The U.S. Environmental Protection Agency today issued guidance materials for the recently-issued TSCA section 8(a) Nanotechnology Reporting and Recordkeeping Requirements Rule which becomes effective on August 14, 2017. This rule establishes one-time reporting and recordkeeping requirements for certain chemical substances when they are manufactured or processed at the nanoscale as described in the rule issued January 12, 2017.

The guidance reflects input received on draft guidance EPA issued in May 2017 and provides answers to questions the Agency has received from manufacturers (including importers) and processors of certain chemical substances when they are manufactured or processed at the nanoscale, as described in the final rule. EPA has incorporated public comments and included additional questions in the guidance.  We intend to update the guidance based on questions and input we receive.

If this general guidance does not answer those questions or other questions you have about the rule, please contact EPA and the Agency will answer these questions on a case-by-case basis.  EPA intends to add further questions/answers and update the guidance as warranted based on further questions we may receive. EPA's technical contact for this rule, Jim Alwood, can be reached at Alwood.jim**At_Symbol_Here**epa.gov.
