4.3 Agricultural Resources r (c) Reclamation shall be deemed complete when productive capability of the affected land is equivalent to or exceeds, for two consecutive crop years, that of the premining condition or similar crop production in the area. Productivity rates, based on reference areas described in the approved reclamation plan, shall be specified in the ` approved reclamation plan. (d) Use of fertilizers or other soil amendments shall not cause contamination of surface or ground water. r In addition, Section 3711 Performance Standards for Topsoil Salvage,Maintenance, and Redistribution will apply to this project. This section requires the following: r (a) All salvageable topsoil suitable for revegetation shall be removed as a separate layer from areas to be disturbed by mining operations. Topsoil and vegetation removal shall not precede surface mining activities by more than one year,unless a longer time period is approved by the lead agency. (b) Topsoil resources shall be mapped prior to stripping and the location of topsoil ` stockpiles shall be shown on a map in the reclamation plan. If the amount of topsoil needed to cover all surfaces to be revegetated is not available on site, other suitable material capable of sustaining vegetation(such as subsoil) shall be removed as a r separate layer for use as a suitable growth media. Topsoil and suitable growth media shall be maintained in separate stockpiles. Test plots may be required to determine the suitability of growth media for revegetation purposes. r (c) Soil salvage operations and phases of reclamation shall be carried out in accordance with a schedule that: (1) is set forth in the approved reclamation plan; (2) minimizes the area disturbed; and(3)is designed to achieve maximum revegetation success r allowable under the mining plan. (d) Topsoil and suitable growth media shall be used to phase reclamation as soon as can ` he accommodated by the mining schedule presented in the approved reclamation plan following the mining of an area. Topsoil and suitable growth media that cannot be utilized immediately for reclamation shall be stockpiled in an area where it will not be disturbed until needed for reclamation. Topsoil and suitable growth media ` stockpiles shall be clearly identified to distinguish them from mine waste dumps. Topsoil and suitable growth media stockpiles shall be planted with a vegetative cover or shall be protected by other equally effective measures to prevent water and wind r erosion and to discourage weeds. Relocation of topsoil or suitable growth media stockpiles for purposes other than reclamation shall require prior written approval from the lead agency. (e) Topsoil and suitable growth media shall be redistributed in a manner that results in a stable,uniform thickness consistent with the approved end use, site configuration, and drainage patterns. r California Farmland Mapping and Monitoring Program r The California Department of Conservation, under the Division of Land Resource Protection, has set up the FMMP which monitors the conversion of the state's farmland to and from agricultural use. The map series identifies eight classifications and uses a minimum mapping unit size of 10 acres. The FMMP also produces a biannual report on the amount of land converted from ` RMC Pacific Vemalis Quarry Mining and Reclamation Project .3-7 ESA/203015 Draft Environmental Impact Report May 2006 r
