  1. Chapter 3 LANDFARM SITING COMPONENTS

  2. General Objective • Identify and explain the importance of soil, plant and regulatory factors as they relate to site selection

  3. Specific Objectives • Describe the regulatory siting requirements • Understand the importance for using a soil survey report and USGS topographical map as it relates to site selection • Describe how the Kentucky environmental performance standards apply to landfarm siting

  4. Site Selection Poor site selection can increase costs due to inefficiency, environmental problems and public opposition (both initially and after startup) Less suitable sites may restrict the type or form of waste, the method of application, and the timing of the application. These sites are likely to be more difficult to manage because storage or alternative disposal methods may be needed due to seasonal restrictions.

  5. Soil Suitability • deep, well-drained, and silt loam textured • black or dark brown colored surface, and reddish-brown or yellowish-brown subsoil • should not be mottled with gray to a depth of 40 inches • structure should be stable, and the soils should have a low shrink-swell potential

  6. Soil Suitability • Moderate to rapid infiltration rate • Moderately slow to moderately rapid permeability • Slopes between 0 and 3%

  7. Soil Survey • Find descriptions of soil types • Get soil texture and soil horizons • Presence of restrictive layers • Determine depth above bedrock • Soil permeability and infiltration

  8. Regulatory Site Restrictions • cannot be located within a 100-year flood plain unless the waste is to be injected or if surface applied, incorporation applies regardless of the density of vegetative cover. • must have soil that is at least 4 ft. deep over such restrictive layers as bedrock, and the seasonal high water table • The soil is not suitable if the permeability rate is less than 0.2 in. per hr. or greater than 6 in. per hr

  9. Regulatory Site Restrictions • slope can be no greater than 15% for any soil area used for land application • Buffer zones must be maintained between a land feature, object or structure and the land application area.

  10. Buffer Zones for SPECIAL WASTES

  11. Buffer Zones for SOID WASTES

  12. Procedures for Site Evaluation • During on site visit • Soil properties are determined and recorded • Identification of structures, objects, and land features • Buffer zones should be marked • Geological investigation related to groundwater

  13. EPS Issues • Floodplain location • Effects on endangered species • Surface water pollution • Groundwater contamination • Food chain crops • Disease vectors • Polychlorinated biphenyls • Public nuisance • Wetland designation • Karst terrain

  14. EPS Issues • Just because something is legal (or in compliance) does not mean that you will not be hearing from disgruntled neighbors

  15. General Objective • Identify and explain the importance of soil, plant and regulatory factors as they relate to site selection

  16. Specific Objectives • Describe the regulatory siting requirements • Understand the importance for using a soil survey report and USGS topographical map as it relates to site selection • Describe how the Kentucky environmental performance standards apply to landfarm siting
