✍️ Sample CEPSCI Questions & Answers
1. When a CEPSCI inspector finds a failed silt fence during an inspection, the first required action is to:
Inspectors must document the deficiency and ensure corrective action is completed within the timeframe required by the permit, often 7 days or within 24 hours for active discharges.
2. What soil amendment is most commonly applied before seeding to improve germination on disturbed sites?
Soil testing guides the application of lime to adjust pH and fertilizer to provide nutrients, both of which are critical for successful seed germination and establishment on disturbed soils.
3. Why is it important to minimize runoff velocity on a construction site?
Runoff velocity directly determines erosive energy; slower flows have less capacity to detach and transport soil particles, reducing overall sediment production and transport.
4. What is 'bioretention' (rain garden) as a post-construction BMP?
Bioretention cells use engineered soil media and native plants to filter stormwater pollutants, reduce runoff volume through infiltration, and attenuate peak flows.
5. How does the slope length factor (L) in the USLE affect predicted soil loss?
As runoff travels down a longer slope, it accumulates more volume and velocity, increasing its erosive energy and the quantity of sediment it can transport.
6. What is the purpose of a diversion dike on a construction site?
Diversion dikes are earthen berms that redirect surface runoff away from disturbed areas or channel it toward a sediment control BMP to prevent uncontrolled runoff.
