Harnett County
In accordance with your permit modification application package received on July 21, 1999 as well as
the additional information received on December 17, 1999; July 28, 2000; August 4, 2000; March 12, 2001; and
July 12, 2001, we are forwarding herewith Permit No. WQ0002994, dated August 6, 2001, to the Southwest
Water and Sewer District of Harnett County for the construction and continued operation of the subject
wastewater treatment and spray irrigation facilities.
This permit shall be effective from the date of issuance until August 31, 2004; shall void Permit No.
WQ0002994, issued on September 30, 1999; and shall be subject to the conditions and limitations as specified
therein.
This permit approves the modification of the existing wastewater treatment and spray irrigation facilities
such that they may accommodate up to 700,000 gallons per day of influent wastewater flow. Please tape the
time to review this permit thoroughly as some of the conditions contained therein may have been added or
changed since the Iast issuance of this permit. Of special interest are the following:
♦ System Description: The system description has been amended to allow the continued operation of
the existing wastewater treatment and spray irrigation facilities, abandonment of specific
components of these facilities, as well as the construction and operation of additional facilities.
Note that the system description is not intended to be an all-inclusive list of each component of the
wastewater treatment and spray irrigation facilities, rather the approved plans and specifications
contains detailed information regarding the facilities that the Division of Water Quality (Division)
considers to be approved.
♦ Condition 1. L. This is a new condition that prohibits the initiation of any construction activities
until the appropriate soil and erosion and sedimentation control plan approvals have been applied
for and secured.

♦ Condition I. 2.: Since treatment and disposal will be on -going during the construction period for the
additional wastewater treatment and spray irrigation facilities, this new condition requires that
construction be scheduled and performed in a way such that existing service is not interrupted,
operation of the existing facilities is not jeopardized, and overflows/bypasses/discharges of
wastewater are avoided.
♦ Condition 1. 3.: Because the Division is concerned for the potential of soil erosion during and
immediately following the construction process, this new condition provides some guidance
regarding minimizing land disturbance and maintenance of the existing vegetative cover.
♦ Condition 1. 4.: Because it was not submitted to the Division during review of this permit
modification, a crop management plan must be submitted to and acknowledged before operation of
the additional spray irrigation activities may occur.
♦ Condition 1. 5.: Following construction and prior to operation of any additional wastewater
treatment and spray irrigation facilities, this condition requires that the Division must receive first
receive a document from a North Carolina-Iicensed professional engineer certifying that the
facilities have been installed with the permit, the approved plans and specifications, and other
supporting materials.
♦ Condition I. 6.: This condition requires that the Permittee contact the appropriate regional office to
schedule a pre -operation inspection of the new wastewater treatment and spray irrigation facilities.
♦ Condition II. 2.: This condition has been amended to reflect the adoption of new rules by the Water
Pollution Control System Operators Certification Commission (WPCSOCC). The referenced
regulation is now 15A NCAC 8G .0202.
♦ Condition H. 5.: This condition has been amended to be more general in that any wastewater
effluent from Southwest Water and Sewer District of Harnett County's Carolina Lakes Wastewater
Facilities may now be sprayed onto the wetted area of the spray irrigation facilities.
♦ Condition II. 7.: This condition has been amended to include the approved cumulative and
instantaneous application rates for the new spray irrigation facilities.
♦ Condition II. 8.: This condition has been amended to include information regarding the year-round
vegetative cover to be established on the new spray irrigation facilities.
♦ Condition III. 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. Daily influent flow volumes must now be reported on Form;
NDMR-1 such that this form would be submitted on a monthly basis
♦ Condition III. 5.: It is now Division policy to require a standard soil fertility analysis to be
performed on a representative soil sample taken from the spray irrigation field. Records of these
sampling events and results of the analyses must be kept on file by the Permittee. Note that the
Agronomic Division of the North Carolina Department of Agriculture and Consumer Services
offers free soil testing to all North Carolina residents. See this agency's web site at
www.ncagri.comlagronomi or telephone (919) 733-2655 for more information about these services_
♦ Condition III. 6.: Because of the Division's influent wastewater flow measurement policy, Form
NDMR-1 must now be submitted on a monthly basis.
♦ Condition IV. I.: This is a new condition that requires that the liner system to be installed in the
two new lagoons meet certain specifications in order to be acceptable to the Division.
♦ Condition IV. 2.: This new condition precludes operation of the spray irrigation facilities when the
seasonal high water table is less than three feet below the land surface.
2
♦ Condition IV. 3.: This new condition contains guidance regarding the temporary abandonment of
some of the wells that had been previously installed as part of the Permittee's overall groundwater
monitoring program.
♦ Condition W. 4. through Condition W. 9.: Four new groundwater monitoring wells must be
installed as a condition of this permit modification. These conditions contain specific guidance
regarding new well installation, reporting, and monitoring.
♦ Condition W. 10.: Note that total ammonia -nitrogen must now be monitored (i.e., in lieu of
ammonia -nitrogen) in samples withdrawn from the groundwater monitoring wells.
