1.2 Facility Description

Heron Lake BioEnergy is a dry mill corn ethanol production facility. Permit No. 06300025-004 authorizes the facility to produce 59.9 million gallons annually of 200-proof ethanol (actual production capacity is believed to be 65 to 67 million gallons per year of 200-proof ethanol based on operating experience). In addition to ethanol, the facility produces dried distillers grains with solubles (DDGS) and corn oil.

Pollutants emitted are volatile organic compounds (VOC), particulate matter (PM), particulate matter smaller than 10 microns (PM10), particulate matter smaller than 2.5 microns (PM2.5), nitrogen oxides (NOX), sulfur dioxide (SO2), carbon monoxide (CO), hazardous air pollutants (HAP), and greenhouse gases (GHG; primarily CO2).

Facility emission sources are grain receiving, handling, and milling; fermentation and distillation; DDGS production, storage, and handling; natural gas and propane combustion; product and denaturant storage and loadout; and equipment leaks (valves, flanges, etc.), emergency engines, and cooling towers.

The facility employs a Regenerative Thermal Oxidizer (RTO) to control VOC and HAP emissions from DDGS drying and distillation processes. A wet (also known as a ‘CO2’) scrubber controls VOC and HAP emissions from the fermentation process. The facility employs several baghouses to control particulate matter emissions. The (formerly coal) natural gas-burning boiler provides process steam. The large denaturant and product storage tanks are equipped with internal floating roofs to control


VOC and HAP emissions from evaporative losses. The ethanol loadout rack for trucks is equipped with a flare to control VOCs, and ethanol transported by rail loadout is restricted to dedicated ethanol rail cars. Emissions from equipment leaks are controlled through an inspection and maintenance program.

1.3 Description of the Activities Allowed by this Permit Action

This permit action is a Major Amendment (DQ 4640) and authorizes and/or makes the following changes:

a. The Total Facility permitted annual 200-proof ethanol production limit is increased from 59.9 million gallons per year to 72.25 million gallons per year (12-month rolling sum).

b. Total Facility modeling requirements were revised based on the current modeling requirements template language and results of modeling conducted for permit No. 06300025-005. The revised requirements are located in the Total Facility and FS 001 subject items. Refer to the discussion at Section 3.2 in this document.

c. Construction is authorized through equipment flexibility requirements for various facility processes. As part of providing equipment flexibility, process throughput capacities were added to each of these processes, to verify if stack testing is conducted at worst case conditions (as defined at Minn. R. 7017.2005, subp. 8). The following is a list of processes provided equipment flexibility, along with the corresponding process capacity:

i. SV 001 grain receiving – 416.67 tph

ii. SV 002 hammer milling – 109.2 tph

iii. SV 003 fermentation – 1050 gallons per minute from a liquefaction tank into any fermenter

iv. SV 008 DDGS handling and loadout – 400 tph

In addition, lb/hr PM, PM10, and PM2.5 SV 001, SV 002, and SV 008 lb/hr Title I limits were added for each stack/vent, based on the 0.004 gr/dscf limits and rated airflow capacity of each stack. These limits are necessary to restrict facility emissions of these pollutants to avoid PSD and are necessary because the permit allows equipment flexibility. The lb/hr limits ensure the addition, replacement, or modification of equipment venting through these stack/vents doesn’t cause the facility to become a major PSD source.

Individual lb/hr HAP (acetaldehyde, acrolein, formaldehyde, and methanol) limits and stack testing were added to SV 003, SV 004, SV 007, and EU 035, and HAP control efficiency requirements were added to HAP control equipment (CE 003, CE 005, and CE 028) to ensure the facility remains a minor source under 40 CFR pt. 63.

The SV 003, SV 004, and SV 007 HAP limits are derived from actual stack test results plus a 50% margin of error. The EU 035 HAP limits are based on uncontrolled lb HAP/ton DDGS emission factors furnished by the facility designer, ICM, Inc., and assumed control efficiencies of 98%.

HAP control efficiencies were estimated to be the same as the 98% VOC control efficiency.

The permit also authorizes use of limited liquid feedstocks (liquid molasses and off-specification liquid sugar) and grain (in addition to corn) in the fermentation process. Emissions from the use


of grain are worst case compared to liquid feedstocks because liquid feedstock receiving does not generate particulate matter emissions produced by grain receiving.

c. Various emission limits have been increased to accommodate the ethanol production increase. These limits are:

i. SV 003 VOC limit increased from 5.0 lb/hr to 6.0 lb/hr as total mass VOC; ii. SV 004 PM, PM10, and PM2.5 increased limits from 2.65 lb/hr to 3.25 lb/hr for each

pollutant; SO2 limit increased from 6.3 lb/hr to 7.73 lb/hr; NOX limit increased from 1.9 lb/hr to 2.33 lb/hr; VOC limit increased from 7.0 lb/hr to 8.59 lb/hr; and CO limit increased from 9.42 lb/hr to 11.56 lb/hr;

iii. SV 007 VOC limit increased from 11.0 lb/hr to 13.27 lb/hr.

These limits were cited as ‘Title I Condition: 40 CFR § 52.21 BACT-equivalent’ limits in permit No. 06300025-004, however, the citations have been revised to ‘Title I Condition: 1990 CAAA; Title I Condition: To avoid major source threshold under 40 CFR § 52.21 and Minn. R. 7007.3000’ (refer to discussion under ‘Other Changes’ in Section 1.3). The increase of these limits is permissible because the facility is a non-major PSD source, however, the processes subject to the increased limits have not been changed and therefore, the (formerly cited as) BACT-equivalent limits remain applicable. To preserve these (formerly cited as) BACT-equivalent limits while allowing these limit increases, the (formerly cited as) BACT-equivalent limits were converted from lb/hr limits to lb/process rate (e.g., lb VOC/ton DDGS produced) limits. As stated above, the lb/process rate limits are now cited as ‘Title I Condition: 1990 CAAA; Title I Condition: To avoid major source threshold under 40 CFR § 52.21 and Minn. R. 7007.3000’, and the new lb/hr limits are cited as Title I Conditions to avoid the major source threshold at § 52.21(b).

d. SO2 SV 004 testing and test frequency plan submittal requirements were added. PER 004 did not require SV 004 SO2 testing. A 2008 test showed compliance at 0.103 lb SO2/hr. However, PER 005 allows an increase in ethanol and DDGS production, and increases the SV 004 SO2 limit from 6.3 lb/hr to 7.73 lb/hr. Therefore, testing is warranted.

e. A change in the method of operation of EU 035 is permitted by authorizing the Permittee to combust natural gas in EU 035 and use EU 035 as an alternate emission control device (direct flame afterburner; also referred to as CE 028) for processes controlled by the RTO (CE 005). Natural gas burners were installed in EU 035 in 2011 during a planned shutdown, and coal combustion support equipment was retired so that EU 035 can no longer combust coal. A Title I Condition restricting permitted fuels to natural gas and propane was added to prohibit coal combustion. There are requested emission limit increases for the boiler for when the boiler operates as both a steam generator and a control device. These limits were ‘Title I BACT-equivalent’ limits in permit No. 06300025-004, but increasing the limits does not require re-opening the original BACT analysis because:

i. The proposed limit increases are due to the requested change in the method of operation of EU 035 (from a coal-fired steam generator to a natural gas-fired steam generator and a direct flame afterburner),

ii. The proposed change in the method of EU 035 operation is not in the scope of the backward-looking Prevention of Significant Deterioration (PSD) permitting process (based on the August 2007 PSD permit application for the December 2010 permit No. 06300025-004 when coal was a permitted boiler fuel),


iii. The facility is currently a non-major PSD source, and the change in the method of EU 035 operation occurred while the source was a non-major PSD source.

