The bill S. 522 proposes amendments to Act 1235 of 1970, specifically changing the names of the Charleston County Airport District and the Charleston County Aviation Authority to the Charleston Regional Airport District and the Charleston Regional Aviation Authority, respectively. The amendments are reflected in the updated legal language, where the corporate name of the Airport District is changed to "Charleston County Regional Airport District" and the authority is renamed "Charleston County Regional Aviation Authority."

Additionally, the bill outlines the composition and appointment process for the members of the Charleston Regional Aviation Authority, which will consist of seven members, including appointments by the Governor and ex officio members from the City and County Councils. The terms for the appointed members will last four years, and the bill stipulates that they will receive per diem, mileage, and subsistence as provided by law. The act will take effect upon approval by the Governor.
