Permit Issued To:OWENS CORNING INSULATING SYSTEMS LLC 1 OWENS CORNING PKWY TOLEDO, OH 43659
Facility: OWENS-CORNING INSULATING SYSTEMS- FEURA BUSH 1277 FEURA BUSH RD FEURA BUSH, NY 12067
Contact: DAVID A KRENITSKY OWENS-CORNING DELMAR PLANT 1277 FEURA BUSH RD FEURA BUSH, NY 12067 (518) 475-3673 Description: The Owens Corning Insulating Systems, LLC facility in Feura Bush, New York (OCIS Delmar Plant) manufactures wool fiberglass insulation products through the operation of two glass furnaces and associated pr oduction lines (DM1 and DM2) along with air pollution control equipment. The facility currently operates under a Title V permit pursuant to Article 19 (Air Pollution Control) of the New York State Environmental Conservation Law and Title V of the federal Clean Air Act. This modification to the Title V permit establishes emission limits (caps) so that the facility may avoid applicability of Best Available Retrofit Technology (BART) requirements under 6 NYCRR Part 249. By incorporating these emission caps, the combined potential emissions from all BART-eligible units are restricted to less than 250 tons per year of each visibility impairing pollutant; i.e., nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter less than 10 microns in diameter (PM-10). As a result, the facility is not subject to BART under Part 249. These emission caps apply to emission units U-00002, U-00003, U-00012, U-00013, andFacility DEC ID: 4012200004

DEC Permit Conditions Renewal 1/Mod 4/DRAFT Page 2 U-00014 which pertain to the glass furnaces and associated forming, curing, cooling, and smoke stripper sections of the two wool fiberglass insulation manufacturing lines. In addition, this permit modification incorporates conditions in order for the faci lity to comply with the NOx Reasonably Available Control Technology (RACT) requirements for glass plants under 6 NYCRR Subpart 220-2. The existing furn ace oxy-fuel firing control technology is already considered to be NOx RACT for each of the glass melting furnaces at the facility. However, Subpart 220-2 also requires each glass furnace at the facility to meet a facility specific NOx emission limit in pounds of NOx per ton of glass pulled and requires the installation of a continuous emissions monitoring system (CEMS) to demonstrate compliance with such emission limit. This permit modification sets forth the NOx emission limit and CEMS requirements for the glass furnaces. Furthermore, the permit has been modified to remove existing conditions pertaining to 40 CFR Part 63, Subpart NNN which is the National Emission Standards for H azardous Air Pollutants (NESHAP) for Wool Fiberglass Manufacturing. The most recent renewal and modification to the Title V permit on November 5, 2010 allowed the facility to convert its operations from a phenol-formaldehyde based binder to a non-phenol, non-formaldehyde starch-based binder system. With the completion of this binder system conversion in February 2011 for the DM1 production line and in September 2011 for the DM2 production line, the facility no longer uses phenol and formaldehyde binders. Therefore, consistent with a determination by the United States Environmental Protection Agency (USEPA) that the facility would no longer meet the definition of an affected facility under Subpart NNN upon completion of the starch-based binder system conversion, the facility is no longer subject to the Subpart NNN NESHAP requirements. Other minor changes have been made to the permit for clarity and consistency purposes.

By acceptance of this permit, the permittee agrees that the permit is contingent upon strict compliance with the ECL, all applicable regulations, the General Conditions specified and any Special Conditions included as part of this permit.

Such emission factors will be used for determining the maximum binder solids application rate (tons of binder solids applied per year) necessary to maintain emissions to less than the VOC emissions limit for the binder change project as set forth elsewhere in this permit. An acceptable VOC testing protocol must be submitted to the department at least thirty (30) days prior to conducting such testing. Testing/analysis results must be reported to the department within sixty (60) days following the completion of the testing. The testing results must also be included in the semi-annual reporting and annual compliance certification required in this permit. While submission of an acceptable testing protocol is required as explained above, the facility anticipates using the following method for the testing of VOC emissions from the new starch-based binder formulation: The method consists of a Method 5E (or equivalent) sampling train configured for total organic carbon (TOC) analysis of the back half, combined with a Method 25A (or equivalent) analyzer on a portion of the airstream exiting the Method 5E impinger train. The 0.1 N NaOH impinger contents of the Method 5E train can be analyzed for TOC, following the protocol described in Method 5E. In addition, a portion of the impinger catch can be analyzed using methods such as GasPermit ID: 4-0122-00004/00039 Facility DEC ID: 4012200004

