Discharged Water Permit Application Report 3
Mr. Davidson:
The purpose of this letter is to present the results of Low&Bonar Inc.'s fourth discharged water sampling and
analysis event. This effort was completed to demonstrate the effects of actions taken to mitigate and address
discharges of cooling tower blowdowns, condensate waters,and once-through cooling waters to Hominy
Creek.
Over the past six months Low&.Bonar has made significant infrastructure changes to reduce impacts to
surface waters. These changes include:
1. Reduced non-contact cooling water through Cooling Towers.
2. Reduced non-contact cooling water through Extruders.
3. Recycled non-contact boiler condensate water.
4. Installed water flow meters.
5. Installed a dechlorination system.
We believe that this report—and the reports for the three previous sampling events— demonstrates that Low
and Bonar is now and has been substantially in compliance with North Carolina Surface Water Pollutant
Discharge Limits. Moreover,this report shows that Low&Bonar has,based upon preliminary data,reduced
its purchased water and discharged water.
Please review the results of our infrastructure and operational changes. We believe that you will agree that a
General Permit is appropriate for our facility.

Discharge Water Study-Report 4
The purpose of this letter is to present Low&Bonu's fourth report of sampling and analysis
activities undertaken to complete a Notice of Intent to the Division of Water Resources. This
report is of wastewater discharge pollutant concentrations in the compliance point and of the
impact of those waters on an un-named tributary to Hominy Creek in Enka,NC.
The information contained in this report supplements Table 4 in Attachment D of the Notice
of Intent that was filed with your office on December 18,2017. That document contained
preliminary data only-we had not yet received the final laboratory analysis report when it
was filed.
Thank you and Ms. Wiggs for your time and input during the past several months. We assure
you that Low&Bonar is completely committed to resolving our permitting issue and to
protecting water quality in Hominy Creek. We will work with your staff to ensure continuous
compliance.

EXECUTIVE SUMMARY-DISCHARGED WATER STUDY
Low&Bonar Inc.has compiled additional information regarding water discharges to surface waters of
the State for review by the North Carolina Department of Environmental Quality's Water Resources
Section. The information contained in this and four previous sampling and reporting campaigns
comprises a comprehensive water discharge evaluation.
This report is of a sampling and analysis campaign on December 5,2017,is preceded by four other
sampling and reporting campaigns. Reports of July 6,July 13,August 2,and October 19 campaigns were
previously reported to the Water Resources Section.
This report provides discharge water pollutant concentrations from two(2)sources or intermediate points.
These discharge water sample locations are the same as in all previous campaigns: Slim Tank and the
East Ditch. The East Ditch—an unnamed tributary to Hominy Crock—had been the wastewater sampling
location(i.e.,compliance point)for several years of reporting under a National Pollutant Discharge and
Elimination System permit.
However,this and previous reports recommend the`Slim Tank' as the future wastewater sampling
location. The Slim Tank is inside the processing building and is the confluence of all wastewater before
any mixing with groundwater infiltration or stormwater in the combined discharge water piping system.
Over the course of all our activities over the last six months the relative pollutant concentrations at these
locations have not substantially changed.
This report includes two important equipment additions at the Slim Tank—the new discharged water
permit compliance point—and the Flood Gate—the new stormwater permit compliance point:
1. Flow Meter Installation in the Slim Tank and the Flood Gate.
2. De Chlorination System Installation in the Slim Tank.
This report—as with three previous reports—demonstrates that water discharges from the Low&Bonar
Inc.facility substantially comply with North Carolina 15A NCAC 02B Surface Water Standards and
Protective Values. Exceptions and clarifications of this statement are addressed below.
1. Two metals—copper and zinc—are discharged at values exceeding regulatory limits.
Copper and zinc concentrations in the new discharge compliance point(i.e.,Slim Tank)are at
concentrations of 0.0308 and 0.156 milligrams per liter(mg/L)respectively;the acute regulatory
limits are 0.0036 and 0.036 mg/L respectively. Table 2 lists all analytical results.
To put copper and zinc concentrations into perspective,City Water was tested at the entrance to
the property (i.e,the security office)and at an interior location(i.e.,the maintenance restroom)
approximately at the center of the manufacturing process. Copper concentrations at the property
water inlet point were less than(<)0.005 mg/L and zinc were 0.112 mg/L. Copper
concentrations at the center of the manufacturing process were less than(<)0.005 mg/L and zinc
were 0.287 mg/L.
Of note are that average City Water copper and zinc concentrations of North Fork reservoir water are
0.007 and 0.2 mg/L respectively. Thus,City Water supplied to Low&Bonar exceeds the State
regulatory discharge limits.
Low&Bonar Inc.—NPDBS Discharged Water Report4 1

