A (3.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) — OUTFALL 001
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 33%.
The permit holder shall perform at a minimum, quarterlu monitoring using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or
"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions. The tests will be performed during the months of January, April, July and October. 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 -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II 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 impairment 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 Test 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. If reporting pass/fail results using the
parameter code TGP3B, DWR Form AT-1 (original) is sent to the below address. If reporting Chronic Value
results using the parameter code THP3B, DWR Form AT-3 (original) is to be sent to the following address:

2.0 Background
PPG Industries Fiber Glass Products, Inc. operates a fiberglass fiber manufacturing
facility in Shelby, NC. The Shelby plant currently concentrates the bulk of its
fiberglass manufacturing on the reinforced plastics market.
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 2800oF, 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 lengths. Water sprays cool the
glass and keep strand contact points clean during the winding process.
A "binder", which is water based, is applied to the individual fibers as they are drawn
from the furnaces before being gathered into strands. The binder is a proprietary
mixture of resins, film formers, lubricants, surfactants and coupling agents emulsified

in a water base. The majority of the wastewater treated by the treatment plant is spray
water, lost binder and cleaning water.
Additional wastewater is received from Hanwha. Hanwha is a PPG joint venture with
GE and produces a fiber glass reinforced polypropylene sheet material that is sold to
molders. This is considered a plastics laminating process and is cover under 40 CFR
463. The manufacturing process is dry, so that the wastewater sent to PPG is either
cooling water, cleaning water or domestic wastewater. Therefore, no allocation based
on 463 is proposed.
3. Wasteload Allocation Summary
This permit was first issued on May 31, 1978. The permit was summarily adjudicated.
It is not entirely evident why the permit was adjudicated, however a review of
historical files seems to indicate that the adjudication was filed because of a
disagreement with limit development. At issuance, final effluent limitations were
based on 40 CFR 410.32, Subpart C: Textile Dry Processing. While the permit was
being adjudicated, interim limits were established based on the results of a field
calibrated water quality model. Upon resolution of the adjudication (it was determined
that textile guidelines did not apply to PPG's discharge), the permit was reissued in
August of 1979 with water -quality limitations based on the results of the model. This
original series of wasteload allocations was based on a discharge flow of 0.875 MGD.
The permit was renewed in 1985 with a change in allocation, however the reason for
the change is not evidenced in the files. In 1988, Jaclde Nowell completed a wasteload
allocation for this facility at an expanded flow of 1.3 MGD. The increase in flow was
based on process modifications in the manufacturing facility. Jackie evaluated PPG's
discharge with a level B model and developed appropriate water quality -based
limitations for BOD5 and NH3-N.
The current effluent limitations for BOD5 and NH3-N are based on the level B model
run in 1988, while the current TSS limits are BPJ, apparently based on the BOD5
limits developed as resolution to the 1978/79 adjudication.
Extensive research was conducted during the 1984 renewal process to determine if
any federal guidelines exist for such a manufacturing operation. Lacy Ballard of PPG
was contacted for a detailed description of the manufacturing process and associated
end products. Don Anderson and Hugh Wise were contacted at EPA in D.C. regarding
the applicability of textile and glass guidelines. After conversations with both, it was
determined that neither set of guidelines applies to PPG's process. As stated earlier,
PPG does accept wastewater from Hanwha. Hanwha's operation falls under the
authority of 40 CFR 463, Plastics Laminating. However, manufacturing at Azdel is a
dry process. Azdel's wastewater is largely cooling water, cleaning water and domestic
wastewater. Therefore, guidelines do not apply to this aspect of PPG's effluent either.
PPG operates two outfalls, 001 and 002.
Outfall 001
Outfall 001 is the effluent from the wastewater treatment plant and receives the
following kinds of wastewater:
• Sanitary
• Research

