MSD operates three (3) multiple hearth incinerators, namely Unit Nos. 1 through 3. The three sludge multiple hearth incinerators (11 hearths each) were installed in 1968. Each Incinerator has its own heat recovery boiler, and combination of impingement tray scrubber and fixed venturi scrubber. The exhaust from each incinerator and set of scrubbers is then directed to one exhaust stack. The sludge that is removed from the wastewater is sent to the sludge well where it is blended with accumulated solids taken from the grit and primary settling tanks. A polymer is added to the sludge to help coagulate the solids. The sludge is then sent to six belt presses to the pressroom. The belt presses are used to remove as much moisture from the sludge as possible prior to incineration. The ash from the incinerators is made into slurry and sluiced to ash lagoons off -site via two underground lines. Once the slurry reaches the lagoons, the water is decanted off. Ash is hauled to a landfill approximately once per year. Additional equipment on site includes two natural gas emergency generators, sand blaster, and one parts washer. Along with the heat recovery boilers, there are two natural gas auxiliary boilers that do not have back-up fuel. Also on site is a 550-gallon diesel underground storage tank (UST) and three 550-gallon (each) unleaded gasoline USTs. MSD-Lemay Plant is located in St. Louis County, a nonattainment area for the 8-hour ozone standard and the PM2.5 standard and an attainment area for all other criteria pollutants. MSD-Lemay Plant emits major levels of carbon monoxide (CO) and has the Potential to Emit (PTE) major amounts of nitrogen dioxide (NOx). MSD-Lemay Plant is not on the List of Named Installations found in 10 CSR 10- 6.020(3)(8), Table 2.

Permit Reference Documents These documents were relied upon in the preparation of the operating permit. Because they are not incorporated by reference, they are not an official part of the operating permit. 1) Part 70 Operating Permit Application, received May 26, 2005; revised May 29, 2013; 2) 2014 Emissions Inventory Questionnaire, received April 29, 2015; 3) U.S. EPA document AP-42, Compilation of Air Pollutant Emission Factors; Volume I, Stationary Point and Area Sources, Fifth Edition; 4) New Source Permit Amendment to Permit No. 5768, Project No. 2015-01-042, Issued March 11, 2015 for replacement the existing impingement tray scrubbers and single venturi scrubbers for incinerators #1 through #3 with combination impingement tray scrubbers and multiple fixed venturi scrubbers; 5) New Source Permit Amendment to Permit No. 5768, Project No. 2017-04-008, Issued August 21, 2017, for sewage sludge incinerator upgrade project which occurred in 2015-2016; and 6) New Source Review Permit Amendment, Project No. 2017-09-008, Issued October 3, 2017. Applicable Requirements Included in the Operating Permit but Not in the Application or Previous Operating Permits In the operating permit application, the installation indicated they were not subject to the following regulation(s). However, in the review of the application, the agency has determined that the installation is subject to the following regulation(s) for the reasons stated. 40 CFR Part 63, Subpart CCCCCC - National Emission Standards for Hazardous Air Pollutants for Source Category: Gasoline Dispensing Facilities. This rule has not been included in the renewal application; however, it has been determined to be applicable to the installation and, therefore, has been included in this operating permit. MSD - Lemay Wastewater Treatment Plant Part 7U Operating Permit SB - 3 Installation ID: 189-0217 Project No. 2005-06-025 Other Air Regulations Determined Not to Apply to the Operating Permit The Air Pollution Control Program (APCP) has determined the following requirements to not be applicable to this installation at this time for the reasons stated. 1) 10 CSR 10-5.330 Control of Emissions From Industrial Surface Coating Operations. This rule applies to certain installations from which actual emissions of VOCs from surface coating operations are greater than 3 tons per twelve (12)-month rolling period. While the maximum potential VOC emissions from the paint spray booths (EP10) are greater than 3 tons per year, the actual emissions are a few pounds. Therefore, CSR 10-5.330 is not applicable. 2) 10 CSR 10-5.520 Control of VOC Emissions from Existing Major Sources. This rule is not applicable to this installation, as it is not a major source of VOC emissions. 3) 10 CSR 10-6.260 Restriction of Emission of Sulfur Compounds and 10 CSR 10.6.261 Control of Sulfur Dioxide Emissions. These rules do not apply to the installation because the combustion equipment at this installation is fueled exclusively with natural gas and according to 10 CSR 10-6.260(1)(A)2. and 10 CSR 10-6.261(1)(A), combustion equipment that uses exclusively pipeline grade natural gas as defined by American Society for Testing and Materials (ASTM) is exempt. 