COAL ASH MANAGEMENT
" The design of this
project incorporates
the environmental
criteria which will
be the standard for
next-generation
landfills. "
-Bobby Raia, Charah project
coordinator
Upon completion of construction,
Charah will begin the landfill management
phase, providing day-to-day operations
that will include hauling, placement, and
compaction of CCBs produced by CPSGI's
plants. Trucks owned and operated by
Charah will haul CCBs from the plants to
the landfill and will feature a cable-type
6. Hands-on management. CPSGI

tarp system that encapsulates the CCBs,
thus avoiding and controlling any potential
for dusting during transit. After placing the
CCBs within the active working area, and
prior to leaving the landfill site, trucks will
travel through a self-contained truck and
wheel wash system. The system includes
a wash unit and recycling/filtration tank
designed to clean and remove any CCB
residue that may remain on the truck prior
to returning to the public roadways. Any
potential for onsite dusting will be further
controlled by watering the access road,
and other landfill areas as needed, via water
truck (Figure 6).
To secure the active area and avoid dusting
after hours, Charah will apply hydromulch
on a daily basis across the exposed
CCB surface. Hydro-mulch is a hydrated
straw mulch that contains tacking agents
that allow the material to adhere to the
CCBs. The hydro-mulch will provide an
initial barrier that will mitigate any possible
wind or stormwater runoff erosion.■
