Dear Ms. Tinsley:
Division personnel have reviewed and approved your application for a Major Modification of the
subject permit. Accordingly,we are forwarding the attached NPDES discharge permit. This Major
Modification is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Mernoranduni of Agreement between North Carolina and the U.S.Environmental Protection Agency
dated October 15, 2007 (or as subsequently amended).
The following changes have been incorporated into this Major Modification:
• A quarterly monitoring for Cd was added to the permit based on the results of the statistical analysis
of the effluent data.
• A quarterly monitoring for Tl was added to the permit based on the results of the statistical analysis
of the effluent data. The]unit was not added since the facility certified that Tl is not used in the
production. Monitoring is necessary to verify that Tl is not appeared in the discharge due to the new
scrubber operation.
• A quarterly monitoring for F was added to the permit to determine impact of die new scrubber
addition that is designed to remove the residual fluoride from the exhaust air.
• A quarterly monitoring for Hg was added to the pen-nit to implement a Statewide Mercury TMDL.
• A limit for Se was added to the permit based on the results of the statistical analysis of the effluent
data. A monthly monitoring for Se was added to the permit due to the introduction of the Se limit.

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 48%.
The permit holder shall perform at a minimum, uacr rterlit monitoring using test procedures outlined in the"North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revises!February 1998,or subsequent versions or"North Carolina Phase
Il Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998)or subsequent versions.The tests will be
performed during the inantlrs 6f February,May, August and November.Effluent sampling for this testing shall be performed at
the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a.failure or ChV below the permit limit,then
multiple-concenlration testing shall be performed at a minimum,in each of the two following months as described in"North
Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998)or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
inpairment of reproduction or survival.The definition of"detectable impairment,"collection methods,exposure regimes,and
further statistical methods are specified in the"North Carolina Phase II Chronic Whole Effluent Toxicity"rest Procedure"
(Revised-February 1998)or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form
(MR-1)for the months in which tests were performed,using the parameter code TGP3B for the pass/fail results and TEF3B

Dear Mr. Poupart:
The draft National Pollutant Discharge Elimination System permit and the application materials were
transmitted by your office to the U.S. Environmental Protection Agency on December 12, 2012. On
January 11, 2013, in accordance with Section IV(A)(12)(b) of the North Carolina/EPA Memorandum of
Agreement (MOA) and 40 Code of Federal Regulations (CFR) § 123.44(a), the EPA properly notified
you and the permittee that the EPA may use up to the full 90-day review period authorized by the MOA
and federal regulations. At your request, we have expedited and completed our review of the draft
permit. Please note that our review was limited due to incomplete information provided to us. We
provide the following comments and recommendations:
The draft pen-nit is a major modification with changes in effluent characteristics. Our comments and
recommendations are limited to the proposed modifications. The draft permit shows an expiration date
of May 31, 2014, the EPA is unable to determine definitively whether or not the modified permit limits
will cause or contribute to an exceedance of water quality standards.
e The draft fact sheet does not include the calculations associated with the reasonable potential
analysis or document how the permit limits were determined.
As stated earlier, the permit being modified will expire on May 31, 2014. Please note that upon renewal
of this pennit, EPA will review the permit proposed for reissuance per the North Carollna/EPA
Memorandum of Agreement (MOA), and may provide additional comments and recommendations when
the permit is reissued.

