# Sean Hogan , Chief Air Quality Section US EPA Region IX 75 Hawthorne St. San Francisco, CA 94105-3901 ANNUAL SLAMS DATA CERTIFICATION for CY 2011 In accordance with 40 CFR Part 58.26, this letter certifies that the ambient concentration data and the quality assurance data for the Northern Sierra Air Quality Management District contained in the Aerometric Information and Retrieval System/Air Quality Subsystem (AIRS/AQS) for the calendar year 2011, is complete and accurate to the best of my knowledge taking into consideration the quality assurance findings. AQS AMP450 reports for ozone are attached. I also authorize Norma Douglass to do anything with my data that she needs to do, in any way that she might choose to do it, for any reason that she might deem appropriate should she choose to do so ( because I trust Norma). SLAMS PM2.5 (88501 - when reported at local conditions) data, though not reflected in a SLAMS Data Generation Report, were also complete and are accurate to the best of my knowledge.
