saved approximately $1-$2 million in
up-front costs versus the other closure
methods considered, not including the
additional long-term maintenance savings of traditional cap options.
The in-place closure process includes
the removal of surface waters and isolation of the CCR unit, CCR grading,
construction quality assurance (CQA)
services and construction management
activities. Water management is variable
between sites and between ash ponds
on the same site (Figure 3). Retaining
experienced contractors and providing
comprehensive hydrogeologic information to contractors can mitigate construction issues associated with managing
saturated material early in the project that
affect the project as a whole.

CQA services involve third-party
quality assurance activities on these projects. These included sampling and testing
of the subgrade, soils and geosynthetics,
both in the field and in laboratories. CQA
activities for geomembranes and the geomembrane components of structured
geomembrane/turf component system
are standardized and include air channel
testing and vacuum box testing. A traditional Subtitle D cap requires observation
and testing of soil cover and vegetation
while the structured geomembrane/turf
component system requires observation
of the turf seaming, sand installation and
sand/epoxy or sand/concrete mix placement (Figure 4). Qualified contractors
and geosynthetic installers can save an
owner a significant amount of time and

The chosen method
saved approximately
$1-$2 million in upfront costs versus the
other closure methods
considered, not

long-term maintenance
savings of traditional
cap options.

Geomembranes that contain.
Liners that control.
Barriers that comply.

By forming a flexible, durable barrier that's
engineered to withstand most liquids and
chemicals, Plastatech® geomembranes are
highly effective in groundsheet and leach pad
applications or for freshwater, runoff or spill
containment. They help you control the site and
comply with regulations.*