1.0 Proposed Changes S�C 3 Z I
• A quarterly monitoring for Cd was added to the permit based on the results of the
statistical analysis of the effluent data.
• A quarterly monitoring for TI was added to the permit based on the results of the
statistical analysis of the effluent data.The limit was not added since the facility certified
that Tl is not used in the production. Monitoring is necessary to verify that TI is not
appeared in the discharge due to the new scrubber operation.
• A quarterly monitoring for F was added to the permit to determine impact of the new
scrubber addition that is designed to remove the residual fluoride from the exhaust air.
• A quarterly monitoring for Hg was added to the permit to implement a Statewide
Mercury TMDL.
• A limit for Se was added to the permit based on the results of the statistical analysis of
the effluent data. A monthly monitoring for Se was added to the permit due to the
introduction of the Se limit.
2.0 Summary
PPG Industries Fiber Glass Products,Inc operates a fiberglass fiber manufacturing facility in
Lexington, NC. The Lexington plant currently concentrates the bulk of its fiberglass yarn
manufacturing on the textile industry as well as the printed circuit board industry.
Manufacturing begins with glass raw materials including limestone,silica,boron,clay and
fluorspar. These raw materials are blended in powder form and added to melt furnaces. The
batch-melt furnaces,operating at 28007 transform the batch into molten glass. The molten glass
is then drawn from the furnaces through electrically heated platinum bushings into continuous
fibers. These fibers are gathered into strands and either spooled or chopped into specified
Iengths. Water sprays cool the glass and keep strand contact points clean during the winding
process.

NPDDS Permit Fact Sheet— 02/01/13 PPG Industries/ Lexington Facility
Page 2 NCO004626
PPG's Lexington facility discharges through a single permitted outfall,001. This outfall is from
the.wastewater treatment plant and receives the following kinds of wastewater:
Sanitary(American Children's Home) ➢ Process WW
In-plant sanitary i Non-contact cooling water
Boiler feed > Sludge dewatering
As part of a settlement agreement reached in 1995, instream monitoring is not a current permit
requirement. The facility was required to monitor at 10 instream stations once during the
summer of 1995 and once in 1996. Monitored parameters were DO, temperature,conductivity,
pl-I, total phosphorus,nitrate, nitrite,ammonia and TKN, The monitoring was completed as
required and is not proposed with this renewal.
Current effluent limitations for BOD5 and TSS appear to be based on water quality protection and
not on federal guidelines. Extensive research was conducted during the 1998 renewal to
determine if any federal guidelines exist for such a manufacturing operation. Neither textile nor
glass guidelines applies to PPG's process. A review of the WLA file indicates that the limits
installed in 1983 were based on BPJ,
This Major Modification is required to accommodate the installation of the new packed-bed
counter flow wet scrubber in series with the exhaust of existing air pollution controls on its fiber
glass manufacturing Furnace 509.The scrubber will be installed to comply with the new state air
emission requirements.The purpose of the new wet scrubber is to remove residual fluoride from
the exhaust air.The scrubber will generate approximately 4,300-7,200 g/day of wastewater.The
blowdown stream will be comprised of once-through city intake water,with addition of sodium
hydroxide or potassium hydroxide,as needed,to maintain neutral pH of the scrubber blowdown
before it comingles with other wastewater.The combined wastewater will be processed though
the treatment plant.
The facility discharges to North Potts Creek. North Potts is tributary to High Rock Lake and is
not listed on the State's 303(d) list
10 Compliance Summary
The facility has an excellent compliance history,during the review period (07/2009 through
10/2012) the facility had no Notices of Violations. The Iast compliance evaluation inspection
conducted on 02/19/2008 concluded that facility is"well maintained and operated".
4,0 WEi Test
PPG Industries has been consistently passing WET test during the review period with one
exception. The subsequent monthly WET tests passed. Chronic P/F Q 487o (also recommended
with renewal)
5.0 RPA
The Reasonable Potential Analysis (RPA) was conducted based on the results of a trial with a
small-scale temporary pilot scrubber. The RPA is conducted in accordance with the EPA
Technical Support Document for Water Quality-based Toxics Control. The following parameters
were analyzed: As,Al,Ag,Cd,Co,Cu, Mo,Ni,Se,Sb,TI,and Zn.Please see attached.The results
indicate that Se and TI require limits. However, the PPG claimed that TI is not used anywhere in
the manufacturing process and the positive bench-test result is likely due to the contamination of
the bench-test equipment from the previous trial. Therefore, the limit for TI will not be added,
only quarterly monitoring.The permit will be renewed in 2014 and TI will be re-evaluated.

