Utah Admin. Code R313-25-24 - Disposal Site Suitability Requirements for Land Disposal - Near-Surface Disposal
(1) 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.
(2) The disposal site
shall be capable of being characterized, modeled, analyzed and
monitored.
(3) 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 Rule
R313-25.
(4) Areas shall be avoided
having known natural resources which, if exploited, would result in failure to
meet the performance objectives of Rule R313-25.
(5) 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."
(6) Upstream drainage
areas shall be minimized to decrease the amount of runoff which could erode or
inundate waste disposal units.
(7)
The disposal site shall provide sufficient depth to the water table that ground
water intrusion, perennial or otherwise, into the waste will not occur. The
Director 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.
(8) The hydrogeologic unit used for disposal
shall not discharge ground water to the surface within the disposal
site.
(9) Areas shall be avoided
where tectonic processes such as faulting, folding, seismic activity,
vulcanism, or similar phenomena may occur with such frequency and extent to
significantly affect the ability of the disposal site to meet the performance
objectives of Rule R313-25 or may preclude defensible modeling and prediction
of long-term impacts.
(10) Areas
shall be avoided where surface geologic processes such as mass wasting,
erosion, slumping, landsliding, or weathering occur with sufficient such
frequency and extent to significantly affect the ability of the disposal site
to meet the performance objectives of Rule R313-25, or may preclude defensible
modeling and prediction of long-term impacts.
(11) The disposal site shall not be located
where nearby facilities or activities could adversely impact the ability of the
site to meet the performance objectives of Rule R313-25 or significantly mask
the environmental monitoring program.
