1. INTRODUCTION
Novozymes North America, Inc. (Novozymes) has applied for a National Pollutant Discharge Elimination System
(NPDES) permit for direct discharge of wastewater from its manufacturing facility located in Franklinton, North
Carolina. Novozymes is seeking a NPDES discharge to Cedar Creek, a tributary to the Tar River located in the Tar -
Pamlico River Basin. Currently, Novozymes discharges all process wastewater from the facility by one of two
methods: (1) land application on agricultural fields pursuant to Non -Discharge Permit (WQ00028o6) (Appendix A),
and (2) indirect discharge to the Franklin County Wastewater Treatment Plant (WWTP) pursuant to Industrial User
Pretreatment (IUP) Permit 0112 (Appendix B).
Novozymes applied for the NPDES permit to comply with the provisions of the Corrective Action Plan for the North
Carolina Department of Environmental Quality (NCDEQ) Division of Water Quality (Division) Incident Number
86545 that was conditionally approved by the Division Director on January 31, 2017 (Appendix C). Per the
requirements of the approved Corrective Action Plan, Novozymes must reduce land application rates of treated
wastewater from 30 inches/yr to 8.5 inches per year and also must recover and treat approximately go,000 gpd of
groundwater. The Division's approval of the Corrective Action Plan requires Novozymes to obtain the NPDES permit
to satisfy these requirements (Appendix C). Additionally, the NPDES permit will allow Novozymes to establish a fully
conjunctive wastewater system and increase operational flexibility by giving it three methods for disposing of
wastewater: (1) land application on nearby farm fields, (2) discharge to the Franklin County WWTP, and (3) direct
discharge to surface water. Last, Novozymes would like to expand the facility, increase production capacity, and add
manufacturing jobs in a rural community. Expansion of the facility will require significant additional discharge
capacity that would be provided by the NPDES permit.
A revised NPDES permit application, which included an updated Engineering Alternatives Analysis (EAA), was
submitted to the North Carolina Division of Environmental Quality (DEQ) Division of Water Resources (Division) on
11/3o/18. The NPDES application requested tiered flow limits for i.o,1.5 and 2.0 million gallons per day (MGD).
Cedar Creek is located in the Tar -Pamlico River Basin and is classified as a nutrient sensitive water (NSW) pursuant
to North Carolina Administrative Code Section i5A NCAC 02B.0223. Due to the discharge location is in the Tar -
Pamlico River Basin and as discussed in correspondence from the Division dated December 14, 201.6 (Appendix D),
the Division requested that Novozymes prepare and submit a Best Available Technology Economically Achievable
(BAT) analysis to assist in establishing permit limits for total phosphorus (TP) and total nitrogen (TN). The following
report presents that BAT analysis and proposes permit limits for TP and TN based on treatability testing, available
treatment technology, and equivalent annual costs. BAT Economically Achievable limits represent, in general, the
best existing performance of treatment technologies that are economically achievable within an industrial point
source category. (See EPA NPDES Permit Writers' Manual, 20io, EPA-833-K-io-ooi). The BAT analysis described
below was conducted pursuant to the protocol specifically agreed upon with the Division and as outlined in
correspondence dated September 7, 2018 (Appendix E).
To establish and support proposed BAT TN limits for the proposed Novozymes NPDES permit, three (3) treatment
technologies were evaluated based on treatability testing, and the capital and annual recurring operational costs to
remove nitrogen were compared amongst each technology evaluated.
A review of historical operating and technology performance data was performed to establish and support the BAT TP
limit for the proposed Novozymes NPDES permit.

2. INDUSTRIAL PROCESS DESCRIPTION
2.1 Facility Description
At Novozymes, industrial enzymes are produced using a process called submerged fermentation. This involves
growing carefully selected microorganisms (bacteria and fungi) in closed vessels containing a rich broth of nutrients.
As the microorganisms break down the nutrients, they produce the desired enzymes. The fermentation process
requires nutrients based on renewable raw materials like corn starch, sugars, and soy grits.
The first step in harvesting enzymes from fermentation medium is to remove insoluble products, primarily microbial
cells. This is normally done by centrifugation or microfiltration steps. As most industrial enzymes are extracellular —
secreted by cells into the external environment — they remain in the fermented broth after the biomass has been
removed. The spent biomass can be recycled as a fertilizer on local farms, as is done under a residuals disposal permit
at Novozymes' Franklinton site. The enzymes in the remaining broth are then concentrated by evaporation,
membrane filtration or crystallization depending on their intended application. Certain applications require solid
enzyme products, so the crude enzyme is processed into granules for convenient dust -free use. The wastewater
discharge at Novozymes consists of discharge from the fermentation and recovery production processes and from site
utilities such as cooling tower and boiler blowdown. From the facility, the waste streams are characterized into two
groups: permeate (e.g. filtrate produced from the membrane filtration step) and non -permeate (e.g. all other waste
streams). Both the permeate and non -permeate waste streams are treated onsite at the Franklinton facility at
Novozymes' WWTP.
Based on Novozymes' SIC Code 2869, the facility's industrial discharge is regulated under the Organic Chemicals,
Plastics, and Synthetic Fibers (OCPSF) effluent limits for Subcategory G Bulk Organic Chemicals (40 CFR 414.70).
However, Novozymes' manufacturing process is a fermentation process, and 40 CFR 414.1i(e) states the provisions of
40 CFR 414 do not apply to discharges from the manufacture of organic chemical compounds solely by fermentation
processes. It should be noted that even if the provisions of 40 CFR 414 did apply to the Novozymes facility, BAT
limits are not established in 40 CFR 414 Subcategory G for nitrogen.
2.2 Wastewater Treatment and Discharge Permits
Novozymes employs onsite wastewater treatment prior to discharge. Over the past decade, Novozymes has
historically operated its treatment facility in two different modes of operation. From 2010-2014, Novozymes used a
multi -stage activated sludge process consisting of moving bed biological reactors (MBBRs) with high chemical oxygen
demand (COD) loading followed by an extended aeration lagoon for COD removal, nitrification and denitrification
(see Section 3, Figure 1). The extended aeration system used was the Biolac® lagoon aeration system that provides
automatic dissolved oxygen and aeration control to create multiple oxic and anoxic zones in a single treatment basin,
eliminating the need for separate anoxic mixers and MLSS recycle flow and pumps.
In 2015, Novozymes installed an anaerobic treatment system upstream of the MBBRs (See Section 3, Figure 2). The
primary project driver was to improve sustainability metrics at the wastewater plant by reducing energy consumption
and sludge generation. This process modification resulted in a reduced capacity to treat nitrogen compared to the
previous configuration, but also reduced the amount of biosolids produced. The MBBRs were converted to
nitrification and denitrification polishing tanks with supplemental carbon addition. The existing Biolac lagoon
system is still utilized when additional COD reduction or nitrification is required. For reference, a more detailed
Dewberry Novozymes North America, Inc. I Best Available Technology Analysis 17

discussion of the existing treatment system configuration is provided in Section 3 below, and an existing WWTP site
layout is presented in Appendix F.
Novozymes currently discharges treated wastewater via two discharge permits: (1) land application through Non -
Discharge Permit (WQ00028o6), and (2) indirect discharge to the Franklin County WWTP via IUP Permit 0112. IUP
Permit 0112 was issued by Franklin County, effective November 14, 2018. The table below summarizes the effluent
parameters listed in the IUP with numerical limits.

