S.C. Code § 61-4-530
In considering an application for a permit for the sale of beer or wine at a location within five miles of a political subdivision of another state in which the sale of beer or wine is prohibited, the department must, in addition to the factors required to be considered, consider the proximity of the location to the prohibited area, the likelihood that large crowds may gather from time to time with attendant breaches of the peace, the requirement of increased law enforcement officers, and any other factor which in its judgment should be considered before issuing the permit.
These special considerations, however, do not apply where the application is made with respect to a location within the corporate limits of a municipality.
