Subject: Permit No. WQ0004332
Town of Edenton
Wastewater Spray Irrigation System
Chowan County
In accordance with your minor modification request received June 14, 2000, we are forwarding
herewith Permit No. WQ0004332, dated February 2, 2001, to the Town of Edenton for the continued operation
of the subject wastewater treatment and spray irrigation facilities.
This permit shall be effective from the date of issuance until May 31, 2005; shall void Permit No.
WQ0004332, issued June 1, 2000; and shall be subject to the conditions and limitations as specified therein.
Your correspondence requested that some minor clarifications be made to the permit that was renewed
on June 1, 2000. Most of your requests have been accommodated by this permit issuance. However, please
note that the Division of Water Quality (Division) has maintained the annual average daily flow of 1.076
million gallons per day as the limit for these wastewater treatment and spray irrigation facilities in lieu of using
the 1.096-million gallon per day 30-day average daily flow as was requested in your correspondence. All non -
discharge facilities are permitted and monitored on the basis of the annual average daily flow. As a
clarification to your concern, the Water Quality Section of the Division's Washington Regional Office has
verified that the notice of violation (NOV) issued to the Town of Edenton on May 17, 2000 was not for
violating monthly flow, rather that the daily flow was violated a number of times during the months of
January, September, October, and November of 1999 and again during the months of February and April of
2000. The NOV did utilize the terra, "monthly average flow violations;" however, the intent of this language
was to refer to those months in which the flow violations had occurred. In response to the other clarifications
requested in your correspondence, please note the following amendments that have been made to the language
of this permit:
♦ General: The system description has been amended to refer to the fact that the subject wastewater
treatment and spray irrigation facilities serve not only the Town of Edenton but also its wastewater
customers.
♦ Condition I- 5.: Language has been added to this condition to exempt Division -approved
groundwater monitoring wells from the buffer requirements applicable to wells. Standard permit
language regarding the applicability of buffers to existing wastewater treatment and spray
irrigation facilities, which was accidentally omitted from the June 1, 2000 issuance of this permit,
has also been added to this condition.

♦ Condition 11. 8.: In order to reflect the fact that the wastewater treatment and spray irrigation
facilities permitted herein accept wastewater from generators other than those located in the Town
of Edenton more accurately, this condition has been amended to provide that only effluent from
the Town of Edenton's wastewater treatment facilities may be applied onto the spray irrigation
facilities.
♦ Condition IV. 2.: This is a new condition that is required in all permits issued to non -discharge
wastewater treatment and disposal systems in the State of North Carolina. Specifically, this
condition details the requirements for complying with the influent flow measuring policy adopted
by the Division on May 31, 2000. Note that daily influent flow volumes must now be reported on
Form NDMR-I such that this form must now be submitted on a monthly basis.
♦ Condition V. I.: This condition is being retained in this permit, per a request from the Division's
Groundwater Section. Typically, this condition is included in permits only when new
groundwater monitoring wells are installed. However, the Division's Groundwater Section does
not currently have a map that conforms to the criteria described in this condition for its use.
Because of exceedances of the groundwater quality standards at two of six groundwater
monitoring wells, the Division's Groundwater Section believes that the availability of this map
will allow a better assessment of the wastewater treatment and spray irrigation facilities'
compliance status. Note, however, that you now have a 180-day period with which to comply
with the requirements contained in this condition.
♦ Condition V. 2.: Note that the groundwater monitoring wells must now be sampled for ammonia -
nitrogen instead of the total ammonia parameter previously required. This recommendation made
by the Division's Groundwater Section was accidentally omitted from renewed permit that was
issued on June 1, 2000.
♦ Condition VII. 9. (from June 1, 2000 permit issuance): This condition has been omitted from this
permit issuance because, as your correspondence correctly asserted, it is not applicable to a
publicly -owned treatment works such as the one permitted herein.
As always, please pay particular attention to the monitoring requirements in this permit. Failure to
establish an adequate system for collecting and maintaining the required operational information will result in
future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right
to request an adjudicatory hearing upon written request within 30 days following receipt of this permit. 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, NC 27699-
6714. Unless such demands are made, this permit shall be final and binding.
If you need additional information concerning this matter, please contact Ms. Shannon Mohr
Thornburg at (919) 733-5083, extension 353. ;T

is intended to serve the Town of Edenton and its wastewater customers with no discharge of wastes to surface
waters, pursuant to the application received .tune 14, 2000, and in conformity with the project plan, specifications,
and other supporting data subsequently filed and approved by the Department of Environment and Natural
Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until May 31, 2005; shall void Permit No.
WQ0004332, issued June 1, 2000; and shall be subject to the following specified conditions and limitations:
I. PERFORMANCE STANDARDS
1. The wastewater treatment and spray irrigation facilities shall be effectively maintained and operated
at all times so that there is no discharge to the surface waters nor any contamination of groundwater
that will render them unsatisfactory for normal use. In the event that these facilities fail to perform
satisfactorily, including the creation of nuisance conditions or failure of the irrigation areas to
assimilate the wastewater adequately, the Permittee shall take immediate corrective actions including
those actions that may be required by the Division of Water Quality (Division), such as the
construction of additional or replacement wastewater treatment and disposal facilities.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
waters or groundwater resulting from the operation of the wastewater treatment and spray irrigation
facilities.
The residuals generated from the wastewater treatment facility shall be disposed in accordance with
North Carolina General Statute § 143-215.1 and in a manner approved by the Division.
4. Diversion or bypassing of the untreated wastewater from the wastewater treatment and/or spray
irrigation facilities shall be prohibited.
5. The following buffers shall be maintained by the wastewater treatment and spray irrigation facilities:
a. 400 feet between the wetted area and any residence or place of public assembly under separate
ownership,
b. 150 feet between the wetted area and any property line,
c. 100 feet between the wetted area and any well (i.e., with the exception of an approved
groundwater monitoring well),
d. 100 feet between the wetted area and any drainageway or surface water body,
e. 50 feet between the wetted area and any public right-of-way,
f. 100 feet between wastewater treatment units and any well (i.e., with the exception of an approved
groundwater monitoring well), and
g. 50 feet between wastewater treatment units and any property line.
Some of the buffers specified above may not have been included in previous permits for the
wastewater treatment and spray irrigation facilities. The Permittee does not have to modify
previously -approved facilities to comply with these buffers unless specifically required by the
Division to do so, nor are these buffers intended to prohibit or prevent modifications that may be
required by the Division to improve the performance of the existing facilities. These buffers do,
however, apply to modifications of the system that are for the purpose of increasing the wastewater
flow that is tributary to the facilities. These buffers do apply to any expansion or modification of the
facilities and apply in instances in which the sale of property would cause any of the buffers with
which the facilities now comply to be violated. The Permittee shall be advised that any modification
to the existing facilities will require a permit modification.
II. OPERATION AND MAINTENANCE REQUIREMENTS

