6. Project Description:

a. Provide the brief project summary to be published in the EQB Monitor, (approximately 50 words).

Al-Corn Clean Fuel (Al-Corn) proposes to expand its dry-mill ethanol production facility located in Claremont, Minnesota (Facility). Al-Corn is proposing to expand its Facility to increase ethanol production from 50 million gallons per year (MMGY) to 130 MMGY of 200-proof ethanol (Project). The Project will result in an increase of corn throughput to 47 million bushels per year (MMBu/year), and an increase in water appropriations by 200 MMGY, which will result in a total water appropriation of 400 MMGY.


b. Give a complete description of the proposed project and related new construction, including infrastructure needs. If the project is an expansion include a description of the existing facility. Emphasize: 1) construction, operation methods and features that will cause physical manipulation of the environment or will produce wastes, 2) modifications to existing equipment or industrial processes, 3) significant demolition, removal or remodeling of existing structures, and 4) timing and duration of construction activities.

Al-Corn owns the existing Facility located south of State Highway 14, approximately one mile west of the city of Claremont (City) in Dodge County as shown on Figure 1. The Project will occur within the Facility’s current footprint and three undeveloped parcels of agricultural land owned by Al-Corn immediately west of the existing Facility. The Facility’s pre-construction site layout is provided in Figure 2, and the post-construction layout is provided in Figure 3. Al-Corn’s Facility currently produces 50 MMGY of 200-proof ethanol with a corn throughput of approximately 18 MMBu/year. The Facility also produces 132,000 tons per year (tpy) of dried distillers grains and solubles (DDGS) and 1.6 MMGY of corn oil. The Project will increase the Facility’s production capacity to 130 MMGY of 200-proof ethanol, 350,000 tpy of DDGS, and nearly four MMGY of corn oil. The Project will enable the Facility to increase production by increasing its corn processing capacity to approximately 47 MMBu/year. Al-Corn’s Facility currently includes grains receiving and milling equipment, cook and fermentation equipment, distillation and drying equipment, DDGS storage and loadout equipment, ethanol storage and loadout equipment, and power generators. The existing equipment is included in the list provided in Attachment 1. The Project will include installing a new natural gas combustion turbine with a duct burner for combined heat and power, replacing and relocating grain storage and handling equipment, expanding rail loading/unloading capabilities, adding equipment for additional fermentation, distillation, and product storage, and adding one new natural gas fired boiler and new DDGS dryer. The Project will also include installation of the following: a new wet scrubber to control volatile organic compounds (VOCs) and hazardous air pollutants from fermentation equipment; fabric filters and centrifugal collectors to control PM, PM10, and PM2.5 emissions from grain handling equipment; one new regenerative thermal oxidizer (RTO) to control VOCs, hazardous air pollutants, and carbon dioxide emissions; and a new flare to control VOC emissions from the ethanol loading rack. A list of all equipment to be added, modified, removed, or repurposed is provided in Attachment 1. Al-Corn has two existing stormwater ponds at the Facility. The Project will expand the existing stormwater pond south of the Facility to allow additional stormwater treatment. Al-Corn will also construct three new stormwater ponds along the proposed rail loop, two in the southwest corner of the loop and one in the northwest corner of the loop. A total of six wetland basins were identified within the Project area. Al-Corn anticipates approximately 0.30 acres of wetland impacts as a result of the Project.


The proposed railroad loop for the expanding rail loading/unloading capabilities is oval shaped with three parallel tracks and will occupy previously undeveloped land west of the Facility. The EPCO Carbon Dioxide Products Inc. facility (EPCO Facility), currently owned by Air Products, is co-located with the Al-Corn Facility. EPCO will cease operations and Al-Corn will dismantle and remove the equipment at the EPCO Facility as part of the Project.

Al-Corn anticipates beginning construction of the Project after completion of environmental review and obtaining all necessary permits and approvals, possibly in early 2017. Al-Corn expects construction of the Project will last from 18 to 22 months.

d. Explain the project purpose; if the project will be carried out by a governmental unit, explain

the need for the project and identify its beneficiaries. The purpose of the Project is to increase production of ethanol and its co-products, DDGS and corn oil, by increasing the amount of corn throughput. The Project also adds rail transportation for shipping ethanol and corn oil, which are currently shipped only by truck.

e. Are future stages of this development including development on any other property planned or likely to happen? o Yes X No

If yes, briefly describe future stages, relationship to present project, timeline and plans for environmental review.

f. Is this project a subsequent stage of an earlier project? X Yes o No If yes, briefly describe the past development, timeline and any past environmental review.

The Facility was constructed in 1996. In 2001, the MPCA completed an EAW for Al-Corn’s proposed increase in ethanol production from 19.25 MMGY to 30 MMGY. In 2004, Al-Corn increased the production rate to 34.9 MMGY through process efficiency and equipment optimization. In 2006, the MPCA completed an EAW for Al-Corn’s proposed facility expansion and increase in ethanol production from 34.9 MMGY to 50 MMGY. Between 2012 and 2015, Al-Corn proposed a 10 MMGY ethanol production increase related primarily to process efficiency, which would have taken production from 50 MMGY to 60 MMGY. The production increase did not require additional corn throughput. In consultation with


the MPCA in 2015, Al-Corn agreed to incorporate the previously proposed 10 MMGY ethanol production increase into Al-Corn’s air permit application for the Project. The Project includes this past 10 MMGY production increase request.

Al-Corn submitted an aboveground storage tank (AST) permit application on December 24, 2015, and an air permit application on December 30, 2015, for installation of a new 120,000 gallon ethanol day tank. On January 19, 2015, Minnesota Pollution Control Agency (MPCA) Environmental Review staff reviewed the 120,000 gallon ethanol day tank proposal and determined that it was not a connected or phased action in relation to the current Project because the current Project was determined to not be substantially certain to proceed at the time of the AST application. The MPCA authorized construction of the tank and issued the AST permit on March 16, 2016.

7. Cover Types: Estimate the acreage of the site with each of the following cover types before and

after development:

9. Land Use:

a. Describe: i. Existing land use of the site as well as areas adjacent to and near the site, including

parks, trails, prime or unique farmlands. The Facility is located on a 40-acre rural parcel south of US Highway 14, west of the City. The Project will occur on Al-Corn owned land within and adjacent to the Facility as shown on Figure 1. The existing railroad runs east/west along the south edge of the Facility. The surrounding land is used for crop production. The nearest receptor is a residence located southwest approximately 2,200 feet from the existing thermal oxidizer. This residence is approximately 450 feet south of the railroad along the south central side of the Facility. Adjacent land uses will remain the same. No impacts will occur to parks or trails. Al-Corn referenced the Natural Resources Conservation Service (NRCS) Web Soil Survey, NRCS electronic Field Office Technical Guide (eFOTG), and the Dodge County Soil Survey to determine if there was any prime and unique farmland, or any farmland of statewide and/or local importance within the Project area. Soils designated by the NRCS as prime farmland, prime farmland if drained, and farmland of statewide importance located within the Project area or within the surrounding vicinity are shown on Figure 5. Coordination with the NRCS is typically required to assess impacts to farmland. However, in this case the areas impacted by the Project are currently under Al-Corn ownership. Therefore, the farmlands impacted by the Project are not subject to the Farmland Protection Policy Act, and Al-Corn is not required to coordinate with the NRCS to assess any impacts to the areas under its ownership.

ii. Plans. Describe planned land use as identified in comprehensive plan (if available) and

any other applicable plan for land use, water, or resources management by a local, regional, state, or federal agency.

The Project is consistent with all government planned uses for the area. The Project includes utilizing some of the Al-Corn owned agricultural farmland area for a railroad loop, spur, and stormwater ponds. The existing Facility will connect to the new rail loop with minor modifications. Al-Corn will convert the existing township road dividing the parcels of agricultural land to agricultural land and land for the rail loop. Al-Corn will seek approval from Claremont Township for removal of the road following completion of the environmental review process.


iii. Zoning, including special districts or overlays such as shoreland, floodplain, wild and scenic rivers, critical area, agricultural preserves, etc. The Project area is zoned as agricultural and industrial.

b. Discuss the project’s compatibility with nearby land uses, zoning, and plans listed in Item 9a

above, concentrating on implications for environmental effects.

The Project is compatible with nearby land uses and zoning. Land taken out of agricultural production for the new rail loop and pond will be partially offset with the conversion of the township road into agricultural land. After construction of the rail loop and spur, the agricultural land within the loop will still be capable of agricultural production.

c. Identify measures incorporated into the proposed project to mitigate any potential

incompatibility as discussed in Item 9b above.

Not applicable. 10. Geology, Soils and Topography/Land Forms:

a. Geology - Describe the geology underlying the project area and identify and map any susceptible geologic features such as sinkholes, shallow limestone formations, unconfined/shallow aquifers, or karst conditions. Discuss any limitations of these features for the project and any effects the project could have on these features. Identify any project designs or mitigation measures to address effects to geologic features. The Facility and the Project area are located in the physiographic province often designated as the Rochester Till Plain (Wright, 1972). The Rochester Till Plain generally extends across the southeastern corner of Minnesota east of the city of Owatonna and south of the St. Paul-Minneapolis metropolitan area. The Rochester Till Plain is a nearly featureless surface of pre-Wisconsinian glacial till dissected by tributaries of the Mississippi River. Near the Facility and Project area, the undulating surface of the till plain has been extensively farmed. Across the Rochester Till Plain, the major tributaries of the Mississippi River mark the most significant relief. In the vicinity of the Facility and Project area, relief is marked by the undulating surface of the till plain and intermittent streams. The topography near the Facility and Project area is rolling with elevations near 1,280 feet. The topography north of the Facility and Project area gently slopes northward toward the South Branch Middle Fork Zumbro River, while the topography south of the Facility and Project area gently slopes southward toward Dodge Center. Facility and Project area topography is displayed on Figure 4 - Topographic Map. Surficial deposits at the Facility and Project area are approximately 125 feet thick and consist of a thin layer of loam textured till deposited during pre-Wisconsin age (Lusardi et al., 2002). The surface is highly oxidized and the till is locally deeply leached. Locally, the till is mantled by Des Moines Lobe outwash adjacent to and south of Judicial Ditch No. 7 approximately one half mile to the south of the Facility and Project area. Based on mapped soil units and driller’s logs for wells in the area, the till varies in composition from clay loam to sandy loam. Driller’s logs for the test well and the Al-Corn wells indicate that the till is oxidized to a yellow or yellow-brown


color very deep, as anticipated, to depths of 23 to 64 feet. The till has low permeability but contains sand seams that locally can yield small quantities of water to domestic and other private wells. The depth to bedrock in the area in and around the Facility and Project area ranges from 120 to 130 feet. Based on Al-Corn’s review of geologic mapping and karst mapping inventory conducted by the Minnesota Geological Survey (Tipping et. Al., 2004), no springs or sinkholes associated with karst are present in this area of Dodge County; given the depth to bedrock, future formation of karst features are unlikely. Relief of the bedrock surface is relatively low in this area. The upper approximately 1,300 to 1,400 feet of bedrock in the area consists of marine sedimentary rocks of Early Paleozoic age.

b. Soils and topography - Describe the soils on the site, giving NRCS (SCS) classifications and descriptions, including limitations of soils. Describe topography, any special site conditions relating to erosion potential, soil stability or other soils limitations, such as steep slopes, highly permeable soils. Provide estimated volume and acreage of soil excavation and/or grading. Discuss impacts from project activities (distinguish between construction and operational activities) related to soils and topography. Identify measures during and after project construction to address soil limitations including stabilization, soil corrections or other measures. Erosion/sedimentation control related to stormwater runoff should be addressed in response to Item 11.b.ii.