In addition, all EU 035 Title I BACT-equivalent limits have been replaced by Title I limits to avoid PSD applicable when EU 035 is not also operating as a control device. The elimination of the EU 035 BACT-equivalent conditions is appropriate because the boiler has been physically changed (by the installation of natural gas burners) and therefore the BACT-equivalent limits based on coal combustion are no longer applicable. Also, because the physical change is made while the facility is a non-major PSD source, retention of BACT-equivalent limits is not warranted. MR 006 has been added to the permit and it contains requirements applicable to the EU 035/CE 028 firebox temperature monitor.

f. The Methanator (EU 036) and Methanator flare (CE 008) are removed.

g. All requirements pertaining to coal combustion and ash handling are removed because the Permittee converted the bubbling bed boiler (EU 035) from a coal-fired boiler to a natural gas/LPG-fired boiler circa November 2011. These requirements were for emission sources, CEMS, and control equipment.

EU 035 40 CFR pt. 60, subp. Db requirements were revised accordingly due to the use of NG and elimination of coal as fuel. The opacity limit was removed, 40 CFR pt. 60, subp. Db was removed from the PM limit citation, and the NOX limit was revised accordingly. The 0.20 lb/mmBtu SO2 limit from 40 CFR § 60.42b(k)(1) does not apply based on the provision at 40 CFR § 60.42b(k)(2).

h. The 40 CFR pt. 60, subp. Db requirement from 40 CFR § 60.48b(f) was added to EU 035. This requirement specifies that during NOX CEMS breakdown, emissions data can be obtained by standby monitoring systems, Reference Methods 7 or 7A, or other approved reference method.

i. The EU 035 mercury emission limit and mercury control requirements were removed because coal is no longer a fuel option.

j. EU 035 CO and PM testing required no later than December 31, 2011, have been removed because these requirements were completed.

k. CE 028 requirements were added for when the NG boiler (EU 035) is operated as a direct flame afterburner to control sources currently controlled by the CE 005 RTO. These requirements mimic the requirements for the RTO.

l. FS 001 name was changed to ‘Facility Road Requirements’ to better reflect the requirements in this subject item. The requirements were updated based on modeling results for permit No. 06300025-005, and the May 2011 Paved Road Fugitive Emissions policy memorandum (modeling results and permitted operating conditions resulted in imposing the tier 3 paved road dust control requirements from the May 2011 memorandum). In addition, the daily grain receiving tonnage limits were moved to GP 001 because that is a more appropriate location in the permit for these requirements.

Included or Closed Actions and Descriptions

DQ 3380 (Received January 31, 2011) – Administrative Amendment for 120 day test deadline extension for SV 004 (RTO VOC), SV 005 (EU 035 boiler PM10 and PM2.5), and SV 007 (DDGS Cooler VOC). The tests were due 90 days after the December 16, 2010 issuance date of permit No. 06300025-004; the Permittee requested a 120-day extension so the deadline is 210 days after issuance of permit No.


06300025-004, so that the revised deadline was July 14, 2011. This testing was completed in June 2011 and compliance was demonstrated for SV 004 and SV 007. The SV 005 PM10 and PM2.5 tests were noncompliant but retesting in 2012 demonstrated compliance after the fuel switch from coal to natural gas, so all of these Table C testing requirements were removed from the permit. Requirements for future testing for these same pollutants was added to the permit, at test frequencies based on the MPCA test frequency guidance. (Included)

DQ 3528 (Received June 2, 2011) – Administrative Amendment for a 365-day extension of the completion deadline for the Building Capture Efficiency Study from June 30, 2011 to June 30, 2012. The study was submitted in September 2011. (Included)

DQ 3694 (Received October 11, 2011) – Administrative Amendment to clarify requirements of boiler (EU 035) SO2, opacity, and ammonia flowrate monitoring so it is clear these requirements only apply when coal is combusted in the boiler. (Included)

DQ 3771 (Received December 12, 2011) – Administrative Amendment for a 120-day extension of the fence installation due date. The original due date was 365 days after the December 16, 2010 issuance date of permit No. 06300025-004 and an additional 120 days would make the new due date at April 14, 2012. The fence is installed based on MPCA staff observation during a June 4, 2013 MPCA air quality inspection. In addition, note the cover page of the application indicated the Permittee initiated natural gas firing in the boiler on November 7, 2011. (Included)

DQ 3837 – Revised Modeling Pre-application received February 8, 2012. (Included)

DQ 4399 – Re-opening for updating SV 003/CE 003 operating parameters based on January 2012 stack testing. Parameter revisions are pressure drop >2.0 and <28.0 inches w.c., liquid flow rate >50.0 gpm, and scrubber additive rate >4.0 gph. Refer to DQ 4907 information below. Note the additive flow rate was again updated by the May 2014 SV 003 test (DQ 4907). (Included but note DQ 4907 revises the additive flow rate again)

DQ 4508 – Revised/updated Modeling Pre-application received August 26, 2013. (Included)

DQ 4907 – August 12, 2014 NOC for May 2014 SV 003 testing that revised the CE 003 additive flow rate to >5.7 gph. (Included)

Other Changes

All citations of Title I Condition: 40 CFR § 52.21 BACT-equivalent Limit and Minn. R. 7007.3000 were revised to Title I Condition: 1990 CAAA; Title I Condition: To avoid major source threshold under 40 CFR § 52.21 and Minn. R. 7007.3000. This revision was necessary because ‘BACT-equivalent’ is a term from a November 1998 EPA memorandum that provides guidance for enforcement action against sources that violated new source review (NSR) permitting requirements. ‘BACT-equivalent’ is used in the memorandum discussion regarding sources whose actual emissions never exceeded the NSR major source threshold. The term ‘BACT-equivalent’ is not defined under NSR regulations, and therefore use of the term is inappropriate in a Title I Condition citation.

Emission unit and fugitive emission source names were revised to allow the transfer of data for this facility during the upcoming transition from the MPCA Delta permitting database to a new permitting system known as TEMPO 360. This transition should occur during the first half of 2015.

Additional requirement language was added to all required stack tests to ensure testing is conducted at worst case conditions including short-term process throughput limits (SV 001, SV 002, SV 003, SV 004,


and EU 035). Also added language to allow testing to occur during a 60 day window prior to the test due date without resetting the test due date.

Total Facility: Removed 40 CFR § 52.21(r)(6) reasonable possibility language because the facility is not a PSD major source (in part due to the June 23, 2014 Supreme Court decision on regulation of greenhouse gas emissions under the PSD program).

