Jared Blumenfeld 

Regional Administrator 

EPA Region 9 

75 Hawthorne Street 

San Francisco, CA 94105 

In accordance with 40 CFR Part 58.26, this letter certifies that the ambient air monitoring data for 

the Great Basin Unified Air Pollution Control District (GBUAPCD) contained in the EPA Air 

Quality System (AQS) as of May 31, 2011 are accurate for the calendar year 2010, to the best of my 

knowledge. A SLAMS summary report generated by AQS would, therefore, depict accurate 

summary statistics for 2010. Both precision and accuracy data for all GBUAPCD monitoring of 

criteria pollutants in 2010 have also been submitted to AQS. 

Copies of the AQS Quick Look Criteria Parameters Report (AMP450) and the Data Quality 

Indicator Report (AMP255) have been enclosed along with accompanying electronic copies as 

requested. 

Sincerely, 

Theodore D. Schade 

Air Pollution Control Officer
