Abstract

During scoping of this assessment EPA/OPPT identified a structurally related cluster of chlorinated phosphate ester used as flame retardant (CPE FR) chemicals, including tris(2-chloroethyl) phosphate (TCEP, CASRN 115-96-8), 2-Propanol, 1-chloro-, phosphate (TCPP, CASRN 13674-84-5), and 2-Propanol, 1,3-dichloro-, phosphate (TDCPP, CASRN 13674-87-8). This Problem Formulation Assessment describes the TSCA related uses that were evaluated for inclusion and exclusion in this assessment. This problem formulation includes the conceptual model and the analysis plan for evaluating those uses for these chlorinated phosphate ester flame retardants. This analysis plan of CPE TSCA flame retardant uses, also identified best available data and approaches for assessing exposures and hazards.
