1.2 Facility description

Tiller owns and operates the pits and hot mix asphalt plant at the Tiller Maple Grove Facility, a mining and construction sand and gravel processing facility. The facility will have the potential to consist of five primary spreads: sand and gravel spread, recycled concrete and asphalt spread, screening spread, bituminous aggregate spread, and a hot mix asphalt plant. Tiller originally had pits #702, 703, 709, and 724 under a Nonmetallic Mineral General Permit (Permit No. 05301018-002) and a hot mix asphalt plant (Plant #904) under a Registration Option D Permit (Permit No. 99000285-001). Tiller submitted an Individual State Operating Permit to combine these pits under a single permit to allow flexibility on production and/or number of equipment beyond what is allowed in the NMGP. Tiller is also going to have an aggregate heater onsite, which the NMGP would not allow a sand heater exceeding a facility total of 10 MMBtu/hr. The NMGP will remain in effect for said pits until issuance. Upon issuance of the Individual State Permit, the NMGP will remain in effect for other existing Barton Sand & Gravel Co., operating division of Tiller, sources in Minnesota not including pits #702, 703, 709, and 724. The Registration Option D Permit will remain in effect until issuance of the Individual State Operating Permit.

1.3 Description of the activities allowed by this permit action

This permit action is State Permit. The Minnesota Pollution Control Agency (MPCA) has a combined operating and construction permitting program under Minnesota Rules Chapter 7007, and under Minn. R. 7007.0800. Under that authority, this permit action authorizes construction.

2. Regulatory and/or statutory basis

2.1 New source review (NSR) The permit carries forward limits on the facility such that it is a synthetic minor source under New Source Review regulations. No changes are authorized by this permit.

2.2 Part 70 permit program

The permit carries forward limits on the facility such that it is a nonmajor source under the Part 70 permit program.

2.3 New source performance standards (NSPS) The Permittee has stated that New Source Performance Standards apply to the operations at this facility. 40 CFR Part 60, subp. Dc (Standards of Performance for Small Industrial-Commercial-Institutional Steam Generating Units) establishes standards of performance for steam generating units for which construction, modification, or reconstruction commenced after June 9, 1989 and that has a maximum design heat input of 10-100 MMBtu/hr. By the definition of a steam generating unit in this subpart, the aggregate heater and asphalt cement tank heater are not considered to be a steam generating unit, therefore NSPS Subpart Dc are not applicable. 40 CFR Part 60, Subp. Kb (Standards of Performance for Volatile Organic Liquid Storage Vessels) establishes standards for volatile organic liquid storage vessels for which construction, reconstruction, or modification commenced after July 23, 1984. However, NSPS Subpart Kb does not apply to storage vessels with a capacity less than 75 cubic meters (approx. 19,800 gallons). The asphalt cement tank at the facility is not considered a volatile organic liquid and is not subject to NSPS Subpart Kb. The facility has used/waste oil storage tank with a capacity of 20,000 gallons however, the vapor pressure of the used/waste oil will be below 15.0 kPa, therefore the tank will not be subject to NSPS Subpart Kb due to 40 CFR 60.110b(b). 40 CFR Part 60, Subp. I (Standards of Performance for Hot Mix Asphalt Facilities) provides standards for hot mix asphalt facilities including dryers; systems for screening, handling, storing, and weighing hot aggregate; systems for loading, transferring, and storing mineral filler; systems for mixing hot mix asphalt; and the loading, transfer, and storage systems associated with emission control systems. Tiller has a hot mix asphalt plant at the facility and will be subject to NSPS Subpart I.


