O3 NAAQS RIA "Bins" from baseline conversation

 

Ron and Lydia,

 

Attached is a table that represents the "bins" that we described in the
conversation this morning on O3 NAAQS Baseline.  You'll notice that the
table not only includes bin definitions, but also columns for estimates
that are derived from air qual modeling separate from estimates that are
not derived from air quality modeling.

 

I am happy to answer any questions you might have; please don't hesitate
to call me for clarification  (202) 395-4551

 

Best regards,

 

heidi
