H. PERFORMANCE STANDARDS
1. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
waters or groundwater resulting from the operation of this residuals surface disposal program.
2. No residuals shall be approved for surface disposal in the surface disposal unit.
3. The COMPLIANCE BOUNDARY for residuals surface disposal programs is specified by 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
1. 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/maintained satisfactorily,
including the creation of nuisance conditions, the Permittee shall contact the appropriate Division's
regional office, and take any immediate corrective actions as may be required by the Division.
3. A copy of this permit, 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.
5. 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.
6. A protective vegetative cover shall be established and maintained on the surface disposal unit, berms,
pipe runs, erosion control areas, and surface water diversions. Large trees, shrubs, and other woody
vegetation shall not be allowed to grow on the final cover system of the unit. All areas within the
boundary of the unit shall be kept mowed or otherwise controlled and accessible.

1. Semi-annual monitoring shall be conducted in May & 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 spade 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. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 µg2 or less
b. Standard Method 6210D, PQL at 0.5 ug/L or less
c. EPA Method 8021, Low Concentration, PQL at 0.5 µg2 or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 µg2 or less
e. Another method with prior approval by the Division
Any method used must meet the following qualifications:
a. A laboratory must be D WQ certified to run any method used.
b. The method used must, at a minimum, include all the constituents listed in Table VIII of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 µg2 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 Asheville Regional Office Supervisor, telephone number [phone],
must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. If TOC concentrations greater than 10 mg/I 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.
