Carr includes approximately 30 to 40 semi-rural residential home lots north of the site. In <br /> addition to the Connell Carr Pit north of Carr, there is another permitted aggregate mining <br /> property (M-1988-048) and railroad load-out yard approximately one mile north of the site. <br /> There are no established oil and gas wells, tank batteries, or other associated facilities located on <br /> the property. The interior of the property does not contain structures, easements, or right-of- <br /> ways not owned by the applicant or property owner. Several utility structures and associated <br /> easements and right-of-ways are located on the edges of the property or immediately adjacent to <br /> the proposed permit boundary including Nunn Telephone Company communication lines, Weld <br /> County road right-of-ways, and Poudre Valley REA power lines (see Exhibit C-1, Existing <br /> Conditions Map). None of the easements, right-of-ways, or associated structures are expected to <br /> be negatively affected by mining or reclamation operations. <br /> Nature of Deposit to be Mined <br /> The proposed permit area is located where the northern edge of the Colorado Piedmont <br /> transitions up to the High Plains of southern Wyoming. The northwestern most boundary of the <br /> historic Lone Tree Creek basin originates in the Laramie Range of the Rocky Mountains and <br /> drains southeast across the relatively flat High Plains and down through the gently rolling <br /> topography of the Colorado Piedmont. Aggregate materials within the proposed permit area are <br /> composed of Pliocene and Pleistocene terrace deposits associated with the historic Lone Tree <br /> Creek drainage system. The terrace deposits within the proposed permit area extend from the <br /> surface or near-surface to a variable depth of approximately 10 feet below the ground surface. <br /> Deposition was most likely created by streams that had been rejuvenated as a result of uplift at <br /> the close of the Tertiary period and increased water supply during the Pleistocene epoch. The <br /> under-lying Tertiary sedimentary rocks that include consolidated sand and gravel conglomerates <br /> were eroded, and the process of cutting and filling of channels was so widespread that gravel and <br /> sand were deposited in sheet-like beds. The principal streams eroded into the bedrock, cutting <br /> and building terraces along the channels. More recent streams, such as Lone Tree Creek one to <br /> two miles east of the proposed permit area, have cut through the highly erodible over-lying <br /> unconsolidated material in most areas and do not generally have associated alluvial deposition. <br /> Traditional organic topsoil on most of the site is thin or non-existent, varying from 0 to 6 inches <br /> in depth. Most of the soils are undistinguishable from the general overburden material that <br /> consists of shallow, well drained loams. Over most of the identified sand and gravel deposit is a <br /> loamy, wind-mixed veneer layer of soil/overburden material varying from 0 to near 2 feet in <br /> depth. The soil/overburden material likely developed from alluvial and eolian deposits of clay, <br /> silts, and sands. Over time, erosive forces of wind and water have influenced the soils on the site <br /> and mobile soil/overburden particles, such as silt and clay, have eroded from higher topographic <br /> positions and have been re-deposited in lower areas. The aggregate deposits and loamy <br /> soil/overburden material are underlain by a variable pattern of unconsolidated shale and <br /> sandstone parent materials. <br /> Mine Phasing <br /> Lary Two Pit <br /> DBMS 112 Permit Application Page 5 <br />
