Current through Supplement No. 394, October, 2024
In addition to the general location standards in section
33.1-20-04.1-01, the following must be met:
1. Placement above the uppermost aquifer. New
CCR landfills, existing and new CCR surface impoundments, and all lateral
expansions of CCR units must be constructed with a base that is a minimum of
five feet [1.52 meters] above the upper limit of the uppermost aquifer or
demonstrate that there will not be an intermittent, recurring, or sustained
hydraulic connection between any portion of the base of the landfill and the
uppermost aquifer due to normal fluctuations in ground water elevations,
including the seasonal high water table.
a.
For a new CCR landfill or surface impoundment or any lateral expansion of a CCR
unit, the demonstration that the unit meets the minimum requirements for
placement above the uppermost aquifer must be included with the application for
a new permit or permit modification. For an existing CCR surface impoundment,
the demonstration must be included with the application for a permit
modification that meets the requirements of this chapter within twenty-four
months of July 1, 2020, as required by subsection 9 of section
33.1-20-08-02.
b. The demonstration
is considered complete when the demonstration is approved by the department and
placed in the facility's operating record.
c. An owner or operator of an existing CCR
surface impoundment who fails to make the demonstration shall begin closure as
required by subparagraph a of paragraph 1 of subdivision b of subsection 2 of
section 33.1-20-08-07.
d. An owner
or operator of a new CCR landfill, new CCR surface impoundment, or any lateral
expansion of a CCR unit who fails to make the demonstration is prohibited from
placing CCR in the CCR unit.
2. Wetlands.
a. New CCR landfills, existing and new CCR
surface impoundments, and all lateral expansions of CCR units must not be
located in wetlands unless the owner or operator demonstrates no later than the
date specified in subdivision b that the CCR unit meets the following
requirements:
(1) Where applicable under
section 404 of the Clean Water Act or applicable state wetlands laws, a clear
and objective rebuttal of the presumption that an alternative to the CCR unit
is reasonably available that does not involve wetlands.
(2) The construction and operation of the CCR
unit will not cause or contribute to any of the following:
(a) A violation of any applicable state or
federal water quality standard;
(b)
A violation of any applicable toxic effluent standard or prohibition under
section 307 of the Clean Water Act; or
(c) Jeopardize the continued existence of
endangered or threatened species or result in the destruction or adverse
modification of a critical habitat, protected under the Endangered Species Act
of 1973.
(3) The CCR
unit will not cause or contribute to a significant degradation of wetlands by
addressing all of the following factors:
(a)
Erosion, stability, and migration potential of native wetland soils, muds, and
deposits used to support the CCR unit;
(b) Erosion, stability, and migration
potential of dredged and fill materials used to support the CCR unit;
(c) The volume and chemical nature of the
CCR;
(d) Impacts on fish, wildlife,
and other aquatic resources and their habitat from release of CCR;
(e) The potential effects of catastrophic
release of CCR to the wetland and the resulting impacts on the environment;
and
(f) Any additional factors, as
necessary, to demonstrate that ecological resources in the wetland are
sufficiently protected.
(4) To the extent required under section 404
of the Clean Water Act or applicable state wetlands laws, steps have been taken
to attempt to achieve no net loss of wetlands, as defined by acreage and
function, by first avoiding impacts to wetlands to the maximum extent
reasonable as required by paragraphs 1 through 3 of subdivision a of subsection
2 of section 33.1-20-08-08, then minimizing unavoidable impacts to the maximum
extent reasonable, and finally offsetting remaining unavoidable wetland impacts
through all appropriate and reasonable compensatory mitigation actions (e.g.,
restoration of existing degraded wetlands or creation of man-made wetlands);
and
(5) Sufficient information is
available to make a reasoned determination with respect to the demonstrations
listed in paragraphs 1 through 4.
b. The owner or operator of the CCR unit
shall complete the demonstrations required by subdivision a by the date
specified in either paragraph 1 or 2.
(1) For
an existing CCR surface impoundment, the owner or operator shall include the
demonstration with the application for a permit modification that meets the
requirements of this chapter within twenty-four months of July 1, 2020, as
required by subsection 9 of section 33.1-20-08-02.
(2) For a new CCR landfill, new CCR surface
impoundment, or any lateral expansion of a CCR unit, the owner or operator
shall include the demonstration with the application for a new permit or permit
modification.

is considered complete when the demonstration is approved by the department and
placed in the facility's operating record.
(4) An owner or operator of an existing CCR
surface impoundment who fails to make the demonstration showing compliance with
the requirements of subdivision a by the date specified in paragraph 1 is
subject to the closure requirements of paragraph 1 of subdivision b of
subsection 2 of section 33.1- 20-08-07.

lateral expansions of existing CCR units that fail to demonstrate compliance,
waste is prohibited from being placed into the CCR unit.
3. Fault areas.
a. New CCR landfills, existing and new CCR
surface impoundments, and all lateral expansions of CCR units must not be
located within two hundred feet [60 meters] of the outermost damage zone of a
fault that has had displacement in Holocene time unless the owner or operator
demonstrates by the dates specified in subdivision c that an alternative
setback distance of less than two hundred feet [60 meters] will prevent damage
to the structural integrity of the CCR unit.
