The EPA promulgated revised regulations for Concentrated Animal Feeding Operations (CAFOs) on February 12, 2003 (68 FR 7175). Pursuant to section 610 of the Regulatory Flexibility Act, on October 31, 2012, the EPA initiated a review of the 2003 CAFO rule to determine if the provisions as they relate to small entities should be continued without change, or should be rescinded or amended to minimize adverse economic impacts on small entities (77 FR 65840). The EPA solicited and considered comments on the following factors: (1) the continued need for the rule; (2) the nature of complaints or comments received from the public concerning the rule; (3) the complexity of the rule; (4) the extent to which the rule overlaps, duplicates, or conflicts with other Federal, State, or local government rules; and (5) the degree to which technology, economic conditions, or other factors have changed in the area affected by the rule. The public comment period was scheduled originally to end on December 31, 2012, but was extended to March 1, 2013, in response to requests received for additional time to submit comments (78 FR 277). The EPA completed its review on June 3, 2014 and concluded that there is a continued need for the CAFO regulations, and that the comments received did not demonstrate that revisions are necessary at this time to minimize impacts on small entities. The results of the Section 610 review of the 2003 CAFO Rule were summarized in a report and placed in the rulemaking docket.
