as a continuing record of change over time of area resources in order to assess mining induced impacts. The monitoring program shall provide the procedures and methodologies to adequately assess interrelationships between geology, topography, hydrogeology, and hydrology identified in the baseline assessment to mining activities. The monitoring program shall incorporate baseline data so as to provide a continuing record over time. Vegetation - Invasive Plant Species An inventory shall be completed for noxious weeds within the LBA tract before construction begins in order to determine whether there is a need for pre - treatments (with results of the inventory shared with the USFS and BLM weed specialist). Access and Transportation No mining related disturbance would occur within 100 feet of the outside line of the right -of -way of Stevens Gulch Road. The angle of draw used to protect the road from subsidence would be dictated by the approved Colorado DMG Mining and Reclamation Plan (the estimated angle of draw is conservatively estimated to be 25 degrees). However, mining - related disturbance may o c c u r if, after public notice and the opportunity for public hearing in the locality, a written finding is made by the Authorized Officer that the interests of the public and the landowners affected by mining within 100 feet of the public road would be protected. The lessee /operator shall be required to perform the following with respect to monitoring, repairing, and/or mitigating subsidence effects on existing facilities under Special Use Permit with the Forest Service. Monitoring, repair and/or mitigation shall be performed at the lessee's expense. • Baseline condition surveys of existing facilities shall be completed the fall following award of lease. Reports of this survey shall be deliverable to the Forest Service by December 1 of that same year. • A Surface Facility Monitoring and Mitigation Plan (Plan) shall be submitted to the Forest Service for review and approval not later than 12 months prior to scheduled undermining. The PIan shall detail measures to be taken to monitor, repair, and mitigate subsidence effects on the facilities during actual mining and for one year post mining. The lessee /operator shall schedule mining activities such that active subsidence of roads occurs during dormant winter months, unless no other practicable alternative exists. Range Management Any construction/operation impacts man-made barriers to livestock movement shall be mitigated by replacing fences, gates, cattle guards, and gates to at least the same condition as they were found before construction, and installation of new fences where needed.
