Mounded Storage Application

[Casimo5]

I am trying to find information on mounded storage. More specifically, mounded storage being used to reduce spacing requirements.

For example, if a LPG bullet is required to be 100 meters from a fence line, does having that same bullet in a mounded application reduce the spacing requirement? Mounded storage has been used in the past to reduce the flare load contingency, and I have seen this documented, but nothing on spacing requirements.

I am also considering other things, like footprints of a mounded application vs. regular. It would seem that a mound would take up a lot more room in a situation where space is already limited.

Does anyone have experience with this or know where some examples have been documented?

Thanks in advance.

Search for something on military fuel bunkers. I don't know about LPG products but jet fuel is often stored in underground bunkers.

Look in NFPA 59A section 13.6.

You can view the standards for free on-line. Go to:

http://www.nfpa.org/aboutthecodes/list_of_codes_and_standards.asp

Then you will have to click on the standard and then select view standard (which is at the bottom of a long page). It is somewhat tedious but at least they are making the standards available for reading. You cannot print or copy anything.

It has always bothered me that standards that are written into law in many places are only available if you purchase them. This seems a reasonable compromise. However, they don't make it very obvious that you can view the documents for free instead of purchasing them.

Thanks Compositepro! I just needed to see where it was documented somewhere that having a mounded storage relaxed spacing standards in any way.

From NFPA 59A, Section 13.6, it looks like above ground and mounded storage are treated the same way as far as spacing goes. It looks like you need to go underground to relax spacing standards.

Exactly what I needed. Thanks again!

Go underground and you may have tank containment requirements and leakage monitoring issues. Not sure if it applies to UG LPG tanks, but you might want to check that first.