♦ Condition VI. I. This condition has been amended to reflect the fact that an application fee is no
longer required when making an application to the Division to transfer this permit to a new owner or
to reissue this permit such that it reflects a name change of the Permittee.
♦ Condition VI. 5.: Language has been added to this condition to provide examples of some other
rules and regulations that may affect non -discharge systems like this one.
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 trade, this permit shall be final and binding.
One set of the approved plans and specifications is being forwarded to you. If you need additional
information concerning this matter, please contact Ms. Shannon Mohr Thornburg at (919) 733-5083, extension

limitations:
I. PERFORMANCE STANDARDS
1. Construction of the new wastewater treatment and spray irrigation facilities (i.e., those approved
with this permit modification) shall not proceed until the appropriate soil erosion and sedimentation
control plan approvals have been applied for and secured. The certification from the North
Carolina -licensed professional engineer required in Condition L 5. shall serve as proof of
compliance with this condition.
2. Construction of the new wastewater treatment and spray irrigation facilities (i.e., those approved
with this permit modification) shall be scheduled and performed so as not to interrupt the service
provided by and the proper operation of the existing wastewater treatment and spray irrigation
facilities (i.e., those previously approved under this permit) nor result in an overflow, bypass, or
discharge of wastewater to the surface waters of the State.
3. Installation of the new spray irrigation facilities (i.e_, those approved with this permit modification)
shall be performed such that grading and other land disturbing activity is minimized. The Division
of Water Quality (Division) highly suggests that most of the existing vegetative cover in the
proposed wetted area be maintained until the intended year-round vegetative cover (i.e. see
Condition Il. 8.) is adequately established. Minor grading in areas of existing erosion (i.e., old road
beds, etc.) shall be acceptable; however, these areas shall be incorporated into the surrounding
landscape and seeded to control erosion following such grading.
4. Prior to operation of the new spray irrigation facilities (i.e., those approved with this permit
modification), a crop management plan, prepared in accordance with 15A NCAC 2H
.0205(d)(7)(D), shall be submitted to and acknowledged by the Division. Note that the Division may
choose to incorporate new conditions into or amend existing conditions within this permit at that
time. Mail two copies of the crop management plan to the NCDENR-DWQ, Water Quality Section,
Non -Discharge Permitting Unit, 1617 Mail Service Center, Raleigh, NC 27699-1617.
VA
Upon completion of construction and prior to operation of the new wastewater treatment and spray
irrigation facilities (i.e., those approved with this permit modification), a certification shall be
received from a North Carolina -licensed professional engineer certifying that the facilities have
been installed in accordance with this permit, the approved plans and specifications, and other
supporting materials. if the facilities are to be constructed in phases and partially certified, the
Permitt .e shall retain the responsibil.ity to track further construction a roved under the same permit
and shall provide a final certificate of completion once construction of all of the facilities have been
completed. Mail one copy of any partial and final certifications to the NCDENR-DWQ, Water
Quality Section, Non -Discharge Permitting Unit, 1617 Mail Service Center, Raleigh, NC 27699-
1617.
6. The Division's Fayetteville Regional Office, telephone number (910) 486-1541, shall be notified at
least 48 hours in advance of operation of the new wastewater treatment and spray irrigation facilities
so that an in -place inspection can be made. Such notification to the regional water quality
supervisor shall be made during normal office hours (i.e., from 8:00 a.m. until 5.00 p.m.) on
Monday through Friday, excluding State Holidays.
7. 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, such as the construction of additional
or replacement wastewater treatment and disposal facilities.
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.
9. The residuals generated from the wastewater treatment facilities shall be disposed in accordance
with North Carolina General Statute § 143-215.1 and in a manner approved by the Division.
10. Diversion or bypassing of the untreated wastewater from the wastewater treatment and spray
irrigation facilities shall be prohibited.
11. 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,
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.
H. OPERATION AND MAINTENANCE REQUIREMENTS
1. The wastewater treatment and spray irrigation facilities shall be properly maintained and operated at
all times.
2. Upon classification of the wastewater treatment and spray irrigation facilities by the Water Pollution
Control System Operators Certification Commission (WPCSOCC), the Perrnittee shall employ a

irrigation facilities (i.e., those approved with this permit modification), five of the existing
groundwater monitoring wells (i.e., MW-3, MW-7, MW-8, MW-9, and MW-10) shall have their
wellheads secured in such a way as to prevent accidental damage or access by hand. This access
restriction shall be accomplished by utilizing a padlock that would secure a protective cap to the
well casing or by some other means deemed to be acceptable to the Division's Groundwater
Section.
4. Upon completion of construction and prior to operation of the new wastewater treatment and spray
irrigation facilities (i.e., those approved with this permit modification), four groundwater monitoring
wells, one upgradient and three downgradient, shall be installed to monitor groundwater quality.
The wells shall be constructed such that the water level in the wells are never above or below the
screened (i.e., open) portion of the well at any time during the year. The general location and
nomenclature for the wells shall be as marked in Attachment A attached to this permit. Each well
shall be located at the Review Boundary, constructed in accordance with this permit and as
approved by the Groundwater Section of the Division's Fayetteville Regional Office.
