3. Facility description
The Enviro-Chem Inc - Plant 1 (Facility) is located at 21821 Industrial Boulevard in Rogers, Hennepin County, Minnesota. Enviro-Chem operates six incinerator units that combust film to recover the silver. These units qualify as Class IV waste combustors. Film is combusted three times a week (one day of incineration followed by one day of cooling). After about a month, the silver-rich ash is collected from the incinerators and sold. The incinerators are ducted into a baghouse. The main pollutants of concern are particulate matter (PM), particulate matter 10 micrometers or less in diameter (PM10), particulate matter 2.5 micrometers or less in diameter (PM2.5), carbon monoxide (CO), and volatile organic compounds (VOCs). The incinerators are vented to afterburners to control CO and VOCs, and then are vented to a baghouse to control PM, PM10, and PM2.5. The smelting operations consist of three crucible furnaces. Miscellaneous metal scraps and metal powders are smelted to recover the precious metals and copper. The main pollutants of concern are PM, PM10, PM2.5, and VOCs. The smelting furnaces EQUI 10 and EQUI 12 vent to a baghouse (TREA 17) to control PM, PM10 and PM2.5.

Ash Management Plan & Mercury Separation Plan
Appendix C: Ash Management Plan
Ash Management Plan All ash generated from the waste combustion activities at ECI is considered a viable product. The ash contains a large amount of precious metals. The ash is pulled from the waste combustors and placed into steel containers for cooling. After 2-3 days of cooling, the ash is transferred into lined gaylord boxes and transported to metal recovery companies who further extract metals from the ash and pay ECI based on the recovery.
Appendix D: Mercury Waste Separation Plan
Mercury Waste Separation Plan All mercury containing material accepted by ECI is separated and placed in steel drums until an accumulation is ready to be sent to a proper mercury processing facility. Occasionally tests need to be run in Enviro-Chem’s laboratory operations in which samples of circuit boards are incinerated & smelted to gage metal contents on a laboratory scale. Some older circuit boards contain small amounts of mercury inside switches that ECI removes before processing. The laboratory operations are listed in the air permit application as an insignificant activity.

1.2 Facility description
Enviro-Chem operates six incinerator units that combust film to recover the silver. These units qualify as Class IV waste combustors. Film is combusted three times a week (one day of incineration followed by one day of cooling). After about a month, the silver-rich ash is collected from the incinerators and sold. The incinerators are ducted into a baghouse. The main pollutants of concern are particulate matter (PM), particulate matter 10 micrometers or less in diameter (PM10), particulate matter 2.5 micrometers or less in diameter (PM2.5), carbon monoxide (CO), and volatile organic compounds (VOCs). The incinerators are vented to afterburners to control CO and VOCs, and then are vented to a baghouse to control PM, PM10, and PM2.5. The smelting operations consist of three crucible furnaces. Miscellaneous metal scraps and metal powders are smelted to recover the precious metals and copper. The main pollutants of concern are PM, PM10, PM2.5, and VOCs. The smelting furnaces EQUI 10 and EQUI 12 vent to a baghouse (TREA 17) to control PM, PM10 and PM2.5.

1.6 Changes to permit The permit does not authorize any specific modifications, however, the MPCA has a combined operating and construction permitting program under Minnesota Rules Chapter 7007, and under Minn. R. 7007.0800, the MPCA has authority to include additional requirements in a permit. Under that authority, the following changes to the permit are also made through this permit action:
The permit has been updated to reflect current MPCA templates and standard citation formatting.
Completed requirements and the requirements for equipment that has been removed have been deleted.
EQUI 11 was removed from the permit because it has been removed from the facility.
COMG 2 was removed from the permit and the requirements for the smelting units were moved to EQUI 9, EQUI 10, and EQUI 12.
Baghouse (TREA 17) pressure drop range was changed to reflect the specification of the manufacturer.
Performance testing dates for cadmium, lead, and mercury were revised to align with the other required performance testing.

2. Regulatory and/or statutory basis 2.1 New source review (NSR)
The facility is a non-major source under the New Source Review program. No changes are authorized by this permit.
2.2 Part 70 permit program The Facility is a nonmajor source under the Part 70 permit program. Although PM PTE is over 100 tpy, PM is not considered a “regulated pollutant” within the definition of a major source in 40 CFR § 70.2. According to the EPA guidance document dated October 19, 1995, with subject line Definition of Regulated Pollutant for Particulate Matter for Purpose of Title V, written by Lydia N. Wegman, Deputy Director, a Title V operating permit is not required if the only pollutant that would make the source major is particulate matter.
2.3 New source performance standards (NSPS)
The Permittee states that no New Source Performance Standards apply to the operations at this facility. Per 40 CFR 60.2875, these incinerators are not subject to 40 CFR Subpart DDDD—Emissions Guidelines and Compliance Times for Commercial and Industrial Solid Waste Incineration Units.
2.4 National emission standards for hazardous air pollutants (NESHAP) The facility is an area source under 40 CFR pt.63. The Permittee states that no NESHAPS apply.