will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the wetted area of the spray
irrigation facilities.
6. The wastewater treatment and spray irrigation facilities shall be effectively maintained and operated
as a non -discharge system to prevent the discharge of any wastewater resulting from the operation of
these facilities.
7. The application rate onto the spray irrigation areas shall not exceed a cumulative loading of 46.8
inches over any 12-month period at an instantaneous application rate not to exceed 0.25 inches per
hour.
8. No type of wastewater other than effluent from the Town of Edenton's Wastewater Treatment
Facility shall be sprayed onto the wetted area of the spray irrigation facilities.
9. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while
normal maintenance is being performed.
10. Public access to the wetted area of the spray irrigation facilities shall be controlled during active use.
Such controls may include the posting of signs that describe the activities being conducted at the

f. Depth of water below the measuring point at the time the measuring point is established.
This survey shall be conducted using approved practices as outlines in the North Carolina General
Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56. The surveyor
shall establish a horizontal control monument on the property of the disposal system and determine
the latitude and longitude of this horizontal control monument to a horizontal positional accuracy of
+/-10 feet. All other features listed above shall be surveyed relative to this horizontal control
monument. The positional accuracy of these features shall have a ratio of precision not to exceed an
error of closure of one foot per 10,000 feet of perimeter of the survey. Any features located by the
radial method shall be located from a minimum of two points. Horizontal control monuments shall be
installed in such a manner and made of such materials that the monument will not be destroyed due to
activities that may take place on the property. The map shall also be surveyed using the North
American Datum of 1983 (NAD 83) coordinate system and shall indicate the datum on the map. All
bearings or azimuths shall be based on either the true or NAD 83 grid meridian. If a Global
Positioning System (GPS) is used to determine the latitude and longitude of the horizontal control
monument, a GPS receiver that has the capability to perform differential GPS shall be used and all
data collected by the GPS receiver shall be differentially corrected.
The map and any supporting documentation shall be sent to NCDENR-DWQ, Groundwater Section,
Permits and Compliance Unit, 1636 Mail Service Center, Raleigh, NC 27699-1636.
2. The existing groundwater monitoring wells, MW-1, MW-2, MW-3, MW-4, MW-6, and MW-7 shall
be sampled every April, August, and November for the following parameters:
Ammonia -Nitrogen (NH3-N) pH
Chlorides Total Dissolved Solids (TDS)
Fecal Coliform Total Organic Carbon (TOC)
Nitrate -Nitrogen (NO3-N) Water Level
Volatile Organic Compounds (VOCs) in November only
The analysis for VOCs shall be completed using one of the following methods:
(A) Standard Method 6230D (PQL at 0.5 µg/L or less),
(B) Standard Method 6210D (PQL at 0.5 µglL or less),
(C) EPA Method 8021 (Low Concentration, PQL at 0.5 µglL or Iess),
(D) EPA Method 8260 (Low Concentration, PQL at 0.5 µg/L or less), or
(E) Another method with prior approval by the Groundwater Section Chief.
Any method used shall meet the following qualifications:
(1) The laboratory shall be Division -certified to run any method used.
(2) The method used shall, at a minimum, include all the constituents listed in Table
VIII of Standard Method 6230D.
(3) The method used shall provided a PQL at 0.5 µglL or less, which shall be
supported by laboratory proficiency studies as required by the Division's
Laboratory Certification Unit. Any constituents detected above the MDL, but
below the PQL at 0.5 µglL, shall be qualified (estimated) and reported.
If any VOCs are detected by the methods listed, then the Washington Regional Office Groundwater
Supervisor, telephone number (252) 946-6481, shall be contacted immediately for further instructions
regarding any additional follow-up analyses required. The results of all initial and follow-up analyses
shall be submitted simultaneously.
If TOC concentrations greater than 10 milligrams per liter are detected in any downgradient
monitoring well, additional sampling and analysis shall be conducted to identify the individual
constituents comprising this TOC concentration. If the TOC concentration as measured in the
background groundwater monitoring well exceeds 10 milligrams per liter, the concentration shall be
taken to represent the naturally -occurring TOC concentration. Any exceedances of this naturally -
occurring TOC concentration in the downgradient wells shall be subject to the additional sampling
and analysis as described above.
The measurement of water levels shall be made prior to sampling the groundwater for the remaining
parameters. The depth to water in each monitoring well shall be measured from the surveyed point
on the top of the casing.
The results of the sampling and analysis shall be received on the GW-59 Form (i.e., "Groundwater
Quality Monitoring -Compliance Report Form) on or before the last working day of the month
following the sampling month at the following address:
