Background description of company and its products:
	Silt-Saver, Inc. established in 1999. It has been our goal to produce high-quality, high-performance products that put the word "Best" in Best Management Practices (BMPs). We have achieved our goal with our sediment control products.
Recommended Uses-Primary: Miscellaneous
Recommended Uses-Alternate: Miscellaneous
Outstanding Features or Advantages Claimed:
	WBSF 2-Stage is specifically designed for the practice of vertical sediment control. It addresses sediment retention and the controlled release of stormwater runoff that transport the sediment. Offering integrated reinforcing elements for linear strength and attachment points. Therefore, it traps the sediment, releases the water and has the structural integrity to withstand the forces of runoff.
General Composition of Material:
	WBSF 2-stage is manufactured from high-tenacity polypropylene yarns, which are woven into a dimensionally stable network in such a manner that the yarns retain their relative position to one another. WBSF 2-stage resists ultraviolet deterioration and biological degradation and is inert to most naturally encountered soil chemicals, alkalis, and acids. The WBSF 2-stage fabric has an innovative design to balance the structural integrity, controlled stormwater release, and sediment retention required to optimize sediment retention. The design integrates high tensile strength bands woven into the fabric that provide attachment points to prevent fasteners from pulling through the fabric and linear support to distribute the load as opposed to concentrating the load at a single post based on elevation. These design features provide superior structural integrity necessary for a geotextile to be effectively used as a vertical, permeable interceptor designed to remove suspended soil from overland stormwater runoff. Unlike conventional fabrics contemplated in material specifications like AASHTO M 288-22, this geotextile fabric is woven with 2 distinct apparent opening sizes. The lower, first stage, provides 12-18 inches of a nominal 50 sieve fabric to enhance sediment filtration and deposition for smaller rain events or drainage areas with lower volumes of stormwater runoff. The upper, second stage, provides 12 inches of a nominal 20 sieve fabric to enhance the release of stormwater runoff while controlling the rate of runoff through the fabric and distributing the flow over a wider surface area during larger rain events or drainage areas with substantial volumes of runoff. This greatly reduces the hydrostatic pressure concentrated at a single point which can lead to undermining, overtopping, and catastrophic failure of the sediment barrier. Kentucky Department of Highways does not maintain a list of approved sediment control fabrics. Standard specification 827.08 (C) requires the geotextile fabric conform to AASHTO M 288. In addition, the fabric provided is to have a height of 3 feet. Studies conducted by Auburn University have determined the optimum impoundment height for a sediment barrier like silt fence is 12 to 18 inches. Impounding higher volumes of water increases the potential for undermining, overtopping, and catastrophic failure and does not significantly increase sediment retention. The International Erosion Control Association design standard reinforces the need for designers to consider methods of dewatering to prevent these common failures. In summary, the WBSF 2-Stage does not meet the strict material specification detailed in AASHTO M 288-22 because it is not a 30-sieve fabric over the full height of the fence. This is by design. Years of experience have proven there is no correlation between material specifications and effective performance of geotextile fabrics as sediment barriers in actual field application. We request the Kentucky Department of Highways consider new products that are better designed to control runoff and reduce sediment loss during construction. There can be no improvements to protecting the waters of the United States if outdated material specifications are allowed to stymie innovation.
