the volume of waste received daily and the nature of the industrial waste. A
lift height is not required for materials such as fly ash that are not
compactable.
c. Where it is
necessary for the specific waste, such as Category I or II nonfriable
asbestos-containing material, daily soil cover, or other suitable material
shall be placed upon all exposed solid waste prior to the end of each operating
day. For wastes such as fly ash and bottom ash from burning of fossil fuels,
periodic cover to minimize exposure to precipitation and control dust or dust
control measures such as surface wetting or crusting agents shall be applied.
At least three days of acceptable cover soil or approved material at the
average usage rate shall be maintained at the fill at all times at facilities
where daily cover is required unless an offsite supply is readily available on
a daily basis.
d. Intermediate
cover of at least one foot of compacted soil shall be applied whenever an
additional lift of refuse is not to be applied within 30 days unless the owner
or operator demonstrates to the satisfaction of the director that an alternate
cover material or an alternate schedule will be protective of public health and
the environment. In the case of facilities where fossil fuel combustion
products are removed for beneficial use, intermediate cover must be applied in
any area where ash has not been placed or removed for 30 days or more. Further,
all areas with intermediate cover exposed shall be inspected as needed but not
less than weekly and additional cover material shall be placed on all cracked,
eroded, and uneven areas as required to maintain the integrity of the
intermediate cover system.
e. Final
cover construction will be initiated in accordance with the requirements of
9VAC20-81-160 D 2 when the
following pertain:
