CESSWI Inspection Procedures and Duties 5

Question 1

Which scenario represents a 'significant non-compliance' event that typically requires expedited regulatory reporting?

Accepted Answer

An unpermitted discharge of sediment-laden water to a water of the United States

Answer

An unpermitted discharge to waters of the US is a significant non-compliance event under most NPDES permits, requiring immediate corrective action and often accelerated reporting to the regulatory agency.

Question 2

When inspecting a sediment retention pond outlet structure, what is the inspector checking by examining the riser barrel and anti-seep collar?

Accepted Answer

Whether seepage or piping through or around the embankment could cause structural failure

Answer

Anti-seep collars are designed to prevent piping failures along the barrel; inspectors check for signs of seepage, settlement, or erosion around the outlet structure that could indicate embankment instability.

Question 3

A CESSWI inspector identifies a BMP deficiency during an inspection. The timeframe for corrective action under most construction general permits is typically:

Accepted Answer

Within 7 calendar days for most deficiencies, with some requiring immediate action for active discharges

Answer

Most CGPs require non-emergency deficiencies to be corrected within 7 calendar days, while active discharges or high-risk conditions may require immediate action.

Question 4

The inspector's duty regarding confidentiality of inspection findings primarily means:

Accepted Answer

Inspection records are typically public documents but should not be selectively shared to benefit one party over another

Answer

Inspection records under NPDES programs are generally public documents subject to disclosure laws; the inspector must handle them objectively without favoritism to any party.

Question 5

When assessing the effectiveness of a fiber wattle (straw roll) installed on a slope, which observation indicates the BMP is performing correctly?

Accepted Answer

The wattle is anchored securely, perpendicular to slope flow, with no undercutting or bypass channels

Answer

A properly installed fiber wattle is staked perpendicular to flow direction with ends turned uphill to prevent bypass, and must show no signs of undercutting or flow routing around it.
