Introduction

The U.S. Environmental Protection Agen cy (EPA) revised the primary National Ambient Air Quality Standard (NAA QS) for sulfur dioxide (SO 2 ) on June 2, 2010. To better protect public health, th e EPA replaced the 24-hour and annual SO 2 standards, set in 1971, with a new shor t-term standard based on the 3-year average of the 99 th percentile of the yearly dist ribution of 1-hour daily maximum concentration. The new level was set at 75 parts per billion (ppb).

In accordance with Section 107 of the federal Clean Air Act (CAA), within one year of a new or revised NAAQS, states are to s ubmit designation recommendations to the EPA. The recommendations should include the boundaries for areas to be designated as nonattainment. The EPA issued a guidance memorandum on March 24, 2011, to direct states on the SO 2 designation process and time line. The me mo also contains a description of the five factors that the EPA will use to evaluate the states’ recommendations, as well as an explanation of the expected use of modeling to support the recommendations.

The analysis and recommendations for the SO 2 designation recommendations for the State of Michigan have been develo ped by the Michigan Department of Environmental Quality (MDEQ), Air Quality Division, in conjunction with partners and stakeholders of the Southeast Michi gan Ozone Study committee (SEMOS). The excellent contributions of the m any technical experts from academia, industry, commerce, and nongovernmental organizations have been invaluable in this endeavor.

Regulatory History in Michigan

Michigan established emissions limitati ons and prohibitions for sulfur-bearing compounds for fuel burning equipment in 1976 (Rule 49) under 1965 PA 348, the Air Pollution Act, now established in Part 55, Air Pollution Cont rol, of the Natural Resources and Environmental Protec tion Act, 1994 PA 451, as amended (Part 4 rules). Wayne County operated a local ai r pollution program for a time. The county also adopted sulfur-in-fuel regulat ions applicable to sources within its jurisdiction. The Wayne County sulfur limitations have been in corporated into the state’s Part 4 rules, and these rules wil l be in the Michigan State Implementation Plan (SIP), once approved by the EPA. Michi gan’s Part 4 rules also limit sulfur emissions from oil and gas producing, transporting, or pr ocessing and from sulfuric acid and sulfur recovery plants.Page 2 Federal programs have also provided for SO 2 reductions both regionally and nationwide, including the federal motor vehicle and motor vehicle fuel control program under Title II of the CAA, t he New Source Performance Standards under Section 111, the Acid Rain Program under Title IV, and the Clean Air Interstate Rule, which applies to the eastern half of the U.S.

Nonattainment Area

The MDEQ recommends a nonattainment area based on a weight of evidence (WOE) demonstration that takes into c onsideration air quality data, emissions data, meteorological data, and major SO 2 source locations in Wayne County. The recommended nonattainment area is shown in Figure 1. The nonattainment area is bound by the Canadi an border on the east to the Wayne County border on the south end, follows Interstate 75 on the west side to Southfield Road (M39) to Interstate 94 East (Detroit Industria l Expressway) to Michigan Avenue (US12) on the northern boundary. Since the MDEQ has not completed their SO 2 modeling for all SO 2 sources in the state, t he MDEQ is recommending the remaining counties and portion of Wa yne County in Michigan be designated unclassified. The basis for this WOE nonattainment recommendation is discussed in the following sections of this document.

Figure 1. Recommended Nonattainm ent Area for Wayne County, MI.

Zug IslandPage 3 Air Quality Data

The MDEQ currently operates three SO 2 monitors in Michigan. Two monitors are located in Wayne County, and one is locate d in Kent County. The Kent County monitor and one of the Wayne County moni tors show attainment with the SO 2 NAAQS.

The two Wayne County monitors are loca ted at Allen Park and Southwestern High School (SWHS). Figure 2 shows the location of these monitors.

Based on 2008-2010 data, the Allen Park m onitor is showing attainment with the new 1-hour SO 2 NAAQS (75 ppb), with a 3-year average 4 th highest daily maximum hourly value of 56 ppb. In contrast, the 3-year average 4 th highest values at the SWHS monitor shows nonattainment at 96 ppb. Wayne County had two additional monitors that were s hut down in 2007 due to funding issues. Values at these monitors were decr easing in 2006 and 2007. In 2007 these monitors recorded 1-hour values that w ould have shown attainment for the 2010 SO 2 NAAQS (See Table 1).

Figure 3 shows the graphical dep iction of the values in Table 1, the annual 99 th percentile of the daily maximum 1-hour values for the curr ent and historical monitors in Wayne County from 2 004-2010. The most recent annual 99 th percentiles of the 1-hour va lues are all below the SO 2 NAAQS except at the SWHS site.

