WQ0016966 Version 3.0 Shell Version 200201 Page 3 of 12

10. 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 detennined Realistic Yield Expectations(RYE)using any of the following methods:

shall be kept on file and reprinted every five years in accordance with Condition IV.6.
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:

Carolina Department of Agriculture and Consumer Services, the Natural Resource
Conservation Service, or other agronomist.

d. If the RYE and appropriate nutrient application rates cannot be determined, the Permittee shall
contact the Division to determine necessary action.
[15A NCAC 02T.1109(a)(1)(K)]
11. When residuals are land applied to grazed pasture, hay crop realistic nitrogen rate shall be reduced by
25%. [15A NCAC 02T .0108(b)(1)(A)]
12. If residuals 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. [15A NCAC 02T.0108(b)(1)(A)]
13. Prior to land application of residuals containing a sodium adsorption 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. [15A NCAC
02T .0108(b)(1)(A)]
14. Residuals land application fields permitted on or after December 30, 1983 have a compliance boundary
that is either 250 feet from the residual land application area, or 50 feet within the property boundary,
whichever is closest to the residual land application area. Any exceedance of groundwater standards
at or beyond the compliance boundary shall require corrective action. Division-approved relocation of
the compliance boundary shall be noted in Attachment B. Multiple contiguous properties under
common ownership and permitted for use as a disposal system shall be treated as a single property with
regard to determination of a compliance boundary. [15A NCAC 02L .0106(d)(2), 02L .0107(b), 02T
.0105(h),G.S. 143-215.1(i), G.S. 143-215.1(k)]
WQ0016966 Version 3.0 Shell Version 200201 Page 4 of 12

15. The review boundary is midway between the compliance boundary and the residual land application
area. Any exceedance of groundwater standards at or beyond the review boundary shall require
preventative action. [15A NCAC 02L .0106(d)(1), 02L .0108]
III. OPERATION AND MAINTENANCE REQUIREMENTS
1. The Permittee shall operate and maintain the residuals management program as a non-discharge system.