Air Pollution Control Permit Conditions Renewal 1/Mod 4/Changes Only Page 21 DRAFT Chromatography with Flame Ionization Detection (GC-FID) where analytes are known. A portion of the 0.1 N NaOH impinger catch can also be extracted and analyzed by Gas Chromatography-Mass Spectrometry to permit identification of compounds, similar to EPA Method 8270, a water method for determining semi-volatiles. Finally, ion chromatography can be applied to the impinger catch to separate analytes such as formic acid and acetic acid. Other techniques are possible, depending upon the nature of the analytes. Polar and semi-volatile compounds will be collected by the 0.1 N NaOH impinger train. These analysis tools will establish a typical mass to carbon ratio. Once a typical mass to carbon ratio for the Method 5E catch is established, it will be used to apply to the Method 5E results when future VOC testing is required. Results will be stated as lb/hr VOC. Non-polar compounds, such as light hydrocarbons will not be collected, and they will be measured by the Method 25A FID train. The Method 25A FID train will be calibrated as propane and the results specified as lb/hr VOC. Corrections for methane or ethane will be made before the results are specified. Total VOC emissions will be the sum of the Method 5E results and the Method 25A results specified as lb/hr VOC. The following calculation will be used for the scaling factor determination of the hourly VOC rate: Given the following: - Molecular weight of each known compound - Number of carbons in each known compound - Mass of each compound 1) Calculate the mass of carbon contributed by each compound 2) Sum up the total mass of carbon 3) Calculate the percentage (%) of total mass contributed by each compound 4) Calculate the carbon to mass ratio for each compound (scaling factor for that individual compound) 5) Calculate the contribution to the scaling factor of each compound by multiplying the individual mass to carbon ratio by its percentage (%) of the total mass 6) Sum up all the individual contributions to obtain the scaling factor for the mix

Such emission factors will be used for determining the maximum binder solids application rate (tons of binder solids applied per year) necessary to maintain emissions to less than the VOC emissions limit for the binder change project as set forth elsewhere in this permit. An acceptable VOC testing protocol must be submitted to the department at least thirty (30) days prior to conducting such testing. Testing/analysis results must be reported to the department within thirty (30) days following the completion of the testing. The testing results must also be included in the semi-annual reporting and annual compliance certification required in this permit. While submission of an acceptable testing protocol is required as explained above, the facility anticipates using the following method for the testing of VOC emissions from the new starch-based binder formulation: The method consists of a Method 5E (or equivalent) sampling train configured for total organic carbon (TOC) analysis of the back half, combined with a Method 25A (or equivalent) analyzer on a portion of the airstream exiting the Method 5E impinger train. The 0.1 N NaOH impinger contents of the Method 5E train can be analyzed for TOC, following the protocol describedPermit ID: 4-0122-00004/00039 Facility DEC ID: 4012200004

Air Pollution Control Permit Conditions Renewal 1/Mod 4/Changes Only Page 29 DRAFT in Method 5E. In addition, a portion of the impinger catch can be analyzed using methods such as Gas Chromatography with Flame Ionization Detection (GC-FID) where analytes are known. A portion of the 0.1 N NaOH impinger catch can also be extracted and analyzed by Gas Chromatography-Mass Spectrometry to permit identification of compounds, similar to EPA Method 8270, a water method for determining semi-volatiles. Finally, ion chromatography can be applied to the impinger catch to separate analytes such as formic acid and acetic acid. Other techniques are possible, depending upon the nature of the analytes. Polar and semi-volatile compounds will be collected by the 0.1 N NaOH impinger train. These analysis tools will establish a typical mass to carbon ratio. Once a typical mass to carbon ratio for the Method 5E catch is established, it will be used to apply to the Method 5E results when future VOC testing is required. Results will be stated as lb/hr VOC. Non-polar compounds, such as light hydrocarbons will not be collected, and they will be measured by the Method 25A FID train. The Method 25A FID train will be calibrated as propane and the results specified as lb/hr VOC. Corrections for methane or ethane will be made before the results are specified.
Total VOC emissions will be the sum of the Method 5E results and the Method 25A results specified as lb/hr VOC. The following calculation will be used for the scaling factor determination of the hourly VOC rate: Given the following: - Molecular weight of each known compound - Number of carbons in each known compound - Mass of each compound 1) Calculate the mass of carbon contributed by each compound 2) Sum up the total mass of carbon 3) Calculate the percentage (%) of total mass contributed by each compound 4) Calculate the carbon to mass ratio for each compound (scaling factor for that individual compound) 5) Calculate the contribution to the scaling factor of each compound by multiplying the individual mass to carbon ratio by its percentage (%) of the total mass 6) Sum up all the individual contributions to obtain the scaling factor for the mixPermit ID: 4-0122-00004/00039 Facility DEC ID: 4012200004

