On August 26, 2016, the Environmental Protection Agency (EPA) published in the Federal Register a notice [EPA-HQ-OPPT-2016-0411; FRL-9950-21] advising the public that, effective January 1, 2020, the Frank R. Lautenberg Chemical Safety for the 21st Century Act (the Act), which amended the Toxic Substances Control Act (TSCA). prohibits the export of: mercury (I) chloride or calomel; mercury (II) oxide; mercury (II) sulfate; mercury (II) nitrate; and cinnabar or mercury sulphide, unless those mercury compounds are exported to member countries of the Organization for Economic Co-operation and Development for environmentally sound disposal, on the condition that no mercury or mercury compounds so exported are to be recovered, recycled, or reclaimed for use, or directly reused, after such export.  EPA was directed by Congress to publish in the Federal Register a list of mercury compounds that are prohibited from export, not later than 90 days after the date of enactment of the Act. EPA is not soliciting comments on this notice.