The building capture efficiency study (BCES) requirements were removed because the study was submitted. Although the MPCA never formally accepted the results of the study due to measured uncontrolled emission factors being several fold greater than comparable emission factors in AP-42 ch. 9.9.1, the Permittee used a relatively 95% capture efficiency in all calculations of uncaptured grain receiving and DDGS loadout for permit action 005. This 95% capture efficiency was notably lower than the capture efficiency values (of >99% for PM10 and > 98% for PM2.5) measured by the study.

Three requirements related to emission rate and stack parameter changes for state-only air emissions risk assessment (AERA) modeling requirements were removed because the facility no longer uses coal for boiler fuel, and coal was the only reason that an AERA was conducted. Appendix II that contained the pollutant emission rates that were evaluated by the AERA process, was also removed.

Removed the recordkeeping requirement for daily ethanol production and daily purchases of coal, propane, and natural gas (note the daily ethanol production recordkeeping requirement was duplicative with another ethanol production recordkeeping requirement in the permit, so the removal of this requirement does not eliminate the requirement for daily (and monthly) ethanol production recordkeeping). These are vestigial requirements from the first permit (No. 06300025-001) issued in 2005 that was supposed to be a state permit that limited emissions below pt. 70 and PSD major source thresholds. The facility is currently a Pt. 70 source, but a non-major PSD and pt. 63 source, and other (Title I) requirements in the permit are used to verify the facility is maintaining this status.

Removed the 3-hour rolling average beer production rate recordkeeping requirement. This requirement was vestigial from the first permit, and was used to show compliance with a beer production limit that was used to restrict facility emissions to less than pt. 70 and PSD major source thresholds. The beer production limit was removed by PER 004, but the recordkeeping requirement was retained and the citation was revised to Title I Condition: to avoid 40 CFR pt. 63 major source thresholds. The current draft permit addresses the lack of limits to avoid 40 CFR pt. 63 by imposing lb/hr HAP limits under SV 003, SV 004, SV 007, and EU 035, as well as HAP control efficiencies under CE 003, CE 005, and CE 028 to maintain non-major source status under 40 CFR pt. 63.

The ethanol production limit and daily recordkeeping requirement citations were revised from ‘Title I to avoid major source classification under 40 CFR § 63.2’, to ‘Title I Condition: To avoid major source threshold under 40 CFR § 52.21(b) and Minn. R. 7007.3000; Title I Condition: To avoid major source threshold under 40 CFR § 63.2 and Minn. R. 7011.7000’. The monthly ethanol production recordkeeping requirement citation was changed from a Title I Condition to Minn. R. 7007.0800, subps. 4 and 5 because only the daily ethanol production recordkeeping requirement needs to be a Title I Condition.

Stack test report submittal requirements were revised to reflect up-coming revisions to the Minn. Rule requirements for report submittal. The changes allow several options for electronic submittal of the test report.

GP 001: Removed the requirement to keep doors closed on the grain receiving building during grain receiving and DDGS loadout, due to the completion of the Building Capture Efficiency Study. Added 95% capture efficiency requirements for EU 001, EU 002, and EU 038 (Truck Receiving Pits 1 and 2, and DDGS


Loadout Spout, respectively) because this value was used in calculating PM10 and PM2.5 emissions used in modeling and PM, PM10, and PM2.5 emission calculations.

GP 002: Removed GP 002 for fabric filters. Other than a reference to the CE identification numbers for the location in the permit of applicable requirements, there were no requirements in GP 002. All references in the permit to GP 002 were replaced with a reference to the applicable CE identification number.

GP 004: The 3,905,000 gallon total fermentation tank volume limit was removed. This limit was in the initial permit and cited as Minn. R. ch. 4410. This chapter is the Minnesota Environmental Review rules chapter. When the initial permit was issued in 2005, Minnesota environmental review rules contained a 5,000,000 gallon per year ethanol production increase threshold for environmental review. However, that rule-based threshold was superseded in 2010 when Minn. Stat. 116D, subd. 2a(a) was promulgated. The statute exempts ethanol plant production increases from being subject to the requirement to prepare an environmental assessment worksheet (EAW) due to the increased ethanol production, providing no other EAW trigger applies. Due to the statute superseding the rule, it is reasonable to remove the fermentation tankage volume limit.

GP 006: Removed the notification requirement for installation of controls that accompanies the initial startup notification because the notification was made in September 2007.

GP 007: Moved the GP 007 flare requirements to CE 010 (that were derived from 40 CFR 40 CFR § 60.18) because CE 010 is now the only flare at the facility. GP 007 steam-assisted flare requirements were not moved to CE 010 because CE 010 is an air-assisted flare. Also, some of the requirements language was revised to remove erroneous references to 40 CFR pt. 60, subp. A (because CE 010 is not subject to 40 CFR pt. 60). As part of the revisions, the requirement to use Method 9 for determining opacity was removed because 40 CFR § 60.18 does not require the determination of flare emissions opacity, but the requirement to use Method 22 for determining the presence of visible emissions, was retained.

GP 009: Was deleted because it was just a reference for the location of SO2 limits located at SV 004 and EU 035. This group was established by PER 001 and it contained a limit and recordkeeping requirements to avoid the pt. 70 and PSD permitting 100 tpy threshold in effect when PER 001 was issued. The facility is now a pt. 70 source and PSD non-major source, and no longer burns coal in EU 035. The limited SO2 PTE is well below the 250 tpy PSD threshold. Therefore there is no need to limit and track 12-month SO2 emissions.

GP 010 Fuel Limited Group: This group established by PER 001 contained three requirements to limit emissions from the total facility to less than 40 CFR pt. 63 major source thresholds. These requirements were removed because they were no longer necessary due to the addition of lb/hr HAP limits under SV 003, SV 004, SV 007, and EU 035, as well as HAP control efficiencies under CE 003, CE 005, and CE 028 to maintain non-major source status under 40 CFR pt. 63.

GP 011 Coal Group: This group contained two requirements limiting the quantity of coal combusted. Coal is no longer a permitted fuel so the requirements were removed and the group was retired.

GP 012 GHG Group: This group contained a requirement that the Permittee must meet the renewable fuels requirements in 40 CFR pt. 80 if the Permittee desires to obtain renewable identification numbers (RIN) for ethanol production in excess of 55 million gallons per year. The MPCA is not authorized to implement this part, and this requirement does not belong in a 40 CFR pt. 70 operating permit. The single requirement in this group was removed and GP 012 was retired.


SV 001: SV 001 (EU 001 and EU 002) grain receiving is limited to 12 hours per day due to using this assumption in PM10 and PM2.5 modeling. The 416.67 tph grain receiving process throughput limit is the value used to calculate uncaptured PM10 and PM2.5 emissions used in modeling even though receiving capacity is slightly higher at 420 tph. Therefore, the permit prohibits increasing this limit unless PM10 and PM2.5 remodeling is conducted. The PM, PM10, and PM2.5 testing trigger date was revised based on the most recent test date of June 1, 2011. Permit 004 required testing at 60-month intervals based on a trigger date of August 6, 2008. However, the Permittee tested SV 001 on June 1, 2011, and therefore the testing trigger date is reset to June 1, 2011. The 60-month test interval does not change based on the results of the 2011 testing.

SV 002: The PM, PM10, and PM2.5 testing trigger dates were revised for the same reason and in the same manner as descried above for SV 001.

