On December 18, 2008, the EPA published a Final Rule, "CERCLA/EPCRA Administrative Reporting Exemption for Air Releases of Hazardous Substances from Animal Waste at Farms (73 FR 76948) ("the Final Rule"). The Final Rule established exemptions from certain reporting requirements under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and the Emergency Planning and Community Right to Know Act (EPCRA). On January 15, 2009, Waterkeeper Alliance, Sierra Club, the Humane Society of the United States, Environmental Integrity Project, the Center for Food Safety, and Citizens for Pennsylvania's Future (collectively, "Waterkeeper") filed a Petition for Review of the Final Rule. The petition challenged the exemptions under both CERCLA and EPCRA. On March 17, 2009, the National Pork Producers Council filed its Petition for Review challenging a portion of the Final Rule that amended the EPCRA regulations. The two cases were consolidated. On February 11, 2009, the National Chicken Council, National Turkey Federation, and U.S. Poultry & Egg Association moved to intervene on behalf of the EPA to assert their interests in the Final Rule. The case was held in abeyance so that the Parties could participate in the D.C. Circuit Mediation Program. On April 11, 2017, the DC Circuit Court vacated the rule. The court extended its mandate until November 14, 2017. The EPA is issuing a final rule in accordance with the court's mandate.