Novozymes has also been re -issued a Non -Discharge Wastewater Irrigation System Permit by the Division, effective
date of June 8, 2017 for land application of 30 inches per year. Novozymes prepared a Corrective Action Plan
conditionally approved by the Division on January 31, 2017 (Appendix C) requiring Novozymes to reduce its land
application rate from 30 in/yr to 8.5 in/yr after the receipt of a NPDES permit and after construction and
commissioning of their upgraded treatment process and approved NPDES discharge.
The Corrective Action Plan as approved by the Division requires the NPDES discharge permit. The NPDES permit
will allow Novozymes to establish a fully conjunctive wastewater system and increase operational flexibility by giving
it three methods for disposing of wastewater: (1) land application on nearby farm fields, (2) discharge to the Franklin
County WWTP, and (3) direct discharge to surface water. Last, Novozymes would like to expand the facility, increase
production capacity, and add manufacturing jobs in a rural community. Expansion of the facility will require
significant additional discharge capacity that would be provided by the NPDES permit

3.2 2010 — 2014 WWTP Operation
From 2010-2014, the Novozymes WWTP configuration (Figure 1) included a primary clarifier, followed by biological
treatment, clarification, and dissolved air floatation (DAF) for phosphorous removal. The primary clarifier is 35-ft in
diameter, and treats non -permeate based waste streams for solids and grit removal. Biological treatment for organics
and nitrogen was accomplished in two 240,000 gallon aerobic reactors (To2 and Toi), which operated in series as
MBBRs. Effluent from Toi was discharged to an in -ground treatment lagoon with an effective volume of 1.94 million
gallons (MG). The lagoon was equipped with a Biolac® aeration system. An internal recycle pump station was used
to recycle nitrate from the effluent end of the lagoon to the influent end. The Biolac® system was cycled on/off via
timers to create anoxic "zones".
Sludge was returned from the secondary clarifier to both the lagoon anoxic reactor zone and T02. Clarifier effluent
was either discharged to the effluent storage system prior to land application or to the DAF system for phosphorous
removal prior to discharge to the Franklin County WWTP. Novozymes has a 52 MG effluent storage lagoon located
onsite for land application.

Historical data from this period is provided in Appendix G and is summarized by monthly averages for flow, COD,
VSS, nitrate/nitrite (NO3/NO2), ammonia (NH3), total Kjehldahl nitrogen (TKN), and total suspended solids (TSS)
parameters.
The lagoon configuration presented some process challenges. For example, the mixed liquor biomass exhibited
tendency to settle within the lagoon when the Biolac® laterals were cycled off resulting in mass transfer limitations
and reduced treatment capacity within the anoxic zone. Furthermore, the lagoon is shallow (<io feet) and the oxygen
requirements often exceeded the supply capacity of the Biolac® system. These low DO conditions impacted the rate
of nitrification.
3.3 2015 to Present WWTP Operation
Novozymes currently operates under the treatment configuration depicted in Figure 2 below. As previously stated
above, the addition of the anaerobic treatment system reduced WWTP energy consumption and sludge generation,
but also reduced the capacity of the WWTP to remove nitrogen compounds. A summary of historical Novozymes
effluent data from January 2015 to October 2018 is presented in Appendix H. The data listed in Appendix H was
calculated from historical monthly data after tertiary (DAF) treatment.

3.4 Historical WWTP Performance
Table 3.2 provides a summary of Novozymes' WWTP effluent operating data from the 2010-2018 historical data set
provided as Appendices G and H. The table lists the calculated average and maximum monthly average effluent
concentrations from reported daily and monthly data contained in the historical data set for COD, TP, TN, TKN, NH3
and NO3/NO2. The values are separated into two sections: before the implementation of the anaerobic system (2oio-
2014) and after the anaerobic system was brought online (2015-2018).

"Data presented in this table represents the average and maximum of average monthly effluent values from Novozymes effluent data
shown in Appendices G and H.
For the period of 2010-2014, the TN and TP effluent concentrations discharged from the Novozymes' WWTP
averaged 15 mg/l and 2.2 mg/l respectively. For the most recent period following installation of the anaerobic system
(2015 — 2018), effluent TN concentration increased to 19 mg/L, and the effluent TP concentration decreased to 1.4
mg/l. It should be noted that the influent TN and TP average 208 mg/l and 90 mg/l, respectively (Table 3.1), which
translates to >go% TN removal and >98% TP removal. For both periods, the average ammonia concentrations
achieved were less than 3.0 mg/l, indicating significant nitrification was occurring. The nitrate/nitrite concentration
increased from 5.8 mg/l to io mg/l following the anaerobic system installation. This indicates reduced denitrification
efficiency.
Although the current treatment processes provide partial nutrient removal, enhanced nitrogen removal was not
targeted, as Novozymes' effluent permit limitations did not require this level of treatment. The historical IUP TN and
TP limits are summarized in the table below.
As shown below, from IUP inception through August 2o16, Novozymes was not subject to TN limits, and the
concentration limits for ammonia ranged from 48 mg/l to 5 mg/l. TP limits for that same period ranged from 18 mg/l
to 5 mg/l to a mass based limit. For land application, per Novozymes' Non -Discharge Permit, treated wastewater is
land applied at agronomic loading rates but the permit does not contain numerical limits for TN or TP (Appendix A).

4. TN TREATMENT TECHNOLOGY ALTERNATIVES EVALUATED
4.1 TN Treatment Technologies
Three (3) treatment technologies were evaluated to identify the BAT Economically Achievable limits for TN, which in
general represent the best existing performance of treatment technologies that are economically achievable within an
industrial point source category (EPA NPDES Permit Writers' Manual, 201o, EPA-833-K-io-ooi). The three (3)
treatment processes evaluated were simultaneous nitrification and denitrification (SND) processes in the following
continuous activated sludge configurations: extended aeration, conventional aeration, and high -rate aeration. SND
continuous flow activated treatment facilities operate at lower DO concentrations (0.50f0.2 mg/l on average), and
are able to achieve nitrification and denitrification in the same bioreactor tank. Recent studies have presented data
demonstrating over go% COD removal, and at increased carbon to nitrogen (C/N) ratios, nitrogen removal
efficiencies higher than 98% SND'.
The three technologies evaluated as part of the BAT analysis are best defined and differentiated by their food -to -
microorganism (F:M) ratios. The F:M ratio is a significant design and operational parameter of activated sludge
systems. The three technologies evaluated include extended aeration, conventional aeration, and high -rate aeration.
These three technologies typically are designed with the following F:M ratios:
• Extended Aeration, 0.05 < F:M < 0.15, (units of mg COD/mg MLVSS*day)
• Conventional Aeration, 0.25 < F:M < o.6o
• High Rate Aeration, 0.50 < F:M < 1.5
Novozymes has successfully operated high rate aeration, SND continuous flow WWTPs at its Kalunborg, Denmark
and Tianjin Shi, China facilities. The WWTPs at Kalunborg and Tianjin Shi achieve SND using automated DO control
based on feedback from nitrate and ammonia sensors installed within biological reactor trains.
The facility in China has successfully operated for the last 20 years. The WWTP there includes reactors which are
continuous flow that cycle and control aeration based on ammonia and nitrate concentrations to achieve SND while
operating at low dissolved oxygen concentrations. If ammonia concentrations increase above the specific set point,
aeration is turned up to increase DO to enhance nitrification. If nitrate concentrations increase above the specific set
point, aeration is turned down or off to create more favorable anoxic conditions to support denitrification. Multiple
reactors are utilized in parallel, and the reactor effluent discharges to secondary clarifiers.
Overall, the SND activated sludge process is an innovative process that reduces energy use by operating at decreased
DO concentrations and eliminates costly recirculation pumps and carbon addition compared to conventional
sequenced nitrification and denitrification activated sludge process. Three different technologies were evaluated for
operation using the SND process: (i) extended aeration, (ii) conventional aeration, and (iii) high rate aeration. The
evaluation included treatability testing, biological process modeling, and a comparison of equivalent annual costs.

