Subject: NPDES Permit Issuance
Permit# NCO086819
NE Brunswick Regional WWTP
Brunswick County
Dee Freeman
Secretary
The Division of Water Quality is forwarding herewith the Final NPDES permit for the Northeast Brunswick Regional
WWTP. This permit renewal, which incorporates a phased expansion to 3.8 MGD, is issued pursuant to the requirements
of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated October 15, 2007 (or as subsequently amended).
This Final Permit incorporates the following significant changes from your previous permit:
• Supplement to Cover Permit Sheet- delete outdated reference to effluent reuse at Magnolia Greens golf
course, which has established its own irrigation system. However, it is expected that the Permittee will
continue to seek viable reuse candidates.
• Effluent Sheet A(1)- delete outdated fecal coliform language. Add Weekly Average Enterococci bacteria
limit of 276/100 m] based on Federal criteria.
• Effluent Sheet A(1)- delete total residual chlorine (TRC) language, since facility utilizes UV disinfection.
• Add new Effluent Sheet A(2) for proposed Phase 1 expansion to 2.475 MGD, and Effluent Sheet A(3) for
proposed Phase 2 expansion to 3.8 MGD. This proposed expansion received a Finding of No Significant
Impact (FONSI) on August 16, 2011.
• Add more stringent TSS limits of 10 mg/l Monthly Average and 15 mg/1 Weekly Average to reflect
requirements for Primary Nursery Area (PNA) designated waters, which fall under High Quality Water
requirements (per 15A NCAC 2B.0224). The facility is already capable of treating to reuse standards.
• Add more stringent minimum effluent DO limit of 6 mg/l to reflect requirements for PNA/HQW waters
per 15A NCAC 2B.0224.

• Add quarterly monitoring for copper and zinc to all Effluent Sheets, based on results of a Reasonable
Potential Analysis (RPA). This monitoring must be conducted in concert with the quarterly toxicity
testing.
• Add quarterly monitoring for mercury to all Effluent Sheets utilizing analysis by low level mercury
Method 1631E. Current analysis by EPA Method 245.1 does not provide proper comparison to water
quality standards.
• Reduce the Effluent Pollutant Scan.frequency from annually to three times per permit term. This permit
specifies that the pollutant scans must be conducted during calendar years 2013, 2014, and 2015, with
data reported to the Division by December 31 s' of each designated sampling year.
• Please note that there are lower laboratory quantitation levels available for cadmium (PQL = 1 ug/1),
nickel (PQL= 2 ug/1), and silver (PQL= 5 ug/1). These lower quantitation levels should be utilized in
future NPDES sampling to provide proper comparison to surface water quality standards.
• Please note that upon expansion to 3.8 MGD, this facility will be re -rated to a Class 4 WWTP which
requires more frequent monitoring and a Class 4 ORC.
If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable to you, you
have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This
request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and
filed with the office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless
such a demand is made, this permit shall be final and binding.
Please take notice that this permit is not transferable except after notice to the Division of Water Quality. The Division
may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to
obtain other permits which may be required by the Division of Water Quality, the Division of Land Resources, the Coastal
Area Management Act, or any other federal or local governmental permit.
If you have any questions on this permit, please contact Tom Belnick at 919-807-6390.

A. 14.1 ACUTE TOXICITY PASS/FAIL PERMIT LIMIT 1 RTRLYI
The permittee shall conduct acute toxicity tests on a quarterlu basis using protocols defined in
the North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining
Acute Toxicity In A Single Effluent Concentration" (Revised -July, 1992 or subsequent versions).
The monitoring shall be performed as a Fathead Minnow (Pimephales promelas) 24-hour static
test. The effluent concentration at which there may be at no time significant acute mortality is
90% (defined as treatment two in the procedure document). Effluent samples for self-
monitoring purposes must be obtained during representative effluent discharge below all waste
treatment. The tests will be performed during the months of January, April, July and
October.
