The weather was warm and <br />very dry. The inspector met Dr. Corley, Carin Corley, Ann Corley, Daryl Mergen (supporting the landowner, Dr. <br />Corley) , Jack Robeda (Ranch Manager), and George Patterson of Energy Fuels Coal Company, at the intersection <br />of the Thompson Ranch driveway and Newlin Creek culvert. <br />HYDROLOGIC BALANCE - Rule 4.05 <br />Drainage Control 4.05.1, 4.05.2, 4.053; Siltation Structures 4.05.5, 4.05.6; Discharge Structures 4.05.7, <br />4.05.10, Diversions 4.05.4, Effluent Limits 4.05.2, Ground Water Monitoring 4.05.13; Surface Water Monitoring <br />4.05.13; Drainage — Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />On Monday, March 19, 2012, the Division received an e -mail message from Dr. Corley, a surface landowner of <br />portions of the Southfield Mine, with concerns regarding diminution of the flow in Newlin Creek as it crosses the <br />Southfield Mine workings, and regarding inflows of groundwater in the mine void. <br />Dr. Corley also had concerns that the mine voids have filled and the mine pool has reached equilibrium. <br />The inspection initiated at the Thompson driveway culvert over Newlin Creek. The Creek was dry at this point. <br />We walked downstream several hundred feet to a point where Jack Robeda observed the surface flow of Newlin <br />Creek disappear into the alluvium in the second quarter 2011. This location was marked with pink flagging tape <br />and GPS coordinates. Dr. Corley had the coordinates in his GPS. The Division collected GPS r using an Xplore <br />Tablet. <br />This section of the Newlin creek bed is rocky and sandy with no surface expression of subsidence cracks or holes. <br />There is no apparent cracking or holes visible at the point that Mr. Robeda reported the 2011 surface flow <br />diminishing into the alluvium. <br />Number of Partial Inspection this Fiscal Year: 6 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 2 of 6 <br />
