During the <br />inspections, the Division inspector identified deficiencies associated with Wildcat Mining <br />Corporation's permitting and management of stormwater discharges from the industrial and <br />construction activities at the sites. In response to the inspections, Wildcat Mining Corporation <br />submitted correspondence to the Division requesting a brief extension of time to respond to the <br />Division's inspection findings. However, Division records establish that Wildcat Mining <br />Corporation has failed to respond to the inspection findings, including a failure to obtain coverage <br />under a Colorado Discharge Permit System ("CDPS") permit for stormwater discharges associated <br />with construction activity, and a failure to implement Best Management Practices to control <br />pollutant discharges from the industrial and construction activities at the sites. <br />The Division expects Wildcat Mining Corporation to immediately implement necessary measures to <br />obtain coverage under all applicable CDPS permits and to ensure the development and <br />implementation of functional stormwater management systems at the. sites, including, but not <br />limited to, complete and effective Stormwater Management Plans and the proper design, selection <br />and installation of Best Management Practices to control pollutant discharges from the sites. The <br />planning and implementation of the corrective actions should be coordinated with the Division of <br />Reclamation, Mining and Safety ("DRMS"). However, the Division expects Wildcat Mining <br />Corporation to take all necessary measures to secure access, temporary authorizations, and/or other <br />permissions to expedite the stormwater corrective action process at the sites. DRMS has previously <br />informed Wildcat Mining Corporation that handwork for the installation of silt fence, ditches, <br />berms, and/or other stormwater control measures could be allowed if Wildcat Mining Corporation <br />were to submit of a plan to DRMS for review and approval. As such, the Division expects Wildcat <br />Mining Corporation to expeditiously submit plans to DBMS for the permitting and installation of