Al-Corn used the NRCS Web Soil Survey to assess existing soil resources within the Facility and Project area. Based on the Soil Survey for Dodge County, the following soils are found within the Facility and Project area: Maxcreek silty clay loam (L180A), Blooming silt loam (L183B), Newry silt loam (L182A), and Warsaw loam (L190B) as shown on Figure 5. These soils have topsoils ranging from silty clay loam to silt loam. The majority of the soils onsite are well drained or moderately well drained. The Facility and Project area is located within soils that have been previously disturbed during construction of the original facility and previous expansions, and it is not anticipated that the soils would exhibit the original profile. The soil characteristics for the Facility and Project area provide a low saturated hydraulic conductivity and generally low susceptibility to wind and rill or sheet erosion. The topography of the Project area is generally flat (See Figure 4). Construction of the Project will result in the disturbance of existing ground cover, which will result in some potential for erosion. Al-Corn will obtain coverage under the MPCA’s general NPDES/SDS Construction Stormwater Permit and implement Project area-appropriate requirements. Al-Corn must develop and implement a Stormwater Pollution Prevention Plan (SWPPP). Al-Corn will utilize temporary soil stabilization techniques during Project construction and will follow erosion prevention and sediment control requirements in accordance with its SWPPP. Al-Corn will permanently stabilize disturbed soils after Project construction using vegetation or will return the land to agricultural production. Approximately 280,000 cubic yards of soil will be excavated over a 60.3 acre area. Al-Corn will re-use approximately 135,000 cubic yards of this soil for the Project and will stockpile, seed, and vegetate all excess soil on-site. No soil is expected to be brought in and no excavated soil will be removed from the Project area.


Al-Corn reviewed well log information obtained from the Minnesota Department of Health (MDH)-County Well Index (CWI) and determined shallow groundwater is located approximately 30-40 feet below the ground surface of the Facility and Project area. Existing and proposed secondary containment will not be at or below the recorded groundwater level.

11. Water Resources: a. Describe surface water and groundwater features on or near the site in a.i. and a.ii. below.

i. Surface water - lakes, streams, wetlands, intermittent channels, and county/judicial ditches. Include any special designations such as public waters, trout stream/lake, wildlife lakes, migratory waterfowl feeding/resting lake, and outstanding resource value water. Include water quality impairments or special designations listed on the current MPCA 303d Impaired Waters List that are within one mile of the project. Include MDNR Public Waters Inventory number(s), if any.

No surface water features located within one mile of the Facility are designated as public waters, trout stream/lake, wildlife lakes, migratory waterfowl feeding/resting lake, or outstanding resource value waters. The Facility straddles the boundary between the upper South Branch Middle Fork Zumbro River and Judicial Ditch No. 7 (Havana Ditch) to Dodge Center Creek, in the Zumbro River watershed. Rice Lake is located over 2.5 miles northwest of the Facility and outlets toward the east into the South Branch Middle Fork Zumbro River located two miles north of the Facility. Judicial Ditch No. 7 is located approximately one mile south of the Facility. The downstream impairments on the 2014 impaired waters list include E. coli, mercury, and PCBs as well as: · Dodge Center Creek, Assessment Unit: 07040004-592, Turbidity TMDL approved · Zumbro River, Middle Fork, South Branch,Assessment Unit: 07040004-525, Turbidity TMDL

approved · Zumbro River, Middle Fork, Assessment Unit: 07040004-519, Turbidity listing; no TMDL at

this time · Lake Zumbro, Phosphorus listing; no TMDL at this time · Zumbro River, Assessment Unit: 07040004-501, Turbidity TMDL approved

The draft 2016 impaired waters list also includes these impairments: · Dodge Center Creek, Assessment Unit: 07040004-988, Both fish and macroinvertebrates

indices of biologic integrity (IBI) · Dodge Center Creek, Assessment Unit: 07040004-989, Macroinvertebrates IBI · Zumbro River, Middle Fork, South Branch, Assessment Unit: 07040004-978,

Nutrients/eutrophication · Zumbro River, Middle Fork, South Branch, Assessment Unit: 07040004-976,

Macroinvertebrates IBI

Judicial Ditch No. 7 may be a source for both nitrogen and phosphorus pollutants to Dodge Center Creek. Rice Lake is likely reducing overall riverine water clarity and impacting aquatic biological stream communities downstream.


ii. Groundwater – aquifers, springs, seeps. Include: 1) depth to groundwater; 2) if project is within a MDH wellhead protection area; 3) identification of any onsite and/or nearby wells, including unique numbers and well logs if available. If there are no wells known on site or nearby, explain the methodology used to determine this. Natural Resource Group completed a well inventory in 2008. Al-Corn updated this information in 2015. The updated well inventory, including MDH well logs, is included as Attachment 2. Information on wells located at the Facility and Project area is summarized in Table 1 below. Al-Corn’s review of the CWI indicates the Al-Corn Facility and Project area are located outside of the designated Drinking Water Supply Management Area situated primarily west and south of the City. The following wells were identified within a three-mile radius of the Facility: 85 active domestic wells, two municipal community supply wells (city of Claremont), one industrial well, three sealed and eight active abandoned wells, two active monitoring wells, six active public supply/non-community transient wells, four active public supply/non-community/non-transient wells, one sealed public supply/non-community well, three active, one inactive, and one unknown status commercial wells, one unknown status and two abandoned unspecified use wells, and four unknown use and status wells. (Attachment 2) Al-Corn has eight wells on-site including five commercial wells, one inactive domestic well and two monitoring wells. There are five wells screened within the Dubuque-Galena aquifer. Three of these wells are used for pumping (Map ID 3, 4 and 5); one is an inactive well to be capped as part of the Project (Map ID 2); and one is a monitoring well (Map ID 1). One commercial well and one monitoring well are screened in the Prairie du Chien-Jordan aquifer (Map ID 7 and 8). One inactive domestic well is screened in the Dubuque-Galena aquifer (Map ID 6). MDH assigns unique IDs to describe wells in the public atmosphere. Al-Corn uses an additional set of internal IDs for day-to-day practices.

The map IDs in Table 1 above correspond with the well inventory map in Attachment 2. Surficial deposits at the Facility and Project area are approximately 125 feet thick and consist of a thin layer of loam textured till deposited during pre-Wisconsin age (Lusardi et al., 2002). Locally, the till is mantled by Des Moines Lobe outwash adjacent to and south of


Judicial Ditch No. 7 approximately one half mile south of the Facility. Based on data collected for Facility on-site wells, the water table is approximately 285 to 295 feet below ground surface. Shallow groundwater is located approximately 30-40 feet below ground surface. The till deposits generally have low permeability but do contain sand seams that can yield small quantities of water to domestic and other private wells. However, based on information presented in the CWI (Attachment 2), no domestic wells were identified, with screens drawing water from Quaternary aquifers, within a half-mile of the Facility and Project area.

The upper approximately 1,300 to 1,400 feet of bedrock in and around the Facility and Project area consist of marine sedimentary rocks of Early Paleozoic age. The bedrock hydrostratigraphy described in Runkel et al. (2003) separates groundwater flow in the upper bedrock units into two aquifer systems: The Upper carbonate aquifer or Dubuque-Galena Group is separated from the Prairie du Chien-Jordan aquifer system by the Decorah-Platteville-Glenwood confining unit. The St. Lawrence confining unit, which underlies the Jordan sandstone, separates these aquifer systems from the deeper sedimentary bedrock aquifers. Both the City and Al-Corn currently utilize the Dubuque-Galena Group as a water supply; however, the four Al-Corn industrial wells include one well (Map ID 8) screened within the Prairie du Chien-Jordan aquifer system that will be added for water appropriation as part of the Project. Al-Corn’s four industrial wells will be utilizing water from both the Dubuque-Galena Group and Prairie du-Chien-Jordan aquifers following completion of the Project.

b. Describe effects from project activities on water resources and measures to minimize or

mitigate the effects in Item b.i. through Item b.iv. below.

i. Wastewater - For each of the following, describe the sources, quantities and composition of all sanitary, municipal/domestic and industrial wastewater produced or treated at the site.

1) If the wastewater discharge is to a publicly owned treatment facility, identify any pretreatment measures and the ability of the facility to handle the added water and waste loadings, including any effects on, or required expansion of, municipal wastewater infrastructure.

2) If the wastewater discharge is to a subsurface sewage treatment systems (SSTS), describe the system used, the design flow, and suitability of site conditions for such a system.

3) If the wastewater discharge is to surface water, identify the wastewater treatment methods and identify discharge points and proposed effluent limitations to mitigate impacts. Discuss any effects to surface or groundwater from wastewater discharges.

