In an article published on January 12, 2017 by regulatory news provider Chemical Watch, editor David Stegon informed that the U.S. Environmental Protection Agency (EPA) has published its final rule on the reporting of nanoscale materials. The rule requires “one-time reporting for existing discrete forms of certain nanoscale materials, and a standing one-time reporting requirement for new discrete forms of certain nanoscale materials before those new forms are manufactured or processed.”

The rule applies to chemical substances that are 1) “solids at 25°C and standard atmospheric pressure;” 2) “manufactured or processed in a form where any particles, including aggregates and agglomerates, are in the size range of 1-100 nanometers (nm) in at least one dimension;” and 3) “manufactured or processed to exhibit one or more unique and novel properties.” The EPA noted that these parameters are for identifying chemical substances that are subject to the rule and do not establish a definition of nanomaterials. Excluded from the rule are substances “manufactured or processed in forms that contain less than 1% by weight of any particles, including aggregates and agglomerates, in the size range of 1-100 nm.”

The rule is issued under the Toxic Substances Control Act (TSCA), section 8(a), and will take effect on May 12, 2017 (120 days after publication in the Federal Register).
