EXHIBIT G Water Information (1) If the operation is not expected to directly affect surface or groundwater systems, a statement of that expectation shall be submitted. This operation is not expected to directly affect groundwater systems in the area of the mining site. A surface water drainage course directly west of the mining area has been diverted to the north of the mining area into storm water detention pond area. Please refer to the Storm water Management Plan Map included with this Exhibit as well as the watershed study attached. (2) If the operation is expected to directly affect surface or groundwater systems, the Operator /Applicant shall: (a) Locate on the map (in Exhibit C) tributary water courses, wells, springs, stock water ponds, reservoirs, and ditches on the affected land and on adjacent lands where such structures may be affected by the proposed mining operations; Reference Storm Water Management Plan Map 1:400 scale for the following information: The primary ephemeral water course entering permitted land at the southwest comer of the property is diverted north as shown on the map as that drainage entering Sediment Pond #1. There are no other wells, springs, stock water ponds, reservoirs, or ditches on the affected and or on adjacent lands where such structures may be affected by the proposed mining permit amendment. (b) Identify all known aquifers; and There are no known aquifers in the site or neighboring the site which will be affected. (c) Submit a brief statement or plan showing how water from de- watering operations or from runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater (and, where applicable, control pollution in a manner that is consistent with water quality discharge permits), both during and after the operation. The pit floor area is a contained site with all water runoff, including process water, diverted to detention ponds located north and east of the pit area. Fine granite- derived sediment, the primary potential pollutant produced within the footprint of mining and stockpiling operations, will be collected and retained within the storm water detention pond structures. (3) The Operator /Applicant shall provide an estimate of the project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. The mine operator purchases water from the City of Canon City for purposes of dust control at the site. Approximately 10,000 gallons per day is used for watering haul roads, stockpiles and wetting transfer points within the crushing and screening circuits. The reclamation plan calls for seeding of all plant species in a dry land mode with no watering of reclamation areas. (4) The Operator /Applicant shall indicate the projected amount from each of the sources of water to supply the project water requirements for the mining operation and reclamation. It is assumed that 95% or more of water used at the site will be purchased from the City of Canon City.
