Joe,

Sorry for not getting to this on Friday as we discussed on Thursday.  It was well after 6:00 pm on Friday by the time I

finally wrapped up the 2013 emissions inventory submittal and I was spent.

The answers to your questions are below.  See update to question 2 response.

Question 1: Current business conditions did not justify an Oxy‐fuel furnace on line 4‐2 similar to line 4‐1.

Question 2: PPG expects emissions to be within permitted allowable emissions for both furnaces.  Copies of permitting

documentation from the TCEQ Novell Webpublisher https://webmail.tceq.state.tx.us/gw/webpub are attached to this

email (search for PPG 898 & click to search all 3 libraries).  The line 4‐2 cold repair project is TCEQ project 178473. The

most recent copy of the MAERT, from project 189540 is attached.  The project will conserve fuel.

Question 3: PPG Wichita Falls glass furnaces normally run on natural gas.  One or both of the furnaces burned some oil

as a back‐up fuel for short periods several years ago.  No emissions data exists for oil firing.

Hi Dan,

Thanks for talking to me this afternoon.  By way of background, we are in the middle of configuring modeling runs to

assist us in our evaluation of the Texas Regional Haze SIP.  Because of the Wichita PPG plant’s close proximity to the

Wichita Mountains Class I area in Oklahoma, we are including its emissions in our modeling.  Consequently, I’d like to be

as accurate as I can in the emissions we assign to it.  Would you please answer the following:

1. You mentioned that you were not planning on installing the same type of oxy fuel system on line 2 as was

installed on line 1, however, there would be some NOx reductions on line 2.  Would you please describe why

you are not planning on installing the oxy fuel system, and how you are going to achieve NOx reductions in the

line 2 furnace?

2. Would you provide me with NOx, SO2, and PM emissions estimates in tons/year for line 1 and what you expect

for line 2 when it comes back on line?  You mentioned you can point me to the TCEQ’s website?  Would you

please send me the permits for line 1 and line 2?

3. How frequently do you burn fuel oil and in what quantities?  To what extent does this impact your SO2

emissions?

Thanks.  Please feel free to call me at 214‐665‐7186 if you have any questions.
