Re: 1 -Hour Nitrogen Dioxide (NOz) Designation Recommendation for the Pechanga Band of 

Luiseiio Indians 

Dear Mr. Blumenfeld: 

The Pechanga Band of Luiseiio Indians appreciates the opportunity to submit a recommendation 

for the designation of the National Ambient Air Quality Standard for NO2. In accordance with 

the appropriate provisions of sections 301(d) and 110(o) of the Clean Air Act, the Pechanga 

Band of Luisefio Indians recommends that the air quality management area within the Pechanga 

Reservation's exterior boundaries be designated as unclassifiable/attainment for the new 1 -hour 

NO2 standard. The unclassifiable/attainment request is based on Pechanga's estimation that the 

1 -Hour NO2 levels from data gathered since 2008 are not out of compliance with the 1 -Hour NO2 

standard; however, a full three years worth of data is necessary to make a final determination. 

The Pechanga Ambient Air Monitoring Station is located at the Pechanga Government Center on 

the Pechanga Indian Reservation, near Temecula, California. Data gathered for NO2 since the 3rd 

Quarter of 2008 through the 3rd quarter of 2010 have been validated, entered into the U.S. 

Environmental Protection Agency Air Quality System (AQS), and are summarized below within 

each year. The data currently indicates that the Pechanga Reservation will be in attainment for 

the new l-Hour NO2 standard as well as the Annual standard. The 4th Quarter 2010 data is in the 

process of validation, however, the summary of raw data has been provided for reference as 

preliminary results suggest that the station remains within compliance of the standards. 

2008 NO2 Summary: 

In 2008 the Pechanga Ambient Air Monitoring Station came online. The 3rd and 4th Quarters are 

summarized below as these are the two Quarters that collected complete data after station 

installation: 
3'd Quarter 2008: NO2 data recovery for the quarter was 91%. The NO2 average during 

the 3rd quarter was 4ppb.The highest 1 -hour average for NO2 during the quarter was 

30ppb and it occurred on September 25,2008. 

4th Quarter 2008: 1V02 data recovery for the quarter was 94%. The NO2average during the 

4th quarter was 7ppb. The highest 1 -hour average for NO2 during the quarter was 33ppb 

and it occurred on October 22,2008. 

2009 NO2 Summary: 

In 2009 the annual average was 5.2ppb and the 1-hour average was 27ppb. Each Quarter is 

summarized below: 

1" Quarter 2009: The NO2 data recovery for the quarter was 9 1%. The NO2 average 

during the quarter was Sppb, and the highest 1 -hour average was 27ppb which occurred 

on January 20,2009. 

2"d Quarter 2009: The NO2 data recovery for the quarter was 95%. The NO2 average 

during the quarter was 4ppb, and the highest 1 -hour average was 2 1 ppb which occurred 

on April 2 1,2009. 

3rd Quarter 2009: The NO2 data recovery for the quarter was 94%. The NO2 average 

during the quarter was 3ppb, and the highest 1-hour average was 27ppb which occurred 

on September 23,2009. 

4th Quarter 2009: The NO2 data recovery for the quarter was 95%. The NO2 average 

during the quarter was Sppb, and the highest 1 -hour average was 26ppb which occurred 

on December 28,2009. 

20 10 NO2 Summary: 

In 2010 the annual average is estimated at 3.7ppb and the 1-hour average is estimated at 23.5ppb. 

Each quarter is summarized below: 

1" Quarter 2010: The NO2 data recovery for the quarter was 92%. The NO2 average 

during the 1 st quarter was 4ppb. The highest 1-hour average was 25ppb, and it occurred 

on January 4,2010. 

2nd Quarter 20 10: The NO2 data recovery for the quarter was 92%. The NO2 average 

during the 2nd quarter was 4ppb. The highest I -hour average was 20ppb, and it occurred 

on April 8, 20 10. 

3rd Quarter 20 10: The NO2 data recovery for the quarter was 9 1 %. The NO2 average 

during the 3rd quarter was 3ppb. The highest 1-hour average was 24ppb, and it occurred 

on September 27,2010. 

4" Quarter 201 0: The NO2 data recovery is currently estimated at 90%. The NO2 

estimated average during the 4th quarter is 4.6ppb. The highest 1 -hour average was 23ppb 

and it occurred on November 30,201 0. 

In conclusion, while the Pechanga Ambient Air Monitoring Station is still in the process to 

gather 3 full years worth of data, all current data indicate the 1-Hour NO2 standard will be met. 

The Pechanga Band of Luisefio Indians respectfully recommends that the Pechanga Indian 

Reservation and the areas within its exterior boundaries be designated as 
unclassiJiable/attainment for the I -Hour NO2 National Ambient Air Quality Standard. Thank 

you for your immediate attention on this matter. 

If you have any questions regarding this recommendation or requests for additional information, 

please contact Ms. Syndi Smallwood, Pechanga Environmental Department Director,
