1.2 Facility Description

REG Albert Lea, LLC (REG) is a biodiesel manufacturing plant located near Albert Lea, Minnesota.

The facility currently produces biodiesel from soybean oil and methanol, but after the

construction and installation of the equipment authorized by this permit action, the facility will

be able to handle lower quality feedstocks as well. After the upgrade, the biodiesel facility will

have the capacity to produce 31,500,000 gallons of biodiesel per year.

The facility is a minor source of emissions for particulate matter (PM), particulate matter less

than ten microns (PM10), particulate matter less than 2.5 microns (PM2.5), nitrogen oxides (NOx),

sulfur dioxide (SO2) and carbon monoxide (CO) and a synthetic minor for volatile organic

compounds (VOCs) and methanol (a federally‐designated Hazardous Air Pollutant, HAP). The

main sources of methanol emissions are expected to be equipment leaks and the distillation

process. Six emission sources and four storage tanks will be controlled by a flare for VOC and

HAP emissions.


The facility currently processes soybean oil into biodiesel. After the installation of the

equipment described in this permit action, the facility will be able to process low quality

feedstocks such as used cooking oil, inedible corn oil, and lower quality animal fats.

For low quality feedstocks, the process will start with pre‐treatment of the feedstock to remove

metals, phosolipids, proteins, and other impurities using a filter of diatomaceous material and a

centrifuge. The feedstock is then sent to a deacidification column where the feedstock is heated

up rapidly in order to separate out water and fatty acidsfrom the triglycerides.

From the deacidification column the feedstock is sent to a number of reactors and decanters

which are collectively referred to as the transesterification process. Methanol is added to react

with the feedstock and sodium methylate is added as a catalyst. This chemical process converts

triglyceride and methanol into biodiesel and glycerin.

After the transesterification reaction, hydrochloric acid is added to the biodiesel to neutralize

the pH.

The next step in the process is to recover the unreacted methanol. This is accomplished with a

methanol rectification column, a feedstock absorber and a water absorber. The recovered

methanol is recycled back and used again in the transesterification process.

Once the methanol is removed from the biodiesel, the biodiesel is sent to the biodiesel

distillation wipe‐film evaporator (WFE) (EU009) for final processing. From the distillation WFE

the biodiesel is sent to storage and loadout.

Vapors from the transesterification process (EU001), the nitrogen blanket (EU002), biodiesel

loadout (EU003), acidulation (EU005) and biodiesel distillation (EU009) as well as vapors from

the methanol and sodium methylate tanks are vented to the flare.

Other tanks on site are used for feedstock, free fatty acid, soapstock and biodiesel storage.

There are 12 low vapor pressure tanks at the facility used for storage purposes.

Throughout the biodiesel production process there is nitrogen (in gas form) in the headspace of

the reactors. This is called the nitrogen blanket (EU002). Nitrogen is used because of its low

reactivity and flammability properties.

Additionally, REG buys steam from POET Biorefining – Glenville East (POET) for the purpose process

thermal energy and heating buildings. This averages to about 12.5 mmbtu/hr of energy which is a small


portion of POET’s boiler capacity. When POET’s boilers go down for maintenance, REG takes that

opportunity for maintenance.

1.3 Description of the Activities Allowed by this Permit Action

This permit action includes a major amendment, a minor amendment and an administrative amendment.

For the major amendment, REG proposes to modify the existing transesterification system by installing

new vessels in the reactor/decanter series. The goal is to increase reaction residence time to achieve a

more complete reaction from triglyceride and methanol to fatty acid methyl esters (biodiesel).

This project will allow the facility to operate at a consistently high processing rate while maintaining

product quality. New vessels will be aspirated to the existing methanol recovery and ultimately the

existing emission control system (vacuum pump vented to SV001 which is controlled by a flare, CE001).

