application event. [15A NCAC 02T .0108(b)(1)]
12. 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.ph�p}.

25% in accordance with the USDA-NRCS 590 Nutrient Management Standards. [15A NCAC 02T
.0108(b)(1)]
14. If land application sites are to be over -seeded or double -cropped (e.g., bennuda 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

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)]
16. 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 Iand 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)]
17. 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 RE UIREMENTS
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. [ 15A NCAC 02T .1110]

1. 3 x Year monitoring shall be conducted in March, July & November; Annual monitoring shall be conducted every November.
2. The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement
of pH shall be made after purging and prior to sampling for the remaining parameters.
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top
of casing) of all monitoring wells shall be surveyed relative to a common datum.
4. VoIatile Organic Compounds (VOC) — In November only, analyze by one of the following methods:
a, Standard Method 6230D, PQL at 0.5 µg/L or less
b. Standard Method 62101), PQL at 0.5 µg/L or Iess
c. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less
e. Another method with prior approval by the Water Quality Permitting Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWQ certified to run any method used.
b. The method used must, at a minimum, include all the constituents listed in Table Vill of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 pg/L. or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents
detected above the MDL but below the PQL of 0.5 gg/L must be qualified (estimated) and reported.
5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Raleigh Regional Office supervisor, telephone number [phone],
must be contacted within 5 days of receipt of results for further instructions regarding any additional follow-up analyses required.
6. If TOC concentrations greater than 10 mg/l are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents
comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/l, this concentration will be taken to represent the naturally occurring
TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above.
7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 21 and this attachment.
8. Monitoring wells MW2 and MW4 are to be permanently abandoned consistent with Condition I.3.
