5) Inspection Conference
On 2 September 2020,I Jeff Nelson of FRO DAQ conducted a compliance evaluation inspection of
the Adams Old Castle Company—Lilesville facility. I met with Eric Smith Plant Manager and Benji
Atkinson, Maintenance Manager. We met and discussed the following:
a) Verified the FACFINDER information: Mr. Smith noted that he was now the Plant Manager
and that Mr. Atkinson was the new Maintenance Manager. I noted the changes and made
appropriate edits in IBEAM.
b) We reviewed the facility's maintenance and inspection logbooks. Records appeared to be
complete and up to date.

6) Inspection Tour
Mr.Atkinson led me on a tour of the facility which was operating. Mr. Atkinson informed me that the
facility was continuing to use the Hi-Vac system that was installed to manage dust and clean up in the
bagging area. The Hi-Vac unit does not vent outside of the building it is housed in. The facility
appeared clean and well maintained.
I asked Mr.Atkinson what their procedure was for receiving dry material into the silos. He stated that drivers
are instructed to fill silos at 10 to 12 psi to avoid exceeding the rate of the bagfilters. Trailers have an over
pressure valve that is triggered if the fill pressure exceeds 15 psi.
7) Permit Stipulations
a) A.2 15A NCAC 2D .0202 &2Q .0304-PERMIT RENEWAL AND EMISSION
INVENTORY REQUIREMENT-The facility shall submit a permit renewal request and a
completed air emissions inventory at least 90 days prior to permit expiration.
APPEARED IN COMPLIANCE—The facility submitted their emissions inventory on 18
January 2017 and the permit renewal on 23 January 2017, before the required deadline. The
facility's next deadline for submittal will be December 2024 for the 2023 calendar year.

operations since that determination.
c) A.4 15A NCAC 2D .0516 SULFUR DIOXIDE CONTROL REQUIREMENT—S02
emissions from the combustion sources shall not exceed 2.3 lbs/mm BTU.
APPEARED IN COMPLIANCE—The AP-42 emissions factor for No.2 fuel oil is 0.002 lbs/mmBtu;
natural gas is 0.001 lbs/mmBtu. Facility is only burning natural gas.
d) A.5 15A NCAC 2D .0521 VISIBLE EMISSIONS CONTROL REQUIREMENT-Visible
emissions from the emission sources shall not exceed 20%opacity.
