Summary

On April 15, 2008, EPA reregistration team members from Antimicrobials
Division met with representatives from the Wood Preservative Science
Council regarding EPA’s upcoming reregistration eligibility decision
(RED) for wood preservative uses of chromated copper arsenate (CCA).  

Discussions focused ways to improve label clarity and minimize diversion
(i.e., using legally treated wood for non-registered uses).  The WPSC
proposed limiting label use site information to permitted uses by the
following categories: marine, highway, composite, laminates, plywood,
piles, posts, poles, and miscellaneous.  These categories would further
be broken down by commodity (e.g., shakes and shingles) and use
description linked to the American Wood Preservatives Association
standards (e.g., 3B).  The WPSC is also developing a “guidance
document” geared toward users unfamiliar with the wood treating
industry.  WPSC anticipates that this guidance document would be
particularly useful to enforcement personnel.  It is yet to be decided
whether this document will be informational or incorporated by reference
as part of the labeling.

The WPSC and EPA will continue to discuss label and labeling
improvements related to the reregistration eligibility decision.
