Land Application of Residuals from the
Treatment of Wastewater
Pitt County
In accordance with your application received on July 25, 2000 as well as the additional information
received on February 23, 2001, we are forwarding herewith Permit No. WQ0003781, dated May 14, 2001, to the
Greenville Utilities Commission for the continued operation of a residuals land application program with the
option to spray irrigate effluent meeting tertiary treatment standards from the Greenville Utilities Commission
Wastewater Treatment Plant.
This permit shall be effective from the date of issuance until January 31, 2005; shall void Permit No.
WQ0003781, issued Tune 13, 1997; and shall be subject to the conditions and limitations as specified therein.
This permit approves the continued operation of the subject residuals land application program for
another three years. This permit is also being modified to decrease the acreage approved for residuals land
application and effluent spray irrigation from 301.54 acres to 274.10 acres and increase the annual dry tonnage
of residuals permitted for land application from 1,500 to a maximum of 1,575. Note, however, that Greenville
Utilities Commission's request to allow the use of a value equivalent to 50 percent of the detection level for
reporting concentrations of metals present in the residuals and calculation of cumulative loading rates on
specific Iand application sites is denied. If any metal is analyzed as being in a concentration that is below the
detection level in the residuals, it shall be reported as such, and the detection level concentration shall be used to
perform the cumulative loading of the specific metal onto the permitted land application sites.
Furthermore, please note that it appears as if this residuals land application program is somewhat Iimited
in terms of land. Specifically, plant available nitrogen (PAN) is being applied to the permitted land application
sites at rates that may be higher than those recommended by an agronomic approach. Therefore, Greenville
Utilities Commission will be completing an agronomic study throughout the duration of this permit cycle in
order to determine the most appropriate PAN application rate to allow for complete assimilation without
contarmivation of surface water and groundwater resources. The results of this study, along with a schedule to
implement any changes to the residuals land application program that may necessary, will be submitted to the
Division of Water Quality (Division) upon permit renewal.

Please take time to review this permit thoroughly. The Division has attempted to prepare this permit so
that it more comprehensively addresses both the residuals land application and the effluent spray irrigation
activities that are part of the overall residuals land application program. Also, the following amended provisions
may be of specific interest to you:
♦ General: The system description for this residuals land application program has been amended to
decrease the approved application area to 274.160 acres of agricultural land in Pitt County. In
addition, the volume of residuals that may be land applied has been increased to a maximum of
1,575 dry tons per year. Note that this permit will expire in three years.
♦ Condition 1.4.: This condition has been amended with a requirement that the Washington Regional
Office be contacted in the event that the subject residuals land application program is not operating
satisfactorily.
♦ Condition II. 4.: This condition has been amended to allow the continuation of a 490-pounds of
PAN per acre per year on the residuals land application sites throughout the duration of this permit
cycle. This condition also requires the completion of the agronomic study as described above.
♦ Condition H. 5.: This new condition specifies that effluent spray irrigation is to be completed only
in order to supplement rainfall during dry periods of the year. In addition, the irrigation rate of
effluent shall be limited so that ponding and/or runoff from the land application sites do not occur.
♦ Condition II. 9.: 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 SG .0202.
♦ Condition II. I L: A provision has been added to this condition that requires that an acceptable
cover crop be established within 30 days following land application of residuals on site without an
active cover crop.
♦ Condition II. 23.: This condition prohibits the harvesting of turf for an one-year following an
application of residuals.
♦ Condition III.4.: Note that language regarding the fact that the Division will consider reducing the
pathogen and vector attraction reduction monitoring requirements stipulated in 40 CFR Part 503
upon submission of two years of monitoring data has been removed from this condition.
♦ Condition M. 5.: This condition now allows the Pernnittee to petition the Division to reduce the
toxicity characteristics leaching procedure (TCLP) monitoring frequency to once per permit cycle.
♦ Condition III. 6.: Note that language regarding the fact that the Division will consider reducing the
pathogen and vector attraction reduction monitoring requirements stipulated in 40 CFR Part 503
upon submission of two years of monitoring data has been removed from this condition.
♦ Condition III. 7.: This is a new condition that contains some guidance regarding the residuals
sampling program.
♦ Condition III. 8.: This condition has been amended to reflect the new mailing address to be used
when submitting all monitoring and reporting information.
♦ Condition III. 9.: Events of non-compliance must now be submitted to the Division in written form
within five days (i.e., reduced from 15 days) of the event's occurrence. Note also that the area code
for the Washington Regional Office has changed from 919 to 252.
2

