<br />EXHIBIT D - MINING PLAN <br />~ (Part of Exvlanation of Request on County Anolication) <br />The permit area is 45.48 acres in size and will be excavated to <br />provide sand material for off-property projects. The excavation <br />will proceed from south to north in four phases. Except when the <br />Creek runs after storm events, the operation will be a dry pit <br />~ operation. Equipment is stored outside of the dry creek bed area. <br />When the Creek flows, the operation ceases until the area drys-up <br />so excavation can be continued. <br />The County has imposed a condition that the operation be completed <br />on or before July 20, 2002. If the operation is not expected to be <br />• completed on that date, an extension of the County's approval will <br />be processed during the spring or early summer of 2002. Beginning <br />will be determined by when the two needed permits IMLRB and County) <br />are issued, and an available user desires the material. The <br />operation is expected to last up to 10 years. <br />Since there is no surface topsoil, no surface material will be <br />~ stripped for later revegetation. For each phase, excavation will <br />proceed from south to north. Material will be excavated using <br />backhoes and other equipment to a maximum depth of approximately <br />15-30'. It may be loaded directly into trucks, or stockpiled. The <br />floor of the excavation will have a minimum slope of 2%. The side <br />slopes will not be left steeper than 2 to 1 temporarily, and 4 to <br />~ 1 for final reclamation. Other restrictions on mining imposed by <br />the County are as follows: <br />1. No mining will be allowed south of access road <br />(approximately 100± feet, and should any erosion occur <br />from flood events, this area will be immediately restored <br />to its former condition. This requirement has also been <br />~ added to the "Pre-Mining and Mining Plan Map". <br />2. No stockpiles of materials shall be allowed within 50 <br />feet of the centerline of West Bijou Creek (100 feet <br />total), and all stockpiles outside of this area shall be <br />orientated in a north-south direction so as to not impede <br />~ or divert stormwaters. Prior to the start of mining, the <br />100 foot non-stockpile storage area shall be be staked to <br />provide an indicator for placement of stockpiles. <br />3. Prior to starting operations and prior to the start of <br />each phase, the County must issue a "Notice to Proceed" <br />so that all applicable County conditions and <br />~ stipulations, and the reclamation of the previous phase <br />can be verified. <br />These restrictions were based on the Floodplain/F1oodPlain Report <br />required by the County, a copy of which is included in the last <br />section of this submittal titled "Other Information" . <br />~~ <br />~~ <br />
