  • Revised National Pollutant Discharge Elimination System Permit Regulation and Effluent Limitations Guidelines for Concentrated Animal Feeding Operations (2011) (PDF) (404K)
  • Under the Federal Water Pollution Control Act (Clean Water Act or CWA), EPA is revising the National Pollutant Discharge Elimination System (NPDES) permitting requirements and Effluent Limitations Guidelines and Standards (ELGs) for concentrated animal feeding operations (CAFOs) in response to the order issued by the U.S. Court of Appeals for the Fifth Circuit in National Pork Producers et al. v. EPA. The court vacates those provisions of the 2008 Rule that create liability for failing to apply for an NPDES permit and upholds the provisions of the 2008 Rule that allow permitting authorities to regulate a permitted CAFO’s land application and include these requirements in a CAFO’s NPDES permit.

EPA, 399 F.3d 486 (2d Cir. 2005).
