11 Introduction The Wisconsin Air Monitoring Network Plan is an annual report required under the 40 CFR 58 § 58.10(a)(1). e required to submit an annual network plan of State and Local Beginning July 1, 2007, state and local agencies ar ( SLAMS ), National Core Monitoring Network ( NCore ), Speciation Trends Network (STN ) Air Monitoring Stations Chemical Speciation Network (CSN) sites, Special Purpose Monitoring (SPM) sites and Photochemical sites, Assessment Monitoring Stations ( PAMS ) sites, if they exist. The plan must include a statement of the purposes for each monitor and evidence that siting and operation of each monitor meets the requirements of 40 CFR Part 58 Appendice s A, C, D, and E. In addition, the plan is due annually by July 1 and must be made available to the public for at least 30 days prior to its submission to EPA. Any modifications outlined in the plan are subject to approval of the EPA Regional Administrator, who shall approve or disapprove the plan within 120 days of submission. The goals of this plan are to provide evidence that the DNR air monitoring network meets current federal monitoring requirements, to detail any changes proposed for the 18 months f ollowing publication, to provide specific information on each of the DNR's existing and proposed monitoring sites, and to provide the opportunity for the public to comment on air monitoring activities conducted by the DNR. The plan also includes informatio n on known industrial monitoring activities and information on air toxics monitoring in the state. The DNR's air quality data are used to determine compliance with National Ambient Air Quality Standards (NAAQS). In 1970, the CAA established NAAQS for six pollutants known to cause harm to human health and the environment. The CAA requires the DNR to monitor these pollutants, called criteria pollutants, and report the to the EPA. The criteria pollutants are particulate matter, lead (Pb), ozone (O data ), nit ), sulfur rogen dioxide (NO 2 3 dioxide (SO ), and carbon monoxide (CO). The DNR monitors criteria pollutants to meet federal requirements. 2 The DNR, also, monitors for other pollutants such as air toxics and mercury. These pollutants do not have federal standards. Network Overview along with tribal and industrial partners in the DNR Primary Quality Assurance Organization (PQA O) The DNR operate 38 fixed sites throughout Wisconsin. One or more criteria pollutants are measured at 37 of these sites (the Brul e River site only includes monitoring for the National Atmospheric Deposition Program (NADP)) . The criteria monitoring sites include 3 S, two SPM sites, two tribal sites , and one industrial site . Monitoring sites 2 SLAM may have more purposes associated with them beyond the criteria pollutants network. Table 2 and Figure 1 show the sites run by DNR and DNR’s PQAO partners and the networks in which they are included. Table 3 shows the parameters that are monitored at each site. Bio Watch samplers operated at several sites in southeastern Wisconsin and industrial monitoring to satisfy state permit conditions are not included in these references.

The minimum monitoring requirements are codified in Appendix D of 40 CFR Part Wisconsin Department of Natural Resources 9 2020 Annual Air Monitoring Network Plan • June 201 7

18 58. Minimum monitoring requirements are specific to each indiv idual criteria pollutant (e.g. ozone, PM2.5) or objective based (e.g. NCore, NATTS ). Minimum monitoring requirements typically rely on population and/or air pollution emissions data. Wisconsin currently meets all minimum air monitoring requirements. Appendices A and B provide a detailed discussion of these requirements and any applicable waivers. Monitoring Objectives Since it is not possible to monitor everywhere in the state, monitoring sites are established according to T he concept of spatial scales is used to clarify the link federal rule to maximize spatial coverage. between monitoring objectives and the physical location of the monitor. When designing an air monitoring network one or more of the following six objectives should be determined: 1. Highest concentrations expected to occur in the area covered by the network 2. Representative concentrations in areas of high population density 3. Impact of specific sources on ambient pollutant concentrations 4. General background concentration levels 5. Extent of regional transport among populated areas and in support of secondary standards 6. Welfare -related impacts in the more rural and remote areas Site Selection The selection of air monitoring sites is usually based on at least one of these basic monitoring objectives: • Determine representative concentrations and exposure in areas of high population density • Determine the highest concentrations of pollutants in an area based on topography and/or wind patterns • Judge compliance with and/or progress made towards meeting the N AAQS • Track pollution trends • Determine the highest concentrations of pollutants within the state based on the known atmospheric chemistry of specific pollutants and wind patterns • Determine the extent of regional pollutant transport to and from populated are as • Determine how much major sources impact ambient pollution levels • Validate control strategies designed to prevent or alleviate air pollution • Provide a database for research and evaluation of air pollution effects • Determine general background concentration levels The exact location of a site is often dependent on the logistics of the area chosen for monitoring, such as considerations of federal siting criteria, access, security and power availability. DRAFT Network Scales The EPA developed a system which spec ifies an exclusive area or spatial scale that an air monitor represents. The goal in establishing air monitoring sites is to correctly match the spatial scale that is easurement most appropriate for the monitoring objective of the site (Table 5). The representative m scales are: Defines the concentrations in air volumes associated with area • Micro scale (10 -100 m) – Wisconsin Department of Natural Resources 9 2020 Annual Air Monitoring Network Plan • June 201 8

