take immediate corrective actions, including Division required actions, such as the construction of
additional or replacement wastewater treatment or disposal facilities. [15A NCAC 02T .0108(b)(1)(A)]

water resulting from the operation of this facility. [15A NCAC 02T .0108(b)(1)(A)]
3. Groundwater monitoring wells shall be constructed in accordance with 15A NCAC 02C .0108
(Standards of Construction for Wells Other than Water Supply), and any other jurisdictional laws and
regulations pertaining to well construction. [15A NCAC 02C .0108]
4. Wastewater disposal sites permitted on or after December 30, 1983 have a compliance boundary that

compliance boundary shall require corrective action. Division -approved relocation of the compliance
boundary shall be noted in Attachment B. Multiple contiguous properties under common ownership
and permitted for use as a disposal system shall be treated as a single property with regard to
determination of a compliance boundary. [15A NCAC 02L .0106(d)(2), 02L .0107(b), 02T .0105(h),

1. 3 x Year groundwater monitoring shall be conducted in April, August and December; Annual monitoring shall be conducted in December.
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 December only, analyze by one of the following methods:
a. Standard Method 623OD, PQL at 0.5 µg/L or less
b. Standard Method 621 OD, PQL at 0.5 µg/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 µg/L or less
e. Another method with prior approval by the Water Quality Permitting Section Chief
Any method used shall meet the following qualifications:
a. A laboratory shall be DWR certified to run any method used.
b. The method used shall include all the constituents listed in Table VIII of Standard Method 6230D.
c. The method used shall provide a PQL of 0.5 µg/L or less that shall be supported by laboratory proficiency studies as required by the DWR Laboratory Certification Unit. Any constituents
detected above the MDL but below the PQL of 0.5 µg/L shall 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],
shall be contacted immediately 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 shall 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.
Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 1 and this attachment.
