All licenses expire on December 31st of each biennial period and may be renewed thereafter for 2-year periods without further examination, upon the payment of the proper renewal fee as set forth in the rules. A person who fails to renew that person's license within 2 years following the expiration of the license must take an examination as a condition of licensure.
The Board of Licensure of Water System Operators shall notify a person registered under this subchapter of the date of expiration of that person's license and the fee required for its renewal for a 2-year period. The notice must be mailed to the person's last-known address at least 30 days in advance of the expiration date of that person's license.
