These <br />rills vary in depth of six (6) to approximately eighteen (18) <br />inches. The base of the rills is also crusted and firm. <br />The top of the embankment is generally graded to drain to the <br />northeast. A berm composed of waste material is located at the top <br />of the southwest embankment side slope. This berm is some what <br />irregular and shows signs of water segregation. The northeast <br />and south embankments also have a berm with a drainage ditch which <br />drains the top of the disposal area .to the northeast: The top of <br />the waste area embankment exhibits several small irregularities <br />of the sloped surface , caused by tracking of heavy equipment. <br />The diversion ditches No. 1 and 2 along the refuse area show no: <br />signs of erosion. The bottom of the ditches is mostly of sand- <br />stone. Small amounts of sediment is in the ditches. The east ~ <br />embankment shows signs of recent grading at the upper portion. <br />The slopes are approximately on a 3:1 ratio. <br />RECOMMENDATIONS: (1) That no heavy equipment be used on the slopes <br />to correct the erosion rills. The crusted surface (as is) will <br />have far less sediment dislodgement than if disturbed. (2) The ' <br />rills should receive close observation during the next <br />if decrusted, then placing of straw dissipators will be <br />to control further erosion. (3) The berm located at the <br />slopes is irregular but will cause no determent to the <br />(4) Reclamation of this refuse area should be made at t <br />possible time. <br />quarter and <br />necessary <br />top of the <br />drainage'. <br />he earliest <br /> <br />
