### CERTIFICATION OF THE 2012 PM2.5 ANNUAL STANDARD

INFRASTURCTURE STATE IMPLEMENTATION PLAN

When EPA revises or adds a new National Ambient Air Quality Standard, section 110 of the

federal Clean Air Act (42 USC § 7410) requires the state to review its cu rrent regulations and

make the necessary changes to ensure the state’s air pollution control program can implement,

maintain, and enforce the revised or new National Ambient Air Quality Standards.

The South Dakota Department of Environment and Natural Res ources (DENR) completed a

review of the laws and regulations for the Air Pollution Control Program as it relates to the

implementation, maintenance, and enforcement of the 2012 revised PM 2.5 annual National

Ambient Air Quality Standard. The review finds t hat all the necessary changes to the regulations

have been completed and currently no state laws or rules will need to be changed to implement

the 2012 revised PM 2.5 annual standard. DENR certifies that South Dakota is implementing the

2012 revised PM 2.5 annual standard and is meeting all the requirements in section 110(a)(2)(A

through H and J through M) of the Clean Air Act.

All state regulation changes go through the department’s public notice procedures, board

approval and were adopted into state regul ations. The following information describes the

regulations and how DENR is implementing in South Dakota the 2012 revised PM 2.5 annual

National Ambient Air Quality Standard.1 

### State of South Dakota

Infrastructure State Implementation Plan

201 2 PM 2.5 

### Annu al National Ambient Air Quality Standard

1.0 Introduction

On Dec ember 13 , 20 12 , EPA revised the PM 2.5 annual standard by lowering the concentration

from 15 to 12 micrograms per cubic meter ( ug/m 3 ) which triggered the submission of an

infrastructure State Implementation Plan (SIP) from each state to EPA by December 13, 2015.

On December 13 , 201 3 , the South Dakota Department of Environment and Natural Resources

(DENR) submitted designation recommendations of attainment of the revised 2012 PM 2.5 annual

stan dard for all counties in South Dakota. On August 19, 2014, EPA notified South Dakota that

collected data did not indicate any violations or contribution to nearby areas and published in the

Federal Register that all counties in South Dakota be designated f or the revised 201 2 PM 2.5

annual standard as unclassifiable/attainment.

This document certifies and demonstrates that South Dakota is meeting the requirements in

section 110(a)(1) and 110(a)(2) of the Clean Air Act. Attachment A provides a list of each

section in the Administrative Rules of South Dakota (ARSD) Article 74:36 (Air Pollution

Control Program) that is part of South Dakota’s SIP, the effective date of each section, and

EPA’s last approval of each section. Attachments B provides information de monstrating that

South Dakota ’s PM 2.5 emis s ions do not affect any PM 2.5 nonattainment or maintenance areas for

the revised annual standard located in neighboring states.



### 2.0 Section 110(a)(1)

Requirement Summary

“Each State shall

, after reasonable notic e 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.”

South Dakota’s Infr astructure

In accordance with South Dakota Codified Laws (SDCL) 1

- 26, after reasonable notice for public

comment, proposed rule changes are presented to the Board of Minerals and Environment during

a public hearing. The rules if approved by the Board are then submitted to the State’s Interim

Rules Committee for approval. Once approved by the Committee, the rules are presented to the

Secretary of State and are final

. Once the rules are final, DENR submits the changes to EPA as

part of South Dakota’s SIP wi th the documentation necessary to demonstrate the changes were

approved in accordance with state procedures.

Currently, DENR submitted the following SIP changes to EPA related to the revised 20 1 2 PM 2.5

annual standard:2

1. June 14, 2010

– DENR s ubmitted revi sions to South Dakota’s S IP which includes an air

quality construction permit program and revisions to the rules which adopt 40 Code of

Federal Regulations in Parts 1 to 99 as published on July 1, 2009. E PA approved the SIP

changed on July 7, 2014 ;

2. Januar y 21, 2011

– DENR s ubmitted South Dakota’s Regional Haze p rogram as part of

South Dakota’s SIP. DENR submitted revisions to the program on September 19, 2011.

On April 26, 2012, EPA completed a full approval of the South Dakota’s Regional Haze

p rogram in S outh Dakota’s SIP; and

3. On Octo ber 2 3 , 2015

– DENR submitted revisions to the rules which adopt 40 Code of

Federal Regulations in Parts 1 to 99 as published on July 1, 2014. The rule changes

adopted the 201 2 PM 2.5 annual standard. DENR is waiting for EPA to approve this SIP

submittal.

The SIP submittals that have not been approved by EPA are reflected in Attachment A.

n ecessary or appropriate to meet the applica ble requirements of this chapter; ”

South Dakota’s Infrastructure

Based on South Dakota’s ambient air monitoring network, South Dakota is attain ing the revised

PM 2.5 annual National Ambient Air Quality Standards throughout the state. Therefore, South

Dakota has not been required to adopt specific rules limiting PM 2.5 emissions from businesses in

South Dakota.

