A federal court has ruled that the air quality rules for raising livestock are too lenient:

……… Most livestock farming in industrialized countries takes place on large enclosed farms, known in the United States as Concentrated Animal Feeding Operations (CAFOs), that house hundreds or thousands of animals. Many environmental and public health groups say CAFOs are major air and water polluters and should be regulated more stringently. Farmers and trade organizations typically respond that CAFOS already are adequately regulated and do not threaten nearby communities or the environment.

On April 11, 2017, the U.S. Court of Appeals for the D.C. Circuit struck down a rule, issued by the Environmental Protection Agency in 2008, that exempted livestock farms from reporting hazardous air emissions from animal waste. Unless EPA appeals to the Supreme Court, these farms will have to report releases of substances such as ammonia and hydrogen sulfide starting later this year.

Agriculture, particularly Big Ag, has been skating for way too long on environmental regulations.
