The Hickory Daily Record reports that environmental permits have been issued for construction at the data centre campus in the town of Maiden.
Also, a contractor for work at the site has filed for a building permit.
It's not clear if the construction is for a second data centre that was planned, or for something else.
Apple, based in Cupertino, Calif., uses the data centre to store information as part of its iCloud network.
Maiden town manager Todd Herms told the newspaper he couldn't say exactly what the company was building.Suggest a correction
