Well Access Road. Several light use roads are also proposed for permanent <br />retention. All currently approved permanent roads are shown on Exhibit 20-2 of the <br />permit application package and have been reconfigured as Access Roads. <br />B. Access Roads <br />There are eight approved access roads in the Seneca II -W permit area; the MEHR, <br />Roads, A, G, H, J, K, Oil Well Access Road, and Ridgeline Access Road. The Oil <br />Well Access Road (approximately 0.3 miles in length) has been constructed across <br />graded spoils in the `B" Pit area, to provide access from the Mine Entrance Haul <br />Road near Pond 006 to the active oil well located adjacent to the reclaimed `B" Pit. <br />The Ridgeline Access Road extends for several miles across reclaimed land to <br />connect Haul Road "G" at the north end of the mine area to the existing road system <br />providing access to the south extension area. Both the Oil Well Access Road and <br />Ridgeline Access Road have been approved as permanent roads, and are depicted on <br />Post -mining Topography Map Exhibit 20-2. <br />2. The Division proposes to approve the retention of the access roads depicted on <br />Exhibit 20-2 since they are compatible with the approved post -mining land <br />use, and a request for their retention was submitted by the landowners <br />(4.03. 1 (1)(g)(ii)). <br />C. Light -Use Roads <br />At the Seneca II -W Mine, there are approximately 2.1 miles of existing and proposed <br />light use roads. Light -use road locations are shown on Exhibits 12-2, 12-3, and 13- <br />2, and a typical cross-section is presented on Figure 13-6. These roads are only used <br />on an intermittent basis for purposes, including but not limited to monitoring and <br />periodic maintenance of monitoring facilities and reclaimed areas. <br />II. Support Facilities - Rule 4.04 <br />Support facilities used in conjunction with the Seneca II -W Mine include an equipment <br />shop, office/bathhouse, a potable water well and supply line to the approved facilities <br />area, an electric substation, and Sediment Ponds 005, 006, 009, 015, 016, and 017. <br />Volumes 7-9, Tab 13, contain detailed information on the mine facilities. <br />III. Hydrologic Balance - Rule 4.05 <br />A. Water Quality Standards and Effluent Limitations <br />Storm runoff from all disturbed areas (except some topsoil stockpiles) and spoil <br />springs will pass through one or more sediment ponds designed to ensure that all <br />discharges meet effluent limits in SP's NPDES permit for the Seneca II -W Mine.
