March 18, 2013 <br />Mr. Dustin Czapla <br />Division of Reclamation, Mining and Safety <br />101 South 3rd Street, Suite 301 <br />Grand Junction, CO 81501 <br />INTRODUCTION <br />This Work Plan presents Wildcat Mining Corporation’s (Wildcat) approach to remove run-of-mine rock <br />that was placed within the Little Deadwood Gulch (LDG), install a culvert to convey the flows in the LDF <br />and create a bench area for egress from the Chief Portal (Phase 1). After material has been removed <br />from the LDG and the bench has been graded, Wildcat will stabilize the highwall above the Chief Portal <br />and repair the manway exit used for emergency escape from the mine and for mine ventilation. <br />Wildcat is proposing to operate the May Day Idaho Mine Complex and activated MSHA mine <br />identification (ID) number 05-03674. Wildcat will implement the corrective actions described herein <br />when all of the following conditions have been met: <br />1.Colorado Division of Reclamation, Mining and Safety (DRMS) approval of this work plan; <br />2.Approval of Wildcat’s Restoration Plan (which includes this Work Plan) from the U.S. Army Corp <br />of Engineers (USACE) and the U.S. Environmental Protection Agency (EPS); <br />3.Suitable construction weather and ground conditions. <br />Historical mining activities constructed the Chief Portal and disposed run-of-mine rock in the Little <br />Deadwood Gulch drainage channel. A portion of the drainage channel was further disturbed in 2009. In <br />early 2010, a cease and desist order to conduct any mining related activities, including operating <br />equipment without written authorization from DRMS was issued to Wildcat. Wildcat has followed the <br />cease and desist order and has been unable to complete any modifications to the LDG since that time. <br />Additionally, the U.S. Environmental Protection Agency (EPA) issued an order to Wildcat on April 9, <br />2012 for compliance for minor fills in waters of the U.S. Wildcat has prepared a separate restoration plan <br />as required by the EPA. The work in this restoration plan will be consistent with the work outlined in this <br />work plan.The EPA will be responsible for verifying compliance with Section 404 of the Clean Water <br />Act. <br />After a site investigation by DRMS, an order was issued (MV-2010-020)for constructing an illegal portal, <br />the Chief Portal, near the existing May Day 3 level.Wildcat submitted as Exhibit D, Attachment D-4 to its <br />amended Section 112d permit application the Chief Drainage Channel Reclamation Work Plan (the <br />Original Work Plan). This Original Work Plan generally addressed existing drainage conditions, <br />construction activities required to remove disposed rock from the LDG and stabilization activities after <br />construction was completed.Additional information was required at the time of approval of the Original <br />Work Plan,including a geotechnical stability analysis that demonstrates that the proposed means of <br />stabilization of the Chief Portal will have an acceptable factor of safety and the removal of all mine waste <br />Civil Engineering <br />Surveying <br />Water Resources Management <br />Water & Wastewater <br />Engineering <br />Supply Chain Logistics <br />Construction Management
