Re: MACT Semi-Annual Reporting for 

Period January 1, 2005 through June 30, 2005. 

Dear Mr. O’Neill, 

This report includes three separate reports as required by 40 CFR 63 Subparts A and 

NNN. The first report summarizes periods of startup, shutdown, and malfunction where 

actions taken were inconsistent with the plan in accordance with MACT requirements, 40 

CFR 63.10(d)(5) and 40 CFR 63.1386(c). The second report is the “Summary Report – 

Gaseous and Opacity Excess Emission and Continuous Monitoring System Performance” 

as required in 40 CFR 63.10(e)(3) and 40 CFR 63.1386(e). The third report is the 

“Gaseous and Opacity Excess Emission and Continuous Monitoring System Performance 

Report” as required in 40CFR63.10(e)(3) and 40CFR63.1386(e) if monitored parameters 

deviate more than 1% of the total operating time. Each report is labeled appropriately 

and is for the period January 1, 2005 through June 30, 2005. 

As the responsible official, I certify to the accuracy of this report. If you have any 

questions regarding this information, please contact our Facility Environmental Leader, 

David Krenitsky, at (518) 475-3673.

HAP’s Monitored: The Wool Fiberglass MACT focuses on two surrogate pollutants for 

control of HAP’s from the Fiberglass manufacturing process. Particulate matter is 

limited to 0.5 lb PM per ton of molten glass produced from the glass melting process and 

formaldehyde is limited to 1.2 lbs per ton of molten glass produced, during fiber forming, 

curing and cooling . 

Process Units: In general the fiberglass manufacturing process is composed of a glassmelting furnace that melts batch materials into glass. The molten glass is passed through 

a rotary spin (RS) forming process where a fine, glass fiber is produced. Binder is 

applied to the fiber as it forms a “pack” on the surface of a forming conveyor. Once 

collected, the pack passes through a curing and cooling process followed by final 

fabrication and packaging. Tables 1 and 2 define the manufacturing sources at this 

facility, including individual processes, control devices, and monitored parameters.

During the period 12/25/05 – 12/28/05, DM2 Furnace DEP #1 field (only) was out of 

operation for 81.73 hours. During this period, #2 field and #3 field were fully operational 

except on 12/27 for 4.15 hours when the furnace went to bypass. The cause of #1 field 

downtime was various electrical issues, which required a period of investigation and 

troubleshooting. The cause of the bypass was to safely gain access to the DEP to perform 

additional troubleshooting of #1 field.

Re: MACT Semi-Annual Reporting for Period January 1, 2007 through June 30, 2007 

Dear Mr. O’Neill, 

This report includes three separate reports as required by 40 CFR 63 Subparts A and 

NNN. The first report summarizes periods of startup, shutdown, and malfunction where 

actions taken were inconsistent with the plan in accordance with MACT requirements, 40 

CFR 63.10(d)(5) and 40 CFR 63.1386(c). The second report is the “Summary Report – 

Gaseous and Opacity Excess Emission and Continuous Monitoring System Performance” 

as required in 40 CFR 63.10(e)(3) and 40 CFR 63.1386(e). The third report is the 

“Gaseous and Opacity Excess Emission and Continuous Monitoring System Performance 

Report” as required in 40CFR63.10(e)(3) and 40CFR63.1386(e) if monitored parameters 

deviate more than 1% of the total operating time. Each report is labeled appropriately 

and is for the period January 1, 2007 through June 30, 2007. 

As the responsible official, I certify to the accuracy of this report. If you have any 

questions regarding this information, please contact our Facility Environmental Leader, 

David Krenitsky, at (518) 475-3673.

HAP’s Monitored: The Wool Fiberglass MACT focuses on two surrogate pollutants for 

control of HAP’s from the Fiberglass manufacturing process. Particulate matter is 

limited to 0.5 lb PM per ton of molten glass produced from the glass melting process and 

formaldehyde is limited to 1.2 lbs per ton of molten glass produced, during fiber forming, 

curing and cooling. 

