As the lead agency for the implementation of Proposition 65, the Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency intends to list the chemicals, Carbaryl (CAS No. 63-25-2) and Spirodiclofen (CAS No. 148477-71-8) as known to the State to cause cancer, pursuant to this administrative mechanism.

Relevant information related to the possible listing of Carbaryl and Spirodiclofen was requested in a notice published in the California Regulatory Notice Register on December 5, 2008 (Register 2008, No. 49-Z). OEHHA received and responded to public comments.

OEHHA has determined that Carbaryl meets the regulatory criteria for listing based on the findings of the U.S. EPA (U.S. EPA, 2002; 2007a; 2007b) and Spirodiclofen meets the criteria for listing based on the findings of the U.S. EPA (U.S. EPA, 2004). OEHHA is therefore issuing this notice of intent to list Carbaryl and Spirodiclofen under Proposition 65.

Tectran used Nexreg for preparation of our MSDS and label for new Pendilube product launch. We found Mike Moffatt to be very helpful and thorough. We knew of most of the regulations that we were required to meet but with his help and document preparation we were able to have the confidence that we were covering all the required regulations that impacted our product.
