This plat shall be prepared and certified by a professional land surveyor and shall be in a form acceptable to the Registry of Deeds. The plat shall contain a note prominently displayed which states the obligation to restrict disturbance of the site of the land disposal unit or facility in accordance with 310 CMR 30.590.
