A commercial fixed wing flight crew received an EGPWS TERRAIN and a Low Altitude Alert warning from MGW Tower while descending to cross UDDOV Intersection at 2;800 MSL on the VOR-A approach. Reporter believes the crossing altitude is in conflict with a charted 2;409 MSL obstruction (a tower) along the course from MGW VOR to UDDOV.

Narrative

We were flying the VOR-A to MGW for landing on Runway 36. Visual with the airport was observed at 1.0 DME from MGW VOR and 2;900 MSL. At MGW 337 degrees/1.0 DME and 2;800 MSL; EGPWS (obstacle; pull up) warning annunciated in cockpit with a subsequent low altitude alert warning from MGW Tower. There is a radio tower at 2;425 [2;409] MSL along the final approach course and it was in sight. A turn correction to the right was performed to avoid the tower. Visual with the ground was maintained from 3;000 MSL and below. VOR-A approach altitudes and final approach course were followed. No further warnings were annunciated or observed and the aircraft landed safely on Runway 36.I suggest the company and/or FAA review[s] the published altitudes for this particular approach and the approach itself. There is only slightly less than a 300 FT clearance between the tower/obstacle along the final approach course and the published step down altitude (2;720 FT) (for which 2;800 FT must be entered into the Altitude Pre-Selector). Previous GPWS warnings have occurred on this approach. Also; this is the only approach that is available for a non-circling landing on Runway 36 for aircraft not equipped with GPS or RNAV.
