New to NFPA 20 (2013) Section 11.4.1.2.4 "Single wall fuel tanks shall be enclosed with a wall, curb, or dike sufficient to hold the entire capacity of the tank."
Section 11.4.1.2.8 Tank Venting. If a double-wall tank is installed, the interstitial space between the shells of the diesel fuel storage tank shall be monitored for leakage and annunciated by the engine drive controller. The signal shall be of the supervisory type. If the requirements of NFPA 20 Section 11.4.1.2.8 are met, a curb or dike is not required around the tank per NFPA. FYI NFPA 20 refers to NFPA 37 for larger tanks and provides a lot of guidance for installation and requirements of these tanks. For diesel fuel tanks inside buildings, NFPA 37 (2010) Section 6.3.2.4 states "Fuel tanks within structures shall be provided with spill containment consisting of either a wall, a curb, or a dike having a capacity at least equal to that of the largest tank enclosed." Fuel tanks on roofs are allowed to be any approved secondary containment means per Section 6.3.4.2 Exception 2. Regards, Ryan L.
