Due to legislative changes in the Consolidated Appropriations Act, 2018 (Omnibus Bill), “air emissions from animal waste at a farm” are exempt from reporting under CERCLA. On May 2, 2018, the D.C. Circuit Court of Appeals issued its mandate vacating the 2008 final rule. However, farms will remain exempt from the CERCLA reporting requirements as a result of the FARM Act. For more information, please see: CERCLA and EPCRA Reporting Requirements for Air Releases of Hazardous Substances from Animal Waste at Farms.
