The permit lists the outfall to the Neuse River Estuary as Outfall 001. This outfall was renamed Outfall 002
to be compatible among NCDWR and USEPA dastabases and the eDMR electronic reporting system,
effective May 1, 2016. The Permittee was informed of this renaming via e-mail in April 2016.

According to the Final 2018 Integrated Report, the receiving stream segment of the Neuse River Estuary is
exceeding criteria for Chlorophyll-a, Total Nitrogen and Total Phosphorus at Category 4 assessment levels
for each parameter. Each parameter was rated based on > 10% of samples exceeded criteria with 90%
confidence.

A letter from the Permittee dated August 8, 2018 requested the lime addition system be removed from the
permit as it has not been used in over a decade and there are no plans for its use in the future. The lime
addition system has been removed from the system component list on the supplemental sheet of the permit.

Average monthly flow has increased from 0.92 to 1.38 MGD during this time. The annual average flow for
calendar year 2018 was 1.60 MGD or 71% of the design flow of 2.25 MGD. The permit has flow tiers of
1.9, 2.25, 2.8 and 3.5 MGD. With the receipt of the Engineer’s Certificate to expand to 2.25 MGD, the 1.9

Page 4 of 18

MGD effluent sheet has been removed from the permit. The remaining flow tier effluent sheets have been
maintained in the permit with the outfall renamed as Outfall 002.

Temperature data for the months of September 2015, and July–September 2018 were erroneously recorded
from the sample cooler, not the effluent. These data were removed from summary statistic (avera ge,
minimum, maximum) analysis, and the regional office was notified, who was already aware.

4. Instream Data Summary

Instream monitoring may be required in certain situations, for example: 1) to verify model predictions when
model results for instream DO are within 1 mg/L of instream standard at full permitted flow; 2) to verify
model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other instream
concerns. Instream monitoring may be conducted by the Permittee, and there are also Monitoring Coalitions
established in several basins that conduct instream sampling for the Permittee (in which case instream
monitoring is waived in the permit as long as coalition membership is maintained).

If applicable, summarize any instream data and what instream monitoring will be proposed for this permit
action: The permit has two sets of instream monitoring requirements: one set at the 1.9 MGD flow tier
discharging into East Prong Slocum Creek, and the other set at three locations at multiple depths for the
discharge into the Neuse River Estuary via a diffuser at all higher flow tiers. With the receipt of the
Engineer’s Certificate for the expansion to 2.25 MGD flow tier and relocation of the outfall to the Neuse
River with construction of its diffuser, the instream monitoring requirements for the 1.9 MGD flow tier
have been removed from the permit.

For the Neuse River discharge, the permit requires instream monitoring for eleven parameters at three
locations: upstream 10 ft from the diffuser center (S1), downstream 10 ft from the diffuser center (S2), and
within 10 ft beyond the end of the diffuser in line with it (S3). The instream monitorirng requirements for
the Neuse River discharge were placed in the 2012 permit modification following an extensive tidal model
developed by Tetra Tech. The sampling requirements, which include seasonal frequencies and a variety of
sample depths specific to each parameter of concern at each location, were adopted from the USMCAS
Cherry Point (NC0003816) permit, since that facility also discharges via a diffuser into the same stream
segment as Havelock WWTP. The instream sampling requirements are based on the 10 ft radius mixing
zone from the Havelock WWTP diffuser. No wiaver is available.

Instream data were reviewed from submitted DMRs for the period of May 2015 through March 2019. The
data were checked across depths and analyzed for differences among the three sample sites using Single-
Factor ANOVA with significance level (p-value) set at 0.05. Instream data review findings for each
parameter are summarized below.

Dissolved Oxygen – Dissolved Oxygen (DO) remains in the permit as a parameter of concern for aquatic
life. The receiving stream segment of the Neuse River Estuary is meting the criteria for DO (5 mg/L for
aquatic life in saltwater) according to the Final 2016 Integrated Report. Reviewed instream DO data showed
seasonal patterns of summer lows and winter highs across all stations and depths. A consistent decrease in
DO with depth was evident among all sites (Table 2), consistent with a salt wedge as described for the
receiving water of USMCAS Cherry Point diffuser discharge, located 0.5 miles downstream from the
Havelock WWTP Outfall. No significant differences were found among sites at any depth (ANOVA; all
tests p > 0.05). Surface water summer minima were below the 5 mg/L water quality standard, which could
be due to natural fluctuations in this classified tidal swamp (SB, Sw) water (15A NCAC 02B .0222).
Concurrent effluent DO averaged 7.57 mg/L with a narrower range of 5.42 – 9.25 mg/L. Therefore, the
effluent is not impacting the reciving water DO.

Temperature – Temperature remains in the permit as a parameter of concern for aquatic life. The receiving
stream segment of the Neuse River Estuary is meeting the criteria for Temperature (32°C for aquatic life in
lower piedmont and coastal plain waters) according to the Final 2016 Integrated Report. Reviewed instream
temperature data showed seasonal patterns of summer highs and winter lows across all stations and depths.
An increase in temperature was evident with depth among all sites. No significant differences were found
among sites at any depth (ANOVA; all tests p > 0.05). Surface water sumer maxima were below the water
quality stanadard of 32°C for lower piedmont and coastal plain waters (15A NCAC 02B .0222) (Table 3).
Maaximum upstream to downstream increase was 0.5°C, less than the increase standards of 0.8°C in
summer months (June – August) and 2.2°C in the remainder of the year (15A NCAC 02B .0222).
Concurent effluent temperatures averaged 21.8°C (range: 15.1 – 28.3°C). Therefore, the effluent is not
impacting the reciving water temperature.

