Op <br />Date: November 2, 2017 <br />To: Michael A. Cunningham, Environmental Protection Specialist <br />Colorado Division of Reclamation Mining and Safety <br />Department of Natural Resources <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Re: City of Golden, Empire Pit No. M-1977-534-AR01 <br />Reclamation Permit <br />Dear Mr. Cunningham: <br />ftic jveD <br />NOV 0 % ?tjI 1 <br />OVftNOFR6C =•r, . <br />N106ANO Er, ' <br />The salt contaminated areas present a challenging problem. If the contamination cannot be removed an <br />infiltration bearer should be installed 18 inches below plants root growth zone then covered with subsoil <br />with adequate clay to slow water and nutrient migration then topped with 6 inches of live natural loam <br />topsoil which includes humus and microorganisms that can sustain plant life before reseeding. May we <br />show you some remaining original stored topsoil that was covered up during the reclamation process? <br />Conceming'to us, about approving Golden's request to release Permit No. M 1977-534-AR01 area <br />surrounding Guanella Reservoir, are the blow out areas on the south bank of the reservoir, see picture 9. <br />They occur during wet years and may continue to enlarge and cause our property on Lincoln Mountain to <br />move causing a landslide. <br />The reseeding should have a success rate of 80 - 90% after germination and lateral stratification after 2 <br />years. Previously no subsoil or clay material was added to the gravel areas to protect the surface soils or <br />amendments from being blown away by wind or leached away by water both of which have happened. It <br />also should not contain foreign materials such as, stones greater than one inch, asphalt, salt and weed <br />seeds and foreign materials. Notes on "What is soil?" from "The Nature and Properties of Soils," <br />Buckman and Braddy, Cornell University, College Text of Edaphology is attached for reference. <br />Larger rocks have been added to areas attempting to control erosion rather than concave sloping for <br />proper flow routing. Areas on the south side of the east partial have not been blended into the hillsides or <br />properly reseeded. This may not inhibit pasturing but was not reseeded and sloped to meet the <br />surrounding topography as required, see picture 8. The removed south fence still has not been <br />reinstalled to complete the enclosure. Why does reclamation not include reinstalling fences and repairing <br />fences damaged or buried during the reclamation? In some areas the grading buried part of the fence up <br />to the bottom wire, see picture 10. <br />Could we meet with you to discuss the Reclamation Process? And would you include us on any <br />correspondence and meetings about the property? Thank you for your consideration. <br />Sincerely, <br />Glenda Guanella Sally Guanella Buckland <br />
