The 1990 Supplement to EPA's 1985 Edition of the Toxic Substances Control Act (TSCA) Chemical Substance Inventory covers approximately 5,000 substances that have been added to the Inventory since the 1985 publication. However, substances that were added to the Inventory after February 1, 1990 are not included in the publication. Together, the 1985 Edition and the 1990 Supplement constitute a revised Inventory representing a total of 68,000 chemical substances. From a regulatory standpoint, the Inventory defines what chemical substances are existing in U.S. commerce for purposes of implementing TSCA. Substances that are not included on the Inventory are considered new by EPA and are subject to the Premanufacture Notification (PMN) requirements under Section 5(a) of TSCA.
