1 Technical Support Document for Draft Air Emission Permit No This technical support document (TSD) is intended for all parties interested in the draft 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 preliminary determination to issue the draft permit. 1. General information 1.1 Applicant and stationary source location Table 1. Applicant and source address Applicant/Address New Flyer Industries Inc 711 Kernaghan Ave Winnipeg, Canada R2C 3 T4 Contact: Dan Metoyer Phone: Stationary source/address (SIC Code: 3711 Motor Vehicles and Passenger Car Bodies) New Flyer of America Inc Saint Cloud 6200 Glenn Carlson Dr Saint Cloud, MN Facility description New Flyer operates a bus manufacturing facility in St. Cloud, Minnesota. The plant currently consists of two manufacturing lines capable of producing 6 complete buses each day. The main sources of emissions are coating operations controlled by panel filters, emissions from natural gas combustion used in curing coatings, and an emergency generator. The facility also has several operations that qualify as insignificant activities. See Section 3.4 of the TSD for more information. This permit carries forward requirements that limit the emissions of volatile organic compounds (VOC), hazardous air pollutants (HAPs), and particulate matter/particulate matter less than 10 microns/particulate matter less than 2.5 microns (PM/PM10/PM2.5). The permit also contains requirements to control particulate from the various spray booths. 1.3 Description of the activities allowed by this permit action This permit action is a Part 70 Reissuance. 1.4 Description of notifications and applications included in this action Table 2.

Table 4. Facility classification Classification Major Synthetic minor/area Minor/Area New Source Review X Part 70 X Part 63 X 1.6 Changes to permit The permit does not authorize any specific modifications, however, the MPCA has a combined operating and construction permitting program under Minnesota Rules Chapter 7007, and under Minn. R , the MPCA has authority to include additional requirements in a permit. Under that authority, the following changes to the permit are also made through this permit action: All HAPs The permit has been updated to reflect current MPCA templates and standard citation formatting. Completed requirements and the requirements for equipment that has been removed have been deleted. TREA 8 was added into the permit under the no CAM panel filter group (COMG 4). This panel filter was not in the last permit action due to an error on the MPCA s behalf. The panel filter control efficiencies have been changed from 92% to 85% based on current industry knowledge. The Coach Engine Testing Cells have been removed from the insignificant activity appendix per guidance in the November EPA letter to Michigan DEQ re: General Motors Orion Assembly Facility. This letter is Attachment 5 to this TSD. At the time of testing, the bus is ready for introduction into commerce and the testing is checking for the vehicle s readiness for transportation. The emissions resulting directly from internal combustion engines are for transportation purposes within the meaning of Section 302(z) of the Clean Air Act. Therefore, the engines in the buses are not subject to stationary source requirements. 2. Regulatory and/or statutory basis 2.1 New source review (NSR) The permit carries forward limits on the facility such that it is a minor source under New Source Review regulations. No changes are authorized by this permit. 2.2 Part 70 permit program The facility is a major source under the Part 70 permit program. Technical Support Document, Permit Number: Page 2 of 10

3 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 has accepted limits on HAP emissions such that it is an area source under 40 CFR pt. 63. Thus, no major source NESHAPs apply. The Permittee provided their determination of why 40 CFR pt. 63, subs. XXXXXX and HHHHHH do not apply to the facility. These subparts are NESHAP Area Source Standards for (1) Nine Metal Fabrication and Finishing Source Categories and (2) Paint Stripping and Miscellaneous Surface Coating Operations at Area Sources, respectively. See Attachment 4 of this TSD for copies of that information. 2.5 Compliance assurance monitoring (CAM) The table below lists the sources subject to CAM, the control equipment used, whether the source is a large or other pollutant specific emission unit (PSEU), and the pollutants triggering CAM. Specific monitoring requirements are discussed in Table 7 of this TSD. Table 5. CAM summary Unit Control CAM applicability Pollutant EQUI 9 and TREA 3 Panel Filter Other PM EQUI 11 TREA 6 Panel Filter See Attachment 3 to this document for the CAM Plan submitted by the applicant. The calculations for this permit action reflect that EQUI 9 and EQUI 11 are not subject to CAM. However, after discussing with the Permittee, the Permittee decided to keep CAM in the permit to allow for future flexibility in the materials used. Note: the Permittee incorrectly identified that CAM applied to additional painting operations (EQUIs 12, 13, 14), but according to MPCA calculations, these paint booths do not need the control equipment to comply with an emissions limit (one of the criteria to be subject to CAM) and are therefore not subject to CAM. 2.6 Environmental review and air emissions risk analysis (AERA) No modifications or emissions increases are authorized by this permit action, so the permit is not subject to environmental review. 2.7 Minnesota State Rules Portions of the facility are subject to the following Minnesota Standards of Performance: Minn.

