Dear Mr. Clover: 

The Antelope Valley Air Quality Management District (AVAQMD) is responsible for submitting local air 

quality data to the Air Quality System (AQS). In addition, AVAQMD submits precision data for the 

mentioned air quality data. The Air Resources Board (ARB) submits quality assurance data for the 

AQMD which is under the Primary Quality Assurance Organization. In accordance with Title 40, Code of 

Federal Regulations (CFR), Part 58.15, this letter certifies that the 2013 ambient air quality data and 

precision data for which the AVAQMD has certification authority at AQS are completely submitted and 

accurate to the best of my knowledge, taking in consideration the quality assurance findings. Data 

validation and assessment are continuing functions and may result in future corrections to this data. In 

addition, this letter also certifies previously certified data that has subsequently been modified. 

Along with this letter, I am submitting the Data Certification (AMP600) and Quicklook All Parameters 

(AMP450NC) reports, as required by the CFR. 

If you have questions regarding the ambient air quality data portion and/or the precision data portion of 

this letter, please contact Mr. Christopher A. Collins, Supervisor of the Air Monitoring Department at 

760-245-1661 ext. 6282 or by e-mail at: ccollinsgPmdaqmd.ca.gov For questions regarding the annualaudits portion of this letter, please contact Mr. Ranjit Bhullar, Manager of the Quality Assurance Section 

at ARB's Monitoring and Laboratory Division, at (916) 322-0223 or by e-mail at: mbhullar@arb.ca.gov 

Sincerely, 

Christopher A. Collins
