On December 19, 2017, the U.S. Environmental Protection Agency (EPA) is scheduled to publish in the Federal Register a notice extending the comment period for the proposed rule on reporting requirements for the Toxic Substances Control Act (TSCA) mercury inventory for 16 days, from December 26, 2017, to January 11, 2018. The notice states that “EPA received requests to extend the comment period and believes it is appropriate to do so … to give stakeholders additional time to assess the impacts of the proposal, review technical documents in the docket, and prepare comments. The 2016 amendments TSCA require EPA to establish periodic mercury reporting requirements for any person that manufactures mercury or mercury-added products or otherwise intentionally uses mercury in a manufacturing process to assist in the development of an inventory of mercury and other recommended actions. EPA’s proposed rule, issued on October 26, 2017 (82 Fed. Reg. 49564), specifically requires reporting on the manufacture, import, distribution in commerce, storage, and export of mercury.
