II. What Action is the Agency Taking?

EPA has released on its website updates to the listing of inert ingredients permitted in pesticide products. The lists were last updated in 2004. The website address for the updated lists is​opprd001/​inerts/​lists.html.

EPA’s website now provides a list of inert ingredients permitted in pesticide products applied to non-food sites (e.g., ornamental plants, highway right-of-ways, rodent control, etc.). This list has been updated with new inert ingredients approved for use in non-food pesticide products since 2004. The website also provides directions for finding in the electronic Code of Federal Regulations (e-CFR) tolerances and tolerance exemptions for inert ingredients that may be used in pesticide products applied to food commodities. It is important to note that only inert ingredients with tolerances or tolerance exemptions found in the Code of Federal Regulations may be used in food-use pesticide products, and must be in accordance with the uses and limitations (if any).

The Agency’s website update includes a list of inert ingredients that may be used in minimum risk pesticides exempted under FIFRA Section 25(b). Stakeholders should now find it easier to locate 25(b)-eligible inert ingredients (called “4A” under an old EPA policy; see Pesticide Registration Notice 2000-6;​PR_​Notices).

In addition, EPA’s website is providing an easy way for stakeholders to find inert ingredients that are eligible for use under USDA’s National Organic Start Printed Page 73802Program (NOP). EPA’s website now provides access to a consolidated list of inert ingredients eligible for the NOP through links to USDA’s NOP website. In the past, stakeholders had to search the inert ingredient list on EPA’s website for NOP-eligible inert ingredients (i.e., inert ingredients considered to be “List 4” under an old policy). It is important to note that all matters of policy concerning the eligibility of inert ingredients for use in the NOP are determined by USDA. EPA’s role is to assist USDA by assuring that USDA’s policies are implemented with regard to organic claims made on registered pesticide product labeling.