5. Treatability Testing
To establish and support proposed TN limits for the proposed Novozymes NPDES permit based on an analysis of the
Best Available Technology Economically Achievable, treatability testing was performed on three (3) treatment
technologies capable of achieving biological nitrogen removal. TP limits were established independently of
treatability testing, as described in Section 9.2. Although the existing treatment process provides partial nutrient
removal, enhanced nitrogen removal was not targeted, as Novozymes' effluent permit limitations did not require this
level of treatment, thus treatability testing was necessary to establish the TN limits attainable.
5.1 Treatability Testing Approach
Treatability testing was performed to establish the soluble refractory organic nitrogen and nitrate effluent
concentrations for each of the three technologies evaluated. The ultimate goal of treatability testing is to determine
the effluent refractory organic nitrogen and nitrate to support effluent limits for TN for the Novozymes NPDES
permit based on analysis of Best Available Technology Economically Achievable.
While ammonia and particulate organic nitrogen concentrations were tracked during the treatability study, it is
anticipated that these sub -components of total nitrogen will be based on water quality and limits of technology. It is
expected that the NPDES permit will contain a water quality based ammonia limit of 1.o mg/l. For particulate
organic nitrogen, it is assumed Novozymes will install tertiary filtration to remove particulate organic nitrogen. As
such, a technology based limit is proposed for this component of total nitrogen. Tertiary filtration is expected to
produce an effluent TSS of <3.0 mg/Lii. Assuming the TSS is biological in nature, e.g. biomass at 12% nitrogen, the
estimated particulate organic nitrogen expected from the filter effluent is 0.36 mg/l. For the purposes of the BAT
analysis, it is therefore assumed that the effluent ammonia limit will be 1.o mg/l and the effluent particulate nitrogen
concentration with tertiary filtration is estimated to be 0.36 mg/L.
The treatability testing protocol was developed to best simulate this full-scale treatment technology. Since automated
DO control is difficult to implement within bench scale testing, a sequencing approach was utilized to simulate the
reactors and demonstrate treatability. The bench scale reactors were operated as true batch reactors, without
continuous feed/draw, due to the challenges associated with balancing flow rates to maintain continuous flow
conditions on a small scale.
Initially, to mimic continuous flow in a batch reactor vessel, the testing involved several cycles of aeration/anoxic
conditions. Early testing results revealed ineffective denitrification with this approach, as nitrate concentrations were
high at end of batch. This is likely due to the lack of COD for substrate in the later anoxic cycles. In response, the
protocol was revised to operate with only one aerobic and anoxic cycle per batch. This change in protocol would
mimic the control logic of the Novozymes reactors and confirm that robust SND could be achieved with the
Novozymes Franklinton, NC wastewater.
Under the revised protocol, bench scale reactors were operated with a distinct aeration phase which was terminated
upon achieving an ammonia -nitrogen concentration less than 1.o mg/L to simulate the full-scale control logic when
aeration is activated. The bench scale reactors were then operated with an anoxic phase with supplemental carbon
addition until the nitrate reached a concentration less than 1.o mg/L to simulate the full-scale control logic when the
aeration is deactivated and the reactors are in mix phase. This sequence represented one reaction batch in the bench
scale reactors. Full-scale, this sequence would repeat continuously in small time increments in the continuous flow
through reactors.

The treatability testing protocol was approved by the Division in 2017. Treatability testing was performed in 2-liter
reactors mixed on a Phipps & Bird jar tester. Reactors were aerated with diffuser stones and miniature air pumps.
Each reactor was operated at different F:M loading rates to mimic the three evaluated technologies:
Reactor i = Extended Aeration at F:M of o.i (units of mg COD/mg MLVSS*day),
• Reactor 2 = Conventional Aeration at F:M of 0.5, and
• Reactor 3 = High Rate Aeration at F:M of 0.7.
Initially, from July 12-July 20, 2017, reactors were operated with multi -phased nitrification/denitrification by cycling
the aerators on/off in 3o-minute intervals. This protocol was intended to simulate continuous flow SND. After
running multiple batches under this configuration, effluent data indicated nitrate concentrations were higher than
expected and that sufficient carbon was not remaining during the later anoxic cycles to support complete
denitrification. These results were not entirely unexpected, as the reactors were not operated with continuous
influent feed and therefore the rate of denitrification was very low. This differs from the approach that will be
implemented full-scale, which includes continuous feed to provide carbon to support higher denitrification rates. In
addition, the aeration/anoxic phases on the bench scale were operated on a timed basis rather than utilizing real time
data (NH3 and NO3) to control DO as will be the operational approach full-scale.
For testing performed from July 21 — August 4, 2017, the protocol was modified for each batch to operate with a
single aerobic cycle followed by a single anoxic cycle. Supplemental carbon was added to the reactors at the beginning
of the anoxic cycle to support higher denitrification rates. The final protocol included the following sequence:
1) Feed
a) Feed Novozymes wastewater at volumes required to achieve the three food -to -mass loading conditions
2) Aeration Cycle
a) Aerate the reactor until the reactor ammonia concentration is < 1.o mg/L
3) Anoxic Cycle
a) Stop aeration and continue mixing the reactor
b) Dose supplemental carbon (acetic acid) to support denitrification at a Chemical Oxygen Demand (COD)
to Nitrate ratio of 6
c) Mix the reactor until the reactor nitrate is < 1.o mg/L
4) Settle
a) Stop mixing and allow biomass to settle
5) Decant
a) Decant reactor and collect effluent samples for analysis
Effluent samples were analyzed both by a certified laboratory and by Dewberry personnel. Dewberry analyzed
samples using Hach test kits to identify the end of aeration/anoxic cycles and to assess reactor performance in real
time. The results presented within this report used to establish effluent limits are based solely on certified laboratory
data. Due to large sample volumes required by the certified laboratory, effluent from approximately two to three
reactor batches were composited to create a certified laboratory sample.

The reactors were analyzed weekly for total suspended solids and volatile suspended solids. Reactors were also
monitored regularly for pH and dissolved oxygen. Reactor pH was adjusted as needed to maintain the pH at
approximately 7.5-9 standard units (s.u.). Reactor batch effluent samples were analyzed by the certified laboratory for
the following parameters:
• Soluble COD . NH3
• Soluble Carbonaceous 5-day BOD Soluble TKN

5.3 Performance Testing Results
Performance testing was performed over a 19-day period beginning July 21, 2017 and ending August 9, 2017. During
this time, six (6) wastewater influent samples were collected from Novozymes to utilize in feeding the reactors.
Using the collected Novozymes wastewater batch samples, seventeen (17) treatability testing batches were performed,
M1 through M17, using the protocol previously described. Effluent reactor results were analyzed by a certified
laboratory, and the results are presented in Appendix I. Reactor logs and process control laboratory analyses
performed by Dewberry are presented in Appendix J. Results in Appendix J were used to aid in reactor operations
(e.g. when to terminate cycles, adjust pH, etc.) and were not used to calculate BAT TN limit. Only certified laboratory
results were used to calculate the BAT TN limit.
A comparison of certified lab data to internal process control lab data identifies a positive correlation for the 17
treatability test batches performed, with the exception of Reactor 3: High Rate Aeration (0.7 F:M), which exhibited a
poor correlation for batches M6 — Mil. Table 5.2 below provides the calculated variability between average internal
process and certified lab data.
Dewberry Novozymes North America, Inc. I Best Available Technology Analysis 116

Measured Internal Process and Certified Lab Data
(,)Data presented in Table 3 is represents the absolute difference between the average value
of internal process measurements and average value of certified laboratory analysis.
(z)Omits data from Batch Run M6 - Mil.
Internal process data collected for Reactor 3 during the six treatability batch runs, batches M6-Mil, indicates average
NH3 and sTKN concentrations of 0.47 and io.8 mg/l respectively. Certified laboratory results indicate average NH3
and sTKN concentrations of 16.5 and 28.6 mg/l respectively. This is a variability of over 15 mg/l between internal and
certified laboratory data for both parameters. In comparison, the variability of batch tests Mi — M17 for the three (3)
reactor configurations, omitting data from Reactor 3 batches M6-Mil, results in an average NH3 and sTKN variability
of less than 0.32 and 3.73 mg/l, respectively. Due to the high variability between internal process and certified lab
data for Reactor 3 batch tests M6-Mil, the certified lab data for these batches are to be omitted in the final
calculations to determine the BAT limits for nitrogen. It should be noted that inclusion of the Reactor 3 batches M6-
Mii would result in a higher BAT limit for that technology. The decision to omit these results from the BAT limit
calculation was approved by the Division in September 2018 (Appendix Q.
Table 5.3 summarizes the 95th percentile and maximum reactor effluent certified lab data results. The 95th percentile
reactor effluent is presented, as that data is used to develop the effluent total nitrogen limit. This is consistent with the
EPA's methodology for establishing monthly average effluent limits. The 95th percentile is the basis for long-term
average in order to accommodate reasonably anticipated variability within the control of the facility (EPA NPDES
Permit Writers' Manual, 201o, EPA-833-K-io-ooi).

