TSCA requires EPA to issue final risk evaluations for each of the 20 chemicals no later than December 20, 2022, but EPA is authorized to grant itself a one-time six month extension to June 20, 2023 if it needs more time to complete its risk evaluations.
EPA will also soon proceed with risk evaluations for two phthalates—di-isodecyl phthalate (DIDP) and di-isononyl phthalate (DINP)—at the request of industry stakeholders. Scoping documents for those chemicals have not yet been released, but companies should also keep them on their radars.
Links to each of the 20 final scoping documents, as well as non-exhaustive lists of common uses of each chemical, are provided below.
