This submittal includes three copies <br />of an annotated Ownership map at the same scale as the other map exhibits. <br />Exhibit C - Pre-mining and Mining Plan Map - This exhibit has been revised to provde -the <br />requested label for the natural gas pipeline. The previously submitted text documents included a <br />description of the material crushing and stockpiling area as being located at the existing 110c site. <br />The enclosed 3 copies of the mining map exhibit has been labeled to show that. <br />Exhibit D, Part f, ii - Underlying the surficial sand and gravel deposits found at the Ashbaugh mine <br />site are tuffaceous claystone and lenticular arkosic conglomerates of the White River Formation. <br />These finer-grained claystone materials are white to pale-pink in color. These clay-rich tuffaceous <br />materials have limited utility for road construction and maintenance uses and so will be the lower <br />limit of mining at the site when encountered by the stripping activities. <br />Exhibit S - natural gas pipeline - Weld County believes the pipeline is owned by Noble Energy. <br />Noble Energy has been contacted and was unsure whether the pipe was theirs and was researching <br />4 '_t. :- -
