I think a parenthetical is fine

– something along the lines of “assuming a 25% to 50% compliance

margin.”

Hello Cortney

This is not a new requirement

- it's just an assumption of how the plants operate. We were trying to add

additional discussion on how the PM CEMS is problematic since facilities operate at even lower levels

than the actual limit, thereby having even more issues with using the PM CEMS. So, are you saying you

would prefer we put this in parentheses, or do you want to have the call today to discuss?

In addition, to stay in compliance, sources would be required to operate at average levels of .02 to .03

lb/ton clinker, w hich equates to 3 to 5 mg/dscm.

Sharon

– to c larify, the inserted text is highlighting the point that in order to comply with the prior

standard of 0.04, sources would need to on average be at 0.02 to 0.03? It might be helpful to add a

parenthetical explaining the compliance margin assumption.

Thank s,

Cortney

HI Sharon,

This seems like a new requirement

– can we have a conversation tomorrow (I’m free from 10

- 2 and 3

- 5)

to talk a bout the insert on page 47 :

In addition, to stay in compliance, sources would be required to operate at average levels of .02 to .03

lb/ton clinker, which equates to 3 to 5 mg/dscm.

Thanks,