With the exception of nitrate, the effluent nitrogen species increased in concentration with increasing food -to -mass,
as expected. The 95th percentile effluent refractory soluble organic nitrogen ranged from 1.28 — 11.6 mg/l, increasing
with increasing food -to -mass, and comprised 4o%-96% of the total nitrogen. If data from batches M6-Mil was
included in the Reactor 3 analysis, the maximum effluent concentration for soluble organic nitrogen would increase
Dewberry Novozymes North America, Inc. I Best Available Technology Analysis 117

from 12.7 to 13.2 mg/l. Using the 95tn percentile data yields a more stringent, yet achievable, BAT TN limit..
Maximum concentrations were at most io% greater than 95th percentile results and as such further modeling and
BAT calculations for each alternative technology were performed only using the 95th percentile data. The effluent
refractory soluble organic nitrogen and nitrate were then used to develop an effluent total nitrogen limit for each
technology evaluated (see Section io below).

6. PROPOSED PROCESS TREATMENT DESCRIPTION
Following treatability testing, Dewberry performed preliminary design calculations for each technology to evaluate
WWTP upgrades necessary to achieve TN removal at Novozymes' projected direct discharge flow of 2.0 MGD. In
addition to processes largely responsible for TN removal, other unit processes were evaluated as necessary to comply
with expected limits for BOD5, TP, and TSS and to accommodate the higher future flow rates. For the purpose of this
BAT analysis, it is assumed that the existing anaerobic up -flow reactor will continue to be used for side stream pre-
treatment of COD of the permeate stream. Per the anaerobic system design specifications, it is assumed that use of
this system will provide COD reduction of 24,00o lb/day. Treated effluent from the anaerobic reactor will mix with
the remaining influent wastewater prior to the proposed SND treatment process. The raw influent wastewater
characteristics, as well as the influent to the proposed SND process, are presented in the table below.

A block flow diagram detailing Novozymes' proposed wastewater treatment upgrades is attached as Appendix K. The
following section provides sizing criteria for major equipment required to upgrade the existing facility to a SND
activated sludge process. This section also identifies which unit processes were included in the economic analysis to
identify proposed BAT TN limits. Major equipment to be installed is summarized in the attached preliminary
equipment specification table in Appendix L. Detailed discussion related to biological process modeling is provided
below in Section 7.
6.1 Primary Clarification
A new primary clarifier is required to supplement the existing primary clarifier due to the increased hydraulic and
solids loading to the treatment process. The primary clarifier shall reduce solids present in the influent wastewater.
The primary clarification unit process step shall also include capacity for phosphorus removal through chemical
precipitation, such as the addition of ferric chloride.
Using October 201.6- October 2018 flow data, the historical average flow to the primary clarifiers was 0.76 MGD,
resulting in an overflow rate of 790 gal/ft2/d for the existing clarifier. This historical overflow rate of 790 gal/ft2/d is
nearly within the recommended loading rate of 800-1,200 gal/d/ft2 for primary clarifiers (Metcalf & Eddy, pg. S98).
This loading rate has provided sufficient settling of solids for the Novozymes facility in the past, and the same
overflow rate was used to size the new primary clarifier.
Dewberry Novozymes North America, Inc. I Best Available Technology Analysis 119

The proposed upgrade for this unit process will be consistent between all three treatment technologies evaluated,
and therefore is not included in the BAT economic analysis to determine BAT TN limits
6.2 Bioreactors
Above ground, bolted stainless steel bioreactor tanks shall be provided for the proposed SND activated sludge system.
Bioreactor tanks were sized for each evaluated technology to provide the required process volume based on the
selected F:M ratio, mixed liquor volatile suspended solids (MLVSS) concentration and influent COD loading. For the
purpose of the BAT analysis, it is assumed that each technology shall operate a MLVSS concentration of 4,000 mg/l
with an influent COD concentration identified in Table 6.1. Setting the MLVSS and COD concentrations constant
allows the bioreactor volumes to be calculated from the selected F:M ratio.
Therefore the bioreactor volume for each technology evaluated will differ as identified in the attached preliminary
equipment specification table (Appendix L). The required bioreactor configuration for the conventional aeration
treatment technology, e.g. F:M = 0.5, was provided to vendors for pricing. Bioreactor costs for the extended aeration
and high rate aeration technologies were scaled accordingly from received vendor quotes. Such costs shall be
included in the BAT economic analysis to determine BAT TN limits.
6.3 Aeration Equipment
Bioreactor tanks will be equipped with fine bubble diffuser aeration grids and surface mixers. Air supply will be
provided by positive displacement or centrifugal blowers for the required design air flow and pressure as identified in
the attached preliminary equipment specification table (Appendix Q. Each bioreactor tank shall have dedicated
aeration grids and blowers. Mixing shall be provided by fixed or floating direct drive mixers. As the different
technologies operate at varying F:M ratios, the required oxygen supply will also vary due to variable solids retention
time (SRT) and biosolids generation rates.
The required aeration equipment for each technology will differ as identified in the attached preliminary
specification table (Appendix L). The required design air flow rate and pressure, tank size and TSS concentrations for
the conventional aeration treatment technology, e.g. F:M = 0.5, was provided to vendors for pricing on diffused
aeration grids, centrifugal blowers, and tank mixers. Additional pricing was also identified for the positive
displacement aeration blowers for the extended aeration process, e.g. F:M = o.i. Blower and tank costs for the
extended and high rate aeration technologies were scaled accordingly from received vendor quotes. Such costs shall
be included in the BAT economic analysis to determine BAT TN limits.
6.4 Secondary Clarification
A new concrete secondary clarifier is required to supplement the existing secondary clarifier to treat the higher future
flow rate conditions. The return activated sludge (RAS) and waste activated sludge (WAS) pump station will also
require modifications and upgrades. The new RAS pumps will provide 150% of influent flow return, while the WAS
pumps will be sized to maintain the desired MLVSS concentration. Both pumps will be self -priming pumps.
The proposed secondary clarifier is sized based on the historical solids loading rate. Historically, the existing
secondary clarifier operated at a solids loading rate of 0.51 pounds per day per square foot (gal/hr/ft2). The historical
solids loading rate was calculated based on an existing clarifier diameter of 87 ft and an average historical clarifier
influent flow rate of 0.73 MGD. The historical solids loading rate is below the recommended loading rate of 1.0-1.5
Dewberry Novozymes North America, Inc. I Best Available Technology Analysis 120

lb/hr/ft2 for secondary clarifiers (Metcalf & Eddy, pg. 687). Using the projected flow of 2.0 MGD, the secondary
clarifier was sized to maintain the historical solids loading rate for all three technologies.
The proposed upgrade for this unit process will be consistent between all three treatment technologies evaluated,
and therefore is not included in the BAT economic analysis to determine BAT TN limits.
6.5 Dissolved Air Flotation (DAF)
Chemical precipitation is currently employed onsite for phosphorus removal and additional treatment capacity is
required for the flow increase. Novozymes currently utilizes a ioo ft2 DAF with ferric chloride and lime addition for
phosphorus removal. Historically, the DAF has been operated at an average surface loading rate of 2.9 gpm/ft2. This
surface loading rate is calculated based on the 2014-2015 average effluent flow rate to Franklin County of 0.423 MGD.
The historical surface loading rate is within the recommended range of 0.2 — 4.0 gpm/ft2 for dissolved air flotation
(Metcalf & Eddy, pg. 423).
Two additional DAFs at 250 ft2 each are proposed to supplement the existing DAF. The surface loading rate for the
new DAFs and the existing DAF at 2.0 MGD will be 2.3 gpm/ft2, which is below the historical surface loading rate and
within the recommended range. In addition, Novozymes will have the ability to vary the ferric addition rate as needed
to achieve phosphorus removal.
Since the sizing criteria for the DAFs is flow -based, the proposed upgrades to the DAF system and the upgrade costs
will be the same for each treatment technology. Also DAF costs are for TP removal and not TN removal, thus such
costs shall not be included in the BAT economic analysis to determine BAT TN limits.
6.6 Reverse Osmosis (RO) System
The reverse osmosis system is included to reduce the concentration of total dissolved solids (TDS), principally
potassium, in the Novozymes' discharge. It is also anticipated that the RO system will provide, on average,1.o mg/1
total nitrogen removal.
RO reject will be sent to an evaporator, with bottoms disposed of at an approved facility. Novozymes is currently
seeking environmentally advantageous disposal options for evaporator bottoms, but has yet to finalize reuse options
at this time.
Since the sizing criteria for the RO system is based on TDS removal, principally potassium removal, costs
associated the RO system and associated evaporators are not included in the BAT economic analysis to determine
BAT TN limits.