For the most recent three years, Allen Park is 30 to 50 ppb less than SWHS. These monitors are approximately sev en miles apart. The Linwood monitor, which was removed in 2007, is less than four miles northeast of the SWHS monitor. When the Linwood monitor wa s operating, it was over the 2010 SO 2 NAAQS standard in 2004-2006 but showed attainment of the standard for 2005- 2007. Given the significant SO 2 reductions that have occurred since the Linwood monitor was shut down (low-sulfur gasoline rule, ultra-low sulfur diesel rule, and CAIR) and the fact that historically its SO 2 concentrations were 30 to 50 ppb less than those measured at SWHS, we fully ex pect that this moni tor would likely still show attainment in 2008-2010.Page 5 Figure 3. Annual average 99 th percentile for SO 2 monitoring data in Wayne County.

This difference in the concentrations between the Allen Park and SWHS monitoring sites, despite their close prox imity, also suggests the sources of the elevated concentrations at SWHS are loca ted between the two sites. To further evaluate this idea, SWHS monitor data can be graphed against Allen Park data. If sources are affecting both monitors simila rly (i.e., such as a distant source), the data points should show a strong coupling or correlation around a central axis. If there is no coupling and dat a tends to congregate along the axis, it means one monitor has high values when the other has low values. Since Allen Park is typically upwind of SWHS when the highest 1-hour average SO 2 concentrations are observed, the sources would have to be located between the two monitors. Figure 4 shows there is a weak coupl ing or correlation between high SO 2 concentrations at the Allen Park and SW HS sites, which supports, along with other information in this WOE, that SO 2 sources located nearby are likely culpable.Page 6 Figure 4. Hourly SO 2 for Allen Park plotted against SWHS for all data and truncated at 100 ppb to show greater detail.

The large concentration differences in these nearby monitors indicate high spatial variability of SO 2 . The SWHS monitor is lo cated very near major SO 2 sources in Wayne County (see Figure 5). The MDEQ’s recommended nonattainment area is supported by the spat ial variability of SO 2 and the identifi cation of major sources discussed further below.

Emissions-Related Data

Figure 5 shows the location of SO 2 sources in Southeast Michigan with either actual or permitted emissions of 10 t ons or more. Wh ere permit data was available, allowable limits were used. If allowable limits were not available, reported emissions inventor y data for 2009 were used. Figure 6 shows the sources in Wayne County, along with the recommended nonattainment area. The red dots indicate sources either em itting or permitted to emit more than 1,000 tons per year of SO 2 . The orange dots indicate sources between 100 and 1,000 tons per year of SO 2 . The yellow dots indica te sources between 10 and 100 tons per year of SO 2 . Sources in Southeast Michigan emitting more than 1 ton of SO 2 in 2009 are shown in Appendix A. Sources in Wayne CountyPage 7 emitting more than 1 ton of SO 2 in 2009 are shown in Appendix B, including their distance and direction fr om the SWHS monitor.

The recommended nonattainment area contains most of the SO 2 sources emitting more than 100 tons in Wayne C ounty. Directly south of the SWHS monitor is Zug Island, which is located in the city of River Rouge. This small island contains the iron making portion (including blast furnaces and coke battery) of one of the two steel mills in the Detroit area. The remaining steel making facilities (basic oxygen furnaces and other processing) occur further south in the city of Ecorse, Michigan. Ju st south of Zug Island is one of the four power plants included in the MDEQ’s recommended nonattainment area. Two other power plants are located 10 and 20 km SSW of the SWHS monitor along the Detroit River. Located within five m iles south and west of the SWHS monitor are the other Detroit area steel mill, the fourth power plant, a wastewater treatment plant, a petroleum refinery, an asphalt plant, and a lime processing plant. All of these sources are included in the recommended nonattainment area (see Figure 6).

Another potential source of SO 2 emissions at SWHS is marine traffic along the Detroit River. This river is the only point of access to three of the Great Lakes. The SWHS monitor is located less than tw o miles from the ri ver, and the main passage for the river is directly south of the monitor. Thousands of ships navigate the river each year, many of wh ich traditionally have burned high sulfur bunker oil.Page 8 Figure 5. SO 2 sources in Southeast Michigan.

Emissions and Meteorology

Meteorology, wind direction, and wind speed, in particular, indicate movement of air around a particular point. Wind roses are particularly useful in visualizing where winds are coming from (wind dire ction) and how fast winds are moving (wind speed). The size of the bar i ndicates the frequency or how often the wind is at that particular speed and direction.

Wind roses were created using meteorologi cal data from 2008-2010 collected at each of the two monitor locations. The wind roses for Allen Park and SWHS indicate winds from all directions, but more so from the south and west (see Figure 7).

Pollution roses indicate the wind direction of high concentrations of a pollutant. They are similar to wind roses, except that the wind spe ed is replaced by pollutant concentration. High pollutant concentrations in a particular wind 10-100 tpy sources

Pollution roses were created for both monitors using 2008-2010 data. The majority of hours were below 5 ppb of SO 2 (96.97% of Allen Park’s data and 92.06% of SWHS’s data was below 5 ppb) at both sites. To emphasize the high days, a threshold va lue of 5 ppb of SO 2 was used. Although the NAAQS is set at 75 ppb, using a 75 ppb threshold woul d not provide enough data to create pollution roses, thus, 5 ppb was used.

