The weather was warm, and the ground was dry. The air was hazy from the Hayden <br />Pass fire in western Fremont County. The July inspection entailed the recent work performed in the Magpie <br />Diversion ditch by an EFCI contractor (and confirmation that pipes were removed from the site), the MW -NW <br />road and road spur, the reclaimed Substation #2, and the subsidence repair area from 2012. Regarding the last <br />item, Dr. Corley (landowner) has indicated that there is an additional subsidence feature near the repaired areas. <br />This has been the subject of past inspections. Dr. Corley has indicated that the feature has increased in size. <br />HYDROLOGIC BALANCE - Rule 4.05 <br />Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge Structures 4.05.7, 4.05.10; <br />Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13; <br />Drainage — Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />Where the seep structure in Magpie Diversion ditch was removed (on June 25, 2016 per Al Weaver), the channel <br />appears stable. No obvious sign of the seep was present in the ditch (no flowing water was seen). <br />GENERAL MINE PLAN COMPLIANCE: <br />EFCI has removed scrap pipe left over from removal of the seep structure. <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />No erosion problems were seen with reclamation at Substation #2 or the road to it. <br />The reclaimed MW -NW road and the reclaimed spur off of this road were inspected. There is no erosion or weed <br />patches on these roads other than cheat grass on the spur. <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: 0 <br />Page 2 of 6 <br />
