(2) Requires strict compliance with the following guidelines: (a) permits may be granted only to reputable museums, universities, colleges or other historical, scientific or educational institutions, societies or persons with a view toward dissemination of knowledge about cultural properties, provided that the historic preservation officer must be satisfied that the applicant possesses the necessary qualifications to guarantee the property excavation of those sites and objects; and (b) a permit must specify that a summary report of such investigation, containing relevant maps, documents, drawings and photographs, must be submitted to the historic preservation officer, within a specific time period to be determined by the historic preservation officer.
