Procedure; Chart Or Publication
Performed normal preflight duties and procedures; ATIS advertised Runway 10L [departures] IMC conditions. 300 overcast plus 1/2 mile and fog. During our briefing we noted company provided single engine failure procedure requires PDX VOR to identify 8.4 DME fix. We checked radio aid and found it to be inoperative. Checked chart NOTAMs as well as flight release NOTAMs. PDX VOR should have been in service. We contacted ATC (PDX Ground) and they stated that the PDX VOR was decommissioned over 1 month ago. Our engine failure procedure requires us to identify the PDX 8.4 DME fix so that we avoid rising terrain in the Columbia Gorge. Since we cannot determine how fast we will climb on a single engine waiting until we reach 1;031 FT could cause us to enter this area of rising terrain. If we reach 1;031 FT before 8.4 DME we are allowed to turn and head out the Columbia River towards the Pacific Ocean.[There appears to have been] inadequate review by the company when providing engine out procedures at our scheduled airports. An alternate procedure should have been provided without our inquiring.
An A320 flight crew discovered their company's special engine failure procedure for departures from Runway 10L at PDX required DME information from the OTS PDX VOR.
