2005 Second Circuit Court Decision on CAFOs

The revised CAFO regulations expanded the number of operations covered by the rule to an estimated 15,500 and included requirements to address the land application of manure from CAFOs. The rule became effective on April 14, 2003 and authorized NPDES states were required to modify their programs by February 2005 and develop state technical standards.

On February 28, 2005, the Second Circuit issued its decision in Waterkeeper Alliance et al. v. EPA, 399 F.3d 486. EPA is currently updating the CAFO rule to reflect the changes requested by the Court. Additional information on the 2005 Second Circuit Decision.
