Mayasich Phone: 2187223336 1.2 Facility Description Western Lake Superior Sanitary District (WLSSD) is a publicly owned treatment works whose primary function is to treat municipal and industrial wastewater. The facility also includes household hazardous waste collection. The facility is located in Duluth, St. Louis County, Minnesota. The wastewater treatment facility was constructed between 1975 and 1978. The plant officially began operations in January of 1979. The plant provides advanced secondary treatment to domestic and industrial wastewater from ten municipalities and three major wood product industries. Wastewater is collected by an extensive interceptor system. The municipalities serviced are in St. Louis and Carlton Counties and include the cities of Duluth, Cloquet, Carlton, Esko, (Thomson Township), Scanlon, Wrenshall, Hermantown, Proctor, and Thompson. WLSSD treats an average daily flow of wastewater of approximately 43 million gallons per day (MGD). The facility was designed to handle a peak flow of 87 MGD. Municipal customers account for 50 percent (at 43 MGD) of wastewater flow received by the facility with industry contributions accounting for the remaining inflow to the facility. The wastewater treatment facility generates an average of 200 wet tons (moisture content of approximately 94 to 95 percent) of sewage sludge each day. The sludge is currently treated with digesters. The anaerobic digesters biologically decompose the sludge, producing a product that is sufficiently stable for storage and application to land. The byproducts of anaerobic digestion are methane (CH 4 ), carbon dioxide (CO 2 ), and small amounts of nitrogen, hydrogen, hydrogen sulfide (H 2 S) and water. The permit requires the digester gas to be routed to a combustion device. Pollutants of concern are nitrogen oxides (NO x ), carbon monoxide (CO), and CO 2 from combustion and CO 2 , CH 4 , and H 2 S from anaerobic digestion. The facility is an existing major source under Federal Operating Program (40 CFR Pt. 70), an area source under Federal Operating Program (40 CFR pt. 63), and minor source New Source Review/Prevention of Significant Deterioration (NSR/PSD).

 1.2 Facility Description Western Lake Superior Sanitary District (WLSSD) is a publicly owned treatment works whose primary function is to treat municipal and industrial wastewater. The facility also includes household hazardous waste collection. The facility is located in Duluth, St. Louis County, Minnesota. 

The wastewater treatment facility was constructed between 1975 and 1978. The plant officially began operations in January of 1979. The plant provides advanced secondary treatment to domestic and industrial wastewater from ten municipalities and three major wood product industries. Wastewater is collected by an extensive interceptor system. The municipalities serviced are in St. Louis and Carlton Counties and include the cities of Duluth, Cloquet, Carlton, Esko, (Thomson Township), Scanlon, Wrenshall, Hermantown, Proctor, and Thompson. 

WLSSD treats an average daily flow of wastewater of approximately 43 million gallons per day (MGD).  The facility was designed to handle a peak flow of 87 MGD. Municipal customers account for 50 percent (at 43 MGD) of wastewater flow received by the facility with industry contributions accounting for the remaining inflow to the facility. 

The wastewater treatment facility generates an average of 200 wet tons (moisture content of approximately 94 to 95 percent) of sewage sludge each day. The sludge is currently treated with digesters. The anaerobic digesters biologically decompose the sludge, producing a product that is sufficiently stable for storage and application to land.  The by‐products of anaerobic digestion are methane (CH4), carbon dioxide (CO2), and small amounts of nitrogen, hydrogen, hydrogen sulfide (H2S) and water.  The permit requires the digester gas to be routed to a combustion device. 

Pollutants of concern are nitrogen oxides (NOx), carbon monoxide (CO), and CO2 from combustion and CO2, CH4, and H2S from anaerobic digestion. The facility is an existing major source under Federal Operating Program (40 CFR Pt. 70), an area source under Federal Operating Program (40 CFR pt. 63), and minor source New Source Review/Prevention of Significant Deterioration (NSR/PSD).

