Section 780.21(b) Continued. <br />ular material developed from the mining operations. (See Exhibit <br />48, Durability Analysis of Granular Spoils for use as Haul Road <br />Surfacing.) <br />Figure 25, Existing Class I Road -Typical Sections, depicts the <br />approximate cross-section of the existing mine Haulroad A. <br />Drainage is from a center crown to roadside ditches and to cross <br />road culverts. The drainage scheme is shown more completely on <br />Map 16a, Kerr Mine Area Surface Water Hydrology. <br />For the most part, the existing Road A is located on gentle <br />slopes, but the northern 2,500 feet is located on a rather steeply <br />sloping (20-30%) sidehill where the roadway has been cut into the <br />hillside to provide stability. <br />In order to bring and keep Road A into compliance, existing <br />drainage patterns will be maintained, and as more of the existing <br />pit is backfilled, culverts will be added to handle the runoff <br />that is now intercepted by the pit. The existing grade and <br />alignment are in compliance for the weight and speed of traffic. <br />Map 30, Class I Road Profiles shows, the maximum grade on existing <br />Road A to be less than 8%. Existing Haul Road A will be restored <br />following completion of mining according to the restoration plan <br />further described in Section 816.156. <br />The tipple haul road is an existing private road constructed prior <br />to Kerr Coal's purchase of the tipple property and initiation of <br />coal haulage operations. For a number of years, Kerr Coat's use <br />of this road was governed by an easement agreement with the <br />surface ]andowners. Ownership and control of the portion of the <br />road easement owned by F. Lowell Moran was transferred to Kerr <br />Coal in 1983. Kerr still maintains the existing easement <br />agreement with the Louisiana-Pacific Lumber Company for the <br />remainder of the road. <br />osiovn ~vm <br />780-24R Revised - August 1992 <br />