Outfall 002
Outfall 002 is a non -contact cooling water outfall and is permitted in accordance with
the general permit for non -contact cooling water.
4.0 RPA
Reasonable Potential Analyses (RPA) were conducted for lead, copper, zinc, chlorides,
and fluoride for outfall 001 (please see attached). The results of RPA indicate that no
limits are needed for these parameters. While the maximum predicted concentration
for copper and zinc exceeded the allowable concentration, no limits are proposed as
the facility is not experiencing whole effluent toxicity.
5.0 Compliance Summary
A review of DMR data has indicated that facility received 6 notices of violation during
the last permit term. One violation (oil and grease limit excursion) occurred in 2008,
the rest occurred in 2010 (4 ammonia limit excursion and 1 BOD limit escusrion). It
appears that the facility has addressed the existing issues.
6.0 Toxicity Testing
Type of Toxicity Test:
Existing Limit:
Recommended Limit:
Monitoring Schedule:
Chronic P/F
001: Chronic P/F @ 33%
001: Chronic P/F @ 33%
January, April, July, October
The facility has been consistently passing its WET during the last permit term.
7.0 Instream Monitoring Requirements
PPG currently monitors dissolved oxygen, temperature, and conductivity instream.
This renewal recommends maintaining instreamn monitoring for DO, temperature, and
conductivity.
8.0 Permit Limits
• BOD limits in the permit are based on the water quality model.
• Ammonia limits in the permit are based on the water quality model. The
Division uses ammonia criteria that were developed by EPA: 1 mg/L - summer;
1.8 mg/L - winter.
• DO limit in the permit is based on the water quality model.
• TRC limit in the permit (both outfalls) is based on the North Carolina water
quality standards 115A NCAC 2B .02001.
• pH limit in the permit (both outfalls) is based on the North Carolina water
quality standards [ 15A NCAC 2B .02001.
• TSS limits in the permit are based on the Best Professional Judgment.
• Oil and Grease limit in the permit are based on the Best Professional Judgment.

9.0 Proposed Schedule for Permit Issuance
Draft Permit to Public Notice: October 8, 2013
Permit Scheduled to Issue: December 2, 2013
10.0 State Contact
If you have any questions regarding any of the above information or the attached
permit, please contact Sergei Chernikov at [phone].
11.0 Changes in the Final Permit
• Proposed federal regulations require electronic submittal of all discharge
monitoring reports (DMRs) and specify that, if a state does not establish a
system to receive such submittals, then permittees must submit DMRs
electronically to the Environmental Protection Agency (EPA). The Division
anticipates that these regulations will be adopted and is beginning
implementation.
The requirement to begin reporting discharge monitoring data electronically
using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet
application has been added to the permit. [See Special Condition A (6.)].

We are pleased to enclose an original, signed NPDES Permit Renewal Application package along
with the two required photo copies. This is for the PPG Industries Fiber Glass Products, Inc. facility in
Shelby, NC. We are requesting the reissuance of NPDES Permit No. NC0004685. The primary SIC
Code for facility operations is 3229-Pressed and Blown Glass- not elsewhere classified. Approximately
one percent of the waste load is from the Hanwha sheet laminate facility (SIC 3083). The wastewater
outfall, Outfall 001, is located at latitude 35 degrees, 20 minutes, 26 seconds, by longitude 81 degrees,
37 minutes, 0 seconds with the receiving water being Brushy Creek.
There have not been any changes to the facility since the previous permit renewal. We request that all
NPDES Permit issues be directed to Mr. Richard Young, Senior Engineer Associate, Environmental.
The facility Manufacturing Manager, Maintenance Manager, and Enterprise Excellence Manager are
authorized to sign all reports required by the permit.

As part of this permit renewal package, we have included:
1. Cover letter;
2. Introduction;
3. EPA Form 1;
4. EPA Form 2C;
5. Narrative description of the sludge management plan; and
6. Analytical data
The data presented in Form 2C Section V is based on plant operating data for the period January 1, 2012
to December 2012 and special analysis conducted by Pace Analytical Services Inc. Copies of the Pace
reports on the special analysis have been provided in the package (Tab G). The plant operating data is
from monthly DMR submittals.
Please feel free to contact me if you need any additional information or if you have any questions
regarding this submittal.

