On August 31, 2021, the U.S. Environmental Protection Agency (EPA) announced the availability of the final scope documents for the manufacturer-requested risk evaluations (MRRE) of di-isodecyl phthalate (DIDP) and diisononyl phthalate (DINP). 86 Fed. Reg. 48695; 86 Fed. Reg. 48693. The scope documents include the conditions of use, hazards, exposures, and the potentially exposed or susceptible subpopulations that EPA plans to consider in conducting the risk evaluations for DIDP and DINP. In its press release, EPA notes that the final scope documents reflect its policy changes on risk evaluations announced in June 2021. This includes plans to consider exposure pathways that may be regulated outside of TSCA, like air and water, and potential for exposures to fenceline communities.
