According to the Office of Management and Budget (OMB) website, on July 30, 2010, OMB received from the U.S. Environmental Protection Agency (EPA) a notice concerning “Pesticide Products Containing Nanoscale Materials.” No additional information regarding the notice is available on OMB’s website. During the April 29, 2010, meeting of EPA’s Pesticide Program Dialogue Committee (PPDC), William Jordan, Senior Policy Advisor, Office of Pesticide Programs (OPP), stated that EPA was in the process of preparing a Federal Register notice on nanomaterials and pesticide products. The notice will announce a new interpretation of Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 6(a)(2) regulations, that the presence of a nanoscale material is reportable under FIFRA Section 6(a)(2). This controversial interpretation would apply to already registered products, as well as products pending registration. In the same notice, EPA is expected also to memorialize OPP’s view that an active or inert ingredient would be considered “new” if it is a nanoscale material. The new policy would apply even when a non-nanoscale form of that same active or inert is already in a FIFRA-registered product. On June 25, 2010, the U.S. Government Accountability Office (GAO) issued a report entitled Nanotechnology: Nanomaterials Are Widely Used in Commerce, but EPA Faces Challenges in Regulating Risk, which recommends, among other actions, that EPA should complete its plan to clarify that nanoscale ingredients in already registered pesticides, as well as in those products for which registration is being sought, are to be reported to EPA and that EPA will consider nanoscale ingredients to be new. EPA responded that it agreed with GAO’s recommendation and is working on clarification of registrant’s responsibilities under FIFRA with respect to nanomaterials.
