Welcome to the Chatter with BNC weekly podcast. Business North Carolina Magazine staffers talk with some of the Tar Heel State's most interesting people.   On today’s episode, Chris Platé describes his work as president of the N.C. Economic Development Association, a Raleigh-based trade group with more than 800 members. Plate has led the Monroe-Union County Economic Development Commission since 2000, a period in which the area adjacent to Charlotte has experienced explosive growth. North Carolina needs more industrial sites ready to house new corporate entrants because so many existing sites have been filled in recent years, Plate notes.