♦ Condition IV. I.: This condition requires that a new groundwater monitoring well, designated as
MW-10, be constructed adjacent to MW-3 within 90 days of this permit's issuance. The
Groundwater Section is requiring this action Because MW-1, MW-3, and MW-6 have been
constructed such that the well screens are too deep. Well screens that do not bracket the water table
may contribute to altered groundwater sample constituent concentrations (i.e., especially with
constituents that are less dense than water). The installation and monitoring of MW-10 will allow
the Groundwater Section to compare its sampling results with those from MW-3. Note that, if there
is much discrepancy between the sampling results from these two groundwater monitoring wells,
the Groundwater Section may recommend that this permit be administratively amended to include a
requirement to install two additional groundwater monitoring wells (i.e., one adjacent to MW-1 and
the other adjacent to MW-6).
♦ Condition IV. 2. through Condition IV. 5.: The conditions contain specific requirements and details
related to the location, construction, certification, mapping, and initial sampling of MW-10.
♦ Condition IV. 7.: Note that MW-10 must be incorporated into the semi-annual groundwater
sampling program already established for the eight existing groundwater monitoring wells.
♦ Condition IV. 8.: This condition reminds the Permittee that residuals land application activities are
seasonally -limited on Site No. 10 because the seasonal high water table is less than three feet below
the ground surface during some portions of the year. Note that the restricted season has been
changed to include the period between the months of December through March, inclusive (i.e.,
previously November through April, inclusive).
♦ Condition IV. 9.: This condition has been amended to remind the Permittee that the water table
depth may be verified as being three or more feet below the land surface by using the water level
readings in the groundwater wells. This must be completed during the 24-hour period prior to any
residuals land application event.
♦ Condition VI. 3.: 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. 4.: This condition has been amended to reflect all renewed sites approved for land
application of residuals and spray irrigation of effluent. A total of 274.10 acres of agricultural land
in Pitt County are now approved to this residuals land application program. Note also that Site No.
10 may now receive residuals from. April through November, inclusive (i.e., previously May though
October, inclusive).
♦ Condition VI. T.- 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.
♦ Condition VI. 8.: Note that the results of the agronomic study, along with a schedule to implement
any changes to the residuals land application program that may be necessary, must be submitted as
part of the permit renewal application.
Please pay particular attention to the monitoring and reporting requirements contained 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 North Carolina General
Statutes, and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North
Carolina 27699-6714. Unless such demands are made, this permit shall be final and binding.

9. Maximum slope for residuals land application shall be 10 percent for surface application and 18
percent for subsurface applications.
10. When wastewater treatment residuals are applied, the Class A pathogen requirements and site
restrictions in 40 CFR Part 503.32(a) or the Class B pathogen requirements and site restrictions in
40 CFR Part 503.32(b), and one of vector attraction reduction requirements in 40 CFR Part 503.33
shall be met. Additionally, an evaluation shall be performed that demonstrates the residuals' ability
to comply with this requirement. Upon request, a copy of this evaluation, including all test results
and calculations, shall be submitted.
OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities and land application sites shall be properly maintained and operated at all times.
2. A suitable vegetative cover, as listed in Condition H. 4., shall be maintained in accordance with the
crop management plan outlined by the local Extension Office, the Department of Agriculture, the
Natural Resource Conservation Service, or other agronomist and as approved by the Division.
3. An acceptable pH shall be maintained in the soil, residuals, and Iime mixture, greater than 6.0, on
all land application sites to ensure optimum yield for the crops specified in Condition II. 4. The
agronomist shall provide information on the pH best suited for the specified crop and the soil type.
4. The application rate of residuals shall be such that the following plant available nitrogen (PAN)
loading rates are not exceeded on any land application site for the specified crops:

The Penn ittee shall be allowed to apply up to 490 pounds of PAN per acre per year on all land
applications sites that are established with a coastal bermuda grass cover crop that is overseeded
with a winter rye cover crop. This application rate shall be allowed throughout the duration of this
permit cycle as long as both cover crops are harvested. Concurrently, however, the Permittee shall
perform an agronomic study of its residuals land application program. The goal of this study shall
be to determine the appropriateness of this above -specified loading rate and cover crops on the
approved residuals Iand application sites. The study shall make recommendations as to PAN
loadings that will allow complete assimilation of the applied PAN such that contamination of
surface water and groundwater resources is prevented. The results of the study, along with a
schedule to implement changes to the residuals land application that may be necessary, shall be
submitted to the Division with a permit renewal application (i.e., see Condition VI. 8.).
The spray irrigation of effluent shall be completed only in order to supplement rainfall during dry
periods of the year and shall be such that the rate of application does not result in ponding on and/or
runoff from the land application site.

6. No type of wastewater other that effluent meeting tertiary treatment quality standards from the
Greenville Utilities Commission Wastewater Treatment Plant (i.e., NPDES Permit No.
NC0023931) shall be spray irrigated onto any land application site. In addition, effluent that does
not meet the effluent limits specified in the most recent issuance of NPDES Permit No. NCO023931
issued to Greenville Utilities Commission shall not be spray irrigated onto any land application site.

Upon classification of the facility by the Water Pollution Control System Operators Certification
Commission (WPCSOCC), the Permittee shall employ a certified land application/residuals
operator to be in responsible charge (ORC) of the land application program. The operator must
hold a certificate of the type classification assigned to the land application program by the
WPCSOCC. The Permittee must also employ a certified back-up operator of the appropriate type
to comply with the conditions of 15A NCAC 8G .0202.
10. Adequate procedures shall be provided to prevent surface runoff from carrying any disposed or
stored residuals into any surface waters. In addition, adequate measures shall be taken to prevent
runoff from any land application site that is spray irrigated with effluent.

11. Surface -applied residuals shall be plowed or disced within 24 hours after application on lands with
no cover crop established. An acceptable cover crop shall be established within 30 days of the land
application event.
12. For areas that are prone to flooding or within the 100-year flood elevation, residuals shall be applied
only during periods of dry weather. The residuals shall be incorporated into the soil within 24
hours after application.
13. Appropriate measures shall be taken to control public access to the land application sites during
active site use (i.e., applicable during both residuals land application and effluent spray irrigation
events) and for the 12-month period following the last residuals application event. Such controls
may include the posting of signs indicating the activities being conducted at each Iand application
site.
14. Adequate provisions shall be taken to prevent wind erosion and surface runoff from conveying
pollutants from the residuals application area onto adjacent properties or into any surface waters.
15. Residuals shall not be applied during inclement weather or until 24 hours following a rainfall event
of 0.5-inch or greater in 24 hours. Any emergency residuals disposal measures shall first be
approved by the Division. In addition, spray irrigation of effluent shall not be performed during
inclement weather or when the ground is in a condition that will cause runoff.
16. Residuals shall not be applied to any land application site that is flooded, frozen, or snow-covered.
17. Residuals shall not be applied at rates greater than agronomic rates, unless authorized by the
Division.
18. Animals shall not be grazed on any land application site for 30 days after residuals application.
Land application sites that are to be used for grazing shall have fencing that will be used to prevent
access after each application.
19. Food crops, feed crops, and fiber crops that do not come in contact with the residuals shall not be
harvested for 30 days after residuals application.
20. Food crops with harvested parts that touch the residual/soil mixture and are totally above the land
surface (e.g., tobacco, melons, cucumbers, squash, etc.) shall not be harvested for 14 months after
residuals application.
21. Food crops with harvested parts below the surface of the land (i.e., root crops such as potatoes,
carrots, radishes, etc.) shall not be harvested for 20 months after application of residuals when the
residuals remain on the land surface for four months or longer prior to incorporation into the soil.
22. Food crops with harvested parts below the surface of the land shall not be harvested for 38 months
after application of residuals when the residuals remain on the land surface for less than four
months prior to incorporation into the soil.
2'. Turf shall not be harvested for one year after residuals land application.
III. MONITORING AND REPORTING REQUIREMENTS
1. Any monitoring (i.e., including groundwater, surface water, residuals, soil, or plant tissue analyses)
deemed necessary by the Division to ensure protection of the environment shall be established, and
an acceptable sampling and reporting schedule shall be followed.