3. Technical information
3.1 Calculations of potential to emit (PTE) Attachment 1 to this TSD contains a summary of the PTE of the Facility, and contains detailed spreadsheets and supporting information prepared by the MPCA and the Permittee. Previous permit calculations methodology was deemed inappropriate and more appropriate calculations were drafted for this permit action. Incinerators Potential emissions from the natural gas incinerators (waste combustors) include emissions from the waste combustion process and from the combustion of the natural gas. To determine permit program applicability, the waste combustor rule PM limit of 0.035 gr/dscf was applied at each incinerator individuality. The airflow rate between the individual incinerators is unknown so the baghouse airflow measurement (in dscf) from the 2015 performance test plan was conservatively used. This method of calculating PTE is conservative and led to the facility having an unreasonably large growth in permit allowable PM emissions from the 2007 permit. No changes have been made to the facility so an emission limit was set for PM to maintain the permit allowable emissions to the same approximate levels as in the previous permit. This limit encompasses all emission units controlled by the baghouse which include the 6 incinerators and 2 smelters (EQUI 10 and EQUI 12). The emission limit of 2.0 lbs/hr for PM was set at the baghouse stack (STRU 1). It is highly unlikely that the facility can violate the limit. Potential emission rates for PM10, PM2.5, CO, Lead, Cd, and Hg were determined using emission factors from the results of the October 2015 and January 2016 performance tests. Permit requires testing for PM and emission factors for PM10 and PM2.5 assume PM = PM10 = PM2.5. The largest tested values from these tests multiplied by a safety factor of 20% were used. These results are conservative as they represent all waste combustors being run at maximum capacity but are applied to each waste combustor individually for CO, PM10, PM2.5, Lead, and Cd. The performance test results are used only for the waste combustors and are conservative as natural gas combustion is likely occurring during the performance test. These emission factor will have to reevaluated during the next permit action as performance testing in 2025 will also include emissions from smelting units (EQUI 10 and 12). Emissions from the combustion of natural gas from each of these units are based on their maximum fuel combustion capacity. Natural gas and GHG emission factors are from AP-42 chapter 1.4. Emissions for selenium and nickel are based on ash testing. No information about fabric filter control efficiencies for HAP’s were provided by the Permittee so it was assumed that there are none.
Technical Support Document, Permit Number: 05300411-101 Page 5 of 13
Smelting Potential emissions for PM, PM10, PM2.5, VOCs, and SO2 are calculated using the furnace capacity and AP-42 values for Secondary Copper Production - /Crucible and Pot Furnace, Charge with brass and bronze. This is a reasonable assumption for this operation as copper is the main metal recovered. The smelting operations are a batch process, according to Enviro-Chem, three hours is the shortest timeframe for each melt, resulting in a conservative assumption for emission calculations. PTE calculations for Mercury, Nickel, and Selenium are based on the results from previous ash testing. The record of the testing is not clear so values submitted by the Permittee will be used in this permit action and reevaluated after the next ash test in 2020. EQUI 10 and EQUI 12 are to be operated in certified hoods and emissions are ducted to the baghouse (TREA 17) and are accounted for under the PM emission limit set at the stack. As of the date of permit issuance, these hoods are in the process of being certified with a permit requirement for the process to be completed within 30 days. EQUI 9 is not operated in a certified hood and emissions are assumed to vent internally at the facility. Insignificant Activities There are five natural fired heaters, a natural gas fired office furnace, a natural gas fired make-up air unit and a natural gas fired water heater at the facility that qualify as insignificant activities under MN. R. 7007.1300 Subpart 3(f). Natural gas emission factors were obtained from AP-42 Chapter 1.4. There is also a Small hammermill/screening operation for grinding silver oxide batteries. An emission factor could not be located for a battery grinding in a hammermill. Therefore, a conservative assumption was that the battery hammermill particulate emissions are similar to Crushed Stone Fines Crushing. AP-42 Table 11.19.2-2 details emission factors for Fines Crushing.
3.2 Mercury Rule
In 2015 Enviro-Chem received a notice that it appeared to be a “mercury emission source” based on the MPCA’s 2011 Air Toxics Inventory. This source is no longer a mercury emissions source as its actual mercury emissions have been under the 3 lb/yr threshold since 2014 as required by Minn. R. 7007.0502. Actual mercury emissions listed in table 6 are from the facility’s annual emission inventory. Table 6. Actual Mercury Emissions

