2) SAFETY CONCERNS:
Hard hat, safety shoes, ear plugs and safety glasses are required. Watch for truck traffic.
3) FACILITY/PROCESS DESCRIPTION:
Murphy-Brown, LLC —Bladenboro Feed Mill is an animal feed manufacturing mill. They receive corn,
soybean, grain, and by-products at two(2)truck-receiving pits where there is one(1)fabric filter installed
to control dust and one uncontrolled rail-receiving pit. All soft ingredients are transferred to the interior
structure of the mill via one of two (2) receiving systems, each of which has a bagfilter installed. Corn
and grains pass through one (1) of four (4) hammer mills (where each pair of hammer mills is controlled
by a single bagfilter) and then to their respective bins. Liquid fat is pumped directly into a bin from the
truck. Vitamins and minerals are transferred, via a pneumatic receiving system controlled by a bagfilter,
from the truck to the interior structure of the mill. Materials are then weighed(how much depends on the
feed they are making) and blended to make feed mash. The mash is then sent through one(1) of three(3)
pellet mills, and then the pellets go into one (1) of three (3) pellet coolers, controlled by three (3) high
efficiency cyclones installed in parallel on each one of the coolers. After the feed has cooled it is loaded
onto trucks and shipped to the farms. The facility has two (2) NG/No. 2 fuel oil-fired boilers, normally j
operating on NG,that provide steam for the manufacturing operations.

5) INSPECTION SUMMARY:
On 18 May 2016, I, Heather Carter, arrived at Murphy-Brown, LLC — Bladenboro Feed Mill facility to
conduct their annual compliance inspection. I met with the new facility contact, Mr. Brian Franklin, Mill
Manager. Since this is the first inspection for which Mr. Franklin has been the point of contact, we
reviewed the entire permit. We reviewed the records required for GACT 7D (Feed Mfg NESHAP),
GACT 4Z(RICE NESHAP), bagfilters and cyclones, and facility throughputs. Recordkeeping was much
improved from previous years, but there was still a deficiency with respect to the NESHAP 7D, as
discussed in detail under the appropriate permit stipulation below. Mr. Franklin informed me of the
following updates for the facility: they would be notifying this office of an upcoming name change for
the facility, they had completed like-for-like replacements of their coolers, cyclones, and fans, and they
had not received any complaints since the last inspection that he was aware of. He also stated that they
had not been routinely exercising the emergency generator, but that they intended to start running it
monthly for testing. We toured the facility and found it to be relatively clean and observed 0% VE from
all operating sources.
6) PERMIT STIPULATIONS:
A. A.2. Permit Renewal and Emission Inventory Requirement —entire facility subject. Permit
renewal request and emission inventory due at least 90 days prior to permit expiration.
Appeared in Compliance — CY 2013 renewal and EI due 30 Jan 2015, both submitted on 30 Jan
2015. Next inventory due Nov 2022 for CY 2021. k
B. A.3. 2D.0503,"Particulates from Fuel Burning Indirect Heat Exchangers"—subject sources are f
boilers (ES-014 &ES-013). Boilers limited to 0.41 lbs PM/mmBtu.
Appeared in Compliance — Boilers combust primarily NG, using fuel oil only for backup during
curtailment/testing/supply interruptions. AP-42 PM emission factor for NG is 0.007 lb/mmBtu and
for No. 2 fuel oil is 0.02 lb/mmBtu, both of which are well below the limit.
C. A.4. 2D .0515, `Particulates from Miscellaneous Industrial Processes" —all sources subject,
except for boilers, generator and dryer. PM from these sources shall not exceed the allowable
emissions rate determined by E=55x(P)°11 -40.
Appeared in Compliance - Highly efficient fabric filters and high efficiency cyclones control
particulate emissions. Sources are operated the same as during last permit renewal evaluation.
Nothing indicates non-compliance.
i
D. A.5. 2D .0516, "Sulfur Dioxide Emissions from Combustion Sources" — subject sources are the
boilers (ES-013 &ES-014), generator(ES-016), and grain dryer(ES-019). Sources are limited to 2.3
lbs SO2/mmBtu.