Re: PPG Industries Fiber Glass Products, Inc.— Lexington Facility
Comments on Draft NPDFS Permit NCO004626
Dear Mr. Chernikov:
PPG Industries Fiber Glass Products, Inc. ("PPG") received and reviewed the draft NPDFS Permit
NCO004626 issued by NCDENR on December 5, 2012. This permit will allow PPG to treat water
from a wet scrubber air pollution control device through its existing wastewater treatment plant.
This letter submits PPG's comments on the draft permit within the 30-day comment period that ends
January 4, 2013.
PPG's comments concern the new permit conditions for cadmium, thallium, and selenium. As
explained in the permit application; these constituents are not expected to be present in the treatment
plant's effluent, however they cannot be conclusively demonstrated as not-present until after
construction and operation of the full-scale scrubber. PPG does not yet have data that accurately
represents the treatment plant's final wastewater effluent after a full-scale scrubber's influent has
undergone the full treatment process. Therefore, the following modifications are requested to
condition A(]) of the draft permit:
1. Cadmium. Add a footnote to the table in condition A(I)to reduce the monitoring frequency
to annual if quarterly monitoring resuhs demonstrate that cadmium is not detectable for 4
consecutive quarters. �• l r
r - _
DEC 2 9' 2012 --7l'
;;r Y

2. 'thallium: Add a footnote to the table in condition A(l) to reduce the monitoring frequency
to annual if quarterly monitoring results demonstrate that thallium is not detectable for 4
consecutive quarters.
3. Selenium: Add a footnote to the table in condition A(1) to allow a one year implementation
schedule ( from the permit's effective date) before the limit comes into effect. Also, reduce
the monitoring frequency to annual if monthly results demonstrate that selenium is not
detectable for 12 consecutive months.
Please contact me if there are questions regarding the above comments. Thank you for your
timely issuance of the draft permit and consideration of these comments.
Sincerely.

Introduction
The PPG Industries Fiber Glass Products, Inc. ("PPG") facility in Lexington, NC operates a wastewater
treatment plant ("WWTP") authorized by NPDI S Pen-nit #NC0004626. To comply with air emission
requirements, the facility must add a wet scrubber to the exhaust of existing air pollution controls on its fiber
glass manufacturing Furnace 509. The wet scrubber will remove residual fluoride from the exhaust air. The
construction timeline for the wet scrubber is January 2013 with startup anticipated by the end of February
2013. A permit modification is requested to add up to 7200 gallons/day of scrubber blowdown water to the
influent of the existing WWTP. This permit modification application is for treatment of the wet scrubber's
blowdown water. Since the existing pen-nit expires May 31, 2014, this application also includes all
information required for this facility's permit renewal.
Project Description
A new wet scrubber's blowdown stream will be added to the influent of the existing WWTP. The blowdown
stream will be comprised of once-through city intake water, with addition of sodium hydroxide and/or
potassium hydroxide, as needed, to maintain neutral pH. No changes will be made to the design, equipment,
operation, or capacity of the existing WWTP in order to process the scrubber flow, which represents only a
small contribution of the total daily flow of wastewater processed.
In preparation for this project, PPG conducted a trial with a small-scale ten orar pilot scrubber on a slip-
stream of the furnace exhaust. ow down water unit was evaluated for aquatic toxicity,
orgImms, and-trt rTI constituents to profile anticipated characteristics of this wastewater stream, n a dition a
_beach-scale treatability study was conducted to ensure that the WWTP can adequately process the new
wastewater stream. All results indicate that the blowdown water is compatible with existing WWTP
operations and vi iave no impact on existing permitted parameters. The scrubber blowdown water will not
add any new chemical constituents to the existing WWTP influent or effluent.
The only change�ropo e 1 by this project is to add an average of 5,760 gpd of pEl adjusted blowdown water to
the existing WWTP influent, per the attached Figure 2 -Flow Diagram. The maximum blowdowu_�lAiiyf ,
will be 7,200 gpd which is less than 2%of the WWTP's current daily flow. The WWTP has adequate capacity V
to rea up to 600,000 gpd and no change is required to the permitted discharge flow. The blowdown water
will be routed to existing drainage systems within the plant. No piping changes are required to route the
blowdown water to the WWTP.
The proposed addition of scrubber blowdown water to the existing WWTP influent is not expected to have any
impact on the current WWTP operations or its current permit:
No physical changes to piping or equipment will be made to the WWTP processes.
• "There will be no change to the design or operation of the existing permitted wastewater treatment
facility.
• There will be no change in the wastewater treatment facility's pennitted discharge flow.
• There will be no change to the treatment facility's influent or effluent profile of chemicals or
toxicity parameters.
• The wastewater treatment facility's existing permit application will continue to accurately
represent its design and operation.
• The facility's existing wastewater permit continues to accurately represent the operation and the
facility will continue to be able to comply with all existing permit terms and conditions.

