The design?
Typical drawings?
It's a mound of earth. Usually covered in plastic to increase its effectiveness and stop it washing away in the rain.
What more do you need to know?

I remember ARAMCO practice ; top width = 1200 mm, max . height =2000 mm, max. slope = 1.0 V; 1.5 H ; the dike surface is covered with asphalt concrete 50 mm .
If together with access road, the top width 6000 mm.
Does my comment answer to your post ? If not, provide some data , the reason for earthen dike etc..
RE: earthen dykes for 500,000 gallons above ground fuel oil storage tankl
2m high is actually fairly low - I've seen 5m in my time.

But the picture you have posted seems 2.0 m high dike. The dike ht should be decided acc.to availability of area, fill material etc.. The info. that i provided from ARAMCO standard dwg.

That's a full grown man (~1.8m), not a small child trying to run up the slope.
That digger is probably over 2m high for scale as well.
I would easily put that bund at 5m high from the floor of the bund.

I think you'll be looking for a long time.... As said before, earthen dykes are basically just compacted lumps of stone, sand, mud and whatever else the builder had lying around which he then hopefully covered with something relatively impermeable, or grass, to stop it getting washed away. They really are the forgotten child of tank farm design.
Pipe entry though the bunds were allowed, but following a number of failures, nowadays are frowned on unless incorporated into a concrete wall or something a bit more substantial.
What's an SPCC?
If the work involved any removal and replacement of material I would be very concerned about the re-instatement and the join between existing and new creating a failure plane.
It is not uncommon for tank repairs to remove a section of the bund for easy ground level access, but replacement is sometimes an issue.

SPCC is the EPA-required Spill Prevention, Control, and Countermeasures Plan, part of the Clean Water Act, and intended to prevent oils from reaching public waters. More information can be found below.

Chicopee - make sure your local state authority is okay with just earthen dikes (i.e. permeability through the soil is acceptably low). Especially with lower molecular weight materials, liners are often needed to control permeability.
Also, if you are in the USA, you may want to revise spelling to dike, instead of dyke. The former word is the common spelling for a containment while the latter word is typically a pejorative term.