All toxicity testing results required as part of this permit condition will be entered on the
Effluent Discharge Monitoring Form (MR -1) for the month in which it was performed, using the
parameter code TGE6C. Additionally, DWQ Form AT -2 (original) is to be sent to the following
address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section
no later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/ physical
measurements performed in association with the toxicity tests, as well as all dose/response
data. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity
monitoring is required, the permittee will complete the information located at the top of the
aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number,
county, and the month/year of the report with the notation of "No Flow" in the comment area of
the form. The report shall be submitted to the Environmental Sciences Section at the address
cited above.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing,
this monthly test requirement will revert to quarterly in the months specified above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
then monthly monitoring will begin immediately until such time that a single test is passed.
Upon passing, this monthly test requirement will revert to quarterly in the months specified
above.
Should any test data from either these monitoring requirements or tests performed by the
North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this
permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as
minimum control organism survival and appropriate environmental controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no
later than the last day of the month following the month of the initial monitoring.

Pam,
I was out of the office yesterday and just read your email.
Regarding the RPA's at the expanded flows - Please note that this is a facility discharging
to tidal waters so there is no allowance for dilution. Notice the IWC's are 100%.
Therefore, the numbers (limits and rpa) will not change with the expanded flows. I have
reprinted the RPA at 2.475 and 3.8 MGD and attached all three.
Pretreatment Programs - Modified or Full, are not addressed in the NPDES.permit. All aspects
of the Pretreatment program are handled separately. If you are looking for NC's definition of
a modified program it can be found under 15A NCAC 02H .0904 (b) and is listed below.
(b) The Division may allow a control authority having a combined permitted flow less than or equal to two i
gallons per day and less than fixe sipi5cant industrial users to &-%vkp and implement a modified pr+etr+e+atment ps
that encompasses a portion of the , in Rules .0905 and .0906 of this Section, as designated by the D
Directs. In malting the decision to allaw modified prat program development and implemenadon. the D
Director may consider fictors including percent industrial flow. i Anuial waste cl~arracoeristics, compliance stamp
facility. and the potential for' industrial growth
B. 6 and base -neutrals - The table under B.6 appears to be completed. The only parameter not
addressed is TRC and this is because the facility uses UV for disinfection, no sampling for
TRC is required. A review of the files shows that the City performed four Effluent Pollutant
Scans which included volatiles, acids and base -neutrals. Effluent samples were taken on 5-12-
2010, 8-25-2010, 11-10-2010, and 1-5-2011. All four scan results are attached and it confirms
that the number of samples is indeed the same as the others.
Regarding the additional flow - DWQ does have an approved Engineering Alternatives Analysis
(EAA) which specifies their request for a phased expansion from 1.65 to 2.475 to 3.8 MGD.
However, I can see in Part B, B.5. d. the expansion from 1.65 MGD to 2.475 MGD is addressed
(825,000 GPD expansion) but the additional expansion to 3.8 MGD should have been added. I
have a phone call into WK Dickson (City's consultant) and will have them revise the design
flow, under A. 6. a. to include the existing flow plus the proposed 2.475 and 3.8 MGD as well
as the schedule under B. 5. I would think I could get this simple correction from the City by
the end of the week unless you think the EAA is sufficient.(? yes - no)
Except for the last item, I believe this addresses all of your concerns. All the attachments
are upside down, sorry!. As far as the 90 day extension, I am waiting to hear back from the
consultant, is it possible to give me two days to get the revised page with a letter from the
City?
Please let me know if you have any additional questions on this.
Thanks,
Julie

Subject: Request for data for draft permit under reveiw. Cape Fear RB; current Priority
Watershed.
Tom, I understand from your voice mail that you are on vacation, so I
will also address this to Julie just in case she can assist.
My comments pertain to the draft permit for NCO086819, N.E. Brunswick
Regional WWTP, received 9/19/2011.
Julie,
The application we received requests renewal of the permit for flow of
1.65 MGD. The fact sheet indicates the facility applied for an expansion
and that the proposed expansion was subjected to extended reviews and a
positive SEPA/FONZI determination was issued. However, the package sent
to Region 4 for review lacks some important data. Title 40, Part 122,
Subpart B - Permit Application and Special NPDES Program Requirements
requires an application for these additional flow values. If those
applications are in house, please forward copies for our files. Also,
needed to complete the submitted review package are the reasonable
potential analyses (RPA) performed for those expanded flows. They were
not included in this package.
