I. INTRODUCTION <br />The Ohio Creek No. 2 Mine was an underground mine most recently permitted and operated by <br />Robert Weaver. The ownership of the surface land for which TOJ will occur is private. The coal <br />ownership was federal (US BLM). Final inspection of reclamation adequacy for which TOJ will <br />occur was conducted July 11 - 13, 2016. <br />The site is situated in the Ohio Creek Mining District, as shown below, located at the very southeast <br />extremity of the Piceance Creek Basin, the Colorado portion of the Uinta Basin straddling the <br />Colorado -Utah state line. This mining district lies within a horseshoe -shaped outcrop of the <br />metamorphic and intrusive igneous rocks of the Sawatch uplift. This horseshoe opens up towards the <br />northwest and the deeper part of the Uinta Basin. <br />Uinta <br />Basin <br />.x <br />or j IQs rCOLORA <br />SM AM t <br />Illustration 1: Map of the Piceance Basin <br />Credit. Black Hills Exploration and Production <br />The Ohio Creek Mining District comprises three more or less persistent coal beds and numerous <br />stratigraphic horizons in the Mesaverde Formation of the mining district where thin, and local, coal <br />seams have been mapped or reported. The regional dip is approximately 3 degrees Northwest. <br />A Seam (Coal Bed #1): Located west of Carbon Creek, this bed was positioned directly over a few <br />feet of shale from the basal Mesaverde sandstone. The bed thickens west and southwest of Ohio <br />Creek, but thins eastward. This bed ranges from 0 to perhaps as much as 3.5 feet thick in the vicinity <br />of the Ohio Creek No. 2 Mine. <br />OHIO CREEK 'I'1�RMINATION OF.IURISDICTION DEC 2016 <br />AUTHOR: R. REILLEN <br />
