Outdoor, above ground, double wall tank for ethanol storage constructed per UL-142. Primary tank has conservation vent/flame arrester and emergency relief vent.
Re: the double wall secondary containment, if this is not sealed (like a dike) and opened to the atmosphere, is a flame arrester and/or emergency vent required? If this is sealed, is a flame arrester and/or emergency vent required?