Data is also missing from the tables for Part B.6. of Form 2A. and
Base -Neutral compounds in Part D for the renewal (at 1.65 MGD). It
appears that the "Number of Samples" column was intended to extend to
the end of the form, but we have no way of confirming that without
either your confirmation or copies of the actual data sheets.
The fact sheet states that the facility is operating a modified
2
Pretreatment program, but the draft permit does not address a
Pretreatment program at all. Can you also forward that part of the draft
permit? I realize some of that language is in the recently revised
standard conditions, but a "modified" program should include some
definitive language to address that.
Since Tom is away from the office and these seem to be substantive
comments, it may be best to request a 90 -day extension of review for
this permit to allow him time to return and address my concerns.
Please consider that idea and let me know by C.O.B. today and I will
prepare such a letter for your files.
Sincerely,
Pamala Myers

5. Directions to Site: From Wilmington, travel on 74/76 and take Leland exit. Take second
light and turn right. Travel to the 90 degree turn in the road. Travel to Royster Road and
make a right. The plant will be near the end of the road on the left.
6. Discharge Point: Cape Fear River (03-06-17).
9. Receiving stream or affected surface waters: Cape Fear River, Class SC,HQW,PNA
a. Classification: "Correction Needed on Permit" SC, PNA, HQW
b. River Basin and Subbasin No.: 03-06-17; AU # 18-(71)a
C. Describe receiving stream features and pertinent downstream uses: Public uses
include fishing, boating and crabbing. There are 41 individual NPDES
wastewater discharges with a total permitted flow of 99.9 MGD to this segment
(49 square miles) of the Cape Fear River with the largest being International
Paper (50 MGD, Progress Energy (3.5 MGD), Northside WWTP (16 MGD),
and Southside WWTP (12 MGD).
d. Aquatic Life Rating: IMPAIRED. There are six aquatic life assessment
stations in this segment and all have exceeded the criteria. Each have exceeded
low DO and low pH. The stressors for this segment are turbidity, low pH,
copper, and low DO.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of wastewater to be permitted: 1.65, 2.475 MGD in Phase I and 3.8 MGD
in Phase Il.
b. What is the current permitted flow limit? 1.65 MGD
C. Actual treatment capacity of the current facility? 1.65 with both trains operating.
This facility does not meet the rules for duality since one oxidation ditch cannot
sufficiently treat the entire flow to reliably meet the permitted limitations. No
calculations can be found in the region that indicates whether the other treatment
processes are capable of treating the entire flow in just one train (clarifier and UV
unit). The operator indicated that one train of filters can sufficiently meet TSS
limitations in the current permit for the entire permitted flow. Coastal Waste
Treatment Disposal rules (15A NCAC 2H.0400) requires all essential treatment and
disposal units shall be provided in duplicate. DWQ reviews for future construction
must ensure duality criteria is met.
d. Date(s) and construction activities allowed by previous Authorizations to Construct
issued in the previous two years: N/A
e. Please provide a description of existing or substantially constructed wastewater
treatment facilities: This plant has BNR capabilities. Existing facilities consist of:
450 KW generator that runs entire facility (with the exception of the maintenance
shop); mechanical and manual bar screen; mechanical grit removal; influent flow
meter; dual anaerobic selector tanks and dual oxidation ditch with mechanical rotors
(2 per reactor); rotary drum thickener with polymer injection system; dual
secondary clarifiers; dual tertiary drum filters; dual UV disinfection units (in series);
parshall flume for flow monitoring; cascade post aeration; aerated sludge holding
(375K gal) tank; and ATAD (50K gal). This plant has no by pass capabilities to any
of the treatment units.
f. Please provide a description of proposed wastewater treatment facilities:
Phase I proposal includes new influent screen, equalization pump station and tank,
oxidation ditch, clarifier, effluent filter, UV disinfection, effluent pump, sludge
thickener, residuals treatment and 24 inch effluent line to Cape Fear River. The
plant has recently received approval (August 16, 2011) for the EA for expansion.
