regulations in 15A NCAC 2L (i.e., "Groundwater Classifications and Standards"). The Compliance
Boundary for each surface disposal site is established at either 500 feet from the residuals surface
disposal area or at the property boundary, whichever is closest to the residuals surface disposal 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.
4. The REVIEW BOUNDARY shall be established around each surface disposal site midway between
the Compliance Boundary and the perimeter of the residuals surface disposal area. Any exceedance
of Groundwater Quality Standards at the Review Boundary shall require action in accordance with
15A NCAC 2L.0106 (d)(1).
III. OPERATION AND MAINTENANCE REQUIREMENTS
The residuals surface disposal unit shall be effectively maintained and operated at all times as a non -
discharge system to prevent the discharge of any wastes resulting from the operation of this program.
2. In the event that the residuals surface disposal program is not operated satisfactorily, including the
creation of nuisance conditions, the Permittee shall cease land applying residuals to the site, contact
the Aquifer Protection Section of the appropriate Division of Water Quality's (Division) regional
office, and take any immediate corrective actions as may be required by the Division.
A copy of this pen -nit, as well as the post -closure care plan, shall be maintained on site during the
life of this permit.
4. Adequate provisions shall be taken to prevent any surface runoff from occurring from the surface
disposal unit. If runoff cannot be prevented, a collection system shall be installed with the capacity
to handle runoff from a 24-hour, 25 -year storm event. All collected runoff shall be disposed in a
manner approved by the Division.
Adequate provisions shall be taken to prevent wind erosion from conveying pollutants or residuals
from the surface disposal unit onto the adjacent property or into any surface waters.

4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 pg/L or less
b. Standard Method 621 OD, PQL at 0.5 lig/L or less
c. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 pg/L or less
e_ Another method with prior approval by the Aquifer Protection 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 `fable VIII of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 µg/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 pg/L roust be qualified (estimated) and reported.
If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Asheville Regional Office Aquifer
Protection Supervisor, telephone number (828) 2964500, must be contacted immediately for further instructions regarding any additional follow-up analyses
required.
6. If TOC concentrations greater than 10 mg/1 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 3 and this attachment.
