Steve,

Attached are the emails where you provided the test data and your response when we asked whether or not the two collection chamber

results should be added or averaged.

Methanol and Phenol UPLs were based solely on the data you provided in the email below. The data points used to come up with the

UPL (proposed limit) were calculated the same way for Methanol and Phenol. Below is an example of how we calculated the data points

used for the Methanol UPL based on your numbers.

Methanol for Vertical collection and curing:

Data point 1 =0.0118+sum(0.2448+0.365)

= 0.622

Data point 2 =0.0113+sum(0.2448+0.365)

= 0.621

Data Point 3 -0.0127+sum(0.2448+0.365) =0.623

These three numbers were plugged into our UPL calculations to come up with the proposed limit of 0.63. The reason the UPL isn’t much

different than the average of the data points is because the three data points used were practically identical, and thus did not have much

variability. The same is true of Phenol and Formaldehyde.

Formaldehyde was calculated in a similar manner but using the data from the test report.

If you have any questions on this please feel free to call me at 919.541.6623.

Thanks,

I would say that the sum of the numbers is the correct method for determining total emissions. We have two fans connected to the

collection chamber. These fans duct the exhaust to the screen house.

Subject: Thermafiber Stack Test Data (Non-CBI)

Cindy

– As we discussed, Thermafiber recently inquired from our stack testing firm whether or not they had the FTIR data from tests

performed in 2008 and if they could reassess the phenol and methanol levels within the data. They did. A draft of the introduction and

test summary is attached. Regarding the control efficiency of the filter on the collection chamber (blow chamber), I do not have an

estimate. I suspect that the organics may pass through since the filter is really meant for particulate control. You also asked for each of

the data points that were averaged to obtain the numbers shown in the summary. They are as follows:

RTO Outlet

– Methanol

– 0.0118, 0.0113, 0.0127 lb/ton melt

RTO Outlet

– Phenol

– 0.0363, 0.0367, 0.0402 lb/ton melt

Collection Duct 1

– Methanol

– 0.248 lb/ton melt

Collection Duct 2

– Methanol

– 0.365 lb/ton melt

Collection Duct 1

– Phenol

– 0.184 lb/ton melt

Collection Duct 2

– Phenol

– 0.276 lb/ton melt

(For the collection ducts, there was only a 60 minute test for each duct. Three data points were not measured.)

Let me know if you have questions. I will submit the whole report (even though it is labeled as DRAFT) as CBI to EPA’s Robert Morales.