Salinity – Salinity remains in the permit as a physiochemical parameter that affects algal bloom formation
and intensity in the Neuse River Estuary (DWR Neuse River Basinwide Water Quality Plan, 2009). The
receiving segment of the Neuse River Estuary is exceeding criteria for Chlorophyll-a (40 ug/L for aquatic
life in all state waters). Reviewed instream data found no significant differences among sites at any depth
(ANOVA; all tests p > 0.05), but showed a consistent increase in salinity with depth among all sites (Table
4), indicating a salt wedge that is consistent with salinity patterns found near the Cherry Point outfall, 0.5
miles in the Neuse River Estuary.

pH – pH remains in the permit as a parameter of concern for aquatic life. The receiving stream segment of
the Neuse River Estuary is meting the criteria for pH (4.3 SU for aquatic life in swamp water s) according
to the Final 2016 Integrated report. No significant differences were found among sites at any depth
(ANOVA; all tests p > 0.05). Few surface water measurements were outside the standard range of 6.8 – 8.5
SU (15A NCAC 02B .0222), but were consistently so across sample sites. No measurements were below
the swamp standard of 4.5 pH (15A NCAC 02B .0222) at any depth (Table 5). Compared to the surface
water data, concurrent effluent pH averaged 7.96 SU with a narrower range of 7.2 – 8.6 SU. Therefore, the
effluent is not impacting the reciving water pH.

in salinity and decrease in DO from the surface to 3 m depth.

Enterococci – Enterococci remains in the permit as a parameter of concern for aquatic life and human
health. The receiving stream segment of the Neuse River Estuary is meting the criteria for Enterococci (35
cfu/100 mL for recreational and swamp waters) according to the Final 2016 Integrated Report. Revie w of
the data showed no difference among the three sites (ANOVA; all tests p > 0.05), with monthly geometric
means largely under the tidal salt water quality standard of 35 cfu/100 mL (15A NCAC 02B .0222) (Table
6). Among the monthly geometric means, one set exceeded the standard based on the minimum of five
samples in June 2017, and was consistently high among all sites. Concurrent effluent samples were much
lower with an overall geometric mean of 1.9 cfu/100 mL (range: 1 – 38 cfu/100 mL), and no exceedences
of the monthly geometric mean based on the minimum of five samples.

Secchi Depth – The Secchi Depth is monitored 2/month June – September to measure the Photic Zone,
within which depth integrated sampling of the water column for nutrients (TN and TP) and Chlorophyll-a
is conducted. The Photic Zone is 2× the Secchi Depth according to DWR Ambient Monitoring Section’s
Intensive Survey Branch Standard Operating Procedures Manual: physical and chemical monitoring, Ver.
2.1 (NC AMS 2013). No Secchi Depths were recorded in 2018. Secchi depths averaged 0.78 m (range: 0.15
– 1.30 m) among the three sites with no differences detected among them. Calculated Photic Zone depths
averaged 1.57 m (range: 0.30 – 2.59 m).

Correspondence with the ORC revealed confusion regarding the integrated sampling depth, and review of
sample chains of custody suggest the nutrient and chlorophyll-a samples were collected at the stream
surface (0 – 6 inches depth). The permit since its modification in 2012, which introduced the instream
sampling regime for the Neuse River diffuser outfall, has not provided any definition for depth integrated
sampling or the Photic Zone. Therefore, a note has been added to Special Condition A. (4.) Instream
Monitoring Requirements in the permit to define the Photic Zone and integrated sampling depth.

Total Kjeldahl Nitrogen – The receiving section of the Neuse River Estuary is exceeding criteria for Total
Nitrogen (TN) according to the Final 2018 Integrated Report. Total Kjeldahl Nitrogen (TKN) is a part of
TN. Instream data averaged 0.83 – 0.88 mg/L (total range: 0.41 – 1.50 mg/L) among the three sites with no
statistical differences detected (Table 7). Concurrent effluent data were similar with an average of 0.97
mg/L (range: 0.27 – 1.46 mf/L). The effluent is not affecting the receiving stream TKN.

Chlorophyll-a – The receiving segment of the Neuse River Estuary is exceeding criteria for Chlorophyll-a
(40 ug/L for aquatic life in all state waters). Instream data averaged 22 – 24 mg/L (total range: 4.5 – 62.0
mg/L) among sites with no statistical differences detected (Table 7).

Nitrate-Nitrite Nitrogen – The receiving section of the Neuse River Estuary is exceeding criteria for Total
Nitrogen (TN) according to the Final 2018 Integrated Report. Nitrate-Nitrite Nitrogen (NO2+NO3) is a part
of TN. Instream data averaged 0.05-0.06 mg/L (total range: < 0.02 – 0.32 mg/L) among the three sites with
no statistical differences detected (Table 7). Concurrent effluent data were substantially higher with an
average of 2.87 mg/L (range: 0.27 – 7.32 mg/L). The effluent is not affecting the receiving stream
NO2+NO3.

Ammonia Nitrogen – The receiving stream is monitored for Ammonia-Nitrogen (NH3-N) as a component
of TN. Instream data averaged 0.06 mg/L (total range: < 0.04 – 0.29 mg/L) among the three sites with no
statistical differences detected (Table 7). Concurrent effluent data were substantially higher with an average
of 0.11 mg/L (range: < 0.04 – 1.29 mg/L). The effluent is not affecting the receiving stream NH3-N.

Total Phosphorus – The receiving stream is monitored for Total Phosphorus (TP) as this pollutant
contributes to algal blooms, expressed as Chlorophyll-a exceedences. Instream data averaged 0.15 – 0.17
mg/L (total range: 0.07 – 0.38 mg/L) with no significant differences detected among the three sites (Table
7). Concurrent effluent data were substantially higher with an average of 1.19 mg/L (range: 0.09 – 1.92
mg/L). The effluent is not affecting the receiving stream Total Phosphorus.

1 Due to a lack of guidance in the permit, samples were collected at the surface (0 – 6 inches).

Per the Division’s 2002 Instream Conductivity and Fecal Coliform Monitoring Guidance, Conductivity is
not required if the facility discharges treated 100% domestic wastewater. Since Havelock WWTP treats
100% domestic wastewater, instream monitoring for Conductivity is not needed, and therefore was not
added to the permit.

Is this facility a member of a Monitoring Coalition with waived instream monitoring (Y/N): YES, but no
provisional waiver is available for instream monitoring. The coalition had stated that it will not be
responsible for instream monitoring requirements associated with the outfall diffuser.

Name of Monitoring Coalition: Lower Neuse Basin Association (LNBA).

5. Compliance Summary

Summarize the compliance record with permit effluent limits (past 5 years): The facility has reported 12
limit exceedences over the past five years (i.e., January 2015 – December 2019). Of these, three BOD
exceedences each resulted in a Notice of Violation (NOV); the remainder were not acted upon based on
Best Professional Judgement.

