The requirement for the owner/operator to submit a full written report after detecting an unauthorized release is set at 5 days to ensure timely investigation and remediation. This timeframe allows the responsible party to gather all necessary information regarding the incident; this includes understanding the extent of the release, the impact on the environment, and the steps taken or proposed to mitigate any damage.

Additionally, the 5-day timeframe is crucial for regulatory compliance and helps to facilitate immediate corrective actions, thereby minimizing potential harm from the release. By allowing this duration, it balances the need for prompt reporting with the practicalities of gathering comprehensive data that reflects the situation accurately. Recognizing that immediate reporting—like within 8 hours or 24 hours—might not provide enough time for an accurate assessment, the 5-day requirement exemplifies a structured approach to handling environmental concerns effectively.

This timeframe also aligns with the regulations set forth within the context of California's requirements for underground storage tanks (USTs), underscoring the importance of thorough reporting as part of responsible environmental management practices.
