1. The primary purpose of the NPDES Construction Site Runoff Control
requirement is to:
A. Increase construction speed by reducing inspections
B. Prevent pollutants from entering waters of the United States from
construction activities
C. Eliminate all stormwater discharges from construction sites
D. Replace all local erosion control regulations
Answer: B. Prevent pollutants from entering waters of the United States
from construction activities
,The NPDES Construction Site Runoff Control requirement focuses on
controlling pollutants in stormwater discharges caused by land disturbance
activities.
2. NPDES stands for:
A. National Pollution Discharge Evaluation System
B. National Permit for Environmental Development Standards
C. National Pollutant Discharge Elimination System
D. Natural Pollution Drainage Elimination Strategy
Answer: C. National Pollutant Discharge Elimination System
NPDES is the federal permitting program designed to regulate pollutant
discharges into waters of the United States.
3. Construction sites generally require NPDES stormwater permit
coverage when they disturb:
A. Less than 100 square feet of land
B. One acre or more of land, including related activities
C. Only paved surfaces
D. Only government-owned property
Answer: B. One acre or more of land, including related activities
,Federal stormwater regulations commonly require permits for construction
activities disturbing one or more acres of land.
4. The main pollutant generated by soil disturbance at construction sites
is:
A. Chlorine
B. Sediment
C. Oxygen
D. Nitrogen gas
Answer: B. Sediment
Sediment from exposed soil is one of the most common pollutants in
construction stormwater runoff.
5. A Construction Stormwater Pollution Prevention Plan (SWPPP) is
developed to:
A. Increase project costs
B. Identify and control potential pollutant sources
C. Replace construction drawings
D. Eliminate contractor responsibilities
Answer: B. Identify and control potential pollutant sources
, A SWPPP outlines best management practices and procedures to minimize
stormwater pollution.
6. Best Management Practices (BMPs) are:
A. Legal penalties for violations
B. Construction schedules
C. Measures used to prevent or reduce pollution
D. Types of construction equipment
Answer: C. Measures used to prevent or reduce pollution
BMPs include structural and operational practices that control erosion,
sediment, and other pollutants.
7. The first step in effective erosion control is:
A. Allowing soil to remain exposed
B. Stabilizing disturbed areas
C. Removing all vegetation
D. Increasing runoff velocity
Answer: B. Stabilizing disturbed areas
Preventing soil erosion at the source reduces the amount of sediment
available for transport by stormwater.
8. Which practice is considered a perimeter control BMP?