g. Possible toxic impacts to surface waters: Potential for pass through from Industrial
users. NEB manages a pretreatment program for their SIUs. American Distillation
has recently caused an upset by dumping wastewater in exceedance of the SIU
permitted limits.
h. Pretreatment Program (POTWs only): Yes
2. Residuals handling and utilization/disposal scheme: WQ0019702 reuse permit for 0.325
MGD to Magnolia Greens Golf Course is proposed for elimination since the golf course
has implemented its own irrigation system. Land application under WQ0000783 (S&B).
3. The facility has had a good compliance history.
4. "Treatment plant classification: Unchanged (Grade III biological) for 1.65 and 2.475
MGD expansion, however, Grade IV will apply upon completion of the expansion to
3.8 MGD. This permittee is a member of the Lower Cape Fear River Program. Please
ensure the permittee notifies DWQ, should they become delinquent in paying their
membership dues.
SIC Code(s): Unchanged
PART III - EVALUATION AND RECOMMENDATIONS
PNA, HQW should be added to the classification of the receiving stream for the segment
of the Cape Fear River to which this facility discharges (see attached PNA map). Please
impose the appropriate TSS limitations since the facility is capable of meeting the lower
limit (10 mg/L) and they are required to meet lower limits for the reuse permit. 15A
NCAC 9213.0224 (HQW), requires that new or expanded wastewater discharges shall
meet effluent limitation for DO of 6 mg/L. The draft permit indicates 5 mg/L, which
applies only to SC, not HQW. Please correct this to 6 mg/L for all permit limit pages.
The lower Cape Fear River in the vicinity of lock and dam 1 has experienced blue-green
algae blooms every summer now for the past several years. Progress Energy's cooling
lake intake is near the vicinity of the NEB outfall. Progress Energy has identified the
Cape Fear River as the source for their algae bloom issues in Sutton Lake. It would be
prudent to include an opener clause in NEB's permit to allow for nutrient limits should
the algae blooms pose problems for water quality standards further south in the Cape Fear
river.
The appropriate monitoring frequencies associated with a Grade IV facility have been
imposed in the draft permit for the 3.8 MGD expansion. DWQ needs a mechanism to
ensure the Wastewater Certification Unit is notified concerning the change from a Grade
III to Grade IV facility upon completion of the 3.8 MGD expansion. DWQ does not have
a mechanism (currently) to know whether the members of the LCFRP are paying their
yearly dues as required by the MOA.
DWQ could support CG&L in their efforts to ensure that any facility that receives state
grants or loans, who have proposed reuse as part of their disposal, are held to a detailed
compliance schedule defined in their NPDES permits. The compliance schedules could
include the requirement to secure any legal contracts necessary to ensure the POTW and
their partners follow through with the implementation of reuse.
The region is in support of renewal provided the permit is issued with consideration
to the concerns provided herein, is issued in accordance with the Cape Fear River
Basinwide Plan, and no adverse public comments are received concerning this
renew . Thank you for the opportunity to comment.

Fact Sheet
Rmwal -- NPDES Permit NCO086819
Pane I
• The proposed phased expansion will include addition of influent screen, equalization tank,
aeration basins, clarifiers, effluent filters, UV disinfection, and a 24 -inch effluent discharge line.
• The County is expected to construct and operate reclaimed water facilities at the WWTP site.
There has been no development of the re -use portion at this time. However, the planned WWTP
expansion will be designed to comply with reclaimed water effluent standards at 15A NCAC
2T.0906.
RECEIVING STREAM:
• The facility discharges treated wastewater via Outfall 001 to the lower Cape Fear River in the
Cape Fear River Basin (subbasin 03-06-17, RUC 03030005)).
• At the outfall location, the receiving stream is classified SC waters (stream segment 18-(71),
which extends from the upstream mouth of Toomer's Creek to a line across the river from Snows
Point (through Snows Marsh) to Federal Point). The stream segment also falls within Primary
Nursery Area (PNA) waters designated by the Division of Marine Fisheries (DMF), and all PNA
waters are also deemed High Quality Water (HQW).
