Summary

This document announces the availability of EPA's response to an August 7, 2019 petition it received under section 21 of the Toxic Substances Control Act (TSCA) from Public Employees for Environmental Responsibility (PEER). PEER petitioned EPA to prohibit the use of hydrofluoric acid in manufacturing processes at oil refineries under TSCA section 6(a) and require a phase-out of use at such facilities within two years. After careful consideration, EPA has denied the TSCA section 21 petition for the reasons discussed in this document.
