Ten community, environmental, and animal protection advocacy groups sued the Environmental Protection Agency (EPA), alleging that the agency has failed to regulate water pollution from factory farming in a way that violates the Clean Water Act. Plaintiffs seek declaratory judgment and injunctive relief, including an order compelling the EPA to promulgate regulations governing wastewater discharges from meat and poultry product facilities. The plaintiffs are represented by Earthjustice and the Environmental Integrity Project.