Both copper and zinc are considered to have water system sum)ly and infrastructure sources
rather than process sources.
Another metal—molybdenum—was previously discharged from the facility. Molybdenum's only
source was a water treatment chemical used in the Cooling Towers. Our water treatment supplier
of this chemical used molybdenum as a tracer(i.e.,as molybdenum concentration values decrease
the supplier adds more of the entire formulation). The water treatment chemical supplier has
removed molybdenum from this formulation.
2. Totalizing flow meters were installed in the Slim Tank and in the Flood Gate on October 31,
2017. The metered flow data confirm that significant discharge reductions have been realized
from recent equipment changes to the 21 extruder cooling water points and seven(7)cooling
towers.
Discharge water flow rates in this report are based upon the measured daily volume the day of
sampling. In Table 1,that volume is compared to the flow meter averages over the weekly and
monthly averages of operation.
3. As reported in Report 3,Total Residual Chlorine is discharged from multiple sources;some are
once-through cooling waters that discharge essentially City Water(e.g.,extruders)but most are
cooling tower blowdowns. Note that City Water—which is used in both processes—Total
Residual Chlorine concentration averages about 1.4 milligrams per liter(mg/L).
Prior to installation of the de-chlorination system, Total Residual Chlorine concentrations in the
new discharge compliance point(i.e.,Slim Tank)ranged from 0.4 to 0.8 milligrams per liter
(mg/L);the regulatory limit is 0.017 mg/L.
Recently,after installation of the de-chlorination system,Total Residual Chlorine at the Slim
Tank and East Ditch compliance points has been at concentrations of less than 0.017 mg(L at both
points(see Figure 2 for sampling locations).
Our conclusion is that Low&Bonar Inc. is in compliance with the Total Residual Chlorine
standard in the Slim Tank;which is an internal sampling point that is being proposed as the new
"compliance point".
4. As reported in Report 3,Boiler steam condensate water was discharged from several receivers
and condensate drip legs to the stormwater collection/discharge system. Boiler condensates have
now all been returned to the boiler(i.e.,recycled)or rerouted to MSD.
5. As reported in Report 3,with reductions of water discharged from the Extruders and Cooling
Towers the amount of purchased City Water has decreased.

CHRONOLOGY
On May 22,2017,Low&Bonar Inc. conducted a Low&Bonarvfacility-wide requested inspection with
North Carolina Department of Environmental Quality staff concerning compliance with stormwater
regulations.
During that inspection,several other discharged water issues arose. As a follow-up to that inspection Ms.
Linda Wiggs of the Division of Water Resources sent to Low&Bonar Inc. in a June 12 email an
Information Request for water discharge sources,rates, and pollutant concentrations, A response to DWR
from Low&Bonar was dated June 15.
On June 19,the Water Resources Section issued a Notice of Violation and Intent to Assess Civil Penalty
(NOV-2017-DV-0148,Incident No.:201701034)to Low&Bonar Inc.
Low&Bonar Inc. attended a meeting with Water Resources Section staff on June 23. During that
meeting Water Resources Section staff clarified the scope of Ms. Wiggs' requested information and Mr.
Landon Davidson identified other tasks in an Information Request dated June 23. Those data,including
estimates of the volume of wastewater discharged daily,list of biocides and any other additives in
wastewater,biocide worksheets,wastewater analytical data,facility-wide wastewater audit,cost to pump
and haul current wastewater discharge,metropolitan sewerage district policy on non-contact wastewater,
and current wastewater discharge quality or quantity changes to NCO500608 were conveyed to Mr.
Davidson in a letter from Low&Bonar dated June 26.
Ms. Wiggs conducted a Water Resources Section facility-wide inspection of the Low&Bonar Inc.site on
July 6. During that inspection samples were collected from three sources: Slim Tank,Jarden Steam
Heating Condensate, and the East Ditch. On July 13,Low&Bonar Inc.collected samples from three(3)
additional sources:Manhole 3,Manhole 25,and the Cooper Compressor as well as from one(1)
stormwater source: Poly Cooling Building. The results of those two evaluations were conveyed to the
Water Resources Section in a letter report dated July 25.
The results of a third evaluation,conducted August 2,were conveyed to the Water Resources Section in a
letter-report dated August 31.
The results of a fourth evaluation,conducted October 19,were conveyed to the Water Resources Section
in a letter report dated November 29,
Flow meters were installed Oct 31. Slim Tank meter functional immediately.
System plumbing,equipment installation,and electrical connections completed November 10.
Flood Gate flow meter was functional November 15,
De-chlorination system was installed November 20.
Sampling conducted December 5,
Notice of Intent(NOB application for a General Permit was filed December 18. That application
contained PRELIMINARY analytical values for the December 5 sampling campaign as Table 5. This
report contains the final analytical values from the Pace Labs report dated December 18.
This report describes the results of a sampling and analysis campaign conducted December 5. Samples
were collected from two(2)sources:Slim Tank and the East Ditch(the previous sampling point).
Low&Bonar Inc.—NPDES Discharged Water Report 4 3

CONTACT VS. NON-CONTACT COOLING WATER
Low&Bonar has determined that discharged waters to Hominy Creek are exclusively"non-contact
cooling water","once-through cooling water",condensed water from creature comfort and room cooling
for heat/moisture sensitive electronics equipment,or oil-less air compressor system condensates.
Extruder waters and cooling tower blowdowns are considered"non-contact cooling water", "once.
through cooling water",or permissible discharges respectively. Each Type of discharged water is
discussed in LOW&BONAR's Report 3 dated November 29.
Low&Bonar Inc.—NPDES Discharged Water Report 4 4

DISCHARGED WATER FLOW RATES
Low&.Bonar has continued to refine our process discharge water production evaluations. Table 1 lists
our December 5,measured effluent water contributions—including groundwater—to Low&Bonu's
discharge to an im-named tributary to Hominy Creek.
Three conditions are of note in our calculations:
1. The process wastewater values of maximum discharge were taken from measured discharge
rates during periods of high production,medium to high fall temperatures,and low humidity
during early-December.
2. Groundwater was at a low point;no rainfall events at the facility for the 96 hours preceding
sampling and flow measurements(see Attachment Q.
3. All cooling water streams have been routed through the `Slim Tank' and then through the
`Flood Gate' and hence to Hominy Creek via the East Ditch. This configuration allows all
`non-contact' cooling waters to be sampled from a single point.

