Section II: INTRODUCTION

Summary of Permit Activity

Quapaw Products, LLC (Quapaw) operates a chemical manufacturing facility at 49 Phillips Road311 in Helena-West Helena, AR 72342. The site previously held a facility operating under thename of Cedar Chemicals, Permit # 878-AR-13.

Quapaw has requested permission to add a Urea Sulfate Production Process (SN-08), including abucket elevator and reactor T-I05.

Specific Condition #15 was added, to indicate that the permittee must also comply with the termsof the lease agreement with the Cedar Chemical Corporation Public Ownership Trust.

The emissions for the facility increased as follows, in tpy: +0.1 PM/PM IO•

Process Description

Quapaw Products, LLC (Quapaw) plans to manufacture chemicals in Helena-West Helena,Arkansas. Raw materials will be shipped to the site and transferred to storage tanks. Selectedraw materials will be delivered to the reactors, and generated products will be stored in tanksuntil distribution. All storage tanks have conservation vents to control emissions. Five productsare currently planned.

Alkyl Phosphites/Acid Phosphates Process

These products are manufactured in a process reactor that is a closed system with a condenserwhich recovers the vapor and sends it back to the process. The alkyl phosphates I acidphosphates unit has one closed reactor-condenser system. The emissions from the condenser arecollected with a vacuum pump and controlled by an acid scrubber (S-5201). The vent on thescrubber is the only emission point for this process, and methanol is the only pollutant that willbe emitted in this process.

Butanol Finishing Process

This product is manufactured in a process reactor that is a closed system with a condenser whichrecovers the vapor and sends it back to the process. The butanol finishing unit has one closedreactor-condenser system. The emissions from the condenser are collected with a vacuum pumpand controlled by an acid scrubber (S-520 1). The vent on the scrubber is the only emission pointfor this process, and butanol is the only pollutant that will be emitted in this process. All butanolprocess and storage equipment is subject to regulation under 40 CFR Part 60, Subpart VVa Standards of Performance for Equipment Leaks ofVOC in the Synthetic Organic ChemicalsManufacturing Industry.

Quapaw Products, LLCPermit #: 2189-AR-IAFIN: 54-00435

Acid Chloride Process

This product is manufactured in a process reactor that is a closed system with a filter andcondenser I still tame Filtered liquid which includes phosphorous acid and hydrochloric acid(HCI) will be stored in tank T-4206. Filtered vapor will be sent to a condenser I still tank systemto separate product and byproducts. Vapor from the condenser will be collected and treated witha caustic scrubber (C-4401) before discharge to the atmosphere. The vent on the scrubber is theonly emission point for this process, and hydrochloric acid is the only pollutant that will beemitted in this process. Emissions from this scrubber are based on a mass balance provided thatthe facility will not exceed a 7,000,000 lb/yr production of Octanoyl chloride.

BromMax Production

This product starts with mixing water and 50% sodium hydroxide in a single 4,000 gallon glassreactor. Then sulfamic acid crystal is added to the reactor while cooling. Next chlorine gas andliquid bromine are added using dip tubes. Chlorine introduced in the reactor is neutralizedimmediately and cannot exit as a gas in pH conditions greater than 3.8. Therefore, chlorine gaswill not become an air emission. Finally, 50% sodium hydroxide is added prior to qualitytesting. If the product meets specifications, water is added to make the product about a 7.1% Clzwith pH of 13.5. The reactor is a closed system so there are not any air emissions.

Liquid bromide is delivered into a single lead lined tank at 1,200 gallons per shipment. Duringthe filling from tanker truck to storage tank, a vapor recovery system routes displaced air fromthe receiving tank back into the tanker truck. Therefore, there will be no air emission. Thenliquid bromide is transferred to a 750 gallon day tank. During filling, emissions are controlledwith a 20% sodium hydroxide passive scrubber. Bromide is the air emissions becomes a sodiumbromide precipitate in the scrubber. No emissions are expected from this scrubber, but thisapplication assumes a minimal emission of 0.01 lb/hr.

Peracetic Acid Production

Peracetic acid production starts with mixing acetic acid and hydrogen peroxide in a 12,000gallon fiberglass insulated reactor. Then the content of the reactor becomes peracetic acid andwater. The product is stored in a tank until shipment. The emissions from the reactor andstorage tank are controlled with a passive scrubber. No emissions are expected from thisscrubber, but this application assumes a minimal emission of 0.01 lb/hr.

Urea Sulfate Production

The urea sulfate reaction is performed in multiple steps. First, a small amount (1Og) of sodiumthiosulfate is added to tank T-107, followed by water, and then urea. The urea is added viabucket elevator. The heat of solution for ureal water is endothermic, and the solution losestemperature.

Once the urea is in solution, two corrosion inhibitors are added to the mixture: copper sulfate anddiethylthiourea (DETU). Copper sulfate is added in small quantities with a scoop to the mix tank(24 lbl 130,482 lb batch) and DETU is added by pre-measured bags (l02 Ib/130,482 lb batch).Copper sulfate and DETU are added in small enough quantities that no emissions are expected.