2. Proper records shall be maintained by the Permittee tracking all application activities. These
records shall include, but are not necessarily limited to, the following information:

After the residuals have been annually monitored for two years, the Permittee may submit a request
to the Division for a permit modification for the reduction of the TCLP frequency. In no case,
however, shall the frequency of TCLP monitoring be less than once per permit cycle.
6. All residuals included in this permit shall be monitored quarterly, from the date of permit issuance,
for compliance with Condition 1. 10. Data to verify pathogen and vector attraction reduction of the
residuals shall be maintained by the Permittee. The required data shall be specific to the
stabilization process utilized, but also shall be sufficient to demonstrate clear compliance with the
Class A pathogen reduction requirements in 40 CFR Part 503.32(a) or the Class B pathogen
reduction requirements and site restrictions in 40 CFR Part 503.32(b) as well as one of vector
attraction reduction requirements in 40 CFR Part 503.33. In addition, the Environmental Protection
Agency (EPA) certification statements concerning compliance with pathogen reduction
requirements, vector attraction reduction requirements, and management practices shall be
completed quarterly by the proper authority or authorities, if more than one is involved (i.e., either
the person who prepares the residuals, the person who derives the material, or the person who
applies the residuals).

7. Laboratory analyses, as required in Condition 111. 4., Condition 111. 5., and Condition III. 6., shall be
performed on the residuals as they are to be land applied. Specifically, the Permittee operates three,
independent aerobic digesters in, parallel. Land application activities are initiated from each
digester as a batch once compliance with the pathogen reduction and vector attraction reduction
requirements are assured. Once these requirements are met, no additional residuals are introduced
to the digester. For this reason, representative samples for the monitoring required by Condition III.
6. (i.e., pathogen reduction and vector attraction reduction compliance) shall be withdrawn from
each batch and analyzed accordingly. If additional residuals are added to the digester, the batch
shall be sampled and analyzed again for pathogen reduction and vector attraction reduction
compliance prior to initiating/continuing land application. It shall be permissible to analyze
representative samples withdrawn from random batches to comply with the monitoring required by
Condition III. 4. and Condition III. 5. (i.e., metals, nutrients/micronutrients, and TCLP).
Three copies of all required monitoring and reporting requirements as specified in Condition III. 1.,
Condition III. 2., Condition III. 3., Condition 111. 4., Condition III, 5., and Condition 111. 6. shall be
submitted annually on or before March 1st of the year following the land application event to the
following address:
NCDENR-DWQ
Water Quality Section
Non -Discharge Compliance/Enforcement Unit
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Noncompliance Notification:
The Permittee shall report by telephone to the Washington Regional Office, telephone number (252)
946-6481, as soon as possible, but in no case more than 24 hours or on the next working day
following the occurrence or first knowledge of the occurrence of any of the following:
a. Any occurrence with the residuals land application program that results in the land application
and/or spray irrigation of significant amounts of wastes which are abnormal in quantity or
characteristic.
b: Any failure of the residuals land application program resulting in a release of material to
receiving waters.
c. Any time that self -monitoring information indicates that the residuals land application program
and facilities have gone out of compliance with the conditions and limitations of this permit or
the parameters on which they were designed.