FACILITY IMPROVEMENTS
Facilities,Engineering,and Maintenance staff identified several water issues that must be changed to
bring the facility into total compliance with NC Surface Water regulations. These issues and tasks were
ranked described in Report 3 dated November 29.
Low&Bonar Inc.—NPDES Discharged Water Report 4 8

DISCHARGED WATER SAMPLING RESULTS
Table 2 lists the analytical results from samples collected on December 5,2017. The 96 hours prior to
sampling were dry(i.e.,no measurable rainfall). Copies of the site weather station records for October are
included in Attachment D. Table 1 sources and discharges are in the order of flow to Surface Waters. Figure
1 shows the sampling locations. Figure 2 shows how each sampling location is linked in the discharge water
flow to Surface Waters.
Table 2 pollutants in most cases are less than the North Carolina 15A NCAC 02B Surface Water Standards
and Protective Values. Of particular note are the copper and zinc concentrations. Based upon a review of
water treatment chemical Safety Data Sheets and raw materials used at Low&Bonar we conclude that the
sources of copper and zinc are City Water and infrastructure. Our professional judgement is that supplied
City Water in concert with building and water conveyance materials contribute most of these metals to
discharge waters.
Ourjudgement is based in part upon the copper and zinc concentrations of less than(<)0.005 and 0,210
milligrams per liter(mg/L)respectively in City Water within the building. Copper is monitored by the City
of Asheville and their annual report of April 2017 lists a maximum system-wide concentration of 0.005
mg/L.
Although zinc is not addressed in the report, conversations with Mary Grimes of the Asheville Water
Department revealed that distribution system zinc concentrations ranged from 0.20 to 0.17 mg/L on July 28
and October 19 respectively at the North Fork Water Treatment Plant. Thus,it is conceivable that the zinc
concentration in the inlet water is approximately 0.2 mg/L and that concentration is not related to
infrastructure. If so,we should correct all discharge water zinc concentrations by the'background'
concentration of approximately 0.2 mg/L. That correction is not included in this report.
Molybdenum is no longer in discharge waters due to its use as a'tracer chemical' in our water treatment
chemicals supplied by Garrett-Callahan. Our water treatment contractor Garrett-Callahan has modified their
water treatment formulation to not include molybdenum. This and future discharge water analyses should
reflect this change.
Chloroform is in City Water at a concentration of 0.0195 mg/L and in the Slim Tank at a concentration of
0.0087 mg/L. However,chloroform is not detected in any other discharge source. Since there is no Section
2B discharge limit,this is a moot point.
Other pollutants tested are less than State 02B Surface Water Standards or are at concentrations less than the
analytical detection limits.
Figure 1 is a site layout that shows the two(2)December 5 sampling locations. Table 2 addresses only those
pollutants that were detected in the discharge samples in any of the five sampling campaigns. All other
pollutants were reported by the laboratory at"less than the analytical method detection limit". Pace
Laboratories' report is included in Attachment A.
Low&Bonar Inc.-NPDES Dischv'ged Water Report 3 9

SCOPE OF FUTURE TESTING
Low&Bonar Inc.has evaluated its water discharge sources,their pollutants,and volume balances through
five sampling campaigns:July 6,July 13, August 2,October 19,and December 5. We believe that these
evaluations meet the stated expectation of DWR staff;which is to completely characterize discharged water
quality over a range of time and operating conditions. Therefore,we do not expect to conduct additional
sampling campaigns.
The data contained in this and previous reports should serve to form the basis of a discharged water permit
application.
Ultimately,we believe this discussion will lead to a decision that a General Permit is appropriate for Low&
Bonar.
CONCLUSION
Low&Bonar intends to comply with all State and Federal discharge limitations. This fourth report
encompassing five sampling campaigns demonstrates that pollutant concentrations with the exception of
copper and zinc in the current compliance point effluent—the Slim Tank—are below any Division of Water
Resources regulatory limit or North Carolina Surface Water Quality Standards;which are included in
Attachment D.
Please approve Low&Bonar's request to complete a General Permit application for re-issuance of a
National Pollutant Discharge and Elimination System permit.