4) 10 CSR 10-6.405 Restriction of Particulate Matter Emissions From Fuel Burning Equipment Used for Indirect Heating. This regulation does not apply to the boilers because they burn only natural gas and are exempt according to 10 CSR 10-6.405(1)(C). 5) 10 CSR 10-5.455 Control of Emission from Solvent Cleanup Operations This regulation applies to certain solvent cleanup operations at which cleaning solvent VOCs are emitted at 500 lbs/day or greater. Since the maximum potential VOC emissions from the parts washer (EP11) is less than 500 lbs/day and cold cleaning is exempted from this rule, 10 CSR 10- 5.455 is not applicable. Construction Permit History 1) New Source Permit Amendment to Permit No. 5768, Project No. 2015-U 1-042, Issued March 11, 2015: The permit amendment supersedes individual throughput limits of permit 5769, establishes a plant wide dry sludge throughput limit, and update the control equipment that is required to control incinerator emissions. 2) New Source Permit Amendment to Permit No. 5768, Project No. 2017-04-008, Issued August 21, 2017, for sewage sludge incinerator upgrade project which occurred in 2015-2016. This is an amendment to a previously issued St. Louis County Construction Permit #5768 for sewage sludge incineration units 1, 2, and 3 at the MSD Lemay WWTP, originally issued in 1969 and amended August 3, 1990 and March 11, 2015. This is the second amendment to permit 5768 for incinerators #1, #2, and #3 related to this scrubber upgrade project. This amendment performs two functions; supersede and re-establish previous plant wide dry sludge throughput rate limits, and establish incinerator control device requirements which incorporate and reference the operating parameter limits contained in 40 CFR Part 60 Subpart MMMM. A plant -wide sludge throughput limitation is re-established to demonstrate that there is no MSD - Lemay Wastewater Treatment Plant Part 70 Operating Permit SB - 4 Installation ID: 189-0217 Project No. 2005-06-025 increase in emissions or debottlenecking associated with the 2015-2016 scrubber upgrade project. The conditions of this permit supersede the following special conditions from previously issued permits: • All special conditions found in the previously issued construction permit amendment to #5768 with corresponding Project No. 2015-01-042 issued by the Saint Louis County Department of Public Health Air Pollution Control Program on March 11, 2015. • From Construction Permit 5768 amendment issued August 3, 1990, "One of the three (3) incinerators must be offline whenever incinerator #4 (OP 5365) is in operation." 3) New Source Review Permit Amendment, Project No. 2017-09-008, Issued October 3, 2017: This is an amendment to permit 5768 (issued August 31, 2017) to correct the language contained in Special Condition 2.A. by superseding Special Condition 2 and establishing a new condition which contains a specified time period for the plant -wide dry sludge throughput limit. New Source Performance Standards (NSPS) Applicability 10 CSR 10-6.070 New Source Performance Regulations The installation is potentially subject to several NSPS rules. Below is a summary of the potentially applicable subparts and the facilities applicability and compliance status to those subparts. 1) 40 CFR Part 60, Subpart A - General Provisions. The installation becomes subject to Subpart A - General Provisions upon becoming subject to an NSPS standard. If the installation is subject to various NSPS Standards; therefore, they are also subject to Subpart A. 2) 40 CFR Part 60 Subpart De - Standards of Performance for Small Industrial -Commercial - Institutional Steam Generating Units The provisions of this subpart apply to each fossil -fuel -fired steam generating unit of more than 73 megawatts heat input rate (250 million Btu per hour) constructed or modified after August 17, 1971 and not covered under Subpart Da. None of the boilers are rated at greater than 73 megawatts heat input rate (250 million Btu per hour), therefore this subpart does not apply to this installation. 3) 40 CFR Part 60, Subpart Da - Standards of Petformance for Electric Utility Steam Generating Units for Which Construction is commenced After September 18, 1978. The provisions of this subpart apply to each electric utility fossil -fuel (either alone or in combination with any other fuel) fired steam generating unit of more than 73 megawatts heat input rate (250 million Btu per hour) constructed or modified after September 18, 1978. None of the boilers are electric utility steam generating units as defined in this subpart nor are rated at greater than 73 megawatts heat input rate (250 million Btu per hour), therefore this subpart does not apply to this installation. 