The latest revision date on the paper copy I have is May 1999. I don't think it would have applied in your case. The guideline for indoor storage tanks of one or more tanks is a maximum of 10,000 gallons if the liquid is a class 1 liquid. You are way over that. And of course they require sprinklers and drainage to a safe location for the tank spill and sprinkler discharge water. I am guessing it was their version of NFPA 30.

Think one hell of a party. Got a code reference to a sprinkler density/protection scheme? FM 7-29 references a 7-88 but I can't find any 7-88. NFPA 30 (24.6) doesn't seem to say anything much about this even suggesting it's OK with none (after a hazard analysis, of course). If the goal is to keep a fire not involving the liquid from breaking a tank probably don't need much density. If the goal is to save anything after a tank rupture and fire then foam is probably the only answer. I'd think the code or standard would say something? Most of the building is drums in racks so I think were at .6/3000 plus in-racks. Thinking just extending into this small area has very little cost. Yes, yes I know PE should be involved to specify the approach for the holistic fire protection matters including spill containment, venting, tank specifications, electrical concerns etc. Lets for now assume this is the real ugly world and this party doesn't exist yet.