INTRODUCTION
PPG Industries Fiber Glass Products, Inc. (PPG) operates a Fiber Glass manufacturing facility in
Shelby, North Carolina. This facility operates under the existing NPDES Wastewater Permit
Number NC0004685 which expires on August 31, 2013. This permit allows the facility to
discharge treated wastewater at 1.3 million gallons/day to outfall 001 and to discharge non -
contact cooling water to outfall 002. In addition to PPG's Fiber Glass Manufacturing operation,
a Hanwha sheet laminate manufacturing facility is located adjacent to the PPG site and
discharges approximately 10,000 gallons per day to the PPG Wastewater treatment plant for
treatment. Wastewater from PPG and Hanwha operations are sent to PPG's wastewater plant for
treatment and both operations are covered under the existing permit. Additional details and
clarification for several items relevant to this permit application are highlighted below.
1. SIC Codes and Outfall 001 Testing
The SIC code for the Hanwha (sheet laminate facility) is 3083. The Hanwha site
discharges 10,000 gallons wastewater per day to the PPG wastewater treatment plant for
treatment. This discharge makes up approximately 1/100th of PPG's wastewater flow.
Therefore, as required for the 3083 SIC code, PPG performed volatile compound testing
on Outfall 001. Results from this testing are incorporated into Form 2C of this
application.
2. Outfall (002) Testing
Outfall 002, the primary stormwater outfall, is currently permitted for the discharge of
non -contact cooling water. Therefore, PPG conducted the testing as set forth in Form 2C.
This testing also included the required volatile compounds for SIC codes 3083.
3. Wet Weather Only Outfalls
Outfalls 003, 004, 005, 006, 007 and 008 are covered under the General Stormwater
Permit #NCG070000, Certificate of Coverage #NCG070015. These outfalls are wet
weather outfalls only and would contain little, if any, drainage from industrial areas. For
this renewal, testing was not conducted on these wet -weather outfalls.
4. Sample Reporting and Averaging
Sample reporting and averaging was provided in Form 2C as per NCDENR DWQ's
"Directions for Completing Monthly Monitoring Reports" dated March, 2009. These
instructions provide guidelines with respect to rules for reporting and averaging less than
detectable "<' values. (i.g., a sample result with a value of less than the detectable limit
is considered to equal "zero" when calculating monthly and long-term arithmetic
averages). Also per NC DENR DMR reporting guidelines, fecal coliform monthly and
long-term averages were calculated using a geometric mean.
5. Signature Authority
There will be no change requested in signature authority for monthly monitoring report

requirements. Signature authority for monthly reports as a "Duly Authorized
Representative" per 15A NCAC 213.0506(b)(2)(1)), will remain unchanged and is
delegated to the people holding the titles of Manufacturing Manager, Maintenance
Manager and Enterprise Excellence Manager.

SLUDGE MANAGEMENT PLAN
The wastewater treatment plant (W WTP) sludge generated by the Shelby facility is a mixture of
both primary and secondary sludges. The primary sludge is the result of clarification using lime,
aluminum chloride, polymers and coagulants to achieve floc formation and settling. The
secondary sludge is waste activated sludge from the biological treatment system. The secondary
sludge also contains bentonite clay and a small amount of ferric chloride.
Both sludges are combined in a sludge thickener/storage tank prior to dewatering. Polymer
addition and mechanical mixing, along with dilution water, are required to prepare the sludge for
the belt press. The sludge is then pumped to the belt press for dewatering.
The belt press has both a gravity drain section and a pressure section where the water is removed.
Typically, the solids are increased from 4-5% as it leaves the storage tank, to 25-30% solids as
discharged from the belt press. The dewatered sludge is transported via screw conveyors to a
roll -off box. The water is routed back to the head of the W WTP.
Before the roll -off box is picked up for disposal, a paint filter test is conducted on the sludge to
ensure that free liquids are not present. The dewatered sludge is then taken to a permitted, lined
landfill for disposal.

Outfall #002 is the primary stormwater outfall for the Industrial portions of the property.
Cooling water discharges from the outfall are permitted under #NC0004685.
Stormwater Discharges are covered under the General Stormwater Discharge Permit #NC070000,
CDC #NCG070015
Stormwater Peak Flows were calculated using the Rational Method (Q= CIA) where:
Q = peak flow (cfs)
C = Runoff Coefficient (where: 0.9 = Impermeable, 0.8 = Graveled, 0.3 = Grassed, 0.1= Wooded)
I = Intensity
A = Area (acres)
Note: The above peak flow for stormwater was calculated using an intensity of 1"/hr.
The runoff coefficient (C) used was 0.76 based on the following estimate: 80% Industrial, (0.9).