Sanitary Wastewater There are two existing sanitary mound systems at the Facility permitted by Dodge County. One system services the Al-Corn Facility and was built in 1996 and modified in 1998. The other system, built in 2002, currently services the EPCO Facility. Al-Corn will dismantle the EPCO sanitary mound system and construct a new sanitary mound system to service the sanitary facilities constructed on the southeastern portion of the Facility as part of the Project. Al-Corn will construct the new sanitary


mound system in accordance with the county permitting and regulatory requirements. See Figure 6 for the locations of the existing and proposed sanitary mound systems. Industrial Wastewater There will be no authorized discharges from the Facility other than stormwater. Al-Corn reuses the Facility’s process and non-process water in the Facility’s production of DDGS and corn oil, or releases it as a water vapor plume. A water balance diagram for the existing Facility is included as Figure 7. Process and non-process water make-up is needed to replace evaporated water lost primarily from the cooling tower and the DDGS dryers as depicted in the Facility water balance diagram. Al-Corn combines concentrated minerals, other solid matter from the process, and the make-up water with the DDGS produced at the Facility.

The Project will require additional make-up water for the process scrubber, new cooling tower and energy center that will include a new natural gas-fired combined cycle turbine, duct burner and boiler. Al-Corn will continue to discharge only stormwater from the Facility following completion of the Project. The water balance for the Facility following completion of the Project is included as Figure 8.

ii. Stormwater - Describe the quantity and quality of stormwater runoff at the site prior to

and post construction. Include the routes and receiving water bodies for runoff from the site (major downstream water bodies as well as the immediate receiving waters). Discuss any environmental effects from stormwater discharges. Describe stormwater pollution prevention plans including temporary and permanent runoff controls and potential BMP site locations to manage or treat stormwater runoff. Identify specific erosion control, sedimentation control or stabilization measures to address soil limitations during and after project construction.

Pre-Construction Stormwater Stormwater-only runoff from the Facility currently drains to four main areas as shown on Figure 9.

1) Southwest drainage area: This area drains to a culvert under the existing railroad in the southwest corner, flows south under the railway to Judicial Ditch No. 7, and on to Dodge Center Creek.

2) Northwest drainage area: This area drains to a wetland in the northwest corner, then to culverts north under US Highway 14, to ditch drainage flowing through a series of ditches flowing north to the South Branch Middle Fork Zumbro River.

3) Northeast drainage area: This area drains to a stormwater pond in the northeast corner, then to culverts north under US Highway 14, to ditch drainage flowing through a series of ditches flowing north to the South Branch Middle Fork Zumbro River.

4) Southeast drainage area: This area drains to a culvert under the existing railroad in the southeast corner, flows south under the railway to Judicial Ditch No. 7, and on to Dodge Center Creek.


Post-Construction Stormwater After completion of the Project, stormwater-only runoff from the Facility will still drain to the same four locations as pre-construction. As the Project will create additional impervious surface and incorporate additional land, Al-Corn will expand the existing stormwater pond south of the Facility to allow additional stormwater treatment. Al-Corn will also construct three new stormwater ponds along the proposed rail loop, two in the southwest corner of the loop and one in the northwest corner of the loop. Al-Corn has designed all stormwater ponds with pond outlet structures to slowly discharge stormwater runoff. This will minimize the amount of sediment that is discharged from the stormwater ponds. Al-Corn believes the new stormwater ponds will improve stormwater quality over existing conditions.

Al-Corn will annually inspect all stormwater ponds, remove sediment from the ponds as needed, and dispose of sediment in accordance with MPCA regulations. Al-Corn has designed the new stormwater ponds so the post-development runoff rate is less than the pre-development runoff rate for the 2-, 10-, and 100-year storm event. Based on Al-Corn’s review of pre-construction site conditions in comparison to post-construction site conditions, the Project will decrease the overall volume and flow rate of stormwater at the Facility and Project area. Table 2 below shows the stromwater volume and flow changes.

Al-Corn has tested containment area stormwater prior to discharge for Total Suspended Solids (TSS) and observed an average of 39.8 mg/L from the sampling events of 2014 and 2015. The new stormwater ponds will provide more stormwater retention volume than the existing stormwater ponds. The MPCA National Pollutant Discharge Elimination System (NPDES/SDS) permit for the Facility will limit these discharges to 30 mg/L TSS, ensuring that these discharges do not contribute to existing downstream water quality impairments related to TSS/turbidity. The NPDES/SDS permit discharge limits for carbonaceous biochemical oxygen demand (CBOD) will also help to ensure that these discharges do not contribute to downstream impairments related to low dissolved oxygen. The MPCA believes that phosphorous may be elevated in the discharges from the stormwater ponds in comparison to the downstream phosphorus water quality criteria; the MPCA also believes the installation and management of the new stormwater ponds as well as implementation of best management practices (BMPs) will help minimize phosphorus concentrations in the discharges from the Facility and Project.

iii. Water appropriation - Describe if the project proposes to appropriate surface or groundwater (including dewatering). Describe the source, quantity, duration, use and purpose of the water use and if a MDNR water appropriation permit is required. Describe any well abandonment. If connecting to an existing municipal water supply, identify the wells to be used as a water source and any effects on, or required expansion of, municipal water infrastructure. Discuss environmental effects from water appropriation, including an assessment of the water resources available for appropriation. Identify any measures to avoid, minimize, or mitigate environmental effects from the water appropriation.

Al-Corn currently holds an active Minnesota Department of Natural Resources (MDNR) water appropriation permit (1995-5160) originally issued in 1995. Under the current permit, Al-Corn is authorized to withdraw up to 200 MMGY from four existing wells (Map ID 2, 3, 4, and 5 shown in Attachment 2 and listed in Table 1 under Item 11) at a pumping rate not to exceed 400 gallons per minute (gpm). Well Map ID 2 is capped. Al-Corn withdraws the water from the shallow Dubuque-Galena Group aquifer. The Project will allow the Facility to expand ethanol production, which increases the need for water. Al-Corn will use an existing well (Map ID 8) at the Facility, not currently used for production and screened within the deeper aquifer (Prairie du Chien-Jordan), to support the increased ethanol production as well as provide a back-up to existing water supply wells screened in the shallower Dubuque-Galena Group. Well Map ID 8 was installed in 2008; the MDNR has previously reviewed and approved Al-Corn’s pump test plan. The Aquifer Test Report prepared for this well by Natural Resources Group, LLC (June 6, 2008) for the former Claremont Renewable Energy, LLC, is on-file with the MDNR. Based on Al-Corn and MDNR’s analysis of the pump test results, the aquifer parameters were favorable for development with transmissivity estimates varying from 17,000 to 20,000 ft2/day and aquifer storage coefficient estimates varying from 0.00010 to 0.00017. Based on the aquifer test data and the analysis results, Well Map ID 8 is capable of sustaining a yield in excess of 700 gpm without long-term depletion of the groundwater resource. Al-Corn will submit an application to MDNR requesting an amendment to their current permit by utilizing well Map ID 8 and increasing the amount of permitted water withdrawal to a total of 400 MMGY, which is an increase of 200 MMGY over the currently permitted withdrawal of 200 MMGY. Given that no nearby wells utilize the Prairie du Chien-Jordan aquifer, Al-Corn believes that sustained pumping at Well Map ID 8, at less than 700 gpm, will not result in any water use conflict with the overlying Dubuque-Galena Group aquifer, and the pumping influence of the well will not significantly affect the operation of other existing water supply wells. Existing hydrogeologic data and data collected for the aquifer test indicates that there is a very strong hydraulic separation between the deeper Prairie du Chien-Jordan aquifer system and the overlying Dubuque-Galena Group aquifer. Regional mapping of the potentiometric surfaces of the Prairie du Chien-Jordan aquifers indicates that ground water in this aquifer in the area of the Facility and Project is not within the ground-watershed of any surface water bodies in Minnesota. Because the Prairie du Chien-Jordan aquifer system, in which the production well is completed, is physically


separated from the shallow aquifers by a confining unit, after completion of the Project, Al-Corn’s pumping from the Prairie du Chien-Jordan aquifer at the Facility would not affect the hydrology of nearby surface-water features.

iv. Surface Waters a) Wetlands - Describe any anticipated physical effects or alterations to wetland features

such as draining, filling, permanent inundation, dredging and vegetative removal. Discuss direct and indirect environmental effects from physical modification of wetlands, including the anticipated effects that any proposed wetland alterations may have to the host watershed. Identify measures to avoid (e.g., available alternatives that were considered), minimize, or mitigate environmental effects to wetlands. Discuss whether any required compensatory wetland mitigation for unavoidable wetland impacts will occur in the same minor or major watershed, and identify those probable locations. Rebecca Beduhn, a Wetland Delineator (#2143) certified by the University of Minnesota and the Minnesota Board of Water and Soil Resources (BWSR) conducted a wetland delineation on July 31, 2015. This field review was conducted in conjunction with a Crop Slide Analysis to properly identify, delineate and classify the wetlands located within the Facility and Project area. Local regulatory agencies (MPCA, MDNR, BWSR, USACE, and various Dodge County officials) reviewed the Project area on November 3, 2015. A total of six wetland basins were identified within the Project area as listed on Table 3 below and shown on Figure 10. Al-Corn anticipates the Project will result in approximately 0.30 acres of wetland impacts. The impacts to Wetland 5 and Wetland 6 are a result of the construction of the rail loop. Al-Corn considered design alternatives such as changes to the rail loop profile and design curves that would avoid and minimize impacts. Minimizing wetland impacts for the Project remains difficult due to the location of the wetlands adjacent to the existing railroad. The current rail loop plan avoids impacts to Wetland 4 by minimizing the curve radius. Table 3 below further details the wetland characteristics and impacts. All jurisdictional wetland areas in the Project area are protected by state and federal law and impacts are only allowed through a permitting process involving Dodge County, the MPCA, the MDNR, U.S. Army Corps of Engineers (USACE) and BWSR. Al-Corn will mitigate any approved impacts through the purchase of wetland credits from an USACE or BWSR approved wetland bank in the same major watershed as the Project.

1 Size includes areas of wetland within the area of investigation only. Wetlands may extend beyond the limits of the area investigated and actual wetland size may be larger than that indicated. 2 The northeast and southeast ponds are counted in the pre-construction wetland acreage because the ponds met the characteristics of a wetland. The ponds are referred to as wetland 1 and 2 in the wetland delineation report. The post-construction wetland acreage does not include the northeast and southeast ponds. The post-construction stormwater pond acreage includes the previously existing northeast pond and the modified southeast pond.

b) Other surface waters- Describe any anticipated physical effects or alterations to

surface water features (lakes, streams, ponds, intermittent channels, county/judicial ditches) such as draining, filling, permanent inundation, dredging, diking, stream diversion, impoundment, aquatic plant removal and riparian alteration. Discuss direct and indirect environmental effects from physical modification of water features. Identify measures to avoid, minimize, or mitigate environmental effects to surface water features, including in-water Best Management Practices that are proposed to avoid or minimize turbidity/sedimentation while physically altering the water features. Discuss how the project will change the number or type of watercraft on any water body, including current and projected watercraft usage.

