6 Permit issued: October 11, Permit expires: January 23, 2018 Page 6 of Facility description The Elkay Wood Products Company - Waconia (Facility) is located at 180 Industrial Blvd in Waconia, Carver County, Minnesota. Elkay is a manufacturer of finished kitchen cabinets. The Facility assembles and finishes kitchen cabinet pieces purchased from outside sources or manufactured at the site based on customer design specifications. The cabinet pieces manufactured on site are refined from stock lumber by sawing, milling, and sanding to fit in the cabinets being assembled. The cabinet components are then loaded on a conveyer system which carries them through different stages of surface coating operations. The coatings applied are stains, lacquers and sealers. The product is then allowed to fan or oven dry followed by assembly, packaging, storage, and shipping. These changes include: addition of a cabinet finishing flatline process that will consist of two fully enclosed automated coating booths, two automated sanding units, a natural gas-fired boiler/water heater, a natural gas-fired air make-up unit. Reconfiguration of coating applied in the existing processing lines 1 through 3 and reconfiguration of the line 3 conveyor system. The Facility is proposing to modify the wood kitchen cabinet production process by adding a cabinet finishing flatline process. After this change, the Waconia facility would be classified as a major stationary source under prevention of significant deterioration for future permit actions. Removal of the existing UV line process from the Facility.

[Minn. R , subps. 4-5] Volatile Organic Compounds: [Stage 1] Accounting Period Calculations. The Permittee shall calculate VOC emissions using the following equations: VOC (tons/accounting period) = V - W V = ((A1 x D1x B1) + (A2 x D2 x B2) + (A3 x D3 x B3) +...))/2000 W = (C1 x F1) + (C2 x F2) + (C3 x F3) +... where: V = total VOC used in gallons/accounting period; A# = amount of each VOC-containing material used, in gallons/accounting period; D# = the density of A#, in lbs/gallon B# = weight percent VOC in A#, as a fraction; W = the amount of VOC shipped in waste, in tons/accounting period; C# = amount, in tons/accounting period, of each VOCcontaining waste material shipped. If the Permittee chooses to not take credit for waste shipments, this parameter would be zero; and F# = weight percent of VOC in C#, as a fraction. [Minn. R , subps. 4-5] Maximum Contents of Materials: The Permittee assumed certain worst-case contents of materials when determining the short term potential to emit of units in COMG 008. These assumptions are listed in Appendix C of this permit.

VOC, and Solids (PM, PM<10 microns, and PM<2.5 microns) contents in raw materials shall be determined by the Material Safety Data Sheet (MSDS) or CPDS provided by the supplier for each material used. If a material content range is given on the MSDS/CPDS, the highest number in the range shall be used in all compliance calculations. When using the MSDS as the basis of calculating particulate emissions, the conservative assumption is made that PM consists entirely of PM less than 10 microns or less than 2.5 microns. Other alternative methods approved by the MPCA may be used to determine the VOC, and solids

57 Technical Support Document For Air Emission Permit No This technical support document (TSD) is intended for all parties interested in the permit and to meet the requirements that have been set forth by the federal and state regulations (40 CFR 70.7(a)(5) and Minn. R , subp. 1). The purpose of this document is to provide the legal and factual justification for each applicable requirement or policy decision considered in the determination to issue the permit. 1. General information 1.1 Applicant and stationary source location: Table 1. Applicant and source address Applicant/Address Elkay Manufacturing Company 2222 Camden Court Oak Brook, IL Stationary source/address (SIC Code: 2434) Elkay Wood Products Company-Waconia 180 Industrial Blvd Waconia, Carver County, MN Contact: David Tax Phone: Facility description Elkay Wood Products Company- Waconia (Elkay) is a manufacturer of finished kitchen cabinets. The Facility assembles and finishes kitchen cabinet pieces purchased from outside sources or manufactured at the site based on customer design specifications. The cabinet pieces manufactured on site are refined from stock lumber by sawing, milling, and sanding to fit in the cabinets being assembled. The cabinet components are then loaded on a conveyer system which carries them through different stages of surface coating operations. The coatings applied are stains, lacquers and sealers. The product is then allowed to fan or oven dry followed by assembly, packaging, storage, and shipping. 1.3 Description of the activities allowed by this permit action This permit action is Major Amendment. The changes allowed in this permit action include the addition of a cabinet finishing flatline process that will consist of two fully enclosed automated coating booths, two automated sanding units, a natural gas-fired boiler/water heater, and a natural gas-fired air make-up unit. Elkay will also reconfigure the coating applied in the existing processing lines 1 through 3 and reconfigure the line 3 conveyor system, which will facilitate better product flow and timing for the curing process between coating applications. The existing UV line process will be removed from the Facility. After this change, the Facility would be classified as a major stationary source under Prevention of Significant Deterioration (PSD) for future permit actions. The MPCA has a combined operating and construction permitting program under Minn. R. ch. 7007, and under Minn. R Under that authority, this permit action authorizes construction.

