Section II: INTRODUCTION

Summary ofPermit Activity

Riceland Foods - Stuttgart Rice Div. (AFIN 01-00005) is located at 1st Street and College,Stuttgart, Arkansas 72160. The operations include the receiving, cleaning, drying, storage, andshipping of rice. In this modification, Riceland seeks to remove an existing 40 year old Clippergrain dryer (SN-14) at the Drier 3 green rice receiving unit and replace it with a Shanzer graindryer Mode14R5 (SN-120) rated at 4000 bushels/hour and 11.6MM Btu/hr. This modificationalone will increase permitted emissions as follows: PM, 0.9 tpy; PMlO 0.6 tpy; NOx, 4.2 tpy;VOC, 0.2 tpy, and CO, 4.2 tpy. In the application review process, some errors were discoveredin the permitted emission totals for the active permit, #0489-AR-13. Actual PM totals from theindividual sources in R-13 are 269.1 tpyas compared to 270.9 tpy permitted. Actual PMlO totalsfrom R-13 sources are 88.9 tpy as compared to 69.8 tpypermitted. Actual VOC totals from R-13sources are 4.7 tpy as compared to 25.2 tpy permitted. When accounting for these differencesand the impact of the modification, total permitted emissions change as follows with thisapplication: Permitted PM decreases by 0.9 tpy, permitted PMlO increases y 19.7 tpy, permittedVOC decreases by 21 tpy, and permitted CO and NOx increase by 4.2 tpy each.

Process Description

Section F

Section F is responsible for receiving and storing dry rough rice from outlying dryer locationsand white and brown rice from Mills B and C. The building to the East is referred to as OldSection F and the building to the West is referred to as New Section F.

Rough rice is received into Section F by two (2) truck dumps and two (2) rail dumps. White andbrown rice is received from Mills B and C via an overhead conveyor belt. The rice is moved bybucket elevators to belt conveyors on the tripper floors over the storage bins. Trippermechanisms transfer the rice from the belts to the bins.

Two bulk scales located in the head house of Old Section F are used to batch weigh rice as itdischarges from the elevators. A Kice aspirator is also located in Old Section F and isoccasionally used to pull trash from the rough rice before it is stored.

Rice is removed from the bins by the basement belt conveyors which discharge into threeelevators. The rough rice can then be transferred directly to Mill B and Mill C, to the ParboilPlant, or Association Storage. Rough, white, and brown rice can be shipped out by truck orrailcar.

5


Association Storage

Association storage functions as a receiving and holding area for rough rice going into Mills Band C. Rice is conveyed to Association Storage from Section F, Dryer 2, and Dryer 3 anddischarged into receiving bins. It is moved by the basement belt conveyor and bucket elevatorsto the tripper floor belt into storage. Two bulk scales are located in the head house for batchweighing of rice.

Rice can be moved from storage to Mill B by drag conveyors in the basement. Mill C is suppliedby a screw conveyor which is fed by storage bins on the South end of the building.

MillsB and C

Mills Band C process rough rice received from Section F or Association Storage into white orbrown rice for packaging or bulk shipment. The milling process is essentially the same in bothmills. Rough rice is weighed in batch scales as it enters the mills. It is cleaned by scalpers, stickmachines, and aspirators to remove trash, hulls and other foreign material. The cleaned ricepasses through shellers which remove and separate out most of the hulls from the rice. Theshelled rice, referred to as brown rice, continues through monitors which separate out anyremaining loose hulls. Hulls removed by the shellers and monitors are blown to the By-ProductsPlant for processing. The brown rice is passed through paddy machines which separate out anyrice still in the hull and return it to the shellers.

For white rice production, the brown rice is fed through the mist milling machines which removethe bran layer by abrasion. Lime can be added at the pearlers to increase the abrasion. Most ofthe removed bran is separated from the rice by aspiration in the pearlers. Any remaining loosebran is removed from the white rice by the clean rice aspirators.

For brown rice production, the rice is sent directly from the paddy machines to the clean riceaspirators to remove and loose bran. The bran from the pearlers and aspirators is collected bycyclones and bag filters, cleaned, and blown to By-Products for processing.