EXECUTIVE SUMMARY-DISCHARGED WATER STUDY
n
Low&Bonar Inc.has compiled additional information regarding water discharges to surface waters of
the State for review by the North Carolina Department of Environmental Quality's Water Resources
Section. This information comprises a comprehensive water discharge evaluation developed from several
internal staff meetings representing Engineering,Facilities,Maintenance,and Environmental divisions
with our environmental consultant Pisgah Environmental Services.
This report of a sampling and analysis campaign on October 19,2017,is the cumulation of intense study,
discussion,infrastructure changes,equipment changes and repairs,and procedural changes through the
efforts of staff and contractors over the past six months. This report is preceded by three other sampling
and reporting campaigns. Reports of July 5,July 9, and August 2 campaigns were previously reported to
the Water Resources Section.
L&B owns and operates a complex 88-year old facility that has had several ownership changes. One
spin-off industrial manufacturing facility under its own administrative control remains on-site as do 14
tenants. Despite these obstacles,this report is a complete water discharge evaluation of L&B's current
discharged water situation.
This report provides discharge water pollutant concentrations from four(4)sources or intermediate
points. Three of these discharge water sample locations are the same as in all previous campaigns:
Manhole 3,Slim Tank,and the East Ditch. Over the course of all our activities over the last six months
the relative pollutant concentrations at these locations have not substantially changed.
This report includes two important equipment additions at the Slim Tank—the new discharged water
permit compliance point—and the Flood Gate—the new stormwater permit compliance point:
1. Flow Meter Installation in the Slim Tank and the Flood Gate.
2. D�Chlorination System Installation in the Slim Tank.
This report—as with three previous reports—demonstrates that water discharges from the Low&Bonar
Inc.facility substantially comply with North Carolina 15A NCAC 02B Surface Water Standards and
Protective Values. Exceptions to this statement are addressed below.
1. Two metals—copper and zinc—are discharged at values exceeding regulatory limits.
Copper and zinc concentrations in the new discharge compliance point(i.e., Slim Tank)are at
concentrations of 0.0381 and 0.561 milligrams per liter(mg/L)respectively;the acute regulatory
limits are 0.0036 and 0.036 mg/L respectively. Of note are that City Water copper and zinc
concentrations of North Fork reservoir water are 0.0076 and 0.210 mg/L,respectively, Thus, City
Water supplied to L&B exceeds the State regulatory discharge limits.
!i Both copper and zinc are considered to have water system supply and infrastructure sources
!i rather than process sources.
Another metal—molybdenum—was previously discharged from the facility. Molybdenum's only
source was a water treatment chemical used in the Cooling Towers. Our water treatment supplier
of this chemical used molybdenum as a tracer(i.e.,as molybdenum concentration values decrease
the supplier adds more of the entire formulation). The water treatment chemical supplier has
removed molybdenum from this formulation.
U
Low&Bonar Inc.—NPDES Discharged Water Report 3 1

2. Totalizing flow meters were installed in the Slim Tank and in the Flood Gate on October 31;i.e.,
since the October 19 sampling campaign. The metered flow data confirm that significant
l i discharge reductions have been realized from recent equipment changes to the 21 extruder
cooling water points,seven(7)cooling towers,and 10 boiler condensate receivers.
Discharge water flow rates in this report are based upon flow meter averages over the first two
weeks of operation. These values differ from direct measurements on October 19;which vary
greatly on a minute-to-minute basis and daily.
The first two weeks of flow monitoring show that our previously reported flow rate calculations
were generally correct. Thus,the totalizer flow rates are used in calculating mass pollutant
effluent rates. In the future,totalizer flows may also be used for Wasteload Allocation
calculations if necessary.
3. Total Residual Chlorine is discharged from multiple sources;some are once-through cooling
waters that discharge essentially City Water(e.g.,extruders),most are cooling tower blowdowns,
and some are boiler condensates. Note that City Water—which is used in all three processes—
Total Residual Chlorine concentration averages about 1.4 milligrams per liter(mg/L).
Prior to installation of the de-chlorination system,Total Residual Chlorine concentrations in the
new discharge compliance point(i.e, Slim Tank)ranged from 0.4 to 0.8 milligrams per liter
(mg/L);the regulatory limit is 0.017 mg/L.
r,, Recently,after installation of the de-chlorination system,Total Residual Chlorine at the Slim
Tank and Flood gate compliance points has been at concentrations of less than 0.017 mg/L at
both points(see Figure 2 for sampling locations).
—� Our conclusion is that Low&Bonar Inc.is in compliance with the Total Residual Chlorine
standard in the Slim Tank;which is an internal sampling point that is being proposed as the new
"compliance point".
4. Boiler steam condensate water was discharged from several receivers and condensate drip legs to
the stormwater collection/discharge system. Boiler condensates have now all been returned to the
boiler(i.e.,recycled)or rerouted to MSD.
The net result was that Total Residual Chlorine mass effluent rate was significantly reduced by
changes to the extruders,cooling towers,and the boiler system that reduced their discharges.
Now that the de-chlorination system is operational Total Residual Chlorine concentrations have
dropped to less than the analytical detection limit.
5. With reductions of water discharged from the Cooling Towers,Extruders,and Boiler
Condensates the amount of purchased City Water has decreased. See purchased water records in
Attachment D. _