7. BIOLOGICAL PROCESS MODELING
Dewberry performed biological process modeling using Biowin® for each proposed technology. The purpose of
biological process modeling was to evaluate the ammonia, nitrate/nitrite and organic nitrogen concentrations present
in the effluent wastewater stream; effluent TP concentrations were not evaluated through process modeling. The
influent conditions used in each model are presented in Table 5.2, with the 95th percentile soluble refractory organic
nitrogen influent concentrations determined from treatability testing as presented in Table 5.4. A biological process
model was constructed for each technology assuming a SND process. Appendix M is a summary of input and output
parameters from Biowin.
Each model consists of a bioreactor with a DO concentration ranging from 0.3 to 0.5 mg/L. Using a mixed liquor
suspended solids (MLSS) concentration of 4,000-4,500 mg/l, the bioreactor for each technology was sized to achieve
the appropriate F:M ratios. The existing above ground and in -ground 0.24 MG tanks (Toi and Toe) were
incorporated into the model for polishing SND treatment of ammonia and nitrate downstream of the bioreactors. The
biological system was modeled as completely mixed, aerated reactors modeled in series, using a DO concentration
ranging from 0.2 to 0.5 mg/L. The total required surface area of the two secondary clarifiers are included as one
clarifier in the model. Figure 3 provides a schematic of the model unit processes.

The results of the process modeling indicate that ammonia and nitrate/nitrite concentrations are reduced to less than
1.o mg/L for each technology. Table 7.2 below lists the predicted effluent concentrations of ammonia, nitrate/nitrite,
and recalcitrant organic nitrogen for each technology evaluated. Therefore, it is anticipated that the proposed
treatment technologies evaluated can meet the speculative water quality limit for ammonia of 1.o mg/l.

The results of process modeling represent effluent from secondary treatment and are not representative of final
tertiary treated wastewater. Process modeling predicts a secondary effluent TSS concentration of approximately 17
mg/l for each technology evaluated. Tertiary filtration is expected to produce an effluent TSS of <3.0 mg/L.
Assuming the TSS is biological in nature, e.g. biomass at 12% nitrogen, it is estimated that the tertiary filter will
reduce the secondary effluent TN concentration by 1.7 mg/l for each technology, calculated as follows: (17.0 mg/1-
3.0 mg/1)*.12% =1.7 mg/l. Table 7.3 provides the estimated tertiary effluent TN concentrations as well as the
modeled secondary treated effluent TN concentrations. These values correspond well with the proposed BAT TN
concentrations determined from treatability testing as presented in Section 9.o.

8. EQUIVALENT ANNUAL COST ANALYSIS
Utilizing the results of the preliminary design and process modeling, capital and operating opinions of probable cost
were developed for each technology evaluated to establish the equivalent annual costs for TN removal. Costs for TP
removal were not evaluated. Opinions of probable cost were developed for the following technologies:
• Alternative 1- Extended Aeration
• Alternative 2 — Conventional Aeration
• Alternative 3 — High Rate Aeration
Capital costs were included for treatment equipment and appurtenances which are related to TN removal, and
included estimates for installation costs, with allocations for contractor overhead, profit, and general conditions,
engineering, and construction labor and construction management. Annual recurring operational costs were
estimated for chemicals, residuals disposal, utilities, sewer use fees, maintenance and nutrient offset fees.
Capital costs were estimated for Alternative 2 based on vendor quotes and installation factors. For Alternatives i and
3, the capital and annual recurring costs for Alternative 2 were scaled when appropriate. For example, the capital
costs for the bioreactors were scaled as the required reactor volume will increase with a decreasing food -to -mass. A
discussion of which costs were included was presented previously in Section 6.o for each proposed unit process. For
this reason, some of the items presented in the cost estimates included in the concurrently submitted EAA report are
not included in the BAT cost estimates. The BAT cost estimates only focus on capital equipment costs necessary for
biological TN removal, thus making the BAT cost estimates a subset of the EAA cost estimates.
Capital and recurring opinions of probable cost for each alternative are presented in Appendix N. The opinions of
probable cost were converted to an equivalent annual cost based on a 5-year period and an annual discount rate of
7%, which are the standard assumptions used by Novozymes to evaluate project financials. Table 8.1 summarizes the
capital, operating, and equivalent annual costs for each alternative.

9. BAT LIMIT DETERMINATION
9.1 Total Nitrogen BAT Limits
Novozymes commissioned the treatability testing to support development of BAT TN limits for the proposed NPDES
discharge. To determine BAT TN limits for the discharge, the treatability testing results and cost estimates were used
to compare the economic factors for the alternatives evaluated. This process is summarized below:
i. Identify achievable effluent total nitrogen limits for each technology evaluated.
2. Develop Equivalent Annual Costs for each technology evaluated.
3. Calculate normalized nitrogen removal costs for each design technology evaluated based on the equivalent
annual cost and total annual mass of nitrogen removed.
4. Compare the normalized nitrogen removal costs for each technology evaluated to each other.
The effluent total nitrogen limits presented in Table 9.1 were developed based on the sum of the following sub-
components: soluble organic nitrogen, nitrate/nitrite, ammonia, and particulate total nitrogen. The effluent soluble
organic nitrogen and nitrate components presented are based on the 95th percentile treatability testing results for
each technology evaluated. The 95th percentile reactor effluent concentrations were used to develop the effluent total
nitrogen limit to be consistent with the EPA's methodology for establishing monthly average effluent limits. The
ammonia effluent limit is assumed to be water quality based at i.o mg/l. The particulate total nitrogen is estimated to
be 0.36 mg/l for tertiary filter effluent based on assuming a biological TSS filter effluent of 3.0 mg/l.
Table 9.1 presents the calculated effluent total nitrogen BAT limits proposed for each technology evaluated.
Calculated effluent total nitrogen BAT limits are also presented graphically in Figure 4.

Figure 4. TN Effluent Results Comparison
For reference, the use of maximum treatability testing results in lieu of 95th percentile results would increase the
proposed effluent BAT TN limits to 3.9, io.6 and 13.9 mg/l for Alternatives 1, 2, and 3 respectively. This accounts for
the 1.o mg/l RO credit. Using the 95th percentile results in lieu of the maximum results represents percent decreases
Of 3%,17%, and 9%, respectively of three technologies evaluated.
For each technology evaluated, the annual mass of nitrogen removed was calculated based on the design flow rate, the
influent TN, and the effluent BAT total nitrogen limits provided in Table 9.1. A normalized nitrogen removal cost was
then calculated based on the mass of nitrogen removed and the annual equivalent cost.

normalized nitrogen removal costs for each alternative. The graphical relationship depicts a much steeper slope
between Alternatives i and 2 compared to Alternatives 2 and 3. This indicates that there is significant additional
incremental cost to achieve the limits proposed for Alternative 1 compared to Alternative 2 and 3.