SV 003 VOC test frequency was revised based on the results of the May 13, 2014 stack test. The measured VOC emission rate was 3.16 lb/hr which is 63% of the 5.0 lb/hr emission limit. The test frequency was revised from a 60-month interval to a 36-month interval.

SV 004: SV 004 VOC test Table C requirement were moved to Table A because re-test demonstrated compliance, and test results indicated a 60-month test frequency interval. SV 004 PM10 and PM2.5 testing requirements were changed from a one-time test due one year after issuance of permit No. 06300025-004 (issued in December 2010), to annual testing based on June 2011 test results that were greater than 90% of limit. SV 004 CO and PM test interval start date was reset from 8/1/2008 to 6/9/11 due to compliant 6/9/11 SV 004 CO and PM tests with test results that support a 60-month test interval.

Added SV 004 and EU 035 process throughput limits to verify if stack testing is conducted at worst case operating conditions. For SV 004 and EU 035, these limits are for the beer flow in gallons per minute from the beer well (EU 017) to the beer column (EU 026), and for DDGS output from DDGS Dryer B (EU 034). Both of these process throughputs directly impact emissions vented to the RTO (CE 005)/NG-fired boiler/direct flame afterburner (EU 035/CE 028), and the emissions from the RTO stack/vent SV 004.

A 425˚F DDGS dryer exhaust temperature limit was added to the permit under each dryer emission unit (EU 018 and EU 034). This limit was added because the facility uses H2SO4 for DDGS pH control as well as for equipment cleaning. H2SO4 is added to the DDGS process as needed, eventually leaving the facility via the feed products. A small fraction of H2SO4 is converted to SO2 by the DDGS drying process. The rate of conversion of H2SO4 to SO2 is affected by dryer temperature, hence the inclusion of the dryer exhaust temperature limits at EU 018 and EU 034.

SV 007 – The Table C VOC retest requirement was removed and a VOC testing requirement at 60-month intervals was added to Table A because the June 2011 SV 007 VOC retest demonstrated compliance with the SV 007 VOC limit. The PM10 testing requirement was revised to testing at 60-month intervals starting June 1, 2011, which is the date of the test that measured PM10 emissions at less than 60% of the applicable limit. The PM and PM2.5 tests trigger date was revised to June 1, 2011 because these pollutants were last tested on that date (although these tests weren’t due until August 2013). A SV 007 process throughput limit to verify if stack testing is conducted at worst case operating conditions was added. The process limit is a DDGS input to EU 037 from DDGS Dryer B (EU 034) limit because the process throughput directly impacts emissions vented to the DDGS cooler fabric filter CE 027 and the emissions from the cooler stack/vent SV 007.

SV 008 - SV 008 (EU 038) DDGS loadout is now limited to the 12-hour period of 6 AM to 6 PM each day due to use of this operating assumption in PM10 and PM2.5 modeling. The 400 tph DDGS loading process


throughput limit is the value used to calculate uncaptured PM10 and PM2.5 emissions used in modeling and therefore, the permit prohibits increasing this limit unless PM10 and PM2.5 remodeling is conducted. Permit 004 required testing at 60-month intervals based on a trigger date of August 6, 2008. However, the Permittee tested SV 008 on June 1, 2011, and therefore the testing trigger date is reset to June 1, 2011. The 60-month test interval is also changed due to the 2011 test results. PM emissions were measured at 0.0031 gr/dscf which is 77.5% of the 0.0040 gr/dscf limit and therefore subject to a 36-month test interval, and PM10 and PM2.5 emissions were measured at 0.0037 gr/dscf which is 92.5% of the 0.0040 gr/dscf limit, and therefore subject to a 12-month test interval.

SV 009 – The SV 009 (EU 040) NOX emission calculations annual PTE is based on 2700 hr/yr operation but EU 040 modeled NOX emissions for the annual NOx NAAQS are based on emissions from 8760 hr/yr of operation so there is no need for a 2700 hr/yr modeling-based operating limit for SV 009.

EU 018 and EU 034 DDGS Dryers - Revised the requirement regarding wet cake feed to dryers and control equipment breakdown (RTO - CE 005). The revisions incorporated CE 028/EU 035 (boiler) as a permitted control option and added language stating wet cake feed to dryers can resume after either control device resumes operation.

EU 035 – Stack testing requirements were revised due to the change of permitted fuel (from coal to natural gas) and the change in the method of operation (from a natural gas-fired boiler to both a boiler and a direct flame afterburner). The testing requirements are changed as follows:

PM10 and PM2.5 Table C re-test requirements were removed because in 2012 the Permittee demonstrated compliance with applicable limits in permit No. 06300025-004 by ceasing coal combustion and re-testing while combusting natural gas.

Removed the notification requirement to the Supervisor of the Risk Evaluation and Air Modeling unit regarding the results of performance tests. This requirement is no longer warranted due to elimination of coal as boiler fuel.

Removed the requirements to test no later than 12/31/2011 for PM and CO emissions (while combusting coal). These requirements were completed and test results were compliant, and repeat testing for these pollutants while the boiler combusts natural gas is not warranted.

Added testing requirements for when EU 035 is operating as a direct flame afterburner (CE 028). The required tests mimic those required under SV 004 for the CE 005 thermal oxidizer. No testing is required for any other pollutants when EU 035 is not operating as CE 028, because EU 035 is natural gas-fired, and NOX is measured by a CEMS (MR 001).

EU 037 – The CE 027 fabric filter requirements were removed from EU 037 because they were also present under subject item CE 027.

EU 048, EU 053, and EU 054 – PER 004 imposed identical requirements for raising the stack heights for these emergency engines to 30 feet above grade, unless modeling was submitted demonstrating a shorter stack would not cause or contribute to an exceedance of any relevant ambient air quality standard (AAQS). The stack extensions were subject to a June 2011 completion date, and if the Permittee elected to employ stacks less than 30 feet above grade, modeling was due in March 2011.

The Permittee did not increase these stack heights because it intended to submit modeling by the applicable deadline. However, the Permittee requested input from the MPCA regarding how to include these emergency engines in the model, and did not receive a final reply from the MPCA until well past the modeling submittal deadline. Regardless, modeling submitted in 2013 for PER 005 showed


compliance with applicable AAQS, so these stack height/modeling requirements were removed from EU 048, EU 053, and EU 054.

EU 048, EU 053, and EU 054 – Added requirement from 40 CFR pt. 63, subp. ZZZZ at 40 CFR § 63.6590(a)(1)(iii) that specifies these engines are existing affected sources located at an area source. However, no additional requirements from pt. 63, subp. ZZZZ (or 40 CFR pt. 60, subps. IIII or JJJJ) were added to the permit for these sources because these engines are not in the scope of this major amendment, and addition of such requirements is not required by Minn. R. 7007.1600, subp. 1(A) because the remaining permit term is less than three years (based on the issuance date of December 16, 2010 of the pt. 70 operating permit No. 06300025-004).

EU 048 and EU 053 – PER 004 provided flexibility for replacement of each engine with an engine of same or lesser emissions, or, an engine with higher emissions if the Permittee obtains the appropriate permit amendment. This requirement was removed because the engines are NO2 emission sources and have short stacks, the total facility NO2 ambient impacts are high based on 2013 modeling for PER 005 (refer to Section 3.2 and Table 6 of this technical support document), and the Total Facility section of permit No. 06300025-005 contains remodeling requirements for changes to modeled parameters for any modeled NO2 emission source at the facility.

