This letter announces the availability of, and summarizes updates to, Volume 3, Restricted Materials and Permitting, of the Pesticide Use Enforcement Program Standards Compendium. Updates are enclosed and also 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.

Changes caused by the volatile organic compound (VOC) requirements necessitated a major reorganization to Appendix C. In order to minimize future changes to the page numbering, those sections least likely to have major changes have been moved to the front of this section, while sections most likely to have changes have been moved to the back. We apologize for the inconvenience this may cause.

To print the revised portions of the manual, select from the enclosures or go to It is recommended the sections be printed back-to-back where applicable. Remove the old sections from the manual and insert the new sections:
