The photos were reviewed by Janet Binns of DRMS on 1/28/2016. This report is a result of observations <br />of the aerial photos. <br />The mine is a reclaimed surface mine. As such, the site is in active, no mining personnel remain on the site, and <br />the site is snow covered. <br />FISH and WILDLIFE — Rule 4.18: <br />The mine is snow covered. Very few animal tracks were visible in the snow. There is no evidence of <br />large animals bedding down on the site. <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 />Ponds are frozen and snow covered. <br />Pond 12 appears to have some open water and flow keeping a portion near the pond inlet open. Based on the open <br />channel downstream of the discharge riser, it appears that pond 12 was discharging at the time of the photo. <br />Snow machine tracks were visible in the Pond 12 vicinity. <br />Stock tank 12A is frozen, snow covered and does not appear to be discharging. <br />Pond 13 is frozen and snow covered. No open water was noted and there is no apparent discharge from the riser. <br />Slopes to the pond appear stable at this time. <br />Number of Partial Inspection this Fiscal Year: 5 <br />Number of Complete Inspections this Fiscal Year: 2 <br />Page 2 of 4 <br />
