Section - 2.05.4 Reclamation Schedule -The timing of the Hubbard Creek Fansite reclamation will coincide with the schedule described above for the Upper Hubbard Creek facilities azea. Reclamation Costs - A summary of estimated costs for complete reclamation of the Hubbazd Creek Fansite azea is provided in Exhibit 2.03-E3, Insurance and Bonding Information. Coal Mine Refuse Piles -The three coal refuse disposal facilities; the East Yazd Refuse Facility, located neaz the backfilled Somerset Mine C-Seam portal; the West Valley Coal Refuse Facility, located in the first drainage west of Elk Creek; and the II West Coal Refuse Facility, located in the second significant ephemeral drainage west of Elk Creek; have been designed and constructed as permanent structures. As an integral part of pile construction, completed pile areas aze continuously or periodically reclaimed. Reclamation involves grading bench outslopes to the design configuration (< 2H:1V), grading bench surfaces to promote effective drainage, placing a minimum of 4 feet of suitable cover material, and seeding and mulching the reclaimed benches and outslopes to protect and stabilize the cover material. Because the refuse piles are designed as permanent stmccures, all associated drainage and sediment control strictures (except the sedimentation ponds associated with the West Valley and II West Coal Refuse Facilities), including undisturbed drainage diversion ditches, disturbed drainage collection ditches, and rock under-drains will be retained. Roads and Powerlines -With the exception of the following roads or road segments that will be retained to provide long-term access in conjunction with the postmining land use, existing and proposed mine roads will be removed and the associated disturbance azeas reclaimed during final grading operations: • Affected segments of Bear Creek, Lower Hubbard Creek, and Upper Hubbard Creek roads • Somerset Cemetery Road • Sanborn Creek Road • Elk Creek Road In addition to the identified major roads, there is a network of exploration, powexlitie constmction/access, and degassification well access roads within the OMI permit area. Many of these roads aze pre-law roads constructed prior to 1976 and a number of the roads are utilized to access existing public facilities (powerlines and waterlines) and adjacent private and public lands. Prior to final site redamadon, OMI will delineate and identify all existing roads and will attempt to identify any ongoing use and access requirements associated with individual roads or road segments. Any roads that were constructed subsequent to August 1977 that are no longer required for continued access will be reclaimed by blocking access with berms, rocks, or by other means, establishing passive drainage controls (water bazs and/or ditches), and ripping and seeding road surfaces. Any pre-law roads or roads required for ongoing access will be retained. For any roads retained on OMI lands to provide access to adjacent public lands, OMI will work with the land management agencies (BLM and USFS) to develop and execute any necessary easement agreements that maybe required for long-term access and maintenance.
