Update!
On January 19, 2018, Friday, EPA filed a motion with the D.C. Circuit Court of Appeals to further delay issuance of the mandate. Please check EPA's website to reach recent information on the court mandate.

The U.S. EPA has recently published a fact sheet that provides an overview of the CERCLA reporting requirements for air releases from animal farms. According to the fact sheet, farms with animal operations that release more than 100 pounds of ammonia or hydrogen sulfide in a 24-hour period may be required to report these air emissions as early as January 22, 2018.
The Court is expected to issue its order on January 22, 2018 and farms do not have to report until the Court issues its mandate, but we urge farms to review the sources below and familiarize themselves with the CERCLA continuous release reporting process. We will update this webpage as more information becomes available.
