S~iar - 2.05.4 pr«eed in other areas, therefore, the following sections provide specific reclamation details for each • major surface disturbance area az identified and described in Settion 2.05.3, Mme Facilities. Somerset Mine and Related Facilities -The Somerset More and related facili[ies included the Somerset Mme B and C Seam portals, azs«iated surface suppott and coal handling facilities in the Elk Creek Facilities Area, and satellite support facilities in the Upper and Lower Hubbard Creek and Bear Creek areas. Demolition and Final Grading -The Somerset Mute B and C Seam portals were sealed in 1986 in accordance with 30 CFR 75.1711-2 (az shown by the figure, Typical Goss-Section Mtne Seals in Exhibit 2.05-E5, Reclamation Details). Solid 61«k Beak were constructed a minimum of 25 feet in from the portal surface openings. The portal entries were then backfilled from the seals to the portal openings with soil and broken rock materials and portal and face-up areaz were backfilled and graded to completely cover all portal structures, establish a stable slope configuration, and eliminate exposed highwall areas. The surface support and coal handling systems and facilities ass«iated with the Somerset Mme were located in either the Elk Geek Facilities Area or in the Hubbard and Bear Creek disturbance areas. The support and coal handling facilities in the Elk Geek Facihties Area have been continuously modified and upgraded to support ongoing mining and related operations for the existing Sanborn Geek and proposed future Elk Geek Mutes. Reclamation of these facilities is addressed separately under the category of Elk Creek Coal Handling, Support, and Ancillary Facihties. Similarly because they are l«ated in non-contiguous areaz, reclamation of the Bear Geek and Upper and Lower Hubbard Geek facilities and ass«iated disturbance are addressed separately under corresponding sub-headings. • Soil Replacement, Revegetation, and Reclamation Gosu -The Somerset B and C Seam portals are inunediately adjacent to the Elk Geek Facihties Area. The regraded B Seam portal area falls within the Elk Geek coal st«kpile area and soil replacement and revegetation of this area has been deferred until the coal st«kpile area u reclaimed. Similarly, the backfilled C Seam portal area has been utilized az the East Yard coal mine wazte pile and this area will be resoiled and revegetated once coal mine wazte placement activities are completed. Both areas will be reclaimed in conjunction with the Elk Creek Coal Handling, Support, and Ancillary Facilities, az described under that sub-heading. Reclamation cosu for the Somerset B and C Seam portal areas are included in the overall reclamation costs for the Ells Geek Facilities Area. Reclamation Schedule -The following s~~R,.,,~r;~rs the timing of reclamation activities that have or will «cur for the Somerset Mtne and related facilities: 1986 - B and C Seam portals sealed. Future -Ass«ia[ed surface facilities have either ah-eadybeen reclaimed (Bear and Hubbard Creek facilities) or will be reclaimed in the future in conjunction with other surface facilities areaz (Elk Geek Coal Handling, Support, and Ancillary facilities). Bear Creek Area (Somerset Mine) -The Bear Geek facilities included portals, ventilation fans, a water tank, and several degazsification brorhek. Demolition and Final Grading -All equipment, buildings, and above ground structures have been dismanded and removed. All concrete foundations have been removed, mbblized, and placed az backfill or left in-place and covered. All rubblized concrete fill or in-place foundations have been • covered with a minimum of 2 feet of suitable, non-combustible, and non-toxic fill material Demolition debris remaining after dismantling and removal of the surface structures and equipment and foundation demolition did not include any non-coal materials az defined by Rule 4.11.4.
