1. The Permittee shall operate and maintain the subject residuals management program so there is no
discharge to surface waters, nor any contravention of groundwater or surface water standards. In the
event the residuals management program does not perform as permitted, including the creation of
nuisance conditions due to improper operation and maintenance, or failure of the land application areas
to assimilate the residuals, the Permittee shall immediately cease land applying residuals, take
immediate corrective actions, and contact the Raleigh Regional Office supervisor. [15A NCAC 02T
.0108(b)(1)(A)]
2. This permit shall not relieve the Permittee of its responsibility for contravention of groundwater or
surface water standards resulting from the operation of this residuals management program. [15A
NCAC 02T .0108(b)(1)(A)]
3. The Permittee shall not land apply residuals to the sites listed in Attachment B when the residual
pollutant concentrations exceed the following on a dry weight basis:
Parameter
Ceiling
Concentration Cumulative Pollutant Loading Rates

6. The Permittee shall not apply residuals or other sources of Plant Available Nitrogen (PAN) to the sites
listed in Attachment B in exceedance of agronomic rates. The Permittee shall calculate agronomic rates
using the expected nitrogen requirements based on Realistic Yield Expectations (RYE). The Permittee
shall determine RYE using one of the following methods:
a. Division-approved site-specific historical data for specific crops and 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 crops and soil types as provided by the North Carolina
Cooperative Extension.
c. A Crop Management Plan as outlined by the North Carolina Cooperative Extension, the North
Carolina Department of Agriculture and Consumer Services, the Natural Resource Conservation
