### CERTIFICATIO N OF THE 2008 OZONE INFRAST U R CTURE STAT E IMP LEMENTATION PLAN When EPA revises or adds a new National Ambient Ai r Quality Standard , secti on 110 oft he federal Clean Air Act (42 USC 

### § 741 0) requires the state to rev iew its current regu l ations and make the necessary changes to ensure the state 's air po llution control program can imp lement, maintain, and enforce the revised or new National Ambient Ai r Qua li ty Standards. The South Dakota Department of Env ir onment and Natural Resources (DENR) completed a review of the Jaws and regulations for the Air Pollution Control Program as it relates to the implementation, maintenance , and enfo r ce ment of the 2008 revised Ozone National Ambient Air Quality Standard. The review finds that all the necessary changes to the reg ulati ons have been completed and no state Ja ws or ru l es will need to be changed to implement the 2008 revised Ozone sta ndard. DENR certifies that South Dakota i s implementing the 2008 revised Ozone standard and is meeting a ll the requirements in sec ti on II O(a)(2)(A through H and 

### J thr o ugh M) of the Clean Air Act. /\11 state regulation changes go th rou gh the department 's public notice procedures, board approval and were adopted into state regulati ons. The following information describes the regulations and how DENR is implementing the 2008 revised Ozone National Ambient Air Quality Standard in South Dakota.

### State of South Dakota Infrastructure State Implementation Plan for 2008 Ozone National A mbi e nt Air Quality Standard 1. 0 Introduction On March 12, 2008, EP A revised the ozone stan dard lowerin g the concentration level to 0.075 parts per million wh ic h triggered the submittal of an infrast ructure State I mplementation Plan (S JP) f r om each state to EPA by March 12, 20 II. On September 16, 2009, EP A announced in a press rel ease it was reconsidering the 2008 ozo n e standard and proposed staying the 2008 sta nd ards for th e purpose of atta inm ent a nd non-attai nm e nt area de s ignation s . Alth ough the sc hedule for states to submit their in f rast ru cture SIP was not addressed in the press releas e, a majority of states believed the requirement fo r s ubmitting the infrastructure S IP was also stayed. In a memorandum dated September 22, 20 I I, from Gina McCarthy to th e EPA regions, EPA outlined the implementati on steps moving forward for states and local a ir agencies co ncerning EPA's rec e nt decision to retain the 2008 ozone standard. Again, EPA did not address the schedule for states to subm it their infras tructure SI Ps. On Ap ril 30 , 20 12 , EPA notified states of EPA's 2 008 ozone standard designation s. On October 17, 2012, t h e United States District Court, Northern District of Californ ia , agreed with the plaintiff s WildEarth Guardian s, Midwe st Env iro nmental Defense Ce nter , and S ierra Club that the states listed in the filing fa iled to submit infrastructure SIPs for the 2008 ozone standards

. The cour1 o rder EPA t o sign a final rule o r rule s i ssuing find ings of failure to sub mit for each state in the petition, South Dakota included, no l ater than January 4, 2013

. Once EPA publishes this finding, EPA has 24 months to promulgate federal implemen t ation plans (F JP) to add r ess th e outstandin g S IP elements unless the affec ted state submits an EPA approved S IP tha t co rrects the defic i ency. A lthough South Dakota disagrees with the timeline establ ished by the court and believes the infrastructu re SIP is required with in three years of EPA decision to r etain the 2008 ozone standard or September 2014. South Dako ta is committed to working with EPA on the deficiencies in a timely manne r . The purpose of thi s SIP s ubmittal is to address the deficiencies. The information included in thi s doc ument certifies that Sou th Dakota i s meeting the requirements in sect i o n I I O(a)( I) and 11 O(a)(2) of t h e Clean Air Act

. Attachment A provides a l ist of eac h section in the Adm ini strat i ve Rules of South Dakota (A R SD) Art icle 74 : 36 (Air Po llution Cont rol Program) that is part of South Dakota's SIP , the effective date of each section, and EPA's last approval of eac h section.

### 2.0 Section llO(a)(l) Requirement Summa1y "Each State shall, after reasonable notice and public hearing, adopt and submit to the Administrator,[.

. .} a plan which provides for implementation, maintenance, and enforcement of such primary standard in each air quality control region (or portion thereof) with such State. " So uth Dakota's Infrastructure In acco rd ance with Sou th Dakota Co difi ed L aws (S DCL) 1- 26, after reasonab l e notice fo r publi c co mment, proposed rul e changes are pre se nted to the Boa rd of Mineral s and Env ironment during a public hearing. The rules if app r oved b y the Boa rd arc then s ubmitted to the State's Interim Rule s Co mmittee fo r approva l. Once approved by the Co mmittee , the rules are presented to th e Secretary of State and are final. O nce the rules are fi nal, DENR submits the changes to EPA as part of the State Implementation Plan with the documentation necessary to demonstrate the changes were approved in accordance with state procedures. Currently, DENR has s ubmitted the following S I P changes to EPA related to the revised 2008 ozone standa rd: I. Jun e 14 , 20 I0- D ENR su bmitted revi sio ns t o So uth Dakota's State Impl ementa t ion Pl an (S IP) which includes an air qua lity construction permit program and revisions to the rule s wh i ch adopt 40 Code of Federal Regulations in P arts I to 99 as published on Jul y 1 , 2009. These rule changes adopted the new federal Nationa l Ambient Air Quality Standards for ozone. DENR is wa i ting for EP A to approve this S IP submittal ; 2. J anuary 21 , 20 II

- DENR submitted South Dakota 's R egional Haze Program as part of South Dakota 's S IP

. DENR submitted rev is i ons to the program on September 19,20 11. On April26 , 2012, EPA comp leted a full approval of th e South Dakota's Regional Haze Program in South Dakota ' s SIP; and 3. June 20,2011- DENR subm itted r evisio ns t o So u th Dakota's S IP which adopt EPA 's g reenh ouse tailoring rule and revi sions to the constructio n permit program. DENR is waiting for E PA to approve thi s S IP submittal. The SIP submi ttals that have not been approved by EPA yet are reflected in Attachment A.

Under the se rules , DENR ope r ates a
3network of air monitoring sites. Authority used to promulgate these rules is conta ined in SDCL 34A-I-6 and 34A-1-l5. The need for addi ti onal air monitoring sites to test for ozone levels are assessed each year as part of South Dakota's Annual Netwo rk Plan as required in 40 Code of Federal Regulations (CFR) section 58.1 0. The public is provided a 30 day period to comment on the proposed changes to South Dakota's ambient monitoring network before i t is finalized and subm itted to EPA for approval. The Annual Network Plan is available on DENR's website at: http: // denr.sd.gov / des /ag / monitoring/state-mo.aspx

T h e ambient data, compared to the Nati ona l Ambient Air Quality Standards in South Dakota , are collected using EPA's designated federal reference method monitors as specified in 40 CFR Part 50 or federal equivalent method monitors as specified in 40 CFR Part 53. DENR submits the ambient data to EPA's Air Quality System (AQS) database as required by 40 CFR Part 58. The ozone monitoring requirements in 40 CFR Part 58, Appendix D, Table D-2 identi fies the minimum number of ozone monito rs in each state f or a Metropolitan statistical area (MSA) with a population equal to or greate r t han 50 ,000

. South Dakota has two MSAs that meet the requirement in Table D-2 and they are Rapid City and Sioux Falls. South Dakota is meeting the minimum monitoring requirements of two ozone monitoring site in Rapid C ity and Sioux Falls. In addition, South Dakota operates four more sites that collect data on ozone concentrat i ons in the state. One site is l ocated near the C ity of Brookings which is located on the eastern edge of South Dakota near the Minnesota bo rder. The remaining three sites arc in rural areas with small populations and are transp o rt oriented sites. Two of the ozone monitors are located on the western side of South Dakota (i.e., Badlands and Wind Cave National Parks). The th ird site is located in the southeastern co rner of South Dakota which borders Iowa and Nebraska. 3

5South Dakota has a fully S I P approved PSD pr ogra m and has successfu ll y implemented this program for many years. After a 30 day publ ic comment period, a pu blic hearing on February 17 , 2011 , and Interim Rules Committee rev i ew on March 29,2011 , the federal Tailoring Rule p r

ovisions that were promulgated by E PA on June, 3 , 2010 we re incorporated in South Dakota 's Prevention of Significant Deterio r atio n pr ogram in ARS D Chapter 74:36:09. The change became effective on Ap r il 20, 20 II. The Tai l o ri ng Rule c h anges were submitted to EPA for approval on June 20,2011 and EPA has not yet acted on th is subm ittal. Tn addition, South Dakota has a fully SIP approved Reg i onal Haze Program and is waiting on EPA to approve South Dakota 's a ir quality const ruction perm it program in the State L mpleme n tat i on Pla n . O tter Ta il Power Company's B i g Sto ne I power p l a n t em i ts t he hi ghest em issions of nitrogen oxides, an ozone forming precurso r, which is one of the ozone forming pollutants in South Dakota. In June 2012 , Otter Tai l Powe r Company commenced construction of its Air Quality Control P r oject. The control project consists of insta l ling an upgraded bag house, a dry fl ue gas desulfurization system, and a selective catalytic reduc tion system a n d will be used to meet the best avai lab l e retr ofit technology requ ire m ents of the Regiona l Haze program . Once com pleted , Otter Tai l Power Company will reduce i ts emiss i o ns of both sulfu r d iox i des and nitrogen oxides by approximately 16,000 tons pe r year per pollutant.

The state is the 17th largest in the nation with a surface area of 77,116 square miles. The two large st cities in the state arc Sioux Falls (156,592) o n the sou theast edge and Rapid C ity (69,200) on the west central edge of the state. South Dakota's remaining population is sp readoul throug hout the s tate with a majority on the eastern half of the state

### B .2 State Emissio n s Invento ry The air pollutants that form ozone are volatile organ i c compounds and nitrogen oxides. There were 85 sources in South Dakota in 20 I I that had a Tit l e V air quality opera t ing permit and reported an nu al air emissions. The total nitrogen oxide and volatile organ ic compound emissions in 20

. 11 from these sources was 14,070 and 3,315 tons, respectively. Ofthe I4 ,070 tons of nitrogen oxide, Otter Tai l Power Company's Big Stone I coa l-fired electric power plant l oca ted in the northeast corner of the state was the major em itter at 9,825 tons. There was no major emitter of vo l atile organic compound emissions. T here were eight sources which emitted over I 00 tons and ranged from I I 0 to 295 tons in 2011. Seven of those sources are located on the eastern edge of South Dakota while the eighth is located on the western edge of South Dakota. Table B-1 through B-7 contains a list of the a ir emissions from sources considered major sources in South Dakota under the Title V a ir qua lity ope rating permit program that potentially could impact a ir quality in neighboring states.

B- 5As represented in the tables, the largest emission source for nitrogen oxides is Big Stone (Otte r Tail Power) in Grant County on the northeastern edge of the state. This facility as stated in Sec ti on 3.4 of this document is currently installing new control devices as required by the Regional Haze Program which is part of South Dakota's SIP. The new control devices will significantly reduce the amount of nitrogen oxide emissions by 70% per year from this facility. Another future reduction in emissions will come from Black I till s Power and Light's Ben Fench facility in Rapid City which has the third highest emission level of nitrogen oxide. Black I I ill s Power's Ben French facility is located in the western s ide of the state and their current plan is to shutdown the coal fired boiler at the faci li ty by 2014. This change will decrease emission levels down to around 20 tons of nitrogen ox ide per year from the Ben French facility. 

### B.3 South Dakota Metero lo gy South Dakota's ozone season occurs from April I t o September 30. Pred ominate wind direction during these months in Rapid City (see Figure 8.1 and 8.2) on the west s id e of the state blow from the northwest. The predominate w ind direction for the Brookings area (sec Figure 8.3) on the east side of the state is from the sou th southeast. Major weather systems move mainly from west to east through the state. 

### 8.4 Non-attainment Areas in Neig hb ori ng States 1\s stated earlier, So uth Daktoa is attaining the 2008 ozone National Ambient Air Quality Standards. Only one state bordering South Dakota has a non-attainment area for ozo ne and it is located in Sublette County in so uthwe stern Wyoming. See the map in Attachment C. Sublette County has the unusual event of having the highest ozone levels during the winter months of February and Marc h

. Rapid City is the closest location in South Dakota to the Wyoming non-attainment area that has major Title V perm i tted facilities with ozo ne forming emissions. During the winter months the predominate wind direction is from the northwest in Rapid City. See Figure B. I for a windrose of the weather data collected in R apid City. Sublette County in Wyoming is around 340 miles south west of Rapid City and predominate winds from the northwest wou ld blow air pollution emissions away from the Wyoming ozone non-attainment area. Even if weather conditions blew in the direction of Sublette Coun t y, there are mountain ranges between Sublette County and Rapid City which would hinder air pollution from South Dakota impacting Sublette County's air quality. The c l osest ozone non-attainment area to Sou th Dakota is located southwest of the state in cou nti es of northeast Colorado, east of the front range of the R ocky Mountains (beginning about 260 miles to the southwest of Rapid City). The Co lorado nonattainment area has the highest ozone concentrations recorded in the s ummer months.

The 2008 ozone National Amb ient Air Quality Standards are being attained throughout South Dakota. One of the main reasons South Dakota is attaining the sta ndard is its population and air emissions of ozone forming pollution is relatively small compared to states with ozone n o n-attainment problems. South Dakota is not impacting no n-attainment or maintenance areas in other states for ozone. DENR bases this statement on South Dakota ' s air emission inventory , meterological conditions, and the distance and location of n on-at tainment areas in other states. The closest non-atta i nme n t areas are located southwest to west of South Dakota while a majority o f South Dakota 's ozone forming air pollution (i.e., nitroge n oxide and volatile o rgranic compounds) is em itted o n the eastern side of the state. Predominate wind direction during the ozo ne seaso n keeps air pollutants on both sides of the state from being blown to the ozone non-attainment areas which are hundreds o f miles from South Dakota. Even if the wind blew in those directi ons, the distance to the non-attainment areas, along with mountain ran ges in so me cases , would dilute the a i r pollution to a point if it d i d reach the non - atta i nment area, it would hav e minimal impact

B-9The information above clearly shows South Dakota is not significantly impacting nonattainment areas in other states and as South Dakota's Regional Haze Program is implemented, impacts from South Dakota will be even less. This i s confirmed by EPA in a letter to Governor Dennis Daugaard , dated April 30, 2012. ln the letter, EPA states , "After reviewing the most recent certified ozone air quality data for your state and evaluating factors to assess contribution to nearby levels of ozone, J am pleased to inform you that no areas in South Dakota violate the 2008 standards or contribute to a violation ofthe ozone standard in a nearby area."