Due to the fact that the existing methanol recovery system is handling saturated methanol vapors, no

change is expected in hourly vent emissions. However, this project is adding additional equipment which

will be subject to NSPS subp. VV‐a and a marginal increase in fugitive VOC (methanol) is expected due to

increased equipment count in methanol service.

For the minor amendment, REG is installing a free fatty acid (FFA) stripping system, a biodiesel distillation system, and thermal fluid heaters at the facility. The FFA stripping system will allow REG to use lower quality feedstock to produce high quality biodiesel. The FFA stripper will remove these impurities before the biodiesel process begins.

The biodiesel distillation system will improve the separation of biodiesel from co‐products.

The thermal fluid heaters will distribute thermal energy to the aforementioned equipment. The heaters are rated at 36 million BTU per hour (18 MMBtu/hr each) and burn only natural gas.

The administrative amendment is for a change in ownership. The REG Albert Lea, LLC purchased the facility from Soymor LLC on July 7th, 2011.

The language 'This is a state‐only requirement and is not enforceable by the U.S. Environmental

Protection Agency (EPA) Administrator and citizens under the Clean Air Act' refers to permit

requirements that are established under state law rather than by the federal Clean Air Act. The language

is to clarify the distinction between permit conditions that are required by federal law and those that

are established under state law. State law requirements are not enforceable by the EPA or by citizens

under the federal Clean Air Act, but are fully enforceable by the MPCA and citizens under provisions of

state law.

3. Technical Information

Limit to avoid classification as a major source under NESHAP

The Permittee is required to operate a flare to control single HAP and total HAP emissions in order to

avoid major source status under NESHAP. The limit in the permit is for methanol, which is both a VOC

and a HAP. Minn. R. 7011.0070 specifies that flares achieve a 98% control efficiency for VOCs. Since

methanol is both a VOC and a HAP, the 98% control efficiency from Minn. R. 7011.0070 applies. By

achieving 98% control efficiency for methanol, total HAP emissions are inherently below the major

source threshold of 25 tons per year and therefore no limit is needed.

The requirement to operate the flare is listed in the permit under GP003. Additional requirements for

the flare are listed under CE001.

Limit to avoid requirement to complete environmental review

The threshold in Minn. R. 4410.4300, subp. 5(A) for when a mandatory Environmental Assessment

Worksheet (EAW) is an increase of 25,000 dry tons or more per year of input. The feedstock received by

REG contains water and the actual weight of the dry feedstock is not directly measured. Therefore, the

limit to avoid the requirement to conduct an EAW restricts biodiesel production to an increase of 6.5

million gallons per year. The facility is now limited to 31.5 million gallons per year of biodiesel

production (the facility was previously permitted at 25 million gallons per year of biodiesel production).

Using the density of biodiesel (7.35 pound per gallon), the amount of feedstock needed to produce 6.5

million gallons of biodiesel can be calculated as follows:

6,500,000 ∗ 7.35 ∗ 1 2000 23,887.5

From the equation above, an increase of 6.5 million gallons per year in biodiesel production requires less

than 25,000 tons per year of additional feedstock which is the limit for when an EAW is required.


Attachment 4 to this TSD contains the determination letter sent by the MPCA to REG stating that an

EAW is not required at this time.

The limit to avoid the requirement to complete environmental review is listed in the permit under

GP003.

Applicability of NSPS subp. NNN and NSPS subp. RRR

The transesterification process (EU001) has equipment that is subject to both NSPS subp. NNN and NSPS

subp. RRR. The process stream from EU001 is sent to EU009 (biodiesel distillation), which is also subject

to NSPS subp. NNN. From 40 CFR §60.700(c)(5), the equipment in EU001 that is subject to NSPS subp.

RRR is subject only to the requirements of 40 CFR § 60.705(r).

3.1 Calculations of Potential to Emit (PTE)

Attachment 1 to this TSD contains detailed emission calculation spreadsheets and supporting information prepared by the MPCA and the Permittee.

