Narrative:

While en route from white plains, ny, to columbus, oh, at FL280, we experienced an uncommanded torque rollback of the left engine. My flying partner, PIC and the PF, executed the memory items to feather and secure the engine. We declared an emergency to ZDC and asked for a 'closest airport' with 5000 ft runway and crash fire rescue equipment equipment. They recommended a turn towards pittsburgh international and we flew in to runway 10R at pit. We made a safe and uneventful landing. Afterwards, a mechanic looked at the left engine. He found a large amount of water in the fuel tanks (left nacelle tank and left main tanks) and he surmised that the water had frozen while we were at FL280 for approximately 1 hour 15 mins. Our company policy is to add prist to the fuel tanks once per day minimum, which we added prior to the flight, as well as sumping the tanks to check for water. We found no water prior to the flight. As of late, our company has not given our flight crew any information regarding a change of the fueling policy.
