Storage Tank Program

Our Storage Tank Program (STP) team regulates the installation and operation of STP-regulated storage tank systems and oversees cleanup at sites impacted by eligible leaking tanks to protect Wyoming’s land and groundwater from contamination.

The two primary functions of our program are to:

  1. Ensure tank system owners and operators are in compliance.
  2. Oversee corrective actions and remediation at eligible sites.

To learn more about how the SHWD STP reduces the threat of water pollution caused by storage tanks and implements environmental remediation, leak prevention, and leak detection practices, browse the compliance, remediation and resources pages on the right-hand side of this page.
