Answer: No. The federal UST regulation does not require USTs be removed based on age. The regulation sets performance standards for USTs, along with other requirements for owners and operators such as compatibility, operation and maintenance, inspections, and financial responsibility. Under the federal UST regulation, UST owners and operators who continue meeting those requirements may continue to operate their USTs regardless of age.

However, several state implementing UST agencies or local jurisdictions explicitly require or required certain USTs or major components of USTs like tanks or piping be removed from service or replaced, for several reason including once they reach a certain age.

Owners and operators should check with their implementing agency for requirements that apply to them.
