PERMIT #: M-2000-082 <br />INSPECTOR'S INITIALS: ECS <br />INSPECTION DATE: January 31, 2018 <br />Loloff is currently mitigating impacts to other wells surrounding the mine site by recharging groundwater from <br />the mine site into the irrigation ditch along the western boundary. The recharging effect does not appear to <br />have increased the groundwater elevations in Mr. Tyrrell's well. <br />The Loloff Mine is approved for the installation of a slurry wall to create a reservoir. The slurry wall design and <br />specifications for the site were approved by the Division on July 18, 2016. The Operator installed the slurry <br />wall around the perimeter of the site in August 2017. The Division has measured a six foot increase in water <br />elevations since the slurry wall installation in groundwater wells located northwest of the Tyrrell well. <br />The west pit of the East 8th Street site has not been dewatered for the past 2 years. The pit has been filled <br />with free river water twice in the last year, however the pit does not retain the water. The water level recedes <br />to a level approximately three feet above the pit floor. Monitoring well data provided by Superior during the <br />inspection supported the reduced groundwater levels surrounding the west pit. <br />The Division believes sufficient evidence exists to support the Tyrrell complaint that the previous dewatering <br />activity at the Loloff Mine and the lack of water in the west pit of the East 8th Street site have affected the <br />groundwater well located at 417 East 8th Street, Greeley, CO 80631. This is a problem related to Rule 3.1.6 of <br />the Mineral Rules and Regulations of the Colorado Mined Land Reclamation Board for the Extraction of <br />Construction Materials and CRS 34-32.5-116(4)(h) of the Colorado Land Reclamation Act for the Extraction of <br />Construction Materials. <br />The Division will contact the Operators of the Loloff Mine and East 8th Street site to discuss the Quality report <br />once received from Mr. Tyrrell. <br />Inspection Contact Address <br />Rick Miller <br />Superior Oilfield Services Co., LTD <br />2986 W. 29th St. #12-13 <br />Greeley, CO 80631 <br />Page 3 of <br />
