Is a release of more than 100 pounds of NH3 in 24 hours reportable?

The release of more than 100 pounds of ammonia (NH3) within a 24-hour period is indeed reportable under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Clean Air Act (CAA) regulations. These regulations mandate that any release of a hazardous substance that meets or exceeds the reportable quantity must be promptly reported to local authorities, allowing them to take appropriate action to protect public health and the environment. Ammonia is classified as a hazardous substance due to its potential to cause serious harm to people and the environment if released in significant amounts. Therefore, understanding the reporting requirements for ammonia releases is critical for compliance and safety in industrial settings.
