Chuck,

I am attaching a spreadsheet which contains all the raw data that went into the

industry's analysis in order to arrive at emissions estimates for each of the

three mines that were tested. To the extent that EPA needs to analyze or review

the industry's analysis, all of the necessary inputs are included in the

attached.

We are still working on the QA/QC process and it is possible that some of these

numbers may change slightly. We do not anticipate that any such changes would

result in a noticeable change to the emissions estimates.

Our goal is to get you a more complete "report" some time next week.

This report will include all the field data sheets and other backup information.

I hope that this satisfies the needs of your management for the time being. Feel

free to give me a call with any questions.
