    <text>Phase II Report—Site Geology. The applicant shall prepare and submit to the Approving Authority ten copies of a Phase II report describing the soils, geology, and hydrology of the proposed site. This report shall be developed and signed by a geologist who possesses at least a bachelor's degree from an accredited college or university in the field of geology or a related field of earth science. The Phase II report shall include the following information in sufficient detail to permit a comprehensive review of the project:</text>
