I found the escape plans within the Sludge-covered Objects that drop off of the Black Blood of Draenor oozes in the Netherwing Mines.

This quest is also not Repeatable.
I would like to clarify, you can only get this quest if you are of Friendly reputation or above. I'm halfway through Revered and it just dropped for me. So make sure you nab it, even if you're past Friendly. :)

Description
This document outlines a revolt planned by the Murkblood broken. It seems that the dragon was to be used as a diversion to draw attention away from their escape. Looking at all of the corpses littering the mine, it would be safe to assume that their plans failed. Return the escape plans to the Mistress of the Mines.
