Subject: Permit No. WQ0034367
Northwest Regional Water
Reclamation Facility
Bulk Conjunctive Reclaimed Water
and High -Rate Infiltration System
Onslow County
In accordance with your permit major modification request received May 24, 2011, and
subsequent additional information received August 22, 2011, we are forwarding herewith permit No.
WQ0034367 dated September 9, 2011, to the Onslow Water and Sewer Authority for the construction and
operation of the subject wastewater treatment, bulk conjunctive reclaimed water and high -rate infiltration
facilities.
The modifications to the subject permit are as follows: the construction only of a 1,000,000
gallon per day (GPD) wastewater treatment plant (i.e., Trains IA and 2A), resulting in a total of
2,000,000 GPD of wastewater treatment capacity with 1,000,000 GPD of high -rate infiltration disposal
capacity.
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. On August 2, 2010, this Act was extended
an additional year. The subject permit falls within the scope of this Act and is therefore being
extended to December 31, 2016.
This permit shall be effective from the date of issuance until December 31, 2016, shall void
Pem-dt No. WQ0034367 issued July 2, 2010, and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements listed in Attachments A,
B, C and D for they may differ from the previous permit issuance. Failure to establish an adequate
system for collecting and maintaining the required operational information shall result in future
compliance problems.

I. 3 x Year monitoring shall be conducted in March, July & 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 cacti well shall be measured from the surveyed point on the top of the casing. The measurement
of plI 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 November only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 µg/I, or less
b. Standard Method 6210D, PQL at 0.5 lig/L or less
C. F11A Method 8021, Low Concentration, PQL at 0.5 pg/L or less
d. EI'A 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 UWQ 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 lrg/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 Wilmington Regional Office Aquifer Protection Supervisor, telephone
number [phone], must be contacted immediately for further instructions regarding any additional follow-up analyses required.
fi_ If TOC concentrations greater than 10 xng/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'rOC 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. Iblonitoring wells shall be reported consistent with the nomenclature and location information provided in Figure I and this attachment.
