'•~ <br /> <br />~ST~ATE OF COLORADO <br />Land Reclamation Board <br />Department of Natural Resources <br />1845 Sherman Street <br />Denver, Colorado 80203 <br />ADENDUM TO: Specification Aggregates, Inc. <br />Application for Conversion of Existing <br />Permit to Permit for Life of the Mine <br />OVERBURDEN: <br />In paragraph 10. h. of the Application, the narration for <br />Exhibit B paragraphs e. and g., narration for Exhibit C, and <br />in a portion of Exhibit N references are made regarding the <br />overburden of the affected area. Overburden, as it applies <br />to this mining operation and in accordance its definition in <br />Title 34, Article 32 Section 103 paragraph (11) will almo:~t <br />in its entirety be consumed in the manufacture of constru~:tion <br />materials. Consequently, there is in essence vertually n~~ <br />overburden of consequence which is or will become a factor in <br />this mining operation. The average depth of material lying above <br />the crystalline rock formation is less than 12 inches. T};ere are <br />a few isolated pockets of soil, which consitutes a small )part of <br />the overburden, that are being removed and stock piled for future <br />use as top soil. Generally these areas provide less than two <br />feet of material suitable for removal. This soil is intermixed, <br />in earring quantities, with decomposed crystalline rock. It is <br />hoped that perhaps a 1000 tons of this material can be accumulated <br />during the life of the mine. <br />PTH AND THICKNESS OF THE ORE BODY: <br />The depth and thickness of the ore body "Precambrion Cryst:aline <br />Rock" is infinite, but for the purpose of this mining operation <br />the reclamation plan proposes to reduce the existing surface <br />elevation to a nominal elevation of approximately 6500 feet in <br />the extraction area. This will provide a maximum thickness of <br />about 400 feet and a minimum thickness of 20 feet of material <br />to be extracted. Paragraphs 10. h., 10. j., 11. a. ("Exhibit <br />A", "Exhibit A-1" and "Exhibit A-2") and the narr,s tion fox <br />marked "Exhibit B-1", of the application, each a1:Lude to the <br />depth and thickness of the ore body. <br />PRESENT VEGETATION MAPS: <br />A vegetation map marked "Exhibit N-1" is submitted herewith in- <br />dicating the predominate vegetation species. This map has been <br />prepared with assistanCe•and info}mation provided by the <br />United States Departme~Yrt'.of Agri G~lture, Soil Con~;ervation <br />Service. ~ ~ ~ - ~•`+' <br />:; _ <br />Ph AND CONDUCTIVITY OF~=S FjIL: ... ^. <br />Also provided by the So'i~l• Conser'~-ation Service is the information <br />that the soils within the affected-area have a Ph of 6.1 to 7.8 <br />and Conductivity of <br />
