certified Attachment B of this permit, but were approved with different buffers shall be reflagged to
comply with these buffers. [15A NCAC 02T .02190)(5)]
9. Land application areas shall be clearly marked on each site prior to and during any residuals
application event. [ISA NCAC 02T .0108(b)(1)]
10. 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.ncsu.edu/yields/index.php .

.0108(b)(1)]
12. 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/ae/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)]
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)]
14. These residuals land application sites were individually permitted on or after December 30, 1983;
therefore, the compliance boundary is established at 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. 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. [15A NCAC 02L
.0107(a)]
15. 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. [ 15A NCAC 02L .0108]
III. OPERATION AND MAINTENANCE REQUIREMENTS
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. [I5A NCAC 02T .I 110]
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 regional supervisor shall be made from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays. [15A NCAC 02T .0108(b)(1)]

residuals gathered during a particular sampling event. The sampling plan shall account for
any foreseen fluctuations in residuals quality and indicate the most Iimiting 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).
[ 15A NCAC 02T .1100]
5. Upon the Water Pollution Control System Operators Certification Commission's (WPCSOCC)
classification of the facility, the Permittee shall designate and employ a certified operator in