Wetlands are the only surface water present within the Facility and Project area. Other surface waters (streams, ditches, etc.) will not be physically impacted by the Project. Al-Corn will construct three new stormwater ponds and modify the existing southeast storm water pond to increase its size. The existing pond will continue to operate throughout Project construction, and function in the same manner after Project construction.

12. Contamination/Hazardous Materials/Wastes: a. Pre-project site conditions - Describe existing contamination or potential environmental

hazards on or in close proximity to the project site such as soil or ground water contamination, abandoned dumps, closed landfills, existing or abandoned storage tanks, and hazardous liquid or gas pipelines. Discuss any potential environmental effects from pre-project site conditions that would be caused or exacerbated by project construction and operation. Identify measures to avoid, minimize or mitigate adverse effects from existing contamination or potential environmental hazards. Include development of a Contingency Plan or Response Action Plan.

Short Elliot Hendrickson Inc. (SEH), a consultant for Al-Corn, reviewed the MPCA’s “What’s in My Neighborhood?” website1 listings within the Facility and Project area. A copy of SEH’s review is

included in Attachment 3. Two spills previously occurred at the Facility. A spill of 1,500 gallons of denatured ethanol was released to gravel when meters malfunctioned during bulk truck loading on March 26, 1997. The MPCA investigated and closed this spill investigation on April 9, 1997. A second spill occurred on September 24, 1997, with 1,500 gallons of ethanol released when an above ground storage tank was overfilled. The ethanol was released into a containment area with some entering a stormwater holding area. The stormwater holding area egress was diked and three (3) water samples were collected. A technical memorandum prepared by RUST Environment & Infrastructure, dated December 1, 1997, detailed the soil sampling that followed the September 1997 spill to identify any remaining contamination associated with the release. RUST collected four soil samples from six to eight inches below ground surface in the containment area. Samples were analyzed for benzene, cyclohexane, n-hexane, and pentane and concentrations detected were below established Soil Reference Values. The MPCA closed the site investigation on August 28, 2001. There are no records of any other petroleum spills at the Facility.

In the event Al-Corn encounters contaminated soil during construction, they will handle the soil according to a Construction Contingency Plan (CCP) to be developed by the construction contractor prior to the start of construction. The CCP will provide staff training and implementation requirements for the handling and disposal of regulated materials if encountered during construction activities.

b. Project related generation/storage of solid wastes - Describe solid wastes generated/stored

during construction and/or operation of the project. Indicate method of disposal. Discuss potential environmental effects from solid waste handling, storage and disposal. Identify measures to avoid, minimize or mitigate adverse effects from the generation/storage of solid waste including source reduction and recycling.

Project construction activities will generate temporary waste consisting of typical construction debris, including wood and cardboard shipping materials. Al-Corn’s contractors will dispose of the wastes in an approved solid waste construction/demolition landfill facility in accordance with city, county, state, and federal regulations. Facility operations generate less than 12 cubic yards per week of municipal solid waste, which is and will continue to be collected by the local licensed garbage hauler on a weekly basis. Al-Corn does not expect the amount of solid waste generated by the Facility to change significantly after completion of the Project.

c. Project related use/storage of hazardous materials - Describe chemicals/hazardous materials

used/stored during construction and/or operation of the project including method of storage. Indicate the number, location and size of any above or below ground tanks to store petroleum or other materials. Discuss potential environmental effects from accidental spill or release of hazardous materials. Identify measures to avoid, minimize or mitigate adverse effects from the use/storage of chemicals/hazardous materials including source reduction and recycling. Include development of a spill prevention plan.

The Facility produces ethanol in an enclosed area (both manufacturing process and material handling). Because the Facility material handling and manufacturing process equipment are enclosed, the potential for stormwater contamination by contact with significant materials is


limited. After completion of the Project, all Facility material handling and manufacturing processes will continue to be enclosed. In most cases, potential effects to the environment through contact with significant materials would only be possible in the event of a spill, leak, or equipment failure. Fuel could be present to contaminate stormwater in the event of a mishap in fueling vehicles in the Facility yard or in the event of a spill or leak of liquid ethanol or denaturant gasoline. Spills or leaks of fuel or finished material in the Facility tank farm area are captured within the containment dikes. Finished material spills at the Facility loadout area or from liquid transfer are minimized by the Facility spill prevention procedures and bulk transfer policy. Due to the relatively low saturated hydraulic conductivity of the soils in the Project area, the potential for spills contaminating the ground water, if responded to properly, is minimized. The Facility’s rail and existing truck loading areas are equipped with drain pans on the floors to collect any spills. These drain pans are connected to pipes that route spills to a 2,000-gallon holding tank in the Facility tank containment area. This holding tank will collect small spills without discharging into the main containment area. If a larger spill occurs, the holding tank will overtop and spill into the containment area where spilled materials are held until reused for processing, or managed by off-site disposal with a certified waste disposal contractor, at the discretion of the Al-Corn plant manager. The Distillation, Dehydration and Evaporation (DDE) area of the plant has an 18” concrete curb surrounding the area. A section of the curb is 4” lower to ensure that if during a fire event, fire protection water is directed to a specific area. The capacity of the containment is sized to contain 110% of the largest vessel volume plus rainfall. The containment volume is 57,600 gallons indicating a depth of 11” --- that leaves an additional 3” of containment volume before the overflow weir is reached. The largest vessel has a volume of 26,000 gallons. Secondary containment is displayed in Figure 11 with additional information in Table 4, below.

Stormwater from the Facility’s ethanol loadout and truck loadout area will be collected in the drain pans and flow by gravity via drain pipes into the secondary containment area. This water, along with rain that falls directly into the containment, is captured in the secondary containment area. There is a drain pipe with a valve on it that connects the containment area to the stormwater pond located south of the Facility. This valve will remain closed at all times until the stormwater is tested prior to discharge to the Facility’s stormwater pond. Prior to discharge of stormwater from the containment area, a representative grab sample is collected and analyzed in the Facility’s laboratory for ethanol by High Performance Liquid Chromotagraphy (HPLC) and also checked for other indicators of contamination such as discoloration, oil sheen, unusual odor or appearance. If there is no evidence of contamination, the sump pumps are activated and the stormwater is discharged to the stormwater pond. Water with evidence of impacts will be managed by re-use in the process, or managed by off-site disposal with a certified waste disposal contractor, at discretion of the Al-Corn plant manager. Al-Corn has 29 existing above ground regulated and non-regulated storage tanks (ASTs) in multiple tank containment areas. These tanks store corrosion inhibitor, sulfuric acid, 50% sodium hydroxide, fermentation, corn oil, alpha amylase, gluco amylase, liquid urea, thin stillage, current syrup, dryer syrup, NH3, cookwater, beer, 200 proof ethanol, 190 proof ethanol and denaturant. The new tanks proposed as part of the Project will increase the Facility’s tank storage volume. The location of the existing storage tanks and the proposed new tanks are shown on Figure 11. A list of existing and proposed tanks is provided in Attachment 4.


In accordance with provisions in the Spill Prevention Control and Countermeasure (SPCC) Plan, AST permit, and air permit for the Facility, Al-Corn must inspect the ethanol and denaturant storage tanks and containment areas on a regular basis to proactively identify leaks or material defects. In the event of a tank failure within a secondary containment area, the containment areas are sized to hold 110% of the largest tank volume plus rainfall. Al-Corn will recover any spilled material contained within the secondary containment area for reprocessing or proper disposal according to state and federal regulations. See Table 4 below for secondary containment information.

Secondary containment for spills inside of the processing buildings is provided by a curb (approximately 6” high) located around the interior perimeter of the buildings at the base of the wall. The curb facilitates drainage to the buildings drains and sumps, which are then pumped to a number of process vessels. Al-Corn must keep a copy of its current SPCC Plan for the Facility on-site as required by Federal rules, 40 CFR Part 112. Al-Corn will amend the SPCC Plan to include the new tanks. The SPCC Plan must include a spill contingency plan, secondary containment including berms and dikes, drainage systems, procedures for managing above-ground tanks, maintenance of AST integrity, mechanical integrity of piping, pumps and valves, the Facility transfer operations, site security, personnel training and maintenance of records.

d. Project related generation/storage of hazardous wastes - Describe hazardous wastes

generated/stored during construction and/or operation of the project. Indicate method of disposal. Discuss potential environmental effects from hazardous waste handling, storage, and disposal. Identify measures to avoid, minimize or mitigate adverse effects from the generation/storage of hazardous waste including source reduction and recycling.

Al-Corn generates used oil during Facility operations. The used oils are not regulated as hazardous waste, but are sent back to the manufacturer for re-processing. Facility process/operations generate hazardous waste including solvents from a parts washer and laboratory waste. Al-Corn labels and stores hazardous waste in the laboratory located in the Facility’s main process building. Al-Corn disposes of the hazardous waste through the Olmsted County Hazardous Waste Program. Al-Corn is a very small to minimal quantity generator (VSQG) of hazardous waste, generating less than 220 pounds or 22 gallons per month. Al-Corn will not generate new or substantially increase the amount of hazardous wastes generated due to the Project.


13. Fish, Wildlife, Plant Communities, and Sensitive Ecological Resources (rare features): a. Describe fish and wildlife resources as well as habitats and vegetation on or in near the site.

Wildlife observed at the Facility includes whitetail deer, turkeys, and migratory birds. Areas at the Facility and Project area considered suitable for wildlife habitats are limited to the large wetland complex (Wetland 4), located in the northwest corner of the Project area. This wetland is classified as a seasonally flooded basin and does not contain large amounts of open water, and therefore is not a significant waterfowl attractant. The majority of the Facility property is, and after completion of the Project will remain in, active row crop agricultural production (corn and soybean), which wildlife does utilize. The Facility stormwater-only runoff discharges to the north and south. To the south, these discharges enter Judicial Ditch No. 7 (Havana Ditch) to Dodge Center Creek to the South Branch of the Middle Fork of the Zumbro River. To the north, the Facility discharges enter an unnamed ditch tributary to the South Branch of the Middle Fork of the Zumbro River, upstream of the Dodge Center Creek confluence.