40 CFR Part 60, Subp. OOO (Standards of Performance for Nonmetallic Mineral Processing Plants) provides standards for nonmetallic mineral processing plants. Tiller facility will have nonmetallic mineral processing plants and will therefore be subject to NSPS Subpart OOO. Tiller will have some equipment from the process that will not be subject to NSPS Subpart OOO due to the construction, modification, or reconstruction date. 40 CFR Part 60, Subpart UUU (Standards of Performance for Calciners and Dryers) provides standards for calciners and dryers at mineral processing plants. By the definition of mineral processing plants in 40 CFR 60.731, Tiller is not considered a mineral processing plant because construction sand and gravel and hot mix asphalt is not considered lightweight aggregate. Therefore, NSPS Subpart UUU is not applicable. 40 CFR Part 60, Subpart IIII (Standards of Performance for Stationary Compression Ignition Internal Combustion Engines) provides standards for compression ignition (CI) internal combustion engines. 40 CFR 60.4219 defines stationary internal combustion engine as: “any internal engine, except combustion turbines, that converts heat energy into mechanical work and is not mobile. Stationary internal combustion engines (ICE) differ from mobile ICE in that a stationary ICE is not a nonroad engine as defined at 40 CFR 1068.30 (excluding paragraph (2)(ii) of that definition).” The engines at Tiller are portable and are moved around among Tiller sites such that they are not located at any location longer than 12 months. Therefore, they are not subject to NSPS Subpart IIII.

The diesel engine (EQUI 004) meets the definition of a stationary internal combustion engine; however, the engine was manufactured and installed prior to July 11, 2005 (applicable date from NSPS Subpart IIII) and is therefore not subject to NSPS Subpart IIII.

2.4 National emission standards for hazardous air pollutants (NESHAP) Tiller Facility is an area source of HAPs. There are two potential area source NESHAPs applicable to the Tiller Facility: 40 CFR Part 63, subp. ZZZZ and 40 CFR Part 63, subp. AAAAAAA. NESHAP ZZZZ (National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines) Tiller has a diesel stationary engine (EQUI 004) that was constructed before June 12, 2006 and is therefore considered an existing stationary reciprocating internal combustion engine (RICE) under 40 CFR Part 63, subp. ZZZZ. NESHAP AAAAAAA (National Emission Standards for Hazardous Air Pollutants for Area Sources: Asphalt Processing and Asphalt Roofing Manufacturing) 40 CFR Part 63, subp. AAAAAAA applies to owners or operators of asphalt processing operations and/or asphalt roofing manufacturing operations at area sources of HAP emissions. Under 40 CFR 63.11566 it defines asphalt processing operation as: “…any operation engaged in the preparation of asphalt flux at stand-alone asphalt processing facilities, petroleum refineries, and asphalt roofing facilities. Asphalt preparation, called “blowing,” is the oxidation of asphalt flux, achieved by bubbling air through the heated asphalt, to raise the softening point and to reduce penetration of the oxidized asphalt. An Asphalt processing facility includes one or more asphalt flux blowing stills.” The hot mix asphalt plant at Tiller does not meet this definition and is therefore not subject to NESHAP AAAAAAA.


2.5 Compliance assurance monitoring (CAM) Tiller is not a major source required to have a Part 70 Permit. Therefore, CAM does not apply.

2.6 Minnesota State Rules

3. Technical information

Pre-CAP Permit Language The permit makes use of pre-cap limits for various pits in order to allow the Permittee to make changes if certain emission unit requirements are met. MPCA uses Pre-cap language in situations where emissions from the existing facility are low, the potential emissions from new units are high, but the actual emissions from the units are low, and changes to the facility are not expected to cause the facility to exceed NSR and/or Part 70 thresholds. Tiller Corporation utilizes portable equipment. The processing units go to various sites depending on the market demand. The permit therefore contains language to allow for flexibility in adding, removing, or replacing units. There are four different production lines in the permit (COMG 1, 2, 3, and COMG 4), each has a requirement for different amounts of crushers, conveyors, and screens allowed. The permit lays out the maximum number and capacity of each type of equipment allowed. The emission unit list provided in the emission calculations represents the maximum amount of equipment that could be active at the site at any given time. As such, this was implemented as a permit requirement in COMG 1, 2, 3, and COMG 4. The site’s PTE is limited by the process throughput limits so this requirement is


