Environmental Protection Plan, Schwartzwalder Mine 5-1 <br />0 5. DESIGNATED CHEMICALS EVALUATION <br />This section of the EPP is not applicable to the Schwartzwalder Mine. No designated chemicals are <br />currently in use or being stored at the mine site. DRMS rules require that the EPP contain a presentation <br />and discussion of the types, quantities, and concentrations of designated chemicals within the permit area, <br />and a characterization of the designated chemicals as to: <br />Known potential to affect human health, property or the environment; <br />Expected concentrations, process solution volumes and fate of designated chemicals to be used in <br />existing and proposed extractive metallurgical processes; and <br />Material safety data sheets for designated chemicals <br />Because no designated chemicals are being stored or used at the site, no MSDSs are included with this <br />EPP. <br />Small quantities of diesel fuel (less than 250 gallons) are stored on site for equipment operation during <br />reclamation. This fuel is housed in an above-ground tank with secondary containment, consisting of a <br />lined, bermed, impoundment with adequate capacity for spill containment. <br />The remaining resin column is located in a bermed facility inside the water treatment plant. The column <br />contains Dow 21K anion exchange resin for separation of uranium from water, and will be removed when <br />the water treatment plant is dismantled. <br />U <br />r? <br />U <br />4109C.090807 Whetstone Associates
