Construction of landfill components is an integral part
of site development. Detailed engineering construction plans
and technical specifications are prepared prior to beginning
construction.
Some key personnel and their functions
related to landfill construction include:
Soils Pre-Qualification
All soils utilized for landfill construction are pre-qualified
in a soils laboratory to confirm soil properties in accordance
with design specifications. All soils lab data is submitted
to the OEPA prior to using them in landfill construction.
Depending on the type of soils and landfill construction
components, soil testing is conducted at a frequency of
one test for every 1,500 cubic yards of soils.
Test Pad Construction
Test pad construction is a unique construction method used
in Ohio. After recompacted clay liner soils are pre-qualified,
a test pad is constructed to mimic the construction techniques
utilized in the landfill construction. The test pad documents
the soils placement procedures, soils processing techniques,
moisture application, and compaction procedures. Upon completion
of a test pad, permeability of the constructed soil liner
is verified by installation of devices that measures horizontal
and vertical permeability. A test pad construction report
is submitted to the OEPA for review and approval.
Field Activities
Professional engineers monitor construction activities
on a daily basis. Daily reports are prepared documenting
construction activities such as field-testing of all soils
and geosynthetic components in accordance with the specifications.
Certification Report
Upon completion of construction activities, a comprehensive
construction certification report is submitted to the Ohio
EPA for approval. Waste is placed in the new areas after
the Ohio EPA approves the construction certification.
The certification report includes:
