## Abstract

Under the Toxic Substances Control Act (TSCA), EPA has issued a testing consent order (Order) that incorporates an enforceable consent agreement (ECA) with Dow Corning Corporation, Evonik Corporation, Momentive Performance Materials USA Inc., Shin-Etsu Silicones of America, Inc., and Wacker Chemical Corporation (the Companies). The Companies have agreed to certain environmental testing that will be used by EPA to characterize sources and pathways of release of octamethylcyclotetrasiloxane (D4) to the environment and resulting exposures of aquatic and sediment dwelling organisms to D4, contributing to the Agency's efforts to understand potential environmental effects of D4. This document revises the listing for D4 in the table of testing consent orders for substances and mixtures with Chemical Abstract Service (CAS) Registry Numbers. This document announces the ECA and the Order that incorporates the ECA for this testing, and summarizes the terms of the ECA. As a result of this action, exporters of D4, CAS No. 556-67-2, including persons who do not sign the ECA, are subject to TSCA export notification requirements.
