• <br />• <br />s <br />10. The operator/lessee of the LBA tract would be required to perform adequate baseline studies <br />to quantify existing surface and subsurface resources. Existing data can be used for baseline <br />analyses provided that the data is adequate to locate, quantify, and demonstrate interrelationships <br />between geology, topography, hydrogeology, and hydrology. Baseline studies are critical to the <br />success of future observation and assessment of mining related effects on resources in the Dry <br />Fork LBA tract. <br />11. The operator/lessee of the LBA tract would be required to establish or amend a monitoring <br />program to be used as a continuing record of change over time of area resources in order to:; <br />assessmining induced impacts. The monitoring program shall provide the procedures and-': <br />methodologies to adequately assess interrelationships between geology, topography, <br />hydrogeology, and hydrology identified in the baseline assessment to mining activities in then <br />LBA tract area. The monitoring program shall incorporate baseline data so as to provide a <br />continuing record over time. <br />12. If surface disturbance is proposed on the lease, the lesseetoperators will be required to r <br />conduct breeding bird surveys prior to surface disturbance. <br />13. If subsidence adversely affects surface resources in any way (including, but not limited to a <br />documented water loss), the Lessee, at their expense will be responsible to: restore stream <br />channels, stock ponds, protect stream flow with earthwork or temporary culverts, restore affected <br />roads, or provide other measures to repair damage or replace any surface water and/or developed <br />ground water source, stock pond, water conveyance facilities, with water from an alternate <br />source in sufficient quantity and quality to maintain existing riparian habitat, livestock and <br />wildlife use, or other land uses as authorized by 36 CFR 251. <br />14. The Lessee/Operator shall be required to perform the following with respect to monitoring, <br />repairing and/or mitigating subsidence effects on existing facilities under Special Use Permit <br />with the Forest Service. Monitoring, repair and/or mitigation will be performed at the Lessee's <br />expense. The Lessee may request variations on timing for surveys, monitoring and reporting. <br />Approving such requests would be at the discretion of the District Ranger. <br />a. Baseline condition surveys of existing facilities will be completed the Fall following <br />award of lease. Reports of this survey will be deliverable to the Forest Service by <br />December 1 of that same year. <br />b. In consultation with the Special Use Permittee and the Forest Service, install <br />equipment to monitor flow on water conveyance facilities during the Fall following <br />award of lease. now monitoring shall commence the following spring and continue until <br />one year post mining. Flow data shall be provided to the Forest Service annually by <br />December 1. <br />E <br />c. A Surface Facility Monitoring and Mitigation Plan (Plan)will be submitted to the <br />Forest Service for review and approval not later than 12 months prior to scheduled <br />undermining. The Plan will detail measures to be taken to monitor, repair and mitigate <br />subsidence effects of the facilities during actual mining and for one year post mining. <br />4