EU 052 and EU 055 – These are DDGS storage silos. This equipment was previously classified as insignificant. However, the silos are vented to the DDGS handling fabric filter that is vented to the atmosphere, and therefore, these silos do not qualify as insignificant activities or conditionally insignificant activities and have been added to the permit.

CE 001 Collection Efficiencies, and CE 002, CE 009, and CE 027 Control Efficiencies – The PM, PM10, and PM2.5 collection/control efficiencies were revised to reflect the 99.0% value used in emission calculations. All revised values are equal to or higher than values in PER 004, except for CE 009 PM which changed from 99.3% to 99.0%. It was determined by MPCA staff that revision to the original BACT analysis that produced these values was not warranted because efficiencies (except for CE 009 PM) were increased or remained the same, and the marginal decrease for CE 009 PM control efficiency was insignificant.

CE 003 -Added a requirement for minimum scrubber additive flowrate (5.7 gph) because this plays a role in HAP capture efficiency, along with associated monitoring and recordkeeping. Added control efficiency values for acetaldehyde, acrolein, formaldehyde, and methanol based on values used in emission calculations for these HAPs.

CE 005 – Added a PM2.5 control efficiency requirement equivalent to the value used in emissions calculations. Permit No. 06300025-004 added a SV 004 PM2.5 (BACT-equivalent) emission limit so it appears the CE 005 PM2.5 control efficiency requirement was overlooked during drafting of permit No. 06300025-004. In addition, all control efficiencies were revised to reflect control efficiency values used in emission calculations. All values were increased except PM decreased marginally from 95.4% to 95.0%; it was determined by MPCA staff that revision to the original BACT analysis that produced these values was not warranted because efficiencies (except for PM) were increased, and the marginal decrease for PM control efficiency was insignificant.

CE 027 – Added a PM2.5 control efficiency requirement. Permit No. 06300025-004 added a SV 007 PM2.5 (BACT-equivalent) emission limit so it appears the CE 027 PM2.5 control efficiency requirement was overlooked during drafting of permit No. 06300025-004. The PM2.5 control efficiency value was assumed to be the same as the (99%) PM10 efficiency, and matched the values used n emission calculations.


Fugitive Emissions: FS 001 was renamed from ‘Truck Traffic’ to ‘Paved Road Requirements’ to more accurately reflect the nature of FS 001 requirements. In addition, for this permit action the Permittee re-modeled PM10 and PM2.5 emissions but did not include paved road fugitive PM10 and PM2.5 emissions in the modeling as allowed by the MPCA May 2011 Paved Road Fugitive Particulate Matter modeling memorandum (refer to Attachment 6). The memorandum specifies when fugitive particulate matter emissions can be excluded from modeling, as well as four requirement tiers for facilities that qualify for this exclusion. The facility qualified for the exclusion because it has both an enforceable fugitive dust control plan, and PM10 and PM2.5 impacts were less than the 60%/80% thresholds, respectively. Under the exemption, the facility is subject to the requirements of Tier 3 because the number of daily trucks is at least 200 (assuming all DDGS is shipped out by the same trucks that deliver grain to the facility; if this is not the case then the trucks per day value will be higher than 200), based on the emission calculations information in the ‘Grain & DDGS (Daily-Model)’ worksheet cell C12 (over two hundred grain trucks per day). The FS 001 paved road fugitive dust requirements were updated to reflect the May 2011 memorandum requirements for when fugitive dust from paved roads were not included in modeling. The permit also requires revision of the fugitive dust plan (Appendix IV) so that the plan does not conflict with the revised FS 001 requirements.

FS 002 and FS 003: Uncaptured grain and DDGS handling emissions were traditionally referred to as fugitive emissions. However, these emissions are not fugitive emissions because they can reasonably be captured and vented to a control device. These emission sources are still listed as ‘FS’ sources in the permit (FS 002 and FS 003) but the source description was modified to indicate the emissions are uncaptured and not fugitive.

These grain and DDGS uncaptured emission are included in the facility emission calculations for permitting purposes. Also, although Minn. R. 7011.1005, subp. 3 refers to these uncaptured emissions as fugitive emissions and limits opacity of these fugitive emissions, the uncaptured emissions do not meet the definition of fugitive emissions (at Minn. R. 7005.0100, subp. 11c), however, these uncaptured emissions remain subject to the opacity limits in Minn. R. 7011.1005, subp. 3.

Added requirements in the permit to vent emissions from processes that are controlled, to the associated air pollution control device (except ethanol loadout/CE 010 because this requirement was already in the permit).

The FS 004 equipment in VOC service equipment count was revised, which in turn changed FS 004 emissions data. The Permittee indicated the original permit FS 004 equipment count was an estimate from the building contractor. This estimate was revised when additional equipment was installed due to the permit No. 06300025-004 production increase (from 55 mmgal/yr to 59.9 mmgal/yr). That earlier revised equipment count was determined by the ratio of the increased to existing production limits applied to the number of valves. For the current permit (No. 06300025-005) the available LDAR report was used for calculating the number of each equipment type. The result was an increase in the total component count from 870 to 2340 with the greatest increases attributable to flanges (from 500 to 1777) and light liquid valves (from 300 to 526).

MR 001 – Removed the requirement for notification of MR 001 installation, and requirements for CEMS certification because these have been completed. Also, additional subp. Db NOX CEMS requirements were added, primarily referenced alternate requirements from pt. 75 appendices.


MR 005 was added to the permit and it contains CE 005 RTO combustion chamber temperature monitor requirements.

Finally, the Permittee provided the following description of their corn oil extraction process:

‘The Valicor corn oil extraction system at HLBE separates corn oil from the partially evaporated thin stillage (syrup) that exits the plant's evaporators using disk stack centrifuge technology. The recovered corn oil is then piped to storage. From storage, the corn oil is then loaded to trucks by direct connection. The system has the capability to extract up to 3.117 million gallons of corn oil per year. There may be emissions associated with the corn oil extraction system itself since the system vents (indoors) to prevent pressure build up issues. We consider any emissions to be insignificant because corn oil has a negligible chemical component (non-hazardous, low vapor pressure) and the temperature of the oil is around 200°F or less. For conservatism, tank losses from the fixed roof corn oil storage tank were quantified using the chemical properties of the compound furfural. There are also particulate emissions associated with corn oil tanker truck traffic on haul roads. These emissions were included in the permit application along with emissions from other truck traffic.

2. Regulatory and/or Statutory Basis

New Source Review

The facility is an existing synthetic minor source under New Source Review regulations. Changes authorized by this permit do not change this status.


Greenhouse gas (GHG) emissions are not subject to regulation for the current permit action (permit No. 06300025-005) because none of the non-GHG pollutant increases exceed the NSR major source threshold. This is based on EPA’s July 24, 2014 memorandum for implementing the June 23, 2014 Supreme Court decision in the Utility Air Regulatory Group v. Environmental Protection Agency case. Part 70 Permit Program

The facility is and remains a major source under the Part 70 permit program. New Source Performance Standards (NSPS)

The natural gas boiler EU 035 is subject to NSPS subp. Db ‘Standards of Performance for Industrial-Commercial-Institutional Steam Generating Units’. The boiler has a low heat release of 4,949 Btu/hr-ft3 and construction of the boiler commenced January 8, 2007.

