This document provides the reasons for EPA's response to a petition it received under the Toxic Substances Control Act (TSCA). The TSCA section 21 petition was received from Earthjustice, Natural Resources Defense Council, Toxic-Free Future, Safer Chemicals, Healthy Families, BlueGreen Alliance, and Environmental Health Strategy Center on January 6, 2017. The petitioners requested that EPA issue an order under TSCA section 4, requiring that testing be conducted by manufacturers and processors of chlorinated phosphate esters ("CPE"). The CPE Cluster is composed of tris(2-chloroethyl) phosphate ("TCEP") (CAS No. 115-96-8), 2-propanol, 1-chloro-, phosphate ("TCPP") (CAS No. 13674-84-5), and 2-propanol, 1,3- dichloro-, phosphate ("TDCPP") (CAS No. 13674-87-8). After careful consideration, EPA denied the TSCA section 21 petition for the reasons discussed in this document.
