(h) Unstable areas.
(1) For purposes of this subsection, the
following definitions shall apply:
(A) "Areas
susceptible to mass movement" means those areas of influence, including areas
characterized as having active, or a substantial possibility of, mass movement,
where the movement of earth material at, beneath, or adjacent to the C&D
landfill, because of natural or human-induced events, results in the downslope
transport of soil and rock material by means of gravitational influence. Mass
movement shall include the following:
(iii) debris slides and flows;
(B) "Karst terrain" means an area where karst
topography, with its characteristic surface and subterranean features, is
developed as the result of dissolution of limestone, dolomite, or other soluble
rock. The physiographic features characteristic of karst terrains may include
the following:
(C) "Poor foundation areas" means those areas
where features exist that indicate that a natural or human-induced event could
result in inadequate foundation support for the structural components of a
C&D landfill.
(D) "Structural
components" means liners, leachate collection systems, final covers, run-on
systems, runoff systems, and any other component used in the construction and
operation of the C&D landfill that is necessary for protection of public
health, safety, and the environment.
(E) "Unstable area" means a location that is
susceptible to natural or human-induced events or forces capable of impairing
the integrity of some or all of the C&D landfill structural components used
to prevent releases from a landfill. This term shall include poor foundation
areas, areas susceptible to mass movements, and karst terrains.
(2) As part of the application,
the applicant for each C&D landfill shall submit an assessment of the
stability of the area and shall consider the following factors when determining
whether or not an area is unstable:
(A)
On-site or local conditions that could result in significant differential
settling;
(B) on-site or local
geologic or geomorphologic features; and
(C) on-site or local human-made features or
events, both surface and subsurface.
(3) As part of the application, the applicant
for each C&D landfill proposed to be located in an unstable area shall
provide information verifying that engineering measures have been incorporated
into the C&D landfill's design to ensure that the integrity of the
structural components of the C&D landfill will not be compromised.
(4) As part of the application,
the applicant shall submit an approval or exemption for the siting of the new
C&D unit with respect to stability from the Kansas geological survey.
