On November 22, 2017, the U.S. Environmental Protection Agency (EPA) announced it was releasing a preliminary list of chemical substances reported under the Toxic Substances Control Act (TSCA) Inventory Notification (Active-Inactive) rule that includes substances reported to EPA through November 10, 2017, and that it will be updated approximately once per month. EPA states that it is making this list available to help keep the stakeholder community informed of the status of reporting under the TSCA Inventory Notification (Active-Inactive) rule. EPA is providing the list in a downloadable, searchable spreadsheet. The total number of chemicals on the list is 10,730.

This total adds substantially to the 13,209 substances that appear on EPA’s list of substances exempt from Form A reporting. It is important to note that the new list is not an update to the list of interim active substances or to the list of substances exempt from Form A reporting; it is only a list of substances reported via Form A notices of activity through the specified date. The new list of substances reported by Form As will be useful to processors, allowing them to ensure that key substances are reported as active, but it does not relieve manufacturers or importers from the Form A reporting obligations of the rule.
