It is specifically <br />designed to meet the applicable regulations as well as Rio Tinto internal road design guidelines while minimizing additional <br />disturbed area and preventing environmental damage. This design specifically covers those portions of the road which are <br />"Out of PiF and defined by the pit boundary shown by the legend. For those portions of the roadway within the pit area, <br />normal haul road construction practices apply. Other design requirements are shown below: <br />1. The field engineer shall have the discretion to move the road centerline horizontally a distance of up to 200 feet in any direction <br />as necessary to meet field conditions as long as the slopes and widths are maintained. <br />2. Maximum road grade is less than 10% as shown on the profile. <br />3. Cross fall slopes between centerline and road shoulders shall be between 1 and 2 percent as directed by the field engineer. <br />4. Design width shall be as shown on the cross - section. <br />5• Upon completion, the entire running surface of the road shall be surfaced with approximately 1 to 1.5 inches of rock or crushed gravel for traction. Additional <br />crushed gravel surfacing shall be reapplied as necessary throughout the life of the roadway. <br />6. A 6 foot high berm shall be used at all locations where the roadway is elevated. <br />7. Roadway signage shall be added as appropriate. <br />8_ Reflectors and Guideposts shall be installed as appropriate per Rio Tinto road standards. <br />9. Cut slopes shall be 0.5H :1 V or less when completed incompetent rock. Cut slopes in unconsolidated materials shall be laid snack at 1.5H :1 V <br />or less as directed by the field engineer. <br />10. Requirements for fill placement shall be as specifically described in Rule 4.03.1 Haul Roads (3) (e) "Road embankments ". Key elements of these requirements <br />are summarized below. <br />All vegetation material and topsoil shall be removed from the embankment foundation during construction. The existing ground shall be plowed, stepped, or <br />keyed in as required by this regulation. The material for embankments shall be reasonably free of organic material, coal, frozen materials, wet or peat material, <br />natural soils containing organic matter, or any other material considered unsuitable for use. Material containing by volume less than 25 percent of rock larger <br />than 6 inches in greatest dimension shall be spread in successive uniform layers not exceeding 12 inches in thickness before compaction. Where the material <br />for an embankment consists of large -size rock, broken stone, or fragmented material that makes placing it in 12 inch layers impossible, the embankment shall be <br />constructed in uniform layers not exceeding in thickness the approximate average size of the rock used. Each layer of the embankment shall be completed, <br />leveled, and compacted before the succeeding layer is pplaced. Embankment layers shall be compacted as necessary to ensure that the embankment Is <br />adequate to support the anticipated use. Material shall be placed in an embankment only when its moisture content Is within acceptable levels to achieve design <br />compaction. Embankment slopes shall not be steeper than 2H :1 V, except where the embankment material is a minimum 85 percent rock. In this case, slopes <br />shall not be steeper than 1.35H :1 V. <br />11, Drainage from haul road shall be directed to the pit(s) wherever possible. <br />12. A ditch shall be installed at toe of all cut slopes. <br />13. If needed, temporary erosion control measures shall be implemented during construction to minimize sedimentation and erosion until permanent control measures <br />can be established. The field engineer shall determine the need for control measures during construction. Such temporary and permanent control measures <br />would include silt fences, straw bales, straw wattles, rock check dams, or other measures such as downstream sediment ponds. <br />N :351854.94 <br />E :1328253.73 <br />N :351454,89 <br />E:1327953.80 <br />N :352245.50 <br />E :1328565.38 <br />N :352640.52 <br />E :1328871.22 <br />js <br />xoo <br />53042.78 _ <br />329168.18 <br />20 <br />xo <br />O <br />N :353385.14 <br />E :1329532.54 <br />�sX <br />N :353699.49 <br />E :1329921.02 <br />00 <br />xoo <br />N :354021.90 <br />E :1330302.93 <br />X <br />$ <br />7500 EAST HAUL ROAD PROFILE <br />,i <br />7300 <br />7200 <br />7100 <br />7000 <br />0 +00 5 +00 10 +00 15 +00 20+00 25 +00 30 +00 35 +00 40 +00 45 +00 50+0051+82 <br />7400 CENTRAL HAUL ROAD PROFILE <br />7400 <br />7300 <br />W,I,A <br />7100 <br />7000 <br />6900 <br />!100016 <br />0 +00 5 +00 10 +00 15 +00 20 +00 25 +00 30 +00 35 +00 40 +00 45 +00 50 +00 55 +00 60 +00 61 +99 <br />7500 WEST HAUL ROAD PROFILE <br />7500 <br />7400 <br />7300 <br />7200 <br />7100 <br />0 +00 5 +00 10 +00 15 +00 20 +00 25 +00 30 +00 35 +00 40 +00 45 +00 50 +00 53 +07 <br />N :354352.77 <br />E. 1330677.80 <br />�o <br />xo <br />O <br />1 <br />N:352548.28 <br />E :1330674-7511 <br />N :3 2107.98 <br />E:1830438.04 <br />N :351 48.70 <br />E:1330240.64 <br />N:354914.96 <br />E :1331257.15 <br />N :354699.49 <br />E :1331037.90 �\ <br />N :352981 <br />E :133092' <br />2oXOo <br />E :1,331203.74 <br />1 11 =400' <br />l <br />1 i <br />l <br />sc, % <br />xo�l <br />N :354 5.83 <br />E: 32060.96 <br />N :354210. <br />E :133178;
