016/016A slide remediation activity. Exhibit 20 -2, Post Mining Topography, shows the locations of these roads. The As -built profiles and cross - sections for these roads are contained on Exhibit 20 -3 (sheetsl and 2).,-- Road "A ". Rationale: This road is needed for access to the SCC owned property and shop facility and to provide the Hayden Public Library access to the western portion of their property. Justification: This road will provide landowner access to individual properties, including SCC owned property and the shop facility that will remain as storage for agricultural and maintenance equipment during and following final bond release. The landowner request letter is contained in Appendix 20 -2.1 of this attachment. Documentation: The road is approximately 1.5 miles (approximately 7,950 feet) in length. The road will be regraded, ripped, topsoiled and seeded to create the new average 20 foot wide limited access road. The originally constructed road ditches and culverts will be left inplace. Exhibit 20 -2, Post Mining Topography, shows the location of this road. The As -built profiles and cross - sections for these roads are contained on Exhibit 20 -3 (sheetsl and 2). County Road 53C (MEHR Road and Oil Well Access Road). Rationale: This road combination is Routt County Road (RCR 53C) and provides access to an existing oil well.

Exhibit 20 -2, Post Mining Topography, shows the location of this road The As -built profiles and cross- sections for this road is contained on Exhibit 20 -3 (sheetsl and 2). Light Use Roads Light use roads have been retained for limited access to the reclaimed lands to facilitate monitoring, maintenance, and future landowner use. The roads are of appropriate width for the anticipated volume of traffic and the nature and speed of the vehicles to be used and provide access to the interior of the mining area. In most instances, these roads average 12 feet in width. In some cases these roads are extensions of roads and trails that existed prior to mining. Exhibit 20 -2, Post Mining Topography, shows the locations of the light use roads, while Exhibit 13 -28, As- Built Light -Use Profiles, shows the final permanent grades. Light Use Road 1 (LU -1). This road is approximately 1,450 feet long and provides access to the main substation and powerline from the Ridgeline Access Road. The road meets the criteria for design and construction, grade, drainage, and surfacing for a light use road Maintenance will be conducted as necessary until final bond release. The landowner request letter is contained in Appendix 20 -2.1 of this attachment. The As -built profile is shown on Exhibit 13 -28 and the typical cross - section is presented as Figure 13 -6, Typical Light -Use Road Section. Light Use Road lA (LU -1A). This road is approximately 490 feet long and provides landowner access from LU -1. The road meets the criteria for design and construction, grade, drainage, and surfacing for a light use road. Maintenance will be conducted as necessary until final bond release. The landowner request letter is contained in Appendix 20 -2.1 of this attachment. The As -built profile is shown on Exhibit 13 -28 and the typical cross - section is presented as Figure 13 -6, Typical Light -Use Road Section. Light Use Road 1B (LU -1B). This is a road approximately 1,600 long and is an extension of LU -1 that existed prior to power line construction and has been used by SCC /YVEA as access to the II -W shop power line.
