This course is approved for renewal of Level 1A/1B OR Level II GASWCC Certification.
This course is for Level 1A, Level 1B, and Level II GSWCC certified personnel in Georgia as well as all other interested parties. By far, silt fences are the most commonly used temporary sediment barrier to trap sediment in surface (sheet) flow. Silt fence is manufactured from geotextile filter fabric that allows water to pass through while trapping soil particles long enough for them to settle. Georgia has two classes of silt fence. The Sd1-S (Sensitive) fence also known as Type C silt fence.
It is installed in areas that require additional protection such as state waters, wetlands or where runoff velocity is high. Sd1-S fences require support spacing must be no greater than 4 feet center to center. The Sd1-NS (Non-sensitive) fence also known as the Type A or Type B silt fence. It is used in other areas. Sd1-NS fences require a support system spacing of no greater than six (6) feet on center. Regardless of the type, both require stakes, wood or metal to be driven 18 inches into the ground.
The course will present 3 basic installation methods (manual, trenching and slicing). Bypassing obstacles while installing sediment barriers (silt fences in particular) can be a real challenge, the course will cover possible solutions as well as methods that have proven successful on slopes, adjacent to graded areas, sensitive and non-sensitive areas. Finally, maintenance is very important, effective methods to clean out and even improve silt fence effectiveness will be discussed.
CLASS EXERSIZE:
The attendees will be divided into small groups. Each group will be issued a piece of silt fence, (new or previously used, or damaged). Using the silt fence tray, the group will pour a quantity of sediment into the tray and discuss the respective effectiveness and reduction of turbidity after the water passing through the fabric is collected and analyzed by a turbidimeter for NTUs.
