EPA sued for allowing slaughterhouses to pollute waterways

EPA last revised pollution standards for thousands of meat-processing plants 15 years ago and some guidance dates back to 70s

A coalition of conservation and community groups representing millions of people is suing the Environmental Protection Agency (EPA) for refusing to update national water pollution standards for slaughterhouses.

The EPA decision allows thousands of meat and poultry processing plants to continue using outdated pollution-control technology, which has been linked to the contamination of waterways across the US.
