York County along the North Carolina border contains Rock Hill and Fort Mill and is within the 10-mile Emergency Planning Zone of Catawba Nuclear Station. Lake Wylie — the cooling reservoir for the nuclear plant — borders the county. The county is part of the Charlotte North Carolina metropolitan area and has been one of the fastest growing in the Carolinas. The Catawba River creates flooding risk and the nuclear proximity requires specialized emergency planning for the county's rapidly growing population.
