EPA throws in the towel on policing air pollution from factory farms
I've watched the EPA dance around factory farm emissions for years, and this feels like the end of the dance. The agency's enforcement record on CAFOs was already thin, scattered consent decrees and the occasional penalty, but an explicit retreat tells communities the federal door is basically closed. What's left is a patchwork of state air boards, many of which are underfunded or friendly to agriculture, and that's a poor substitute for a national baseline.
The interesting part is what this does to the incentive structure. If the threat of a Clean Air Act case disappears, operators have little reason to install covers on manure lagoons or invest in methane capture beyond what economics already justify. I'd want to see whether state attorneys general pick up the slack, because that's where the real action tends to land when Washington steps back.
I also wonder if this is a quiet acknowledgment of reality. The EPA has struggled for decades to measure emissions from these sites, and the science of attributing a specific plume to a specific farm has never been clean. Retreating might be easier than defending a rule you can't enforce credibly. Still, the people downwind of a large operation don't care about the agency's measurement problems, and they're the ones left holding the bag.