A review of the costs and associated information indicates that Alternative 2 is the best available alternative that is
economically achievable. The basis for this analysis is summarized below:
The Alternative 2 normalized nitrogen costs are 52% less and 3% more compared to Alternatives 1 and 3,
respectively. The graphical relationship between the costs indicate significant incremental cost increase
between Alternatives 2 and 1. Relationship between Alternatives 2 and 3 reveals a much lower incremental
cost increase.
Novozymes North America, Inc. I Best Available Technology Analysis 128

The additional annual costs to remove 23,774 lbs of nitrogen, the difference between Alternatives 2 and 3, is
approximately $16.9 per additional lb TN removed. This is deemed to be economically feasible and
reasonable.
The additional annual costs to remove 30,441 lbs of nitrogen, the difference between Alternatives 1 and 2, is
approximately $309 per additional lb TN removed. This is deemed to be economically infeasible and
unreasonable.
Estimated utility costs for Alternative 2 is 78% less than Alternative 3. Utility costs for Alternatives 2 and 3
are similar.
The total annual reoccurring costs for Alternative 2 is 34% less and 3.0% less compared to Alternatives 1 and
3, respectively.
Factors considered in assessing BAT include the cost of achieving BAT effluent concentrations, the age of equipment
and facilities involved, the processes employed, engineering aspects of the control technology, potential process
changes, non -water quality environmental impacts (including energy requirements), and economic achievability.
Based on the equivalent annual costs and normalized nitrogen removal costs, Alternative 2, Conventional Aeration,
F:M = 0.5, proves to be the best performing alternative evaluated that is economically reasonable, and thus is deemed
the basis for the Best Available Technology Economically Achievable (BAT) limit for TN. Therefore, the proposed
monthly average total nitrogen limit is provided in Table 9.4. This value assumes a 1.o mg/l reduction from the
reverse osmosis system.

For reference, municipal TN surcharge rates within the State of North Carolina were compiled and are presented in
Table 9.5. Nitrogen removal unit costs for industrial wastewater treatment plants are not publicly available, so
municipal TN surcharge rates were used for this comparison. Municipal nitrogen surcharge rates represent the costs
municipalities impose on industrial dischargers to treat nitrogen in excess of typical municipal concentrations within
their POTWs and provide an indication of reasonable and economically achievable treatment costs. The average total
nitrogen surcharge rate based on 5 municipalities in North Carolina is $1.96/lb of nitrogen. The maximum surcharge
rate based on the 5 municipalities is $5.00/lb of nitrogen. The normalized nitrogen removal costs for the three
technologies evaluated for the Novozymes facility exceed the average and maximum municipal surcharge rates.
While the normalized nitrogen removal costs for Alternatives 2 and 3 are 22-26% higher than the maximum
municipal surcharge rate, Alternative 1 costs are more than 2.5 times the maximum municipal surcharge cost. This
analysis provides additional support for the selection of Alternative 2 as the basis for BAT total nitrogen limit.

9.2 Total Phosphorus BAT Limits
Review of recent TP data (Appendix G) indicates a sixteen month period where the monthly effluent TP averaged less
than i.o mg/l. This demonstrates that phosphorous removal to less than i.o mg/1 is technically feasible with chemical
precipitation. The data is not consistently below the proposed limit because Novozymes is not currently required to
meet a monthly average TP limit of 1.o mg/L and therefore does not dose chemical at the rate required to consistently
maintain that level of treatment. Theoretically, for chemical precipitation of phosphorous, the effluent ortho-
phosphate concentration is directly related to the chemical dose (Metcalf & Eddy, pg. 5o6). Figure 5 below presents
the effluent TP concentrations as a function of the metal coagulant dose'°. It should be noted that the data in Figure 5
is presented on a logarithmic scale; therefore to achieve additional effluent TP of o.i.o mg/L requires approximately
2-10 times the chemical dose to achieve TP of i.o mg/l.
In the future, Novozymes will increase the chemical dose to consistently achieve effluent TP < i.o mg/L. A BAT of i.o
mg/L is deemed appropriate as significantly higher chemical dose ratios are required to produce nominal decreases in
effluent TP in the range below i.o mg/L, as demonstrated in Figure 5. In addition, the proposed WWTP upgrades will
include chemical addition in the primary clarifiers to support chemical phosphorus precipitation and tertiary
filtration to provide particulate TP removal. Therefore, Novozymes proposes an effluent BAT limit of i.o mg/L TP.

10.CONCLUSIONS
The proposed discharge location on Cedar Creek is located in the Tar -Pamlico River Basin. As a result and as
discussed in correspondence from the Division dated December 14, 2016 (Appendix D), the Division requested that
Novozymes prepare and submit a Best Available Technology Economically Achievable (BAT) analysis to assist in
establishing limits for TP and TN. Three (3) treatment technologies were evaluated to identify the BAT Economically
Achievable limits for TN, which in general represent the best existing performance of treatment technologies that are
economically achievable within an industrial point source category (EPA NPDES Permit Writers' Manual, 20io, EPA-
833-K-io-ooi). The treatment technologies evaluated were:
• Alternative is Extended Aeration at F:M of o.l (units of mg COD/mg MLVSS*day)
• Alternative 2: Conventional Aeration at F:M of 0.5
• Alternative 3: High Rate Aeration at F:M of 0.7
Treatability testing was performed to determine the effluent soluble refractory organic nitrogen and nitrate for each
technology evaluated. The technically achievable effluent total nitrogen concentrations were calculated from the sum
of the 95th percentile effluent soluble refractory organic nitrogen for each reactor, the 95th percentile effluent nitrate
from each reactor, the ammonia monthly average limit of 1.o mg/L, and the estimated particulate total nitrogen of
0.36 mg/l. The technically achievable effluent total nitrogen concentration for the three design conditions were
determined to be 3.8 mg/l, 8.8 mg/l and 12.7 mg/l; this includes a nitrogen removal credit of 1.o mg/l from the RO
treatment process. Biological process modeling was also performed that identified that each alternative would
produce secondary effluent with NH3 and NO3 concentrations of less than i.o mg/L, each.
The EPA definition of a BAT limit requires it be both technically and economically achievable. Capital and annual
recurring costs were estimated for each of the three technologies evaluated and were used to determine annual
equivalent costs. For the BAT TN limit, the annual equivalent costs were normalized per pound of nitrogen removed
for each alternative evaluated and are summarized in Table io.i.

Based on the equivalent annual costs and normalized nitrogen removal costs, Alternative 2, Conventional Aeration,
F:M = 0.5, proves to be the highest performing alternative evaluated that is economically achievable, and is deemed
the Best Available Technology Economically Achievable limit. Normalized nitrogen costs for Alternative 2 are 52
less and 3% more compared to Alternatives i and 3, respectively. The graphical relationship (Figure 4) between
Normalized nitrogen costs indicate significant incremental cost increase between Alternatives 2 and 1. The graphical
relationship between Alternatives 2 and 3 reveals a much lower incremental cost increase. The Equivalent Annual
Costs for Alternative 2 is 53% less and 5% more compared to Alternatives 1 and 3 respectively. The additional annual
costs to remove 23,774 lbs of nitrogen, the difference between Alternatives 2 and 3, is approximately $16.9 per lb TN
removed. This is deemed to be economically feasible and reasonable. The additional annual costs to remove 30,441

lbs of nitrogen, the difference between Alternatives 1 and 2, is approximately $309 per lb TN removed. This is
deemed to be economically infeasible and unreasonable.
For TP, a BAT of i.o mg/L is deemed appropriate as significantly higher chemical dose ratios are required to produce
nominal decreases in effluent TP in the range below 1.o mg/L. In addition, the proposed WWTP upgrades will include
chemical addition in the primary clarifiers to support chemical phosphorus precipitation and tertiary filtration to
provide particulate TP removal. Therefore, Novozymes proposes an effluent BAT limit of i.o mg/L TP.

