Environmental groups are lobbying for regulation of dairy and hog concentrated animal feeding operations.
The Center for Food Safety and others have filed a petition to the Environmental Protection Agency wanting them to govern CAFO methane emissions under the Clean Air Act.
Senior Attorney Amy Van Saun tells Brownfield the petition asks operations that confine at least 500 cows or 1,000 hogs to cut emissions by the same amount achieved through pasture-based farming.
