Notes/Questions

Stack combined with Furnace 1901 (Continuous 

filiment fiber). 1902 only makes glass marbles. 

Marbles can be used to make fiberglass in a separate 

unit(s) in Cleburne or other locations.

Both melters exhaust from a single stack.

Not an emissions point. Emissions are listed in Line 91 

collection below. Forming and collection are 

combined.

Oven and Cooling Emissions in same stack.

4 stacks - lets model as 1. 

Not an emissions point. Emissions are listed in Line 92 

collection below.

Not an emissions point. Emissions are listed in Line 93 

collection below.

There are 4 forming /collection stacks.

There is a single exhaust for both ovens.

Duplicate of above 92 and 93 forming collection (Row 

9). Remove.

No cooling on Lines 92 or 93. Remove.

 

2 furnaces controlled by ESP followed by baghouse. 

Furnaces produce marbles only. Marbles are used to 

make fiberglass in a separate unit(s) in Defiance or 

other locations.

Melters 1, 2, and 3 have a common stack

Common stack for 2 dust collectors (4 and 5)
Common stack for 3 dust collectors (4, 5, & 6)

There are 4 stacks. 2 for each module. 2 Modules.

There are 2 stacks for the cooling emissions.

Common control for 3 glass melters E17-E19

All oven emissions go to 1 stack, PT-4. There is only 

one oven.

All emissions go to PT-4, not a source.

Each forming/collection module has one stack.

PFD looks different than to what was put in ICR. Mist 

eliminated added after PFD drawn.

In series after the scrubber on Line 2. Not a 

separate source, emissions are all included on Line 

2 (Row 63).

Controls for rotary lines 1, 2, 3, and/or 4

Gas assist on melters for startup only; all have 

common ducting to 3 parallel scrubbers with 3 parallel 
All 28 units feed to a common plenum with parallel 

control devices (fabric filters) and 7 stacks. 

(3 additional scrubbers listed as back-up controls -- did 

not include here)

Curing and cooling are merged into EP30.

No baghouse on forming/collection. 

Are all stacks the same height and diameter. On ICR 

some have 7ft diameter and some have 1.85? All 

seven stacks have same stack parameters and have 

been corrected. 

All 28 units feed to a common plenum with parallel
