During vertical construction activities, an inspector's job can be quite difficult when you have multiple builders. Who's responsibility is it to install and maintain BMPs in this siutation? - ANSWER--Builders
Of the various types of construction activities, what type will likely keep and inspector the busiest? - ANSWER--Linear
What type of wind erosion is responsible for the highest amount (50- 80%) of soil transport? - ANSWER--Saltation
In regard to rainfall erosion factors, what's more important, the slope of the land or the length of the flow? - ANSWER--Slope
T/F: Inspectors must be able to calculate the amount of runoff at the rate of flows that may occur for precipitation events? - ANSWER--False: designers/reviewers
T/F: When it comes to using flocculants, designers need to have professional skills and expertise in particle removal in order to achieve minimal turbidity of discharge waters. - ANSWER--True
T/F: When an inspector identifies an issue, they should mandate to the builder what the builder must do to remedy the situation. - ANSWER-- False
Items to consider about BMPs - ANSWER--Uses and limitations
Contributing drainage areas
Are BMPs available?
How long will they function?
What pollutants do they treat?
What are some inspector DON'Ts? - ANSWER--Don't redesign SWPPP plans
Don't tell GC how to solve problem

When to install silt fence barriers? - ANSWER--Before construction begins and while construction is occurring
Inspecting silt fence barriers - ANSWER--Are the stakes on the DS side of fabric?
Rock check structures: Purpose + Requirements - ANSWER--For concentrated flows:
Slows down runoff to allow for deposition
Captures suspended particles along the way
Erosion control IF spaced properly
