Under the EPA's Construction General Permit (CGP), how soon after a qualifying storm event must an inspection be completed?
Answer: Within 72 hours of the storm ending
The EPA CGP requires post-storm inspections to be completed within 72 hours after the end of a qualifying storm event of 0.25 inches or more.
Which area of a construction site typically receives the most scrutiny during a site inspection for sediment loss?
Answer: Downslope perimeter controls and discharge points
Downslope perimeter controls and discharge points are where sediment leaves the site, making them the highest-priority inspection locations.
What is the recommended minimum slope for a gravel construction entrance/exit pad to promote vehicle tire cleaning?
Answer: 1-2% toward the site interior to prevent tracking toward the road
A slight 1-2% slope toward the site interior helps direct drainage away from the public road and encourages tire cleaning as vehicles depart.
When inspecting silt fence, which defect indicates that the fence is likely to fail hydraulically during a storm?
Answer: Geotextile fabric is torn at a post connection point allowing a gap
Tears in the geotextile fabric at post connections create gaps through which sediment-laden water can flow unfiltered, representing a critical failure point.
During a dry-weather inspection, an inspector notices a trickle of murky water flowing from a storm drain that is not connected to any known dewatering activity. What should the inspector do first?
Answer: Trace the flow upstream to identify the illicit discharge source and document findings
Dry-weather flows of turbid water suggest an illicit discharge, which must be traced to its source and documented for reporting under the SWPPP.
What is the purpose of recording the name and signature of the inspector on every inspection report?
Answer: To certify that the inspection was conducted by a qualified individual and the information is accurate
Inspector signature certifies that the inspection was conducted by a qualified person and that the reported information is accurate, which is a legal certification.
A bioretention cell on a construction site is filling with sediment during the construction phase. What is the standard practice to protect it?
Answer: Install temporary bypass measures to divert construction runoff around it until the site is stabilized
Permanent stormwater features like bioretention cells should be bypassed or protected during construction to prevent premature clogging with construction sediment.
