2.the name of any computer program used to determine the factors of safety; and <br /> 3. a description of the various assumptions used in the stability analyses(height of fill,slope and bench <br /> configuration,etc.). <br /> (B) The stability analysis shall address all portions of the Unit and its immediate surroundings that are located <br /> in areas subject to liquefaction or unstable areas with poor foundation conditions, as identified either in the ROWD <br /> or in the Seismic Safety Element of the County General Plan,and shall address all portions of the Unit that <br /> incorporate geomembranes as part of the Unit foundation or containment system(including the final cover). <br /> (C) The stability analysis shall be prepared by a registered civil engineer or certified engineering geologist. <br /> Except as otherwise provided in&(f)(5)(D),the report must indicate a factor of safety for the critical slope of at least <br /> 1.5 under dynamic conditions.Regardless of the analysis method used,the stability analysis report shall include at <br /> least the following elements: <br /> 1. report preparation shall be in accordance with CDMG Note Number 42,"Guidelines for Geologic/Seismic <br /> Reports,"May 1986,and CDMG Note Number 44,"Guidelines for Preparing Engineering Geologic Reports,"April <br /> 1986,[both available from the California Division of Mines and Geology(CDMG), 801 K Street, MS14-34, <br /> Sacramento, CA 95814-3532,phone 916-445-5716] which are both incorporated by reference, and shall include the <br /> following seismicity elements: <br /> a. a review of earthquakes during historic times; <br /> b. location of active major faults; and <br /> c. surface investigation of the site and surrounding area; <br /> 2. the location of the critical slope and other slopes analyzed to determine the critical slope shall be shown in <br /> map view; <br /> 3. calculations used to determine the critical slope; <br /> 4. a profile of the critical slope geometry showing the various layers including the proposed fill surface,final <br /> cover,mitigation berms, lifts or cells of waste,fluid levels, or any feature that may serve to reduce the stability of the <br /> slope or may represent a potential failure surface; and the proposed ground surface, soil or rock layers and structural <br /> features; <br /> 5. the engineering properties of the refuse and other layers making up the site,shall be analyzed when <br /> determining the critical slope.These properties shall include a site specific assessment of the strength parameters,the <br /> unit weight and, if using&(f)(5)(D),the shear wave velocity of each of these layers; <br /> 6. an assessment of the engineering properties of the underlying foundation materials under both static and <br /> dynamic conditions based on field and laboratory tests as determined necessary by a registered civil engineer or <br /> certified engineering geologist; <br /> 7. the maximum expected horizontal acceleration in rock at the site determined for the design earthquake for <br /> the Unit under 420370[i.e., for Class II Units,the maximum credible earthquake(MCE),and for Class III Units,at <br /> least the maximum probable earthquake(MPE)],as supported by data and analysis.For Class III landfills,the <br /> maximum expected acceleration in rock from the MCE can be used instead of the MPE; <br /> 8. seismic shaking parameters other than acceleration shall also be included in any assessment of dynamic <br /> slope stability.These parameters shall include at least earthquake magnitude and duration; <br /> 9. documentation of any peer reviewed reduction factor for acceleration applied to attenuate the acceleration <br /> through the soil column or fill materials;and <br /> 10. documentation, as part of the dynamic stability determination,of any peer reviewed amplification factor <br /> used for acceleration in loose saturated soils, if the Unit is located in an area subject to liquefaction,poor foundation <br /> conditions,or seismic amplification. <br /> (D) In lieu of achieving a factor of safety of 1.5 under dynamic conditions,pursuant to&(f)(5)(C), the <br /> discharger can utilize a more rigorous analytical method that provides a quantified estimate of the magnitude of <br /> movement. In this case,the report shall demonstrate that this amount of movement can be accommodated without <br />
