r VI, with cross section locations shown on Exhibit V. A post mining topography map is provided as Exhibit'VII and typical cross sections are shown on Exhibit.IV. 3. Describe how slopes will lie stabilized to prevent failures and.slides, earth f flows; falling rock, and ,erosion. Working slopes will:be no greater than those;.allowed,by Cal' OSHA and/or Federal MSIR regulations: Final slopes will approximate those that exist-prior to mining and-in no.case will they be greater than 2 feet.horizontal to .1 foot vertical. Typical cross sections illustrating premining, during mining and post mining slopes ate provided in Exhibit IV. Approximate post mining'topography is illustrated in Exhibit VII and in cross section in Exhibit VI. Cross section locations are shown in Exhibit V. Due to the relatively thin layers of overburden, topsoil and the aggregate reserves itself, high*all heights will be relatively small, often only about 10 feet. D. Impoundments: Describe how impoundments will.be reclaimed (e.g., rued dewatered, capped, revegetated, removed, etc. — No impoundments are planned for the Permit Area_ E. Drains e: Describe provisions for natural draina a and how erosion of disturbed land and sedimentation will be controlled during,.cxcavation and afterfinal reclamation (e.g., revegetation, rip rap, sedimentation basins, berms, ditches. water bars, silt screens regrading, etc.). —Mining activities in the proposed Permit Area have been designed to contain all runoff from disturbed areas on the site. All excavation boundaries will be sloped back into the active pit to avoid contamination of runoff entering natural drainages that exit the property. Runoff from disturbed slopes will be retained on the site. KRC has an NPDES Storm Water Discharge Permit issued by the Central Valley Regional Water Quality Control Board (CVRWQCB). The associated storm water pollution control plan includes provisions for constructing and maintaining Best Management Practices to control erosion and prevent significant quantities of sediment from leaving the site. The CVRWQCB has also adopted waste discharge requirements for the project. KRC intends to modify both the NPDES permit and waste discharge requirements, as needed, to include the new Permit Area proposed in this permit application. F. Disposition of Old Equipment: Discuss the disposition of equipment, buildings, structures, etc. — No buildings or other permanent structures are planned for the proposed Permit Area. c. Revegetation Explain topsoil (or soil substitute) redistribution methods, including volumes of materials to be redistributed, equipment and methods for transport, methods for Distribution Copy Page 12 of 14 August 2, 2006
