base and 6 inches of grave] surfacing. Embankment materials utilized conformed to applicable standards. No <br />excess or unsuitable material from excavations was encountered and no acid and toxic-forming materials were <br />encountered or utilized in embankment construction. The road fill consists of mine spoils, contains less than 25 <br />S percent rock lazger than 6 inches and was spread in successive uniform layers not exceeding 12 inches, prior to <br />compaction. Fill material was not dumped in final position, but was dumped and then bladed to facilitate proper <br />compaction. Design density was achieved for each successive lift throughout the lift prior to placement and <br />compaction of the next lift. The AccessGHaulroad-was surfaced with gravel to form a durable road surface. Acid <br />and/or toxic forming substances were not used in the road surfacing. Typical gravel (road surfacing) characteristics <br />conform to the following specifications: <br />Screen Size Material Passinc <br />1-%: inch 100% <br />1 inch 75-90% <br />3/8 inch 40-75% <br />No. 4 mesh 30-60% <br />No. 10 mesh 20-45% <br />No. 40 mesh 15-30% <br />No. 200 mesh* 5-15% <br />*The fraction passing the No. 200 mesh shall not be greater than two-thirds of the fraction passing the No. 40 mesh <br />Construction activities for the access/haulroad were conducted in accordance with the approved Permit C-82-056. <br />As-built P.E. certifications for the Access/Haulroad are included in Exhibit 25, As-Built Certifications of <br />Access/Haulroad and Other Haulroads. <br />Once the road is no longer needed, culverts will be removed, and the road and associated drainage features will be <br />reclaimed by ripping, scarifying, and grading road surfaces, fills, and ditches to blend with the surrounding terrain. <br />Topsoil is generally not available for reclaiming the mine roads because they have been constructed in previously <br />disturbed azeas, therefore, the best available plant growth media will be utilized as a soil substitute. Potential <br />growth media will be analyzed for nutrients and, if indicated, soil supplements will be applied. Following soil <br />substitute replacement, reclaimed road areas will be seeded with the standard revegetation seed mix. <br />Subsequent to initial construction of the Access/IIaulroad, TCC obtained approval (MR03-184) and resurfaced the <br />existing Access/Haulroad with a 4- to 5-inch asphalt matt. The matt is approximately 30 feet wide, except adjacent <br />to the office building where it is up to 45 feet in width. Minor subgrade preparation was completed prior to <br />placement of the asphalt matt. A report addressing surfacing recommendations for the road is presented in Exhibit <br />48-3. <br />2. Haulroads <br />2A. Haulroad Conuector <br />A short (approximately 120 feet) haulroad segment was approved (Technical Revision to Permit C-82-056, April <br />16, 1984) and constructed to connect the TCC haulroad (Access/I-Iaulroad) with the existing CYCC Haulroad B. <br />This road segment extends from the Access/Haulroad at the road intersection neaz the freshwater borehole to the <br />beginning of Haulroad B-2 just west of the 0-Entry shaft and fan building, as shown on Map 24, Surface Facilities. <br />The centerline road profile for the Haulroad Connector is included as part of the Haulroad B-2 profile, and the <br />profile and typical cross-sections aze shown on Map 30, Road Profiles and Cross-Sections. <br />Road foundation and gravel thickness were designed based on site soil properties and the methods outlined in the <br />U.S. Bureau of Mines Information Circulaz, IC 8758, "Design of Surface Mine Haulage Roads - A Manual". The <br />Haulroad Connector is not within .100 feet of any public road right-of--way and will not require relocation of a <br />.public road. <br />TR06-55 2.05-67 07/26/06 <br />
