Home Pueblo Chemical Agent-Destruction Pilot Plant (PCAPP) Environmental Activities at PCAPP

The Pueblo Chemical Agent-Destruction Pilot Plant team is committed to destroying the chemical weapons stockpile at the U.S. Army Pueblo Chemical Depot while protecting the workforce, public and environment.

The PCAPP team fulfills this commitment by adhering to numerous local, state and federal laws and regulations. This includes the Resource Conservation and Recovery Act, which gives the U.S. Environmental Protection Agency authority to control hazardous waste, including generation, transportation, treatment, storage and disposal, to protect human health and the environment.

In addition, PCAPP operates under a hazardous waste permit from the Colorado Department of Public Health and Environment. This permit was granted after numerous Army studies determined the destruction of the stockpile would have no significant impacts to human health or the environment. Throughout the lifecycle of the plant, any major permit modifications require a public comment period and approval by the state.

Learn more about our permits and environmental activities by accessing the links and information on this page, or by contacting the Pueblo Chemical Stockpile Outreach Office at pueblooutreach@iem.com or (719) 546-0400.
