet the following guidelines: <br /> a. Prohibition of discharge of diluted pesticide rinse water to any <br /> surface or groundwater; <br /> 1'.