Summarize the compliance record with aquatic toxicity test limits and any second species test results (past
5 years): Three Aquatic Toxicity limit violations were reported, two resulting in an NOV (January 2015,
January 2019) and one proceeding to an Enforcement Case (March 2015). The facility passed 15 of 16
quarterly chronic toxicity tests from January 2016 – October 2019, as well as all 4 second species chronic
toxicity tests, collected on December 2017, January 2018, February 2018, and March 2019.

Summarize the results from the most recent compliance inspection: The most recent inspection (compliance
evaluation), conducted 08/08/2018, found the facility to be in compliance. The inspection report noted that
the site appeared clean and properly managed, and the effluent looked good. A reconnaissance visit was
made on 9/18/2019 following Hurricane Florence. Damage was noted, with the WWTP operating under
generator power and influent was partially flowing through the filters, but the effluent looked good.

6. Water Quality-Based Effluent Limitations (WQBELs)

Dilution and Mixing Zones
In accordance with 15A NCAC 2B.0206, the following streamflows are used for dilution considerations
for development of WQBELs: 1Q10 streamflow (acute Aquatic Life); 7Q10 streamflow (chronic Aquatic
Life; non-carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).

If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): Tetra
Tech conducted nearfield dilution moleling for the facility’s proposed expansions in 2008, calculating the
90th percentile summer effluent concentration (%) at the nearfield radius for each flow tier (Table 8). The
Division selected these % effluent concentrations as the IWC for each flow tier at a 10 ft radius from the
diffuser.

Table 8. Summer effluemt plume concentrations for the 3-tiered flow expansion at Havelock WWTP
(Nearfield dilution model results, Tetra Tech 2008).

Expansion Flow Tier Model Nearfield Radius 90th Percentile
Effluent Concentration
2.25 MGD 1.6 m 14.6 %
2.8 MGD 1.7 m 15.6 %
3.5 MGD 1.8 m 16.3 %

If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): Based on
EPA guidelines, a mixing zone equal to the 10 ft water column height above the diffuser was defined as the
mixing zone radius. The Tetra Tech model was reviewed and the resulting concentrations (Table 8) were
used to define the equivalent IWC % at the boundary of the 10 ft radius mixing zone for each expansion
flow tier.

Oxygen-Consuming Waste Limitations
Limitations for oxygen-consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD = 30 mg/L for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.

If permit limits are more stringent than TBELs, describe how limits were developed: The current BOD
monthly average limits of 5.0 mg/L summer and 10.0 mg/L winter were set from speculative limits
developed in 2009 for the proposed flow expansions. The speculative BOD limits were applied to all
expansion effluent flow pages in the 2012 permit modification.

Ammonia and Total Residual Chlorine Limitations
Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of
1.0 mg/L (summer) and 1.8 mg/L (winter). Acute ammonia limits are derived from chronic criteria, utilizing
a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non-Municipals.

Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection
of aquatic life (17 µg/L) and capped at 28 µg/L (acute impacts). Due to analytical issues, all TRC values
reported below 50 µg/L are considered compliant with their permit limit.

Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: The current year-
round NH3-N monthly average limit of 1.0 mg/L was set from speculative limits in 2009. The current permit
lacks TRC limits because the facility is using UV for disinfection. Should the facility use chlorination for

Page 10 of 18

disinfection, the permit has a special condidtion that includes instructions for informing the Division,
monitoring and reporting with limits for each discharge location (13 µg/L for the discharge into the Neuse
River). The special condition has been modified by deleting text relating to the East Prong Slocum Creek
discharge.

Ammonia and TRC have been reviewed in the attached Wasteload Allocation (WLA) sheets for each flow
tier, using 7Q10 values of 0.0 cfs as the Neuse River Estuary experiences tidal flow. Current limits for both
parameters were found to be more stringent than the toxicity-based calculated results in the WLA sheets.
Therefore, no changes in limits were made in the permit.

Reasonable Potential Analysis (RPA) for Toxicants

If applicable, conduct RPA analysis and complete information below.
The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality
standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent
effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC
RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero
background; 3) use of ½ detection limit for “less than” values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.

A reasonable potential analysis was conducted on effluent toxicant data collected between May 2015 and
March 2019. Pollutants of concern included toxicants with positive detections and associated water quality
standards/criteria. Based on this analysis, the following permitting actions are proposed for this permit:
• Effluent Limit with Monitoring. The following parameters will receive a water quality-based
effluent limit (WQBEL) since they demonstrated a reasonable potential to exceed applicable water
quality standards/criteria: None at all flow tiers.
• Monitoring Only. The following parameters will receive a monitor-only requirement since they
did not demonstrate reasonable potential to exceed applicable water quality standards/criteria, but
the maximum predicted concentration was > 50% of the allowable concentration: Copper at all
flow tiers.
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring, since
they did not demonstrate reasonable potential to exceed applicable water quality standards/criteria
and the maximum predicted concentration was < 50% of the allowable concentration: Arsenic,
Cadmium, Total Phenolic Compounds, Total Chromium, Cyanide, Lead, Nickel, Selenium, Zinc
at all flow tiers.
• POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for
additional pollutants of concern.
o The following parameter(s) will receive a water quality-based effluent limit (WQBEL)
with monitoring, since as part of a limited data set, two samples exceeded the allowable
discharge concentration: None detected.
o The following parameter(s) will receive a monitor-only requirement, since as part of a
limited data set, one sample exceeded the allowable discharge concentration: None
detected.

If applicable, attach a spreadsheet of the RPA results as well as a copy of the Dissolved Metals
Implementation Fact Sheet for freshwater/saltwater to this Fact Sheet. Include a printout of the RPA
Dissolved to Total Metal Calculator sheet if this is a Municipality with a Pretreatment Program.

Toxicity Testing Limitations
Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in
accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits
issued to Major facilities or any facility discharging “complex” wastewater (contains anything other than
domestic waste) will contain appropriate WET limits and monitoring requirements, with several exceptions.
The State has received prior EPA approval to use an Alternative WET Test Procedure in NPDES permits,
using single concentration screening tests, with multiple dilution follow-up upon a test failure.

Describe proposed toxicity test requirement: Havelock WWTP is a Major POTW discharging domestic
wastewater with chronic WET limits of 15% effluent at 2.25 MGD, 16% at 2.8 MGD and 16% at 3.5 MGD,
monitored quarterly. The WET limits are based on the % IWCs designated from model results presented
for the proposed expansions and outfall relocation with diffuser to the Neuse River in 2009. Based on
receipt of the Engineer’s Certificate upgrading the plant to 2.25 MGD and outfall relocation in 2015, the
Chronic Toxicity limit of 90% special condition for discharge into East Prong Slocum Creek has been
removed from the permit.

Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply with
EPA’s mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a
wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and
industrial facilities with known mercury discharges. Given the small contribution of mercury from point
sources (~2% of total load), the TMDL emphasizes mercury minimization plans (MMPs) for point source
control. Municipal facilities > 2 MGD and discharging quantifiable levels of mercury (> 1 ng/L) will receive
an MMP requirement. Industrials are evaluated on a case-by-case basis, depending if mercury is a pollutant
of concern. Effluent limits may also be added if annual average effluent concentrations exceed the WQBEL
value (based on the NC WQS of 12 ng/L) and/or if any individual value exceeds a TBEL value of 47 ng/L.

Table 9. Mercury Effluent Data Summary.

Parameter 2015 2016 2017 2018 2019
No. of Samples 3 2 4 4 1
Annual Average Conc. ng/L 0.5 0.5 1.2 0.5 0.5
Maximum Conc., ng/L 0.50 0.50 3.20 0.50 0.50
TBEL, ng/L 47
WQBEL, ng/L 25.0 at all flow tiers

Describe proposed permit actions based on mercury evaluation: Review of effluent data from May 2015
through March 2019 revealed no annual average mercury concentrations exceeded the WQBEL, and no
individual mercury sample exceeded the TBEL (Table 9). Therefore, no mercury limit is required. Because
the facility’s permitted flow is greater than 2 MGD and fewer than two samples showed mercury levels >
1 ng/L, no mercury minimization plan (MMP) is required. The MMP permit condition was removed from
the permit.

Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation within
this permit: The Environmental Management Commission (EMC) adopted Nutrient Management Strategy
rules in December 1997, classifying the entire Neuse River Basin as Nutrient Sensitive Waters (NSW). The
point source rule (15A NCAC 02B .0234) sets Total Nitrogen (TN) discharge limits for all point source
dischargers larger than 0.5 MGD.

Page 12 of 18

The rule also allows dischargers to form a group compliance association and work together to reduce
nitrogen; this option allows the association members added flexibility in controlling nitrogen discharges.
At the same time, the association is subject to a group NPDES permit ensuring that the association and its
members are accountable if they exceed the applicable nitrogen limits.

Under this rule, there are three types of TN limit in the Neuse:
1. The individual limits in the discharger’s individual permit,
2. The aggregate limit in an association’s group NPDES permit, and
3. The individual allocations/limits for each Association member, also in that Association permit.

A discharger may be subject to the first type of limit, or to the second and third, but never to all three at the
same time. The discharger is first subject to the TN limit (if any) in its individual NPDES permit. If the
discharger becomes a co-permittee to a compliance association’s group NPDES permit, it is then governed
by the TN limits in that permit. If the association complies with its group TN limit in a given year, all
members are deemed to be in compliance with their individual allocations/limits in the group permit. If the
association exceeds its limit, the members then become subject to their individual allocations/limits as well.

Regardless of which permit governs a TN discharge, allocations/limits will likely change over time as the
dischargers purchase, sell, trade, lease, or otherwise transfer nitrogen allocations. The Division wil modify
the affected permits as necessary to ensure that the limits are kept up-to-date and reflect any such
transactions.

The permit includes nutrient limits consistent with the Nutrient Management Strategy rule (15A NCAC
02B .0234). Under the rule, the City of Havelock receives a TN load limit of 21,400 lb/yr, a calendar year
limit. The current facility annual TN Load mass limit is a fixed allocation and will remain set at 21,400
lbs/yr regardless of which effluent limit page is active. Monthly calculation and reporting of TN Load mass
is required on all efflueint limit pages. There are no plans for further regionalization.

The City of Havelock is a member of the Neuse River Compliance Association (NRCA). So long as it
remains a co-permittee member, it is deemed to be in compliance with the TN limit in this permit, and its
TN discharge is governend instead by the Association’s group NPDES permit (NCC000001), issued
December 30, 2013; most recently modified December 21, 2017. The group’s permit estuary TN limit is
1,187,213 lb/yr, of which the facility’s estuary TN allocation/limit is 21,400 lb/yr, the same as in its
individual permit.

As reported in the NRCA 2018 Annual Report, the City of Havelock had leased 6,000 lbs estuary TN from
the City of Goldsboro in 2018. Because the lease is a temporary transaction within the Association, it does
not affect the facility’s individual permit TN load allocation/limit. Havelock had exceeded its individual
TN allocation in 2018 due to facility issues and record rainfall from Hurrican Floren ce, but The NRCA’s
2018 total loading was 556,567 lb TN, well below its total estuary limit. Therefore, Havelock’s 2018
exceedence does not represent a violation of its individual permit.

To ensure that the facility can meet its TN load limits with the two flow expansions, a Special Condition
was added to the permit requiring an Authorization to Operate based on the Permittee’s demonstration that
it can meet the TN limits.

In the current permit, effluent TP limit is 2.0 mg/L quarterly average for all flow tiers beyond 1.9 MGD,
based on membership in the NCRA. Termination of membership will automatically assign 1.0 mg/L as the
TP monthly limit. This conditional requirement is based on the Neuse Nutrient Strategy rules for expanding
facilities (15A NCAC 02B .0234(8)(g)). A conditional footnote narrative for the TP concentration limit is
included in each flow tier effluent limit page. No changes are proposed.

Other WQBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: NA.

If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall
comply with in order to protect the designated waterbody: NA.
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with 15A
NCAC 2H.0107(c)(2)(B), 40CFR 122.47, and EPA May 2007 Memo: NA.

If applicable, describe any water quality standards variances proposed in accordance wit h NCGS 143-
215.3(e) and 15A NCAC 2B.0226 for this permit renewal: NA.

7. Technology-Based Effluent Limitations (TBELs)

Municipals (if not applicable, delete and skip to Industrials)
Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/L
BOD5 /TSS for Monthly Average, and 45 mg/L for BOD5/TSS for Weekly Average). YES; the current BOD
limits of 5.0/10.0 mg/L summer/winter monthly average at 2.25, 2.8 and 3.5 MGD were originally set as
speculative limits for the proposed expansion in 2009. They were then placed in the 2012 permit
modification.

