Management Practice Options for Leaching GWPAs (Excluding Engineered Rights of Way)

Select one of the following four options:

   (1) The permittee shall not apply any irrigation water to the treated area for six months following application of the pesticide; or

   (2) The permittee shall apply the pesticide to the planting bed or the berm above the level of irrigation water in the furrow or basin for six months following application of the pesticide; or

   (3) Irrigation water applied to the treated area shall be managed so that the ratio of the amount of irrigation water applied divided by the net irrigation requirement is 1.33 or less for six months following application of the pesticide; or

   (4) An alternative management practice or pesticide approved by the Director as follows (check with the County Agricultural Commissioner to see if either of these apply):

         (a) Upon written request, the Director may evaluate and approve use of alternative mitigation measures that are based on scientific data demonstrating their effectiveness in reducing movement of pesticides to ground water; or

         (b) Upon written request, the Director may make a determination to allow the interim use of a pesticide containing a chemical listed in section 6800(a) within a leaching ground water protection area, for a period not to exceed three years. The Director's determination shall be based on evidence that the available mitigation measures are not feasible for a specific crop or site, and that there are no feasible alternatives for the specific crop or site. The formal request shall include a study protocol(s) that is acceptable to the Director to develop feasible alternatives or alternate mitigation measures.
