Keith: 

I have spoken with our corporate director of process/environment and he 

has 

confirmed that the Ravena kilns do not have an alkali bypass. Alkalis 

are 

removed by wasting dust from the ESPs. 

Sorry for the confusion in the worksheet. Please make the necessary 

corrections. 

I'll see you next week.

Dear Mike: 

This is a follow up to my voice mail. 

Attached is the Part 1 questionnaire response for Ravena. 

In item 10 it states that the long wet kilns at Ravena have an alkali 

bypass. My understanding was that alkali bypasses were only used on 

preheater or preheater/precalciner kilns. I called the contact listed on 

the form, John Regan, and left a message. He responded that there are no 

alkali bypasses at his facility Unfortunately he just left on vacation. 

The form shows an actual gas percentage, so is there some other type of 

bypass?
