CISEC Exam-with 100% verified solutions 2024-2025 When working in waterways or wetlands, which permit is required? 404 Permit NPDES National Pollutant Discharge Elimination System Section of CWA (Clean Water Act) to permit stormwater discharges associated with industrial activities per the permit CWA Penalty Types Class I. Negligent Class II. Knowingly = Greater Fines What documents are required onsite? SWPPP CGP Site Map Drawings and Key All inspection reports Any amendments to SWPPP Who is the "Operator" Usually the OWNER of the site, not the contractor, unless authorized by the owner to general contractor to have day-to-day operational control Vertical Projects Homebuilding, smaller residential construction projects Usually multiple subcontractors Requires a lot of housekeeping LDP Land Developing Projects - altering landscape for projects Big Box Projects Commercial buildings Mass grading and mass chaos Limits site access and continually changing (high activity) Linear Priojects Roadways, utilities, and stream corridors Long narrow sites and mass chaos Highly visible with fairly large footprint What is erosion? The process by which soil particles get displaced by the act of wind or water Chemicals added to a mixture to make suspended particles clump together. Cationic (bad), Anionic (good) Who decides the necessary BMPs in the SWPPP for a project? Developer/Designer (not inspector) Types of EC BMPs Placement of pavement, installing landscaping materials, establishing vegetation, construction of homes, culverts/slope drains, diversion channels, ECB and TRMs What is the minimum number of inspections required? Once every 14 days Major things to look for on S&EC plans What is to be installed before grading, as per plan NOTES sections Major discharge points Legends and Changes Inspectors Obligations Review: NOI, SWPPP drawings, and records Observe: SWPPP drawings and onsite BMPs in agreement Inspect: Check for effectiveness of BMPs Report Findings: document findings Know and understand EPA requirements Understand drawings Understand legend, notes, and topography Understand post construction conditions T/F: Inspectors who knowingly falsify information in their report can be fined and possibly imprisoned. True CISEC Motto 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? Builders Of the various types of construction activities, what type will likely keep and inspector the busiest? Linear What type of wind erosion is responsible for the highest amount (50-80%) of soil transport? Saltation In regard to rainfall erosion factors, what's more important, the slope of the land or the length of the flow? Slope T/F: Inspectors must be able to calculate the amount of runoff at the rate of flows that may occur for precipitation events? 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. True T/F: When an inspector identifies an issue, they should mandate to the builder what the builder must do to remedy the situation. False Items to consider about BMPs 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? Inspecting curb and gutter barrier bags 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) 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 Filter bag Riser pipe outlet structure Skimmer outlets Filter Bag Needs replacement when full Inspect for tears, connection leaks Riser pipe outlet structure 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 Skimmer outlets EPA recommended/most effective Is the vent pipe on the top? Keep screen clean Flocculant treatment types Liquid treatment system: water pumped from SCS and mixed with flocculant in treatment chamber then sent to capture system where treated water can be discharged Solid treatment system: runoff dissolved to solid flocculant block (may or may not have a treatment chamber) Diversion channel and berms An EC method used to direct runoff to a specific location Inspection: Will runoff remain within diversion channel? Are embankments stabilized? Is discharge area stabilized? Establishing vegetation #1 method for EC Delineate areas carefully Vegetative buffer strips: used to delineate areas of no construction and sensitive areas Installing sod: instant EC, but requires moisture and proper installation Seeding Save removed topsoil for reapplication later when seeding Inspection: Was the hillside tracked UP & DOWN? Was the soil scarified for seeding? Is fertilizer required? Organic vs. synthetic? Inspecting hydraulic mulch Do "shadows" exist? Was correct amount of material applied? Can you apply it on wet soil? ECB and TRM 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) Criteria for final stabilization Uniform, perennial vegetation to provide 70% or more of vegetative over native to local undisturbed areas Storage containers containing fuel, oil, hydraulic fluids, etc. must be at least BLANK feet from bodies of water 50 In the case of an emergency spill, you must also, within BLANK calendar days of knowledge of the release, provide a description of the release, the circumstances leading to the release, and the date of release 7 Turbidity monitoring requirements Sampling frequency (each day a discharge occurs) Sampling location (all points where dewatering water is discharged) Test methods What is the turbidity benchmark threshold? 50 NTUs unless EPA has authorized the use of an alternate benchmark How many inches of snowfall equals 0.25 inches of rainfall? 3.25" You may reduce the frequency of inspections to BLANK per month for the first month, no more than BLANK calendar days apart, then twice per month until permit coverage is terminated? Twice; 14 Inspection report requirements Inspection date Names and titles of personnel making inspection Summary of inspection findings If inspecting post-rain event, include applicable rain gauge and weather readings If unsafe, not reason and specify locations to which condition applies Must be signed by Operator Must keep copy of reports and retain them for at least 3 years Corrective action deadlines Completion within a day or 7 days For each corrective action taken, you must record the following in a corrective action log: Within 24 hours of identifying corrective action condition, document specific condition and date/time identified Within 24 hours of completing the corrective action, document actions taken to address condition, including whether any SWPPP modifications are required T/F: Contractors are authorized by the CGP to discharge pollutants True: permit authorizes operators to discharge pollutants in accordance with limitations and conditions set forth by the permite T/F: The CGP mandates that qualified inspectors be knowledgeable about S&EC and pollution prevention True T/F: The CGP mandates that erosion due to runoff events must be prevented False T/F: The CGP states that inspections are to occur only during normal working hours True T/F: the CGP does not mandate inspection of equipment storage and maintenance areas False T/F: Since 1998, regulations require permits for Phase I (5 acres or more) projects. Since 2003, permits also required for Phase II (1 or more acres) projects True Where does runoff flow? From high point to low point Offsite flows must be BLANK if they can't be BLANK Treated; diverted What is hydrology? The study of water What are sources of water Precipitation (rain, snow, hail, sleet) Rate of flow depends on what 6 variables? Soil types and roughness Storm intensity and duration Contributing areas Steepness of terrain Length of slope Vegetative cover What is a hydrograph? Picture of runoff X-Axis: flow in cubic feet per second (cfs) Y-Axis: time in minutes Peak = maximum flow during runoff event What is a sedigraph? Represents sediment discharge X-Axis: sediment yield rate Y-Axis: time
