Dear Mr. Mathur:

Thank you for submitting a request to waive the new PM10 monitoring requirement of 1 in 3 day to 1 in 6 day sampling. The required analysis was conducted at Region 5 to verify continuing the 1 in 6 day sampling frequency at those sites listed in your request. After further consultation with Lee Byrd of the Office of Air Quality Planning and Standards, the two sites (170310014 and 170310070) listed in the OAQPS guidance as being ineligible for a waiver have been granted the waiver due to an exceptional event occurring at both locations on the same day. Below is a listing of the approved sites which can continue to sample once every sixth day.