not required to limit emissions to below Part 70 and NSR thresholds. This requirement adds clarity to the other flexibility requirements and also limits the hourly emissions. To demonstrate compliance with replacement procedures, the site will maintain an inventory of the capacity and number of each equipment type onsite at all times. The Permittee is also required to keep an updated list of the manufacture/construction dates of each equipment on site for the purposes of NSPS. OOO applicability. The list will be updated as equipment is added, removed, or replaced from the site. Despite having the Pre-Cap language in the permit, the Permittee still must determine if some type of amendment is required. For example, the Permittee would still need a major amendment for Title I modifications, if the unit is subject to an applicable requirement that is not it the permit, or if recordkeeping/monitoring requirements need to be changed or added. Throughput Limits for COMG 1 and COMG 4 Instead of separate limits for the primary crusher and cone crusher, a total 12-month rolling sum limit was established using the combined throughputs of the primary and cone crusher at each spread. This was done to help simplify the recordkeeping and made it easier on the Permittee to obtain records, while maintaining their PTE assumptions. There was an issue with direct placement of belt scales after the cone crusher and crushed material bypassing the cone crusher at the two spreads and by combining the throughputs into one this will help account for all the material being processed at the spread. Within the permit itself the text on number of equipment and hourly capacities will remain in place.

3.1 Calculations of potential to emit (PTE) Attachment 1 to this TSD contains a summary of the PTE of the Facility, detailed spreadsheets, and supporting information prepared by the MPCA and the Permittee. The emission factors for conveyor sets, screens, primary crushing, secondary crushing, and tertiary crushing are from AP-42 factors Chapter 11 Mineral Products Industry. The Permittee took annual and hourly throughput limits to limit PTE below Part 70 and major PSD thresholds for Sand & Gravel Spread, Recycle Concrete & Asphalt Spread, Screening Spread, and Bituminous Spread. EQUI 1 combusts natural gas and uses AP-42 Section 1.4 emission factors. EQUI 2 has emission factors from AP-42 Section 11.1 based on natural gas and waste oil. The calculations also use an annual and hourly throughput limit on the HMA drum dryer. EQUI 3 uses emission factors from AP-42 and 40 CFR Part 98 (for greenhouse gas emissions). EQUI 4 PTE uses emission factors from AP-42 Section 3.4 and hourly emission rate from performance test for maximum generator load. EQUI 4 has a limit of 800 operating hours/year. PM emissions from paved roads were calculated using AP-42, Section 13.2.1 Equation 2. This accounts for silt loading tests conducted at the Facility, weight of vehicles using the road, and precipitation characteristics of the region to determine an emission factor in terms of pounds of particulate matter per vehicle mile traveled. The total vehicle miles traveled was calculated based on assumptions of the annual throughput and the capacity of the haul trucks. Fugitive particulate emissions from unpaved roads were calculated using Equations 1a and 2 of AP-42 Section 13.2.2.2. A control efficiency of 80% was assumed when implementing control measures such as a Facility wide speed limit of 15 miles per hour and application of water or other chemical dust suppressant. These control measures were therefore implemented into the permit. An emission factor in terms of pounds of particulate per day per acre of stockpile was obtained from the EPA’s report on Control of Open Fugitive Dust Sources, September 1988. The number, location, and size of


the piles at the site fluctuate throughout the year so a variability factor of 2 was conservatively added to the estimated pile sizes. Many of the stockpiles are made directly after the wash plant so the minimum moisture content typically exceeds 1.5%. Minimum moisture content limits were added to COMG 8 – Stockpiles. For purposes of the emission calculations, the Facility has conservatively not accounted for additional control of fugitive emissions due to the moisture content of the material. Truck loading and unloading of material is accomplished through front end loaders, which create fugitive particulate emissions. AP-42 Section 11 emission factors were used along with annual throughputs from the various facility material throughputs to conservatively estimate PTE. The HMA silo filling and truck loadout fugitive source used AP-42 Section 11 emission factors along with hourly and annual throughput limits from the HMA plant. Due to the nature of this permit, not all equipment are currently onsite or active and the ability to switch pieces of equipment in and out as long as its allowed by the permit requirements, it would be impossible to correctly label the equipment numbers on the actual excel calculation sheet. The Permittee is required however to maintain an equipment inventory list stating what is active/inactive/new etc. on site and this will be used when amendments come in and updated in TEMPO at that time. Attachment 4 shows the process flow diagrams for each spread (main sand & gravel, recycled, bituminous, screening, and hot mix asphalt).

