2070-AK73 202304 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 the Toxic Substances Control Act (TSCA)

This proposed rulemaking will address the unreasonable risk of injury to health presented by 1-bromopropane (1-BP) under its conditions of use as documented in EPA’s 2020 risk evaluation and 2022 revised risk determination. Section 6(a) of the Toxic Substances Control Act (TSCA) requires EPA address by rule any unreasonable risk identified in a TSCA risk evaluation and apply requirements to the extent necessary so the chemical no longer presents unreasonable risk. EPA's risk evaluation for 1-BP, describing the conditions of use, is in docket EPA-HQ-OPPT-2019-0235, with the 2022 unreasonable risk determination and additional materials in docket EPA-HQ-OPPT-2016-0741.