Are 85% removal requirements for BOD5/TSS included in the permit? YES.

If NO, provide a justification (e.g., waste stabilization pond). NA.

8. Antidegradation Review (New/Expanding Discharge)

The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegradation
review in accordance with 15A NCAC 2B .0201. Each applicant for a new/expanding NPDES permit must
document an effort to consider non-discharge alternatives per 15A NCAC 2H .0105(c)(2). In all cases,
existing instream water uses and the level of water quality necessary to protect the existing use is maintained
and protected.

If applicable, describe the results of the antidegradation review, including the Engineering Alternatives
Analysis (EAA) and any water quality modeling results: NA.

9. Antibacksliding Review

Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(l) prohibit
backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a
reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations
may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).

Are any effluent limitations less stringent than previous permit (YES/NO): NO.

Page 14 of 18

10. Monitoring Requirements

Monitoring frequencies for NPDES permitting are established in accordance with the following regulations
and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2) NPDES
Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance, Reduced
Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best Professional
Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not considered
effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti-backsliding
prohibitions would not be triggered by reductions in monitoring frequencies.

With the permit application, the Permittee requested reduced monitoring frequencies for TSS, Ammonia-
N (NH3-N) and Enterococci target parameters based on DWR Guidance Regarding the Reduction of
Monitoring Frequencies in NPDES Permits for Exceptionally Performing Facilities. Review for eligibility
found:
• No civil penalty enforcement for any of the three target parameters in the past three years (i.e.,
from April 2016 through March 2019);
• No limit violations for any of the target parameters in the previous year (i.e., from April 2018
through March 2019);
• The facility is not operating under a Special Order by Consent (SOC) for noncompliance of any
target parameter;
• The facility is not on EPA’s quarterly non-compliance report (QNCR) for any target parameter.

Review of effluent data from April 2016 through March 2019 for the three target parameters revealed that
the data criteria of 1) three-year mean below 50% of the monthly average limit, and 2) no more than 15 (20
for Enterococci) sampling results greater than 200% of that limit, were met (Table 10):

From the review, MFR criteria for all parameters are met. Therefore, the reduced monitoring frequencies
of 2/week have been added to the permit for TSS, Ammonia-N, and Enterococci.

For instream monitoring, refer to Section 4.

11. Electronic Reporting Requirements

The US EPA NPDES Electronic Reporting Rule was finalized on December 21, 2015. Effective December
21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports (DMRs)
electronically. Effective December 21, 2020, NPDES regulated facilities will be required to submit
additional NPDES reports electronically. This permit contains the requirements for electronic reporting,
consistent with Federal requirements.

Nothing about your sampling requirements has changed. As of May 1st, all effluent data from outfall 001 will be entered

Neuse River Estuary [AU# 27-(104)bl
Bend TMDL Segment)
The Neuse River Estuary [AU# 27-(104)b; SB; Sw; NSW] from a line across Neuse River from
1.2 miles upstream of Slocum Creek to 0.5 miles upstream of Beard Creek to a line across Neuse
River from Wilkinson Point to Chevy Point (bend model segment) (10,756.9 saltwater acres) is
Impaired for aquatic life due to high chlorophyll a and high pH levels throughout this TMDL
segment (Figure 25 and 26). Chlorophyll a was evaluated at all but a single station (JA89,
Cherry Point) within this segment. All 6 of the stations assessed exceeded the 40µg/1 standard
between 12 percent (JAI 11; Minnescott Beach) and 25 percent (JAI 07, Cherry Point Channel)
of the time. The highest recorded chlorophyll a level was 236 µg/l at site JA87 (Arapahoe).
These waters experienced high pH levels, with 6 of the 7 stations in this segment exceeding the
state pH standard of no greater than 8.5 more than 10 percent of the time. These 6 stations
exceeded the standard between 12 and 29 percent of the time. Station JA89 (Cherry Point) was
the only station in this segment not to exceed the 10 percent criterion; however, it exceeded the
standard 9.2 percent of the time. This is a new impairment for this segment and will be added to
the 2008 303(d) list (category 5). Elevated pH levels are directly related to elevated
phytoplankton activity in this segment of the estuary as well.
This segment will remain in category 4a (impaired) on the 2008 Integrated Report for the
chlorophyll a standard violations.
Neuse River Estuary AU# 27- 118 al 27- 118 ala & 27- 118
(Lower TMDL Segment)
The Neuse River Estuary [AU# 27-(118)al; SA; HQW; NSW] from a line across Neuse River
from Wilkinson Point to Cherry Point to a line across the river at Adams Creek to Wiggins Point
(17,135.4 saltwater acres), Neuse River Estuary at Camp Don Lee [27-(118)ala; SA; HQW;
NSW] swim beach at Camp Don Lee (Saltwater acre) and Neuse River Estuary [AU# 27-(118)f;
SA; HQW; NSW] the prohibited area at Cherry Branch Minnesott Ferry Landing south side of
river (93.5 saltwater acres) is Impaired for aquatic life due to high chlorophyll a throughout this
segment (Figure 26). Chlorophyll a was assessed at 2 of the 3 stations and the exceedances
occurred in 18 and 11 percent of the samples collected at JA90 (Minnesott Beach) and JA92
(Janeiro) respectively.
On an individual site basis, the highest recorded chlorophyll a level was 158 µg/l at site JA90
(Minnesott Beach). Chlorophyll a levels dropped linearly as the sampling stations moved down
the estuary towards the Pamlico Sound. The pH followed a similar trend.
This segment was not previously impaired for chlorophyll a violations; however, it was included
as part of the overall TMDL nutrient management strategy. It will remain in category 4a
(impaired) of the 2008 Integrated Report.
Neuse River Estuary at Camp Don Lee [27-(118)ala] is also Impaired for recreation due to
elevated enterococcus bacteria levels detected by the DEH recreational beach water quality
monitoring program. This impairment is discussed in greater detail in the Neuse River Estuarine
Recreational Assessment below. This segment will be added to the 2008 303(d) (category 5) list
of impaired waters.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Stewart White inspected the facility and found the WWTP site clean and properly managed. James
Carter,ORC was very helpful during the inspection. He has not been employed with Havelock long.
James appears to be a dedicated operator with a bright future for Havelock's WWTP.
The 2017 Annual Report was advertised on the town's web site and a copy avalible on file.
The Effluent looks great!
The solids are too high in the aeration basin thus generating a lot of sludge.The ORC stated they were
looking into better solids handling processing options. Again Effluent looks great.

Huricane Florence did a lot of damage to Havelock. There were many trees down taking down power
lines wide spread. The WWTP was on generator power. Influent was partially flowing threw the filters
9/20/18. James Carter ORC and staff did an amazing job under the conditions of Florence. Hurricance
winds 85-105 MPH hit the plant. A tree came down on the UV system but UV disinfection remains
operational. Effluent looked good.Many thanks to the WWTP staff maintaining the integrity of the plant.

Hey Gary,
Yes these are also Method 1631E and should be in ng/L. The a-DMR needs to be corrected to reflect ng/L. Thank you
for finding and making sure they are expressed correctly.

Thanks James,
I'll add them to my spreadsheet. This is the dataset I have from the submitted DMRs. Are these also tested via Method
1631E and are they ng/L?

James,
I have attached the 2018 & 2019 data and COC Forms for 1631 Mercury for Havelock. This is what was in our archive.
When you report this, the units should be ng/I. Very easy to make this error since this is the only conventional test
reported in these units.
Please see the result pages. Under PARAMETERS, the test is listed as Method 1631 E and the unit of measure is ng/I.
Let me know if you need further assistance. Probably a good idea just to forward the results so the State personnel can
see.

Thanks for confirming the units. However, the method for low level mercury is EPA 1631E, which reports in ng/L. Can
you check your lab reports to confirm is this method or another is being used for Mercury?

Thanks again and have a good weekend,
Gary

Dear James,
I'm now reviewing your facility's mercury data and see all are expressed in ug/L, yet reported as low level mercury
(Parameter code: COMER in DMR). Can you tell me that method is being used to analyze your samples for mercury?

PART
SPECIAL CONDITIONS
A.(1.) DEFINITIONS
(a.) Active TN Allocation: Allocation that is included in calculation of TN Load Limits. Allocation
held by a permittee is active by default but may be designated as reserve allocation by the
Division or at the request of the permittee. (See also Reserve TN Allocation.)
(b.) Allocation (or "TN Allocation"): (1) The mass quantity (as of TN) that a discharger or group of
dischargers (such as the Association) is potentially allowed to release to surface waters in
accordance with the Neuse River rule. TN Allocations may be expressed as Estuary TN Allocation
or as the equivalent Discharge TN Allocation; also as active or reserve allocation. (2) In practice,
the term can refer to a permittee's or group's allocation as a whole or to some lesser quantity.
(c.) Association: The Neuse River Compliance Association, a not -for -profit corporation comprised of
NPDES-permitted dischargers in the Neuse River Basin; established voluntarily under the Neuse
Wastewater rule to meet the aggregate Estuary TN Allocation of its Co-Permittee Members.
(d.) Co-Permittee Members: Those NPDES dischargers that for a given calendar year are members of
the Association and are listed in Appendix A of this permit.
(e.) Discharge TN Allocation: TN Allocation specified as applying at the point of discharge (or "end -
of -pipe").
(f.) Discharge TN Load: Actual TN Load measured at a Co-Permittee Member's point of discharge
(or "end -of -pipe").
(g.) Estuary: The Neuse River estuary, which extends from approximately Streets Ferry to the
Pamlico Sound.
(h.) Estuary TN Allocation: TN Allocation specified as applying at the estuary. A Co-Permittee
Member's Estuary TN Allocation is equivalent to its Discharge TN Allocation multiplied by the
applicable Transport Factor.
(i.) Estuary TN Limitation: The sum of active TN allocations held by the Association and its Co-
Permittee Members (group limit) or a Co-Permittee Member (individual limits), as listed in
Appendix A of this permit.
Estuary TN Load: TN Load estimated to be delivered to the estuary. A Co-Permittee Member's
Estuary TN Load is equivalent to its Discharge TN Load multiplied by the applicable Transport
Factor.
(k.) Limitation (or "TN Limit(ation)" or "TN Load Limitation}"}: The mass quantity of TN specified
in an NPDES permit as the maximum that an individual discharger or group of dischargers is
authorized to discharge to surface waters. The TN Limitation is the sum of active allocations held
by an individual Co-Permittee Member (in the case of individual limitations) or held in the
aggregate by the Association and its Co-Permittee Members (in the case of the group limitation).
For the purposes of this permit, TN Load Limits are expressed in terms of Estuary TN Load.
(1.) Load (or "TN Load"): The actual mass quantity (as of TN) that a discharger or group of
dischargers releases into surface waters of the Neuse River Basin. TN Loads may be expressed as
Discharge TN Load or as the equivalent Estuary TN Load.
(m.) Neuse Wastewater Rule: The Neuse River Basin Nutrient Sensitive Waters Management Strategy:
Wastewater Discharge Requirements rule (T15A NCAC 2B .0234)
(n.) Regionalization: The consolidation of wastewater collection and/or treatment systems that
results in the elimination of one or more NPDES-permitted discharges.
(o.) Reserve TN Allocation: Allocation that is not included in calculation of TN Limits. The Division
may designate allocation as reserve when water quality -based limits established to prevent

