1986-1987 - Degasifzcation wells B-41 B-5, B-7, and B-8 were plugged and sealed, the <br />water tank demolished, and associated surface areas reclaimed. Borehole B-6 was <br />converted to a groundwater monitoring well and will be reclaimed when no longer <br />needed for monitoring <br />1994 -The above ground facilities, including concrete foundations, were demolished and <br />resulting demolition debris (except for the concrete rubble) removed from the site for <br />disposal. Excavated material was placed against steep slope areas. Riprap was placed in <br />the reclaimed Bear Creek channel to permanently stabilize the channel <br />1995-1996 - Concrete rubble from the 1994 demolition operations placed within the <br />limits of the fill was covered with at least two feet of non -toxic material. The area was <br />graded to final contour. The culvert in Bear Creek providing access to the former <br />escape -way was removed for off -site disposal and the affected portion of Bear Creek was <br />graded and temporarily stabilized. Graded surface disturbance areas were prepared for <br />seeding, fertilized, and seeded in accordance with the revegetation plan outlined in <br />Exhibit 2.04-E6, Vegetation Information. <br />The final topography of the Bear Creek Fansite is shown on Map 2.05-M6, Sheet 7 of 7. Specific details <br />for the reclamation of the site are given in Exhibit 2.05-E5, Item 6: <br />The reclamation activities for the Bear Creek site consist of the removal of the fans and <br />miscellaneous buildings and the eventual sealing of the ventilation shaft. The existing pad will <br />remain with an industrial post mining land use and the existing borehole and exhausters will be <br />utilized for mine methane extraction and oxidation/generation. NFELLC has obtained a COGCC <br />gas well permit for "Bear Creek Fan Borehole "for this existing borehole. See Exhibit 2.03-E4, <br />Other Permits for COGCC Borehole Bear Creek Fan Borehole. (See Drawing 2.05-M6, Sheet <br />7/7 Facilities Post Mining topography for additional details). A substation and associated power <br />line will need to remain in support of the facility. <br />The Lower Hubbard Creek facilities area was associated with the Somerset Mine, and was disturbed pre - <br />law. Specific details for the reclamation of the Lower Hubbard Creek facilities site are given on page <br />2.05-53 through -54 of the PAP: <br />The Lower Hubbard Creek facilities included the Lower Hubbard Creek portals, ventilation <br />fans, an emergency mine hoist and a coal mine development waste pile. <br />All equipment, buildings, and above ground structures have been dismantled and removed. All <br />concrete foundations have been removed, rubblized, and placed as backfill or left in place and <br />covered. All rubblized concrete fill or in place foundations have been covered with a minimum of <br />2 feet ofsuitable non-combustible and non -toxic fill material. Demolition debris remaining after <br />dismantling and removal of the surface structures and equipment did not include any non -coal <br />materials as described in Rule 4.11.4. The two Lower Hubbard Creek portals were sealed in <br />accordance with applicable provisions of Rule 4.07 (as shown by the Figure, Typical Cross - <br />Section - Mine Seals, in Exhibit 2.05-E5, Reclamation Details). Solid block or seals were <br />constructed a minimum of 25 feet in from the portal surface openings. The portal entries were <br />C-1981-022, SL-2 Page 12 of 23 <br />
