New EPA definition for “nano” could affect state of regulations

At an April 29 presentation to the Pesticide Programs Dialogue Committee in Washington, D.C. EPA’s William Jordan announced a new working definition of nanomaterials as “an ingredient that contains particles that have been intentionally produced to have at least one dimension that measures between approximately 1 and 100 nanometers.” In addition EPA is preparing a Federal Register Announcement due out in June which announces a new interpretation of FIFRA/regulations and proposes a new policy stating that the presence of a nanoscale material in a pesticide product is reportable under FIFRA section 6(a)(2) and applies to already registered products as well as products pending registration.
