ofpre-mine contours do not exist. The final reclaimed contours blend with landforms observed in the undisturbed surrounding landscape. The drainage channel ofthe unnamed drainage was reestablished through the regraded azea and riprapped with 12-inch or greater riprap on the 7.5 percent slope azeas and 6 inches or greater on the 2.5 percent grades. Some minor settling of the fill has occurred above the portal location since the initial backfilling and grading occurred, and some remedial grading has been performed to fill in settling cracks and ensure proper functioning of the sediment control system. Remaining backfilling and grading work is limited to removal of temporary drainage control structures, and provision of berm breaks along the permanent channel berms to allow reclaimed azea mnoff to enter the channel. The North Portal facilities azea was fully reclaimed in 2002, with the exception of temporary drainage control facilities, an electrical substation and power line, and portions of two topsoil stockpiles. In conjunction with future removal of the temporary upper diversion ditch and Sediment Pond 13, several approved ephemeral drainage channels will be constructed across the reclaimed surface. Between 2000 and 2003 several other disturbed azeas were fully reclaimed, including the 2 West Portals, South Fan, "B" Substation, the majorportion ofrefusearea CRDA-1, entirety of CRDA-2, the CBA-1 and RSRDA Soil Borrow Areas, and northern segment of the overland conveyor corridor. Soil Borrow Area CBA-2 was fully excavated and interim reclamation was completed. Final grading of CBA-2 will occur in conjunction with removal of Sediment Pond 11, and will entail re-alignment of the lower segment of the Coal Gulch drainage channel in the vicinity of Pond 11. Interim reclamation of the Coal Creek permanent diversion channel between the upper dip section culverts and the lazge double culverts beneath Haul Road 4 was completed in 2002; fma] reclamation of the channel segment will occur in conjunction with future removal of Sediment Ponds 6 and 10. Phase 1 bond release (SL02) was approved in August 2003 for various disturbance areas. The decision documented backfilling and grading compliance for CRDA-2 and most of CRDA-1 (excepting the temporary road left open for fitrther disposal), RSRDA slopes, Soil Bormw Area CBA- 1 and the RSRDA Soil Borrow Area, South Fan disturbances, 2 West Portal disturbances, "B" Substation Site, the North Decline, the North Portal Facilities (excepting certain remaining support facilities and future drainage channel construction), and various other miscellaneous areas. Please refer to the SL-02 findings document for additional detail. VIII. Reve eg tation Vegetation information reviewed by the Division can be found in Section 2.04.10, Tab 10, Volume 3; Revegetation Plan information is in Section 2.05.4 (2)(e), Tab14, of Volume 5 of the application. Due to the fact that the Roadside and Cameo Mines were existing prior to enactment of SMCRA and the Colorado Act, no baseline vegetation data was collected from azeas already disturbed by surface operations and facilities. The pemuttee established reference areas and gathered the appropriate baseline vegetation information prior to initial issuance of the permit. The vegetation surrounding the disturbed azea is a sparsely covered salt desert vegetation type, and along the Colorado River a riparian vegetation type exists. Common salt desert species include grasses such as galleta ilaria 'amesii ,Indian ricegrass O o sis hymenoidesl and squirreltail Sitanian h stria and shrubs such as winterfat (Ceratoides lanata , shadscale saltbush Atri lea 41