 2. Regulatory and/or Statutory Basis  New Source Review (NSR) The facility is a true minor source for PSD. The anaerobic digesters cannot produce enough digester gas to fire all the units at the same time. For this reason, the PTE is based on the combustion of available digester gas. The existing digester gas boiler and two heating boilers will be replaced by three digester gas boilers and seven heating boilers. After this amendment, the facility still remains below major NSR/PSD thresholds.    The facility’s unrestricted PTE for greenhouse gases (measured as carbon dioxide equivalent, CO2e) is above the major source threshold for NSR/PSD. The digester gas produced in the digesters consists primarily of CO2 and CH4. All digester gas must be routed through a combustion device. After combustion of the methane, the CO2e PTE is below the major source PSD thresholds. The Supreme Court’s June 23, 2014 decision determined that the EPA will no longer apply or enforce federal regulations solely because the source emits or has the potential to emit GHG’s above the major source

 With the addition of the high strength waste, the four digesters can produce a maximum of 41,633 scf/hr of digester gas. This is not enough digester gas to fire all possible units at the same time. The flares (EUs 054 and EU 076) each have the capacity to combust 42,000 scf/hr of digester gas, the three engines have a total digester gas firing capacity of 43,400 scf/hr and the three digester gas boilers have a total digester gas firing capacity of 33,000 scf/hr.   The limited PTE calculations include operation of just one flare (existing or temporary) or the three engines when calculating the total facility PTE since there is only enough digester gas to completely fire one flare (temporary or existing) or the three engines at a time. The worst case emissions on a pollutant to pollutant basis were used for these units. The digester gas boilers can fire both digester gas and natural gas as a backup fuel. For PTE purposes, the digester gas boilers are assumed to be firing natural gas and the digester gas is assumed to be combusted in either the engines or the flares.    3.2 Equipment Shut Down and Removal The two existing heating boilers and the current digester gas boiler (EU 050‐052) will be permanently shut‐down/decommissioned. The boilers are subject to all applicable requirements listed in the permit until they are permanently shut‐down. A Notification of the Date of Equipment Removal/Dismantlement shall be submitted for each unit within 15 days of removal/dismantlement. For this permit, removal shall mean the same thing as shut‐down.  The Permittee will be decommissioning the units by either disconnecting the water/steam lines or disconnecting the fuel lines to demonstrate that the equipment is inoperable. The final decision on whether the equipment will be removed from the site has not yet been made.  The equipment will not be modified and will not be operated in the future.   Once EUs 050‐052 have been shut‐down/decommissioned, they will no longer be subject to the requirements listed in the permit. The permit language and applicable requirements for EUs 050‐052 will be removed from the permit during the permit action following the shut‐down/decommission of the boilers.   3.3 Performance Testing 40 CFR pt. 60, subp. JJJJ requires performance testing to assure compliance with the NOx, CO, and VOC limits set within the standard for each of the three digester gas engines (EUs 073‐075). An initial performance test shall be completed to show compliance with each pollutant for each engine. The initial performance test shall be completed within 60 days of the engine reaching maximum capacity, but no later than 180 days after initial engine startup. As required by the standard, testing frequency after the initial performance test shall be completed before the end of each calendar 36 months following the initial performance test or every 8760 operating hours, whichever comes first.   A performance test report shall be submitted for each performance test. Minnesota rule (Minn. R. 7017.2035, subp. 2) requires a performance test report to be submitted within 45 days following the completion of the performance test. Federal rule (40 CFR Section 60.4245(d)) requires a copy of each performance test to be submitted within 60 days following the completion of the performance test. Submitting the performance test within 45 days of completion of the performance test will satisfy both the state and the federal requirement.