CHRONOLOGY
(7, On May 22,2017,Low&Bonar Inc.conducted a Low&Bonar-facility-wide requested inspection with
North Carolina Department of Environmental Quality staff conceming compliance with stormwater
regulations.
During that inspection,several other discharged water issues arose. As a follow-up to that inspection Ms.
Linda Wiggs of the Division of Water Resources sent to Low&Bonar Inc. in a June 12 email an
Information Request for water discharge sources,rates,and pollutant concentrations. A response to DWR
from Low&Bonar was dated June 15.
On June 19,the Water Resources Section issued a Notice of Violation and Intent to Assess Civil Penalty
(NOV-2017-DV-0148,Incident No.: 201701034)to Low&Bonar Inc.
Low&Bonar Inc. attended a meeting with Water Resources Section staff on June 23. During that
meeting Water Resources Section staff clarified the scope of Ms. Wiggs' requested information and Mr.
Landon Davidson identified other tasks in an Information Request dated June 23. Those data,including
estimates of the volume of wastewater discharged daily,list of biocides and any other additives in
wastewater,biocide worksheets,wastewater analytical data,facility-wide wastewater audit,cost to pump
and haul current wastewater discharge,metropolitan sewerage district policy on non-contact wastewater,
and current wastewater discharge quality or quantity changes to NCG500608 were conveyed to Mr.
Davidson in a letter from Low&Bonar dated June 26.
Ms.Wiggs conducted a Water Resources Section facility-wide inspection of the Low&Bonar Inc.site on
July 6. During that inspection samples were collected from three sources: Slim Tank,Jarden Steam
Heating Condensate,and the East Ditch. On July 13,Low&Bonar Inc. collected samples from three(3)
additional sources:Manhole 3,Manhole 25,and the Cooper Compressor as well as from one(1)
stormwater source:Poly Cooling Building. The results of those two evaluations were conveyed to the
C. � Water Resources Section in a letter report dated July 25.
The results of third evaluation,conducted August 2,were conveyed to the Water Resources Section in a
letter report dated August 31.
This report describes the results of a sampling and analysis campaign conducted October 19. Samples
were collected from four(4)sources:Manhole 3,Slim Tank,Floodgate(new sto rnwater sampling point),
and the East Ditch(previous discharged water sampling point).
Flow meters installed Oct 31. Slim Tank meter functional immediately.
System plumbing,equipment installation,and electrical connections completed November 10.
Flood Gate flow meter functional November I5.
De-chlorination system installed November 20.

CONTACT VS. NON-CONTACT COOLING WATER
o L&B has determined that discharged waters to Hominy Creek are exclusively"non-contact cooling
water","once-through cooling water",condensed water from creature comfort and room cooling for
heat/moisture sensitive electronics equipment,or oil-less air compressor system condensates. Extruder
waters,cooling tower blowdowns,and boiler condensates are all considered"non-contact cooling water",
"once-through cooling water",or permissible discharges respectively. Each type of discharged water is
discussed below.
Cooling Water
L&B extruders and cooling towers are examples of"non-contact cooling water"or"once-through cooling
water". For example,City Water is piped through an extruder head or gear box to indirectly cool the
mechanism or to prevent the product from becoming too but. This is a type of non-contact cooling water.
Specifically,water used in cooling the extruder throat and gear boxes is 'once-through cooling water'.
Residual chlorine content of both processes is equal to that of City Water and other chemical
characteristics are the same. Thus,extruder and cooling tower waters impart chlorine to discharged
waters. L&B has installed a dechlorination system to address residual chlorine. This is discussed in a
later section.
Boiler Condensates
Condensates from boiler steam are classified as non-process water. These waters do not contain the
inorganic components of boiler treatment chemicals, but they do contain chlorine.
The decision to recycle boiler condensates rather than discharge them is more an economic decision than
an environmental decision. L&B calculates that every 100 gallons of boiler condensates discharged daily
� \ costs$456 per year.
Air Condensates
Condensates from compressed air systems are classified as non-process water. Although compressed air
is used,for example,to move thread through tubing or to spread thread on the Fleecing table,the
condensed water that remains in the pressurized lines is never in contact with product(s)or raw materials.
Moreover,this air is produced by`oil-less"compressors;thus,no oil can be in condensed water.
Therefore,condensate from these lines is considered"non-contact"and is permitted to be discharged to
surface waters.Compressed air system water is directed to the Slim Tank and hence to Hominy Creek.
Air handling units(AHUs)create condensates from atmospheric vapor. This is considered non-contact
water(i.e.,does not contact product).
Process Condensates
One type of AHU air does contact products. In this evaluation,yarn quench and room cooling air
condensates were classified as"process water". For example,quenching the recently formed yarn strands
with cool air releases nylon or PET monomers to room air. This air is then mixed with room cooling air.
Although these monomers are not in concentrations to be detected as total suspended solids they are still
"process water". Consequently,these waters were replumbed to MSD.
L&B identified several true"contact"process water discharges and has routed them all to the
Metropolitan Sewerage District(MSD)of Buncombe County sewerage system. These sources include:
• Die Oven cleaning
• Maintenance wash sinks(other than solvent parts washers)
Low&Bonar Inc.—NPDES Discharged Water Report 3 4

