18 Criteria for Compliance with NAAQS 4.0 Criteria for Compliance with NAAQS Sebesta Blomberg performed an air dispersion modeling analysis of the University campus to evaluate compliance with current and revised National Ambient Air Quality Standards (NAAQS), dated November 9, 2009, that are in effect as of writing of this document. The dense collection of particulate emitting sources at the Main Campus Power Plant results in difficulty establishing a compliant air dispersion model under the revised standards for PM 2.5. In order to achieve compliance, necessary modifications to the DRC & pneumatic conveying systems and their stacks will be proposed. 4.1 Air Quality Requirements The University of Iowa is required to be in compliance with NAAQS. The University submits facility air dispersion modeling to the Iowa Department of Natural Resources (IDNR) with most air permit applications prior to construction of new or modified sources. The IDNR air dispersion modeling program allows for historical operating data to be utilized as representative for emission units, including the use of actual emission rates and actual operating times within the modeling analysis. As the University plans future projects, federal-level NAAQS air dispersion modeling may be required. Federal-level NAAQS air dispersion modeling is more stringent than the state-level program requiring emission units to be modeled at potential emission rates and potential maximum operating schedules. The University s Power Plant was analyzed for compliance with both the state-level and federal-level NAAQS procedures. Fine Particulate Matter (PM10) PM 10 concentrations in ambient air are required to meet an average concentration level of less than 150 micrograms per cubic meter, averaged over a 24-hour period. The State of Iowa also continues to require that facilities meet the annual standard where PM 10 is required to meet an average concentration level of less than 50 micrograms per cubic meter, averaged over a one-year period. Ultra-fine Particulate Matter (PM2.5) The PM 2.5 concentration in ambient air is required to meet a 24-hour standard of 35 micrograms per cubic meter. The 24-hour value evaluated for comparison to the standard is the 98 th percentile value averaged over 3 years. The annual standard for PM 2.5 is 15 micrograms per cubic meter. PM 2.5 is both emitted directly from emission sources and is also formed in atmospheric chemical reactions from other pollutants emitted by a facility. Because of this complexity, modeling of PM 2.5 emissions has not been previously enforced. A PM 10 surrogate policy had been in place that allowed facilities to assume that if they were able to meet the PM 10 standard, then they were also considered to be meeting the PM 2.5 standard. This surrogacy policy is in the process of being withdrawn. University of Iowa Page 17 DRC Systems Considerations for NAAQS & NFPA Compliance May 8, 2012 UIowa Project No Sebesta Blomberg Project No

19 Criteria for Compliance with NAAQS Modeling methodology for PM 2.5 continues to be defined. The IDNR originally planned to implement a state-level PM 2.5 NAAQS modeling program on January 1, However, it is believed that this will be delayed at least 1 year. EPA currently requires modeling of PM 2.5 emissions for projects that are deemed to provide major increases in pollutant emissions. This modeling is conducted in accordance with the federal-level NAAQS program. 4.2 Modeling Results The dispersion modeling analyses were completed for both PM 10 and PM 2.5 in order to help develop a strategy for achieving compliance with both pollutant standards. Due to the delay in IDNR implementation of the PM 2.5 program a two-phased approach to compliance has been developed. In the first phase, the DRC and pneumatic conveying system exhausts would be fitted with higher efficiency filters and extended stacks in the vertical orientation that would achieve modeled compliance with current PM 10 requirements. The University would then have the opportunity to later make additional changes that will facilitate PM 2.5 compliance, once the IDNR begins imposing those requirements, and allowing for further development of procedures and definitions for PM 2.5 modeling that are still evolving.

