Dear Ms. Eagan:

I wish to commend you for the efforts that have been given to the implementation and deployment of Wisconsin’s PM2.5 monitoring network.

I would like to convey my concerns with Wisconsin’s PM2.5 data completeness. To date, none of Wisconsin’s calendar 1999 PM2.5 data has been entered into the Agency’s Aerometric Information Retrieval System (AIRS). The State’s PM2.5 program must comply with the regulations contained in 40 CFR, Part 58 Section 35 which states that the data must be submitted to AIRS ninety days after the end of the reporting period which is the calendar quarter. To date, none of Wisconsin’s Calendar Year 1999 PM2.5 data has been entered into the AIRS database.

Please be aware that this program has had special emphasis placed on it by Congress and will be reviewed as a part of the Government Performance and Results Act. Because of this, it is of the utmost importance that compliance with the regulatory requirements is maintained by all States receiving Section 103 funds to implement the PM2.5 monitoring program.

I realize that the State was not able to monitor for first quarter of 1999. However, I am requesting that Wisconsin submit a time line as to when the data from the first through third quarters of Calendar year 1999 will be submitted to AIRS as well as an assessment of whether or not the Calendar Year 1999 fourth quarter data will be entered by the required due date of
March 31, 2000. A response to these inquiries would be appreciated by December 31, 1999.

I appreciate the efforts you have put forth to establish and operate the PM2.5 monitoring network. If there is any assistance that we could provide to you to overcome this last hurdle, please do not hesitate to ask.

Sincerely yours,


Margaret M. Guerriero, Acting Director
Air and Radiation Division