Equipment in VOC service is subject to NSPS subp. VV ‘Standards of Performance for Equipment Leaks of VOC in the Synthetic Organic Chemicals Manufacturing Industry for which Construction, Reconstruction, or Modification Commenced After January 5, 1981, and on or Before November 7, 2006’.

Volatile organic liquid storage tanks are subject to the requirements of NSPS subp. Kb. National Emission Standards for Hazardous Air Pollutants (NESHAP)

The facility has accepted HAP emission limits so that it is a non-major source under 40 CFR pt. 63. Therefore, no major source NESHAPs apply. Emergency engines are subject to 40 CFR pt. 63, subp. ZZZZ. The natural gas-fired boiler (EU 035) is not subject to 40 CFR pt. 63, subp. JJJJJJ because EU 035 meets the definition of a gas-fired boiler at § 63.11237 and § 63.11195(e) states that a gas-fired boiler is not subject to subp. JJJJJJ. Compliance Assurance Monitoring (CAM)

The changes authorized by this permit action do not trigger CAM. This is because the allowed change only involves Other PSEUs, and according to 40 CFR § 64.5(b), CAM applies to Other PSEUs only at Pt. 70 permit reissuance. Environmental Review & Air Emissions Risk Analysis (AERA)

The changes authorized by this permit action do not trigger requirements for environmental review or an AERA. Existing AERA requirements based on EU 035 coal combustion, have been removed or revised accordingly because EU 035 is no longer permitted to combust coal. Environmental Justice

Environmental Justice (EJ) is the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies. EPA has this goal for all communities and persons across the U.S.A. It will be achieved when everyone enjoys the same degree of protection from environmental and health hazards and equal access to the decision-making process to have a healthy environment in which to live, learn, and work.


As part of the permitting process, the MPCA contacts US E.P.A. Region 5 staff to verify if there are any possible EJ issues for facility location that need to be addressed in the permit action. For this project, MPCA staff contacted EPA Region 5 staff who used the draft Environmental Justice Strategic Enforcement Assessment Tool (EJSEAT) to determine EJ is not a concern (04/3/2014 email from Rachel Rineheart; see Attachment 7).

*Location of the requirement in the permit (e.g., EU, SV, GP, etc.). 3. Technical Information 3.1 Potential to Emit Calculations and Emissions Increase Analysis

Attachment 1 to this TSD contains the emission calculations spreadsheet submitted by the Permittee and reviewed and revised by the MPCA. Delta emissions data is revised based on these calculations.

SV 004 and EU 035 Emissions: It is important to note the summary pages in the spreadsheet account for worst case emissions from SV 004 and SV 005/EU 035/CE 028 and do not double count SV 004 and SV 005/EU 035/CE 028 emissions when worst case operating scenario is SV 005/EU 035 operating as CE 028, and CE 005 is not operating. Several pollutants (SO2, CO, VOC, and all single HAPs excluding acetaldehyde, acrolein, and methanol) are worst case in the ‘SV 004 is operating and is EU 035 not


operating as CE 028’ scenario, and the spreadsheet summary page accounts for this scenario. However, Delta does not have the ability to avoid double counting SV 004 and EU 035 emissions, resulting in the Delta facility totals for each pollutant not matching the spreadsheet totals for each pollutant.

SV 009 Flare Emissions: Although though the permit doesn’t restrict flare operation to 2700 hours per year, SV 009 flare emissions were calculated at annual flare operations of 2700 hours (and pilot operation of 6060 hours/year). This is reasonable because at the loading rack capacity of 5600 gallons per minute, the entire permitted 72.25 mmgal/year annual ethanol production denatured with 5% gasoline (75,862,500 gallons per year) could be loaded in approximately 226 hours based on the following:

75,862,500 gals/yr * minute/5600 gals * hr/60 minutes = 225.78 hr/yr In addition, at the actual loading rate of approximately 500 gallons/minute, loading of annual permitted production would take about 2529 hours based on the following:

75,862,500 gals/yr * minute/500 gals * hr/60 minutes = 2528.75 hr/yr 3.2 Dispersion Modeling

Permit No. 06300025-004 required re-modeling of emissions under certain circumstances. Specifically, if the Permittee desired to change any of the modeled PM2.5 or NOX emission sources, the requirement to re-model is triggered. Permit No. 06300025-005 changes some modeled parameters and to comply with the re-modeling requirements, the Permittee made a decision to re-model for all pollutants as part of the permit issuance process.

The modeled emission rates for uncaptured DDGS loadout emissions are based on AP-42 Table 9.9.1-2 feed shipping PM10 emission factor and 95% collection efficiency. The resulting g/s emission rate is conservative (higher) compared to the emission rate measured by the BCES (which resulted in the BCES determined capture efficiency >95%). Due to MPCA concerns about the BCES determination of uncontrolled emission factor, the Permittee elected to take this conservative approach in determining the modeled emission rate for the uncaptured DDGS loadout emissions. Uncaptured PM10 and PM2.5 emissions from DDGS piling (FS 006) in the DDGS storage building were not modeled because these emissions are less than the modeling insignificant activities thresholds in the most current MPCA Air Dispersion Modeling Guidance (July 2014), and according to the July 2014 guidance can be ignored for Title V modeling purposes (modeling conducted for permit No. 06300025-005 is considered Title V modeling under the July 2014 guidance).

Results of the modeling were substantially different than results from the permit No. 06300025-004 modeling, primarily due to the elimination of coal as boiler fuel and removal or shutdown of all coal- and ash-related emission sources. Overall ambient impacts from PM10 and PM2.5 were substantially lower in the modeling for permit No. 06300025-005 compared to those for permit No. 06300025-004. Most notably, the PM2.5 24-hour total impact (from the facility, nearby sources, and background was 34.3 µg/m3 compared to the 35.0 µg/m3 24-hr NAAQS) decreased from 98% of the 24-hr PM2.5 NAAQS to (26.8 µg/m3) 76.6% of the 24-hr PM2.5 NAAQS. However, due to the use of the exclusion allowed by the May 2011 Paved Road Modeling memorandum, revisions were made to the FS 001 requirements and the Permittee is required to update the Appendix IV Fugitive Emissions Control Plan so that it does not conflict with the revised FS 001 requirements. The permit also states that the FS 001 requirements supersede the Appendix IV requirements until the Appendix IV plan is updated.


Requirements for weekly road sweeping and recordkeeping were revised to requirements for daily inspection, and sweeping whenever fugitive dust is observed. The 250 trucks-per-day limit was removed, the daily grain receiving limit was increased from 3888 tons per day (tpd) to 5000 tpd, the straight truck grain delivery limit was increased from 756 tpd to 1000 tpd, and these receiving limits were moved from FS 001 to GP 001 because the limits are to restrict uncaptured emissions from grain receiving and not fugitive dust emissions from paved roads.

