• Restricted Materials and Permitting – Table of Contents
• Appendix C, DPR Recommended Permit Conditions – Added Section C.8, Recommended Permit Conditions for aluminum and magnesium phosphide for burrowing rodent control. In 2010, the U.S. EPA required additional use restrictions, including a 100 foot distance from structures, in response to two deaths in Utah. (See ENF Letter 11-11 at www.cdpr.ca.gov/docs/county/cacltrs/penfltrs/penf2011/2011011.htm. DPR is recommending these permit conditions because there are products in the channels of trade which don’t bear the new labeling restrictions to protect human health.

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

Sincerely,
