In MS4 operations, what is the primary goal of the Annual Inspection/Monitoring Program?

• A. To measure the cost of compliance
• B. To identify illicit discharges, failing BMPs, and noncompliant practices, and implement corrective actions with proper documentation.
• C. To perform only visual audits
• D. To replace BMPs on a fixed schedule regardless of condition

Answer: (B)

The main idea of the annual inspection/monitoring program is to actively identify problems that affect stormwater quality—such as illicit discharges, failing BMPs, and practices that don’t meet permit requirements—and to fix them, with thorough documentation of what was found and what actions were taken. This approach targets the sources of pollution and ensures the system continues to meet regulatory obligations, while also providing a clear record for accountability and future improvements. Visual audits alone can miss hidden or evolving issues, and measuring cost of compliance doesn’t address actual pollution sources or performance. Replacing BMPs on a fixed schedule without regard to their condition or effectiveness can waste resources and fail to address current problems.