• Laboratory water
GROUNDWATER
Groundwater as Cooling Were
Instead of using City Water in cooling towers and to cool extruders,L&B explored using ground water
stored in three large flooded ventilation tubes under the Fleecing Department floor to either cool the water
circulated through these systems or as the cooling water itself The benefit of this option is that it would
only require the purchase of a pump and installation of some piping. Several un-used heat exchangers
around the plant are available to be put into service for this application.
To test this option the flooded ventilation system was pumped to MSD—with their permission—at a rate
of about 44,000 gallons per day(gal/d)for about four(4)hours—a total of 7,890 gallons. This rate is
approximately the overall groundwater infiltration rate from the site into all the stormwater piping
discharge at the East Ditch. The water level in the ventilation system dropped by 4.59 inches. Thus,the
pumping rate exceeded the recharge rate.
The next day,on October 5,we pumped about 3,210 gallons from the ventilation system over six(6)
hours. This rate—12,845 gal/d(8.92 gal/min)—is approximately the amount necessary to replace City
Water that cools the 21 extruders. The water level in the ventilation system dropped by 1.31 inches.
Again,the pumping rate exceeded the recharge rate.
Note that these results are an evaluation of groundwater at a moderately low level. In the preceding 20
days prior to testing the site had received 0.3 inches of rain in a single event. Thus, this is not even close
to the most severe drought conditions the region has experienced over the past five years. So,unless the
r \ site is experiencing almost flood conditions,there is no[enough wet rent ine the flooded ventilation
/ shafts to supply process cooling water or to act as a heat sink for process cooling.
Ultimately,we conclude that the groundwater recharge rate in the flooded ventilation shaft is not
sufficient to replace even the smallest cooling water consumer of City Water in the entire facility.
Groundwater as a Heat Sink
During our examination of using ventilation shaft water for direct cooling we considered it for indirect
cooling. In this treatment scenario extruder cooling water would be pumped through heat exchangers that
use ventilation shaft water as a cooling agent.
Since ventilation shaft water is not recharged quickly it was determined that the transferred heat would
buildup in the water. Ultimately,the ventilation shaft water would attain the same temperature as the
extruder water it was intended to cool. Therefore,this option was abandoned.

r^ DISCHARGED WATER FLOW RATES
1, L&B has continued to refine our process discharge water production evaluations. Table 1 lists our current
measured discharge water contributions—including groundwater—to L&B's discharge to Hominy Creek.
The new totalizing flow meters in the discharge water system(see Exhibits 9 and 11)are dynamic
calculations;measured water flows are five-minute averages that are averaged into hourly values. These
flows vary throughout the day depending on work load,temperature,humidity,and a host of other
production factors. For example,during our August 2 sampling campaign discharge water flows from
only the extruders into the Slim Tank varied by a factor of three(3)over a 20-minute period. Other
inputs to the Slim Tank varied as well.
Calculations of Groundwater Infiltration also vary due to rainfall amounts at the site and upstream in the
Hominy Creek drainage. These factors are beyond our control. However,with metered discharge water
data we are able to evaluate Groundwater Infiltration more accurately.
Three conditions are of note in our calculations:
1. The process wastewater values of maximum discharge were taken from measured discharge
rates during periods of high production,medium to high fall temperatures,and low humidity
during mid-October.
2. Groundwater was at a low point;no rainfall events at the facility for the 96 hours preceding
sampling and flow measurements(see Attachment D).
3. All cooling water streams have been routed through the`Slim Tank' and then through the
`Flood Gate' and hence to Hominy Creek via the East Ditch. This configuration allows all

Groundwater infiltration into the combined discharge water/stormwater system is calculated by the
difference between the flow through the Flood Gate and contributions from Process Cooling Water and
Pumped Groundwater from Phan, We calculate that 37 percent of the discharged water through the
Flood Gate is groundwater infiltration.
The infiltration rate relates to the length of concrete piping installed below the groundwater table.
Approximately 2,340 feet of main trunk stormwater lines lie below the groundwater table in addition to
the relatively shallow ollection lines from roof drains and surface level drop inlets that are above the
groundwater table Fi ure 2 hows all the stotmwater lines but the differences between those below
groundwater table and s tcial collection lines is not delineated. Figure 1 shows the approximately 772
linear feet of deeper,main trunk stormwater lines between the Slim Tank and the Flood Gate.
Approximately 1,560 linear feet of additional submerged stormwater piping is upstream of the Slim Tank.

