Danny Kipp and Mark Quimby of Coors Energy <br />Company (CEC) were at the office/shop, but did not accompany Rob on the inspection. <br />The weather was clear and hot. The ground was very dry. Mark indicated, during a brief conversation at the start <br />of inspection, that the site had not seen rain for many days, perhaps weeks. <br />Danny indicated that CEC plans to perform seeding operations around the first two weeks of October 2020. He <br />also stated that the seed came from Pawnee Buttes. Seeding equipment was seen at the facilities area. <br />AVAILABILITY OF RECORDS — Rule 5.02.4(1): <br />The 2019 AHR/ARR was not seen in the office, and this needs to be remedied by CEC in the near future. It <br />should be stored with the reports from past years or placed in another obvious spot. Otherwise, the records were in <br />good shape as listed at the end of this report. <br />FISH and WILDLIFE — Rule 4.18: <br />Many birds were seen and heard at the ponds. A fox carcass was lying in the vegetation by the Dugout Pond. Four <br />antelope were seen near Parcel 23, and they ran south as the inspector approached them. <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 />Only small amounts of water (if any) were in the two ponds, and neither pond was discharging during the <br />inspection. There were no signs that they had discharged recently. As usual, they both contained large amounts of <br />riparian vegetation. No problems were observed with the two ponds except for a hole in the embankment at <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: I <br />Page 2 of 9 <br />
