asphalt (Permit, page 4.03-1). Haul Road B was once designated as the Access Road (Permit, page 4.03-1). This Haul Road B is an asphalt paved road from State Highway 13 to the main haul road. The old mine administrative office building is located along this Haul Road B. Both haul roads meet all design and construction requirements of the haul road regulations. The reclamation plan calls for the removal of the pavement, reduction of the road width to 12 feet, reduction of side slopes to 4:1 and revegetation of the sideslopes for Haul Road B [Permit, page 2.05-61; Rule 4.03.1(1)(f)(ii)]. Haul Road A is to be removed and reclaimed. One new haul road is proposed with Technical Revision 76 (still under consideration by the Division). This haul road will connect Haul Road A and the active mining operations in the West Pit and South Taylor Pit. This haul road will be partially in-pit and will run along the west side of the West Pit along the Taylor Draw. This haul road is proposed for removal upon completion of mining and reclamation activities. B. Access Road - Rule 4.03.2. The Sturgeon Road, from Colorado Highway 13 to the Section 21 Pond and the Section 28 Pond, is designated as an access road. This road has been designed and constructed in accordance with Rule 4.03.2. The road is surfaced with gravel and has Missouri crossings and ditches to control surface runoff. C. Light Use Roads - Rule 4.03.3. Light use roads, some of which were pre-mining trails, are used infrequently to monitor sedimentation ponds or other facilities. These roads meet the design requirements of the Rules. Some light use roads will be retained following reclamation as "ranch roads" to approximate roads that were in the area before mining (Permit, page 2.05-61). D. In-Pit Haul Roads. As presented in Rule 1.04(l 11), the definition of "road" does not include roadways within the immediate mining pit area. This includes the haul roads in the East Pit, West Pit, Section 16 Pit and South Taylor Pit. There is also a new haul road that will run from the facilities area, through the West Pit and along the Taylor Draw. The portion of the road up to the Taylor Draw is considered an in-pit road. The portion of the road in Taylor draw is not an in- pit road and, as such, must comply with Rule 4.03.1. This road will be the main haul road for the South Taylor Pit. The road is proposed for removal upon completion of mining and reclamation activities. II. Support Facilities - Rule 4.04 The Permit is found to be in compliance with the requirements of Rule 4.04. Information on mine support facilities is found in Section 4.04 of the Permit in both Volumes I and XII. The Division finds that support facilities are designed, constructed, maintained, and their planned demolition and (area) reclamation are sufficient, to prevent damage to fish, wildlife, and related environmental damages and prevent additional contributions of suspended solids to streamflow or runoff outside the permit area [Rule 4.04(1)]; control and minimize diminution or degradation of water quality and quantity [Rule 4.04(2)]; control and minimize erosion and siltation [Rule 4.04(3)]; control and minimize air pollution [Rule 4.04(4)]; prevent damage to public or private property [Rule 4.04(5)]; and minimize damage, destruction, or disruption of services provided by Proposed Decision and Findings of Compliance 14 September 2009 Permit Renewal 05 Page 34