After aspiration, the white or brown rice passes through a grading process. Disc graders,precision graders, and Rotex machines are used to separate the rice based on the degree ofbrokenness, into fancy, head, or brewers. The graded rice is then sent to the PackagingDepartment or to Clean Rice Shipping.

Clean Rice Shipping

Clean rice shipping receives white rice and brown rice from Mills Band C. The rice can bestored, transferred to Section F or the packaging department, or shipped out by truck or railcar.

Parboil Plant

The parboil process is used to partially cook rough rice while it is still in the hull. This canincrease the milling yield of lower quality rice.

Rough rice is received at the Parboil Plant by bins at the East end of Old Section F. The rice iscleaned by a scalper, stick machines, and aspirators and then graded by disc and precisiongraders. It is conveyed to the soak tanks where it is held to allow hot water to be absorbed by thegrains. The soaked rice then passes through the cooker where it is partially cooked by steam.

6


After cooking, the rice is pneumatically sent through a Link-belt rotary dryer, a CCF dryer andfinal bin aeration. Ifneeded, the rice can be sent from the Link-belt dryer to surge bins beforecontinuing through the Westelaken dryer. The Shanzer column dryer is placed in series behindthe Westelaken dryer to make the parboil drying a three stage process through the dryingprocess.

After drying and aeration, the rice is sent to the Parboil Mill for processing.

Parboil Mill

The milling process at the Parboil Mill is basically the same as that in Mills Band C. The maindifferences are that the parboiled rough rice is not aspirated, since most loose trash has beenremoved by the parboiling process and that there are no monitors between the shellers and paddymachines.

Parboiled rough rice enters the mill from the Parboil Plant's aeration bins at the East end of OldSection F, passes through the milling process, and is sent to the mill's aeration bins in Section F.

The milled rice is sent through the Parboil Sortex Department and is then either shipped out atParboil Shipping or sent to the main Packing Department.

Parboil Sortex

The Parboil Sortex Department is responsible for sorting out grains of milled parboiled ricewhich were discolored by the parboiling process.

The rice is aspirated as it enters the Sortex to remove loose bran and dust. A destoner aspirator isalso used to clean the rice. One of the last processes prior to storage of the rice is color sorting.The color sorters, Sortex machi~es, remove the stained and discolored rice kernels.

The Sortex machines process both white and brown parboiled rice. When processing brown rice,the sorters tend to loosen some of the bran creating a small amount of dust within the sorter. Thebran is very sticky and creates a film on the sorter camera and creates a buildup on the airnozzles, thus affecting the sorters efficiency. An aspiration dust system has been added to thesorting process. The dust system is comprised of an Environmental Pneumatics bag filter modelEP-PJ-120-208-120 with 2496 sq. ft. of filter media and a 60 hp Phelps fan providing an air flowof 10,000 cfm. To decrease heating and cooling cost of the sorter area, the air from the bag filteris nonnally discharged back into the mill. There is a flow diverter that allows air to be dischargedoutside the mill under certain emergency situations. For example, in the event of a fire in thefilter or if the filter stopped up the air could be diverted outside the building.

From Sortex, the rice is sent to Parboil Shipping or to the Packing Department.

By-Products Plant

The By-Products Plant receives the material collected by the dust control systems in the RiceProcessing Division and produces saleable items from it. The three (3) by-products of riceprocessing are hulls, bran, and a material referred to as chicken feed. The chicken feed consistsof seeds, straw, hull particles, and other foreign material found in rough rice. The itemsproduced from these by-products are bulk and packaged hulls, bulk and pelletized bran, andpelletized feed.

7


The by-products are blown from the mills via pneumatic lines and are received by bag filters atthe By-Products Plant. The hulls are cleaned and can be stored whole for bulk and packageshipment, or ground by the hammer mills and blown to the pellet mill. The bran is cleaned andstored for bulk shipment or blown to the pellet mill. The chicken feed is ground and blown tothe pellet mill.

