CESSWI Safety and Communication 4 — Questions and Answers
Question 1: What information is typically required when logging a rainfall event in storm water inspection records?
- Only the date of the rain
- Date, estimated or measured precipitation amount, and whether an inspection was triggered (Correct answer)
- The names of all workers present during the rain
- A description of cloud types observed
Correct answer: Date, estimated or measured precipitation amount, and whether an inspection was triggered
Rainfall logs must capture date, precipitation amount, and whether the event triggered an inspection under permit requirements to demonstrate compliance.
Question 2: Which scenario most likely triggers a post-storm inspection requirement under typical NPDES construction permits?
- Any cloudy day with no precipitation
- A rainfall event meeting or exceeding the permit-specified threshold (commonly 0.25–0.5 inches) (Correct answer)
- Temperatures below freezing
- Completion of concrete pours
Correct answer: A rainfall event meeting or exceeding the permit-specified threshold (commonly 0.25–0.5 inches)
Most construction general permits specify a rainfall depth threshold (often 0.25 or 0.5 inches) that triggers a required inspection within a defined timeframe afterward.
Question 3: What is the primary purpose of maintaining a chain of custody for water quality samples collected during a storm water inspection?
- To identify who is to blame for pollution
- To ensure sample integrity and legal defensibility by documenting all handlers from collection to laboratory analysis (Correct answer)
- To satisfy laboratory billing requirements
- To determine the cost of treatment
Correct answer: To ensure sample integrity and legal defensibility by documenting all handlers from collection to laboratory analysis
Chain of custody documentation preserves sample integrity and ensures results are legally defensible by tracking every person who handled the sample.
Question 4: A CESSWI inspector working solo in a remote area of a large construction site should implement which safety practice?
- Complete inspections as quickly as possible without checking in
- Establish a check-in schedule with a supervisor and carry a communication device (Correct answer)
- Avoid all remote areas and only inspect areas near the site entrance
- Inspect only during peak construction hours when many workers are present
Correct answer: Establish a check-in schedule with a supervisor and carry a communication device
Solo workers in remote areas must establish scheduled check-ins and carry reliable communication devices to ensure timely response if an accident occurs.
Question 5: In the context of SWPPP communication, what does the acronym 'NOI' stand for?
- Notice of Inspection
- Notice of Intent (Correct answer)
- Notification of Incident
- Notice of Infraction
Correct answer: Notice of Intent
NOI stands for Notice of Intent, the document submitted to the permitting authority to obtain coverage under a general NPDES permit before construction begins.
Question 6: When an inspector uses photographic documentation, what information should accompany each photo in the inspection record?
- Only the file name generated by the camera
- Date, time, location (station or GPS), subject description, and direction of view (Correct answer)
- The inspector's personal opinion of the BMP's effectiveness
- The contractor's name only
Correct answer: Date, time, location (station or GPS), subject description, and direction of view
Each photo should be accompanied by date, time, specific location, description of what is depicted, and viewing direction to be useful in enforcement or legal proceedings.
Question 7: What action should a CESSWI inspector take if they encounter an aggressive or threatening response from a contractor during an inspection?
- Physically restrain the contractor until the situation is resolved
- Calmly disengage, ensure personal safety, and report the incident to the supervisor and regulatory agency as required (Correct answer)
- Abandon the inspection permanently and submit no report
- Escalate the confrontation to establish authority
Correct answer: Calmly disengage, ensure personal safety, and report the incident to the supervisor and regulatory agency as required
Inspector safety takes priority; disengaging calmly and reporting the incident through proper channels protects both the inspector and the integrity of the regulatory process.