3.2 Monitoring

In accordance with the Clean Air Act, it is the responsibility of the owner or operator of a facility to have sufficient knowledge of the facility to certify that the facility is in compliance with all applicable requirements.

In evaluating the monitoring included in the permit, the MPCA considered the following:

· the likelihood of the facility violating the applicable requirements; · whether add-on controls are necessary to meet the emission limits; · the variability of emissions over time; · the type of monitoring, process, maintenance, or control equipment data already available for the

emission unit; · the technical and economic feasibility of possible periodic monitoring methods; and · the kind of monitoring found on similar units elsewhere.

Table 5 summarizes the monitoring requirements.

Pressure Drop >=2 and <= 8 in. H2O [Minn. R. 7011.0917; limit to avoid NSR and Part 70] PM/PM10/PM2.5 >= 99% control efficiency. [limit to avoid NSR and Part 70]

Monitoring; O&M Plan; Corrective Actions; Periodic Inspections;

The Permittee is required to record the pressure drop for this unit. If the pressure drop is not within range then corrective actions will be taken until the pressure drop is back within range. The Permittee is required to do periodic inspections of the baghouse as defined in the permit requirement to ensure the baghouse components are functioning properly.

*Location of the requirement in the permit (e.g., EQUI0000000001, STRU0000000002, etc.).

3.3 Insignificant activities Tiller Corp - Maple Grove Mining & Processing Facility has several operations which are classified as insignificant activities under the MPCA’s permitting rules. These are listed in Appendix A to the permit. The permit is required to include periodic monitoring for all emissions units, including insignificant activities, per EPA guidance. The insignificant activities at this Facility are only subject to general applicable requirements. Using the criteria outlined earlier in this TSD, the following table documents the justification why no additional periodic monitoring is necessary for the current insignificant activities. See Attachment 1 of this TSD for PTE information for the insignificant activities. Table 6. Insignificant activities

Insignificant activity General applicable emission limit Discussion

Gasoline storage tanks with a combined total tankage capacity of not more than 10,000 gallons

PM, variable depending on airflow Opacity <= 20% (Minn. R. 7011.0710/0715)

The Permittee has one 3,000 gallon gasoline/solvent storage tank.


Insignificant activity General applicable emission limit Discussion

Brazing, soldering or welding equipment


The Permittee has stated that they have welding equipment.

Individual units with potential emissions less than 2000 lb/year of certain pollutants

PM ≤ 0.40 lb/MMBtu, or variable depending on airflow Opacity ≤ 20%, except for one 6-min period per hour of not more than 60% (Minn. R. 7011.0510/0515/0710/0715)

The Permittee has a portable propane –fired belt heater (0.3 MMBtu/hr capacity), (1) 15000 Btu/hr propane heater, 0.3 MMBtu/hr propane maintenance shop burn tables, 0.6 MMBtu/hr natural gas maintenance shop boilers, 0.165 MMBtu/hr natural gas maintenance shop space heaters, 0.36 MMBtu/hr natural gas pressure washers, (2) natural gas air make-up units 0.44 MMBtu/hr and 1.15 MMBtu/hr, (1) diesel generator for portable lights (0.124 Btu/hr), and (2) natural gas roof top units (0.11 and 0.15 MMBtu/hr capacities). The Permittee also has a wash plant, asphalt cement tank (40,000 gal), one used/waste oil aboveground storage tank (20,000 gal), and 2 used/waste oil underground storage tanks (10,000 and 5000 gal respectively).

