Region 8 Underground Storage Tanks Program
EPA is responsible for implementing a regulatory program for underground storage tanks (USTs). The Region 8 EPA office in Denver, Colorado performs this responsibility in the Region 8 states of Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming. Although EPA has delegated the responsibility for implementing the UST program to the states, facilities located within the exterior boundaries of Indian Reservation in remain under federal jurisdiction.
