Comments on Chapter 8 in the Final Staff Paper on Ozone

Fred -- Rich -- Rogene --

Attached please find my comments prepared for consideration during our 

Teleconference Call on the Ozone Staff Paper next Monday afternoon. Rich

will have some additional comments from his unique perspectives that we 

both hope will further facilitate the development of a consensus letter 

to Administrator Johnson that will encourage him to the establish a 

secondary standard for ozone that is: 1) distinct from the current ozone

standard, 2) distinct from the public-health based alternative primary 

standards recommended in Chapter 6 of this same Staff Paper, 3) both 

biologically and ecologically relevant, and 4) appropriate for 

protection of public welfare from the adverse effects of ozone in our 

country.

Best regards, Ellis