20 Criteria for Compliance with NFPA 5.0 Criteria for Compliance with NFPA Sebesta Blomberg reviewed the NFPA Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing and Handling of Combustible Particulate Solids (NFPA 654, 2006 Edition) and NFPA Committee Report on proposed changes to Standard on Explosion Protection by Deflagration Venting (NFPA 68, 2007 Edition) dated March 2, Below is a summary of our interpretation for DRC system compliance. Refer to Appendix A for supporting information taken from NFPA & Factory Mutual (FM) global documents. 5.1 Silos with Integral Dust Collector The following DRC systems are considered an integral bin vent mounted directly on storage vessel and were evaluated for compliance with NFPA as such; EU-10 Coal Silo #1 EU-11 Coal Silo #2 EU-12 Coal Silo #3 EU-13 Lime Silo EU-14A1 Ash Silo EU-40 Biomass (oat hulls) Silo Compliance Criteria: When a combustible dust hazard exists within a silo with integral bin vent, it should have fire protection in accordance with NFPA 654 Chapter 10 and explosion protection in accordance with NFPA 654 Chapter 7 or a documented risk evaluation acceptable to the authority having jurisdiction must be conducted to determine the level of protection (if any) to be provided. The University had preliminary discussions with the local building inspector / fire marshal in regards to the subject of explosion protection; see Section 6 Modifications for Compliance with NFPA for further details. Background: A bin vent (air material separator) is a dust collector device attached to a larger storage vessel but not provided with a physical separation between the two. The collected dust is returned directly to the large storage vessel. Where bin vents are installed in common with a silo or any other storage vessel the protected volume shall be calculated as the sum of the dust volume of the silo and the dust volume of the collector. For the bin vent to be in compliance with NFPA the silo must also be considered since they are connected with no barrier. The design of the fire and explosion safety provisions for a silo with integral bin vent should be based on a process hazard analysis. Evaluation of the hazard of a combustible dust should be determined by the means of actual test data. Each situation should be evaluated and applicable tests selected. Although conducting a hazard evaluation and testing of dust present in each of the DRC systems is beyond the scope of this study, it is believed that coal, ash and oat hull dust particulates all present some level of hazard.

21 Criteria for Compliance with NFPA 5.2 Size Reduction Equipment with Integral Dust Collector The following DRC systems are considered an integral dust collector mounted directly on size reduction equipment and were evaluated for compliance with NFPA as such; EU-8 Coal Crusher #1 EU-9 Coal Crusher #2 EU-30 Coal Crusher #3, #4, mini-bunker 11 Compliance Criteria: When a combustible dust hazard exists within coal crusher with integral bin vent, it should have fire protection in accordance with NFPA 654 Chapter 10 and explosion protection in accordance with NFPA 654 Chapter 7 or a documented risk evaluation acceptable to the authority having jurisdiction must be conducted to determine the level of protection (if any) to be provided. However, if the total combustible dust volume is less than 8 ft 3 no consideration for explosion protection may be required. The University had preliminary discussions with the local building inspector / fire marshal in regards to the subject of explosion protection; see Section 6 Modifications for Compliance with NFPA for further details. Background: The dust collector device is attached to the size reduction equipment (coal crusher) but not provided with a physical separation between the two. The collected dust is returned directly to the size reduction equipment. For the dust collector to be considered independent of the size reduction equipment would require isolation between the two. Therefore, it would be reasonable to assume that similar to silos with integral bin vents, where dust collectors are installed in common with size reduction equipment, the protected volume shall be calculated as the sum of the dust volume of the size reduction equipment and the dust volume of the collector. For the dust collector to be in compliance with NFPA, the size reduction equipment must also be considered since they are connected with no barrier. The design of the fire and explosion safety provisions for size reduction equipment with integral dust collector should be based on a process hazard analysis. Evaluation of the hazard of a combustible dust should be determined by the means of actual test data. Each situation should be evaluated and applicable tests selected. Although conducting a hazard evaluation and testing of dust present in each of the DRC systems is beyond the scope of this study, it is believed that coal dust particulates present some level of hazard.

