Chloropicrin and Chloropicrin in Combination with Other <br /> ' Products (Field Fumigant) Interim Recommended Permit <br /> Conditions, Continued <br /> 1 <br /> Tree hole The maximum number of tree holes and acreage allowed to be treated for any <br /> limitations site(entire orchard)in a 24-hour period are: <br /> ' • 50 holes per acre in no more than 40 acres <br /> a 75 holes per acre in no more than 10 acres <br /> e 100 holes per acre in no more than 5 acres <br /> ' • 200 holes in no more than 1 acre <br /> If any site is fumigated more than once (e.g., sequential applications within a <br /> ' single orchard),at least 36 hours must elapse between fumigations.Elapsed <br /> time is measured fiom the time the earlier application is complete until the <br /> start of the later application. <br /> ' These limits assume that the tree holes are evenly distributed across the site, <br /> and may not provide adequate protection for tree holes that are unevenly <br /> distributed.To prevent bunching of tree holes,DPR recommends the <br /> following spacing between fumigated tree holes: <br /> O At least 30 feet for 50 holes per acre in no more than 40 acres <br /> • At least 25 feet for 75 holes per acre in no more than 10 acres <br /> ' • At least 20 feet for 100 holes per acre in no more than 5 acres <br /> C At least 15 feet for 200 holes in no more than 1 acre <br /> ' This recommended minimum spacing does not need to be achieved for each <br /> tree hole,but should be achieved for the majority of tree holes,particularly <br /> near the borders of an orchard. <br /> ' A separation of 51 feet between tree holes(i.e.,minimum distance for no <br /> overlapping buffer zones)is Iikely insufficient separation between application <br /> blocks for this permit condition. The required buffer zone of 25 feet may not <br /> ' provide adequate protection if multiple application blocks within a single <br /> orchard(or adjacent orchards)are fumigated with less than 36-hour <br /> separation, CAC staff should consult with DPR before allowing these types of <br /> ' fumigations. <br /> For products containing methyl bromide and chloropicrin,the application is <br /> ' limited to 1 acre. <br /> Continued an next page <br /> 14 <br /> ' Appendix K—Chloropicrin and Chloropicrin in Combhiation Nvith Other Products <br /> (Field Fumigant)Interim Recommended Permit Conditions(Rev.1-17) <br /> 1 <br />
