Subject: Information Request - Wool Fiberglass

Attachments: Wool Fiberglass Modeling Sources by Co. 5.18.11.xls; FTP Instuctions.doc

Angus,

Attached are two files; one is for directions to the FTP site that contains the aerial views of all the Wool 

Fiberglass facilities (divided by company), the other, is an excel spreadsheet of each Wool Fiberglass 

source with what we understood (from process flow diagrams and other ICR info) to be each source’s 

control device, stack configuration, and stack parameters. There are several facility responses where 

we had difficulty understanding whether emission sources were routed together to one stack or 

divided into separate stacks. This is important for us to know in order to determine how to model 

emissions correctly. Each row in the spreadsheet is essentially a “stack” associated with an emission 

source. For example, if for a particular row the source is listed as “forming, curing, cooling” we 

understood those three sources to be routed together to one stack. If forming, curing, and cooling are 

listed in separate rows we have concluded that these sources are routed to separate stacks. We need 

the facilities to check that our interpretation of the configuration is correct, as well as, the stack 

parameters corresponding to the source (columns F-I). If they are not correct, please have facilities 

correct the spreadsheet. We also need each facility to do the following:

 Confirm the control device listed in Column F. If there is more than 1 control device please 

have the facility list each control device in order (i.e. Furnace-> Baghouse ->Thermal 

Incinerator-> Stack).

 Confirm or fill in the Stack IDs in Column J and mark/label them on the aerial view jpg. We 

are only interested in stacks associated with furnaces and FCC processes. Facilities do not 

need to label or mark stacks associated with other processes. You can send the aerial views 

directly to us, you do not have to post them to the FTP site. 

Also, the following facilities have not sent Process Flow Diagrams:

 Guardian: Albion, Inwood, Kingman, Mineral Wells, and Winnsboro. Also, we cannot “find” 

the Winnsboro plant as the address and coordinates they sent are in the middle of a city 

with many buildings. It is difficult to tell which one is the plant. Please send an aerial view of 

the Winnsboro plant

 CertainTeed: Athens (the file extension did not work)
There are a few other questions we have for Wool Fiberglass Facilities: 

 Knauf listed several sources as “idle” -- we need to know if these are temporarily or 

permanently out of commission. 

 Any recent changes in binder formulations and a list of facilities that have switched to a non 

formaldehyde binder.

 Elaborate on the “collection” process for Wool Fiberglass. Is it different than for Mineral 

Wool? Is it part of Forming?

 Are there significant HAP emissions coming from Cooling? 

 What can facilities provide in order for us to calculate an Acute Factor (equipment 

limitations, variability in binder and product formulations, certification codes or standards 

product must meet, formaldehyde contents, etc.)