19 dimensions ranging from several meters up to about 100 meters. Measurements on the micro scale typically include concentrations in street canyons , intersections and areas next to major emission sources. • Middle Scale (100 – Defines the concentration typical of areas up to several city blocks -1,000 m) in size with dimensions ranging from about 100 to 1,000 meters. Neighborhood Scale ( 0.5 -4 km) – Defines concentrations within some extended area of the city • to four kilometers that has relatively uniform land use with dimensions in the half kilometer range. Generally, these stations represent areas with moderate to high population densities. • Urban Scale (4 -50 km) – Defines the overall, citywide conditions with dimensions on the order of four to 50 kilometers. This scale represents conditions over an entire metropolitan area and is useful in assessing city -wide trends in air quality. • Regional Scale – Usually a rural area of reasonably homogeneous geography without large sources and extends from tens to hundreds of kilometers. • National and global scales —These measurement scales represent concentrations characterizing the nation and the globe as a whole.

Under the direction of the Lake Michigan Air Directors Consortium (LADCO), DNR collaborated with other states in our region for the first network assessment which was completed in 2010 . The network assessment provides a detailed evaluation of the regional air -evaluation of the types of pollutants monitored monitoring network. It contains a network history, a re and an evaluation of the network's objectives and costs. Also, it includes spatial analysis of ambient air monitoring data and a reconsideration of monitor placement based on changes in land use and population. For the 2015 Network Assessment, DNR again collaborated with other EP A Region 5 states. The results DRAFT of the 2015 Regional Network Assessment can be found on LADCO’s website at . -reports/ https://www.ladco.org/reports/monitoring Recommendations of the 2015 Network Assessment • Criteria pollutant monitoring networks are adequat e to meet EPA’s minimum monitoring criteria. • Monitoring equipment is aging and will require replacement in the coming years. ) which has an aerodynamic • Disinvestment or relocation of existing five particulate matter (PM 2.5 9 Wisconsin Department of Natural Resources 2020 Annual Air Monitoring Network Plan • June 201 9

20 diameter ozone monitoring sites is very difficult due to stringent EPA and less than 2.5 microns criteria for shutdown. • Regionally coordinated field studies would be helpful to better understand the impacts of ozone along the lakeshore. Studies could prov ide data that may be precursors on ozone concentrations used to update and improve the regulatory meteorological and photochemical models that are used to estimate future ozone values . Quality Assurance/Quality Control (QA/QC) Program The purpose of the QA/QC program is to assure the quality of data obtained from the DNR air monitoring sites. The DNR meets or exceeds the QA requirements defined in 40 CFR 58 and all applicable appendices. The QA/QC program includes but is not limited to the following activities: • Instrument performance audits • Monitor siting evaluations • Zero, precision and span checks • Bias determinations • Flow rate audits Leak checks • • Data validation For independent quality assurance activities, the DNR participates in EPA's National Performance Audit Performance Evaluation Program (NPAP) which includes Through the Probe (TTP) audits, the PM 2.5 PEP for criteria pollutant monitoring. Additional inter- laboratory Program (PEP) program and the Pb comparisons of performance test and exchange samples are performed periodically for air toxics monitoring. PQAO As the for three partner organizations in Wisconsin, the DNR operates under an EPA approved Quality Management Plan (QMP) and utilizes Quality Assurance Project Plans (QAPPs) for each statewide monitoring network. The prima ry purpose of the QAPPs is to provide an overview of the project, describe the need for the measurements, and define QA/QC activities to be applied to the s must project. All other ambient air monitoring initiatives including state, tribal, and industrial project have a DNR approved monitoring plan for each specific project. As part of instrument performance audits, each monitoring site is assessed to ensure that all applicable assure a safe work EPA siting requirements are fully met. This also includes a safety inspection to environment for site operators and staff and that monitoring stations are being properly maintained. DRAFT Data Processing and Reporting With the exception of the CSN , mercury (Hg), NADP and BioWatch data; ambient air quality data are in a centralized server housed at the Wisconsin Department of Administration. stored Continuous pollutant monitoring data are retrieved hourly and posted to the DNR Air Quality website (https://airqua lity.wi.gov/StateMapping.aspx ) and sent to EPA’s AirNow web site AQS ( https://gispub.epa.gov/airnow/ ).

