Jeff

Attached is the updated list of modeling data. We have only been able to fill in a few more facilities, including the missing Boral plants. For all others, we recommend using the attached default values. These are based on the average values of all availab le data for the stack height, stack diameter (assuming circular, tho we do have some square stacks), stack exit temperature, and acfm air flow. Velocity can be calculated from these parameters. We believe these average values, used in combination with ea ch other, represent a reasonably conservative approach to establishing default values. We have provided figures that show the maximum, minimum, average, and median for each parameter in four different kiln (size) groupings. We will be looking at modeling all plants using HEM3, as you are. Once we are both done, it will be interesting to discuss our conclusions. Obviously, a huge factor in this modeling will be the emission rates used in the model when site

- specific information is not available (as is the c ase for many/most facilities for Cl2). We are working on our assumptions and seeing whether there is any correlation between Cl2 emissions and other emissions (presumably HCl). We appreciate your willingness to consider this approach for our industry. We continue to believe that our facilities do not emit dangerous amounts of HAP and should not be forced out of business with unreasonable controls that have limited to no environmental benefit.
