On November 27, 2020, the U.S. Environmental Protection Agency (EPA) announced the availability of the draft scope documents for the manufacturer-requested risk evaluations of diisodecyl phthalate (DIDP) and diisononyl phthalate (DINP). 85 Fed. Reg. 76077; 85 Fed. Reg. 76072. EPA notes in its November 25, 2020, announcement that both DIDP and DINP “belong to a family of chemicals called phthalates and are commonly used as plasticizers in the production of plastic and plastic coating to increase flexibility.” EPA seeks public input on the draft scope documents, which include the conditions of use to be included in the risk evaluations, the next step in the process. Comments on the draft scope documents are due January 11, 2021. EPA will use public comments to inform the final scope documents.
EPA states that it generally conducts manufacturer-requested risk evaluations in the same manner as other risk evaluations conducted under the Toxic Substances Control Act (TSCA). For more information, please read the full memorandum.
