This letter announces the availability of, and summarizes updates to Pesticide Use Enforcement Program Standards Compendium Volume 3, Restricted Materials and Permitting. Updates are enclosed and will be available online at the link provided below. Please have your staff begin using these updates as soon as possible. Hard copies of the updates will not be distributed.

The attached revised interim recommended permit conditions mitigate hazards associated with offsite movement of chloropicrin and apply to all chloropicrin applications when used as a field fumigant.

This update includes: 1) only buffer zone credit allowed is the 60% credit for DPR-approved TIF (totally impermeable films) tarpaulins; 2) adds strip applications to Tables 9a, 9b, 10a, and 10b; and 3) revises buffer zone tables only for Table 9b and Table 10a where the minimum buffer zone has been corrected to 100 feet.

To print the revised portions of the manual, select from the enclosures or go to www.cdpr.ca.gov/docs/enforce/compend/vol_3/rstrct_mat.htm. It is recommended the sections be printed back-to-back, where applicable. For best results, print appendix separately. Remove the old section from the manual and insert the new section:

• Appendix K,Chloropicrin and Chloropicrin in Combination with Other Products (Field Fumigant) Interim Recommended Permit Conditions
  • 60% buffer zone credit only for DPR-approved list of California-specific TIF tarpaulins
  • Revised buffer zone tables for certain application methods
  • Revised minimum buffer zones for two specific application methods

If you have any questions, please contact the Enforcement Branch Liaison assigned to your county.

Sincerely,