59 Migrates the permit conditions into Tempo (the MPCA s new permitting database) from Delta (the previous database); In connection with past modifications and to fulfill Title V compliance requirements, the Waconia facility completed an ambient air quality compliance demonstration for particulate matter with an aerodynamic diameter of less than or equal to 10 microns (PM i0). As a result of that modeling, Air Emissions Permit No contains conditions requiring remodeling submittals and/or equivalent dispersion characteristics analyses in the event of proposed modifications to source parameters used in the previous compliance demonstration. Appendix D was updated to reflect the updated modeling. All processing lines will be limited to maximum operations of 20 hrs/day, except Line 1, which will be limited to 10 hrs/day. The primary reason for the limit on daily operations is to demonstrate compliance with the PM hour ambient air quality standard. All coating booth operations reflect changes to allowable coating types and as-applied coating solid content values to allow operational flexibility to meet customer demand and cabinet design. Updated PM 10 emissions performance test requirement for COMG 005. Based on the performance test results, the next performance test is due on or before 04/23/2019. New equipment associated with the automated cabinet finishing flatline process includes two total enclosure coating booths that each contain eight automated spray guns that may be operated simultaneously. Additional equipment includes two sanding units to provide finish sanding of cabinet components prior to coating. PM emissions from the sanding units would be controlled though connection to an existing woodworking baghouse (TREA 033). Each coating booth would be followed by a hot water curing/flash-off oven. The existing UV Line process will be removed from the Waconia Facility. The primary reason for removal of the UV Line will be to allow floor space to reconfigure the conveyor systems for Line 3 and allow existing coating booth (EQUI 096) to be relocated. The reconfiguration of the Line 3 conveyor system and booth relocation will facilitate better product flow and timing for the curing process between coating applications. Under existing COMG 002, the VOC pre-cap limits were removed from the permit. 2. Regulatory and/or statutory basis 2.1 New source review (NSR) VOC emissions from the existing coating operations, which was subject to pre-cap limits (COMG 002) will remain under the current permitted VOC emission limit of 240 tons per year, but the pre-cap limits were removed from the permit; therefore, the project will not result in any increase in emissions from the existing coating operations. The proposed addition of the cabinet finishing flatline would be subject to 225 tons per year of VOC emissions limit to avoid major source status under PSD. Under the PSD rules 40 CFR 52.21(b)(1)(b) and (c), a major stationary source is a stationary source that has the potential to emit 250 tons per year or more of a regulated pollutant, or any physical change at a stationary source that would constitute a major stationary source by itself, such as a resulting emission increase of greater than 250 tons per year. The Facility is allowed one-time bump under PSD; therefore, the Waconia Facility potential VOC emissions are less than 250 tons per year, an increase of 225 tons per year would not be subject to PSD preconstruction review. However, the Waconia Facility will be considered as a major stationary source under PSD for future permit actions with a total potential to emit of 465 tons of VOC per year. Any changes to the Facility will be subject to the significant emission rates (SER) thresholds for PSD review. 2.2 Part 70 permit program The facility is a major source under the Part 70 permit program. This permit action does not change the status of the facility. Technical Support Document, Permit Number: Page 3 of 10

