GUC Residuals Land Application Program (D)
Land Application of Residual Solids (503)
Pitt County
Dear Mr. Elks:
In accordance with your permit modification application package received on July 30, 2002 as
well as the additional 'information received on October 30, 2002, we are forwarding herewith a modified
Permit No. WQ0003781, dated January 3, 2003, to Greenville Utilities Commission for the subject
residuals land application program.
This permit shall be effective from the date of issuance until January 31, 2005; shall void Permit
No. WQ0003781, issued on May 14, 2001; and shall be subject to the conditions and limitations as
specified therein_ Make note of this permit's expiration date and the fact that a permit renewal
application is due to the Division of Water Quality (Division) no later than six months prior to that date
(i.e., see Condition VI. 7.), as the Division does not send reminders to apply for permit renewal.
This permit is being issued to eliminate the requirement to complete an agronomic study to
determine the most appropriate plant available nitrogen (PAN) loading rate to allow for complete
assimilation of the nutrients present in the land applied residuals such that surface water and groundwater
resources were adequately protected. The performance of this agronomic study was negotiated between
the Division and the Permittee prior to the Iast issuance of this permit so that the Permittee could continue
to utilize a PAN loading rate that the Division believed to be greater than agronomically justifiable. The
agronomic study was required to be completed during a shortened permit cycle and then submitted to the
Division for review with a schedule to implement any changes to the residuals land application program
that would be necessary as part of the overall permit renewal application package.
Since the previous issuance of this permit, the Permittee reports that it has been apparent that the
agronomic study's design and implementation would result in "unrepresentative and inaccurate"
determination of the most appropriate PAN loading rate. As such, the Permittee wished to terminate the
study and seek out additional land application sites to supplement the sites that are currently permitted to
the residuals Iand application program. Note that Condition 1.2. of this permit requires that the Permittee
complete this process within 18 months of this permit's issuance.

As always, remember to take the time to review this permit thoroughly, as some of the
conditions contained therein may have been added, changed, or deleted since the last issuance. Pay
particular attention to the monitoring requirements in this permit. Failure to establish an adequate system
for collecting, maintaining, and reporting the required operational information will result in future
compliance problems. Note that the Division has significantly clarified how the Permittee should collect,
maintain, and submit information regarding any wastewater effluent that may be irrigated on the
permitted land application sites in order to supplement rainfall. Since such irrigation did occur during the
2001 calendar year, Condition I. 1. requires that the Permittee prepare and submit an amended annual
report with 90 calendar days of this permit's issuance.
If any parts, requirements, and/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 shall be in the from of a written petition, conforming to Chapter 150B of the North
Carolina General Statutes and fled with the Office of Administrative Hearings at 6714 Mail Service
Center, Raleigh, North Carolina 27699-6714. Unless such demands are made, this permit shall be final
and binding.
If you need any additional information concerning this matter, please contact Ms. Shannon Mohr
Thornburg by telephone at [phone], extension 353, or via e-mail at
[e-mail].

11_ Prior to land applying residuals or irrigating wastewater effluent to any land application site
that has previously received or is intended to receive animal waste (e.g., poultry litter, etc.) or
other source of nutrients (e.g., fertilizer, etc.) in the future, the Permittee shall obtain
information pertaining to the volume and analysis of the applied waste/nutrients from the
landowner and/or lessee/operator of the site. The Permittee shall be responsible for verifying
the volume of residuals that may be land applied or wastewater effluent that may be irrigated
to the site such that the plant available nitrogen (PAN) loading rate for the specified crop (i.e.,
see Condition 11. 13.) shall not be exceeded by all of the sources of PAN applied. Should the
maximum PAN loading rate be met or exceeded, then no additional residuals or wastewater
effluent shall be land applied or irrigated to the site.
12. A suitable vegetative cover, as listed in Condition II. 13., shall be maintained on Iand
application sites onto which residuals are land applied and wastewater effluent is irrigated in
accordance with the crop management plan outlined by the local Cooperative Extension
Office, the Department of Agriculture and Consumer Services, the Natural Resource

