Good afternoon Laura

I promised you I will share with you on our universe of available test data for the three Felman furnaces,

which we will then use to estimate the baseline stack emissions. My contractor at EC/R has completed

this task, and the file is attached.

First, about the “significant concerns about the ICR data” that Felman has raised “from the beginning”, I

assume you are referring to the Furnace #2 2010 ICR data. We do not know what your concerns are. We

also do not have any documentation about this concern until last Friday. If Felman can provide the

documentation to us, I would appreciate it.

For Furnace #2, we have a total of 2 test data, with tests conducted in 2009 and 2010 respectively. Inreviewing the 2010 Furnace #2 ICR data, we noticed the average particulate emission was 4.65 lb/hr.

This is almost two times higher than the 2009 tests at 2.06 lb/hr. However, the 2010 test had an average

grain loading of 0.001, and this emission concentration is similar to the other two furnaces. Without morespecifics on your concerns, we intend to average the two tests in calculating the stack emissions for

Furnace #2.

We also have three tests for Furnace #5 (10/2007, 11/2008, and 11/2009). For Furnace #7, we have three

tests as well (1 0/2007, 11/2008, and 11/2009). The October 2007 test for Furnace #7 had unusually highemissions(134 lb/hr). We concluded this test data is invalid, and will not include this test in our database.We intend to average all the valid tests for the two furnaces.

We also have test summaries for Furnaces #5 and 7 tested in November, 2010. The test summaries were

provided by WV DEP. We have been discussing with the WV colleagues on the test results. We think

there might have been some mix-up on the air flow calculations. If we are able to correct the calculations,

we will include the November 2010 tests. Otherwise, we will exclude them.

In summary, we are planning the project activities based on the assumption of a December promulgation

deadline. Unless you can provide the details on why the 2010 ICR test is invalid by this Thursday, we will

include it in our database.

Thank you and best regards,
