TSCA Inventory Equivalency Determinations for Certain Class 2 Substances; TSCA Section 21 Petition; Reasons for Agency Response

This document announces the availability of EPA's response to a petition it received under the Toxic Substances Control Act (TSCA). The TSCA section 21 petition was received from the Biobased and Renewable Products Advocacy Group (BRAG) on October 7, 2015. The petitioner requested EPA to promulgate a rule pursuant to TSCA section 8 that would ``establish a process to amend the list of natural sources of oil and fat in the `Soap and Detergent Association' (SDA) nomenclature system by considering the chemical equivalency of additional natural sources.'' After careful consideration, EPA denied the TSCA section 21 petition for the reasons discussed in this document.