60 2.3 New source performance standards (NSPS) The Permittee has stated that no New Source Performance Standards apply to the operations at this facility. 2.4 National emission standards for hazardous air pollutants (NESHAP) The facility is an existing major source of hazardous air pollutants (HAPs) and is subject to National Emission Standards for Wood Furniture Manufacturing Operations, 40 CFR pt. 63, subp. JJ. The additional of EQUI 204 and EQUI 205 are also subject to this NESHAP. Hot water would be provided by a small natural gas-fired boiler (EQUI 207) that is classified as a hot water heater and is therefore exempt from National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial and Institutional Boilers and Process Heaters, 40 CFR pt. 63, subp. DDDDD. 2.7 Compliance assurance monitoring (CAM) CAM applies to the following modification allowed in this permit action. Flatline 1 and Flatline 2 (EQUI 204 and EQUI 205) are subject to the requirements of CAM as emission units are other pollutant specific emission units (PSEU) for PM and PM 10. However, the Permittee is not required to submit the monitoring plan required under 40 CFR 64.4 at this time. A CAM submittal is required for a large PSEU under 40 CFR 64.5(a)(2) as part of an application for a significant permit revision under Part 70 or 71. CAM submittals are required for other PSEUs under 40 CFR 64.5(a)(2) as part of an application for the reissuance of a Part 70 permit. Therefore, CAM submittals for the emission units affected by this modification were not required to be submitted with the application. The Permittee is required to submit the monitoring plan required under 40 CFR 64.4 with their next application for permit renewal. 2.8 Environmental review and air emissions risk analysis (AERA) There are no changes authorized that would trigger the need for environmental review, i.e. an Environmental Assessment Worksheet (EAW), and is not required to perform an Air Emissions Risk Analysis (AERA). 2.9 Minnesota state rules Portions of the facility are subject to the following Minnesota Standards of Performance: Minn. R Standards of Performance of Control Equipment Minn. R Standards of Performance for New Indirect Heating Equipment Minn. R Standards of Performance for Post-1969 Industrial Process Equipment Table 6.

The language 'This is a state-only requirement and is not enforceable by the U.S. Environmental Protection Agency (EPA) Administrator and citizens under the Clean Air Act' refers to permit requirements that are established under state law rather than by the federal Clean Air Act. The language is to clarify the distinction between permit conditions that are required by federal law and those that are established under state law. State law requirements are not enforceable by the EPA or by citizens under the federal Clean Air Act, but are fully enforceable by the MPCA and citizens under provisions of state law. 3. Technical information 3.1 Calculations of potential to emit and emissions increase analysis Attachment 1 to this TSD contains the Title I net emissions increase calculations for this modification. This demonstrates that this modification by itself is not a major source for PSD. VOC and PM emissions for coating operations are based on mass balance considering the application rate of the material, transfer rate of the gun, capture efficiency of the paint booth filters and operating at maximum capacity, while limiting its hours of operations. In addition, the particulate emissions from the flateline will be controlled by a two-layers of panel filters in series, one providing 95 percent and one providing 98 percent for a total of 99.9 permit overall control. The control efficiency is based on Technical Support Document, Permit Number: Page 5 of 10

62 manufacturer equipment specifications in accordance with ASHRAE Method The combustion source potential emissions are calculated based on US EPA AP-42, chapter 1.4 for Natural Gas Combustion. Greenhouse calculations are based on 40 CFR pt. 98, Table A-Global Warming Potentials. 3.2 Dispersion modeling Per MPCA policy, as permitted in the original Part 70 permit, the facility triggered the requirement to complete air dispersion modeling to show modeled compliance with the PM 10 national ambient air quality standards (NAAQS) for the proposed modification. Several operating restrictions were assumed when the modeling was conducted, so these have been incorporated as permit limits such as hours of operation, solids content, and gun rates in the proposed major amendment permit. The following table presents a summary of the dispersion modeling results: Pollutant Year Modeled Impact (µg/m 3 ) Table 7. Dispersion Modeling Results Summary Background (µg/m 3 ) Total (µg/m 3 ) C NAAQS (µg/m 3 ) PM10 24-Hour A Annual A 24-Hour impacts are based on the highest-sixth-high concentration over five modeled years. B Annual impacts are based in the highest-first-high concentration of five modeled years. C All background sources and concentrations are included in the modeled results. In addition, per MPCA practice, a table of the modeled parameters has been added to the permit as Appendix. Other than the specific operating restrictions mentioned above, the parameters listed in Appendix D of the permit describe the operation of the facility at maximum capacity. In other words, the flow rates and temperatures listed in Appendix D represent the minimum parameters at the maximum emission rates. The MPCA does not require any specific compliance demonstration with these parameters because they are worsecase conditions. The purpose of listing the parameters in the permit appendix is to provide a benchmark for determining if and when additional modeling is required. The total ambient air impact of Elkay plus other sources and background is predicted to be micrograms per cubic meter (µg/m 3 ) for a 24-hour average and 47.7 µg/m 3 for annual average. This is greater than 90% of NAAQS. Based on MPCA practice for requiring modeling for future changes (see below), remodeling for PM 10 will follow Tier 3 requirements. Table 8.

