Secondary Containment CFC 50 or 57?

[nealderidder]

I'm working on a craft distillery and trying to determine whether or not I need secondary containment for large product tanks (1,000 gal). This is in CA.

CFC 5004.2.2 says to provide secondary containment per table 5004.2.2. This table says "See Chapter 57".

CFC 5703.4 notes that spill control and secondary containment are required when MAQ is exceeded (MAQ is being exceeded in this case) and where required by 5004.2 and then says to provide this control and containment per 5004.2

5004.2.2 calls for secondary containment where required by table 5004.2.2 which refers me back to chapter 57.

I'm stuck in a loop.

This is an H3 area with class IB liquids (ethanol) in quantities greater than that allowed in control areas.

So do I need secondary containment?

I got a cold for Christmas so maybe my brain just isn't working right...

What is in the tank??

Sorry missed the ethanol

What is the flashpoint??

Straight stuff or mixed?

Meet any of the chapter 57 exceptions ?

OP says that ethanol is exceeding the MAQ's.

Straight up - well, 195 proof anyway. This is prior to mixing and qualifies as a Class IB liquid (flash point 70 degrees)

Nope, this isn't barrel storage it's stainless steel product tanks.

nealderidder,

IMO, Yes, you need secondary containment........See
Section 5004.2.2.3 - Indoor Design.

But before you get to 5004.2.2.3 you get to 5004.2.2 which says secondary containment is to be provided where required by table 5004.2.2

Table 5004.2.2 also refers to Ch. 57.
See Section 5703.4.

Maybe I should have stayed in bed today.

There is an important comma in 5703.4 I might have skipped over.

5703.4 - "Where the MAQ per control area is exceeded, and where required by section 5004.2...."

If you stop reading at the comma chapter 57 says I need spill control and containment. Then I go back to chapter 50 for the particulars.

Thanks for the quick feedback!
