What information must be included in the operational records for USTs?

Operational records for Underground Storage Tanks (USTs) must include inspection reports and maintenance records because these documents are essential for ensuring compliance with environmental regulations and for maintaining the safety and integrity of the UST system. Inspection reports provide crucial information about the condition of the tanks and whether they are functioning as intended. Regular maintenance records detail the actions taken to uphold the USTs, addressing any issues that may arise and documenting repairs, replacements, or upgrades. This thorough documentation not only assists in regulatory compliance but also aids in identifying potential problems before they escalate, thereby helping to prevent leaks and environmental contamination.

The other options, such as daily temperature logs, while potentially useful in certain contexts, do not encompass the comprehensive operational documentation required for USTs. Employee attendance records and annual budgets, on the other hand, are unrelated to the immediate operational integrity and safety of the tanks and therefore do not belong in the critical operational records that focus specifically on the functionality and maintenance of USTs.