The fish community in Judicial Ditch 7 is dominated by species tolerant to degraded aquatic conditions, including brook stickleback, white sucker and central mudminnow. Upstream of Judicial Ditch 7, the aquatic macroinvertebrates in Dodge Center Creek are dominated by taxa commonly found in wetlands. The lower reach of Dodge Center Creek is dominated by macroinvertebrates tolerant of high TSS levels. The fish community in the South Branch of the Middle Fork of the Zumbro River, downstream of the facility north stormwater discharge, is dominated by fathead minnow, common shiner, sand shiner, white sucker, green sunfish and creek chub, and also includes largemouth bass, blackside darter and longnose dace. Downstream of the Dodge Center Creek confluence, the South Branch of the Middle Fork of the Zumbro River fish community is dominated by white sucker, green sunfish, creek chub, fathead minnow and sand shiner, and also includes northern hogsucker and golden redhorse.

b. Describe rare features such as state-listed (endangered, threatened or special concern) species,

native plant communities, Minnesota County Biological Survey Sites of Biodiversity Significance, and other sensitive ecological resources on or within close proximity to the site. Provide the license agreement number (LA-722_) and/or correspondence number (ERDB _____________) from which the data were obtained and attach the Natural Heritage letter from the MDNR. Indicate if any additional habitat or species survey work has been conducted within the site and describe the results.

The existing railroad runs east/west along the south edge of the Facility and Project area and contains strips of prairie habitat with the potential for prairie species. Portions of this habitat may be impacted by fill to connect the existing railroad with the proposed rail loop. SEH contacted the U.S. Fish and Wildlife Service for Section (USFWS) 7(a)(2) guidance on threatened and endangered species. The USFWS provided an Information, Planning and Conservation System (IPaC) Trust Resource Report (IPaC Report) to Al-Corn on August 31, 2015.


The IPaC Report identified Prairie Bush-clover (Lespedeza leptostachya) and the Northern Long-eared bat (Myotis septentrionalis) as endangered species that are within close proximity to the Facility and Project area.

The MDNR queried its Natural Heritage Information System Database (NHIS Database) to determine if known occurrence of rare plants, animals, or unique features have been identified in the Facility and Project area. The NHIS Database identified several potential species within the Facility and Project area. Plants listed in the NHIS Database include Eryngium yuccifolium (Rattlesnake master, special concern), Valeriana edulis var. ciliate (edible Valerian, state-threatened), and Oxypolis rigidior (Cowbane, watchlist). These plants are referred to as the target species. Although all three are listed by the state of Minnesota, only Valerian is legally protected.

MDNR state-listed plant species considered rare are a potential occurrence in the Project area, as they have been documented to be present within remnant prairie associated with railroad and road right of ways. Potential habitat to support these rare species is potentially present along the existing railroad corridor, and along the Township Road 110th Avenue right of way. Potential habitat is limited to remnant unmaintained areas within railroad and township road right of way. The majority of the Project area is currently used for row crop agriculture, and likely does not contain suitable habitat to support state-listed botanical species.

A botanical survey was completed by SEH on June 27, 2016, following approval by the MDNR to proceed with the proposed survey methodology. The botanical survey identified a number of individual species present in the Project area. All of the target species were positively identified, and were present in the anticipated locations along the railroad and township road right of way. Al-Corn submitted the botanical survey results to the MDNR in a memorandum dated July 6, 2016, for review and concurrence of the. The MDNR provided concurrence of the survey findings on August 5, 2016. This concurrence is specific to the identification of Valerian, as it is the sole protected species identified. The botanical survey and MDNR’s response are provided in Attachment 5.

A total of 10 individual Valerian plants were identified within the Project area. Although the survey extended slightly past the anticipated limits of the rail expansion, no other Valerian plants were observed. The Valerian plants are found in two locations, and are associated with occurrences of the other two target plant species (Rattlesnake-master and Cowbane). Permission to take (permanently remove) Valerian is required by the MDNR prior to impact. Al-Corn has initiated a request for an Endangered and Threatened Species Taking permit, which may require an appropriate mitigation strategy, with the MDNR.

Rare animals that were identified within one mile of the Project area include Blanding’s turtle and creek heelsplitter. Rare animals are likely not a concern, as habitat to support their occurrence, namely emergent wetland for the Blanding’s turtle, and riverine systems for the mussel, are not present in the Project area.

c. Discuss how the identified fish, wildlife, plant communities, rare features and ecosystems may be affected by the project. Include a discussion on introduction and spread of invasive species from the project construction and operation. Separately discuss effects to known threatened and endangered species.


There are no known identified fish communities or rare features and ecosystems identified within the Project area. Wetlands 5 and 6 are wooded basins surrounded by agricultural land and will be impacted by the proposed rail loop. The wildlife species observed and/or expected to use the agricultural fields or wooded wetlands are mobile and will ultimately move to other locations, within or nearby the Project area. Al-Corn will take steps to ensure no invasive species are introduced during construction activities. Al-Corn will re-vegetate disturbed areas with an appropriate seed mixture that is invasive free. The species listed on the NHIS within one mile of the Project are Prairie Bush-clover (Lespedeza leptostachya), and the Northern Long-eared bat (Myotis septentrionalis). These species have the potential of being present in the Project area. Prairie Bush-clover was not identified at the Facility or Project area as part of the botanical survey. Because there is limited tree removal proposed, the Project is not anticipated to impact the Northern long-eared bat. As noted, the Facility’s stormwater-only discharges include TSS and CBOD, which will have NPDES limits to help to protect downstream aquatic life from negative TSS and dissolved oxygen impacts. Al-Corn will minimize impacts of phosphorus on downstream aquatic life by the expansion of the existing southeast stormwater pond, installation and management of the new stormwater ponds, and utilization of other site-appropriate BMPs.

d. Identify measures that will be taken to avoid, minimize, or mitigate adverse effects to fish,

wildlife, plant communities, and sensitive ecological resources.

Prairie Bush-clover was not identified at the Facility or Project area as part of the botanical survey. Because there is limited tree removal proposed (i.e. proposed removal of trees does not significantly change the overall nature and function of the local forested habitat), the Project is not anticipated to impact the Northern long-eared bat. Existing forested portion of the Facility are not proposed for disturbance as part of the Project. As noted, the Facility’s stormwater-only discharges include TSS and CBOD, which will have NPDES limits to help to protect downstream aquatic life from negative TSS and dissolved oxygen impacts. Al-Corn will minimize impacts of phosphorus on downstream aquatic life by the expansion of the existing southeast stormwater pond, installation and management of the new stormwater ponds, and utilization of other site-appropriate BMPs.

14. Historic Properties:

Describe any historic structures, archeological sites, and/or traditional cultural properties on or in close proximity to the site. Include: 1) historic designations, 2) known artifact areas, and 3) architectural features. Attach letter received from the State Historic Preservation Office (SHPO). Discuss any anticipated effects to historic properties during project construction and operation. Identify measures that will be taken to avoid, minimize, or mitigate adverse effects to historic properties. SEH contacted the Minnesota Historical Society – State Historic Preservation (SHPO) office on August 17, 2015, to request a Section 106 Review of the Project. A letter from SHPO dated September 30, 2015, listed two historic properties in the immediate vicinity of the Project, the Winona & Saint Peter Railroad: Claremont Township Segment (DO-CLT-009) and the Lehmann Farmstead Barn (DO-CLT-031). Due to the nature and location of the Project, SHPO recommended


an archaeological survey. A Cultural Resource Assessment (CRA) was completed. The CRA concluded that one National Register of Historic Places eligible property was identified within the one mile visual Area of Potential Effect. The CRA concluded that the Project will be minimally visible from the eligible property. The CRA recommends a finding of No Adverse Effect to Historic Properties and that Project clearance be granted with no further investigation or evaluation of the Project area required. Al-Corn is awaiting SHPO’s response. See Attachment 6 for historic property documentation.

Describe any scenic views or vistas on or near the project site. Describe any project related visual effects such as vapor plumes or glare from intense lights. Discuss the potential visual effects from the project. Identify any measures to avoid, minimize, or mitigate visual effects.

There are no scenic views or vistas on or near the Facility or Project area. The Facility is located in a relatively flat topographic setting allowing it to be visible from surrounding properties, the adjacent roadways and the rail line. The Project involves the removal of certain existing stacks and structures as well as the installation of new, higher stacks. See Attachment 1 for information on the existing and proposed stacks. Outdoor lighting is utilized at the existing Facility. Al-Corn will add additional lighting as part of the Project and direct it as needed.

16. Air:

a. Stationary source emissions - Describe the type, sources, quantities and compositions of any emissions from stationary sources such as boilers or exhaust stacks. Include any hazardous air pollutants, criteria pollutants, and any greenhouse gases. Discuss effects to air quality including any sensitive receptors, human health or applicable regulatory criteria. Include a discussion of any methods used assess the project’s effect on air quality and the results of that assessment. Identify pollution control equipment and other measures that will be taken to avoid, minimize, or mitigate adverse effects from stationary source emissions.

The Project will include installing a new natural gas combustion turbine with a duct burner for combined heat and power and adding one additional natural gas fired boiler, DDGS dryer and RTO. A detailed list of existing and proposed equipment is provided in Attachment 1. The Facility’s potential to emit (PTE) for regulated pollutants, both now and after completion of the Project, is provided in Table 5 below. Pollutants generated by Facility operations include particulate matter (PM), PM less than 10 microns in diameter (PM10), PM less than 2.5 microns in diameter (PM2.5), sulfur dioxide (SO2), oxides of nitrogen (NOx), carbon monoxide (CO), and VOCs, greenhouse gases (GHG) in carbon dioxide equivalents (CO2e), and hazardous air pollutants (HAPs).

* The single HAP with the highest PTE is acetaldehyde. ** Potential to emit from the Facility, as presented in the current Total Facility Operating Permit. *** Includes the emissions from TK008 – new day tank (not yet added to the Total Facility Operation Permit).