Permit No. NCC000001
Part I, Page 2 of 5
localized impacts render that allocation inactive; when treatment of the allocation as active would
be inconsistent with the Neuse Wastewater rule. (See also Active TN Allocation.)
(p.) Total Maximum Daily Load (of TMDL): (1) Generally, the allowable load of a pollutant that can
be discharged to a water body without causing loss of that water's designated uses. (2) In the
context of this permit, refers to Phase II of the Total Maximum Daily Load for Total Nitrogen to the
Neuse River Estuary, North Carolina, approved by the U.S. Environmental Protection Agency on
March 19, 2002, and subsequent revisions approved by the EPA.
(q.) Total Nitrogen (TN): The sum of the organic, nitrate, nitrite, and ammonia species of nitrogen in
a water or wastewater.
(r.) Transport Factor: Fraction of the TN in a discharge that is predicted to reach the estuary, as
determined by the Division.
(s.) Water Qpality-Based Effluent Limitations (WQBELs): Limitations calculated specifically to
ensure that a discharge does not cause an exceedance of water quality standards either in the
vicinity of the discharge or further downstream. In the context of this permit, applies only to
Total Nitrogen.
A.(2.) CO-PERMITTEES AND TN ALLOCATIONS
(a.) Co-Permittees to this permit shall be the Neuse River Compliance Association (the "Association")
and each of its Co-Permittee Members. The Co-Permittee Members, the Transport Factors
assigned to each, the Members' individual TN allocations, and the Association Estuary TN
Allocation shall be as listed in Appendix A, which is hereby incorporated into this permit in its
entirety.
(b.) Upon timely and proper notification by the Association as described elsewhere in this permit, the
Division shall revise Appendix A to incorporate changes in Association membership, allowable
changes in TN Allocations, or reapportionment by the Association.
(i.) Changes in membership.
(A) Enrollment. In the event that a discharger is admitted to the Association, the Division
shall add the discharger and its TN Allocation to Appendix A as a Co-Permittee
Member and adjust the Associations Estuary TN Allocation accordingly.
(B) Termination. In the event that a Co-Permittee Member's membership is terminated,
the Division shall delete the departing Member and its TN Allocation from Appendix
A and adjust the Associations Estuary TN Allocation accordingly.
(ii.) For the purposes of this permit, allowable changes in TN Allocations include those resulting
from purchase of allocation from the Wetlands Restoration Fund or other authorized source;
purchase, sale, trade, or lease of allocation among the Association, its members, and non-
member dischargers; regionalization; and other transactions approved by the Division.
(iii.) The Association and its Co-Permittee Members may reapportion their TN Allocations
among themselves; however, the Division shall only incorporate'the corresponding changes
into Appendix A when specifically requested in writing by the Association and after such
changes have been incorporated into the affected individual permits.
(c.) For the purposes of this permit, Association membership, individual or Association TN
Allocations and associated limits, and allocation status (active or reserve) are effective on a
calendar year basis, and any changes shall become effective no sooner than January 1 of the
following calendar year.
A.(3.) EFFLUENT LIMITATIONS
(a.) Beginning on the effective date of this permit and lasting no later than the expiration date, the Co-
Permittees are authorized to discharge Total Nitrogen (TN) from the treatment facilities listed in
Appendix A subject to the following effluent limitations.

Permit No. NCC000001
Part I, Page 3 of 5
(i.) Association TN Limitation. In any calendar year, the Association's Estuary TN Load shall
not exceed its Estuary TN Limitation as specified in Appendix A.
Association TN Limitation: For any calendar year,
Association Estuary TN Load < Association Estuary TN Limitation
where
Association Estuary TN Load (or Limitation) = Sum of Estuary TN Loads (or Limitations)
for All Co-Permittee Members and the
Association
(ii.) Co-Permittee Member TN Limitations. In any calendar year, a Co-Permittee Member shall
be in compliance with its Estuary TN Limitation in Appendix A if:
(A) the Association Estuary TN Load complies with the Association Estuary TN
Limitation in Appendix A, or
(B) in the event that the Association Estuary TN Load exceeds its Estuary TN Limitation,
the Co-Permittee Member's Estuary TN Load does not exceed that Member's Estuary
TN Limitation in Appendix A.
(b.) Individual WOBELs: If the Division determines that a Co-Permittee Member's TN discharge has
reasonable potential to cause localized water quality impacts, it may determine an individual
water quality -based TN Limit for the Member pursuant to Neuse rule (specifically, T15A NCAC
02B .0234(6)(c), (7)(g), and (8)(h)). The Division will then propose to incorporate the new limit into
the Member's individual NPDES permit and this group permit according to standard permitting
procedures. Once the individual WQBEL becomes effective in this group permit, the Member is
subject to the new limit in lieu of the Association TN Limit. If a Member's individual WQBEL is
less than its active TN allocation, the difference is designated as reserve allocation.
(c.) Other Individual Limitations. In the event that a Co-Permittee Member's membership in the
Association is terminated, the departing Member shall no longer be eligible for coverage under
this permit and shall become subject to the TN limitation set forth in its individual NPDES
permit.
(i.) Termination of co-permittee status and re -imposition of a discharger's individual TN
limitation shall become effective only at the beginning of a calendar year (January 1).
(ii.) The Association shall notify the Division if it determines that any Member will depart at the
end of a calendar year and shall provide an accounting of all allowable changes in the
Member's TN Allocation since the most recent issuance of the departing Member's
individual NPDES permit.
(iii.) Upon receipt of the notification and accounting described above, the Division shall modify
the TN limitation in the departing Member's individual NPDES permit as necessary,
effective January 1 of the succeeding year, to reflect all allowable changes in the outgoing
Member's TN Allocation and shall also modify Appendix A of this permit accordingly.
A.(4.) MONITORING REQUIREMENTS
(a.) Each Co-Permittee Member shall continue to monitor its discharge(s) and report the results to the
Division as specified in its individual NPDES permit.
(b.) The Association shall assemble the results of its Co-Permittee Members and report the combined
results to the Division as specified in Condition A.(5.), below.

Permit No. NCC000001
Part I, Page 4 of 5
A.(5.) REPORTING REQUIREMENTS

Association shall request modification of this permit to reflect changes in membership or TN
allocations to become effective in the following calendar year. The Association may revise its
request through its Mid -Year Report or other proper written notification.
(c.) Mid -Year Report. No later than September 30 of each year, the Association shall submit a mid-
year report to the Division. The report shall include, ata minimum, the following information:
(i.) for the period beginning July 1 of the preceding year and ending June 30 of the current year,
a report, for informational purposes only, of each Co-Permittee Member's Discharge and
Estuary TN Loads and the Association's Estuary TN Load; this requirement is waived if the
Associations Estuary TN Load for the previous calendar year was less than 80 percent of
the TN Limitation in that year; and
(ii.) notification of any further changes in Association membership or TN Allocations to become
effective in the following calendar year.
(d.) Year -End Report. No later than March 31 of each year, the Association shall submit a year-end
report to the Division. The report shall include, at a minimum, the following information for the
previous calendar year:
(i.) for the period from January 1 through December 31 of the preceding year, a report of each
Co-Permittee Member's Discharge and Estuary TN Loads and the Association's Estuary TN
Load;
(ii.) a summary of changes in Association membership; and
(iii.) a summary of all regionalization of discharges, purchases, sales, trades, leases, and other
transactions affecting the TN Allocations of the Association or its Co-Permittee Members.
(e.) Five -Year Report. No later than July 1, 2018, in conjunction with application for renewal of this
permit, the Association shall submit a 5-year report to the Division. The report shall include, at a

