EPA Publishes Final Reporting Requirements for TSCA Mercury Inventory
On June 22, 2018, the U.S. Environmental Protection Agency published a prepublication version of the final rule regarding reporting requirements for applicable persons to provide information to assist in the preparation of an “inventory of mercury supply, use, and trade in the United States,” where “mercury” is defined as “elemental mercury” and “a mercury compound” (mercury). The final rule applies to any person who manufactures (including imports) mercury or mercury-added products, or otherwise intentionally uses mercury in a manufacturing process (including processes traditionally not subject to the Toxic Substances Control Act (TSCA), such as for the manufacture of pharmaceuticals and pesticides). EPA will use data from the 2018 reporting year for the 2020 mercury inventory. The 2018 reporting year is from January 1, 2018, to December 31, 2018, and the submission deadline for the 2018 reporting year is July 1, 2019. The final rule will be effective 60 days after publication in the Federal Register, which is scheduled for June 27, 2018.
The reporting requirements include activities that are established TSCA terms, including manufacture, import, distribution in commerce, storage, and export. EPA notes that the reporting requirements also apply to the otherwise intentional use of mercury in a manufacturing process. Persons who manufacture (including import) mercury or mercury-added products, or otherwise intentionally use mercury in a manufacturing process, are required to report amounts of mercury in pounds (lbs.) used in such activities during a designated reporting year. Reporters must also identify specific mercury compounds, mercury-added products, manufacturing processes, and how mercury is used in manufacturing processes, as applicable, from preselected lists. For certain activities, reporters must provide additional, contextual data.
The final reporting requirements do not apply to: (1) persons who do not first manufacture, import, or otherwise intentionally use mercury; (2) persons who only generate, handle, or manage mercury-containing waste; (3) persons who only manufacture mercury as an impurity; and (4) persons engaged in activities involving mercury not with the purpose of obtaining an immediate or eventual commercial advantage. Within the category of persons who must report, there are certain persons who are not required to provide specific data elements. To avoid reporting that is unnecessary or duplicative, the final rule includes certain exemptions for persons who already report for mercury and mercury-added products to the TSCA Section 8(a) Chemical Data Reporting (CDR) rule and the Interstate Mercury Education and Reduction Clearinghouse (IMERC) Mercury-Added Products Database, respectively.
More detail is provided in our June 25, 2018, memorandum regarding the provisions of the final rule, including EPA’s rationale for fulfilling specific statutory provisions and terms. While the final rule includes summaries of public comments received and EPA’s responses and determinations, EPA notes that some of these issues are discussed in greater detail in its Response to Comments. EPA states that its Response to Comments will be available in Docket EPA-HQ-OPPT-2017-0421, although it is not there at this time.
