The main purpose of this legislation, known as the Facility for Runway Operations and Safe Transportation Act or the FROST Act, is to enhance airport development by officially including aircraft deicing storage facilities in the definition of what constitutes airport development. This aims to improve safety and efficiency in airport operations, particularly during winter weather conditions when deicing is necessary. One of the key provisions of the FROST Act is the amendment to the existing law that removes the previous limitation on what could be considered as part of airport development.