discharges;
(iv.) a general assessment of progress made; and
(v.) a description of efforts planned for the upcoming permit term, if known.
A.(6.) COMPLIANCE
(a.) In the event that the Association exceeds its Estuary TN Limitation in a given calendar year, the
Association shall make offset payments for that excess TN at a rate consistent with the Nutrient
Offsets Payment rule (15A NCAC 213.0240) or such other rate as may be adopted by the
Commission. Payment shall be made no later than May 1 of the year following the exceedance
and shall be submitted to:

conditions of this permit nor shall it relieve the Association or its Co-Permittee Members of their
responsibility to comply with any other applicable federal, state, or local law, rule, standard,
ordinance, order, judgment, or decree. In determining the amount of any penalty to be assessed
against the Association or its Co-Permittee Members, the Division shall credit the Association or
its Members for any offset payments submitted by each, provided that the Association includes
with the offset payment submittal an accounting of each Member's contribution.
(f.) No Co-Permittee Member shall be liable for any other Co-Permittee Member's non-compliance
with this permit.

Footnotes:
1. Craven County is currently leasing Total Nitrogen (rN) allocation from the NRCA until the proposed facility is constructed and a determination is made as to the allocation
needed for its discharge. See footnote 3 regarding the TN allocation held by the NRCA.
2. Progress Energy's Lee Steam Plant is allowed a baseline TN load of 3,260 lb/yr at its Outfall 001(2,282 lb/yr at the estuary). Progress leased additional allocation from the
NRCA to ensure coverage for TN discharges from its Rotamix system through 2013. It ceased operation of that system in 2012. The allocations listed in this table and the
amounts to be reported by Progress under this permit pertain strictly to any load in excess of the baseline allowance.
3. In 1999, Burlington Industries deeded its TN allocation (since adjusted to 24,400lb/yr at the estuary) for use by the Association and its Co-Permittee Members. At present,
the allocation is a group holding assigned to this group permit and is not associated with any individual permit. Unless noted otherwise in this Appendix A, the entire
amount of the allocation is active and is included in the Association Estuary TN Allocation and Limit.
4. Allocation purchased and held in reserve for future use by the co-permittee member.
5. Allocation held in reserve by the co-permittee member, under the Falls Lake nutrient strategy, a more stringent TN limit was set in its individual permit, effective CY2016.
Effective: January 1, 2018.

APPENDIX B
POINT SOURCE FACILITIES ASSIGNED TOTAL NITROGEN ALLOCATIONS
NEUSE RIVER BASIN
The following is a list of all treatment facilities that, as holders of individual NPDES permits in 1995,
are assigned a Total Nitrogen (TN) allocation pursuant to state rule T15A NCAC 2B .0234, Neuse River
Basin Nutrient Sensitive Waters Management Strategy - Wastezvater Discharge Requirements, adopted
December 1997 and revised October 2002.
The rule establishes an aggregate Estuary TN Allocation of 1.64 million pounds TN per year for these
facilities and prescribes how the allocation is to be divided among the individual facilities. The
allocations, individual and aggregate, become effective with calendar year 2003.
The Total Maximum Daily Load for Total Nitrogen to the Neuse River Estuary, North Carolina, approved by
the USEPA Region 4 in July 1999, also concludes that this aggregate allocation is the maximum
allowable contribution from point source dischargers to the Neuse River estuary.

Re: NPDES Permit No. NCC000001
Annual Report for 2018
Dear Linda:
The Neuse River Compliance Association is pleased to submit its 2018 annual report as required in
the above referenced permit. As included in the attached report, the co-permittee members
delivered a total of 556,567 pounds of total nitrogen to the Neuse Estuary during calendar year
2018, approximately 47% of the permit limit of 1,187,213 pounds for 2018.
We are very proud of the continued accomplishments of the Association and the efforts made by
our members to control nitrogen loading to the Neuse River Estuary.
We hope that the enclosed report provides the detailed information that the Division has requested.
If you have any questions, or if you need any further information, please contact our Executive
Director, Haywood M. Phthisic, III, at 919.796.8049.
Sincerely,

Short Term Lease Aireements in 2018 -
* Craven County leased 4,280 lbs. of estuary nitrogen for their facility, NPDES #
NC0089460, for 2018. The water treatment facility began operations in October, 2017.
The facility discharged a total of 3,897 lbs. for 2018. The lease Craven County had with
the NRCA has ended and Craven County is leasing from members of the association to
meet their nitrogen allocation requirements. Craven County leased from Dow — Dupont,
Inc. of Kinston.
* CWS Systems, Inc. leased 2,500 estuary pounds of nitrogen from Contentnea MSD
for 2018 for its facility at Fairfield Harbor (NC0033111). The facility at Fairfield Harbor
experienced above average rainfall in 2018 but remained compliant with its nitrogen
allocation at 97%.
* Town of LaGrange leased 5,000 estuary pounds of nitrogen from Contentnea MSD
for 2018 for its facility, NPDES # NC0021644. The Town was compliant in 2017 but the
record rainfall in 2018 caused the facility to exceed its allocation. The Town continues
has make improvements to the collection system as funds become available.
* Town of Kenly leased 1,000 estuary pounds of nitrogen from Dow — Dupont, Inc. for
2018 for its facility, NPDES # NC0064891. The Town continues to recover from issues
at the facility in 2017 and experienced record rainfall for 2018. The facility should be
compliant with its nitrogen allocation in 2019.
" Neuse Colony (Aqua, N. C.) leased 600 estuary pounds from Dow — Dupont, Inc. for
2018 for its facility, NPDES # NC0064564. The facility was compliant with its nitrogen
allocation in 2017. This facility serves a large residential development that is experiencing
above average growth.
* City of Havelock leased 6,000 estuary pounds from the City of Goldsboro for 2018 for its
facility, NPDES # NC0021253. The City was compliant in 2017 with its nitrogen
allocation. Issues at the facility in the first half of 2018 caused the exceedance coupled
with record rainfall (and hurricane Florence). The facility should be compliant with its
