The site is in final reclamation, and not active the day of the inspection. The <br />weather was clear and dry. Contact was made with Mindy Sickles and Jason Carver of Elk Ridge Mining and <br />Reclamation, however they did not accompany the inspection as they were collecting water samples at the time. <br />Five Photos accompany this report to illustrate the observed site conditions. <br /> <br />The overall footprint of the site is in excellent condition. The Operator and it’s contractor have done an exemplary <br />job at conducting the reclamation efforts. No maintenance items or possible violations were noted during this <br />inspection. <br />BACKFILL and GRADING – Rule 4.14 <br />Contemporaneous Reclamation 4.14.1; Approximate Original Contour 4.14.2; Highwall Elimination 4.14.1(2)(f); <br />Steep Slopes 4.14.2, 4.27; Handling of Acid and Toxic Materials 4.14.3; Stabilization of Rills and Gullies 4.14.6: <br /> During this inspection, the backfilled areas of Ponds 001 and 002 were observed. The Pond 002 appeared <br />stable at the time of the inspection, and no evidence of settling, slumping or erosion was noted in the area. The <br />pond area is well vegetated and in excellent condition, as is the reclaimed ditch area to the south of the pond area. <br />The stockpile footprints of both Bench 1 material and topsoil were in the same condition. The Pond 002 and <br />contributing ditch area can be seen in Photo One. The Pond 001 area has been mostly backfilled, with a small <br />stock pond left near the Southwest corner of the permitted area. The stock pond area also appeared stable and in <br />good condition. The banks are becoming more well vegetated, and the pond contained no standing water or <br />evidence of recent containment of water. The pond area can be seen in Photo Two. The remaining backfilled area <br />showed no signs of settling, slumping or erosion. <br /> <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 /> There are two small areas located between the reclaimed Pond 001 and reclaimed facilities area in which
