Inside EPA reports today that a "senior policy adviser for EPA’s Office of Pesticide Programs, said EPA would issue in June a long-awaited response to a 2008 activist petition asking the agency to regulate nanoscale silver under FIFRA." The article also mentions that EPA intends to define nanoscale ingredients for FIFRA purposes 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."
