II. PERFORMANCE STANDARDS
The reclaimed water utilization facilities (i.e., low rate infiltration ponds and irrigation areas) and
high rate infiltration facilities shall be effectively maintained and operated at all times so that there is
no discharge to the surface waters, nor any contravention of groundwater or surface water standards.
In the event that the facilities fail to perform satisfactorily, including the creation of nuisance
conditions due to improper operation and maintenance, or failure of the reclaimed water utilization
facilities (i.e., low rate infiltration ponds and irrigation areas) and/or high rate infiltration facilities to
adequately assimilate the wastewater, the Permittee shall take immediate corrective actions including
those actions that may be required by the Division, such as the construction of additional or
replacement wastewater treatment and disposal facilities. r.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to ground
or surface waters resulting from the operation of this facility.
3. All wells that are constructed for purposes of groundwater monitoring shall be constructed in
accordance with 15A NCAC 02C .0108 (Standards of Construction for Wells Other than Water
Supply) and any other state and local laws and regulations pertaining to well construction.

infiltration ponds and irrigation areas permitted prior to September 1, 2006) are established at the
property boundary. Any exceedance of standards at the Compliance or Review Boundary shall
require action in accordance with 15A NCAC 02L .0106.
The COMPLIANCE BOUNDARY for the high -rate infiltration facilities is specified by rules in 15A
NCAC 02L, Groundwater Classifications and Standards. These disposal systems were individually
permitted on or after December 30, 1983; therefore, the Compliance Boundary is established at either
250 feet from the waste disposal area, or 50 feet within the property boundary, whichever is closest to
the waste disposal 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.
8. The REVIEW BOUNDARY for the high -rate infiltration facilities is established around the disposal
systems midway between the Compliance Boundary and the perimeter of the waste disposal area.
Any exceedance of standards at the Review Boundary shall require action in accordance with 15A
NCAC 02L .0106.
9. The Permittee shall apply for a permit modification prior to any sale or transfer of property that
affects a compliance boundary to establish a new compliance boundary.
10. In accordance with 15A NCAC 02L .0107(d), no wells, other than monitoring wells, shall be
constructed within the compliance boundary except as provided by 15A NCAC 02L .0107(g).

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. Volatile Organic Compounds (VOC) - In September only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 pg/L or less
b. Standard Method 6210D, PQL at 0.5 µg/L or less
c. EPA Method 8021, Low Concentration, PQL at 0.5 pg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less
C. 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 Table V ilI 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 µg/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 Washington Regional Office Aquifer Protection 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/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.
