Which of the following is considered a control measure for industrial discharges?

• A. Enforce sewer use ordinances
• B. All of the Above
• C. None of the Above
• D. Monitoring

Answer: (B)

Controlling industrial discharges relies on actions that both limit what can be released and verify that limits are being met. Enforcing sewer-use ordinances is a control measure because it sets rules for what can be discharged, prevents illicit connections, and provides the authority for enforcement actions when limits are violated. Monitoring is a control measure because it provides the data to confirm permit compliance, detect exceedances, and guide corrective actions. Since both enforcement and monitoring are essential parts of controlling industrial discharges, the best choice is the one that includes both. One element alone works, but without the other you’d have limited ability to prevent or detect problems.
