Mine Access Road <br />The existing Mine Access Road consists of two sections; the lower section, which extends <br />from the mine entrance to where the road crossed the Starkville Gulch diversion; and the <br />upper section, from the diversion crossing to the Shop Building. The entire access road is <br />approximately IS to 20 feet wide. This road is shown in plan view on Map 12, Mine Site <br />Water Systems and Refuse Area. The existing road conforms closely to the existing <br />topography. <br />Runoff from the lower section of the access road is controlled by roadside ditches on both <br />sides of the road. The ditches are designed to collect runoff from the access road and <br />trailer pad SAE and divert it to the county frontage road drainage system. Runoff from <br />the upper section of the access road is diverted to the existing sediment pond via Yard <br />Ditch I, Culvert 3 and Refuse Collection Ditch 1. All drainage structures have been <br />designed to safely pass the runoff from a 10-year, 24-hour event. <br />The road will be used for access to the mine site during reclamation activities and routine <br />maintenance of the site. At the request of the land owner, the access road is to remain <br />after mining and reclamation is completed. <br />• Substation Light-Use Road <br />The substation light-use road provided access to the mine substation area. The road started <br />at the mine access road, near the invert of the 8' diversion culvert, and ended at the <br />substation. During backfilling and regrading, the road was eliminated. The location of the <br />substation light-use road is shown on Map l2, Mine Site Water Systems and Refuse Area. <br />Pond Light-Use Road <br />The pond light-use road is constructed between the mine access road and the sediment <br />pond embankment. The road provides access to the pond for removal of sediment and <br />routine maintenance and monitoring. The road is approximately 15 feet wide, and <br />surfaced with red-ash material. This road will remain following reclamation, to provide <br />landowner access to the pond. The location of the road is shown on Map 12, Mine Site <br />Water Systems and Refuse Area. <br />u <br />351 Revised (TR-17) January 1995 <br />
