Would a sump pit that is not higher than the finished floor be considered within working space as described in 110.26? I stubbed up a feeder in a basement and upon returning after the concrete pour, I find the plumber placed his sump pit so in encroaches several inches into the area where my panel will be placed.
 
Also, you would have to consider the floor at the bottom of the pit. What would that do to your workspace and height. :)
 
It there will be a grating over the pit, and if a person could stand in front of your panel (even if necessary standing on that grating) and still have the working clearance (meaning that any pipes or wires associated with the pit are not within the required clearance), then I would say this is acceptable. But it absolutely depends on their being a safe way to stand over the pit, and on there being no pipes or wires in the way.
 
It's a sump pit made of a polymer material. There are two pipes emerging from the pit vertically but the pipes themselves are not within the working space, just the actual pit itself encroaches about 12" into what I consider to be my space. I can stand on the lid of the pit if need be.
 
I agree with Charlie that a cover or grate over the pit changes things with no encroachment from piping etc.

In that case, as long as you have your 30" in the other direction from the pipes, you're golden.

Added: If it's mentioned, liken it to a panel behind a door. It is (or can readily be rendered) accessible.
