Environmental Protection Plan, Schwartzwalder Mine 5-1 <br />• 5. DESIGNATED CHEMICALS EVALUATION <br />No designated chemicals are currently in use or being stored at the mine site. Rule 6.4.20(5) requires that <br />the EPP contain a presentation and discussion of the types, quantities, and concentrations of designated <br />chemicals within the permit area, 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 (MSDSs) 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 />Rule 8.3 requires an Emergency Response Plan for designated chemicals used on site. Because no <br />designated chemicals are currently in use at the Schwartzwalder site, no Emergency Response Plan is <br />provided in this EPP. <br /> <br />4109C.100419 Whetstone Associates
