S.C. Code Ann. § 58-25-50
The authority may:
(s) Promulgate regulations to carry out the provisions of this chapter.
The authority or other authorized regional transportation organization, in conjunction with all other organizations providing public transportation in the service area, shall prepare and produce a plan to coordinate public transportation services provided by each entity utilizing state funds or funds administered by the State to ensure that resources are being used in the most efficient and cost-effective manner. The coordinated transportation plan must maintain the provision, type, and level of assistance to individuals at least equal in quality to that provided by the human service transportation providers in the service area. The failure of an entity providing these services to comply with the coordinated plan must be reported by the authority or the service provider to the appropriate state agencies or funding authorities which administer, contract, grant, approve, or appropriate funds for services. Transportation resources presently owned by or under contractual agreement of the service provider must remain under the authority of the service provider.