Sample Reporting and Averaging
Sample reporting and averaging was provided in Form 2C as per NC DhNR DWQ's memo "Directions for
Completing Monthly Monitoring Reports" dated September 1, 2000. These instructions provide guidelines
wills respect to rules for reporting and averaging less than detectable "<" values. (e.g., a sample result with a
value of less than the detectable limit is considered to equal "zero" when calculating monthly and long-term
aritlimetie averages). Also per NC DFNR DMR reporting guidelines, fecal coliform monthly and long-term
averages were calculated using a geometric mean, where values less than the detection limit of#/100 ml were
reported as#/100 mi.
Signature Authority
`there is no change requested in signature authority for monthly monitoring report requirements. Signature
authority for monthly monitoring reports as a "Duly Authorized Representative" per 1 SA NCAC
2B.0506(b)(2)(D), will remain unchanged and is delegated to the person holding the title of Maintenance
Manager.

Sludge Management Plan
PPG Industries generates both primary and secondary sludge residuals as part of the industrial wastewater
treatment process. The primary sludge results from a lime precipitation process and the secondary sludge is
gencrated in an activated sludge biological treatment plant.
A schematic of the sludge management system is presented in Figure No. 3. The waste primary and
secondary sludge is dewatered on a belt filter press.
The belt dewater press is a U.S. Filter model 131IC-1600-7C. This is a 1.6 meter process with a solids
processing capacity of 9.6 dry tons/day (3,494 dry tons/yr). This unit dewaters the solids from the
stabilization decant/thickener. There is more than adequate capacity to handle all of the sludge generated
onsite. The dewatered solids drop into an open top roll off dumpster, and are disposed of at the Davidson
County Landfill. A copy of the landfill approval for this disposal is attached.
PPG typically operates this unit on a 4-5 day/week basis for 6 hours/day (24 -30 hr./week operation). This
mode of operation can handle 100% of the solids generated. The system could be operated up to 7
days/week at 20 hr/day operation (140 lu-s/week). Therefore, the system will use less than 20 percent of the
available dewatering capacity.
The PPG wastewater treatment system is designed to provide operating flexibility. Therefore, PPG can
adjust to changing waste loads and changes in environmental regulations.

RE: Approval Letter for Dewatered Sludge Waste
Dear Brigette,
We have contacted the NC Department of Environment and Natural Resources and have checked to make
sure that the Davidson County Landfill can accept the Dewatered Sludge generated from your Industry.
At this present time,the Davidson County Solid Waste Department will approve 1 and accept the new waste
stream(Dewatered Sludge)generated from PPG industries. The Upping fee"I be$10 per cubic yard.
In the advent that local, state,or the Federal laws were to change in reference to disposal of this waste,this
agreement letter will be void.
Thank you,

