Waters of the State Locational Criteria
A solid waste disposal area cannot be located in an area where the Department finds that the activities will have a detrimental effect on the waters of the state based on the following criteria:
- Current and projected use of water resources in the potential zone of influence. Potential Zone of Influence is the vertical and horizontal ground water travel time based on hydrogeologic setting (time of travel during active and post-closure life of the facility).
Ground water elevation and proposed separation between the lowest point in the cell and the predicted maximum water table elevation.
- Water Well Usage:
- Public, Private, industrial, irrigation, livestock, etc.
- Well construction, yield, static water levels, etc.
- Documentation available from the Department of Natural Resources or local well driller.
- Surface Water Usage:
- Streams: perennial/intermittent
- Ponds, wetlands
Potential interrelationship of the local aquifers and surface waters based on historical records or other sources of information.
- Areas having high ground water tables may be restricted to maintaining a safe vertical distance between deposited refuse and the maximum water table elevation.
- Requires site specific information from hydrogeologic characterization
Background and initial quality of water resources in the potential zone of influence.
- Hydrogeologic characterization
- Natural Resources District (NRD) Ground water management plans
Description of soil and bedrock to a depth that will allow accurate evaluation of the water quality protection provided by the soil and bedrock.
- Basic drinking water quality parameters
- Others based on previous land use
Potential leachate generation and the potential for pollution of the waters of the State.
- Detailed description from hydrogeologic characterization.
Other Locational Criteria
- Hydrogeologic characterization
- Hydrologic Evaluation of Landfill Performance (HELP) model
- Cannot be located within 1,000 feet of an existing state, interstate, or federal highway unless screened by natural objects, plantings, fences, or other appropriate means.
- Airport Proximity
- Demonstrate that the facility does not pose a bird hazard, if the facility location is within:
- 10,000 feet of any airport runway end used by turbo aircraft; or
- 5,000 feet of any airport runway end used only by piston-type aircraft.
- If the facility is located within a 5-mile radius of any airport runway, the affected airport must be notified of the construction. Place a copy of the notification in the site operating record.

- A new municipal solid waste disposal area or a lateral or vertical expansion thereof cannot be located in a 100 year floodplain.

- A new solid waste management facility or lateral expansion cannot be located in a wetland.

Seismic Impact Zones:
- New municipal solid waste disposal areas (and lateral expansions) cannot be located within 200 feet of a fault unless it can be demonstrated that an alternative setback distance of less than 200 feet will:
- Prevent damage to the structural integrity; and
- Be protective of human health and the environment.
- SOURCE: U.S. Geological Survey 1978 publication on the location of Holocene faults in the United States.
- New municipal solid waste disposal areas (and lateral expansions) cannot be located in a seismic impact zone unless it can be demonstrated that all containment structures, liners, leachate collection systems, and surface water control systems, are designed to resist the maximum horizontal acceleration at the site.
- Seismic impact zone: An area with 10% or greater probability that the maximum horizontal acceleration of lithified earthen material expressed as a percentage of the earth’s gravitational pull (g) will exceed .10g in 250 years.
- Maximum Horizontal Acceleration: Depicted on a seismic hazard map with a 90% or greater chance the acceleration will not be exceeded in 250 years, or site-specific findings.
- SOURCE: U.S. Geological Survey Open-File Report 82-1033 titled “Probabilistic Estimates of Maximum Acceleration and Velocity in Rock in the Contiguous United States.”
Threatened and Endangered Species:
- New municipal solid waste disposal areas (and lateral expansions) located in an unstable area must demonstrate that engineering measures have been incorporated that ensure the integrity of the containment systems. The demonstration must be recorded in the operating record of the facility.
- Karst terrains
- Poor foundations-loess
- Areas susceptible to mass movement
