Narrative:
We were at 3;000 ft being vectored for the ILS approach. We were speed restricted to 170 KTS for traffic in front of us; in IMC; and encountering mixed icing conditions. At this point we received two cas messages: bleed 1 fail and bleed 2 fail. We reverted to the QRH for the appropriate checklist and commenced the required procedures. This message was followed by an: a-i wingstab inhb. Moments later ATC issued our approach clearance and requested that we reduce to 150 KTS followed by a correction to slow to 'final approach speed.' we replied we were unable and as a result ATC queried if we were declaring an emergency. I did reply that we were declaring an emergency at this point and we needed maximum forward speed to exit and avoid icing conditions as we were in icing conditions; and accumulating ice; with no anti-icing capabilities. We were then cleared for the ILS approach and handed off to tower; which cleared us to land and asked if we needed assistance; we respectfully declined the offer. Per the QRH we had to turn the affected bleeds off for one minute and then open them in an attempt to reset them. We broke out of the overcast layer at 1;100 ft with 5 seconds remaining on our time; and a successful reset was accomplished at the one-minute mark. With the anti-ice capability restored we successfully accomplished a normal landing. No passengers were injured or inconvenienced during the approach and landing.

Title: EMB300 flight crew experiences airfoil anti-ice failure during approach in icing conditions. The QRH is consulted and the system is reset successfully just prior to landing.
Narrative: We were at 3;000 FT being vectored for the ILS Approach. We were speed restricted to 170 KTS for traffic in front of us; in IMC; and encountering mixed icing conditions. At this point we received two CAS messages: BLEED 1 FAIL and BLEED 2 FAIL. We reverted to the QRH for the appropriate checklist and commenced the required procedures. This message was followed by an: A-I WINGSTAB INHB. Moments later ATC issued our approach clearance and requested that we reduce to 150 KTS followed by a correction to slow to 'Final approach speed.' We replied we were unable and as a result ATC queried if we were declaring an emergency. I did reply that we were declaring an emergency at this point and we needed maximum forward speed to exit and avoid icing conditions as we were in icing conditions; and accumulating ice; with no anti-icing capabilities.