Emission increases at the Facility resulting from the Project have been included in an air permit application to the MPCA and as part of an air dispersion modeling analysis for compliance with the National Ambient Air Quality Standards (NAAQS), the Minnesota Ambient Air Quality Standards (MAAQS) and the MPCA air emissions risk analysis (AERA) risk assessment screening spreadsheet (RASS) air emissions analysis. The predicted emission concentrations from the Facility are within the NAAQS and the MAAQS.

To assess whether the Project will cause or contribute to an air quality violation, Al-Corn completed a Significant Impact Level (SIL) analysis for the Project using the U.S. Environmental Protection Agency regulatory plume dispersion model AERMOD. Pollutants modeled in the SIL analysis were SO2, CO, PM10, PM2.5, and NO2. The modeled concentrations of each pollutant were compared to their respective SIL value using High First High (H1H) modeled impacts. Table 6 lists the SIL modeling analysis results for the various averaging periods.

AERMOD predicted exceedance of the SILs for NO2, PM10, and PM2.5. Al-Corn then used AERMOD to conduct a cumulative dispersion modeling analysis for all receptors greater than the SIL. The cumulative analysis included background concentrations of the four pollutants that exceeded the SIL. Al-Corn used the MPCA GIS Nearby Source tool to determine the nearby facilities to include in the cumulative analysis. Al-Corn compared the cumulative impacts from these sources and the background against the NAAQS and MAAQS. The Facility’s cumulative modeling results predicted a maximum impact that was below the NAAQS and MAAQS for all pollutants modeled for all averaging times as shown in Table 7.

The Project includes the permitting and installation of a new wet scrubber to control VOCs and hazardous air pollutants from fermentation equipment. Fabric filters and centrifugal collectors will also be installed to control PM, PM10, and PM2.5 emissions from grain handling equipment. Al-corn will install a new RTO to control VOCs, hazardous air pollutants, and CO emissions. Al-Corn will install a new flare to control VOC emissions from the ethanol loading rack. The MPCA requires an Air Emission Risk Analysis (AERA) for projects that trigger the preparation of an EAW under Minn. R. 4410.4300, subp. 15(B), which is for construction of a stationary source facility that generates a combined 100,000 tons per year or more of greenhouse gas emissions. The AERA includes both a quantitative analysis of potential impacts to human health using MPCA’s RASS, and a qualitative analysis using information from the Facility and the surrounding community. Al-Corn submitted an AERA on April 21, 2016. Al-Corn revised the AERA on April 29, 2016. The MPCA conditionally approved the revised AERA for inclusion in the EAW on May 10, 2016. Al-Corn submitted additional AERA information to MPCA on June 7, 2016. Al-Corn used the MPCA’s RASS to evaluate the acute toxicity, chronic toxicity, and cancer risks associated with emissions from the Project. The RASS conservatively considers the relative health risk for each pollutant emitted by the Project. The results of this assessment determine the need for additional evaluation. Al-Corn calculated the acute inhalation hazard index using high-end emission inputs and conservative exposure parameters and resulted in a value of less than one. Therefore, the MPCA does not expect acute emissions to adversely affect human health. The basis for the chronic hazard and lifetime excess cancer risk estimates were on the


limited annual emissions to reflect more accurate proposed plant operations. The chronic multi-pathway hazard analysis yielded results less than one. The chronic lifetime excess cancer risk estimate was less than the threshold of 1E-5, or one in 100,000. Both the acute and the chronic risk values are acceptable because they are at or less than the risk thresholds. The qualitative risk analysis describes the area surrounding the Facility. The Project should not affect any sensitive receptors (i.e., residences, parks, day cares, and schools) located beyond the Facility fence lines. The results of the RASS show that the Project does not need further evaluation for toxicity and cancer risks. Al-Corn and MPCA do not expect the Project to adversely affect human health and the environment. The AERA Report is provided in Attachment 7.

b. Vehicle emissions - Describe the effect of the project’s traffic generation on air emissions. Discuss the project’s vehicle-related emissions effect on air quality. Identify measures (e.g. traffic operational improvements, diesel idling minimization plan) that will be taken to minimize or mitigate vehicle-related emissions. Al-Corn conducted air dispersion modeling to determine the Project’s impact on air quality. The results of the modeling indicate that the Project will meet all NAAQS and MAAQS. Vehicle combustion emissions (i.e., tailpipe exhaust emissions) are not directly regulated for stationary facilities and were not modeled directly, but were accounted for in the air dispersion modeling via assumed background pollutant concentrations.

The Project will increase the amount of corn and denaturant received as well as the amount of corn oil, DDGS, and ethanol loaded out, as shown in Tables 9 and 10 under Item 18 below. Al-Corn will manage the increases in commodity shipping using both rail and truck. While the volume of truck traffic will increase, Al-Corn expects that the proposed rail loop will be able to handle all of the increased shipping needs for grain, DDGS, and ethanol. Al-Corn will conduct truck loading and unloading in a manner to reduce onsite idling, thus minimizing emissions from the truck engines. All existing haul roads at the Facility are currently paved and Al-Corn will pave all new haul roads constructed at the Facility and Project area as part of the Project. In accordance with the Facility’s air permit, Al-Corn will maintain a Fugitive Dust Emission Control Plan to minimize fugitive dust emissions from Facility operations, including haul roads. The number of employee vehicles accessing the Facility on a daily basis will not significantly increase.

c. Dust and odors - Describe sources, characteristics, duration, quantities, and intensity of dust and odors generated during project construction and operation. (Fugitive dust may be discussed under item 16a). Discuss the effect of dust and odors in the vicinity of the project including nearby sensitive receptors and quality of life. Identify measures that will be taken to minimize or mitigate the effects of dust and odors. No significant change in type or quantity of odors from the Facility is expected as a result of the Project. All distillers’ grains are dried; wet distillers’ grains can be a source of odor, but Al-Corn does not and will not store wet distiller’s grains outdoors. Exhaust from the new dryer, existing


biogas from methanators, and dryer exhaust are routed to the existing dryers or RTO. All DDGS is stored in bins indoors or outdoors. The nearest sensitive air receptor is a residence located southwest approximately 2,200 feet from the thermal oxidizer.

17. Noise:

Describe sources, characteristics, duration, quantities, and intensity of noise generated during project construction and operation. Discuss the effect of noise in the vicinity of the project including 1) existing noise levels/sources in the area, 2) nearby sensitive receptors, 3) conformance to state noise standards, and 4) quality of life. Identify measures that will be taken to minimize or mitigate the effects of noise.

The Facility currently operates, and will continue to operate, 24 hours per day, 7 days per week. No significant additional noise impacts from the Facility are expected as a result of the Project. Al-Corn will install most of the new equipment indoors, including hammermills. The new natural gas powered turbine will be in a building located in the south central part of the Facility. Existing equipment that is located outdoors includes the following: Grain and DDGS bins and conveyors, DDGS cooler, distillation and dehydration towers, fermenters, cooling towers, CO2 scrubbers, generators, and RTO. The new dryer installed as part of the Project will also be located outdoors. Some noise generating equipment will be constructed outside. This includes the addition of a second cooling tower and ethanol dehydration system. While this is a doubling of the size of those systems, they will operate at the same or lower noise levels. According to the MPCA guidance “A Guide to Noise Control in Minnesota” dated November 2015, (Noise Guidance), doubling sources of the same or lower noise levels will result in minimal noise increases; thus the MPCA expects a minimal change from existing noise conditions. Construction activities will generate noise primarily during daylight hours for a period of 18-22 months. Al-Corn will require construction contractors to use equipment with sound abatement consistent with industry standards The nearest sensitive receptor to the Facility is a residence, located approximately 0.4 miles to the northwest across US Highway 14. There is minimal change in the distance to the nearest sensitive receptor as a result of the Project. According to the Noise Guidance, this residential property is a Noise Classification Area (NAC) 1. The Minnesota noise standard requires that the noise reaching a NAC 1 property must conform to the most stringent standards. The Facility and the Project cannot exceed the state noise standards under Minn. R. ch. 7030 at the nearest residential property. The noise standards are shown in Table 8 below.

18. Transportation: a. Describe traffic-related aspects of project construction and operation. Include: 1) existing and

proposed additional parking spaces, 2) estimated total average daily traffic generated, 3) estimated maximum peak hour traffic generated and time of occurrence, 4) indicate source of trip generation rates used in the estimates, and 5) availability of transit and/or other alternative transportation modes.

There are 100 existing paved pull-in spaces available for vehicle parking and 150 parallel parking spaces available for vehicle parking and truck staging at the Facility. As part of the Project, Al-corn will construct an additional 140 parallel parking spaces for truck staging along proposed interior Facility roadways. During high construction activity and plant maintenance during shutdowns, there will be approximately 200 contractor vehicles in addition to the current number of vehicles at the Facility. No additional parking spaces are proposed, as the number of available spaces will adequately handle the number of additional staff and peak construction contractor vehicles. Following completion of the Project, Al-Corn projects an additional 146 trucks per day will be entering/exiting the Facility, assuming that no rail transportation occurs. However, it is expected that rail transportation will replace truck transportation as the preferred method of transit for the ethanol and DDGS products. If Al-Corn ships ethanol and DDGS products by rail, truck traffic will be approximately 80 additional trucks per day for local corn delivery. Corn and DDGS truck traffic will generally occur Monday through Friday, 6 a.m. to 6 p.m., as these are the hours of the Facility scale operation. Ethanol and corn oil truck loading can occur 24 hours per day 7 days a week. The approach to truck unloading provides for up to four lanes of parking within the Project area. Currently, trains utilize the Facility 10 times per year for DDGS shipping with trains approximately 10 cars in length. Al-Corn expects the Project to result in an increase in train traffic to 2 times per week for DDGS and ethanol shipping with trains approximately 100 cars in length. The rail loop will accommodate up to two trains, with 100 rail cars each. Train operation will occur 24 hours per day when loading or unloading. There is no set schedule for the operation of trains. Loading of denatured ethanol onto a train will take approximately 48-60 hours. Loading of DDGS onto rail cars will take approximately one hour per car. See Table 9 and Table 10 below for the projected number of trucks and trains for all incoming and outgoing materials.

