In accordance with your permit renewal and modification request received June 25, 2007, and
subsequent additional information received August 20, 2007, we are forwarding herewith Permit No.
W00006101, dated October 10, 2007, to the City of Dunn for the continued operation of the subject land
application of residuals solids program.
It should be noted that the package submitted to apply for this permit renewal was
submitted after the expiration date of the previous issuance of this permit (i.e., submittal date of
June 25, 2007 versus an expiration date of November 30, 2006). The Permittee should make a
better effort to monitor permit expiration dates in the future to avoid potential enforcement action
for failing to submit a timely renewal as well as operating the residuals land application program
without a valid permit.
In this permit, a total of 174.6 acres are being renewed, 1309.78 acres of existing land are being
deleted, 114.5 acres are being transferred from the Town of Cary's residuals land application program and
121.8 acres of new land are being added with a new total of 410.9 acres of permitted land.
This permit shall be effective from the date of issuance until September 30, 2012, shall void
Permit No. W00006101 issued December 7, 2001, and shall be subject to the conditions and limitations
as specified therein. 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. Of special interest to you may be the following:
♦ Condition Ll., No later than six months prior to the expiration of this permit, the Permittee
shall request renewal of this permit on official Division forms.
♦ Condition 11.14. and 15., The appropriate local governmental official and the Aquifer
Protection Section of the appropriate Division's regional office shall be notified at least 24
hours prior to the initial residuals land application event to any new land application site.

9. Residuals and other sources of Plant Available Nitrogen (PAN) shall be land applied to all land
application sites at or below agronomic rates. Appropriate agronomic rates shall be calculated using
expected nitrogen requirements based on the Realistic Yield Expectations (RYE) for each approved
land application site. Realistic Yield Expectations for crop types and specific fields or soils types
shall be determined by using any of the following methods:
a. North Carolina Historical Data for speck crop and soil types as provided by North Carolina
State University Department of Soil Science. The Department webpage is located at:
htti)://www.soil.ncsli.edu/mni)/ncrunwg/viel
b. Site Specific Historical Data for crop types on specific fields or soil types by calculating the
mean of the best three yields of the last five consecutive crop harvests for each field.
C. If the RYE cannot be determined using methods 9(a) or (b) above, RYE can be established
from specially developed soil interpretation records for Nutrient Management Planning, Farm
Service Agency Records, university trials, or inference from crop performance on soil with
very similar physical and chemical features.
d. Realistic Yields Expectations and acceptable nitrogen application rates that use the above
methodology are required parts of many agricultural planning documents. The Permittee may
use the RYE and appropriate agronomic rates reported in any of the following documents:
i. Crop management plan as outlined by the local Cooperative Extension Office, the North
Carolina Department of Agriculture and Consumer Services, the Natural Resource
Conservation Service, or other agronomist.
ii. Waste Utilization Plan as outlined by Senate Bill 1217 Interagency Group- Guidance
Document: Chapter 1. Guidance for the completion of the plan can be found at:
btip://www.enr.state.nc.us/DSWC/Dages/guidance docs html
iii. Certified Nutrient Management Plan as outlined by Natural Resources Conservation
Services (MRCS). These plans must meet the USDA-NRCS 590 Nutrient Management
Standards, which are available at:
ftp://fto-fc.sc.egov.usda goy/NHO/practice-standards/standards/590 pdf
e. For any crop type for which the RYE and appropriate nitrogen application rate cannot be
determined, the Permittee shall contact the Division to determine necessary action.
10. If the land application sites are to be overseeded (e.g., bermuda grass in the summer and rye grass in
the winter with BOTH crops to receive residuals), then the second crop shall receive an application
of PAN at a rate of no greater than 50 pounds per acre per year. This practice shall be allowed as
long as the second crop is to be harvested. If the second crop is to be planted for erosion control
only and is to be tilled into the soil, then no residuals shall be land applied to these sites because the
PAN will essentially be returned to the soil.
Prior to application of PAN to permitted sites at rates exceeding the agronomic rate, the Permittee
must submit and receive approval by the Division.
WQ0006101 Version 3.0 Shell Version 070228 Page 4 of 14

