SANITARY LANDFILL OPERATIONS - Environmentally Conscious Materials Handling - page 204

c. Compute solid waste storage volume, soil requirement volumes, and
site life.
d. Develop final site plan showing normal fill areas, special working
areas, leachate controls, gas controls, surface water controls, access
roads, structures, utilities, fencing, lighting, wash racks, monitoring
wells, and landscaping.
e. Prepare elevation plans with cross-sections of excavated fill, completed
fill, and phase development of fill at interim points.
f. Prepare construction details including leachate controls, gas controls,
surface water controls, access roads, structures, and monitoring wells.
g. Prepare ultimate land-use plan.
h. Prepare cost estimate.
i. Prepare design report.
j. Prepare environmental impact assessment.
k. Submit application and obtaining required permits.
l. Prepare operator's manual.
A typical cross-section of a sanitary landfill cell is presented in Figure 7.3.
Design of a landfill should include specifics of the planning and development of
each landfill cell. The site development and design report for sanitary landfills
includes the following (O'Leary et al. 1986b):
• Site description, which includes existing site size, topography, slopes,
surface water, utilities, roads, structures, land use, soil, groundwater, explo-
ration data, bedrock and climate information
