Approximately 3600 CY of soil will be excavated from the on site retention pond to be used as <br /> cover and vegetative layer. Placement of soil over the GCL will cause the relocation of the road <br /> and the drainage ditch (Figure 4). Grass seed will be raked in the vegetative layer soil on all <br /> slopes. Anti-erosion mats will also be placed on the steep slope at the edge of roadway. The final <br /> slope required for all surfaces will be 2% minimum(Figure 4). <br /> HEALTH AND SAFETY PLAN <br /> SAFETY STANDARDS <br /> CAL/OSHA safety rules and regulations we will follow fully and completely during this project. <br /> SITE CONDITIONS <br /> The work does not include excavation of refuse or contact with refuse; however,the work is in the <br /> vicinity of buried refuse and other materials. Potential hazards exist due to the presence of buried <br /> refuse, including those associated with landfill gas (LFG) and the refuse itself. Also,the work is <br /> in the vicinity of an oil pipeline, the location of which will be clearly marked prior to excavation. <br /> LANDFILL GAS <br /> When buried in a landfill, refuse and other organic material produces landfill gas (LFG). LGF is <br /> approximately 50 percent methane by volume and may contain other contaminants. Potential <br /> hazards associated with LFG are due to: <br /> 1. Oxygen deficiency <br /> 2. Combustible characteristics of LFG <br /> 3. Potential for hydrogen sulfide in LFG <br /> Potential hazards include: <br /> 1. Fire <br /> 2. Explosion <br /> 3. Asphyxiation <br /> LFG may also contain trace concentrations of organic compounds. Dilution of LFG in air to <br /> below the OSHA safety limits of 0.5 percent methane (10 percent of the Lower Explosive Limit) <br /> usually reduces the concentration of trace components to below detection limits. <br /> LFG can move through soils, especially through sandy layers that exist at the site. Movement <br /> through soils can remove the odorous compounds of LFG, such that the LFG can be detected only <br /> with the proper test equipment. <br /> Health and Safety Plan Solid Waste/Public Works <br /> Corral Hollow Sanitary Landfill Page 2 of 4 San Joaquin County October 25,2006 <br />