Mercury Emissions (lbs)
3.86 5.60 4.75 2.99 0.24 0.18 0.15 0.18
3.3 Removal of Silver Precipitation Operation from Permit
Enviro-chem uses an evaporator to remove water from spent cyanide solution that it receives from vendors. The solution received is approximately 3 vol% Potassium Silver Cyanide solution, and the balance of the solution is greater than 96.5 vol% water. This solution is fed to an evaporation vessel, where heat is added and the water is evaporated away. Potassium Silver Cyanide is soluble in liquid water, but not as a vapor. As the water is evaporated away, the Potassium Silver Cyanide remains behind in a sludge that is then sold for the silver content. This process hasn’t been used since 2016 but the equipment is also used for gold recovery operations. As the only emissions from this process is water vapor, this activity was removed from the insignificant activities list.
3.4 Removal of Gold Precipitation Operation from Permit
Enviro-chem uses a precipitation tank and the same evaporator from the silver recovery operation to reclaim gold from spent cyanide solution. The solution received is approximately 1.5 vol% Potassium Gold Cyanide solution, and the balance of the solution is greater than 98 vol% water. This solution is transferred to a precipitation tank where aluminum powder is added to precipitate out the gold. The solution is strained to remove the precipitant and fed to an evaporation vessel. Potassium Gold Cyanide is soluble in liquid
Technical Support Document, Permit Number: 05300411-101 Page 6 of 13
water, but not as a vapor. As the water is evaporated away the Potassium Gold Cyanide remains behind in a sludge that is sold for the gold content. This process is used infrequently. As the only emissions from this process is water vapor, this activity was removed from the permit.

3.6 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 8 summarizes the monitoring requirements.

Recordkeeping
Emissions from these units include both process emissions and natural gas combustion emissions. These units use natural gas; therefore, the likelihood of violating either of the emission limits is very small. The Permittee can demonstrate that these units will continue to operate such that emissions are well below the emission limits by only burning natural gas.
Design based PTE for EQUI 9, using AP-42, is 0.21 lbs/MMBtu of PM compared to the rule limit of 0.4 lbs/MMBtu of PM.
EQUI 10 and 12 are required to vent to a baghouse (TREA 17). Therefore, the control efficiency and associated monitoring ensure the limits can be met.

Performance testing
TREA 17 is the sole contributor to STRU 1. TREA 17 controls all six incinerators and smelting units EQUI 10 and EQUI 12. The highest 2015 PM performance test results for the incinerators (0.15lb/hr) and the PTE for EQUI 10 (0.22 lb/hr) and EQUI 12 (0.13lb/hr) suggest that the facility will meet this limit. Combined these emissions are 0.50 lb/yr which is 25% of the permit limit. This limit relies on TREA 17’s 99% PM control efficiency. All associated monitoring and recordkeeping for TREA 17 and performance testing on a 60-month frequency are adequate to have a reasonable assurance of compliance.

3.7 Insignificant activities
Enviro-Chem Inc - Plant 1 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 9. Insignificant activities

Notes: 1. AIRS emission factor for Secondary Copper Production - Crucible & Pot Furnace, Charge w/brass and bronze was used to calculate potential emissions from the smelting furnaces.2. The baghouse dust was analyzed for TCLP metal contents. The results indicated 0.00071% Lead, 0.029% Cadmium, 0.000012% Mercury, 0.00083% Nickel, and 0.0000074% Selenium.3. Furnace capacities are based upon the following: EQUI9 Capacity =30 lb. Minimum Melt Cycle = 3 hrs. EQUI10 Capacity = 300 lb. Minimum Melt Time = 3 hrs. EQUI12 Capacity = 175 lb. Minimum Melt Time = 3 hrs.
4. EQUI 10 and EQUI 12 vent to baghouse and are subject to PM emission limit set at STRU 1 (see Incinerator emissions tab)
5. Controlled PM calculated to demonstrate compliance with Minn. R. 7011.0550 Table II: New Indirect Heating Equipment

Notes:1. Emission factors could not be found specifically for hammermill grinding and screening. Therefore, it is assumed that these activities are similar to Crushed Stone Fines Crushing and Screening, and emission factors from AP-42 Table 11.19.2-2 are being used.2. The silver oxide button cell batteries can contain up to 40% maganese oxide.3. Maximum capacity is 10/lb/min. Enviro-Chem states that they operate the equipment at approximately 3 lb/min4. This activity qualifies as an insignificant activity under Minn. R. 7007.1300 Subpart 3(F).
