2070-AK73 202210 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2070 Office of Chemical Safety and Pollution Prevention OCSPP 2000 Environmental Protection Agency EPA 1-Bromopropane; Rulemaking Under Section 6(a) of the Toxic Substances Control Act (TSCA)

The proposed rulemaking will address the unreasonable risk of injury to health identified in the final risk evaluation for 1-bromopropane (1-BP). Section 6(a) of the Toxic Substances Control Act (TSCA) requires EPA to eliminate unreasonable risks of injury to health or the environment that the Administrator has determined in a TSCA section 6(b) risk evaluation are presented by a chemical substance under the conditions of use. EPA's risk evaluation for 1-bromopropane, describing the conditions of use and presenting EPA's determinations of unreasonable risk, is in docket EPA-HQ-OPPT-2019-0235, with additional information in docket EPA-HQ-OPPT-2016-0741.

This rulemaking is needed to address the unreasonable risks of 1-bromopropane that were identified in a risk evaluation completed under TSCA section 6(b). EPA reviewed the exposures and hazards of 1-bromopropane, the magnitude of risk, exposed populations, severity of the hazard, uncertainties, and other factors. EPA sought input from the public and peer reviewers as required by TSCA and associated regulations.

In accordance with TSCA section 6(a), if EPA determines in a final risk evaluation completed under TSCA 6(b) that the manufacture, processing, distribution in commerce, use, or disposal of a chemical substance or mixture, or that any combination of such activities, presents an unreasonable risk of injury to health or the environment, the Agency must issue regulations requiring one or more of the following actions to the extent necessary so that the chemical substance no longer presents an unreasonable risk: (1) Prohibit or otherwise restrict manufacture, processing, or distribution in commerce of the substance, or limit the amount of the substance which may be manufactured, processed, or distributed in commerce; (2) Prohibit or otherwise restrict manufacture, processing, or distribution in commerce of the substance for a particular use or for a particular use above a set concentration, or limit the amount of the substance which may be manufactured, processed, or distributed in commerce for a particular use or for a particular use above a set concentration; (3) Require minimum warnings and instructions with respect to use, distribution in commerce, or disposal; (4) Require recordkeeping or testing by manufacturers or processors; (5) Prohibit or regulate any manner or method of commercial use; (6) Prohibit or regulate any manner or method of disposal for commercial purposes; and/or (7) Direct manufacturers or processors to give notice of the unreasonable risk to distributors, other persons, and the public and replace or repurchase the substance.

TSCA section 6(a) requires EPA to address by rule chemical substances that the Agency determines present unreasonable risk upon completion of a final risk evaluation. As required under TSCA section 6(c), EPA will consider one or more primary alternative regulatory actions as part of the development of a proposed rule.

EPA will prepare a regulatory impact analysis as the Agency develops the proposed rule.

As EPA determined in the TSCA section 6(b) risk evaluation, 1-bromopropane presents unreasonable risks to human health. EPA must issue risk management requirements so that this chemical substance no longer presents an unreasonable risk.