BioW atch data is processed and reviewed by the national program and housed within their internal systems. Criteria Pollutants Network The DNR monitors the six criteria pollutants established by the 1970 CAA to show compliance with the NAAQS. The criteria pollutants network serves many additional purposes including public reporting of air quality, determining pollution trends, monitoring specific emissions sources, investigating background conditions and evaluating computer models. The criteria pollutants are particulates ( PM and PM ), 2.5 10 , NO , SO , and CO. The DNR works with adjacent states to meet the criteria pollutant Pb, O 2 3 2 requirements. These cooperative efforts are described in the Memorandums of Agreement (MOAs) fou nd in Appendix C. The EPA has developed primary and secondary NAAQS for each of the criteria pollutants. Primary standards are set to protect public health, while secondary standards are set to protect the environment and public welfare (i.e. , visibility, crops, animals, vegetation, and buildings). The CAA requires the EPA to review the scientific basis of these standards every five years to ensure they are protective of public health and the environment. Table 6 , found on the EPA website at air- https://www.epa.gov/criteria- -table pollutants/naaqs , describes the NAAQS standards (as of February 2019).

23 Particulate Matter Particulate matter is not a single pollutant but rather a mixture of solid particles and liquid droplets distributed among numerous gases that interact with solid and liquid phases. The DNR monitors four , coarse particulate matter (PM ) which has an aerodynamic different particle fractions: PM 2.5 10- 2.5 particulate matter with an aerodynamic diameter less than 10 between diameter 2.5 to 10 microns, microns (PM ), and total suspended particulate matter (TSP) which includes the total mass of particles 10 found in a sample of ambient air.

The annual NAAQS for 3 3 3 PM to 12 μg/m was lowered from 15 μg/m . The PM 24- hour standard was retained at 35 μg/m . 2.5 2.5 3 The PM 24- hour standard was also retained at 150 μg/m . There are currently no air quality standards 10 . for PM 10- 2.5 Networks PM 2.5 There are currently 20 PM sites in Wisconsin including two tribal sites (Figure 2). Two types of 2.5 regulatory PM monitors operate in Wisconsin: filter based Federal Reference Method ( FRM ) 2.5 samplers, continuous based Federal Equivalent Method ( FEM ) analyzers. collect a 24 -hour mass sample of PM The FRM monitors on Teflon filters. FRM monitors are used to 2.5 meet collocation requirements for continuous methods in Wisconsin. They sample between one in every three days to one in every six days. Table 7 summarizes the current sampling frequencies for the FRM monitors. PM data collected using this method are used for quality assurance purposes and may be 2.5 substituted in for primary monitors and compared to the NAAQS to demonstrate compliance. FRM data is submitted to AQS. The con tinuous based FEM PM analyzers are a combination of Teledyne T640/T640X and Met One 2.5 Instruments ( BAM )- 1020 continuous monitors that collect and report hourly Beta Attenuation Monitors PM concentrations. All T640/T640X/BAM -1020 monitors operating in W isconsin are designated as 2.5 FEM and can be used to demonstrate compliance with the PM NAAQS. Hourly PM data are also used 2.5 2.5 to calculate the air quality index (AQI) and develop AQI forecasts for Wisconsin. Continuous data are reported to the DNR’s Air Q uality website ( https://airquality.wi.gov/StateMapping.aspx ) and the EPA’s https://gispub.epa.gov/airnow/ AIRNow website ( ) as well as AQS. The PM network includes 20 sites where continuous FEMs operate as primary samplers. The transition 2.5 with EPA in January 2019. Four sites continue to a primary FEM network was completed in collaboration to operate collocated FRMs for quality assurance purposes (Figure 2). DRAFT The PM FEM continuous network has several advantages over the FRM network. Continuous FEMs 2.5 sample on a daily basis while FRMs are intermittent samplers that typically run every three or six days. Continuous monitoring also allows for real time evaluation of data to assist in the identification of air quality episodes. Finally, continuous PM monitoring provides hourly data that assists in understanding 2.5 how concentrations vary throughout the day. If a PM monitoring site were discontinued due to circumstances beyond the DNR’s control, a 2.5 Wisconsin Department of Natural Resources 9 2020 Annual Air Monitoring Network Plan • June 201 13

