If the registrars of voters do not receive the notice of canvass from an elector, completed and signed, within 30 days after the date the notice was mailed to such elector, they shall take such action with respect to the removal of the elector's name from the registry list as they shall deem appropriate, subject to the requirements of Section 9-32-9. Such action may be based on other information which they may have received concerning the elector.
