The Pueblo Chemical Agent-Destruction Pilot Plant team destroyed the chemical weapons stockpile formerly stored at the U.S. Army Pueblo Chemical Depot, now known as the U.S. Army Chemical Materials Activity-West, and is managing the closure phase 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 operated 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 required a public comment period and approval by the state.
