Mich. Admin. Code R. 299.4910 - Landfill engineering plans; design plans and engineering reports
Rule 910.
(1)
Engineering plans for a landfill shall include detailed engineering plans of
the proposed design and an engineering report that details all of the following
for each disposal unit:
(a) Soils underlying
each liner system, as specified in subrule (2) of this rule.
(b) Compacted soil liners or natural soil
that is used in place of a compacted liner, as specified in subrule (3) of this
rule.
(c) Bentonite geocomposite or
flexible membrane liners, as specified in subrule (4) of this rule.
(d) Primary leachate collection and removal
systems, as specified in subrule (5) of this rule.
(e) Secondary leachate collection systems, as
specified in subrule (6) of this rule.
(f) Dewatering systems, as specified in
subrule (7) of this rule.
(g) Other
control systems, as specified in subrule (8) of this rule.
(h) The final cover, as specified in a
closure plan that is in compliance with R 299.4446.
(i) Postclosure maintenance and monitoring,
as specified in a plan that is in compliance with R 299.4447.
(2) An engineering report on the
characteristics of soils underlying any liner shall include all of the
following information:
(a) A settlement
analysis that estimates total and differential settlement, including immediate
settlement, primary consolidation, and secondary consolidation based on maximum
loading.
(b) A slope stability
analysis.
(c) A performance
analysis under varying groundwater conditions.
(d) Calculations that show the potential for
bottom heave or blowout.
(3) An engineering report on the soils that
are likely to be used for any compacted or natural soil liner shall include all
of the following information:
(a) The location
and thickness of soils to be used for the compacted or natural soil
liner.
(b) Copies of well or boring
logs that document the soil deposit.
(c) Data documenting that the soil source is
in compliance with the soil classifications specified in R 299.4913.
(d) For compacted soil liners, calculations
which show that the volume of the source is sufficient for liner
construction.
(4) An
engineering report on any bentonite geocomposite or flexible membrane liner to
be used shall include all of the following information:
(a) The methods of storage, handling, and
installation, including any written instructions from the manufacturer, and
procedures for complying with the quality control requirements of R 299.4914
and R 299.4915.
(b) The physical
specifications of the liner material.
(c) The ability of liner material and scrim
material, where applicable, to maintain physical properties under varying
conditions of temperature, pH, ultraviolet radiation, biological attack, and
prolonged leachate contact throughout the operating and postclosure life of the
landfill.
(5) The
engineering plans for a landfill shall contain an engineering report on the
design of the leachate collection and removal system. The report shall include
all of the following information:
(a)
Specifications for the material to be used for the leachate collection
system.
(b) The design of the
collection pipe, including all of the following information:
(i) Diameter.
(ii) Perforations.
(iii) Slope.
(iv) Spacing.
(v) Leachate compatibility.
(vi) Structural integrity under static and
dynamic loadings.
(c)
Design features that allow cleaning of drainage pipes within the
system.
(d) Procedures to prevent
clogging during construction and operation.
(e) Calculations to show that the leachate
head will be 1 foot or less above the liner at any point in the system, except
the sump.
(f) Provisions to remove
obstructions from the system.
(g)
Calculations to determine the anticipated volume of leachate to be
generated.
(h) Information on the
proposed method of disposal for the leachate collected.
(6) An engineering report on a secondary
collection or leak detection system shall include the information specified in
both of the following provisions:
(a) The
information required under subrule (5) of this rule.
(b) The method of detecting, removing, and
analyzing any leaks that are detected in the system.
(7) The engineering plans for a landfill
shall contain an engineering report for any dewatering systems to be used. The
report shall include all of the following information:
(a) Design calculations for the drain pipe
diameter, slope, and spacing.
(b)
Design features that allow cleaning.
(c) Procedures to prevent clogging during
construction and operation.
(d) An
evaluation of the structural suitability of underdrain pipe under both static
and dynamic loadings.
(8) The engineering plans shall contain
information on systems to control all of the following:
(a) Run-on.
(b) Runoff.
(c) Wind dispersal of particulate matter,
where applicable.
(d) Gas that is
generated within the landfill.
(9) Engineering plans for a landfill shall be
prepared and sealed by a professional engineer registered in the State of
Michigan.
