Narrative:

At 8000 ft; 10 south of rbv VOR asked for lower to get out of icing due to a left bleed failure. A dash 8 ahead confirmed light icing at 8000. Temperature was two degrees celsius. Because we needed to get out of icing and ATC would not let us descend out of it; we declared an emergency and descended to 6000 with an amended clearance.
