Beginning January 22, 2018, agricultural operations must begin reporting hazardous waste emissions for ammonia and hydrogen sulfide exceeding a reportable quantity for a 24-hour period.  This new requirement for animal operations is the result of a recent court ruling on an exemption finalized by the Environmental Protection Agency (EPA) under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).  This new requirement will impact large livestock operations in Maryland and Delaware.  Livestock operations emitting more than 100lbs of ammonia or hydrogen sulfide per 24-hour period will be required to file a continuous release report with the National Response Center (NRC).  A livestock operation failing to file this continuous release report with NRC will face fines if a release is discovered.
