GF:
What is curious about the MVA overlay is, why can't a MOCA be established on the inbound radios to POM? Set a waypoint or DME fix and lower the minimum altitude nearing the VOR. I am not sure though about the secondary zone for airway obstacle clearance, might be a problem on the north side of V264.
Difficult to say without an obstacle assessment. The primary area of the airway has to have not less than 2,000 feet of ROC because this area is within a Designated Mountainous Area. OTOH, the MVA over flat areas like this needs only 1,000 feet of ROC.
The fact the MCA for V-264 from the west side of POM is 5,600 for V-264 on the east side of POM tells me there is an obstacle issue. Then again, the MCA for V-197 NW of POM is 11,800, which makes no sense at all.
Added: I see now the 11,800 is for minimum turn area. That would be interesting if your clearance was to climb to and maintain 11,000.
