EPA considers tougher regulation of livestock farm pollution

The U.S. Environmental Protection Agency says it will study whether to toughen regulation of large livestock farms that release manure and other pollutants into waterways.

EPA has not revised its rules dealing with the nation’s largest animal operations — which hold thousands of hogs, chickens and cattle — since 2008. The agency said in 2021 it planned no changes but announced Friday it had reconsidered in response to an environmental group’s lawsuit.

While not committing to stronger requirements, EPA acknowledged needing more recent data about the extent of the problem — and affordable methods to limit it.
