The areas inspected and approved for placement <br />are shown in Figure 2. <br />B) Slope Contouring <br />1) VLF <br />Slope contouring was performed in the following areas; between stations A36+00 (+/-) and <br />A41+50 (+/-), approximately 0 to 200 feet left of centerline; between stations C1+00 (+/-) and <br />C7+00 (+/-), approximately 50 to 100 feet left of centerline; between stations E20+00 (+/-) and <br />E22+50 (+/-), approximately 150 feet left of centerline to 150 feet right of centerline and <br />between stations H0+00 (+/-) and H10+00 (+/-), approximately 0 to 300 feet right of <br />centerline. Slope contouring was performed using various CAT dozers and various CAT <br />excavators. The material generated as the cut progressed was pushed down the slope. <br />VLF Weekly Report WE 07.10.10.D <br />
