Thad, this is a really good question. Non -polar oil and grease would be a very good parameter to monitor for, just
because those rail cars are parked over the vault regularly. It is also good that they have a containment possibility in the
event of equipment failure. Would they close off the vault to prevent flow to the settling pond in that case? I would
also recommend COD (chemical oxygen demand), which will pick up ethanol residue (as well as other chemicals that
can be oxidized). In addition to the monitoring, it would be good for them to document what they do in the event of a
spill — they probably already have this or have shared it with you.

I inspected this Eco Energy facility last week and had a question or two. This site is one of the many fuel storage facilities
located on Buffalo Road in Selma with this particular one having fuel shipped in by train car. The train cars are staged
over a very large underground concrete containment vault that is filled with rail road ballast (Stone) with train tracks
over the top and running through the middle. The vault is drained through a large gate valve that releases the
containment contents into a settling pond. The train cars are full of fuel (Ethanol) that is manually connected to piping
by quick connect fittings and pumped to huge fuel storage tanks for later distribution. I wanted to have them provide
analytical samples from the outlet of the containment vault to ensure there are no existing contamination issues before
I consider issuing an NE approval. Everything looks clean and well maintained, but the unloading area is exposed to the
weather and although they have documented, or remember having any spills in the past, there's a chance they've had
spills in the past. What type of samples would you recommend they take other than Oil & Grease? If you have any other
concerns with this NE please let me know so I can consider those for this NE. Thanks
