UPDATES TO VOLUME 3, RESTRICTED MATERIALS AND PERMITTING, PESTICIDE USE ENFORCEMENT PROGRAM STANDARDS COMPENDIUM: CHLOROPICRIN AND CHLOROPICRIN IN COMBINATION WITH OTHER PRODUCTS (FIELD FUMIGANT) INTERIM RECOMMENDED PERMIT CONDITIONS

This letter announces the availability of, and summarizes updates to, Volume 3, Restricted Materials and Permitting, one of eight volumes of the Pesticide Use Enforcement Program Standards Compendium. 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.

This letter supersedes the recommended permit conditions for all applications of chloropicrin field fumigations found in Enforcement letter ENF 12-21 (Amended) dated March 7, 2013. The revised interim recommended permit conditions (see attachment) mitigate hazards associated with offsite movement of chloropicrin and apply to all chloropicrin applications when used as a field fumigant. Buffer zone tables are specific to different application methods, with separate tables categorized by Coastal and Inland Counties.

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 each chapter and appendix separately. Remove the old sections from the manual and insert the new sections:

• Table of Contents
  • Updated page iii with the new title for Appendix K
• Appendix K (formerly Appendix C, Subsection C.7.4), Chloropicrin and Chloropicrin in Combination with Other Products (Field Fumigant) Interim Recommended Permit Conditions
  • Updated DPR recommended permit conditions
  • Adds buffer zone tables, categorized by Coastal Counties and Inland Counties

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