• TSCA Chemical Substance Inventory Reporting Form C provides the chemical industry a method to submit requests to EPA’s OPPT for correcting misreported chemical identities of substances listed on the Inventory.

Shortly after the first Toxic Substances Control Act (TSCA) Inventory was published in 1979, the Environmental Protection Agency (EPA) determined that reported substances may have been unintentionally misidentified as a result of simple typographical errors, the misidentification of substances, or the lack of sufficient technical or analytical capabilities to characterize the exact chemical substances.

TSCA Chemical Substance Inventory Reporting Form C (EPA Form 7710-3C) provides the chemical industry with a method to submit requests to EPA’s Office of Pollution Prevention and Toxics (OPPT) for correcting misreported chemical identities of substances listed on the Inventory. Such requests pertain only to errors discovered in the original submissions to the Inventory when the Inventory was first established in 1979.

The correction mechanism allows the submitter to add the correct substance to the Inventory without having to file a premanufacture notice (PMN) under TSCA section 5. The correction mechanism ensures the accuracy of the Inventory without imposing an unreasonable burden on the chemical industry. Without the Inventory correction mechanism, a submitter would have to file a PMN to place the correct chemical substance on the Inventory whenever finding that the previously reported substance was misidentified.