5 3. Technical information 3.1 Calculations of Potential to Emit (PTE) Attachment 1 to this TSD contains a summary of the PTE of the facility and detailed spreadsheets describing the calculations and sources of data used, prepared by both the Permittee and MPCA staff. Coating Generally speaking, emissions from the coating operations are based on a mass balance approach. The spray capacity is multiplied by the highest content coating to obtain maximum hourly emissions of the given pollutant. This method was used for EQUI 9 EQUI 14. These hourly PTEs are overly conservative in that they assume all guns are operating at any given hour, using the highest content coating for each pollutant this is not physically possible since any given gun cannot be applying multiple coatings at the same time. The contents and spray capacities are documented in the permit as an appendix. For the remaining coating units, undercoating booths (EQUI 2 and EQUI 16), the Permittee did the calculations based on the maximum number of buses/year (based on overall manufacturing capacity) and maximum materials used/bus (based on 2011 usage). Based on the process design, the flow rate for these two EQUIs is not well defined, so the PTE is based on the overall process rate. This method uses actual hourly emissions (actual historical usage/actual hours per year), so the MPCA adjusted the hourly values up by 25% to account for variability in maximum short term usage. Additionally, a higher transfer efficiency is assumed for EQUI 2 and EQUI 16 (90% and 100% vs. 75%). These booths apply an undercoating to the underside of each coach and within the tubing of the metal frame of the coating (a hose is inserted inside the tubing that makes up the metal frame of the coach and coating is dispensed while the hose is pulled along inside the tubing). The materials used are highly viscous (wax or tar like) which do not become atomized during the application process. Due to the nature of the material and the application processes used, it is reasonable to use a 90% transfer efficiency for the underside coating and a 100% transfer efficiency for the interior tubing coating. Combustion The potential emissions from the EQUI 10 EQUI 14 ovens are calculated based on equipment capacity, the allowable fuel of natural gas, and published emission factors from AP 42 section 1.4. The global warming potentials are from 40 CFR pt. 98 Equation A 1. EQUI 10 and EQUI 11 have a maximum heat input of MMBtu/hr and EQUI 12, EQUI 13, and EQUI 14 have a maximum heat input of MMBtu/hr. EQUI 15 is a generator that runs on distillate fuel (diesel) only. Its maximum heat input is 3.5 MMBtu/hr and a maximum horsepower of 500. Criteria pollutants and HAPs emission factors are from AP 42 section 3.3. The GHG emission factors (nitrous oxide and methane) and global warming potentials are from 40 CFR pt. 98, Table C 1, Table C 2, and Equation A 1. EQUI 15 is an emergency generator, therefore the September 6, 1995 EPA Memo Calculating Potential to Emit (PTE) for Emergency Generators applies and 500 hours/year is used for calculating the emissions. 3.2 Dispersion Modeling The emissions for this facility were previously modeled when the facility was first permitted to construct in Modeling was updated as part of permit action Based on the MPCA s review of the permit record, the previous modeling did not rely on any permit limits and therefore none of the permit conditions are cited as modeling citations. The current potential to emit from the facility is below all regulatory and policy thresholds that would trigger further or updated modeling; therefore, no additional modeling is being done at this time.

