The following factors need to be considered in
evaluating the landfill design:
(i) Waste characterization;
(ii) Soil conditions;
(iii) Hydrogeologic conditions;
(iv) Hydraulic conditions;
(v) Contaminant fate and transport;
(vi) Topography;
(vii) Climate;
(viii) Seismic conditions;
(ix) The total capacity of the facility and each
landfill unit;
(x)
Anticipated
leachate
characteristics
and
quantity;
(xi) Operational controls; and
(xii) Environmental monitoring systems.
Liner system design (3)(b)
Liner system performance standard. Limited
purpose landfills shall be constructed in accordance
with a design that will(3)(b)(i):
NA
if presumtive liner design per (3) (b)(v) is
approved.
Prevent the contamination of the
hydrostratigraphic units identified in the
hydrogeologic assessment of the facility at the
relevant point of compliance as specified
during the permitting process
Prevent the migration of methane and other
gases.
The JHD may allow a limited purpose landfill to be
designed and constructed without a liner system if
the owner or operator can demonstrate during the
permitting process that (3)(b)(ii):
NA
if liner system is used
The contaminant levels in the waste and
leachate are unlikely to pose an adverse impact
to the environment;
The ability of natural soils to provide a barrier
or reduce the concentration of contaminants
provides sufficient protection to meet the
performance standards of WAC 173-350-040

Liner separation from ground water. Bottom of
the lowest component of the liner system is less
than ten feet (three meters) above the seasonal high
level of ground water or a hydraulic gradient
control system has been installed which prevents
ground water from contacting the liner. (3)(b)(iii)
Hydraulic gradient control system performance
standard. If hydraulic gradient control system is
used:
NA
Demonstration included that the hydraulic gradient
control system can be installed to control ground
water fluctuations and maintain separation between
the controlled seasonal high level of ground water
in the identified water-bearing unit and the bottom
of the lowest liner system component. The
demonstration shall include (3)(b)(iv):
A discussion in the geologic and hydrogeologic
site characterization showing the effects from
subsoil settlement, changes in surrounding land
uses, climatic trends or other impacts affecting
ground water levels during the active life,
closure and post-closure periods of the landfill;
A discussion showing potential impacts of the
gradient control operation to existing quality
and quantity of ground water or surface waters.
This discussion shall include potential impacts
to water users and instream flow and levels of
surface waters in direct hydrologic contact or
continuity with the hydraulic gradient control
system. Any currently available ground or
surface water quality data for aquifers, springs,
or surface waters in direct hydrologic contact
or continuity with the hydraulic gradient
control system shall be included;
Conceptual engineering drawings of the
proposed landfill and a discussion as to how the
hydraulic gradient control system will protect
or impact the structural integrity and
performance of the liner system
Preliminary engineering drawings of the
hydraulic gradient control system
Design specifications for the proposed ground
and surface water monitoring systems;
A discussion of the potential impacts from the
gradient control system on the capability of
collecting ground water samples that will
represent the quality of ground water passing
the relevant point of compliance

Presumptive liner design. Limited purpose
landfills designed and constructed with the
following composite liner are presumed to meet the
performance standard of WAC 173-350-
400(3)(b)(i). An alternative liner system design
shall be used when the nature of the waste, the
disposal site, or other factors are incompatible with
the presumptive liner. The presumptive liner design
consists of the following two components (3)(b)(v):
A lower component consisting of at least a two-
foot layer of compacted soil with a hydraulic
conductivity of no more than 1 x 10-7 cm/sec.
An upper component consisting of a high-
density polyethylene (HDPE) geomembrane
with a minimum of 60-mil thickness. The
geomembrane shall be installed in direct and
uniform contact with the lower component.
Leachate collection and control system design.
Except as provided in (b)(ii) of this section, limited
purpose landfills shall be constructed in accordance
with a design that (3)(c):
Provides for collection and removal of leachate
generated in the landfill
Is capable of maintaining less than a one-foot
head of leachate over the liner system and less
than a two-foot head in leachate sump areas
Includes a monitoring system capable of
collecting representative samples of leachate
generated in the landfill; and
Provides for leachate storage, treatment, or
pretreatment to meet the requirements for
permitted discharge under chapter 90.48 RCW,
Water pollution control, and the Federal Clean
Water Act.
Run-on/runoff control system design. Limited
purpose landfills shall be constructed in accordance
with a design that (3)(c):
Will prevent flow onto the active portion of the
landfill during the peak discharge from a
twenty-five-year storm, as defined in WAC
173-350-100;
Will prevent unpermitted discharges from the
active portion of the landfill resulting from a
twenty-five-year storm, as defined in WAC
173-350-100;
When located in a one hundred-year floodplain,
the entrance and exit roads, and landfill
practices do not restrict the flow of the base
flood, reduce the temporary water storage
capacity of the floodplain or result in washout
of solid waste, to pose a hazard to human life,
wildlife, land or water resources.
Final closure system design (3)(e)

Final closure performance standard. Limited
purpose landfills shall be closed in accordance with
a design that (3)(e)(i):
Prevents exposure of waste
NA
if presumtive final closure cover is approved
Minimizes infiltration (at a minimum, the
design will prevent the generation of significant
quantities of leachate to eliminate the need for
leachate removal by the end of the post-closure
period)
NA
if presumtive final closure cover is approved
Prevents erosion from wind and water
NA
if presumtive final closure cover is approved
Is capable of sustaining native vegetation
NA
if presumtive final closure cover is approved
Addresses anticipated settlement, with a goal of
achieving no less than two to five percent slope
after settlement
NA
if presumtive final closure cover is approved
Provides sufficient stability and mechanical
strength and addresses potential freeze-thaw
and desiccation;
Provides for the management of run-on and
runoff, preventing erosion or otherwise
damaging the closure cover
Minimizes the need for post-closure
maintenance
Provides for collection and removal of methane
and other gases generated in the landfill.
Landfill gas shall be purified for sale, used for
its energy value, or flared when the quantity
and quality of landfill gases will support
combustion.
Landfill gases may be vented
when they will not support combustion. The
collection and removal system shall include a
monitoring system capable of collecting
representative samples of gases generated in
the landfill; and
Meets the requirements of regulations, permits
and policies administered by the jurisdictional
air pollution control authority or the department
under chapter 70.94 RCW, Washington Clean
Air Act and Section 110 of the Federal Clean
Air Act.