Facility Totals 10 104 **Does not take into account portion of denatured ethanol and DDGS shipped out via truck or grain received via truck. b. Discuss the effect on traffic congestion on affected roads and describe any traffic

improvements necessary. The analysis must discuss the project’s impact on the regional transportation system. If the peak hour traffic generated exceeds 250 vehicles or the total daily trips exceeds 2,500, a traffic impact study must be prepared as part of the EAW. Use the format and procedures described in the Minnesota Department of Transportation’s Access Management Manual, Chapter 5 (available at: http://www.dot.state.mn.us/accessmanagement/resources.html) or a similar local guidance. The Facility will have an increase in truck traffic after completion of the Project due to the increase in grain receiving and product loadout. The Project will create an approximate maximum 2% increase in traffic on US Highway 14, with a maximum of 146 vehicles added to the existing 7,800 annual average daily traffic (AADT) count collected by the Minnesota Department of Transportation (MnDOT). The Project will create an approximate maximum 9% increase in traffic on 120th Avenue with a maximum of 146 vehicles added to the existing 1,650 AADT MnDOT count. The 2013 AADT traffic counts include existing vehicle traffic to the Facility. Traffic congestion is not anticipated. The MPCA does not anticipate that the Project will cause an increase in traffic congestion. The anticipated increase in traffic volume levels is below the requirements for a traffic impact study. As a result, no traffic improvements are planned at this time. MnDOT has future plans to upgrade and re-route the portion of US Highway 14 that borders the Facility on the north. MnDOT plans to re-route US Highway 14 to the south of the Facility and expand it from a two-lane roadway to a four-lane roadway with the addition of turning lanes (Highway Project). The timing of the Highway Project is unknown as it does not yet have funding; however, it is expected that when completed, the Highway Project will reduce Al-Corn’s traffic impact. The existing two-lane road with turning lanes (old Highway 14) will remain in service north of the Facility after the Highway Project is complete. The proposed location of the Highway Project is shown on Figure 12.


c. Identify measures that will be taken to minimize or mitigate project related transportation effects. The MPCA does not anticipate that the Project will result in an increase in traffic congestion and no traffic improvements are required or planned at this time for the Project. Future traffic flow is expected to lessen near the Facility when the planned re-location of US Highway 14 is completed to the south of the Facility. The designed rail loop is able to accept full length trains without delaying trains traveling on or off the main line and through roadway crossings.

19. Cumulative Potential Effects: (Preparers can leave this item blank if cumulative potential effects

are addressed under the applicable EAW Items) a. Describe the geographic scales and timeframes of the project related environmental effects

that could combine with other environmental effects resulting in cumulative potential effects.

Under Minn. R. 4410.0200 and 4410.1700, the MPCA must consider the cumulative effects of anticipated future projects when determining the need for an Environmental Impact Statement on a project. The analysis considers the added environmental effects when combined with all the incremental environmental effects associated with the Project. The primary environmental effect from the Project is the increase in air emissions from the Facility. This will be an on-going long-term effect for as long as the Facility is in operation. As shown previously in the modeling analyses and the AERA Report, the impact of the Project will not cause or contribute significantly to possible air quality exceedances or to adverse human health effects under normal operations. The AERA Report is a cumulative evaluation of potential risk and hazard to human health from the Project. It details the qualitative environment near the Facility and the quantitative potential lifetime excess cancer risk and hazard from the cumulative effects of potentially emitted chemicals. The quantitative analysis resulted in potential risks and hazard less than the MDH threshold levels. Al-Corn will manage the environmental effects of the Facility by compliance with proposed limits and conditions within the air permit.

b. Describe any reasonably foreseeable future projects (for which a basis of expectation has been laid) that may interact with environmental effects of the proposed project within the geographic scales and timeframes identified above.

Al-Corn contacted the City regarding any future projects to be constructed in close proximity to the Facility. The City identified one project with known construction plans within the next 18 to 22 months that will be located approximately 3,700 feet east of the Facility as shown on Figure 13. The proposed project is a dry fertilizer plant (Plant) planned by CHS that will be a 2.73 acre parcel (Dodge County Parcel No. 210284300) adjacent to the main rail line. The Plant will be housed in a 30,000 ft2 building and will store 12,000 tons of blended product. The projected throughput of the Plant is 12,000 tons of fertilizer per year. The product is a blend of urea, potash and phosphorus; all truck unloading, mixing and loading for that Plant will occur inside the building. There are no air emissions projected, as unloading and loading occur indoors.

The Plant will ship less than 12,000 tons/year of product, which accounting for incoming and outgoing material is less than 16 trucks per day during peak season. The effects of this additional amount of additional truck traffic will be minor.


c. Discuss the nature of the cumulative potential effects and summarize any other available information relevant to determining whether there is potential for significant environmental effects due to these cumulative effects.

Groundwater The MPCA does not expect the Project to result in significant impacts to groundwater. The Project will result in an increased need for water. Al-Corn intends to use an existing well at the Facility (Map ID 8) is currently not used for production and screened within the deeper aquifer (Prairie du Chien-Jordan) to support the Facility’s increase in ethanol production as well as provide a back-up to existing water supply wells screened in the shallower Dubuque-Galena Group. Based on the aquifer test data and the analysis results, Well Map ID 8 is capable of sustaining a yield in excess of 700 gpm without long-term depletion of the ground-water resource. The Facility does and will continue to store hazardous materials and substances at the Facility after completion of the Project. All tanks will include the appropriate required measures for spill response and secondary containment to minimize the potential risks to groundwater contamination. MDH well log information indicates shallow groundwater is approximately 30-40 feet below ground surface. Based on the aquifer test data and the low risk for contamination due the secondary containment systems and depth to groundwater, the MPCA does not expect the Project to contribute to cumulative impacts to groundwater. Surface Water Al-Corn anticipates approximately 0.30 acres of wetland impacts as a result of the Project. Al-Corn will mitigate any approved impacts through the purchase of wetland credits from an USACE or BWSR approved wetland bank in the same major watershed as the Project. The Facility straddles the boundary between the upper South Branch Middle Fork Zumbro River and Judicial Ditch No. 7 (Havana Ditch) to Dodge Center Creek. As noted, the Facility’s stormwater-only discharges include TSS and CBOD, which will have NPDES limits to help to protect downstream aquatic life from negative TSS and dissolved oxygen impacts. Al-Corn will minimize impacts of phosphorus on downstream aquatic life by the expansion of the existing southeast stormwater pond, installation and management of the new stormwater ponds, and utilization of other site-appropriate BMPs. Through the proper use of temporary construction BMPs and permanent stormwater control measures on the Facility and Project area, the MPCA does not expect the Project to contribute to cumulative turbidity issues in the Zumbro River watershed.

Land use Rural agricultural land, rural residences, and farmsteads surround the Facility. The Facility and Project area are currently zoned as agricultural and industrial. Al-Corn’s planned land use includes utilizing some of the existing agricultural farmland area for a railroad loop, spur, and stormwater ponds. The Project is compatible with existing land use plans. There are no known identified fish communities or rare features and ecosystems identified within the Project area. Wetlands 5 and 6 are wooded basins surrounded by agricultural land and will be impacted by the proposed rail loop. The wildlife species observed and/or expected to use the agricultural fields or wooded wetlands are mobile and will ultimately move to other

Thank you for submitted the attached survey results for the Al-Corn Ethanol Facility Expansion. The edible valerian (Valeriana edulis var. ciliata) identification has been verified and, as stated in the report, this state-listed threatened plant has been documented within the project footprint.

Minnesota’s endangered species law (Minnesota Statutes, section 84.0895) and associated rules (Minnesota Rules, part 6212.1800 to 6212.2300 and 6134) prohibit the taking of threatened or endangered species without a permit. As avoidance is not proposed, please contact Richard Baker ([email protected]) to discuss the takings permit application process.

Thank you,

Lisa Joyal

Lisa,

Please find the attached report for the botanical survey completed for Al Corn, in Claremont Minnesota. We did confirm the presence of generally low quality native prairie, but did find three target species. Edible valerian is the primary find, as it is listed as threatened.

The report is attached, as are the reporting spreadsheets and shapefile.

We do anticipate a takings, as the proposed rail loop coincides with the occurrences. These are unavoidable, given the need for the project to connect to the existing rail. We'll coordinate with Rich Baker, but want to allow you the opportunity to review and concur with the findings first.

Thanks.

MEMORANDUM – BOTANICAL SURVEY

TO: Lisa Joyal, Minnesota Dept. of Natural Resources FROM: Natalie White, SEH Biologist DATE: July 6, 2016 RE: Al-Corn Rare Plant Survey SEH No. ALCCF 133307 14.00 Introduction This Technical Memorandum describes the results of a plant survey conducted on June 27, 2016 near the City of Claremont in Dodge County, Minnesota for Al-Corn Clean Fuel (Figure 1). Al-Corn is an ethanol producer, and is proposing to expand their operations by adding a rail loop and access to the railroad located south of their facility. The majority of the project area is currently in agricultural production, however there are small portions along the railroad and a township road, in which native plant communities may be present. Field survey was completed by Deric Deuschle, Sr. Biologist and Natalie White, Botanist, with assistance by Rebecca Beduhn, Soil Scientist. This memo describes the survey protocol and findings for state-listed flora in the survey area. The survey was targeted to roughly 1.9 acres of priority areas identified as having higher probability of containing the target species. This area was identified using data gathered from the Natural Heritage database, previous site visits that confirmed that native prairie species were present, and general understanding that railroad corridors are known to harbor remnant prairie habitats. Project Area Description The survey area consists of a strip of vegetation and prairie located between the DM&E railroad tracks and cultivated fields, north of the railroad tracks, and stretching both east and west from 110th Avenue (Figure 2). The western reach extended approximately 1,400 feet from 110th Avenue, while the eastern segment extended a shorter 1,000 feet from 110th Avenue. The limits were generally determined by the anticipated construction limits. The width of vegetation between the toe of the railroad ballast and cultivated field is approximately 35 feet on the western reach, and 30 feet on the eastern reach. Outside of the narrow corridors, one wider pocket at the northeast quadrant of the intersection of 110th Avenue and the railroad tracks was also surveyed (Figure 3). Methodology Methodology for this survey was developed through coordination with the Minnesota Department of Natural Resources (MNDNR). Three species were listed in the Natural Heritage Information System (NHIS) as present in the project area: rattlesnake master (Eryngium yuccifolium – state special concern), cowbane (Oxypolis rigidior – rare, but not state listed), and edible valerian (Valeriana edulis var. ciliata – state threatened). Given the small size and the accessibility of the site, a comprehensive survey of site flora was conducted. Surveyors meandered through the site and recorded all species observed. Locations of rare plant occurrences were collected with a GPS unit capable of sub-meter accuracy. Due to the small size and accessibility of the site, occurrences were not flagged in the field so as not to draw attention to individual species occurrences. Because the target species are distinctive, and the populations in question are not large, specimens were not collected. Photographic evidence and the qualifications of the observers were presumed to be adequate to document species occurrences.

