Ninth Circuit tells EPA to redo its rulemaking for toxic flame retardant

The Ninth Circuit Court of Appeals has ordered the Environmental Protection Agency to redo its rulemaking process regarding Decabromodiphenyl Ether (DecaBDE), a toxic flame retardant found in recycled products. The decision came in a challenge brought by environmental groups and the Yurok Tribe, both of which opposed the EPA's determination not to regulate the chemical's exposure.

The court found the EPA's decision-making process deficient and remanded the matter for further agency action. The Ninth Circuit did not specify what regulatory path the EPA must take, but the ruling effectively invalidates the agency's prior determination that DecaBDE exposure in recycled materials did not warrant federal regulation under the Toxic Substances Control Act (TSCA).

DecaBDE functions as a flame retardant in furniture, carpets, and electronics. When these products enter the recycling stream, the chemical persists in recycled materials and can leach into the environment and human bodies. The Yurok Tribe and environmental groups argued the EPA failed to adequately consider the health risks, particularly to vulnerable populations and tribal communities.

The panel's decision reflects ongoing tension between industry interests and environmental protection advocates. Manufacturers of recycled materials have generally resisted strict DecaBDE regulation, citing compliance costs and supply chain disruption. Environmental groups contend the chemical poses documented neurotoxicity risks and bioaccumulates in ecosystems.

The EPA now faces a decision: impose regulations limiting DecaBDE in recycled products, issue a risk determination that opens the door to future regulation, or mount a more detailed justification for non-regulation that satisfies the Ninth Circuit's procedural concerns. The agency's response will reshape regulatory frameworks across the recycling industry.

This ruling represents a partial victory for environmental plaintiffs, though it stops short of mandating specific regulatory outcomes. The practical effect depends entirely on how aggress
