technical correction; underground storage; closure

This bill updates Arizona Revised Statutes to clarify the requirements for safely closing or changing the service of underground storage tanks. It mandates that the state director establish specific rules for these closures, ensuring they prevent the release of harmful substances and align with current federal regulations. Until those new state rules are finalized, tank operators must follow existing federal guidelines for temporary closures, permanent shutdowns, or service changes. The legislation directly affects entities responsible for managing underground storage tanks by providing a clear legal framework for their decommissioning.