 Group 010, Heating Boilers – 5 mmBtu/hr: This group has been created and contains requirements for the seven new heating boilers.  The new heating boilers are not subject to requirements under 40 CFR pt. 60, subp. Dc.   EU 050, Digester Gas Boiler: The emission unit is being decommissioned and removed from the permit with this major amendment. All applicable permit limits, requirements, and submittals for EU 050 will remain in the permit until shut‐down of the unit. Upon shut‐down of the emission unit, the limits, requirements and submittals will no longer be applicable and will be removed from the permit at the following permit action.   The citation for the sulfur content of fuel limit was incorrect and was updated appropriately.   EU 072, Digester Gas Pretreatment System: The digester gas treatment system (EU 072) purifies the digester gas prior to combustion. The treatment system consists of three separate stages; a bio‐filter to remove H2S, a water knock‐out stage, and a siloxane removal stage.  During the siloxane regeneration cycle, air is blown through the siloxane treatment system which regenerates the siloxane removal media. This regenerative air flow is considered process gas. Since the process gas does not have the energy capacity to sustain combustion, either natural gas or digester gas is added to the process gas stream and is combusted in an internal flare – the digester treatment flare.   3.5 Construction Authorization and Notifications The Permittee is authorized to install and operate EUs 062‐064 (digester gas boilers), EUs 065‐071 (heating boilers), EU 072 (digester gas treatment flare and bio‐filter), EUs 073‐075 (digester gas engines), and EU 076 (temporary digester gas flare). The Permittee shall commence construction within 5 years of the issuance of permit no. 13700112‐009. An extended timeframe of five years was selected since the facility is a municipality and is planning on constructing the units in two phases over the next several years. The boilers will be installed in phase one and the engines will be installed in phase two.   Notifications of commenced construction need to be submitted within 30 days of the date construction began for all units. Construction is as defined in Minn. R. 7007.01000, subp. 5.   Notifications of initial startup need to be submitted within 15 days of initial startup for all units. Startup is as defined in Minn. R. 7005.0100, subp. 42a. Initial equipment testing during installation does not constitute startup for production/operation purposes. The engines require additional information in accordance with 40 CFR pt. 60, subp. JJJJ.   The temporary flare will be contractor owned and only be onsite for the construction process. A notification of the date of removal of the temporary flare will be needed within 15 days of the date it was removed.   3.6 Dispersion Modeling A SCREEN 3 analysis was completed for the three digester gas engines (EUs 073‐075). All three engines were modeled as merged stack, as defined in the Minnesota Pollution Control Agency Air Quality Modeling Guidance. Since the final make and model of the engines has not been determined, the stack

diameter, exhaust temperature, exhaust concentration, and exhaust velocity used in the analysis were worst case modeled concentrations. The SCREEN 3 modeling analysis showed that the facility modeled compliance with ambient air impact target levels for all modeled pollutants.  A detailed summary of the SCREEN 3 analysis can be found in Attachment 4 of this TSD. Table 6 shows SCREEN 3 ambient impact results of the three engines.

 Based on the SCREEN 3 screening model output provided for the Western Lake Superior Sanitary District (WLSSD) the facility should comply with all the applicable ambient air quality standards. The only pollutant that seemed high was NO2. The numeric value of the short‐term NO2 NAAQS is 188 micrograms per cubic meter (μg/m3). The NO2 modeled concentration was 179.89 μg/m3.  The MPCA does not require further modeling for WLSSD at this time. The rationale for this conclusion is based on the conservative nature of the SCREEN 3 screening model. It is designed to overestimate predicted concentrations to better protect the NAAQS by providing the highest single predicted concentration under simulated meteorological conditions to generate the output. Additionally, the PTE used in the SCREEN 3 analysis was based on the engines fuel combustion capacity, rather than the digester gas production capacity. The digesters cannot produce enough gas to operate all three engines at maximum capacity at the same time, which makes the analysis even more conservative.  Based on the stand‐alone value as reported for this project, the MPCA believes that the facility will comply with the applicable NAAQS.   3.7 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.

Requirement (rule basis)  Monitoring  Discussion 

EU 072 (Digester Gas Treatment Flare) 

PM: ≤ 0.30 grains/dry standard cubic foot of exhaust gas; Opacity: ≤ 20 %  (Minn. R. 7011.0610) 

None Based on equipment design and fuel type (process gas, digester gas, and natural gas) the likelihood of violating either limit is very small. The flare’s PTE of PM is 0.0006 grains/dry standard cubic foot where the limit at maximum airflow is 0.10 grains/dry standard cubic foot. 