6 3.3 Monitoring In accordance with the Clean Air Act, it is the responsibility of the owner or operator of a facility to have sufficient knowledge of the facility to certify that the facility is in compliance with all applicable requirements. For CAM, the Permittee submitted a CAM proposal as required by 40 CFR It can be found in Attachment 3 to this TSD. Further discussion of decisions about CAM can be found in Table 5. 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; and the kind of monitoring found on similar units elsewhere. Table 7 summarizes the monitoring requirements. Table 7. Monitoring Subject Item* COMG 3 Requirement (basis) Volatile Organic Compounds <= tons per year, on a 12 month rolling sum basis [Limit to avoid PSD] What is the monitoring? Recordkeeping: daily records of coating material usage; monthly records for other materials; monthly calculations of emissions, ongoing MSDS records of coating contents Why is this monitoring adequate? Records can be generated on a daily basis for materials used in the coating operations, but less used items such as adhesives and clean up materials will be tracked monthly. Daily records are currently the estimated amount (gallons) of paint for each coach. 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 rolling limits are reasonable for this facility. HAPs Total <= 23.0 tons per year and HAPs Single <= 8.0 tons per year, on a 12 month rolling sum basis [Limit to avoid major HAP source] Recordkeeping: daily records of coating material usage; monthly records for other materials; monthly calculations of emissions, ongoing MSDS records of coating contents Records can be generated on a daily basis for materials used in the coating operations, but less used items such as adhesives and clean up materials will be tracked monthly. Daily records are currently the estimated amount (gallons) of paint for each coach. 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). This would lead to possible paperwork violations and days with negative emissions. Technical Support Document, Permit Number: Page 6 of 10

7 Subject Item* Requirement (basis) What is the monitoring? Why is this monitoring adequate? For these reasons, 12 month rolling limits are reasonable for this facility. Particulate Matter, variable depending on airflow [Limit to avoid PSD] See COMG 4 and COMG 5 for monitoring The COMG 3 units are controlled by panel filters in COMG 4 and COMG 5. The margin is very slim between the IPER limits and the uncontrolled PTE, so these monitoring requirements ensure no additional testing is needed. Opacity <= 20 percent opacity [Minn. R ] COMG 4 PM/PM 10 /PM 2.5 : Control Efficiency of 85% [Limit to avoid PSD] COMG 5 PM/PM 10 /PM 2.5 : Control Efficiency of 85% [Limit to avoid PSD] EQUI 15 Opacity <= 20% Sulfur Dioxide <= lb/mmbtu None Recordkeeping, O & M, corrective actions, daily and periodic inspections Recordkeeping, O & M, corrective actions, daily and periodic inspections Fuel Certifications Other permit requirements in COMG 4 and COMG 5 ensure that this applicable requirement is being met. Monitoring based on the Minnesota Performance Standard for Control Equipment is adequate to have a reasonable assurance of compliance. The permit specifies limits of 85% for all particulates. Monitoring based on the Minnesota Performance Standard for Control Equipment and the approved CAM plan is adequate to have a reasonable assurance of compliance. The permit specifies limits of 85% for all particulates. The SO2 limits are met only using diesel fuel with a sulfur content less than percent by weight. Fuel certifications verify sulfur content of fuel. The potential to emit from the unit is lb SO2/MMBtu due to equipment design and allowable fuels. [Minn. R ] *Location of the requirement in the permit (e.g., EQUI 1, STRU 2, etc.). 3.4 Insignificant activities New Flyer of America Inc Saint Cloud has several operations which are classified as insignificant activities under the MPCA s permitting rules. These are listed in Appendix A to the permit. The permit is required to include periodic monitoring for all emissions units, including insignificant activities, per EPA guidance. The insignificant activities at this Facility are only subject to general applicable requirements. Using the criteria outlined earlier in this TSD, the following table documents the justification why no additional periodic monitoring is necessary for the current insignificant activities. See Attachment 1 of this TSD for PTE information for the insignificant activities. Technical Support Document, Permit Number: Page 7 of 10