Attached Description of Wastewater Treatment Process
PPG Industries Fiber Glass Products Inc. — Lexington, NC
The wastewater is generated from the fiberglass manufacturing operation, the boiler operations,
non-contact cooling blow down, plant sanitary wastewater and the sanitary wastewater from the
American Children's Home. The wastewater is treated in a 0.6 MGD treatment facility. A
process flow schematic is attached (Figure 3). The wastewater treatment processes includes
screening of the process wastewater and comminutors for the sanitary wastewaters. All wastes
are then equalized, chemically treated using lime and ferric chloride and settled in a primary
clarifier. The primary clarifier effluent is treated in an activated sludge system followed by a
chlorine contact chamber, dechlorination and activated carbon columns. Currently 100% of the
treated effluent is discharged to North Potts Creek.
The primary and secondary sludges are combined in a stabilization decant/thickener followed
by belt press dewatering. The decanted supernatant can be returned to the wet well or treated
separately in one of the activated sludge aeration basins. The dewatered sludge is transported
to the Davidson County Landfill.
The data presented in Form 2C Section V is based on plant operating data for the period
September 2011 to August 2012 as reported in the Monthly Discharge Monitoring Reports.
Supplemental effluent analysis was conducted on samples collected on October 19, 2012 and
November 1, 2012 for items not routinely monitored by the permittee.

CONTINUED FROM PAGE 3 OF FORM 2-C 110000346082 001
PART C- If you are a primary industry and this outtalk contains process wastewater,refer to Table 2o-2 in the instructions to determine which of the GC/MS fractions you must test for,Mark-X'in column 2-a for all such GCIMS
fractions that apply to your industry and for ALL toxic metals,cyanides,and total phenols.If you are not required to mark column 2-a(secondary industries,nonprocess wastewater oulfalfs, and nonrequired GC/MS
fractions),mark'X"in column 2-b for each pollutant you know or have reason to believe is present.Mark'X'in column 2-c for each pollutant you believe is absent,If you mark Column 2a for any Pollutant,you must
provide the results of at least one analysis for that pollutant.If you mark column 2b for any pollutant,you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be
discharged in Concentrations of 10 ppb or greater.If you mark column 2b for acrolein,acrylondrile,2,4 dinitrophenol,of 2-methyl-4,6 dinitrophenol,you must provide the results of at least one analysis for each of these
pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater.Otherwise,for pollutants for which you mark column 2b,you must either submit at least one analysis or
briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part:please review each carefully.Complete one table(all 7 pages)for each outfall. See instructions for
additional details and requirements.

Wet Scrubber Pilot Trial Summary
On October 10, 2012, PPG submitted analytical results to NCDENR for water samples collected during
operation of a pilot scrubber trial. A small pilot scale test scrubber was operated for 2 weeks on a slip-stream
of the furnace exhaust, and blowdown water was collected in totes and sampled. The samples were analyzed
in an attempt to profile potential constituents in water from a future full-scale scrubber that would be newly
constructed on site. The water samples were analyzed for metals, solids and organics.
The samples' results did not detect any materials expected from PPG's processes, however,some
unknown metals were detected. Small quantities of some metals detected in the pilot blowdown water
samples are believed to be contaminants from the rental pilot scrubber equipment, rather than process
exhaust. The pilot unit supplied by the vendor was used in trials in other manufacturing industries
before use at PPG. The most recent of which was a gold refining facility where they were looking to
achieve product recovery of precious metals; the owner of the scrubber noted it is possible for trace
amounts,of metals to remain in the sump. The pilot scrubber's packed substrate may trap metal
contaminants and it is not possible to completely clean the substrate between uses. The vendor does
not replace packing between uses at different manufacturing sites. It is believed that the low-levels of
detected metals are artifacts from the pilot unit,and are not expected to be present in a newly fabricated
scrubber-and would not be expected in the effluent following full treatment by the wastewater
operations. Constituents in city water, fiber glass raw materials,and fuels were compared to the pilot
analytical results to assess which constituents may be present. Metals such as antimony,barium,
thallium and silver are not used as raw materials,are not known to be present in any raw materials used
at Lexington, and are not products of natural gas combustion. Trace quantities of cobalt and manganese
could possibly be generated from natural gas combustion. However, if present, that quantity would be
approximately less than 0.1 lb. /yr. based on typical annual usage of natural gas.
In summary,the data submitted to NCDENR on October 10, 2012 only reflects the pilot trial,but is not
representative of the blowdown from the proposed new scrubber or final effluent of the WWTP after full
treatment of the new scrubber's water. The pilot's samples confirmed that known constituents in PPG's
process were not detected. However, unknown trace metals are likely artifacts from the pilot unit.