• The lower Cape Fear River is listed as impaired on the 2010 303(d) list for copper, low dissolved
oxygen, low pH, and turbidity within this stream segment. Much of the low DO condition in the
lower Cape Fear River has been attributed to swamp water inputs.
• The Permittee is a member of the Lower Cape Fear River Program (LCFRP), which conducts
water quality monitoring within the basin to gain a broad water quality perspective. Instream
monitoring requirements as part of an NPDES permit are waived as long as the facility maintains
membership within the LCFRP. The MOA between DWQ and LCFRP was renewed 7/1/2011.
• There is a LCFRP station (B9050025) located within this stream segment. Data for 2006-2010
confirms the low DO condition.
FACILITY PERFORMANCE/COMPLIANCE REVIEW:
• DMR Data. In 2010, effluent monthly averages ranged as follows: flow (1.0-1.5 MGD), BOD
(2-3 mg/1), N113 -N (0.3-1.1 mg/1), TSS (1-2 mg/1), enterococci (1-63 /100ml). The DO Minimum
ranged from 6.5-8.5 mg/l.
• Permit Violations. Compliance over last permit round has generally been good. Some ammonia
violations in Oct/Nov 2008 and Feb/Mar 2009. Facility paid civil penalties totaling $5,130
during this period.
• Aquatic Toxicity Testing. The facility has passed all quarterly fathead minnow 24-hour acute
toxicity tests (n= 18) at 90% effluent, for period 1/2007 through April 2011. The acute test
reflects the tidal nature of the receiving stream.
• Compliance Inspections. The facility received "Compliant" ratings for the last Compliance
Evaluation Inspection (CEI) conducted 5/12/2010, as well as the last Pretreatment Compliance
Inspection (PCI) conducted 8/27/2009.
• Compliance Conclusion. There are no significant areas of non-compliance noted over the past
permit round.
PERMIT LIMIT DEVELOPMENT (Existing Conditions- 1.65 MGD
• Maintain limits for BOD and NH3-N at 5&1 mg/1 respectively during summer per Cape Fear
Basin Plan.
• TSS: Incorporate more stringent TSS limits of 10 mg/l (Monthly Average) and 15 mg/1 (Weekly
Average) based on the Primary Nursery Area (PNA) designation, which is subject to more
stringent High Quality Water requirements outlined in 15A NCAC 2B.0224. This facility added
effluent filters to treat to reuse standards during the last expansion, therefore complying with the
more stringent TSS limits should be immediate.
• Remove TRC limit/monitoring, since facility utilizes UV disinfection.
• Add Weekly Average Enterococci limit of 276/100 ml (geometric mean) based on Federal
criteria. Monthly Average limit already exists.

• Maintain pH limits at 6-9 s.u. range. The historical basis for using the freshwater pH range
rather than saltwater pH range is to reflect the normal pH conditions of the receiving water. The
waters immediately upstream of the discharge are classified C Swamp, and upstream pH values
are typically lower due to swamp impact. The pH limit is still consistent with the narrative part
of the standard which specifies that the pH should be normal to the waters of the area.
• Change Effluent DO limit from 5 mg/1 to 6 mg/l, to reflect HQW requirements per 15A NCAC
2B.0224.
• Reasonable Potential Analysis (RPA) for Toxicants: An RPA was conducted to determine need
for metals limits. The RPA assumed no dilution due to tidal influence. There was RP for copper
and zinc, which are Action Level parameters. Per AL policy, add quarterly monitoring in
conjunction with toxicity test. As long as facility is passing toxicity tests, there is no need for
permit limits. The receiving stream is also listed as impaired for copper.
• Add quarterly mercury effluent monitoring and specify low level mercury analysis (EPA Method
1631 E) to support future mercury TMDL implementation. Historical mercury data was analyzed
via Method 245. 1, which only measures down to 200 ng/1.
