CESSWI Inspection Procedures and Duties 2

Question 1

During a CESSWI inspection, which document should the inspector review FIRST before visiting the site?

Accepted Answer

The SWPPP and approved site plans

Answer

Reviewing the SWPPP and approved site plans before arriving ensures the inspector knows what controls are required and can assess compliance effectively.

Question 2

A CESSWI inspector notices that a silt fence has been installed but the bottom has not been trenched and backfilled. What is the most appropriate action?

Accepted Answer

Require immediate correction as the fence provides no protection without trenching

Answer

Silt fence effectiveness depends on proper trenching and backfilling to prevent underflow; without it the BMP is non-functional and must be corrected immediately.

Question 3

How frequently must routine inspections typically be conducted on an active construction site under most NPDES permit requirements?

Accepted Answer

At least every 14 calendar days and within 24 hours after a 0.5-inch or greater rainfall event

Answer

Most NPDES construction general permits require inspections every 14 days and within 24 hours of qualifying storm events to catch problems promptly.

Question 4

When documenting inspection findings, which information is LEAST critical to include in the inspection report?

Accepted Answer

Names of all workers observed on site that day

Answer

Worker rosters are not a required component of inspection reports; the critical elements are inspector identity, site conditions, BMP status, and corrective actions.

Question 5

An inspector finds that a sediment basin is more than 50% full of accumulated sediment. What action should be taken?

Accepted Answer

Require sediment removal to restore design capacity before the next storm event

Answer

When a sediment basin reaches 50% capacity its storage volume and residence time are significantly reduced, requiring cleanout to maintain design effectiveness.
