Upon the written request of an applicant or his agent and the payment of a fee of $0.25 per name or $10, whichever is more, either the Borough Clerk or the Tax Assessor shall make and certify a list from the current tax duplicates of names and addresses of owners within the Borough to whom the applicant is required to give notice. The applicant shall be entitled to rely upon the information contained in such list, and failure to give notice to any owner not on the list shall not invalidate the hearing or proceeding. (Note: For the names and addresses of property owners in adjacent municipalities, when required, contact the respective Clerks.)