FS001 PTE

This source contains all the equipment subject to NSPS VV‐a, including equipment that was subject to NSPS VV. To reduce regulatory complexity, the facility is choosing to comply with subp. VV‐a for all equipment leaks.

The EPA document Protocol for Equipment Leak Emission Estimates (11/95) was used in determining the PTE for the equipment subject to NSPS VV‐a. The following emission factors (EF) were used:

* Where SV is the screening value in ppmv.

The facility used a screening value of 200 ppmv. The facility measured concentrations around 50 ppmv from the equipment leaks and applied a factor of safety of 4 to arrive at 200 ppmv.

EU006 Deacidification

Emissions for this unit were determined using the following equation:


200 ∗ 1000 1000000 ∗ 46 ∗ 60 ∗ 0.075

29.87

Where:

Flow rate of unit = 200 dscf

Concentration of ethanol (EtOH) = 1000 ppm

Molecular weight of EtOH = 46 g/mol

Density of air at standard conditions = 0.075 lb/scf

Molecular weight of air at standard conditions = 28.97 g/mol

GP002 (EU007 and EU008) Hot Oil Heaters

Emission factors from AP‐42 Chapter 1.4 and 40 CFR pt. 98, subp. A were used to calculate the PTE of these emissions. A factor of 1000 was used to convert EFs from lb/MMscf to lb/MMBtu.

EU009 Biodiesel Distillation

Emissions were calculated using chemical engineering software by Pfaudler Engineered Systems. . The inputs to this program are not public data. Myron Danzer, the General Manager of REG (legally responsible official), certified that the values obtained for VOC and methanol emissions are correct.

EU010 Cooling Tower 2

Emissions for this unit were calculated using emission factors from a similar facility with a capacity of 12 million gallons per year. A safety factor of 1.5 was applied to the emission factors. VOC and HAPs emissions for this unit were determined using the following equation:

3 ∗ 0.07% ∗ 31.512 ∗ 60 ∗ 1.5 ∗

32006000

Where:

Liquid loss rate = 3 lb/hr

Maximum Methanol (MeOH) concentration = 0.07%

Ratio of plant capacities = 31.5 mmgal REG /12 mmgal similar facility

Safety factor = 1.5

Ratio of cooling tower flow rates = 3200 gpm/6000 gpm

EU011 Water Absorber

Emissions for this unit were calculated using the following equation:


501000000 ∗ 32 ∗ 1000 ∗ 60 ∗ 0.075

28.97

Where:

MeOH concentration = 50 ppm

Molecular weight of MtOH = 32 g/mol

Density of air at standard conditions = 0.075 lb/scf

Molecular weight of air at standard conditions = 28.97 g/mol

3.3 Periodic 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 kind of monitoring found on similar units elsewhere.

The table below summarizes the periodic monitoring requirements for those emission units for which

the monitoring required by the applicable requirement is nonexistent or inadequate.

at 31.5 million gallons/year of biodiesel production

(previously permitted for 25 million, this permit

action allows for an additional 6.5 million gallons of

biodiesel production per year which corresponds to

an increase of 23,887.5 dry tons/year of feedstock).

Maintenance of daily production records and

monthly calculation of the 12‐month rolling sum is

sufficient to demonstrate compliance with this limit.

*Where the requirement appears in the permit (e.g., EU, SV, GP, etc.).

3.4 Insignificant Activities

REG has several operations which are classified as insignificant activities under the MPCA’s permitting

rules. These are listed in Appendix B to the permit.

The permit is required to include periodic monitoring for all emissions units, including insignificant

activities, per EPA guidance. The insignificant activities at this Facility are only subject to general

applicable requirements. Using the criteria outlined earlier in this TSD, the following table documents

the justification why additional periodic monitoring is or is not necessary for the current insignificant

activities.

The Facility is located outside the Metro area and has paved parking lots and unpaved roads used for loading and unloading.

