Governor Daugaard delegated the authority to submit the state implementation plan documents 

for South Dakota to the Secretary of the Department of Environment and Natural Resources 

(DENR). In that capacity, I am submitting the enclosed demonstration certifying South Dakota 

adopted the necessary rules and can show the state is meeting all the Clean Air Act requirements 

in sections l lO(a)(l) and (2) for the revised PM2.5 annual standard promulgated in 2012. 

The certification demonstration was put out for public review and comment on the Air Quality 

and the department's webpages for 30 days starting on December 21, 2015. No comments or 

request for a public hearing was received as a result of the review period. 

The enclosed document and attachments will provide further information concerning the state 

laws and regulations adopted by the state through the public notice and hearing process. No 

additional law or rule change were required to implement and maintain the revised 2012 PM2.5 

annual standard. 

Thank you for your assistance in completing the process. We look forward to your approval of 

the certification of the state implementation plan. If you have questions on this report, please 

contact Brian Gustafson at 605-773-3151 for more information.
