Dear Ms. Ipock:

Subject:NPDES Permit Issuance
Permit No. NC0031828
Vanceboro WWTP
Craven County
In accordance with the application for discharge permit received on October 12, 1998,
the Division is forwarding herewith the subject NPDES permit. This permit 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 May 9, 1994 (or as subsequently amended).
The Public Hearing determination was to re -issue the permit as originally drafted. The
following items from the DRAFT permit have been retained in this FINAL permit:
• A decrease in monitoring frequencies for several parameters, which is reflective
of the Grade II classification received under the new facility rating system.
Monitoring frequencies for Grade II facilities are specified in 15A NCAC
2B.0500. Currently, all biological WWTP's with permitted flow < 0.5 MGD are
rated Grade II, unless biological nutrient reduction is employed.
• Deletion of instream monitoring for fecal coliform and conductivity, based on
updated NPDES instream monitoring policy for 100% domestic dischargers.
• Deletion of quarterly effluent monitoring for NO2+NO3, since additional total
nitrogen monitoring will be added.
• Increase total nitrogen effluent monitoring from quarterly to 2/Month, while
total phosphorus effluent monitoring remains at weekly. These changes are
consistent with the nutrient permitting strategy for the Neuse River Basin.
• Change the permit expiration date to 4/30/2003.
This facility's discharge is located in the Neuse River Basin, in which all streams have
been designated as nutrient sensitive waters (NSW) as a result of algal bloom problems
in the estuary. The North Carolina Environmental Management Commission recently
adopted rules establishing the Neuse River Basin Nutrient Sensitive Waters
Management Strategy for the reduction of phosphorus and nitrogen inputs. The point
source rule (15A NCAC 2B .0234) is intended to reduce total nitrogen (TN) discharges

by 30% by 2003. It specifies that individually permitted wastewater discharges to the
Neuse River Basin with permitted flows less than 0.5 MGD in 1995 shall be allocated a
collective annual mass load of 155,400 pounds/year of total nitrogen. This is
equivalent to an allocation in the range of 5 - 10 mg/1 TN for each small discharger.
Although no total nitrogen limits appear in the permit at this time, you may be
subject to nitrogen limits in the next permitting cycle. All facilities with permitted
flow greater than or equal to 0.5 MGD are receiving a TN limit in this permit cycle.
The Division recommends that you evaluate the cost of installation for nutrient
removal facilities in the event that a nutrient limit is imposed on your plant. It is also
recommended that alternative discharge options be evaluated such as spray irrigation,
subsurface systems, wastewater reuse, or connection to a larger regional system.
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. Part II, E.4. addresses the requirements to be followed in
case of change in ownership or control of this discharge. The Division of Water
Quality 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 concerning this permit, please contact Tom Belnick at
telephone number [phone], ext. 543.

A. (3.) TOTAL NITROGEN CALCULATIONS
The Permittee shall calculate the annual mass loading of total nitrogen as the sum of
monthly loadings, according to the following equations:
(1) Monthly Mass Loading (lb/month) = TN x Q x 8.34
where:
TN = the average total nitrogen concentration (mg/L) of the composite
samples collected during the month
Q = the total wastewater flow discharged during the entire month
(MG/month)
8.34 = Conversion factor
(2) Annual Mass Loading (lb/yr) = E (Monthly Mass Loadings) for the calendar
year
The Permittee shall report the total nitrogen concentration for each sample and the
monthly mass loading in the appropriate monthly discharge monitoring report. In
addition, the annual mass loading of total nitrogen shall be reported in the December
discharge monitoring report for the year.

Recommendations
Neuse River Basin Public Hearings
May 4, 2000
Town of Vanceboro
Vanceboro WWTP
NC0031828
Facility Description
The Town operates a wastewater treatment plant in Craven County, with phased flows of 0.25 and 0.30
MGD and discharging to Swift Creek. The treatment consists of manual bar screens, grit removal, parallel
aerated oxidation ditches, secondary clarifiers, tertiary sand filters, alum feed for phosphorus removal,
polymer feed for alum sludge, gas chlorination, dechlorination, cascade post aeration, flow meter, aerobic
sludge digesters, sludge drying beds, and standby power. Outfall pipe was relocated in 1995. The public
hearing focused on flooding, historical problems, and O&M issues.
Permit Summary
Permit has phased flow limits (0.25, 0.30 MGD) and was renewed with same advanced tertiary limits
(BOD/NH3 of 5/2 summer, 10/4 winter) and quarterly TP = 2 mg/1. In 1999, facility was consistently
meeting 5/2 limits and TP limit.
Public Comments
• NRF contends that this WWTP is vulnerable to flooding. Vanceboro reponds that facility is located
3-feet above 100-year floodplain, and that no part of the WWTP was ever flooded until the 1999
hurricanes dropped 40 inches of rain.
• NRF recommends nutrient limits now (Note: facility already has TP limits).
• NRF recommends more investigation/remedial work on collection infrastructure. Vanceboro
responds that they smoke -test and repair lines immediately when problems are noted. Vanceboro also
made repairs to collection system due to excessive I&I in 1994.
DWQ Response and Discussion
• Flooding was an issue during the hurricane (Floyd) but does not appear to be a significant concern at
other times.
• NRF request for nutrient limits would not be consistent with the Neuse Nutrient Management
Strategy. Draft permit includes monitoring only for TN, similar to all other facilities with permitted
flow < 0.5 MGD. This facility already has TP limits. The issue of giving TN limits will be considered
during Phase II of the TMDL development.
Recommended Action(s)
Re -issue the permit as drafted.

