pathogen requirements and site restrictions in 15A NCAC 02T .1106 (a) and (b), and one vector
attraction reduction requirement in 15A NCAC 02T .1107 (a) 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. 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 shall not
be required to comply with the specified pathogen reduction and vector attraction reduction
requirements.
5. For residuals treatment and storage facilities, the following minimum setbacks shall be maintained
(all distances in feet):
i. Any habitable residence or place of public assembly under separate ownership: 100
ii. Any property line: 50
iii. Any private or public water supply source: 100
iv. Surface waters: 50
v. Any well with exception of monitoring wells: 100

iii. Surface water diversions: 75 0
iv. Groundwater lowering ditches: 25 0
v. Any well with exception of monitoring wells: 100 100
vi. Bedrock outcrops: 25 0
Unless otherwise noted in Attachment A of this permit, "cake" residuals are residuals that have
greater than 15% solids by weight and can be stacked without flowing, and handled, transported and
spread as a solid (i.e., using a backhoe, front end loader, slinger spreader, broadcast spreader or other
equipment designed for handling solid materials) without leaving any significant liquid fraction
behind.
7. Specific residuals land application area boundaries shall be clearly marked on each land application
site prior to and during a bulb 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 of the following methods:
a. North Carolina Historical Data for specific crop and soil types as provided by North Carolina
State University Department of Soil Science. The Department webpage is located at:
http://nutrients.soil.ncsu.edu/yields/
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 8(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:
h ://www.enr.state.ne.us/DSWCI a es/ idance docs.html.
iii. Certified Nutrient Management Plan as outlined by Natural Resources Conservation
Services (NRCS). These plans must meet the USDA-NRCS 590 Nutrient Management
Standards, which are available at:
ftp://ftp-fc.se.e og v.usdai4ov/NHQ/practice-standards/standards/590.pdf
c. 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.
WQ0034833 Version 1.0 Shell Version 090204 Page 3 of 12

9. If the land application sites are to be overseeded or doublecropped (e.g., bermuda grass in the summer
and rye grass in the winter with BOTH crops to receive residuals or corn and small grain both 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 rates, the Permittec
must submit and receive approval by the Division.
10, The Permittee shall not distribute Class A residuals that contain a high salt content (i.e., high sodium
adsorption ratio (SAR) of ten (10) or higher) without prior written approval from the Division. The
Permittee may seek approval by demonstrating program adjustments have been made to assure that
the person accepting the residuals is aware of the effects of the high salt content, the proper
application rates of the residuals, and any other operational considerations for proper application to
assure that the high salt content will not adversely impact the receiving sites.
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).
III. OPERATION AND MAINTENANCE REQUIREMENTS
The class A residuals management 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.
2. In the event that the Class A residuals management program is not operated satisfactorily, including
the creation of nuisance conditions due to improper operation and maintenance, the Permittee
immediately shall either cease land applying or cease distribution of residuals to the sites impacted.
In addition, the Permittee shall contact the Aquifer Protection Section of the appropriate Division
regional office, and take any immediate corrective actions as may be required by the Division.
These action(s) do not prevent the Division from subsequently taking actions in response to the above
violation consistent with the condition of this permit, North Carolina Administrative Code rules,
regulations and the NC General Statutes.
WQ0034833 Version 1:0 Shell Version 090204 Page 4 of 12

