EPA announced a final rule to require comprehensive reporting on all six fiber types of asbestos as the agency continues its work to address exposure to this known carcinogen and strengthen the evidence that will be used to further protect people from this dangerous chemical. The rule, issued under section 8(a) of the Toxic Substances Control Act (TSCA), requires asbestos manufacturers (including importers) and processors to report certain use and exposure information from the past four years, including information on asbestos-containing products (including as an impurity). Under the reporting rule, manufacturers (including importers) or processors of asbestos between 2019 and 2022 with annual sales above $500,000 in any of those years are required to report exposure-related information, including quantities of asbestos manufactured or processed, types of use, and employee data. Importantly, the rule also covers asbestos-containing products (including products that contain asbestos as an impurity) and asbestos that is present as a component of a mixture. Manufacturers (including importers) and processors subject to the rule will have nine months following the effective date of the final rule to collect and submit all required information to EPA.
