Peterson ~~F <br />Less Than 10 Acres ~G~\ h ~•~°`' <br />~ ~~O - ~o~00'`1 <br />Lying in W'/z SW'/a , ~~' <br />Section 36-TSN-R78W-6PM <br />Jackson County, Colorado ~~\o~o\,'' <br />The above named operators submitted a proposal to <br />Colorado Division of Minerals & Geology (March, 1995) to construct <br />a gravel aggregate pit located in a parcel less than 10 acres as <br />described above and as shown in Exhibit "A" attached. Appropriate <br />exhibits, maps and data were attached as required by regulation for <br />mining/reclamation operations of the proposed pit. <br />After further evaluation of the proposed site, the <br />operators have elected to change the direction of mining (mining <br />advancement). By so doing, drainage control is simplified by <br />maintaining the pit bottom drainage gradient opening to <br />("daylighting") the lower land contours. <br />This technique benefits the project by: <br />Eliminating the previously proposed temporary <br />drainage ditch through the site, <br />• More centrally locates the temporary soil piles <br />reducing haul distance and cost. <br />Stage #1 Mining is revised to commence at the lower <br />elevation at the SE extension of the site and daylight pit drainage <br />to the Colorado Highway 14 drainage ditch rather than starting at <br />the NW corner of the site as previously proposed. The following <br />text and related data has been revised to reflect the change in the <br />mining advancement direction. <br />
