On arrival at approximately 8;000 FT on a left downwind a level 2 HYD R QTY LO alert was displayed on the EAD. On the HYD synoptic page the fluid level was decreasing. Captain requested the QRH for LEVEL 2 HYD R QTY LO Decreasing or Abnormally High checklist to be completed and took control of the aircraft and radios. We requested and were granted radar vectors to assess the problem and complete the checklist. With guidance from the QRH; we extended the gear with use of the emergency gear release handle. All the gear deployed down and locked; and then we asked for radar vectors for landing using the longer of the two runways. We then requested CFR equipment; briefed the Lead Flight Attendant and prepared for landing. We were cleared for the visual approach and landed safely to a full stop. After coming to a full stop; the Captain set the parking brake and briefed passengers. CFR personnel reported to the crew a large puddle of fluid with an active leak below the aircraft. We had Maintenance come to the aircraft to raise the gear doors and install gear pins for a towed taxi to gate.
B717 First Officer reported right hydraulic system low fluid warning. Crew declared an emergency; ran the procedure; and landed normally.