South Dakota ’s existing r ules are sufficient to implement and maintain the revised 20 1 2 PM 2.5

annual s ta ndard in South Dakota. The following is a list of those rules which have been approved

in South Dakota’s SIP or were submitted to EPA to be included in South Dakota’s SIP and

awaiting EPA’s approval :

2. ARSD Chapter 74:36:09 (Prevention of significant deterioration) ;

3. ARSD Chapter 74:36:20 (Construction permits for new sources and modifications) ; and

4. ARSD Chapter 74:36:21 (Regional haze program)

.

In addition, the following rules which have been app roved by EPA or delegated by EPA will also

be used to implement and maintain the 20 1 2 PM 2.5 annual s tandard in South Dakota:3

1. ARSD Chapter 74:36:05 (Operating permits for Part 70 sources);

2. ARSD Chapter 74:36:07 (New source performance standards);

l argest cities in the state are Sioux Falls (156,592) on the southeast edge and Rapid City (69,200)

on the west central edge of the state. South Dakota’s remaining population is spreadout

throughout the state with a majority on the eastern half of the stat e.



### B.2 State Emissions Inventory

The state’s national emissions inventory shows there were 804.7 tons of PM 2.5 emissions in

South Dakota in 2011 from sources with a Title V air quality operating permit. The total PM 2.5

emissions in the 2011 nationa l emissions inventory for South Dakota from poin t and non

- point

sources was 3,674.1 tons. Table B

- 1 through B

- 7 contains the estimated air emissions including

model source, sources considered major sources, non point sources of rail, airport, and mobile in

South Dakota that potentially could impact air quality in South Dakota and neighboring states.

As represented in the tables, emisiso ns levels are low throught the state and would have little

impact on levels in neighboring states

. T he county with the highest PM 2.5 emission is GrantB

- 4

County at 274.8 tons per year mainly due to the Big Stone I Power Plant w hich is operated by

Otter Tail Power Company in the northeastern edge of the state. The second and third highest

county emissions are in Pennington at 225.4 tons per year and Minnehaha at 221.3 tons per year

. They are the counties with the highest population density associated with s maller point s ource

emissions

. All the remaining counties have PM 2.5 emisisons less than 200 tons per year.



### B.3 South Dakota SIP Approved Programs

South Dakota has a SIP approved PSD program , a minor source operating permit program, a

construction per mit program and has successfully implemented th e s e program s for many years.

After a 30 day public comment period, a public hearing on August 20 , 201 5 , and Interim Rules

Committee review on September 2 1 , 201 5 , the latest update of the air quality regulat ion s was

complete. The updated state regulations in ARSD 74:36 became e ffective on October 13, 2015.

The updated regulations were submitted to EPA for approval to add to the SIP on October 23,

2015 . EPA has not yet acted on this submittal.

South Dakota has a SIP approved Regional Haze Program which was revised on June 25, 2013.

DENR submitted the revised Regional Haze Program to EPA for approval on July 29, 2013.

EPA approved the submittal on May 29, 2012

.



### B. 4 South Dakota Meterology

South Dakota ’s p redom inate wind direct ion is form the northwest and southeast during most of

the year

. M ajor weather systems move mainly from west to east through the state.



### B. 5 Nonattainment and Maintenance Areas in N eighboring States

On January 24, 2011, DENR submitted the proposed designations for the revised 201 2 PM 2.5

a nnual s tandard to EPA . In a response letter from EPA to Governor Dennis Daugaard, dated

August 19, 201 4 , EPA designated all areas of the state as unclassifiable/attainment for the 201 2

PM 2.5 annual st andard. Although EPA designated all of South Dakota as

unclassifiable/attainment; South Daktoa is attaining the 20 1 2 PM 2.5 a nnual s tandard.

There are no states bordering South Dakota that have a nonattainment or maintenance area for

the 201 2 PM 2.5 annua l standard

. The state with an area not attaining the standard closest to South

Daktoa is in northern Idaho upwind of our state. The next closest is in Ohio. Both are hundreds

of miles from South Dakota. See Figure B5

revised 2012 PM 2.5 standard

### B. 6 Conclusions

The revised 201 2 PM 2.5 a nnual s tandard i s being attained throughout South Dakota. One of the

reasons South Dakota is attaining the standard is its population and air emissions are relatively

small

.

The information above clearly shows South Dakota is not significantly impacting nonattainment

or maintenance areas in other states . As South Dakota’s Regional Haze Program is implemented

, impacts

, if any

, will be even less from South Da kota. DENR believes its Regional Haze program

in combination with its PSD program and air quality construction permit program ensures South

Dakota is able to regulate any new source or modification to existing sources to prevent it from

causing a nonattain ment area in South Dakota or significantly impacting a nonattainment area or

maintenance area in other states