22 Modifications for Compliance with NAAQS 6.0 Modifications for Compliance with NAAQS Based on Sebesta Blomberg s review of the University s DRC systems and air dispersion modeling analysis, the following observations and recommendations for each system are included in this section for the University s consideration: Approval by Authority New and/or modified DRC systems will require compliance testing for approval by Iowa DNR. The new and/or modified DRC systems detailed in this study for compliance with NAAQS do not include provisions for explosion or fire protection such as relief panels, fire sprinklers, etc. The new DRC systems do however include design considerations for installation into a classified space such as proper NEMA rating for electrical gear, electrical grounding & bonding, etc. Prior to commencement of design or construction, the University will need to get approval from the authority having jurisdiction for level of protection (if any) which will be required for new and/or modified DRC systems with integral silo and integral size reduction equipment. The University had preliminary discussions with the local building inspector / fire marshal in regards to the subject of explosion protection; see Section 6 Modifications for Compliance with NFPA for further details. Overview of Modifications Below is an overview description of modifications for each DRC system which if made should achieve compliance with NAAQS for PM 10. Raise the discharge elevation of each DRC system exhaust stack Change each DRC system exhaust discharge which is in horizontal to vertical configuration Improve particulate filtration efficiency of each DRC system (see options below) Filter Option 1: Replace existing DRC system bag filters with new bag filters having a particulate filtration efficiency rating as required to meet the permitted emission rate for PM 10 of gr/dscf. Install differential pressure monitoring (with output to BAS) across filter bank. Advantages Potentially the lowest cost solution Minimal interruption to operations May not be considered a modification to existing DRC system, therefore may not trigger any criteria for retroactive NFPA code compliance University of Iowa Page 21 DRC Systems Considerations for NAAQS & NFPA Compliance May 8, 2012 UIowa Project No Sebesta Blomberg Project No

23 Modifications for Compliance with NAAQS Disadvantages Filter manufacturer will not guarantee filtration performance on existing dust collector Exhaust fan upgrade may be required to accommodate for high pressure drop due to modifications to both the stack and filters Filter housing may require repair / replacement if in poor condition Filter Option 2: Replace existing DRC system with new compact filter pack dust collector, such as those offered by Donaldson Torit in their Powercore CPV model. See appendix B for further product information and pricing. Same as with the current configuration, the new dust collector would be directly mounted to the existing silo / coal crusher with no isolation between the two. Advantages Dust collector manufacturer should guarantee gr/dscf filtration performance Product brochure for the Donaldson Ultra Web line filters indicate that gr/dscf filtration performance could be achieved but would require application review and approval by Manufacturer. Replacing older equipment at or near the ends of its useful life Smaller foot-print compared to existing bin vent filter & housing Smaller dirty air plenum (i.e. dust volume) compared to existing bin vent filter & housing No bag filters or cages Easier filter pack change outs New exhaust fan can be sized to accommodate modifications to stack height and potential future secondary filtration to meet PM 2.5 Configurable with options including; o Mountable fan package o Power core AS (Anti-Static) with Ultra Web filters o Delta P plus with timer & analog output in NEMA 9 enclosure (differential pressure) o Solenoid enclosure: NEMA 9 o Electrical grounding and bonding Disadvantages Higher cost compared to option 1 (see appendix B) Replacing existing DRC system with new may trigger criteria for retroactive compliance with NFPA codes.

24 Modifications for Compliance with NAAQS Filter Option 3: Replace existing DRC system with new dust collector w/hopper, such as those offered by Donaldson Torit in their Powercore CPC model. The filter portion of the CPC model is the same as the CPV model; however this dust collector also includes a hopper bin for collection of the dust. The new dust collector would preferably be located on top of the silos / coal crushers. The new dust collector would be connected to the existing silo / coal crusher by ducting dust laden air to the dust collector hopper and a rotary valve at bottom of hopper for dust return to silo / coal crusher. Advantages Dust collector manufacturer should guarantee gr/dscf filtration performance Product brochure for the Donaldson Ultra Web line filters indicate that gr/dscf filtration performance could be achieved but would require application review and approval by Manufacturer. Isolation between silo volume and filters (static charge in filters is potential ignition source) Replacing older equipment at or near the ends of its useful life No bag filters or cages Easier filter pack change outs New exhaust fan can be sized to accommodate modifications to stack height and potential future secondary filtration to meet PM 2.5 Configurable with options including; o Mountable fan package o Power core AS (Anti-Static) with Ultra Web filters o Delta P plus with timer & analog output in NEMA 9 enclosure o Solenoid enclosure: NEMA 9 o Electrical grounding and bonding Disadvantages Higher cost compared to option 1 and option 2 Replacing existing DRC system with new may trigger criteria for retroactive compliance with NFPA code More complex design that option 1 or 2 Dust collector w/hopper would require explosion isolation from the silo / coal crusher and explosion protection (deflagration venting) for the dust collector. Limited space is available above existing silos and coal crushers. May require re-location and/or potentially significant modifications to existing layout.