63 CAM submittals for the emission units affected by this modification were not required to be submitted with the application. The Permittee is required to submit the monitoring plan required under 40 CFR 64.4 with their next application for permit renewal. In evaluating the monitoring included in the permit, the MPCA considered the following: The likelihood of the facility violating the applicable requirements. Whether add-on controls are necessary to meet the emission limits. The variability of emissions over time. The type of monitoring, process, maintenance, or control equipment data already available for the emission unit. The technical and economic feasibility of possible periodic monitoring methods. The kind of monitoring found on similar units elsewhere. The table 9 below summarizes the monitoring requirements associated with this amendment. Table 9. Monitoring Requirement Subject item* (rule basis) Monitoring Discussion NESHAP Sources: COMG 001 Various HAP requirements Compliance Equations and recordkeeping The Permittee will comply with the monitoring and operating procedures in 40 CFR pt. 63, subp. JJ to reduce HAP and VOC emissions from spraying/coating booths. The Permittee will continue to implement work practice plan and maintain good housekeeping practices as reference in Appendix B of the permit. Technical Support Document, Permit Number: Page 7 of 10

64 Subject item* COMG 008 (Flatline VOC & Coating Line) Requirement (rule basis) Monitoring Discussion VOC <= Recordkeeping: Daily tons per year, on records of coating a 12 accounting usage; On-going MSDS periods (limit to records of coating avoid major contents; Accounting source under period calculations of NSR) emissions. Records can be generated on a daily basis since all the coating materials are dispensed from the central area. This area will be using a combination of usage record of solvents based on purchase records (for smaller quantity items). The permit contains a limit of tpy of VOC with additional recordkeeping for VOC contents. Credit can be taken for waste materials collected and shipped off-site (dispensed - waste = emissions). Since this is done at most monthly, calculating emissions more frequently than monthly would result in large spikes (while waste is accumulating) and dips (when waste is shipped) resulting in possible paperwork violations and days with negative emissions. For these reasons, 12-month accounting periods are reasonable for this Facility. Accounting period tracking system is used by the Facility, which is based on weeks rather calendar months. There are always 12 accounting periods per year, but the number of weeks in each period is not always the same for each year. This is determined prior to the start of the year and is used throughout the year for all business functions. Since this varies from year to year, the permit requires the Permittee to include the defined accounting periods for the following year in each Annual report. EQUI 206 and EQUI 207 (Added to COMG 004, Indirect Heating Equipment) EQUI 208 and EUQI 209 (Added to COMG 005 Wood Working Equipment) PM: <= 0.40 lb/mmbtu; Opacity: 20 % with exceptions (Minn. R ) PM: <= gr/dscf (limit to avoid NSR and NAAQS) Opacity: 20 % (Minn. R. Recordkeeping: Monthly Fuel records Performance testing for PM10 Control equipment monitoring The Permittee will continue to differentiate between the VOC limits under COMG 002, which is now a cap limit and under COMG 008. All units use natural gas; therefore, the likelihood of violating either of the emission limits is very small. The Permittee can demonstrate that these units will continue to operate such that emissions are well below the emission limits by only burning natural gas. Since this is a permit condition, the semi-annual deviations report will document any deviations from this condition. Design based PTE for each unit, using AP-42, is compared to the rule limit of 0.40 lb/mmbtu. Based on existing performance test results, the Facility will continue to utilize their current performance test frequency of once every 3 years. The next performance test is scheduled for 04/24/2019. Technical Support Document, Permit Number: Page 8 of 10

