October Ore Pile Reclamation Rule 8: ERP <br />110(d) Limited Impact Permit Application <br />Nuvemco LLC October Ore Pile Reclamation <br />The drainage ditch adjacent, to the existing mining road will prevent any uphill run-on of <br />precipitation to the ore pile site. At the end of each day of loading, the loader operator <br />will construct a berm from the underlying onsite soil and rock to protect the exposed face <br />and edge to prevent any precipitation from washing freshly exposed ore from the site. <br />There will be no mining operations at the site. Therefore, capture and/or retention of <br />surface water run-off from areas affected by mining operations will not be needed. <br />6.4.20 (10) (b) Because the October Ore Pile occupies less than one acre and involves <br />no new construction, the Colorado Water Quality Control Division will not require a storm <br />water management plan or permit. <br />6.4.20 (11) Surface Water Quality Data <br />6.4.20 (11) (a) The receiving stream for runoff from the October Ore Pile site is Cave <br />Canyon, an ephemeral stream which flows only in response to spring runoff and large <br />storm events. Water use classifications for Cave Canyon, as designated by the <br />Colorado Water Quality Control Commission are Aquatic Life Warm 2, Recreation E, and <br />Agriculture. Cave Canyon joins the lower Dolores River approximately 2 miles <br />downstream of the ore pile site. Water use classifications for the lower Dolores are <br />Aquatic Life Warm 1, Recreation E, and Agriculture. <br />6.4.20 (11) (b) Baseline water quality and flow data have not been collected for the <br />receiving ephemeral stream, Cave Canyon. <br />6.4.20 (12) Water Quality Monitoring Plan <br />A water quality monitoring plan has not been proposed for removal of the October Ore <br />Pile. Removal operations are not expected to have any effects on surface or <br />groundwater. <br />6.4.20 (13) Climate <br />Climate data is not being provided because no liquid containment systems for chemicals <br />or acid mine drainage will be needed in association with removal of the October Ore <br />Pile. <br />6.4.20 (14) Geochemical Data and Analysis <br />Geochemical evaluations are not proposed <br />pile has been in place for about 25 year; <br />potential for future acid mine drainage. <br />for the existing October Ore Pile.
