APPLICATION for DISCHARGES ASSOCIATED WITH HARDROCK MINING AND /OR MILLING 4. DESCRIBE THE INDUSTRIAL ACTIVITIES WHICH TAKE PLACE ON THIS SITE Describe the primary industrial activities which take place on site. Include the type of facility plus a brief description of the nature of the business and the industrial processes used. Include a description of the mining and milling processes where applicable. A process flow sheet would be acceptable. The Cash Mine is an inactive underground gold and silver mine. 5. IS THIS FOR AN EXPLORATORY, ACTIVE MINING /MILLING, INACTIVE MINING, OR IS THE SITE IN TEMPORARY CESSATION? Inactive Mining If Exploratory — please submit any known water quality/quantity data relative to the discharge and the receiving stream which reflects the conditions prior to the present activity, the length of time the activity is expected to be under exploration, and describe what activities will take place during exploration which could have an impact on the quality of the discharge. 6. Production: List the principal product(s) produced and maximum production rate. There is no production from the Cash Mine at this time. 7. Is this a seasonal operation ?' No ❑ Yes If yes, please indicate the months of operation: ❑ JAN ❑ FEB ❑ MAR ❑ APR ❑ MAY ❑ JUNE ❑ JULY ❑ AUG ❑ SEPT ❑ OCT ❑ NOV ❑ DEC 8. Intermittent discharges: Except for storm runoff, are any of the discharges intermittent or seasonal? . No ❑ Yes Describe the frequency, duration and flow rate of each discharge occurrence. The Cash Mine adit is now flowing at a nominal rate of less than 2 gpm. During the spring runoff, the maximum rate is about 25 gpm for several months. Activity duration: When did the mining /milling operation commence? 2008 activity from which the discharge(s) identified in item 20 originate? 1 1 years. What is the estimated life of the 9. Location map: A location map designating the facility property, intake points, discharge points, each of its hazardous waste treatment storage or disposal facilities, each well where fluids from the facility are injected underground, those wells, springs, other surface water bodies and drinking water wells listed in public records or otherwise known to the applicant and the receiving waters shall be submitted. The map shall extend one mile beyond the property boundaries. The map shall be from a 7 or 15 minute USGS quad sheet, or a map of comparable scale. A north arrow shall be shown. 10. Site Map: A map of the site shall be submitted, showing appurtenant facilities (buildings, ponds, diversion ditches, stockpiles, etc.), stream location, numbered discharge points, sampling and flow monitoring points, waste rock piles, spent ore piles, tailing dams /dikes, topsoil piles, location of french drains, mine drainage flow paths, domestic wastewater plants, power plants, truck washing areas, explosive storage areas, parking lots, vehicle maintenance areas, chemical storage areas, crusher areas and land application areas. The outfalls shall be labeled to correspond with the numbers listed in item 21. 11. Water Balance: Attach a line drawing showing all water flow through and from the mine /mill site. Indicate sources of intake water, operations contributing wastewater to the effluent, and treatment units labeled to correspond to the more detailed descriptions in item 21. Construct a water balance on the line drawing by showing average flows between intakes, operations, treatment units, and outfalls. If a water balance cannot be determined, provide a pictorial description of the nature and amount of any sources of water and any collection or treatment measures. Revised 4/2011
