Another possibility would be them burning off Hydrazine, which 
is used for the various small positioning thrusters.  Does anyone
know for sure what they do with the leftover Hydrazine in the 
shuttle after landing?  It is nasty stuff; we used to use it in 
sounding rockets, and the Hydrazine test range had a telephone pole 
that was visible from the main gates about half a mile away, with 
green, amber and red lights on top.  If green was lit, you were
OK to drive the half mile in to the test trailers; if amber, stop
and wait, since something dangerous was happening, and if red, 
get to the nearest phone and call GSFC security to say "Oh hell..."
