(24) the owner or operator shall ensure that each commercial
industrial nonhazardous waste landfill unit meets the requirements
of subparagraphs (A) - (F) of this paragraph.
(A) Design criteria.
(i) Landfill cells shall be designed and constructed
in accordance with subclause (I) or (II) of this clause, and shall
also be constructed in accordance with subclause (III) of this clause.
(I) a design that ensures that the concentration values
for constituents listed in §330.419(a) of this title (relating
to Constituents for Detection Monitoring) will not be exceeded in
the uppermost aquifer at the point of compliance, as specified by
the executive director under clause (iv) of this subparagraph; or
(II) a composite liner, as defined in clause (ii) of
this subparagraph, and a leachate collection system that is designed
and constructed in accordance with subparagraph (B) of this paragraph;
and
(III) unless the executive director approves an engineered
design that the applicant has demonstrated will provide equal or greater
protection to human health and the environment, a landfill cell must
be constructed where the base of the containment structure, which
includes the sides and bottom of the containment structure, is at
least five feet above the uppermost saturated soil unit having a Unified
Soil Classification of GW (well-graded gravel), GP (poorly-graded
gravel), GM (silty gravel), GC (clayey gravel), SW (well-graded sand),
SP (poorly-graded sand), or SM (silty sand), or a hydraulic conductivity
greater than 1 x 10-5 cm/sec, unless
such saturated soil unit is not sufficiently thick and laterally continuous
to provide a significant pathway for waste migration.
(ii) For purposes of this section, "composite liner"
means a system consisting of two components. The upper component shall
consist of a minimum 30-mil (0.75 mm) geomembrane liner and the lower
component shall consist of at least a three-foot layer of compacted
soil with a hydraulic conductivity of no more than 1 x 10-7 cm/sec.
Geomembrane liner components consisting of high density polyethylene
shall be at least 60-mil thick. The geomembrane liner component must
be installed in direct and uniform contact with the compacted soil
component.
(iii) When approving a design that complies with clause
(i)(I) of this subparagraph, the executive director may consider at
least the following factors:
(I) the hydrogeologic characteristics of the facility
and surrounding land;
(II) the climatic factors of the area; and
(III) the volume and physical and chemical characteristics
of the leachate.
(iv) For purposes of this paragraph, the point of compliance
is defined in §330.3 of this title (relating to Definitions).
In determining the point of compliance, the executive director may
consider at least the following factors:
(I) the hydrogeologic characteristics of the facility
and surrounding land;
(II) the volume and physical and chemical characteristics
of the leachate;
(III) the quantity, quality, and direction of flow
of groundwater;
(IV) the proximity and withdrawal rate of the groundwater
users;
(V) the availability of alternative drinking water
supplies;
(VI) the existing quality of the groundwater, including
other sources of contamination and their cumulative impacts on the
groundwater and whether groundwater is currently used or reasonably
expected to be used for drinking water;
(VII) public health, safety, and welfare effects; and
(VIII) practicable capability of the owner or operator.
(B) Landfill cells shall have a leachate-collection
system designed and constructed to maintain less than a 30-cm depth
of leachate over the liner. The leachate-collection and leachate-removal
system shall be:
(i) constructed of materials that are chemically resistant
to the leachate expected to be generated;
(ii) of sufficient strength and thickness to prevent
collapse under the pressures exerted by overlying wastes, waste cover
materials, and by any equipment used at the landfill; and
(iii) designed and operated to function through the
scheduled closure and post-closure period of the landfill.
(C) Storm water run-on/run-off facilities such as berms
and ditches shall be provided in accordance with §330.63 of this
title (relating to Contents of Part III of the Application).
(D) The site shall have a groundwater monitoring system
installed that is capable of detecting the migration of pollutants
from the landfill and is sampled semiannually for the parameters specified
in Chapter 330, Subchapter J of this title (relating to Groundwater
Monitoring and Corrective Action).
(E) The final cover placed over the commercial industrial
nonhazardous waste landfill unit shall consist of a minimum of 18
inches of uncontaminated topsoil overlying four feet of compacted
clay-rich soil material meeting the requirements of §330.457
of this title (relating to Closure Requirements for Municipal Solid
Waste Landfill Units That Receive Waste on or after October 9, 1993).
The final cover over the aerial fill shall meet the requirements of §330.457
of this title and shall include a flexible membrane component.
(F) Nonhazardous waste may be placed above natural
grade in commercial industrial nonhazardous waste landfill units provided
the conditions in clauses (i) - (vi) of this subparagraph are met,
except as provided in clause (vii) of this subparagraph:
(i) waste placed above grade shall be laterally contained
by dikes that are constructed to:
(I) prevent washout, release, or exposure of waste;
(II) be physically stable against slope failure, with
a minimum safety factor of 1.5;
(III) prevent washout from hydrostatic and hydrodynamic
forces from storms and floods;
(IV) prevent storm water from reaching the waste;
(V) minimize release of leachate; and
(VI) minimize long-term maintenance;
(ii) the liner required in paragraph (22) of this section
shall extend to the crest of the dike;
(iii) waste placed against the dike is placed no higher
that three feet below the crest of the dike;