Condition of Receiving Waters: Classified as "C-Swamp-Nutrient Sensitive Waters" -
The 98 basinwide plan indicates a continuing decline in water quality in the Swift Creek
watershed where this facility is Iocated. 81 % of these streams do not support their
intended uses (the lowest rating) and the other 19% are only partially supporting (the 2nd
lowest rating).
Comments:
In 1992 this facility was placed under a Special Order of Consent (SOC) by the EMC
because they could not meet their permit limits for flow, BOD and NH3 (ammonia
nitrogen). The received a federally funded grant and low interest loan to upgrade the
sewer treatment plant and a condition of the loan required them to make repairs to the
collection because of excessive inflow & infiltration. These construction projects were
completed in 1994.
The pollutant discharge limits that were raised for this facility during the years that they
operated under this SOC included the same pollutants that are identified as causes of the
impaired water quality in this area.
Despite that, we noted with concern, that again in 1995 they had applied for another SOC
because of continuing flow violations. But the Town chose not to execute this SOC
because they managed to get back into compliance.
Notices of Violation were given to Vanceboro for discharges that violated their permit
limits for BOD in June of 98 and NH3 (ammonia nitrogen) in July of 98.
Finally, the location of this facility in such a vulnerable floodplain must be noted.
Though the recent flooding from Floyd proved an extreme event that flooded many sewer
plants, this facility has had previous flooding as well.

Recommendations:
More investigation and remedial work on the Town's collection infrastructure is
warranted given the continuing problems and the growth in this community that
will continue to increase the flow requirements.
The States continuing failure to get wastewater treatment facilities out of the most
vulnerable floodplain in the Neuse Basin must be addressed. When communities
like Vanceboro get funding for significant capital improvements to the treatment
system more must be done to relocate them.
Though a minor discharger, nutrient limits should to be imposed now. The current
state of water quality impairment due - to excessive nutrients in this particular
watershed - make this need more immediate.

Dear Sir
ALDERMEN:
RICHARD BOWERS
SHIRLEY'BRYAN
ROY BUCK
DAVID FILLINGAME
A. F. WHITLEY
I was quite surprised to learn that the Neuse River Foundation has challenged the renewal of the waste
water permit for the Town of Vanceboro. The state inspectors have always indicated that we have one of
the best run facilities in the state. Mr. William Kent, of the foundation, gave a good assessment of our
operation, but did not give you all of the facts.
In early 1992, I advised our town board that we were approaching the maximum number of gallons of
waste for which we were permitted. The board immediately gave me permission to contact our
engineers, Rivers and Associates, and request that they plan for the en!argement of our plant. What Mr.
Kent did not tell you is that we were almost ready to let the contracts for the expansion before the state
informed us of the situation. We have no problem treating our waste, but we did exceed the gallons by a
minimal number before the plant was finished. The state issued a moratorium, which is understandable.
Our current permit is for 300,000 gallons, although the plant is designed to process about 500,000
gallons. At the time of the expansion to the 500,000 gallon capacity, the out fall line was moved from
Maul Run to Swift Creek.
From time -to -time, when we had large, extended rains, we had a small problem with infiltration. I
understand that most systems have this type of problem under such conditions. When this happens, we
immediately have our lines smoke -tested to determine where the leaks are located and then proceed to
repair them immediately. The Vanceboro plant is manned seven days a week, and all of the employees
who work for the Town of Vanceboro know that their first priority is to correct any sewer problem as soon
as it arises.
There has never been a time in the twenty-one years of the operation of our facility that we have not had
adequate funds to repair any breakdown that may have occurred to the system. It is not our desire to do
anything that will harm our environment or water supply in any way. We have no desire tb fight the state
system for water quality control. Our desire is to work with your agency in ensuring that any problems
are corrected in a reasonable amount of time.
When our waste treatment plant was built, it was elevated three and one-half feet above the 100-year
flood plain. In the weeks prior to and during the landfall of Hurricanes Dennis and Floyd, the Town of
Vanceboro received in excess of forty inches of rain. The floodwaters following Hurricane Floyd rose six
feet above the projected 100-year flood plain. Mr. Kent made the statement that we had problems with
flood waters before Hurricane Floyd; however, this is simply not the case. No part of our waste treatment
plant had ever had flood water stand anywhere near it until the 1999 flood. There are two or three small
places in the city limits where a minimal amount of water stands for short periods of time after extensive
rains, but the area drains quickly.

