### 31 May 2011 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 accuratefor 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,
