EROSION CONTROL MATERIAL INSTALLATION <br /> The outcast waste slope measures 240 ' long by 80 ' wide and <br /> exhibits a 1H : 1V to a 1 . 5H : 1V slope . Surface waste material <br /> varies yet is predominately crusted shales . All slope work will <br /> require the use of ropes. The slope will first be hand scarifed <br /> prior to seeding. Seed (supplied) will be broadcast over the <br /> entire area working from the top to bottom. There will be 3 <br /> different types of erosion control material to be installed on <br /> the slope . The first application will be of a polypropylene mesh <br /> called Polyjute . The portion of the slope which will have the <br /> Polyjute applied will be required to be smoothed of ridges and <br /> rocks which affect uniform contact of the matting to the slope <br /> surface . This will be done prior to seeding. One roll of <br /> Polyjute measures 12 '6" wide X 432 ' long, is 901bs. , and will be <br /> required to be cut in half lengthwise to form two 216 ' rolls for <br /> this application . The Polyjute will be anchored in a 6"w by <br /> 12"deep trench at the top of the slope 3 ' beyond the crest of the <br /> slope . The Polyjute will be stapled on 1 ' spacings with the soil <br /> backfilled and hand compacted . Staples are 6" x 1" x 6" , 11 <br /> gauge U-shaped wire staples . The Polyjute will then be rolled <br /> downslope and stapled on 2 'cc rows . Staples within the rows will <br /> be spaced every 2 . 5 ' . A second roll will be likewise applied <br /> with a 6" edge overlap . The overlap centerline will be stapled <br /> within the general stapling pattern . <br /> Two other erosion control materials will be applied . These two <br /> applications will require a minimum 100 cfm, 100 psi compressor <br /> with 300 ' of 1"d hose . The compressor will be used to apply two <br /> different kinds of a polypropylene fiber product called <br /> Landstrand . The creel dispenser system and air gun will be <br /> supplied by the manufacturers representative . The application of <br /> Landstrand will be performed with no measurable wind and must be <br /> followed by an application of an asphalt emulsion tackifier . The <br /> SS or CSS1 asphalt emulsion must be sequenced to follow the <br /> application of the Landstrand so that an approximate 15 ' length <br /> of Landstrand is applied and is followed by the asphalt <br /> tackifier . During the tackifier application, caution will be <br /> used in not disturbing the Landstrand applied surface with the <br /> tackifier hoses . The Landstrand, once applied, can be walked on <br /> yet there will still be a need for another person to direct <br /> hoses . The seed, Polyjute, staples for the Polyjute, Landstrand <br /> material, applicator gun and creel will be provided by the State . <br /> The contractor will supply the asphalt emulsion and distributer <br /> system (truck, wand , hose) . <br /> MACHINE TIME <br /> In addition to the erosion control material installation , minor <br /> surface preparation work will be needed for revegetation <br /> procedures on the upper coal flat and lower streamside reworked <br /> area. This will primarily involve ripping with a 67 fhp track <br /> machine (D3 or equivilent) . Multiple rippers (3) will be 24" cc . <br /> The machine will also be used in assisting the asphalt <br />