8 Table 8. Insignificant activities Insignificant activity Brazing, soldering or welding equipment Individual units with potential emissions less than 2000 lb/year of certain pollutants General applicable emission limit PM, variable depending on airflow Opacity <= 20% (Minn. R ) PM, variable depending on airflow Opacity <= 20% (Minn. R ) Discussion For these units, based on EPA published emissions factors, it is highly unlikely that they could violate the applicable requirement. In addition, these units are typically operated and vented inside a building, so testing for PM or opacity is not feasible. These are the compressed natural gas fueling station and paint prep area. Based on the fuels used for the fueling station and EPA published emissions factors, it is highly unlikely that they could violate the applicable requirement. In addition, all of these units are operated and vented inside a building, so testing for PM or opacity is not feasible. Individual units with potential or actual emissions meeting the criteria in Minn. R , subp. 4(A) (D) Equipment venting PM/PM10 inside a building, provided that emissions from the equipment are: a). filtered through an air cleaning system; and b). vented inside of the building 100% of the time PM <= 0.4 lb/mmbtu Opacity <=20% (Minn. R ) PM, variable depending on airflow Opacity <= 20% (Minn. R ) In the paint prep area, the coach is sanded, washed, and masked. A dust collection system has been installed recently and the vendor is also performing the initial scuffing of the parts prior to shipment. Due to these factors, it is highly unlikely that they could violate the applicable requirement. These are the 13 natural gas fired air makeup units. Their total capacity is roughly 40 MMBtu/hr. Based on EPA published emissions factors and the anticipated use of the units, it is highly unlikely that they could violate the applicable requirement. In addition, these units are vented inside a building, so testing for PM or opacity is not feasible. This is the grit blasting operation controlled by a fabric filter. For these units, it is highly unlikely that they could violate the applicable requirement since the emission rate is roughly 1/3 of the allowable emission rate. In addition, these units are vented inside a building, so testing for PM or opacity is not feasible. 3.5 Permit organization One area of the permit that deviates from MPCA Tempo Guidance is the listing of certain applicable requirements at the group level even though they apply at the individual unit. Specifically: the Industrial Process Equipment Rule (IPER) is listed at COMG 3 and the control equipment requirements are listed at COMG 4 and COMG 5. In general, limits that apply to individual pieces of equipment should be tracked at the unit level and should not be listed as a group. The main reason is if there were noncompliance with a limit by one unit within the group, the computer system would say the whole group was out of compliance. This is a computer tracking issue. For the IPER requirements at COMG 3, the worst case short term emissions are significantly less than the allowable emissions, so there are no permit requirements to conduct performance tests. Therefore, it is highly unlikely that the MPCA would need to track noncompliance with this limit at the individual unit level. Technical Support Document, Permit Number: Page 8 of 10

9 For the control equipment requirements, there are no unit specific parameter limits (all the monitoring is based on inspections and maintenance), so all of the requirements are identical for the members of each group. Listing them as a group significantly shortens the permit and does not hinder the enforcement of the conditions for each member of the group. 3.6 Comments received This section will be completed after the Public Comment period and EPA Review Period. 4. Permit fee assessment This permit action is the reissuance of an individual Part 70; therefore, no application fees apply under Minn. R , subp Conclusion Based on the information provided by New Flyer of America Inc Saint Cloud 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.

41 Computation Job No. 1E+07 Project New Flyer of America, Inc. - St. Cloud Computed GJR Subject Potential Emission Calculations Checked KEG Task IA - Grit Booth Sheets 1 System Specifications: Pressure - 80 psi Nozzles - 3/8-inches Rated Throughput lbs/hr, per gun - The operation period reflects full time operation with a 75% physical operation constraint due to the time required to move a frame assembly in/out of the booth and prep for blasting. A line shift (coach advance) takes place once every four hours. One hour is required for crane movement, securing frame on jack stands, and plugging frame holes to prevent grit from entering frame during blasting. After exiting the grit blasting booth the frame assembly moves directly to the zinc priming booth. Therefore 3 hours is available for grit blasting. 3 hours blasting / 4 hours per line shift = 75% utilization. Uncontrolled Potential Emissions Period Throughput Pollutant Emission Factor Emissions (hrs) (lb/hr abrasive) (lb/1,000 lb abrasive) (lb/hr) (ton/yr) PM PM PM AP42, Chapter , Table Note: Because emissions occur indoors and not subject to wind, PM & PM10 assumed equivalent.

