What happens to the registration of a CBS facility when it has been permanently closed?

When a CBS (Commercial Business Site) facility is permanently closed, its registration is terminated and is no longer valid. This is because the regulatory framework governing UST (Underground Storage Tank) systems prioritizes the safe operation and oversight of such facilities. Once a facility is classified as permanently closed, it signifies that the USTs are no longer in use and that the associated risks and regulatory responsibilities cease.

The termination of registration helps ensure that there are no liabilities or maintenance obligations remaining for a non-operational site, and allows regulatory agencies to focus their resources and oversight on active and operational facilities. Thus, the registration does not stay valid for future use, nor is it subject to renewal, since the site is permanently out of operation.
