EPP on- Site Review <br />At the main portal and mine support area: <br />OBSERVATIONS <br />PERMIT #: M- 2007 -044 <br />INSPECTOR'S INITIALS: GRM <br />INSPECTION DATE: October 7, 2011 <br />This inspection was conducted as part of the normal monitoring program of the Colorado Division of Reclamation, <br />Mining, and Safety (Division) for permitted sites. The Whirlwind Mine is 112d -1 uranium mine located in Lumsden <br />Canyon west of Gateway, Colorado. The Whirlwind Mine has an approved environmental protection plan (epp) on file. <br />The underground workings were not inspected due to the lack of any recent activity which created issues for potential <br />air quality and other safety issues. The Division inspector, Russ Means, was accompanied Energy Fuels representative <br />Jess Fulbright. The BLM was represented by Scott Gerwe. <br />The mine identification sign and affected area boundary markers are in place and in compliance with Rule 3.1.12. The <br />sign is located on the gate at the entrance to the site as it enters the lower bench permit access point. Permit <br />boundaries are marked by t- posts, fencing, and other geographical features that clearly marked the affected areas. <br />The inspector looked at the on -site storm -water control measures. These controls are part of the internal mine plans <br />approved by the Division and do not necessarily reflect other measures required by the Colorado Department of Public <br />Health and Environment's (CDPHE) issued stormwater permit. Those requirements are regulated by CDPHE. <br />The required stormwater run -on diversion ditches are in place as required. Ditches are clean and maintained. Some <br />native vegetation is well established which will augment water energy dissipation and slope stabilization. No erosion or <br />sedimentation issues were observed. <br />Internal stormwater controls include grading and collection ditches that currently channel water to a primary catchment <br />basin. The banks of the basin are becoming vegetated with volunteer vegetation that is being augmented by some <br />seeding from the operator. Road ditch work along the county road done by the operator is helping control stormwater <br />impacts both to the road and site. <br />The ore storage pad area has not been utilized yet. No uranium ore was noted as being mined during the last active <br />period. The mine is in stand -by mode so new waste rock has been developed or added to the dumps. <br />Groundwater monitoring has concluded the five quarters of monitoring as required. Yearly sampling is still being <br />conducted for the life of the mine and reported. The operator notes that the underground dewatering has been <br />suspended. Current water levels are below still well below pre- mining levels. The water treatment tanks are dry. <br />Sediments are noted in the bottom of the tanks that are still very wet. <br />At the Packrat Portal Area: <br />No work was initiated at the site during the last active period. The portal and shop area were uncovered under the <br />prospecting notice. The EPP for this area includes continued groundwater monitoring and surface stormwater controls. <br />The controls focus on preventing stormwater run -on from the access road to the support /staging area and <br />sedimentation control within that area. <br />The main access road has two culverts that direct water to the southern road edge and into the main drainage. There <br />are several spots where riling and minor gulling where observed. The operator, inspector, and BLM rep discussed the <br />placement of water bars in the road to reduce water energy and control surface flows better. Both agencies agreed to <br />leave the exact number of water bars up to the operator's discretion. <br />Page 2 of 4 <br />