Subject: Permit Determination Request for Treatment of Wet Scrubber Blowdown Water
PPG Industries Fiber Glass Products,Inc.
Lexington, NC Facility—Wastewater Treatment Plant
NPDES Permit NCO004626
Dear Mr. Chernikov:
The PPG Industries Fiber Glass Products, Inc. Lexington, NC facility ("PPG") currently operates a
wastewater treatment plant ("WWTP") authorized by NPDES Permit#NC0004626. This letter requests
a permitting determination for a project that will add a new wastewater stream to the influent of the
WWTP, PPG believes this minor addition does not trigger any permitting requirements for the reasons
provided herein, This letter is to notify NC DWQ of the proposed change and to request confirmation
that a permit application is not required before this project commences. A description of the project is
outlined below.
Project Description
To comply with air emission requirements, the Lexington facility must add a packed-bed counter flow
wet scrubber in series with the exhaust of existing air pollution controls on its fiber glass manufacturing
Furnace 509. The purpose for the new wet scrubber is to remove residual fluoride from the exhaust air
that could not be adequately removed by the existing dry-scrubber and baghouse Emission Control
System. The facility recently submitted an air permit application for the wet scrubber to North Carolina
DAQ (Raleigh Office), and their review is in progress. The construction timeline for the addition of the
wet scrubber is January 2013, with startup anticipated by the end of February 2013. Once the wet
scrubber commences operation, it will generate approximately 3-5 gallons/minute (4,300-7200
gallons/day) blowdown water. The blowdown stream will be comprised of once-through city intake
water, with addition of sodium hydroxide and/or potassium hydroxide, as needed, to maintain neutral pH
of the scrubber blowdown before it comingles with other wastewater. The combined wastewater will be
processed through the treatment plant.

r
In preparation for this project, PPG conducted a trial with a small-scale temporary pilot scrubber on a
slip-stream of the furnace exhaust. Blowdown water from the pilot unit was evaluated for aquatic
toxicity, organics, and metal constituents to profile anticipated characteristics of this wastewater stream.
In addition, a bench-scale treatability study was conducted to ensure that the WWTP can adequately
process the new wastewater stream. All results indicate that the blowdown water is compatible with
existing WWTP operations and will have no impact on existing permitted parameters. The scrubber
blowdown water will not add any new chemical constituents to the existing WWTP effluent.
Proposed Changes
The only change proposed by this project is to add up to 4300-7200 gallons/day of pl-I adjusted blowdown
water to the existing WWTP influent, per the schematic shown on Attachment 1. The maximum
blowdown daily flow will be 7,200 gallons/day which is approximately 1% of the W WTP's current daily
flow. The WWTP has adequate capacity to treat up to 0.6 MGD and no change is required to the
permitted discharge flow. The blowdown water will be routed to existing drainage systems within the
plant. No piping changes are required to route the blowdown water to the WWTP. No physical changes
to piping or equipment will be made to the Wwrp processes. No changes will be made to any operations
in the current WWTP.
Impact of Proposed Changes
Tile proposed addition of scrubber blowdown water to the existing WWTP influent is expected to have no
impact on the current WWTP operations or its current permit:
• There will be no change to the design or operation of the existing permitted wastewater treatment
facility.
• There will be no change in the wastewater treatment facility's permitted discharge flow.
• There will be no change to the treatment facility's effluent profile of chemicals or toxicity
parameters.
• The wastewater treatment facility's existing permit application will continue to accurately
represent its design and operation.
• The facility's existing wastewater permit continues to accurately represent the operation and the
facility will continue to be able to comply with all existing permit terms and conditions.
The facility wishes to initiate operation of the new wet scrubber by late February 2013. This letter is to
inform NC DWQ of the proposed change and confirm that a permit application is not required, since the
treatment of the scrubber water will not affect the current permit's terms, conditions, or limitations.
Should you have any questions regarding the above information, or if a phone call or meeting is necessary
to discuss this in more detail, please contact Brigette Tinsley at 336-357-8151 Bxt 317.