Fugitive dust emissions from unpaved entrance roads and parking lots

Requirement to take reasonable measures to prevent PM from becoming airborne (Minn. R. 7011.0150)

The Permittee has fugitive dust from unpaved roads and from parking lots. The Permittee has prepared a fugitive dust control plan to take reasonable measures to prevent PM from becoming airborne.

Infrequent use of spray paint equipment for routine housekeeping or plant upkeep activities not associated with primary production processes at the stationary source


The Permittee performs touch-up painting around the facility and is unlikely to violate the applicable limits.

3.4 Permit organization

In general, the permit meets the MPCA Tempo Guidance for ordering and grouping of requirements. One area where this permit deviates slightly from Tempo guidance is in the use of appendices. While appendices are fully enforceable parts of the permit, in general, any requirement that the MPCA thinks should be electronically tracked (e.g., limits, submittals, etc.), should be in the Requirements table in Tempo. The main reason is that the appendices are word processing sections and are not part of the electronic tracking system. Violation of the appendices can be enforced, but the computer system will not automatically generate the necessary enforcement notices or documents. Staff must generate these.

3.5 Comments received Public Notice Start Date: September 22, 2017 Public Notice End Date: October 23, 2017 No comments were received from the public or EPA during the public notice period. The Permittee provided comments during the public notice period; these can be found in Attachment 5, with MPCA’s response.


· Two comments addressed grammatical errors in the title page and facility description. Those were fixed.

· One comment addressed the format of NESHAP ZZZZ and Subpart A for the engine. The requirements were not changed as it is the format the MPCA is using when no profiles are available.

· One comment addressed the requirement to comply with the fugitive emissions control plan. This requirement was updated to reflect the current profile language. The change in the requirement addressed the Permittee’s concern.

· One comment addressed the daily recordkeeping requirement for the recycled concrete & asphalt spread. One of the daily requirements incorrectly required a coarse angularity test, rather than the use of belt scales, which is the recordkeeping method used for other sources at the facility. This change in recordkeeping requires the permit action to go through public notice again.

4. Permit fee assessment

This permit action is the issuance of a state operating permit based on an application received September 6th, 2016. Even though the Permittee previously held a Nonmetallic Mineral General Permit, this action is not considered a reissuance of an individual state or Part 70 operating permit; therefore, the application fees apply under Minn. R. 7002.0019. Attachment 3 to this TSD contains the MPCA’s assessment of Application and Additional Points used to determine the permit application fee for this permit action as required by Minn. R. 7002.0019.

5. Conclusion

Based on the information provided by Tiller Corp - Maple Grove Mining & Processing Facility the MPCA has reasonable assurance that the proposed operation of the emission facility, as described in the Air Emission Permit No. 05301255-101 and this TSD, will not cause or contribute to a violation of applicable federal regulations and Minnesota Rules.

2. In the facility description under Item 3, please remove either “MN” or “Minnesota,” as it is currently a duplicate.

3. S.I. Reqt. 5.1.3 (Comply with Fugitive Emissions Control Plan) states the following:

“The plan may be amended by the Permittee with the Commissioner’s approval.” Tiller would like to remove this language stating that they must get the Commissioner’s approval to update the plan.

4. S.I. Reqt. 5.3.8 references the use of the Coarse Aggregate Angularity test. Per

discussions between Tiller, Trinity, and the MPCA, the use of this test is no longer needed due to the updated annual throughput limit in the Recycled Asphalt spread. As such, Tiller requests the removal of the language referring to this test. Please see requested language, below.

a. Daily Recordkeeping: On each day of operation, the Permittee shall calculate, record, and maintain the recycled material throughput for the recycled concrete & asphalt spread in tons for the previous day of operation. This shall be based on the use of belt scales [Minn. R. 7007.0800, subp. 2, Minn. R. 7007.3000, Title 1 Condition: Avoid major source under 40 CFR 52.21(b)(1)(i), To avoid major source under 40 CFR 70.2 & Minn. R. 7007.0200]

