This plat must be prepared and certified by a professional land surveyor. The plat filed with the County Recorder must contain a note, prominently displayed, that states the owner's or operator's obligation to restrict disturbance of the site as specified in Section 725.217(c). In addition, the owner or operator must submit to the Agency and to the County Recorder a record of the type, location, and quantity of hazardous waste disposed of within each cell or area of the facility.
