Dear Administrator McTeer Toney:

As Technical Secretary to the Tennessee Air Pollution Control Board, I am forwarding correspondence to you from the Knox County Air Quality Management Agency dated July 24, 2015. That letter requests that the Tennessee Air Pollution Control Board withdraw several SIP submittals to EPA that it approved at the request of Knox County. These SIP submittals are detailed in the Knox County letter and the decision to withdraw them arose after discussions with EPA regarding the cleanup ofback logged SIP revisions at EPA.

I have determined that these requests are administrative in nature and within the scope of my authority as the Board's Technical Secretary. By copy ofthis letter, I am contemporaneously advising the Board ofthis action.

Thank you for your assistance in this matter. Ifyou or your staffshould have questions, please feel free to contact me at (615) 532-0525 or Director Liddington at (865) 215-5900.
Sincerely,

# q:7J**~~** Technical Secretary Tennessee Air Pollution Control Board
