I 1. Bulk residuals and other sources of Plant Available Nitrogen (PAN) shall not be applied in
exceedance of agronomic rates. Appropriate agronomic rates shall be calculated using expected
nitrogen requirements based on the determined Realistic Yield Expectations (RYE) using any of the
following methods:
a. Division's pre -approved site specific historical data for specific crop or soil types by calculating
the mean of the best three yields of the last five consecutive crop harvests for each field.
b. North Carolina Historical Data for specific crop and soil types as provided by North Carolina
State University Department of Soil Science (http://nutrients.soil.nesu.edglyields/index.php).
A copy shall be kept on file and reprinted. every five years in accordance with Condition N.7.
c. If the RYE cannot be determined using methods (a) or (b) above, the Permittee may use the RYE
and appropriate nutrient application 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 the Senate Bill 1217 Interagency Group _ Guidance
Document: Chapter I
(http://www.ncagr.gov/SWC/tech/documents/9tli Guidance Doc 100109. d .
iii. Certified Nutrient Management PIan as outlined by the Natural Resources Conservation
Services (MRCS). These plans must meet the USDA -MRCS 590 Nutrient Management
Standards It :lI-fc.se.e ov.usda. ov/NH I ractice-standards/standards/590. d .
d. If the RYE and appropriate nutrient application rates cannot be determined, the Permittee shaII
contact the Division to determine necessary action.
12. When residuals are land applied to grazed pasture, hay crop realistic nitrogen rate shall be reduced by
25% in accordance with the USDA-NRCS 590 Nutrient Management Standards.
13. If land application sites are to be over -seeded or double -cropped (e.g., bermuda grass in the summer
and rye grass in the winter with both crops to receive residuals), then the second crop can receive an
application of PAN at a rate not to exceed 50 pounds per acre per year (lbs/ac/yr). This practice may
be allowed as long as the second crop is to be harvested or grazed. If the second crop is to be planted
for erosion control only and is to be tilled into the soil, then no additional PAN shall be applied.
14. Dior to land application of residuals containing a sodium adso*lption ratio (SAR) of 10 or higher, the
Permittee shall obtain and implement recommendations from at least one of the following: the local
Cooperative Extension Office; the Department of Agriculture and Consumer Services; the Natural
Resource Conservation Service; a North Carolina Licensed Soil Scientist; or an agronomist. The
recommendations shall address the sodium application rate, soil amendments (e.g., gypsum, etc.), or a
mechanism for maintaining site integrity and conditions conducive to crop growth. The Permittee
shall maintain written records of these recommendations and details of their implementation.
15. The compliance boundary for residual land application sites shall be specified in accordance with
15A NCAC 02L .0107(b). These sites were individually permitted on or after December 30, 1983;
therefore, the compliance boundary is established at either 250 feet from the residual Iand application
area, or 50 feet within the property boundary, whichever is closest to the residual land application
area. An exceedance of groundwater standards at or beyond the compliance boundary is subject to
remediation action according to 15A NCAC 02L .0106(d)(2) as well as enforcement actions in
accordance with North Carolina General Statute 143-215.6A through 143-215.6C. Any approved
relocation of the COMPLIANCE BOUNDARY will be noted in Attachment B.
W00036561 Version 1.0 Shell Version 130607 Pace 4 of 12

16. In accordance with 15A NCAC 02L.0108, the review boundary shall be established midway between
the compliance boundary and the residual land application area. Any exceedance of groundwater
standards at the review boundary shall require action in accordance with 15A NCAC 02L .0106.
IIL OPERATION AND MAINTENANCE REQUIREMENTS
1. The residuals management program shall be properly maintained and operated at all times. The
program shall be effectively maintained and operated as a non -discharge system to prevent any
contravention of surface water or groundwater standards.
2. The Winston-Salem Regional Office, telephone number [phone], and the appropriate local
government official (i.e., county manager, city manager, or health director) shall be notified at least
48 hours prior to the initial residuals land application to any new land application site. Notification to
the Aquifer Protection Section's regional supervisor shall be made from 8:00 a.m. until 5:00 p.m. on
Monday through Friday, excluding State Holidays.
3. The Winston-Salem Regional Office shall be notified via email or telephone, [phone], at least
24 hours prior to conducting .any land application activity. Such notification shall indicate, at a
minimum, the anticipated application times, field IDs, and location of land application activities. If it
becomes necessary to apply to additional fields due to unforeseen events, the Regional Office shall be
notified prior to commencing the application to those fields.
4. The Permittee shall maintain an approved Operation and Maintenance Plan (O&M Plan) pursuant to
15A NCAC 02T .1110. Modifications to the O&M Plan shall be approved by the Division prior to
utilization of the new plan. The O&M Plan, at the minimum, shall include:
a) Operational functions;
b) Maintenance schedules;
c) Safety measures;
d) Spill response plan;
e) Inspection plan including the following information:
i. Names and/or titles of personnel responsible for conducting the inspections;
ii. Frequency and location of inspections, including those to be conducted by the ORC, and
procedures to assure that the selected locations) and inspection frequency are representative
of the residuals management program; %
iii. Detailed description of inspection procedures including recon keeping and actions to be
taken by the inspector in the event that noncompliance is observed pursuant to the
noncompliance notification requirements under the monitoring and reporting section of the
permit;
fj Sampling and monitoring plan including the following information:
i. Names and/or titles of personnel responsible for conducting the sampling and monitoring;
ii. Detailed description of monitoring procedures including parameters to be monitored;
iii. Sampling frequency and procedures to assure that representative samples are being collected.
Fluctuation in temperature, flow, and other operating conditions can affect the quality of the
residuals gathered during a particular sampling event. The sampling plan shall account for
any foreseen fluctuations in residuals quality and indicate the most limiting times for
residuals to meet pathogen and vector attraction reduction requirements (e.g. facilities that
land apply multiple times per year but have an annual sampling frequency, may need to
sample during winter months when pathogen reduction is most likely to be negatively
affected by cold temperatures).