11. Should any of the residuals generated by the residuals source -generating facilities listed in the most
recently -certified Attachment A of this permit contain a high salt content (i.e., high sodium
adsorption ratio (SAR) of ten (10) or higher), the Permittee shall obtain and implement
recommendations from the local Cooperative Extension Office, the Department of Agriculture and
Consumer Services, the Natural Resource Conservation Service, a North Carolina -licensed Soil
Scientist, or other agronomist regarding sodium application rate, soil amendments (e.g., gypsum,
etc.) or other ameliorative mechanism for maintaining the integrity of the site in terms of suitability
for land application of residuals and maintaining conditions conducive to crop growth. The
Permittee shall maintain written records of each monitoring event that includes details of the sites
covered and rate of soil amendment application.
12. 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. Per 15A NCAC 2T .0105(h), upon the request by the Permittee the Compliance
Boundary may be located closer to the waste disposal area (provided the groundwater standards can
be met at the newly established Compliance Boundary). Any approved relocation of the
COMPLIANCE BOUNDARY will be noted in the most recently -certified Attachment B of this
permit. An exceedance of Groundwater Standards at or beyond the Compliance Boundary is subject
to remediation action according to 15A NCAC 2L .0106(d)(2) as well as enforcement actions in
accordance with North Carolina General Statute 143-215.6A through 143-215.6C.
13. 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
15ANCAC 2L.0106 (d)(1).
14. The appropriate local governmental official (i.e., county manager, city manager, etc.) shall be
notified at least 24 hours prior to the initial residuals land application event to any new land
application site. In addition, the appropriate county manager's office shall be notified prior to the
initial residuals land application event on any new site so that they will be aware that residuals land
application activities have commenced on the site.
15. The Aquifer Protection Section of the appropriate Division's regional office shall be notified at least
24 hours prior to the initial residuals land application event on any new land application site. Such
notification to the Regional Aquifer Protection Supervisor shall be made during normal office hours
(i.e., from 8:00 a.m. until 5:00 p.m.) between Monday and Friday, but excluding State Holidays. A
list of the Division's regional offices, their county coverage, and their contact information may be
downloaded from the web site at htto://www.enr.state.nc.us/html/reeionaloffices.html.
III. OPERATION AND MAINTENANCE REQUIREMENTS
1. The residuals land application program shall be effectively maintained and operated at all times as a
non -discharge system to prevent the discharge of any wastes resulting from the operation of this
program. The Permittee shall maintain an Operation and Maintenance Plan pursuant to 15A NCAC
02T .1110 including operational functions, maintenance schedules, safety measures, and a spill
response plan.
WQ0006101 Version 3.0 Shell Version 070228 Page 5 of 14

2. In the event that the residuals land application program is not operated satisfactorily, including the
creation of nuisance conditions, the Permittee shall cease land applying residuals to the site, contact
the Aquifer Protection Section of the appropriate Division of Water Quality's (Division) regional
office, and take any immediate corrective actions as may be required by the Division.
Upon classification of the residuals land application program by the Water Pollution Control System
Operators Certification Commission (WPCSOCC), the Permittee shall designate a certified land
application/residuals operator to be in responsible charge (ORC) of the program. The operator shall

Permittee shall also designate a certified back-up operator of the appropriate type to comply with the
conditions of 15A NCAC 8G .0201.
4. This permit shall become voidable if the soils of the land application sites fail to assimilate the
residuals or the application causes contravention of surface water or groundwater standards and may
be rescinded unless the land application sites are maintained and operated in a manner that will
protect the assigned water quality standards of the surface waters and groundwater.
5. A copy of this permit shall be maintained in all manned equipment at the land application sites when
residuals are being land applied during the life of this permit. The spill prevention and control plan
shall be maintained in all residuals transport and application vehicles.
6. Adequate provisions shall be taken to prevent wind erosion and surface runoff from conveying
residuals from the land application sites onto adjacent properties or into any surface waters.
Adequate procedures shall be provided to prevent surface runoff from carrying any land applied or
stored residuals into any surface waters.
No residuals shall be stored at any land application site at any time, unless written approval has first
been requested and obtained from the Division.
9. Bulk residuals shall not be applied to the land under the following conditions:
a. If the residuals are likely to adversely affect a threatened or endangered species listed under
section 4 of the Endangered Species or its designated critical habitat;
b. If the application causes prolonged nuisance conditions;

h. If the pH is not maintained in the soil,. residuals, and lime mixture, greater than 6.0, on land
application sites onto which residuals are applied. Residuals may be applied to the sites
provided that sufficient amounts of lime is also applied to achieve a final pH of the soil mixture
of at least 6.0, or if an agronomist provides information indicating that the pH of the soil,
residuals, and lime mixture is suited for the specified crop type. Any approved variations to the
acceptable soil pH (6.0) for land application will be noted in the most recently certified
Attachment B of this permit.
i. If the land does not have an established vegetative cover in accordance with the crop
management plan outlined by the local Cooperative Extension Office, the Department of
Agriculture and Consumer Services, the Natural Resource Conservation Service, or other
agronomist unless the bulk residuals are incorporated within a 24-hour period following the
residuals land application event or injected (This requirement does not apply to no -till
fields);
j. If the vertical separation of the seasonal high water table and the depth of residuals application is
less than one foot;
k. If the vertical separation of the depth to bedrock and the depth of residuals application is less

land surface (e.g., tobacco, melons, cucumbers, squash, etc.) shall not be harvested for 14
months after any residuals land application event;
d. 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 any residuals land application
event when the residuals remain on the land surface for four months or longer prior to
incorporation into the soil;
e. Food crops with harvested parts below the surface of the land shall not be harvested for 38
months after any residuals land application event when the residuals remain on the land surface
for less than four months prior to incorporation into the soil;
f. Turf grown on land where residuals are applied shall not be harvested for 12 months after any

