a) Seismic
Considerations
1) Portions of new facilities
where treatment, storage or disposal of hazardous waste will be conducted must
not be located within 61 meters (200 feet) of a fault that has had displacement
in Holocene time.
2) As used in
subsection (a)(1):
A) "Fault" means a
fracture along which rocks on one side have been displaced with respect to
those on the other side.
B)
"Displacement" means the relative movement of any two sides of a fault measured
in any direction.
C) "Holocene"
means the most recent epoch of the Quaternary period, extending from the end of
the Pleistocene to the present.
BOARD NOTE: Procedures for demonstrating compliance with this
standard in Part B of the permit application are specified in 35 Ill. Adm. Code
703.182.
Facilities that are located in political jurisdictions other than those listed
in appendix VI to 40 CFR 264 (Political Jurisdictions in Which Compliance with
§ 264.18(a) Must Be Demonstrated), incorporated by reference in 35 Ill.
Adm. Code
720.111(b),
are assumed to be in compliance with this
requirement.
b) Floodplains
1) A facility located in a 100-year
floodplain must be designed, constructed, operated and maintained to prevent
washout of any hazardous waste by a 100-year flood, unless the owner or
operator can demonstrate the following to the Agency's satisfaction:
A) That procedures are in effect that will
cause the waste to be removed safely, before flood waters can reach the
facility, to a location where the wastes will not be vulnerable to flood
waters; or
B) For existing surface
impoundments, waste piles, land treatment units, landfills and miscellaneous
units, that no adverse effect on human health or the environment will result if
washout occurs, considering the following:
i)
The volume and physical and chemical characteristics of the waste in the
facility;
ii) The concentration of
hazardous constituents that would potentially affect surface waters as a result
of washout;
iii) The impact of such
concentrations on the current or potential uses of and water quality standards
established for the affected surface waters; and
iv) The impact of hazardous constituents on
the sediments of affected surface waters or the soils of the 100-year
floodplain that could result from washout;
2) As used in subsection (b)(1):
A) "100-year floodplain" means any land area
that is subject to a one percent or greater chance of flooding in any given
year from any source.
B) "Washout"
means the movement of hazardous waste from the active portion of the facility
as a result of flooding.
C)
"100-year flood" means a flood that has a one percent chance of being equalled
or exceeded in any given year.
BOARD NOTE: Requirements pertaining to other federal laws
that affect the location and permitting of facilities are found in
40 CFR
270.3. For details relative to these laws,
see USEPA's manual for SEA (special environmental area) requirements for
hazardous waste facility permits. Though USEPA is responsible for complying
with these requirements, applicants are advised to consider them in planning
the location of a facility to help prevent subsequent project delays.
Facilities may be required to obtain from the Illinois Department of
Transportation on a permit or certification that a facility is
flood-proofed.
c) Salt dome formations, salt bed formations,
underground mines and caves. The placement of any non-containerized or bulk
liquid hazardous waste in any salt dome formation, salt bed formation,
underground cave or mine is prohibited.