Allen Park shows northeast to sout h wind directions during hours when SO 2 concentrations are above 5 ppb. SWHS show s a distinct southerly wind direction when SO 2 concentrations are above 5 ppb (see Figure 8). As seen in Figure 5, eastern Wayne County is very industria lized with several large sources of SO 2 south of SWHS and east of Allen Park along the river. Less than two miles directly south of the SWHS monitor is an iron making facility, a coke battery, a power plant, and the Detroit Riv er, which greatly increase SO 2 concentration at that monitor. The major sources of SO 2 are more than three miles away and downwind of the Allen Park monito r and, thus, have little influence on SO 2 concentrations at that monitor.Page 11 Figure 7. Wind roses for the SWHS and Allen Park monitors for 2008-2010.

Allen Park SWHSPage 12 Figure 8. SO 2 concentration roses showing wind direction during hours with SO 2 greater than 5 ppb.

Another analysis that is similar to a concentration rose is called a one dimensional nonparametric wind regression (NWR). NWR estimates the expected value of concentration as a func tion of wind direction (Kim and Hopke, 2004). It is similar to a pollution rose but with more robust mathematical support. NWR results can be multiplied by the wi nd direction frequency distribution to determine the contribution of eac h wind direction to average SO 2 mass. This analysis is particularly useful for i dentifying sources and their emissions strengths.

NWR was performed for both SWHS ( Figure 9) and Allen Park ( Figure 10). The SWHS NWR indicates sources directly s outh of SWHS strongl y influencing that monitor. The SO 2 concentrations from the south are increased by about 20-25 ppb compared to other wind directions . Also, sources northeast, east, and southeast of Allen Park cause a 2- 6 ppb increase compared to other wind directions. Both of these NWR show excess SO 2 concentrations when winds are coming from Zug Island (see Figure 9 and Figure 10). SO 2 conc (ppb)Page 13 Figure 9. Nonparametric wind regre ssion for SWHS. Rings are 5 ppb.

Figure 10. Nonparametric wind regression for Allen Park. Rings are 2 ppb.

Another analysis using two-dimensi onal nonparametric regression was performed on SO 2 data from three sites near De troit – Allen Park, SWHS, and Windsor West (Canadian site) for t he 2008-2010 period. This approach can indicate the direction in which source s are located but cannot indicate the distance of sources from the monitor location.

Each site has a strong directional pattern when SO 2 is high: SWHS is influenced when winds are from the s outh, Allen Park when winds are from the northeast, and Windsor when winds are from the southwest. Figure 11 shows the Zug Island

Zug IslandPage 14 centerlines of the dominant source direction from each monitor. They intersect on and around Zug Island, which fu rther indicates that an SO 2 source(s) there is affecting each of the monitors. As stat ed previously, Zug Island has a steel mill and coke battery and just south of the island is a power plant.

Geography/Topography

As one of the EPA’s 5 factors to be used for defining a nonattainment area, geography and topography were consider ed. There are no geographic or topographic barriers in this area to affect the nonattainment boundary.Page 15 Jurisdictional Boundaries

Jurisdictional boundaries are to be cons idered as one of the EPA’s 5 factors. The recommended nonattainment area incl udes a portion of the eastern and southern boundary of Wayne County with the remaining boundaries being major roadways.

Conclusions

The above data supports t he MDEQ’s recommended SO 2 nonattainment area. The area extends somewhat north to follo w a major road, Michigan Avenue, but excludes all areas north of Michigan Avenue. The main focus is directly south of the SWHS monitor based on pollution roses and nonparametric regression analysis. Since the Allen Park monitor is showing attainment, the nonattainment area should include areas east of the Allen Park monitor while still capturing the largest SO 2 sources in Wayne County.

Highways and the county borders we re used as boundaries for the nonattainment area because they are eas ily identified and follow the general location of the large SO 2 sources in Wayne County. The Wayne County border was used on the south end of the re commended nonattainment area since no highways were available as a boundary. The Allen Park monitor indicates high SO 2 concentrations from easterly winds, justifying the western boundary to be near the Allen Park monitor. T he SWHS monitor indicates highest SO 2 concentrations when winds are directly south. The southeast corner of the Wayne County is directly south of the Allen Park monitor and further south is Lake Erie (see Figure 5). Based on this WOE, high SO 2 concentrations are not observed when winds are from the west or southwest, therefore, sources or counties west and southwest of the Allen Park monitor should not be included in the nonattainment area.

Based on the above data, the MDEQ re commends the nonattainment boundary described in Figure 1 of this document.Page A-1 Appendix A