Appeared in Compliance - Facility records indicate exclusive use of NG in the boilers, with use of
low sulfur #2 fuel oil only when curtailed by gas company; exclusive use of NG in dryer; and
exclusive use of low sulfur fuel oil in generator. Facility has not used fuel oil in the boilers since
2005. AP-42 S02 emissions factor for NG is 0.0006 lbs/mmBtu, and for No. 2 fuel oil is 0.51
lb/mmBtu,both well below the limit.
i
E. A.6. 2D .0521, "Control of Visible Emissions" — subject sources are boilers, generator & grain
j dryer. These sources are limited to 20% opacity.
j Appeared in Compliance — At the time of inspection, 0% opacity was observed from both boilers
operating on NG. Boilers normally operate on NG and only use fuel oil as a backup. The new grain
dryer was installed and ran in 2015, but was not operating during the inspection. The generator was
also not operating at the time of inspection. Mr. Franklin stated that that they never see smoke from
the boilers,but if they did they would shut it down and investigate and take corrective action.
F. A.7. 2D .0524, "New Source Performance Standards" — subject sources are the boilers. Sources
are limited to 0.5% sulfur by weight in the fuel combusted. Requires monthly fuel use records and
semi-annual reporting.
Appeared in Compliance — Natural gas is the primary fuel; fuel oil has not been combusted since
2005. Mr. Franklin had a log of fuel burned, which indicated zero fuel oil used in 2015 and thus far
in 2016. He was not able to produce the receipt (which shows the sulfur content) from their last
shipment of no. 2 fuel oil. He stated that since this fuel is only used in the engine used to move the
railcars on site,they have not been storing these receipts. I reminded him that if they burn fuel oil for
any reason, they would need to be able to show the sulfur content did not exceed 0.5% by weight.
Semi-annual reporting has been on-time (most recent received 1/29/16) and appeared valid and
complete.
i
G. A.8 2D .0535, "Notification Requirement" — subject sources are entire facility. Requires
notification of excess emissions that lasts more than 4 hours.
Appeared in Compliance - Mr. Franklin stated that to the best of his knowledge this facility has had
no excess emissions since the last inspection.
H. A.9. 2D .0540, "Fugitive Dust Control Requirement." — subject source is entire facility. The
Permittee shall prevent fugitive emissions from the facility from causing or contributing to
substantive complaints or excess VE beyond the property boundaries.
Appeared in Compliance—I noticed no dust emissions leaving the property when entering/exiting the
facility. No complaints have been received in the FRO DAQ or at the facility, according to Mr.
Franklin, since the last compliance inspection. The facility has a process in place to record and
address complaints if they are received.
1 I. A.10. 2D .0611,"Fabric Filter Requirement'—subject devices are those operating on the hammer
mills, truck receiving, ground grain negative air system, pneumatic receiving, mixed feed turnheads,
and receiving turnheads. Requires at least an annual internal inspection, and periodic I&M per
manufacturer specs.
Appeared in Compliance — Annual internal inspection records for each device were reviewed and
1� appeared complete and valid. The last inspection date ranges from 1/8/16 to 1/16/16. The facility
I
I
also monitors, daily, the magnahelic gauge reading on each bagfilter as a way to ensure proper
operation of the device and when problems are found corrective action is taken. The second
pneumatic receiving line is not functional and the baghouse(CD-133)was removed in Sept 2014.
J. A.11. 2D.0611,"Cyclone Requirement"—subject devices are those operating on the pellet coolers.
Requires at least an annual inspection.
Appeared in Compliance - At least one annual inspection has been conducted on each device in the
last 12 months (ranging between 2/11/16 —2/12/16). The facility inspects the cyclones for corrosion,
erosion and any other structural damage every month, and also inspects for buildup internally on a
quarterly and annually schedule.
K. A.12. 2D .1111,Prepared Feeds Manufacturing NESHAP (GACT 7D)- subject sources are areas
of plant at the point of and after the introduction of Manganese and/or Chromium into the feed mix.
Requirements include: recordkeeping of monthly housekeeping duties, monthly load-out chute
inspections, and quarterly cyclone inspections; storing chromium/manganese raw materials in closed
containers; operating cyclones according to good air pollution practices; preparing an annual
compliance certification (ACC) by March I", submitting to the DAQ only if deviations have
occurred.
Deficiency Noted - Records provided for the monthly housekeeping activities and quarterly cyclone
inspections appeared complete and valid. The monthly load-out chute inspections were recorded
through January 2016. Mr. Franklin stated that the forms were changed by their parent company and
that the line item for this inspection was missing. He stated that the employee doing the inspections
has not altered his routine and was still doing the inspections, the form just doesn't capture the info.
