Dear Mr. Sheffy:

Thank you for submitting a request to waive the new PM10 monitoring requirement of 1 in 3 day to 1 in 6 day sampling. Upon initial review of your analysis, a discrepancy existed between your results and the regional office’s. After a thorough conversation with the DNR staff member who had conducted the analysis, it was noted that the software used did not perform the operation as required by regulation. The problem was rectified, the data reanalyzed and the results agreed with the regional office’s. Below is a listing of those sites which have been approved to continue sampling once every sixth day.
550250025 Madison
550250037 Dane Co. Landfill
550310020 Superior
550310025 Superior
550730013 Wausau
550790059 Milwaukee
550790064 Milwaukee
551230008 Wildcat Mountain
551250001 Boulder Junction
551330018 Waukesha
551330027 Waukesha

We appreciate the work your staff did in providing a rapid response and hope to continue working closely with you to successfully implement the new fine particulate network.

If you have any questions, please contact Michael Rizzo, of my staff, at (312) 353-6324.

Sincerely,
