(a) Owners and operators must install an UST system listed in section 11-280.1-l0(c)(l), (3), or (4) storing regulated substances (whether of single or double wall construction) that meets the following requirements: 280.1-8 3 5 8 4 §11-280.1-12 (1) Will prevent releases due to corrosion or structural failure for the operational life of the UST system; (2) Is cathodically protected against corrosion, constructed of non-corrodible material, steel clad with a non-corrodible material, or designed in a manner to prevent the release or threatened release of any stored substance; and (3) Is constructed or lined with material that is compatible with the stored substance. (b) Notwithstanding subsection (a), an UST 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.
