PART 1.0 FACILITY DESCRIPTION 

1.1 Site Determination 

There are no other facilities which could possibly be contiguous or adjacent and under common 

control. 

1.2 Previous and/or Other Names 

Owens Corning Fiberglas Corporation 

Owens Corning – Fairburn Plant 

1.3 Overall Facility Process Description 

Raw Material Handling and Batch Charging 

Raw materials including sand, cullet, and other compounds are delivered to the plant by trucks and 

rail cars. The raw material delivery and handling system includes an unloading grate; batch house 

storage bins; and batch transfer, weighing, and mixing equipment. Raw materials are fed from the 

batch charging operations to the FG-1, FG-2, and FG-3 electric glass melting furnaces (FG11, FG21, 

and FG31). 

Particulate matter (PM) is emitted during raw material handling and batch charging. 

Electric Cold Top Furnaces 

There are three cold top electric furnaces (FG11, FG21, and FG31) which supply thermal energy to 

the mixed glass batch via resistive heating from under glass electrodes. Each furnace is equipped 

with natural gas /propane backup burners, which are utilized only during startup periods or extended 

power losses to maintain the furnace operating temperature. Fiberglass production is halted during 

such periods. 

PM, PM10, PM2.5, Sulfur dioxide (SO2), Volatile Organic Compound (VOC), Carbon monoxide

(CO), and Nitrogen oxides (NOx) are emitted from the cold furnaces 

Risers/Channels and Forehearths 

The molten glass exiting each furnace flows via gravity through a conditioning riser/channel (FG12, 

FG22, FG32) into the forehearth (FG23, FG23, FG33). The forehearth then delivers the molten glass 

to the forming section. The FG-1 and FG-3 Riser/Channel and Forehearths (FG12, FG32, FG13, 

FG33) are heated with natural gas. The FG-2 Riser/Channel and Forehearth utilize an enclosed 

Riser/Channel and Forehearth (FG22 and FG23) that does not generally require natural gas for 

heating. 

PM, PM10, PM2.5, SO2, VOC, CO, and NOx are emitted from the risers/channels, and the forehearths.

Forming Sections 

In the forming sections (FG14, FG24, FG34) molten glass in spinners cause streams of molten glass 

to go into a space where air is blowing down the molten glass to form a downward flowing veil of 

glass fibers. The veil is first sprayed with water for cooling, and then coated with a 

phenol/formaldehyde resin-based binder solution. The coated fibers are collected and formed into a 

pack on a horizontal conveyor. 

Each manufacturing line is equipped with a dropout box system located below the forming conveyors 

to collect fibers that pass through the forming chain. Each dropout box system (G1S, G2S, G3s) 

contains a proprietary non-traditional scrubbing system that serves to remove fiber entrained in the 

forming section exhaust. The fibers collected in the dropout box system are generally larger than 10 

microns. Exhaust from the dropout box is combined with exhaust from the curing section incinerator 

in the respective mixing chamber for each manufacturing line before being emitted to the 

atmosphere. 

PM, PM10, PM2.5, SO2, VOC (formaldehyde, phenol, methanol), CO, NOx, and ammonia are emitted 

from the forming sections. 

Curing Sections 

After forming, the fiberglass pack enters its curing oven (FG15, FG25, FG35). A curing oven is 

comprised of zones that drive combustion air either upwards or downwards through the pack to drive 

off water and thermally cure the binder. Emissions from each curing oven is controlled by a Thermal 

Incinerator (G1I, G2I, G3I). As indicated above, exhaust from the curing section incinerator is 

combined with exhaust from the forming section in the respective mixing chambers for each 

manufacturing line before being emitted to the atmosphere. 

PM, PM10, PM2.5, SO2, VOC (formaldehyde, phenol, methanol), CO, NOx, and ammonia are emitted 

from the curing sections. 

