Subject: PTPC Submittal of Corrections to P&P RTR Modeling Input Data

Bill-

Here is the information you and I discussed on Monday. My understanding
is that since the docket is closed for direct submittal, that you will
be sure to include this data in the record of the docket. Thank you.

Attached is the report by Trinity Consultants summarizing the reasons
for the submittal of the revised data for the Port Townsend Paper Mill.
The excel revision sheet is also attached. We have highlighted the
revisions in yellow. 

We believe that risk evaluations should be done with the most accurate
information available. We have had Trinity simulate the modeling using
the HEM3 version. This work demonstrates that the original MIRs for the
mill are overstated. We would encourage EPA to consider rerunning the
model you are presently using incorporating these revisions. 

I appreciate your willingness to accept this data. Let me know if you
have any questions or need any more information.

Sincerely-

Eveleen Muehlethaler
