1 <br />l <br /> rebuilt terrace toe. <br />1 RtilP 4.09.1(7) The spoil or waste shall be hauled or <br /> <br />i-- conveyed and placed in horizontal lifts in a controlled <br /> manner, concurrently compacted as necessary to ensure mass <br />- stability and prevent mass movement, covered, and graded to <br /> allow surface and subsurface drainage to be compatible with <br />I the natural surroundings and ensure a long-term static <br />' - safety factor of 1.5. <br /> COMMENT: The waste materials will be hauled and placed in <br />I - horizontal lifts not to exceed a 12 inch loose lift <br /> thickness and compacted at or above 908 of Standard Proctor <br />_ <br />I density and evaluations have shown that final design <br />I - conditions provide factors of safety at or above 1.5. The <br /> 12 inches reported represents a variation from the original <br />- proposed 24 inch lift thickness. This requirement is <br /> proposed since the strength properties of the fill material <br />_ <br />I are an important factor in the stability of the slope. The <br />I - 12 inches is required to achieve the reported properties <br /> utilized in the stability analysis. <br />1 - Rule 4.09.1(8) The final configuration of the fill shall be <br /> suitable for postmining land uses approved in accordance <br />_ <br /> with 4.16, except that no depresions or impoundments shall <br />I - be allowed on the completed fill. <br /> COMMENT: As previously discussed in the response to Rule <br />I 2.08.4, in the August 9, 1984, Technical Revision Request, <br /> there is no change in postmining land use plans. <br />- <br />L Rule 4.09.1(9) The final configuration of the fill shall be <br /> <br />31 <br />
