The correct answer is: Any of the above

To notify the EPA at least 30 days prior to permanently closing a UST (Underground Storage Tank) system, owners and operators have the option to use various methods of communication, which includes calling, emailing, or mailing the notification. This flexibility in communication ensures that the notification process is accessible and can accommodate different preferences or circumstances of the owners and operators. It emphasizes the importance of timely communication with the EPA regarding significant actions related to UST systems, ensuring compliance with regulations and proper management of the UST facilities. By allowing any of these methods, the EPA facilitates a streamlined process, which helps owners and operators meet legal obligations effectively.
