Requests for Modification or Revocation of Toxic Substances Control Act Section 5 Significant New Use Notice Requirements; Revision to Notification Regulations

This direct final rule amends the procedures for requests for modification or revocation of Toxic Substances Control Act (TSCA) section 5 significant new use notification (SNUN) requirements by establishing electronic submission requirements. EPA issued a final rule in the Federal Register of January 6, 2010, introducing electronic reporting requirements for TSCA section 5 submissions and supporting documents. However, the regulatory text inadvertently did not include amendments to the reporting requirements for submissions of requests for modifications or revocations of SNUN requirements. This direct final rule includes the amendment that was originally intended by EPA.
