facilitate future maintenance. Exhibit 20-2, Post Mining Topography, shows the locations of these roads. The As- <br />built profiles and cross-sections for these roads (except Road J) are contained in Tab 13, Facilities. <br />• Road j requires the remediation of a slide on the southern portion of the road. Once the slide area is stabilized, the <br />road will be re-surveyed and an updated as-built will be submitted. <br />Road "A". <br />Rationale: This road is needed for access to the SCC owned property and shop facility and to provide the Hayden <br />Public Library access to the western portion of their property. <br />Justification: This road will provide landowner access to individual properties, including SCC owned properly and <br />the shop facility that will remain as storage for agricultural and maintenance equipment during and following final <br />bond release. Landowner request letters are contained in Appendix 20-2.1 of this attachment <br />Documentation: The road is approximately 1.5 miles (approximately 7,950 feet) in length. The road will be <br />regraded, ripped, topsoiled and seeded to create the new average 20 foot wide limited access road The originally <br />constructed road ditches and culverts will be left inplace. Exhibit 20-2, Post Mining Topography, shows the <br />location of this road. The As-built profile and cross-sections for this road will be submitted once the final regrading <br />has been completed. <br />County Road 53C (MEHR Road). <br />Rationale. This road was originally Routt County Road (RCR 53C). <br />Justification: Routt County Road and Bridge Department has requested that it be retained and regraded to meet <br />Routt County specifications. The request letter and affiliated information is included in Appendix 20-2.1 of this <br />attachment. <br />Documentation: The road is 1.62 miles (approximately 8,554 feet) in length and provides access from RCR 53 to an <br />• existing oil well. The road will be regraded to a 28 foot width with a gravel surface. The As-built profile and cross- <br />sections for this road will be submitted once the final regrading has been completed <br />Light Use Roads <br />Light use roads have been retained for limited access to the reclaimed lands to facilitate monitoring, maintenance, <br />and future landowner use. The roads are of appropriate width for the anticipated volume of traffic and the nature <br />and speed of the vehicles to be used and provide access to the interior of the mining area. In most instances, these <br />roads average 12 feet in width. In some cases these roads are extensions of roads and trails that existed prior to <br />mining. Exhibit 20-2, Post Mining Topography, shows the locations of these light use roads. <br />Light Use Road 1 (LU 1). This road is approximately 1,400 feet long and provides access to the main substation <br />from the Ridgeline Access Road The road meets the criteria for design and construction, grade, drainage, and <br />surfacing for alight use road Maintenance will be conducted as necessary until final bond release. <br />Landowner request letters are contained in Appendix 20-2.1 of this attachment. The As-built profile and cross- <br />sections for this road will be submitted once the final regrading has been completed and prior to Phase I bond <br />release request. <br />Light Use Road 2 (LU 2). This road is approximately 2,150 feet long and provides access to the shop facility area <br />and the well house. The road meets the criteria for design and construction, grade, drainage, and surfacing for a <br />light use road. Maintenance will be conducted as necessary until final bond release. <br />Landowner request letters are contained in Appendix 20-2.1 of this attachment The As-built profile and cross- <br />sections for this road will be submitted once the final regrading has been completed and prior to Phase I bond <br />. release request. <br />TR-62 20-2.2 01/09