applied or stored residuals as well as any irrigated or stored wastewater effluent into any
surface waters.
24. Surface -applied residuals shall be plowed or disced within 24 hours after land application on
land application sites with no cover crop established.
25. For land application sites that are prone to flooding or within the 100-year flood elevation,
residuals shall be land applied and wastewater effluent shall be irrigated only during periods
of dry weather. The residuals shall be incorporated into the soil within 24 hours after land
application.
26. Residuals shall not be land applied during inclement weather or until 24 hours following a
rainfall event of 0.5-inch or greater in 24 hours. In addition, wastewater effluent irrigation
shall not be performed during inclement weather or when the ground is in a condition that will
cause runoff. Any emergency residuals Iand application or wastewater effluent irrigation
measures shall first be approved in writing by the Division.
2T Residuals shall not be land applied nor shall wastewater effluent be irrigated to any land
application site that is flooded, frozen, or snow-covered.
28. Appropriate measures shall be taken to control public access to the land application sites
during active site use and for the 12-month period following the last residuals land application
or wastewater effluent irrigation event, Such controls may include the posting of signs

reduce the frequency of this monitoring requirement. In no case, however, shall the frequency
of this monitoring be less than once per year when a residuals land application event of
residuals generated by the residuals source -generating facility occurs during that year.
4. An analysis shall be conducted on wastewater effluent generated by each residuals source -
generating facility listed in the most recently -certified Attachment A of this permit.. The
analysis shall be performed once a month during those months in which a wastewater effluent
irrigation event takes place. Note that it shall be acceptable to the Division for the Permittee
to submit results of analyses for identical parameters monitored to comply with NPDES
Permit No. NCO023931. Results shall be reported on Form NDMR-L 1, which shall only be
required for those months in which a wastewater irrigation event takes place. All results shall

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). Only residuals
that are generated by the residuals source -generating facilities that are identified as being
exempt from Condition 1. 9. in the most recently -certified Attachment A of this permit shall
not be required to comply with this monitoring requirement.
6. Laboratory analyses as required by Condition III. 2., Condition III. 3., Condition III. 4., and
Condition III. 5. shall be.performed/gathered on the residuals as they are to be Iand applied
and on the wastewater effluent as it is to be irrigated. Furthermore, analytical determinations
made pursuant to the monitoring and reporting requirements of this permit shall be made by a
laboratory certified by the Division for the required parameters) under 15A NCAC 2H .0800
or 15A NCAC 2H .1100.
Proper records shall be maintained by the Pem- ittee tracking all residuals land application and

Volatile Organic Compounds
(in December only)
Copper
Total Ammonia
Fecal Coliform
Total Dissolved Solids
Water Level
Nitrate -Nitrogen
Total Organic Carbon
Zinc
13

Water levels in the groundwater monitoring wells shall be measured prior to sampling the
groundwater for the remaining parameters. The depth to water in each well shall be
measured from the surveyed point on the top of the casing, which shall be surveyed
relative to a common datum.
b. Volatile organic compounds (VOCs) shall be analyzed using one of the following
methods:
i. Standard Method 6230D (PQL at 0.5 µg/L or less),
ii. Standard Method 6210D (PQL at 0.5 µg/L or Iess),
iii. EPA Method 8021 (Low Concentration, PQL at 0.5 µg/L or less),
iv. EPA Method 8260 (Low Concentration, PQL at 0.5 µg/L or less), or
v. Another method with prior approval by the Groundwater Section Chief.
Any of the referenced methods used for VOCs shall, at a minimum, include all of the
constituents listed in Table VHI of Standard Methods 6230D. The method used shall
provided a PQL at 0.5 µg/L or Iess, 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 (i.e.,
estimated) and reported.
If any VOCs are detected by the methods listed, then the Groundwater Section Supervisor
of the Division's Washington Regional Office at telephone number [phone] shall
be contacted immediate for further instructions regarding any additional follow-up
sampling/analysis required. The results of all initial and follow-up sampling/analysis shall
be submitted simultaneously.
c. If total organic carbon (TOC) concentrations greater than 10 milligrams per liter are detected in
any downgradient groundwater 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 well exceeds 10 milligrams per liter, this
concentration shall be taken to represent the naturally -occurring TOC concentration. Any
exceedances of this naturally -occurring TOC concentration in downgradient wells shall be
subject to the additional sampling and analysis as described in this permit.
d. Any laboratory selected to analyze parameters shall be Division -certified for those
parameters required.
2. Reporting/Documentation Reguirements:
a. The results of the sampling and analysis shall be received on the most -recent version of
"Groundwater Quality Monitoring: Compliance Report Form" (i.e., GW-59 Form) with
copies of the laboratory analyses attached by the Division's Groundwater Section on or
before the last working day of the month following the sampling month.
14