Sulfuric acid is then slowly added over a 2-hour to 4-hour period, controlling the temperaturebetween 120 0 F and 160 0 F via side arm exchanger with chilled water to remove the heat ofdilution/reaction. The process duration is 8 to 10 hours per batch. All storage tanks, vessel, andcontainers related to this process are Group B insignificant activities; no emissions are expected.

(ii) A mixture of methane or n-hexane and air at a concentration no more than 2,000 ppm greaterthan the leak definition concentration of the equipment monitored. If the monitoring instrument's designallows for multiple calibration scales, then the lower scale shall be calibrated with a calibration gas that isno higher than 2,000 ppm above the concentration specified as a leak, and the highest scale shall becalibrated with a calibration gas that is approximately equal to 10,000 ppm. If only one scale on aninstrument will be used during monitoring, the owner or operator need not calibrate the scales that will notbe used during that day's monitoring.

(2) A calibration drift assessment shall be performed, at a minimum, at the end of each monitoringday. Check the instrument using the same calibration gas(es) that were used to calibrate the instrumentbefore use. Follow the procedures specified in Method 21 of appendix A-7 of this part, Section 10.1,except do not adjust the meter readout to correspond to the calibration gas value. Record the instrumentreading for each scale used as specified in § 60.486a(e)(7). Calculate the average algebraic differencebetween the three meter readings and the most recent calibration value. Divide this algebraic difference

Appendix A - 24

by the initial calibration value and multiply by 100 to express the calibration drift as a percentage. If anycalibration drift assessment shows a negative drift of more than 10 percent from the initial calibrationvalue, then all equipment monitored since the last calibration with instrument readings below theappropriate leak definition and above the leak definition multiplied by (100 minus the percent of negativedrift/divided by 100) must be re-monitored. If any calibration drift assessment shows a positive drift ofmore than 10 percent from the initial calibration value, then, at the owner/operator's discretion, allequipment since the last calibration with instrument readings above the appropriate leak definition andbelow the leak definition multiplied by (100 plus the percent of positive drift/divided by 100) may be remonitored.

(c) The owner or operator shall determine compliance with the no-detectable-emission standards in§§ 60.482-2a(e), 60.482-3a(i), 60.482-4a, 60.482-7a(f), and 60.482-10a(e) as follows:

(1) The requirements of paragraph (b) shall apply.

(2) Method 21 of appendix A-7 of this part shall be used to determine the background level. Allpotential leak interfaces shall be traversed as close to the interface as possible. The arithmetic differencebetween the maximum concentration indicated by the instrument and the background level is comparedwith 500 ppm for determining compliance.

(d) The owner or operator shall test each piece of equipment unless he demonstrates that a processunit is not in VOG service, i.e., that the VOG content would never be reasonably expected to exceed 10percent by weight. For purposes of this demonstration, the following methods and procedures shall beused:

(1) Procedures that conform to the general methods in ASTM E260-73, 91, or 96, E168-67, 77, or92, E169-63, 77, or 93 (incorporated by reference-see § 60.17) shall be used to determine the percentVOG content in the process fluid that is contained in or contacts a piece of equipment.

(2) Organic compounds that are considered by the Administrator to have negligible photochemicalreactivity may be excluded from the total quantity of organic compounds in determining the VOG contentof the process fluid.

(3) Engineering judgment may be used to estimate the VOG content, if a piece of equipment had notbeen shown previously to be in service. If the Administrator disagrees with the judgment, paragraphs(d)(1) and (2) of this section shall be used to resolve the disagreement.

(e) The owner or operator shall demonstrate that a piece of equipment is in light liquid service byshowing that all the following conditions apply:

(1) The vapor pressure of one or more of the organic components is greater than 0.3 kPa at 20 °G(1.2 in. H2 0 at 68 OF). Standard reference texts or ASTM 02879-83, 96, or 97 (incorporated byreference-see § 60.17) shall be used to determine the vapor pressures.

(2) The total concentration of the pure organic components having a vapor pressure greater than 0.3kPa at 20 °G (1.2 in. H2 0 at 68 OF) is equal to or greater than 20 percent by weight.

(6) ASTM 02382-76 or 88 or 04809-95 (incorporated by reference-see § 60.17) shall be used todetermine the net heat of combustion of component "i" if published values are not available or cannot becalculated.

(7) Method 2, 2A, 2C, or 20 of appendix A-7 of this part, as appropriate, shall be used to determinethe actual exit velocity of a flare. If needed, the unobstructed (free) cross-sectional area of the flare tipshall be used.

(h) The owner or operator shall determine compliance with § 60.483-1a or § 60.483-2a as follows:

(1) The percent of valves leaking shall be determined using the following equation:

Appendix A - 26
