4. The issuance of this permit does not exempt the Permittee from complying with any and all statutes,
rules, regulations, or ordinances, which may be imposed by other government agencies (local, state,
and federal) that have jurisdiction. Of particular concern to the Division are applicable river buffer
rules in 15A NCAC 02B .0200, erosion and sedimentation control requirements in 15A NCAC
Chapter 4 and under the Division's General Permit NCG010000, and any requirements pertaining to
wetlands under 15A NCAC 02B .0200 and 02H .0500.
5. In the event there is a desire for the facilities to change ownership, or there is a name change of the
Permittee, a formal permit request must be submitted to the Division on official Division forms,
documentation from the parties involved, and other supporting materials as may be appropriate. The
approval of this request will be considered on its merits and may or may not be approved. The
Permittee of record shall remain fully responsible for compliance until a permit is issued to the new
owner.
6. The Permittee shall retain a set of approved plans and specifications for the life of the facilities
permitted herein.
7. The Permittee shall maintain this permit until all permitted facilities herein are properly closed or
permitted under another permit issued by the appropriate permitting authority.
8. The Permittee must pay the annual fee within 30 days after being billed by the Division. Failure to
pay the fee accordingly may cause the Division to initiate action to revoke this permit pursuant to
15ANCAC 02T .0105(e).

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 pfl shall be made after purging and prior to sampling for the retraining parameters.
3. The measuring points (top of well casing) crall 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 µg/L or less
b. Standard Method 6210D, PQL at 0.5 pg/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/I, 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. Mlle method used must- at a minimum, include all the constituents listed in Table V111 of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 µg/L or less that trust 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.
WQ0033589 Version 1.0 Attachment C Page I of 2

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/i, 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.
