The Nickel Report

On May 3, 2023, EPA released its proposed risk management rule under Section 6(a) of the Toxic Substances Control Act (TSCA) to impose restrictions on the manufacture, import, processing, distribution, and use of methylene chloride, a widely-used solvent in a variety of consumer and commercial applications. This is the first risk management rule proposed by EPA since it issued revised risk determinations last year based on its new “whole chemical approach” and policy for assuming that personal protective equipment (PPE) is not used by workers. It also reflects a substantial expansion of the regulatory prohibitions applicable to a chemical that was already subject to TSCA risk management restrictions, albeit more limited ones, under EPA’s prior framework for risk management actions.

EPA is proposing to prohibit the manufacture, processing, and distribution in commerce of methylene chloride for consumer use; prohibit most industrial and commercial uses of methylene chloride; require a workplace chemical protection program (WCPP) for certain identified conditions of use that are allowed to continue; and provide certain time-limited, critical use exemptions under Section 6(g) of TSCA for uses of methylene chloride that would otherwise significantly disrupt national security and critical infrastructure. Stakeholders have until July 3, 2023 to comment on the proposed rule.
