Court Struck Down EPA Ban on Methylene Chloride
The ruling mandates a secondary review of the chemical's risks, delaying the prohibition of commercial use.

Should federal regulators prioritize public health safety over the efficiency needs of industrial businesses?
In September 2026, the U.S. Court of Appeals for the Fifth Circuit invalidated the 2024 EPA rule that prohibited the commercial use of methylene chloride. This judicial decision forces the EPA to re-evaluate the unreasonable health risks associated with the chemical.
Why it matters
The ruling creates regulatory uncertainty for industrial applications of methylene chloride, a solvent valued for its rapid performance in paint strippers and sealants. It marks a significant legal obstacle for the EPA as it attempts to mitigate health risks previously linked to the substance.
Since 1980, the EPA has recorded 88 deaths resulting from acute methylene chloride exposure. The chemical remains in use for paint strippers, sealants, and spot removers while the agency conducts its court-ordered secondary review.
The players
Environmental Protection Agency
The federal regulatory body responsible for developing and enforcing environmental protection standards and chemical safety rules.
U.S. Court of Appeals for the Fifth Circuit
The federal appellate court with jurisdiction over the appeal brought by industry representatives against the EPA.
Joshua Atkins
An individual whose death from methylene chloride inhalation represents the acute risks of the chemical.
The details
Methylene chloride, also known as dichloromethane, is a volatile chemical solvent used in industrial settings to quickly strip paint or remove sealants from surfaces. Industry petitioners successfully argued against the EPA's 2024 ban, resulting in a court order requiring the agency to redo its analysis of the unreasonable risk posed by the substance. While commercial restrictions are halted, the 2019 EPA prohibition on consumer-level purchases of the solvent remains active.
Timeline
Since 1980, 88 deaths have been linked to acute methylene chloride exposure.
In 2018, Joshua Atkins died from methylene chloride inhalation.
In 2019, the EPA enacted a ban on consumer purchases of methylene chloride.
In 2024, the EPA issued a ban on the commercial use of methylene chloride.
In September 2026, the Fifth Circuit Court struck down the commercial ban.
The Tech Race
This ruling represents a significant legal challenge to the implementation of the EPA's Toxic Substances Control Act risk evaluation process, mirroring prior industry pushback against agency chemical bans. The decision mandates that the EPA restart its assessment process under the existing framework, effectively stalling the agency's current enforcement timeline.
While the 2019 ban on consumer-level purchases of methylene chloride remains in effect, commercial users and industries will continue to utilize the solvent until the EPA completes its new review. This means that current industrial workflows requiring rapid-action paint strippers will see no immediate changes to availability or product access.
The takeaway
The court's decision highlights the ongoing tension between industrial chemical utility and federal health regulation. Observers should monitor the EPA's official docket for the announcement of a new risk-mitigation strategy, which will determine the long-term future of this solvent.
What happens next
The EPA is expected to conduct a further review of the chemical's risks, a process that may take several years to reach a new ruling.
