The EPA is studying stricter regulations on large livestock facilities that release pollutants into waterways.
The Agency has not revised those rules in the last 15 years. Leaders previously said they were not planning on any changes. The announcement came late last week after a lawsuit by an environmental group, Food and Water Watch.
EPA records show roughly 6,000 of the nation’s 21,000 concentrated animal feeding operations have permits. EPA says it will gather more information and conduct a detailed study to make an informed decision.