5. S.I. Reqt. 5.14.8 and 5.14.9 list the specific applicable requirements for 40 CFR Part 63, Subpart ZZZZ (NESHAP ZZZZ) and Subpart A. However, Tiller noticed that the requirements listed here do not match the highlighted regulatory review that was provided in the initial application. In order to avoid confusion and simplify the language in the permit , Tiller would prefer to see the following language rather than listing each specific requirement:

a. The permittee must comply with all applicable requirements of 40 CFR Part 63, Subpart ZZZZ. A copy of 40 CFR pt. 63, subp. ZZZZ is included in Appendix C. If the standard changes or upon adoption of a new or amended federal applicable requirement, and if there are more than 3 years remaining in the permit term, the Permittee shall file an application for an amendment within nine months of

mailto:[email protected]





promulgation of the applicable requirement, pursuant to Minn. R. 7007.0400, subp. 3. [40 CFR pt. 63, subp. ZZZZ, Minn. R. 7007.0400, subp. 3, Minn. R. 7007.1150-1500, Minn. R. 7011.81SO].

b. The permittee must comply with all applicable requirements of 40 CFR Part 63, Subpart A. A copy of 40 CFR pt. 63, subp. A is included in Appendix D. If the standard changes or upon adoption of a new or amended federal applicable requirement, and if there are more than 3 years remaining in the permit term, the Permittee shall file an application for an amendment within nine months of promulgation of the applicable requirement, pursuant to Minn. R. 7007.0400, subp. 3. [40 CFR 63.6665, 40 CFR pt. 63, subp. A, Minn. R. 7007.0400, subp. 3, Minn. R. 7007.1150·1500, Minn. R. 7011.8150].

If MPCA disagrees with this language update, Tiller requests that the following provisions be edited, as they do not apply to this unit.

1. S.I. Reqt. 5.14.8:a. Add the following condition:

i. 40 CFR Section 63.6630.b. Remove the following condition:

i. 40 CFR 63.6650(c)(6) – this condition applies to CEMS, which we will not have at the Maple Grove site.

ii. 40 CFR 63.6655(b) and (c) – these conditions apply to CPMS and landfill gas/digester gas.

2. S.I. Reqt. 5.14.9:a. Add the following conditions:

i. 40 CFR 63.6(b)(1)-(4) ii. 40 CFR 63.7(a)(4)

6. Given the seasonality of the industry and the applicable reporting and testing

requirements which would go into effect soon after issuance of the draft permit, Tiller would prefer to begin operating under this permit on or after January 1, 2018. Would it be possible to issue the permit at your convenience, but make the effective date on/after January 1, 2018?

Please let us know if you have any questions, and if you are available to discuss these requested updates. Thank you!………………………………………………………………………………………………….Angie Wanger, CMManaging Consultant Trinity Consultants12445 55th Street North, Suite A2 | Lake Elmo, MN 55042

From: Van Der Wal, Michael (MPCA)To: "Angie Wanger"Subject: Reply to Tiller CommentsDate: Wednesday, October 25, 2017 10:21:00 AM

Thanks Angie for your comments. I have corrected/fixed items 1, 2, and 4 from your comments in the previous email. In regards to the fugitive emission control plan requirement, this requirement changed recently (2 weeks ago) to say: “Comply with Fugitive Emission Control Plan: The Permittee shall follow the actions and recordkeeping specified in the fugitive dust control plan in Appendix [x] of this permit. If the Commissioner determines the Permittee is out of compliance with Minn. R. 7011.0150 or the fugitive control plan, then the Permittee may be required to amend the control plan and/or to install and operate particulate matter ambient monitors as requested by the Commissioner.” So I will be updating it to say this language. Hope this will solve the issue with the comment. As far as the NESHAP ZZZZ and Subpart A requirements go, this is a new approach that the MPCA is using if there isn’t already language within our TEMPO database for a given NESHAP or NSPS. This format will not be changed. It may not match the initial application highlighted sections due to the fact that either some of the highlighted sections didn’t need to be highlighted or some areas were missed being highlighted. Thanks,Michael
