LAC 33:XI.305. Installation Requirements for Partially–Deferred UST Systems

A. The requirements in this Section apply to UST systems partially excluded under LAC 33:XI.101.C.1.a, b, and c. B. Owners and operators shall install a UST system listed in LAC 33:XI.101.C.1.a, b, or c for the purpose of storing regulated substances (whether of single or double-wall construction) that meets the following requirements. 1. The UST system will prevent releases due to corrosion or structural failure for the operational life of the UST system. 2. The UST system is cathodically protected against corrosion, is constructed of noncorrodible material or of metal clad with a noncorrodible material, or is designed in a manner to prevent the release or threatened release of any stored substance. 3. The UST system is constructed or lined with material that is compatible with the stored substance. C. Notwithstanding Subsection B of this Section, a UST system without corrosion protection may be installed at a site that a corrosion expert determines is not corrosive enough to cause the UST system to have a release due to corrosion during its operating life. Owners and operators shall maintain records that demonstrate compliance with the requirements of this Subsection for the remaining life of the tank. D. LAC 33:XI.599.Appendix A lists codes of practice developed by nationally-recognized associations or independent testing laboratories that shall be used to comply with these regulations.
