Landfill Site Selection

Landfill Site Selection
2
Importance of Site Selection

• Minimize the future impact on public health.
• Reduction of the cost of
• Design and Construction
• Operation
• Maintenance
• Recovery of potential leachate releases.

3
Consideration Factors

• Haul Distance
• Location Restrictions
• Available Land Area
• Site Access
• Soil Conditions and Topography
• Climatologic Conditions
• Surface Water Hydrology

4
.Consideration Factors

• Geologic and Hydrologic Conditions
• Local Environment Conditions
• Ultimate Use for Completed Landfills

5
Haul Distance

• Minimize the haul distance
• Environmental and political concerns

6
Location Restrictions

• Airport Safety
• Floodplains
• Wetlands
• Fault Areas
• Seismic Impact Zones
• Unstable Areas

7
Airport Safety

• Siting limitation
• 10,000 feet turbojet aircraft airports
• 5,000 feet piston-type aircraft airports

8
Floodplains

• 100-year flood plain

9
Wetlands

• No practical alternative
• No violations of other state and local laws
• Landfill will not cause significant degradation
  of the wetland
• Minimize potential negative impacts

10
Fault Areas

• Landfills can not be sited within 200 feet of a
  fault.

11
Seismic Impact Zones
12
Unstable Areas

• Landslide prone
• Karst terrains
• Undermined areas

13
Available Land Area
For at least 5 year of operation
14
Site Access
15
Soil Conditions and Topography

• Soil Cover
• Type of operation
• Type of Equipment
• Preparation of the site

16
Climatologic Conditions
umaumauma
17
Surface Water Hydrology

• Natural drainage and runoff characteristics
• Flooding problems ,limit of 100 years flood
• Divert runoff from lakes and streams
• Measure storm runoff into landfill

18
Geologic and Hydrologic Conditions

19
Local Environment Conditions

• Recommended to built near residential and
  industrial developments
• Presently ,built in remote locations (to
  minimize impact of filling operations)

20
Ultimate Use for Completed Landfills

• A capped ,decommissioned landfill can be used for
  other purpose
• Examined for recreation sites ,sport fields
  ,parking areas
• During design ,layout and operation the end use
  should be considered
• For municipal function ,landscaping and planting
  program should be initiated.

21
Stages of a Landfill Sitting Process

• Define project and its needs
• Identify major environmental factors
• Identify candidate sites
• Collect and analyze environmental, economic, and
  socioeconomic data
• Evaluate candidates sites
• Screen candidate sites to a small number
• Collect and assess site-specific engineering and
  environmental data

22
Stages of a Landfill Sitting Process

• Recommend one or more sites for final selection
• Determine final location
