4.0 - Final Stabilization and Long-Term Stormwater Management <br />This section provides a description of the measures used to achieve final <br />stabilization and measures to control pollutants in stormwater discharges after mining <br />operations have been completed. In accordance with the guidance documentation <br />(CDHPE, 1997), " final stabilization will be reached when all soil disturbing activities at <br />the site have been completed, and uniform vegetative cover has been established with a <br />density of at least 70 percent of pre-disturbance levels or equivalent permanent, physical <br />erosion reduction methods have been employed." <br />There are no planned outfalls or culverts. The ultimate reclamation of the site is <br />for rangeland. Reclaim topography will be flat <3% sloping to the southeast. DRM&G <br />and Soil Conservation Service recommended seed mix and methods will be followed for <br />reclamation. Most final grade activities will take place as mining activities proceed. <br />Efforts will be made to achieve final grade stabilization as soon as possible after <br />excavation activities have been completed in any given area of the site.
