7. Specific residuals land application area boundaries shall be clearly marked on each land application
site prior to and during a residuals land application event.
8. Bulk 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 the following methods:
North Carolina Historical Data for specific crop and soil types as provided by North Carolina
State University Department of Soil Science Webpage at:
hLtp://www.soil.ncsu.edu/nmp/ncnmw.g/-vieldsl
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 I1.8.a. or II.8.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 Utluz",. on Plan as outlined by Senate Bill 1217 Interagency Group Guidance
Document: Chapter 1. Guidance for the completion of the plan can be found at:
http://www.enr.state,nc.us/DSWC/pages/.guidance docs.html.
iii. Certified Nutrient Management Plan as outlined by Natural Resources Conservation
Services (MRCS). These plans must meet the USDA -MRCS 590 Nutrient Management
Standards, which are available at: ftp:/lftp-fc.se.e,Gov_.us_da.gov/IA/technical/N590 03-
2001.pdf.
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.
If the land application sites are to be over -seeded (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.
WQ0031712 Version 1.0 Shell Version 070228 Page 3 of 11

10. 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 five (5) or higher), the exchangeable sodium percentage (ESP) or other method as
approved by the Division, using the results from the annual soils analysis as required by this permit,
shall be monitored on all of the land application sites. 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 shall review the results and make
recommendations regarding 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 implement such
recommendations accordingly and shall maintain written records of each monitoring event that
includes details of the sites covered and rate of soil amendment application.
11. 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.
12. 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)(1).
13. The appropriate local governmental official (i.e., county manager, city manager, etc.) shall be notified
at least 24 hours prior to the initial bulk 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.
14, The Aquifer Protection Section of the appropriate Division's regional office shall be notified at least
24 hours prior to the initial bulk 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

j. if the vertical separation of the depth to bedrock and the depth of residuals application is less than
one foot;
11. This permit shall become voidable unless the agreements between the Permittee and the landowners
and lessees or operators of any land application sites 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.
12. 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 (also CMP, WUP, or CNMP) is
required by the US Department of Agriculture -- National Resources Conservation Service (NRCS) 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
(including PAN) have already been met or exceeded on a field, no additional residuals shall be land
applied to that field.

Attachment A of this permit, an analysis is not required for that sampling period. The Permittee is
still responsible for submitting an annual report even in the event that no land application events
occur during an entire year..
After the residuals generated by a particular residuals source generating facility have been monitored
for two years at the frequency specified in the most recently certified Attachment A of this permit, the
Permittee may subunit a request to the Division for a permit modification to 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. Residuals generated by each residual source generating facility listed in the most recently certified
Attachment A of this permit shall be monitored for compliance with Condition II. 3. The monitoring
shall be performed at the frequency specified in the most recently certified Attachment A of this
permit, and data to verify pathogen reduction of the residuals shall be maintained on file by the
Permittee for a minimum of five years. 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
requirements and site restrictions in 15A NCAC 02T .1106 (a) and (b) shall be met. In addition, the
Erivironmental Protection Agency (EPA) certification statements concerning compliance with
pathogen 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 I1. 3.
in the most recently certified Attachment A of this permit shall not be required to comply with this
monitoring requirement.

rules, regulations, or ordinances, which may be imposed by other government agencies (local, state,
and federal) that have jurisdiction. Of particular concern to the Division are applicable river buffer
rules in 15A NCAC 02B .0200, erosion and sedimentation control requirements in 15A NCAC
Chapter 4 and under the Division's General Permit NCG010000, and any requirements pertaining to
wetlands under 15A NCAC 02B .0200 and 02H .0500.
6. This permit may be modified, revoked, and/or reissued to incorporate any conditions, limitations and
monitoring requirements the Division deems necessary in order to protect the environment and public
health adequately.

residuals management program to change ownership or to change the name of the Permittee, a 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.
