Narrative:
Approaching valdez in VFR conditions. We had been communicating on 122.2 which was the CTAF on the approach plate and had been used for the 3 yrs I had been here. Then we see an airplane at our altitude just off our left. The aircraft didn't show up on our TCASII and hadn't been heard on 122.2. When we got on the ground, the captain talked to the airport manager who said they had changed the frequency to 122.9 a few days earlier. Both the captain and I hadn't been there within the last week. We then went back and in our WX packet, found in the second sheet of NOTAMS that 122.9 had been commissioned in use.
