SAFETY.CONCERNS: Hard hat, safety shoes, ear plugs and safety glasses are required. SOURCE/FACILITY DESCRIPTION: Murphy-Brown, LLC—Bladenboro Feed Mill is an animal feed 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 one (1) of two (2) pneumatic receiving systems each with a bagfilter installed, from the truck to the interior structure of the mill. Only one pneumatic receiving system currently operates, the other is disconnected and the baghouse is just a shell. 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, there are 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.

I met with Mr. Doug Hinson, Plant Superintendent. We discussed the requirement for fuel usage records and fuel oil supplier certification, and I reviewed housekeeping and load-out(as required by GACT 7D)records. The facility has recently had turnover of staff that dealt with retrieving info from their maintenance records system (METHOS) and was not able to pull up bagfilter and cyclone inspection/maintenance records during the inspection. Mr.Hinson later emailed me copies of bagfilter and cyclone records obtained from the system. The facility still uses NG for the boilers and only uses low sulfur fuel oil (per vendor certification) as a back-up. The train engine and the generator use ultra-low sulfur fuel oil and the same tank supplies all sources. There were no new complaints recorded since the previous compliance inspection. The following issues need to be addressed in the equipment list in their current permit: • ES-001 is actually two pits controlled by one bagfilter; • currently onsite is a 1533 sqft bagfilter operating on two hammer mills and a 803 sq ft bagfilter operating on the other two hammer mills, Mr. Hinson stated that they have purchased two new bagfilters (model # 100AST-10) having 1640 sqft of filter area to replace both the old units. However, the air permit indicates there will be a 1640 sq ft bag filter and a 1620 sq ft bag filter installed. While on top of the mill, observing the emission points from several control devices, I noted that the receiving pit elevator leg above the top of the mill had a hole in it that was allowing small amts of particulate to become airborne. Mr. Hinson noticed it also and instructed an employee to temporarily plug the hole until a metal patch could be added during the week of Nov 12", when maintenance shutdown was scheduled. PERMIT STIPULATIONS: A.2. Permit Renewal and Emission Inventory Requirement—subject sources are the entire facility. Appeared in Compliance - submitted the permit renewal application and CY 2008 EI on time, next inventory due Jan 2015 for CY 2013. A.3. 2D .0503, "Particulates from Fuel Burning Indirect Heat Exchangers" — subject sources are boilers(ES-014 &ES-013) Appeared in Compliance —Nothing to indicate non-compliance. Sources are operated same as during last permit renewal evaluation. Boilers combust NG,using fuel oil only for backup during curtailment. A.4. 2D .0515, `Particulates from Miscellaneous Industrial Processes" — subject sources are all sources,except for boilers and generator. Appeared in Compliance-Nothing to indicate non-compliance. Sources are operated same as during last permit renewal evaluation. Highly efficient fabric filters and triple high-efficiency cyclone banks control particulate emissions. Intermittent opacity was observed from the receiving pit elevator leg on top of the mill. Mr. Hinson noticed same and instructed an employee to plug the hole until the scheduled maintenance shutdown the following week when they could repair the hole with a metal patch. A.S. 2D .0516, "Sulfur Dioxide Emissions from Combustion Sources" — subject sources are the boilers(ES-014 &ES-013), generator(ES-016),and grain dryer(ES-006). Appeared in Compliance - facility records indicate exclusive use of Natural Gas in the boilers, with use of low sulfur 42 fuel oil (per vendor's certified statement)only when curtailed by gas company. Facility hasn't used fuel oil in the boilers since 2005. The grain dryer uses NG only, and the generator operates on low-sulfur diesel (per vendor's certified statement) and only runs once a month for testing and maintenance. A.6. 2D .0521,"Control of Visible Emissions"—subject sources are boilers, generator&grain dryer. Appeared in Compliance—At the time of inspection, 0% opacity was observed from the boiler operating on NG. Boilers normally operate on NG and only use fuel oil as a backup. The grain dryer was not operating. It only runs approx 1 month out of a year(September time frame). The generator was also not operating at the time of inspection. Mr. Hinson says that they never see smoke from the boilers. A.7. 2D .0524,"New Source Performance Standards"—subject sources are the boilers. Appeared in Compliance— Generally, the semi-annual reports have been received on time. The reports indicate compliance with the standard in that the last shipment of fuel oil received contained <0.5% sulfur. The facility also had on site at least 2 years of weekly fuel combustion records (the requirement is for monthly records). Natural gas is the main fuel used. Fuel oil supplier certification is also on site. A.8 2D .0535,"Notification Requirement"—subject sources are entire facility. Appeared in Compliance - Mr. Hinson stated that to the best of his knowledge this facility has had no excess emissions that exceeded limits for more than four hours. A.9. 