3.5 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 sections and are not part of the electronic tracking system. Violation of the appendices can be enforced, but the computer system will not automatically generate the necessary enforcement notices or documents. Staff must generate these.

Another discrepancy in ordering and grouping of requirements is that GP003 is used to list facility wide

limits. The units that are affected by the limits are listed in the group. The requirement to operate a flare

to control HAPs is listed at GP003; the requirements for how the flare is to be operated are listed at

CE001.

3.6 Comments Received

Public Notice Period: January 25, 2013 – February 25, 2013

EPA 30‐day Review Period: January 25, 2013 – February 25, 2013

Comments were not received from the public during the public notice period.


The revised permit was sent to EPA for their 30‐day review on January 25, 2013. Comments were not

received from EPA during their review period.

4. Permit Fee Assessment

Attachment 3 to this TSD contains the MPCA’s assessment of Application and Additional Points used to

determine the permit application fee for this permit action as required by Minn. R. 7002.0019. The

permit action includes three permit applications, all received after the effective date of the rule (July 1,

2009). The permit includes the incorporation of requirement from three different NSPS that were

triggered by the modification authorized by the permit action. The permit action also includes

incorporation of requirements from a fourth NSPS, however this was an existing standard that is being

incorporated into the permit and was an applicable standard when the unit began construction.

Therefore, it is not a chargeable activity.

5. Conclusion

Based on the information provided by REG Albert Lea, LLC, the MPCA has reasonable assurance that the

proposed operation of the emission facility, as described in the Air Emission Permit No. 04700061‐002

and this TSD, will not cause or contribute to a violation of applicable federal regulations and Minnesota

Rules.

REG Applicability Determination Letter

August 23, 2012 Mr. Douglas P. Judge, P.E. Senior Manager Environmental Compliance and Services Renewable Energy Group 416 South Bell Avenue PO Box 888 Ames, IA 50010‐0888 Re: Determination of Applicability for Environmental Review – Proposed Fuel Conversion

Expansion Project (Glenville), Renewable Energy Group (REG) Dear Mr. Judge: The Minnesota Pollution Control Agency (MPCA) has received your request for an applicability determination on the need for an Environmental Assessment Worksheet (EAW) for the proposed expansion of an existing fuel conversion facility. The project described in your letter would expand the REG biodiesel production facility in Glenville, Minnesota, to enable the processing of low quality feedstock, such as use cooking oil, inedible corn oil, and lower quality animal fats to produce additional biodiesel. You have noted that the previous (Soymor) EAW on the existing facility described a project for the production of 25 million gallons per year (MGY) of biodiesel. You also indicated that the design rate for the proposed expanded facility would be 31.5 MGY, for an increase of 6.5 MGY. Based on the conversion factor you provided (7.35 lbs/gallon), this would require processing of an additional 23,887.5 tons of additional feedstock per year. Therefore, the project you described would not exceed the threshold of 25,000 tons per year for the preparation of an EAW pursuant to Minn. R. 4410.4300, subp. 5A, and an EAW would not be required for this expansion project. In addition, as communicated to you previously, the mandatory EAW requirement in Minn. R. 4410.4300, subp. 10B, relating to the construction of storage tanks for the feedstock noted above, does not apply in that the types of materials to be stored do not meet current definitions of hazardous materials. Similarly, the EAW requirement in Minn. R. 4410.4300, subp. 15 will not apply so long as the requested increase in air emissions does not result in an increase of 250 TPY or more in the potential to emit for any single air pollutant. Please be aware that all such determinations are provisional and subject to revision if the review of permit applications you have submitted results in an increase in the estimated capacity to 25,000 or more tons of feedstock per year or if other key information changes. Please note also that this letter does not address any requirements related to air permitting, which will be handled via separate communication from staff in the MPCA air permitting program.

Mr. Douglas P. Judge, P.E. Page 2 August 23, 2012