38 Modifications for Compliance with NFPA 7.0 Modifications for Compliance with NFPA Based on Sebesta Blomberg s review of the University s DRC systems and NFPA analysis, the following observations and recommendations for each system are listed below for the University s consideration: 7.1 Silos with Integral Dust Collector The following DRC systems are considered an integral bin vent mounted directly on storage vessel EU-10 Coal Silo #1 EU-11 Coal Silo #2 EU-12 Coal Silo #3 EU-13 Lime Silo EU-14A1 Ash Silo EU-14A2 Ash Truck Loading EU-40 Biomass (oat hulls) Silo The existing silos & integral dust collectors do not have fire or explosion protection. Modifications (or replacement with new) to existing DRC systems have been identified in this study for compliance with NAAQS. Typically, when modifications are made to an existing system, the system must then retroactively adhere to the current standards. New DRC systems would include features such as differential pressure monitoring across the filters, electrical grounding & bonding, anti-static filters (if available) and electrical components rated for installation in combustible dust hazard location (if applicable). Sebesta Blomberg recommends that the University discuss with authority having jurisdiction what level of protection (if any) would need to be added to the existing silos & integral new DRC systems to comply with NFPA. dated April 11, 2012 from Ed Scherrer, University of Iowa During a general visit with the State Building Inspection/Fire Marshal in their Des Moines office this morning, I had an opportunity to discuss the NFPA/explosion vent sizing issue with their plan reviewers and administrators. They understand the situation of the combined areas (DRC and silo), the relative magnitude of the explosion vent area per NFPA and agree with Tom Lauer s assessment that this is one of those instances where NFPA does not apply. When we get into design and have enough detail that they can understand the scope and breathe of the project, we will send them a project exemption form in order to solidify this position. Sebesta Blomberg estimated an order of magnitude minimum venting area which would be required to protect the coal and biomass silos & integral dust collectors using the deflagration venting method. The ash silo volume was unknown so not included in the calculations.

39 Modifications for Compliance with NFPA Below are estimates for minimum vent closure areas to protect the silo & integral dust collector. The estimated vent areas are based on no vent ducting required (i.e. vent closure is on silo wall and vents directly to atmosphere). If vent ducting was required, which would be the case if all or a portion of the silo vent closure area was installed on the dust collector housing located on top of silo in a penthouse, the minimum vent area would increase to compensate for this added restriction. Coal silos vent area estimates Calculated venting area was based on NFPA 68 guidelines using the following assumed values; Kst of 200 bar-m/s (conservative value) 100 mbar burst pressure 10 bar max pressure of deflagration (conservative value) 0.12 bar reduced pressure after venting Coal silo #1 (20 ft diameter x 79 ft height) 285 ft2 minimum vent area (approx 6% of total surface area of silo) total of 14 explosion 44.5 x 68 each Coal silo #2 (20 ft diameter x 79 ft height) 285 ft2 minimum vent area (approx 6% of total surface area of silo) total of 14 explosion 44.5 x 68 each Coal silo #3 (40 ft diameter x 129 ft height) 1170 ft2 minimum vent area (approx 7% of total surface area of silo) total of 57 explosion 44.5 x 68 each Biomass (oat hull) silo vent area estimate Calculated venting area was based on NFPA 68 guidelines using the following assumed (conservative) values; Kst of 200 bar-m/s (conservative value) 100 mbar burst pressure 10 bar max pressure of deflagration (conservative value) 0.12 bar reduced pressure after venting Oat hull silo #1 (10 ft diameter x 81 ft height) 103 ft2 minimum vent area (approx 4% of total surface area of silo) total of 5 explosion 44.5 x 68 each Based on the calculated minimum venting areas for the silos & integral bin vents, it is apparent that the silo bin vent filter housing does not have enough surface area to install venting to protect both the silo and bin vent filter housing. It would be difficult (if possible at all) to install this many venting panels on the existing silos. To determine the feasibility would require a thorough review of structural design of existing silos which is beyond the scope of this study.