Franklinton, NC

Dear Dr. Stadelman:
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
S. JAY ZIMMERMAN
Director
On July 16, 2015, the Raleigh Regional Office, Water Quality Regional Operations Section
received your proposed Corrective Action Plan (CAP) for the above -referenced site. Review and
conditional approval for this CAP was delayed in anticipation of legislation (HB 765), which contains
provisions to allow for monitored natural attenuation of groundwater at certain permitted facilities.
As described in Title 15A North Carolina Administrative Code, Subchapter 2L, Classifications and
Water Quality Standards Applicable to the Groundwaters of North Carolina (15A NCAC 2L), the
Division's final approval of a CAP is contingent upon consideration of public input received following
notification in accordance with 15A NCAC 2L .0114. Certified mail receipts were provided, showing proof
of notification to the property owners and occupants potentially affected by the approval of the proposed
CAP submitted pursuant to 15A NCAC 2L .0106(1), "using natural attenuation processes."
Based upon a review of the information submitted in the CAP and after considering any public
comments and the Raleigh Regional Office recommendations, I am hereby granting conditional approval
to implement the CAP. The Division's decision is based on the information submitted in the proposed CAP
and supporting documents, and is contingent upon the following conditions:
1. The NZNA-recommended approach is for selected area active remediation via
groundwater extraction associated with Farms 1 and 2 and monitored natural attenuation
State of North Carolina I Environmental Quality I Water Resources

(MNA) of the impacted groundwater found in association with Farms 3 and the Smith,
Pickrel, and Alston properties and adjoining NZNA properties. The details of the CAP
Phase I and Phase 1I are found in Sections 6.3-7.2 of the CAP on pages 36-44.
a. Focused ground water extraction includes the continued extraction of groundwater
via six (6) existing groundwater recovery wells located north of Farm 1, six (6)
proposed recovery wells on the east side of Farm 2, and eight (8) proposed
groundwater recovery wells on the north side of Farm 2. Further details on this are
available in the CAP Section 7.1.1.2 on page 40.
b. As discussed in Section 6.1.1, natural attenuation of impacted groundwater at
points beyond the compliance boundary will require a reduction in irrigation rates
primarily to reduce total dissolved solids (TDS) loading. Reduced irrigation rates
require an off -setting increase in direct discharge of treated wastewater.
2. The Monitoring Plan is discussed in Section 8.0, beginning on page 45 of the CAP. Tables
21 and 22 summarize the monitoring wells to be included in the groundwater monitoring
program by farm.
a. On Fart 1, Farm 2, and the Smith/Pickrel/Alston/NZNA Properties, all of the trend
monitoring wells and the background monitoring wells will be sampled for Nitrate -
Nitrogen and TDS annually. All of the new and existing compliance monitoring wells
will be sampled for Nitrate -Nitrogen and TDS semi-annually in the fast year, and
annually after the first year.
b. On the Joumigan and Goswick Farms where MNA is proposed as the remedial
strategy, NZNA proposes to monitor groundwater for 5 years, examine data collected,
and report the findings to DWR. The existing and new trend and background
monitoring wells on these properties will be sampled for Nitrate -Nitrogen and TDS
three times per year.
c. New monitoring wells will be installed on the following properties, as mapped in
Figures 2, 3, 4A, 4B, and 5:
i. Farm 1: 9 new monitoring wells
ii. Farm 2: 6 new monitoring wells
iii. Farm 3: 4 new monitoring wells
iv. Smith, Pickrel, Alston, and NZNA Properties: 2 new monitoring wells
v. Journigan Property: 3 new monitoring wells
vi. Goswick Property: 1 new monitoring well
d. Known or potential water supply wells in the NZNA vicinity are included in Table 12,
and Figures 7 and 8. NZNA proposes to conduct monitoring upgradient of the Bowers,
Burt, McNeil, and Goswick water supply wells as outlined in the CAP Section 8.1.
DWR may recommend including the sampling of these water supply wells if any of
the upgradient monitoring wells show increases in nitrates or TDS over two or more
sampling events.
The surface water assessment plan is outlined in Section 6.2 of the CAP. A surface water
monitoring plan will be prepared and issued upon completion of pilot testing and the
selection of the final remedial options. This CAP Phase 3 includes the development of full-
scale design, costs, and permitting of the corrective actions. Approval of this CAP is
conditional upon receipt of an NPDES permit to allow for the treatment and disposal of
contaminated groundwater, which is required to comply with conditions of 15A NCAC
02L .0106(e), and .0106(l)(1).
State of North Carolina I Environmental Quality I `Hater Resources
512 N. Salisbury Street 11611 Mail Service Center I Raleigh, NC 27699-1611

4. Approval of this CAP is conditional upon successful demonstration that NZNA can
demonstrate compliance with 15A NCAC .0106(l)(6) upon completion of the surface water
assessment plan outlined in Section 6.2 of the CAP.
Upon receipt of additional information by our office, you may be required to perform additional
monitoring, conduct additional site assessment activities, assess the performance of the ongoing corrective
action, and/or evaluate the technological and economic feasibility of implementing a new technology at the
subject site. If NZNA cannot meet any of the conditions described in Conditions 1 — 4 above, a new
Corrective Action Plan may be required to meet the requirements of 15A NCAC 02L .0106.
You are required by 15A NCAC 2L .0114(c) to notify all interested parties, as specified in
paragraph (b) of that rule, that approval of the CAP was granted by the Director. Notification is required
by certified mail and must be made within 30 days of receipt of the Director's decision.
The above referenced restrictions have been determined to be applicable to the site and NZNA is
hereby approved in conjunction with the CAP. A survey plat delineating the areas of contamination at the
site and containing the information required in § 143B - 279.10.
A report detailing the findings of the monitoring effort must be submitted to this office on or before
the last day of March, July, and November of each calendar year. Failure to adhere to the requirements of
the CAP and this approval letter may be considered to be a violation of the rules, subject to possible
enforcement action by the Division.
If you have any questions, please call Laura Robertson of the Raleigh Regional Office at 919-791-
4200.

Dear Ms. Walsh:
The Division received your additional information in response to our letter from August 9, 2016. The
additional information document referenced the Tar Pamlico Phase III Agreement as the basis for
justifying the proposed total nitrogen (TN) limit of 6 mg/l and total phosphorus (TP) limit of 1 mg/l. Page
15 of the agreement stated that new discharges of any kind receive 1 mg/1 TP effluent concentration limits
if they exceed 0.05 MGD permitted flow and additionally 6 mg/1 TN effluent concentration if they exceed
0.5 MGD permitted effluent flow. However, the Phase III agreement referenced in your letter is no longer
in effect and the Phase IV agreement approved in July 2015 no longer includes the referenced statement.
In addition, 15A NCAC 02B. 0229 states that TN and TP limits for new industrial discharges that have
permitted flows greater than 0.05 MGD which are not members of the Tar Pamlico Basin Association are
to be established based on BAT. TN and TP limits of 6 mg/l and 1 mg/l apply to domestic POTWs. The
application does not demonstrate or support that 6 mg/1 TN and 1 mg/1 TP are BAT for the proposed
Novozymes industrial discharge.
The permit application must be revised to include a complete BAT analysis. The development of limits
based on BAT is a case -by -case determination which is dependent upon the characteristics and treatability
of the specific industrial wastewater. The BAT analysis should include evaluation and discussion of the
industrial process involved, wastewater characteristics and treatability, wastewater treatment technologies
evaluated, proposed treatment and expected reductions, and a comparison of the cost of treatment
alternatives considered. Treatability tests must be conducted unless sufficient data from treatment of
similar wastes are available. For industrial wastewaters it is important to consider the complexity and the
nature of nitrogen compounds (i.e. refractory or non -refractory nitrogen components) and clearly
demonstrate that the industrial wastewater is amenable to treatment under the selected treatment
technology.

1. Results above are in mg/L
2. The M in the batch number denotes the batch was operated with the modified protocol initiated on July 21, 2017.
3. Certified lab samples are composite samples of multiple cycles in order to provide laboratory with adequate volume
4. Effluent results for Reactor 3 batches M6 through M11 will be excluded from the BAT limit analysis. These results are not consistent with the analysis performed by
and are not consistent with the performance of other Reactor 3 batches.
5. Reactors were not operated in a manner to optimize for chemical oxygen demand or biochemical oxygen demand removal.

This message originated from outside your organization
Mike
Read below from my PD Blower guy. The new flow rate (well actually, the flow rate you originally asked for) really take
the blower type away from PD. I cannot imagine the quantity of PD's being practical for this application when compared
to multistage centrifugal or turbo blowers. We shall see.
In order to do 1275 SCFM @ 11 psig with a PD or screw blower you would need 3 blowers per tank to meet the
load. That would mean they would need 10 blowers (9 to meet the load and a spare). It would still be the exact same
blowers I gave you info on but they would need 10 total blowers not 4. This may be an application for Centrifugal or
Turbo blowers. They can use those for the base load and still look at using a screw or PD for turndown. Let me know
what they say.