The bran and the ground hulls and chicken feed are mixed at the pellet mill to produce feedpellets. The bran can also be pelletized alone. Moist steam from the mill boiler is used to bindthe ground products together to fonn pellets. Pellet coolers are used to lower the temperature ofthe pellets before storage.

Bran Stabilization

The Bran Stabilization Plant receives raw material from the rice milling operations and preparesor stabilizes it for the oil extraction process. The bran is pneumatically conveyed from the ricemill to the bran receiving tank. At this point in the process, the bran is in a powder fonn. Tocontrol the dust produced by the bran entering the tank, a bin vent filter will be used to vent thetank.

The bin vent filter utilizes fabric bags to control emissions. The bran discharges from thereceiving tank onto screw conveyors and is transferred to the bran expander. At the expander,steam is added and the bran is fonned into pellets.

A boiler unit provides steam required by the expander. The boiler emits natural gas combustionproducts. The bran pellets leaving the expander process are conveyed by a belt conveyor to thedryer/coolers. The pellets will be dried, cooled, and transferred to a storage bin. Thedryer/cooler will be vented to the atmosphere and will emit water vapor and bran dust. A highefficiency cyclone will be used to control dust emissions from the dryer/cooler.

From the dryer/cooler, the pellets are stored in the stabilized bran bin. Again, a bin vent filterwill be used to control dust emissions from the storage bin.

Rice Hull Converter

This process consists of a rice hull receiving bin, a rotary combustor, a hull ash receiving bin, anafterburner, and packaging equipment for the ash product.

Rice hulls are pneumatically conveyed from the rice mill to a hull receiving bin. The bin will bevented to atmosphere through a fabric bin vent filter. The hulls will then be continuouslymetered to the combustion unit.

Prior to hulls entering the combustion unit, it will go through a brief start-up period using naturalgas. The natural gas burners will be ignited and the combustor allowed to come up totemperature. It takes approximately 30 minutes at a heat input rate of 18 MMBtu/hr for thecombustor to reach the desired temperature. Once this occurs, the rice hulls are then fed into thecombustion unit, along with air. The burners remain lit for a period of about 15 minutesfollowing the injection of the hulls to allow the hulls to be properly ignited. Once ignited, thegas burners are turned off and the process relies on the proper air to hull mixture to sustaincombustion within the unit. The combustion unit produces silica ash and gases.

8


The produced ash is then blown from the point it exits the combustor to an ash receiving bin.The ash receiving bin will be vented to atmosphere through a fabric bin vent filter. The ash willbe held in the receiving bin for packaging.

Section III: PERMIT HISTORY

Permit 489-A was the initial pennit for the facility and was issued on April 28, 1978.

Permit 489-AR-l was issued on March 23, 1983.

Permit 489-AR-2 was issued on July 3, 1986.

Permit 489-AR-3 was issued on December 29, 1986. This modification pennitted thereplacement of old inefficient equipment in order to reduce particulate emissions.

Permit 489-AR-4 was issued on May 21, 1991. This modification incorporated all "NSPSapplicability" into the pennit, as well as, consolidated several other Riceland pennits.

Permit 489-AR-5 was issued on June 11,1992. This modification further consolidated existingRiceland pennits. This modification also pennitted two additional bag houses and cyclones aswell as an additional dryer.

Permit 489-AR-6 was issued on October 8, 1993.

Permit 489-AR-7 was issued on February 23, 1994. This modification pennitted a rice hullconverter plant to be operated at the Stuttgart facility.

Permit 489-AR-8 was issued on May 16, 1997. The pennit was modified to reflect themodification to the By-Products Loadout facility (SN-l 00). Inspection revealed that the By-Products Loadout facility exceeded opacity limits. This pennit also reflected new emissionfactors and methods ofcalculation based on the Grain Handling and Grain Processing EmissionFactors from AP-42, chapter 9. Source numbers were not the same as those for R7.

Permit 489-AR-9 was issued on November 20, 1997. This permit was the collective result ofseven pennit applications. For expediency and accuracy rather than issuing seven individualpennits resulting from the applications, the Department decided to combine the applications intoone pennit. The following changes implemented by these pennits did not increase the pennittedlimits ofgrain throughput:

22 January 1998 (Pennit 489-AR-9 continued)

Thirty-six pearlers were replaced with eighteen friction and eight abrasive mills. Anadditional bran receiver bag filter (SN-I05) was added which relayed captured bran backto bag filter SN-33.

