<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 resoumes 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 />i2n b r,
<br />program to be used as a continuing record of change over time of area resources in order to.:
<br />asse-ssmining induced impacts. The monitoring program shall provide the procedures and`•
<br />methodologies to adequately assess interrelationships between geology, topography, y
<br />hydrojeology, and hydrology identified in the baseline assessment to mining activities in the-
<br />IBA 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 lesseeloperators will be required to
<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 culvdrts, 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 authoriaed,b- 36 C-FR-251.
<br />14. The Lessee/Operator shall be required to perform the following with respect to monitoring,
<br />repairing andlor mitigating subsidence effects on existing facilities under Special Use Pen-nit
<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. Flow 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 />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 host mining.