I have reviewed your revised application and am pleased to offer the following budget proposal. For
this lower flow, I would go with this selection as it is more efficient at the new design condition. The
blower model remains the same but with a different impeller mix and smaller motor. Have included a
standard accessory and blower protection package.
Job Conditions: 10,000 SUM Air Flow per Blower
11.0 PSIG Discharge Pressure
360' Elevation
105OF Inlet Temperature
80% RH
Equipment List: 4 — Model 600.04 Multistage Centrifugal Blower
4 — Base Assembly with Baseplate, Coupling, Coupling Guard & Base Pads
4 — 650 HP 3/60/460-volt 3,550-rpm TEFC Motor
4 — 24" Inlet Filter Silencer, Panel Style
4 — 24" Inlet Butterfly Valve, Wafer, Manually Operated
4 — 24" Inlet Expansion Joint
4 — 20" Discharge Check Valve, Wafer
4 — 20" Discharge Expansion Joint
4 — Surge/Overload/Vibration Protection Panel, NEMA 12
Budget price for the above equipment is $642,000.00 FOB Syracuse, NY. Freight to the
jobsite, start-up service and training are not included in this price.
Due to the size of the project, payment terms will need to be discussed prior to order placement.
Drawings can be supplied in 3 to 4 weeks from receipt of an order. Estimated shipping time is 22 to
26 weeks from release for fabrication.
Please let me know if you have any questions or require any additional information.

Aqua Aerobic Systems recommends the use of a concrete pad on the basin bottom directly below the
mixer. If concrete is known to be nonresistant to the waste, other materials should be investigated. If basin
contains toxic wastes, user is advised to obtain engineering advice as to basin design and construction
necessary to prevent possible erosion and leakage. Aqua Aerobic Systems assumes no liability or
responsibility for any damage to basin bottoms or walls, or for any injuries or damages resulting therefrom.

To: Poulios, Michael; Lawrence, Jordan
Subject: Franklinton, NC - Dewberry Biopharma project - SSI Aeration Biological treatment basin
(Q-102518 [A])
Attachments: Dewberry Biopharma project- (Heyward Incorporated )_Q-102518 [A].docx
This message originated from outside your organization
Michael and Jordan:
Attached is the revised layout and relevant information on Fine bubble Aeration System for
Dewberry Biopharma project based on the lower air flow rate given yesterday (10,000 scfm per
basin). This is for the biological basin as we have sent earlier the coarse bubble diffused air
recommendation for the EQ, digester and reaeration tanks.
The costing and layout is based on each of the three (3) tanks being 107' diameter X 20' tall.
TOTAL LUMP SUM Budgetary Price: FOB jobsite including site service is $ 895,000.00.
The service is 3T/6D. Don't know if that is enough for installation and training and commissioning. Just
depends on the schedule and your requirements.
SSI Aeration kept the same number of diffusers in this revised proposal even with the reduced total air
requirement. In the prior or original proposal SSI Aeration used maximum air capacity of diffusers r,
now its came down to comfortable range for the diffuser.
If you have any questions and / or need clarification we would be glad to assist further.

Unique System Strengths
Complete product line -creating the system that fits your needs
SSI manufactures disc diffusers and coarse bubbled iffusers, and we mount these
products on a wide range of piping materials including PVC, CPVC, PP and Stainless Steel. We have
the ability to attach diffusers to pipe using saddles, grommets, or pre -assembled PODS. We can
provide retrievable systems or fixed grids, and systems in kit form or mostly factory assembled. We
try to understand and anticipate your needs, and fit our recommendations to your situation.
Piping system integrity- thicker wall pipe and double anchors for fewer breakages
Our piping is 38%thicker and has double rod support stands as standard -two anchors for each
support location means twice the resistance to hydraulic and thermal loads. Most often supports
fail due totem perature and water velocity. SSI locates two anchors where support is needed
most, helpingto increase product longevity.
Comprehensive design service and after sales support
SSI provides full design services, including biological and mixing calculations, process simu-
lations and hydraulic studies. We maintain a full drafting departmentwith 3D and animation
capabilities and we can assist with specifications and CAD drawings. Ourservice and installation
crew can hold your hand during the early stages of the project and ourworldwide multilingual
staff is dedicated to your complete satisfaction.
nteNgent Upgrade Options
Patented PTFE membranes prolong efficiency and reduce whole -life costs
SSI's patented PTFE membrane barrier properties not only reduce plasticizer extraction, shrinking,
and membrane hardening but also limit dynamic changes that can result from swell, such as
creep. Compared with uncoated products that are more susceptible to increases in DWP due to
more aggressive fouling and changes in physical properties and weight, the PTFE coated mem-
brane improves consistency of DWP (Headloss) values overthe product life. This directly impacts
long-term powercosts and the ability of the system to distribute air uniformly across the tank floor.
SSI Telemetry -the inside story solves maintenance problems
At the click of a mouse, you will know the DWP of yourd iffuser membranes, airflow rate to those
monitored diffusers, and airtemperature in the submerged piping system. You cansensevibra-
tion, pipe roll over, and water in the grid.Automatic moisture purging and automatic acid dosing
systems are available. Through multiple cameras, you can see both inside the grids, and surface
bubble patterns. Wet probes are also available for DO and WW temperature. Tracking all this data

Quick Connect
NPT Saddles
mount on nominal
US 4" or metric
114.3mm OD pipe.
They allow retrofit of 12"
to 9" discs without changing the
piping system. Quick Connect NPT Saddles
are made of polypropylene, and install into a
5/8" (16mm) hole.
GROMMETS
Grommets are
available for round AV
plastic or square
stainless steel pipes in
US or Metric dimensions. Installation is
simple. Multiple sizes are available based on
pipe wall thickness. Grommets install into
a 1-1/4" (32mm) chamfered hole.
CHECK VALVES
SSI fine and coarse bubble
diffusers are available
with optional check valves.
These are not required for
proper operation since most
diffusers are self -checking,
but they may give peace of mind to
the designer or operator.

Slotted band joints with stainless steel shear PVCwo shell
rings are suitable for disc -type fine bubble and cap -type coarse bubble
lateral plastic piping systems, in conjunction with SSI's fixed and guide
support stand system to manage thermal expansion and contraction.
Positive locking bolted stain-
less steel couplings are
suitable for drop

MOISTURE
SYSTEM
An airlift type purge system is used
in all SSl fine bubble aeration
systems to remove condensate
from the piping system. Purging
entrained water helps tip
ensure even air distribution I
to all diffusers in a grid. f
A ball valve is supplied with the
system and is opened manually.
Continuous urge s stems are available for retrievable -
type aeration systems, or w ere it is not possible to fasten
a purge line to a tank wall.
SUPPORTNU
STANDS
Support Stands N—I
are available in 3045S,
316SS or in ABS
plastic. SSI's standard is
304SS with drop -in
anchor bolts. In our
aeration piping systems,
support stands fulfill the dual role
of anchoring pipes to the floor and
controlling thermal expansion and
contraction. Special support stands
for uneven tank floors, for installing
into concrete ballast forms, and for
tanks with significant channel
velocity (with lateral supports) are
also available. ABS support stands
are Primarily
used with disc
diffusers and
plastic pipe,
where a low
capital cost is the
primary objective. ABSp1a5k-PP0rt1Wnd

SMART IDEAS FOR WATER
ACID DOSING
SYSTEM
In -situ Acid Dosing Systems are
available to control calcareous deposits
in the perforations which will reduce
membrane backpiessure.
PRESSURE
MONITORING
SYSTEM
Throughout the life of an
aeration system, oxygen transfe
efficiency may decline
somewhat when diffusers
become fouled, but headloss
can increase dramatically whicl
in turn increases energy costs.
A pressure monitoring system
the operator to better determine the optimal cleaning
frequency of the membranes- The fouling rate can vary
by aeration zone, hence it is recommended to install at
least one system in each zone.
TELEAMETRY S i STEAM
Adding a Telemetry System to
your aeration system will allow
you to remotely monitor factors
inside your tank from any PC,
tablet or mobile device.
Telemetry can be installed in new
systems or retrofitted through an
end cap into existing systems.
Telemetry sensors are available to
monitor variables in your system
such as temperature, vibration,
humidity, water detection, DO,
and other environmental factors.
