• At least 15 feet for 200 holes in no more than 1 acre This recommended minimum spacing does not need to be achieved for each tree hole but should be achieved for the majority of tree holes, particularly near the borders of an orchard. A separation of 51 feet between tree holes (i.e., minimum distance for no overlapping buffer zones) is likely insufficient separation between application blocks for this permit condition. The required buffer zone of 25 feet may not provide adequate protection if multiple application blocks within a single orchard (or adjacent orchards) are fumigated with less than 36-hour separation. CAC staff should consult with DPR before allowing these types of fumigations. For products containing methyl bromide and chloropicrin, the application is limited to 1 acre. Overlapping If buffer zones for two or more applications overlap within 36 hours from the buffer zones time the earlier application is complete until the start of the later application, certain restrictions apply based on the type of tarpaulin used (if any). Labels require a minimum of 12 hours to elapse from the time the earlier application(s) is complete until the start of the later application. An application block is the area of a field treated in a 24-hour period. The following are additional restrictions when application block buffer zones overlap within the first 36 hours: Scenario 1: All application blocks use TIF. TIF conditions: • Combined TIF acreage shall not exceed 60 acres. • Buffer distance for each TIF block shall be based on individual method,application rate, and acres. Scenario 1 example: Coastal county,two applications,both blocks use TIF. Block 1: Block 2: •TIF •TIF • Broadcast shank •Drip • 200 lbs.Al/ac 41150 lbs. Al/ac • 10 ac .20 ac Buffer zone determination: Combined TIF acreage is less than 60 ac(10+20=30).
