The <br /> AF is a numerical value, set by DPR,of the relative amount of 1,3-D <br /> potentially present in the air near treated fields. The higher the AF value,the <br /> greater the proportion of the applied 1,3-D that may escape into the air.AF <br /> values are based on the geographic location,month, and application method. <br /> Annual use For all townships in California, except one (Merced township 7S/11E"),the <br /> limit for each use limit is 136,000 ATP per calendar year. <br /> township <br /> x Only for calendar year 2017,Merced township 7S/11E has a use limit of <br /> 115,000 ATP. After 2017,the cap for township 7S/11E reverts to 136,000 <br /> ATP. <br /> Dow AgroSciences LLC (DAS) or the DAS's contractor is responsible for <br /> tracking, reporting,and ensuring township use limits are observed.The <br /> annual township use limit is fixed and cannot be exceeded(i.e., cannot <br /> "bank"and roll over unused allotted ATP for later use). <br /> J-3 <br /> Appendix J— 1,3-Dichloropropene(Field Fumigant) <br /> Recommended Permit Conditions(Rev. 1-17) <br />