Condition 4-10: 40 CFR 63, Subpart NNN - non-applicability Effective for entire length of Permit Applicable Federal Requirement:40CFR 63, Subpart NNN

Item 4-10.1: This section contains a summary of those requirements that have been specifically identified as being not applicable to this facility and/or emission units, emission points, processes and/or emission sources within this facility. The summary also includes a justification for classifying any such requirements as non-applicable. 40 CFR 63.1380, Subpart NNN - non-applicability to starch-based binder conversion: As part of its application submitted to the Department on December 7, 2009 for a permit modification to allow conversion from a binder system based on a phenol-formaldehyde resin to a binder system formulated around a starch-based resin at the Feura Bush facility, Owens Corning Insulating Systems, LLC (OCIS) presented supporting information (dated November 20, 2009 and March 9, 2010) requesting a determination regarding the applicability of the NESHAP for Wool Fiberglass Manufacturing (Subpart NNN) to operations at this facility following the binder conversion. The Department forwarded this request onto the United States Environmental Protection Agency (USEPA), which oversees the federal NESHAP program. In response, USEPA informed the Department on June 15, 2010 of its determination that, upon completion of the conversion to the starch-based binder system, the OCIS Feura Bush facility would no longer meet the definition of an affected facility in 40 CFR 63.1380 and, therefore, would no longer be subject to Subpart NNN. The conversion to the starch-based binder system at the facility was completed in February 2011 for the DM1 production line and in September 2011 for the DM2 production line. Therefore, because the facility no longer uses phenol-formaldehyde binders, it is no longer subject to the Subpart NNN requirements. The NESHAP for Wool Fiberglass Manufacturing lists three affected sources subject to the standards of Subpart NNN: glass-melting furnaces located at a wool fiberglass manufacturing facility; rotary spin wool fiberglass manufacturing lines producing a b onded wool fiberglass building insulation product; and flame attenuation wool fiberglass manufacturing lines producing a bonded heavy density product. Prior to the switch to a starch-based binder, the facility operated two glass-melting furnaces located at a wool fiberglass manufacturing facility and two rotary spin wool fiberglass manufacturing lines producing a bonded wool fiberglass building insulation product that were subject to Subpart NNN requirements. There is no flame attenuation wool fiberglass manufacturing line at the facility. Consistent with other Subpart NNN determinations by USEPA for similar wool fiberglass manufacturing facilities elsewhere, the following is the rationale that was used for the Subpart NNN non-applicability determination relating to the starch-based binder conversion. With the switch to a starch-based binder system from a phenol-formaldehyde binder, the facility no longer produces a bonded product and, therefore, does not produce building insulation as defined per Subpart NNN. Because the facility no longer produces building insulation per Subpart NNN, it does not meet the definition of a rotary spin manufacturing line. If there is no rotary spin manufacturing line or flame attenuation manufacturing line located at the facility, then the facility does not meet the definition of a wool fiberglass manufacturing facility in Subpart NNN.Permit ID: 4-0122-00004/00039 Facility DEC ID: 4012200004

Air Pollution Control Permit Conditions Renewal 1/Mod 4/Changes Only Page 33 DRAFT Additionally, since the facility is no longer defined as a wool fiberglass manufacturing facility, as a result of the switch to a starch-based binder (i.e., non-phenol, non-formaldehyde), then the glass-melting furnaces located at the facility are no longer subject to Subpart NNN because these furnaces are no longer located at a wool fiberglass manufacturing facility.
