3) Inspection Conference
On 29 July 2010, I (Cindy Grimes of DAQ FRO),met with the facility contact/plant manager, Chris
Tucker. This compliance inspection was prearranged, since it for permit renewal. We discussed the
following;
a) I verified the FACFINDER information. The Invoice Contact will change from Laura Lingerfelt
to Pam Thomas in Accounts Payable(phone#[phone]). Mr.Tucker remains the contact for
Facility,Technical and Authorized.
b) No equipment or sources have changed since the last compliance inspection in 2009.
c) With production still being down due to the economy, this facility is only producing 2-3 days per
week,with a crew of 2 employees. The workload varies,with some weeks having 1 '/2 loads to
others with 7 loads (1 load=24 tons).
d) Mr. Tucker will try to submit the emissions inventory on his own.At first, he said he would submit
the inventory on paper,but then I walked him through the AERO process and encouraged him to
submit it online.
e) Mr. Tucker asked about changing the load out of the sand trucks from pneumatic to conveyor with a
hopper.I told him he could discuss it with either Greg Reeves or Jim Moser,both permit engineers at
FRO, during this permit renewal process.
4) 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. The bag filter vents to the
atmosphere. I did not observe any signs of overfilling around the silo.
b) Bagging Operation:The bagging operation 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. I observed this operation,
as the workers filled—5 bags while I was there. The area was clean, and I saw no problems.
c) Cyclone and Bagfilter: As the workers were bagging,I stepped out and observed these control devices.
I saw 5%VE and 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 come 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,and they stockpile the waste in an area behind the building.They take the
stockpiled waste 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.
5) Permit Stipulations
a) A.4 2D .0510 PARTICULATE CONTROL REQUIREMENT—"Particulates from Sand, Gravel, or
Crushed Stone Operations"—The Permittee shall reduce particulate matter, so as not to exceed ambient
air quality standards beyond property lines, and all operation emissions shall be controlled.
In Compliance—I did not observe any piles that would cause a problem beyond property boundaries.
The haul roads appeared to be adequately controlled.
b) A.5 2D .0521 VISIBLE EMISSIONS CONTROL REQUIREMENT—Visible emissions from
sources shall be less than 20%opacity.
In Compliance—This facility was operating during my inspection, and I observed 5%VE.
c) A.7 2D.0540 PARTICULATE CONTROL REQUIREMENT—The Permittee shall not cause or allow
fugitive non-process dust emissions to contribute to complaints.
In Compliance—Haul roads appeared to be adequately controlled during my inspection.
6) Reporting requirements
There are no reporting requirements for this facility in its current air permit.
7) 112R Status
Based on the facility's inventory, it was decided that they are not subject to 112R requirements.
8) 5 year Compliance History
a) 15 October 2007—NOV for improper operation and maintenance of bagfilter system and collection
barrels.
b) 16 September 2005—NOV for a continuing violation of operating without an air permit.
c) 20 August 2004—NOV for operating without an air quality permit.
9) Comments and Compliance Statement
The question came up during last year's inspection whether there should be the permit stipulation 2D .0611
for both the bagfilter and cyclone at this facility.At the time,I spoke with Robert Hayden and Jim Moser,both
of this office, and it was decided to pink sheet the comment in the facility's folder for this permit renewal.
Lisk Sand appeared to be in compliance on 29 July 2010.
