<br />• Installation of the temporary hoist frame, hoist winches, shah sinking platform
<br />(Galloway), and support equipment
<br />• Sinking of the shah using conventional drill, blast, muck, and lining methods
<br />• Placement of shah excavation material in abandoned underground workings
<br />• Removal of the sinking plain (hoist, winches, Galloway, and support
<br />equipment) and temporary shop and water tank
<br />• Installation of a shah cover (intake shaft only) or fan, housing, and drive and
<br />control systems (fan installation) and access control fencing
<br />• Reclamation of construction staging areas
<br />Total surface disturbance associated with the proposed shale construction activities would be
<br />approximately 0.8 acres including the shaft site, construction staging area, drainage
<br />collection ditches, light-use road, and soil stockpile areas. Most of this disturbance would
<br />however, be temporary, with reclamation of all disturbance except the shafr collar, fan
<br />installation (if required) access road, and soil stockpi]e area (approximately 0.4 acres) upon
<br />completion of shaft sinking activities. It is anticipated that shafr construction would be
<br />initiated after receipt of required permit approvals in 1997 or early 1998 and would be
<br />completed in approximately four months. The following permit materials have been
<br />reviewed and revised, as appropriate, to describe design, operation, and reclamation plans
<br />and practices associated with construction of the proposed ventilation intake shafr. In
<br />addition, specific permit materials as noted with an asterisk have been updated and revised to
<br />correct previous errors or maintain organizational consistency. Please note that page 2.05-
<br />31a, as provided in this submittal, was submitted as part of both TR-28 and MR-40 which
<br />were approved on the same dace. The version provided with this submittal is the most
<br />current and accurate.