b. All reports shall be mailed to the following address:
NCDENR-DW Q
Groundwater Section
Permits and Compliance Unit
1636 Mail Service Center
Raleigh, NC 27699-1636
Updated blank reporting forms may be downloaded from the web site for the Division's
Groundwater Section at http://gw.ehnr.state.nc.us/ or requested from the address listed
above.
Land Application Site Reguireixaents:
a. Each land application site identified with a GW-A in the most recently -certified
Attachment B of this permit is dominated by soils with a mean seasonal high water table
greater than three feet below the Iand surface. Residuals land application and wastewater
effluent irrigation events may occur on these sites throughout the year.
b. Each land application site identified with a GW-B in the most recently -certified
Attachment B of this permit is dominated by soils with a mean seasonal high water table
between one and three feet below the land surface. Residual land application and
wastewater effluent irrigation events on these sites shall be prohibited from December
through March, inclusive. No residuals shall be land applied or wastewater effluent shall
be irrigated to these sites when the vertical separation between the depth of residuals land
application and the water table is less than three feet. The actual water table depth for
seasonally -restricted soils shall be verified by soil borings or by water level readings
obtained from groundwater monitoring wells near the site within 24 hours prior to any
residuals land application event that occurs from April through November, inclusive. The
number of borings advanced shall be sufficient to characterize water table conditions
across the land application site adequately. Any open borings shall be properly filled with
native soil, prior to the residuals land application event, to decrease the chance of any
residuals or wastewater effluent contaminating the groundwater.
4. Applicable Boundary Requirements:
a. The COMPLIANCE BOUNDARY for residuals land application programs is specified by
regulations in 15A NCAC 2L (i.e., "Groundwater Classifications and Standards"). The
Compliance Boundary for each land application site is established at either 250 feet from
the residuals land application area or 50 feet within the property boundary, whichever is
closest to the residuals land application area. An exceedance of Groundwater Quality
Standards at or beyond the Compliance Boundary is subject to immediate remediation
action according to 15A NCAC 2L .0106 (d)(2).
b. The REVIEW BOUNDARY shall be established around each land application site
midway between the Compliance Boundary and the perimeter of the residuals land
application area. Any exceedance of Groundwater Quality Standards at the Review
Boundary shall require action in accordance with 15A NCAC 2L .0106 (d)(2).
5. Additional Requirements:
a. Any groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.

V. INSPECTIONS
Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to ensure
proper operation of the residuals storage, transport, and application facilities and wastewater
effluent irrigation facilities.
2. Prior to each residuals land application and/or wastewater effluent irrigation event, the
Permittee or his designee shall inspect the residuals storage, transport, and application
facilities and/or wastewater effluent irrigation facilities as appropriate to prevent malfunctions
and deterioration, operator errors, and discharges that may cause or lead to the release of
wastes to the environment, a threat to human health, or a nuisance. The Permittee shall
maintain an inspection log or summary including at least the date and time of inspection,
observations made, and any maintenance, repairs, or corrective actions taken by the Permittee.
This log of inspections shall be maintained by the Permittee for a period of five years from the
date of the inspection and shall be made available to the Division or other permitting authority,
upon request.
Any duly authorized officer, employee, or representative of the Division may, upon
presentation of credentials, enter and inspect any property, premises, or place on or related to
the land application sites or facilities at any reasonable time for the purpose of determining
compliance with this permit; may inspect or copy any records that must be kept under the
terms and conditions of this permit; and may obtain samples of groundwater, surface water, or
leachate.