4) 40 CFR Part 60, Subpart Db - Standards of Performance for Industrial -Commercial -Institutional Steam Generating Units. The provisions of this subpart apply to each steam generating unit that commences construction, modification, or reconstruction after June 19, 1984, and that has a heat input capacity from fuels MSD - Lenny Wastewater Treatment Plant kart "/u operating Permit SB - 5 Installation ID: 189-0217 Project No. 2005-06-025 combusted in the steam generating unit of greater than 29 MW (100 million Btu per hour). None of the boilers are rated at greater than 29 megawatts heat input rate (100 million Btu per hour), therefore this subpart does not apply to this installation. 5) 40 CFR Part 60, Subpart Dc - Standards of Performance for Small Industrial -Commercial - Institutional Steam Generating Units. Subpart Dc applies to each steam generating unit for which construction, modification, or reconstruction is commenced after June 9, 1989 and that has a maximum design heat input capacity of 29 megawatts (MW) (100 million Btu/hr) or less, but greater than or equal to 2.9 MW (10 million Btu/hr). The boilers have heat input capacities of less than 100 MMBtu/hr but greater than 10 MMBtulhr and constructed in 1980 prior to the applicability date of the Subpart Dc, therefore these boilers are not subject to the provisions of this subpart. 6) 40 CFR Part 60, Subparts K - Standards of Performance for Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction Or Modification Commenced After June 11, 1973, and Prior to May 19, 1978. 40 CFR Part 60, Subpart Ka - Standards of Performance for Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction Or Modification Commenced After May 19, 1978, and Prior to July 23, 1984 The installation does not have any petroleum storage vessels as defined in these subparts that are subject to this regulation. 7) 40 CFR Part 60 - Subpart Kb, Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction Or Modification Commenced After July 23, 1984.

The emergency generator was manufactured on October 21, 2008 and construction commenced on June 23, 2008. As stated in 40 CFR §60.4230(a)(4)(iv) of Subpart JJJJ, the provisions of this subpart are applicable to owners and operators of emergency engines constructed on or after January 1, 2009. Since the emergency generator was constructed before the applicability date of this subpart, the provisions of this subpart are not applicable to the installation. 10) 40 CFR Part 60 Subpart O - Standards of Peifonnance for Sewage Treatment Plants The provisions of this subpart apply to each incinerator that combusts wastes containing more than 10 percent sewage sludge (dry basis) produced by municipal sewage treatment plants, or each incinerator that charges more than 1000 kg (2205 lb) per day municipal sewage sludge (dry basis) and that commences construction or modification after June 11, 1973. Since incinerators #1 through #3 were constructed in 1967, the requirements of this subpart would not apply. 11) 40 CFR Part 60 Subpart MMMM - Emission Guidelines and Compliance Times for Existing Sewage Sludge Incineration Units. This subpart applies to the existing incinerators (EP1 — Incinerator 1 -3) and the ash handling system (EP4). Maximum Achievable Control Technology (MACT) Applicability 10 CSR 10-6.075 - Maximum Achievable Control Technology Regulations. Section 112 of the Clean Air Act lists 187 hazardous air pollutants to be regulated by source category. EPA has identified "source categories" that must meet technology requirements to control HAP emissions and is required to develop standards for all industries that emit one or more of the HAPs in significant quantities. The standards are based on emissions levels already achieved by best- performing similar facilities. Industries subject to MACT standards are classified as either major sources or area sources. • Major sources are sources that emit 10 tons per year of any of the listed HAPs, or 25 tons per year of a mixture of HAPs. • Area sources are sources that emit less than 10 tons per year of a single HAP or less than 25 tons per year of a combination of HAPs. Area sources must employ Generally Available Control Technology (GACT) which is based on appropriate practices/ techniques commercially available and taking into account economic and technical considerations. MACT standards are applicable to major sources, while GACT standards are applicable to area sources. The installation has the potential to emit various HAPs. Based upon a comparison of the installation operations to each area source MACT/GACT Standard, the installation is potentially subject to the following MACT/GACT standards: (NOTE: This is not an analysis of every MACT/GACT standard, it is an analysis of the MACT/GACT standards that are potentially applicable to the installation) MSD - Lemay Wastewater Treatment Plant Part 70 Operating Permit SB - 7 Installation ID: 189-0217 Project No. 2005-06-025 1) 40 CFR Part 63, Subpart T - National Emission Standards for Halogenated Solvent Cleaning. The provisions of this subpart apply to each individual batch vapor, in -line vapor, in -line cold, and batch cold solvent cleaning machine that uses any solvent containing methylene chloride, perchloroethylene, trichloroethylene, 1,1,1-trichloroethane, carbon tetrachloride or chloroform, or any combination of these halogenated HAP solvents, in a total concentration greater than 5 percent by weight, as a cleaning andlor drying agent. Wipe cleaning activities, such as using a rag containing halogenated solvent are not covered under the provisions of this subpart. The maintenance cold cleaner unit does not use halogenated solvents as defined in 40 CFR 63.460, therefore the parts washer is not subject to the MACT standards for halogenated solvent cleaning. 2) 40 CFR Part 63 Subpart VVV - National Emission Standards for Hazardous Air Pollutants: Publicly Owned Treatment Works. The plant is considered an existing non -industrial source under this rule. As an existing non- industrial source, the plant does not have additional control requirements and is not required to submit a notification of compliance status under this subpart. 3) 40 CFR Part 63, Subpart MMMM - National Emission Standards for Hazardous Air Pollutants for Surface Coating of Miscellaneous Metal Parts and Products. This rule applies to a facility that owns or operates a miscellaneous metal parts and products surface coating operation that is a major source, or is located at a major source, or is part of a major source of HAP emissions. An affected source that uses 946 liters (250 gallons) per year, or more, of coatings that contain hazardous air pollutants (HAP) could be subject to this rule. The installation is an area source of HAP emissions and therefore is not subject to this subpart 4) 40 CFR Part 63, Subpart ZZZZ, National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines. The Subpart ZZZZ standards are applicable to Reciprocating Internal Combustion Engines (RICE) located at both major andlor area sources of hazardous air pollutants (HAPs) and RICE with a site rating of less than or equal to 500 brake horsepower (bhp). In addition, the standards for existing non -emergency compression ignition (CI) engines with a site rating of greater than 500 bhp at major sources and revised provisions related to Startup, Shutdown, and Malfunction (SSM) events for engines previously regulated under the rule. Finally, emergency RICE with a rating greater than 500 bhp located at a major source are subject to this rule, but with limited requirements. o The installation operates natural gas -fired 340 HP emergency generator (EP5) whose operations are limited to emergency situations. The engine was installed prior to June 12, 2006 and according to §63.6590(a)(1)(iii) of this subpart, stationary RICE located at an area source of HAP emissions is existing if commenced construction or reconstruction before June 12, 2006. The engine is subject to the Work Practice Standards, Maintenance Plan, Monitoring, and Recordkeeping requirements. Therefore, this subpart applies. o The natural gas fired spark ignition 895 KW internal combustion engine (emergency generator identified as EP16) manufactured on October 21, 2008 and construction commenced on June 23, 2008does not have any applicable requirement under this subpart. 5) 40 CFR Part 63 Subpart DDDDD - National Emission Standards for Hazardous Air Pollutants for Industrial, Commercial. and Institutional Boilers and Process Heaters. MSD - Lemay Wastewater Treatment Plant Part 70 Uperatmg Permit SB - 8 Installation ID: 189-0217 Project No. 2005-06-025 The Subpart applies to a facility that owns or operates a industrial boilers, institutional boilers, commercial boilers, and process heaters that is a major source, or is located at a major source, or is part of a major source of HAP emissions. A process heater is defined as a unit in which the combustion gases do not directly come into contact with process material or gases in the combustion chamber (e.g., indirect fired). A boiler is defined as an enclosed device using controlled flame combustion and having the primary purpose of recovering thermal energy in the form of steam or hot water. This regulation does not apply the boilers and heaters at this facility because the installation is an area source of hazardous air pollutants (HAPS).. 6) 40 CFR Part 63, Subpart CCCCCC - National Emission Standards for Hazardous Air Pollutants for Source Category: Gasoline Dispensing Facilities. The purpose of this subpart is to establish national emission limitations and management practices for hazardous air pollutants (HAP) emitted from the loading of gasoline storage tanks at gasoline dispensing facilities (GDF). The affected source to which this subpart applies is each GDF that is located at an area source. A gasoline dispensing facility (GDF) is any stationary facility which dispenses gasoline into the fuel tank of a motor vehicle, motor vehicle engine, nonroad vehicle, or nonroad engine, including a nonroad vehicle or nonroad engine used solely for competition. These facilities include, but are not Limited to, facilities that dispense gasoline into on- and off -road, street, or highway motor vehicles, lawn equipment, boats, test engines, landscaping equipment, generators, pumps, and other gasoline - fueled engines and equipment. The installation receives gasoline, stores it in a underground storage tank, and dispenses it into motor vehicles and/ or nonroad engines. Therefore, the installation is subject to this rule. 7) 40 CFR Part 63, Subpart HHHHHH - National Emission Standards for Hazardous Air Pollutants: Paint Stripping and Miscellaneous Surface Coating Operations at Area Sources This rule applies to any area sources that engage in any of the following: • Paint stripping operations that use methylene chloride (MeC1)-containing paint stripping formulations; • Spray application of coatings to motor vehicles and mobile equipment; and a Spray application of coatings to a plastic and/or metal substrate where the coatings contain compounds of chromium (Cr), lead (Ph), manganese (Mn), nickel (Ni), or cadmium (Cd). The Lemay WWTP does not use methylene chloride (MeC1) for paint stripping. None of the materials that MSD uses contain the target HAP. MSD painters use brushes, rollers, and non - refillable aerosol cans (i.e., spray cans) in the booths. MSD does not perform spray applications of coatings to motor vehicles or mobile equipment at the Lemay WWTP. When spray applications are performed at the Lemay WWTP, they are for the purpose of facility maintenance. Spray coating applications defined as facility maintenance in 40 CFR §63.11180 are not subject to this rule. The materials that MSD uses in these spray applications are epoxies, urethanes, and paint materials that do not contain the target HAP. Spray applications have not historically been performed in the booths. Therefore, the installation is not subject to 40 CFR Part 63, Subpart HHHHHH. MSD - Lemav Wastewater "treatment Plant Part 70 Operating Permit SB - 9 Installation ID: 189-0217 Project No. 2005-06-025 8) 40 CFR Part 63, Subpart JJJJJJ - National Emission Standards for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers - Area Sources This regulation applies to boilers at area source facilities that burn coal, oil, biomass, or non -waste materials. Boilers burning natural gas as defined in this regulation would not be affected by the rule. This regulation does not apply to the boilers because the boilers are natural gas fired boilers. The rule exempts natural gas fired boilers with fuel oil as back-up fuel. According to this rule, gas -fired boiler includes any boiler that burns gaseous fuels not combined with any solid fuels, bums liquid fuel only during periods of gas curtailment, gas supply emergencies, or periodic testing on liquid fuel. Periodic testing of liquid fuel shall not exceed a combined total of 48 hours during any calendar year. National Enalss cn Standards for IHiazardous Air Pollutants (NESHAP) Appl$czbillty National Emission Standards for Hazardous Air Pollutants (NESHAPS) are stationary source standards for hazardous air pollutants. NESHAPS were originally required by the 1970 Clean Air Act (CAA). These standards were developed for sources and source categories that were determined to pose adverse risk to human health by the emission of HAPs. The Part 61 NESHAPs regulate only 7 hazardous air pollutants - Asbestos, Beryllium, Mercury, Vinyl Chloride, Benzene, Arsenic, Radon/Radionuclides. Prior to 1990, the Clean Air Act required EPA to set standards for each toxic air pollutant individually, based on its particular health risks. Thus, NESHAPs are risk based standards that apply to all existing and new/ modified sources regardless if they are a minor or major HAP Facility. (NOTE: This is not an analysis of every NESHAP standard; it is an analysis of the NESHAP standard that is potentially applicable to the installation). 1) 40 CFR Part 61, Subpart C - National Emission Standard for Beryllium The provisions of this subpart apply to extraction plants, ceramic plants, foundries, incinerators, and propellant plants which process beryllium ore, beryllium, beryllium oxide, beryllium alloys, or beryllium -containing waste; and machine shops which process beryllium, beryllium oxides, or any alloy when such alloy contains more than 5 percent beryllium by weight. The permittee has three incinerators which burn beryllium containing sewage sludge, therefore the incinerators are subject to the NESHAP standard for beryllium. 2) 40 CFR Part 61, Subpart E - National Emission Standard for Mercury. The provisions of this subpart are applicable to those stationary sources which process mercury ore to recover mercury, use mercury chlor-alkali cells to produce chlorine gas and alkali metal hydroxide, and incinerate or dry wastewater treatment plant sludge. The permittee has three incinerators which burn dry wastewater treatment plant sludge, therefore the incinerators are subject to the NESHAP standard for mercury. Permit Condition EP1-004 specifies a more stringent mercury limit of 0.28 mg per dry standard cubic meter pursuant to NSPS Subpart MMMM (Table 3). Complying with the more stringent requirement of Permit Condition EP1-004 would also be in compliance with 40 CFR Part 61, Subpart E, therefore 40 CFR Part 61, Subpart E is not included in this permit. 3) 40 CFR Part 61 Subpart M — National Emission Standard for Asbestos. The installation is not subject to any NESHAP standard with the exception of Subpart M - National Emission Standard for Asbestos. The installation is potentially subject to Subpart M. If the MSD - Lemay Wastewater Treatment Plant Part "7u Operating Permit SB - 10 Installation ID: 189-0217 Project No. 2005-06-025 installation conducts any demolition or renovation projects to a buildings) containing asbestos, they must determine applicability with the following NESHAP regulations: • Demolition and Renovation - 40 CFR 61.145 • Waste Disposal for Manufacturing, Fabricating, Demolition, Renovation, and Spraying - 40 CFR 61.150 Compliance Assurance Monitoring (CAM) Applicability 40 CFR Part 64, Compliance Assurance Monitoring (CAM) The CAM rule applies to each pollutant specific emission unit that: • Is subject to an emission limitation or standard, and • Uses a control device to achieve compliance, and • Has pre -control emissions that exceed or are equivalent to the major source threshold. The Incinerators are the only emission units that have pre -control PM emissions above the major source threshold. Since these units are subject to 40 CFR Part 60, Subpart MMMM standards and units that are subject to 111 or 112 standards promulgated after 11/15/90 are excluded from CAM, therefore the incinerators are not subject to CAM. Greenhouse Gas Emissions Potential emissions of greenhouse gases (CO2e) for this installation are calculated to be 15,604.46 tons, classifying the installation as a minor source of GHGs. There are no currently issued GHG regulations applicable to this installation. Missouri regulations do not require the installation to report CO2e emissions in their Missouri Emissions Inventory Questionnaire; therefore, the installation's CO2e emissions were not included within this permit. Other Regulatory Determinations 1) Incinerator #4 is taken out of service before the compliance date of 40 CFR Part 60 Subpart MMMM, Emission Guidelines and Compliance Times for Existing Sewage Sludge Incineration Units. 2) 10 CSR 10-6.220, Restriction of Emission of Visible Air Contaminants This rule applies to all particulate emitting sources listed in the emission units with limitations except the generators and emission units listed in emission units without limitations, i.e., equipment that does not have unit specific limitations at the time of permit issuance. At the time of issuance of this permit, the installation had already completed its weekly and bi- weekly observations, as required by the initial operating permit OP2000-108 conditions. The installation is currently conducting monthly observations as required by the previously mentioned permit condition. The installation had performed the initial weekly/biweekly observations and has been performing monthly monitoring; therefore it will be required to continue visible emissions observation on a monthly basis unless a violation occurs. If a violation occurs, the monitoring frequency will revert to a weekly schedule. This tiered monitoring frequency of visible/no visible emissions observations using Method 22 like procedures is considered sufficient. MSD - Lemay Wastewater Treatment Plant Part 70 Operating Permit Installation ID: 189-0217 SB-11 Project No. 2005-06-025 3) 10 CSR 10-6.400, Restriction of Emission of Particulate Matter From Industrial Processes 10 CSR 10-6.400 limits the amount of particulate matter that is allowed from an emission unit, and is dependent on the process weight rate of the material processed. The emission units to which this rule applies are listed below. The following calculations provide the allowable particulate emission rate based on 10 CSR 10-6.400 and the potential (maximum) emission rate including particulate emission control equipment. Potentials to emit presented below were calculated based on sources Maximum Design Rate (MDR). If the emissions from these emission units can not violate the limits of this rule then evidence of this is demonstrated in the following calculations. One of the following equations from 10 CSR 10-6.400 is used to calculate the PM allowable limit: E = 4.10P°'67 for process weight rates up to 30 tons (60,000 lbs) per hour, and E = 55.OP°'11— 40 for process weight rates greater than 30 tons (60,000 lbs) per hour Where: E = rate of emission in lb/hr; and P = process weight rate in tons/hr (maximum hourly design rate) a) EPO4 — Wet Ash Conveying with Venturi/Impingement Scrubber Process Weight rate (P) = 4.16 ton/hr Baghouse Efficiency = 94% Emission Limit (lb/hr) = 4.1 P°.67 = 4.1 x 4.160 = 10.66 lb PM/hr Emission Factor (controlled) = 4.80E-01 lb.rton (2014 EIQ)(Fire - SCC 30500717) PM Emission Controlled (lb/hr) = 0.48 lb x 4.16 ton = 2 00 lb ton hr hr This emission unit uses the same stack as the incinerators. Since the incinerators' PM emissions are continuously monitored, no monitoring, record keeping or reporting is required for this emission unit. b) EP 12 - Sand Blaster with Dust Collector Process Weight Rate (P) = 1.4 lb solid/min [1.4 lb/min x 60 min/hr x l ton/2000 lb] = 0.042 ton/hr Recycle Efficiency = 90% Control Efficiency = 99.2% Emission Limit (lb/hr) = 4.1P0•67 = 4.1 x 0.042'67 0.49 lb PM/hr PM Emission Controlled (lb.ihr) = 0.042 t x (1— 0.9) x (1— 0.99) = 0.084 lb hr The particulate matter potential emissions from the operation of the sand blaster is 0.084 lb/hr. Since this unit potentially emit less than one-half (0.5) pounds of particulate matter per hour it is exempt from the requirements of this rule. [10 CSR 10-6.400(1)(B)12.]. c) Because 10 CSR 10-6.070 (ASPS, Subpart MMMM) applies to the incinerators (EP1), 10 CSR 10-6.400 does not apply to the incinerators (EP1). d) The two paint spray booths (EP10) are equipped with control systems with particulate matter control efficiencies of 99%. According to 10 CSR 10-6.400(1)(B)14, the provisions of 10 CSR MSD - Lemay Wastewater Treatment Plant Part 70 Operating Permit SB - 12 Installation ID: 189-0217 Project No. 2005-06-025 10-6.400 shall not apply to coating operations equipped with a control system designed to control at least ninety-five percent (95%) of the particulate overspray. 4) 10 CSR 10-5.080, Incinerators. a) This regulation was rescinded on December 9, 1991 but it remains in the State Implementation Plan. Though the installation is subject to the requirements of this rule, it is not included in the operating permit because the particulate matter standard of this rule, 0.3 grains of particulate matter per standard cubic feet of exhaust gas is less stringent than the NSPS Subpart MMMM standards of 80 milligrams of particulate matter per cubic meter (0.03 grains per cubic meter). Compliance with the construction permit and the NSPS Subpart MMMM will ensure compliance with this rule. b) In the permit application, the burning of natural gas in the incinerator afterburners was presented as an alternate operating scenario; however, according to the DNR's Operating Permit Application Instructions, based on the EPA definition of "alternate operating scenarios", they are only needed if different modes of operation would change the method of documenting compliance. Since there would be no changes in the method of demonstrating compliance for these emission units due to the above scenario, it is not listed under Reasonably Anticipated Operating Scenarios. Also, the installation will not need to notify the St. Louis County Department of Health (SLCDOH) when the afterburners' fuel is changed to pipeline natural gas. Other Regulations Not Cited in the Operating Permit or the Above Statement of Basis Any regulation which is not specifically listed in either the Operating Permit or in the above Statement of Basis does not appear, based on this review, to be an applicable requirement for this installation for one or more of the following reasons: 1. The specific pollutant regulated by that rule is not emitted by the installation; 2. The installation is not in the source category regulated by that rule; 3. The installation is not in the county or specific area that is regulated under the authority of that rule; 4. The installation does not contain the type of emission unit which is regulated by that rule; or 5. The rule is only for administrative purposes. Should a later determination conclude that the installation is subject to one or more of the regulations cited in this Statement of Basis or other regulations which were not cited, the installation shall determine and demonstrate, to the APCP's satisfaction, the installation's compliance with that regulation(s). If the installation is not in compliance with a regulation which was not previously cited, the installation shall submit to the APCP a schedule for achieving compliance for that regulation(s).