24 replacement site would be established if the site exceeded the NAAQS or if it is the "design discontinued value site" for a required metropolitan statistical area (MSA). In this case, all possible efforts w ould be made to find a new site that is physically close to the discontinued site and has a similar scale and monitoring objective. However, if the discontinued site were not an exceeding or "design value site" for a replacement site is desired for NAAQS compliance or other a required MSA, the DNR would evaluate if purposes. A monitoring site meets the annual PM NAAQS if the three -year average of the annual average PM 2.5 2.5 3 concentration is less than or equal to 12 μg/m 2016 through 2018 . Figure 3 shows the average of the annual average PM concentrations at Wisconsin sites and compares them to the standard. Wisconsin 2.5 3 3 2 μg/m averages ranged from 4. in Bad River to 8.3 μg/m in Waukesha. Therefore, all sites were below the annual standard. A site meets PM the 24 -hour NAAQS if the 98th percentile of the 24 -hour PM concentrations in a 2.5 2.5 3 shows the average of 2016 .

PM Networ k 10 The DNR currently operates PM FRM monitors at two monitoring sites. This method collects mass 10 samples of PM over a 24 -hour period once every six days. 10 The DNR also operates continuous PM FEM monitors that measure hourly PM concentrations at fiv e 10 10 sites: Devils Lake, Horicon Wildlife Area, Madison University Milwaukee SER DNR Hdqrs and Waukesha. At these sites, a monitor measures PM and calculates concentrations in bot h local conditions (LC) and 10 ressure (STP). The LC at s temperature and p measurements are appropriate for calculating tandard coarse particulate concentrations but are not appropriate for comparison with the NAAQS. The STP measured values are used for comparison to the NAAQS. Figure 5 shows the locations of the PM monitors in Wisconsin in 2019. 10 Wisconsin currently meets applicable NAAQS for PM at sites with three years of complete data. A 10 3 monitoring site meets the 24 -hour PM is not exceeded more than NAAQS when the level of 150 μg/m 10 once per year on average over 3 years.

40 Non-Criteria Pollutant Networks (NCore) National Core Monitoring Network The NCore multi -pollutant sites are part of an overall strategy to integrate multiple monitoring networks and measurements. Each state (i.e. the fifty states, District of Columbia, Puerto Rico, and the Virgin Islands) and some local government entities are required to operate at least one NCore site. Monitors at NCore multi- po llutant sites measure particulates (PM , PM , speciated PM NOy , SO , CO, , and ), O 3 2 10- 2.5 2.5 2.5 basic meteorology. In addition, a number of urban NCore sites may be selected to measure lead (Pb). The objective is to locate sites in broadly representative urb an (about 63 sites) and rural (about 17 sites) locations throughout the country to help characterize regional and urban patterns of air pollution. In CSN many cases, monitoring organizations collocate these sites with sites measuring speciated PM 2.5 components, PAMS sites already measuring ozone precursors, and/or National Air Toxics Trends Station (NATTS ) sites measuring air toxics. By combining these monitoring programs at a single location, EPA pollutant information available. This greatly enhances the and its partners maximize the multi- foundation for future health studies, NAAQS revisions, validation of air quality models, assessment of emission reduction programs, and studies of ecosystem impacts of air pollution. Wisconsin’s NCore site (Horicon Wildlife Area) is located in Dodge County representing a rural area. High sensitivity NO began operating at Mayville located in Dodge County in 2005 and 2006 and , CO, and SO 2 y moved to Horicon in 2010. Near -Road Air Quality Monitoring In 2010, the EPA i ntroduced a new air monitoring network to measure air pollution levels near heavily trafficked roadways. Near- road air monitoring sites are required to be located within 50 meters of the busiest roadways across the country. Near -road monitoring sites are required to measure hourly levels of NO , CO and PM . Complete details about near-road monitoring can be found on the DNR’s web site 2.5 2 at http://dnr.wi.gov/topic/AirQuality/Monitor.html . On December 30, 2016, EPA finalized “The Revision ) Monitoring Requirements” which eliminated Phase 3 of to Near -Road Ambient Nitrogen Dioxide (NO 2 this requirement. Phase 3 would have required a second monitoring station in Madison. In Wisconsin, DNR installed one near -road monitoring site as required. It began operating along the Chicago/Kenosha/Milwaukee corridor near I -94 in Milwaukee on January 1, 2014. Various parameters are being measured at the near -road site (Table 8). ear -Road Parameters 8: N Table DRAFT FEM 2.5 2 CO NO PM Site Name City AQS Site ID Other Parameters Milwaukee - College Ave. N R 55 - 079 - 0056 Milwaukee x x x PM , PM , Meteorological - 2.5 10 10 The DNR near -road air quality monitoring is described in more detail on the DNR near- road website at http://dnr.wi.gov/topic/AirQuality/Monitor.html .

