Managing Hazardous Waste

We strengthen regulations and streamline waste management

Imperial County CUPA

The Imperial CUPAs mission is to protect human health and the environment in Imperial County from the harmful effects of hazardous materials and hazardous waste by employing coordinated efforts of Unified Program inspections and enforcement of environmental laws.


To provide a cleaner and healthier environment in Imperial County by; ensuring fair and consistent application of Unified Program requirements, educating the regulated community and public, and upholding the principals of Environmental Justice.

On January 1, 2005, the Department of Toxic Substances Control (DTSC) was authorized by the California Environmental Protection Agency (Cal/EPA) as the Imperial County Certified Unified Program Agency (CUPA).

The main objective of a Unified Program is to combine and coordinate six formerly separate elements into a single agency.  This makes it simpler for businesses to comply with regulations that protect public health, safety, and the environment.  For more information on the following Unified Program, click on the following:
