The purpose of a lift station sign-in log is to

• A. Budget lift station visits.
• B. Identify who makes changes in station operation.
• C. Track employee movement for disciplinary actions.
• D. All of the above.

Answer: (B)

The main idea here is accountability: knowing who is on site and who makes changes to a lift station. A sign-in log creates a record of who enters the station and what operational changes or actions they perform. This helps supervisors verify that only authorized personnel are making adjustments, and it provides a clear trail showing when changes were made and by whom. That traceability is crucial for safety, proper maintenance, and troubleshooting, because you can connect any issue or alarm event to the person who made the related change.

This isn’t primarily a budgeting tool, and it isn’t meant to track employees for disciplinary purposes. Those functions are handled through separate processes, so the best answer is that the sign-in log identifies who makes changes in station operation.