41 Air Toxics Air toxics include, but are not limited to, the 190 Hazardous Air Pollutants (HAPs) specified in the 1990 for a list of HAPs). In 1999, EPA CAA Amendments (see http://www.epa.gov/ttn/atw/orig189.html finalized the Urban Air Toxics Strategy (UATS). The UATS states that emissions data are needed to quantify the sources of air toxics impacts and aid in the development of control strategies, while ambient monitoring data are needed to understand the behavior and concentration of air toxics in the atmosphere after they are emitted. Part of this strategy included the development of the NATTS . The NATTS program measures core air toxics pollutants including VOCs, carbo nyls, metals, and program PAHs ). polycyclic aromatic hydrocarbons ( The DNR monitors metals, VOCs, carbonyls and PAHs at Horicon Wildlife Area (55 -027 -0001) which operates as a rural NATTS site on a one in six day schedule .

The toxics monitoring sites appear in Figure 1 samples collected by DNR are analyzed at the Wisconsin State Laboratory of Hygiene (WSLH). Specific data quality objectives are set for monitoring sites in the NATTS network. EPA has established a goal to be able to detect a 15% concentration change between two 3 -year annual mean concentrations within acceptable error at NATTS sites. The NATTS data are also used for: Tracking trends in ambient levels to evaluate progress toward emission and risk reduction goals • Evaluating public exposure & environmental impacts in the vicinity of monitors • • data for risk characterization Providing quality assured • Assessing the effectiveness of specific emission reduction activities • Evaluating and subsequently improving air toxics emission inventories and model performance Metals Metals are extracted from PM filters and analyzed us ing inductively coupled plasma mass 10 spectrometry (ICP -MS ) following an EPA method.

52 Appendix A : Minimum Monitoring Requirements and 201 9 Monitor Classifications Summary The EPA establishes the minimum number of monitoring sites required to meet national ambient monitoring objectives. The minimum monitoring requirements are codified in Appendix D of 40 CFR Part monitoring requirements are specific to each individual pollutant (e.g. ozone, PM ) or 58. Minimum 2.5 objective based (e.g. NCore, PAMs) monitoring network. Minimum monitoring requirements typically rely on population and/or air pollution emissions data. Wisconsin currently meets all minimum air monitoring requirement s. This appendix provides a detailed description of these requirements. It also e, provides tables that describe each monitor’s scale, objectiv hod , and collocation where required . met There are no t any Prevention of Significant Deterioration (PSD) monitors in Wisconsin. Federal Regulation 40 CFR § 58.10 (a)(1) Beginning July 1, 2007, the state, or where applicable local, agency shall submit to the Regional Administrator an annual monitoring network plan which shall provide for the documentation of the establishment and maintenance of an air quality surveillance system that consists of a network of SLAMS monitoring stations that can include FRM, FEM, and ARM monitors that are part of SLAMS, NCore, CSN, PAMS, and SPM stations. The plan shall include a statement of whether the operation of each monitor meets the requirements of appendices A, B, C, D, and E of this part, where applicable. The Regional Administrator may require additional information in support of this statement.