IV. GROUNDWATER REQUIREMENTS
Within 90 days of this permit's issuance, an additional groundwater monitoring well, adjacent to
MW-3 and designated as MW-10 shall be installed to monitor groundwater quality. The well shall
be constructed such that the water level in the well is never above or below the screened (i.e., open)
portion of the well at any time during the year. The general location and name for this well is
marked on Figure 1 of this permit. The groundwater monitoring well shall be constructed in
accordance with this permit and approved by the Groundwater Section of the Washington Regional
Office.
2. 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.
3. The Washington Regional Office, telephone number [phone], 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.
4. Within 30 days of completion of all well construction activities, a certification shall be received
from a North Carolina -licensed Professional Engineer or North Carolina -licensed Professional
Geologist certifying that the groundwater monitoring 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 GW-1 Form (i.e., "Well Completion Form") for
each well. Mail this certification and the associated GW-1 Forms to NCDENR-DWQ, Groundwater
Section, Permits and Compliance Unit, 1636 Mail Service Center, Raleigh, NC 27699-1636.
Within 60 days of groundwater monitoring well installation, the 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 Land Surveyor and contains all of the following information_
a. Location of all property boundaries,
b. Location of the waste disposal system,
c. Location of the review and compliance boundaries,
d. Location and identity of each groundwater monitoring well,
e. Location of all supply wells within the property boundaries and within a 500-foot radius of the

g. Relative elevation of the top of the casing for each groundwater monitoring well (i.e,, known as
the measuring point"), and
h. Depth of water below the measuring point at the time the measuring point is established.
9

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.
6. For the initial sampling of the groundwater monitoring well as specified elsewhere in this permit,
the Permittee shall submit a copy of the GW-1 Form with the GW-59 Form (i.e., "Compliance
Monitoring Form") for that well. GW-59 Forms for groundwater monitoring wells that have not
had a GW-I 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
actions pursuant to North Carolina General Statute § 143-215.6.
7. The nine existing groundwater monitoring wells, MW-1, MW-3, MW4, MW-5, MW-6, MW-7,
MW-8, and MW-9, as well as the new groundwater monitoring well, MW-10, shall be sampled
every June and December for the following parameters:
Chlorides Total Ammonia
Copper Total Dissolved Solids
pH Total Organic Carbon
Fecal Coliform Water Level
Nitrate -Nitrogen Zinc
Volatile Organic Compounds (VOCs) in December only, 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 µg/L or less),
(C) EPA Method 8021 (Low Concentration, PQL at 0.5 µg/L or less),
(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 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.
10

If any VOCs are detected by the methods listed, then the Washington Regional Office Groundwater
Supervisor, telephone number [phone], 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 total organic carbon 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 total organic carbon concentration. If the total organic
carbon concentration as measured in the background groundwater monitoring well exceeds 10
milligrams per liter, the concentration shall be taken to represent the naturally -occurring total
organic carbon concentration. Any exceedances of this naturally -occurring total organic carbon
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 on or before the last
working day of the month following the sampling month at the following address:

8. Site No. 10 is dominated by soils having a mean seasonal high water table at 2.5 feet below the land
surface. Therefore, the application of residuals on this land application site shall be prohibited from
December through March, inclusive. Residuals land application may be performed throughout the
remainder of the year (i.e., April through November, inclusive) provided that the three-foot
separation condition described in Condition IV. 9. is met. All other land application sites listed in
Condition VI. 4. are dominated by soils with a mean seasonal high water table that is greater than
three feet below the land surface and are, therefore, approved for year-round residuals land
application.
No residuals shall be applied to any land application site when the vertical separation between the
depth of residuals application and the water table is less than three feet. Verification of the water
table elevation can be confirmed by water level readings obtained from the groundwater monitoring
wells near the site, within 24 hours prior to the Iand application event.
10. The COMPLIANCE BOUNDARY for disposal systems shall be specified by regulations in 15A
NCAC 2L (i.e., Groundwater Classifications and Standards). The Compliance Boundary for
residuals land application programs initiated after December 31, 1983 shall be established at either
(1) 250 feet from the land application area, or (2) 50 feet within the property boundary, whichever is
closest to the land application 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 land
application area midway between the Compliance Boundary and the perimeter of the land
application area. Any exceedance of standards at the Review Boundary shall require remediation
action on the part of the Permittee.
11. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
