<br />19RT Mine Dewatering Borehole and Pipeline - Given the proximity of existing ranch roads, 1 C does not plan u,
<br />anticipate the need for nevi road CvuatiUCtiou To aCee33 the 19RT Dccwate,ung Borehole drill-site. With dry ground

<br />In all Upland areas. For boil, the 31,aft pad; and along the 6,200-toot pipeline corridor. construction will involve
<br />removal of any large vegetation and stripping and stockpiling of other vegetation, soil, and organic materials.
<br />Given an average soil depth of approximately 6 inches ill the upland a,ca37 a pad a,ca of app,oAin,nately 0.35 arcc3,
