7. Specific residuals land application area boundaries shall be clearly marked on each land application
site prior to and during a bulk 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:
a. North Carolina Historical Data for specific crop and soil types as provided by North Carolina
State University Department of Soil Science Webpage at:
http : //www.soil.ncsu.edti/nma/ncnmwg/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 rive 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:
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:
hl!p,//www.enr.state.nc.us/DSWC/pages/p-uidance 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: f!p:Hft-D-fc.sc.egov.usda.gov/IA/tecluiical/N590 03-
2001.i)df.
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.
9. If the land application sites are to be overseeded (e.g., berrnuda 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.

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
i 1. 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.

I. This permit shall become voidable unless the activities of the class A residuals management program
are carried out in accordance with the conditions of this permit, the supporting materials, and in the
manner approved by the Division.
2. This permit shall be effective only with respect to the nature and volume of residuals described in the
application and other supporting data,
3. Failure to abide by the conditions and limitations contained in this permit may subject the Permittee
to an enforcement action by the Division in accordance with North Carolina General Statutes § 143-
215.6A through § 143-215.6C.
4. The annual administering and compliance fee shall be paid by the Permittee within 30 days after
being billed by the Division. Failure to pay the fee accordingly may cause the Division to initiate
action to revoke this permit, as specified by 15 NCAC 2T .0105 (e).
5. The issuance of this permit does not exempt the Permittee from complying with any and all statutes,
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

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.
