Current through Register Vol. 50, No. 6, June 20, 2024
A. Disposal Site Suitability for Near-Surface
				  Disposal. The primary emphasis in disposal site suitability is given to
				  isolation of wastes and to disposal site features that ensure that the
				  long-term performance objectives are met.
1.
				  The disposal site shall be capable of being characterized, modeled, analyzed
				  and monitored.
2. Within the region
				  where the facility is to be located, a disposal site should be selected so that
				  projected population growth and future developments are not likely to affect
				  the ability of the disposal facility to meet the performance objectives of this
				  Chapter.
3. Areas shall be avoided
				  having known natural resources which, if exploited, would result in failure to
				  meet the performance objectives of this Chapter.
4. The disposal site shall be generally well
				  drained and free of areas of flooding or frequent ponding. Waste disposal shall
				  not take place in a 100-year flood plain, coastal high-hazard area or wetland,
				  as defined in Executive Order 11988, "Floodplain Management
				  Guidelines."
5. Upstream drainage
				  areas shall be minimized to decrease the amount of runoff which could erode or
				  inundate waste disposal units.
6.
				  This disposal site shall provide sufficient depth to the water table that
				  ground water intrusion, perennial or otherwise, into the waste will not occur.
				  The department will consider an exception to this requirement to allow disposal
				  below the water table if it can be conclusively shown that disposal site
				  characteristics will result in molecular diffusion being the predominant means
				  of radionuclide movement and the rate of movement will result in the
				  performance objectives being met. In no case will waste disposal be permitted
				  in the zone of fluctuation of the water table.
7. The hydrogeologic unit used for disposal
				  shall not discharge ground water to the surface within the disposal
				  site.
8. Areas should be avoided
				  where tectonic processes such as faulting, folding, seismic activity, or
				  vulcanism may occur with such frequency and extent to significantly affect the
				  ability of the disposal site to meet the performance objectives of this Chapter
				  or may preclude defensible modeling and prediction of long-term
				  impacts.
9. Areas shall be avoided
				  where surface geologic processes such as mass wasting, erosion, slumping,
				  landsliding, or weathering occur with such frequency and extent to
				  significantly affect the ability of the disposal site to meet the performance
				  objectives of this Chapter, or may preclude defensible modeling and prediction
				  of long-term impacts.
10. This
				  disposal site must not be located where nearby facilities or activities could
				  adversely impact the ability of the site to meet the performance objectives of
				  this Chapter or significantly mask the environmental monitoring
				  program.
