Narrative:

We were cleared to intercept the localizer about 10 miles out and to slow to 160 KTS. When we selected flaps to 30 the first officer noticed that the flaps had stopped at 28. We selected the flight control page on the mfd and found that the left hand flap was at 28 and the right hand flap was at 30. We advised ATC that we were not going to be able to continue the approach and we would need to be vectored away from traffic to deal with a mechanical issue.we leveled at 4;000 while the first officer performed the QRH but were unable to lower the flaps any more than 20 degrees. We then declared an emergency and asked for the center runway because it was the longest available. The company was notified and we alerted the flight attendants but advised that preparation of the cabin was not necessary because our condition had not deteriorated to that level. We landed without incident and taxied off the runway. We assessed the aircraft and found it fully functional to taxi to the gate and; therefore; canceled the emergency. I want to make it very clear that this emergency landing was completed with five MEL's including the autopilot out of service and on a single pack. The work load was much more difficult and could have been compromised if weather or other systems had failed. I can see the logic behind not accepting a jet for flight into conditions that might deteriorate with MEL's that could seriously compromise the safety of a flight.
