Production and application of biodegradable sediment control device

Abstract

An elongated web of flexible material having a covering of excelsior across a portion thereof has an elongated edge portion uncovered. The elongated covered portion is folded over upon itself a number of times, and the elongated uncovered side portion (a tail) are wound upon a roll for utilization after unrolling, as a sediment barrier, properly staked into the ground.

1 - 17 . (canceled) 
     
     
         18 . An “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement having a longitudinal axis, the elongated sediment control arrangement being comprised of:
 a biodegradable, normal-to-ground arrangement of soil trapping, longitudinally extending multi-folded, excelsior treatment material coated body portion, and 
 a biodegradable ground parallel arrangement, longitudinally elongated excelsior treatment material free tail portion, wherein both the elongated excelsior treatment material coated body portion and the tail portion form a single L-shape and cross-section in their ground secured configuration and wherein the normal-to-ground arrangement of excelsior treatment material coated portion has a plurality of spaced apart stake receiving pockets along one side thereof. 
 
     
     
         19 . The “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement as recited in  claim 18 , wherein the multi-folded excelsior treatment material coated body portion is folded onto itself at least three times. 
     
     
         20 . (canceled) 
     
     
         21 . The “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement as recited in  claim 19 , wherein the multi-folded elongated excelsior treatment material coated body portion consists of a 180° flip around its longitudinal axis. 
     
     
         22 . The “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement as recited in  claim 18 , wherein the tail portion is ground securable. 
     
     
         23 . The “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement as recited in  claim 22 , where in the ground securable elongated biodegradable, temporary sediment control arrangement is formed of a plurality of longitudinal folds. 
     
     
         24 . The “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement as recited in  claim 23 , is comprised of three folds of excelsior treated material. 
     
     
         25 . The “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement as recited in  claim 24 , wherein the stake receiving pockets are attached by adhesive. 
     
     
         26 . The “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement as recited in  claim 25 , wherein the tail portion is the only excelsior free portion of the sediment control arrangement free. 
     
     
         27 . The “L” shaped ground securable elongated biodegradable, temporary, sediment control arrangement as recited in  claim 26 , wherein the material comprising the elongated biodegradable, temporary, sediment control arrangement is of temporary “L” shape in cross-section during manufacture.
