PERMIT#:M1978072 <br /> INSPECTOR'S INITIALS:RAR <br /> INSPECTION DATE:22 September,2021 <br /> OBSERVATIONS <br /> This inspection was conducted by the Colorado Division of Reclamation, Mining and Safety(The Division), <br /> in response to the surety release request submitted on 4 August 2021. The site was previously inspected by <br /> the Division on 28 January 2020 during a routine inspection. Jason Eager with Lincoln County accompanied <br /> me, Robin Reilley, of the DRMS during the inspection. The weather was calm, and the sky was clear. <br /> The Brent Pit is located on the south bank of Hell Creek,north of Arriba, and accessed through a gate off of <br /> County Road 3R just east of County Road 42. The pit is a 112 operation permitted for 14.16 acres for the <br /> removal of sand and gravel for county road maintenance and repair. A mine sign was observed as required <br /> by Rule 3.1.12. <br /> As reclamation is stated to have been completed,the site was not active at the time of inspection. All <br /> material stockpiles, structures and equipment have been removed. Annual reports indicate that reclamation <br /> occurred in the 2019/2020 report cycle. The Hell Creek stream bank where piping was observed in the past <br /> has been stabilized with concrete block placed as riprap. There was evidence of rilling on portions of the <br /> north facing slope of the former highwall. The soils in the area are silty, eolian soils and prone to visible <br /> signs of wind and water erosion. Seeding took place on two occasions to mitigate a marginal response the <br /> first time. Vegetation for the most part was adequately established with diverse rangeland species. Some <br /> weeds were present,notably Xanthium strumarium (cockleburs), and did not pose a cause for concern. <br /> Overall the site appeared stable. <br /> The Division currently holds no financial warranty because it is a county operation. No problems or <br /> violations were noted during this inspection. The Division finds that the pit can be released. <br /> Responses to this inspection report should be directed to: Robin Reilley at the Division of Reclamation, <br /> Mining and Safety, 1313 Sherman St., Room 215,Denver, CO 80203.
