2) Facility and Process Description
Lisk Sand is a bulk hauling company that specializes in industrial and abrasive material hauling.This facility
is permitted under Air Permit No. 09580R01,effective from 12 October 2010 to 30 September 2015.
Cindy Grimes conducted the last compliance inspection on 29 July 2010.
Dried play sand is brought in from Unimen Corporation(a sand mining company) in Richmond County and
temporarily stored in a silo at Lisk Sand.The sand is bagged according to grade, such as play or blasting sand,
and then bagged and shipped.

Employees: 2 (same in 2009)
Horns: 8 hrs/day(not bagging all the time),2-3 days/week,50 weeks/year(same in 2009)

3) Inspection Conference
On 24 August 2011,I(Cindy Grimes of DAQ FRO)met with the facility contact/plant manager, Clods
Tucker, and we discussed the following:
a) I verified the FACFINDER information.
b) No equipment or sources have changed since the last compliance inspection in 2010, which was
for permit renewal.
c) With production being down due to the economy,this facility is still only producing 2-3 days per
week,with a crew of 2 employees.The workload varies, with some weeks having 1 % loads to
others with 7 loads (1 load=24 tons).
d) The facility had thoughtabout installing a conveyor for the sand loadout process(versus pneumatic),
but Mr. Tucker told me it wasn't cost effective right now. He said lie would inform FRO before they
ever made any changes.
4) Inspection(facility was not operating during inspection)
a) Storage Silo: The trucks offload sand from a line that runs from outside the bagging building into the
storage silo located inside. Currently, a 24-ton capacity storage silo is being used. The silo is filled
pneumatically and controlled by a cyclone that is ducted into a bag filter, which vents to the atmosphere.
I did not observe any signs of overfilling around the silo, and the area appeared reasonably clean.
b) Bagging Operation: The bagging process is a single station operation that is located inside an enclosed
building.A vacuum hose that connects to the cyclone/bag filter(in series)controls the bagging operation.
The bag filter empties into a 50-gallon drum that has a sealed rim connection;this drool is located on the
outside of the building. The area was clean,and even though no bagging was taking place,I saw no
problems.
c) Cyclone and Bagfilter: I saw no signs of overfill,holes,or duct compromises.The 2 workers here keep
a logbook with entries showing operating days(2-3 times/week) and any maintenance issues that cone
up. They also check for any dust emissions from the system when it's operating. They told me they
change out the dust barrel about once a month(this varies, depending on production),and they stockpile
the waste in an area behind the building. The stockpiled waste is taken to the landfill about 2-3 times a
year.I observed this area and found a small pile of the waste behind a buffer of vegetation. I did not see
any issues that would have found them non-compliant.This small area is well away from the road and
the facility's boundary. I suggested that they wet the pile if it ever gets very dry.
