In accordance with a minor permit modification request received from David S. Briley of
ARCADIS on August 27, 2009, we are forwarding herewith Permit No. WQ0000550, dated October 21,
2009, to Currituck County for the installation and inclusion of a fountain aerator at the Currituck County
Wastewater Treatment Facility and the continued operation of the subject wastewater treatment and
surface irrigation facilities.
The following modifications to the subject permit are as follows: The facility description has been
changed to include; a fountain aerator, and permit conditions have been added to allow its installation.
On August 5, 2009, Session Law 2009-406, entitled "An Act to Extend Certain Government
Approvals Affecting the Development of Real Property Within the State," was enacted by the General
Assembly and signed into law. The Act, known as the Permit Extension Act of 2009, extends the
expiration date of certain government approvals and permits. The subject permit falls within the scope of
this Act and is therefore being extended until December 31, 2015.
This permit shall be effective from the date of issuance until December 31, 2015, shall void
Permit No. WQ0000550 issued January 31, 2008, and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements listed in Attachments A,

a. 3 X year monitoring shall be conducted in March, July & November; Annual monitoring shall be conducted every November.
b. The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be treasured from the surveyed point on the top of the casing.
The measurement of pH shal I be trade after purging and prior to sampling for the remaining parameters.
C. The nieasuring 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) oral] monitoring wells shall be surveyed relative to a co3nrnon datum.
d. Volatile Organic Compounds (VOC) -- In November only, analyze by one of the following methods:
1. Standard Method 6230D, PQL at 0.5 pg/L or less
2. Standard Method 6210D, PQL at 0.5 gg/L or less
3. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less
4. EPA Method 8260, Low Concentration, PQL at 0.5 pg/L or less
S. 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 V111 of Standard Method 6230131.
C. The method used must provide a PQL of 0.5 pg/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.
e. 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 lollot;°-up analyses required.
f IfTOC 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/l, this concentration wil I be taken to
represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TQC concentration in the downgradient wells shall be subject to the
additional sampling and analysis as described above_
g. Monitoring wells shall be reported consistent with the nomenclature and location infonnation provided in Figure 2 and this attachment.