40 Modifications for Compliance with NFPA 7.2 Size Reduction Equipment with Integral Dust Collector The following DRC systems are considered an integral vent mounted directly on size reduction equipment EU-8 Coal Crusher #1 EU-9 Coal Crusher #2 EU-30 Coal Crusher #3, #4, mini-bunker 11 The existing coal crushers & integral dust collectors do not have fire or explosion protection. Modifications (or replacement with new) to existing DRC systems have been identified in this study for compliance with NAAQS. Typically, when modifications are made to an existing system, the system must then retroactively adhere to the current standards. New DRC systems would include features such as differential pressure monitoring across the filters, electrical grounding & bonding, anti-static filters (if available) and electrical components rated for installation in combustible dust hazard location (if applicable). Sebesta Blomberg recommends that the University discuss with authority having jurisdiction what level of protection (if any) would need to be added to the existing coal crushers & integral new DRC systems to comply with NFPA. dated April 11, 2012 from Ed Scherrer, University of Iowa The Bldg Inspector/Fire Marshal folks indicated that if FM Global had a position (like the explosion panels) they normally had a tendency to follow FMG s lead. Tom Lauer has indicated that he is not aware of anyone worrying about explosion panels for coal crushers because they were normally flooded and not capable of the explosive environment needed to cause a problem. I would think that explanation with our project exemption would apply to the crushers. dated April 12, 2012 from Tom Lauer, FM Global Ed is correct, the crushers proper do not typically require explosion relief. We do recommend dust collect at dust liberation points upstream and downstream of the crushers, and that collector, depending on its size, would require venting. 7.3 Dust Collector Ash Truck Loading Exhaust The ash truck loading exhaust dust collector (EU-14A2) will need to be further evaluated for what if any fire and/or explosion protection would be required depending what modifications to meet NAAQS compliance are adopted.

Published prices are subject to change without notice and shall not be binding on Donaldson Company, Inc. (Donaldson) until reduced to writing signed by Donaldson. All prices are F.O.B. Donaldson s plant and do not include transportation costs or charges relating to transportation, which costs and charges shall be solely the responsibility of Purchaser. Prices quoted include standard packing according to Donaldson s specifications. Special packing requested by Purchaser, including packing for exports, shall be paid by Purchaser as an additional charge. 2. Taxes. To the extent legally permissible, all present and future taxes, imposed by any Federal, State, Local or Foreign authority, which Donaldson may be required to pay or collect, upon or with reference to the sale, purchase, transportation, delivery, storage, use or consumption of goods or services, including taxes upon, or measured by the receipts therefrom, shall be paid by Purchaser. Amounts covered hereby shall be added to the price, or billed as a separate item as the law may require or as Donaldson may determine. No offset against or reduction in price shall be allowed Purchaser by reason of taxes owed, paid or payable by Purchaser, or charged to Purchaser s account. 3. Credit and Payment. Credit accounts will be opened only with firms or individuals approved by Donaldson s Credit Department. Unless otherwise provided, in any case where delivery is made on credit, Purchaser shall have thirty (30) days from date of the invoice in which to make payment for the goods. Unless prohibited by law (in which case accounts past due shall bear interest at the rate of eight percent (8%) per annum), accounts past due shall bear interest at the then prime rate charged by US Bank N.A. Donaldson reserves the right at anytime upon notice to Purchaser, to alter or suspend credit, or to change the credit terms provided herein, when in its sole opinion the financial condition of Purchaser so warrants. In addition, Donaldson may at anytime, with or without notice to Purchaser, and at its option, suspend work and shipment under this contract if, in Donaldson s sole opinion, the financial condition of Purchaser so warrants. In such cases, in addition to any other remedies herein or by law provided, cash payment or satisfactory security from Purchaser may be required by Donaldson before credit is restored or Donaldson continues performance. If Purchaser fails to make payment or fails to furnish security satisfactory to Donaldson, then Donaldson shall also have the right to enforce payment of the full contract price of the work completed and in process. Upon default by Purchaser in payment when due, Purchaser shall pay immediately to Donaldson the entire unpaid amounts for any and all shipments, made to Purchaser irrespective of the terms of said shipments and whether said shipments are made pursuant to this contract or any other contract of sale between Donaldson and Purchaser, and Donaldson may withhold all subsequent shipments until the full account is settled. Acceptance by Donaldson of less than full payment shall not be a waiver of any of its rights hereunder. 4. Risk of Loss, Title. The risk of loss of the goods shall pass to Purchaser as soon as they are deposited with the carrier for shipment to Purchaser, but title to the goods shall remain in Donaldson until the purchase price therefore has been paid. 5. Shipment. All shipments shall be F.O.B. Donaldson s plant and the date of shipment shall be contingent upon the date of acceptance of Donaldson s offer.

