SPCC Plans for Electrical Substations....General question
(OP)
I am currently preparing Substation SPCC plans for some clients and am interested on input from others on the subject. I have been preparing SPCC plans for 3 years now, but that is not my specialty. I recently read that secondary oil containment (other than conrete O.C. basins) was defined as structures such as berms and dikes, or on-site absorption materials (PIG barrel, etc.) adequate enough to handle a spill from that site. Is that true ?
What I often run across is that some believe that 6" of gravel in the substation is considered secondary containment, and it may have been true in the past. But I do not think that is the case anymore. I have read thru the CFR code and the EPA scripts and there is not a definitive answer as I could see. I have been keeping up with all the deadline changes and such over the past several years, this is just a question I never really had anyone that I could ask.

"...the volume of containment must be adequate to contain the volume of the largest tank plus have sufficient freeboard for a 100 year storm event. This is usually measured as 110% the volume of the largest tank."

Gravel alone would not slow the oil spill significantly.

2. Assume gravel porosity (P) of 0.35.
3. VO/P=V, where V is the volume of containment.

In some respects, environmental law can be interpreted differently, possibly leading to some creative regional approval and enforcement mechanisms. Spill-containment regs can manifest in varying iterations, though seemingly based on the same set of regulatory concepts.
For instance, some grades of mineral oil are intended for human consumption, but all of it is considered toxic to fish.
