NOTICE OF PETITION FOR EXCLUSION OF PMlO MONITORING DATA AFFECTED BY AN EXCEPTIONAL EVENT ON SEPTEMBER2,2006, APRIL 12, 2007 AND JUNE 5,2007

In March 2007, the U.S. Environmental Protection Agency (U.S:EPA) adopted 40 CFR Parts 50 and 51, Treatment of Data Influenced 

### by Exceptional Events. This regulation gives states the authority to exclude air quality monitoring data from regulatory determinations relatedto exceedances or violations of the, National Ambient Air Quality Standards (NAAQS). Under this rule, a local air district may "flag"'violations of the PMIO standard caused by a qualifying natural event and upon documentation flagged datawillbeexcludedfromthe noncompliance determination of the PMlO standard.
On September 2, 2006, three lmperial County alr monitoring stations recorded PMIO concentrations In excess of the federal 24-hour PMIO standard. These air monitor~ng stations and their respective 24-hour PMIO concentrat~ons are as follows: Calexico-Ethel Street with 164Fglm3, Calexico-Grant Street with 233Fglm3and Westmorland-W 16'Street with 167FglmJ.;

OnApril 12,2007,two lmperial County air monitoring stations recorded PMIO concentrations in excess of the federal 24-hour PMIO standard. These air monitoring stations and their respective 24-hour PMIO concentrations are as follows: Brawley-Main Street with 291Fglm3and Westmorland-W 1" Street with 1 67Fglm3.

On June 5, 2007 five lmperial County air monitoring stations recorded PMl0 concentrations in excess of the federal 24-hour PMIO standard. These air monitoring stations and their respective 24-hour PMIO concentrations are as follows: Calexico-Ethel Street with 282Fglm3, Brawley-Main Street with 281Fglm3,Westmorland-W 

### Is' Street with 226Fglm3, ElCentro 

### 9"' Street with200Fglm3and Niland English Roadwith 162Fglm3.

A review of the meteorologicaldata for these events indicates that measured high winds in the Imperial County were the main factor that contributed to the violationsofthe PMIOstandard. Therefore, the PMIO measurements on September 2, 2006, April 12,2007 and June 

### 5, 2007 at the lmperialCountyair monitors meet the criteria for naturalevents exclusion.

The Public has an opportunity to review and submit' comments on the district's petition for exclusion of these events. Written comments will be received by the ICAPCD for a period of thirty (30) days after publication of this notice. This petition and supporting documentation may be examined at the Air PollutionControl District Office, 150 South Ninth Street, ElCentro, CA 92243.
