Persons who wish to disclose the availability of a water right or the right to use water or portion thereof for transfer, but do not wish to deposit the right in the bank, may request to be listed by the administrator in a registry at the bank. The request shall be in the format of a request for deposit and shall include all information the administrator deems necessary to prepare the registry of sellers. Any person who has listed a water right or the right to use water for sale in the registry shall notify the administrator within 30 calendar days of the date a contract to transfer a water right or the right to use water or portion thereof is signed.
