North Carolina General Statutes Chapter 130A. Public Health § 130A-252. Definition of mass gathering; applicability of Part

(a) For the purposes of this Part, “mass gathering” means a congregation or assembly of more than 5,000 people in an open space or open air for a period of more than 24 hours. A mass gathering shall include all congregations and assemblies organized or held for any purpose, but shall not include assemblies in permanent buildings or permanent structures designed or intended for use by a large number of people. To determine whether a congregation or assembly extends for more than 24 hours, the period shall begin when the people expected to attend are first permitted on the land where the congregation or assembly will be held and shall end when the people in attendance are expected to depart. To determine whether a congregation or assembly shall consist of more than 5,000 people, the number reasonably expected to attend, as determined from the promotion, advertisement and preparation for the congregation or assembly and from the attendance at prior congregations or assemblies of the same type, shall be considered.

(b) The provisions of this Part do not apply to a permanent stadium with an adjacent campground that hosts an annual event that has, within the previous five years, attracted crowds in excess of 70,000 people. The term “stadium” includes speedways and dragways.
