On August 17, 2017, the U.S. Environmental Protection Agency (EPA) submitted a proposed rule regarding reporting requirements for a mercury inventory to the Office of Management and Budget (OMB).  The proposed rule would establish reporting deadline(s) and information requirements for the purpose of assisting EPA’s periodic update and publication of the inventory of mercury supply, use, and trade in the U.S.  As required under the Frank R. Lautenberg Chemical Safety for the 21st Century Act, EPA must “carry out and publish in the Federal Register an inventory of mercury supply, use, and trade” in the U.S.  The Lautenberg Act defines mercury as “elemental mercury” or “a mercury compound.”  The inventory was to be published no later than April 1, 2017, and every three years thereafter, as supported by a rule authorized in the Lautenberg Act.  As reported in our March 29, 2017, blog item, EPA published an initial inventory report on March 29, 2017.  For subsequent inventories, EPA is authorized to promulgate a rule to “assist in the preparation of the inventory” so that “any person who manufactures mercury or mercury-added products or otherwise intentionally uses mercury in a manufacturing process shall make periodic reports to the Administrator, at such time and including such information as the Administrator shall determine.”  EPA expects future triennial inventories of mercury supply, use, and trade to include data collected directly from such persons.  In future inventories, EPA also will “identify any manufacturing processes or products that intentionally add mercury; and . . . recommend actions, including proposed revisions of Federal law or regulations, to achieve further reductions in mercury use.”  EPA must promulgate a final rule by June 22, 2018.

On March 29, 2017, the U.S. Environmental Protection Agency (EPA) issued in the Federal Register a notice releasing its initial inventory report of mercury supply, use, and trade in the United States pursuant to Section 8(b)(9)(10) of the amended Toxic Substances Control Act (TSCA).  Specifically, the report is a “compilation of readily available, previously published data on the supply, use and trade elementary mercury and mercury compounds,” and its purpose is to “identify any manufacturing processes or products that intentionally add mercury.”  The report itself is available in Docket ID EPA-HQ-OPPT-2017-0127-002 on  The notice states that EPA is not soliciting comments on this report.

The report states that it is focused on commodity mercury, as opposed to mercury that is handled and discarded as waste, and that in some cases the information is outdated.  The report is organized in three parts:

  • Introduction, which includes U.S. laws affecting supply and trade of Mercury; and sources of information;
  • Elemental mercury, which includes supply of elemental mercury, sources of supply, use of elemental mercury (including mercury-added products and manufacturing processes), and trade of elemental mercury; and
  • Mercury compounds, which includes supply, use, and trade of Mercury compounds.