FACILITY IMPROVEMENTS
�. Facilities,Engineering,and Maintenance staff identified several water issues that must be changed to
bring the facility into total compliance with NC Surface Water regulations. These issues and tasks were
ranked by:
1. Impact on surface water quality,
2. Schedule to completion,
3. Availability of motors and pumps,and
4. Availability of L&B staff or contract staffing.
First among issues was to return all treated and heated boiler condensates to the boiler system. Losing
boiler condensate to the East Ditch or to MSD is a waste of water treatment chemicals,heat energy,and
purchased water.
Low&Boom Inc.has installed or performed the actions described in the previous sections. Table 2 is a
summary of the equipment and labor costs as of November 1. Note: The list does not include costs for
completion of the permit application and ancillary evaluations."Punch Lists"of identified tasks to bring
discharge water into compliance are listed in seven(7)weekly reports in Attachment C.
The following sections describe actions L&B has embarked upon to minimize impacts to surface waters.
BOILER CONDENSATE
Over the years the L&B Boiler Condensate System has developed many connections and discharges to
/- the stormwater system that flows to Hominy Creek via the East Ditch or to the Metropolitan Sewerage
i District(MSD)system. Neither discharge reflects the condensate system's initial design. The Boiler
Condensate System was designed to capture and recycle all boiler steam condensate. To this end 10
condensate receivers were installed around the facility.
The system was originally designed to work in the following manner: Boiler steam condenses in transfer
piping and flows via gravity to a receiver. These receivers store the condensate until the container is full
and then pump the liquid to a height that allows it to flow by gravity to the boiler condensate storage in
the boiler room. The condensate is heated again in the boiler and the process repeats.
In order to repair/replumb and once again capture and recycle all boiler steam condensates,the following
tasks have been completed:
I. Repaired or replaced cooling tower pumps,motors,floats,and switches(see Table 2).
2. Removed all boiler steam receiver and drip line piping connections to MSD or to the
stormwater system(see Table 2)and Exhibits 4 and 5.
3. Installed bypass piping upstream of receivers for maintenance activities(see Exhibit 3).
4. Fabricated two wheeled metal tanks to collect boiler condensates during maintenance
activities. Tank contents will be returned to the boiler condensate.system or to MSD via a
dedicated drain. —The pace of work involved can be followed in the "Punch Lists" included in Attachment C.
` These lists contain completion dates for specific tasks. `.,..,._...._.

Low&Boner Inc.—NPDES Discharged Water Report 3 8

CHILLER COOLING TOWER 058 SYSTEM
Replaced two Chiller Room Cooling Tower 0-58 water pumps and motors(see Exhibit 13). Re-attached the
effluent line to the central discharge point—the Slim Tank—in the DowTherm room. This repair re-routed
the Chiller Cooling Tower owdpwn to the stormwater collection system via the Slim Tank rather than
. t�iractty touter collection system. -------
This change was necessary to have all stormwater collection system discharges from a single point. Having
a single point for flow monitoring and sampling is necessary to demonstrate compliance with permit
conditions. It also provides a single location for dechlorination.
A purchase order for a replace pump/motor is included in Attachment C.
COOPER COOLING TOWER SYSTEM
Replaced two Cooper Cooling Tower water pumps and motors. Re-attached the effluent line to the piping
system to the Slim Tank central discharge point in the DowTherm room. This repair re-routed the Cooper
Cooling Tower blowdown to the stormwater collection system via the Slim Tank rather than directly to the
stormwater collection system. Again,this change was necessary to have a stormwater collection system
discharges and dechlorination are conducted from a single point.
COMPRESSOR COOLING TOWER 054 SYSTEM
Replaced two float valves.
A purchase order for a float valve is included in Attachment C.
SLIM TANK—NEW COMPLIANCE POINT
.J Replumbed the central discharge point-the Slim Tank-in the DowTherm room so that all inputs are on the
upstream side of the weir(see Exhibit 11). [Two lines were moved about 3 feet upstream.] In this report and
in the future,all permit compliance monitoring for water discharged to Hominy Creek via the East Ditch will
be conducted at the Slim Tank discharge point.
.ROOF STORMWATER DRAIN PIPING
Low&Bonar Inc.replumbed the stormwater drain system in the main processing areas—all six(6)levels of
the tower,winding,fleecing,Enkamat, and Colback—so that drains contain only rain water and condensates
from creature comfort cooling—NO PROCESS WATER. Abandoned lines have been spray painted orange
and tags attached to direct our contractor to"cut and cap"all the marked lines(see Exhibits 4 and 5).
FLOW METERS
Low&Bonar Inc. installed discharged water flow monitors in the follow locations:
o Central water discharge point—the Slim Tank—in the DowTherm room(see Exhibit 11).
.J o Flood gate directly upstream of the head of the East Ditch(see Exhibits 8,9,and 10).
Flow meters record discharge water flow rates every 15 seconds and then compute hourly and daily totals.
Ultimately, the two flow meters compute monthly discharged water flows.
The flow meter vendor initially installed a 30-inch Cipoletti weir in the Flood Gate exit. This flow device is
too large for the volume of water going through the Flood Gate;the readings by the flow sensor ranged from
about 0.05 to 0.10 inches. This range is too small for the sensor to accurately measure. Therefore,L&B
j installed a,60 de g_ ed V-nh_wVjr on top of the Cipoletti weir. This weir generates readings by the flow
sensor rangi re �
ng from 3 to 5 inches;which is easily in the capacity of the sensor to monitor. L&B plans to
Low&Boom Inc.—NPDES Discharged Water Report 3 9

{
permanently install a 60-degree V-notch weir in this location after enough flow data is generated to file a
pe7miTappp1icatiom.
Attachment E contains the schematics and operational manuals for the flow sensors.
Table 1 lists PRELIMINARY discharged water flows from the two monitoring points from October 31 to
November 7. During the period October I I to November 13 L&B purchased—on average—98,645 gal/day.
These data indicate that discharged water is 15.8 percent of the water purchased over the same period.
Attachment D contains the purchased water volumes over the same period.
Moreover, the PRELIMINARY purchased from July 12 to August 10 was 155,093 gal/day. During that time
discharged water was 35.6 percent of purchased water. Thus,PRELIMINARY CALCULATIONS of water
reductions from our replumbing actions and cooling water use indicate that L&B has reduced its water use
significantly. Water purchasing records and water discharge records over the next several months will
provide more statistically significant data.
DECHLORINATION SYSTEM
Low&Bonar installed a dechlorination system in the Slim Tank and a Secondary Tank. All chlorinated
water used in the extruders and the seven(7)cooling towers flows through these two tanks. Figure 2 is a
process flow diagram of the dechlorination system. Exhibit 12 is an image of the instrumentation
installation.

