3 A nation that destroys its soils, destroys itself. U.S. President Franklin D. Roosevelt, 1937 Common Erosion Problems The impact of erosion on the environment can be serious and potentially irreversible. Our landscape, water sources, agricultural resources and wildlife can all be affected by the devastation. Billions of dollars are spent each year to manage the effects of erosion. Slopes are washed away by storm water runoff, channels are filled with sediment, shorelines can be altered forever and topsoil can be lost to harvests. Designers, specifiers and installers can prevent much of this destruction by using the latest developments in erosion control. Western Excelsior provides the products and expertise landowners, contractors and government agencies need to protect natural resources from land and soil loss. Western Excelsior solutions save many natural resources, save time and save money. Erosion Control Regulation In March 2003, the U.S. Environmental Protection Agency implemented Phase II of the National Pollutant Discharge Elimination System (NPDES). Currently, the regulations apply to virtually all construction activities. Any construction site of one acre or more must comply with the Phase II regulations. NPDES requirements pertain to simple erosion control on slopes, drainage channels, shorelines and the control of sediment. State and local officials also regulate the control and release of in-situ soil material. Western Excelsior is approved for use in virtually every state and for all types of projects. Western Excelsior has the expertise to aid in compliance with NPDES and other regulations. Further, Western Excelsior manufactures the products necessary to fulfill the requirements for any erosion problems contractors, designers and specifiers face. Best of all, Western Excelsior solutions are complete and cost effective w w w. w e s t e r n e x c e l s i o r. c o m 2

4 Why use an erosion control blanket? Accelerated global soil erosion decimates 12 to 15 million acres of land per year, and the costs to society are immeasurable. Erosion is a naturally occurring process on all lands, with effects ranging from topsoil degradation to gullies and shoreline degeneration. Soil erosion can develop practically unnoticed, over time, or it can occur at an alarming rate, with potentially catastrophic consequences. A Rolled Erosion Control Product (RECP) is a matrix consisting of various organic or inorganic materials confined by netting, stitching and/or geo-composites. When properly placed, RECPs prevent loss of soil and aid in the establishment of healthy vegetation, to prevent erosion in the future. sediment into streams, lakes and rivers. Western Excelsior products are engineered to provide variable longevity, allowing for degradation quickly after placement, or a permanent presence. All Western Excelsior products serve as a mulching layer and the EXCEL PP5 series of Turf Reinforcement Mats provide permanent enhancement of vegetation stability. For more information about erosion control, visit the The Erosion Control Technology Council (ECTC) Web site at Western Excelsior products are engineered to control erosion on slopes, drainage channels and shorelines; establish vegetation in bare areas; reinforce the stems and roots of vegetation; and control the release of Environmental Benefits of Erosion Control WESTERN EXCELSIOR s erosion control products are specifically engineered to lessen the impact of soil erosion due to wind or water and provide a mulching layer for the establishment of vegetation. High-Altitude Rocky Mountain Aspen yield an outstanding excelsior for this purpose. Typically harvested from elevations over 8,000 feet and in a semi-arid climate, Rocky Mountain Aspen-produced excelsior consists of strong, durable and absorbent fibers. Use of excelsior as erosion and sediment control completes the cycle from harvesting to re-growth. Recycling natural components in the establishment of new vegetation to mitigate erosion results is the highest form of environmental stewardship w w w. w e s t e r n e x c e l s i o r. c o m

6 THE EXCELSIOR STORY ASPEN EXCELSIOR was an original erosion control material. One of the earliest materials manufactured, evaluated and specified for erosion control, excelsior has proven to provide excellent erosion control, superior mulching and unique and useful longevity. Excelsior achieves excellence in erosion control by bonding with the soil surface when wetted. Excelsior fibers interlock uniquely and adhere to one another, protecting the soil surface. Further, the open matrix and superior mulching of excelsior allows for easy and rapid establishment of vegetation. Excelsior is the final step in the life cycle of an Aspen tree. After it is harvested, excelsior is applied to the soil surface and wetted to facilitate vegetation. Then it degrades, leaving no trace and only clean water. Excelsior has been used in countless projects, providing erosion protection and mulching unmatched by any other degradable material w w w. w e s t e r n e x c e l s i o r. c o m

10 PERMANENT Permanent Turf Reinforcement Mats (TRMs) provide the highest level of erosion protection of all rolled products. The EXCEL PP5 series of TRMs are fully synthetic and designed to be utilized for immediate erosion control and long-term turf reinforcement. EXCEL PP5 TRMs provide tensile strength, flexibility and porous loft to form an outstanding channel liner, slope protection and growth medium. EXCEL PP5 TRMs are ideal for large channels and steep slopes requiring the highest level of protection. EXCEL PP5 TRMs have been utilized on many projects, typically to provide permanent reinforcement of the established vegetation. For instance, the 10-year, $5.1 billion expansion of Atlanta s Hartsfield Airport required the placement of over 100,000 square yards of EXCEL PP5 material to mitigate the forces of erosion. As construction activities displaced hundreds of thousands of cubic yards of soil each day, slopes and channels were lined with EXCEL PP5 to stabilize the final grade. The outstanding utility, performance and value of the EXCEL PP5 provided project solutions to the design and contractor team w w w. w e s t e r n e x c e l s i o r. c o m
