Non-Water Release Corrective Action Plan <br /> Corral Hollow Sanitary Landfill <br /> • above (Table B-1, Appendix B). <br /> TABLE 4 <br /> PSEUDO-STATIC SLOPE STABILITY ANALYSIS <br /> FIGURE NO. DESCRIPTION OF ANALYSIS YIELD ACCELERATION,K, <br /> B-1 Section A-A' 0.44g <br /> B-2 Section B-B' 0.448 <br /> B-3 Section C-C' 0.5g <br /> The results of the calculations indicate negligible permanent dynamic displacement of the <br /> refuse prism from the PGA based on the MCE design earthquake for the cross sections analyzed <br /> indicating that the landfill is stable. <br /> 4.1.5.4 Dynamic Landfill Final Cover System Analysis <br /> The majority of the existing landfill slopes are constructed at an inclination of 5:1 (horizontal to <br /> vertical) and have a soil cover consisting of the following (from top to bottom): <br /> • • 1-foot thick vegetative cover <br /> • 1-foot thick low permeability layer <br /> • 1-foot thick foundation layer <br /> • Refuse <br /> A different landfill cover was constructed in 2013 (Shaw, 2012) in the extreme northeastern <br /> portion of the site on either side of the roadway (covering approximately 1.6 acres). The cover <br /> consists of the following (from top to bottom): <br /> • 1-foot thick vegetative layer <br /> • 1-foot thick earth fill <br /> • 200 mil geocomposite drainage net <br /> • 60 mil double-sided textured LLDPE <br /> • 1-foot thick foundation layer <br /> The soil parameters used for the cover materials are presented in Table 2. <br /> To evaluate the majority of the existing landfill cover system, a stability analysis was performed <br /> for the landfill slopes at an inclination of 5:1 (horizontal to vertical). The analysis utilized the <br /> 10 <br /> Geo-Logic <br /> ASSOCIATES <br />