7 August 1998 (Pennit 489-AR-9 continued)

Six dust control cyclones (SN-34, SN-35, SN-50, SN-38, SN-39, and SN-43) werereplaced with two bag filters (SN-l 06, SN-I07) at the facility's Mill C.

10


5 January 1999 (Permit 489-AR-9 continued)

The existing peading system was replaced with mist milling and an additional bag filter(SN-108).

An additional 1.95 million bushels of flat storage was added to the Drier 3 complexresulting in a receiving pit (SN-109) and drying fans (SN-11O).

Removed cyclones used on the clean rice stream-(SN-36, SN-37, SN-40, SN-41,SN-42, SN-46, SN-47, SN-48, SN-49).

2 December 1999 (Permit 489-AR-9 continued)

A 6 MMBtu/hr Dryer was replaced with a 9 MMBtu/hr horizontal belt dryer, requiringmodification of SN-82 and an additional cyclone SN-111 for the new dryers coolingsection.

26 April 2000 (permit 489-AR-9 continued)

Added a new nuisance dust collector SN-112 and removed cyclones SN-44 and SN-45.

12 May 2000 (Permit 489-AR-9 continued)

Added a milling system to the facility's Parboil Mill Complex and converted dustcollectors SN-75 and SN-76 to nuisance dust collectors. Added three new dustcollectors.

Permit 489-AR-I0 was issued August 2, 2001.Riceiand Foods modified the Parboil Plant byinstalling a new third stage column dryer (SN-115). Parboil rice had dried in two (2) stages. Thefirst drying stage occurred in a Link-Belt rotary dryer located within the parboil plant. Thesecond stage took place in a Westelaken column dryer located outside the facility. The newShanzer dryer was located in series adjacent to the Westelaken for a third drying stage. TheShanzer dryer is a Model 6G6, with a drying capacity of approximately 3000 bushels per hour.The Shanzer dryer has a warm air burner rated at 18.2 MMBtu/hr and a cooling section burnerrated at 10.9 MMBtu/hr. Particulate generated by the new dryer is controlled by 24 mesh screenson the dryer enclosure louvers. This application also includes a new calculation and rate tablefor the SN-109, Flat Storage Receiving Pit. The pit was permitted at a receiving rate of 15,000bu/hr (total bu/yr remains unchanged). Testing demonstrated that the pit can only receive at arate of about 7500 bu/hr.

Permit 489-AR-ll was issued August 6,2003. The permit combined the permit applicationsubmitted January 23,2003, with the permit application submitted February 13, 2003. Thepermit allowed:

• The installation of two bag houses (SN-116 and 117) to replace a single bughouse(SN-08). The Drier #2 Nuisance Dust, included additional pickup points, is handledby SN-116 and SN-117.

• The replacement of four cyclones (sources 54, 55, 56, and 57) with a bughouse. Thebughouse retained SN-57. Emissions showed an increase because ofan increasedwhite rice product. Total tons of grain processed per year did not increase.

11


Permit 489-AR-12 was issued March 18, 2004 and allowed:

In this pennit an aspiration system for the sorting process was installed (SN-118). SN-118increased PM emissions by 0.9 tons per year.

The aspiration system is comprised of an Environmental Pneumatics bag filter model EP-PJ-120-208-120 with 2,496 square feet offilter media and a 60 hp Phelps fan (air flow of 10,000 cfm).The air from the bag filter is discharged back into the mill to decrease heating and cooling cost ofthe sorter area. A flow diverter allows air to be discharged outside the mill under emergencysituations (a fire in the filter or if the filter is stopped-up).