• The current permit is a conjunctive use permit providing for effluent reuse to Magnolia Greens
Golf Course. However, the golf course eventually developed their own irrigation water supply
and no longer expresses interest in reuse water. Therefore remove permit language on
Supplement to Permit Cover Page regarding reuse at golf course. The facility is still expected to
pursue reuse options in the future.
PERMIT LIMIT DEVELOPMENT (Proposed Phased Expansion to 2.475 MGD/ 3.8 MGD):
Water Quality Modeling Results. In response to low dissolved oxygen (DO) concerns in the
lower Cape Fear River estuary, the NC DENR funded the development of a three-dimensional
water quality model (Environmental Fluid Dynamics Code, or EFDC) by UNC -Charlotte (Bowen
et al, 2009). This model was used to investigate the effects of various organic loading
reductions; see http://h2o.enr.state.nc.us/tmdl/documents/LCFR DOModelReport Final.pdf.
Overall, the EFDC model indicated that the DO deficit caused by sediment oxygen demand
(SOD) and upstream river/wetland/swamp loadings are the dominant sources of oxygen
demanding wastes to the estuary, as opposed to WWTP loadings. A modeling scenario was
specifically conducted for the proposed expansion at Northeast Brunswick Regional WWTP
(looking at permitted flows of 1.65 MGD, 4.65 MGD, and 15 MGD, and at BOD/NH3-N
concentrations of 5/1 mg/1). Despite the large range in assumed wastewater flows, there were
only very small decreases in the predicted DO concentrations (always less than 0.05 mg/1) for
summertime conditions in the impaired region. The mean model error was less than 0.01 mg/l.
Based on the totality of this model analysis, it appears that the proposed expansion to 3.8 MGD
would have an insignificant impact on instream DO. The Division is currently evaluating its DO
water quality standard relative to natural background conditions for the lower Cape Fear River,
prior to any TMDL development.
SEPA/FONSI Determination. The proposed expansion was subject to review by governmental
agencies under the State of North Carolina Environmental Policy Act (SEPA EA), and DWQ has
concluded that the proposed project will not result in significant impacts to the environment. A
Finding of No Significant Impact (FONSI) was issued on August 16, 2011 and is available for
inspection at the State Clearinghouse.
Antidegradation Review. Per NC Antidegradation Policy (15A NCAC 2B.0201), each applicant
for an NPDES permit expansion must document an effort to consider non -discharge alternatives
pursuant to 15A NCAC 211.0105(c)(2). This alternatives evaluation was submitted as part of the
SEPA EA document, and resubmitted as an Engineering Alternatives Analysis (EAA) for the
permit review and modification. DWQ staff reviewed both the flow justification as well as the
alternatives analysis. DWQ staff concurred with the projected flow needs based on a 20 -year
planning horizon. Rapid growth has occurred in the area between 2000-2009; Leland, Navassa,
and Belville (all in the service area) were three top growth municipalities in NC during this time
period, and Brunswick County also grew rapidly at greater than 46%. The service area
population is projected to increase from 25,102 (in 2010) to 49,877 (in 2030). Likewise, DWQ
concurred with the alternatives analysis conclusion that expansion at the current location with a
Fact Sheet

direct discharge to surface water was the most environmentally sound alternative from the
reasonably cost-effective options (per 15A NCAC 21-1.0105). A cost evaluation for a non -
discharge spray irrigation option for the expanded wastewater volume (2.15 MGD) would require
1,382 acres and a total project cost of $72 Million; in comparison, the total estimated project cost
for expanding the current WWTP with direct discharge was estimated at $43 Million,
representing a 67% cost savings. The area is known to have soil limitations for onsite septic
systems, including presence of a high water table. DWQ concludes that the proposed expansion
will provide for public health benefits and social benefit to the community by providing
necessary regional wastewater treatment services to accommodate future growth.