The L&B water chemical supplier,Garrett-Callahan,estimates that on a daily average the dechlorination
system wilt consume about 1.47 pounds of their Formula 6600 sodium bisulfite solution. This amount is
based upon previous daily discharges of up to 55,000 gal/d. Since the discharged water has been reduced to
about 15,500 gal/d,the dose rate should be reduced to about 0.41 Ib/d. A Safety Data Sheet for Formula
6600 is included in Attachment F.

DISCHARGED WATER SAMPLING RESULTS
l Table 3 lists the analytical results from samples collected on October 19,2017. The 96 hours prior to
sampling were dry(i.e,no measurable rainfall). Copies of the site weather station records for October are
included in Attachment D. Table 3 sources and discharges are in the order of flow to Surface Waters. Figure
1 shows the sampling locations. Figure 2 shows how each sampling location is linked in the discharge water
flow to Surface Waters.Tables 4 and 5 are discharged water results from the July 6 and 14 campaigns and
the August 2 campaign respectively. These latter two tables are included for perspective.
Table 3 pollutants in most cases are less than the North Carolina 15A NCAC 02B Surface Water Standards
and Protective Values. Of particular note are the copper and zinc concentrations. Based upon a review of
water treatment chemical Safety Data Sheets and raw materials used at L&B we conclude that the source of
copper and zinc are from City Water and infrastructure. Our professional judgement is that supplied City
Water in concert with building and water conveyance materials contribute most of these metals to discharge
waters.
Ourjudgement is based in part upon the copper and zinc concentrations of less than(<)0.005 and 0.210
milligrams per liter(mg/L)respectively in City Water within the building. Copper is monitored by the City
of Asheville and their annual report of April 2017lists a maximum system-wide concentration of 0.005
mg/L. Although zinc is not addressed in the report,conversations with Mary Grimes of the Asheville Water
Department revealed that distribution system zinc concentrations ranged from 0.20 to 0.17 mg/L on July 28
and October 19 respectively at the North Fork Water Treatment Plant. Thus,it is conceivable that the zinc
concentration in the inlet water is 0.210 milligrams per liter and that concentration is not related to
infrastructure. If so,we should correct all discharge water zinc concentrations by the`background'
concentration of approximately 0.20 mg/L, That correction is not included in this report.
Molybdenum is no longer in discharge waters due to its use as a`tracer chemical' in our water treatment
( chemicals supplied by Garrett-Callahan. Our water treatment contractor Garrett-Callahan has modified their
`- water treatment formulation to not include molybdenum. This and future discharge water analyses should
reflect this change.
Chloroform is in City Water at a concentration of 0.0195 mg/L and in Manhole 3 and the Slim Tank at
concentrations of 0.0021 and 0.0052 mg/L respectively. However, chloroform is not detected in any other
discharge source.
Other pollutants tested are less than State 02B Surface Water Standards or are at concentrations less than the
analytical detection limits.
Figure 2 is a site layout that shows the four(4)October 19 sampling locations. Tables 3,4,and 5 address
only those pollutants that were detected in any of the four discharge samples. All other pollutants were
reported by the laboratory at"less than the analytical method detection limit". Pace Laboratories' report is
included in Attachment A.
Table 3 lists pollutant discharge rates from the new compliance point(i.e,the Slim Tank in the DowTherm
Room),the new stormwater sampling point(i.e.,Flood Gate at head of East Ditch),and the previous
compliance point(i.e.,the East Ditch)(see Figure 2). These discharge rates demonstrate that—considering
instantaneous flow variations—the Slim Tank discharge rates are in the same concentration range as the
other two points.
�J
Low&Bonar Inc.—NPDES Discharged Water Report 3 12

SCOPE OF FUTURE TESTING
Low&Bonar Inc.has evaluated its water discharge sources,their pollutants,and volume balances through
four sampling campaigns: July 6,July 13,August 2,and October 19. We believe that these evaluations meet
the stated expectations of DWR staff; which is to completely characterize discharged water quality over a
range of time and operating conditions. Therefore,we do not expect to conduct additional sampling
campaigns.
The data contained in this report should serve to form the basis of a discharged water permit application.
Ultimately,we believe this discussion will lead to a decision that a General Permit is appropriate for Low&
Bonar.
CONCLUSION
Low&Bonar intends to comply with all State and Federal discharge limitations. This third report—
encompassing four sampling campaigns—demonstrates that pollutant concentrations in the current
compliance point effluent—the Slim Tank—are below any Division of Water Resources regulatory limit or
North Carolina Surface Water Quality Standards;which are included in Attachment G.
Please approve Low&Bonar's request to complete a General Permit application for re-issuance of a
National Pollutant Discharge and Elimination System permit.
