Who is Regulated by the Effluent Guidelines?
The existing effluent guidelines regulations for feedlots apply to operations with 1,000 AU and greater. EPA is proposing to establish effluent guidelines requirements for the beef, dairy, swine, chicken and turkey subcategories that would apply to any operations in these subcategories that are defined as a CAFO under either the twotier or threetier structure. Also as discussed in detail in Section VII.B.3, EPA is also requesting comment on an option under which the effluent guidelines proposed today would not be applicable to facilities under 1,000 AU. Under this approach, AFOs below this threshold would be permitted based on an alternate set of effluent guidelines, or the best professional judgment of the permit writer. After evaluating public comments EPA may decide to consider this option. At that time EPA would develop and make available for comment an analysis of why it is appropriate to promulgate different effluent guidelines requirements or no effluent guidelines for CAFOs tha