TREA 041 must control EQUI 204 and TREA 042 must control EQUI 205. The particulate emissions from the flateline are controlled by a two-layers of filters in series, one providing 95 percent and one providing 98 percent for a total of ((1-0.95)(1-0.98) = 0.001, which is a 99.9 percentage overall control. Elkay Wood Products has several operations which are classified as insignificant activities under the MPCA s permitting rules. These are listed in Appendix A to the permit. This permit action does not authorize new insignificant activities or any change to the existing insignificant activities. The Technical Support Document for Permit No includes a discussion of periodic monitoring for the existing insignificant activities. 3.5 Permit organization In general, the permit meets the MPCA Tempo Guidance for ordering and grouping of requirements. One area where this permit deviates slightly from Tempo guidance is in the use of appendices. While appendices are fully enforceable parts of the permit, in general, any requirement that the MPCA thinks should be electronically tracked (e.g., limits, submittals, etc.), should be in the Requirements table in Tempo. The main reason is that the appendices are word processing sections and are not part of the electronic tracking system. Violation of the appendices can be enforced, but the computer system will not automatically generate the necessary enforcement notices or documents. Staff must generate these. This permit uses an appendix for specific procedures from 40 CFR pt. 60, subp. JJ. These procedures are too complex to enter into Tempo and must go in an appendix. Another area that deviates from the guidance is in the use of groups where the requirements in the group apply to the members of the group individually. This was done in order to shorten the permit and where no testing or tracking specific to a unit is in the permit (thereby reducing the likelihood that there will be further unit-specific requirements later). This is the case for the requirements at COMG 008 (VOC and Coating limits) and COMG 009 (modeling limits). Technical Support Document, Permit Number: Page 9 of 10

66 3.6 Comments received The MPCA plans to issue this proposed permit under the provisions of Minn. R , subp. 7. This rule allows the MPCA to issue permits in two stages. The requirements issued in the first stage - the Stage 1 conditions - are the portions of the proposed permit that relate to the construction activities authorized by the proposed permit. Stage 1 conditions include emissions limits, restrictions on hours of operation and the recordkeeping associated with that restriction, and requirements to demonstrate initial compliance. In this proposed permit, many Stage 1 conditions are identified as Title I Conditions to avoid classification as a major source and can be found in the TSD, section 1.6, which describe the authorized to construct. Stage 1 conditions are denoted in the permit by [Stage 1]. No comments were received during the 30-day public comment period; therefore, the issuance of Stage 1 conditions is authorized under Minn. R , subp. 7(A)(2). No comments were received during EPA 45-day comment period. Public Notice Period: September 9, 2016 October 10, 2016 EPA Review Period: September 9, October 25, Permit fee assessment Attachment 4 to this TSD contains the MPCA s assessment of Application and Additional Points used to determine the permit application fee for this permit action as required by Minn. R The permit action includes one permit application, which was received after the effective date of the rule (July 1, 2009). The action includes the incorporation of a NESHAP, however this was an existing standard that applied to the facility and is not a chargeable activity. The chargeable activities are modeling review (15 pts.) and limits to avoid major status under NSR/PSD (10 pts). 5. Conclusion Based on the information provided by Elkay Wood Products the MPCA has reasonable assurance that the proposed operation of the emission facility, as described in the Air Emission Permit No and this TSD, will not cause or contribute to a violation of applicable federal regulations and Minnesota Rules.