*Location of the requirement in the permit (e.g., EU, SV, GP, etc.).  3.8 Insignificant Activities Western Lake Superior Sanitary District has several operations which are classified as insignificant activities under the MPCA’s permitting rules. These are listed in Appendix B to the permit. There are no additional insignificant activities included in this modification.   3.9 Permit Organization  In general, the permit meets the MPCA Delta Guidance for ordering and grouping of requirements. One area where this permit deviates slightly from Delta guidance is in the use of appendices. While appendices are fully enforceable parts of the permit, in general, any requirement that the MPCA thinks should be electronically tracked (e.g., limits, submittals, etc.), should be in Table A or B of the permit. The main reason is that the appendices are word processing sections and are not part of the electronic tracking system. This permit uses an appendix to list the insignificant activities.  Another area that deviates from the guidance is in the use of groups where the requirements in the group apply to the members of the group individually. This was done in order to shorten the permit. This is the case for the requirements in GP 003 (Heating Boilers‐800 hp), GP 005 (Anaerobic Digesters), GP 007 (Digester Gas Boilers), GP 008 (Digester Gas Engines), GP 009 (Flares), and GP 010 (Heating Boilers‐5.5 mm Btu/hr).  3.10 Comments Received Public Notice Period: <start date> ‐ <end date> EPA 45‐day Review Period: <start date> ‐ <end date>  This section will be completed after the 30‐day public notice period and the 45‐day EPA review period.    4. Permit Fee Assessment Attachment 3 to this TSD contains the MPCA’s assessment of Application and Additional Points used to determine the permit application fee for this permit action as required by Minn. R. 7002.0019. The permit action is a major amendment which includes the incorporation of 40 CFR pt. 63, subp. JJJJJJ; 40 CFR pt. 63, subp. ZZZZ; and 40 CFR pt. 60, subp. JJJJ. Each NESHAP and NSPS was worth 10 points for a total of 30 points. The SCREEN 3 modeling was completed but does not trigger any points.    5. Conclusion Based on the information provided by Western Lake Superior Sanitary District, the MPCA has reasonable assurance that the proposed operation of the emission facility, as described in the Air Emission Permit

NOx, CO, and VOC emission factors obtained from 40 CFR 60 Subpart JJJJ, Table 1 for digester gas engines.

Digester gas engine NSPS limits do not vary by size or rich/lean burn for model years 2011 and later.

Emission limits converted to lb/MMBtu factors by multiplying by maximum engine bhp and dividing by

maximum engine fuel consumption in MMBtu/hr.

PM emission factor is total of condensable and filterable PM, from AP-42, Table 3.2-3, July 2000, for

4-stroke, rich burn engines (natural gas).

Digester gas sulfur content converted from ppm to lb/MMBtu assuming ideal gas density of 387 ft3/lb-mole:

The engines can burn up to 43,416 scf/hr of digester gas, however, the digesters can only produce 41,633scf/hr of

digester gas. The PTE for engines was conservatively calculated at the engines capacity rather than the digester

gas production rate.

SO2 EF = (ppm H2S/1000000) x (1 lb-mole H2S/387 ft3 H2S) x (1 lb-mole SO2 / 1 lb-mole H2S)

x (64 lbs SO2 / 1 lb-mole SO2) / (663.0 Btu/cf x MMBtu/1,000,000 Btu) = 0.249 lb/MMBtu

Exit gas temperatures were approximated. Digesters operate at 98o F at the end of the process. Flares operating range 1000-2000o F

Digester gas can exit multiplpe stacks, airflow was assumed to be total digester gas production

Process Weight Rate: the amount of material that is processed by the equipment (paint/gelcoat/fuel), in pounds per hour.

IPER Limit: Whichever Limit from Table 1 or Table 2 is less stringent is the limit. However, if Table 1 is the less stringent limit, but results in a load of more

than 0.3 grains per dry standard cubic foot, then the limit is 0.3 grain per dry standard cubic foot

EU Process Weight Rate is assuming digester gas is 65% methane and 35% CO2. density of methane and CO2 used is 0.0417 lc/scf and 0.1150 lb/scf,
