Is ammonia included on the EPA toxic chemical list?

Ammonia is indeed included on the EPA toxic chemical list. The EPA maintains this list under the Emergency Planning and Community Right-to-Know Act (EPCRA) as a means to help manage and inform the public about chemicals that can pose health risks. Ammonia is classified as a hazardous substance due to its potential harmful effects on human health and the environment, especially at elevated concentrations.

Its inclusion on this list highlights the importance of proper handling, storage, and reporting for facilities that utilize ammonia in their operations. This safeguards both worker safety and the surrounding community from potential exposure to toxic substances.

The other options do not accurately reflect the status of ammonia concerning EPA regulations. Ammonia is regulated regardless of quantity or geographical location, making those statements incorrect.