Proposed Limits/Monitoring.
o BOD/NH3-N: Maintain limits of 5/1 mg/l (summer) based on water quality modeling
results predicting no change to instream DO at these limits.
o TSS: More stringent TSS limits of 10/15 mg/l will be required based on PNA
designation, which is subject to more stringent High Quality Water requirements
outlined in 15A NCAC 2B.0224.
o Dissolved Oxygen (DO): a limit of 6 mg/1 is required based on PNA/HQW requirements
stated in 15A NCAC 213.0224.
o Enterococci bacteria: Maintain Monthly Average limit of 35/100 ml, and incorporate
Weekly Average limit of 276/100 ml.
o Copper/Zinc. Based on RP, quarterly monitoring in conjunction with toxicity testing.
Both parameters are Action Level standards, which do not require permit limits as long
as facility is passing the toxicity test. The receiving waterbody is also listed as impaired
for copper.
o Nutrients: There are no nutrient limits proposed in this permit, since the receiving
waterbody is not listed as NSW and/or 303(d) impaired for chl-a. Nutrient monitoring
will continue.

Pro o ro'ec
TheLhase 1 �epansion will include new influent screen, equalization pump station and
tank, oxi a ion ditch, clarifier, effluent filter, ultraviolet disinfection, effluent pump,
sludge thickener, residuals treatment, and 24-inch effluent into the Cape Fear River.
The land -disturbing activity associated with the project will consist of clearing and
grubbing of vegetation, grading and paving of a new access road, construction of
several impoundments, residuals basin, and structures. Construction will also
incorporate utilities and sediment and erosion control measures such as temporary
sediment traps, silt fence, and gravel construction entrances. The disturbed area for
this construction phase is 5 acres.
The existing impervious areas on the site total approximately 40,075 square feet and the
site was originally permitted under DWQ Permit # SW8 990722. This permit is
considered a low density permit with up to 30% built upon area allowed. This phase of
the project will add built upon area of 31,500 square feet resulting in a proposed built
upon area percentage of 18%.
The existing runoff patterns around the existing buildings and structures roughly north
to south through sheet flow conveyances and swales. Currently there are two swales
that discharge to the roadside ditch along Royster Road. The new access road will have
a swale on each side and will drain toward Royster Road and to an existing drainage
ditch near the rear of the site. The access road will cross the ditch with dual 48" RCP with
headwalls.
The project will be funded by the County and the utilities that contribute flow.

Narrative of process flows and equipment descriptions of the Northeast Brunswick
Regional WWTP (NC0086819)
The Northeast Brunswick Regional WWTP (NC0086819) was constructed and placed
into service in July 2004. Average Daily flow into the Facility for 2010 was 1.34
MGD.The system has complete redundancy in units/ equipment with the exception of the
mechanical bar screen, grit removal, rotary drum thickener and ATAD reactor.
All flow into the facility is routed thru an influent flow meter then the Headwork's, which
consists of a mechanical bar screen and grit removal unit. All flow from these units then
proceeds to the anaerobic selector section of the oxidation ditch structure. Here it is
mixed with the return activated sludge (RAS) before entering the reactor (aerobic
treatment). Level is maintained by a set of mechanical weirs, dissolved oxygen levels
are maintained by mechanical rotors (2 per reactor) and rotor immersion thru the
programmable logic controllers (PLC) to our SCADA system. At the discharge point of
the reactors influent flow is split evenly between our (2) clarifiers. RAS from these 2 units
is approx. 70% of incoming flow to the anaerobic selector section for mixing with the
incoming waste for further treatment.
Waste activated sludge is removed 3 times per week (Approx. 30K gallons per
occurrence) thickened by a rotary drum with polymer injection and then batched into our
ATAD reactor (50,000 gallon) in 5K -gallon increments. After time/temp. parameters have
been met flow is then discharged (5K gallons) to our approx. 375,000 gallon Sludge
Holding tank which is mixed by jet aeration prior to land application.
Clarifier effluent is combined and routed thru our (2) tertiary effluent filters to the
ultraviolet disinfection unit. After disinfection flow is measured in a parshall flume before
entering a cascade aeration chamber and ultimate discharge thru our effluent wet well (3
submersible pumps) and discharge to the Cape Fear River. Our current permit is a
conjunctive use permit allowing up to .325 MGD to be supplied as re -use water. There
has been no development of the re -use portion at this time.
