Judah Prero Quoted in Bloomberg Law on EPA Chemical Policy Signals

Judah Prero, Arnold & Porter Environmental counsel and former Assistant State Attorney General at the Maryland Department of the Environment, was recently quoted in the Bloomberg Law article, “EPA’s Paused Chemical Lawsuits Offer Path to Regulatory Overhaul.” The article examines how the Environmental Protection Agency (EPA) is signaling potential shifts in chemical policy through litigation over Biden-era regulations and notes that tracking the positions the agency takes and the requests it makes in ongoing cases may offer insight into the policies the Trump Administration is working toward.

Judah explained that ongoing court challenges to several Toxic Substances Control Act (TSCA) rules — including those addressing risk determinations, worker protections, and chemical exposure limits — are providing a window into how the agency may revise its regulatory approach while litigation proceeds.

Among the potential changes Judah highlighted is uncertainty about how EPA may regulate workplace exposures, including the possibility of moving away from reliance on Integrated Risk Information System (IRIS) toxicity values for certain chemicals. He also discussed how the EPA may interpret TSCA as allowing the agency to exclude certain uses and exposure pathways from risk evaluations and, in some cases, defer regulation to other EPA programs or to other federal agencies.
