Fremont County Department of Planning and Zoning will require a Conditional Use Permit for the mining <br /> operation. <br /> 6.4.21(4)(a and b) Other Permits and Licenses <br /> WQCD will require a storm water and process water discharge permit. <br /> APCD will require Air Pollution Emission Notices (APEN)for GMR sizing equipment,facility fugitive dust <br /> and mine fans. <br /> FCDOT's access permit will require an access with a perpendicular approach to County Road 3A. It is also <br /> likely improvements to County Road 3A will be required. <br /> 6.4.21(5) and (6) Designated Chemical Evaluation <br /> Two designated chemicals and one generic flocculant will be stored on site that aid in flotation. MSDS is <br /> provided in Appendix D. <br /> Potassium Amyl Xanthate (PAX) is a sulphide mineral collecting agent in powder form. It will be <br /> used at a rate of 0.25 lb./ton. Approximately 2,250 lbs. of PAX will be stored on site at any given <br /> time. <br /> Methyl IsoButyl Carbinol (MIBC) is a frother in liquid form. It will be used at a rate of 0.1 lb./ton. <br /> Approximately 900 lbs. of MIBC will be stored on site at any one time. <br /> A generic anionic emulsion flocculent in liquid form will be used at a rate of 0.05 lb./ton. <br /> Approximately 450 lbs. of frother will be stored on site at any one time. <br /> 6.4.21(6)(a)and (b) Designated Chemical Handling <br /> A one-month's supply of the chemicals will be stored on site in tanks at any one time.The reagents will <br /> be delivered in metal or steel drums and will be placed in a sea container designed for storage of bulk <br /> liquids. PAX is delivered in a plastic lined metal drum because it is a powder. The flocculant will be <br /> delivered in 50 lb. bags and will be stored in the sea container also. Reagent mixing will occur inside <br /> the mill building where any spillage will be contained and managed appropriately. <br /> During periods of cessation and commencement of closure, a third party chemical disposal <br /> contractor will be engaged to appropriate package, transport and dispose of any remaining <br /> reagents. <br /> 6.4.21(6)(c)Assessment of Potential Acid Mine Drainage <br /> Baseline groundwater monitoring indicates that groundwater will be encountered during ramp <br /> development. Ground water was encountered at 55 ft below ground surface on the south side of the <br /> permitted area and 175 ft. below ground surface in the vicinity of the mill building. During mine <br /> development in the unmineralized granite, in the event groundwater is encountered it will be pumped <br /> to one of the 5000-gallon groundwater storage tanks. Since the groundwater will be in the <br /> unmineralized granite, water quality is anticipated to align with baseline water quality data. The <br /> captured groundwater will be tested for quality prior to release into the natural drainage. <br /> 69 <br />