68 Paint Booth Calculation Methodology Step 1: Information is obtained from the finishing department (and coating supplier recommendations) regarding the appropriate spray gun tip size and fluid pressure for each specific coating type. This information is presented as orifice size (in.) and fluid pressure (psi) on each individual emission unit calculation worksheet. Example: EU100, White Primer, has a required orifice of in. and a fluid pressure of 650 psi. Step 2: Spray gun capacity information from the "GunCap" worksheet is used to develop the maximum application rate for the specific product type. The spray gun capacity information based on manufacturer provided performance data for various orifice sizes and fluid pressures. Example: A tip size of in. and a fluid pressure of 650 psi results in a corresponding application rate of gal/hr. Step 3: If the applied coating product is a mixture, the mix percentage is used to adjust the flow rates for individual product constituents. If there are no additives, the coating product mix percentage is 100%. Example: White Primer is applied as mixture of 94% primer and 6% catalyst. The calculated spray gun capacity is gal/hr. Therefore, the white primer portion is (10.39)(0.94) = 9.77 gal/hr. the catalyst portion is (10.39)(0.06) = 0.62 gal/hr. The total as applied mixture is = gal/hr. Step 4: Steps 1 through 3 are repeated for each product type and spray booth. Step 5: For each product type, the application rate and material specific content are used to develop VOC, PM10 and HAP emission rates. Example: White Primer is applied at 9.77 gal/hr. Based on manufacturer data the density is lb/gal, the VOC content is 37.95%, and the solids content is 58.63%. Therefore, the resulting VOC emissions are (9.77 gal/hr)(10.25 lb/gal)(0.3795) = lb/hr. The uncontrolled PM10 emission rate is (9.77 gal/hr)(10.25 lb/gal)(0.5863) = lb/hr. However, the uncontrolled PM10 emission rate must be adjusted by both the transfer efficiency of the spray gun (75%) and the collection efficiency of the panel filter system (97.1%). Therefore the final controlled PM10 emission rate is (58.71)(1-0.75)( ) = 0.43 lb/hr. HAP emissions are calculated in the same way as VOC emissions. Note: Based on requirements in the Waconia facility operating permit to maintain closed doors and air curtain operations, the entire facility is considered a total enclosure. Therefore, 100% capture is maintained for each spray booth. Step 6: For each spray booth type, the worst case coating material based on application rate and VOC, PM and HAP content is chosen as the representative coating. It is possible that the worst case values for VOC, PM and HAP may be from different coatings products. Therefore, a worst-case hybrid coating is represented for PTE purposes. Additionally, it is assumed that each coating material is applied at maximum spray gun capacity 24 hours per day and 8,760 hours per year. It is assumed that 2 spray guns per booth may be used simultaneously. The flat line booths can use a maximum of 8 spray guns simultaneously. Example: The as applied White Primer/Catalyst mixture has combined VOC emissions of 42.0 lb/hr. 9/6/2016 Page 2 of 144 Waconia Emission Calcs_09_06_16 Update.xls

69 Compared to the individually applied stains in EU100, the next highest VOC material is Amaretto Soft Touch Spray at lb/hr. Therefore, it is assumed that the White Primer/Catalyst mixture is applied full-time in EU100 for the purpose of VOC emissions. Each subsequent pollutant is evaluated in the same manner. Step 7: To provide operational flexibility, final PM10 limits in the permit are based on the maximum amount of solids in a coating that can be applied in a given hour. This is directly related to the calculated PM10 emission rate used in the modeling compliance demonstration. Example: For EU100, the worst case coating for PM10 was the White Primer/Catalyst mixture. The PM10 controlled emission rate was 0.43 lb/hr. By looking at the coating characteristics for the mixture, the actual solids content (as applied) is (9.77 gal/hr)(10.25 lb/gal)(0.5863) + (0.62 gal/hr)(7.79 lb/gal)(0.1759) = lb/hr. Therefore the maximum coating solids content that can be applied in EU100 is lb/hr, as applied, for each spray gun. To verify this value the transfer efficiency of 75% and control efficiency of 97.1% can be applied: (59.56)(1-0.75)( ) = 0.43 lb/hr. Note: VOC emissions are limited and tracked based on product purchase/usage. Therefore, it is not necessary to calculate booth specific emission limits. Furthermore, VOC emissions are not limited on a short-term hourly basis. HAP emissions are secondarily limited by the VOC emission limit. 9/6/2016 Page 3 of 144 Waconia Emission Calcs_09_06_16 Update.xls
