CESSWI SWPPP and Plan Management 5

Question 1

Which of the following best describes 'final stabilization' as defined under the EPA Construction General Permit?

Accepted Answer

All soil-disturbing activities are complete and a uniform perennial vegetative cover of at least 70% density is established, or equivalent non-vegetative cover

Answer

Final stabilization under the CGP requires that all earth disturbance is complete and vegetative cover of at least 70% density (or equivalent) is uniformly established across previously disturbed areas.

Question 2

During a routine SWPPP inspection after a 0.5-inch rainfall, no discharge was observed. The inspector should:

Accepted Answer

Document inspection findings including the no-discharge observation and BMP conditions

Answer

All required inspections must be fully documented regardless of discharge conditions, including observations of BMP status and the no-discharge finding.

Question 3

A SWPPP requires inspections every 7 days and within 24 hours after a 0.25-inch rain event. During a week with two qualifying rain events, the minimum number of required inspections is:

Accepted Answer

3

Answer

The two post-storm inspections (within 24 hours of each event) satisfy the weekly requirement if they occur within the 7-day interval, resulting in a minimum of 2 inspections for that week.

Question 4

Which element distinguishes a pollution prevention plan from a standard erosion control plan within a SWPPP?

Accepted Answer

Pollution prevention plans address non-sediment pollutants such as concrete washout, fuels, and chemicals

Answer

Pollution prevention measures address non-sediment construction pollutants (fuels, concrete, paints, chemicals), while erosion control focuses on soil loss and sedimentation.

Question 5

Which scenario would most likely require an operator to obtain individual NPDES permit coverage rather than coverage under a Construction General Permit?

Accepted Answer

A site with a history of permit violations and a significant potential for water quality harm

Answer

EPA or a state agency may require individual permit coverage when a site poses a significant risk to water quality, such as a pattern of violations or proximity to sensitive resources.
