John,

Do you really want the annual 4th high concentrations, or do you actually want the Design Values based on the 

form of the standard, which are the running 3-year averages of the annual 4th high concentrations?

Thanks,

Hi Carl -

Would it be possible for you to modify Figure 4-1 by adding the 4th high ozone 

concentrations from 2002-2012 at your high conc monitor (i.e., Alpine)? You could have 

ozone values on the right side of the graph. 

Thanks