Permit No. 06300025-004 contained numerous Title I BACT-equivalent limits and requirements based on an August 2007 Prevention of Significant Deterioration (PSD) permit application (that was the basis for the December 2010 permit No. 06300025-004) to address and resolve backward-looking PSD issues. Many of these limits were originally written as lb/hr limits. As part of this permit action, the Permittee requested increases to some of these lb/hr limits.

To accommodate this request, the relevant lb/hr limits were converted to comparable lb/process unit limits, and the Title I BACT-equivalent citations were revised as described above in Section 1.3 ‘Other Changes’. The original lb/hr limits were increased as requested and the citation for the increased limits is ‘Title I Condition to avoid major source status under 40 CFR § 52.21 and Minn. R. 7007.3000’. This approach is acceptable because the facility changes prompting the limit increase are unrelated to the original changes/construction (that was subject subsequently to backward-looking PSD permitting), the changes will occur when the facility is a PSD non-major source (after the facility was subject to


backward-looking PSD permitting), and, the (converted BACT-equivalent) limits are retained in the permit. 3.4 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.

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 type of monitoring found on similar units elsewhere.

The table below summarizes the monitoring requirements associated with this amendment.

Requirement (rule basis) Monitoring Discussion

Total Facility

Equipment Inventory: Maintain and update a written inventory of all emission units and control equipment that vent through SV 001, SV 002, SV 003, and SV 008. (Minn. R. 7007.0800, subp. 2)

Equipment inventory update on an as-needed basis, and annual reporting of equipment changes

These requirements track pre-authorized equipment changes allowed under SV 001, SV 002, SV 003, and SV 008 and play a role in verification that the facility has not become a major source under New Source Review or 40 CFR pt. 63.

GP 001 Grain unloading and DDGS loading operations restricted to 6 AM and 6 PM daily (Title I Condition: 40 CFR § 52.21(k) and Minn. R. 7007.3000; Minn. R. 7007.0800, subp. 4 & 5)

Recording and maintaining a log of the clock time completion of all grain truck deliveries and all DDGS loadouts

The daily delivery and loadout time period limit is based on modeling assumptions and recording the finish times of each grain receiving and DDGS loadout provides a direct determination of compliance with this requirement.

emissions stack testing due 90 days after any pre-authorized equipment change

Stack testing is necessary and a valid method for verifying compliance with PM, PM10, and PM2.5 emission limits after making a pre-authorized equipment change. Notification is required upon completion of pre-authorized changes to trigger the stack testing requirements.

SV 003 VOC and HAP emissions stack testing (Title I Condition: To avoid major source threshold under 40 CFR § 52.21 and Minn. R. 7007.3000; Title I condition: To avoid major source threshold under 40 CFR § 63.2 and Minn. R. 7011.7000; Minn. R. 7017.2020, subp. 1)

VOC and HAPemissions stack testing due 90 days after any pre-authorized equipment installation

Stack testing is necessary and a valid method for verifying compliance with VOC and HAP emission limits after making a pre-authorized equipment change. Notification is required upon completion of pre-authorized changes to trigger the stack testing requirements.

SV 003 SV 004 SV 007 EU 035/ CE 028

HAP emissions testing (Title I Condition: To avoid major source threshold under 40 CFR § 63.2 and 7011.7000; Minn. R. 7017.2020, subp. 1)

Routine periodic HAP emissions stack testing currently at 36-month intervals

Routine periodic testing is necessary and the preferable method for determining compliance with single HAP (acetaldehyde, acrolein, formaldehyde, and methanol) limits.

CE 003 CO2 Fermenta-tion Scrubber

Scrubber Additive Flow Rate: Greater than or equal to 5.7 gph; Acetaldehyde, Acrolein, Formaldehyde, and Methanol: > 98% control efficiency (Title I Condition: to avoid major source threshold under 40 CFR § 63.2 and Minn. R. 7011.7000)

Daily monitoring and recordkeeping of additive flow rate

The scrubber liquid additive (sodium bisulfite) enhances HAPs collection efficiency. Therefore monitoring the additive injection rate to the scrubber water provides an indication of compliance for HAP emissions.

*Location of the requirement in the permit (e.g., EU, SV, GP, etc.). 3.5 Insignificant Activities

Heron Lake BioEnergy, LLC has several operations which are classified as insignificant activities under the MPCA’s permitting rules. These are listed in Appendix III to the permit. No new insignificant activities are associated with this permit amendment. 3.6 Permit Organization

In general, the permit meets the MPCA Delta Guidance for ordering and grouping of requirements. One area where this permit deviates slightly from Delta 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 Table A or B of the permit. The main reason is that the appendices are word processing documents 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.

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 where will be further unit-specific requirements later). This is the case for the requirements at GP 001 (Grain Receiving and DDGS Loadout). 3.7 Comments Received

Public Notice Period: <start date> - <end date> EPA 45-day Review Period: <start date> - <end date> 4. Permit Fee Assessment

Attachment 3 to this TSD contains the MPCA assessment of Application and Additional Points used to determine the permit application fee for this permit action as required by Minn. R. 7002.0019. The permit action includes one major amendment permit application (4640), and four administrative amendment applications (3380, 3528, 3694, 3771) all received after the effective date of the fee rule (July 1, 2009).

Additional points apply to the major amendment changes due to: 1) establishment of HAP limits and requirements to avoid the pt. 63 major source threshold; 2) revision of the ethanol production limit (which is used to avoid NSR and pt. 63 major source status); and, 3) revision of NSPS subp. Db applicable requirements due to the boiler fuel change. Additional point fees do not apply to the administrative amendment changes. This permit action also includes two re-openings (4399 and 4907) for CE 003 operating parameters based on 2012 and 2014 stack testing that do not incur additional point fees. 5. Conclusion

Based on the information provided by Heron Lake BioEnergy, LLC, the MPCA has reasonable assurance that the proposed operation of the emission facility, as described in the Air Emission Permit No. 06300025-005 and this TSD, will not cause or contribute to a violation of applicable federal regulations and Minnesota Rules.

Note: - VOC emissions estimates are conservative assuming all truck loading/unloading emissions possess denaturant vapor characteristics. - Emissions are shown at 100% from both rail and truck loading scenarios in order to demonstrate emissions from both scenarios. However, truck loading is considered worst-case and is used to represent emissions from this source in order to avoid double-counting.


TRUCK and RAIL LOADING HAP LOSSES:Major Air Permit Amendment

Emission Factor Basis: - HAP emissions based on mass fraction of total VOC emissions (see previous page). - Truck HAPs based on typical MSDS for unleaded gasoline (mid points used). Only listed MSDS HAPs are included.

- Truck HAP calculation assumes that trucks that load ethanol previously contained gasoline and gasoline vapors will be sent to flare for control during ethanol loading.

Emergency Firewater Pump IC Engine:Major Air Permit Amendment

Emission Factor Basis: - Engine is diesel fueled. - NOx, CO, VOC and PM Emission factors based on NSPS Subpart IIII, Table 4 for a 300 HP engine. - Emission Factor for PM10 and PM2.5 assumed to be all PM emissions.