Permit 489-AR-13 was issued on April 17, 2006. Riceland added a separate bran collectionsystem (bag filter) to the VBF 3rd break milling machines. This increased pennitted emissionsby 3.1 tons/yr PM and 1.8 tons/yr PM IO• The addition of the bag filter (SN-119) did not increaseproduction. Emissions from the break milling machines are distributed between 3 bag filters(revised from 2 bag filters). Emissions from the existing filters (SN-l13 and SN-114) remainunchanged resulting in a pennitted increase with the addition of the new bag filter. In addition,Riceland replaced the current BS Steam Boiler (SN-84) with a new Superior Boiler Work 400 hpboiler and an 8" Anderson expander with a 10" Anderson Expander. These changes result inpennitted emission increases of 7.6 tons/year PM, 1.3 tons/yr PM IO, and 6.2 tons/yr NOx

(b) Except as provided in paragraphs(c) and (e) of this section, on and afterthe date on which the performance testis completed or required to be com-pleted under §60.8, whichever datecomes first, the owner or operator ofan affected facility that:

(1) Combusts only coal refuse alonein a fluidized bed combustion steamgenerating unit shall neither:

(1) Cause to be discharged into the at-mosphere from that affected facilityany gases that contain 802 in excess of87 ng/J (0.20 IbIMMBtu) heat input or 20percent (0.20) of the potential 802 emis-sion rate (80 percent reduction); nor

(11) Cause to be discharged into theatmosphere from that affected facilityany gases that contain 802 in excess of802 in excess of 520 ng/J (1.2 IbIMMBtu)heat input. If coal is fired with coalrefuse, the affected facility subject toparagraph (a) of this section. If oil orany other fuel (except coal) is firedwith coal refuse, the affected facility issubject to the 87 ng/J (0.20 IbIMMBtu)heat input 802 emissions limit or the90 percent 802 reduction requirementspecified in paragraph (a) of this sec-tion and the emission limit is deter-mined pursuant to paragraph (e)(2) ofthis section.

(2) Combusts only coal and that usesan emerging technology for the controlof 802 emissions shall neither:

(i) Cause to be discharged into the at-mosphere from that affected facilityany gases that contain 802 in excess of50 percent (0.50) of the potential 802emission rate (50 percent reduction);nor

(11) Cause to be discharged into theatmosphere from that affected facilityany gases that contain 802 in excess of260 ng/J (0.60 lblMMBtu) heat input. Ifcoal is combusted with other fuels, theaffected facility is subject to the 50percent 802 reduction requirementspecified in this paragraph and the

§60.42c

emission limit determined pursuant toparagraph (e)(2) of this section.

(c) On and after the date on whichthe initial performance test is com-pleted or required to be completedunder §60.8, whichever date comes first,no owner or operator of an affected fa-cility that combusts coal, alone or incombination with any other fuel, and islisted in paragraphs (c)(l), (2), (3), or (4)of this section shall cause to be dis-charged into the atmosphere from thataffected facility any gases that contain802 in excess of the emission limit de-termined pursuant to paragraph (e)(2)of this section. Percent reduction re-quirements are not applicable to af-fected facilities under paragraphs(c)(l), (2), (3), or (4).

(1) Affected facilities that have aheat input capacity of 22 MW (75MMBtulhr) or less.

(2) Affected facilities that have anannual capacity for coal of 55 percent(0.55) or less and are subject to a feder-ally enforceable requirement limitingoperation of the affected facility to anannual capacity factor for coal of 55percent (0.55) or less.

(3) Affected facilities located in anoncontinental area.

(4) Affected facilities that combustcoal in a duct burner as part of a com-bined cycle system where 30 percent(0.30) or less of the heat entering thesteam generating unit is from combus-tion of coal in the duct burner and 70percent (0.70) or more of the heat enter-ing the steam generating unit is fromexhaust gases entering the duct burner.

(d) On and after the date on whichthe initial performance test is com-pleted or required to be completedunder §60.8, whichever date comes first,no owner or operator of an affected fa-cility that combusts oil shall cause tobe discharged into the atmospherefrom that affected facility any gasesthat contain 802 in excess of 215 ng/J(0.50 IbIMMBtu) heat input; or, as an al-ternative, no owner or operator of anaffected facility that combusts oilshall combust oil in the affected facil-ity that contains greater than 0.5weight percent sulfur.
