b <br />P <br />~ t' ii <br />~i <br />i~ <br />Energy Fuels and DMG are currently discussing the request for bond release, including <br />requirements for post-mining drainage control. Energy Fuels will amend this plan wncerning post-mining <br />stormwater control pending approval from DMG: I <br />i' <br />c. Preventive Maintenance ~ <br />Maintenance of stormwater devices for the facility involves controlling erosion and providing <br />adequate storm event capacity in the sumps and containment ditch. Energy Fuels schedules drainage control <br />maintenance work on a monthly basis. Erosion protection is accomplished by maintaining vegetative cover <br />_. and periodic grading of surface areas. Sediment sumps are cleaned-out as dictated by the frequency of <br />precipitation events. I <br />I I . <br />d. Housekeepine <br />Housekeeping procedures are accomplished during the maintenance schedule described above, or <br />more frequently if necessary. Given that the operation is in permanent cessation, and the fact that materials <br />and trash are seldom used or generated at the facility, housekeeping is generally limited to maintaiiung <br />drainage and sediment control structures. i <br />li <br />7. Comprehensive Inspection '. <br />i~ <br />• <br />All areas identified by the SWMP will be inspected quarterly by Energy Fuels personnel referenced <br />above or other qualified individual under their direction. If said inspections detect deficiencies in stormwater <br />+ control devices, or shows the plan to be inappropriate or ineffective in any area, remedial actions willbe <br />identified and implemented. Documentation of inspections, and any remedial actions, will be maintained and <br />made available for inspection at the mine office. I <br />An annual report will be submitted which documents the field inspections and summarizes I y <br />remedial work completed or planned. i, <br />A, Rewrdkcepine and Internal Reportine Procedures <br />Quarterly inspection r~rts will be reviewed by SWMP administrators and filed with the SWMP <br />and available for review by inspectors at Ute mine office. Any documentation of remedial work or identified <br />[`Ian deficiencies will be kept in the SWMP file. i <br />' I <br />! <br />9. Consistency with Other Plans <br />' Designs for drainage and sediment control structures addressed in this plan have been reviewed• and <br />.approved by the DMG and made part of permit application. j <br />~~~ <br />~ <br />i~ <br />'~~ <br />~} <br />J: ~!i <br />~ <br />r <br />,~ <br />l ~ t~~ <br />rs <br />~' <br />~ 'F <br />< <br />C <br />.; ~*~ ~.iG , <br />+K ~s <br />~ <br />~ ~~ { <br />+t4~~a4 ~ <br />v ~7T `., FyE ~ N <br />p~ ..' ~, <br />1 i ~ ~ ~~ t I ; <br />ra i>4 ~ ~.. <br />. <br />~9e 4h ~ ri ~ <br />ry5 }.~.1.