- Potential restricted emissions based on 100 non-emergency hours of annual operation. - Engine will only operate from 12:00 PM to 4:00 PM (non-emergency), 7 days a week. - VOC emission factor considered conservative as it includes total organic compounds (TOC). - HAPs assumed to be negligible. - NOx emissions were calculated by multiplying the "NMHC+NOx" emission factor by 76% based upon the linear relationship of NOx to NMHC from Table 1 of Subpart IIII, Table 1 from 40 CFR 89.112, to Tables 4, 5, and 6 from 40 CFR 1039.102. - Similar to NOx emissions, VOC emissions were determined by multiplying the "NMHC+NOx" factor by 24%. This emission factor is considered conservative since it includes total non-methane hydrocarbons.

Paved Haul Roads:Major Air Permit Amendment

Emission Factor Basis: - PM/PM10/PM2.5 emission factors based on AP-42 Section 13.2.1 (January 2011). - PM/PM10/PM2.5 calculations assume 100% of all materials are transported by truck. However, HLBE uses rail service for grain, DDGS, & ethanol. - Calculations are based on 100% of DGS being shipped wet, which requires more trucks to transport (based on weight).

- Grain density = 56 lb/bushel. - Vehicles travel approximately 1/2 full and 1/2 empty. - Vehicle miles traveled (VMT) is dependent on material delivered or shipped. - Additional traffic from employee and visitor vehicles were estimated at less than 0.1%, and therefore emissions are considered negligible and not included.

AP-42 13.2.1.3 Predictive Emission Factor Equation:

E = k (sL) 0.91 x (W) 1.02

Where:k PM 0.011 particle size multiplier (dimensionless)

k PM10 0.0022 particle size multiplier (dimensionless)k PM2.5 0.00054 particle size multiplier (dimensionless)

sL 1 Road surface silt loading (g/m2)W 27.5 Average truck weight (tons) - 40 tons full/15 tons empty.

Attachment 6 - May 2011 MPCA Paved Road Modeling Policy Memorandum

DEPARTMENT: POLLUTION CONTROL AGENCY SF-00006-05 (4/86)

STATE OF MINNESOTA

DATE: 5/16/11Office Memorandum

TO: Interested Parties

FROM: Chris Nelson Manager, Strategic Projects Sector Industrial Division

PHONE: 651-757-2603

SUBJECT: Air Quality Policy on Paved Roads and Fugitive Particulate Matter

The Minnesota Pollution Control Agency (PCA) has updated its policy on air dispersion modeling for particulate matter (PM) and paved road fugitive dust. The policy will maintain adequate control of paved road fugitive PM at industrial facilities while allocating air modeling and permitting resources to other projects or issues of environmental and PCA priority, thereby improving overall environmental and program outcomes. The policy applies to new facilities and physical expansions at existing facilities.

Policy

Under specific circumstances, the PCA will no longer require the inclusion of paved road fugitive PM emissions in air quality modeling analyses that support air quality permitting or environmental review. The policy covers modeling for both particulate matter less than 10 microns (PM10) and 2.5 microns (PM2.5). For comparisons with National or Minnesota Ambient Air Quality Standards, those circumstances include instances where a modeling analysis demonstrates that:

• predicted ambient impacts (modeled + background concentrations) equal less than 95% of the applicable PM10 and PM2.5 standards, and the facility air permit contains an appropriate and enforceable fugitive dust control plan or comparable permit conditions; or

• predicted ambient impacts (modeled + background concentrations) equal less than 60% of the applicable PM10 and 80% of the applicable PM2.5 standard. Requirements in Minn. R. 7011.150 to prevent avoidable PM from becoming airborne apply.

For comparisons with federal Prevention of Significant Deterioration increments, those circumstances include instances where a modeling analysis demonstrates that:

• predicted ambient impacts (net modeled concentrations) equal less than 75% of the applicable PM10

standard and 80% of the applicable PM2.5 standard, and the facility air permit contains an appropriate and enforceable fugitive dust control plan or comparable permit conditions; or

• predicted ambient impacts (net modeled concentrations) equal less than 35% of the applicable PM10

and 40% of the applicable PM2.5 standard. Requirements in Minn. R. 7011.150 to prevent avoidable PM from becoming airborne apply.

Exceptions will be determined on a case-by-case basis by PCA Risk Managers. Potential reasons for exceptions include public complaints about fugitive dust or indications that the policy will lead to significant increases in PM emissions from non-fugitive sources. There may also be instances where modeling for Prevention of Significant Deterioration increments may deviate from the policy. This policy does not affect quantification of fugitive PM for the purposes of permit or other rule applicability. Air quality modeling supporting permitting in maintenance areas or development of State Implementation Plans is not affected.

To implement this policy, a small team with representation from the air modeling and air permitting groups drafted a general paved road fugitive PM control plan that can be attached to or incorporated into an air permit. The plan is based on known best practices and existing requirements to keep paved roads clear of silt, spilled commodities, and other debris through regular visual inspections and maintenance. Air modeling staff will update PCA guidance documents as appropriate to reflect the policy.

Paved Road Fugitive Dust Permit Conditions

AQ REGUIREMENTS GUIDE

Paved Road Fugitive Dust – Applicability, Requirements Explanation of Tiers Guidance on use of Tier Help Files Screen Guidance:

The Tier approach and help file language is approved for permits that completed modeling with predicted ambient impacts (modeled + background concentrations), without the inclusion of paved road fugitive emissions, in the following ranges: 1) NAAQS predicted ambient impacts between 60-95% of the PM10 standard and 80-95% of the PM2.5 standard, or 2) PSD increment predicted ambient impacts between 35-75% of the PM10 standard and 40-80% of the PM2.5

standard.

If the facility’s predicted ambient impacts for NAAQS or PSD increment are greater than the above ranges for PM2.5 and PM10, the facility needs to remodel and include a paved road fugitive emissions source group in air quality modeling analyses which will likely result in facility-specific permit conditions.

If the facility’s predicted ambient impacts are less the above ranges for PM2.5

and PM10, there is no need to require paved road fugitive permit conditions. Exceptions will be determined on a case-by-case basis by Risk Managers. Potential reasons for exceptions include public complaints about fugitive dust or indications that the policy will lead to significant increases in PM emissions from non-fugitive sources.

Enter these requirements at the total facility level of the permit under the Source-Specific Requirements header.

Overview of Tiers Screen Guidance:

Tier 1. Low likelihood of paved road fugitive dust. For example, the facility’s paved surface traffic is limited to employee parking and minimal third party truck traffic, it is unlikely that traffic would track dirt from a nearby unpaved surface to the paved surfaces, and it is unlikely that dust would be generated from products hauled by trucks. As needed corrective actions.

Tier 2. Moderate likelihood of paved road fugitive dust. For example, the facility’s paved surface traffic is limited to employee parking and moderate third party truck traffic (approx. less than 100 vehicles per day), it is possible that traffic would track dirt from a nearby unpaved surface to the paved surfaces, or it is possible that dust could be generated from products hauled by trucks with open beds. Weekly inspections, corrective actions, and recordkeeping.

Tier 3. High likelihood of paved road fugitive dust. For example, the facility’s paved surface traffic has high levels of third party truck traffic (approx. more than 100 vehicles per day), it is likely that traffic would track dirt from a nearby unpaved surface to the paved surfaces, or it is likely that dust could be generated from products hauled by trucks with open beds. Daily inspections, water/chemical application, speed limit, and recordkeeping.

Tier 4. Case-by-case requirements to supplement Tier 3 requirements as needed.
