Spinardi Associates construction of building pads for the plant and for sceening berms. Excavators will mine the materials and load onto a conveyor to transport the material to the processing plant. Other equipment used will be a water truck, grader and loader. RMC plans to operate 2 shifts with mining excavation conducted during the hours of 6 am to 5 pm. RMC will construct a paved entrance off Koster Road to the plant site. A landscaping screen will be developed within a 50-foot setback along Blewett Road and the northern portion of Koster Road to screen operations. Mining is divided into 9 phases beginning in Phase I. While mining Phase I, the Phase IV area will be temporarily bermed to create a silt pond using Phase I and Phase IV overburden. Once Phase I is mined out, it will be used for permanent silt containment and the silt temporarily contained in Phase IV will be pumped into the Phase I silt pond. Mining will continue to Phase II, III and IV and so on. Once Phase IV is mined out, the pit will be used as a permanent silt pond along with Phase I. If additional silt storage is needed during the course of mining, Phase V will be used as a silt pond. RMC's Mining and Phasing Plans are depicted in Figures 4 through 12. Temporary slopes will be mined to an effective 3/4:1 slope. Within two years after a phase has been mined out, and in accordance with the Table 1 - Reclamation Schedule, the slope will be backfilled to 2:1 using overburden and interbedded clays. The slopes will be covered with topsoil and hydroseeded for erosion protection. San Joaquin County Surface Mining Ordinance 9-1415.3k - Slopes, requires final slopes over 50 feet in vertical distance to have terraces and terrace drainage. Minimum final slopes may be 1 '/2: 1. In lieu of this requirement, we are requesting to build final slopes to a full engineered 2:1 (horizontal to vertical) using overburden and interbedded clays then track-walk topsoil on the surface. The slope would then be hydroseeded with an appropriate seed mix for erosion control at a time that would maximized vegetative growth and erosion protection. Final slopes built in this manner would provide both slope stability and erosion control. We request this modification to the existing ordinance because we have observed successful 2:1 slopes at other RMC mining sites. In San Joaquin County, at the Huck Quarry, where the depth of mining is approximately 75-feet, the slopes are reclaimed to 2:1 without the use of terraces and are performing successfully. In contrast, at RMC's Olympia Quarry located in Santa Cruz County where terrace drainage and downspouts were constructed, RMC has encountered numerous maintenance problems. Apparently the terrace drainage and downspouts have eroded and caused erosion problems. The downspouts, catch basins, terraces and energy dissapators not only look manmade, they require maintenance both during and after mining is complete to keep the pipes from becoming undermined, clogged or disconnected. The terraces have a tenancy to grow large 2
