Any written objections to the proposed assessment, and/or requests for an alternate hearing date, submitted to the hearing examiner must identify therein the parcel of property proposed to be assessed. The notice, or copy thereof, may, but need not, be used for that purpose and in the event the hearing examiner agrees to an alternate time or date for the owner’s appearance, the Department will notify the owner as to that alternate time and/or date. Written objections to the proposed assessment may be submitted to the hearing examiner, but must be submitted prior to the commencement of the scheduled hearing.
