Under what condition may the local agency waive the requirement for overfill protection?

The local agency may waive the requirement for overfill protection if the UST is filled by a transfer of less than 25 gallons. This allowance is typically based on the understanding that smaller transfers are less likely to result in overfilling incidents compared to larger ones, thus posing a reduced risk to the environment and safety.

The rationale is that minor amounts of fuel transferred into a tank can be more easily managed, and the need for complex overfill protection systems can be deemed unnecessary. This flexibility can help streamline operations for smaller tanks or during routine maintenance processes, where the risk is considerably lower.

Other options reflect scenarios where the volume of fuel being transferred is either too large or involves automated systems that are designed with their own safety features, thus not qualifying for a waiver under this specific guideline.
