I, Jared Ebert of the Colorado Division of Reclamation, Mining and Safety conducted the inspection. <br />Mr. Danny Kipp with Coors Energy Company accompanied me during the inspection. The weather was clear and <br />sunny. <br />AVAILABILITY OF RECORDS — Rule 5.02.4(1): <br />The records were checked at the mine office.