Al-Corn Rare Plant Survey July 6, 2016 Page 2 For the prairie areas, surveyors recorded condition/quality of the plant communities. The prairie was classified in units, according to the quality and closest Native Plant Community classification. This may assist with project planning, as avoidance of the highest quality areas would be the goal. Results Timing of the survey was ideal for identification of the three target species, with all being visible/identifiable in late June. Surveyors observed that an approximately 5-10 foot wide strip west of 110th Avenue along the railroad tracks had been sprayed with herbicide in the recent past, presumably overspray from treatment of the railroad ballast, and most species in this area were yellowed or dead (see Photo 1 in attached photo pages). One occurrence of edible valerian had been noted in this area during an earlier visit (May 27th, 2016) for wetland delineation, and could not be relocated at the time of the June 27th survey. This individual edible valerian was likely killed by the herbicide overspray. Presumably, this herbicide application is a regular occurrence, as the vegetation immediately adjacent to the railroad tended to be less diverse, and more grass-dominated. Herbicide had also been applied to the south side of the tracks, but with a much more limited area of effect. Similar fringe herbicide effects were noted along the corn fields, but did not occur within areas of native prairie, and were more limited in lateral effects. All three target species were located during the field survey. Table 1 below summarizes the findings. Photo documentation of a number of the occurrences is included in the attached photo pages; all other photographs have been retained on file at SEH.

The survey encountered no occurrences of other listed species. A comprehensive species list is attached, with separate lists for the strip along the railroad west of 110th Avenue, the strip along the railroad east of 110th Avenue, and the pocket of prairie in the northeast quadrant of the 110th Avenue and railroad intersection. Plant Community Ranking The plant community along the railroad west of 110th Avenue is best described as a D rank occurrence of upland prairie. The closest Native Plant Community classification (NPC) is Southern Mesic Prairie (UPs23); but the area is not likely high enough quality to classify as an NPC. There is a poor diversity of native grasses, and the graminoid community was dominated by smooth brome (Bromus inermis) and Kentucky bluegrass (Poa pratensis). Although Canada goldenrod (Solidago canadensis) is common and the site has been invaded by wild parsnip (Pastinaca sativa), the forb community is generally more typical of UPs23. Golden alexander (Zizia aurea), Stiff goldenrod (Solidago rigida), stiff sunflower (Helianthus pauciflorus), white sagebrush (Artemisia ludoviciana), northern bedstraw (Galium boreale), Maximilian’s sunflower (Helianthus maximiliani), and tall meadow rue (Thalictrum dasycarpum) were frequently encountered. The narrow strip of prairie is under pressure from invasive species encroachment from the fields to the north, and herbicide overspray from the adjacent trailroad; grazing is not an issue in this area. The plant community along the railroad east of 110th Avenue is best described as disturbed, non-native grassland. Dominant species in this area are reed canary grass (Phalaris arundinacea), wild parsnip, and giant ragweed (Ambrosia trifida). Quality of the prairie improves to the east, but outside the project area. A single rattlesnake

Al-Corn Rare Plant Survey July 6, 2016 Page 4 master was observed on the eastern fringe of the project area, but otherwise, the diversity and quality is less than other areas observed. A portion of the corridor is cropped very close to the railroad, and serves to provide a barrier to the continuous strip of prairie and non-native species present along the corridor. The plant community at the northeast quadrant of the intersection of the railroad and 110th Avenue consists of a very small pocket of C-D rank mesic prairie. The area dominated by native species is less than 2,000 square feet, with occurances occurring within less than 1,000 square feet. The closest Native Plant Community classification (NPC) is Southern Mesic Prairie (UPs23), grading to Southern Wet Prairie (WPs54). There is a poor diversity of native grasses, but there is prairie cordgrass (Spartina pectinata) as well as a number of native sedges (Carex sp.) present in wetter areas. Disturbance increaser species such as giant goldenrod, sawtooth sunflower, and field horsetail (Equisetum arvense) are common. Other typical species in the forb community include prairie coreopsis (Coreopsis palmata), grass-leaved goldenrod (Euthamia graminifolia), prairie blazing star (Liatris pycnostachya), northern bedstraw, and tall meadow rue. The small pocket of prairie is under pressure from invasive species, herbicide overspray, roadside mowing, and encroachment of adjacent trees and shrubs; grazing is not an issue in this area. Regulatory Considerations Rare species are regulated by the MNDNR, and removal or disturbance requires coordination and issuance of a takings permit. Of the species observed, only Edible valerian has legal protection, as the other two are special concern, or have no official status. It is anticipated that the proposed project will impact the Edible valerian plants that have been observed. It is recommended that early coordination be initiated to allow sufficient time to review and process the request. Mitigation for taking listed species may be required, and is expected to be discussed as part of the takings process. Mitigation may take the form of relocation, habitat restoration, preservation, support of research, or other financial considerations. Mitigation is typically negotiated, and is dependent on the extent of the taking, and the effects on the rare plant population. Means of completing the project that would avoid or minimize impacts must also be considered, and will be required to be demonstrated prior to approval of a mitigation plan and issuance of a takings permit. No federally listed species were observed, therefore coordination is required at the state level only. nw Attachment: Figure 1. Site Location Map Figure 2. Aerial Photograph Figure 3.

Sarah BeimersManager of Government Programs and ComplianceMinnesota Historical Society345 W Kellogg BlvdSt. Paul, MN 55102-1906

Dear Ms. Beimers:

The purpose of this letter is to request Section 106 Review on the Al-Corn Clean Fuel facility upgrade. Al-Corn Clean Fuel in Claremont, MN, is proposing a facility upgrade, expansion and consolidation project (the Project) that would include installation of a natural gas combustion turbine to produce on-site heat and power, relocation and expansion of grain receiving and DDGS handling operations, replacement and addition of a boiler and regenerative thermal oxidizer (RTO), new Distiller's Dry Grains and Soluble (DDGS) truck loadout, addition of a rail loop for ethanol and DDGS shipment and the expansion of ethanol fermentation, distillation and dehydration capacity.

One of the requirements of the grant is the completion of an Environmental Assessment (EA). As part of this, it is requested that the Minnesota Historical Society please review the proposed project and comment on any properties listed on the National or State Registers of Historic Places. It is also requested that comments be made on any known or suspected archaeological properties in the area.

The project is located in the township of Claremont, Dodge County, Minnesota. The project address is: 797 5th St, Claremont, MN 55924

Please send the SHPO comment letter to:Rebecca BeduhnSEH Scientist3535 Vadnais Center DriveSt. Paul, MN 55110

MEMORANDUM

TO: Monika Vadali, MPCA

FROM: Katie Hill Brandt, SEH

DATE: June 6, 2016

RE: Additional Information for RASS SEH No. ALCCF 133307 32.00

The following information is provided as a supplement to the Risk Assessment Screening Spreadsheet (RASS) for Al-Corn Clean Fuel dated April 29, 2016, in response to the RASS Review Notification received on May 10, 2016.

FACILITY DESCRIPTION Al-Corn is an existing facility located south of State Highway 14, approximately one mile west of Claremont in Dodge County. The plant’s current capacity is 50 million gallons per year (MMgal/year) of 200-proof ethanol with a corn throughput of approximately 18 million bushels per year (MMBu/year). Al-Corn proposes to construct an expansion that would increase their corn processing capacity by 29 MMBu/year, to approximately 47 MMBu/year. This would provide the capacity to produce 130 MMgal/year of undenatured ethanol, 350,000 tons/year of distiller’s grains and nearly 4 MMgal/year of corn oil. The construction project will occur within the current facility’s footprint and three undeveloped parcels of agricultural land adjacent to the existing plant site owned by Al-Corn to the west. In 2012 to 2015, the facility proposed a 10 MMgal/year production increase related primarily to process efficiency. This proposed project includes this past production increase request. Al-Corn submitted a Draft EAW for review by the MPCA on April 4, 2016.

STACK INFORMATION AND SUMMARY OF INPUTS Sources of air toxics at proposed facility were included in the RASS. Each source was modeled with a unit emission rate (1 gram/second) in AERMOD with receptors along the proposed facility fenceline. Model set-up otherwise follows the project dispersion modeling protocol which was approved by MPCA on April 14, 2016. Results for each source were input in the RASS as dispersion factors for the 1-hour, 3-hour, 8-hour, 24-hour, monthly, and annual time periods. The attached table shows stack information as modeled for the RASS.

Emergency Engine The proposed project includes the installation of a new emergency fire pump engine. This engine was not included in the dispersion modeling or RASS. The engine will only be operated for emergencies and routine testing and maintenance, and the air permit will incorporate Best Management Practices (BMPs) for this engine.

Non-Emergency Engines Al-Corn operates six existing non-emergency engines at the facility. The engines participate in an Emergency Demand Response Program by way of peak shaving. Thus, these engines were modeled using monthly and hourly emission scalars based on meteorological analysis of Temperature-Humidity Index (THI) data for Owatonna, MN. This modeling approach follows the approved project dispersion modeling protocol.

Attachment 7

Additional Information for RASS June 6, 2016 Page 2 SENSITIVE RECEPTORS A number of sensitive receptors exist within three kilometers of the facility, including public recreations areas, nearby residents, and churches. See attached Figure 1 – Project Location and Buffer Area for sensitive receptors within a three kilometer buffer. The RASS indicated that no air toxics endpoint refinement outside the facility fence line is required for the proposed Al-Corn facility. Thus, sensitive receptors were excluded from the analysis. FARMLAND PROXIMITY Al-Corn is virtually surrounded by farmland, with the exception of State Highway 14 to the north and a railroad to the south. Refer to attached Figure 5 – Land Cover and Figure 6 – Agriculture Cropland Types which show neighboring farmland within 10 kilometers of the facility. RESIDENTIAL PROXIMITY A number of nearby residences exist within three kilometers of the facility. As show in Figure 1, there are residences located north and south of the facility. RESULTS The RASS results for the proposed facility indicate that a refined air toxics analysis is not required. The total multi-pathway screening hazard indices and cancer risks are presented in the table below.