All wells that are constructed for the purpose of groundwater monitoring shall be constructed in
accordance with 15A NCAC 2C .0108 (i.e., "Standards of Construction for Wells Other than Water
Supply") and any other state and local laws and regulations pertaining to well construction.
The Groundwater Section of the Division's Fayetteville Regional Office, telephone number (910)
486-1541, shall be notified at least 48 hours prior to the construction of any groundwater monitoring
well, so that an inspection can be made of the well location. Such notification shall be made to the
Regional Groundwater Supervisor during normal office hours (i.e_, from 8:00 a-m_ until 5:00 p.m.)
on Monday through Friday, excluding State Holidays.
Within 30 days of completion of all groundwater monitoring well construction activities, a
certification shall be received from a North Carolina -licensed professional engineer or North
Carolina -licensed professional geologist certifying that the wells are located and constructed in
accordance with 15A NCAC 2C (i.e., "Well Construction Standards") and this permit. This
certification shall be submitted with one copy of a "Well Completion Form" (i.e., GW-1 Form) for
each well. Mail this certification and the associated GW-1 Forms to the NCDENR-DWQ,
Groundwater Section, Permits and Compliance Unit, 1636 Mail Service Center, Raleigh, NC
27699-1636.
8. For the initial sampling of each groundwater monitoring well as specified elsewhere in this permit,
the Permittee shall submit a copy of the GW-I Form with the "Compliance Monitoring Form" (i.e.,
GW-59 Form) for that well. GW-59 Forms for wells that have not had a GW-1 Form previously
submitted shall be returned to the Permittee without being processed. Failure to submit these forms
as required by this permit may result in the initiation of enforcement activities pursuant to North
Carolina General Statute §143-215.6(a)(1).
9. Within 60 days of completion of all groundwater monitoring well construction activities, he
Permittee shall submit two original copies of a scaled topographic map (i.e., with a scale no greater
than one inch equals 100 feet) that has been signed and sealed by a North Carolina -licensed
professional engineer or a North Carolina -licensed professional land surveyor and contains all of the
following information:
a. Location of all components of the wastewater treatment and spray irrigation facilities,
b. Latitude and longitude of the established horizontal control monument,
c. Location and identity of each groundwater monitoring well,
d. Relative elevation of the top of the casing for each groundwater monitoring well (i.e., known as
the measuring point"),
e. Depth of water below the measuring point at the time the measuring point is established,
f. Location of all property boundaries, and
g. Location of the Review and Compliance Boundaries.
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 the NCDENR-DWQ, Groundwater
Section, Permits and Compliance Unit, 1636 Mail Service Center, Raleigh, NC 27699-1636.
10. The four new groundwater monitoring wells (i.e., MW-16, MW-17, MW-18, and MW-19) and the
five existing groundwater monitoring wells (i.e., MW-1, MW-2, MW-4, MW-5, and MW-6) shall
be sampled initially after construction and prior to any disposal activities as well as every February,
June, and September thereafter for the following parameters:
Chlorides Total Ammonia -Nitrogen (NH3-N)
Fecal Coliform Total Dissolved Solids (TDS)
Nitrate -Nitrogen (NO3-N) Total Organic Carbon (TOC)
pH Water Level
Volatile Organic Compounds (VOCs) in September only, using one of the following methods:
(A) Standard Method 6230D (PQL at 0.5 µg/L or Iess),
(B) Standard Method 6210D (PQL at 0.5 µg/L or less),
(C) EPA Method 8021 (Low Concentration, PQL at 0.5 µg/L 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 VII1 of Standard Method 6230D.
(2) The method used shall provide a PQL at 0.5 µg/L 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 µg/L, shall be qualified (estimated) and reported.
If any VOCs are detected by the methods listed, then the Fayetteville Regional Office
Groundwater Supervisor, telephone number (910) 486-1541, 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
groundwater monitoring well, additional groundwater sampling and analysis shall be conducted
to identify the individual constituents comprising the TOC concentration. If the TOC
concentration in the background (i.e., upgradient) groundwater monitoring well exceeds 10
milligrams per liter, this concentration shall be taken to represent the naturally -occurring TOC
concentration in the groundwater. Any exceedance of this naturally -occurring TOC
concentration in downgradient wells shall be subject to additional groundwater 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 groundwater 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 "Groundwater Quality
Monitoring: Compliance Report Form" (i.e., GW-59 Form) on or before the last working day of
the month following the sampling month at the following address:
NCDENR-DWQ

11. The COMPLIANCE BOUNDARY for the disposal system shall be as specified by regulations in
15A NCAC 2L (i.e., "Groundwater Classifications and Standards"). The Compliance Boundary for
a disposal system individually permitted after December 31, 1983 shall be established at either (1)
250 feet from the waste disposal area or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. An exceedance of groundwater quality standards at or beyond the
Compliance Boundary shall be subject to immediate remediation action in addition to the penalty
provisions applicable under North Carolina General Statute §143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY shall be established around the
disposal system midway between the Compliance Boundary and the perimeter of the waste disposal
area. Any exceedance of groundwater quality standards at the Review Boundary shall require
remediation action on the part of the Permittee.
