Jared Blumenfeld

Regional AdministratorEPA 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 Aerometric (J) Information and Retrieval System (AIRS) as ofJune 1, 2010 are accurate for the calendar year 2009, to the best of my knowledge. A SLAMS summary report generated by AIRS would,

therefore, depict accurate summary statistics for 2009. Both precision and accuracy data for all

GBUAPCD monitoring of criteria pollutants in 2009 have also been submitted to AQS.

Copies ofthe AQS Quick Look Criteria Parameters Report (AMP45O) and the Data Quality

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

Sincerely,

Theodore D. Schade

Air Pollution Control Officer
