### B. Martin Regional Administrator U.S. Environmental Protection Agency, Region 8 1595 Wynkoop Street Denver, CO 80202-1129 DearMr. Martin: On November 9, 20I0, EPA notified the Governor ofSouth Dakota that EPA revised the nitrogen dioxide National Ambient Air Quality Standard and initial area designations are due by January 25,2011. EPA revised the primary nitrogen dioxide standard by adding a I-hour average concentration. On January 18,20 11, Governor Daugaard submitted a letter to you designating the Secretary of the Department ofEnvironment and Natural Resources as his designee for submitting designations and other matters which involves South Dakota's Air Quality Program. In that capacity, I recommend EPA designate all counties in South Dakota as attaining the I-hour nitrogen dioxide standard (see Attachment I). Attachment 2 provides the supporting data for designating all ofSouth Dakota's counties in attainment and Attachment 3 is a copy ofthe Air Quality System AMP450 report showing the yearly 98th percentile concentrations for each site and includes the one year ofdata collected near the Big Stone Power Plant. Thank you for the opportunity to propose designations for the revised primary nitrogen dioxide standard. Ifyou have questions, please contact Brian Gustafson at 605-773-3151.

### Attachment 2 Nitrogen Dioxide Monitoring Network in SouthDakota The first sampling effort to collect hourly nitrogen dioxide data was near the Big Stone PowerPlant. Acontinuous 12-month period ofair monitoring was completed near the facility in the years of2001 and 2002 as part ofa Prevention ofSignificant Deterioration permit application. Nitrogen dioxide levels were low with a 98th 

### percentile I-hour average concentration level of 15 parts perbillion. DENRoperates a network ofair monitoring sites which began collecting hourly nitrogen dioxide data in 2003. The first site was setup at the Hilltop Site in Sioux Falls. The monitor was later moved to the SD School Site and continues today. 

### In 2005, two more locations were added at the Badlands and Wind Cave National Parks. 

### In 2009, two more locations were added in Union County. The current sampling network includes sites in several counties around the state with goals ofhigh concentration, population, source impact, background and regional transport. SeeFigure 1for a map ofthe state showing the counties with nitrogen dioxide air monitoring data

### Nitrogen Dioxide Emission Sourcesin SouthDakota Nitrogen dioxide I-hour concentrations are low statewide. The highest design value concentration site is at SD School Site in Sioux Falls at 41 % 

### ofthe standard. The Badlands and Wind Cave Sites have the lowest design value concentrations at 4% ofthe standard. The concentrations are low for two reasons. First, the state's population is low and therefore traffic counts are also low

. Second, a majority ofthe industries in South Dakotado not emit high amounts ofnitrogen dioxide emissions

. South Dakota's population is one ofthe lowest state populations in the nation with a 2010 census of 814,180. The largest city in South Dakota is Sioux Falls with a population ofless than 150,000. The largest ofthe three Metropolitan Statistical Areas (MSA) in the state includes the city ofSioux Falls and the counties ofMinnehaha, Lincoln and Turner. Thecombined estimated 2009 population for the Sioux Falls MSA is 232,503. Table 1provides a list ofthe top 10 most populated counties in the state and the largestcity within the county. 1',

### Total TonsofNitrogen Dioxide 17,826 Nitrogen Dioxide Concentrations in South Dakota Table 3 shows the three year calculated design value concentration for each site. Thedesign value concentration for the SD School and Badlands Sites used data from 2008 to 2010. Because ofa low percentage ofvalid data recovery at Wind Cave in 2010 the data from 2007 to 2009 was used for Wind Cave Site. Both Union County sites have only two years ofdata.

### The nitrogen dioxide I-hourconcentrations collected in the state during the years of2007 through 2010 show no I-hour concentrations exceeding the new primary standard as calculated following the form ofthe standard. The highest three year average was recorded at the Sioux Falls SD School Site with an average concentration level of41 parts per billion. Figure 2 provides a comparison ofthe design values for each site compared to the I-hour nitrogen dioxide standard. Although the Union County#1 and #2 Sites do not have three years ofdata yet, the two year average ofthe 98th 

### percentile is provided for comparison purposes.