Donaldson shall have the right to ship all of the goods at one time or in portions from time to time within the time of shipment. This contract shall be deemed separable as to the goods sold. Purchaser may not refuse to accept any lot or portion of the goods shipped hereunder on the grounds that there has been a failure to ship any other lot or that goods in any other lot were nonconforming. Any such default by Donaldson will not substantially impair the value of this contract as a whole and will not constitute a breach of the contract as a whole. The goods shall be deemed tendered to Purchaser when they have been deposited with the carrier. 6. Inspection and Acceptance. Purchaser shall have the right to inspect the goods upon receipt of them and shall have the opportunity, at that time, to run adequate tests to determine whether the goods shipped conform to the specifications of this contract. Purchaser shall recompense Donaldson, at the contract price, for all goods used in testing and Purchaser shall bear any expense incurred in the inspection of the goods used in testing whether or not the goods are nonconforming. Failure to inspect the goods or failure to notify Donaldson in writing that the goods are nonconforming within ten (10) days of the receipt of the goods by Purchaser shall constitute a waiver of Purchaser s rights of inspection and rejection for nonconformity and shall be equivalent to an irrevocable acceptance of the goods by Purchaser. 7.

63 Appendix B: Donaldson CPV Dust Collector Product Literature & Pricing (14/65) Donaldson Industrial Air Filtration Product Disclaimer Donaldson Industrial Air Filtration collectors (Donaldson Torit ) are marketed, sold and manufactured by Donaldson for a variety of applications. Some of these applications (such as grain handling/processing and woodworking) include inherent fire and explosion hazards. Donaldson wishes to state its rights and responsibilities and the rights and responsibilities of our customers and equipment users. Donaldson is neither an expert nor a certified consultant for fire, spark, or explosion detection, suppression and control. Furthermore, our customers and equipment users acknowledge that there are many factors, which contribute to fires, and explosions, which are out of the control of Donaldson. These factors include but are not limited to the design and maintenance of ductwork, fire suppression and detection systems as well as worker procedure and error. Therefore, Donaldson assumes no liability for the fitness of any of its products (with respect to fires and explosions) for a particular installation or application. Donaldson Industrial Air Filtration products are available with sprinkler taps and/or explosion vents, but the fitness of these devices for a particular application or installation is the responsibility of the customer. Donaldson recommends that all dust control system designs be reviewed and approved by an expert consultant who is responsible for the integrity of the system design and compliance with locally accepted codes. Donaldson also recommends that proper maintenance procedures and work practices be followed to maintain any dust control system in safe operating condition. Donaldson requests that customers, equipment users and consultants work with Donaldson Industrial Air Filtration during the proposal and design stages of projects so that Donaldson may recommend an appropriate dust collector for a given dust control system. Donaldson may provide referrals to suppliers of equipment designed to detect and/or suppress sparks, fires and/or explosions, but Donaldson does not assume any responsibility for such referrals. This Disclaimer is to be included with all quotes and proposals made by Donaldson Industrial Air Filtration for its products which are to be used in grain handling/processing applications or other applications with inherent fire and explosion hazards. Acceptance and/or approval of quotes and/or proposals include the acceptance of this Disclaimer.