84 Appendix C: Memorandums of Agreement Summary Due to the geographic monitoring boundaries determined by EPA, Wisconsin is working collaboratively with adjacent states to meet 40 CFR 58 Appendix D, Section 2(e) minimum monitoring requirements. Memorandum of s) are designed to reaffirm that we are meeting monitoring requirements established by EPA. The Agreements (MOA two following MOAs constitute this reaffirmation. DNR reconfirmed with Minnesota Pollution Control Agency’s monitors are meeting minimum monitoring requirements. Due to the age of the MOA, an updated Minnesota -Wisconsin MOA will be developed to reflect current monitoring configurations. Federal Regulation 40 CFR § 58 Appendix D to Part 58 2(e) This appendix uses the statistical -based definitions for metropolitan areas provided by the Office of Management and Budget and the Census Bureau. These areas are referred to as -based statistical areas (CBSA), and metropolitan statistical areas (MSA), micropolitan statistical areas, core combined statistical areas (CSA). A CBSA associated with at least one urbanized area of 50,000 population or greater is termed a Metropolitan Statistical Area (MSA). A CBSA associated with at least one urbanized cluster of at least 10,000 population or greater is termed a Micropolitan Statistical Area. CSA consist of two or more adjacent CBSA. In this appendix, the term MSA is used to refer to a Metropolitan Statistical Area. By definition, both MS A and CSA have a high degree of integration; however, many such areas cross State or other political boundaries. MSA and CSA may also cross more than one air shed. The EPA recognizes that State or local agencies must consider MSA/CSA boundaries and their own political boundaries and geographical characteristics in designing their air monitoring networks. The EPA recognizes that there may be situations where the EPA Regional Administrator and the affected State or local agencies may need to augment or to div ide the overall MSA/CSA monitoring responsibilities and requirements among these various agencies to achieve an effective network design. Full monitoring requirements apply separately to each affected State or local agency in the absence of an agreement be tween the affected agencies and the EPA Regional Administrator. DRAFT

149 Appendix E : Enhanced Ozone Monitoring Plan Introduction 40 CFR Part 58 Appendix D 5(h) , DNR is providing an enhanced ozone monitoring As required by plan Appendix D (5)(h) states, in part : (EMP). The EMP will include monitoring activities deemed important to understanding the O problems in the 3 state. Such activities may include, but are not limited to, the following: (1) Additional O monitors beyond the minimally required under paragraph 4.1 of this appendix, 3 Additional NO (2) or NO monitors beyond those required under 4.3 of this appendix, y X (3) Additional speciated VOC measurements including data gathered during different periods other than required under paragraph 5(g) of this appendix, or locations other than those required under paragraph 5(a) of this appendix, and (4) Enhanced upper air measurements of meteorology or pollution concentrations. Overview EPA approved an enhanced ozone monitoring plan as part of its approval of Wisconsin’s 2019 ANP. As part of its continued commitment to enhanced ozone monitoring, DNR plans to: • Continue monitoring ozone concentrations at additional sites beyond those required. Continue monitoring ozone precursors • ( NO and VOCs ) at additional monitors beyond those x required. • Analyze data from the 2017 Lake Michigan Ozone Study (LMOS 2017) and consider the results of the study in future regulatory submittals and modeling. • Install upper air meteorology instrumentation Taken together, this continued enhanced monitoring and analysis of the results from LMOS 2017 DRAFT itional insights into the mechanisms and dynamics of ozone formation should provide significant add and help advance understanding of the and transport along Wisconsin’s Lake Michigan lakeshore ozone problems in the state. Monitoring of ozone and ozone precursors beyond those required DNR is conducting enhanced ozone monitoring at two sites located inland from the Lake Michigan

Enhanced monitoring of ozone precursors DNR currently monitors the concentrations of nitrogen oxides (NOx and VOCs ) at two locations: Milwaukee SER DNR Hdqrs (55 -079 -0026) and Manitowoc W oodlnd Dunes (55 -071 -0007).