MPCA Adjustments/Calculations from 2013 Operating Permit Review We must also look at any rules that limit the short term potential emissions. Minn. R applies. This rule sets limits based on either process weight rate, or airflow, which ever gives the less restrictive limit. For the blasting operation, vented indoors directly, so we only look at the process weight of the grit. Maximum Process Weight Rate (lb/hr) 1950 Minn. R Table 1 Table 1 (lb/hr) () The controlled emission rate is significantly under the allowable emissions. The grit blasting operation is actually not vented during operation - it is enclosed and the grit is collected and recycled. Once blasting is completed, the unit is opened into the building.

MPCA adjustment from 2013 Operating Permit Review The above are the emissions based on ACTUAL usage per bus * maximum buses per year. This is not really the maximum emissions per year since it is based on actual usage. In addition, for the short-term, it averages the emissions over a 24-hour period rather than basing it on the maximum that could be used in an hour. To account for the uncertainty in the short-term emissions, the adjusted hourly rates are based on information provided verbally by Ken Day. From Ken, it takes at least 38 hrs of welding time per frame. Can calculate the weight of material used/hr-frame from this number. Then assume all 10 frames are inprocess at the same time (in order to make 2190 buses/year, need to have 10 in-process at any point in time). In addition, the annual numbers are adjusted by a factor of 10% to account for the maximum usage per bus.

The Permi ee shall calculate VOC emissions using the following equa ons: VOC (tons/month) = V W V = (A1 x B1) + (A2 x B2) + (A3 x B3) +... W = (C1 x D1) + (C2 x D2) + (C3 x D3) +... where: V = total VOC used in tons/month; A# = amount of each VOC containing material used, in tons/month; B# = weight percent VOC in A#, as a frac on; W = the amount of VOC shipped in waste, in tons/month; C# = amount, in tons/month, of each VOC containing waste material shipped. If the Permittee chooses to not take credit for waste shipments, this parameter would be zero; and COMG D# = weight percent of VOC in C#, as a fraction. [Minn. R , subps. 4 5] COMG Waste Credit: If the Permittee elects to obtain credit for HAPs and/or VOC shipped in waste materials, the Permittee shall either use item 1 or 2 to determine the VOC and/or total and individual HAP content for each credited shipment. 1) The Permittee shall analyze a composite sample of each waste shipment to determine the weight content of VOC, total HAP, and each individual HAP, excluding water. 2) The Permittee may use supplier data for raw materials to determine the VOC and total and individual HAP contents of each waste shipment, using the same content data used to determine the content of raw materials. If the waste contains several materials, the content of mixed waste shall be assumed to be the lowest VOC and total and individual HAP content of any of the materials. [Minn. R , subps. 4 5]

68 Subject Item ID Sequence Number Requirement Material Content. VOC and HAP contents in all materials shall be determined by the Safety Data Sheet (SDS) or the Material Safety Data Sheet (MSDS) provided by the supplier for each material used. If a material content range is given on the SDS or the MSDS, the highest number in the range shall be used in all compliance calculations. If there is information provided in the Regulatory Section of the SDS, the highest number in the range of that section may be used. If a material content range is given on the sheet, the highest number in the range shall be used in all compliance calculations. COMG Other alternative methods approved by the MPCA may be used to determine the VOC and HAP contents. The Commissioner reserves the right to require the Permittee to determine the VOC and HAP solids contents of any material, according to EPA or ASTM reference methods. If an EPA or ASTM reference method is used for material content determination, the data obtained shall supersede the SDS or the MSDS. [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 3. These assumptions are listed in Appendix B of this permit.
