Buffer requirements apply if your project's earth-disturbing activities will occur within 50 feet of a surface water.You may group your E&S controls on your form if you have several of the same type of controls (e.g.,you may group "Inlet Protection Measures", "Perimeter Controls",and "Stockpile Controls"together on one line), but if there are any problems with a specific control,you must separately identify the location of the control,whether repairs or maintenance or corrective action are necessary,and in the notes section you must describe the specifics about the problem you observed. Repairs or Other Maintenance Needed? Answer"yes" if the E&S control requires a repair of any kind (due to normal wear and tear,or as a result of damage) or requires maintenance in order for the control to continue operating effectively.At a minimum, maintenance is required in the following specific instances: (1) for perimeter controls,whenever sediment has accumulated to or more the above-ground height of the control (CGP Part 2.1.2.2.b); (2) where sediment has been tracked-out onto the surface of off-site streets or other paved areas (CGP Part 2.1.2.3.d); (3) for inlet protection measures,when sediment accumulates,the filter becomes clogged,and/or performance is compromised (CGP Part 2.1.2.9.b);and (4) for sediment basins, as necessary to maintain at least'/2 of the design capacity of the basin (CGP Part 2.1.3.2.b). Note: In many cases, "yes" answers are expected and indicate a project with an active operation and maintenance program.You should also answer"yes"if work to fix the problem is still ongoing from the previous inspection. Corrective Action Needed? Answer"yes"if during your inspection you found any of the following conditions to be present (CGP, Part 5.2.1): (1) a required E&S control was never installed,was installed incorrectly,or not in accordance with the corresponding CGP Part 2 or 3 requirement; (2) you become aware that the inadequacy of the E&S control has led to an exceedance of an applicable water quality standard;or (3) EPA requires corrective action for an E&S control as a result of a permit violation found during an inspection carried out under Part 4.2.If you answer"yes",you must take corrective action and complete a corrective action report,found at www.epa.gov/nodes/stormwater/swpop.Note: You should answer"yes"if work to fix the problem from a previous inspection is still ongoing. Date on Which Maintenance or Corrective Action First Identified? Provide the date on which the condition that triggered the need for maintenance or corrective action was first identified.If the condition was just discovered during this inspection,enter the inspection date. If the condition is a carryover from a previous inspection,enter the original date of the condition's discovery. Notes For each E&S control and the area immediately surrounding it, note whether the control is properly installed and whether it appears to be working to minimize sediment discharge.Describe any problem conditions you observed such as the following,and why you think they occurred as well as actions (e.g.,repairs, maintenance,or corrective action) you will take or have taken to fix the problem: 1.Failure to install or to properly install a required E&S control 2.Damage or destruction to an E&S control caused by vehicles,equipment,or personnel,a storm event,or other event 3.Mud or sediment deposits found downslope from E&S controls 4.Sediment tracked out onto paved areas by vehicles leaving construction site 5.Noticeable erosion at discharge outlets or at adjacent streambanks or channels 6.Erosion of the site's sloped areas (e.g.,formation of rills or gullies) 7.E&S control is no longer working due to lack of maintenance For buffer areas, make note of whether they are marked off as required,whether there are signs of construction disturbance within the buffer,which is prohibited under the CGP, and whether there are visible signs of erosion resulting from discharges through the area. If repairs, maintenance,or corrective action is required, briefly note the reason.If repairs, maintenance,or corrective action have been completed, make a note of the date it was completed and what was done.If corrective action is required, note that you will need to complete a separate corrective action report describing the condition and your work to fix the problem.
