Pocahontas County Commission President Martin Saffer says the state boundary shown on Highland New Wind Development's maps don't match U.S. Geological Survey maps.
Based on the geological maps, Saffer says Highland is planning to build one, perhaps two of its 19 wind turbines in West Virginia.
If that's true, he says Highland needs approval from West Virginia regulatory agencies.
Highland says it used GPS technology to chart the Allegheny Mountain crest that divides the two states.
Work began earlier this month on the $60 million wind farm capable of producing 38 megawatts of electricity.
