The CDC Wonder Environmental Data uses a different modeling approach than EPHT to estimate air quality. It may be useful to compare these estimates to the EPHT estimates. In addition, it may be useful to contact air quality experts in your state who may have more detailed information regarding differences in air quality within counties. For communities with air monitors located in them, the EPA maintains an AirData website that provides more current information on not only fine particulate matter, but also other types of air pollution.
