A sewer-use ordinance should specify the personnel performing

• A. Cleaning of the main lines
• B. Repairing of broken pipe
• C. Sealing of leaky joints
• D. Monitoring

Answer: (D)

Monitoring responsibilities are the element a sewer-use ordinance should designate to ensure proper regulation and enforcement. An ordinance needs to specify which personnel are authorized to conduct monitoring—sampling, data collection, inspection, and reporting of discharges. This creates accountability, ensures consistency and data quality, and supports compliance with permit requirements. Maintenance tasks like cleaning main lines, repairing pipes, or sealing joints are routine field work typically handled by maintenance crews, not the focus of an ordinance's designation for regulatory oversight.
