GCC Rio Grande, [nc: Red Rock Mine <br />Drought Management Plan <br />• Field Observations of Erosion -Excessive wind and water erosion may be <br />directly observed or indirectly identified through field chazacteristics. For <br />example, wind erosion may remove and redeposit soil, create aeolian dunes, <br />abrade plants with soil particles, create plant and rock fragment pedestals, or leave <br />rock mulch through removal of finer soil particles. Water erosion may create rills <br />and gullies, transport litter materials, leave sediment deposits and create plant <br />pedestals. These conditions will be noted during routine and opportunistic <br />monitoring of reclaimed azeas. <br />When inspection or monitoring on reclaimed lands indicates that drought is adversely <br />impacting revegetation efforts, appropriate actions will be identified and corrective <br />measures implemented. As examples, inter-seeding or reseeding operations will be <br />conducted based on vegetation monitoring outcomes. When soil moisture contents are <br />substandard, seeding operations may be postponed until soil moisture conditions <br />improve. When seeding is postponed, soils within these azeas will be stabilized to protect <br />them from excessive wind or water erosion as discussed in this plan and the permit. <br />When direct or indirect observations of excessive wind or water erosion are made, <br />appropriate measures will be selected and affected azeas stabilized. <br />Measures used to ensure stability and minimize drought impacts will be implemented as <br />discussed in this plan and the permit. Such measures and practices include, but are not <br />limited to, the following: <br />• Mulching; <br />• Inter-seeding and reseeding; <br />• Cover cropping; <br />• Application of bonded ftber matrices; <br />• Application of erosion control blankets; <br />• Surface roughening; <br />Habitat Management, Inc 3 03 / 03 / 2003 <br />