161 SULFUR DIOXIDE DISPERSION MODELING ANALYSIS Sheboygan, Wisconsin Power and Light Edgewater Generating Station - Wisconsin February 2019 INTRODUCTION the United States Environmental Protection Agency (USEPA) issued the final Data On August 21, 2015 -hour Sulfur Dioxide (SO Requirements Rule for the 2010 1 ) National Ambient Air Quality Standard 2 DNR) identified (NAAQS). On January 15, 2016, the Wisconsin Department of Natural Resources (W -Edgewater) as requiring further air Wisconsin Power and Light’s Edgewater Generating Station (WPL quality characterization under the rule. In January 13, 2017, WDNR characterized the ambient SO 2 concentrations around WPL -Edgewater using air quality dispersion modeling. According to §51.1205(c), the ongoing data requirements of the Data Requirement Rule, if WDNR demonstrates that the area would meet the 2010 SO NAAQS with allowable emissions, then future 2 ot required. The analysis used the regulatory dispersion model annual reports for the area are n AERMOD (AMS/EPA Regulatory Model) following the methods outlined and the input parameters listed. AREA CHARACTERIZATION WPL, a utility subsidiary of Alliant Energy Corporation, operates the Ed gewater Generating Station which is located in the southern part of the City of Sheboygan, adjacent to Lake Michigan in Sheboygan - County, Wisconsin. Sheboygan is located in east central Wisconsin approximately 50 kilometers north northeast of Milwaukee. The climate of Sheboygan is characterized by variable weather patterns with a large seasonal temperature range and moderate amounts of precipitation. Temperature extremes are ameliorated by proximity to Lake Michigan, with its attendant lake and land breeze circulations. The terrain in Sheboygan County is generally flat, except in the western portion of the county (approximately 30 kilometers west of the City of Sheboygan) where local relief is 500’ -600’ above the elevation of Lake Michigan. MODEL & METEOROLOGY WDNR used the current regulatory version (18081) of AERMOD in the dispersion modeling analysis, with -Edgewater consists primarily of water (Lake the regulatory default options. The area around WPL Michigan), commercial property, residences, and the Sheboygan Wastewater Treatment Plant. Guideline on Air Quality Models (40 CFR Part 51, Appendix W, USEPA, January 2017) Following the , an DRAFT assessment of the land use around WPL -Edgewater shows that less than 50% of the land area within 3 kilometers is industrial, commercial, or dense residential. Therefore, rural dispersion coefficients were used in AERMOD. Meteorological data was processed from 2011 -2015 Sheboygan County Memorial Airport (KSBM) surface data with Green Bay upper air data. The meteorological data was processed with the regulatory RMET (16216) and is the publicly available options (including the adjusted friction velocity ADJ_U*) in AE 9 June 201 Annual Air Monitoring Network Plan • Wisconsin Department of Natural Resources 2020 G-3

This minute AERMINUTE (15272). P rocessing used an anemometer height of 10.0 meters above ground. On April 25, 2018, USEPA released AERMET (18081) but the code corrections and change to user input methods have no effect on the surface or profile files. The instrumentation tower at KSBM is 13 kilometers northwest of WPL -Edgewater and is the closest station that records wind speed and direction each minute. The data collected is considered representative of meteorological conditions around the facility. The Sheboygan County Memorial Airpo rt is west of the City of Sheboygan and is surrounded by small farm fields and wetlands. The climate of the area is dominated by the lake breeze circulation developed by Lake Michigan, and with no -Edgewater and the airpo geographic features in between WPL rt, the wind patterns will be similar between the sites. Surface characteristics around KSBM were generated using AERSURFACE (13016) following the methods AERMOD Implementation Guide. described in the Specifically, snow cover for each month during the period 2011 -2015 was derived from National Snow Analyses maps from the National Operational -snow conditions. The Hydrologic Remote Sensing Center. AERSURFACE was run both for snow and no albedo, Bowen ratio, and surface roughness were adjusted based on the number of days with snow cover during each month. Also as detailed in the , soil moisture AERMOD Implementation Guide conditions for each meteorological data year were based on the monthly Palmer Drought Severity Index for the area as obtained from the National Centers for Environmental Information. RECEPTOR GRID The receptor grid (61798 points) used in the analysis consists of a series of nested rectangular grids with terrain derived from AERMAP using National Elevation Dataset information: 25 meter spacing to 500 meters from the sources   50 meter spacing to 4 kilometers from the sources  100 meter spacing to 10 kilometers Receptors located inside the fence line of WPL -Edgewater, or are otherwise not considered ambient air, were removed from the modeling analysis. EMISSIONS INVENTORY WPL -Edgewater is a base load electrical generating facility with nominal capacity of 380 megawatts that began operation during the 1930’s. The facility consists of one pulverized subbituminous coal fired boiler/generator set, with maximum rated heat capacity of 4,366 million British Thermal Units per hour (MMBtu/hr) labeled Unit 5. Unit 5 is limited to 0.075 lbs/MMBtu of SO -day rolling average by over a 30 2 -R1.