WO0006101 Version 3.0 Shell Version 070228 Page 7 of 14

12. This permit shall become voidable unless the agreements between the Permittee and the landowners
and lessees or operators of any land application sites listed in the most recently -certified Attachment
B of this permit not owned by the Permittee are in full force and effect. These agreements shall be
considered expired concurrent with the expiration date of the permit and shall be renewed at the
same time the permit is renewed.
13. Upon entering an agreement with landowners to apply residuals to a land .application site, the
Permittee shall require of the landowner or lessee/operator a statement detailing the volume of
nutrient sources (waste residuals, manufactured fertilizers, manures, or other animal waste products)
other than the residuals to be applied by the Permittee, that have been applied to the land, and a copy
of the most recent Nutrient Management Plan (NMP), if available, for the fields within the
agreement. For the purpose of this permit condition, a Crop Management Plan (CMP), Waste
Utilization Plan (WUP) or Certified Nutrient Management Plan (CNMP) shall also be
considered a Nutrient Management Plan.
The NMPs must be provided only for those operations where a NMP is required by the US
Department of Agriculture — National Resources Conservation Service (MRCS) or other State
Agencies. The Permittee shall rely on the provided information to calculate appropriate reductions
in allowable nutrient loading rates. If the calculation shows that the agronomic rates in the NMP
(including PAN) have already been met or exceeded on a field, no additional residuals shall be land
applied to that field.
W. 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. Residuals generated by each residuals source -generating facility listed in the most -recently -certified
Attachment A of this permit shall be analyzed to demonstrate that they are non -hazardous under the
Resource Conservation and Recovery Act (RCRA). A corrosivity, ignitability, and reactivity
analysis as well as a Toxicity Characteristics Leaching Procedure (TCLP) analysis shall be
conducted on residuals generated by each residuals source -generating facility listed in the most
recently -certified Attachment A of this permit. The analyses shall be performed at the frequency
specified in the most recently -certified Attachment A of this permit, and the results shall be
maintained on file by the Permittee for a minimum of five years.
If residuals generated by a particular residuals source -generating facility are insufficient to require a
land application events during a required sampling period as specified in the most recently -certified
Attachment A of this permit (e.g. no land application occur during an entire year when annual
monitoring is required), no sampling data is required during the period of inactivity. The Permittee
shall submit an annual report, as required in condition IV. 10., even in the event that no land
application events occur during an entire year, the annual report shall include an explanation for
missing sampling data.
Only residuals that are generated by the residuals source -generating facilities that are identified as
being exempt from this condition in the most recently -certified Attachment A of this permit shall not
be required to comply with this monitoring requirement.

[FOR 503 TYPE RESIDUALS] If residuals generated by a particular residuals source -generating
facility are insufficient to require a land application events during a required sampling period as
specified in the most recently -certified Attachment A of this permit (e.g. no land application occur
during an entire year when annual monitoring is required), the Permittee shall make up the missed
sampling either by taking additional samples during land application events previous to a planned
period of inactivity or by taking additional samples during land application events immediately
following the period of inactivity. The Permittee shall submit an annual report, as required in
condition IV. 10, even in the event that no land application events occur during an entire year; the
annual report shall include an explanation of additional sampling data intended to compensate for
periods of inactivity, or an explanation for missing sampling data

Protection Agency (EPA) certification statements concerning compliance with pathogen reduction
requirements, vector attraction reduction requirements, and management practices shall be
completed at the frequency specified in the most recently -certified Attachment A of this permit 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 H. 6. in the most recently -certified Attachment A of this permit shall not be
required to comply with this monitoring requirement.
5. A representative annual soils analysis (i.e., Standard Soil Fertility Analysis) shall be conducted on
each land application site on which a residuals land application event in the respective calendar year
has occurred or is to occur, and the results shall be maintained on file by the Permittee for a
minimum of five years. The Standard Soil Fertility Analysis shall include, but is not necessarily
limited to, the following parameters:
Acidity Exchangeable Sodium Percentage (by calculation)
Calcium Magnesium Phosphorus
Cation Exchange Capacity Manganese Potassium
Copper Percent Humic Matter Sodium

formal permit request shall be submitted to the Division documentation from the parties involved
and other supporting materials as may be appropriate. The approval of this request shall be
considered on its merits and may or may not be approved.
Permit issued this the 101 day of October, 2007.
