RULE 4 PERFORMANCE STANDARDS <br />Vegetated areas are utilized as sediment filters. Haul Road A is under constant routine maintenance to <br />avoid damage to environmental values. <br />The construction of both haul road segments A and B was completed in 1977; however, Haul Road A will <br />be widened in 2018 including and will include an upper and lower ditches for long term stability of the <br />fill materials (please see Exhibit 7 Item 15). The design for both haul roads had been prepared based on <br />the anticipated volume of traffic and the weight and speed of vehicles to be used. The Colowyo Coal <br />haulage fleet used for transport of coal from the primary crusher to the Gossard Loadout consists of <br />highway trucks, and transport of large mining equipment to and from the Collom Pit. <br />The haul roads are located on stable terrain to minimize erosion. As shown on the Existing Structures - <br />North Map (Map 21), the haul road A crosses Taylor Creek, and has been maintained according to the <br />requirements of 4.03.1(4). The grade and pitch requirements specified in 4.03.1(3), Design and <br />Construction, are met for both haul roads. <br />Colowyo will maintain haul roads A and B throughout the life of the mine with repairs including blading, <br />filling of potholes, and replacement of road surface as necessary. Likewise, watering for dust control will <br />be implemented as necessary. <br />Section 2.05.5 discusses the changes to be made to the main haul road, a portion of which will be left in <br />place after completion of mining to retain access into the area to compliment the post mining land use. <br />Rule 4 Performance Standards 4-3 Revision Date: 6/15/18 <br />Revision No.: TR -122 <br />