2D .0540,"Fugitive Dust Control Requirement."—subject source is entire facility Appeared in Compliance—When entering and exiting the facility I noticed no dust emissions leaving the property. No complaints have been received in the FRO DAQ or at the facility, according to Mr. Hinson, since the last compliance inspection. The facility has a process in place to record and address complaints as they are received. 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. Appeared in Compliance - Records document routine inspections and maintenance on these devices. At least one annual inspection has been conducted on each device in the last 12 months. A.11. 2D .0611,"Cyclone Requirement"—subject devices are those operating on the pellet coolers. Appeared in Compliance - Records document routine inspections and maintenance on these devices. At least one annual inspection has been conducted on each device in the last 12 months. A.12. 2D .1111,Reciprocating Internal Combustion Engine NESHAP (GACT 4Z)—subject source is generator Appeared in Compliance — The compliance date for this rule has not yet passed. The generator is classified as an emergency engine b/c it only runs when the facility is without power beyond their control. When the facility participates with 4-County Electric in "load control" operations, 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 amts of electricity from the grid to run receiving and load-out operations. As a courtesy, I emailed Mr. Hinson the compliance requirements for this engine. A.13. 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. Appeared in Compliance-The compliance date for this rule was Jan 5,2012. FRO DAQ received the IN and NOCS by the due dates. They appear to be in compliance with the housekeeping activities and bagfilter/cyclone inspections; however the facility is not keeping records of monthly load-out sock inspections as required by the rule. It appears, based on visual observations, that they are monitoring the performance of the load-out socks,just not recording this activity. The truck load-out socks are cloth and are approx 1/2 ft-lft from the top of the truck, from rear to front because of the gradient in the load-out. The required quarterly cyclone inspections are exceeded by the combination of weekly and monthly inspections conducted by facility personnel. Facility personnel continue to record fan amperage on a daily basis even though the rule was changed and this requirement is only for new facilities. The detailed permit stip was added to this most recent permit. I explained the annual compliance certification (ACC) requirement, due 1 March 2013; specifically that the missing records constitutes a deviation and must be noted in the ACC and since there are deviations the ACC must be submitted to FRO DAQ. A.14. 2D.1111,Boiler NESHAP(GACT 6.n- subject sources are boilers Appeared in Compliance—The compliance date for the tune-up requirement in this rule has passed, but due to expected rule amendments EPA issued a No Action Assurance (NAA) letter valid through Dec 2012. The anticipated changes would extend the tune-up compliance date to March 21,2013. I reviewed the rule and the applicable requirements with Mr. Hinson. He is aware that a tune-up is required on both the boilers and that they must submit the required NOCS no later than 120 days later. They must also conduct a one-time energy assessment on the processes using steam produced by the boilers by March 21, 2014 and submit the required NOCS no later than 120 days later. These activities may be performed while operating on NG. A.15. 2D .1806,"Control and Prohibition of Odorous Emissions"—subject source is entire facility Appeared in Compliance — I detected no odors offsite when entering or departing the facility. No complaints have been received in the FRO DAQ or at the facility, according to Mr. Hinson. The facility has a process in place to record and address complaints as they are received. A.15. 2Q .0315,"Limitation to Avoid Title V" Appeared in Compliance — Records show weekly/monthly/annual inspections and maintenance for the bagfilters and cyclones. The records appear valid and complete. The facility has dried 40,000 tons of grain so far in CY 2012,well below the limit. FIVE YEAR COMPLIANCE HISTORY: 8 August 2011 —CAI for late reporting 112R APPLICABILITY: Based on visual observations and personnel interviews, this facility is subject only to the General Provisions of the 112r regulation. CONCLUSION/RECOMMENDATION Based on the observations made during the 7 November 2012 inspection, Murphy-Brown, LLC — Bladenboro Feed Mill appeared to be operating in compliance with the requirements outlined in their current air permit. /hsh