He immediately made changes to the form to start tracking this info. The facility actually has two
sets of eyes on the cyclones quarterly, operators and maintenance both perform inspections. Facility
also continues to record fan amperages on a daily basis, which is a great indicator on how the cyclone
is operating; additionally, the facility has an automated alarm system on each cyclone that notifies the
operator if the bindicator on the auger under each cyclone has stopped moving, indicating a plugged
cyclone. The system automatically shuts the pellet coolers down until the auger is unclogged.
Micronutrients containing Chromium and Manganese are received in bags/sacks varying in weight
but all are hand opened and poured into the small, lidded bins above the mixer. The bin lids are only
open when materials are being added. Mr. Franklin did have copies of previous ACCs on site; the
most recent being the CY 2014 ACC dated 2/25/15. However, he was missing the CY 2015 ACC.
He prepared the document and emailed it to me the next day. I reminded Mr. Franklin that the ACC
is to be prepared by 1 March every year for the preceding year, and that only if there are deviations
would they submit the ACC to FRO DAQ. Therefore, for the CY 2016 ACC, he would need to note
a deviation(not preparing the 2015 ACC by the due date)and submit to this office.
L. A.B. 2D .1111, Reciprocating Internal Combustion Engine NESHAP (GACT 4Z)— subject
source is engine for the generator. Requires a non-resettable hour meter be installed; operating less
than 100 hrs/yr for maintenance/readiness testing; and annual maintenance including: changing oil
and oil filter, and inspecting air cleaner and hoses/belts.
Appeared in Compliance—The engine is classified as an emergency engine b/c it only runs when the
facility is without power beyond their control. The facility does participate with 4-County Electric in
"load control" operations, where they voluntarily shutdown main energy sources (i.e. pellet coolers
and mixer), but the generator does not come on in that situation. They still use small amounts of
electricity from the grid to run receiving and load-out operations. The generator only comes on if the
facility is completely without power, and then it only runs receiving and load-out operations. The
most recent records provided for annual inspection and maintenance were dated 9 November 2015
and performed by outside contractor, Cummings Atlantic. The generator has a non-resettable hour
meter. I did not verify the number of hours on the non-resettable hour meter during this inspection.
M. A.M. 2D .1806, "Control and Prohibition of Odorous Emissions" -entire facility subject. The
facility shall prevent odorous emissions from causing or contributing to objectionable odors beyond
the property boundaries.
Appeared in Compliance - I detected no odors offsite when entering/departing the facility. No
complaints have been received in the FRO DAQ or at the facility, according to Mr. Franklin, in the
past year. The facility has a process in place to record and address complaints if they are received.
N. A.15. 2Q .0315,"Limitation to Avoid Title V"-entire facility subject. Limitation: PM10 emissions
shall not exceed 100 tpy. Restrictions: feed production is limited to 1,600,000 tons/yr; Grain dried is
limited to 200,000 tons/yr; Bagging operation is limited to 50,000 tons/yr. Requires monthly
_ recordkeeping and annual totals.
Appeared in Compliance-Monthly records appeared valid and complete. Tons of feed produced in
2015= 711,285 tons. Grain dried in 2015= 36,607 tons. Grain bagged in 2015= 42,121 tons. All
processes are well below permit limits.
O. A.16. 2Q .0317, Avoidance of Boiler NESHAP (GACT 6J)- would-be subject sources are the
boilers. Facility avoids applicability of this rule by burning NG, with fuel oil only as back-up during
emergencies/supply interruptions, testing and curtailment. Requires recordkeeping of fuel oil usage
and reason for usage. Notify DAQ within 30 days of switch to fuel oil outside of emergencies/supply
interruptions,testing and curtailment.
Appeared in Compliance -Facility burns NG exclusively, with fuel oil only burned as backup. No
i fuel oil has been burned since 2005.
P. A.17. 2Q .0711, "Toxic Air Pollutant Emissions Limitation"- subject sources are the entire
facility. Facility-wide emissions shall not exceed TPERs.
Appeared in Compliance -Compliance was determined during the most recent permit review, based
on the sources operating as described. Sources are operated the same as during last permit evaluation.
Nothing indicates non-compliance.