Cooling Sections 

The cured pack enters the Cooling Section (FG16, FG26, FG36) where air is drawn through the pack 

to cool it. The FG-1 Cooling Section is equipped with an aerofilter (G1A) that aids in the removal of 

large particles (diameter greater than 10 microns) from the air exhaust. The FG-2 Cooling Section is 

equipped with an aerofilter (G2A) and a smoke stripper (G2SS) that aid in the removal of PM from 

the exhaust air, while the FG-3 Cooling Section is equipped with a Venturi Scrubber (G3W) that aids 

in the removal of PM from the air exhaust. 

PM, PM10, PM2.5, SO2, and VOC (formaldehyde, phenol, methanol) are emitted from the cooling 

sections.

Final Finishing 

After cooling, the fiberglass product is trimmed to set the final width and cut to length. Various 

products made on FG-1 or FG-2 require the addition of a vapor barrier facing. This facing is 

generally Kraft paper or foil, and is bonded to one side of the fiberglass product with an asphaltbased adhesive in the asphalt application process (FG18 or FG28). A flexographic printing press 

(FG17 or FG27) then applies the Owens Corning Insulating Systems (OCIS) logo and product 

information to the outward side of the product facing. Not all products made on the FG-1 or FG-2 

requires the addition of facing material. Such products are marked directly on the fiberglass product 

with one of two inkjet printers. The marked products are then compressed and packaged in bags or 

rolled up. 

PM10 and VOC are emitted from the finishing sections.

change and shall include a brief description of the change within the Permitted 

facility, the date on which the change is proposed to occur, any change in emissions, 

and any Permit term or condition that is no longer applicable as a result of the change.

existing Permit term or condition. 

b. The Permittee must provide contemporaneous written notice to the Division and to 

the EPA of each such change, except for changes that qualify as insignificant under 

Rule 391-3-1-.03(10)(g). Such written notice shall describe each such change, 

including the date, any change in emissions, pollutants emitted, and any applicable 

requirement that would apply as a result of the change. 

c. The change shall not qualify for the Permit shield in Condition 8.16.1. 

d. The Permittee shall keep a record describing changes made at the source that result in 

emissions of a regulated air pollutant subject to an applicable requirement, but not

remaining Permit term is one (1) year or longer. In this case, the reopening shall be 

completed no later than eighteen (18) months after promulgation of the applicable 

requirement. A reopening shall not be required if compliance with the applicable 

requirement is not required until after the date on which the Permit is due to expire;

statements were made in establishing the emissions standards or other terms or 

conditions of the Permit; or 

[391-3-1-.03(10)(e)6(i)(III) and 40 CFR 70.7(f)(1)(iii)]

8.13 Excess Emissions Due to an Emergency 

8.13.1 An “emergency” means any situation arising from sudden and reasonably unforeseeable 

events beyond the control of the source, including acts of God, which situation requires 

immediate corrective action to restore normal operation, and that causes the source to 

exceed a technology-based emission limitation under the Permit, due to unavoidable 

increases in emissions attributable to the emergency. An emergency shall not include 

noncompliance to the extent caused by improperly designed equipment, lack of 

preventative maintenance, careless or improper operation, or operator error.

8.13.2 An emergency shall constitute an affirmative defense to an action brought for 

noncompliance with the technology-based emission limitations if the Permittee 

demonstrates, through properly signed contemporaneous operating logs or other relevant 

evidence, that:

emergency to the Division within two (2) working days of the time when emission 

limitations were exceeded due to the emergency. This notice must contain a 

description of the emergency, any steps taken to mitigate emissions, and corrective 

actions taken. 

8.13.3 In an enforcement proceeding, the Permittee seeking to establish the occurrence of an 

emergency shall have the burden of proof. 

[391-3-1-.03(10)(d)7 and 40 CFR 70.6(g)(4)] 

8.13.4 The emergency conditions listed above are in addition to any emergency or upset 

provisions contained in any applicable requirement.