3. The Permittee shall maintain an approved Operation and Maintenance Plan (O&M Plan) pursuant to
15A NCAC 02T .1110 including operational functions, maintenance schedules, inspection plan,
sampling and monitoring plan, safety measures, and a spill response plan. The most recent O&M
plan shall be submitted to the Raleigh Regional Office for review and approval. The sample and
monitoring portion of the plan shall include the following information:
a. Name and positions of personnel responsible for conducting the sampling and monitoring;
b. Sampling frequency specified in Attachment A of the permit;
C. Description of sampling and monitoring procedures;
d. Detailed description of sampling and monitoring procedures for the collection of representative
samples. Fluctuation in temperature, flow and other operating conditions can affect the quality
of the residuals generated during a particular sampling event, The sampling plan must account
for potential fluctuations in residuals quality, and indicate sampling times accordingly to further
demonstrate compliance during the most limiting times (e.g. small facilities that apply multiple
times per year, but have an annual sampling frequency may need to sample and document
compliance with the pathogen reduction requirements during winter months when pathogen
reduction is most likely to be negatively affected by cold temperatures).
4. A utilization agreement between the Permittee and the person or entity agreeing to accept and
distribute Class A bulk residuals shall be in place prior to acceptance of the bulk residual. The
agreement shall specify the responsibilities of the person or entity agreeing to accept and distribute
the Class A bulk residuals. The utilization agreement shall be signed by both the Permittee or his
designee and the person responsible for application of the residuals. The utilization agreement shall
stipulate the following:
a. By agreeing to accept the bulk Class A residuals it is recognized that the application of Class A
residuals is allowed under the conditions of the agreement. The application of the Class A
residuals is considered the beneficial reuse of a waste under 15A NCAC 02T .1100. The
application of the Class A residuals to the land has been deemed permitted under 15A NCAC
.1103(4) provided the conditions of the agreement are met. Any action resulting in the damages
to surface waters or groundwater caused by failure to follow the conditions of the agreement is
subject to enforcement action by the Division;
b. The person or entity accepting the Class A residuals shall to the best of their knowledge meet the
following application requirements:
i. Application of the bulk residuals will stop if it becomes known that the application
adversely affects a threatened or endangered species listed under section 4 of the
Endangered Species Act;
ii. Application of the bulk residuals shall not occur when the land is flooded, frozen, or
snow-covered or is otherwise in a condition such that runoff of the residuals would occur;
iii. Application of the bulk residuals shall not occur within the 100-year flood elevation
unless the bulk residuals are injected or incorporated within a 24-hour period following
the residuals land application event. Flood elevation information is available at

iv. Application of the bulk residuals shall not occur during a measurable precipitation event
(i.e., >.01" per hour) or within 24 hours following a rainfall event of 0.5 inches or greater
in a 24-hour period;
v. Residuals stockpiled for more than 14 days shall be covered;
vi. Application of the bulk residuals shall not occur if the vertical separation between the
seasonal high water table and the bulk residuals application is less than one foot;

with the agreement;
e. Instructions, including contact information for key personnel, for the applicator or party receiving
bulk residuals in the event that requirements specified in the utilization agreement are not met;
f. A copy of the utilization agreement shall be maintained at the land application sites when bulk
residuals are being applied.
5. Upon classification of the Class A residuals management 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 hold a certificate of the type classification assigned to the program by the WPCSOCC. The
Permittee shall also designate a certified back-up operator of the appropriate type to comply with the
conditions of 15A NCAC SG .0201. ,
6. This permit shall become voidable and maybe rescinded by the Division in the event of failure of the
facility and Class A residuals distribution program to adequately meet the conditions of this permit
and 'protect the assigned water quality standards of the surface waters and groundwater.
7. A copy of this permit or a signed copy of a utilization agreement shall be maintained in all manned
equipment at the land application sites when residuals are being land applied during the life of this
permit. A spill prevention and control plan shall be maintained in all residuals transport and
application vehicles.
8. Adequate provisions shall be taken to prevent wind erosion and surface runoff from conveying bulk
residuals from the land application sites onto adjacent properties or into any surface waters. Such
provisions shall be described and implemented in the operation plan required in Condition IH.2, and

15. For fields receiving bulk residuals, the Permittee shall request 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 purpose of this permit condition, a Crop Management Plan (CMP), 'Waste Utilization
Plan (WUP) or Certified Nutrient Management Plan (CLAMP) shall also be considered a
Nutrient Management Plan.
The NMPs must be provided only for those operations where a NMP (also CMP, WUP, or CLAMP) 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
(including PAN) have already been met or exceeded on a field, no additional residuals shall be land
applied to that field.
16. Where the Permittee directly land applies bulk residuals to land, the Permittee shall supply the
landowner with documentation specifying that land application of the bulk residuals shall occur
consistent with this permit.

residuals of the Performance Standards and Operation and Maintenance Requirements specific to land
application of bulk residuals.
IV. 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

analysis as well as a Toxicity Characteristics Leaching Procedure (TCLP) analysis shall be conducted
on residuals generated by each residual 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 distributed or land applied at a frequency less than that which is specified in
the most recently -certified Attachment A of this permit, the analyses shall be required for each
residuals distribution and land application event. 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.
If residuals generated by a particular residuals source -generating facility are insufficient to require a
land application event 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. 9., 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.
