Visual Monitoring is required for which of the following?

• A. All storm water discharge sites
• B. All sites subject to this General Permit
• C. Sites with erosion control plans
• D. Sites with no discharge

Answer: (B)

Visual Monitoring is a required activity for every site that falls under this General Permit. The permit mandates that operators visually observe stormwater discharges and the effectiveness of erosion and sediment controls at all sites covered by the permit, during and after rainfall, and document what is seen. This broad application ensures any emerging issues are detected and addressed promptly, and it provides a consistent record of compliance in the SWPPP. It isn’t limited to sites with an erosion control plan, nor to sites that are actively discharging, nor to sites with no discharge—the requirement follows the site’s permit coverage.
