Factory Espionage

I have been watching this factory, belonging to a giant oil manufacturing company, for several weeks. It is suspected that they dump oil and old equipment in a nearby lake, destroying all wild life in the area.
This photo, unfortunately, doesn't prove anything, but it is important information, since the area is well guarded. I managed to sneak in, when one of the guards were taking a nap.
The building in the middle is the main power facililty, which is the first target in case of a sabotage attack..
