GFA has been
providing engineering services at the Finley Buttes Regional
Landfill since 1999.
Services that
have been provided include: analysis of development options; assistance
in obtaining regulatory agency approval for a vertical landfill
expansion;
preparation of site development plan and landfill operating plan;
preparation of an alternative liner system analysis; preparation of
an alternative final cover system analysis; coordination of an
alternative final cover demonstration project performed in
conjunction with the EPA; preparation of plans and specifications
for the construction of Cell 4b and the landfill’s gas collection
and control system; preparation of fill sequencing plans;
preparation of soil management plans; preparation of a construction
quality assurance plan; contract management assistance; and CQA
certification.
As part of the engineering services that have been
provided, GFA working in conjunction with Waste Connections prepared
the design for a 100 million cubic yard vertical expansion to the
landfill. The maximum height of the landfill was increased by over
200-feet. Renderings were developed which showed the landfill at
completion. Review of the expansion plans included numerous
meetings with the DEQ and the public.
Approval for the expansion was received in 2003. At
current disposal rates, WCI now has a landfill with over 100 years
of remaining disposal capacity. |
