Managing Manure at Concentrated Animal
Feeding Operations
Summary
EPA is publishing technical guidance to help NPDESpermit authorities (States and EPA
Regions), permittees, and technical service providers implement EPA 's February 2003 revised
Permit Regulations and Effluent Guidelines for Concentrated Animal Feeding Operations
(CAFOs). This document will help permit authorities write permits for CAFOs that incorporate
the revised effluent guidelines. It will also help operators of CAFOs meet these new limitations.
Background on CAFO Regulations
EPA published revised regulations for CAFOs
under the Clean Water Act on February 12,
2003. The rules established performance
expectations for existing and new sources to
ensure they store manure and wastewater
properly and expectations for proper land
application practices at the CAFO.
The rules apply to about 17,000 livestock
operations across the country. Under the rules
all large CAFOs are required to apply for a
permit, submit an annual report, and develop
and follow a plan for handling manure and
wastewater. In addition, the rules move
efforts forward to protect the environment by:
controlling land application of manure and
wastewater, covering all major animal
agriculture sectors, requiring all CAFOs to
apply for an NPDES permit, and increasing
public access to information through CAFO
annual reports.
Summary of the Technical Guidance
The guidance focuses on site-specific
requirements of the CAFO rules such as
adequate storage of process wastewater and
alternatives to setbacks for the land
application of manure. The guidance presents
many examples including land application rate
calculations, sampling methods, National
Nutrient Management Technical Standards for
land application, and case studies for the
voluntary alternative performance standards
program. Additional technical resources and
references addressed in the guidance include
Manure Management Planner, appropriateness
of winter spreading of manure, Phosphorus
Index and Erosion Loss control tools, and
USDA Comprehensive Nutrient Management
Plans.
