Section 33-24-08-02 - Installation requirements for partially excluded underground storage tank systems

1. Owners and operators installing an underground storage tank system listed in subsection 3 of section 33-24-08-01 for the purpose of storing regulated substances (whether of single-wall or double-wall construction) shall meet the following requirements:

a. Will prevent releases due to corrosion or structural failure for the operational life of the underground storage tank system;

b. Is cathodically protected against corrosion, constructed of noncorrodible material, steel clad with a noncorrodible material, or designed in a manner to prevent the release or threatened release of any stored substance; and

c. Is constructed or lined with material that is compatible with the stored substance.

2. Notwithstanding subsection 1, an underground storage tank system without corrosion protection may be installed at a site that is determined by a corrosion expert not to be corrosive enough to cause it to have a release due to corrosion during its operating life. Owners and operators must maintain records that demonstrate compliance with the requirements of this subsection for the remaining life of the tank.
