CRUSHER, SCREEN AND TRANSFER POINTS
MITIGATION PROCEDURES
Each source of dust from these operations will be equipped with water
spray bars. This will include the crusher and its associated transfer
points, including the surge pile transfer point.
SURGE PILE
The surge pile is necessary since the silo holds only 8,500 tons of
coal whereas a typical train may accommodate over 10,000 tons; additional
coal must therefore be transported into the silo during the train loading
activities. A front end loader delivers coal from the surge pile to a
storage bin; from here a conveyor belt connects it to the silo loading
conveyor belt. This operation has several possibilities for generating
fugitive dust: 1) the activities of the front end loader moving around
on the coal pile, 2) the dumping of the coal into the bin, and 3) the
possibility of wind blown dust from the exposed surface.
MITIGATION PROCEDURES
The coal loading bin will be equipped with water sprays to control the
dust generated by loading coal from the front end loader. The front end
loader will use good housekeeping practices such as limiting the drop
height, maintaining the storage area in a neat and clean condition, and
minimizing the horizontal size of the surge pile.
Several mitigating measures will be used to control the fugitive wind
blown dust from the surge pile: 1) Proper scheduling will be used to
minimize the size of the pile, 2) A wind screen will be installed to the
east of the pile to break the wind patterns. This wind screen will
extend several feet to the south of the pile to minimize edge effects of
the screen. The north end of the screen will extend to the existing
W3
The coal is
transported to the
crusher
by a partially underground
conveyor belt.
The coal is loaded
into the crusher and after crushing
is then transported either directly
to the
silo or to an outside surge
pile. A screen
separates the smaller pieces
of coal for direct transport
to the silo or
surge pile with the
larger chunks going to the crusher.
The crusher and
transfer points are within a
partially enclosed building.