The facility digests municipal liquid waste and combusts the gas in micro -turbines to produce small amounts of electricity. The Sheboygan WWTP currently has coverage under the Wiscons in Type B Registration Permit. As part of the permit application, Sheboygan WWTP provided maximum hourly SO emission rates for all sources at the facility. The maximum impact of Sheboygan 2 9 June 201 Annual Air Monitoring Network Plan • Wisconsin Department of Natural Resources 2020 G-4

163 WPL WWTP will not occur in the same location as the maximum impact of -Edgewater, but will be in the vicinity of WPL -Edgewater itself; therefore, the emissions are included in this analysis. INPUT PARAMETERS Modeled stack parameters and building downwash data for WPL -Edgewater were taken from the most recent WDNR analys is for the facility, with additional information provided by WPL. Modeled emission rates for Unit 5 (S12) reflect both the highest potential short-term hourly rate corresponding to the - maximum heat input. The representative exhaust gas flow rate and temperature were used. BPIP PRIME was also used to produce the building downwash information from facility provided plot plans. The federally enforceable emission limit for WPL -Edgewater Unit 5 (S12) as of January 1, 2017 is based -day average of 0.0 75 lbs/MMBtu. WPL conservatively estimates that the potential hourly on the 30 -term limitation. The WPL -day emissions limit of 0.075 -Edgewater S12 30 emission rate is twice the long lbs/MMBtu was multiplied by two resulting in a maximum hourly emission rate estimate of 0.150 lbs/MMBtu. This value was then used to calculate a representative, conservative estimate of potential hourly emissions from WPL -Edgewater S12 based on boiler heat input. - SHEBOYGAN WPL EDGEWATER s Point Source Stack Parameters & Emission Rate Rate DIAM TEMP SO HEIGHT LOCATION HEIGHT VELOCITY 2 ID (#/HR) (M) (K) (M) (UTM83) (ft) (M/S) S12 443063, 4840702 167.03 548.0 5.486 33.57 348.4 655.0 Sheboygan WWTP S01 443014, 4840809 4.420 14.5 0.9601 20.00 1273.0 1.27 0.5090 S02* 442921, 4840786 8.230 27.0 4.337 394.3 0.336 * 2.363 442929, 4840825 0.160 422.0 S03A 0.3566 9.632 31.6 * S03B 442929, 4840823 9.632 31.6 2.363 422.0 0.160 0.3566 S04A 442932, 4840836 4.877 16.0 0.3048 21.11 533.2 0.130 16.0 S04B 442934, 4840836 4.877 21.11 0.3048 533.2 0.130 S05A 4.877 16.0 0.3048 442917, 4840836 24.62 533.2 0.120 442925, 4840836 4.877 16.0 0.3048 24.62 533.2 0.120 S05B 0.9144 0.060 388.7 2.278 S06 442850, 4840911 8.230 27.0 *Obstructed stacks modeled as POINTCAP source type Modeled stack parameters and maximum hourly emission rates for Sheboygan WWTP were taken from permit applications from the facility.

When calculating the hour of day and season values, the selected value Ambient Air Quality Standard should represent the ranked percentile of the standard. However, the March 2011 Clarification memo also discusses calculating concentrations by hour of day and month, but using a higher ranked value -2015 hour of day and month such as the maximum in each period. Using the maximum average 2013 th concentration is more conservative than using the 99 percentile values. In additio n, using hour of day and month values addresses questions about the seasonal definition of winter months in AERMOD. MODELING RESULTS -hour SO NAAQS is calculated with all other -Edgewater in relation to the 2010 1 The impact of WPL 2 sources operating. The regulatory option in AERMOD was selected and results compiled consistent with -hour, plus the form of the 1 -hr NAAQS, i.e. the five -year average of the fourth highest daily max background, was computed for each receptor and compared with the standard. The result from the analysis shows concentrations below the NAAQS for the worst -case, and thus for all, operating scenarios. The maximum impact of all sources is near Sheboygan WWTP but WPL -Edgewater -Edgewater is located 3.2 does not contribute to this modeled value. The maximum impact of WPL kilometers northwest of the facility in a commercial area. Results are presented both in micrograms per 3 o cubic meter μg/m ( ) and in parts per billion (ppb), assuming a conversion factor (1 atm, 20 C) of 1 ppb = 3 2.616 μg /m .

WPL -Edgewater and the Sheboygan WWTP were modeled with 2 emissions following the procedur es in the Guideline on Air Quality Models (40 CFR Part allowable SO 2 Wisconsin Modeling Guidelines (March 2018) and the .

165 emissions in the county, as well as distant emissions, were appropriately smaller sources of SO 2 consider ed in the background concentration. This analysis therefore supports that, under the SO Data 2 Requirements Rule, future annual reports for the Sheboygan County, Wisconsin area will not be required.
