On December 22, 2017, the U.S. Environmental Protection Agency (EPA) sent to the Office of Management and Budget (OMB) a proposed rule establishing fees on certain submissions under amended Toxic Substances Control Act (TSCA) Sections 4, 5, and 6. EPA has indicated that it expects to propose the rule in the early part of the New Year: EPA’s regulatory agenda lists February 2018 for the proposed rule and September 2018 for the final rule.
