“The U.S. Environmental Protection Agency (EPA) published a Federal Register notice on November 12, 2019, announcing the availability of its response to a petition it received under Section 21 of the Toxic Substances Control Act (TSCA) from Public Employees for Environmental Responsibility (PEER). 84 Fed. Reg. 60986. As reported in our August 23, 2019, blog item, PEER petitioned EPA under TSCA Section 21 to prohibit the use of hydrofluoric acid in manufacturing processes at oil refineries under TSCA Section 6(a) and under the Administrative Procedure Act (APA) to take the same action pursuant to Section 112 of the Clean Air Act (CAA).
PEER petitioned EPA to prohibit the use of hydrofluoric acid in manufacturing processes at oil refineries and require a phase-out of use at such facilities within two years. EPA states that after “careful consideration,” it has denied the Section 21 petition. EPA notes that the Federal Register notice specifically addresses only the TSCA Section 21 petition, not the petition submitted under the APA. EPA is denying the petition “based on the petition’s lack of sufficient facts establishing that it is necessary for the Agency to issue a rule under TSCA section 6(a).” According to EPA, to grant a petition for a TSCA Section 6(a) rulemaking, a petition must provide facts establishing that the requested rulemaking is necessary. Those facts need to be ‘sufficiently clear and robust for EPA to be able to conclude, within 90 days of filing the petition, that the chemical presents an unreasonable risk of injury to health or the environment and that issuance of a TSCA section 6(a) rule is the appropriate response to the petition.'”