Thank you for giving us the privilege to answer these complaints. If further information is needed, please
feel free to call on us. We look forward to working with you to ensure that our water facility operates at
the highest level possible. I am very proud of the job performance of the employees of the Town of
Vanceboro. They take their work very seriously and do an outstanding job to make our town a better
place to live.

PROJECT NOTES
Summary
• This is a permit renewal for a 0.25 MGD municipal WWTP. Since last permit, facility has
expanded from 0.10 to 0.25 MGD, and relocated outfall from Mauls Swamp to Swift Creek
(both completed by 6/95). Facility is permitted for expansion to 0.30 MGD, but still needs
ATC for construction of final phase.
• Facility is a MINOR, and a non-member of both the LNBA and Group Compliance Assoc.
There is no pretreatment program.
• Facility discharges to Swift Creek. This segment is 303(d) listed in the Draft 2000 List as
Partially Supporting due to sediment, with potential sources listed as
channelization/agriculture. The segment just upstream of the discharge (from source to
Palmetto Swamp) is also listed as biologically impaired (NS Use Rating), with
channelization/agriculture also listed as potential sources. Per Neuse Basin Plan, low D.O.
and low flow are common characteristics of Swift Creek, and nonpoint source impacts have
a high potential to impact water quality in this subbasin. Primary land use for subbasin
030409 is agriculture.
Permitting Strategv
• Based on new WWTP rating system, facility will be Class II at both 0.25/0.30 MGD flows;
therefore, adjust monitoring frequencies accordingly (Note: facility was previously rated
Class III by old rating system).
• Delete instream fecal conform and conductivity monitoring based on NPDES Instream
Policy.
• Incorporate TN Calculations as Special Condition to permit. Add language re: potential
future TN limits to cover letter.
• Only difference between 0.25 and 0.3 MGD effluent sheets is the change in flow limit.
DMR Data.
• Effluent Data. Reviewed DMRs from 1/99-2/00. Facility was compliant with exception of
one monthly flow violation. Generally, monthly average values ranged from: 0.12-0.26
MGD (flow, versus 0.25 MGD limit); <2-2.3 mg/1 (BOD5); 0.03-0.5 mg/1 (NH3); <1-3 mg/1
(TSS); <1-3 orgs/100 ml (fecals); 8-22 mg/1 (TN); 0.2-1.3 mg/1 (TP). Facility consistently
meeting 5/2 limits, as well as TP limit of 2 mg/1..
• Instream Data. Data for same period shows no decrease in downstream D.O. However,
data indicates that natural background D.O. (upstream sample) is low during summer
period (4-5 mg/1; June -Sept.) due to swamp conditions.
WLA Data.
• Last WLA was conducted in 1993 for the proposed expansion to 0.3 MGD (IWC= 38%).
Modeling results predicted that with advanced tertiary limits of 5/2, the additional flow
would not impact water quality in Swift Creek, and loading of oxygen -consuming waste
would not increase above current loading.
Region Data.
• WaRO conducted site visit in November 1998 and recommends that NPDES permit be
reissued. A CEI was conducted in November 1998, which reported the facility to be in
compliance with its NPDES permit with regards to O&M, monitoring reports, and effluent
quality.

Note: Wetlands Restoration projects. Chavis Park project in Wake County includes analysis of contributing watershed, restoration of the stream and buffers along the stream. Implementation should reduce
sediment in stream, reduce peak flows and reduce nutrients, sediment, and organics from urban runoff. The Kentwood Park project in Raleigh aims to restore degraded, incised urban stream back to stable stream
type. Activities include planting riparian buffer and working with Raleigh Parks to incorporate recreational areas. Implementation should yield reduced sediment from banks and runoff and reduced stormwater
problems due to urban development.
