CISEC Motto ------CORRECT ANSWER-----------Observe, Inspect, Report, Avoid Mandating 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? ------CORRECT ANSWER----------- Builders Of the various types of construction activities, what type will likely keep and inspector the busiest? ------CORRECT ANSWER-----------Linear What type of wind erosion is responsible for the highest amount (50-80%) of soil transport? ------CORRECT ANSWER-----------Saltation In regard to rainfall erosion factors, what's more important, the slope of the land or the length of the flow? ------CORRECT 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? ------CORRECT 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. ------CORRECT ANSWER----------- True
What are some examples of hydrocarbon materials? ------CORRECT ANSWER-----------Biofuels (gas) Adhesives Pesticides Inspecting fiber rolls ------CORRECT ANSWER-----------Is there a barrier depression? (Check for backfill materials US) Correct diameter used? Are stakes holding it in place? Is spacing of stakes correct? Will barrier contain runoff at ends too? ("Smile") Does barrier divert runoff to a single discharge point? (bad) Never put fiber rolls on bare ground. Efficiency: weak spots exist at point where two fiber rolls meet Rock check structures: Purpose + Requirements ------CORRECT ANSWER-----------For concentrated flows: Slows down runoff to allow for deposition Captures suspended particles along the way Erosion control IF spaced properly Must have a low point (for overflows) and end points must be higher than overflow ("Smile") Check structures as an EC measure ------CORRECT ANSWER-----------Top of the DS structure must be in-line with the bottom of the US structure to minimize erosion Inspecting inlet barriers ------CORRECT ANSWER-----------Look for debris on top of inlet barrier (indicates overflow occurred) Look for sedimentation behind the barrier (lack of sedimentation entirely or uniformly indicates a failure to block at that location)
On grade conditions ------CORRECT ANSWER-----------When runoff is diverted AWAY from drain inlet Inspecting curb and gutter barrier bags ------CORRECT ANSWER----------- Are appropriate sized rocks used in bags? Is there overflow around the bag or underneath? Is the bag too full/compact? Possible tearing? Is there proper spacing between bag and inlet? Sediment Containment Systems (SCS) ------CORRECT ANSWER----------- Purpose: Contain runoff long enough for deposition of suspended particles Must properly trap and contain waters and embankments must be stabilized against erosion Types of drainage methods ------CORRECT ANSWER-----------Filter bag Riser pipe outlet structure Skimmer outlets Filter Bag ------CORRECT ANSWER-----------Needs replacement when full Inspect for tears, connection leaks Riser pipe outlet structure ------CORRECT ANSWER-----------Pipe must have perforations Is size and height of pipe adequate? Does 1 to 2 inch rock surround pipe? Never wrap pipe with fabric, will clog

Inspecting hydraulic mulch ------CORRECT ANSWER-----------Do "shadows" exist? Was correct amount of material applied? Can you apply it on wet soil? ECB and TRM ------CORRECT ANSWER-----------Erosion Control Blanket (usually on hillsides) and Turf Reinforcement Mats (usually on channels) Inspection: Has seed been planted before laying blanket? Is materials anchored in trench? Do sufficient staples exist? (2" apart) Are the edges secured? Can you pull the TRM 6-12"? (not good) Hard armoring ------CORRECT ANSWER-----------Using riprap on hillsides Are animals burrowing in it? Is sediment accumulating on rocks? Is the rock being undercut or collapsing? Cellular confinements ------CORRECT ANSWER-----------Rigid plastic structures where soil can be placed into for vegetative establishment Inspecting hazardous and waste materials ------CORRECT ANSWER-------- ---Are materials stored appropriately/preferably inside?
Are materials labeled? Are the materials disposed of properly? Is there portable containment (concrete washout)? Is there proper protection underneath materials and are they covered? Inspecting portable toilets ------CORRECT ANSWER-----------Is it away from an inlet and off paved roads? Are they anchored well and have secondary containment? Gabions ------CORRECT ANSWER-----------Steel mesh cages filled with rocks, absorb wave energy Since 1992, the EPA has been obligated to publish revised permit requirements every: ------CORRECT ANSWER-----------5 years Currently, Class II Administrative penalties under the CW can result in a max. fine of: ------CORRECT ANSWER-----------$322,0 81 Stabilization - what is considered a "seasonally dry period"? ------ CORRECT ANSWER-----------A month in which the long-term average total precipitation is less than or equal to 0.5 inches If the total amount of land disturbance at any one time is five acres OR LESS, when must stabilization begin? ------CORRECT ANSWER----------- Immediately in any areas of exposed soil where construction activities have permanently ceased or will be temporarily inactive for 14 or more calendar days Installation must be completed no later than 14 calendar day s