Process Units: In general the fiberglass manufacturing process is composed of a glassmelting furnace that melts batch materials into glass. The molten glass is passed through 

a rotary spin (RS) forming process where a fine, glass fiber is produced. Binder is 

applied to the fiber as it forms a “pack” on the surface of a forming conveyor. Once 

collected, the pack passes through a curing and cooling process followed by final 

fabrication and packaging. Tables 1 and 2 define the manufacturing sources at this 

facility, including individual processes, control devices, and monitored parameters.

Re: MACT Semi-Annual Reporting for Period January 1, 2008 through June 30, 2008 

Dear Mr. McPherson, 

Please find attached a revised MACT Semi-Annual Report for reporting period January 1, 2008 

through June 30, 2008. 

On July 29, 2008 Owens Corning Insulating System, LLC submitted the MACT Semi-Annual 

Report for January 1, 2008 through June 30, 2008. The report included three separate reports as 

required by 40CFR63 Subparts A and NNN. 

During review of the facility data to complete the MACT Semi-Annual report for the 2nd half of 

2008, we discovered a deviation that occurred during the 1st half of 2008 reporting period that had 

not been included in this report. This deviation has been added to the second report of this 

document “Summary Report – Gaseous and Opacity Excess Emission and Continuous 

Monitoring System Performance” as required in 40CFR63.10(e)(3) and 40CFR63.1386(e).

This report includes three separate reports as required by 40 CFR 63 Subparts A and 

NNN. The first report summarizes periods of startup, shutdown, and malfunction where 

actions taken were inconsistent with the plan in accordance with MACT requirements, 40 

CFR 63.10(d)(5) and 40 CFR 63.1386(c). The second report is the “Summary Report – 

Gaseous and Opacity Excess Emission and Continuous Monitoring System Performance” 

as required in 40 CFR 63.10(e)(3) and 40 CFR 63.1386(e). The third report is the 

“Gaseous and Opacity Excess Emission and Continuous Monitoring System Performance 

Report” as required in 40CFR63.10(e)(3) and 40CFR63.1386(e) if monitored parameters 

deviate more than 1% of the total operating time. Each report is labeled appropriately 

and is for the period January 1, 2009 through June 30, 2009. 

As the responsible official, I certify to the accuracy of this report. If you have any 

questions regarding this information, please contact our Facility Environmental Leader, 

David Krenitsky, at (518) 475-3673. 

Sincerely,

Although there were startups, shutdowns and malfunctions during this reporting period, 

all actions taken were consistent with the Startup, Shutdown, and Malfunction (SSM) 

Plan. 

Report: Periods of Deviation from the Operations, Maintenance and Monitoring 

(OMM) Plan.

40 CFR 63 Subpart NNN

The following instances are being reported as a deviation of procedure outlined in the 

facility OMM Plan: 

1. Based on requirements within the OMM Plan, a density check is required at least 

once every 8 hours. There was one incident where the duration between density 

testing exceeded eight hours. 

2. Based on requirements within the OMM Plan, an LOI check is required at least 

once every 8 hours. There was one incident where the duration between LOI 

testing exceeded eight hours.

HAP’s Monitored: The Wool Fiberglass MACT focuses on two surrogate pollutants for 

control of HAP’s from the Fiberglass manufacturing process. Particulate matter is 

limited to 0.5 lb PM per ton of molten glass produced from the glass melting process and 

formaldehyde is limited to 1.2 lbs per ton of molten glass produced, during fiber forming, 

curing and cooling. 

Process Units: In general the fiberglass manufacturing process is composed of a glassmelting furnace that melts batch materials into glass. The molten glass is passed through 

a rotary spin (RS) forming process where a fine, glass fiber is produced. Binder is 

applied to the fiber as it forms a “pack” on the surface of a forming conveyor. Once 

collected, the pack passes through a curing and cooling process followed by final 

fabrication and packaging. Tables 1 and 2 define the manufacturing sources at this 

facility, including individual processes, control devices, and monitored parameters.
